Description

[Technical field]

[0001] The present invention relates to a media processing device. [Background technology]

[0002] In a banknote processing device that handles banknotes, which are a type of medium, for example, when depositing banknotes, the banknotes inserted into a banknote insertion slot are transported along a transport path, and a discrimination section provided on the transport path identifies the denomination of the banknotes, and the banknotes are stored in a banknote storage vault by denomination.

[0003] In such a banknote processing device, a so-called jam may occur in which banknotes get stuck in the transport path, for example, a jam may occur in the discriminator. For this reason, a conventional discriminator is composed of a lower part located on the lower side with the transport path in the discriminator, which is a space through which banknotes pass, sandwiched therebetween, and an upper part located on the upper side with the transport path in the discriminator sandwiched therebetween and capable of opening and closing with respect to the lower part, and by opening the upper part with respect to the lower part, it is possible to remove banknotes (called jammed banknotes) that are stuck in the discriminator (i.e., the transport path in the discriminator) (see, for example, Patent Document 1). [Prior art documents] [Patent documents]

[0004] [Patent Document 1] JP 2005-4649 A Summary of the Invention [Problem to be solved by the invention]

[0005] Incidentally, the discrimination unit has a sensor that is used to determine the denomination of the banknotes passing through the discrimination unit. Examples of sensors that the discrimination unit has include an optical sensor having a light-emitting unit and a light-receiving unit, and a magnetic sensor having a transmitting unit and a receiving unit. In these sensors, for example, a first sensor component such as a light-emitting unit and a transmitting unit is provided on the upper section side, and a second sensor component such as a light-receiving unit and a receiving unit is provided on the lower section side.

[0006] However, as with conventional banknote processing devices, when the upper section is opened and closed relative to the lower section to remove jammed banknotes in the validation section, the relative positions of the first sensor component provided on the upper section side and the second sensor component provided on the lower section side are shifted, resulting in a problem of a decrease in the sensor performance (i.e., validation accuracy) of the validation section.

[0007] The present invention has been made in consideration of the above points, and aims to propose a media processing device that prevents the relative positions of the first sensor component and the second sensor component from shifting, and is capable of removing jammed media in the discrimination section. [Means for solving the problem]

[0008] In order to solve this problem, the media processing device of the present invention comprises a media transport path, an identification unit provided on the transport path for identifying the media transported along the transport path, and a transport guide provided along the transport path for guiding the media, the transport guide comprising a first transport guide formed on one side of the transport path and a second transport guide formed on the other side of the transport path, the identification unit comprising a first sensor component and a second sensor component, and a holding member having a media passing hole through which the media passes, the holding member holding the first sensor component on one side of the media passing hole and the second sensor component on the other side, and one of the first transport guide and the second transport guide is provided with a fixing unit for fixing the holding member so that the media passing hole of the holding member is connected to the transport path, the first sensor component is located on the first transport guide side, and the second sensor component is located on the second transport guide side.

[0009] In this way, since the first sensor part and the second sensor part of the discrimination unit are integrated by the holding member, even if the first guide part is opened and closed relative to the second guide part to remove jammed media inside the discrimination unit, it is possible to prevent the relative positions of the first sensor part and the second sensor part from being shifted. Effect of the Invention

[0010] According to the present invention, it is possible to realize a media processing device that can prevent the relative positions of the first sensor component and the second sensor component from shifting and remove jammed media in the discrimination unit. [Brief description of the drawings]

[0012] Hereinafter, modes for carrying out the invention (hereinafter referred to as embodiments) will be described with reference to the drawings.

[0013] [1. Configuration of the banknote processing device] FIG. 1 shows a configuration example of a banknote processing device 1. The banknote processing device 1 is, for example, a device mounted on a self-service settlement machine used in a retail store or a deposit / withdrawal machine in a back office. The banknote processing device 1 has a transport path R that is a path for banknotes and extends along the transport direction of the banknotes, and a discrimination unit 10 that is provided in the middle of the transport path R and discriminates the denomination of the banknotes. In FIG. 1, as an example, a part of the transport path R extends in the horizontal direction (left and right direction in FIG. 1), and the discrimination unit 10 is provided in this part. In addition, with respect to the transport path R, the direction that crosses the transport path R (depth direction in FIG. 1) is defined as the width direction, and the direction perpendicular to both the transport direction and the width direction of the transport path R is defined as the height direction of the transport path R. Therefore, the vertical direction in FIG. 1 is the height direction for the part of the transport path R that extends horizontally. In the banknote processing device 1 shown in FIG. 1, the parts other than the transport path R and the discrimination unit 10 are omitted because they are the same as, for example, existing configurations. In addition, in the banknote handling device 1, the banknote is transported such that the longitudinal direction of the banknote is the width direction of the transport path R, and the lateral direction of the banknote is the transport direction of the transport path R.

[0014] This banknote processing device 1 has both or either of a deposit function and a withdrawal function. Here, a case where the banknote processing device 1 has both the deposit function and the withdrawal function will be described. That is, when depositing banknotes, the banknote processing device 1 sends out the banknotes inserted by the user into a banknote inlet / outlet (not shown) one by one in order to a transport path R, and while transporting the banknotes along the transport path R, a discrimination unit 10 provided in the middle of the transport path R discriminates the denomination of the banknote. Then, the banknote processing device 1 transports the banknotes to a banknote storage vault corresponding to the discriminated denomination among banknote storage vaults (not shown) provided for each denomination, and stores the banknotes in the banknote storage vault. When depositing banknotes, the banknote processing device 1 returns the banknotes that are discriminated as rejected banknotes that cannot be deposited by the discrimination unit 10 to the banknote inlet / outlet and returns them to the user without storing them in the banknote storage vault.

