Description

FIELD OF THE INVENTION This invention relates to a card detection device, and more particularly to a keyless lender locker control device that is shifted to an enterable operating mode of a number input switch immediately after detecting a card.

BACKGROUND OF THE INVENTION Various types of rental lockers are currently in use.
For example, coin lockers that insert coins into holes provided at predetermined positions of rental lockers are widely used in various public places such as stations, parks, and sports clubs. Further, recently, as disclosed in, for example, Japanese Utility Model Laid-Open No. 61-155568, a keyless rental locker equipped with a numerical electronic lock has been developed in place of the coin control type locking device. In this numerical electronic lock, an unlocking signal is generated when a plurality of push buttons constituting a switch are pressed in a predetermined order, and the door of the rental locker can be opened. When a push button with a predetermined number or symbol is operated on the door of the rental locker, it is determined which button is operated by a light emitting diode (LE).
D) or a liquid crystal panel (LCD) is provided with a number display section for displaying numbers. Therefore, the unlockable personal identification number is displayed on the number display section. This type of rental locker is used as a keyless rental locker that does not use coins at golf courses, ski resorts, and the like.

The keyless rental locker has a plurality of number input switches for inputting a personal identification number, a storage means for storing the personal identification number input by the number input switch, and a personal identification number and a number input switch stored in the storage means. The comparison means compares the collation number with each other and generates a coincidence signal when the personal identification number coincides with the collation number, and a lock device that unlocks with the coincidence signal of the comparison means.

Problems to be solved by the invention Keyless rental lockers used in sports clubs such as golf courses turn on the power with the inserted card when the card is inserted into the card insertion slot provided on the door. It is configured. For this reason, when a plurality of users insert the card into the card insertion slot at the same time, the solenoids of a plurality of rental lockers are activated at the same time, and there is a risk that a large amount of current may momentarily flow. In order to prevent such a danger, even if a timer is built into the control device of each rental locker and the card is inserted into the card insertion slot, the control device will operate if the delay time set by the timer does not elapse. Did not shift to a possible operating mode. Therefore, during this delay time, even if the number input switch is operated, the input cannot be accepted by the control device, so that the user has to wait for about one minute after the delay time elapses.

Further, in the past, since the storage of the personal identification number is held in the storage device provided in the keyless rental locker, it is necessary to constantly supply current to all the keyless rental lockers regardless of whether or not they are used, thus saving power. I couldn't plan.

Therefore, an object of the present invention is to provide a keyless rental locker control device capable of saving power while retaining the memory of a personal identification number.

A keyless rental locker control device according to the present invention is a door attached to a rental locker, a card insertion opening provided on the door, a plurality of number input switches attached to the door, and a door. A solenoid is connected to a lock device for locking or unlocking, and a control device for energizing the solenoid when the number input switches are operated in a predetermined order. The control device has storage means for storing the number input by the number input switch. This keyless rental locker control device further detects a card inserted in the card insertion slot and gives a card insertion signal to the control device, and a charging device connected to the control device and charged when the card insertion signal is generated. When the control power supply is switched from the standby mode to the operation mode when the backup power supply and the card insertion signal of the card detection switch are received,
When the card insertion signal of the card detection switch disappears,
And a card switching means for switching the control device from the operation mode to the standby mode. When the power from the external power source to the control device is cut off, the power for holding the memory is supplied from the backup power source to the storage means.

When a card having a specific shape is inserted into the card insertion opening provided on the door, the card detection switch is operated by the inserted card, and the card detection switch generates a card insertion signal to the control device. Further, when the card insertion signal of the card detection switch is generated, the mode switching unit switches the control device from the standby mode to the operation mode and also supplies power to the backup power source. Next, when the operator operates the plurality of number input switches attached to the door in a predetermined order, the secret code generated by the number input switches is given to the control device. The control device temporarily stores this personal identification number in the storage means. When the door is tightened and the handle is rotated to the locking position in this state, the control device gives an operation signal to the solenoid, and the locking device is automatically locked.

Thereafter, when the operator inputs the same number as the personal identification number from the number input switch, the inputted number is compared with the personal identification number stored in the storage means in the control device, and a coincidence signal is generated. Therefore, the control device gives an actuation signal to the solenoid, the locking device is unlocked, and the door can be opened. When the card insertion signal of the card detection switch disappears, the mode switching means switches the control device from the operation mode to the standby mode.

Further, at night, the power supply to the keyless locker is stopped, and the power from the external power supply to the control device is shut off.
When the power from the external power source to the control device is cut off, the power for holding the memory is supplied from the backup power source to the storage means, so that the storage of the personal identification number is held in the storage means.

A latch switch 25 for detecting whether or not it is connected to a buzzer 26 that produces a sound when the number input switch 3 is pressed. On the opposite side of the card detection switch 14 provided in the card insertion slot 9 (FIG. 3), a card identification switch 14a for detecting the presence or absence of the cutout portion 8a of the card 8 is provided. As the card identification switch 14a, a switch having the same structure as the card detection switch 14 can be used.

