Description

  The present invention relates to a locking device that locks a door of a game machine such as a pachinko machine or a pachislot machine in a closed position.

  In general, a game machine such as a pachislot machine includes a housing and a door. One side portions of the housing and the door are provided so as to be rotatable in the horizontal direction via a hinge. A locking device that locks the door in the closed position is provided between the other side portions of the housing and the door.

  As described in Patent Document 1 below, the locking device includes a pair of upper and lower flange members provided on the housing so as to be movable between a lock position and a release position, and a connection for connecting the pair of flange members. And a pair of upper and lower engaging members provided on the door. Each hook member is biased from the release position toward the lock position via a connecting hook by a biasing means such as a coil spring, and engages with each engagement member when the door rotates to the closed position. As a result, the locking device is locked, and the door is fixed in the closed position. On the other hand, when the lock provided on the door is opened, each hook member moves to the release position against the urging force of the urging means, and the engagement with the engagement member is released. As a result, the locking device is unlocked, and the door can be opened and rotated from the closed position.

  Moreover, the locking device has a locking member. One end of the locking member is rotatably provided on the connecting rod, and the locking portion is provided on the other end. In a state where the connecting rod and the flange member are positioned at the lock position, when the locking member rotates to the rotation prevention position, the locking portion is locked to the housing. As a result, the connecting rod and the flange member are fixed in the locked position, and the door is prevented from being opened illegally. On the other hand, when the locking member is positioned at the rotation allowable position, the locked state of the locking portion with respect to the housing is released. As a result, the connecting rod and the flange member can move from the lock position to the release position.

Japanese Patent No. 3127290

  In the above conventional locking device, the locking member is configured to rotate about one end thereof, so that if the locking portion is provided on one end side from the other end edge of the locking member, the locking portion The part on the other end side rotates more than necessary as the locking member rotates, and the occupied space of the locking member increases. Therefore, there is a problem that the locking portion has to be disposed at the other end edge of the locking member, and is largely restricted in design. In addition, the locking member not only rotates around one end, but also moves integrally with the connecting rod between the lock position and the release position, so that the occupied space of the locking member is further increased. There has been a problem of greatly affecting the arrangement of members.

In order to solve the above problem, the present invention is provided between a housing of a game machine and a door connected to the housing so as to be rotatable between a closed position and an open position in a substantially horizontal direction. A locking device for a game machine, comprising: a hook member and a locking member provided on the housing; and an engagement member provided on the door, wherein the hook member is engaged with the engagement member. It is possible to move between the locked position and the release position where the engagement with the engagement member is released, and the locking member prevents the hook member from moving from the predetermined position to the release position side. In a locking device for a game machine that is movable between a movement preventing position and a movement-permitting position that allows movement of the saddle member, the movement-preventing position and the locking device are maintained in a state in which the locking member maintains a certain posture. It is characterized in that it can move between the movement allowable positions.
In this case, it is desirable that the locking member can be moved linearly. In particular, the locking member is formed with a guide portion extending in parallel with the moving direction thereof, and the housing is engaged with the guide portion so that the locking member can move in the longitudinal direction thereof. It is desirable that an engagement guide part to be moved is provided. The guide portions are a pair of guide holes extending in parallel with the moving direction of the locking member, and the engagement guide portions are inserted into the pair of guide holes so as to be relatively movable in the longitudinal direction thereof. More preferably it is an axis.

  According to the present invention having the above-described characteristic configuration, since the locking member moves while maintaining a constant posture, the movement amount of each part of the locking member is the same, and there is no portion that moves more than necessary. In addition, the locking member is provided on the housing and does not move together with the flange member. Therefore, the space occupied by the locking member can be reduced as much as possible. Moreover, since the movement amount of the locking member is the same in each part, the location where the locking part is provided is not specified. Therefore, the design freedom of the locking member can be expanded.

