Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a bill handling device such as a bill changing machine and a vending machine, and more particularly to a bill handling device provided with a device for preventing the withdrawal of inserted bills.

[0002]

[Prior art]

 Generally, this type of bill handling device is equipped with a bill validator that determines the authenticity of inserted bills by a central control unit (CPU) composed of a microcomputer based on detection data. Only the banknotes that are judged to be true bills are passed. The passed banknotes are transported by the transport device and stored in the stacker. Further, in the middle of the bill discriminating device, there is provided a pull-out prevention device for preventing fraudulent intentional pull-out of inserted bills. In the pull-out prevention device, for example, a movable lever for detecting paper passage is rotatably provided in the transport passage, and the movable lever is rotated when the leading edge of the bill that has passed through the discriminating device comes into contact with the movable lever. The rotation operation of this movable lever is detected by an optical sensor such as a photocoupler. The CPU monitors the signal sent from the optical sensor by comparing it with a predetermined signal detection time corresponding to the length from the beginning to the end of the bill. If the signal detection time is the set value, it is determined that the bill is not fraudulent. However, if an attempt is made to illegally pull out a bill that has been inserted once, and a sheet material that has approximately the same width dimension as the bill is attached to the end of the bill, the movable lever will move even after the bill passes through the movable lever. Retains its operating position due to the sheet material. Therefore, the optical sensor continuously outputs a signal even when the preset signal detection time is exceeded, so the CPU detects this abnormality and recognizes that the inserted bill has been tampered with. At this time, an emergency signal is sent to stop the subsequent operation of the transport device. If necessary, an alarm device can be incorporated to generate an alarm such as an emergency alarm. In addition, as another pull-out prevention device, a claw-shaped movable lever is urged by a spring so that it can project from the transport passage, and while the bill is moving forward, the bill contacts and the movable lever is pulled into the passage. Pass on this by doing no. After passing the bills, the movable lever is projected onto the passage by the spring. Therefore, even if an illegal member such as a string or a wire attached to the end of the bill is pulled and an attempt is made to pull the bill back, the bill is caught by the movable lever protruding onto the transport passage and is blocked.

[0003]

[Problems to be solved by the device]

 However, in the above-mentioned bill handling device, since the movable lever of the pull-out prevention device is provided in the bill validator, for example, after the inserted bill passes through the movable lever, the length from the leading edge to the end of the bill is increased. Insert an incorrect member such as a sheet into the bill validator for a predetermined corresponding signal detection time, pull the movable lever into the passage, and remove the string or wire that is fastened to the end of the bill within the signal detection time. A bill may be illegally pulled out by a skillful method such as pulling the fraudulent member and pulling out the bill.

Therefore, it is an object of the present invention to provide a bill handling device capable of reliably preventing illegal removal of bills.

[0005]

[Means for Solving the Problems]

 The bill handling device according to the present invention comprises a bill validator for determining the authenticity of bills, a stacker for storing bills that have been determined to be genuine by the bill validator, and a bill validator and a stacker along a transport path. Between the transport device for transporting the banknotes and the transport path of the transport device so that the banknotes can be projected, and when the banknotes pass through the transport path, the banknotes are moved to the retracted position to pass the banknotes and the projecting position after passing the banknotes. And a pullout prevention device having a movable lever for preventing the banknotes from retracting, and a bend portion is provided at least at one position in the transport passage of the transport device, and a pullout prevention device is provided on the stacker side of the bend portion.

 An embodiment of the bill handling apparatus according to the present invention will be described below with reference to FIGS. FIG. 1 shows a side view of the apparatus of the embodiment. The main part of the device is a frame 2 that forms the outer shell of the device, a validator (banknote discriminating device) 10 that detects an element that determines the authenticity of the inserted banknote 1 and performs an appraisal based on the detection signal. It is composed of a transport device 20 that transports the bills 1 that have passed through the bill validator 10, and a stacker 50 that stores the bills 1 sent from the transport device 20.

More specifically, in FIG. 1, the validator 10 is detachably fixed to the upper part of the housing 2 and has a bill slot 11 on the front side. Is connected to the transport guide 22 of the transport device 20. The validator 10 is provided with detection means for detecting various elements for determining the authenticity of the bill being passed. Usually, the judgment factors include the paper quality, color, and printing ink components of ordinary banknotes. As one of the detection means of these various determination elements, a sensor for reading the printing pattern of the banknote is arranged in the middle of the transport passage. The pattern reading detection sensor consists of a pair of light-emitting and light-receiving elements. These elements are placed orthogonally to the transport direction, facing each other above and below the passage, and a banknote passes between both elements. That is, the banknote passing between both elements is irradiated with light to detect the intensity of the light intensity due to the print pattern, and the detection signal is sent to the central control unit (CPU) by the microcomputer, where the detection signal The authenticity of the bill is judged by performing various controls.

