Description

  TECHNICAL FIELD The present invention relates to improvements in intermediary machines such as rental machines arranged between game machines in game halls such as pachinko halls and pachislot halls, and in particular, accommodates banknotes that are installed and inserted in each intercalation machine. It is related with improvement of a thin bill handling device.

In game halls such as pachinko halls and pachislot halls, a machine for lending game balls and game medals is installed in a narrow space (40 to 60 mm) between game machines. The inter-machine is provided with a bill insertion slot and operation buttons on the front surface, and a player who wants to play a game on an adjacent gaming table can insert a bill from the bill insertion slot and then operate with the operation button. A desired number of game balls and medals can be borrowed.
The old pedestal machine itself does not have means for storing banknotes, and banknotes inserted into the pedestal machine are transported using transport means arranged on the amusement island, and the banknotes are stored in a large storage box. A large-scale system was housed in the house. However, with such a system configuration, the configuration of the amusement island including the transport means becomes large and complicated, leading to an increase in cost. Therefore, improvement of this point has been demanded.
On the other hand, banknote storage type intermediary machines equipped with a stacker for storing banknotes in individual interbank machines have become commonplace recently, and when the stacker is full, staff members are prohibited from opening and closing the stacker. The operation for unlocking the lock and taking out the banknote bundle is appropriately performed.
The bill storage type inter-bed machine has a bill discriminator for judging the authenticity and denomination of the accepted bill and a bill that has been judged to be a genuine bill by the bill discriminator in the inner part of the bill insertion slot. Stackers for receiving and stacking are sequentially arranged, and both are integrated. When the banknotes stored in the stacker are full, it is necessary to pull out the banknote discriminator and the stacker forward, open the stacker, and take out the banknotes.
Japanese Patent Laid-Open No. 2002-924 discloses a configuration in which a banknote identification device and a stacker are simultaneously drawn forward from the interframe machine body in the horizontal direction, and an opening provided on a side surface of the stacker is opened to take out an internal banknote bundle. It is disclosed.
However, since it is necessary to carry out the work of taking out the full banknote even while the player is playing on the adjacent game stand, the opening provided on the side surface of the stacker is opened and the internal When the work of taking out the banknote bundle is performed, the player's arm and body come into contact with the player sitting at the most recent position, which disturbs the game. In addition, regardless of the presence or absence of a player, it is complicated to take out the banknotes stored inside from the side opening of the stacker that is pulled forward, and when inserting a finger into the opening, the fingers are placed with gears or sheet metal. There is a risk that the banknote may be injured, the banknote may be bent, or the banknote may be left behind. In order to solve such a problem, Japanese Patent Application Laid-Open Nos. 2002-35401 and 2002-163703 make it possible to bend only the front half of the stacker part so that it can be easily taken out from the side. Although the technology is disclosed, there is a problem that the configuration is complicated due to the relation with the bill storage mechanism in the stacker.