[0015] On the other hand, when dispensing banknotes, the banknote processing device 1 feeds out banknotes of an amount specified by a user via, for example, an operation display panel (not shown) one by one from each banknote storage vault provided for each denomination onto the transport path R, and while transporting the banknotes along the transport path R, the validator 10 discriminates the denomination of the banknotes. The banknote processing device 1 then transports the banknotes to a banknote inlet / outlet for receipt by the user. When dispensing banknotes, the banknote processing device 1 stores banknotes that are discriminated by the validator 10 as rejected banknotes that are not suitable for dispensing in a rejected vault (not shown) without transporting them to the banknote inlet / outlet. The configuration of the banknote processing device 1 is as described above.

[0016] [2. Composition of the Identification Department] Next, the configuration of the discrimination unit 10 will be described with reference to Fig. 2 to Fig. 4. Fig. 2 is an external perspective view of the discrimination unit 10, Fig. 3 is a cross-sectional view of the discrimination unit 10 cut at the center in the longitudinal direction, and Fig. 4 is an exploded perspective view of the discrimination unit 10. In Fig. 2 to Fig. 4, directions related to the discrimination unit 10 are defined as X-direction, Y-direction, and Z-direction.

[0017] 2, the discrimination unit 10 has an elongated rod shape as a whole, with a length in the longitudinal direction (Y direction) longer than the width of the transport path R (FIG. 1), and is provided midway along the transport path R so as to cross the transport path R. The discrimination unit 10 has an image sensor 20 and a cartridge 21 that holds the image sensor 20.

[0018] The image sensor 20 is, for example, a transmissive optical sensor, and as shown in FIG. 4, is composed of two components: a sensor component 20A on the light-emitting side (referred to as light-emitting side sensor component 20A) and a sensor component 20B on the light-receiving side (referred to as light-receiving side sensor component 20B).

[0019] The light-emitting unit side sensor part 20A is a part that includes a light-emitting element (not shown) and emits light by the light-emitting element. The light-emitting unit side sensor part 20A has a long and thin rectangular prism shape, and one side 30A of four side surfaces extending in the longitudinal direction (Y direction) is a light-emitting surface, and a connector 32A for power supply and signal transmission and reception is provided on the other side 31A opposite to the one side 30A. The length of the light-emitting unit side sensor part 20A in the longitudinal direction (Y direction) is slightly longer than the width of the transport path R, for example. The distance (length in the Z direction) from one side 30A to the other side 31A of the light-emitting unit side sensor part 20A is defined as the thickness (also the height) of the light-emitting unit side sensor part 20A. Here, the longitudinal direction (Y direction) and the short side direction (X direction) of the one side 30A of the light-emitting unit side sensor part 20A are defined as the longitudinal direction and the short side direction of the light-emitting unit side sensor part 20A.

[0020] On the other hand, the light-receiving unit side sensor part 20B is a part that includes a light-receiving element (not shown) and receives light by the light-receiving element. The light-receiving unit side sensor part 20B has substantially the same shape and size as the light-emitting unit side sensor part 20A, and one side 30B of the four side surfaces extending in the longitudinal direction (Y direction) is a light-receiving surface, and a connector 32B (see FIG. 3) for power supply and signal transmission and reception is provided on the other side 31B opposite to the one side 30B. The length of the light-receiving unit side sensor part 20B in the longitudinal direction (Y direction) is also slightly longer than the width of the conveying path R, for example, like the light-emitting unit side sensor part 20A. Note that, for the light-receiving unit side sensor part 20B, the distance (length in the Z direction) from one side 30B to the other side 31B is defined as the thickness (also the height) of the light-receiving unit side sensor part 20B. As for the light-receiving unit side sensor component 20B, the longitudinal direction (Y direction) and the lateral direction (X direction) of one side surface 30B are defined as the longitudinal direction and the lateral direction of the light-receiving unit side sensor component 20B.

[0021] The cartridge 21 is generally rod-shaped and slightly larger than the light-emitting unit side sensor component 20A and the light-receiving unit side sensor component 20B. In this case, the longitudinal direction (Y direction) and the short-side direction (X direction) of a first side surface 41, which is one of the four side surfaces extending in the longitudinal direction (Y direction) of the cartridge 21, are defined as the longitudinal direction and the short-side direction of the cartridge 21 in accordance with the light-emitting unit side sensor component 20A and the light-receiving unit side sensor component 20B, and the distance (length in the Z direction) between the first side surface 41 and the second side surface 42, which is the other side surface opposite to the first side surface 41, is defined as the thickness (also the height) of the cartridge 21. The thickness of the cartridge 21 is also the length in the short-side direction (Z direction) of each of a third side surface 43 and a fourth side surface 44 connecting the first side surface 41 and the second side surface 42, which are the four side surfaces extending in the longitudinal direction (Y direction) of the cartridge 21.

[0022] That is, the length of the cartridge 21 in the longitudinal direction (Y direction) and the length of the short side (X direction) are slightly longer than the lengths of the light emitter side sensor component 20A and the light receiver side sensor component 20B in the longitudinal direction and the short side, respectively, and the thickness (length in the Z direction) is slightly more than twice the thickness of the light emitter side sensor component 20A and the light receiver side sensor component 20B. In addition, the thickness of the cartridge 21 is sufficiently greater than the height of the transport path R.

[0023] The cartridge 21 is provided with a through hole H1 penetrating in the thickness direction (Z direction) of the cartridge 21 from the first side surface 41 to the second side surface 42. The through hole H1 is a hole for fitting the light emitter side sensor component 20A and the light receiver side sensor component 20B, and is hereinafter referred to as a sensor fitting hole H1. The sensor fitting hole H1 extends along the longitudinal direction (Y direction) of the first side surface 41 and the second side surface 42. The length of the sensor fitting hole H1 in the longitudinal direction (Y direction) is approximately the same as the longitudinal length of the light emitter side sensor component 20A and the light receiver side sensor component 20B, and the length of the sensor fitting hole H1 in the lateral direction (X direction) is also approximately the same as the lateral length of the light emitter side sensor component 20A and the light receiver side sensor component 20B.

