Description

  The present invention is mounted on a vending machine, a money changer, or the like, detects a banknote inserted from a banknote insertion slot by an optical sensor provided in the banknote passage, and conveys the banknote into the apparatus in response to the detection. The present invention relates to a bill validator.

  In recent years, bill recognition devices have been incorporated into devices intended for automatic commerce such as vending machines, ticket vending machines, or money changers so that payments can be made not only with coins but also with bills. ing. FIG. 8 shows a conventional banknote recognition apparatus 1 incorporated in a vending machine or the like. These banknote recognition apparatuses usually include banknote insertion detection sensor means for detecting insertion of a banknote when it is inserted from a banknote insertion slot, and respond to a detection signal from the banknote insertion detection sensor means along the banknote path. It is comprised so that the banknote conveyance means arrange | positioned may be driven and the inserted banknote may be conveyed into the inside of the banknote identification device in which a banknote identification means etc. are arrange | positioned. This bill insertion detection sensor means is usually constituted by a transmission type or reflection type optical sensor, the light emitting element outputs, for example, a 60 Hz light pulse, and the light receiving element counts the light pulses from the light emitting element. is doing. Then, the previous received light amount value is held, the previous value is compared with the next received light amount value, and the insertion of banknotes is detected when the value is lower than the previous value by a certain level or more.

  For this reason, banknote recognition devices incorporated in vending machines installed outdoors are always exposed to exhaust gases and dust from automobiles, and only the surroundings of vending machines are frequently illuminated at night. Therefore, it is easy for small insects to gather. In this case, exhaust gas, dust, and insects entering from the bill insertion slot adhere to the light emitting element or the light receiving element used in the bill insertion detection sensor means and reduce their sensitivity.

    Japanese Patent Laid-Open No. 2000-149122 which deals with the insertion slot mechanism of the banknote recognition apparatus is one that tackles the above problem. The bill insertion slot mechanism is generally configured as shown in FIG. The insertion slot cover 2 is axially coupled so as to be rotatable in the front side as viewed from the customer purchasing the product, that is, in the direction indicated by X in FIG. This is done by manually rotating the insertion slot cover 2 with the hand and inserting the banknote with the other hand.

Japanese Unexamined Patent Publication No. 2000-149122

  However, in the banknote insertion slot mechanism disclosed in Japanese Patent Laid-Open No. 2000-149122, when inserting a banknote, the customer manually operates the insertion slot cover 2 with one hand and inserts the banknote with the other hand. Such an operation inconveniences the customer, and is particularly inconvenient for a customer such as a disabled person whose hands are not free. On the other hand, for a vending machine user, a specific customer may intentionally destroy the insertion slot cover, which is inconvenient in that repairs are required each time. Furthermore, since the returned banknote is pushed by opening the insertion slot cover, the customer's operation is unnecessary, but when a banknote with insufficient strength is returned, the insertion slot There is a problem that the cover 2 cannot be pushed open, and the bills are jammed in the bill passage near the bill insertion slot. In addition, there is a problem that the insertion port cover 2 is restricted in terms of location when installed indoors or the like from the structural point of view of opening and closing in the direction indicated by X. Furthermore, since the insertion opening cover 2 is transparent to disturbance light, there is a problem that an internal optical sensor malfunctions due to the influence of disturbance light. In particular, automobile headlights, lightning flashes, etc., instantaneously affect the bill insertion detection sensor means with high intensity, so even if such an insertion slot cover is provided, the influence can be eliminated. It was difficult.

  SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a banknote identification device that prevents disturbance light, exhaust gas, dust, insects and the like from entering a banknote insertion slot and prevents malfunction of the banknote insertion detection sensor means.

  In order to solve the above-mentioned problems, the banknote identification device of the present invention is arranged along a banknote passage connected to a banknote insertion slot, and an inserted banknote detection sensor means that detects a banknote inserted from the banknote insertion slot by light. And a banking passage provided by upstream of the banknote insertion detection sensor means in the banknote passage, shielding the ambient light entering from the banknote insertion port by shielding the banknote passage, and applying an external force to the shielding means. Urging means for urging the shielding means in a direction to shield the urging means, and driving means for retreating the shielding means from the bill passage by applying to the shielding means an external force acting in a direction opposite to the external force applied to the shielding means by the urging means. It is characterized by including.

Therefore, it is easy to use and it is possible to prevent mischief that intentionally destroys the shielding means. Furthermore, it is possible to reliably block disturbance light until the bill reaches the bill insertion sensor.