The initial reset circuit 20 is provided with an initial reset switch (not shown) and is connected with a backup power supply 27. The backup power supply 27 is charged from the control device 10 by the ON signal of the card detection switch 14 when the card is inserted into the card insertion slot. When the power from the external power source to the control device 10 is cut off,
The storage means in the control device 10 is a backup power source 27.
Power is supplied from the memory and the memory is retained. The card detection switch 14 is turned on when a card is inserted and generates a card insertion signal. When the card detection switch 14 generates a card insertion signal, the mode switching means switches the control device 10 from the standby mode to the operation mode. Further, the backup power supply 27 is charged through the control device 10.

As shown in FIG. 4, the latch 28 is rotatably mounted on a shaft 33 attached to the door 2 and the shaft 33 is connected to the handle 5. When the latch 28 rotates, the latch 28 moves in and out of the hole 2 a of the door 2. The lock device 7 is the master key 2

A rod 35 that is movable between a blocking lock position [Fig. 4 (C)] and an unlock position [Fig. 4 (B)] where the locking with the latch 28 is released; A solenoid 13 that electrically operates 35 and a latch switch 25 that is disposed adjacent to the latch 28 and that detects the locked and unlocked states of the latch 28 are provided.

In the above configuration, when the user operates the handle 5 to open the unlocked door 2 and insert the card 8 into the card insertion opening 9 provided inside the door 2 (FIG. 3), the card detection switch 14 is turned on and a card insertion signal is generated. In this state, the card 8 can be observed from the outside through the card confirmation window 6. Next, the plurality of number input switches 3 are pressed in a predetermined order to input the personal identification number.
When it is supplied to 0, the temporary storage means in the control device 10 composed of a RAM or the like stores this personal identification number. Meanwhile, the personal identification number is displayed on the electric display unit 4. When the input of the personal identification number is completed, one of the number input switches 3 is pressed to complete the storage in the storage means in the control device 10. When the handle 5 is rotated to the locking position shown in FIG. 4C in this state, the control device 10 receives the signal from the latch switch 25 and causes the solenoid 13 to operate through the differentiating circuit 11 and the driving circuit 12.
Is operated to move the rod 35 to an upper locking position where it locks with the latch 28 to lock the door 2.

Next, when the user inputs the reference number with the number input switch 3, this input signal is compared by the comparison means in the control device 10. When the input reference number matches the personal identification number, the comparing means generates an output, operates the solenoid 13 through the differentiating circuit 11 and the driving circuit 12, and latches 28.
The lock device 7 is unlocked by moving the rod 35 to the lower non-locking position where the engagement with is released (FIG. 4 (B)).

As shown in FIG. 5, the card detection switch 14 is connected to an input port of the control device 10 via an inverter 30 and one terminal 32 connected to a power supply via a resistor 31, and the other terminal 32 grounded. And the terminal 33 of. Since the card detection switch 14 is normally off and provides a high level input to the inverter 30, the inverter 30 provides a low level output to the controller 10. When the card 8 is inserted into the card insertion slot 9, the card detection switch 14 is switched from the off state to the on state by the card 8. Therefore, the low level input is given to the inverter 30, and the high level output from the inverter 30 is sent to the control device 10 as a card insertion signal. When the control device 10 detects the card insertion signal of the card detection switch 14, the control device 10 shifts to an operation mode in which the number input switch 3 can be input.

The operation of the control device 10 will be described with reference to the time chart shown in FIG. 6. Before the card 8 is inserted into the card insertion slot 9, the card detection switch 14 is off and the control device 10 by the card detection switch 14 has a low level. Is supplied, the controller 10 is maintained in the standby mode. When the card 8 is inserted into the card insertion slot 9, the card detection switch 14 is turned on, and a high level card insertion signal is supplied to the control device 10 by the card detection switch 14, so that the control device 10 is shifted to the operation mode. It Further, when the card 8 is pulled out from the card insertion slot 9, the card detection switch 14 is turned off and a low level signal is supplied to the control device 10 by the card detection switch 14, so that the control device 10 is shifted to the standby mode. It This can be achieved by program-controlling the control device 10 including a microcomputer or the like.

Since the personal identification number can be input by the number input switch 3 while the control device 10 is shifted to the operation mode, the user can quickly use the rental locker.

The above embodiments of this invention can be modified. For example, the inverter 30 may be omitted and the on / off state of the card detection switch 14 may be detected by the control device 10.
In this case, the card detection switch 14 may be a normally closed switch and may be turned off when the card 8 is inserted.

Effect of the Invention In the keyless rental rocker control device of the present invention, when the card insertion signal of the card detection switch disappears, the control device is switched from the operation mode to the standby mode to save power and the power from the external power source to the control device is saved. When the power supply is cut off, the power from the backup power supply has the effect of saving the power consumption while maintaining the storage of the storage means.