[0024] The cartridge 21 is also provided with a through hole H2 that penetrates the cartridge 21 in the short-side direction (X direction) from the third side surface 43 to the fourth side surface 44. This through hole H2 is provided in the center part of each of the third side surface 43 and the fourth side surface 44 in the short-side direction (Z direction) (i.e., the center part in the thickness direction of the cartridge 21). The through hole H2 is a hole that connects to the transport path R shown in FIG. 1 (i.e., a hole through which a banknote passes), and will be referred to as the banknote passing hole H2 hereinafter. The length of this banknote passing hole H2 in the longitudinal direction (Y direction) is approximately the same as the width of the transport path R, and the height (length in the Z direction) is approximately the same as the height of the transport path R.

[0025] The sensor insertion hole H1 and the bill passing hole H2 are connected to each other inside the cartridge 21 so as to intersect with each other.

[0026] Furthermore, the cartridge 21 is provided with a protrusion 50 and a protrusion 51, which protrude from the third side surface 43 in the short direction (X direction) of the cartridge 21, on the first side surface 41 side at one end of the third side surface 43 in the longitudinal direction (Y direction) and on the first side surface 41 side at the other end. The protrusion 50 is a plate-like member that is sufficiently thinner than the cartridge 21, and its thickness (length in the Z direction) is thinner than the distance between the banknote passing hole H2 and the first side surface 41. The protrusion 50 is provided so that one surface on the first side surface 41 side is flush with the first side surface 41, and further has a cylindrical through hole H3 penetrating in the thickness direction (Z direction).

[0027] The protrusion portion 51 is plate-shaped and of the same size as the protrusion portion 50, and like the protrusion portion 50, one surface on the first side surface 41 side is flush with the first side surface 41, and further has a rectangular prism-shaped through hole H4 that penetrates in the thickness direction (Z direction).

[0028] Furthermore, the cartridge 21 is provided with a plurality of protrusions 52 protruding in the short direction (X direction) of the cartridge 21 at regular intervals in the longitudinal direction (Y direction) of the cartridge 21 between one end and the other end of the third side surface 43. The protrusions 52 are rectangular prisms whose length in the direction parallel to the longitudinal direction of the cartridge 21 (length in the Y direction) is sufficiently shorter than that of the cartridge 21, and are provided facing the first side surface 41 side and the second side surface 42 side with the bill passing hole H2 therebetween. Here, the protrusion 52 provided on the first side surface 41 side with the bill passing hole H2 therebetween is referred to as protrusion 52A, and the protrusion 52 provided on the second side surface 42 side is referred to as protrusion 52B.

[0029] That is, on the third side surface 43, a plurality of convex portions 52A are provided at regular intervals in the longitudinal direction (Y direction) on the first side surface 41 side with the bill passing hole H2 in between, and a plurality of convex portions 52B are provided on the second side surface 42 side with the bill passing hole H2 in between so as to face the convex portions 52A. In other words, on the third side surface 43, an uneven portion 53A in which concave portions (parts between convex portions 52A and 52A) and convex portions 52A are alternately arranged in the longitudinal direction is provided on the first side surface 41 side with the bill passing hole H2 in between, and an uneven portion 53B in which concave portions (parts between convex portions 52B and 52B) and convex portions 52B are alternately arranged in the longitudinal direction is provided on the second side surface 42 side.

[0030] As shown in FIG. 3, the protrusion 52A on the first side surface 41 side is a rectangular prism extending from the first side surface 41 to the banknote passing hole H2, and the corner 60 on the banknote passing hole H2 side of the tip end farthest from the third side surface 43 (i.e., the tip end in the X direction) has a chamfered tapered shape.

[0031] On the other hand, the protrusion 52B on the second side surface 42 side is a quadrangular prism extending from the second side surface 42 to the bill passing hole H2, and a corner 61 on the bill passing hole H2 side of the tip end farthest from the third side surface 43 (i.e., the tip end in the X direction) has a chamfered tapered shape. In this way, the protrusions 52A and 52B have symmetrical shapes with respect to the bill passing hole H2.

[0032] In addition, since the corners 60, 61 on the banknote passing hole H2 side of the tip of each of the convex portions 52A and 52B are tapered as if they have been chamfered, the distance between the convex portions 52A and 52B widens toward the tip side.

[0033] 4, the cartridge 21 is provided on the fourth side surface 44 with protrusions 54 and 55 at one end and the other end in the longitudinal direction (Y direction) of the cartridge 21, respectively. The protrusions 54 and 55 are plate-shaped and have the same size as the protrusion 50 on the third side surface 43 side, and are provided such that one surface on the first side surface 41 side is flush with the first side surface 41, similar to the protrusion 50. The protrusion 54 has a cylindrical through hole H5 penetrating in the thickness direction (Z direction), and the protrusion 55 has a cylindrical through hole H6 penetrating in the thickness direction (Z direction).

[0034] Furthermore, on the fourth side surface 44 side of the cartridge 21, similar to the third side surface 43 side, between one end and the other end of the fourth side surface 44, multiple protrusions 56 protruding in the short direction (-X direction) of the cartridge 21 are provided at regular intervals in the longitudinal direction (Y direction) of the cartridge 21.

[0035] Like the protrusion 52 on the third side surface 43 side, this protrusion 56 has a rectangular prism shape whose length in a direction parallel to the longitudinal direction of the cartridge 21 (length in the Y direction) is sufficiently shorter than that of the cartridge 21, and is provided facing the first side surface 41 side and the second side surface 42 side with the bill passing hole H2 therebetween, as shown in Fig. 3. Here, the protrusion 56 provided on the first side surface 41 side with the bill passing hole H2 therebetween is referred to as protrusion 56A, and the protrusion 56 provided on the second side surface 42 side is referred to as protrusion 56B.

