Title:
ELECTRONIC APPARATUS
Document Type and Number:
Japanese Patent JP2006196213
Kind Code:
A
Abstract:

To solve a problem in an electronic apparatus such as a digital camera, wherein, in conventional static discharge countermeasures, a grounded conductive member is arranged between a joint of an armoring cover and a circuit board or a contact spring in contact with a negative terminal of a battery disposed in the electronic apparatus is extended and brought into elastic contact with a conductive member other than the battery, and the conductive member is arranged in an intrusion path of static; however, the number of components and assembly manhours are increased because of newly adding the conductive member; or static discharged from the armoring cover joint toward the circuit board can not be prevented in the case of a structure where the conductive member is not arranged in a space between the armoring cover joint and the circuit board.

By extending a part of the battery contact spring 12 equipped with a conductive terminal electrically connected to the negative terminal of a battery by bringing them into contact with each other, and by stting a distance to a part 12a thereof extended from the armoring cover joint 13 smaller than a creeping distance from the armoring cover joint 13 to the circuit board 14, static in the air is prevented from being discharged to the circuit board 14 in an electronic apparatus.
