FIG. 51 is a prior application filed by the present applicant,
1 shows a schematic configuration of an autochanger device 1 disclosed in Japanese Patent Application Laid-Open No. H10-3734. The autochanger device 1 has a housing 2 with standardized dimensions, also referred to as, for example, a 1DIN size, so that it can be mounted on a dashboard or the like near the driver's seat of an automobile. The size of the housing 2 is, for example, about 18 cm in width, 17 cm in depth, and about 5 cm in height. A stocker 3 is installed in the housing 2 and can store a plurality of compact disks (CDs) 4. CD4 has a disk shape with an outer diameter of about 12 cm and a thickness of about 1.2 mm, and information is recorded at a high density on its surface. The PU unit 5 mounts the CD 4 and reproduces information. As a recording medium, a recording medium such as a CD-R or a CD-RW capable of recording information is used, and information can be recorded if the PU unit 5 has a function capable of recording information. The PU unit 5 is provided on a gantry 6 that moves up and down in the housing 2. In the housing 2, the stocker 3 and the gantry 6 are elastically supported by the floating mechanism 7 in order to reduce the influence of external vibration and impact. A spring and a damper are combined with the floating mechanism 7.

An arbitrary storage position can be selected, and the selected storage position can be divided in the thickness direction of the CD 4 to make a space. The PU unit 5 is a moving mechanism provided on the gantry 6 and can enter the space in the stocker 3 divided by the dividing mechanism 8. The operations of the PU unit 5, the gantry 6, and the dividing mechanism 8 are controlled by the control circuit 9.

[0005] The floating mechanism 7 resiliently supports the entire chassis 10 including the stocker 3 and the gantry 6 so as to be floating with respect to the housing 2. In the floating state, the housing 2 and the internal mechanism attached to the chassis 10 are relatively displaced. Therefore, the floating state can be released by mechanically restraining the lock claw 11. An opening 13 having a shutter 12 is provided on the operation surface side of the housing 2 so that the CD 4 can be inserted or ejected. The shutter 12 closes the opening 13 when one CD 4 is in a transport state or a reproduction state inside the housing 2 in order to prevent the CD 4 from being double-inserted. When the CD 4 inserted through the opening 13 is transported to the stocker 3 or the CD 4 in the stocker 3 is discharged to the outside through the opening 13, the transport roller 14 is driven to rotate and the CD 4 is rotated.

When the CD 4 is inserted or ejected, the pedestal 6 is displaced up and down so that the transport roller 14 matches the position of the opening 13. When the CD 4 is reproduced, the PU unit 5 is moved with respect to the CD 4 stored in the stocker 3. When the position of the transport roller 14 is adjusted to the position of the opening 13 of the housing 2, the chassis 10 including the gantry 6 releases the floating state by the floating mechanism 7 by restraining the lock claw 11 and releases the CD 4 smoothly. Locked for insertion and ejection.

[0006]

In the autochanger device 1 of the prior application as shown in FIG. 51, the entire chassis 10 including the internal mechanism is floated with respect to the housing 2 by the floating mechanism 7, In order to solve the problem, the lock claw 11 is provided so that the entire floating state of the chassis 10 can be released. When the chassis 10 is in a floating state, the chassis 1 is within a certain range inside the housing 2.
0 must be displaceable. Therefore, a gap must be secured between the housing 2 and the chassis 10, and the housing 2
If the external dimensions of the chassis 10 are limited to a standard size, the size of the chassis 10 is limited, and the internal mechanism must be downsized. In particular, in the in-vehicle autochanger device 11, the stocker 3, the PU unit 5, the transport rollers 14, and the like must be installed in the housing 2 where there is no room for arranging two CDs 24 two-dimensionally. .