On the other hand, in JP-A-2002-263354, a bill discriminator and a stacker are configured separately, and the bill discriminator and the stacker are configured to be able to be drawn forward in the horizontal direction from the inter-machine main body. The rear lower part of the identification machine and the lower front part of the stacker are pivotally supported by a hinge part, so that only the banknote identification machine is rotated and retracted downward in the state where both are pulled out, and the front surface of the stacker is opened. An apparatus is disclosed. Since the end portion of the stored banknote bundle is exposed on the opened front surface of the stacker, the banknote bundle can be easily taken out by an operation from the front.
However, in this conventional example, it is necessary to perform a two-action operation in which the banknote discriminator and the stacker are integrally pulled out forward in the horizontal direction and then only the banknote discriminator is rotated downward to be opened. It was.
In addition, the conventional stacker stacker employs a mechanism that pushes the pusher back and forth in order to stack the banknotes drawn into the stacker on the banknote receiving plate, thus ensuring a movable range of the pusher. For this reason, there is a problem that the storage space for bills is reduced and the number of stored bills is reduced.
Japanese Patent Application Laid-Open No. 57-67451 discloses two opposite edges of a bill conveyed in a stacker by rotatably arranging a plurality of multiple spirals on the bill stacking side of a bill receiving plate. Is supported between the pitches of each multi-winding spiral, and the multi-winding spiral is rotated in a predetermined direction so that the bill edge is sequentially transferred onto the banknote receiving plate along the pitch. Is disclosed. According to this, since a pusher that requires a large movable range is not required, it is possible to increase the number of banknotes accommodated within a limited width. However, in this conventional example, it is necessary to arrange at least four multiple winding spirals in a limited narrow space stacker and also to arrange the driving mechanism of each multiple winding spiral. There is a disadvantage that it increases and the structure becomes complicated. In addition, when a deformed banknote such as a folded bag or a bag enters, the edge of the banknote may not normally enter between the pitches of all the multiple spirals. In addition, in the state where all the drawn banknotes are completely transferred onto the banknote receiving plate, the uppermost banknote surface is pressed at the end of the multiwinding spiral, so the axial length of the multiwinding spiral is There is a drawback that the number of stored bills is reduced by that amount. In particular, the multiple winding spiral is configured to be capable of increasing the processing speed by simultaneously holding five or more bills by each multiple winding spiral by using multiple windings of five or more windings. Therefore, the number of bills stacked on the bill receiving plate is reduced by that amount.
Next, in Japanese Patent Laid-Open No. 11-232526, a single spiral is rotatably arranged in a banknote storage box, and one end edge in the width direction of the banknote introduced along the longitudinal direction in the storage box is defined as a spiral. A configuration is disclosed in which the sheet is transferred onto a banknote receiving plate sandwiched between pitches.
However, since this conventional example is configured to guide one edge of the bill in the width direction by a single spiral, it is possible to transfer a deformed bill on which a folded fold or a ridge is formed with good alignment on the bill receiving plate. difficult.

FIG. 7 is a schematic diagram for explaining a banknote conveying means. FIG.
In FIG. 1, the machine 1 is configured to be thin because it is installed in a narrow space of about 40 mm between game machines such as pachinko machines in a game hall such as a pachinko hall. The intermediary machine 1 includes an intermediary machine main body 2 provided with a storage and payout mechanism for rental balls, a bill identification unit 10 for identifying the authenticity and denomination of a bill inserted from the insertion slot 12, and a bill identification unit 10 , A stacker 30 that stores bills that have passed through the stack, a mounting unit 3 that is a space for storing the bill recognition unit 10 and the stacker 30 in a front-rear positional relationship, and a control unit.
The mounting unit 3, the banknote recognition unit 10, and the stacker 30 constitute a banknote handling device D, and the mounting unit 3, the banknote recognition unit 10, and the stacker 30 include the housing of the banknote handling device D and other mechanism members. It is supported by the frame which comprises.
Control means for controlling the mounting unit 3, the bill identifying unit 10, and the stacker 30 may be mounted on the bill handling apparatus D side.
The mounting portion 3 is disposed at an appropriate position of the inter-table machine main body 2 (a height position that is easy to operate for a player sitting in front of an adjacent gaming table). The mounting portion 3 is an open space on the front side, and a stacker 30 as an independent unit is accommodated in the back thereof so as to be able to advance and retract in the front-rear direction. ), A bill recognition unit 10 as an independent unit is pivotally supported so as to be opened and closed (rotated) in the vertical direction by a hinge portion 11 provided at the lower portion of the mounting portion (the lower portion of the frame body of the bill handling device D). The front end surface of the part 10 is provided with a vertically long bill insertion slot 12. Further, the bill recognition unit 10 and the stacker 30 are connected by a link 13 (pull rod) so that the stacker 30 advances and retreats back and forth in the mounting unit 3 in conjunction with the opening / closing operation by the rotation of the bill recognition unit 10.

