(2) First Embodiment (2-1) Configuration of Banknote Storage Cassette FIGS. 7A and 7B show the above-described banknote storage cassette 20 for reject banknotes (FIG. 2) to which the present invention is applied. The banknote storage cassette 40 for reject banknotes by 1st Embodiment which is a specific example is shown. The banknote storage cassette 40 has a box-shaped housing (hereinafter also referred to as a cassette housing) 41.

  Incidentally, in the following description, the left direction indicated by the arrow a2 in the figure when the banknote storage cassette 40 is viewed facing the front surface 41A of the cassette housing 41 is also referred to as the cassette left direction, The opposite right direction is also called the cassette right direction.

  In the following description, the upward direction indicated by the arrow b2 in the figure when the banknote storage cassette 40 is viewed facing the front surface 2A of the cassette housing 41 is also referred to as the cassette upward direction. Is also referred to as the cassette downward direction.

  Further, in the following description, the front direction indicated by the arrow c2 in the figure when the banknote storage cassette 40 is viewed facing the front surface 2A of the cassette housing 41 is also referred to as the cassette front direction, and the cassette front direction. The direction on the back side opposite to the direction is also referred to as the cassette rear direction.

  In the following description, the front surface of the cassette housing 41 (that is, the cassette front surface in the cassette housing 41) 41A is also referred to as the cassette front surface 41A, and the back surface (that is, the cassette rear surface in the cassette housing 41). ) 41B is also referred to as a cassette back surface 41B.

  In the following description, the upper surface 41C of the cassette housing 41 (that is, the cassette upper surface in the cassette housing 41) is also referred to as the cassette upper surface 41C, and the lower surface (that is, the cassette lower surface in the cassette housing 41). 41D is also referred to as a cassette lower surface 41D.

  In the cassette front surface 41A of the cassette housing 41, for example, a strip-shaped front plate parallel to the cassette upward direction from the cassette lower surface 41D to the cassette upper surface 41C is left at the right end portion, and an opening 41AX is formed on the entire left side.

  A door 42 that opens and closes the opening 41AX on the cassette front surface 41A of the cassette housing 41 connects the left end of the door 42 and the left edge of the opening 41AX via a hinge (not shown). It is attached so that it can be opened and closed.

  The door 42 is provided with a lock portion 43 at the right end portion of the back surface 42A for locking the cassette housing 41 in a closed state.

  The door 42 is one of the components of the lock unit 43 at the right end of the surface 42B, and a lock 44 that is operated to lock the door 42 with respect to the cassette housing 41 and to release the lock. The key hole 44A is exposed and attached.

  Further, inside the cassette housing 41, for example, a reject banknote 45 conveyed from the banknote deposit / withdrawal unit on the upper back side, and a banknote inlet (not shown) formed on the upper side of the cassette back surface 41B are provided. A bill taking-in mechanism (not shown) made up of a motor, a roller and the like is provided for taking in the inside.

  Furthermore, in the cassette housing 41, a banknote mount 46 for placing the reject banknote 45 is arranged at the center, and a spring-like elasticity that biases the banknote mount 46 in the upward direction of the cassette. A body (not shown) is also provided.

  Therefore, in the state where the reject banknote 45 is not housed in the cassette housing 41, the banknote mounting base 46 is positioned as close as possible to the banknote taking-in mechanism by urging the cassette upward by the elastic body.

  Each time the reject banknote 45 is conveyed from the banknote deposit / withdrawal unit, the cassette housing 41 takes the reject banknote 45 into the inside via the banknote inlet and the banknote intake mechanism, and sequentially enters the banknote mount 46. While being stacked, the bill mounting base 46 is lowered by the thickness of the reject bill 45 by the weight of the reject bill 45.

  Thereby, the cassette housing | casing 41 is making the loading condition of the reject banknote 45 with respect to the banknote mounting base 46 always equal, and has piled up the several reject banknote 45 on the banknote mounting base 46 as much as possible.

  Thus, the banknote storage cassette 40 stores the reject banknote 45 conveyed from the banknote deposit / withdrawal unit inside the cassette housing 41.

  When the bill storage cassette 40 is detached from the bill storage unit, the reject bill 45 can be taken out (collected) from the inside by opening the door 42 with respect to the cassette housing 41.

(2-2) Configuration of Lock Unit Next, the configuration of the lock unit 43 will be described with reference to FIGS. 8A and 8B and FIGS. 9A and 9B.

  8A and 9A show the inner surface of the front plate of the cassette housing 41 with the door 42 closed with respect to the cassette housing 41 (that is, the back surface of the cassette front surface 41A described above). ) It is a figure which shows the structure of the said lock part 43 at the time of seeing the lock part 43 with 41E and back surface 42A of the door 42. FIG.

  8B and 9B show the case where the lock part 43 is looked up from the bottom together with the front plate of the cassette casing 41 and the door 42 with the door 42 closed with respect to the cassette casing 41. It is a figure which shows the structure of the said lock part.

  The lock part 43 has the lock 44 as described above. The lock 44 is a cylinder lock and is formed in a cylindrical shape.

  Then, the lock 44 is inserted into a circular through-hole drilled in the surface 42B of the door 42 so that one end protrudes from the surface 42B of the door 42 and the other end protrudes from the back surface 42A of the door 42. The door 42 is attached.

  The one end face of the lock 44 is provided with the above-described key hole 44A for inserting the key 50 along the center axis of the lock 44 (hereinafter also referred to as the lock center axis).

  Then, the lock 44 rotates the key 50 inserted into the keyhole 44A in one rotation direction within a first angle range such as 90 degrees, for example, around the lock central axis together with the drilled portion of the keyhole 44A on one end face (this In this case, for example, it has a predetermined internal structure that is rotated in the clockwise direction) and in the other rotation direction opposite to this (in this case, for example, counterclockwise direction).

