DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. 1 to 3.

As shown in FIG. 1, the operation control device according to the present invention includes a plurality of switches 11 constituted by a keyboard, a setting switch 8, and mode change switches 65, 68, and 74.
The operation control circuit 1 has an input terminal to which is connected, a driven device 2 constituted by an actuator such as a solenoid or a motor that operates a locking device, an output terminal to which a display device 3 and a buzzer 14 are connected. The operation control circuit 1 is constituted by an IC such as a one-chip microcomputer, and is programmed to operate according to the operation sequence shown in FIG. Although not shown, the operation control circuit 1 includes a first storage circuit that stores a code code, a second storage circuit that stores the first code code in a rewritable manner, and input signals from a plurality of switches 11. a first comparison circuit that compares the code code stored in the first storage circuit with the first code code stored in the first storage circuit and generates a match signal when they match; and a code input from the plurality of switches 11; a second comparison circuit that compares the code and a second code stored in the second storage circuit and generates a match signal when they match, and a first comparison circuit that generates a match signal; a timer that is activated for a certain period of time when a By operating the change switch 68, a time setting circuit for inputting a time to control the second memory circuit and a number of times set by a number of times setting circuit can be input, and when a second comparison circuit generates a predetermined number of match signals. It has a counter that switches the second memory circuit to standby mode, a clock circuit, and a comparison circuit that operates the second memory circuit only within the time set by the time setting circuit.

In FIG. 2, first, step 1. From the start of OO, the operation control circuit 1 proceeds to step 101 and determines whether or not a plurality of switches 11 have been operated. When there is an input from the keyboard, the process proceeds to step 102, and when the code code signals input from the plurality of switches 11 match the second code code stored in the second storage circuit, 2- The count of the rear down counter increases progressively.

Next, the process proceeds to step 104, where it is determined whether the count number of the counter is greater than a set value. When the count value of the counter is /JX less than the set value, the second comparator circuit generates a match signal in step 1.5.

Driven device 2 is actuated by this coincidence signal.

If the count value of the counter is greater than the set value in step 104, the second storage circuit is switched to a standby state in step 106. Therefore, the second sign code stored in the second storage circuit cannot then be read into the second comparison circuit.

If there is no keyboard input in step 101, the process proceeds to step 107, where it is determined whether the setting switch 8 has been turned on. When the setting switch 8 is turned on, a timer is activated (step 108), and it is determined whether there is any keyboard input (step 109). Step 109
If there is no keyboard input, the process proceeds to step 114, where it is determined by the count of the timer whether a certain period of time has elapsed. If the predetermined time has not elapsed in step 114, the process returns to step 109, and after the predetermined time has elapsed, the process returns to step 101.

If there is a keyboard input in step 109, the process proceeds to step 110, where the code code input from the keyboard is stored in the second storage circuit as a password. The process then proceeds to step 111 where the timer is started again and the process proceeds to step 112.

In step 112, it is determined whether or not there is a keyboard input. If there is a keyboard input, in step 113, the number of unlock permissions is set in the number of times setting circuit. When there is no keyboard input in step 112, step 1
The process proceeds to step 15, where it is determined whether or not the set time has elapsed. If the set time has not elapsed, the process returns to step 112, and when the set time has elapsed, the process returns to step 101.

The above embodiments of the invention can be modified. For example, the operation control circuit 1 described above can be constructed from a discrete circuit.

FIG. 3 shows an example in which a keyless engine 1--return device is constructed from a discreet 1--circuit.

This keyless entry device has a plurality of switches 11 on which numbers 0 to 9 are displayed. The plurality of switches 11 are connected to a first comparison circuit 25 and the OR games 1 to 13 via a BCD (pinary coded decimal) conversion circuit 12 that prevents chattering. The first comparison circuit 25 constitutes a first main control device. The output of the OR gate 13 is sent to the buzzer 1 via the one-shot multivibrator 18.
4. Retrigger is supplied to the multivibrator 19 and address counter 23. The one-shot multivibrator 19 is connected to the light emitting element 15 and the one-shot multivibrator 20 . The buzzer 14 is an OR gate 13 which is generated every time the switch 11 is suppressed.
is energized by the output of , and generates an auditory signal. Light emitting element 15 is from January to Riga one-shot multivibrator 19
The light is turned on by the output of the retrigger one-shot multivibrator 19 to indicate the operation. When one shot = 15, the retrigger trigger one shot 1 to multivibrator 19 generate an output with a pulse width of approximately 5 seconds, and when the next input is received within 5 seconds, the pulse width is counted again from that point onwards. Start. The one-shot multivibrator 20 generates an output at the falling edge of the pulse when the outputs of the retrigger 1 to retrig one-shot multivibrator 19 stop, and provides a clear signal to the address counter 23 through OR gates 21 and 22. Address counter 23 is one-shot multivibrator 1
The number of outputs of 8 is counted to generate an address signal for each digit.

The address signal of the address counter 23 is applied to the first storage circuit 24. An output terminal of the first storage circuit 24 is connected to a first comparison circuit 25. The one-shot multivibrator 18 is connected to the AND gate 1 via the delay circuit 16.
The output terminal of AND gate 17 is connected to the clear terminal of address counter 23 via OR gates 21 and 22.

