PURPOSE:To avoid wrong installation of an electric power unit for reliable attachment and detachment by installing stopping members in the electric power case installation face wherein the kind of an electric power supply from outside is distinguished by the members. CONSTITUTION:On the installation face 2 of a VTR main body 1 integrated with a video camera, a pair of square rod-type stopping members 9, 10 are so projected as to face to both end edge parts in the longitudinal direction of an upper side case 5, and projected parts 8A-8D are formed on the opposite face. While an electric power case 3 being pushed toward the main body 1, the case 3 is slid transversely, so that the case 3 is fixed between the members 9, 10 in the way it can be detached freely. There area recessed and projected parts 34, 35 which show the kind of the usable electric power unit and projected parts 36, 37 are formed in the main body 1. Consequently, an electric power unit is attached to the main body 1 in the way it can be deteched freely only by fixing the projected parts 8A-8D in the notched parts 7A-7D. |