  According to the further aspect of this invention, in said banknote identification device of this invention, a banknote accommodating part which is provided in the downstream end of a banknote path | pass and accumulate | stores a banknote, and presses a banknote toward a banknote accommodating part from a banknote path | route. Stacking means for driving, the driving means drives the stacking means and the shielding means, and the driving means drives the rotational movement of the single motor and the shaft of the single motor along the longitudinal direction of the bill validator. Power transmission means for driving the stack means, the shutter means and the shielding means, and the power transmission means is provided at one end of the predetermined range where the power transmission means performs the slide movement. When the power transmission means is positioned at the other end of a predetermined range in which only the stack means is driven to press the bills toward the bill storage portion and the power transmission means performs a sliding motion. And the shutter means are opened to open the bill passage, and when the power transmission means is positioned approximately at the center of a predetermined range in which the power transmission means performs a sliding motion, all of the stack means, the shutter means, and the shielding means It is a banknote identification apparatus which has a non-operation area | region which is not driven.

  According to the banknote identification device described above, the stack unit and the shielding unit can be driven by a single driving unit, and the shielding unit is added to the conventional banknote processing apparatus, thereby suppressing cost and enlargement of the apparatus. Is possible. That is, according to the above configuration, the mechanical link between the stack cam and the driving member has a configuration in which the shielding unit and the shutter unit, or the non-operating area where the stack unit does not operate, and the banking passage 3 is configured by the shielding unit and the shutter unit. It is possible to ensure that the two parts communicate with each other and the end of the banknote passage is not closed by the stacking means by the stacking means. It can be used as an area for temporary holding. This significantly suppresses the enlargement of the banknote recognition device.

  FIG. 1 shows a cross-sectional view as viewed from the side of a banknote recognition apparatus 100 according to the present invention. The banknote identification device 100 of the present invention is attached to the upper chute 101, the banknote accommodating part 102, the main body part 103 that accommodates the upper chute 101 and the banknote accommodating part 102, and the front surface of the main body part 103. And a mask unit 104 provided with

The upper chute 101 is detachably attached to the main body 103 by an attachment shaft (not shown). Upper chute 101 includes a bill conveyor motor M ₁ which are arranged along the paper passageway 106, and a bill conveyor rollers 108a and 108b. The mask portion 104 can be attached to the main body portion 103 by a fixing tool such as a screw. The main body 103 includes a banknote identification unit 109, a banknote insertion detection sensor unit 110, a shutter unit 111, and a shielding unit 112 disposed in the banknote passage 106 between the banknote insertion port 105 and the banknote insertion detection sensor unit 110. And a biasing means 113 for shielding means such as a spring that biases the shielding means 112 to a position where the banknote passage 106 is shielded, and a stack motor (not shown) that drives the shielding means 112 and the shutter means 111 simultaneously. A driving member 114, conveying rollers 115a and 115b, and a biasing means 116 for shutter means for biasing the shutter means 111 to a position where the banknote passage 106 is not closed are provided. The banknote storage unit 102 drives the stacking unit 119 that presses the banknotes toward the back surface of the banknote storage unit 102, and the stacking unit 119 that accumulates the bundles of banknotes determined to be valid in an aligned state. And a compartment for accommodating a stack motor (not shown). The bill housing part 102 is detachably attached to the main body part 103.

  The banknote passage 106 passes from the banknote insertion port 105 formed on the mask unit 104 to the banknote storage unit 102 along the shielding unit 112, the banknote insertion detection sensor unit 110, the shutter unit 111, and the banknote identification unit 109. The end of the bill passage 106 communicates with the bill accommodation passage area 117 in the bill accommodation portion 102. For convenience of explanation, the bill passage 106 is connected to the first bill passage 106a from the bill insertion slot 105 to the shielding means 112, and the second portion from the shielding means 112 to the position where the tip of the shutter means 111 protrudes into the bill passage 106. The bill passage 106b and the third bill passage 106c from the position where the tip of the shutter means 111 protrudes into the bill passage 106 to the boundary portion between the bill accommodation passage area 117 in the bill accommodation portion 102 are divided.

  The leading end of the bill inserted from the bill insertion slot 105 reaches the shielding means 112 that shields the bill passage 106 between the bill insertion slot 105 and the bill insertion detection sensor means 110. The shielding means 112 is positioned upstream of the banknote insertion detection sensor means 110 and is rotatable in the height direction of the banknote path 106 by a rotating shaft 118 positioned on either the bottom surface or the upper surface of the banknote path. And a connecting portion 112b having one end attached to the bottom of the shielding member 112a and the other end abutting against the side surface of the driving member 114. Since the shielding member 112a needs to shield the banknote passage 106 upstream of the banknote insertion detection sensor means 110 and protect the banknote insertion detection sensor means 110 from disturbance light, at least the banknote path in the direction in which the rotating shaft 118 extends. It is necessary to have a width that matches 106 and to have a length that matches at least the height of the banknote passage 106 in a direction perpendicular to the rotating shaft 118. As long as the above two conditions are satisfied, it may be a generally considered plate-like member or a member of other shapes.

