Abstract

PURPOSE:To reduce the concentration of connecting cords or peripheral equipments in the circumference of an electronic equipment, prevent wrong connection, and ease connecting action by actually leading the output signal terminal of a video signal output terminal etc., to the external power source device of an AC adapter etc. CONSTITUTION:Since a video output signal is made to be outputted from an AC coupler 17 via an attachment 16 and cord 18, in the condition where the attachment 16 is mounted within the battery housing part of a camera 1, only one cord 18 exists between the attachment 16 and coupler 17, moreover because the coupler 17 can be integrally connected to an AC adapter 15, connection can be simplified. Consequently a troublesome connection work in the condition; like where a video output signal line and a power source line are needed to be separately connected, and plural systems are required because of a independent connection cord; can be omitted, moreover because the coupler 17 can be integrally connected to the adapter 15, the connection is simplified, and wrong connection is unoccurring even if an operator has an unfamiliar technical knowledge.
