Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a coin batch input unit, and in particular, in a vending machine or the like, a plurality of coins can be input in a lump, and a coin mechanism that sorts and stores the inserted coins and a coin mechanism that has been paid out. The present invention relates to a coin batch input unit that is used in combination with a coin lifter that lifts up to a return opening provided adjacent to a portion into which coins are batch input.
[0002]
[Prior art]
In a vending machine or the like, the coin insertion slot is usually formed by a slot that allows one coin to enter the panel on the customer service side, and coins are inserted by inserting coins one by one into the slot. . Coins inserted from the slot are received by the coin guide and guided to the coin mechanism. In the coin mechanism, the entered coins are identified, sorted, and stored for each denomination. If change is necessary, coins of the denomination determined by the coin mechanism are paid out by the determined number and thrown out to the coin return slot.
[0003]
Coins thrown from the coin slot are dropped and stored in the coin mechanism by their own weight, and coins paid out from the coin mechanism are dropped by their own weight and thrown out to the coin return slot. For this reason, the coin insertion slot is provided at a high position, and the coin return slot is provided at a position lower than the position where the coin mechanism is located. The height difference between the coin insertion slot and the coin return slot may cause trouble depending on the person who inserts or removes the coin. Therefore, it has been proposed that the coin insertion slot and the coin return slot be at the same height position. Therefore, there has been proposed a coin transport lifter that raises coins paid out from a coin mechanism to a coin return opening set at a height position substantially equal to the coin insertion slot (Japanese Patent No. 2827470). Can be combined with a coin insertion slot, a coin return slot and a coin mechanism to realize a coin handling apparatus with good operability suitable for a vending machine or the like.
[0004]
By the way, a coin slot such as a vending machine needs to insert coins one by one into a slot. In that case, a coin must be picked one by one and accurately inserted into a narrow slot. When it is necessary to insert coins, it must be repeated for the number of coins inserted. Such a coin insertion operation is not easy especially for a person who has a handicap at a portion where a coin is picked. On the other hand, a coin lump-in device (Japanese Patent Laid-Open No. 7-200905) that can lump a plurality of coins in a lump is known.
[0005]
[Problems to be solved by the invention]
However, such a coin lump-in device has only a function of feeding a plurality of coins that have been lumped together one by one, so the coin return slot is arranged at the same height as the coin slot. There is a problem that it cannot be applied to such a coin processing device.
[0006]
The present invention has been made in view of such points, and can be applied to a coin processing device in which a coin return port and a coin insertion port are arranged at the same height position, and coin clogging is possible. An object of the present invention is to provide a coin lump-in unit that can send out coins one by one to a coin mechanism without occurrence.
[0007]
[Means for Solving the Problems]
In the present invention, in order to solve the above problem, in a coin batch loading unit capable of batch loading a plurality of coins, a coin loading tray for receiving a plurality of coins by denomination mixing, and the coin loading tray A coin hopper that retains received coins, scrapes and sends out the retained coins one by one, a return tray disposed adjacent to the coin hopper, and coins retained in the coin hopper during a return operation And a return lever that guides the return to the return tray.
[0008]
According to such a coin batch input unit, when a plurality of coins are batch-inserted into the coin input tray, the coins are retained in the coin hopper. Thereafter, the coin hopper part scrapes the coins staying inside one by one and sends them out. When the inserted coins are returned or the coin hopper is clogged, the return lever is operated so that the coins retained in the coin hopper are directly guided to the return tray placed adjacent to the coin hopper. Will be returned. Combining this coin lump-in unit with a coin mechanism and coin lifter makes it possible to apply it to a coin processing device in which the coin return slot and coin slot are located at the same height position. Since coins can be sent out one by one to the coin mechanism, it can have the same function as a device that puts in one by one.
[0009]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the embodiment of the coin lump-in unit according to the present invention will be described in detail with reference to the drawings, taking as an example the case where it is applied to a coin processing device used in a vending machine.
[0010]
FIG. 1 is a front perspective view showing an overview of a coin processing device, and FIG. 2 is a rear perspective view showing an overview of the coin processing device. The coin processing device includes a coin input tray 1 and a return tray 2 at the top thereof, and a return lever 3 is provided on the front of the coin input tray 1. These coin input tray 1, return tray 2 and return lever 3 are integrally configured as a coin collective input unit, and constitute a portion that is outside the door provided on the customer service side of the vending machine. As will be described in detail below, the coin input tray 1 has a mechanism that separates and feeds a plurality of coins that are input at a time, and a coin that is input in conjunction with the return lever 3 to the return tray 2. And a direct delivery mechanism.