  The connecting portion 112b attached to the shielding member 112a is biased by a biasing means 113 for shielding means such as a compression spring, thereby shielding the banknote passage 106 in a standby state where no banknote is inserted. The shielding member 112a is located at a position where the bill insertion detection sensor means 110 is shielded from the outside. The urging means 113 for the shielding means may be any means that applies an external force in such a direction as to position the shielding member 112a at a position where the banknote passage 106 is shielded. Therefore, instead of urging the connecting portion 112b with a spring, a weight or the like is attached to the portion of the shielding member 112a that shields the banknote passage 106 and the portion that is located in the opposite direction with respect to the rotating shaft 118, and the shielding member 112a is urged by gravity. May be.

  When the leading end of the inserted bill reaches the shielding means 112 located in the bill passage 106 between the bill insertion slot 105 and the bill insertion detection sensor means 110, the bill pushes the shielding member 112a at the leading end. The shielding member 112a is pushed open by the thickness of the banknote and reaches the banknote insertion detection sensor means 110 located downstream of the shielding means 112. When the bill insertion detection sensor means 110 detects the insertion of a bill, a control unit (not shown) drives a stack motor (not shown) to move the driving member 114 downward. One end of the connecting portion 112b of the shielding means 112 is attached to the shielding member 112a, and the other end is in contact with the driving member 114. The driving member 114 has a trapezoidal tip portion 114a protruding in the direction in which the other end portion of the connecting portion 112b is in contact, and a flat portion 114b on the back side of the trapezoidal tip portion 114a. Further, a flat plate portion 114c is provided below the trapezoidal protrusion 114a. When the driving member 114 moves downward, the other end of the connecting portion 112b comes into contact with the trapezoidal tip portion 114a above the flat plate-like portion 114c of the driving member 114 that is initially in contact. As a result, an external force acting in the clockwise direction around the rotation shaft 118 of the shielding member 112a is received. Since the received external force is an external force acting in a direction opposite to the external force applied by the urging means 113 for the shielding means, the shielding member 112a of the shielding means 112 moves from the standby position where no banknote is inserted into the bill passage 106. The shielding member 112a of the shielding means 112 opens the bill passage 106.

  The bill insertion detection sensor means 110 is a transmissive optical sensor, and includes at least one light source, at least one light receiving element, and optical means for guiding light from the light source to the light receiving element. The light source and the light receiving element are arranged in the order of the light source and the light receiving element along the banknote path 106 from the upstream to the downstream in the banknote transport direction. As a light source, not only a normal light bulb but also an element such as a light emitting diode (LED), an organic electroluminescence (EL) element, or a laser diode can be used. When using an LED as a light source, not only a visible light emitting LED but also an ultraviolet emitting LED or an infrared LED may be used. Furthermore, the other end of an optical waveguide such as an optical fiber optically connected at one end to the above-described light emitting element at a remote position may be used as a light source. As the light receiving element, a photodiode, a phototransistor, a photo IC, or the like can be used. The optical means can be formed by using prisms, glass fibers, polymer fibers, fluorinated polyimide for optical waveguides, and other optical waveguide forming members, and are arranged to face each other at a predetermined angle. A pair of mirrors may be used.

  FIG. 2 shows a state immediately after the bill insertion detection sensor means 100 detects the insertion of a bill. The other end of the connecting portion 112b of the shielding means 112 is in contact with the driving member 114, and the driving member 114 is a trapezoid protruding in the direction in which the other end of the connecting portion 112b is in contact. A shape-shaped tip portion 114a, a flat portion 114b on the back side of the trapezoidal tip portion 114a, and a flat plate portion 114c below the trapezoid-shaped projection portion 114a.

