Abstract
PURPOSE:To reduce the size and cost of a timepiece by providing means for selecting a correction operation and correction position change-over by the on time of a switch. CONSTITUTION:A microcomputer (MC) 1 is one-chip MC constituted of a CPU, RAM, ROM and input/output port, etc. An external switch 2 for changing over an ordinary time display and correction state as well as for making correction is connected to the input port of the MC 1. The on and off states of the switch 2 are thereby converted to binary codes which are read into the MC 1. The time when the switch 2 is on is set in the RAM or ROM of the MC 1. For example, the time is previously set in 2 stages; below 1 second and >=1 second; then, the correction is made at the timing of the off when the switch 2 is turned off after the switch is held turned on for the time below 1 second. The correction position is changed over at every 1 second after the switch is turned on during the on of the switch is the switch is turned on for 1 second. The size and cost are thus reduced.
