Claims (1)

[Claims for Utility Model Registration] A reference signal source, a dial having a time indicator,
An analog display timepiece having hour and minute hands that indicate the time on the dial, and an electromechanical conversion circuit that rotationally drives the hour and minute hands in response to a reference signal from the reference signal source, the dial comprising: It has luminous time markers arranged corresponding to the upper time markers and capable of selectively emitting light in two colors, and the same number of output lines as the luminescent time markers, and receives a reference signal from the reference signal source. a minute counter that counts the time of the minute and outputs a lighting signal to one of the corresponding output lines; and a minute counter that has the same number of output lines as the number of luminous time markers, and that receives a carry signal from the minute counter. an hour counter that counts the hour and outputs a lighting signal to one of the corresponding output lines; an alarm hour and minute memory capable of storing the hour and minute of the alarm time; a coincidence circuit that detects coincidence of count contents of hour and minute counters, an alarm switch circuit that controls on/off of an alarm, a notification circuit that receives and issues a coincidence signal from the coincidence circuit, and from the alarm switch circuit. an AND gate that can supply a coincidence signal to the notification circuit only when an alarm-on signal is generated; a mode switching circuit that can be switched to at least a non-correction mode, an alarm-time correction mode, and an alarm-minute correction mode by external operation; and a correction counter that increments the count value for each external operation only in the minute correction mode, and a correction counter that presets the count value of the correction counter in the alarm correction mode in response to an external operation and sets an alarm. a preset circuit that outputs a preset signal that presets the count value of the correction counter to the alarm minute counter in the minute correction mode; and a timer circuit that outputs a timer signal only for a certain period of time from the generation of the alarm-on signal from the alarm switch circuit. The count signals from the correction counter and the alarm hour and minute memory are input, and in non-correction mode, the count signal of the correction counter is output, and in other cases, the count signal from the alarm hour and minute memory is input. a multiplexer for outputting a signal; and a count signal from the multiplexer is input, and when the timer signal is generated and in an alarm correction mode, a signal that causes one of the light emitting time markers corresponding to the count signal to emit light in one color is set at the light emitting time. a lighting circuit that outputs a signal to the light emitting time mark that causes one of the light emitting time marks corresponding to the count signal to emit light in the other color when the timer signal is generated and in an alarm minute correction mode; An analog display clock characterized by:
