[0012]
The electric lock operating device 1 according to this embodiment includes an information reading unit that reads identification information for personal authentication, and an operation on the electric lock 9 by comparing the read identification information with previously stored personal authentication data. In the electric lock operating device 1, the operation device main body 2 including the electric lock control unit 4 that performs output includes a destruction detection unit that detects a destructive action such as disassembly into the operation device main body 2. A circuit for switching the connection to the second connection circuit 82 based on the detection output from the breakage detection unit, as well as the connection circuit 81 provided between the lock control unit 4 and the electric lock 9. A switching unit 7 is provided.
[0013]
Further, in the electric lock operating device 1 according to this embodiment, the circuit switching unit 7 is disposed outside the operating device main body 2.
[0014]
Specifically, the electric lock operating device 1 is installed at an entrance to an area such as a building where research and development requiring confidentiality is performed, and recorded on a magnetic card (not shown), for example. It is a card reader that reads identification information for personal authentication and locks and unlocks an electric lock provided at the entrance door. The operating device body 2 is connected to the electric lock 9 having a driving means for electrically driving a locking mechanism such as a geared motor or a solenoid inside via a circuit switching unit 7 provided in parallel with the electric lock 9. Connected and used.
[0015]
The operation device main body 2 includes a data reading unit 3 formed by a magnetic reading device serving as an information reading unit, a ROM 42, a RAM 43, and an electric lock that the data reading unit 3 receives as an input and controls the electric lock 9. The electric lock control part 4 which has CPU41 to which the electric lock control circuit 44 which performs control 9 is connected, the apparatus removal detection part 5 used as a destruction detection part, and the alarm buzzer 6 are comprised. . Between the electric lock control unit 4 and the circuit switching unit 7 provided between the electric lock control unit 4 and the electric lock 9, a connection circuit 81 and a second connection circuit 82 attached to the connection circuit 81 are provided. Provided.
[0016]
The operating device body 2 is screwed and fixed to remove the case cover (not shown) constituting the operating device body 2 so as to supply power to the operating device body 2, and will be described later. The connection electric wire which forms the connection circuit 81 with the electric lock 9 and the 2nd connection circuit 82 attached to the connection circuit 81 is connectable. In this case, the operation device main body 2 is provided with a device removal detection unit 5 formed by a micro switch or the like that closes in conjunction with the removal of the case cover.
[0017]
The electric lock control unit 4 includes a personal identification information data table for personal authentication, a ROM (read only memory) 42 as a storage means in which a processing program for comparing the personal identification information and controlling the electric lock 9 is stored, A RAM (Random Access Memory) 43 and an electric lock control circuit 44 for performing an electric lock operation output are connected to the CPU 41. The electric lock control unit 4 receives an identification information signal input from the data reading unit 3 based on magnetic information stored in a card and having a predetermined data configuration in a data table previously registered in the ROM 42 of the storage means. A lock signal is output to the electric lock control circuit 44 when there is a match with the information entered in the data table by collating with the personal identification information. The electric lock control circuit 44 controls the locking of the electric lock 9 by operating a solenoid 91 provided in the electric lock 9 from the electric lock control circuit 44. Further, in this case, the CPU 41 issues an alarm from the buzzer 6 when a contact signal is input from a micro switch of the device removal detection unit 5 described later.
[0018]
The device removal detection unit 5 can be formed by, for example, a microswitch having a two-pole contact circuit. In this case, one of the two-pole contact circuits has an output from the CPU 41 and the other has an output from the circuit switching unit 7 described later. The device removal detection unit 5 is attached to the inside of the operation device main body 2 so that a hinge serving as a contact driving unit of the microswitch is always pressed against the case cover. That is, in the normal use state of the electric lock operating device 1, each of the contact circuits is open, and the circuit is closed in conjunction with the removal of the case cover. It can be easily detected with a relatively simple configuration.
