Title: Electronic time piece with bathometer
Inventor: KAWAHARA HISASHI
IPC: G04G9/00
Filed: 1986-09-17
Abstract: PURPOSE:To obtain an electronic time piece with a bathometer characterized by a long battery life and high reliability, by generating a lamp illuminance control signal based on water depth information, and switching lamp driving currents stepwise. CONSTITUTION:At the time of normal operation, a switch MS is OFF, and a mode specifying and controlling signal PC is 'L'. Time-piece information PZ of a time-piece circuit 1 is outputted as display information PH from a display switching circuit 5. The time is displayed on a display device 7. When the switch MS is turned ON at the time of dividing and the signal PC is made 'H', a power source control circuit 12 is operated, and a bathometer circuit 8 is driven. Water depth information PS is outputted. At the same time, the water depth information PS is outputted as the display information from the circuit 5, and the water depth is displayed on the device 7. When a lamp switch LS is depressed in the water, illuminance control signals P1-P4 are sent out of a lamp illuminance control circuit 15 in correspondence with the water depth information PS. The collector current of a transistor is controlled through resistors R in a lamp driving circuit 16. The minimum illuminance corresponding to the darkness in the water is selected. Power consumption is decreased, and a battery life is elongated. Thus the highly reliable water depth circuit is obtained.
