Embodiment An embodiment of a lock device with a camera according to the present invention will be described below with reference to FIGS.

First, FIGS. 1 and 2 show a basic configuration of a locking device with a camera according to the present invention. The lock device 1 with a camera
It has a cylinder lock device 2, an operation detection device 3 provided in the cylinder lock device 2, and a camera operation circuit 5 that generates a signal for operating the camera device 4 based on the output of the operation detection device 3.

As shown in FIG. 2, the operation detection device 3 is a key detection switch 6 for detecting insertion of a key into the cylinder lock device 2 or a rotation detection switch 8 for detecting rotation of a key cylinder 7 provided in the cylinder lock device 2. Having. Key cylinder 7
Dog 7a that moves in the radial direction when the key is inserted,
There is provided a lever 7b which rotates by the movement of the dog 7a. The movable piece (not shown) of the key detection switch 6 is biased in one direction by a spring, and the lever 7b is also biased in one direction by the spring. The key detection switch 6 is turned on by turning the lever 7b.
Controlled off. A lever 9 operatively connected to a lock mechanism (not shown) is attached to an end of the key cylinder 7. The lever 9 rotates together with the key cylinder 7 to operate the rotation detection switch 8.

For example, the camera operation circuit 5 is constituted by an IC such as a one-chip microcomputer and operates according to the operation sequence shown in FIG.

From the start 110, the camera operation circuit 5 determines whether or not a key has been inserted based on the output of the key detection switch 6 (step 111). When the key is inserted, the camera operation circuit 5
Is operated (step 112), and subsequently, it is determined whether or not the key cylinder 7 has been rotated by the output of the rotation detection switch 8 (step 113). When the cylinder lock device 2 is unlocked using a regular key, the key cylinder 7 is rotated after a short time has elapsed after the key detection switch 6 has been activated, and the rotation detection switch 8 has been activated. When the rotation detection switch 8 is actuated, an output is generated from the camera operation circuit 5 by the output of the rotation detection switch 8 to determine the unlocking person, and the camera device 4 is operated for a certain period of time to photograph the user. be able to.

A key detection switch 6 attached to the cylinder lock device 2 as the operation detection device 3 detects insertion of a tool. When the key cylinder 7 is not rotated in step 113, the process proceeds to step 115, and it is determined whether or not the timer has counted a predetermined time. When the cylinder lock device 2 is unlocked illegally, a tool is inserted into the cylinder lock device 2. When a regular key is used, the cylinder lock device 2 is unlocked in a short time, whereas in a picking operation for illegal unlocking, after inserting a tool into the cylinder lock device 2, it takes a considerable time to unlock. Need. That is, the time from when the key detection switch 6 is turned on to when the rotation detection switch 8 is operated requires twice or more times as long as the normal unlocking. Therefore, if the time from when the tool is inserted into the cylinder lock device 2 until the rotation detection sensor is unlocked and the rotation detection sensor is operated is longer than the time set by the timer in the camera operation circuit 5, it is determined that the lock is illegally unlocked. I do. When the timer has counted a predetermined time, it is determined that the lock has been unlocked, and the camera device 4 is operated in step 114. If the predetermined time has not elapsed in step 115, the process returns to step 113 to determine whether or not the key cylinder 7 has been rotated.

FIG. 5 shows an example in which the camera operation circuit 5 is constituted by a discrete circuit. When the key detection switch 6 is turned on, the timer 5a is operated, and the one-shot multivibrator 5b
Generates a pulse in the OR gate 5d when the output of the timer 5a falls. The output of the rotation detection switch 8 activates the one-shot multivibrator 5c, and the pulse of the one-shot multivibrator 5c is applied to the clear terminal of the timer 5a and the OR gate 5d. When the OR gate 5d generates an output, the one-shot multivibrator 5e generates a pulse and turns on the transistor 10 to drive the camera device 4 for a certain time.

FIG. 6 shows a keyless entry device as an embodiment of a lock device with a camera. The keyless entry device includes an input device having a plurality of push switches 11, a camera operation circuit 5 having an input terminal connected to the input device, a lock driving device 43 and a camera connected to output terminals of the camera operation circuit 5. Device 4.

