More particularly, the invention relates to a feeding device that has a pivotal copy material holding plate for lifting up copy material, the holding plate being let down when a copy material storing unit of the feeding device is removed from the main body of the apparatus.
  • the present invention aims to provide a feeding device in which the feeding end of a copy material feed unit is prevented from touching with the copy material feeding mechanism provided within the main body of the apparatus to which the feeding device is adapted, when the copy material feed unit is taken out from the main body for supplying paper or settling a jam.

  • the plate 34 is provided with another opening (not shown) at the paper stacking position for lateral feed. Therefore, when no paper is placed on the pivotal paper holding plate 34, the actuating segment 83a pierces the opening so that the paper detection switch 83 is not switched ON while the detection switch 82 is switched ON. On the other hand, when papers are placed on the pivotal paper holding plate 34, the detection switch 82 and the paper detection switch 83 are both switched ON.
  • the rotating section 35 is rotated in the direction indicated by the arrow A. Since the rotating section 35 is connected to the moving block 50 and the moving block 50 linearly moves, the center of the rotation of the rotating section 35 is moved. Such a movement is controlled by the arm 32 for pivotally supporting the rotating section 35. More specifically, the arm 32 rotates on the pivot pin 31 in the direction indicated by the arrow D, thereby ensuring the movement of the rotation of the rotating section 35. The rotation of the arm 32 in the direction indicated by the arrow D is carried out until the line X between the pivot pin 50a of the moving block 50 and the pivot pin 32a makes a right angle with the guide shaft 51.
  • the rotation of the rotating section 35 from the longitudinal feed position to the lateral feed position can be achieved by reversely rotating the driving motor 41 and carrying out the operations opposite to the foregoing procedures.
  • the position detection switch 100 is switched ON by the switch actuating segment 52b of the holding member 52.
  • the control unit of the copying machine 1 detects the operation of the position detection switch 100 and controls the first clutch 44 to suspend the transmission of the driving force, thereby halting the movement of the moving block 50.
  • the coupling part 55a is disengaged from the coupling part 55b in the first coupling 55 and the coupling part 58a is disengaged from the coupling part 58b in the second coupling 58, whereby the transmission of the driving force of the driving motor 41 to the lift member 40 is suspended.
  • the lift-up shaft 60 gets free, and the lift member 40 is pivoted downward by its own weight, so that the pivotal paper holding plate 34 is released from its raised condition to be let down.
  • the coupling parts 55a and 58a are disengaged from the coupling parts 55b and 58b respectively, when the rotatable cassette unit 26 or 27 is drawn 6mm from the main body for example.
  • Fig. 2 shows a condition in which the cassette 26 or 27 is drawn 26mm from the main body and the coupling parts 55a/55b, and 58a/58b are completely disengaged.
  • the mechanism for raising/lowering the pivotal paper holding plate is adapted to a rotatable cassette, but the invention is not limited to this.
  • the mechanism may be adapted to a fixed cassette in the similar manner.
