Patent Searching and Data


Title:
ELECTRONIC DEVICE, FLASH LIGHT GENERATING DEVICE AND DISCHARGE METHOD
Document Type and Number:
Japanese Patent JP2010164838
Kind Code:
A
Abstract:

To reliably allow a capacitor of an electronic device to discharge when the device is shocked.

The electronic device includes: the capacitor unit which accumulates charge supplied from a power supply in space between a pair of electrodes and supplies power to a load by discharge; a shock detection unit which generates an electrical signal while power is not supplied from the power supply when shock exceeding a given threshold is given; and a discharge unit which short-circuits the pair of electrodes while the power is not supplied from the power supply when the electrical signal is received. A light source for continuous light may be supported in a housing to be arranged in a direction where continuous light illuminates a lower side of the housing when a light source for flash light faces to an object to be illuminated.
