Abstract
A timer apparatus having a power source, a timer unit for outputting time information to which a time is set via a setting terminal, and a control unit in which a program for permitting set of a time in the timer unit only once is written from the outside via a write terminal and which controls the timer unit. After the program is written to the control unit via the write terminal, the write terminal is disconnected, and the power source, timer unit and control unit are molded integrally. A low-cost timer apparatus in which a time cannot be changed incorrectly can be realized without mounting a processor for performing a complicated process.