[0011]
A coin mechanism 4, a coin lifter 5 and a coin shooter 6 are provided at the lower part of the coin batch input unit, and constitute a part installed inside the door of the vending machine. The coin mechanism 4 can select coins sent out from the coin insertion tray 1 and store them for each denomination, or pay out coins stored as change, when the return lever 3 is operated. A slag passage 7 is provided in parallel to bypass the coin from the coin insertion tray 1 to the coin shooter 6 disposed under the coin mechanism 4 without passing through the coin mechanism 4. The coin lifter 5 includes a conveyor belt 8, and a protrusion 9 is provided on the surface of the conveyor belt 8 at a predetermined interval. The coin is engaged with the protrusion 9 and conveyed upward. The upper exit end of the coin lifter 5 is curved to the front side and is open to the return tray 2.
[0012]
In such a coin processing apparatus, when a plurality of coins are batch-inserted into the coin input tray 1, the coins are separated one by one by a mechanism provided at the lower portion of the coin input tray 1, and the coin processing apparatus is attached. It is sent out in a posture oriented in a direction perpendicular to the surface. The sent coins are received by the coin chute 10, rotated 90 degrees while dropping by their own weight, and made parallel to the mounting surface of the coin processing device, and sent to the coin mechanism 4 in that posture. In the coin mechanism 4, the received coins are sorted and stored in denominations. When a change is necessary for the amount of money inserted after purchasing the product, a coin corresponding to the change is paid out from the coin mechanism 4 and dropped to the coin shooter 6. The coin shooter 6 feeds coins one by one to the coin lifter 5, and the coin lifter 5 transports the coins upward with the transport belt 8 in a state of engaging the protrusions 9, and throws them out to the return tray 2 from the upper outlet end. .
[0013]
In addition, when the return lever 3 is operated, the passage leading to the return tray 2 is opened for the coin input tray 1 and the coins staying in the lower portion thereof, and is directly guided to the return tray 2. The coins sent out by the mechanism provided at the lower part of the coin insertion tray 1 are dropped to the lowest coin shooter 6 when the coin chute 10 operating in conjunction with the return lever 3 contacts the slag passage 7, The coins already stored in the coin mechanism 4 are similarly linked to the return lever 3 and the coin mechanism 4 starts a return operation, is paid out from the coin mechanism 4 and dropped to the coin shooter 6. The dropped coin is sent out to the coin lifter 5 by the coin shooter 6, transported by the coin lifter 5, and thrown out to the return tray 2.
[0014]
Next, the details of each part of the coin batch input unit will be described. First, a coin insertion tray for inserting coins will be described.
FIG. 3 is a perspective view showing the coin insertion tray, and FIG. 4 is a cross-sectional view taken along the line aa of FIG. 3 showing the coin insertion tray. The coin insertion tray 1 has a large coin receiving opening on the upper surface so that a large number of coins can be received collectively. The bottom surface 11 of the coin insertion tray 1 is configured with a slope so that it can slide down smoothly with the inertial force when the inserted coin is thrown in. An insertion port 12 for inserting coins into a coin hopper provided in the is opened.
[0015]
In addition, a plurality of ribs 13 are provided on the bottom surface 11 of the coin input tray 1 so as to face the input port 12 along the slope. The rib 13 reduces the contact area between the bottom surface 11 and the coin so that the coins wet with water do not stick to the bottom surface 11 when the coin slides along the bottom surface.
[0016]
Further, a guide wall 14 for guiding the inserted coins to the insertion slot 12 is provided on the bottom surface 11 of the coin insertion tray 1. The guide wall 14 is for limiting the direction in which the inserted coins are guided toward the insertion slot 12 to one direction. That is, when coins are concentrated and gathered from three sides toward the insertion slot 12, it is difficult for the coins that have advanced toward the insertion slot 12 to be sandwiched between the coins coming from both sides and to move toward the insertion slot 12. Furthermore, there is a tendency that coins are piled up on top of it and a mountain is formed, which tends to clog in front of the insertion port 12. Therefore, by providing the guide wall 14, no coin flows from the lateral direction toward the insertion slot 12, and the coin can be smoothly guided to the insertion slot 12. Even if clogging occurs, the accumulated coins are out of balance by lightly striking the accumulated coins with the fingertips from above, and the flow of coins to the slot 12 can be easily caused.