The best mode for carrying out the present invention will be described below with reference to the drawings.
1 and 2 show a pachislot machine (game machine) 1 in which a locking device 4 according to a first embodiment of the present invention is used. The pachi-slot machine 1 includes a housing 2 having a substantially rectangular parallelepiped box shape with an open front portion, and a door 3 for opening and closing the front opening portion of the housing 2. One side portion (left side portion in FIG. 1) of the door 3 is connected to one side portion of the housing 2 via a slide hinge (not shown) so as to be rotatable in a substantially horizontal direction. The door 3 can be rotated between a closed position shown in FIG. 3 in which the back surface 3a substantially contacts the front surface 2a of the housing 2 and an open position separated from the closed position by about 90 ° to 110 °. .

  As shown in FIGS. 1 to 3, a locking device 4 according to the present invention is provided between the other side portions of the housing 2 and the door 3. The locking device 4 includes a housing side unit 5 provided on the other side inner surface 2 b of the housing 2 and a door side unit 6 provided on the other side inner surface 3 b of the door 3.

  As shown in FIGS. 1 to 5, the housing side unit 5 has a metal housing side mounting plate 11. The mounting plate 11 is disposed so that its longitudinal direction is substantially in the vertical direction and its width direction is in the front-rear direction of the housing 2, and is fixed along the front end of the inner surface 2 b of the other side portion of the housing 2. Has been. A notch is formed in the front end portion of the other side inner surface 2b of the housing 2 between the front end portion of the inner surface 2b of the other side of the housing 2 and the mounting plate 11, and thus along the mounting plate 11. A storage space S extending in the direction is provided. One side portion (lower side portion in FIG. 3) of the mounting plate 11 is projected from the front surface 2a of the housing 2 toward the door 3 side.

  As shown in FIGS. 1 to 3, 6 and 7, the door side unit 6 has a door side mounting plate 12. The mounting plate 12 is formed in a substantially “U” cross section by bending a metal plate. The mounting plate 12 is disposed with the longitudinal direction thereof substantially directed in the vertical direction and the opening portion facing the housing 2, and is fixed along the front end portion of the inner surface of the other side portion of the door 3. . As shown in FIG. 3, when the door 3 is rotated to the closed position, one side portion of the attachment plate 11 enters the attachment plate 12. This prevents a wire or the like from being inserted between the front surface 2a of the housing 2 and the back surface 3a of the door 3, and thus prevents the door 3 from being opened and turned illegally.

  As shown in FIGS. 4 and 5, the housing side unit 5 includes an upper collar member (a collar member) 13 and a lower collar member (a collar member) 14. Each of the upper collar member 13 and the lower collar member 14 is made of a metal plate material, and is arranged so as to be movable in the same direction with the longitudinal direction thereof directed in the same direction as the longitudinal direction of the mounting plate 12. . Most of the upper side of the upper collar member 13 is accommodated in the accommodation space S so as to be movable in the longitudinal direction (vertical direction). A lower end portion of the upper collar member 13 is projected from a notch portion 11 a formed in the mounting plate 11 to one side portion side of the housing 2, and the front surface of the mounting plate 11 (one side portion side of the housing 2 is arranged). (Facing surface). Most of the lower side of the lower collar member 14 is accommodated in the accommodation space S so as to be movable in the vertical direction. An upper end portion of the lower collar member 14 is projected from a notch portion 11b formed in the mounting plate 11 to one side portion side of the housing 2, and a lower end portion of the upper collar member 13 and a horizontal direction of the housing 2 ( The left and right directions in FIG.

  A guide hole 13 a extending in the vertical direction is formed at the lower end of the upper collar member 13. A guide shaft (engagement guide portion) 15 fixed to the mounting plate 11 is inserted into the guide hole 13a so as to be movable in the vertical direction. When the guide shaft 15 abuts against the upper and lower ends of the guide hole 13a, the movable range of the upper collar member 13 in the vertical direction is limited.