  Further, in the other end portion of the lock 44, the key 50 inserted into the keyhole 44A is interlocked with the rotation in one rotation direction and the other rotation direction, and is smaller than 90 degrees around the lock center axis, for example, 5 degrees. A rotation mechanism (not shown) that rotates in one rotation direction and the other rotation direction in a second angle range such as 10 degrees is provided.

  The rotation mechanism of the lock 44 aligns the central axis of the prismatic arm rotation shaft 51 with the lock center axis, holds one end of the arm rotation shaft 51, and fixes the other end to the other of the lock 44. It protrudes from the center of the end face.

  As a result, the lock 44 is interlocked with the key 50 inserted into the keyhole 44A when the key 50 is rotated in one rotation direction (that is, when the key 50 rotates in one rotation direction within the first angle range). Thus, the arm rotation shaft 51 is fully rotated in one rotation direction within the second angle range about the lock center axis.

  When the key 50 inserted into the keyhole 44A is rotated in the other rotation direction (that is, when the key 50 is fully rotated in the other rotation direction in the first angle range), the lock 44 is interlocked with this. The arm rotation shaft 51 is fully rotated in the other rotation direction within the second angle range around the lock center axis.

  Incidentally, in the following description, the rotation operation in one rotation direction with respect to the key 50 inserted into the key hole 44A is an operation of rotating the key 50 inserted into the key hole 44A in one rotation direction in the first angle range. That is.

  In the following description, the rotation operation in the other rotation direction with respect to the key 50 inserted into the key hole 44A is an operation of fully rotating the key 50 inserted into the key hole 44A in the other rotation direction within the first angle range. That is.

  Furthermore, the lock 44 is attached to the other end portion via an arm rotation shaft 51 with an L-shaped rotation arm 52 with one surface of the rotation arm 52 facing the back surface 42A of the door 42. .

  In this case, for example, the turning arm 52 has a semicircular tip 52B having a radius shorter than the width of the base 52A on one end side of the strip-shaped base 52A having a width shorter than the diameter of the lock 44. Are provided to form an L-shape. Further, the rotating arm 52 is formed with a square through hole on the other end side of the root portion 52A.

  Then, the turning arm 52 is directed from the one side so that the tip 52B is directed to the left of the cassette and the root 52A is parallel to the cassette upward direction when the arm turning shaft 51 is fully rotated in the other rotation direction. The other end of the arm rotation shaft 51 is inserted into the through hole.

  Accordingly, when the key 50 inserted into the keyhole 44A is rotated in the other rotation direction, the lock 44 rotates the rotation arm 52 together with the arm rotation shaft 51 in the other rotation direction, so that the rotation arm 52 The base 52A is parallel to the cassette upward direction, and the tip 52B is positioned almost directly below the lock 44.

  Further, when the key 50 inserted into the keyhole 44 </ b> A is rotated in one rotation direction, the lock 44 rotates the rotation arm 52 in one rotation direction together with the arm rotation shaft 51. The portion 52A is made parallel to the diagonally lower left direction, and the tip 52B is displaced to the left from directly below the lock 44.

  Incidentally, the lock unit 43 includes a lock lever 53 for locking the door 42 with respect to the cassette housing 41 and a lever support unit 54 for supporting the lock lever 53 on the back surface 42 </ b> A of the door 42.

  The lock lever 53 has a body portion 53A made of, for example, a substantially H-shaped flat plate. Further, on one surface of the trunk portion 53A, a plate-like arm abutting portion 53B is located along the one side surface (that is, the trunk longitudinal direction) on one side of the wide portion 53AX on one end side in the longitudinal direction of the trunk portion 53A. Projecting parallel to the direction).

  In the following description, the longitudinal direction of the body part 53A in the lock lever 53 is also referred to as the body longitudinal direction, and the wide part 53AX on one end side in the body longitudinal direction in the body part 53A is also referred to as one end wide part 53AX.

  Further, an L-shaped arm portion 53C is provided on the one end side wide portion 53AX of the body portion 53A near the other side surface of the end surface.

  In this case, the arm portion 53C has a substantially right triangular tip 53CY on one end side of the strip-shaped root portion 53CX, the other end side of the root portion 53CX as a bottom surface perpendicular to the longitudinal direction of the root portion 53CX, and It is provided so as to form an L shape with one end side of the root portion 53CX as an inclined surface.

  In the arm portion 53C, the other end side of the base portion 53CX is joined to the end face of the one end side wide portion 53AX, and one end side of the base portion 53CX is protruded to the upper side of one surface of the body portion 53A.

  Further, the arm portion 53C has the bottom surface of the distal end portion 53CY flush with one surface of the body portion 53A, and the entire distal end portion 53CY protrudes above one surface of the body portion 53A and in front of the other side surface of the one end side wide portion 53AX. ing.

  Further, the trunk portion 53A has a narrow center of gravity between the one end side wide portion 53AX and the other end side wide portion 53AY in the center of the trunk portion 53A, for example, the center of gravity of the entire lock lever 53. The overall thickness and the shape and size of the wide portion 53AY on the other end side are appropriately selected so as to be positioned inside the constricted portion 53AZ.

  Incidentally, in the following description, the center of gravity of the lock lever 53 is also called a lever center of gravity, and the wide portion 53AY on the other end side in the body longitudinal direction in the body portion 53A is also called the other end side wide portion 53AY.

  Further, on one surface of the body portion 53A, a circular through hole 53D having a predetermined radius centering on an axis line passing through the position of the lever center of gravity and perpendicular to the one surface (hereinafter also referred to as a center of gravity position axis line) is formed in the constricted portion 53AZ. It has been drilled.

  On the other hand, the lever support portion 54 has a cylindrical lever rotation shaft, and is formed by providing a disk-shaped lever holding portion at the other end of the lever rotation shaft.