[0017]
Next, the coin hopper part arrange | positioned at the lower part of the coin insertion tray 1 is demonstrated.
FIG. 5 is a partially broken perspective view showing a schematic operation of the coin hopper, and FIG. 6 is a cross-sectional view taken along the line bb of FIG. 5 showing the coin hopper and the return tray. First, as shown in FIG. 6, the coin hopper section drives the hopper base 21 provided in an inclined state, a disc 22 provided rotatably on the hopper base 21, and the disc 22. The gear box 23 and the motor 24, an inclined wall 25 disposed obliquely facing the hopper base 21, and a dust flapper 26 constituting a part of the inclined wall 25 are configured.
[0018]
The hopper base 21 and the disc 22, the inclined wall 25 and the dust flapper 26 constitute a hopper port for receiving coins inserted from the input port 12 of the coin input tray 1, and the lower portion of the hopper base 21 is a return tray. A coin chute 27 that communicates with the two openings 2a is formed.
[0019]
The dust flapper 26 is provided so as to be swingable about a shaft 28, and a spring 29 for biasing the dust flapper 26 toward the hopper base 21 is provided on the shaft 28. This dust flapper 26 is also provided with a rod 30 extending downward in the plane of FIG. 6 and is engaged with the return lever 3 on the back side of the unit. When the return lever 3 is in operation, it is swung to the position shown by the two-dot chain line against the urging force of the spring 29 to open the bottom of the hopper mouth.
[0020]
As shown in FIG. 5, the hopper base 21 further includes a coin rail 31 that is disposed close to the upper surface of the disk 22 and extends obliquely downward from the vicinity of the center of rotation of the disk 22 toward the back side of the unit. It is fixed. The lower side end face of the coin rail 31 is in communication with the receiving port of the coin chute 10 for inserting coins into the coin mechanism 4. The coin rail 31 has an upper thickness reduced so that two or more coins do not get on the upper end face. Further, on the surface of the disk 22, two metal claws 32 are linearly provided in the radial direction of the disk 22.
[0021]
In FIG. 5, an insertion port 15 connected to the return tray 2 is opened on the back side of the return tray 2, and a throwing port of the coin lifter 5 is connected to the insertion port 15.
[0022]
Here, the schematic operation of the coin hopper configured as described above will be described. First, when coins are inserted into the coin input tray 1, the coins fall through the input port 12, and are input into the hopper port of the coin hopper portion and stay there. When the insertion of coins into the coin insertion tray 1 is detected, the motor 24 operates and the disk 22 is rotated. As a result, one of the coins staying at the hopper mouth moves upward with the rotation of the disk 22 in a state where the coin is engaged with the claw 32. When the coin passes the apex, the coin is detached from the claw 32. It falls by its own weight, and falls on a coin rail 31 arranged so as to block the coin drop passage below it. The coins that have fallen on the coin rail 31 roll down along the upper side of the coin rail 31 and are put into the receiving port of the coin chute 10. Thereafter, the claw 32 passes through the coin rail 31 through a groove recessed in the surface of the coin rail 31 on the disk 22 side.
[0023]
In this way, the coin hopper unit picks up the coins that have been thrown into the coin throwing tray 1 one by one and throws them out one by one on the coin chute 10.
When the free end of the return lever 3 is pressed while coins are staying at the hopper mouth, the link mechanism interlocked with the return lever 3 moves the rod 30 fixed to the dust flapper 26, and the bottom of the hopper mouth Is released. Thereby, the coin staying at the hopper mouth falls to the coin chute 27 and is returned to the return tray 2 through the opening 2a. This mechanism can remove foreign matter to the return tray 2 by operating the return lever 3 even when foreign matter enters the coin hopper.
[0024]
Next, a mechanism in which the coin hopper separates a plurality of coins one by one and carries them to the coin rail 31 will be described in more detail.