The camera operation circuit 5 operates according to the operation sequence shown in FIG. First, the process proceeds from the start of step 120 to step 121 to determine whether any one of the push switches 11 has been operated. If none of the push switches 11 is operated, the process remains at step 121. Push switch 11
When either of them is operated, the process proceeds to step 122, where it is determined whether or not a coincidence signal for operating the lock driving device 43 is generated by pressing the plurality of push switches 11 in a predetermined order.
When the coincidence signal is generated, the camera device 4 is operated. If the lock driving device 43 is not operated in step 122, the number of times the push switch 11 has been tampered with is detected (step 123). When the number of mischiefs has not reached the predetermined number, the process returns to step 121, and when the number has reached the predetermined number, the camera device 4 is operated.

FIG. 8 shows an example in which the keyless entry device is constituted by a discrete circuit. This keyless entry device has a plurality of switches 11 on which numerals 0 to 9 are displayed as input devices.
Having. Multiple switches 11 prevent chattering
The BCD (binary coded decimal) conversion circuit 12 is connected to a comparator 25 as comparison means and an OR gate 13. The output of the OR gate 13 is supplied to an address counter 23 and also to a buzzer 14 and a retrigger one-shot multivibrator 19 via a one-shot multivibrator 18. The retrigger one-shot multivibrator 19 is connected to the light emitting element 15 and the one-shot multivibrator 20. The buzzer 14 is activated by the output of the OR gate 13 generated each time the switch 11 is pressed, and generates an auditory signal. The light emitting element 15 is turned on by the output of the retrigger one-shot multivibrator 19 to indicate the operation of the retrigger one-shot multivibrator 19.
When receiving a signal from the one-shot multivibrator 18, the retrigger one-shot multivibrator 19
An output having a pulse width of seconds is generated, and when the next input is received within 5 seconds, counting of the pulse width is started again from that point. When the output of the retrigger one-shot multivibrator 19 stops, the one-shot multivibrator 20 generates an output at the falling edge of the pulse and gives a clear signal to the address counter 23 through the OR gates 21 and 38. The address counter 23 counts the number of outputs of the one-shot multivibrator 18 and generates an address signal for each digit. The address signal of the address counter 23 is given to a storage 24 as storage means. The output terminal of the storage device 24 is connected to the comparator 25. The one-shot multivibrator 18 is connected via a delay circuit 16 to one input terminal of an AND gate 17, and the output terminal of the AND gate 17 is connected via OR gates 21 and 38 to a clear terminal of an address counter 23.

The output terminal of the comparator 25 is connected to the counter 26. The output terminal of the counter 26 is connected to the flip-flop 41.
The Q output terminal and the Q bar output terminal of the flip-flop 41 are connected to an actuator 43 such as a motor. The flip-flop 41 generates an output from the Q output terminal when the output of the counter 26 is first received to operate the actuator 43 in the locked state, and outputs the signal from the Q bar output terminal when the output of the counter 26 is received next. The actuator 43
Is operated in the unlocked state.

The lock device 30 attached to the door includes a dead bolt 35 movably arranged in the length direction and a dead bolt 35
And a latch bolt 37 arranged so as to be able to move in the length direction substantially in parallel with the latch bolt 37. Dead bolt 35 and latch bolt 37
Are engageable with holes 32 and 33 of striker 34 mounted on wall 31, respectively. As is known, the latch bolt 37
Is urged by a spring 36 in the protruding direction. Lever 9
An intermediate member 51 constituted by a swing lever with a play angle is rotatably attached to the rotary shaft 50. The intermediate member 51 has a substantially sector shape, and has bent portions 51a formed on both sides thereof so as to be in contact with the side portions of the lever 9, respectively. The switch 8 is fixed adjacent to the intermediate member 51. The tip of the lever 9 engages with the notch 35a of the dead bolt 35. A key inserted into a key cylinder (not shown) can be removed from the key cylinder when the lever is brought to a substantially vertical state in FIG. 8 by rotating the key cylinder to the neutral position. When the key is inserted into the key cylinder at the neutral position and rotated in the unlocking direction, the lever 9 comes into contact with the inclined surface 35b constituting the notch 35a of the deadbolt 35 as shown. Conversely, when the key is rotated in the locking direction, the lever 9 comes into contact with the inclined surface 35c constituting the cutout portion 35a of the dead bolt 35, and the tip of the dead bolt 35 can be inserted into the hole 32. At this time, the intermediate member 51 is rotated counterclockwise, and the switch 8 is turned off. Two notches 53 and 54 are formed on the outer periphery of the intermediate member 51, and the ball 56 is pressed against the notches 53 or 54 by the spring 55 to hold the intermediate member 51 in the unlocked position or the locked position. I do.