  In this case, the lever support portion 54 is selected such that the length of the lever rotation shaft is slightly longer than the thickness of the body portion 53 </ b> A of the lock lever 53, and the diameter of the lever rotation shaft is the through hole of the lock lever 53. It is selected to be approximately equal to the diameter of 53D.

  Further, the lever support portion 54 is selected such that the diameter of the lever holding portion is larger than the diameter of the through hole 53D of the lock lever 53.

  The lock lever 53 has one end side wide portion 53AX interposed between the back surface 42A of the door 42 and the tip end portion 52B of the rotating arm 52 with the other surface of the body portion 53A facing the back surface 42A of the door 42. Further, the constricted portion 53AZ and the other end side wide portion 53AY are arranged to be positioned below the tip end portion 52B of the rotating arm 52.

  In this state, in the lever support portion 54, the lever rotation shaft is inserted into the through hole 53D of the lock lever 53 from one surface side of the body portion 53A, and one end of the lever rotation shaft is joined to the back surface 42A of the door 42. ing.

  Thereby, the lever support part 54 makes the axial centerline of the lever rotation shaft inserted in the through-hole 53D of the lock lever 53 coincide with the gravity center position axis passing through the position of the lever gravity center.

  Then, the lever support portion 54 has the lock lever 53 on the back surface 42A of the door 42 and the other direction of rotation around the lever rotation axis while the other surface of the body portion 53A is parallel to the back surface 42A of the door 42. It is supported so as to be rotatable in the rotation direction.

  By the way, the lever rotation shaft of the lever support portion 54 is passed through the coil portion of the torsion spring 55 between the back surface 42 </ b> A of the door 42 and the lock lever 53.

  The torsion spring 55 has one end extending from the coil portion, for example, one end engaging protrusion (not shown) provided on the other side of the body 53A of the lock lever 53 and below one side of the one end wide portion 53AX. Is engaged.

  The other end of the torsion spring 55 that is provided with a predetermined torque and whose other end extends from the coil portion is provided obliquely below and to the right of the constricted portion 53AZ of the lock lever 53 on the back surface 42A of the door 42. The engagement protrusion 56 is engaged.

  Accordingly, the torsion spring 55 biases the lock lever 53 to rotate in one rotation direction.

  Further, on the rear surface 42A of the door 42, a columnar rotation restricting portion for restricting the rotation of the lock lever 53 in one rotation direction at a predetermined position facing the other side surface of the one end wide portion 53AX of the lock lever 53. 57 has been planted.

  Therefore, when the key 50 inserted into the keyhole 44A is rotated in the other rotation direction and the rotation arm 52 is rotated in the other rotation direction in conjunction with this, the lock unit 43 is rotated. The front end 52B is displaced leftward of the cassette.

  Thus, at this time, the lock portion 43 rotates the lock lever 53 in one rotation direction for locking the door 42 with respect to the cassette housing 41 by the urging of the torsion spring 55.

  When the base portion 52A of the rotation arm 52 is parallel to the cassette upper direction, the lock portion 43 abuts the other side surface of the one end side wide portion 53AX of the lock lever 53 against the rotation restricting portion 57, and the body longitudinal direction For example, the planting position of the rotation restricting portion 57 with respect to the back surface 42A of the door 42 and the joining position of the lever rotation shaft of the lever support portion 54 are selected as appropriate so that is parallel to the cassette upper direction.

  Incidentally, in the following description, when the lock lever 53 is rotated in one rotation direction, the other side surface of the one end side wide portion 53AX of the lock lever 53 that is abutted against the rotation restricting portion 57 is referred to as the rotation restricting portion abutting surface. Call.

  Further, when the lock restricting portion 43 abuts the rotation restricting portion abutting surface of the lock lever 53 against the rotation restricting portion 57 in this way, the distal end portion 53CY of the arm portion 53C of the lock lever 53 is placed in front of the right end surface of the door 42. The length of the distal end portion 53CY of the arm portion 53C is appropriately selected so as to project.

  Furthermore, when the lock portion 43 abuts the rotation restricting portion abutment surface of the lock lever 53 against the rotation restricting portion 57, the lock abutment surface of the arm abutment portion 53 </ b> B slightly contacts the end portion 52 </ b> B of the rotating arm 52. The width of the one end side wide portion 53AX, the thickness of the arm abutting portion 53B, the protruding position, and the like are appropriately selected so as to be separated from each other.

  On the other hand, when the key 50 inserted into the keyhole 44A is rotated in one rotation direction and the rotation arm 52 is rotated in one rotation in conjunction with this, the lock portion 43 is rotated. The front end 52B of 52 is abutted against the arm abutting surface of the lock lever 53 and is displaced rightward as it is.

  Thereby, the lock part 43 rotates the lock lever 53 in the other rotation direction for releasing the lock | rock of the door 42 with respect to the cassette housing | casing 41 in this case.

  When the base portion 52A of the rotating arm 52 is parallel to the diagonally downward left direction, the lock portion 43 pulls the tip end portion 53CY of the arm portion 53C of the lock lever 53 into the back surface 42A of the door 42, for example, The length of the root portion 52A of the rotating arm 52 is appropriately selected so as to be positioned above the rotation restricting portion 57.

  Further, on the inner surface 41E of the front plate of the cassette housing 41, for example, a rectangular plate-like lock plate 58 projects one end portion in the short direction of the lock plate 58 into the opening 41AX, and The central portion of the end surface is arranged to face the rotation restricting portion abutting surface of the one end side wide portion 53AX of the lock lever 53.

  As a result, the lock unit 43 (FIGS. 8A and 8B) rotates the key 50 inserted into the key hole 44A in the other rotation direction with the door 42 closed with respect to the cassette housing 41. Then, the lock lever 53 is rotated in one rotation direction by the urging of the torsion spring 55 in accordance with the rotation of the rotating arm 52 in conjunction with the rotation arm 52, and the rotation restricting portion abutting surface is pushed into the rotation restricting portion 57. Hit it.