FIG. 7 is a cross-sectional view taken along the line cc of FIG. 5 showing the coin hopper. First, a coin insertion detection sensor that detects that a coin has been inserted into the coin insertion tray 1 is provided. As the coin insertion detection sensor, in the illustrated example, a magnetic sensor 35 provided on the lower surface of the coin insertion tray 1 and a passage through which a coin on the downstream side of the insertion port 12 of the coin insertion tray 1 passes are provided. An optical sensor 36 is shown. Here, both the magnetic sensor 35 and the optical sensor 36 are shown, but since these functions are the same, either one may be actually used. The magnetic sensor 35 detects a change in the magnetic field generated by the close proximity of the inserted coins and determines that the coins have been inserted. The optical sensor 36 determines that a coin has been inserted when light is blocked by the coin between the light emitting element and the light receiving element. In this way, the motor 24 is operated when the insertion of the coin into the coin insertion tray 1 is detected, and the rotation drive of the disk 22 is started.
[0025]
In addition, since the optical sensor 36 can detect the currency of the coin in the insertion slot 12 of the coin insertion tray 1, it can count the approximate number of coins inserted. By using this count number, the stop time of the motor 24 driving the disk 22 can be predicted. Normally, the motor 24 is stopped after a predetermined time after the coins are inserted, or after a predetermined time since the last insertion of the coins. It is possible to stop the motor 24 in a time that is surely shorter than the time during which it is likely to have been thrown into the coin chute 10.
[0026]
A micro switch 37 is provided beside the hopper base 21. The micro switch 37 is normally energized by the dust flapper 26, and the energization is released when the dust flapper 26 operates. Since the dust flapper 26 operates in conjunction with the return lever 3, the microswitch 37 electrically detects the operation of the return lever 3. This detection is used for controlling the operation of a shutter, which will be described later, for closing the insertion slot 12 of the coin insertion tray 1 and preventing the insertion into the coin batch input unit.
[0027]
The circular plate 22 has a plurality of arc-shaped ribs 38 arranged concentrically on the surface thereof. These ribs 38 are provided to prevent such coins from sticking to the surface of the disc 22 when the coins inserted into the hopper mouth are wet.
[0028]
FIG. 8 is a partially broken perspective view of a hopper base to which a disk is attached. The coin put into the hopper mouth is engaged with the claw 32 attached to the disk 22 by the rotation of the disk 22 and moves upward. At that time, the coin is engaged with the claw 32 as shown in the figure. In some cases, the coins 41 that have been used have the same action as the claws 32 and are carried together with the first coin 41 in a state where the second coin 42 is on the edge of the coin 41. As described above, when the two coins 41 and 42 are carried in series, so-called continuous throwing occurs in which two coins are continuously thrown into the coin mechanism 4 within a short time. If there is continuous throwing, there is a high possibility that clogging will occur at the receptacle of the coin mechanism 4. Therefore, in order to ensure that coins are fed one by one, the disc 22 is provided with a coin kick mechanism that ensures that only one coin is carried by the claw 32.
[0029]
This coin kick mechanism is provided at a position away from the claw 32 of the disc 22 by a predetermined distance, and an oval opening 43 best shown in FIG. It comprises a kick spring 44 that can project to the side where the coins stay, and a cam 45 that protrudes from the surface of the hopper base 21 on the back side of the disc 22. The claw 32 and the opening 43 are in a positional relationship separated by a distance slightly longer than the diameter of the largest coin. Further, the cam 45 is provided at two positions, the position shown in the figure and the position where the kick spring 44 is shown.
[0030]
When the disc 22 rotates and reaches a predetermined rotational position, the kick spring 44 is pushed out from the back side by the cam 45 and protrudes from the opening 43. Here, when two coins are continuously engaged with the claw 32, the second coin 42 is kicked into the space where the coins are retained by the projecting kick spring 44 and carried by the claw 32. Is only the first coin 41 engaged with the claw 32, and only one coin is always carried to the coin rail 31 for each rotation of the disk 22.
[0031]
9 is a cross-sectional view taken along the line dd in FIG. 7 showing a state when the coin kick mechanism is not operating, and FIG. 10 is a cross-sectional view taken along the line dd in FIG. 7 showing the state during operation of the coin kick mechanism. . One end of the kick spring 44 is fixed to the back surface of the disk 22. At this time, the fixed end of the kick spring 44 to the disk 22 may be fixed so that the free end of the kick spring 44 is swung on the hopper base 21 by its own weight so as to be swingable in the vertical direction in the figure. The end may be fixed so as to be biased toward the hopper base 21 by a spring action.
