If such an operation is redone four times for the same magnetic card, or if a predetermined time (about 20 seconds) has elapsed after the first abnormal buzzer 15 rings, the display screen 4 is displayed on the original LCD. The display is switched to 1-1.

From step 100 of the flowchart of FIG.
Reference numeral 115 shows such a series of operation procedures. According to the key storage device of the present invention, by simply causing the card reader 2 to read and scan an electronic card such as a magnetic card or an IC card that each individual already possesses,
The operation procedure for opening the door 19 of the key storage box 1 can be made different, and a wide range can be provided in terms of operation. On the other hand, as an internal switch of the device body,
It is also possible to provide one for this switching.

By the way, the key storage box 1 has a door 19
When the key is opened based on a predetermined operation, the door 19 cannot be closed unless the key once taken out is returned to the predetermined state, and the open state can be maintained. By adopting this structure, it is possible to encourage the key user to prevent the key from being taken away and to make sure that the key is returned. Can be understood at a glance. As a structure for this, for example, the door 19 is always biased in the opening direction by a spring (not shown) or the like, and
As described above, when the door 19 is closed, a pin 22 is provided so as to face the notch 23 provided in the key storage box 1 from the peripheral portion of the door 19, and the pin 22 is connected to a solenoid (not shown). It should be possible to move into the door 19 by the excitation operation. As shown in FIG. 7, two contacts A and B are OR-connected to the solenoid 21 for opening the door 19 so that the solenoid 21 is excited (removal operation of the pin 22) regardless of which one is closed. .

A time chart is shown in FIG. 8. Among them, the A contact is closed at the same time as the opening operation command signal for opening the door 19, which is output after the magnetic card or the personal identification number is verified.
The other B contact is closed when there is no key return signal to the key storage box 1 and each time the door 19 is closed. In addition, as the abnormality alarm output means 12 (see FIG. 2), an alarm means can be provided separately from the abnormality buzzer 15 (see FIG. 3). As shown in FIG. 8, when the door 19 is opened based on a predetermined operation, the alarm means locks the key to the key storage box 1 even if a predetermined time (T2) has elapsed from this time (T0). When the return signal is not transmitted, or when the closing signal for the door 19 is not transmitted, an alarm is issued. This will prevent the key user from removing the key and ensure that the key is returned.
It is possible to prevent the key from being stolen due to forgetting to close the door 19. As the time (T2) until the alarm is issued, in order not to give time to make a duplicate of the key, the time required to go back and forth from the installation location of the key storage box 1 to the door, etc. It is set to have some margin (an arbitrary time with a maximum length of about 3 minutes). In addition, in order to prevent frequent occurrence of alarms, the time (T2) until the alarm is issued is divided into the forecast time (T1) and the main alarm time, and when the forecast time (T1) expires, First, the device abnormality buzzer 15 may be set to ring. Steps 300 to 310 in FIG. 9 are a flowchart showing a series of operation procedures for closing the door 19 of the key storage box 1.

In a building or the like, a security system for automatically issuing an alarm or making an emergency contact when a door door or window after being locked is detected to be broken or pry open or an intruder is detected. It may be provided. In such a case, when the door 19 of the key storage box 1 is opened or the key is taken out by a regular operation using a magnetic card, the security system is automatically released, or
After you have finished using it in a building, etc., and after locking the doors, etc.,
By returning the used key to the key storage box 1, it is possible to make the security system return to its original set state.

The display screen 4 is for executing registration processing.
It is configured to display a guide such as next steps and confirmation items. FIG. 10 systematically shows such a procedure guide message in the order of its development. First, the menu display shown on the LCD-1 is performed. From this state, every time the [*] key of the ten-key pad 3 is pressed, the display is switched to the LCD-11, LCD-111, ...

Therefore, in order to register the card data written in the electronic card such as a magnetic card which is also used for other purposes, the [*] key is operated once from the state where the LCD-1 is displayed. , The display mode of the LCD-11 is switched to the registration mode, and the registration mode is activated. Therefore, the desired registration number (for example, 0
02) is designated and input by the ten keys 3 (see FIG. 10).
(See (a)). If you do not want a specific number (regardless of the number) as the registration number, you can simply operate the [*] key to automatically select the lowest number among the available numbers. It is displayed on the next LCD-111.

Next, according to the display on the LCD-111, the electronic card is passed through the card reader 2 to read and scan the card data. When the scanning and registration are properly performed, a beep is sounded, and then LCD-11
The display indicated by 2 is performed. Since you will be asked for your PIN code here, if necessary, enter an arbitrary four-digit number (eg 1, 2, 3, 4) and operate the [*] key (PIN code). If you don't need, operate only * key). The display of LCD-113 which is switched next is for confirming the registration result, and the registration number and the personal identification number which have been registered immediately before that are displayed. Finally, one of the numeric keys (for example, the [1] key) and the [*] key are operated to complete the registration processing work. After the card data of the electronic card can be registered in this way, the door 19 of the key storage box 1 can be opened and unlocked with this electronic card.

When a registration number (for example, 002) is designated and input according to the display on the LCD-11, if it is determined that another registration data is already written in this number, the registration number is automatically input. The erasure mode for erasing the registration data written in No. 002 is executed (see FIG. 10B). By doing this, if duplicate registration numbers are found, L
There is no need to take the trouble of newly selecting the erasing mode after returning to the display of CD-1, and there is an advantage that the registration processing work can be performed quickly.

Since the setting switch described above is provided inside the main body of the apparatus, it is necessary to unlock the lock device 17 of the front panel 18 (see FIG. 3) with a dedicated key when operating the setting switch. In addition, if you delete all the setting items such as the registration data by the registration as described above at once (for example, when the installation location of the key storage box 1 is changed or when there is a significant personnel movement). Etc.)
In the DIP switch 25 as shown in, for example, 5
It is convenient to have a configuration in which all the data can be erased at once by turning on the numbers 6, 6 and 8 at the same time. Even with such a DIP switch 25,
It is provided inside the device body.
