[1-2. Configuration of switching inversion unit]
As shown in FIGS. 3, 4, and 5, the switching and reversing unit 17 is separated into an upper unit 17 </ b> A located on the upper side and a lower unit 17 </ b> B located on the lower side along the conveyance path formed inside. It is configured to be possible.

  3 is a perspective view of the switching reversing unit 17 as viewed from the upper left front, FIG. 4 is a perspective view of the switching reversing unit 17 as viewed from the lower left front, and FIG. 5 is a perspective view of the switching reversing unit 17 from the left. FIG. 3 to 5 and the following drawings, for convenience of explanation, parts of the upper unit 17A and the lower unit 17B are partially simplified or omitted.

  The lower unit 17B is configured around the base 31. The base 31 has a shape along the conveyance path, a conveyance guide that guides the banknote, a roller that advances the banknote by rotating, a transmission mechanism such as a gear and a shaft that transmits driving force to the roller, or a banknote An optical sensor or the like for detecting the presence or absence of this is incorporated.

  As shown in FIG. 5, the base 31 has first bearings 31 </ b> A on the left and right sides of the conveyance path at the upper rear side, and has a second bearing 31 </ b> B only on the left side of the conveyance path at the lower front side. A third bearing 31C is provided on each of the left and right sides of the conveyance path on the lower rear side of the two bearings. Incidentally, each of the first bearing 31A, the second bearing 31B, and the third bearing 31C is a round hole drilled with the central axis directed in the left-right direction.

  The upper unit 17A is configured around the upper frame 32. The upper frame 32 is attached with a conveyance guide, a roller, a transmission mechanism, an optical sensor, and the like (all not shown) having a shape opposite to the conveyance guide of the base 31. Also, on the front side of the upper frame 32, a front / back reversing unit 17F (FIG. 5) for reversing the front and back of a bill is attached. For this reason, the weight of the upper unit 17A becomes relatively large when all of these components and units are attached.

  As shown in FIGS. 6A, 6B, and 6C, the upper frame 32 is formed, for example, by cutting and bending a thin metal plate into a predetermined shape. The upper frame 32 is roughly composed of a substrate 32A, and a left side plate 32B and a right side plate 32C that are suspended downward from the left and right sides of the substrate 32A.

  The substrate 32A is configured in a thin plate shape in the vertical direction, and the front side portion and the rear side portion at the center of the left and right are greatly squeezed. The various components and units described above are attached to the lower surface of the substrate 32A.

  The left side plate 32B is suspended downward from the left side of the substrate 32A, and is formed in a thin plate shape that is long in the front-rear direction with the plate surface directed in the left-right direction. An insertion hole 32BH penetrating in the left-right direction is formed in the vicinity of the rear end of the left side plate 32B. In addition, a columnar post 33 that is short in the left direction is erected on the lower side of the front side of the insertion hole 32BH in the left side plate 32B.

  The right side plate 32C extends downward from the right side of the substrate 32A, and is formed in a thin plate shape that is long in the front-rear direction with the plate surface facing in the left-right direction, like the left side plate 32B. In the vicinity of the rear end of the right side plate 32C, an insertion hole 32CH penetrating in the left-right direction is formed at a position corresponding to the insertion hole 32BH of the left side plate 32B.

  Further, a supported portion 32CJ is provided on the front side of the insertion hole 32CH in the right side plate 32C so as to extend downward. The supported portion 32CJ is formed in a trapezoidal shape having a long upper base and a short lower bottom, and is curved so that a lower end 32CK corresponding to the lower bottom portion protrudes downward. In addition, a concave portion 32CM having a shape that is bent upward is formed near the upper end of the hypotenuse 32CL corresponding to the front leg in the trapezoid.

  The upper frame 32 passes through the insertion hole 32BH of the left side plate 32B, the two first bearings 31A (FIG. 5) in the base body 31, and the insertion hole 32CH of the right side plate 32C in order, so as to have a long and narrow cylindrical first. It is inserted through the rotation shaft 34 (FIG. 6A). Incidentally, the first rotation shaft 34 corresponds to the rotation shaft 17R shown in FIG.

  Thereby, the upper frame 32 is pulled away from the base 31 so that the front side is lifted from the base 31 with the first rotary shaft 34 as the center of rotation (the counterclockwise direction in FIG. 5 and indicated by the arrow R1). It is possible to rotate in the opposite direction, that is, the direction in which the front side is lowered to approach the base 31 (also indicated by the arrow R2).

  A stay 35 shown in FIGS. 7A and 7B is provided on the left side of the left side plate 32B in the upper frame 32. Incidentally, FIG. 7A is a perspective view seen from the upper front left oblique side, and FIG. 7B is a left side view.

  The stay 35 has a thin plate shape with the plate surface directed in the left-right direction as a whole, and is configured around a substrate 35A formed in a triangular shape when viewed from the left-right direction. Reinforcing portions 35B and 35C are suspended from the upper side and the front lower side of the substrate 35A toward the left side. Further, three holes such as an insertion hole 35K, a guide hole 35L, and a link hole 35M are formed in the substrate 35A so as to penetrate in the left-right direction.

