Abstract

PURPOSE:To make it unnecessary to take a battery charger from equipment whenever it is charged by providing a charging means in a reproducing device, and charging the battery charger in a loaded condition to the reproducing device. CONSTITUTION:A reproducing device 3 is provided with a charging means 65. When a camera 2 is not connected to the reproducing device 3, the charging means 65 charges a battery charger 35 of the reproducing device 3, and when the camera 2 is connected to the reproducing device 3, a battery charger 18 of the camera 2 can be charged by the charging means 65. Thus, since the batter chargers 18 and 35 can be charged in the loaded condition to the camera 2 and the reproducing device 3, it is made unnecessary to take the battery chargers 18 and 35 out of the equipment whenever they are charged.

The purpose is to

(C, Prior Art) In general, many cameras can use a disposable primary battery or a reusable rechargeable battery as a power source, and when using a rechargeable battery, a dedicated charging device is required.

(D. The problem that the invention attempts to solve! However,
A problem with using conventional cameras is that when the rechargeable battery is used up, it is a hassle to remove it from the camera and attach it to the charging device to charge it, which is especially true for electronic still cameras. If the camera body and playback device are separated and each has its own rechargeable battery, the effort will be doubled.