  In a standby state in which no banknote is inserted, the other end of the connecting portion 112b of the shielding means 112 abuts on a flat plate-like portion 114c below the trapezoidal tip portion 114a, and the back plate of the shutter means 111 Is in contact with the planar portion 114b on the back side. The biasing means 113 for the shielding means acts to push the connecting portion 112b of the shielding means 112 in the counterclockwise direction, and the shielding means 112 is configured so that the shielding member 112a shields the bill passage 106. It is energized. On the other hand, the shutter means 111 is normally urged by the urging means 116 for the shutter means to a position where the tip thereof does not close the banknote passage 106, but in the standby state, the back plate of the shutter means 111. Is in contact with the planar portion 114b of the driving member 114, and the planar portion 114b presses the tip of the shutter means 111 so as to protrude into the bill passage 106. When the banknote insertion detection sensor means 110 detects the insertion of a banknote, a control unit (not shown) provided in the main body 103 drives a stack motor (not shown) in the banknote storage unit 102 and puts a stack cam on the stack motor. The driving member 114 that is mechanically connected to the first member is moved downward in FIG.

  Therefore, as shown in FIG. 2, when the driving member 114 moves in the direction of the arrow A, the other end of the connecting portion 112b is the flat portion of the driving member 114 that is initially in contact with the driving member 114. By abutting on the trapezoidal tip portion 114a above 114c, an external force acting in the clockwise direction around the rotation shaft 118 of the shielding member 112a is received. Since the received external force is an external force acting in the opposite direction to the external force applied by the urging means 113 for the shielding means, the shielding member 112a of the shielding means 112 moves in the direction of arrow C, and The shielding member 112a is operated so as to open the bill passage 106. When the driving member 114 moves in the direction of the arrow A, the back plate of the shutter means 111 does not come into contact with the planar portion 114b of the driving member 114, and the biasing means 116 for the shutter means inherently applies the biasing force. By moving in the direction of the arrow D, the tip of the shutter means 111 is operated so as to open the bill passage 106. In this state, the first banknote passage 106a from the banknote insertion opening 105 to the shielding means 112, which has been divided, and the second banknote from the shielding means 112 to the position where the tip of the shutter means 111 closes the banknote passage 106. The bill passage 106b and the third bill passage 106c from the position where the tip of the shutter means 111 closes the bill passage 106 to the boundary portion between the bill accommodation passage area 117 in the bill accommodation portion 102 communicate with each other. .

Thereafter, the control unit of the main body portion 103 drives the bill conveyor motor M _1, and drives the conveyor belt bill conveyor motor M ₁ is not shown in the direction of the arrow B, to convey the bills. The banknote transport rollers 108a and 108b and the transport rollers 115a and 115b are driven rollers having no driving force, and rotate by contacting the banknotes to be transported. Thereby, the inserted banknote is transported to the portion where the banknote identifying means 109 is located by the transport belt.

  The bill identifying means 109 collects data for determining the validity of bills. Collection of banknote identification data is performed by using both a magnetic sensor means constituted by a magnetic head and an optical sensor means, and the banknote identification means 109 is used for banknotes inserted based on the collected data. The authenticity of the banknote is determined by performing pattern matching.

  After the data collection by the bill identifying means 109 is completed, the bill is conveyed to a position where the rear end portion of the bill is located downstream of the position where the front end portion of the shutter means 111 closes the bill passage 106. Thereafter, the stack motor of the banknote storage unit 102 moves the driving member 114 in the direction opposite to the direction A. The other end of the connecting portion 112b of the shielding means 112 is not a trapezoidal tip 114a of the driving member 114 that was initially in contact, but a portion 114c on a flat plate located below the trapezoidal tip 114a. Come into contact. As a result, the connecting portion 112b of the shielding means 112 is released from the external force acting in the clockwise direction around the rotation shaft 118 of the shielding member 112a. The external force is an external force acting in a direction opposite to the external force applied by the urging means 113 for the shielding means. Therefore, when the external force is released from the external force, the external force for the shielding means in the direction opposite to the acting external force is applied. Due to the urging force provided by the urging means 113, the shielding member 112a of the shielding means 112 moves in a direction opposite to the direction of the arrow C, and the shielding member 112a of the shielding means 112 shields the bill passage 106 again. When the driving member 114 moves in the direction opposite to the direction A, the back plate of the shutter means 111 comes into contact with the planar portion 114b of the driving member 114 again. As a result, the back plate of the shutter means 111 is pressed by the flat portion 114b, and the shutter means 111 moves in the direction opposite to the direction D against the urging force provided by the urging means 116 for the shutter means. Then, the front end portion of the shutter means 111 is operated so as to close the bill passage 106. Thus, again, the first bill passage 106a from the bill insertion slot 105 to the shielding means 112, the second bill passage 106b from the shielding means 112 to the position where the tip of the shutter means 111 closes the bill passage 106, The third banknote path 106c from the position where the tip of the shutter means 111 closes the banknote path 106 to the boundary portion with the banknote storage path area 117 in the banknote storage section 102 is separated.