For this reason, the stacker 30 is pulled forward via the link (link mechanism) 13 so that the stored banknote bundle can be easily taken out.
In the present invention, it is possible to realize the transition to the banknote collection state by a single operation of gripping and rotating the banknote recognition unit 10 at the time of banknote collection. There is no need to hold and pull out the. Or conventionally, since the stacker could not be pulled out from the mounting portion even if the identification portion was rotated, and the banknotes were taken out by inserting the hand into the back of the mounting portion, the operability was extremely poor. On the other hand, according to the present invention, since the stacker part is pulled out to the front part of the mounting part by one action in conjunction with the opening operation of the identification part, the operability is improved.
The locking means 14 is latched by a plate member 14a fixed to the front surface of the banknote recognition unit 10, a lock portion 14b provided at an end of the plate member 14a, and a locking piece 14b ′ provided in the lock portion 14b.

It can shift to the state of FIG.2 (b) by locking and rotating the banknote identification part 10 below. Here, by arranging the spring urging means on the hinge portion as described above, it is possible to shift to the banknote collection state only by removing the lock and performing no special operation.
The banknote recognition unit 10 includes an identification sensor 20 and a conveying means (belt and roller) 15 which will be described later in its casing, and is provided in a control means (not shown) provided in the inter-machine main body 1 or a banknote handling device D. The control means (stacker printed circuit board 54) (not shown) determines the authenticity and denomination based on the detection signal from the identification sensor 20 arranged in the bill movement path while the bill inserted from the insertion slot 12 is drawn inside by the transport means 15. When it is necessary to reject, the conveying means 15 is reversed and returned from the insertion port 12, and when it is received, it is conveyed to the stacker 30 side.

The rod-shaped link 13 is pivotally supported at the front end by a pin at the lower rear portion of the bill recognition unit 10 and the rear end is pivotally supported by a pin at an appropriate position of the stacker 30. Therefore, as shown in FIGS. The behavior as shown is possible. Reference numeral 16 denotes a cable for electrically connecting the bill recognition unit 10 and the stacker 30, 16 a is a cable guide, and 17 is a motor for driving the conveying means 15. Further, a door 18 that can be opened and closed in the direction of the arrow as shown in FIG. 5 is provided on the side surface of the casing of the banknote recognition unit 10, and the door is opened with the banknote recognition unit opened as shown in FIG. And the inside of the casing can be inspected.
The stacker 30 is supported by a guide (not shown) provided above and below the mounting portion 3 so as to be able to advance and retract in the front-rear direction. The stacker 30 includes a casing 33 having an accommodation space 32 for receiving a bill that has passed through the bill recognition unit 10 from the front opening 31, and a pair of upper and lower portions that are rotatably arranged at predetermined vertical intervals inside the front opening of the casing 33. Spiral members 35, 36, a drive mechanism 46 including a motor 40 and gear groups 41, 42, 43, 44, 45 for synchronously rotating and driving the two spiral members; And a belt 50 as a retracting means for retracting to the stop position.
The gear groups 41 to 45 constituting the drive mechanism 46 are rotationally driven by a dedicated motor 40. On the other hand, the belt 50 is connected to the output shaft 55a of the motor 55 dedicated to driving the belt and the shaft 56a of the pulley 56 that drives the belt 50 by a worm gear in the gear box 57. Driven by transmission.
The two spiral members 35, 36 are integrated with shaft portions 35a, 36a extending in the horizontal direction and spirally wound around the respective shaft portions 35a, 36a, and have the same pitch and opposite spiral directions. Spiral blades 35b and 36b extending to the right are provided. Further, the shaft center portions of the large-diameter gears 41 (first gear) and 42 (second gear) are fixed to the tip portions of the shaft portions 35a and 36a.