  The insertion hole 35K is a round hole and is provided near the center of the front lower side of the substrate 35A. The stay 35 is inserted with an elongated cylindrical second rotation shaft 36 so as to pass through the insertion hole 35K and the second bearing 31B (FIG. 5) of the base 31.

  Thereby, the stay 35 is lifted upward with the second rotation shaft 36 as the rotation center with respect to the base 31 (the clockwise direction in FIG. 5 and indicated by the arrow S1), and the opposite direction. That is, it can be rotated in the direction in which the rear side is lowered downward (similarly indicated by the arrow S2).

  The guide hole 35L is a long hole that is generally long in the front-rear direction, and is curved so as to protrude upward. Hereinafter, for convenience of explanation, a virtual center line in the longitudinal direction of the guide hole 35L is referred to as a virtual center line GL (FIG. 7B).

  The virtual center line GL has an angle that is nearly vertical in the range from the foremost point P1 to the vicinity of the point P2 that is approximately in the middle of the front and rear, and is horizontal in the range from the vicinity of the point P2 to the rearmost point P3. The angle is close. In other words, the guide hole 35L is formed so as to pass through a plurality of points P1, P2, and P3 having different distances as viewed from the insertion hole 35K.

  The guide hole 35L is connected to a support hole 35N that is a relatively short long hole at the point P3 that is the rear end thereof. The support hole 35N is formed so that its long axis is directed to the front lower side from the connection point with the guide hole 35L. As for the support hole 35N, similarly to the guide hole 35L, if the virtual center line in the longitudinal direction is the virtual center line GN, the point P4 that is the end of the virtual center line GN is located in front of and below the point P3. ing.

  A post 33 erected on the left side plate 32B of the upper frame 32 is inserted through the guide hole 35L. For this reason, when the upper frame 32 rotates about the first rotation shaft 34, the stay 35 receives the force from the post 33 that rotates together with the upper frame 32 on the inner surface of the guide hole 35L, and the second It rotates around the rotation shaft 36. At this time, the post 33 moves along the virtual center line GL or GN in the guide hole 35L or the support hole 35N (details will be described later).

  The link hole 35M is formed in a rectangular shape when viewed from the left-right direction, and the direction connecting the front lower side and the rear upper side is the longitudinal direction. In other words, the link hole 35M has its longitudinal direction generally aligned with the radial direction centered on the insertion hole 35K.

  A counter shaft 37 shown in FIG. 8 is inserted into the left and right third bearings 31 </ b> C in the base 31. Similar to the first rotation shaft 34, the counter shaft 37 is configured in an elongated cylindrical shape with the central axis directed in the left-right direction. Therefore, the countershaft 37 can freely rotate or rotate with respect to the base body 31 around the third bearing 31C.

  In addition to the central part 37A formed in a general columnar shape, the countershaft 37 is formed in a planar shape substantially partially parallel to the central axis by cutting off part of its peripheral side surface in the vicinity of both left and right ends. The formed attachment surfaces 37B and 37C are provided, respectively.

  A spring 38 made of a torsion spring is inserted through the counter shaft 37. As shown in FIG. 9, the spring 38 is configured around a wound portion 38 </ b> A that is spirally wound in the same manner as a general coil spring. When the winding portion 38A is inserted through the countershaft 37, the spring 38 is in a state where its central axis is directed in the left-right direction.

  A first engagement that extends in a direction away from the central axis on the left end side of the spring 38, is bent in the left direction, travels substantially parallel to the central axis, and is bent in the direction toward the central axis again. A portion 38B is provided. The right end side of the spring 38 is provided with a second engaging portion 38C that extends in a direction away from the central axis and is then curved in an annular shape that makes a round around the central axis substantially parallel to the central axis. Yes. Incidentally, the second engaging portion 38 </ b> C is fixed to the base 31, thereby preventing the entire spring 38 from spinning around the counter shaft 37.

  A link body 39 shown in FIG. 10 is attached to the left end of the counter shaft 37 (FIG. 8). The link body 39 includes a mounting plate 39A made of a square thin plate, a fixed plate 39B suspended from the left side thereof, and a link plate 39C suspended from the right side of the mounting plate 39A.

  The fixed plate 39B is a square thin plate having the same size as the mounting plate 39A. The fixing plate 39B is provided with a square hole-shaped insertion hole 39BH penetrating in the left-right direction. One side of the insertion hole 39BH overlaps with a joint portion between the fixed plate 39B and the mounting plate 39A.

  The link plate 39C is a rectangular thin plate having a larger area than the mounting plate 39A. That is, the length of each side in the link plate 39C is about the same as that of the fixed plate 39B with respect to the normal direction of the mounting plate 39A, and about two to three times as long as the fixed plate 39B with respect to the direction intersecting this. It has become.

  In the link plate 39C, an insertion hole 39CH having a rectangular shape similar to that of the insertion hole 39BH is formed at a position that is substantially right of the insertion hole 39BH of the fixing plate 39B. In the link body 39, the right end portion of the counter shaft 37 (FIG. 6) is sequentially inserted into the insertion hole 39CH of the link plate 39C and the insertion hole 39BH of the fixed plate 39B, so that the mounting surface 37B is the plate of the mounting plate 39A. The surface is brought into contact with the surface. In this state, the link body 39 is fixed to the counter shaft 37 with a mounting screw (not shown) or the like, and is integrated with the counter shaft 37.

