<p>PURPOSE:To ensure the operation of a lock lever by providing a cassette spring and hence pressing upward a lower side surface of a cassette in upright posture on a lower side plate of a slider. CONSTITUTION:An upper periphery of a slider side plate 2 on the right side, which becomes the upper side when the cassette (m) is in the upright posture, is formed integrally with a bracket 2A bent toward the inner side. This bracket 2A is fitted by caulking with a cassette pressing leaf spring 3 for elastically pressing the cassette (m) against the slider 1. Then, an upper periphery of a slider side plate 2 on the left side is formed integrally with a cassette positioning piece 2B for positioning the cassette (m) in contact with its upper surface, bent toward the inner side. Then, the cassette (m) is pressingly energized upward on its lower side surface by the cassette spring 3B on the side plate 2 on the lower side. Consequently, the operation of a lock releasing lever for a front lid of the cassette (m) can be ensured with a simple structure.</p> |
