It is sent to the discrimination circuit 5 and discriminated together with the previous illuminance detection signal, and condition judgment is performed in the NOR circuit 5a.
When the light should be turned on, a signal is sent to the blinking circuit 6. The blinking circuit 6 adjusts to blink light at intervals of about 1 second so that the light emission state of the light emitter 2 can be easily recognized by the driver, and the blinking signal is amplified by the blinking transistor Q1 . The blinking signal is output from the input DC6V direct current by the DC/AC inverter 7.
It is converted to AC200V and boosted, causing the light emitting element 2, EL, to blink.

信号が送られないので、振動センサ３が振動を検
出しても発光体２は点滅しない。 The above operation is an explanation of when the bag according to the present invention is used in the dark. When it is bright (30 lux or more), the discrimination circuit 5 discriminates the illuminance signal received by the optical sensor 4. Since no signal is sent to the blinking circuit 6, the light emitter 2 does not blink even if the vibration sensor 3 detects vibration.

ない。 Furthermore, even when it gets dark and the illuminance signal received by the optical sensor 4 is below a certain value (30 lux), if the vibration sensor 3 does not detect vibration, the discrimination circuit 5 makes a determination and the blinking circuit is activated. Needless to say, since no signal is sent to the light emitting element 6, the light emitting element 2 does not blink.

Even if the vibration sensor 3, which was detecting vibrations, temporarily stops detecting vibrations (for example, when a student stops), the light emitter 2 The resistor R6 of the delay circuit 12 works to excite the light emitter 2 and keep it blinking for 5 seconds.

Note that the characters written on the light emitter 2 (for example, SAFETY in the figure) only need to be confirmed when the light is bright, and whether or not the characters can be read when the light emitter 2 blinks is not an issue.