  As a result, the link body 39 is rotated counterclockwise (indicated by an arrow T1 in FIG. 5 (B)) with respect to the base body 31 with the counter shaft 37 as the rotation center, as viewed from the left side, or in the clockwise direction (the opposite direction). Similarly, it can be turned to the direction indicated by arrow T2.

  Further, a link shaft 40 is erected at a position away from the insertion hole 39CH on the right surface of the link plate 39C. In the link shaft 40, the left side portion of the columnar member with the central axis directed in the left-right direction is sharply cut, so that a pedestal portion 40P on the right side with a thick and short columnar shape and a shaft portion 40S on the left side with a thin and long columnar shape. The shape is such that and are joined.

  The link shaft 40 is attached to the link plate 39C via the pedestal portion 40P, and the shaft portion 40S is inserted into the link hole 35M of the stay 35 (FIG. 7). Therefore, when an external force is applied to the stay 35 and the link body 39 rotates about the second rotation shaft 36, this force is transmitted via the link hole 35 </ b> M and the link shaft 40, and the counter shaft 37 is rotated about the center of rotation. Rotate as Further, when the force is applied and the link body 39 rotates about the counter shaft 37 as the rotation center, this force is transmitted through the link shaft 40 and the link hole 35M. As a result, the stay 35 is rotated.

  Further, the link plate 39C of the link body 39 has a first engaging portion of the spring 38 against a contact side 39CE which is a side connected to the mounting plate 39A (a lower side in FIG. 10B). 38B (FIG. 9) engages. Here, the spring 38 urges the link body 39 to rotate in the direction of the arrow T1 (FIG. 5) by the action of elastic force. Since this elastic force is transmitted through the link shaft 40 and the link hole 35M, the stay 35 is biased in the direction of rotating in the arrow S1 direction.

  On the other hand, a support body 41 is attached to the right end of the countershaft 37 (FIG. 6). The support body 41 is roughly divided into an attachment plate 41A corresponding to the attachment plate 39A of the link body 39, and a support plate 41B suspended from the right side thereof.

  The mounting plate 41A is formed in a square thin plate shape like the mounting plate 39A (FIG. 9) of the link body 39, and a reinforcing portion for increasing the strength is extended along the connecting portion with the support plate 41B. ing.

  The support plate 41B is a rectangular thin plate having a larger area than the mounting plate 41A. That is, the support plate 41B has a length in the direction intersecting with the length of the mounting plate 41A in the normal direction of about 3 to 4 times. Incidentally, the length of the support plate 41B in the longitudinal direction is sufficiently longer than the length of the side of the stay 35 where the reinforcing portion 35B is provided.

  The support plate 41B is provided with an insertion hole 41BH having a square hole shape similar to the insertion hole 39CH in the link plate 39C of the link body 39 (FIG. 8). One side of the insertion hole 41BH overlaps with a joint portion between the support plate 41B and the mounting plate 41A.

  A bent portion 41C that is bent in a crank shape when viewed from the normal direction of the mounting plate 41A is formed in the vicinity of the end portion of the support plate 41B that is separated from the insertion hole 41BH. Further, a contact portion 41E is attached to a tip portion 41D farther than the bent portion 41C when viewed from the insertion hole 41BH in the support plate 41B. The contact portion 41E is formed in a short columnar shape with the central axis directed in the left-right direction.

  The support body 41 is brought into a state in which the mounting surface 37C is in contact with the plate surface of the mounting plate 41A by inserting the right end portion of the counter shaft 37 (FIG. 8) into the insertion hole 41BH of the supporting plate 41B. In this state, the support body 41 is fixed to the countershaft 37 with a mounting screw (not shown) or the like, thereby being integrated with the countershaft 37 and the link body 39 as shown in FIG. Hereinafter, the integrated counter shaft 37, the link body 39 and the support body 41, and the link shaft 40 provided on the link body 39 are collectively referred to as a support rotation portion 43.

  As a result, the support rotation unit 43 has the counter shaft 37 as a rotation center, and is counterclockwise (in the direction of the arrow T1 in FIG. 5B) as viewed from the left side or in the clockwise direction (in FIG. 5B). It can be rotated in the direction of arrow T2 in B).

  As described above, the switching and reversing unit 17 is based on the base 31, the upper frame 32 that rotates about the first rotation shaft 34, the stay 35 that rotates about the second rotation shaft 36, and the countershaft. The support rotation part 43 in which the link body 39 and the support body 41 are integrated at both ends of 37 can be rotated while being interlocked with each other.

[1-3. Opening and closing operation]
Next, an operation of opening / closing the upper unit 17A with respect to the lower unit 17B in the switching / reversing unit 17, that is, a rotating operation of rotating the upper frame 32 with respect to the base 31 will be described.

