The infrared sensor 7 is a photoconductive effect type optical sensor, and the resistance R ₁ changes from a normal infinite resistance value to a resistance value of 1 to 2 KΩ when exposed to light. The voltage BT is 6V and the contact resistance R ₂ is 13K.
Ω, and a current of 3 V and 0.2 mA flows through this contact resistance R ₂ .

Next, the circuit configuration provided in the case 4 will be described with reference to FIG. Oscillation circuit 12, frequency divider circuit 13, time counting circuit 1
Reference numeral 4 constitutes a normal clock circuit, and the time data output from the time counting circuit 14 is sent to the time display unit 3 via the display switching circuit 15 for display and is also sent to the coincidence circuit 16. The alarm time data set in the alarm time storage circuit 17 is also input to the coincidence circuit 16, so that the coincidence between the two data is detected and a coincidence detection signal is output. Give to 19.

The alarm time data is set in the alarm time recording circuit 17 by processing the operation signal by the alarm setting operation of the setting switches SW ₁ and SW ₂ provided in the case 4 by the setting circuit 20. Further, the alarm time data is sent to the display unit 3 through the display switching circuit 15 and displayed when the alarm time data is set.

The switch SW ₄ is a switch for turning on / off whether or not the wake-up pulse C is generated, and is provided in the case 4. The output is applied to the T input terminal of the T-type flip-flop 21 to set or reset it.
The set output signal is applied to the AND gate 19 as a gate control signal.
The one-shot signal output from is applied to the drive pulse generation circuit 22.

The drive pulse generating circuit 22 is driven by the high frequency clock φ from the frequency dividing circuit 13 to generate the wake-up pulse C when the above-mentioned one-shot signal is applied, and supplies it to the infrared lamp drive circuit 24 via the OR gate 23. Infrared lamp 2
5 is driven at a predetermined frequency to emit infrared rays.

On the other hand, the switch SW ₅ is a switch that starts the generation of the sleep-inducing pulse a, and is provided in the case 4.
The output signal is input to the one-shot 26 and becomes a one-shot signal, which is given to the T input terminal of the T-type flip-flop 27, and also given to the drive pulse generating circuit 29 via the OR gate 28. When the drive pulse generating circuit 29 receives this one-shot signal, it drives the clock φ to generate a sleep-inducing pulse a which is output in the state shown in FIG. Give to 24. Further, the drive pulse generating circuit 29 generates a periodic signal b once every four minutes, applies it to itself via the AND gate 31 and the OR gate 28, and again starts generating the sleep-inducing pulse a.

The set output signal of the flip-flop 27 is input to the AND gates 30 and 31 as a gate control signal, and the reset output signal is input to the timer counting circuit 32 as a reset signal. The 1-second signal from the frequency dividing circuit 13 is input to the timer counting circuit 32 via the AND gate 30 to count the timer time. Then, the timer time data is input to one end of the matching circuit 33, and the timer time set in the timer time storage circuit 34 is input to the other end of the matching circuit 33. Then, the coincidence circuit 33 detects the coincidence of both input data, and applies the coincidence detection signal to the reset input terminal R of the flip-flop 27.

On the other hand, the setting switch S is stored in the timer time storage circuit 34.
Setting of the timer time by W ₁ and SW _{2 The} operation signal by the input operation is processed by the setting circuit 20 and the above timer time is set. Then, the timer time is sent to the display unit 3 via the display switching circuit 15 and displayed at the time of setting.

The display switching circuit 15 receives the control data when the operation signal of the mode switch SW ₃ is given to the selection circuit 35, and performs an operation of switching and selecting any one of the time data, the alarm time data, and the timer time. The setting circuit 2
The control data from the selection circuit 35 is also input to 0, and the processing operation is executed.

Next, the operation of the above embodiment will be described. Before going to bed, first, the wearable body 10 is put on the head so that the first electrode 9 of the sensor device 2 hits the forehead and the second electrode 11 hits the back of the head.

Next, the main unit 1 is picked up by hand and the setting switches SW ₁ , S
The W ₂ is operated, the timer time of the timer time storage circuit 34, for example, 40 minutes and excisional, also excisional alarm time, such as 7:00 am the alarm time storage circuit 17. As a result, the set timer time of 40 minutes is given to one end of the coincidence circuit 33, and the alarm time 7:00 is given to one end of the coincidence circuit 16. In addition, these are displayed on the time display section 3 via the display switching circuit 15 at each set.

