The pinion 41 that has not been brought into engagement with the rack 42 on the sub-chassis 10 side.

Further, the tray base 25 moves past the ejectable position (playing position) to a storage position where the tray 24 is stored in the tray holders 5, 5 as shown in FIGS. 11, 12, and 13C. Then, the tray hanger 37 on the upper surface of the tray base 25, the tray 24, and the pinion 41 pivotally supported by the tray base 25 move together with the tray base 25 by a distance l, while the distance l of the pinion 41 on the rack 42 increases.
With only the rotational movement, the tray hanger 37 and the tray 24 that mesh with each other via the pinion 41 and the rack 43 are sent out with the rotation of the pinion 41 and move by the distance l.

Therefore, as shown in FIGS. 13B and 13C, when the tray base 25 moves by the distance 1 from the ejectable position (playing position) to the storage position, the tray hanger 37 and the tray 24 integrated therewith are moved by the distance. The tray 24 is moved by 2 l, and a sufficient horizontal movement amount of the tray 24 can be obtained by such a double speed mechanism.

A rotatable stopper 45 is provided in the concave groove 32 on the left outer side of the tray base 25, and the tray hanger 37 and the tray 24 are integrally formed on the upper surface as shown in FIG. When the tray base 25 is pulled out to the loading / unloading position in the mounted state, the one end surface 45a of the stopper 45 comes into contact with the ridge 33 of the left guide rail 31 of the sub-chassis 10, and the stopper 45 moves counterclockwise. It is made not to rotate. As a result, similarly to a normal disc reproducing apparatus, when the tray base 25 at the loading / unloading position is manually pushed into the apparatus, even if only the tray hanger 37 is pushed in, the stopper 45 which does not rotate does not rotate. Other end
45b comes into contact with the tray 24, and the tray hanger 3 on the upper surface
As shown in FIG. 8, there is no possibility that only the tray 7 and the tray 24 are pushed into the apparatus and the tray base 25 is not pushed into the apparatus.
7. The tray 24 and the tray base 25 are pushed together into the apparatus, that is, to the ejectable position (playing position). When the tray base 25 is completely pushed into the ejectable position (performance position), the ninth
As shown in the figure, the notch 46 formed at the loading direction side end of the ridge 33 of the left guide rail 31 allows
The engagement between the one end surface 45a of the stopper 45 and the ridge 33 releases the stopper 45 so that the stopper 45 can be rotated in the counterclockwise direction. As a result, the tray hanger 37 on the tray base 25 at the ejectable position (playing position) can be obtained. And the tray 24 can be moved to the storage position.

Further, the reproducing drive unit M ₃ are, intended to reproduce the disc placed on the tray 24 in ejectable position described above (playing position), as shown in FIG. 6 and FIG. 10, the sub A turntable 4 is mounted on a chassis 47 supported on the lower surface of the chassis 10 with the tray holder 5 side as a pivot.

Then, when the disc reproduction, the entire chassis 47 of the reproduction drive unit M ₃ is moved upward, the disc on the tray 24 is lifted from the bottom turntable 48, clamper unit disposed above the sub-chassis 10 It is held down by 49 and is driven to rotate.

In addition, the disc reproduced as described above is loaded into the tray storage section constituted by the tray holder 5 as shown in FIGS. 11 and 12 by the above-described loading operation together with the tray 24 on which the disc is placed. 4. As described above, the tray storage section 4 has a storage shelf capable of storing 11 trays 24, and always stores 10 trays 24 regardless of the presence or absence of a disk. The tray hanger 37 is mounted on the tray base 25 at an ejectable position (performance position) as an empty tray. In addition, the sub-chassis 10 that moves up and down with the tray hanger 37 and the tray base 25 on which the tray 24 is placed is mounted on the upper surface thereof, as shown in FIG. 3 and FIG. Since the trajectory moves along an arc-shaped trajectory centered on the pivot pins 9, 9, the ten trays 24 stored in the tray storage portion 4 by the above-described loading operation of the tray base 25 are also shown in FIG. As shown in FIG. 7, the layers are stacked in a substantially circular arc shape. For this reason, the tray holder 5 that constitutes the tray storage section 4 has a shape in which the front side of the apparatus swells.