[0036] That is, on the fourth side surface 44, similar to the third side surface 43 side, a plurality of convex portions 56A are provided at regular intervals in the longitudinal direction (Y direction) on the first side surface 41 side with the bill passing hole H2 therebetween, and a plurality of convex portions 56B are provided on the second side surface 42 side with the bill passing hole H2 therebetween so as to face the convex portions 56A. In other words, on the fourth side surface 44, similar to the third side surface 43 side, an uneven portion 57A in which concave portions (parts between convex portions 56A and convex portions 56A) and convex portions 56A are alternately arranged in the longitudinal direction is provided on the first side surface 41 side with the bill passing hole H2 therebetween, and an uneven portion 57B in which concave portions (parts between convex portions 56B and convex portions 56B) and convex portions 56B are alternately arranged in the longitudinal direction is provided on the second side surface 42 side.

[0037] As shown in FIG. 3, the protrusion 56A on the first side surface 41 side is a rectangular prism extending from the first side surface 41 to the banknote passing hole H2, and the corner 62 on the banknote passing hole H2 side of the tip end farthest from the third side surface 43 (i.e., the tip end in the -X direction) has a chamfered tapered shape.

[0038] On the other hand, the protrusion 56B on the second side surface 42 side is a quadrangular prism extending from the second side surface 42 to the bill passing hole H2, and a corner 63 on the bill passing hole H2 side of the tip end farthest from the third side surface 43 (i.e., the tip end in the X direction) is chamfered to have a tapered shape. In this way, the protrusions 56A and 56B are symmetrical with respect to the bill passing hole H2.

[0039] In addition, the corners 62, 63 of the tip of each of the convex portions 56A and 56B on the side of the banknote passing hole H2 are chamfered to have a tapered shape, so that the distance between the convex portions 56A and 56B widens toward their tips.

[0040] The cartridge 21 has such a configuration, and the light-emitting unit side sensor component 20A and the light-receiving unit side sensor component 20B are fitted into the sensor fitting hole H1 and fixed to the cartridge 21 to hold them. Specifically, for example, as shown in Fig. 4, the light-emitting unit side sensor component 20A is fitted into the sensor fitting hole H1 from the first side surface 41 side of the cartridge 21, and the light-receiving unit side sensor component 20B is fitted into the sensor fitting hole H1 from the second side surface 42 side of the cartridge 21. At this time, the light-emitting unit side sensor component 20A and the light-receiving unit side sensor component 20B are fitted in such a way that the light-emitting surface (one side surface 30A) and the light-receiving surface (one side surface 30B) face each other.

[0041] Then, the light-emitting unit side sensor component 20A and the light-receiving unit side sensor component 20B fitted into the sensor fitting hole H1 are fixed in a position where the light-emitting surface and the light-receiving surface are spaced apart by a predetermined distance (for example, a distance equivalent to the height of the bill passing hole H2) so as to open the bill passing hole H2 of the cartridge 21. In this manner, the light-emitting unit side sensor component 20A and the light-receiving unit side sensor component 20B of the image sensor 20 are fixed to the cartridge 21.

[0042] Methods of fixing the light-emitting unit side sensor part 20A and the light-receiving unit side sensor part 20B at positions spaced a predetermined distance apart while leaving the banknote passing hole H2 include, for example, a method of fixing them by passing screws through screw holes (not shown) provided on the cartridge 21 and the light-emitting unit side sensor part 20A and the light-receiving unit side sensor part 20B, or a method of fixing the light-emitting unit side sensor part 20A and the light-receiving unit side sensor part 20B with an adhesive while a jig (not shown) having a predetermined thickness is sandwiched between the light-emitting unit side sensor part 20A and the light-receiving unit side sensor part 20B. Alternatively, a member that hooks onto the first side surface 41 of the cartridge 21 while being inserted into the sensor insertion hole H1 may be provided on the light-emitting unit side sensor component 20A side, and a member that hooks onto the second side surface 42 of the cartridge 21 while being inserted into the sensor insertion hole H1 may be provided on the light-receiving unit side sensor component 20B side, so that the light-emitting unit side sensor component 20A and the light-receiving unit side sensor component 20B are fixed in a state where they are respectively hooked onto the first side surface 41 and the second side surface 42. The configuration of the validation unit 10 is as described above.

[0043] Next, the configuration of the conveying path R side to which the discriminating unit 10 is attached will be described with reference to Figs. 5 to 8. Here, the configuration of the conveying guide 70 forming the conveying path R will be described as the configuration of the conveying path R side. Fig. 5 is an external perspective view of the conveying guide 70 with the discriminating unit 10 attached. Fig. 6 is a cross-sectional view of the conveying guide 70 with the discriminating unit 10 attached, cut at the center in the width direction of the conveying guide 70. Fig. 7(A) is a one-side view (top view) of the conveying guide 70 with the discriminating unit 10 attached, seen from the light-emitting unit side sensor component 20A side, and Fig. 7(B) is a one-side view (bottom view) of the conveying guide 70 with the discriminating unit 10 attached, seen from the light-receiving unit side sensor component 20B side. Fig. 8 is an external perspective view showing a method of attaching the discriminating unit 10 to the conveying guide 70. In Figs. 5 to 8, the directions related to the conveying guide 70 are defined as the X direction, the Y direction, and the Z direction. 5 to 8, the X direction is the transport direction of the transport path R, the Y direction is the width direction of the transport path R, and the Z direction is the height direction of the transport path R, which correspond to the X direction, Y direction, and Z direction shown in FIGS. 2 to 4, respectively.

[0044] 5 and 6, the conveying guide 70 has a plate-shaped upper conveying guide 70A located at one end (upper side) in the height direction (Z direction) of the conveying path R, and a plate-shaped lower conveying guide 70B located at the other end (lower side) in the height direction (Z direction) of the conveying path R. In other words, the conveying path R is formed between the upper conveying guide 70A and the lower conveying guide 70B. The upper conveying guide 70A and the lower conveying guide 70B are fixed inside the banknote processing device 1 by means not shown.