As shown in FIGS. 1 to 3, the carrying device 20 is housed in the frame 2 of the device frame, and is connected to the passage outlet on the validator 10 side at a connection inlet 22 a of a carrying guide 22 forming a carrying passage. It The terminal exit 22b of the transport guide 22 is connected to the cassette 51 (see FIG. 6) of the stacker 50. The transport guide 22 has two bent portions 22d and 22e. In addition, an endless conveyor belt 23 is wound around a plurality of pools 24a to 24c along the conveyor guide 22, and the banknote 1 passing through the validator 10 comes into contact with the conveyor belt 23 which is operated by frictional force. The paper is fed to the stacker 50 while being guided by the conveyance guide 22. Pressing pulleys 24d to 24f are arranged in order to facilitate the transport of the bill 1 by the transport guide 22 and the transport belt 23.

Further, the transport device 20 is provided with a motor 25 as a drive source for operating the transport belt 23, and the motor 25 is controlled by the CPU and driven in association with the operation on the validator 10 side. That is, the tip position of the bill 1 that has passed through the validator 10 is detected by a sensor such as a light emitting element such as a diode or a light receiving element, and based on the detection signal, an operation signal is sent from the CPU to the motor 25 to operate it. As shown in FIG. 2, the rotation of the motor 25 is transmitted to the pulley 25e on the shaft 25d via the toothed belt 25c wound around the gear 25b on the output shaft 25a. The belt driving pulley 24a described above is fixed on the shaft 25d, and the rotation is transmitted to the conveyor belt 23 with this pulley 24a as the driving side.

Here, as shown in FIG. 3 to FIG. 5, in the carrying device 20, the pull-out prevention device 21 which is the essence of the present invention is provided at a portion near the bent portion 22e on the terminal end outlet 22b side of the carrying guide 22. Are arranged. The pull-out prevention device 21 includes a support rod 21b supported by the frame 2 so as to intersect the transport guide 22, a movable lever 21a rotatably supported by the support rod 21b, and a pin 21c attached to the movable lever 21a. A link 21d connected together, a spring 21e for urging the link 21d, a solenoid 21f for driving the link 21d, and a sensor (detection means) 60 such as a photocoupler for detecting the operation of the link 21d are main members. It is configured. Further, bill passage detection sensors 62 and 63 such as photo couplers for detecting passage of the bill 1 are provided near the connection inlet 22a and the end outlet 22b of the conveyance guide 22, respectively. Further, although not shown, a CPU that sends a drive signal to the solenoid 21f when the detection signals from the bill passage detection sensors 62 and 63 are received is provided in the conveyance device 20.

As shown in FIGS. 4 and 5, the movable lever 21 a supported by the support rod 21 b is pulled by the spring 21 e via the pin 21 c and the link 21 d and is received in the receiving hole 22 c provided in the transport guide 22. I am involved. Therefore, when the banknote 1 that has passed through the validator 10 enters the connection entrance 22a of the transport guide 22 and the banknote passage detection sensor 62 detects the passage of the banknote 1, the solenoid 21f is driven and the link 21d causes the elasticity of the spring 21e. The movable lever 21a rotates about the support rod 21b as a fulcrum. That is, the movable lever 21a avoids rotation and does not prevent the bill 1 from passing.

As shown in FIG. 2, the intermediate gears 26a and 26b are rotatably supported on the shaft 25g of the pulley 24c on the passive side around which the conveyor belt 23 is wound. The passive gear 44 of the pushing device 30 mounted inside the cassette 51 of the stacker 50 shown in FIG. That is, when the stacker 50 is inserted and incorporated into the frame 2 of the apparatus, the passive gear 44 of the pushing device 30 on the stacker 50 side is connected to the intermediate gear 26b and meshed. The stacker 50 that stocks the sent bills in the cassette 51 is detachably attached to the frame 2 of the apparatus in FIG. The cassette 51 is formed in a rectangular box shape and can be slid in and out by engaging with guide rails provided on both inner walls of the apparatus frame 2.

A pushing device 30 is incorporated in the upper portion of the cassette 51. The pushing device 30 has a substrate 31 and a pushing plate 32 which are substantially parallel in the vertical direction. The push plate 32 can be moved toward and away from the substrate 31 in parallel by an expansion and contraction moving mechanism. That is, the two link members 33, 33 are hinged in the X-shape by the support shaft 34 at the center in the longitudinal direction. The X-shaped link members 33, 33 allow the lower push plate 32 to move toward and away from the upper substrate 31.