The spiral member is made of a resin material that is easy to process with low friction such as polyacetal.
Each spiral blade 35b, 36b is wound in 1.5 layers (1.5 rolls). As shown in FIGS. 6A and 6B, the spiral blades 35b, 36b correspond in the initial state of accepting bills. Are stopped at a rotation angle at which both edges of the banknote B can be inserted in the same pitch (same height position). That is, the banknote B shown by the solid line in FIG. 6A is supported on one side by the belt 50 while being guided within the pitch of the spiral blades 35b and 36b, and is fed back on the banknote receiving plate 51, and the leading edge of the banknote is The belt 50 stops in contact with the wall 52. When the bills are stopped, the spiral blades 35b and 36b are in the initial state shown in FIGS. 6A and 6B and stopped, but the spiral members 35 and 36 immediately start to rotate in the direction of the arrow in FIG. Therefore, both end portions in the width direction of the banknote located between the pitches move in the axial direction along the pitch, that is, toward the banknote receiving plate 51 side, and detach from the end portions 35b ′ and 36b ′ of the spiral blades 35b and 36b. Then, after sitting on the banknote receiving plate 51, the outer side surface of the banknote is pressed by the bottom surfaces (end surfaces, pressing surfaces) of the terminal portions 35b ′ and 36b ′ of the spiral blades.
The rotation direction of each spiral member when the banknotes held within the pitch of each spiral blade are transferred onto the banknote receiving plate 51 is the direction in which the rear end of the banknote is extended outward in the width direction as shown in FIG. It is preferable to set as follows. By comprising in this way, the banknote with a wrinkle shrink | contracted inside the width direction can be extended | stretched to the width direction outer side.
When accepting the next bill, each spiral member 35, 36 returns to the initial state (home position) shown in FIGS. 6A and 6B and stands by.

The detection that the spiral members 35 and 36 are at the illustrated home positions is provided on a detection plate 39a provided on one end (opposite side of the banknote pressing surface) of the shaft portions 35a and 36a of the spiral members, for example. This is performed by detecting a detection hole or the like by the photo interrupter 39b (FIG. 11).
In the present invention, the number of turns of the spiral blades 35b, 36b constituting each spiral member 35, 36 may be 1.5 folds, i.e., less than 2 turns, so that the axial length can be minimized. The number of banknotes accommodated in the stacker can be increased as compared with the prior art.
In the present invention, the spiral members 35 and 36 serve as a bill guide at the home position shown in FIG. 6A, and after the inserted bill is conveyed to the back wall 52 and stopped, (C) As shown in (d), the bills are stacked (transferred) on the preceding stack bills by detaching both end edges of the bills held by each spiral member once from the terminal end of the pitch. Since the trailing edge of the banknote is suppressed, the accumulated banknotes are not lifted up, and a collision between the already inserted banknote and the newly inserted banknote is prevented.