[0045] As shown in FIG. 5 and FIG. 6 as well as FIG. 7(A), the upper conveying guide 70A is provided with a through hole H10 penetrating the upper conveying guide 70A in the thickness direction (Z direction) at the position where the discriminating unit 10 is attached. The through hole H10 is a hole for fitting the cartridge 21 of the discriminating unit 10, and is hereinafter referred to as the cartridge fitting hole H10. The cartridge fitting hole H10 extends along the width direction (Y direction) of the conveying path R. The length of the cartridge fitting hole H10 in the longitudinal direction (Y direction) parallel to the width direction of the conveying path R is slightly longer than the length of the longitudinal direction (Y direction) of the first side surface 41 of the cartridge 21, and the length of the lateral direction (X direction) parallel to the conveying direction of the conveying path R is slightly longer than the length of the lateral direction (X direction) of the first side surface 41 of the cartridge 21 (a rectangular portion excluding the protrusions 50, 51 and the convex portions 52, 56).

[0046] 7(A), the cartridge insertion hole H10 of the upper transport guide 70A has a wall surface on one end side in the short side direction (X direction) with multiple recesses 72A recessed in the short side direction (X direction) at regular intervals in the long side direction (Y direction) of the cartridge insertion hole H10. The recesses 72A are portions into which the protrusions 52A of the cartridge 21 fit when the cartridge 21 is inserted into the cartridge insertion hole H10, and are slightly larger than the protrusions 52A and are provided at locations facing the protrusions 52A.

[0047] In other words, one end side of the cartridge insertion hole H10 in the short direction (X direction) is provided with an uneven portion 73A in which recesses 72A and protrusions (portions between recesses 72A and 72A) are alternately arranged in the longitudinal direction. This uneven portion 73A forms a nested structure with the uneven portion 53A of the cartridge 21 when the cartridge 21 is inserted into the cartridge insertion hole H10.

[0048] Additionally, the cartridge insertion hole H10 of the upper transport guide 70A has a wall surface on the other end side in the short side direction (X direction) with multiple recesses 76A recessed in the short side direction (-X direction) at regular intervals in the long side direction (Y direction) of the cartridge insertion hole H10. The recesses 76A are portions into which the protrusions 56A of the cartridge 21 fit when the cartridge 21 is inserted into the cartridge insertion hole H10, and are slightly larger than the protrusions 56A and are provided at locations facing the protrusions 56A.

[0049] In other words, the other end side of the cartridge insertion hole H10 in the short direction (X direction) is provided with an uneven portion 77A in which recesses 76A and protrusions (portions between recesses 76A and 76A) are alternately arranged in the longitudinal direction. This uneven portion 77A also forms a nested structure with the uneven portion 57A of the cartridge 21 when the cartridge 21 is inserted into the cartridge insertion hole H10. This nested structure makes it possible to prevent, for example, the leading end portion in the transport direction of the banknote transported along the transport path R from entering a gap formed between the cartridge 21 and the upper transport guide 70A.

[0050] As shown in FIG. 8, the cartridge 21 is inserted into the cartridge insertion hole H10 from above the upper transport guide 70A, and at this time, the protrusions 50, 51, 54, and 55 of the cartridge 21 protrude outside the cartridge insertion hole H10 and come into contact with the upper surface 70As of the upper transport guide 70A.

[0051] 6, the upper transport guide 70A has a chamfered tapered corner 80 of the recess 72A that faces the corner 60 of the protrusion 52A of the cartridge 21 in the transport direction (X direction). Since the corner 60 of the protrusion 52A of the cartridge 21 and the corner 80 of the recess 72A of the upper transport guide 70A that faces the corner 60 have a chamfered tapered shape, the distance between the protrusion 52A and the recess 72A widens toward the transport path R.

[0052] Similarly, the corner 82 of the recess 76A, which faces the corner 62 of the protrusion 56A of the cartridge 21 in the conveying direction (-X direction), is also chamfered and tapered. In this way, the corner 62 of the protrusion 56A of the cartridge 21 and the corner 82 of the recess 76A of the upper conveying guide 70A facing the corner 62 are chamfered and tapered, so that the distance between the protrusion 56A and the recess 76A widens toward the conveying path R. This tapered shape makes it possible to prevent, for example, the leading end of a bill conveyed along the conveying path R from getting caught between the protrusion 52A and the recess 72A or between the protrusion 56A and the recess 76A.

[0053] As shown in FIG. 8, the upper surface 70As of the upper conveying guide 70A is provided with cylindrical bosses 90 and 91 protruding from the upper surface 70As at locations facing the protrusions 50 and 51 located at one end of the cartridge 21 in the short side direction (X direction) when the cartridge 21 is inserted into the cartridge insertion hole H10.

[0054] Furthermore, on the upper surface 70As of the upper conveying guide 70A, screw holes 94 and screw holes 95 are provided at locations facing the protrusions 54 and 55 located on the other end side of the cartridge 21 in the short direction (X direction) when the cartridge 21 is inserted into the cartridge insertion hole H10.

[0055] As will be described in more detail later, the cartridge insertion hole H10, bosses 90, 91, and screw holes 94, 95 provided in the upper conveying guide 70A are intended to fix the cartridge 21 of the discrimination section 10 to the upper conveying guide 70A, and hereinafter these are collectively referred to as the cartridge fixing section.

[0056] On the other hand, as shown in FIGS. 6 and 7B, the lower transport guide 70B has a shape symmetrical to the upper transport guide 70A across the transport path R, except for some parts (bosses 90, 91, screw holes 94, 95).