  That is, at this time, the lock portion 43 rotates the lock lever 53 in one rotation direction by the urging of the torsion spring 55, but the abutment surface of the rotation restriction portion abuts against the rotation restriction portion 57, and The rotation in the rotation direction is restricted so as not to rotate further in one rotation direction.

  In the state where the rotation of the lock lever 53 in one rotation direction is thus restricted, the lock portion 43 positions the tip end portion 53CY of the arm portion 53C of the lock lever 53 closer to one end on the one surface of the lock plate 58. Let

  As a result, the lock portion 43 moves the door 42 against the cassette housing 41 so that one end portion of the lock plate 58 is sandwiched between the back surface 42A of the door 42 and the distal end portion 53CY of the arm portion 53C of the lock lever 53. It can be locked in the closed state.

  Incidentally, in the following description, the cassette is obtained by causing the rotation restricting portion abutment surface of the lock lever 53 to abut against the rotation restricting portion 57 and projecting the front end portion 53CY of the arm portion 53C in front of the right end surface of the door 42. The posture of the lock lever 53 that can be locked in a state where the door 42 is closed with respect to the housing 41 is also referred to as a lock posture.

  On the other hand, in the lock part 43 (FIGS. 9A and 9B), the key 50 inserted into the key hole 44A is rotated in one rotation direction while the door 42 is locked to the cassette housing 41. Then, in conjunction with this, the lock lever 53 is rotated in the other rotation direction according to the rotation of the rotation arm 52 in one rotation direction.

  That is, the lock unit 43 rotates the lock lever 53 whose body longitudinal direction is parallel to the cassette upper direction to a predetermined rotation angle in the other rotation direction by rotating the rotation arm 52 in one rotation direction.

  As a result, the lock portion 43 can retreat the tip end portion 53CY of the arm portion 53C of the lock lever 53 from one surface of the lock plate 58 to release the lock of the door 42 with respect to the cassette housing 41, and thus the cassette housing. The door 42 can be opened and closed with respect to 41.

  Incidentally, in the following description, the cassette housing 41 is configured such that the lock lever 53 is rotated in the other rotation direction to a predetermined rotation angle so that the distal end portion 53CY of the arm portion 53C is retracted from one surface of the lock plate 58. The posture of the lock lever 53 for releasing the lock of the door 42 is also referred to as a release posture.

  By the way, when the lock part 43 is operated to rotate the key 50 inserted into the key hole 44A in the other rotation direction even with the door 42 opened with respect to the cassette housing 41, the lock lever 53 is rotated once. It can be turned to the locked position.

  In addition, when the lock lever 53 is locked, the lock portion 43 is configured to prevent the lock lever 53 from rotating from the lock position to the other rotation direction other than urging the lock lever 53 to rotate in one rotation direction by the torsion spring 55. No mechanism is provided.

  Therefore, when the lock part 43 is pushed so that the door 42 is closed with respect to the cassette housing 41 after the lock lever 53 is brought into the locking posture while the door 42 is opened with respect to the cassette housing 41, one end of the lock plate 58. The inclined surface of the tip 53CY is brought into contact with the front edge of the surface at the arm 53C of the lock lever 53 and is slid.

  As a result, the lock portion 43 rotates the lock lever 53 from the locked posture once in the other rotation direction to cause the tip portion 53CY of the arm portion 53C to cross the one end surface of the lock plate 58, and then attach it by the torsion spring 55. The tip 53CY of the arm portion 53C is rotated around one end on one surface of the lock plate 58 by rotating in one rotation direction so as to return to the lock posture according to the force.

  In this way, the lock unit 43 automatically closes the door 42 with respect to the cassette housing 41 even if the door 42 is pushed against the cassette housing 41 while the lock lever 53 is in the locked posture. Can be locked.

  And although the lock part 43 is not provided with the mechanism which restricts the rotation to the other rotation direction of the lock lever 53 in this way, the lever gravity center is located inside the lock lever 53 by the lever support part 54 as mentioned above. The lever is supported so as to be rotatable in one rotation direction and the other rotation direction around the lever rotation axis.

  That is, the lock part 43 has the lever center of gravity of the lock lever 53 positioned on the axis center line of the lever rotation shaft of the lever support part 54, and supports the lock lever 53 so as to be rotatable at the position of the lever center of gravity. .

  Therefore, even when the lock unit 43 is accidentally dropped while the door 42 is locked to the cassette housing 41 when carrying the bill storage cassette 40 or attaching / detaching the bill storage unit to / from the bill storage unit, The applied impact force at the time of drop (that is, the force in the drop direction caused by the drop impact) can be received by the lever center of gravity located inside the lever rotation shaft of the lever support portion 54.

  Further, when the banknote storage cassette 40 is dropped, the lock unit 43 has a repulsive force generated by bouncing or rolling accompanying the falling of the banknote storage cassette 40 (that is, a force in the bounce direction applied to the banknote storage cassette 40 by bouncing. ) And centrifugal force on the lock lever 53 can also be received by the lever center of gravity located inside the lever rotation shaft of the lever support portion 54.

  Thus, when the banknote storage cassette 40 is dropped while the door 42 is locked to the cassette housing 41, the lock unit 43 avoids applying an external force to the lock lever 53 to rotate in the other rotation direction. Thus, the lock posture of the lock lever 53 can be maintained.

(2-3) Operation and Effect of First Embodiment In the above configuration, in the banknote storage cassette 40, the lock portion 43 is provided on the back surface 42A of the door 42 attached to the cassette housing 41 so as to be opened and closed. The lever rotation shaft of the lever support portion 54 is inserted into a through hole 53D formed at the position of the lever center of gravity of the lock lever 53 in the lock portion 43, and the lock lever 53 is attached to the back surface 42A of the door 42 by the lever support portion 54. Is supported so as to be rotatable about a lever rotation axis.

