Title:
INTEGRATING TIME METER
Document Type and Number:
Japanese Patent JP2002329225
Kind Code:
A
Abstract:
To easily integrate the operation time of a vibration generating device.
This time meter has a vibration detector 1 which detects the vibration generated by a vibration generating device and a waveform shaping circuit 3 which shapes the waveform output pulses of the vibration detected by the vibration detector 1 and a microcomputer 4 or operation IC is made to find the integral value of the vibration generation time according to the count value of a clock while the waveform shaping circuit 3 generates the waveform-shaped output pulses.