  As shown in FIG. 5, the switching and reversing unit 17 is in a state where the upper unit 17 </ b> A is closed as shown in FIG. 5, and the upper frame 32 is brought close to the base body 31 (hereinafter referred to as a closed state). It shall be. Incidentally, this state is, for example, when the banknote depositing / dispensing machine 10 (FIG. 2) in which the switching reversing unit 17 is incorporated is just pulled out of the casing 2 (FIG. 1), or when the banknote depositing / dispensing machine 10 is the casing 2. This corresponds to the case of being stored inside and operating based on the control of the bill control unit 12.

  In this closed state, the board 32A (FIG. 6) of the upper frame 32 has its plate surface substantially horizontal. The stay 35 has the plate surface of the reinforcing portion 35B oriented substantially horizontally. The post 33 is at the most forward position in the guide hole 35L, that is, at the point P1 in FIG. Further, the support rotating portion 43 tilts the longitudinal direction of the support body 41 slightly forward from right above, and positions the contact portion 41E in the concave portion 32CM (FIG. 6) of the right side plate 32C in the upper frame 32. It is pulled away from the plate 32C.

  At this time, the spring 38 biases the link body 39 with respect to the base body 31, that is, the whole support rotation portion 43 in the direction of rotating the arrow T <b> 1 by the action of the elastic force. This force is transmitted to the stay 35 via the link shaft 40 and the link hole 35M erected on the link body 39, and biases the stay 35 in the direction of the arrow S1, that is, in the direction of lifting upward. Become.

  However, the post 33 erected on the upper frame 32 is positioned in the guide hole 35L of the stay 35 so that the lower surface of the post 33 is in contact with the guide hole 35L. As described above, the weight of the upper unit 17A in which the post 33 and the upper frame 32 constitute a part is relatively large. For this reason, the stay 35 does not lift the entire upper unit 17A via the post 33, and the rotation in the direction of the arrow S1 is restricted by the post 33, and the position is maintained.

  Next, the switching reversing unit 17 is applied with an external force directed upward by the maintenance worker or the like with respect to the upper unit 17A. Thereby, as shown in FIG. 13 corresponding to FIG. 5, the upper unit 17A rotates the upper frame 32 in the direction of the arrow R1 with the first rotation shaft 34 as the rotation center, thereby lower unit 17B (FIG. 5). It is pulled away from.

  At this time, since the post 33 rotates about the first rotation shaft 34 integrally with the upper frame 32, a force is applied to lift the upper side with respect to the inner surface of the guide hole 35L in the stay 35, and the second The stay 35 is rotated in the direction of the arrow S1 with the rotation shaft 36 as a rotation center, and moves backward in the guide hole 35L, that is, in the directions of the points P2 to P3 (FIG. 7B). .

  The stay 35 rotates the link hole 35M in the direction of the arrow S1, moves the link shaft 40 inserted through the link hole 35M rearward and upward, and uses the counter shaft 37 as a rotation center. Is rotated in the direction of arrow T1.

  Incidentally, as described above, the virtual center line GL of the guide hole 35L has an inclination angle that is nearly vertical in the first half of the range from the point P1 to the point P2 in FIG. For this reason, the stay 35 allows the post 33 to escape slightly upward while the post 33 is positioned in the first half portion, so that the rotation amount in the direction of the arrow S1 is smaller than the rotation amount of the upper frame 32. suppress. Accordingly, the rotation amount of the support rotation portion 43 is also relatively small in the arrow T1 direction. That is, the stay 35 and the support rotation part 43 rotate slowly as compared with the upper frame 32.

  Thereafter, when an external force is applied upward to the upper unit 17A by a maintenance worker or the like, the switching / reversing unit 17 rotates the first rotation shaft 34 as shown in FIG. 14 corresponding to FIGS. The upper frame 32 is further rotated in the arrow R1 direction as a moving center.

  At this time, the stay 35 rotates in the arrow S1 direction when the post 33 lifts the inner surface of the guide hole 35L, and accordingly, the support rotating portion 43 is moved in the arrow T1 direction via the link hole 35M and the link shaft 40. Turn to. As a result, the post 33 moves to the uppermost rear position in the guide hole 35L, that is, the position of the point P3 in FIG. 7B.

  As described above, the guide hole 35L has a virtual center when the stay 35 is in the closed state (FIGS. 5 and 7B) in the latter half of the range from the point P2 to the point P3 in FIG. The line GL has an inclination angle close to horizontal. For this reason, the stay 35 rotates in the direction of the arrow S1 as compared with the amount of rotation of the upper frame 32 by actively moving the post 33 backward while the post 33 is positioned in the latter half. Increase dynamics. Accordingly, the support rotation unit 43 also increases the rotation amount in the arrow T1 direction. In other words, the stay 35 and the support rotation unit 43 rotate more quickly than the upper frame 32.

  At this time, the contact portion 41E of the support rotation portion 43 rotates in the direction of arrow T1 as a part of the support rotation portion 43, and is slightly away from the lower end 32CK of the supported portion 32CJ of the upper frame 32. To reach.

  Finally, the switching reversing unit 17 is loosened by the maintenance worker or the like from the upward external force with respect to the upper unit 17A. Accordingly, as shown in FIG. 15 corresponding to FIGS. 5, 13, and 14, the upper frame 32 rotates slightly downward, that is, in the direction of the arrow R <b> 2 together with the supported portion 32 </ b> CJ.