Next, with reference to FIG. 7, a schematic configuration of the banknote recognition unit and banknote conveying means in the stacker will be described. The banknote recognition unit 10 is disposed so as to face the belt 15a and a belt 15a that form a transport path between the guide plate 21 biased in one direction (in the banknote thickness direction) by the spring 22 and one side of the guide plate 21. The bank 15 inserted from the insertion slot 12 can be conveyed in the direction of the stacker 30 or can be sent back to the insertion slot 12 by driving the belt 15a forward and backward by the motor 17.
On the stacker 30 side, a banknote receiving plate 51 urged in one direction (belt 50 side) by a spring 53, a belt 50 arranged on the banknote stacking surface side of the banknote receiving plate 51 to introduce banknotes, and a spiral member 35, 36, etc. As described above, the spiral members 35 and 36 stop at the home position (angle) so that the bills conveyed on the guide plate 21 of the bill recognition unit 10 can be received and guided in the pitch of the spiral blades when the bills are introduced. The fed banknote is conveyed further by the belt 50 toward the back on the banknote receiving plate 51 and is conveyed until the front end of the banknote comes into contact with the back wall (stacker abutting portion) 52 to drive the belt 50. To stop. When the belt 50 is stopped, the spiral members 35 and 36 are each rotated by a predetermined angle in the direction of the arrow in FIG. 5 to seat the rear end portion of the banknote held in the pitch on the stacking surface of the banknote receiving plate 51 and The side surface is pressed by the lower surface in the vicinity of the end portions 35b 'and 36b' of the spiral blade. Since the banknote receiving plate 51 is also urged toward the belt by the spring 53, the banknote (bundle) transferred onto the banknote receiving plate 51 is surely secured by the banknote receiving plate 51 and the lower end surface of each spiral blade. Retained.
3 and 4, reference numeral 54 denotes a stacker printed circuit board housed in an appropriate place in the stacker casing 33 (in this example, the lower part of the casing), and a circuit for controlling each driving element constituting the stacker. It is installed.
Further, a notch 61 is formed on the front opening edge of the bill cover 60 located inside the stacker casing 33 so that the bill bundle can be easily taken out. An opening 33a and a lid 33b for opening and closing the opening 33a are arranged on the side surface of the casing 33. Opening the lid 33b facilitates the removal of dust attached to the conveying means exposed to the inside, the accommodating portion, the removal of jammed bills, and the cleaning of the belt.

Next, another feature of the present invention resides in the arrangement of gears 41 to 45 constituting the drive mechanism 46. That is, the drive mechanism 46 includes large-diameter gears 41 (first gear) and 42 (second gear) that are coaxially fixed to one end in the axial direction of the spiral members 35 and 36, and both large-diameter gears. The two small-diameter gears 43 (third gear) and 44 (fourth gear), which are disposed between the large-diameter gears 41 and located between the large-diameter gears and transmit driving force, mesh with one large-diameter gear 41. The two small-diameter gears 43 and 44 are disposed so as to be retracted farther than the two large-diameter gears 41 and 42. That is, the spiral members 35 and 36 are configured to have different spiral directions, and are synchronously rotated in opposite directions.
In addition, the diameter dimension of each gear 41-44 can be arbitrarily set by the relationship with a layout with a peripheral component, the 1st and 2nd gear is a large diameter, and the 3rd, 4th gear is a small diameter. It is not always necessary.
The reason why the large-diameter gears 41 and 42 are connected by the two small-diameter gears 43 and 44 is to transmit power while adjusting the rotation direction in one part. By arranging the positions of 43 and 44 behind the notch 61 for taking out banknotes provided at the front part of the banknote cover 60, the banknotes exposed from the notch 61 are not obstructed when taken out by the fingertips. It is to make it. That is, if the large-diameter gears 41 and 42 are similarly connected by one large-diameter gear, the notch 61 is blocked by the third large-diameter gear, and thus the two small-diameter gears 43 and 44 are connected. By using this, it is possible to dispose it at the back of the notch 61.
Next, FIG. 8 is a main part explanatory view showing an example of the mounting structure of the gear group in the stacker casing. That is, in the stacker casing 33, the banknote cover 60 is disposed so as to surround a part or the front part of the banknote storage part. In this embodiment, the banknote cover 60 is large inside the banknote cover 60 (the banknote storage part side). While the radial gears 41 and 42 are arranged, the two small-diameter gears 43 and 44 are arranged in the recess 60 a outside the banknote cover 60. Furthermore, the wall 60b is provided in the front side of this recess 60a, and the danger that a finger | toe contacts the small diameter gears 43 and 44 when taking out a banknote from the notch 61 is avoided. The small diameter gears 43 and 44 in the recess 60a and the large diameter gears 41 and 42 located inside the banknote cover are meshed with each other through an opening 60a ′ provided in the recess 60a.

