<p>PURPOSE:To surely convey a sheet by operating a spring which can transmit lift operation of a lift member to a sheet conveying means, between the lift member and the sheet conveying means. CONSTITUTION:When a cam 74 is turned in the clockwise direction, one end side of an intermediate lever 81 is gradually lifted and moved upward by a circular arc surface 74a. A press-moving lever 83, pivotally supported to a point end of the intermediate lever 81, tends to move integrally with the intermediate lever 81 by the energizing force of a coil spring 84 to press-move a supporting frame 72, and it is moved upward by lifting one end side of the supporting frame 72. When the supporting frame 72 reaches a predetermined position, it is stabilized in a predetermined upward moving position through the intermediate lever 81 and the press-moving lever 83 by bringing a plane part 74b into opposed contact with the intermediate lever 81 and stabilizing the plane part between itself and the intermediate lever 81 after it is excessively press-moved by a corner part 74c of the cam 74. In this way, a transcription sheet can be surely conveyed.</p> |