  Here, the spring 38 (FIG. 8) continuously exerts an elastic force, and urges the support rotating portion 43 in the direction of the arrow T1 and urges the stay 35 in the direction of the arrow S1. For this reason, the stay 35 slightly rotates in the direction of the arrow S1 so as to change the path of the post 33 from the guide hole 35L into the support hole 35N.

  As a result, the post 33 moves from the point P3 in FIG. 7B to the point P4 in the support hole 35N, and is closest to the point P4, that is, the lowermost part of the support hole 35N and the second rotation shaft 36. At the place, the support hole 35N is supported in contact with the lower inner surface. As a result, the upper unit 17 </ b> A including the upper frame 32 is in a state where the left side portion thereof is supported by the stay 35 via the post 33.

  In addition, the support rotation portion 43 slightly rotates in the arrow T1 direction together with the contact portion 41E that is a part of the stay 35 as the stay 35 slightly rotates in the arrow S1 direction. As a result, as shown in FIG. 16, the support body 41 causes the contact portion 41E to contact the lower end 32CK of the supported portion 32CJ of the upper frame 32, and the right side portion of the upper frame 32 via the lower end 32CK. That is, the right side portion of the upper unit 17A is supported from the lower side.

  At this time, in the switching and reversing unit 17, the direction in which the upper frame 32 tries to rotate by the action of gravity is the direction of the arrow R 2 (FIG. 15), but the counter shaft 37 that is the center of rotation of the support body 41 A virtual straight line VL connecting the contact portion 41E is approximately the tangential direction of the virtual circle VC with the first rotation shaft 34 as the center.

  For this reason, in the switching reversing unit 17, when the upper frame 32 applies a force in the direction of the arrow R2 due to its own weight, the support body 41 does not rotate around the counter shaft 37, that is, escapes. It can be received and supported without any problems.

  As described above, the upper unit 17A of the switching and reversing unit 17 is in contact with the post 33 supported by the support hole 35N of the stay 35 on the left side and the supported portion 32CJ of the upper frame 32 attached to the support body 41 on the right side. It is supported by the portion 41E (FIGS. 15 and 16). Hereinafter, this state is referred to as an open state.

  Incidentally, when the upper unit 17A is again brought close to the lower unit 17B, that is, when the upper unit 17A is closed, the switching reversing unit 17 causes the maintenance unit or the like to lift the upper unit 17A to the state shown in FIG. By lowering the upper unit 17A while applying a force in the S2 direction, it is possible to return to the closed state of FIG. 5 through the state of FIG.

[1-4. Effect]
In the above configuration, the switching and reversing unit 17 according to the first embodiment rotates the stay 35 by moving the post 33 in the guide hole 35L as the upper frame 32 rotates. In addition, the switching reversing unit 17 rotates the support rotating unit 43 in conjunction with the stay 35 by moving the link shaft 40 in the link hole 35M.

  When the upper frame 32 is in the open state (FIGS. 15 and 16), the switching and reversing unit 17 positions the post 33 in the support hole 35N of the stay 35 on the left side portion thereof, thereby allowing the upper unit 32 to move to the upper unit. The left part of 17A is supported.

  Further, at this time, the switching reversing unit 17 positions the contact portion 41E attached to the support body 41 rearward and upward with respect to the counter shaft 37 that is the rotation center of the support body 41, and the right side plate 32C of the upper frame 32. It is made to contact | abut to the lower end 32CK of the to-be-supported part 32CJ formed in this. That is, the switching and reversing unit 17 supports the right side portion of the upper unit 17 </ b> A by the support body 41.

  As a result, the switching and reversing unit 17 moves the upper unit 17A, to which the heavy parts such as the front / back reversing unit 17F (FIG. 5) are attached, from the lower unit 17B in an open state (FIGS. 15 and 16). It can be supported stably from both.

  As a result, the switching reversing unit 17 can avoid the occurrence of torsion of the upper unit 17A relative to the lower unit 17B, distortion of the upper unit 17A itself, and the like that may occur when the upper unit 17A is supported from only one of the left and right sides. Thereby, the switching inversion part 17 can prevent the fall of the conveyance precision of a banknote, and the fall of various detection ability beforehand.

  In particular, the switching and reversing unit 17 is configured to be smaller than the stay 35 even when there is little space in the right side portion and a stay having a symmetrical shape with the stay 35 cannot be provided and rotated. By providing the support body 41, the upper unit 17A can be supported from the right side portion only in the open state.

  Further, the support body 41 supports the supported portion 32 </ b> CJ provided at a location relatively close to the first rotation shaft 34 in the upper frame 32 at a location relatively close to the first rotation shaft 34. As a result, in the open state (FIGS. 15 and 16), the switching and reversing unit 17 can be opened over a wide range without blocking the front side portion and the front side portion on the left and right sides with a support member or the like. The workability and efficiency of maintenance work on the lower side of 32 and the upper side of the base 31 can be improved.