Further, the vertical movement of the sub-chassis 10 is performed not only at the ejectable position (playing position) shown in FIG. 10 but also at the storage position shown in FIG. . In the case of vertically moving at the storage position, as shown in FIG. 16, it is assumed that 11 trays 24 including one empty tray are stored in the storage shelves of the tray storage unit 4 respectively. Therefore, only the tray hanger 37 placed on the tray base 25 is moved up and down by the sub-chassis 10 so that the notches 39, 39 ... of the stored trays 24, 24 ... It is made to move while passing through. Then, the tray hanger 37 stopped at the predetermined tray 24 position pulls out the predetermined tray 24 so as to grasp it from the drawer side, and conveys the drawn tray as an empty tray to the above-described ejectable position (playing position). It has been made like that.

In this apparatus, for example, an optical sensor is used, and the sub-chassis 10 is located at the above-described ejectable position (where the tray base 25 placed on the sub-chassis 10 corresponds to the front opening 44 of the apparatus). A position detection sensor (not shown) of a mechanical unit for detecting whether or not the disk is located, and a disk presence / absence detection sensor (not shown) for detecting whether or not a disk is placed on the tray at the ejectable position ) Is provided, and signals from these sensors are sent to a control circuit described later.

 Next, the circuit configuration of the present apparatus will be described.

As shown in FIG. 18, the information recorded on the disc is read by an optical pickup 50, and the signal from the optical pickup 50 is converted into an audio signal via a signal processing circuit 51. The converted signal is amplified by the amplifier 52 and sent to the speaker 53. The signal processing circuit 51 also outputs a play end signal based on the signal from the pickup.
It is sent to the control circuit 54 which operates as shown in the flowcharts of FIGS. 19 and 20.

Further, the control circuit 54 has a mechanism for detecting whether or not the tray base 25 placed on the sub-chassis 10 that moves up and down is located at a position corresponding to the opening 44 on the front of the apparatus, that is, at an ejectable position. Signals from a position detection sensor 55 of the unit, a disk presence / absence detection sensor 56 for detecting whether or not a disk is placed on the tray 24, and an operation key 57 provided on the front of the apparatus. In response to these input signals, the control circuit 54 performs an operation to be described later, and outputs a predetermined command signal to the mechanical unit drive circuit 58.

Next, the operation of the present apparatus based on the above configuration will be described with reference to FIGS.

As described above, this apparatus has 11 trays, and has 11 storage shelves in the tray storage section.
There are ten trays stored in the place, and ten desired discs can be stocked, and the eleventh tray is an empty tray, and this empty tray comes out of the device and the normal single player This enables the same performance as.

That is, the operation of the operation keys on the front of the apparatus, the first tray is pulled out, and the desired disc is placed on the protruding tray and played, which is exactly the same operation as a normal single player. By issuing a stock command to the played disk, the tray on which the disk is placed is stored in the first stage of the tray storage unit, and the second stage tray is transported to an ejectable position to be in a standby state. By repeating this operation, ten discs can be stored, and only the eleventh tray can perform the same operation as a normal single player, and becomes an empty tray that cannot be stored in the tray storage part. It has become.

Further, information on the ten stored disks described later can be stored, and the disks can be taken out one by one and replaced with another disk. The sub-chassis 10 mounted with the various mechanical units described above and moved in the vertical direction, and the tray base 25 and the tray hanger 37 for moving the horizontal direction on the sub-chassis 10 to pull out and store the tray 24, Thus, an autochanger device having a single-player feeling capable of performing the above-described operation is configured.

First, the playing operation of the stored disc will be described with reference to FIG.

In the present apparatus, a stock command has been issued to the disc by the above-described operation, and ten trays 24 on which discs have been stored are already stored in the tray storage unit 4, and various information on the stored disks is also stored. It is assumed that

