Claims

[Claims for Utility Model Registration] (1) A proximity sensor circuit that detects the presence of a person nearby, and a signal that is transmitted during a period when the output from the proximity sensor circuit is being sent or for a predetermined period using the proximity sensor circuit as a trigger signal. A lighting time control circuit that generates a lighting time, a light emitting means lighting circuit that lights the light emitting means according to the output of the lighting time control circuit, a light emitting means that is lit by the light emitting means lighting circuit, and a smooth end surface along the light emitting means. Trigger signal generation in which a trigger signal is generated by the output of the proximity sensor circuit in an information display device comprising a light guide plate made of a transparent plate having a structure and a film pasted on the surface of the light guide plate and having an image printed thereon. a circuit, an audio information storage means for storing digitalized audio information, a register buffer circuit for reading out information from the audio information storage means based on a trigger signal from a trigger signal generation circuit, and a register buffer circuit for reading out information from the audio information storage means based on a trigger signal from a trigger signal generation circuit; a D/A conversion circuit for sequentially D/A converting the information contained in the data; a control means for controlling the audio information storage means, the register buffer circuit, and the D/A conversion circuit; and an output of the D/A conversion circuit. An information display device equipped with a speaker that converts signals into sound waves. (2) The proximity sensor circuit includes two infrared sensors, two amplifier circuits that amplify the outputs of the infrared sensors, and a divider circuit that generates a signal corresponding to the ratio of the outputs of the two amplifier circuits. The information display device according to claim (1) of the utility model registration, characterized in that the circuit generates an output when the output of the division circuit is outside a predetermined range.
