Abstract
A time switching power saving system for electronic indicators which comprises an indicator operated by a battery and a time switching indication control circuit for controlling the operation of the indicator in such a manner that the indicator makes a continuous indication for a predetermined time period from the start of indication and then makes an intermittent indication after the predetermined time period has passed, so that the power consumption of the circuit is decreased without stopping the operation of the indicator.
Claims5
A time switching power saver circuit for a battery powered electronic indicator comprising:
- A. an indicator for displaying figures connected to be supplied with a DC power supply voltage by a battery;
- B. control means having an indicator instruction signal input, said means effective to control a time switching means in accordance with the state of an induced instruction time signal;
- C. switching means connectedd to said control means, said time switching means generating in response to said instruction signal a switching signal;
- and
- D. indication control means connected between said time switching means and said indicator for receiving said switching signal to control the indication of the latter, said indication control means being responsive to said switching signal for controlling the indicator to first make a continuous indication for a predetermined time period in response to the indication signal and to later automatically make an intermittent indication also in response to said switching signal.