In order to play and play a desired disc among those stored in such a state, first, the operation keys 57 on the front of the apparatus are used.
To input a play command and a pre-stored registration number corresponding to the disc to be played (step 1). Then, as described above, the tray base 25 placed on the sub-chassis 10 is
Based on a signal from the position corresponding to the position 44, that is, the position detection sensor 55 of the mechanical section for detecting whether or not the eject tray is at the ejectable position, it is determined whether or not the above-mentioned 11th empty tray is at the ejectable position (step 2) If it is in the ejectable position, the sub-chassis 10 moves up and down and the tray base 25 moves horizontally, and the empty tray is stored in the empty storage shelf of the tray storage section 4 at only one place. (Step 3). Then, at the so-called storage position where the tray base 25 is moved to the storage section side (in this state, all the 11 trays 24 are stored in the tray storage section 4), the sub-chassis 10 is designated by key input. The disc with the number is moved to the tray position where the disc is located, the tray base 25 is operated at the height position, and the tray on which the specified disc is placed is pulled out (step 4), and the performance is performed at the height position (step 4). Step 5). Therefore, in the case of the present apparatus, the position where the sub-chassis 10 is moved and the tray 24 is pulled out is the playing position, and one position of the playing position is the ejectable position.

When the performance ends and a play end signal is output from the signal processing circuit 51 (step 6), the played tray 24 is stored in the original storage shelf (step 7), and the tray storage section 4 is emptied. The empty tray stored in the place is in the state before the key input, that is, the subchassis 10 with the empty tray
Moves to an ejectable position (step 8).

Next, the storing operation of the disk will be described with reference to FIG.

In this case, it is assumed that some trays 24 on which disks are loaded are stored in the tray storage unit 4.

In this state, the new disc was played as a single player using the eleventh empty tray at the ejectable position, and the disc was liked. One of the discs already containing this new disc was In the case of replacement, first, the stock command and the registration number of the new disk are input by the operation keys 57 (step 1). Then, the disk presence sensor on the tray
From the signal from 56, it is determined whether or not a new disk is loaded on the empty tray (step 2). If a disk is loaded, the number of the new disk is then checked against various information of the disk already stored. It is determined whether or not the registration number entered as a key is empty (Step 3).

If the registration number is vacant, the tray on which the new disk at the ejectable position is placed is stored in the empty space of the tray storage section 4, and the keyed registration number and the information of the new disk are stored. 4). Here, the stored disc information is so-called TOC information indicating the contents of the disc, such as the playing time of the disc. And there is no registration number in the tray storage section yet,
That is, an arbitrary tray 24 on which no disk is loaded is transported to the above-described ejectable position as a new empty tray (step 5).

If the registration number is already used, that is, if a disk having the registration number entered by key is already stored, the information of the disk with the old registration number is erased together with the registration number, and the old disk is loaded. The new tray 24 acts as a new empty tray (step 6).
Then, the empty tray at the ejectable position on which the new disk is placed is stored in an empty place of the tray storage unit 4, and the key-input registration number and the information of the new disk are stored (step 7). Further, the tray 24 acting as a new empty tray on which the old disk of the old registration number from which all the stored information has been erased is carried to the above-described ejectable position as the eleventh empty tray (step 8). .

In the present embodiment, as shown in FIG. 17, the desired storage of the sub-chassis 10 by the combination of the vertical movement of the sub-chassis 10 and the horizontal movement of the tray base 25 placed on the sub-chassis 10 is achieved. Can be selected and reproduced, and the stored disks can be replaced one by one. Also, discs other than the stored disc can be reproduced as a normal single player. Until a stored disc is taken out of the apparatus, information on the disc is completely stored, and a plurality of discs input each time one disc is replaced, as in a conventional magazine type autochanger apparatus. Information does not disappear.

Therefore, in the present embodiment, it is possible to operate as a single player and store 10 discs in the apparatus, and the performance and storage can be freely performed only by placing the discs to be stored on the tray that has come out of the apparatus. What can be done. Further, in the same manner as in a normal autochanger device, random or continuous performance of ten discs can be performed, and a part of a favorite disc can be performed.

In addition, discs other than the 10 stored discs can be played and played in the same way as a normal single player using the 11th empty tray, and the information on the 10 stored discs is completely The input information does not disappear until the disk is taken out of the apparatus.

In addition, if you are not playing, you can always insert a disc
The discs can be replaced one by one, the old disc stored in the apparatus can be replaced with a new disc, and since the eleventh tray is provided, several kinds of discs can be mixed.

〔The invention's effect〕

As described above, the disk autochanger device according to the present invention can select and reproduce a desired disk stored by an external operation, and can exchange stored disks one by one, and until any stored disk is removed. This has the effect that information on the disc can be completely stored.
