摘要： A wall stands upright from the surface of the bottom plate in the vertical direction in an electronic apparatus. An opening is defined in the wall. A connector defines a cylindrical portion located in the opening to receive a plug. A rib stands upright from the surface of the bottom plate. The rib defines a lock surface and an inclined surface. The lock surface extends in the vertical direction so as to hold the connector between the wall and the lock surface itself. The inclined surface is connected to the upper end of the lock surface. When the connector is set within the enclosure, the connector is received on the inclined surface. The connector slides on the inclined surface. The cylindrical portion enters the opening. When the connector drops off the inclined surface, the connector is fitted between the lock surface and the wall.

摘要： A method for detecting the charged state of a battery based on the measurements of open circuit voltage in which the charged state of a battery can be detected precisely regardless of the degradation state of the battery. Internal impedance of a battery is measured, voltage of the battery is measured under stable state, measurement of the battery voltage under stable state is subjected to raising correction depending on the measurement of internal impedance, and then charged state of the battery is determined based on the corrected value of battery voltage under stable state.

摘要： A cover is coupled to a base with the inner surface of the cover opposed to the inner surface of the base. In this case, a rib standing from the inner surface of the cover is guided along the contour of a printed wiring board fixed to the inner surface of the base. The method allows the printed wiring board on the base to guide the movement of the rib of the cover. The printed wiring board is utilized to align the cover with the base with a higher accuracy. The cover is thus reliably prevented from colliding against an electronic component mounted on the printed wiring board. This results in a reliable avoidance of damage to the electronic component.

An operating piece is located along the outer surface of the enclosure. A connecting piece is located along the inner surface of the enclosure. The connecting piece is connected to the movable piece of the switch element. A sliding piece extends around the edge of the enclosure to connect one end of the operating piece to one end of the connecting piece. The sliding piece is designed to slide on the edge of the enclosure. The movable piece of the switch element moves between the switch-on position and the switch-off position in response to the movement of the operating piece.