Further, the output of the BCD conversion circuit 12 is stored in the second memory 6- The signal is sent to the circuit 60 and the second comparison circuit 61.

The second comparison circuit 61 compares the code sent from the plurality of switches 11 with the code stored in the second storage circuit 60, and when they match, the counter 6
2 produces an output. When all the digits of the code match, the counter 62 generates an output, energizes the flip-flop 41 through the OR gate 40, and operates the actuator 43 forming the driven device 2 (FIG. 1). Further, the output of the counter 62 is given to an up/down counter 76,
The up/down counter 76 is counted down. The second storage circuit 60 and the second comparison circuit 61 constitute an auxiliary operation control device.

The output terminal of the first comparison circuit 25 is connected to a counter 26 and an OR gate 28. OR gate 28 is connected to AND gate 17. The output terminal of the counter 26 is connected to a flip-flop 41 via an OR gate 40. The Ω output terminal and the Ω output terminal of the flip-flop 41 are connected to an actuator 43 such as a motor. For example, when the flip-flop 41 first receives the output of the counter 26, it generates an output from the Ω output terminal to operate the actuator 43 in the locked state, and then when it receives the output of the counter 26, it generates an output from the Ω output terminal. is generated to operate the actuator 43 to the locked state.

The locking device 30 attached to the door includes a deadbolt 35 disposed so as to be movable in the length direction, and a deadbolt 35 arranged to be movable in the length direction.
It has a latch bolt 37 which is disposed substantially parallel to 5 and movable in the length direction.

The dead bolt 35 and latch bolt 37 are each attached to the wall 31
can be engaged with holes 32 and 33 of a striker 34 attached to the striker 34 . As is well known, the latch bolt 37 is biased in the protruding direction by a spring 36. An intermediate member 51 constituted by a swinging lever is rotatably attached to the rotating shaft 50 of the lever 9 with an angle of play. The lever 9 is connected to a key cylinder of a cylinder lock (not shown) constituting a second main control device. The intermediate member 51 has a substantially fan shape, and has bent portions 51a formed on both sides thereof, which can abut the sides of the lever 9, respectively. A switch 8 is fixed adjacent to the intermediate member 51. The tip of the lever 9 is a dead bolt 35
It engages with the notch 35a of. The key inserted into the key cylinder can be removed from the key cylinder when the key cylinder is rotated to the neutral position, that is, when the lever 9 is in a substantially vertical 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 forming the notch 35a of the deadbolt 35, as shown in the figure.

At this time, the intermediate member 51 turns on the setting switch 8.

Conversely, when the key is rotated in the locking direction, the lever 9 comes into contact with the inclined surface 35c forming the notch 35a of the deadbolt 35, allowing the tip of the deadbolt 35 to be inserted into the hole 32. At this time, the intermediate member 51 is rotated counterclockwise to turn off the switch 8. Two notches 53 and 54 are formed on the outer periphery of the intermediate member 51, and the pole 56 is pressed against the notches 53 or 54 by a spring 55 to move the intermediate member 51 to the unlocked position or =19-. Hold in locked position.

The output of the counter 26 is sent to the timer 3 through the OR gate 29.
Connected to 9. The output of timer 39 is AND gate 63
67 and the second memory circuit 60. Therefore,
The output of the timer 39 causes the second memory circuit 60 to output W/R(
A high-level signal is applied to the read/write terminals to enable writing. Further, when the mode change switch 65 is turned on while the timer 39 is operating, the AND gate 63 is turned on and the number setting circuit 64 is placed in the operation mode.

By operating the numeric keypad switch 66 in this state, a numerical value can be input into the number setting circuit 64. In this state, when the mode change switch 74 is turned on, the pulse generation circuit 75 generates the same number of pulses as the number set in the number setting circuit 64, and the up/down counter 76 counts and advances the pulses of the pulse generation circuit 75. . up/down counter 76
is progressive by counting the pulses of the pulse generating circuit 75,
The output of the counter 62 is received and the count is counted down from 1 to 1.

When the up/down counter 76 decrements by one and reaches 20-0, an output is generated. The output of the up/down counter 76 is sent to the second storage circuit 6 through the OR gate 73.
Switch o to standby mode. The up/down counter 76 maintains the second storage circuit 60 in standby mode until it advances to a predetermined count value again.

Further, when the mode change switch 68 is turned on while the timer 39 is operating, the AND gate 67 generates an output and the time setting circuit 70 is switched to the operating mode. In this state, the time can be set in the time setting circuit 70 by operating the ten key switch 66. For this time setting, it is possible to input the usable time, for example, how many hours it can be used, or what hour and minute it can be used. The time setting circuit 70 is connected to a comparison circuit 71. Comparison circuit 71 compares the output of clock circuit 72 and the output of time setting circuit 70, and generates an output when they do not match, that is, when the time is outside the range set by time setting circuit 70. The output of the comparison circuit 71 is applied to the second memory circuit 60 through the OR gate 73, and the second memory circuit 60 is switched to standby mode. The number setting circuit 64, the ten key switch 66, the time setting circuit 70, the comparison circuit 71, the time it circuit 72, the pulse generation circuit 75, and the up/down counter 76 constitute the signal control circuit 44.