  The guide shaft 15 is provided with a central portion of the connecting member 16 so as to be rotatable. One end portion of the connecting member 16 is connected to the lower end portion of the upper collar member 13 via a shaft 17 so as to be movable in the front-rear direction (left-right direction in FIG. 5) of the casing 2 and not movable in the vertical direction. The other end of the connecting member 16 is connected to the upper end of the lower collar member 14 via a shaft 18 so as to be movable in the front-rear direction of the housing 2 and not movable in the vertical direction. Therefore, the upper and lower flange members 13 and 14 are simultaneously moved by the same distance in the opposite directions in the vertical direction.

  An upper hook portion 13 b is formed on the upper end portion of one side portion of the upper collar member 13. The upper hook portion 13 b protrudes outward from the accommodation space S toward the door 3 through a notch portion 11 c formed at the upper end portion of the mounting plate 11. An upper engagement recess 13c is formed on the upper end surface of the upper hook portion 13b. A lower hook portion 14 b is formed at the lower end portion of one side portion of the lower collar member 14. The lower hook portion 14 b protrudes outward from the accommodation space S toward the door 3 through a notch portion 11 d formed at the lower end portion of the mounting plate 11. A lower engagement recess 14c is formed on the lower end surface of the lower hook portion 14b.

  As shown in FIGS. 6 and 7, an upper engagement roller (engagement member) 19 is rotatably provided on the upper end portion of the door-side mounting plate 12 via a shaft 20. The upper engagement roller 19 is disposed so as to be fitted into the upper engagement recess 13c when the upper collar member 13 is moved upward from the downward movement limit position in a state where the door 3 is positioned at the closed position. . When the upper collar member 13 moves to a position slightly before the upper limit position, the upper engagement roller 19 hits the lower end of the upper engagement recess 13c. The position of the upper collar member 13 at this time is the lock position. When the upper collar member 13 moves downward from the lock position to a position slightly before the lower movement limit position, the upper engagement roller 19 escapes relatively upward from the upper engagement recess 13c. At this time, the position of the upper collar member 13 is the release position.

  A lower engagement roller (engagement member) 21 is rotatably provided on the lower end portion of the door-side mounting plate 12 via a shaft 22. The lower engagement roller 21 is disposed so as to fit into the lower engagement recess 14c when the lower collar member 14 is moved downward from the upper movement limit position with the door 3 being in the closed position. Yes. The relationship between the lower engagement roller 21 and the lower engagement recess 14c is the same as the relationship between the upper engagement roller 19 and the upper engagement recess 13c except that the upper and lower sides are reversed. Therefore, the description of the relationship between the lower engagement roller 21 and the lower engagement recess 14c is omitted.

  The outer diameters of the upper and lower engagement rollers 19 and 21 are set to be substantially the same as the groove widths of the upper and lower engagement recesses 13c and 14c. Therefore, when the upper and lower flange members 13 and 14 are moved to the lock position and the engagement rollers 19 and 21 are respectively fitted in the engagement recesses 13c and 14c, the door 3 is maintained in the closed position with little play.

  A coil spring 25 serving as an urging means is provided between the housing side mounting plate 11 and the lower collar member 14. The lower spring member 14 is always urged downward by the coil spring 25. As a result, the upper collar member 13 is constantly biased upward via the lower collar member 14 and the connecting member 16. Therefore, when the door 3 is in the closed position, it is in the locked position unless the cylinder lock 24 to be described below is opened, except when the lower rod member 14 and the upper rod member 13 are broken or illegally operated. positioned.

  As shown in FIG.6 and FIG.7, the support plate 23 is provided in the intermediate part in the up-down direction of the door side attachment plate 12 so that position adjustment is possible. The support plate 23 is provided with a cylinder lock 24 as a lock that can be operated from the outside of the housing 2 and the door 3 when the door 3 is closed. When the cylinder lock 24 is opened from a neutral position to an open position by a key (not shown), the lower collar member 14 moves upward from the lock position to the release position against the urging force of the coil spring 25. Of course, the upper collar member 13 moves downward from the lock position to the release position in conjunction with the upward movement of the lower collar member 14. When the key can be freely rotated in the open position, the upper and lower flange members 13 and 14 are moved to the locked position by the biasing force of the coil spring 25, and the key is returned to the neutral position.