Next, an operation mode and an action of the bill handling apparatus having the above-mentioned configuration will be described. In use, when the stacker 50 in which the cassette 51 is empty is inserted and incorporated into the frame 2 of the apparatus, the passive gear 44 of the pushing apparatus 30 is connected to the intermediate gear 26b on the side of the conveying apparatus 20 and both teeth mesh with each other. That is, the rotary drive force of the motor 25 is directly connected to the conveying device 20 and can be transmitted to the pushing device 30. At this time, as shown in FIG. 4, the state of the pullout prevention device 21 in the transport device 20 is such that the movable lever 21a rotatably supported by the support rod 21b urges the spring 21e via the pin 21c and the link 21d. And is engaged with a receiving hole 22c provided in the conveyance guide 22.

When the banknote 1 is inserted into the validator 10, it is checked by the CPU incorporated therein based on the detection data such as the amount of transmitted light of the banknote 1. For example, it is determined whether the amount of transmitted light is within the set value range, and if it is out of the level, the inserted bill 1 is not regarded as a genuine bill, and the bill is inserted into the bill insertion slot. Put it back to the side. The banknote 1 identified as a genuine bill is guided by the transport guide 22 by the operation of the transport device 20, contacts the transport belt 23, and is sent toward the stacker 50 by this frictional force. The drive source motor 25 operates in the forward rotation direction in response to an operation signal from the CPU. During this time, the one-way clutch type transmission pulley 46 on the pushing device 30 side idles, and the normal rotation drive on the conveying device 20 side is not transmitted to the pushing device 30 side.

Here, for the banknote 1 that has passed the validator 10, when the banknote 1 that has passed the validator 10 enters the connection entrance 22 a of the transport guide 22 and the banknote passage detection sensor 62 detects the passage of the banknote 1. The detection signal is received by the CPU incorporated in the carrying device 20, and the CPU sends a drive signal to the solenoid 21f. At this time, as shown in FIG. 5, the solenoid 21f is driven and the link 21d is pulled up against the elastic force of the spring 21e. Therefore, the movable lever 21a rotates around the support rod 21b as a fulcrum, and the receiving hole of the conveyance guide 22 is received. It does not interfere with the passage of bills 1 by being separated from 22c. When the link 21d is pulled up by the solenoid 21f, the light emission of the sensor 60 is blocked and the detection signal is sent to the CPU. The CPU monitors the signal sent from the sensor 60 by comparing it with a predetermined signal detection time corresponding to the length from the front end to the end of the bill 1.

When the bill 1 is conveyed by the conveyance device 20 and the leading edge of the bill 1 is detected by the bill passage detection sensor 63, the detection signal is sent to the CPU incorporated in the conveyance device 20. At the same time, the CPU stops sending the drive signal to the solenoid 21f. At this time, since the link 21d is pulled by the biasing force of the spring 21e, the movable lever 21a comes into contact with the surface of the bill 1.

When the end of the bill 1 passes through the movable lever 21a, the movable lever 21a is engaged with the receiving hole 22c provided in the transport guide 22 so that the tip of the movable lever 21a projects onto the transport guide 22. It returns to the state shown in FIG. When attempting to pull out the bill 1 from this state, the leading end of the bill 1 comes into contact with the tip of the movable lever 21a, so that the bill 1 can be prevented from being pulled out.

As described above, in this embodiment, the bent portions 22d and 22e are provided at two locations in the transport guide 22 of the transport device 20, and the movable lever 22 is provided near the bent portion 22e on the end outlet 22b side of the transport guide 22. Since the withdrawal prevention device 21 having 21a is provided, even if an illegal member such as a sheet is inserted into the bill discriminating device 20 after the inserted bill 1 passes through the bill discriminating device 20, the movable lever 21a is moved from the conveyance guide 22. Since the banknote 1 cannot be removed, it is possible to reliably prevent illegal removal of the banknote 1. Further, even if an illegal member such as a sheet is inserted into the transport guide 22 of the transport device 20 to remove the movable lever from the transport guide 22, the transport guide 22 is bent. It is difficult to insert an unauthorized member into the transport guide 22. In this respect as well, it is possible to reliably prevent illegal removal of the bill 1. Further, bill passage detection sensors 62, 63 for detecting passage of the bill 1 are provided in the vicinity of the connection inlet 22a and the end outlet 22b of the conveyance guide 22 of the conveyance device 20, and the bill passage detection sensors 62, 63 detect the bill 1 Since the solenoid 21f that operates the movable lever 21a of the pull-out prevention device 21 when the passage is detected, the length of the bill 1 from the start end to the end is detected by the bill passage detection sensors 62 and 63, and the inserted bill is inserted. It is possible to determine whether 1 is legitimate.

The embodiment of the present invention is not limited to the above-mentioned embodiment, and various modifications can be made. For example, instead of providing the bill passage detection sensors 62 and 63 and the solenoid 21 f as in the above-described embodiment, a detection lever for detecting the contact of the leading end of the bill 1 is provided in the conveyance path so that the detection lever can be projected. The movable lever 21a may be driven by the operation of the detection lever by connecting the lever and the movable lever 21a with a wire or the like.
