<p>PURPOSE:To enable it to perform the lifting motion of an accurate transfer sheet taken into account of an amount of excess lifting due to inertia by installing a drive controlling means driving and controlling an impartation part imparting the transfer sheet to a discharge part on the basis of the detection of a lifting position of the transfer sheet by means of a detecting element. CONSTITUTION:When a cassette plate 33 is lifted upward by a lifting lever 34, an upper end of paper Puplifts a paper feed roller 43 upwards. A lever 44 rotates clockwise and presently crosses the detection point of a P1 sensor 45, whereby a signal P1 is outputted. In addition, if this rocker lever 44 continues its rotation, succeeding signals downward a signal P2 is outputted out of the P1 sensor 45 one after another. These outputted signals are counted, and if the count number is reached to the preset value, any rotation of the lifting lever 34 is stopped. In the case where no signal is outputted after being on standby for a little while, control is completed, and when the signal is emitted, the lifting lever 34 is driven in the reverse direction and lowered.</p> |
