Abstract

PURPOSE:To obviate inadvertent malfunction and let operation state be continued until all switches are turned OFF by so arranging the unit that the operation of a control signal generating means is started by simultaneous operations of plural operation switches. CONSTITUTION:In a miniature electronic apparatus, e.g., and electronic watch, which has a control signal generating means subsequently generating different control signals according to the length of the operation continuation time of switches, the count value of a ternary shift register 10 is usually 0 and the time information of a time counter 3 is applied to a display part 5 via AND-1. As a switch S1 is operated, correction digits are selected and when a switch S2 is operated, correction is accomplished. To select a stopwatch function or another watch function and display this in the display part 5, the switches S1 and S2 are simultaneously turned ON. Even if one of the switches is inadvertently turned OFF after simultaneous ON, the operation is continued in that state even if either one of the swithces is ON.