  That is, in the banknote storage cassette 40, the lever gravity center of the lock lever 53 is positioned on the axis center line of the lever rotation shaft of the lever support portion 54, and the lock lever 53 is rotatably supported at the position of the lever gravity center.

  The banknote storage cassette 40 is biased by the torsion spring 55 when the key 50 inserted into the key hole 44A of the lock 44 is rotated in the other rotation direction with the door 42 closed with respect to the cassette housing 41. As a result, the lock lever 53 is rotated in one rotation direction about the lever rotation axis to be in the locked posture, thereby locking the cassette housing 41 in the closed state of the door 42.

  In addition, when the bill storage cassette 40 is locked in the door 42 with respect to the cassette housing 41 and the key 50 inserted into the key hole 44A of the lock 44 is rotated in one rotation direction, the bill storage cassette 40 is interlocked with this. The lock arm 53 that rotates in one rotation direction rotates the lock lever 53 in the other rotation direction around the lever rotation axis to the release posture, thereby unlocking the door 42 with respect to the cassette housing 41.

  Therefore, even when the bill storage cassette 40 is accidentally dropped with the door 42 locked with respect to the cassette housing 41 when carrying or attaching / detaching to the bill storage unit, the bill storage cassette 40 is in a state of being dropped on the lock lever 53. The impact force can be received by the lever center of gravity located inside the lever rotation shaft of the lever support portion 54.

  Further, when the bill storage cassette 40 is dropped, the repulsive force and centrifugal force generated by the bounce and rolling of the bill storage cassette 40 due to the drop and applied to the lock lever 53 are also caused by the lever rotation shaft of the lever support portion 54. Can be received at the center of gravity of the lever located inside.

  Therefore, even if the bill storage cassette 40 is dropped while the door 42 is locked with respect to the cassette housing 41, the bill lever cassette 40 is applied to the lock lever 53 by the impact force at the time of dropping, the repulsive force or the centrifugal force caused by the dropping. The lock posture of the lock lever 53 can be maintained by avoiding the application of an external force that rotates in the other rotation direction.

  According to the above configuration, the bill storage cassette 40 supports the lock lever 53 on the back surface 42 </ b> A of the door 42 by the lever support portion 54 so that the lock lever 53 is rotatable about the lever rotation axis. When the key 50 inserted into the key hole 44A of the lock 44 is rotated in the other rotation direction with the door 42 closed, the lock lever 53 is moved around the lever rotation axis by the urging force of the torsion spring 55. When the door 42 is locked with respect to the cassette housing 41 by rotating in one rotation direction, the lever rotation shaft of the lever support portion 54 is inserted into the through hole 53D formed at the position of the lever center of gravity of the lock lever 53. I tried to do it.

  As a result, when the bill storage cassette 40 is dropped or applied to the lock lever 53 even if it is accidentally dropped with the door 42 locked to the cassette housing 41 during carrying or attachment / detachment to the bill storage unit, etc. And the repulsive force and centrifugal force generated by the bounce and rolling of the banknote storage cassette 40 due to the drop are received by the lever center of gravity located inside the lever rotation shaft for rotating the lock lever 53, It is possible to avoid applying an external force that rotates the lock lever 53 in the other rotation direction, and as a result, it is possible to maintain the lock posture of the lock lever 53 (that is, the door 42 is locked).

  Therefore, even if the bill storage cassette 40 is accidentally dropped with the door 42 locked with respect to the cassette housing 41 during carrying, attachment / detachment to the bill storage unit, etc., the impact, bounce, and rolling of the fall Thus, the door 42 can be kept closed with respect to the cassette housing 41 without opening alone.

  Further, for example, if the bill storage cassette 40 has a rattling that slightly moves in a direction orthogonal to the lock center axis on the rotation mechanism provided on the lock 44, a drop impact force is applied to the lock 44 when dropped. When the repulsive force or centrifugal force generated by the bounce or rolling of the bill storage cassette 40 due to the drop is applied to the lock 44, the rotation mechanism moves slightly in the lock 44 in the direction perpendicular to the lock center axis. There is a case.

  For this reason, the banknote storage cassette 40 rotates the lock lever 53 in the other rotation direction in consideration of the rattling of the rotation mechanism of the lock 44 when the lock lever 53 is in the locked position in the lock unit 43. For this purpose, the tip 52B of the pivot arm 52 is separated from the arm abutment surface of the lock lever 52.

  Therefore, the banknote storage cassette 40 is accidentally dropped in the state where the door 42 is locked to the cassette housing 41 when being carried or attached to or detached from the banknote storage unit, and the impact force or repulsive force due to the drop is applied to the lock 44. Even when the centrifugal force is applied and the rotation arm 52 moves together with the rotation mechanism, it is possible to avoid the tip 52B of the rotation arm 52 from being abutted against the arm abutting surface of the lock lever 53.

  That is, the banknote storage cassette 40 maintains the locked posture without rotating the lock lever 53 in the other rotation direction even if the turning arm 52 moves due to falling, and the door 42 opens with respect to the cassette housing 41 alone. Can remain closed without any problems.

(3) Second embodiment (3-1) Configuration of bill storage cassette FIGS. 10 (A) and 10 (B) are shown with the same reference numerals given to the corresponding parts to those in FIGS. 7 (A) and 7 (B). The banknote storage cassette 70 for reject banknotes by 2nd Embodiment which is a specific example of the banknote storage cassette 20 for reject banknotes (FIG. 2) to which this invention is applied is shown.

  The banknote storage cassette 70 is configured in the same manner as the banknote storage cassette 40 according to the first embodiment described above except for a partial configuration of the lock unit 71. Therefore, the configuration of the lock unit 71 will be described below.

(3-2) Configuration of Locking Section FIGS. 11A and 11B, in which the same reference numerals are assigned to the corresponding parts to FIGS. 8A and 8B and FIGS. 9A and 9B. FIGS. 12A and 12B show a lock portion 71 provided in the banknote storage cassette 70 according to the second embodiment.

