Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a vending machine, a money changer,
The present invention relates to an improvement of a paper sheet handling apparatus including a conveying device for feeding a received paper sheet into a device such as a copying machine and a printing machine, and particularly, to improving a paper sheet having a width narrower than a width of a conveying path. The present invention relates to an improvement of an automatic width-adjusting device in the case of performing width-conveying on one side wall of a conveying path.

[0002]

2. Description of the Related Art An automatic vending machine, a money changing machine, a copying machine, a printing machine, or the like having a mechanism for receiving paper sheets such as paper money and bills (paper sheet handling apparatus) is provided with these devices. A conveying device is provided for guiding the paper sheets to the authenticity identifying unit, the printing unit, or the like. By the way, when inserting a paper sheet into these paper sheet handling devices by hand, the short side of the paper sheet is pushed into the conveyance path extending from the insertion opening to the inside, The width of the mouth (conveyance path) is often set to be large according to the maximum width of the paper sheets so that all the paper sheets having different widths can be received. In this case, if a narrow paper sheet is to be inserted with reference to the center, there is no guide means for restricting the widthwise position of the paper sheet, and therefore misalignment, skew or jam easily occur during the transportation process. .

This point will be explained in more detail by taking a bill handling device such as an automatic vending machine as an example. Since the size of ordinary bills (especially the length of the short side) varies depending on the denomination and the like, the width of the bill insertion slot and the conveyance path. Is designed to fit the widest bills that are expected to be accepted. However, when attempting to convey a narrow bill with a wide conveyance path at the center reference (a method of aligning the widthwise central portion of the conveyance path with the widthwise central portion of the bill), the bill becomes free to move in the width direction. When it reaches the authenticity identification portion, it is likely to be displaced from the transport reference position, and skew or jam easily occurs. As a result, indistinguishable,
Misalignment may occur, or the alignment may be deteriorated at the time of storage in a safe located after the identification unit. Further, if skew occurs in a copying machine or the like, it may cause printing failure or jam.

As a means for solving such a problem,
A method such as a display label provided in the vicinity of the insertion port of the paper sheet handling device is used to indicate that the paper sheet should be inserted by advancing to one side of the insertion port, for example, the left end, but this method It has the drawback that the proportion of users who rely on position for good or bad is too high. As a result, not all people see the displayed instruction and insert it correctly, and it becomes impossible to use, especially for children who cannot read and blind persons. In addition, the user does not always correctly push it to one side and insert it straight as instructed, and if it is inserted in a slightly skewed state, it may be sent without being corrected.

Next, FIGS. 5 (a) and 5 (b) are a plan view and a sectional view showing the structure of another conventional example.
It is equipped with a mechanism for shifting the paper sheets to one side in the width direction. That is, side plates 2 and 3 are provided upright on both sides of the conveyance path 1 in the width direction, and the width-adjusting roller 4 is inclined at a predetermined angle with respect to the conveyance direction at a position closer to one side than the center of the conveyance path 1. Are arranged. The transport path 1 is formed between the upper guide plate 5 and the lower guide plate 6, and the width-shifting roller 4 partially projects from the notch 6a formed in the lower guide plate 6 to the transport path.

In this apparatus, the inserted bill P is nipped between the width-shifting roller 4 and the upper guide plate 5 and the bill is moved toward the left side plate 2 so as to exert a drag force between the side plate 2 and the bill. The bill direction is corrected in parallel with the conveyance direction by. The photo sensor 7 detects that the bill has come close to the position of the chain line.

However, this device has the following drawbacks. That is, the conveyance force for the weak old sheet having wrinkles and creases is weak, and it is difficult for the width-adjusting roller 4 to pull it into the inside. Even if the pull-in is possible, the width cannot be adjusted. Further, the width-shifting roller has a weak pulling ability, and it is difficult to shift the posture of a banknote inserted with a large inclination in the same direction as the width-shifting roller while correcting the posture parallel to the conveying direction. Also, since the customer starts inserting the banknote in the diagonal direction from the time when the customer inserts the banknote into the insertion slot, the banknote holding force by the customer becomes an obstacle to the width adjustment until the customer releases the rear end of the banknote. Ability decreases.

Next, FIG. 6 shows another conventional example, in which the apparatus is provided with first and second belts 10 and 11 which are respectively arranged at upper and lower positions with a conveyance path interposed therebetween, and also with the conveyance path interposed. It has the width-shifting rollers 12 and 13 respectively arranged at the upper and lower positions, and both belts 10 when the paper sheets are fed in the conveying direction,
11 are brought close to each other as shown in (b) and are conveyed at the contact portion of both belts. At this time, the upper and lower width-shifting rollers 12 and 13 are in a state of being separated from each other. When the paper sheets are fed to the fixed position by the belt, both the belts are vertically separated as shown in (c), and the width-adjusting rollers 12 and 13 which have been in the separated state are used to nip the paper sheets. And send it in the width direction. When a sensor (not shown) detects that the paper sheet has approached the one side wall 2, the belt and the width-shifting roller are returned to the state of (b) and the paper sheet is conveyed in the back direction. The vertical movement of the belt and the roller is performed by using a solenoid or the like.

However, the above-mentioned device requires a complicated and expensive mechanism because it is necessary to nip the width-shifting roller while floating the belt. Furthermore, after the bill reaches the above-mentioned fixed position, it is necessary to go through the steps of turning on the solenoid, rotating the motor for driving the width-shifting roller, detecting the width-shifting, turning off the solenoid, driving the conveyor belt, etc., which slows down the processing speed.