  The structure for moving the upper and lower flange members 13 and 14 to the release position side by the cylinder lock 24 will be described. As shown in FIGS. 6 and 7, the cylinder shaft 24a of the cylinder lock 24 has a substantially "<" character. An operation plate 26 having a shape is fixed. When the cylinder lock 24 is opened, the operation plate 26 rotates counterclockwise in FIG.

  An opening operation member 27, a reset member 28, and an unlocking member 29 are coupled to the support plate 23 by a shaft 30 so as to be movable in a predetermined range in the vertical direction. The opening movement member 27 is movable in a predetermined range up and down with respect to the shaft 30. On the other hand, the reset member 28 and the locking release member 29 are connected to each other by a shaft 30 so as not to move. Therefore, the reset member 28 and the locking release member 29 move integrally in the vertical direction with respect to the support plate 23 and the opening operation member 27. The locking release member 29 can be rotated around the shaft 30.

  A coil spring 31 as an urging means is provided between the opening operation member 27 and the reset member 28. The opening member 27 is urged downward by the coil spring 31, while the reset member 28 is urged upward. When the cylinder lock 24 is located at the neutral position, the opening limit member 27 is restricted by the shaft 30, the long hole 23 a formed in the support plate 23, and the long hole 27 a formed in the opening action member 27. The reset member 28 and the locking release member 29 are positioned at the upper limit position regulated by the shaft 30 and the long hole 23a.

  Now, it is assumed that the door 3 is located at the closed position and the upper and lower flange members 13 and 14 are located at the lock position. In this state, when the cylinder lock 24 is opened and the operation plate 26 is rotated counterclockwise in FIG. 7, the lower end portion of the operation plate 26 is engaged with the opening operation member 27, which is connected to the coil spring 31. Move upward against the urging force. Then, the protrusion 27 b of the opening operation member 27 hits the lower collar member 14 and moves it upward against the urging force of the coil spring 25. When the cylinder lock 24 is opened to the open position, the lower collar member 14 moves to the release position. Of course, in conjunction with the movement of the lower collar member 14 to the release position, the upper collar member 13 moves downward from the lock position to the release position, and the upper and lower engagement rollers 19, 21 escape from the upper and lower engagement recesses 13c, 14c. To do. As a result, the door 3 can be opened and rotated from the closed position.

  When the door 3 is opened and rotated by a predetermined angle or more from the closed position, this is detected by a sensor (not shown) provided in the housing 2. Based on the detection signal, the game of the game machine 1 is interrupted. When restarting the interrupted game, after the door 3 is rotated to the closed position, the key is inserted into the cylinder lock 24 and the reset operation is performed from the neutral position to the reset position (rotation in the direction opposite to that during the opening operation). Operation). When the cylinder lock 24 is reset, the operation plate 26 rotates clockwise in FIG. 7 and moves the reset member 28 downward. Then, the reset piece 28a of the reset member 28 switches the reset switch 32 (see FIGS. 8 to 12 and FIGS. 18 to 20) provided on the support plate 23 to the ON state. This resumes the game.

  When the door 3 is rotated from the open position to the closed position, the upper and lower flange members 13 and 14 are automatically moved from the lock position to the release position, and then moved again to the lock position, as will be described later. It is done. Accordingly, the upper and lower flange members 13 and 14 are engaged with the engagement rollers 19 and 21 without hitting the upper and lower engagement rollers 19 and 21, respectively.

  However, there is a case where an accident occurs in which the upper and lower flange members 13 and 14 stop between the release position and the lock position even though the door 3 is rotated to the closed position. If the game is resumed in such a state, the hook members 13 and 14 and the engagement rollers 19 and 21 are not correctly engaged, so that the door 3 may be opened and the game machine 1 may be cheated. In order to prevent such a problem, in this locking device, the reset member 28 is formed with a protruding portion 28b. When the lower lock member 14 is positioned between the release position and the lock position when the cylinder lock 24 is reset while the door 3 is in the closed position, the protrusion 28b Move to the locked position. Therefore, when the reset is completed, the flange members 13 and 14 and the engagement rollers 19 and 21 can be reliably engaged. In other words, unless the flange members 13 and 14 and the engagement rollers 19 and 21 are correctly engaged, the reset member 28 cannot move downward, and the reset switch 32 cannot be turned on. . Therefore, the game is not resumed in a state where the flange members 13 and 14 are not engaged with the engagement rollers 19 and 21. Therefore, it is possible to reliably prevent fraud.

