| 摘要 | PURPOSE:To reduce size by providing a rotatably supported contact press frame with a conductive part and a contact cam, and by arranging a couple of spring contact plates successively corresponding to the conductive part. CONSTITUTION:A contact press frame 35 supported rotatably on a bearing 29 is provided with a contact piece 3b which corresponds to the recess part 11a of each digit number wheel 11 and a projection 37 projected upright at the right end part of the reverse surface in one body. At the reverse-surface part of the projection 37, a conductive part 39 is formed nearly in a semicircular arc shape. On the reverse surface of the projection 37, a contact cam 40 is formed in one body behind the conductive part 39. On the internal surface of a contact housing 45, a couple of spring contact plates 51 and 52 are provided successively. The contact 55a of one spring contact plate 51 is normally pressed by the conductive part 39 of the contact press frame 35 to charge elasticity, securing adequate pressure for contact with and release from the conductive part 39. On the other hand, the contact 55b of the other spring contact plate 52, while a projecting piece 36 is not fitted in the recess part 11a of a cam 15A, is pressed by the contact cam 40 to charge elasticity, thereby holding itself in noncontact with the conductive part 39. | ||||||