  Further, the switching reversing unit 17 curved the guide hole 35L formed in the stay 35 so as to be convex upward (FIG. 7B). That is, when the post 33 is positioned in the range from the point P1 that is the front portion of the guide hole 35L to the vicinity of the point P2, the switching and reversing unit 17 suppresses the rotation amount of the stay 35 to be smaller than the rotation amount of the upper frame 32. Can do. Accordingly, the switching and reversing unit 17 can also suppress the rotation amount of the support body 41 of the support rotation unit 43 and the contact portion 41E provided at the tip thereof in the arrow T1 direction.

  As a result, when the upper frame 32 is close to the closed state, the switching and reversing unit 17 suppresses the amount of rotation of the support body 41 and the abutting portion 41E to make it interfere with the concave portion 32CM, the hypotenuse 32CL, and the like of the upper frame 32. Can be prevented.

  On the other hand, the switching reversing unit 17 increases the rotation amount of the stay 35 relative to the rotation amount of the upper frame 32 when the post 33 is located in the range from the vicinity of the point P2 which is the rear portion of the guide hole 35L to the point P3. Can be made. Accordingly, the switching and reversing unit 17 can also increase the amount of rotation of the support body 41 of the support rotation unit 43 and the contact portion 41E provided at the tip thereof in the arrow T1 direction.

  Thereby, in the switching reversing unit 17, when the upper frame 32 is close to the open state, the rotation amount of the support body 41 and the contact portion 41E is greatly expanded, and is near the lower end 32CK of the supported portion 32CJ of the upper frame 32. Can be reached.

  Further, in the switching reversing unit 17, the spring 38 always applies a force that rotates in the direction of the arrow T1 to the support rotation unit 43, and then the support hole 35N is moved to the arrow S2 side of the guide hole 35L, that is, the stay. The post 35 is formed on the side that can guide the post 33 when it rotates in the direction of the arrow S1.

  Here, it is assumed that a stay 85 is provided in place of the stay 35 and the spring 38 is omitted, as in a virtual switching and reversing unit 77 shown in FIG. On the stay 85, opposite to the stay 35, a support hole 85N is provided on the arrow S1 side with respect to the guide hole 85L, that is, on the side where the post 33 can be guided when the stay 85 rotates in the arrow S2 direction. Yes. Incidentally, FIG. 17 shows a state immediately before the upper frame 32 is lifted up most as a state close to FIG.

  In the switching and reversing portion 77, when the upper frame 32 is further lifted from the state of FIG. 17 and then slightly lowered, as shown in FIG. 18, the stay 85 rotates in the direction of arrow S2 by its own weight, and the post 33 is supported. It will be in the state supported by the hole 85N. At this time, the support rotation portion 43 rotates in the arrow T2 direction as the stay 85 rotates in the arrow S2 direction.

  As described above, in the switching and reversing portion 77, the upper frame 32 is lifted from the closed state and moved to the uppermost position while moving the post 33 without the guide hole 85L, and then slightly lowered to place the post 33 in the support hole 85N. (FIG. 18). During this time, after the support body 41 and the contact portion 41E are rotated in the direction of the arrow T1, the support body 41 and the contact portion 41E finally return slightly in the direction of the arrow T2.

  That is, the switching reversal unit 77 is ideal when the post 33 is positioned in the guide hole 85L in FIGS. 17 and 18 in which the right side plate 32C of the upper frame 32 has substantially the same rotation angle with respect to the horizontal direction ( In FIG. 17), it is desirable to avoid interference with the contact portion 41E, and on the other hand, when the post 33 is located in the support hole 85N (FIG. 18), it is desirable to contact and support the contact portion 41E.

  However, the switching reversing unit 77 makes the contact portion 41E contact the supported portion 32CJ of the right side plate 32C in the state during the opening / closing operation shown in FIG. 17, while in the opening / closing state shown in FIG. 41E is pulled away from the supported portion 32CJ of the right side plate 32C. That is, in a configuration such as the switching inversion portion 77, it is extremely difficult to realize an ideal relationship between the supported portion 32CJ and the contact portion 41E.

  On the other hand, in the switching and reversing unit 17, a force that rotates in the direction of the arrow T1 is always applied to the support rotation unit 43 by the spring 38, and then the support hole 35N is moved to the arrow S2 side of the guide hole 35L. That is, the post 35 is formed on the side where the post 33 can be guided when the stay 35 rotates in the direction of the arrow S1.

  As a result, when the switching reversing unit 17 shifts the upper frame 32 from the closed state to the opened state, the post 33 moves from the point P1 (FIG. 7B) in the guide hole 35L through the points P2 and P3 to the support hole 35N. It is only necessary to rotate the stay 35 only in the direction of the arrow S1 while moving to the inner point P4. At this time, the support rotation unit 43 only needs to rotate in the direction of the arrow T1, and there is no need to switch back in the direction of the arrow T2 as in the switching inversion unit 77 (FIGS. 17 and 18).

  That is, in the switching reversing unit 17, when the support body 41 and the contact portion 41E are rotated to the most arrow T1 side, the contact portion 41E is brought into contact with the lower end 32CK of the supported portion 32CJ of the right side plate 32C in the upper frame 32. It is sufficient to design the shape of the supported portion 32CJ so that it does not contact until then, and can be easily realized.

