TEMPERATURE MEASURING DEVICE

摘要

PURPOSE:To simplify operation while simplifying and miniaturizing constitution, by performing the start and stop of operation and the change-over display of a previous measured temp. value and a present measured temp. value corresponding to the operation of a single switch and the operation lasting time of said switch. CONSTITUTION:A judge part consisting of a counter 4 and a latched circuit 5 judges that a switch 1 was operated. When the switch 1 is operated for a period shorter than the count period of the counter 4 after the operation of a temp. measuring part 10 was started, all operations are stopped but, when the switch 1 is operated for a period longer than the count period of the counter 4, the display corresponding to the previous measured temp. value stored in a memory part 12 is performed on a display device 15 until the switch 1 is operated for a period shorter than the count period of the counter 4 in the next time.
