PURPOSE:To use a main body again by resetting use remainder frequency by the reset means of a battery case to be used attachably to/detachably from the main body. CONSTITUTION:In the state of connecting an electrode 19a with an electrode 15a and an electrode 19c with an electrode 15c, by connecting a conducting face 24 with a reset terminal 14, a reset signal is given and the use remainder frequency of an EEPROM is reset. A user resets a time control equipment 1 like this, after that, pulls a battery case 17 out of a casing 2, fits a newly bought battery case 17 into the outside space of the casing in the state of fitting a reset preventing pint 16 and uses the time control equipment 1 again.
