せ給紙を完了する。1. When the paper sheets 3 are loaded on the support plate 2, the support plate 2 is moved to υ1', 2, 41' by the position adjustment part (not shown).
1 and the filter paper sheets 3A are placed in a predetermined position. When the sheet is fed from the outside to the paper feeder 11 (not shown), the controller 11j controls the cam 13 so that the maximum outer circumferential edge of the radius of the cam 13 still touches the roller 11. Zl, where the cam 13 presses the roller 11 against the elastic force of the tension coil spring 12, and the 21st cylinder IK.
As shown, the frame swings counterclockwise about the shaft 10A as a fulcrum. Conveyor belt 5 wrapped around drive pulley 6
The lower end of the lower end contacts the paper leaf 3A of the uppermost part A) 7. The drive pulley 6 rotates in synchronization with the movement of the cam 13σ)I111, and the conveyor belt 5 on the side of the drive pulley 6 moves the second sheet of paper 3A.
+LJ is applied to the friction portion 4A of the conveyor plate 4. When this paper sheet 3A is guided to the friction part 4A of the conveyance plate 4, the cam 13 rotates toward the minimum 11 minutes of the outer Y radius, and the elastic force of the tension coil spring 12 causes the frame 8 to move toward the axis 10A. 'ft As a fulcrum, it gradually tilts to 8 torso. The drive wheel 11 side of the conveyor belt 5 rises and releases the pressure contact with the sheet 3 to prevent duplicate conveyance or jamming. In addition, the driving ceiling side of the conveyor belt 5 is lowered and the conveyor plate 4
The friction part 4A is fully pressed. The overlapping paper sheets 3 are separated from the uppermost sheet 3A at this friction part 4A, and the uppermost sheet 3 is separated from the uppermost sheet 3A.
Only A is guided to the conveyance roller 14 along the conveyance play (4). As shown in FIG. 1, the frame 8 maintains the state in which the drive ceiling side of the conveyor belt 5 is pressed against the conveyor plate 4 for a while,
It is held under three pressures and guided along the conveyance plate 4 to the detection sensor 15. When the paper sheet 3A passes through the detection sensor v15, the detection sensor 15d detects that the paper sheet 3A has been fed and sends a signal to the control section to stop the power source of the drive pulleys 6 and 7 and complete the paper feeding.
なお、駆動プーリ6.7.プーリ9,10はギアであっ
ても良い。Note that the drive pulley 6.7. The pulleys 9 and 10 may be gears.
以上簡明したように本発明を用いれば紙厚にかかわらず
止′複搬送やジャムが防止されその効果は大である。As explained above, if the present invention is used, double conveyance and jams can be prevented regardless of paper thickness, and the effect is great.
