And the signal from the signal output control unit 17 is turned ON or OF.
The control signal opening / closing switch 8 for turning on and off is used to monitor light reception and output a signal such as ringing when the light reception time exceeds a specified value or control other devices.

As shown in FIG. 2, when the light receiving sensor 2 senses light such as indoor lighting or sunlight, a signal is transmitted to the timekeeping controller 11. The timing control unit 11 constantly monitors whether the transmitted signal exceeds a preset threshold value, and once the threshold value is exceeded, the timing control unit 11 transmits a measurement instruction to the light reception detection time measurement timer. Has become. The timekeeping control unit 11 monitors the level of the input signal based on the threshold value by using, for example, a comparator circuit including an operational amplifier.

The photodetection time measuring timer 12 measures the photodetection time under the control of the clock control unit 11. The light reception detection time is measured by items such as month, day, day of the week, hour, minute, and second. For the measurement, the start time and end time are measured for items such as the month, day, day of the week, hours, minutes, seconds of light reception.

The light receiving detection time measuring timer 12 receives accurate time information from the clock unit 12a in order to perform accurate measurement. In order to supply accurate time information, the clock unit 12a may be, for example, a radio clock or GPS.
(Global Positioning System)
It is designed to be constantly calibrated based on the time information.

In the light-reception detection time pattern creation unit 13, each item such as month, day, day of the week, hours, minutes, seconds, and light-reception time is based on the start and end times of light reception measured by the light-reception detection time measurement timer 12. A light reception detection time pattern is created by using as an index. In creating the index and the pattern, the pattern is created by a method that facilitates pattern matching later. Pattern matching methods and heuristics (he

Other significant methods are not excluded.

The light-reception-detection-time pattern storage unit 14 stores the operation of the determination unit 16 when the light-reception-detection time pattern created by the light-reception-detection time pattern creating unit 13 is a new pattern that has never been detected in the past. By instructing the control unit 15 to perform a control operation, the received light detection time pattern is stored in the light reception detection time pattern storage unit 14 and collated with the light reception detection time pattern created by the light reception detection time pattern creation unit 13 thereafter.

The mode changeover switch 6 is a rotary type switch, and is of OFF (AUTO) mode, A mode, B mode.

The phase shift switch 7 outputs when the stored detection time pattern of the received light and the detected detection light time pattern of the received light are the same as the mode (forward mode) for outputting a signal from the signal output control unit 17. It is a conversion switch for switching between (reverse mode). For example, when it is used for crime prevention, when a light-receiving pattern that is different from the normal pattern is detected / judged, it is notified in the reverse mode, and when a light-receiving pattern that has been detected in the past during data accumulation is output, Forward mode is used to notify.

The control signal open / close switch 8 is a switch for opening / closing the control signal when the signal of the signal output control section 17 is not used. For example, when the signal of the signal output control unit 17 is connected to a ringing device or the like, it is switched and used when the ringing device is not operated.

The ringing device 9 is controlled by the judging section 16 when the detected content of the light receiving pattern reaches a certain condition.
It receives a signal from the signal output control unit 17 and sounds to notify. The ringing device 9 may be replaced with, for example, a device which sends an alarm signal by wire or wirelessly.
