The discharge mechanism of the present invention It is provided in the transfer means D is.
[0007]
The discharge mechanism a will be described with reference to FIG. 2. From the feed roller 1, a guide plate 4 having an arc guide portion 2 whose upper portion approaches along the outer peripheral surface of the feed roller 1 and a flat guide portion 3 following the arc guide portion 2. The guide plate 4 of the conveying means D is configured such that a bearing portion 5 provided on the back surface of the lower end portion is pivotally supported by a shaft 8 on a bearing 7 provided on an inner frame 6 of the main body casing A and can be brought into contact with and separated from the feed roller. ing. Further, a bifurcated bearing 9 is suspended from the back surface of the flat guide portion 3 near the arc guide portion 2. A horizontal shaft 10 is attached to the bearing 9, and the flat guide portion 3 between the bearing 9 and the bearing portion 5 is supported. As shown in FIG. 3, a concave portion 11 having a required width is provided on the surface side, and a knob guide groove 12 is provided at the center of the concave portion 11 in the width direction across the upper and lower ends of the concave portion 11. Further, a guide plate 4 is formed by penetrating a lateral groove 13 having a required width (width capable of inserting a thickness of a 10-yen coin) communicating with the knob guide groove 12 from the left and right ends.
On the other hand, the horizontal portion 15 of the slider 17 having an inverted T shape is slid between the horizontal portion 15 and the vertical portion 16 on the inclined guide portion 14 substantially parallel to the flat guide portion 3 of the inner frame 6 of the main body casing A. The horizontal shaft 10 is slidably guided in a swinging guide groove 18 that is placed freely and penetrates from the upper side to the lower side in the vertical center of the vertical part 16. The upper part of the vertical part 16 has a T-shaped guide part 19 projecting on the upper surface side so as to be in contact with and away from the back surface of the guide plate 4, and the lower part of the vertical part 16 projects on the upper surface side with the same width dimension. The knob 20 is slidably guided in the knob guide groove 12. In the operation state of FIG. 2, the protruding end of the knob 20 protrudes from the bottom surface of the recess 11, but the knob 20 is formed with a dimension that does not protrude from the surface of the flat guide portion 3. One end of a coil spring 21 having the other end engaged with the inner frame 6 is engaged with the lower end of the vertical portion 16, and the elastic force of the coil spring 21 is biased to the guide plate 4 via the horizontal shaft 10. A gap 22 suitable for conveying paper sheets is formed between the outer peripheral surface of the feed roller 1 and the surface of the arc guide portion 2 of the guide plate 4.
[0008]
In the normal operation, the discharge mechanism a by the guide plate 4 and the slider 17 in the conveying means D causes the descending end of the slider 17 to be transverse to the upper end of the swing guide groove 18 by the elastic force of the coil spring 21. At the same time, the elastic force tends to cause the guide plate 4 to rotate counterclockwise about the shaft 8 while the horizontal portion 15 of the slider 17 is inclined to the inclined guide portion 14 of the inner frame 6. Therefore, the gap 22 is kept constant and the sheets are conveyed.
[0009]
Next, let ’s take a look at the case where a paper jam occurs due to the loading of a weakened paper sheet or a bad paper sheet.
Since the paper jam occurs in the gap 22, the operator opens the front cover 23, puts his finger on the knob 20 of the slider 17, and resists the elastic force of the coil spring 21 as shown in FIG. 4. When is pushed up, the slider 17 is guided and pushed up by the inclined guide portion 14. At this time, since the horizontal shaft 10 guided by the swing guide groove 18 is guided by the descending portion 24 of the swing guide groove 18, the guide plate 4 slightly rotates counterclockwise around the shaft 8, and the horizontal groove is at the upper end of the push-up. A coin 25 indicated by an imaginary line is inserted into 13 and the guide plate 4 is opened. Since the gap 22 is widened, the jammed paper sheet 26 is easily pulled out from the operation side in the unloading direction, and the paper jam is eliminated.
When the paper jam is eliminated, when the coin 25 is removed from the lateral groove 13, the slider 17 is pulled down by the coil spring 21. At the same time, the horizontal shaft 10 is pushed up by the swing guide groove 18, and the guide plate 4 is centered on the shaft 8. When the horizontal shaft 10 is slightly rotated to the right and the horizontal shaft 10 is engaged with the upper end of the swing guide groove 18, the elastic force of the coil spring 21 does not act on the clockwise rotation of the guide plate 4. Retained. The front cover 23 is closed to complete the paper sheet removing operation.
[0010]
【The invention's effect】
According to the discharge mechanism of the present invention, even if a paper jam occurs, the operator can remove the jammed paper sheet by operating the processing device from the same direction as usual, so the paper sheet removal operation becomes easy. In addition, since the opening and closing angle of the guide plate necessary for removing the jammed paper sheet can be kept small, the degree of freedom in designing the determination sensor means and the related mechanism to be stored in the back portion can be increased, and the space in the back portion is not limited. It is possible to enhance the functionality of the paper sheet processing apparatus itself.