On the other hand, the oscillation circuit 12, the frequency dividing circuit 13, the time counting circuit 14
By each operation of, the current time is normally displayed on the time display unit 3.

Also after the operation of the respective switch to turn on the switch SW ₄ leave excisional the flip-flop 21, keep open the Andogedo 19 by the excisional output signal 〃1〃.

Further, switch SW ₅ is turned on and the one from one shot 26
When the output signal is output, the drive pulse generating circuit 29 is driven, the flip-flop 27 is set, and the AND gates 30 and 31 are opened by the set output signal "1". Therefore, the drive pulse generating circuit 29 has a clock φ.
5 starts to generate a sleep-inducing pulse a having a gradually changing frequency as shown in FIG. 5, and supplies it to the infrared lamp drive circuit 24 to cause the infrared lamp 25 to emit infrared rays.

That is, this infrared ray changes according to the frequency change of the sleep-inducing pulse a, and 14 Hz for 10 seconds after the switch SW ₅ is turned on.
The frequency gradually decreases to 10 Hz for the next 80 seconds, keeps 10 Hz for the next 7 seconds, decreases to 0 Hz for the next 90 seconds, and stops emitting infrared rays for the next 53 seconds.
It is emitted with the frequency of the state that the periodic signal b of the emission is generated and the first period is finished. And this infrared
The infrared sensor 7 of the person's head lying on his back under the infrared light emitting unit 6 receives the light, and the output is input to the first electrode 9 to form a lead wire (not shown) with the second electrode 11. A current of about 3V, 0.2mA flows through it and flows into the human body.

On the other hand, since the AND gates 30 and 31 are opened after the switch ₅ is turned on, the timer counting circuit 32 counts the 1-second signal and measures the timer time.

Further, the periodic signal b output at the end of the first period is transmitted through the AND gate 31 and the OR gate 28 to the drive pulse generating circuit 2
Since 9 is driven, the circuit 29 again starts to generate the sleep-inducing pulse a in the same state as the one cycle described above, and the infrared ray is restarted to be emitted at the frequency corresponding thereto.

And after on the switch SW _5, the hypnotic pulse a of 10 cycles stood 40 minutes to complete generation, coincidence circuit 33 timer time 40 minutes being excisional the timer time storage circuit 34, the timer counting circuit 32 A coincidence with the clocking time of 40 minutes is detected, a coincidence detection signal of "1" is generated, and the flip-flop 27 is reset. Therefore, the timer clock circuit 32 is also reset by the reset signal 〃1〃,
The timing operation is also completed.

Then, during the 40 minutes, a sleep-inducing pulse for 10 cycles is generated, and infrared rays corresponding to that are emitted for 10 cycles, so that the person falls asleep by the sleep-inducing action.

When the morning comes and it is 7:00 am, the coincidence circuit 16 detects the coincidence between the set alarm time and the present time, generates a coincidence detection signal of "1", and gives it to the buzzer 18 and the AND gate 19. . Therefore, the buzzer 18 is driven to start emitting the alarm sound. And gate 19
The drive pulse generating circuit 22 is driven by the output of the awakening pulse, the wakeup pulse C is started to be output, and is supplied to the infrared lamp drive circuit 24 via the OR gate 23. Therefore, the frequency of the wakeup pulse C is supplied from the infrared lamp 25. Infrared radiation is started to be emitted in a state corresponding to the above state, and is received by the infrared sensor 7 so as to prompt the user to wake up. Therefore, upon awakening, the switch SW ₄ is turned off and the flip-flop 21 is reset. Therefore, Andgate 19 was closed,
The drive pulse generation circuit 22 stops its operation and stops the generation of the awakening pulse C. Therefore, the emission of infrared rays also ends.

Although the photoconductive effect type optical sensor is used in the above-mentioned embodiment, it may be a photovoltaic effect type optical sensor, and if the photovoltaic effect type optical sensor is used, the sensor device does not include a battery. However, it is possible to generate the predetermined voltage and current only by the electromotive force of the optical sensor.

In addition, although infrared rays are used as light in the above-mentioned embodiment, it is needless to say that other light may be used instead of infrared rays.

〔The invention's effect〕

As described above, the present invention is an electronic sleep apparatus in which an optical sensor is attached to the head, and infrared light whose frequency is gradually changed in a constant cycle is emitted from the infrared light emitting body with respect to the optical sensor. Therefore, it is not necessary to connect the main body device and the optical sensor with a wire, and therefore, there is also an advantage that the user does not have a strong feeling of wearing and can easily sleep.
