[Embodiment 1! 111] An apparatus according to an embodiment of the present invention will be described below based on the drawings. 1 to 5 show the device of the first embodiment, in which FIG. 1 is a perspective view thereof, FIG. 2 is a sectional view taken along the line ■-■ in FIG. Figure 1 is a cross-sectional view along the ■-■ line, Figure 4 is the 3rd
Part of the diagram is detailed, Figure 5 is a professional diagram showing the electrical configuration, and Figure 6 is a flowchart showing the control operation! 〉ru. The key storage device a is shaped like a rectangular parallelepiped, and has a key extraction portion a1 in its front half and a key storage portion a2 in its rear half. In the front of the key extraction part a1, there is a swing door 1, and on the left side of this door I there is a key card C.
A blue LED (2) and a red LED (2) are provided to indicate the operating status of the system of the key storage device a. A well-known electric lock 3 is incorporated into the door 1. When the electric lock 3 is unlocked, rotate the lever handle 4 in the direction of the arrow to move the launch head 5 back and open the door 1.
It is configured so that it can be opened. Inside the insertion slot 2, a well-known card reader mechanism (not shown) and a controller 6 that collectively controls the key storage device a are provided. The depth of the key take-out portion a1 is tapered as shown in FIG. 2, and a key take-out lower is provided in the inner part of the key take-out portion a1 with an opening having an area from which one key K can be taken out. Note that 8 in the figure is a space in which the controller 6 is housed. As shown in FIG.
and a motor M (rotating means) for rotationally driving this rotary body 9, and the outside, which is communicated with the key extraction part a1 via the key extraction lower, is cut off from the outside. . In addition to the above-mentioned motor, a combination of a solenoid and a ratchet can be used as the rotating means. The rotating body 9 has a cylindrical shape, and has a large number (plurality) of key holding parts 10.10 each consisting of hooks for hanging keys K on its outer peripheral wall.
... are provided at a predetermined interval, that is, the two key holding portions 1o are provided at an interval such that the two key holding portions 1o are not located in the key extraction lower portion at the same time. Note that although this rotating body 9 is rotated by the motor M, care is taken so that this rotating body 9 itself is not forced to rotate. Such a reversal prevention mechanism can be achieved by a deceleration mechanism that decelerates the rotation of the motor M using a combination of a worm and a worm gear. As shown in FIG. 4, the key holder 10 is provided with key detecting means 8 consisting of a microswitch S that is activated when a key K is hung on a hook. Therefore 5
By using the detection signal from this key detection means, for example, the central control room can detect the usage status of the room with the key, and when it is detected that the key is being held, the power supply of the room can be switched off. It can be used as a secondary leg signal to turn off the waste. As the key detection means, in addition to the above-mentioned microswitch S, a device using a photoelectric element or the like can be adopted. The electrical configuration of the key storage device a, that is, the electrical configuration of the locking device 6 is shown in FIG. This control unit 6 is a central processing unit (CP) that performs calculation using the system program stored in the ROM 20 and the tooling program stored in the RAM 21.
U) It is composed mainly of 22. This CPU 22 includes a read driver 24 for the magnetic head H via the unit 23, and an LE that controls the lighting of the LEDs 2 and 3.
A D driver 25, a lock driver 26 that drives and controls the electric lock 3, and a motor driver 27 that drives and controls the motor M are connected. Note that the solenoid driver 28 is used when the rotating body 9 is a rotating body shown in FIG. 9, which will be described later. The control operation of the key storage device a having the above configuration will be explained using the flowchart shown in FIG. Now, in the key storage device a, a plurality of keys K are held in advance in the key holding part 10, and the RAM 2 of the controller 6
It is assumed that data corresponding to each key K is stored in advance in the key K1 (or the ROM 20). And LED■
It is assumed that is lit and the key storage device a is operating normally (step 100 is determined; hereinafter, step is referred to as S). At this time, when the key card C is inserted into the insertion slot 2 and the data is read from the key card C to the magnetic field with the magnetic field H, -
L E D (D is layered and the key card C insertion stand is notified that the electric lock 3 is preparing to be unlocked, and is rotated via the motor M or motor driver 27, and the key card The key K corresponding to the data of C is located in the key extraction lower part (S102 affirmative, 5104.5
106 affirmative, 5108.5ilo). In addition, if the data of the inserted key card C is incompletely read or if a card of another system is inserted (No in S106), the LED ■ or a timer (not shown) lights up for a predetermined period of time, indicating that the inserted key card C is not fully read. It is notified that the electric lock 3 can only be unlocked with the card (S112.5114). Now, when the rotation of the motor M is finished and the predetermined key K is located in the key extraction lower part (3110 affirmative), the lock driver 27
activates the solenoid (not shown) of the electric lock 3, allowing the lever handle 4 to rotate, thereby allowing the door 1 to be opened (3116, 5l18). In the meantime, the person inserting the key card C can open the door 1 and take out the key K held by the rotating body 9 from the key take-out lower, and after taking out the key K, the door 1 will open. When closed, the electric lock 3 is locked again (S12
0). This locking ends the series of key extraction operations (3122 affirmative). The electric lock 3 can be locked by inserting the 31201 key card C into the insertion slot 2 again, or by providing a separate lock switch,
The configuration can be simplified by locking the door by detecting the closed state of the door. Therefore, although not shown in the drawings, this embodiment is provided with a door sensor for detecting the opening and closing of the door 1, and is configured such that a detection signal from this is sent to the CPU 22 via the I10 unit 23. moreover,
This door sensor may be used to prevent the door 1 from being forgotten to close. For example, is it possible to close door 1 after taking out key K?