In this case, the stacking means 119 that presses the banknote into the banknote storage unit 102 is at the standby position, that is, on the front side of the banknote storage unit 102 with respect to the banknote storage passage area 117, and faces the back of the banknote storage unit 102. Therefore, the third portion 106c of the bill passage 106 and the bill accommodation passage area 117 are in communication with each other. The banknote is temporarily held in a space (escrow banknote position) where the third portion 106c of the banknote path 106 communicates with the banknote storage path area 117. This escrow bill position is caused by the shielding means 112 and the shutter means 111 opening the bill passage 106 once and then closing it, whereas the stacking means 119 does not move at all from the standby position. is there. Above it is intended to be achieved by the inherent shape of the mechanical link, and the driving member 114 between the stack cam and the driving member 114 that is mechanically coupled to the stack motor M ₂ to be described later is there.

While the banknote is temporarily held in the escrow banknote position, the banknote identification means 109 determines the authenticity of the banknote by performing pattern matching on the banknote inserted based on the collected data. If the bill the bill identification means 109 is inserted is determined not to be valid, the bill identification means 109 does not output a genuine bill signal, the control unit controls the stack motor M ₂ of the bill housing part 102 Then, the driving means 114 is moved again in the direction of arrow A, the shielding member 112a of the shielding means 112 is moved in the direction C to open the bill passage 106, and the shutter means 111 is moved in the direction D. The bill passage 106 is opened, and the first bill passage 106a, the second bill passage 106b, and the third bill passage 106c of the bill passage 106 are communicated. Thereafter, the control unit is to the motor M ₁ control bill conveyor, the conveyor belt is reversely rotated, the inserted bill through the bill passage 106 conveys in the opposite direction to the B, and the bill insertion slot 105 return. When the banknote identification unit 109 determines that the inserted banknote is valid, the banknote identification unit 109 outputs a genuine note signal, and the control unit instructs the banknote storage unit 102 to convey the banknote. To do. A conveyance position detection sensor (not shown) is provided along the bill passage 106, and the conveyance position detection sensor detects the conveyance position of the bill. If the banknote is detected in the order of the banknote position detection sensor and the banknote insertion detection sensor means 110 before the shutter means 111 blocks the banknote passage 106, it is determined that the banknote has been illegally extracted, and the banknote The identification means 109 does not output a bill note signal.

  The bill storage unit 102 includes a stack unit 119, a stack arm having a pantograph structure (not shown) connected to the stack unit 119, a section for storing a stack motor that drives the stack arm of the pantograph structure, and a bill storage unit. It consists of compartments. A section for storing banknotes is partitioned by a guide 120, and the banknotes that have passed through the banknote identifying means 109 are guided into a banknote storage passage area 117 located downstream of the terminal end of the third banknote path 106c of the banknote path 106. Is done. The stacking means 119 presses the banknote guided into the banknote storage passage area 117 from the inside of the banknote storage path area 117 toward the rear part from the guide 120 and stores it in a section for storing banknotes.

  FIG. 3 is a view as seen from the oblique rear side of the banknote recognition apparatus 100, with the section for storing banknotes in the upper chute 101 and the banknote storage section 102 removed from the banknote identification apparatus 100, and further the stack means 119 removed. is there. The driving means 201 includes a stack motor 301 and a stack cam 302 that rotates by engaging with a gear of the stack motor 301. The stack cam 302 includes a projecting portion 302a that is eccentric from the rotation axis by a distance a. The driving means 114 includes a planar portion 114b that presses the back plate of the shutter means 111 as described in relation to FIGS. 1 and 2, and is further located below the planar portion 114b. A slightly longer planar portion 114d that is slightly depressed as compared to the planar portion 114b, and a slope portion 114e that forms a slope so as to protrude from the planar portion 114d toward the back surface of the bill validator 100. And a slit 114f is provided below the slope portion 114e. The protruding portion 302a of the stack cam 302 is engaged with (received in) the slit 114f of the driving member 114, and the mechanical link between the driving member 114 and the stack cam 302 is formed by the protruding portion 302a and the slit 114f. Is achieved.