[0057] That is, the lower conveying guide 70B has a cartridge insertion hole H11 at a position facing the cartridge insertion hole H10 of the upper conveying guide 70A across the conveying path R. Furthermore, the lower conveying guide 70B has a wall surface at one end of the cartridge insertion hole H11 in the short side direction (X direction) with a plurality of recesses 72B recessed in the short side direction (-X direction) at regular intervals in the longitudinal direction (Y direction) of the cartridge insertion hole H11. That is, at one end of the short side direction (X direction) of the cartridge insertion hole H11, an uneven portion 73B is provided in which recesses 72B and protrusions (portions between recesses 72B and recesses 72B) are alternately arranged in the longitudinal direction. The uneven portion 73B forms a nested structure with the uneven portion 53B of the cartridge 21 when the cartridge 21 is inserted into the cartridge insertion hole H11.

[0058] In addition, a plurality of recesses 76B recessed in the short-side direction (-X direction) are provided at regular intervals in the longitudinal direction (Y direction) of the cartridge insertion hole H11 on the wall surface at the other end of the short-side direction (X direction) of the cartridge insertion hole H11. That is, at the other end of the short-side direction (X direction) of the cartridge insertion hole H11, an uneven portion 77B is provided in which the recesses 76B and the protrusions (portions between the recesses 76B and the recesses 76B) are alternately arranged in the longitudinal direction. The uneven portion 77B forms a nested structure with the uneven portion 57B of the cartridge 21 when the cartridge 21 is inserted into the cartridge insertion hole H11. This nested structure makes it possible to prevent, for example, the leading end portion in the transport direction of the banknote transported along the transport path R from entering the gap formed between the cartridge 21 and the lower transport guide 70B.

[0059] 6, the lower conveying guide 70B has a chamfered tapered corner 81 of the recess 72B that faces the corner 61 of the protrusion 52B of the cartridge 21 in the conveying direction (X direction). Similarly, the corner 83 of the recess 76B that faces the corner 63 of the protrusion 56B of the cartridge 21 in the conveying direction (-X direction) also has a chamfered tapered corner. This tapered shape makes it possible to prevent, for example, the leading end of a banknote conveyed along the conveying path R from getting caught between the protrusion 52B and the recess 72B, or between the protrusion 56B and the recess 76B.

[0060] 8, the cartridge 21 is fitted from above the upper transport guide 70A by being pushed into a cartridge fitting hole H10 of the upper transport guide 70A and a cartridge fitting hole H11 (FIG. 7(B)) of the lower transport guide 70B. At this time, the cartridge 21 is positioned by being pushed in until the protrusions 50, 51, 54, 55 come into contact with the upper surface 70As of the upper transport guide 70A so that the bosses 90, 91 provided on the upper surface 70As of the upper transport guide 70A are inserted into the through holes H3, H4 provided in the protrusions 50, 51. As a result, one side of the cartridge 21 (i.e., the light-emitting unit side sensor component 20A side) with the banknote passing hole H2 in between is inserted into the cartridge insertion hole H10 of the upper conveying guide 70A, and the other side (i.e., the light-receiving unit side sensor component 20B side) with the banknote passing hole H2 in between is inserted into the cartridge insertion hole H11 of the lower conveying guide 70B, so that the banknote passing hole H2 is connected to the conveying path R.

[0061] Thereafter, the cartridge 21 is fixed to the upper transport guide 70A by threading the screws 110, 111 through the through holes H5, H6 provided in the protrusions 54, 55 and into the screw holes 94, 95 provided in the top surface 70As of the upper transport guide 70A.

[0062] In this way, when the cartridge 21 is fixed to the upper conveying guide 70A, as shown in Figure 6, the light-emitting unit side sensor component 20A fixed to the cartridge 21 is positioned on the upper conveying guide 70A side (i.e., above the conveying path R), and the light-receiving unit side sensor component 20B is positioned on the lower conveying guide 70B side (i.e., below the conveying path R), and the banknote passing hole H2 located between them is connected to the conveying path R located between the upper conveying guide 70A and the lower conveying guide 70B.

[0063] After the validation unit 10 is fixed to the upper conveying guide 70A, the validation unit 10 is electrically connected to the banknote processing device 1 by connecting cables (not shown) to the connector 32A of the light-emitting unit side sensor component 20A and the connector 32B of the light-receiving unit side sensor component 20B.

[0064] In the validation unit 10, the light emitted from the light-emitting unit side sensor component 20A is received by the light-receiving unit side sensor component 20B, and the banknote is identified based on the light reception result by the light-receiving unit side sensor component 20B when the banknote transported along the transport path R passes through the banknote passing hole H2 (i.e., when it passes between the light-emitting unit side sensor component 20A and the light-receiving unit side sensor component 20B).

[0065] In addition, the validation unit 10 may distinguish banknotes based on the light reception result by the light receiving unit side sensor component 20B, or the light reception result may be sent from the validation unit 10 to a control unit (not shown) of the banknote processing device 1, and the control unit may distinguish banknotes based on the light reception result.

[0066] Furthermore, as shown in Figure 9, the upper conveying guide 70A is rotatably supported by a rotating shaft 120 extending in the width direction of the conveying path R, for example, at a position away from the mounting point of the classification section 10 in the conveying direction, and can be opened and closed around the rotating shaft 120 in the direction away from and toward the lower conveying guide 70B.

[0067] Furthermore, as shown in FIG. 6, since the discrimination unit 10 has a simple structure having only the image sensor 20, the length D1 from the tip of the convex portion 52B provided at one end in the short side direction (X direction) to the convex portion 56B provided at the other end (i.e., the length in the conveying direction of the portion of the entire discrimination unit 10 that is positioned within the conveying path R) can be reduced to, for example, about 40 mm.

[0068] Incidentally, the short-edge length of the smallest Japanese banknote is 76 mm, and the short-edge length of the smallest foreign banknote is 60 mm. Therefore, the validator 10 can make the length D1 of the portion disposed in the transport path R shorter than the short-edge length of the smallest banknote. The transport guide 70 is configured as described above.

