Description

[Detailed Description of the Invention] (Industrial Field of Application) The present invention relates to a banknote validator that has a simple structure and can reliably identify banknotes.

(Prior Art) Bill validators are often used in ticket vending machines, automatic cigarette vending machines, and the like. Its structure is that a banknote insertion slot is provided on the front panel of the case, and while the banknotes inserted through this slot are sent to the banknote storage section (accommodation box), printing ink etc. is removed from genuine banknotes (regular banknotes). ) or not. Since this identification is performed by pressing a magnetic head against the banknote, it must be received from the side of the banknote opposite to the magnetic head (or the back side when the magnetic head is in contact with the front side of the banknote). For this reason, in the past, a structure was used in which a roller was provided opposite the magnetic head, and this roller was pressed against the magnetic head by a spring.

(Problem that the invention aims to solve) In the case of the conventional structure as described above, it is effective to reliably press the banknotes toward the magnetic head side, but the rotating roller has a spring that applies a pressing force toward the magnetic head side. This resulted in a complicated structure, increased assembly man-hours, and increased costs. The present invention was developed in view of this point.

(Means for Solving the Problem) As a means for solving the above-mentioned problem, the present invention is a means for solving the above-mentioned problem. A box part is formed, and a resin piece with a semicircular lower part and a square upper part is provided in the box part, a shaft is inserted into the piece, and the piece is pushed out from the box part by a spring. The structure is such that the semicircular part of the piece faces the magnetic head by biasing it in the protruding direction and attaching it.

(Function) With this configuration, the resin piece with appropriate sliding properties guides the banknote well with its curved surface (on the magnetic head side), making it easier to use than conventional rollers. The structure helps the banknotes come into contact with the magnetic head and move toward the ejection port.

(Embodiment) Next, an embodiment of the present invention will be described with reference to FIG. 1. Reference numeral 1 is a frame, and 2 is a banknote insertion slot forming a part of the frame. This frame 1 is attached to the inside of the front panel of the case with the banknote insertion slot 2 facing toward you. A banknote discharge port is provided at the rear end of the frame 1, but is not shown. Two shaft mounting plates 3 are provided on the frame 1 to face each other, and two shafts 4 are attached to both ends of the shaft mounting plates 3 by inserting their ends into holes 5. The shaft 4 is made of a spring material such as a stainless steel rod, and is biased by setting the position of the hole 5 and other factors so as to apply a downward force as shown in the figure to a roller 6 attached to the middle part of the shaft 4. There is. Reference numeral 7 denotes a motor that is provided inside the frame 1 and provides driving force to a roller (not shown) via a belt.

Three box portions 8 are provided side by side between the two shafts 4, 4 of the frame 1. Inside this box part 8, as shown in FIG.
It is biased in the direction of protruding from the box part 8 by the holder. A shaft 11 is inserted through the piece 9, and is engaged with a hole 12 provided in the box portion 8 to prevent it from falling off. Piece 9 is frame 1
It faces the magnetic head 13 attached to the piece 9 and is designed to maintain appropriate pressure and slipperiness against the banknotes passing between the piece 9 and the magnetic head 13.

This device configured as described above operates as follows. In this device, banknotes are inserted through the insertion slot, and the banknotes are transferred by a roller 6 and a belt that is stretched around a roller (not shown) facing the roller 6, and in the process, the banknotes are inserted by a magnetic head (not shown). Identify whether the bill is genuine or not.
There is no difference in the operation of identification itself from the conventional one. A piece 9 that holds the banknote from both the front and back sides to identify the banknote, and a magnetic head provided opposite this piece 9, use the elastic force of a spring 10 to hold the banknote with appropriate pressure. Since the banknotes are clamped, even if the banknotes have some wrinkles or creases, there will be no problem in identifying the banknotes.

(Effects of the Invention) Since the present invention is configured as described above, the conventional structure, which was complicated because the rotating roller was held down by a spring, can be simplified. By using resin for the bridge and forming the magnetic head side in a semicircular shape, banknotes can be guided to the ejection port side with appropriate pressing force and slipperiness. Since the configuration is simple, the number of man-hours required during production can be reduced, and costs can also be reduced.