  Further, in this locking device, in order to prevent the upper and lower flange members 13 and 14 from being illegally moved from the lock position to the release position, thereby preventing the door 3 from being illegally opened from the closed position, FIG. As shown in FIG. 5, a locking member 33 is used. As shown in FIG. 5B, the locking member 33 is formed with a pair of guide holes 33 a and 33 a that are inclined downward toward the back side of the housing 2. The guide shaft 15 is inserted into the lower guide hole 33a so as to be relatively movable in the longitudinal direction of the guide hole 33a. A shaft (engagement guide portion) 34 fixed to the housing side mounting plate 11 is inserted into the upper guide hole 33a so as to be relatively movable in the longitudinal direction of the guide hole 33a. Thereby, the locking member 33 can move linearly only in the longitudinal direction of the guide hole 33a with respect to the mounting plate 11. Moreover, the locking member 33 moves in a state in which the posture is constant. The locking member 33 is biased obliquely upward along the longitudinal direction of the guide hole 33a by a coil spring 35 as a biasing means provided between the locking member 33 and the housing side mounting plate 11. The shafts 15 and 34 are abutted against the lower ends of the respective guide holes 33a. Thereby, the upward movement of the locking member 33 is prevented. The position of the locking member 33 at this time is a movement preventing position.

  A shaft 36 serving as a locking portion is fixed to the locking member 33. As shown in FIGS. 13 and 14, the shaft 36 is movably inserted into a hole 14 d formed in the lower collar member 14. A lower inner surface of the hole 14d is a horizontal locking surface 14e. When the shafts 15 and 34 are in contact with the lower end portions of the respective guide holes 33a, that is, when the locking member 33 is positioned at the movement preventing position, the locking surface 14e is illegally moved upward from the locked position. When the heel member 14 is moved, the lower collar member 14 is disposed so as to abut against the shaft 36 before reaching the release position. When the locking surface 14e hits the shaft 36, the lower collar member 14 cannot move further to the release position side. This prevents the upper and lower flange members 13 and 14 from being illegally moved from the lock position to the release position, and consequently the engagement between the flange members 13 and 14 and the engagement rollers 19 and 21 is illegally released. It is prevented.

  When the engagement between the collar members 13, 14 and the engagement rollers 19, 21 is normally released by the cylinder lock 24, the locking member 33 obstructs the movement of the lower collar member 14 toward the release position. Don't be. For this purpose, not only does the shaft 36 not hit the locking surface 14e, but the shaft 36 moves downward relative to the lower rod member 14 as the lower rod member 14 moves to the release position side. Need to be able to move on.

  Therefore, the lower collar member 14 is formed with a long hole 14f extending vertically. The upper end portion of the long hole 14f is open to the lower end portion on the back side of the hole 14d. In addition, the long hole 14f has the locking member 33 against the urging force of the coil spring 35 until the position immediately before the upper limit position where the shafts 15 and 34 abut against the upper end portions of the respective guide holes 33a (movement allowable position). When moving obliquely downward, the shaft 36 is disposed so as to face the upper end opening of the long hole 14f. The width of the long hole 14f is set to be substantially the same as the outer diameter of the shaft 36, and the shaft 36 can enter the long hole 14f from its upper end open portion (communication portion with the hole 14d). Therefore, when the lower collar member 14 moves upward in a state where the locking member 33 has moved to the movement allowable position, the shaft 36 enters the elongated hole 14f. Therefore, the lower collar member 14 can move to the release position.