  As the stack cam 302 rotates, the driving member 114 moves up and down, so that the shutter member 111 and the shielding means 112 close the bill passage 106 or open the bill passage 106 so that the shutter member 111 and the shielding means 112 open the bill passage 106. The means 112 is operated. In front of the driving member 114, the driving member 114 is arranged slightly spaced from the slightly longer planar portion 114d of the driving member 114 in the direction of the back surface of the banknote recognition apparatus 100. The stack roller 303 that moves up and down the inclined surface portion 114e of the drive member 114, and supports the stack roller 303 in a rotatable manner, and as the drive member 114 moves up and down, in the front-rear direction, that is, the front surface of the bill recognition device 100 and A stack shaft 304 that moves in a direction perpendicular to the back surface is disposed. Further, the stack shaft 304 is fitted and inserted by the stack guide 306 and coupled to the back surface of the stack means 119, thereby moving the stack means 119 in the front-rear direction, that is, in the direction perpendicular to the front surface and the back surface of the banknote storage portion 102. Stack arms 305 are disposed on both sides of the drive member 114.

  4 to 7 show the relationship between the rotational movement of the stack cam 302 and the vertical movement of the driving member 114 in each state, and the shielding means 112 and the shutter means associated with the vertical movement of the driving member 114 in each state. FIG. 11 is a diagram for explaining the operation of 111 and stack means 119.

FIG. 4A is a diagram showing a state in which no banknote is inserted in the banknote recognition apparatus 100, that is, a state where the banknote identification apparatus is in a standby state. Considering a reference line Y extending downward along the direction of movement of the driving member 114 from the rotation axis 302b of the stack cam 302, as shown in FIG.4 (b), the protruding portion 302a of the stack cam 302 is It is at a position rotated from the reference line Y by an angle α _{1 in the} counterclockwise direction. Here, the highest position of the protruding portion 302a of the stack cam 302, that is, the position of the protruding portion 302a when the distance between the protruding portion 302a and the rotation shaft 302b of the stack cam 302 is a, and the protruding portion 302a in each state. In the state shown in FIG. 4 (b), h = a (1 + cosα ₁ ) where h is the height difference from the position of h. Therefore, in this state, the driving member 114 is positioned 2a−h, that is, a (1−cosα ₁ ) above the lowest point. In this state, the other end of the connecting portion 112b of the shielding means 112 is in contact with a flat plate-like portion 114c below the trapezoidal tip portion 114a, and the back plate of the shutter means 111 is a flat plate on the back side. It is in contact with the portion 114b. The biasing means 113 for the shielding means acts to push the connecting portion 112b of the shielding means 112 in the counterclockwise direction, and the shielding means 112 is configured so that the shielding member 112a shields the bill passage 106. It is energized. In the standby state, the back plate of the shutter unit 111 is in contact with the planar portion 114b of the driving member 114 so that the leading end portion of the shutter unit 111 protrudes into the bill passage 106 by the planar portion 114b. Is pressed. The stacking means 119 is located at a position before the banknote is pressed toward the back of the banknote recognition apparatus 100, that is, at a standby position. Therefore, in this state, the third banknote passage 106c and the banknote storage passage area from the position where the tip of the shutter means 111 closes the banknote path 106 to the boundary portion with the banknote storage path area 117 in the banknote storage section 102. 117 communicates with each other and forms an escrow banknote area.

When the leading end of the inserted banknote reaches the shielding means 112 positioned in the banknote passage 106 between the banknote insertion slot and the banknote insertion detection sensor means 110, the banknote presses the shielding member 112a at the leading end of the banknote. The shielding member 112a is pushed open by the thickness of the sheet and reaches the banknote insertion detection sensor means 110 located downstream of the shielding means 112. When the bill insertion detecting sensor unit 110 detects the insertion of the bill, the control unit (not shown) controls the stack motor M ₂ is driven, the stack motor M ₂ is an angle alpha ₁ of the stack cam 302 in a clockwise direction Rotate. At this time, the protruding portion 302a of the stack cam 302 is at the lowest point, that is, the protruding portion 302a is located at a position where h = 2a. Accordingly, the driving means 114 moves downward by a (1−cosα ₁ ). Stack motor M ₂ is, after rotating the stack cam 302 in a clockwise direction by an angle alpha _1, it is controlled so as temporarily stopped. Rotation angle of stack cam uses a pulse encoder may be detected in a known manner, by feeding back the information to the control unit, the control unit controls the stack motor M _2.