[0069] [3. How to remove jammed bills] Next, a brief description will be given of a method for removing jammed banknotes when a jam occurs in the validator 10 or around the validator 10. When the banknote processing device 1 detects that a jam has occurred in the validator 10 or around the validator 10 based on the detection result of a sensor (not shown) provided on the transport path R, for example, the banknote processing device 1 displays this on a display (not shown), for example.

[0070] When, for example, a maintenance worker of the banknote processing device 1 sees this display and realizes that a jam has occurred inside the validator 10 or around the validator 10, he or she accesses the inside of the banknote processing device 1. Then, as shown in Fig. 9, the maintenance worker lifts the upper conveying guide 70A to open the upper conveying guide 70A in a direction away from the lower conveying guide 70B. At this time, naturally, the validator 10 moves away from the lower conveying guide 70B together with the upper conveying guide 70A.

[0071] This exposes the transport path R around the validation unit 10. Here, for example, if a jammed banknote is jammed with part of it inside the validation unit 10 (i.e., inside the banknote passing hole H2 of the cartridge 21), the jammed banknote is removed, for example, by pulling it out from inside the validation unit 10 fixed to the upper transport guide 70A. At this time, as described above, the length D1 (FIG. 6) of the part of the validation unit 10 arranged inside the transport path R in the transport direction is shorter than the short edge direction of the banknote, so that part of the jammed banknote protrudes from the banknote passing hole H2. This allows a maintenance worker to easily remove the jammed banknote from inside the validation unit 10.

[0072] On the other hand, if the jammed banknote is jammed in the transport path R outside the discriminating unit 10, the jammed banknote may be removed from the transport path R.

[0073] After removing the jammed banknote in this manner, the maintenance worker closes the upper transport guide 70A in a direction approaching the lower transport guide 70B, thereby completing the work. The method for removing jammed banknotes when a jam occurs in the validation unit 10 or around the validation unit 10 is as described above.

[0074] [4. Summary and Effects] As described so far, in this embodiment, the banknote processing device 1, which is an example of a medium processing device, is provided with a transport path R for banknotes, which are an example of a medium, a validation unit 10 provided on the transport path R for validating banknotes transported along the transport path R, and a transport guide 70 provided along the transport path R for guiding the banknotes.

[0075] Furthermore, the transport guide 70 is provided with an upper transport guide 70A, which is an example of a first transport guide formed on one side with the transport path R in between, and a lower transport guide 70B, which is an example of a second transport guide formed on the other side with the transport path R in between.

[0076] Furthermore, the validation unit 10 is equipped with a light-emitting unit side sensor component 20A which is an example of a first sensor component, a light-receiving unit side sensor component 20B which is an example of a second sensor component, and a cartridge 21 which is an example of a holding member having a banknote passing hole H2 which is an example of a medium passing hole and which holds the light-emitting unit side sensor component 20A on one side and the light-receiving unit side sensor component 20B on the other side with the banknote passing hole H2 in between.

[0077] The upper conveying guide 70A is provided with a cartridge fixing portion (cartridge insertion hole H10, bosses 90, 91, screw holes 94, 95), which is an example of a fixing portion for fixing the cartridge 21, so that the banknote passing hole H2 of the cartridge 21 is connected to the conveying path R, the light emitting unit side sensor component 20A is positioned on the upper conveying guide 70A side, and the light receiving unit side sensor component 20B is positioned on the lower conveying guide 70B.

[0078] Specifically, the upper conveying guide 70A is provided with a cartridge insertion hole H10, which is an example of a first holding member insertion hole, and the lower conveying guide 70B is provided with a cartridge insertion hole H11, which is an example of a second holding member insertion hole. The cartridge 21 is fixed to the upper conveying guide 70A with screws 110 and 111 in a state in which one side (i.e., the light-emitting unit side sensor component 20A side) of the cartridge 21 is inserted into the cartridge insertion hole H10 of the upper conveying guide 70A with the bill passing hole H2 sandwiched therebetween, and the other side (i.e., the light-receiving unit side sensor component 20B side) of the cartridge 21 is inserted into the cartridge insertion hole H10 of the lower conveying guide 70B with the bill passing hole H2 sandwiched therebetween.

[0079] In this way, the light-emitting unit side sensor part 20A and the light-receiving unit side sensor part 20B of the validation unit 10 are integrated by the cartridge 21, and the validation unit 10 is fixed to the upper conveying guide 70A. Therefore, even if the upper conveying guide 70A is opened and closed relative to the lower conveying guide 70B to remove jammed banknotes inside the validation unit 10, it is possible to prevent the relative positions of the light-emitting unit side sensor part 20A and the light-receiving unit side sensor part 20B from being shifted.

[0080] Thus, according to the banknote processing device 1 of this embodiment, it is possible to prevent deviation in the relative position between the light-emitting unit side sensor component 20A and the light-receiving unit side sensor component 20B. Also, jammed banknotes in the validator 10 can be removed. Also, according to the banknote processing device 1 of this embodiment, since the validator 10 is simply fixed to the upper transport guide 70A with the screws 110, 111, it is possible to easily attach and detach the validator 10 to the upper transport guide 70A. Therefore, in the banknote processing device 1, it is possible to easily handle various banknotes by, for example, replacing the validator 10 depending on the banknote to be handled.

[0081] Furthermore, in this embodiment, by limiting the uses of the banknote processing device 1 to self-service teller machines and the like, and limiting the sensor required for the validation unit 10 to the image sensor 20 alone, the length D1 in the conveying direction (medium conveying direction) of the portion of the validation unit 10 arranged within the conveying path R can be made shorter than the length (76 mm) in the short side direction (medium conveying direction) of the smallest size banknote among those handled by the banknote processing device 1.

