力回路。[Claims for Utility Model Registration] (1) In an input circuit configured to control a control circuit corresponding to an input key operated, when the input key is operated, the control circuit is controlled to have a brightness higher than a set value. An input circuit comprising means for enabling the control circuit to be controlled by operating the input key only when the input key is operated. (2) In an input circuit configured to control a control circuit corresponding to an input key operated, a first means for bringing the control circuit into a controllable state when the input key is operated; and a predetermined value. a second means for controlling the control circuit by operating the input key only when the brightness is above the brightness level;
and a switch means for switching the second means. (3) In an input circuit configured to control a control circuit corresponding to an input key operated, a first means for bringing the control circuit into a controllable state when the input key is operated; and a predetermined value. a second means for controlling the control circuit by operating the input key only when the brightness is above, and a third means for bringing the control circuit into a non-control state even if the input key is operated and regardless of the brightness. and a switch means for switching the first to third means.