4 (a) and (b) to the bill validator 100 of the stack cam 302 while rotating in the clockwise direction by an angle alpha ₁ in the state shown is shown in Figure 5 (a). In this state, when the driving means 114 moves downward by a (1−cosα ₁ ), the other end of the connecting portion 112b becomes trapezoidal tip 114a above the flat plate portion 114c. By abutting, an external force acting in a clockwise direction around the rotation shaft 118 of the shielding member 112a is received. Since the external force is an external force acting in a direction opposite to the external force applied by the urging means 113 for the shielding means, the shielding member 112a of the shielding means 112 resists the urging force provided by the urging means 113 for the shielding means. Then, the bill passage 106 is operated to be opened. On the other hand, the back plate of the shutter unit 111 does not come into contact with the planar portion 114b of the driving member 114, and due to the urging force originally applied by the urging unit 116 for the shutter unit, the tip of the shutter unit 111 has a bill passage. Operates to release 106.

  The stack roller 303 is arranged slightly spaced from the slightly longer planar portion 114d of the driving member 114 in the direction of the back surface of the bill validating device 100, and the stack shaft 304 rotatably supports the stack roller 303, As the driving member 114 moves up and down, it is arranged to move in the front-rear direction, that is, in a direction perpendicular to the front surface and the back surface of the banknote recognition apparatus 100. As shown in FIG. 5A, in this state, the stack roller 303 does not reach the inclined surface portion 114e of the drive member 114, and the stack roller 303 does not contact the drive member 114. Therefore, the stack shaft 304 does not move toward the back surface in a direction perpendicular to the back surface of the banknote recognition apparatus 100. The stack arm 305 of the pantograph structure is inserted in the stack shaft 304 by the stack guide 306 and coupled to the back surface of the stack device 119, thereby moving the stack device 119 in the front-rear direction, that is, in the direction perpendicular to the front surface and the back surface of the bill storage unit 102. Arranged to exercise. Therefore, even when this state is reached, the stack means does not move from the standby position. Accordingly, in this state, the first banknote passage 106a from the banknote insertion opening 105 to the shielding means 112, which has been divided, and the position from the shielding means 112 to the position where the tip of the shutter means 111 closes the banknote path 106 are separated. The second banknote path 106b communicates with the third banknote path 106c from the position where the tip of the shutter means 111 closes the banknote path 106 to the boundary portion with the banknote storage path area 117 in the banknote storage section 102. . Further, the third banknote passage 106c and the banknote storage passage area 117 from the position where the front end portion of the shutter means 111 closes the banknote path 106 to the boundary portion with the banknote storage passage area 117 in the banknote storage section 102 communicate with each other. The escrow banknote area is formed.

When the first bill passage 106a and the second bill passage 106b and the third bill passage 106c communicates to drive the transport driving belt the conveying drive motor M ₁ is not shown, the bill of the bill housing part 102 conveyed to the bill accommodating passage zone 117, then, the conveyance drive motor M ₁ is stopped by the control of the control unit. After conveying drive motor M ₁ is to transport the bills to the bill accommodating passage region 117, the control unit controls the stack motor M ₂ is driven, the stack motor M ₂ is a stack cam 302 in a clockwise direction angle alpha ₁ is rotated. In this state, the protruding portion 302a of the stack cam 302 moves upward by a (1−cosα ₁ ) from the lowest point, that is, a position where h = 2a, and h = a (1 + cosα ₁ ). It is in such a position. Along with this, the driving member 114 is also moved upward by a (1−cos α ₁ ). At this time, the other end of the connecting portion 112b of the shielding means 112 abuts on a flat plate-like portion 114c below the trapezoidal tip portion 114a, and the biasing means 113 for the shielding means is connected to the shielding means 112. Since the portion 112b acts to push the portion 112b in the counterclockwise direction, the shielding means 112 is biased so that the shielding member 112a shields the bill passage 106. On the other hand, since the back plate of the shutter means 111 is in contact with the planar portion 114b on the back side, the back plate of the shutter means 111 is in contact with the planar portion 114b of the driving member 114, and the planar shape The tip 114b of the shutter means 111 is pressed so as to close the bill passage 106.

  Furthermore, since the stack roller 303 is arranged slightly spaced from the planar portion 114d of the driving member 114 in the direction of the back surface of the banknote recognition apparatus 100, as shown in FIG. 6 (a). The stack roller 303 is approaching the inclined surface portion 114e of the driving member 114, but is not pressed by the inclined surface portion 114e of the driving member 114. It does not move toward its back in a vertical direction. The pantograph-structured stack arm 305 also does not move the stacking means 119 toward the back surface in a direction perpendicular to the back surface of the bill validating device 100. Therefore, even when this state is reached, the stack means does not move from the standby position. Accordingly, the first banknote path 106a, the second banknote path 106b, and the third banknote path 106c are separated from each other, but the third banknote path 106c and the banknote storage path area 117 communicate with each other. The escrow banknote area is formed. In this state, reverse feeding of banknotes is prevented, so it is possible to eliminate attempts such as unauthorized withdrawal of banknotes. In this state, that is, while banknotes are temporarily held in the escrow banknote position. The authenticity of the inserted banknote is determined based on the collected data.