  According to the above configuration, when the upper frame 32 is lifted in the direction of the arrow R1, the switching reversing unit 17 according to the first embodiment stays while moving the post 33 along the guide hole 35L and the support hole 35N. 35 is rotated in the direction of arrow S1. Accordingly, the support rotation portion 43 is rotated in the direction of arrow T1 by the link shaft 40 inserted through the link hole 35M, and the contact portion 41E of the support body 41 is supported by the supported portion 32CJ of the right side plate 32C in the upper frame 32. Abut. Thereby, the switching reversing unit 17 can stably support the upper unit 17A in the open state from both the left and right sides.

[2. Second Embodiment]
The automatic teller machine 101 (FIG. 1) by 2nd Embodiment has the banknote depositing / withdrawing machine 110 replaced with the banknote depositing / withdrawing machine 10 compared with the automatic teller machine 1 by 1st Embodiment. However, the other parts are configured similarly.

  The banknote depositing / dispensing machine 110 is different from the banknote depositing / dispensing machine 10 according to the first embodiment in that it has a switching inversion unit 117 instead of the switching inversion unit 17, but the other parts are configured similarly. Has been.

[2-1. Configuration of switching inversion unit]
As shown in FIG. 19 partially corresponding to FIG. 3, the switching inversion unit 117 is configured such that the upper unit 117A on the upper side is higher than the lower unit 117B on the lower side, like the switching inversion unit 17 according to the first embodiment. It can be opened by turning.

  Compared with the switching inversion unit 17 according to the first embodiment, the switching inversion unit 117 is configured in the same manner with respect to the base 31, the upper frame 32, the post 33, and the first rotation shaft 34. The parts have different configurations.

  A stay 135 that replaces the stay 35 is provided on the left side of the upper frame 32. Compared to the stay 35 (FIG. 7), the stay 135 is configured in the same manner with respect to the other portions, although the link hole 35M is omitted and the gear portion 135G is provided. The gear portion 135G is formed in a gear shape centered on the insertion hole 35K.

  A spring 138 corresponding to the spring 38 in the first embodiment is inserted through the second rotation shaft 36 that is the rotation center of the stay 135. As in the first embodiment (FIG. 5), the spring 138 urges the stay 135 in the arrow S1 direction.

  However, in the closed state (FIG. 19), the stay 135 is rotated in the direction of arrow S1 by the post 33 erected on the upper frame 32 of the heavy upper unit 117A in the same manner as the stay 35 according to the first embodiment. Is regulated and maintains its position.

  On the lower front side of the upper frame 32, a transmission unit 140 that transmits driving force to the left and right is provided. The left portion of the transmission unit 140 is configured around the rotation shaft 141. The rotating shaft 141 is formed in an elongated cylindrical shape with the central axis facing the front-rear direction, and the worm gear 142 is inserted through a portion almost directly below the gear portion 135G of the stay 135, and the pulley 143 is inserted further forward. ing. The rotating shaft 141 is rotatably supported by a bearing (not shown), and can rotate integrally with the worm gear 142 and the pulley 143.

  The worm gear 142 is meshed with the gear portion 135 </ b> G of the stay 135. Therefore, when the stay 135 rotates about the second rotation shaft 36, the transmission unit 140 rotates the worm gear 142 together with the rotation shaft 141 and the pulley 143 due to the engagement between the gear unit 135 </ b> G and the worm gear 142.

  On the other hand, the right portion of the transmission unit 140 includes a rotation shaft 144, a worm gear 145, and a pulley 146 similar to the left rotation shaft 141, worm gear 142, and pulley 143. A belt 147 is stretched between the pulley 143 and the pulley 146 so as to go around both.

  When the pulley 143 rotates integrally with the rotary shaft 141 and the worm gear 142 on the left side, the transmission unit 140 causes the belt 147 stretched over the pulley 143 to travel, and accordingly, the right pulley 146 is moved to the rotary shaft 144 and the worm gear. 145 and rotate together.

  That is, when the worm gear 142 is rotated on the left side, the transmission unit 140 can transmit the rotation through the rotation shaft 141, the belt 147, and the rotation shaft 144 in order, and rotate the right worm gear 145.

  As shown in FIG. 20A, a support body 148 is provided above the right worm gear 145. The support 148 is formed in a plate shape that is long in the front-rear direction as a whole, and is positioned almost directly below the right side plate 32 </ b> C in the upper frame 32. Incidentally, FIG. 20A schematically shows a state in which the right side portion in the switching inversion unit 117 is viewed from the left direction.

  The support body 148 has holes 148 </ b> H that are formed as long holes penetrating in the left-right direction and having the longitudinal direction in the front-rear direction at two positions in the front-rear direction. Small hole-shaped movement restricting portions 149 erected on the base 31 (FIG. 5) are inserted through the holes 148H. For this reason, the support 148 has a movement range restricted by the relationship between the movement restricting portion 149 and the hole 148H, and can move only in the front-rear direction. In other words, even if an external force is applied from the upper side, the support body 148 can support this without moving downward.

  An abutting portion 148A that protrudes upward from the periphery is formed behind the center of the upper portion of the support 148. When the upper frame 32 is in the closed state as shown in FIGS. 19 and 20A, the upper end 148B that is the upper end portion of the contact portion 148A is higher than the lower end 32CK of the supported portion 32CJ. At this time, the abutting portion 148A is located in front of the supported portion 32CJ.