  11A and 12A, as in FIGS. 8A and 9A, the cassette housing 41 is properly connected with the door 42 closed. It is a figure which shows the structure of the said lock part 71 at the time of seeing the lock part 71 with the inner surface 41E of a face plate, and the back surface 42A of the door 42. FIG.

  11B and 12B, as in FIGS. 8B and 9B, the cassette housing 41 is properly connected to the cassette housing 41 with the door 42 closed. It is a figure which shows the structure of the said lock part 71 at the time of looking up the lock part 71 from the bottom with a face plate and the door 42. FIG.

  In this case, in the lock portion 71, the lock lever 72 has a body portion 72A made of, for example, a substantially H-shaped flat plate.

  The body portion 72A has one end side wide portion formed on one end side in the body longitudinal direction in the same manner as the one end side wide portion 53AX of the lock lever 53 (FIGS. 8 and 9) according to the first embodiment described above. Part 72AX.

  That is, in the body portion 72A, the one end side wide portion 72AX has the same size and shape as the one end side wide portion 53AX of the lock lever 53 according to the first embodiment described above, and is a flat arm on one side. The abutting portion 72B is projected along the one side surface.

  Further, in the body portion 72A, an L-shaped arm portion 72C is joined to the one end side wide portion 72AX, and the other end side of the strip-shaped root portion 72CX is joined to the end surface of the rotation regulating portion abutting surface, and is substantially a right triangle shape. The front end portion 72CY is provided so as to protrude in front of the rotation restricting portion abutting surface.

  Further, the body portion 72A is similar to the constricted portion 53AZ of the lock lever 53 according to the first embodiment described above between the one end side wide portion 72AX and the other end side wide portion 72AY on the other end side in the body longitudinal direction. A narrow constricted portion 72AZ having a size and a shape is provided.

  Then, in the constricted portion 72AZ of the body portion 72A, as in the constricted portion 53AZ of the lock lever 53 according to the first embodiment described above, the lever for inserting the lever rotation shaft of the lever support portion 54 into the center portion. A through hole 72D having a diameter substantially equal to the diameter of the rotating shaft is formed.

  However, in the trunk portion 72A, the other end side wide portion 72AY is formed in a different shape and smaller in size than the other end side wide portion 53AY of the lock lever 53 according to the first embodiment described above. .

  That is, the other end side wide portion 72AY is lighter than the other end side wide portion 53AY of the lock lever 53 according to the first embodiment described above. Is formed.

  Therefore, the lock lever 72 has a weight on one end side in the body longitudinal direction (that is, one end side wide portion 72AX) rather than a weight on the other end side in the body longitudinal direction (that is, the weight of the other end side wide portion 72AY). The combined weight of the arm abutting portion 72B and the arm portion 72C is heavy.

  As a result, the lock lever 72 exists at a position different from the position of the lever center of gravity of the lock lever 53 according to the first embodiment described above, such as the inside of the center of the one end side wide portion 72AX near the center of the lever. doing.

  For this reason, on one surface of the body portion 72A, on the basis of a virtual line L1 extending from the position of the center of gravity of the lever inside the one end side wide portion 72AX to the other end side wide portion 72AY through the center of the through hole 72D, A rectangular long hole 72E is formed at a predetermined position of the wide end portion 72AY so that the longitudinal direction thereof is parallel to the virtual line L1, and the virtual line L1 passes through the center of the width of the long hole 72E.

  Further, the other end side wide portion 72AY of the trunk portion 72A has a center of gravity for adjusting the lever center of gravity to be positioned on the hole center line of the through hole 72D by adjusting the balance of the weight of the entire lock lever 72. The position adjustment unit 73 is attached through the long hole 72E.

  In this case, the center-of-gravity position adjustment unit 73 is formed by combining a weight 74 and an ultra-low head type male screw 75. The male screw 75 is formed in a disc shape with a head having a diameter longer than the width of the long hole 72E.

  The male screw 75 is selected such that the outer shape of the threaded portion is substantially equal to the width of the long hole 72E, and the length of the threaded portion is selected to be longer than the thickness of the body portion 72A.

  On the other hand, the weight 74 is formed in a cylindrical shape having a diameter longer than the width of the long hole 72E. In addition, a circular hole having a predetermined depth is formed on one surface of the weight 74 at a predetermined position closer to the peripheral surface than the center, and a thread corresponding to the screw portion of the male screw 75 is formed on the inner wall of the hole. That is, an internal thread is formed.

  The center-of-gravity position adjustment unit 73 protrudes from one surface of the body portion 72A at the threaded portion of the male screw 75 inserted into the long hole 72E of the wide end portion 72AY on the other end side from the other surface side of the body portion 72A of the lock lever 72. The portion is formed so as to be screwed into the female screw of the weight 74.

  That is, the center-of-gravity position adjustment unit 73 makes the screw center line of the male screw 75 parallel to the thickness direction of the body portion 72A and orthogonal to the imaginary line L1 with respect to the elongated hole 72E of the wide end portion 72AY on the other end side of the lock lever 72. Attached.

  Here, the center-of-gravity position adjusting unit 73 is appropriately selected for adjusting the position of the lever center of gravity in accordance with the position of the long hole 72E drilled to attach the center-of-gravity position adjusting unit 73 to the other-end-side wide portion 72AY. It has a predetermined weight.

  The center of gravity position adjusting unit 73 has a center of gravity of the center of gravity position adjusting unit 73 itself, for example, located near the center inside the weight 74.

  Incidentally, the center of gravity of the center-of-gravity position adjusting unit 73 itself is the center of gravity of the weight 74 and the entire male screw 75 in a state where the threaded portion is screwed to the female screw in order to attach to the other end side wide portion 72AY of the lock lever 72. The center of gravity is also referred to as the adjustment unit center of gravity.