If the door is left open for more than a predetermined period of time, an alarm will be issued to prevent the door from being forgotten. To store the used key K in the key storage device a again, the key card C can be inserted into the insertion slot 2 and the door 1 opened, as described above. Further, when the key storage device a is first started to be used, the data of each issued key card C is registered in the RAM 21. This registration is performed by turning on the registration setting mode key (not shown) and setting the controller 6 to the registration mode, and then each key card C.
This is done by inserting the In addition, if the key requires extremely high security, the fji key must be stored in the ROM 20 in advance so that only an external key can be registered.
You can also leave it there. As described above, the device of this embodiment uses the key card C to unlock the electric lock 3 and open the door 1, and to take out a predetermined key from the key holding part a2 or to insert a given key into the key holding part a2. Since the key can be stored in the same key, the device can be made smaller and costs can be reduced. FIG. 7 shows another example of a rotating body, and the rotating body 9' shown here has its rotation axis oriented in the horizontal direction, whereas the rotating body 9 described above has its rotation axis in the contraction direction. It is provided. The key holding portion 10' of the rotating body 9' is configured such that the key K is inserted into a split pin 30, as shown in FIG. 8, in order to prevent the key from falling due to the rotation of the rotating body 9'. In addition, four parts 31 are provided to facilitate key removal. The rotating body 9'' shown in FIG. 9 further shows an example of a pond, and has a configuration in which three rotating bodies 9' shown in FIG. P2 are arranged in parallel. This rotary body 9'' can triple the number of key storage portions 10' compared to the aforementioned rotary body. In this rotary body 9'', in order to locate the key storage portions 10' of each row in the key extraction lower, the rotary shaft 32 is provided with a vertical shaft, and the shaft center of the rotary body 9'' corresponds to the shaft. A hole with roughness is provided. Therefore, the rotating body 9'' is rotated by the rotating shaft 32, and the rotating body 9'' is rotated by the rotating shaft 32.
It is configured to be movable in the direction of the axis of the second axis. This movement of the rotating body 9'' in the axial direction is performed by a solenoid S driven and controlled by a 5-solenoid driver 28. That is, a roller 34 provided at the tip of a rod 33 of the solenoid S moves the rotating body 9'' It is inserted into a hole 36 of a drive wheel 35 that is integrally provided at one end.
Therefore, when the rod 33 is moved in the direction of the arrow, the rotating body 9'' is also moved in the axial direction.The rotating body 9'' has three rows of key storage sections or two.
It is possible to have two or four or more rows. Furthermore, as an example of a pond in a rotating body, in addition to the above-mentioned cylindrical pond,
It can also be a belt conveyor type. Further, in the above embodiment, the key card C is used to input data, but it may also be input using a numeric keypad, or a well-known input means that can identify an individual such as a fingerprint or retina may be used. You may also do so. Furthermore, although the electric lock 3 is provided on the door 1, it goes without saying that it may be provided on the door frame side. [Effects of the Invention] The device of the present invention has a single door in the key extraction portion that can be opened when the electric lock is unlocked, and the key storage portion has a number of key storage portions in the rotating body. Since the key storage section is positioned at the key extraction port of the key extraction section in accordance with the input data, the device can be made smaller and the installation space can be reduced. Another advantage is that since the electric lock is single, it can be manufactured at low cost. In addition, when a key detection means is provided in the key holder, the detection signal from the detection means can be used to determine the usage status of the room for that key, or to control the supply of power and waste. becomes possible.