  A rack 148 </ b> R is formed in a lower part of the support body 148 substantially at the front of the center. The rack 148R is engaged with the worm gear 145. For this reason, when the worm gear 145 rotates integrally with the rotating shaft 144, the support 148 can move back and forth by meshing with the worm gear 145. That is, the transmission unit 140 can transmit the driving force generated by the rotation of the stay 135 on the left side to the right side to move the support body 148 in the front-rear direction.

  In this way, the switching and reversing unit 117 transmits the force generated by the rotation of the stay 135 around the second rotation shaft 36 via the transmission unit 140, and moves the support body 148 in the front-rear direction. Yes.

[2-2. Opening and closing operation]
Next, an operation of opening / closing the upper unit 117A with respect to the lower unit 117B in the switching / reversing unit 117, that is, an opening / closing operation of rotating the upper frame 32 with respect to the base 31 will be described.

  As shown in FIG. 19, the switching / reversing unit 117 is in a state in which the upper unit 117 </ b> A is closed, and is in a state in which the upper frame 32 is brought close to the base 31 (that is, in a closed state). At this time, the post 33 is located at the foremost point Q1 in the guide hole 135L of the stay 135, as in the first embodiment. Further, as shown in FIG. 20A, the support body 148 is located at a front position in the movable range.

  When the upper unit 117A is lifted, the switching / reversing unit 117 rotates the upper frame 32 in the direction of the arrow R1 about the first rotation shaft 34 as in the first embodiment, as in the first embodiment. Pull away from 117B.

  At this time, the post 33 rotates about the first rotation shaft 34 integrally with the upper frame 32. As a result, the post 133 applies a force that lifts upward against the inner surface of the guide hole 135L in the stay 135, and rotates the stay 135 in the arrow S1 direction with the second rotation shaft 36 as the rotation center. However, it moves backward in the guide hole 135L.

  The stay 135 rotates the left worm gear 142 meshed with the gear portion 135G to rotate the gear portion 135G, and transmits the rotation to the right worm gear 145 by the transmission portion 140. The worm gear 145 rotates in a predetermined direction to apply a force that travels backward to the racks 148 </ b> R that are engaged with each other. Thereby, the support body 148 moves backward.

  After that, the post 33 moves to the rearmost side in the guide hole 135L, and then moves into the support hole 135N when the force for lifting the upper unit 117A is loosened. As in the case shown in FIG. It will be in the state supported by 135N.

  At this time, on the right side of the switching / reversing unit 117, as shown in FIG. 20B corresponding to FIG. 20A, the support member 148 is directly below the supported portion 32CJ of the right side plate 32C of the upper frame 32. While the contact portion 148A enters, the upper frame 32 slightly rotates in the direction of the arrow R2, thereby bringing the lower end 32CK of the supported portion 32CJ into contact with the upper end 148B of the contact portion 148A.

  Thus, in the upper unit 117A of the switching reversing unit 117, the post 33 is supported by the support hole 135N of the stay 135 on the left side, and the supported portion 32CJ of the upper frame 32 is supported by the contact portion 148A of the support body 148 on the right side. It becomes the released state.

[2-3. Effect]
In the above configuration, the switching and reversing unit 117 according to the second embodiment rotates the stay 135 by moving the post 33 within the guide hole 135L as the upper frame 32 rotates. Further, the switching reversing unit 117 transmits the rotation of the stay 135 to the worm gear 142 of the transmission unit 140 by the gear unit 135G, and acts on the support 148 from the worm gear 145 of the transmission unit 140 as a force in the front-rear direction. .

  When the upper frame 32 is in the open state, the switching reversing unit 117 positions the post 33 in the support hole 135N of the stay 135 in the left side portion as in the first embodiment (FIG. 15). The stay 135 supports the left side portion of the upper unit 117A.

  Further, the switching reversing unit 117 moves the support body 148 rearward so that the upper end 148B of the contact portion 148A contacts the lower end 32CK of the supported portion 32CJ formed on the right side plate 32C of the upper frame 32. That is, the switching reversing unit 117 supports the right side portion of the upper unit 117 </ b> A by the contact portion 148 </ b> A of the support body 148. As a result, similarly to the first embodiment, the switching and reversing unit 117 can stably support the upper unit 117A, to which a heavy component is attached, from both the left and right sides as an open state lifted from the lower unit 117B. .

  In other respects, the switching inversion unit 117 according to the second embodiment can achieve the same effects as the switching inversion unit 17 according to the first embodiment.

  According to the above configuration, when the upper frame 32 is lifted in the direction of the arrow R1, the switching reversing unit 117 according to the second embodiment stays while moving the post 33 along the guide hole 135L and the support hole 135N. 135 is rotated in the direction of arrow S1. Along with this, the transmission unit 140 transmits the rotation of the gear unit 135G to the support body 148 and moves it backward, and places the contact portion 148A in contact with the lower portion of the supported portion 32CJ. Thereby, the switching reversing unit 117 can stably support the upper unit 117A in the open state from both the left and right sides.
