PURPOSE:To make it possible to simplify the structure and control of an electrostatic copying machine, by providing a paper feed means in an intermediate stock section for copying papers having one surface already copied, such that either on of the inoperative condition, weak pressure condition and strong pressure condition may be selected. CONSTITUTION:The inner surfaces of width aligning members 24 act upon both side edges of copying papers when a solenoid 64 is energized, and the solenoid 64 is deenergized when copying papers on an intermediate tray 36 is set at a predetermined position. Accordingly, swingable support members 48a, 48b are rotated counterclockwise due to the weight of a paper feed roller 44, etc. and are therefore made about against the upper surface of the copying papers with a relatively weak pressure. Further, the copying papers having one surface copied with an image are stacked and aligned together on the intermediate tray 36 to be temporarily accumulated thereon. Therefore, solenoids 80, 62 are energized to shift a movement inhibiting member 74 to its inhibiting position while the paper feed roller 44 is pressed against the upper surface of copying papers on the tray 36 with a relative strong pressure, and therefore, the copying papers are surely fed toward a pair of rollers 76, 78. With this arrangement the control may be surely made with a simple structure. |