As described above, when the angle θ between the line connecting the protruding portion 302a of the stack cam 302 and the rotation shaft 302b of the stack cam 302 and the reference line Y is within the angle range −α ₁ ≦ θ ≦ α ₁ , that is, When the driving member 114 is between the lowest position and a position moved by a (1-cosα ₁ ) from the lowest position, the shutter means 111 and the shielding means 112 open and close the bill passage 106. Although the operation is performed, the stack unit 119 does not move from the standby position. Therefore, this area becomes the non-operating area of the stack means 119.

When the bill is judged as authentic, the control unit controls the stack motor M ₂ is driven, the stack motor M ₂ is a stack cam 302 in a clockwise direction by an angle [pi-alpha ₁ rotation Let In this state, the protruding portion 302a of the stack cam 302 moves upward by a (1 + cosα ₁ ) from the uppermost point, that is, a position where h = 2a, and is in a position where h = 0. Along with this, the driving member 114 also moves up by a (1 + cosα ₁ ). At this time, as shown in FIG. 7A, the shielding means 112 and the shutter means 111 maintain a state in which the banknote passage 106 is closed. On the other hand, the stack roller 303 climbs up the sloped portion 114e of the driving member 114, and ascends the sloped portion 114e while being pressed by the sloped portion 114e of the driving member 114. Move towards the back in any direction. The stack arm 305 having a pantograph structure also moves the stack means 119 toward the back surface in a direction perpendicular to the back surface of the bill validating device 100. Therefore, when this state is reached, the stack means moves from the standby position to the bill pressing position. Therefore, as described above, when the angle θ between the line connecting the protruding portion 302a of the stack cam 302 and the rotation shaft 302b of the stack cam 302 and the reference line Y is within the angle range α ₁ ≦ θ ≦ 2π−α ₁ That is, when the driving member 114 is between the position moved from the lowest position by a (1-cosα ₁ ) and the uppermost position, the shutter means 111 and the shielding means 112 open and close the banknote passage 106. Without performing this operation, the stacking means 119 moves from the standby position to the bill pressing position. Therefore, this area is a non-operation area of the shutter unit 111 and the shielding unit 112.

After accommodated in the bill accommodating unit 102 presses the bill, the control unit controls the stack motor M ₂ is driven, the stack cam 302 and the driving means 114, FIGS. 4 (a) and 4 (b) Return to the standby state shown in. As described above, when the driving member 114 is between the lowest position and a position moved a (1-cosα ₁ ) from the lowest position, the shutter unit 111 and the shielding unit 112 are bills. Although the opening / closing operation of the passage 106 is performed, the stack unit 119 does not move from the standby position, and this region becomes the non-operation region of the stack unit 119. On the other hand, when the driving member 114 is between the position moved up by a (1-cos α ₁ ) from the lowest position and the uppermost position moved by 2 a from the lowest position, the shutter means 111 and the shielding means 112 does not perform the opening / closing operation of the banknote passage 106, and the stack unit 119 moves from the standby position to the banknote pressing position, so this area becomes an inoperative area of the shutter unit 111 and the shielding unit 112. Here, a is the distance between the rotation center shaft 302b of the stack cam 302 and the protruding portion 302a. It is within the scope of the creation of those skilled in the art to optimize the above a and α ₁ so as to take optimum values.

  To summarize the above, since the shielding means 112 and the shutter means 111 or the stacking means 119 do not operate due to the mechanical link between the stack cam 302 and the driving member 114, the shielding means 112 and the shutter means are provided. 111 allows the three portions of the bill passage 106 to communicate with each other, and the stack means 119 to ensure that the terminal portion of the third bill passage 106c of the bill passage 106 is not closed by the stack means. The banknote accommodating passage area 117 communicating with the third portion 106c of the banknote path 106 can be used as an area for temporarily storing banknotes. This significantly contributes to the miniaturization of the banknote recognition apparatus 100. Further, as described above, according to the banknote identification device of the present invention, the influence of disturbance light is eliminated by the shielding means provided in the banknote passage between the banknote insertion slot and the banknote insertion detection sensor means. Therefore, it is possible to mainly prevent malfunction of the banknote insertion detection sensor means.

  The above description relates to one embodiment of the present invention, and the gist of the present invention should not be construed as being limited thereto. Various modifications can be made by those skilled in the art in the technical field of the present invention.