  The center-of-gravity position adjusting unit 73 separates the formation position of the hole (that is, the female screw) from the position of the center of gravity of the adjusting unit by a predetermined distance in the weight 74 (for example, the hole does not cover the position of the center of gravity of the adjusting unit). The formation position of the hole is appropriately selected.

  By the way, the center-of-gravity position adjusting unit 73 is attached to the other end side wide portion 72AY of the lock lever 72 so as to adjust the position of the lever center of gravity with respect to the lock lever 72 when the lock unit 71 is assembled.

  In actual assembly of the lock portion 71, the screw portion of the male screw 75 is inserted into the elongated hole 72E of the wide end portion 72AY on the other end side from the other surface side of the lock lever 72 and screwed into the female screw of the weight 74 on one surface side. Although the center of gravity position adjusting unit 73 is attached to the other end side wide portion 72AY, at this time, the tightening of the male screw 75 with respect to the female screw of the weight 74 is slightly loosened.

  Thereby, in the assembly of the lock portion 71, the center of gravity position adjusting portion 73 attached to the wide end portion 72AY on the other end side of the lock lever 72 is moved along the virtual line L1 (that is, the longitudinal direction of the long hole 72E). It is possible to move in the proximity direction approaching the line and the separation direction away from it.

  In assembling the lock portion 71, the center-of-gravity position adjustment portion 73 attached to the other-end-side wide portion 72AY of the lock lever 72 is made rotatable about a screw center line shifted from the position of the adjustment portion center of gravity.

  In this state, in assembling the lock portion 71, the center-of-gravity position adjustment portion 73 attached to the wide end portion 72AY on the other end side of the lock lever 72 is moved in the proximity direction or the separation direction along the virtual line L1, The attachment position of the gravity center position adjustment part 73 with respect to the other end side wide part 72AY is adjusted along the virtual line L1.

  Thereby, in the assembly of the lock part 71, the position of the lever center of gravity in the lock lever 72 is displaced to the hole center line side of the through hole 72D along the virtual line L1, and the lever center of gravity is placed on the hole center line of the through hole 72D. It adjusts so that it may be located, or it may be located in the vicinity of the hole center line of through-hole 72D.

  At this time, in the assembly of the lock part 71, if the lever center of gravity can be adjusted to be positioned on the hole center line of the through hole 72D only by adjusting the mounting position of the center of gravity position adjusting part 73 along the virtual line L1, The center screw position adjusting portion 73 is fixed to the wide end portion 72AY of the other end side of the lock lever 72 by tightening the male screw 75 with respect to the 74 female screws.

  On the other hand, in the assembly of the lock part 71, it is difficult to position the lever center of gravity on the hole center line of the through hole 72D only by adjusting the mounting position of the center of gravity position adjusting part 73 along the imaginary line L1. The part 73 is rotated to one or the other about the screw center line, and the attachment angle around the screw center line of the gravity center position adjusting part 73 with respect to the other end side wide part 72AY is adjusted.

  Thereby, in the assembly of the lock part 71, the position of the lever center of gravity in the lock lever 72 is displaced toward the hole center line side of the through hole 72D along the direction intersecting the virtual line L1, and the lever center of gravity is displaced from the through hole 72D. Make fine adjustments so that they are positioned on the hole center line.

  In assembling the lock portion 71, the male screw 75 is tightened with respect to the female screw of the weight 74, and the center-of-gravity position adjusting portion 73 is fixed to the wide end portion 72 </ b> AY on the other end side of the lock lever 72.

  Incidentally, in assembling the lock portion 71, it is difficult to position the lever gravity center on the hole center line of the through hole 72D even if the attachment angle of the gravity center position adjustment portion 73 is adjusted. The attachment position and attachment angle of the position adjustment unit 73 are finely adjusted alternately and appropriately so that the lever center of gravity is finally positioned on the hole center line of the through hole 72D.

  In the assembly of the lock portion 71, when the adjustment of the position of the lever center of gravity is completed, the male screw 75 is tightened to the female screw of the weight 74, and the center of gravity position adjusting portion 73 is fixed to the wide end portion 72AY of the lock lever 72. Let

  In this way, in assembling the lock portion 71, the total weight addition position of the center-of-gravity position adjustment portion 73 with respect to the wide end portion 72AY on the other end side of the lock lever 72 is appropriately adjusted to adjust the balance of the weight of the lock lever 72 as a whole. The lever center of gravity can be positioned on the hole center line of the through hole 72D.

  The lock lever 72 whose lever center of gravity has been adjusted in this way has the other surface of the body portion 72A opposed to the back surface 42A of the door 42, like the lock lever 53 according to the first embodiment described above. One end side wide portion 72AX is interposed between the back surface 42A of the door 42 and the tip end portion 52B of the rotating arm 52, and the constricted portion 72AZ and the other end side wide portion 72AY are more than the tip end portion 52B of the rotating arm 52. It arrange | positions so that it may be located below.

  In this state, in the lever support portion 54, the lever rotation shaft is inserted into the through hole 72D of the lock lever 72 from one surface side of the body portion 72A so that the shaft center line coincides with the hole center line. Is joined to the back surface 42 </ b> A of the door 42.

  As a result, the lever support portion 54 has the lock lever 72 on the back surface 42A of the door 42 and the center of gravity of the lever inside (ie, on the axis center line) with the other surface of the body portion 72A parallel to the back surface 42A of the door 42. Is supported so as to be rotatable in one rotation direction and in the other rotation direction around a lever rotation shaft where is located.

  Therefore, the lock unit 71 is a cassette housing according to the rotation operation of the key 50 inserted into the key hole 44A of the lock 44, similarly to the lock unit 43 (FIGS. 8 and 9) according to the first embodiment described above. The door 42 can be locked with respect to 41, and the lock can be released.