In the above configuration, when the switches 11 are operated in a predetermined order and the input signal is applied to the first comparison circuit 25, the first comparison circuit 25 receives the input signal and the code stored in the first storage circuit 24. When the codes match, a match signal is given to the counter 26. The input signal of the switch 11 is also applied to a second comparison circuit 61, and the second comparison circuit 61 compares the input signal with the code stored in the second storage circuit 60, and determines whether they match. At this time, a match signal is given to the counter 62 and the OR gate 28. In this case, when the code signal of the switch 11 does not match the code signal stored in the first storage circuit 24 even though any switch 11 is operated, or the code signal stored in the second storage circuit 60 does not match. When the code signal does not match the code signal, since no output signal is generated from either the first comparison circuit 25 or the second comparison circuit 61, an invalid signal is generated from the AND gate 17 via the OR gate 28 and the address counter is output. 23 is cleared.

However, when the code signal input from the switch code 1 and all the code signals stored in the first storage circuit 24 match in all digits, the counter 26 generates an output and the OR gate 4
0 to switch the Ω output terminal of the flip-flop 41 from low level to high level. Therefore, the actuator 43 is actuated to move the deadbolt 35 to the right to the illustrated unlocked state, thereby switching the locking device 30 to the unlocked state.

Next, when an output is generated from the counter 26, the Ω output terminal of the flip-flop 41 switches from a low level to a high level. Therefore, the deadbolt 35 is moved to the left locking position by the actuator 43, and the locking device 30 is switched to the locked state. In this case, the intermediate member 51 has been moved by the key to the illustrated unlocked position, and the lever 9 is in the neutral position.

Next, when the key 3 is inserted into the cylinder lock device (not shown) and rotated in the unlocking direction, the lever 9 is moved into the notch 35a.
The dead poles 1 to 35 are moved to the illustrated unlocked position by contacting the inclined surface 35b. Next, when the key is rotated in the locking direction, the lever 9 comes into contact with the inclined surface 35c of the notch 35a, and the deadbolt 35 is moved to the locked position.

The output of the counter 26 is sent to the timer 3 through the OR gate 29.
9 and the timer 39 is activated.

When the mode change switch 65 is turned on while the timer 39 is operating, the desired number of times can be entered into the number setting circuit 64 using the numeric keypad switch 66. When the mode change switch 74 is turned on after making an input using the numeric keypad switch 66, the pulse generation circuit 75 generates the same number of pulses as the numerical value set by the number setting circuit 64. The up/down counter 76 is advanced by the number of pulses of the pulse generating circuit 75.

Further, while the timer 39 is in operation, the mode change switch 68 can be turned on and the time can be set using the numeric keypad switch 66. The number setting circuits 64 and 4 and the time setting circuit 70 can also be set by rotating the key cylinder with a key and turning on the setting switch 8. The setting switch 8 may be manually operated without being linked to the cylinder lock.

Furthermore, when the timer 39 operates, the second memory circuit 60 is switched to write mode. Therefore, multiple switches 1
1, the address counter 23 can be activated and a desired code can be stored in the second storage circuit 60.

Further, when the code signal input from the switch 11 and all the code signals stored in the second storage circuit 60 match in all digits, the counter 62 generates an output and sends the output to the actuator via the OR gate 40 in the same manner as described above. 43 can be activated. Further, the output of the counter 62 is sent to an up/down counter 76, causing the up/down counter 76 to count down. When the up/down counter 76 counts down to O, the second storage circuit 60 is switched to standby mode by the output of the up/down counter 76. Further, the second memory circuit 60 is connected to the time setting circuit 7.
When the time is outside the time set by 0, the output of the comparator circuit 71 switches to standby mode.

May be used in conjunction with.

(2) Either the number setting circuit 64 or the time setting circuit 70 may be omitted.

A remote control device may be provided to provide an output.

(4) The signal control circuit 44 includes a counter that counts the number of matching signals output from the second comparison circuit 61, and a counter that controls the generation of the output of the second comparison circuit 61 when the counter reaches a predetermined count value. A blocking gate means may also be provided. The count value of the counter that controls the generation of the output of the second comparison circuit 61 can be set by the plurality of switches 11, the numeric keypad switch 66, or other means constituting the first main operation control device.

(5) As shown in FIG. 4, in the circuit using the microcomputer shown in FIG.
A permitted time is set in step 104, and it is determined in step 104 whether or not the time when the passwords match is within the permitted time, and when it is within the permitted time, the driven device 2 can be operated in step 105. If it is determined in step 104 that it is not the permitted time, the PIN number may be deleted or switched to an unreadable state in step 106.

As mentioned above, with the operation control device of the present invention, it is possible to match the PIN number only a predetermined number of times or within a desired time range. Since it can be used, a high theft prevention effect can be obtained.