[0032]
Here, when the coin kick mechanism is not in operation, the kick spring 44 is in a state of entering from the surface of the disk 22 as shown in FIG. At this time, the coins 41 and 42 are allowed to move by the disc 22 in a state where two coins are connected. When the disk 22 is rotating and its opening 43 reaches a position where the cam 45 of the hopper base 21 is located, the kick spring 44 rides on the cam 45 as shown in FIG. The portion protrudes upward in the figure through the opening 43. As a result, the second coin 42 at the position of the opening 43 is kicked upward by the kick spring 44, and the first coin 41 is the only coin engaged by the claw 32.
[0033]
In this way, the protrusion / embedding of the kick spring 44 with respect to the opening 43 is periodically and repeatedly executed by the cam 45 of the hopper base 21 to ensure that only one coin is thrown out from the coin hopper. it can. By providing this coin kick mechanism at a position that is slightly longer than the length of the diameter of the largest coin from the position where the claw 32 is located, what is thrown into this coin hopper has a larger shape than the coin. In this case, even if it is engaged with the claw 32 and is carried to the coin rail 31, it is kicked out by the coin kick mechanism and dropped from the claw 32, so that a foreign object larger than the coin is not carried to the coin rail 31. . That is, this coin kick mechanism also has a function of selecting the outer diameter of coins.
[0034]
11 is a perspective view of a hopper base showing another embodiment of the coin kick mechanism, FIG. 12 is a cross-sectional view taken along the line ee of FIG. 11 showing a state when the coin kick mechanism is not operating, and FIG. 13 is a coin kick mechanism. It is the ee arrow sectional drawing of FIG. 11 which shows the state at the time of operation | movement. An opening 46 is provided at a position away from the claw 32 of the disk 22 by a predetermined distance, and a kick pin 47 and a spring 48 are accommodated in the opening 46. The spring 48 urges the kick pin 47 downward in the figure so as to embed the kick pin 47 in the opening 46.
[0035]
Here, when the coin kick mechanism is not in operation, the kick pin 47 is in a state where it enters from the surface of the disk 22 as shown in FIG. 12, and the two coins 41 and 42 are connected. Movement by the disc 22 is allowed. When the disk 22 is rotating and its opening 46 reaches a position where the cam 45 of the hopper base 21 is located, the lower end of the kick pin 47 rides on the cam 45 as shown in FIG. The upper end protrudes upward in the figure through the opening 46. As a result, the second coin 42 at the position of the opening 46 is kicked upward by the kick pin 47 in the drawing.
[0036]
Thus, the protrusion operation of the kick pin 47 from the opening 46 is periodically repeated by the cam 45 of the hopper base 21 so that the coins are guided to the coin rail one by one, and the coins are surely one by one. It becomes possible to throw out from the coin hopper.
[0037]
Next, a mechanism for improving the coin acceptance rate in the coin hopper will be described.
FIG. 14 is a plan view of a coin batch insertion unit showing a state in which a coin insertion tray is removed in order to explain the coin acceptance rate, and FIG. 15 is a plan view showing a coin hopper portion with improved coin acceptance rate. When a coin falls from the coin throwing tray 1 to the coin hopper, it falls into a space constituted by the disc 22 and the inclined wall 25 and the dust flapper 26 disposed opposite to the disc 22, but the coin throwing tray. Depending on how the coins fall from 1, the coins may ride on the coin rail 31 and the inclined wall 25 and become a bridge as shown in FIG. This state occurs with a coin having a large outer diameter. For a coin with a small outer diameter, the coin may ride on either the coin rail 31 or the inclined wall 25, but not both. In such a case, the coin rail 31 and the inclined wall 25 do not move even if the disk 22 rotates due to coin insertion, or even if the dust flapper 26 moves by operating the return lever 3, so Coins that have been lost are not sent out from the coin hopper. That is, the inserted coin has not been accepted by the coin hopper.
[0038]
Therefore, as shown in FIG. 15, a coin slide 51 is provided at a position where the coin falls from the coin loading tray 1. The coin slide 51 is arranged so as to partially block the coin dropping path from the coin loading tray 1 to the coin hopper, and guides the coins that have fallen to a position where there is no coin rail 31. The coin slide 51 is inclined downward toward the center of the hopper mouth, and the length in the inclined direction is such that the tip of the coin receives the center of gravity of the falling coin and does not stop there. The dimensions are determined. Thereby, when coins fall in the coin hopper, the inserted coins are not in a bridge state, and all the inserted coins can be received.
[0039]
Next, another mechanism linked to the operation of the return lever 3 will be described.