  Incidentally, in the lock part 71, when the lock lever 72 is in the locked posture, the tip end part 52 </ b> B of the rotating arm 52 is placed on the arm abutting surface of the lock lever 72, as in the lock part 43 according to the first embodiment described above. Separated from.

  The lock unit 71 also has the above-described first configuration when the lock lever 72 is in a locked posture while the door 42 is opened with respect to the cassette housing 41 and the door 42 is pushed against the cassette housing 41 to close. Similar to the lock unit 43 according to the first embodiment, the cassette 42 can be automatically locked by closing the door 42.

  Then, the lock unit 71 adjusts the position of the lever center of gravity of the lock lever 72 by the center of gravity position adjusting unit 73 and positions the lock lever 72 on the axis center line of the lever rotation shaft of the lever support unit 54. It is supported so that it can rotate in position.

  Therefore, when the banknote storage cassette 70 is dropped, the lock unit 71 applies the impact force applied to the lock lever 72 at the time of the lever rotation of the lever support unit 54 in the same manner as the lock unit 43 according to the first embodiment described above. It can be received by the lever center of gravity located inside the dynamic shaft.

  Further, when the banknote storage cassette 70 is dropped, the lock unit 71 also acts on the lock lever 72 due to the repulsive force and centrifugal force generated by the bounce and rolling accompanying the fall of the banknote storage cassette 70. The lever can be received at the center of gravity of the lever located inside the lever rotation shaft.

  Thus, when the banknote storage cassette 70 is dropped with the door 42 locked to the cassette housing 41, the lock unit 71 avoids applying an external force to the lock lever 72 to rotate in the other rotation direction. Thus, the lock posture of the lock lever 72 can be maintained.

(3-3) Operation and Effect of Second Embodiment In the above configuration, in the banknote storage cassette 70, the lock portion 71 is provided on the back surface 42A of the door 42 attached to the cassette housing 41 so as to be opened and closed. In the lock part 71, a center of gravity position adjusting part 73 for adjusting the position of the lever center of gravity is attached to the lock lever 72.

  In the bill storage cassette 70, the position of the lever center of gravity of the lock lever 72 is adjusted by the center of gravity position adjusting unit 73, and the lever center of the lever support unit 54 that rotatably supports the lock lever 72 is rotated. Position it on the axis line of the dynamic axis.

  In this state, the bill storage cassette 70 is biased by the torsion spring 55 when the door 42 is closed with respect to the cassette housing 41 and the key 50 inserted into the key hole 44A of the lock 44 is rotated in the other direction. As a result, the lock lever 72 is rotated around the lever rotation axis in one rotation direction to lock the cassette housing 41 in the closed state.

  In addition, when the bill storage cassette 70 is locked in the door 42 with respect to the cassette housing 41 and the key 50 inserted into the key hole 44A of the lock 44 is rotated in one rotation direction, the bill storage cassette 70 is interlocked with this. The lock lever 72 is rotated in the other rotation direction around the lever rotation axis by the rotation arm 52 that rotates in one rotation direction to unlock the door 42 with respect to the cassette housing 41.

  Therefore, even when the banknote storage cassette 70 is accidentally dropped with the door 42 locked with respect to the cassette housing 41 during carrying or attachment / detachment to / from the banknote storage unit, The impact force can be received by the lever center of gravity located inside the lever rotation shaft of the lever support portion 54.

  Further, when the banknote storage cassette 70 is dropped, the repulsive force and centrifugal force generated by the bounce and rolling of the banknote storage cassette 70 due to the drop and applied to the lock lever 72 are also affected by the lever rotation shaft of the lever support portion 54. Can be received at the center of gravity of the lever located inside.

  Therefore, even if the banknote storage cassette 70 is dropped while the door 42 is locked with respect to the cassette housing 41, the lock lever 72 is applied to the lock lever 72 by the impact force at the time of dropping, the repulsive force or centrifugal force generated by the dropping. The lock posture of the lock lever 72 can be maintained by avoiding the application of an external force that rotates in the other rotation direction.

  In the banknote storage cassette 70, the position of the center of gravity of the lock lever 72 is adjusted by the center of gravity position adjusting portion 73 as described above, thereby forming the lock lever 72 in accuracy (that is, the shape and size, and the through hole 72D being drilled). The center of gravity of the lever can be easily and accurately positioned on the axis center line of the lever rotation shaft of the lever support portion 54 that rotatably supports the lock lever 72 without being affected by the accuracy of the installation position.

  According to the above configuration, the bill storage cassette 50 supports the lock lever 72 on the back surface 42 </ b> A of the door 42 by the lever support portion 54 so as to be rotatable about the lever rotation axis, and to the cassette housing 41. When the key 50 inserted into the key hole 44A of the lock 44 is rotated in the other rotation direction with the door 42 closed, the lock lever 72 is moved around the lever rotation axis by the urging force of the torsion spring 55. In order to lock the door 42 with respect to the cassette housing 41 by rotating in one rotation direction, a gravity center position adjustment unit 73 is attached to the lock lever 72, and the lever gravity center of the lock lever 72 is adjusted by the gravity center position adjustment unit 73. Adjustment was made so as to be positioned on the axial center line of the lever rotation shaft inserted into the through hole 72D of the lock lever 72.

  Thereby, the banknote storage cassette 70 can obtain the same effect as that obtained by the first embodiment described above, and in addition to this, the lock lever 72 is not affected by the formation accuracy of the lock lever 72. The lever center of gravity can be easily and accurately positioned on the axis center line of the lever rotation shaft of the lever support portion 54 that rotatably supports the lock lever 72.

  Therefore, even if the banknote storage cassette 70 is accidentally dropped in the state where the door 42 is locked with respect to the cassette housing 41 when carrying or attaching / detaching to / from the banknote storage unit, the lock lever 72 moves in the other rotation direction. It is possible to more reliably avoid the application of an external force that causes rotation, maintain the lock posture of the lock lever 72, and reliably keep the door 42 closed with respect to the cassette housing 41.