The output of the counter 26 is connected to the timer 44 through the OR gate 29, and the output of the timer 44 is sent to the camera device 4. The output of the AND gate 17 is a counter that counts the number of mismatches and generates an output when the count reaches a predetermined count value.
Granted to 27. The output of the counter 27 is connected to the timer 44 via the OR gate 29, and the output of the timer 44 is sent to the camera device 4. The output of the counter 27 is connected to a timer 28 that generates an output for holding the conversion circuit 12 as an input device in a non-operating state (standby state) for a certain period of time.

In the above configuration, when the switch 11 is operated in a predetermined order and the input code signal is given to the comparator 25, the comparator 25 compares the input signal with the code signal stored in the storage unit 24, When they match, a match signal is given to the counter 26. In this case, if the code signal input from the switch 11 does not match the code signal stored in the storage unit 24, the output signal is not generated from the comparator 25, regardless of the operation of any one of the switches 11. Therefore, an invalid signal is generated from the AND gate 17, and the address counter 23 is cleared. However, when the code signal input from the switch 11 and all the code signals stored in the memory 24 match each other, the counter 26 generates an output and changes the Q output terminal of the flip-flop 41 from a low level to a high level. Switch to For this reason, the actuator 43 is operated, the deadbolt 35 is moved rightward, and the lock device 30 is switched to the unlocked state shown in the figure. Next, when an output is generated from the counter 26, the Q bar output terminal of the flip-flop 41 switches from a low level to a high level. Therefore, the dead bolt is
35 moves to the left locking position and switches the locking device 30 to the locked state. In this case, the intermediate member 51 has been moved to the unlocked position shown by the key, and the lever 9 is at the neutral position.

Next, when the key is inserted into a key cylinder (not shown) and rotated in the unlocking direction, the lever 9 is turned on the inclined surface 3 of the notch 35a.
5b, the dead bolt 35 is moved to the unlocked position shown. Next, when the key is rotated in the locking direction, the lever 9 is rotated.
Abuts against the inclined surface 35c of the notch 35a to move the dead bolt 35 to the locking position.

In the present embodiment, the OR gate 29 is
, The camera device 4 is operated for a certain period of time. When the number of mismatches is counted and reaches a predetermined count value, the output of the counter 27 causes the camera device 4 to operate for a certain period of time. At the same time, the timer 28 is operated by the output of the counter 27, and the conversion circuit 12 is kept in a non-operating state (standby state) for a certain time.

As described above, in the keyless entry device including the input device including the plurality of push switches 11, the camera device 4 is operated by the output of the comparison means or the output of the counter. The counter generates an output for operating the camera device 4 or an output for stopping the function of the input device for a predetermined time when a correct code signal is not input more than a predetermined number of times.

Further, FIG. 4 shows a locking device with a camera operated by remote control using electromagnetic waves. In the example shown in FIG. 4, the same parts as those shown in FIG. 3 are denoted by the same reference numerals, and description thereof will be omitted.

In this embodiment, other electromagnetic waves than infrared rays can be used.

When the input device 61 receives an electromagnetic wave including a predetermined code signal, the comparator 25 generates an output as an unlock signal. Thereby, the camera device 4 is driven. Conversely, input devices
A counter 27 is provided which counts the number of mismatches and generates an output for activating the camera device 4 when a predetermined count value is reached when the output of the comparator 25 is not generated when the electromagnetic wave is received a plurality of times by the 61. Can be In an electronic lock device using an electromagnetic wave, an electromagnetic wave including a code signal is received from an input device 61 provided with a reception sensor 60, and the counter 27 outputs the output of the comparator 25 when the input device 61 receives the electromagnetic wave a plurality of times. When this does not occur, the camera device 4 is operated when the number of mismatches is counted and reaches a predetermined count value.

The above embodiment of the present invention can be variously modified.
Although not shown in detail, for example, a lock device, a tamper switch that detects removal of the lock device, and a camera device 4 that is operated for a predetermined time when the tamper switch is operated are provided to detect the removal of the lock device. When a tamper switch is provided, the camera device 4 may be operated for a certain period of time when the tamper switch is operated.