Next, both end surfaces in the axial direction of the spiral members 35 and 36 of the above-described embodiment are surfaces that are curved and inclined as shown in FIG. 6A (non-flat surfaces and surfaces that are not parallel to the banknote surface). Therefore, when the upper surface of the banknotes stacked on the banknote receiving plate 51 is pressed by the terminal portions of the spiral members 35 and 36, they cannot be pressed closely by surface contact over a wide range, and the spiral It tends to be in a state where it is pressed linearly at the edge (outer peripheral edge) of the member end portion or in a state where it is pressed in a narrow surface contact centered on the edge. For this reason, the area to be pressed becomes insufficient, and the pressing force is not sufficiently applied to the banknote surface, and slipping easily occurs. For this reason, the trouble which the banknote which detach | leaved from the pitch termination | terminus part of each spiral member to the banknote receiving plate 51 side returns in the pitch between spiral members again generate | occur | produces, and a collision with a subsequent banknote becomes easy to occur. Such inconvenience is that the bill presser portion located at the end of each spiral member is a non-flat surface that is curved and inclined, and that the number of turns of the entire spiral member is too small (less than 1.5 turns). There is a cause.
Moreover, in the spiral members 35 and 36 of the above-described embodiment, since both end surfaces in the axial direction are not orthogonal to the shaft portion and are inclined, the pitch width between the blades for receiving the leading edge of the bill to be introduced is small. There is also a problem of narrowing (described later).
FIGS. 9A to 9E are configuration explanatory views of a spiral member according to another embodiment of the present invention that can solve the above-mentioned problems at once, and FIG. 9A is a perspective view, and FIG. (C) is a left side view, (d) is an A view of (c), and (e) is a bottom view. FIGS. 10A and 10B are explanatory views of each flat surface.
The spiral blades 35b and 36b constituting the spiral members 35 and 36 in the present embodiment are provided with flat surfaces 37a and 37b perpendicular to the axial direction at both ends in the axial direction over a relatively wide angular range, respectively. A configuration in which the flat surfaces 37a and 37b are connected by a spiral inclined surface 38 is provided. Each flat surface 37a, 37b is a surface parallel to the upper surface of the banknote receiving plate 51 or the upper surface of the banknote on the banknote receiving plate 51.
In addition, the axial direction dimension (full axial direction length) of the spiral member of the said embodiment and the spiral member of this embodiment is equivalent. The above problems can be solved all at once by improving the configuration in which the number of turns of the spiral blade and the shape of both ends in the axial direction are changed while the axial dimensions are set to be equal.

In the present embodiment, the number of spiral turns X of each of the spiral blades 35b and 36b is set in a range of 1.5 turns ≦ X <2.5 turns (in this example, 1.83 turns). The angle range of 37a and 37b is secured sufficiently wide. For example, in the present embodiment, the central angle of the flat surface 37b on the terminal end side that holds down the upper surface of the banknote (bundle) placed on the banknote receiving plate 51 is 180 degrees or more and 340 degrees or less (300 degrees in this example). The central angle of the other flat surface 37a is not particularly limited. By setting the number of spiral turns X to a predetermined range of 1.5 turns or more, each flat surface can be secured over such a wide angular range. If the number of spiral turns X is set to less than 1.5, it is difficult to sufficiently secure the flat surface 37b for holding the bill. Actually, it is only necessary to secure a gap through which bills can pass between the flat surfaces 37a and 37b, and the central angle of the flat surface 37b depends on the dimension between the flat surfaces.
Thus, in the present embodiment, since the spiral winding number X of each spiral blade 35b, 36b is set in the range of 1.5 windings ≦ X <2.5 windings, the central angle range of the flat surface 37b on the terminal end side is set to It becomes possible to ensure a wide area, and the upper surface of the banknote completely transferred onto the banknote receiving plate 51 by the flat surface 37b having a large area in the circumferential direction can be surely kept pressed by a sufficient surface pressure. Therefore, the problem that a slip occurs between the holding part of the spiral blade and the bill and the bill returns to the pitch of the spiral blade is solved.
Moreover, since the edge part on the opposite side to the flat surface 37b as a press part was also made into the flat surface 37a, since the linear contact | abutting with respect to the banknote by the edge of the flat surface 37a is eliminated, it becomes a surface presser, Not only can the presser force be dispersed to prevent the banknote from being deformed, but the banknote located between the pitches of the spiral blades is flat even if the banknote is curled up by the edge of the banknote or folded up. 37a can hold down and correct this, and banknotes can be prevented from remaining in the pitch of the spiral blades.

