Abstract

The invention discloses a writing distance and time-indicating device which is characterized by comprising a plastic shell on which a control switch and a light dependent resistor are arranged; a control circuit and a light dependent resistor which are arranged in the shell are connected with a timer and a buzzer circuit that are arranged in the shell as well. When in use, after the switch is pressed, the indicator can be put on a writing learning desk and can also be hung on a computer screen facing the face of a grapher. When the distance between the face of the grapher and a book or the computer screen is less than one foot, the light dependent resistor in the indicator starts the buzzer to emit an alarming sound of 'toot toot toot'; when the grapher uses eyes for a certain time, the timer also drives the buzzer to emit an indicating sound of 'wu wu wu'.
