Motor rotation switching mechanism

Abstract

Abstract PURPOSE: To change the direction of rotation of a motor by turning a battery case relative to a body case. CONSTITUTION: The half and annular fitting part 6a of a battery case 6 is rotatably fitted in a groove 1c formed in the circumferential face of the end of a body case 1. A battery 7 is connected with said battery case 6 by a conducting plate 8. The rear end face of a motor 2 is provided with a notched groove, into which the positive terminal 2p and negative terminal 2n of said motor 2 are inserted, and an annular holder 9 for holding said positive and negative terminals 2p, 2n is fastened to said rear end face. Thus, when the battery case 6 is turned relative to the body case 1, the positive and negative electrodes 7p and 7n of the battery 7 and the positive and negative terminals 2p and 2n of the motor 2 are connected or cut off respectively, and, moreover, the connection between both electrodes 7p, 7n and that between both terminals 2p, 2n are changed from each other. Therefore, this apparatus can be manufactured with a very simple constiution and with the necessary and minimum parts. COPYRIGHT: (C)1989,JPO&Japio
