Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a storage device, and more particularly to a storage device for a rental locker capable of selecting a storage holding state and a storage erasing state of a storage device of a personal identification number.

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. The coin locker can be used easily because it operates the locker's mechanical locking mechanism using the falling motion of coins.
There is a drawback that the key must be carried and the locking mechanism is complicated and is prone to malfunction.

Recently, for example, as shown in Japanese Utility Model Laid-Open No. 61-155566, a rental locker equipped with a numerical electronic lock has been developed in place of the coin control type locking mechanism. 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. The door of the rental locker is provided with a number display section for displaying which button is operated by a light emitting diode (LED) or a liquid crystal panel (LCD) when a push button with a predetermined number or symbol is operated. ing. Therefore, the unlockable personal identification number is displayed on the number display section. This rental locker is used as a keyless locker that does not use coins at golf courses, ski resorts, etc.

The keyless locker includes a plurality of switches for inputting a personal identification number, a storage unit for storing the personal identification number input by these switches, a personal identification number stored in the storage unit, and a collation number input by the switch. It has comparing means for generating a coincidence signal when the personal identification number and the collation number coincide with each other and a lock mechanism for unlocking by the coincidence signal of the comparing means.

Problems to be Solved by the Invention In a rental locker used in a sports club such as a golf course, conventionally, two types of storage devices had to be used. In other words, it is desirable that there are overnight guests and one-day guests at the Golbu ground, and it is desirable that the same locker lock can be used continuously for the overnight guest with the same PIN code. It is desirable to erase. In this respect, conventionally, when the external power supply is cut off, two types of lockers are available, one is a locker for guests that retains the PIN code and the other is a locker for day trips that erases the PIN code. did not become. Therefore, a large number of these two types of rental lockers must be installed in order to accommodate the number of guests and one-day visitors, which not only prolongs the installation period, but also increases prices. Needed a large installation space.

Therefore, an object of the present invention is to provide a storage device for a rental locker that can select a storage holding state and a storage erasing state of a personal identification number in one rental locker.

Means for Solving Problems A rental locker storage device according to the present invention comprises a plurality of switches for inputting a personal identification number, a control device connected to the switches, and a lock mechanism operated by the output of the control device. The control device compares the personal identification number stored by the storage unit for storing the personal identification number input by the switch and the personal identification number stored by the storage unit with the collation number input by the switch, and the personal identification number and the collation number match. And a comparison means for generating a coincidence signal when the comparison means is generated, and in the rental locker unlocked by the lock mechanism when the comparison signal for the comparison means is generated, a backup power source charged from an external power source, and the backup power source. And a storage control switch for controlling the current flowing from the storage device to the storage means of the control device.

By operating the working memory control switch, it is possible to easily select the memory holding state or the memory erasing state of the memory means for storing the personal identification number.

In the above configuration, the user operates the handle 5 to
When the door 2 in the unlocked state is opened and a card is inserted into the card insertion opening provided inside the door 2, the card detection switch 14 is turned on. In this state, the card can be observed from the outside through the card confirmation window 6. Next, when the plurality of switches 3 are pressed in a predetermined order to supply the personal identification number to the control device 10, the temporary storage means in the control device 10 including a RAM or the like stores the 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 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 in this state, the signal from the latch switch 25 causes
The control device 10 operates the solenoid 13 through the differentiating circuit 11 and the driving circuit 12 to lock the door 2.

Next, when the user inputs the reference number with switch 3,
This input signal is compared by the comparison means in the controller 10.
When the input reference number and the personal identification number match, the comparing means generates an output, operates the solenoid 13 through the differentiating circuit 11 and the driving circuit 12, and unlocks the door 2.

In the voltage monitoring circuit 21, the transistor 39 is on and the transistor 40 is off when the circuit is powered on. Therefore, the output terminal 38 has a high level voltage. When the power supply is cut off at night, the external power supply voltage drops, and when the voltage at the non-inverting input of the comparator 36 drops below the voltage of the reference voltage setting circuit 32, the output of the comparator 36 inverts and the transistor 39 is turned off, transistor 40 is turned on, and the output terminal 38 becomes a low level voltage.

