Document Type and Number:
Japanese Patent JP2010107350
Kind Code:
A
Abstract:

To correctly measure an operating time of an engine, and simply and inexpensively configure a display means by using a light emitting diode.

A pulse is induced by a power generating coil 11, and perceived by a pulse perception means 18. The operating time of the engine is measured by an engine operating time measuring means 19 based on a pulse perception output from the pulse perception means 18. Each time the operating time of the engine measured by the engine operating time measuring means 19 reaches a predetermined time, the light emitting diode 17a is lighted by the lighting output means 20 for a fixed time set by a timer.
