In the standby screen of FIG. 7, the card of the user who takes out the key 23 is passed through the card reader 87, and the user inputs the personal identification number on the personal identification number input screen that is displayed thereafter, and the user information is authenticated. As a result, the holder extraction selection screen shown in FIG. 12A is displayed.

In the selection screen of FIG. 12(a), a list of selection buttons, which are arranged corresponding to the arrangement of the actual lock mechanisms 25 provided in the storage 16 and are numbered for each lock mechanism 25, is displayed in advance. The selection button corresponding to the key 23 of the registered user who has the extraction authority is displayed in a display form different from that of the selection button corresponding to the key 23 that does not have the extraction authority. In the selection screen of FIG. 12A, the colors of the selection buttons Nos. 1 to 3 to which the user has the extraction authority are displayed differently from the other selection buttons. Further, among the keys 23 having the take-out authority, the number selection button of the lock mechanism 25 in which the key 23 is in the take-out state and the number selection button of the lock mechanism 25 in which the key 23 can be taken out are displayed in different colors. For example, the selection button corresponding to the lock mechanism 25 in which the key 23 is in the extraction state is displayed in blue, the selection button corresponding to the lock mechanism 25 in which the key 23 can be extracted is displayed in yellow, and the selection button without the extraction authority is Displayed in white.

At this time, as shown in FIG. 12B, in the storage 16 of the key management machine main body 11, the display form of the display unit 66 of each lock mechanism 25 is synchronized. For example, the display unit 66 of the lock mechanism 25 in which the key 23 is in the removal state is lit in blue, the display unit 66 of the lock mechanism 25 in which the key 23 can be removed is lit or blinking in yellow, and the lock mechanism 25 without the removal authority is present. The display unit 66 of is kept off.

As a result, the user can easily confirm the key 23 having the take-out authority and the presence/absence of the key 23. The location of the key 23 can be easily confirmed.

Then, after the selection is performed on the selection screen of FIG. 12(a), the confirmation operation is performed to drive the solenoid 60 of the selected locking mechanism 25 and the lever 57 to the locked position, as shown in FIG. 4(a). Then, the lock of the key holder 26 is released by swinging to the unlock position, and the user can remove the key holder 26. The driving of the solenoid 60 is stopped when the detection unit 65 detects that the key holder 26 has been pulled out, or when a predetermined time elapses. When the driving of the solenoid 60 is stopped, as shown in FIG. 4(c), even when the key holder 26 is pulled out, the lever 57 is brought into contact with the stopper 62 by the spring urging, that is, substantially the same position as the locking position. Rock.

When the detection unit 65 detects that the key holder 26 has been removed from the lock mechanism 25, the storage unit 88 stores a history of extraction information including the extraction date and time, user information, and key information.

Further, the operation of taking out the key 23 which requires the approval of the administrator will be described.

Even if the user selects the selection button on the selection screen of FIG. 12(a) and confirms the key 23 as described above, if the key 23 is set to require approval by the administrator, the lock mechanism is set. 25 does not unlock and the approval screen for the administrator is displayed. After the card information and the personal identification number are input and approved by the administrator, a selection screen for the administrator similar to the selection screen of FIG. 12A is displayed. In this selection screen for the administrator, the selection buttons that are selected by the user and require approval by the administrator are displayed in a display form different from that of the other selection buttons. When the administrator selects a selection button that requires approval, the display form of the selection button is changed. For example, when the selection button selected by the user is displayed in yellow, the administrator selects the selection button to display in green.

At this time, in the storage 16 of the key management machine main body 11, the display form of the display unit 66 of each lock mechanism 25 is synchronized. For example, the display portion 66 of the lock mechanism 25 selected by the user is lit or blinked in yellow, and the display portion 66 of the selected lock mechanism 25 is changed from yellow to green when the administrator selects the selection button. It will be lit or blinking.

This allows the administrator to confirm whether or not the selection button has been selected, and prevent an operation error.

The administrator unlocks the selected lock mechanism 25 by performing a confirming operation after the selection on the selection screen for the administrator. This makes it possible to take out the key 23 that requires approval.

Next, the operation of returning the key 23 will be described.

As shown in FIG. 4C, the key holder 26 of the key 23 to be returned is inserted into the insertion opening 56 of the lock mechanism 25. At this time, the claw 59 of the lever 57 stopped at the substantially same position as the locked position by the stopper 62 projects into the insertion port 56, but the key holder 26 abuts the inclined surface of the claw 59 and the key holder 26 By pushing up the claw portion 59 against the spring bias, the key holder 26 can be inserted toward the lockable position on the inner side of the insertion opening 56.