Next, another merit of making the end portion of the spiral blade into a flat surface 37b having a large area is that the spiral member is stopped slightly at the stop position in the standby state (home position) shown in FIGS. Even if the direction deviation occurs, the circumferential angle of the flat surface 37b extends over a wide range exceeding 180 degrees, so that it is always possible to sufficiently ensure the pitch for receiving the banknote (the axial interval between the blades). It is possible to prevent the situation that the leading edge of the bill entering from the direction of the arrow hits the inclined surface 38 and cannot proceed to the back.
In other words, since each spiral member according to the embodiment of FIGS. 6 and 9 has a limited axial dimension, the axial space in which bills can enter between the spiral blades is the axis of the spiral member. Unlike the spiral blade of the embodiment shown in FIG. 6 and the like, the spiral blade of the present embodiment has flat surfaces 37a and 37b at both ends. Can be secured widely.
FIGS. 10A and 10B are schematic diagrams for explaining this, and both the spiral members have a constant axial length. As shown in FIG. 10 (a), in the spiral members 35 and 36 having flat surfaces 37a and 37b at both axial ends of the spiral members 35b and 36b, an entry space for receiving the bill B entering from the arrow direction is provided. The width W1 can be ensured as wide as the distance H between the flat surfaces. On the other hand, as shown in FIG. 10B, in the type in which both ends of the spiral member are inclined, the width W2 of the bill entry space is narrow.
Thus, according to the embodiment of FIG. 9, it is possible to maximize the width of the entry space, and even if there is a deformation such as a bend at the tip of the inserted bill, the space between the spiral pitches can be stably maintained with sufficient margin. Can lead to. On the other hand, since the entry space is narrow in the spiral member of FIG. 10B, the allowable entry range for the bending deformation of the tip of the inserted bill is narrowed.

Next, in the spiral member according to the embodiment of FIG. 9, since it is possible to secure a wide allowable entry angle range when waiting for a bill at the home position, it is not necessary to strictly detect and align the home position. There is an advantage that it can be done. That is, for example, when the spiral members 35 and 36 stand by at the home position shown in FIGS. 9 (a) and 9 (b) and wait for receipt of a bill, the home position detection is fixed to one end of the shaft portions 35a and 36a. This is performed by detecting a notch provided in a disc-shaped detection plate 39a (not shown) by a photo interrupter 39b (see FIG. 11). Depending on the detection sensitivity of the home position detection means, the spiral member is stopped at the home position. The angle varies. In the spiral member according to the embodiment of FIG. 6, as described with reference to FIG. 10B, since the bill entry space width W <b> 2 of the spiral blade is narrow, the angle between the regular home position and the actual stop angle. If the difference becomes large, the leading edge of the banknote that has entered will interfere with the inclined portion of the spiral blade, making it impossible to enter.
On the other hand, in the embodiment of FIG. 9, since the entry space width W1 is wide, the range of the angle difference that allows entry is increased, and the spiral member shown in FIG. Even if a positional deviation within ± 90 degrees from the position occurs, the bill can smoothly pass through the entry space without being interfered by the inclined portion 38.