[0019]
The circuit switching unit 7 prevents the electric lock control circuit 44 from energizing the electric lock 9 from being unlocked due to a destructive action from the outside of the operating body 2 such as the removal of the case cover. For example, as shown in FIG. 2, a relay RY <b> 1 for controlling the electric lock 9 in the internal circuit of the circuit switching unit 7 is formed. The circuit switching unit 7 is provided outside the operation device main body 2, and the circuit switching unit 7 and the operation device main body 2 are attached to a connection circuit 81 and a connection circuit 81 serving as a DC driving power source for the electric lock 9. The circuit switching unit 7 and the electric lock 9 are connected and installed only by the connection circuit 81. The second connection circuit 82 is a power supply side wiring of the DC drive power supply. The circuit switching unit 7 is installed in the vicinity of the electric lock 9, but the connection circuit 81 and the second connection circuit 82 are protected against destruction of the connection circuit so that both the connection circuit 81 and the second connection circuit 82 are not disconnected at the same time. Thus, it is preferable that the circuit switching unit 7 is connected via different wiring installation paths.
[0020]
In the electric lock operating device 1 described above, in a normal use state, a DC driving power is applied to the solenoid 91 of the electric lock 9 through the wiring path on the connection circuit 81 side by the electric lock control circuit 44 of the operating device body 2. The lock is controlled. When there is a destructive action such as removal or disassembly of the case cover of the operation device main body 2, first, this destructive action is detected by the device removal detecting unit 5. The device removal detection unit 5 sounds an alarm buzzer 108 provided inside and outputs a signal to the circuit switching unit 7. Then, the circuit switching unit 7 outputs an operation so that the connection by the connection circuit 81 between the electric lock control unit 4 and the electric lock 9 is switched to the second connection circuit 82 provided therebetween. In other words, when there is a destructive action on the electric lock operating device 1 from the outside, the time for the electric lock 9 to be unlocked is delayed, and the act of easily unlocking the electric lock 9 to prevent intrusion is prevented. The improvement can be realized.
[0021]
In this case, the circuit switching unit 7 disposed outside the operation device main body 2 switches to the second connection circuit 82 provided between the electric lock control unit 4 and the electric lock 9. The circuit switching unit 7 controls the electric lock 9. That is, even if the wiring connection of the connection circuit 81 is disconnected from the operation device main body 2, the electric lock 9 is controlled in the circuit switching unit 7, and energization of the electric lock 9 is continued and the control is also affected. No.
[0022]
Therefore, according to the electric lock operating device 1 described above, a destructive action such as disassembly into the operating device main body 2 is detected by the device removal detection unit 5, and the device switching detection unit 5 sends the electric lock to the circuit switching unit 7. Since the operation output is performed so as to switch the connection between the control unit 4 and the electric lock 9 to the second connection circuit 82 provided therebetween, even if the operation device main body 2 is destroyed, the operation device main body 2 Destruction detection can be performed and the electric lock 9 can be kept locked.
[0023]
Then, in the circuit switching unit 7 disposed outside the operation device body 2, switching to the second connection circuit 82 provided between the electric lock control unit 4 and the electric lock 9 is performed. The second connection circuit 82 can be made difficult to be confirmed by the vandal, so that the unlocking of the electric lock 9 by the vandal can be further delayed.
[0024]
In the present invention, in addition to the above-described ones, for example, as shown in FIG. 3, a circuit switching unit 7 is disposed inside the operation device main body 2, and the electric lock control unit 4 and the electric lock 9 are connected. The second connection circuit 82 provided between them is connected to the connection circuit 81 near the electric lock 9, or the second connection circuit 82 is arranged by providing one or more multiple wiring paths, etc. Includes various embodiments.
[0025]

Since the operation output is made to switch the connection between the electric lock control unit and the electric lock to the second connection circuit provided between the electric lock control unit and the electric lock from the unit to the circuit switching unit, In addition, it is possible to continue to lock the electric lock by detecting the destruction of the operating body.
[0026]
Further, in the electric lock operating device according to claim 2, the second connection provided between the electric lock control unit and the electric lock at the circuit switching unit disposed outside the operation device main body. Since the switching to the circuit is performed, the second connecting circuit can be hardly confirmed by the vandal, so that the unlocking of the electric lock by the vandal can be further delayed.