  In order to move the locking member 33 to the movement allowable position in accordance with the opening operation of the cylinder lock 24, the door-side unit 6 is provided with the locking release member 29 described above. That is, when the cylinder lock 24 is opened in the state in which the door 3 is in the closed position, the upper and lower flange members 13 and 14 are in the locked position, and the locking member 33 is in the movement preventing position, The lock release member 29 is rotated about the shaft 30 in the clockwise direction in FIG. 7 (counterclockwise in FIG. 5) by the operation plate 26 and abuts against the lock member 33. Then, the locking release member 29 moves the locking member 33 obliquely downward along the guide hole 33a as the cylinder lock 24 is opened. When the cylinder lock 24 is opened to a predetermined intermediate position between the neutral position and the open position, the locking member 33 is moved to the movement allowable position. The movement of the locking member 33 to the movement allowable position is performed before the shaft 36 hits the locking surface 14e, that is, before the lower collar member 14 is prevented from moving to the release position side by the locking member 33. The Thereafter, the locking member 33 is maintained at the movement allowable position regardless of the opening operation up to the opening position of the cylinder lock 24. On the other hand, when the cylinder lock 24 is opened from the intermediate position to the open position, the lower collar member 14 moves to the release position. Of course, at this time, the shaft 36 enters the elongated hole 14f.

  Regardless of the opening operation from the intermediate position of the cylinder lock 24, the locking member 33 can be maintained at the movement allowable position by adopting, for example, one of the following two mechanisms. The first mechanism forms a cam surface at a location where the locking release member 29 abuts against the locking member 33. The cam surface moves the locking member 33 from the movement preventing position to the movement allowable position in response to the opening operation of the cylinder lock 24 from the neutral position to the intermediate position. However, while the cylinder lock 24 is opened from the intermediate position to the open position, the locking member 33 is not moved and is maintained at the movement allowable position. In the case of this mechanism, the locking release member 29 is always rotated by the operation plate 26 during the opening / closing operation between the neutral position and the open position of the cylinder lock 24. In the second mechanism, while the cylinder lock 24 is opened from the neutral position to the intermediate position, the operation plate 26 rotates the locking release member 29, thereby allowing the locking member 33 to move from the movement preventing position. However, when the cylinder lock 24 is opened to the open position beyond the intermediate position, the operation plate 26 does not rotate the locking release member 29 and maintains the fixed rotation position. Is. In this case, when the cylinder lock is closed from the open position to the neutral position, the lock release member 29 is returned to the original initial position by the lock member 33.

  When the upper and lower flange members 13 and 14 are in the release position, when the key of the cylinder lock 24 is released so that it can be freely rotated, the opening operation member 27 is moved to the lower limit position by the coil spring 31. It is done. Further, the upper and lower flange members 13 and 14 are returned from the release position to the lock position by the coil spring 25. When the eaves members 13 and 14 move to the lock position, the shaft 36 moves to the upper end of the long hole 14f and enters the hole 14d. As a result, the locking member 33 can be moved obliquely upward along the elongated hole 33 a and is moved to the movement blocking position by the coil spring 35.

  As shown in FIGS. 4 and 5, a receiving member 37 is fixed to the housing side mounting plate 11. The receiving member 37 has a horizontal support portion 37 a extending in the front-rear direction of the housing 2. On the other hand, a support roller 38 is rotatably provided on the support plate 23 of the door-side mounting plate 12 as shown in FIGS. The support roller 38 is disposed such that its lower surface is located on the same horizontal plane as the upper surface of the support portion 37a. Moreover, the support roller 38 is disposed so as to ride on the support portion 37a when the door 3 is located between the closed position and a position that is a predetermined distance away from the closed position. Therefore, when the door 3 is rotated to the closed position, as shown in FIG. 12, the support roller 38 rides on the support portion 37 a, and the other side portion of the door 3 is the housing via the support roller 38 and the receiving member 37. 2 supported by the other side. Thereby, drooping of the other side part of the door 3 is prevented.