If the key holder 26 inserted in the insertion opening 56 is of a type compatible with the erroneous insertion prevention mechanism 63 of the lock mechanism 25, the pins of the erroneous insertion prevention mechanism 63 are inserted into the holes 52 of the key holder 26 so that the key holder 26 is It can be inserted up to the lockable position. When the key holder 26 is inserted to the lockable position, the pawl portion 59 of the lever 57 fits into the locking groove 40 of the key holder 26 by the spring bias, and the key holder 26 is locked.

On the other hand, in the case of the incompatible type, the end face of the erroneous insertion prevention portion 33 and the tip of the pin come into contact with each other, and the key holder 26 cannot be inserted to the lockable position. Therefore, erroneous insertion of the key holder 26 into the incompatible lock mechanism 25 can be prevented.

Further, although the return operation described here is a case of normal operation, it may be a return approval operation that requires an approval operation to return the key 23. In this case, as shown in FIG. 4(d), the stopper 62 is not used, and after the key holder 26 is pulled out, the lever 57 swinging by the spring bias is larger in the insertion opening 56 than in the locked position. invade. Therefore, when the key holder 26 is inserted into the insertion opening 56 during the return operation, the end surface of the key holder 26 in the insertion direction comes into contact with the tip end portion of the lever 57, and the insertion into the lockable position is restricted. In this case, the card of the returning user is passed through the card reader 87, and the user inputs the personal identification number on the touch panel 19 to obtain the approval. When the approval is obtained, by performing a predetermined return operation on the touch panel 19, the solenoid 60 is driven and the lever 57 swings to the unlocked position, and the key holder 26 is directed to the predetermined lockable position in the insertion opening 56. Can be inserted. Note that other return operations are the same as in normal operation.

Next, a key exchange operation for exchanging the key 23 connected to the key holder 26 for another key 23 or adding another key 23 will be described.

The administrator who has the authority of the key exchange selects the key exchange in the main menu of FIG. 8(a) after the approval by inputting the card information and the personal identification number, and thereby the selection shown in FIG. 13(a). The screen is displayed. By selecting the selection button corresponding to the key holder 26 for performing the key exchange operation on the selection screen of FIG. 13A, the selected selection button is displayed in a display form different from that of the other selection buttons.

Further, the special operation door 13 is unlocked, the solenoid 74a of the special operation section 22 is driven, the stopper is retracted from the special operation insertion opening 70, and the key holder 26 can be inserted into the special operation section 22. Become.

The administrator removes the key holder 26 from the lock mechanism 25 whose display portion 66 lights up, shifts the removed key holder 26 into the special operation insertion opening 70 by shifting the cover 71 of the special operation portion 22. As shown in FIGS. 2(a)(b) and 2(c), when the key holder 26 is inserted into the special operation insertion opening 70, the release member 72 is inserted into the release openings 51 and 36, and The release member 72 contacts the protrusion 39 of each locking portion 37, and each locking portion 37 elastically deforms in the outer diameter direction. As a result, the claw portion 38 of each locking portion 37 is disengaged from the groove portion 45 of the mounting portion 31, and the coupling between the main body portion 30 and the mounting portion 31 is released. After that, as shown in FIG. 2D, the mounting portion 31 is pulled out from the main body portion 30. By removing the mounting portion 31 from the main body portion 30, the connecting groove 47 opening to the peripheral surface side of the mounting portion 31 is exposed. Therefore, as shown in FIG. 2(e), the ring 32 is attached to the opening side of the connecting groove 47. Can be removed from the mounting portion 31 by moving to.

As a result, the release member 72 comes off from the main body portion 30, so that each locking portion 37 elastically deformed by the release member 72 returns to the locked state in which the claw portion 38 engages the groove portion 45 of the mounting portion 31. Then, the main body portion 30 and the mounting portion 31 are coupled so as not to come off.

In addition, after removing the mounting portion 31 from the main body portion 30, the main body portion 30 may be pulled out from the special operation insertion opening 70, and the main body portion 30 and the mounting portion 31 may be coupled and operated outside the special operation portion 22.

Further, when the detection unit 75 detects that the key holder 26 has been inserted into the special operation insertion opening 70, a key exchange history including date and time, administrator information, key information, and the like is stored in the storage unit 88.

The key holder 26 after the key exchange is inserted into the original lock mechanism 25, and the detection unit 65 detects that the key holder 26 has been returned, whereby the key exchange is completed.

Note that the key extraction information, the history of key exchange information, and the like stored in the storage unit 88 can be printed out by the printer 21 by the operation of the administrator.

Next, FIG. 14 shows the key holder 26 of the second embodiment. The same components as those in the above-mentioned embodiment are designated by the same reference numerals and the description thereof will be omitted.

