Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a bill withdrawal prevention device, and more particularly to a device for preventing a criminal act in a vending machine, a money changer or the like, which pulls out the bill after inserting the bill after it is determined to be authentic. .

[0002]

[Background of device]

 Generally, in a vending machine and a money changer, a bill is inserted through an insertion slot, and when it is determined that the bill is authentic, the bill is loaded into the inside of the device and stored in a stacker. However, in the current device, if one end of the adhesive tape, piano wire, fishing line, etc. is attached to one end of the genuine bill to be inserted, the loading mechanism will stop and after the bill has been used. However, it is possible to pull out the inserted banknote from the insertion slot by pulling the adhesive tape, piano wire, fishing line, etc., and in recent years, such criminal acts have been rapidly increasing.

[0003]

[The purpose of the device]

 Therefore, the present invention was made by paying attention to the above-mentioned situation, and if foreign matter is continuously present in the inserted bill, the bill is automatically returned, and the stopper is activated even if it passes by. It is an object of the present invention to provide a bill withdrawal prevention device that cannot be pulled out by any means.

[0004]

[Means for Solving the Problems]

 In order to achieve this object, the bill withdrawal prevention device according to the present invention forms at least one or more ridges and a step portion adjacent to the ridges on the lower guide constituting the carrying path in the vicinity of the bill insertion slot. A door piece that is suspended from a support shaft that is erected on the carrying path and that has a notch that escapes the ridge, and a swing member that switches the photointerrupter on the top of the door piece. And a plurality of stopper pins that move up and down by a solenoid that is activated by a banknote position confirmation signal in the carrying path. It is characterized in that one end of the stopper is engaged with a step formed on the carrying path to serve as a stopper.

[0005]

[Action]

 With this configuration, if there is a continuous foreign matter in the bill, it will be sandwiched by the door pieces and returned without operating the photo interrupter, and if the pins or switching pieces act, the bills will not be caught there and cannot be withdrawn. is there.

【Example】

 Next, an embodiment of the present invention will be described with reference to the drawings. Fig. 1 is a side view of the main part of a mechanism that repeats returning when there are consecutive foreign objects in a bill, Fig. 2 is a front view of the same, Fig. 3 is a perspective view of a stopper pin, Fig. 4 is a plan view of an authenticity determination part, FIG. 6 is a side view of a stopper mechanism that also serves as an escrow sensor.

First, in FIG. 1 and FIG. 2, 1 is a bill insertion slot, and 2 is a carrying path. On the lower guide 3 forming the carrying path 2, two front projections 4 having a tapered front surface and a rounded head surface with a height of about 0,5 mm are formed. 4 is formed on the upper surface of the lower guide 3 adjacent to 4 with a width of 5 mm, which is cut down to the full width, and the inner surface of the step 5 is a tapered surface so that a door piece described later can rotate. Has been done.

A support shaft 6 is installed on the carrying path 2, and a pipe body 8 at the upper edge of the door piece 7 is suspended in a state where the support shaft 6 has a space. That is, the door piece 7 can freely swing back and forth around the support shaft 6, and a notch 9 and 9 is formed at the lower edge thereof to avoid the protrusion 4 and 4 of the lower guide 3 described above. There is.

Further, a swing member 10 is integrally provided on the upper surface of the pipe body 8 of the door piece 7 in a substantially linear arrangement with the door piece 7, and a photo interrupter 11 is provided so as to straddle the swing member 10. There is.

According to this device, a bill is inserted from the insertion slot 1 while pushing the door piece 7 inward, and at that time, the swing member 10 tilts forward to perform a switching action of turning on or off the photo interrupter 11. If there is no continuous foreign matter in the bill, the door piece 7 returns to the original state and the swing member 10 also returns to the proper state, but if there is any foreign matter, the cutout 9 of the door piece 7 and the lower guide protrusion. The foreign matter is caught at a point such as between the strip 4 or the lower edge of the door piece 7 and the top surface of the step 5, and the door piece 7 cannot be restored. In this state, the swing member 10 cannot be restored, so that the photo interrupter 11 detects an abnormality, and the loading mechanism is reversed to return the bill.

Reference numeral 12 shown in FIG. 3 denotes a stopper member attached to a part of the carrying path 2, particularly near the front. The stopper member 12 has a substantially T-shaped substrate 13, and a plurality of stopper pins 14, 14 ... Are provided on the lower surface of the horizontally long plate portion 13a of the substrate 13. An operating pin 15 is provided so as to project from the upper surface of the tip of the short plate portion 13b that intersects with the horizontally long plate portion 13a. The operating pin 15 is operated by a solenoid, and together with the coil spring, the stopper member 12 itself. Move up and down. That is, when a bill is conveyed and the position confirmation sensor operates, an input is made to the solenoid in conjunction with it, and when this input is made, the stopper member 12 descends and the transport path is blocked by the stopper pins 14, 14. . At this time, the lower ends of the stopper pins 14, 14 ... Are inserted into the receiving holes 17, 17 ... Formed in the authenticity determination part 16 formed in the lower guide.

In the authenticity determination part 16 in which the receiving holes 17, 17 ... Are formed, a near-infrared sensor 18 (a pair of light emission and light reception) for obtaining various waveform information and the like near the insertion port, and color and paper quality are inspected. The ultraviolet light emitting lamp tube 19 is provided with a combination of an ultraviolet sensor or a color sensor for receiving the light, and a light reflection type escrow sensor 20 for confirming the presence. The ultraviolet light emitting lamp tube 19 irradiates light to a portion corresponding to the inspection through the plurality of through holes 21, 21, ... Provided in the part 16. Although the deployment position and order of each sensor can be changed freely, it is possible to make extremely highly accurate judgments by combining them compactly and comparing the obtained data comprehensively. The distance, space, and time required for the determination are small.

On the other hand, FIG. 5 shows a stopper mechanism that also serves as an escrow sensor, and of course, if this stopper mechanism is attached, the above-mentioned escrow sensor 20 becomes unnecessary. In this mechanism, a photo interrupter 22 is provided above the carrying path, and a swing piece 23 for switching the photo interrupter 22 is pivotally supported at the upper end. The upper piece of the swing piece 23 blocks the optical path, while the lower piece engages with the step portion 24 formed on the lower guide. That is, the bill is conveyed by pushing the swing piece 23 inward, but when the swing piece 23 returns, the front edge thereof engages with the step portion 24 to serve as a stopper for pulling out the bill. Then, the conventional U-shaped swing member is not required and only one swing piece 23 is required.

The bill withdrawal prevention device according to this embodiment is configured as described above. According to the first embodiment, if foreign matter continues, it will be returned, but even if the door piece returns, it will be impossible to pull it out by placing multiple stoppers. Further, a stopper can be provided in each carrying path according to the denomination, but one kind in the present embodiment can sufficiently cope with it.

[0015]

[Effect of device]

 The bill withdrawal prevention device according to the present invention is configured as described above, and can prevent criminal activity. In particular, if it is a mechanism to return it, it is possible to prevent the destruction of the device itself.