The control device 10 detects the state of the memory control switch 23 and the state of the voltage monitoring circuit 21 and automatically performs the operation shown in the operation flow of FIG.

First, the control device 10 detects a voltage drop from the output of the voltage monitoring circuit 20 (step 50). Here, the control device 10
Detects whether the storage control switch 23 is in a storage holding state or a storage erasing state by turning it on or off. When in the backup mode in which the memory is held (step 52), the state of each input / output section is stored in the storage means (step 53), and then the stop mode is shifted (step 54). If it is not the backup mode in step 52, the mode is switched to the stop mode without storing it in the storage means (step 54).

The next day, when the worker turns on the switch and turns on the rental locker, it is determined in step 55 whether the voltage is restored. When voltage is restored, memory control switch
The state of 23 is read (step 56), and it is judged whether or not it is in the backup mode (step 57). When the backup mode is not set, that is, when the memory is erased, the reset circuit 20 is activated (step 60). In the backup mode, that is, in the memory holding state, the memory contents are read from the memory means (step 50) and the state before the voltage drop is restored (step 59).

When the card is removed from the card insertion opening provided inside the door 2, the card detection switch 14 is turned off and the personal identification number is erased. The operation when inserting and removing the card in the card insertion slot is shown in the operation flow of FIG. When the card is inserted into the card insertion slot, the card detection switch 14 is turned on and the insertion of the card is detected (step 61).
In response to the ON signal of the card detection switch 14, the control device 10 composed of the IC is released from the stop mode and shifted from the standby mode to the enable mode (step
62). Therefore, the control device 10 detects the states of the plurality of mode setting switches 24 including the storage control switch 23 (step 63). Next, the user operates the switch 3 to input a desired personal identification number (step 64), and then proceeds to step 65. In step 65, the card input, that is, the state of the card detection switch 14 is detected every 25 ms (step 66). Here, if there is a card, the operation is continued (step 68) and the process returns to step 65, but when the card is removed from the card insertion slot, the mode shifts to the stop mode (step 67) and the control device 10 enters the standby mode. Be shifted.

The above embodiment of the present invention can be modified. For example,
As shown in FIG. 6, it is possible to configure the rental locker storage device of the present invention. In detail, the external power supply 70
A backup power supply 27 and a storage control switch 23 are connected between the control device 10 and the control device 10. The external power supply 70 is a commercial AC power supply 71, a switch 72 connected to the commercial AC power supply 71, and a rectifier circuit connected to the switch 72 and for exchanging AC with DC.
73 and a converter 74 that stabilizes the output of the rectifier circuit 73. The converter 74 is controlled by the OR gate 75.
Connected to 10. Further, the converter 74 is connected to the storage control switch 23, the backup power supply 27, and the OR gate 75 through the diode 76. The memory control switch 23 is a c-point type three-terminal switch. The terminal 23a is connected to the backup power supply 27, the terminal 23b is connected via the resistor 77,
The terminal 23c is connected to the diode 76.

In the above-mentioned configuration, as shown in the figure, the storage control switch 23 is in the storage holding state when the terminals 23a and 23c are connected, and when the switch 72 is in the ON state, the backup power supply 27 is connected to the diode 76 and the storage control switch from the external power supply 70. Charged through 23. Therefore, even if the switch 72 is turned off, the backup power source 27 operates the OR gate.
Power is supplied to the control device 10 through 75, and the contents stored in the storage means are retained. However, when the terminals 23a and 23b of the memory control switch 23 are connected, the memory is erased, and the backup power supply 27 is discharged through the memory control switch 23 and the resistor 77. Therefore, the storage time in the storage means in the control device 10 is held only while the switch 72 is on, that is, while the locker locker is powered on.

Further, the card detection switch 14 may be connected between the external power source 70 and the diode 76 or between the diode 76 and the backup power source 27. Furthermore, a capacitor may be used as the backup power supply 27.

EFFECTS OF THE INVENTION In the storage device for rental lockers of the present invention, the storage holding state and the storage erasing state of the storage means for storing the personal identification number can be easily selected by individually operating the storage control switch in each rental locker. Therefore, it is possible to deal with day-trippers and overnight guests by using only one type of locker without having to install a large number of lockers of two types corresponding to the number of guests and day-trippers. The number of can be reduced.
