Abstract

PURPOSE:To make it possible to insert only a specified key control member into a conforming key control insertion part in simple and low cost structure. CONSTITUTION:There are formed a plurality of key control insertion parts 5 into which a plurality of key 20-mounted key control members 4 are inserted. A locking and unlocking mechanism 26 for the key control members 4 is installed where each key control insertion member 4 is inserted into each key control insertion part 5. The key control insertion members 4 are made of a plate material having a specified thickness. An engagement groove 21 is formed on the end of the plate material at its thickness direction oriented at the insertion direction to the key control insertion parts 5. Each engagement groove 21 for the key control insertion member 4 is formed into different shape for every key control insertion member 4 while a regulating projection 22, which corresponds to the position of the insertion-allowable engagement groove 21 of the key control member 4 is installed to each key control insertion part 5. This simple construction makes it possible to inhibit the insertion of different keys into the key control insertion parts. It is also possible to change the key control members easily.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to, for example, a key for operating a cash handling machine or a tailor's machine installed in a financial institution, or a key for a rental vehicle, a company car or other vehicles, a hotel. The present invention relates to a key management member insertion control device for a key management machine, in which a key or the like in a room is attached to a key management member such as a key ring, and the key management member is inserted and locked in a key management member insertion portion of the key management machine.

[0002]

2. Description of the Related Art A conventional key management machine of this type is disclosed in
No. 56792, an insertion portion of a key management member such as a key holder to which a key is attached is formed corresponding to each key, and the key management member inserted in this insertion portion is locked individually. , A structure provided with a locking / unlocking mechanism for unlocking was adopted.

The key management member forms a cylindrical portion to be inserted into the key management member insertion hole, and the diameter of the cylindrical portion is
The key management member can be inserted only into the corresponding key management member insertion portion by changing the wall thickness and the size and shape of the protrusions provided on the inner circumference and the outer circumference of the tubular portion.

[0004]

In the key management machine having the above-mentioned conventional structure, the key management member has to form the key management member insertion hole according to the key management member, and when the key management member is lost. When preparing a new key management member, the range of specification changes of the key management member is limited, and in order to expand the range of specification changes of the key management member, the key management member insertion hole must be changed. However, there is a problem that the change work is complicated and expensive.

Although it is possible to insert a key management member like a general lock but not lock it when a different key management member is inserted, it is possible to insert a different key management member. As a result, the key management member insertion hole is easily damaged, and when the key management member is inserted into a different key management member insertion hole, if the key management member cannot be locked, the operator cannot It may cause a malfunction of the key unlocking mechanism such as re-inserting the key management member many times in mistake of misoperation or rocking the key management member in the insertion hole. There is a problem to lose.

Therefore, a mechanism for discriminating whether or not a proper key management member has been inserted into the key management member insertion hole may be provided so that the display and alarm device can be activated when different key management members are inserted. It is conceivable, but there is a problem that it becomes expensive.

The present invention has been made in view of the above problems, and a key management member insertion of a key management machine in which only a predetermined key management member can be inserted into a corresponding key management member insertion portion by a simple and inexpensive structure. A control device is provided.

[0008]

The manager's card is an initial operation, a door. Use permission operation mode enabling unlocking of body 2, management registration mode including administrator registration mode, security guard registration mode, and key user registration mode, normal operation mode for removing key management member 4, door lock It becomes possible to operate the print mode and print mode.

Further, the guard card can be operated in the initial operation, the operation mode in which the door 2 can be unlocked, and the normal operation mode in which the key management member 4 is removed.

Further, the key user card is used for initial operation,
It is possible to operate the normal operation mode of removing the key management member 4 and the door lock mode when all the key management members 4 are inserted.

Next, the operation of this embodiment will be described.

The usage mode is set by the first mode in which only the card is used, the second mode by the card and the secret code, the third mode by the card and the code number, and the fourth mode by the card, the secret code and the code number. The mode and the fifth mode based only on the code number can be selected.

When the output from the control unit 60 is an administrator permission signal or a guard permission signal, the electric drive unit 70
The solenoid 54 is excited, the locking plate 51 is moved in the unlocking direction, and the door 2 is opened.

When the key management member 4 is pulled out, if the output from the control unit 60 is an administrator permission signal, a security guard permission signal or a key user permission signal in the initial operation. When the door 2 is unlocked and the completion key of the operation unit 61 is operated, the solenoid 28 for releasing the locking / unlocking lever 26 of the key management member 4 corresponding to the key registered in the key user card. Is excited, and the corresponding display unit 6 is lit in green. When the desired key management member 4 is pulled out in this state, the display unit 6 lights up in red. Then, when all the key management members 4 have been removed, a standby state is set. Also,
If some of the key management members 4 are not removed and the key management members 4 are subsequently removed and all the key management members 4 are removed, operating the completion key of the operation unit 61 outputs the output of the control unit 60. The solenoid 28 that holds the locking / unlocking lever 26 of the key management member locking device 66 in the unlocked position is de-energized, and the locking / unlocking lever is released.
Reference numeral 26 holds the key management member 4 inserted in the insertion portion 5 at a position for locking.

When each of the key management members 4 is inserted into the key management member insertion portion 5, the locking / unlocking claw portion 25 of the locking / unlocking lever 26 is inserted.
Is engaged with the locking recess 23 of the key management member 4 to lock the key management member. At this time, the key management member 4 is inserted only when the engagement groove 21 of the key management member 4 and the restriction projection 22 are engaged,
When the engagement groove 21 of the key management member 4 and the restriction projection 22 do not match, the key management member 4 is not inserted.

Further, all the key management members 4 are returned,
When the door body 2 is closed, the detection protrusion 13 of the door body 2 is inserted into the door body closing detection hole 12 of the door body open / close detection unit 63, and the door body 2 is closed.
Detects that the is closed. And all the key management members 4
When each micro switch 35 detects the return of the above, the solenoid 54 of the electric drive unit 70 is de-energized, and the door body 2 is locked. Also, all the keys are not returned and the door body 2
The buzzer will sound when closed, and the administrator will insert the administrator card or enter the security code or code number, and the buzzer will stop operating, and the solenoid 54 of the electric drive unit 70 will be de-energized and the door will be closed. Body 2 is locked.