[0082] In this way, in the banknote processing device 1, even if a jam occurs, for example, in the banknote passing hole H2 of the validation section 10, part of the jammed banknote protrudes from the banknote passing hole H2, so that the jammed banknote can be easily removed from the validation section 10.

[0083] 5. Other embodiments [5-1. Another embodiment 1] In the above embodiment, the image sensor 20, which is a transmission type optical sensor composed of the light-emitting unit side sensor component 20A and the light-receiving unit side sensor component 20B, is provided in the validator 10. However, the present invention is not limited to this, and a sensor other than the image sensor 20 may be provided as long as it has two sensor components arranged opposite each other with the banknote passing hole H2 connected to the transport path R sandwiched therebetween. For example, a magnetic sensor having a transmitter and a receiver may be provided instead of the image sensor 20. Furthermore, a reflective sensor may be provided instead of a transmission type. Furthermore, the present invention is not limited to this, and a plurality of sensors may be provided in the validator 10.

[0084] 10, for example, the validator 10 may be provided with conveying rollers 200 (200A, 200B) for conveying the bill passing through the bill passing hole H2 along the conveying direction (X direction). In this case, the validator 10 rotatably holds the conveying roller 200A, which is an example of a first conveying roller, and the conveying roller 200B, which is an example of a second conveying roller, arranged opposite to each other across the bill passing hole H2, by the cartridge 21, and rotates one of the conveying rollers 200A and 200B by, for example, a motor (not shown), and drives the other. Note that FIG. 10 shows an example in which pairs of the conveying rollers 200A and 200B are provided near one end side and the other end side of the image sensor 20 fixed to the cartridge 21 in the short side direction (X direction).

[0085] The validator 10 is adapted to adjust the image sensor 20 while passing a banknote through the banknote passing hole H2 before being attached to the banknote processing device 1, and thus providing the transport rollers 200 inside the validator 10 has the advantage that it is not necessary to readjust (fine-tune) the image sensor 20 after attachment because the transport state of the banknote when passing through the banknote passing hole H2 does not change before and after the validator 10 is attached to the banknote processing device 1. In addition, since the relative position between the transport rollers 200A and 200B does not change, there is also the advantage that banknotes can be transported stably.

[0086] [5-2. Other embodiment 2] In the above-described embodiment, a cartridge fixing portion is provided on the upper transport guide 70A side, and the cartridge 21 of the validation unit 10 is fixed to the upper transport guide 70A by the cartridge fixing portion. However, the present invention is not limited to this, and a cartridge fixing portion may be provided on the lower transport guide 70B side, and the cartridge 21 of the validation unit 10 may be fixed to the lower transport guide 70B by the cartridge fixing portion.

[0087] Furthermore, in the above-described embodiment, the cartridge 21 of the discrimination section 10 is fixed to the upper conveying guide 70A using the screws 110 and 111, but this is not limited to the above, and the cartridge 21 may be fixed to the upper conveying guide 70A or the lower conveying guide 70B by a method other than using the screws 110 and 111.

[0088] [5-3. Other embodiment 3] Furthermore, in the embodiment described above, the upper transport guide 70A around the discrimination unit 10 is openable (movable) relative to the lower transport guide 70B, and the upper transport guide 70A is opened while the discrimination unit 10 is fixed to expose the transport path R. However, the present invention is not limited to this, and the upper transport guide 70A may be openable (movable) by a method different from that of the embodiment described above as long as the method can expose the transport path R.

[0089] 11, for example, of the upper transport guide 70A around the discrimination unit 10, a first portion 201 located on one side in the transport direction with the discrimination unit 10 therebetween and a second portion 202 located on the other side may be openable and closable with respect to the lower transport guide 70B, and the transport path R may be exposed by opening the first portion 201 and the second portion 202. In this case, the discrimination unit 10 is fixed to the lower transport guide 70B, for example. However, this is not limiting, and for example, the transport path R may be exposed by opening the lower transport guide 70B with respect to the upper transport guide 70A.

[0090] [5-4. Other embodiment 4] Furthermore, in the above-described embodiment, a connector 32A is provided on the light-emitting unit side sensor component 20A, and a connector 32B is provided on the light-receiving unit side sensor component 20B. For example, after the cartridge 21 having the light-emitting unit side sensor component 20A and the light-receiving unit side sensor component 20B fixed thereto is fixed to the upper conveying guide 70A, a cable (not shown) is connected to the connectors 32A and 32B, thereby electrically connecting the validation unit 10 to the banknote processing device 1.

[0091] Without being limited thereto, for example, a drawer connector (jack-in connector) not shown may be provided on the back surface of the protrusion 50 of the cartridge 21 (the surface facing the upper surface 70As of the upper conveying guide 70A), and a drawer connector may also be provided on the upper surface 70As of the upper conveying guide 70A at a location facing the protrusion 50 of the cartridge 21. In this case, when the cartridge 21 is pushed into and fitted into the cartridge fitting hole H10 of the upper conveying guide 70A, the drawer connectors are connected to each other, and the validation unit 10 is electrically connected to the banknote processing device 1.

[0092] In this case, for example, the drawer connector on the upper conveying guide 70A side is electrically connected to the banknote processing device 1, and the drawer connector on the cartridge 21 side is electrically connected to the light-emitting unit side sensor component 20A and the light-receiving unit side sensor component 20B.

[0093] [5-5. Other embodiment 5] Furthermore, in the above-described embodiment, the present invention is applied to a banknote processing device 1 that handles banknotes, but the present invention is not limited to this and can also be applied to a media processing device that handles media other than banknotes (e.g., tickets, coupons, gift certificates, checks, etc.).

[0094] [5-6. Other embodiment 6] Furthermore, the present invention is not limited to the above-mentioned embodiment and other embodiments, that is, the scope of application of the present invention extends to embodiments in which the above-mentioned embodiment and other embodiments are combined in part or in whole in any manner, or embodiments in which parts are extracted. [Industrial Applicability]
