[0011]

[Embodiment of the invention]

 An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a perspective view of an electronic device housing rack 1 according to the present embodiment, and FIG. 2 is a front view of the electronic device housing rack 1. The rack 1 for accommodating electronic equipment has a rectangular parallelepiped shape. In the center of the left end of the door 3, a handle 4 for opening and closing the door 3 is provided. A first lock device 5 is provided on the handle 4 of the door 3, and a second lock device 6 is provided on the upper portion of the handle 4 independently. Further, between the first lock device 5 and the second lock device 6, a release device 7 used when the second lock device 6 cannot be used is provided.

FIG. 3 is an enlarged view of the first lock device 5 and the key 8. FIG. 4 is a diagram showing a state where the key 8 is inserted into the first lock device 5. The first lock device 5 locks by inserting the insertion portion 8a of the key 8, and has a keyhole 9 that matches the shape of the insertion portion 8a of the key 8. The key 8 is stored in a storage location (not shown).

FIG. 5 is an enlarged view of the second lock device 6. The second lock device 6 locks the door 3 by inputting a password, and a battery is used as a power supply. At the center of the second lock device 6, a ten key 30 for inputting is provided. The numeric keypad 30 is composed of input buttons 10 to 19 for inputting a personal identification number on which numbers 0 to 9 are printed, and a lock button 20 on which an English letter L is printed. They are arranged at intervals. The PIN can be set and changed to any two types of 4 digits or 1 to 8 digits.

FIG. 6 is a block diagram of the second lock device 6. The second lock device 6 is configured around the CPU 21. The CPU 21 is connected to a ROM 22 in which a processing procedure is stored, and a RAM 23 for storing data being processed. The CPU 21 is connected to a numeric keypad 30 and an opening switch 24 that is turned on when the door is opened. Further, an unlocking / locking mechanism 25 for unlocking and locking is connected to the CPU.

In such a configuration, when locking the door 3, first, the key 8 is removed from the storage location, and the key 8 is inserted into the key hole 9 in the first lock device 5 provided on the handle 4 of the door 3. 8 is inserted and locked. Next, in the second lock device 6 provided above the handle 4 of the door 3, for example, when the password is set to “1234”, the input is performed by sequentially pressing the input buttons 11, 12, 13, and 14. Thereafter, the lock button 20 is depressed to lock by the unlocking mechanism 25. Thus, the door 3 can be locked by both the first lock device 5 and the second lock device 6.

When unlocking the door 3, the insertion portion 8 a of the key 8 is inserted into the keyhole 9 of the first lock device 5 and unlocked. Next, the input buttons 11, 12, 13, 14 of the second lock device 6 are sequentially pressed to input and unlocked by the unlocking mechanism 25. Thus, the door 3 can be opened by unlocking the door 3 with the first lock device 5 and the second lock device 6.

In the present embodiment, the door 3 is unlocked by the first lock device 5 and the second lock device 6. Therefore, even if one of the first lock device 5 and the second lock device 6 is unlocked, the door 3 is locked by the other, so the first lock unlocked by the key 8. As compared with the case where the door 3 is locked only by the device 5, the security of the housed electronic device can be enhanced.

The password used for the second lock device 6 may be stored by the person who manages the electronic equipment rack 1, and the password for the key 8 used by the first lock device 5 may be stored. There is no risk of loss as in the case. Therefore, security can be further enhanced when the first lock device 5 and the second lock device 6 are provided, respectively, than when two first lock devices 5 are provided on the door 3. Further, compared to the case where two second lock devices 6 are provided, security can be sufficiently improved without increasing the cost.

In addition, since the second lock device 6 uses a battery as a power supply, the second lock device 6 does not need to be affected by an external power supply. Then, when the battery runs out and the input of the personal identification number becomes impossible, the locked state by the second lock device 6 can be released by using the release device 7. Therefore, even if the battery runs out, the door 3 can be opened.

On the other hand, FIG. 7 is a flowchart showing an automatic locking process of the second lock device 6. In this automatic locking process, the input buttons 11, 12, 13, and 14 are sequentially pressed to input a password. This is a subroutine called from the main routine when the door 3 is unlocked by the unlocking mechanism 25. When this automatic locking process is called, a timer is started first (S1). Next, it is determined whether or not the door 3 is opened by an ON input of the door opening switch 24 (S2). If the door 3 has not been opened, it is determined whether or not the timer has elapsed for 10 seconds (S3), and steps S2 and S3 are repeated until 10 seconds have elapsed. On the other hand, when 10 seconds have elapsed, the door 3 is locked by the unlocking mechanism 25 (S4). If the result of the determination in step S2 indicates that the door 3 is open, the process returns to the main routine without performing the locking process.

Accordingly, when the door 3 is unlocked by the second lock device 6 by mistake, there is no need to input the password again to lock the door 3, so that the operation of the second lock device 6 becomes more effective. Can be done efficiently.

In the present embodiment, the first lock device 5 is provided on the handle 4 and the second lock device 6 is provided independently above the handle 4. If possible, the same effect can be obtained regardless of where the door 3 is provided independently. For example, the second lock device 6 is provided on the handle 4 and the first lock device is provided above the handle 4. The lock devices 5 may be provided independently.

[0024]

[Effect of the invention]

 As described above, in the invention of claim 1, the door is unlocked by the first locking device and the second locking device. For this reason, even if either the first lock device or the second lock device is unlocked, the door is locked on the other side. The security of the electronic equipment to be housed can be increased as compared with.

Further, the management of the key used in the first lock device is managed in a separate storage place, and the personal identification number used in the second lock device is managed by a person managing the electronic equipment rack. It was made to manage by setting and storing a password. Therefore, there is no possibility that the password is lost as in the case of the key. Therefore, the security can be further enhanced when the first lock device and the second lock device are respectively provided than when the two first lock devices are provided on the door. Further, compared to the case where two second lock devices are provided, the security can be sufficiently increased without increasing the cost.

According to the second aspect of the invention, when the door is accidentally unlocked by the second lock device, it is not necessary to input the password again to lock the door. The operation of the locking device can be performed more efficiently.
