<p>PURPOSE:To enable the release from a set position and drawing and inserting operation of a carrying unit by disposing an operation lever capable of switching between a first position in which the carrying unit can be mechanically moved and a second position making its moving operation possible. CONSTITUTION:When a carrying unit 40 is situated in a determined set position where it can be mechanically moved, an operation lever 84 is held in a first position, whereby the carrying unit 40 is engagingly locked in a determined position. The locking of the carrying unit 40 to the machine body is released by rotating the operation lever 84 to a second position, and the carrying unit can be drawn out with the operation lever 84 in the hand. In the process of drawing and inserting the carrying unit 40, as the rotation of the operation lever 84 is inhibited by a regulation means, the operation can be smoothly conducted. An interlocking mechanism for making a part of the carrying unit, for example, a carrying belt, contact with and separate from a sensitizing body 14 in the machine body interlockingly with the switching operation of the operation lever is provided, and these both members are prevented from sliding and damaging in the process of moving the carrying unit.</p> |