FIG. 16 is a rear perspective view of the coin collective loading unit showing the interlocking mechanism of the return lever. As shown in FIG. 1, the return lever 3 is held in a horizontal direction in a normal standby state, and is pivotally supported so that it can be rotated until it comes into contact with the stopper 3a.
[0040]
The shaft of the return lever 3 is connected to a shaft 55 extending in the rear direction. An arm 56 bent in a U-shape is fixed to the shaft 55, and an ellipse opening 57 elongated in the longitudinal direction is formed on the free end side of the arm 56. In the opening 57, the tip of the rod 30 (see FIG. 6) fixed to the dust flapper 26 is loosely inserted. Here, when the free end of the return lever 3 is pushed down, the arm 56 fixed to the shaft 55 is also rotated in the same direction, that is, in the counterclockwise direction of the drawing shown by the arrow 58, and in conjunction with this, the rod 30. Is moved, and the dust flapper 26 fixed to the rod 30 is swung around the shaft 28, whereby the bottom of the coin hopper is opened. As a result, the coins retained in the coin hopper are thrown out to the return tray 2 through the coin chute 27.
[0041]
Further, another arm 59 is fixed to the shaft 55. This arm 59 is associated with the return operation lever 60 of the coin mechanism 4. The return operation lever 60 is pivotally supported by the coin mechanism 4 so as to be rotatable, and is urged counterclockwise in the figure by a spring 61 provided around the axis, so that the coin mechanism 4 is normally moved. Hold in operating position. At this time, the return operation lever 60 is engaged with the arm 59. Here, when the free end of the return lever 3 is pushed down, the arm 59 fixed to the shaft 55 rotates in the counterclockwise direction in the figure, and the return operation lever 60 is resisted against the urging force of the spring 61. Turn clockwise in the figure. By the rotation of the return operation lever 60, the return mechanism of the coin mechanism 4 is operated to perform a return operation.
[0042]
In this way, the return lever 3 is operated to return the coins retained in the coin hopper and return the coins stored in the coin mechanism 4, while closing the dust flapper 26 at the coin hopper. The arms 56 and 59 are urged by the spring 29 and the spring 61 holding the return operation lever 60 in the normal operation position of the coin mechanism 4, respectively. The
[0043]
FIG. 17 is a rear perspective view of the shutter mechanism provided at the insertion slot of the coin insertion tray. The shutter mechanism is a shutter 65 provided so as to be movable up and down so as to close and retract with respect to the insertion slot 12 of the coin insertion tray 1, a shutter lever 66, and the shutter 65 is driven in the vertical direction via the shutter lever 66. And a solenoid 67. The shutter lever 66 has an opening 68 at one end thereof, a notch 69 at the other end, and is supported so as to be rotatable about a shaft 70. A projection 71 of the shutter 65 is loosely inserted into the opening 68 of the shutter lever 66, and a plunger 72 of a solenoid 67 is engaged with the notch 69.
[0044]
Here, when the power of the vending machine is not turned on, the solenoid 67 is de-energized, and the shutter lever 66 is lowered on the side where the opening 68 is located as shown by the solid line in the figure. 65 descends and closes the slot 12 of the coin tray 1. When the power of the vending machine is turned on, the solenoid 67 is excited and its plunger 72 attracts the notch 69 of the shutter lever 66, whereby the opening 68 of the shutter lever 66 is indicated by a two-dot chain line. Thus, ascending, the shutter 65 is raised accordingly, and the insertion slot 12 of the coin insertion tray 1 is opened. The solenoid 67 is also deactivated when the dust flapper 26 is operated when the return lever 3 is operated and the urging of the dust flapper 26 to the micro switch 37 is released. As in the case where the power is not turned on, the shutter 65 is lowered and the insertion slot 12 of the coin insertion tray 1 is closed.
[0045]
Thus, the shutter 65 always keeps the opening 12 open in the standby state when the power is turned on, and closes the opening 12 when a power failure occurs or when a return operation is performed. Coins cannot be inserted into the coin batch input unit.
[0046]
【The invention's effect】
As described above, in the present invention, a plurality of coins received in a lump by a coin insertion tray are separated one by one by a coin hopper and are put into a coin mechanism provided at the bottom. Thereby, a barrier-free coin batch input unit can be provided. Moreover, by arranging the return tray adjacent to the coin hopper, the coin batch input unit can be applied to a coin processing device in which the coin return slot and the coin slot are arranged at the same height position.
