Next, the operation of the sleep control glasses will be described.

For example, a driver of the mechanical device wears the sleep control glasses like ordinary glasses, and turns on a power switch provided on the temple 12L.

First, while the eyelid open / close detectors 20L and 20R can properly detect the open / closed state of the eyelids by the appropriate detection monitor means 60, various settings are made so that appropriate detection is possible. . For details, see the monitor switch 6
While pressing 2L, the direction of the eyelid opening / closing detector 20L is adjusted by a direction adjusting means (not shown) so that the LED 61L blinks (confirms with the right eye) in response to the opening and closing of the eyelid while repeatedly opening and closing the left eyelid. It adjusts or adjusts the variable resistor 33L for adjusting the sensitivity of the amplifier 32L provided on the temple 12L. Similarly, while pressing the monitor switch 62R and repeating the opening and closing of the right and left eyelids, the direction of the eyelid opening and closing detector 20R is changed so that the LED 61R blinks (confirms with the left eye) in response to the opening and closing of the eyelids. The variable resistor 33R for adjusting the sensitivity of the amplifier 32R provided in the temple 12R is adjusted by the direction adjusting means.

After the adjustment regarding the detection operation of the eyelid opening / closing detectors 20L and 20R is completed, the actual sneezing prevention operation is started. The output of the phototransistor 22 corresponding to the open / closed state of the eyelid is amplified by the amplifiers 32L and 32R. A signal corresponding to the amplified opening / closing state of the eyelid is output to a comparator 34.
L and 34R compare with a predetermined threshold value, and the comparators 34L and 34R output a binary signal indicating whether the eyelids are open or closed.

The control unit 31 to which the outputs of the comparators 34L and 34R are input calculates the time ratio between the opening and closing of the eyelids,
If the state in which the eyelid closing time is equal to or more than a predetermined value (for example, 20%) with respect to the eyelid opening time continues for a predetermined time (for example, 2 seconds), it is determined that the eyelid state is occurring.

When the control unit 31 determines that the vehicle is in the sleep state, it outputs a sleep detection signal to that effect. In the case of this example, the sneezing detection signal is transmitted to the detection signal transmitting unit 40.
Of the driving signal of the infrared LED 41 and the driving signal of the speaker 51 of the alarm notifying means 50. The sleep detection signal is transmitted from the wearer to the monitor switches 62L and 62L, for example.
Output is continued until one of the 2Rs is pressed.

When a digital code drive signal is input as a sneeze detection signal from the control unit 31, the detection signal transmitting means 40 transmits the infrared code from the infrared LED 41 to the outside.

The detection notification stage 50 receives a loudspeaker drive signal from the control section 31 as a sleep detection signal.
An alarm sound or the like is output from the speaker 51. In addition, switch 5
2, the alarm sound can be cut off, or the alarm volume can be adjusted by the variable resistor 53.

A sleep detection signal (infrared ray) is received by the phototransistor 102. The received signal is amplified by the amplifier 103 and compared with a predetermined threshold by the comparator 104. Based on the result of the comparison by the comparator 104, it is determined whether or not the apparatus has received the swell detection signal. When determining that the sleep detection signal has been received, the control unit 101 outputs a control signal C to a control unit of an external mechanical device (not shown).
