Abstract

PURPOSE: To realize a clear display of the usable time for an electic apparatus which is driven by the battery being charged when it is not in use, by displaying the working time of the electric apparatus by the timer display means which doubly used for the time display means.
CONSTITUTION: The power supply battery 26 for the soldering iron 20 and others forming the electric apparatus is charged when not in use and via the transformer and others of the receiving board 10 and then reaches the prescribed voltage level. Thus the down-counter, the timer decoder and the like are reset to the initial state via the battery voltage detecting circuit 56. On the other hand, the time is displayed on the display unit 70 by the driver 52 and via the timepiece circuit consiting of the divider circuit 44, the clocking circuit 46 and others. With use of the iron 20 with the switch 28 closed, the AND gate 54 is closed. Then the division output of 1Hz supplied from the circuit 44 is down-counted from the prescribed value and through the counter 60, and the usable time of the iron 20 is displayed clearly on the unit 70 via the display switching circuit 50 which is changed over to the timer display.
