Abstract

PURPOSE:To check the battery replacement time at any time, and to protect an important data by using a switch in common for a battery voltage check, an automatic return mechanism after the battery voltage check, and an inhibition and a permission of write of a data. CONSTITUTION:The titled device is constituted of a battery 7 for holding a data, a detecting circuit 9 for detecting a battery voltage, a display element 12 which can be discriminated by a visible light, a control terminal 3 for controlling the display element 12, and one switch 10. The switch 10 is a switch used in common for a battery voltage check, an automatic return mechanism after the battery voltage check, and an inhibition and a permission of write of the data. In such a way, the battery replacement time can be known by the check switch 10 at any time when necessary.