A female screw 91 is formed on the inner periphery of the mounting port 35 of the main body portion 30. The plurality of locking portions 37 are projected toward the release port 36 side or the mounting port 35 side and are projected toward the center of the main body portion 30.

In the mounting portion 31, a male screw 92 that is screwed into a female screw 91 is formed on the outer periphery of the insertion portion 42, and projections having a sawtooth cross section are radially provided on the end surface of the insertion portion 42 to form a latch portion 93. ..

A latch member 94 is arranged between the body portion 30 and the mounting portion 31. The latch member 94 is movable in the mounting port 35 in the axial direction, has a latch portion 95 that engages with the latch portion 93 of the mounting portion 31 on one end surface, and has a shaft portion 96 protruding from the other end surface. There is. On the peripheral surface of the shaft portion 96, a plurality of groove portions 97 that can be engaged with the locking portion 37 are formed along the axial direction. A spring 98 that presses the latch portion 95 of the latch member 94 against the latch portion 93 of the mounting portion 31 is arranged between the main body portion 30 and the latch member 94. The illustration of the erroneous insertion prevention unit 33 is omitted in FIG.

The relationship between the latch portion 93 of the mounting portion 31 and the latch portion 95 of the latch member 94 is configured as follows. Assuming that the rotation of the latch member 94 is restricted, when trying to rotate the mounting portion 31 in the rotation direction for mounting the mounting portion 31 on the main body portion 30, the latch portions 93 and 95 do not mesh with each other, and When the mounting portion 31 is rotated in the rotation direction for removing the mounting portion 31 from the main body portion 30, the latch portions 93 and 95 are engaged with each other, so that the rotation of the mounting portion 31 is restricted.

Then, as shown in FIG. 14A, in the assembled state of the key holder 26, the mounting portion 31 is screwed into the mounting opening 35 of the main body portion 30. The latch portion 95 of the latch member 94 pressed by the spring 98 meshes with the latch portion 93 of the mounting portion 31. Each locking portion 37 engages with each groove portion 97, and rotation of the latch member 94 is restricted with respect to the main body portion 30.

Therefore, even if an attempt is made to rotate the mounting portion 31 in the rotational direction in which the mounting portion 31 is removed from the main body portion 30, the mounting portion 31 that meshes with the latch member 94 whose rotation is restricted with respect to the main body portion 30 does not rotate. Therefore, the ring 32 to which the key 23 is connected does not come off from the mounting portion 31.

Further, at the time of key exchange, as shown in FIG. 14(b), by inserting the key holder 26 into the special operation part 22, the release member 72 is inserted into the release port 36, and the release member 72 is inserted into each locking part. Abutting on 37, each locking portion 37 elastically deforms in the outer diameter direction. As a result, each locking portion 37 is disengaged from the groove portion 97 of the shaft portion 96, and the latch member 94 can be rotated.

In this state, as shown in FIG. 14(c), by rotating the mounting portion 31 in the rotational direction away from the main body portion 30, the latch member 94 meshed with the mounting portion 31 can be rotated, The part 31 and the latch member 94 rotate together, and the mounting part 31 moves in the axial direction away from the main body part 30.

It can be removed from the groove 47.

On the other hand, after the ring 32 to which the key 23 to be exchanged is connected or the ring 32 to which another key 23 is added is attached to the mounting portion 31, the mounting portion 31 is pressed against the mounting opening 35 of the main body portion 30 in the mounting rotation direction. Rotate and screw it into the body 30.

While the mounting portion 31 is being screwed into the main body portion 30, the latch portion 93 of the mounting portion 31 abuts on the latch portion 95 of the latch member 94, but when the mounting portion 31 rotates in the mounting rotation direction, the latch portion 94 meshes with the latch member 94. Therefore, even if the rotation of the latch member 94 is restricted, the mounting portion 31 can be screwed into the main body portion 30. The latch member 94 is pushed into the main body portion 30 against the bias of the spring 98 while being pressed by the mounting portion 31.

When the edge portion 43 of the mounting portion 31 comes into contact with the body portion 30 and is tightened, the coupling is completed, and the key holder 26 is removed from the special operation portion 22. As a result, each locking portion 37 fits into the groove portion 97 of the shaft portion 96 and restricts the rotation of the latch member 94. Therefore, the main body portion 30 and the mounting portion 31 are in a coupled state in which they cannot be separated.

It should be noted that when the mounting portion 31 is disengaged from the main body portion 30, the main body portion 30 may be removed from the special operation portion 22 and the main body portion 30 and the mounting portion 31 may be coupled and operated outside the special operation portion 22.
