JPS5968630A - Illuminometer with illuminance-musical scale converting device - Google Patents

Abstract

PURPOSE:To make it possible that the user produces optionally a musical scale corresponding to the quantity of light and this musical scale is played, by intercepting partially the light irradiated to an optical sensor with the palm of his hand or the like to change the quantity of light in the titled illuminometer used in an electronic clock or the like. CONSTITUTION:When the user inputs sound ''do'', he intercepts partially the light irradiated to an optical sensor 1 with the palm of his hand or the like. Then, a CR oscillating circuit 2a uses an electromotive force C corresponding to the illuminance from the optical sensor 1 as the power source to output a frequency signal D. At this time, if a counter 2C is preliminarily reset by a pulse G1 from a generating circuit 9 and it is the time when a pulse G2 from the generating circuit 9 is changed from logical level ''Low'' to ''High'', an AND gate 2b permits the frequency signal D from the CR oscillating circuit 2a to pass through only for about 1msec by the pulse G2, and the counter 2c is operated to count it.