Next, in the drive mechanism 46 of the embodiment shown in FIGS. 3, 4, and 5, the large-diameter gears 41 and 42 (the first gear 41 and the second gear) integrated with the spiral members 35 and 36, respectively. 42) and small-diameter gears 43 and 44 (third gear 43 and fourth gear) meshed with the respective large-diameter gears 41 and 42 are rotated by a dedicated motor 40, while banknotes are stored in the accommodation space 32. The belt 50 as the pull-in means for pulling to the stop position is separately driven by a drive mechanism including the motor 5, the gear box 57, the pulley 56, and the like. However, driving the two drive mechanisms provided close to each other by separate drive mechanisms brings about problems such as an increase in installation space and an increase in the number of parts.
FIG. 11 shows an embodiment according to a shared drive mechanism for solving such a problem.
In other words, the present embodiment is characterized in that a common motor 70 that drives the two spiral members 35 and 36 to rotate in the forward and reverse directions is also used as a drive source for the belt 50 as a pull-in means. When the common motor rotates in the forward direction, the spiral members 35 and 36 rotate in a direction in which the trailing edge of the banknote is guided and pressed on the receiving plate 51, while transmission of the driving force to the belt 50 is interrupted. That is, the spiral members 35 and 36 are not reversed when the common motor is reversed. Further, when the common motor 70 rotates in the reverse direction, the reverse driving force is transmitted only to the belt 50 side, and the driving force transmission to the spiral members 35 and 36 is interrupted. That is, the forward driving force is not transmitted to the belt 50 during the forward rotation of the common motor.
That is, in the drive mechanism according to this embodiment, the large-diameter gears 41 and 42 integrated with the spiral members 35 and 36, the small-diameter gears 43 and 44 disposed between the large-diameter gears 41 and 42, and 2 When the two transmission gears 45a and 45b are engaged with each other in the order shown in the drawing, the transmission gears 45a and 45b are rotationally driven by the output gear 70b provided at the tip of the output shaft 70a of the common motor 70 that can be rotated forward and backward. The transmission gear 45a and the output gear 70b are composed of worm gears or bevel gears. For example, a one-way clutch is arranged on the shaft portion of the transmission gear 45a to drive forward rotation from a common motor only in one direction indicated by an arrow. The force is transmitted. This one direction coincides with the direction of rotation for transferring the rear end portion of the bill held between the pitches of the spiral blades by rotating the spiral members 35 and 36 in the direction of the arrow, onto the receiving plate 51. Therefore, when the common motor rotates in the reverse direction, the driving force is not transmitted to the gears 45a, 45b, 41, 43, 44, 42.
On the other hand, the belt 50 is stretched by two front and rear pulleys 56, and a driven pulley 56b for driving force transmission is fixed to one end of the shaft 56a of the rear pulley 56 and is connected to the output shaft 70a of the common motor. The drive pulley 56c is connected by a transmission belt (not shown). Since the worm gears 70c meshing with each other are arranged in the middle of the shaft of the drive pulley 56c and the output shaft 70a of the common motor 70, the driving force from the output shaft 70a is driven by the drive pulley 56c, the transmission belt, and the driven pulley 56b. , And transmitted to the shaft 56a and the pulley 56, the belt 50 is driven in the retracting direction. Note that a one-way clutch is also arranged on the shaft portion of the drive pulley 56c so that the belt 50 is rotationally driven only in the pull-in direction. The rotation direction of the common motor 70 when driving the belt 50 in the pull-in direction is set opposite to the direction in which the spiral members 35 and 36 are driven to rotate in the one direction, and each one-way is set in the middle of each driving force transmission path. By arranging the clutch, an alternative driving force transmission structure can be realized.

The common motor 70 may be driven to rotate in one direction and the rotation direction may be switched by a clutch (not shown). However, the configuration is complicated and the size is increased by the arrangement of the clutch.
Thus, the motor that rotationally drives the two spiral members synchronously is used as a drive source for the pull-in means, and the drive is configured to selectively realize the drive of the spiral member and the drive of the pull-in means. Since the mechanism is provided, the number of motors can be reduced to achieve downsizing and cost reduction.
In addition, by applying the banknote handling apparatus of the present invention to a game machine pedestrian machine in a game hall where a pachinko machine, a pachislot machine, etc. are installed, an excellent effect can be obtained.
