KR960043587A - Cordless pager - Google Patents

Abstract

The present invention relates to a radio pager, which includes a high frequency reception / amplifier (11, 12), a mixer (13), an oscillator (14), an intermediate frequency detector (15), a decoder (16), a controller (17), In a conventional wireless pager including a key input unit 18, a display device driver 19, a display device 20, an alarm / vibration generator 21, and a light 23, it detects the amount of ambient light. The optical sensor unit 30 is further installed to convert the detected light amount into digital data and apply the same to the controller 17, and the controller 17 is based on the light amount data detected by the optical sensor unit 30. It is characterized by controlling the illuminance level and on / off of the low light 23, and the illuminance and on / off of the light are automatically adjusted according to the brightness of the attention, thereby saving power and minimizing battery consumption. In addition, the illumination intensity and on / off of the light is automatically controlled to increase the user's convenience.
