Abstract
A mechanism having at least a function of measuring an arbitrary elapsed time is provided, which disables the function from being reset after the function is started, and enables the function to be reset after the function is stopped. The function is continuously held in an electrical ON state after being started, except when being normally stopped. This provides a time measurement device and method in which an electrical operating state and a mechanical operating state can coincide.