  The support roller 38 not only prevents the other end portion of the door 3 from sagging, but also moves the upper and lower flange members 13 and 14 from the lock position to the release position when the door 3 is rotated from the open position side to the closed position. In addition to being used as an operation member for movement, the door 3 is also used as a member constituting an unauthorized operation prevention mechanism for preventing the door 3 from being opened and turned illegally from the closed position.

  That is, as shown in FIGS. 4, 5, 13, and 14, the upper end portion of the locking member 33 has an inclined plate portion 33 b that is inclined upward from the near side to the far side of the housing 2, And the horizontal part 33c extended horizontally toward the back | inner side of the housing | casing 2 from the upper end part of this inclination board part 33b is provided. As shown in FIGS. 8 and 9, the inclined plate portion 33 b is configured such that the support roller 38 is positioned at the movement preventing position when the door 3 is closed and rotated to a position before the closed position by a predetermined distance. It arrange | positions so that it may abut against the intermediate part of the inclination board part 33b of the stop member 33. FIG. When the door 3 further closes and pivots in a state where the support roller 38 is in contact with the inclined plate portion 33b, the support roller 38 pushes the locking member 33 through the inclined plate portion 33b, along the longitudinal direction of the long hole 33a. Move back diagonally downward. When the support roller 38 reaches the end on the back side of the inclined plate portion 33b, that is, the intersection of the inclined plate portion 33b and the horizontal portion 33c, the locking member 33 has moved to the movement allowable position, and the support roller 38 Is placed on the horizontal portion 33c beyond the intersecting portion, the locking portion 33 is maintained at the movement allowable position. Therefore, when the support roller 38 is on the horizontal portion 33c, the shaft 36 can enter the elongated hole 14f. When the support roller 38 is on the horizontal portion 33c, the horizontal portion 33c is not only located on the same horizontal plane as the support portion 37a, but is also in contact with the front end portion of the support portion 37a in the front-rear direction of the housing 2. Is located. Therefore, when the door 3 is further turned and closed, the support roller 38 smoothly moves from the horizontal portion 33c onto the support portion 37a.

  At the upper end of the lower collar member 14, an inclined plate portion 14 g that forms a downward gradient from the near side to the far side of the housing 2 is formed. As shown in FIG. 10, when the support roller 38 is transferred from the inclined plate portion 33b to the horizontal portion 33c, the inclined plate portion 14g of the lower collar member 14 in which the support roller 38 is located at the lock position is almost at the same time. It arrange | positions so that it may contact | abut on the lower surface of the inclination board part 14g. When the door 3 is closed and rotated in a state where the support roller 38 is in contact with the inclined plate portion 14g, the lower collar member 14 is pushed upward toward the release position by the support roller 38. At this time, since the locking member 33 is positioned at the movement allowable position, when the shaft 36 enters the elongated hole 14f, the lower collar member 14 can move to the release position side. When the door 3 is closed and rotated until the support roller 38 reaches the tip of the inclined plate portion 14g (the end on the back side of the housing 2), the upper and lower flange members 13 and 14 reach the release position, and the upper hook portion 13b. And the lower hook part 14b face the upper and lower engaging rollers 19, 21 respectively. When the door 3 is further closed and rotated, the support roller 38 is separated from the inclined plate portion 14g to the back side of the housing 2. At substantially the same time, the support roller 38 moves from the horizontal portion 33c to the support portion 37a.

  When the support roller 38 is separated from the inclined plate portion 14 g toward the back side of the housing 2, the upper and lower flange members 13 and 14 are moved toward the lock position by the coil spring 25. However, when the upper and lower flange members 13 and 14 move toward the lock position, the upper and lower hook portions 13b and 14b immediately abut against the upper and lower engagement rollers 19 and 21, respectively. Therefore, the upper and lower flange members 13 and 14 hardly move.

  When the support roller 38 is transferred from the horizontal portion 33c onto the support portion 37a, the support roller 38 does not prevent the locking member 33 from moving upward. However, at this time, as shown in FIG. 14, since the shaft 36 enters the long hole 14f, the locking member 33 can move only in the vertical direction. On the other hand, the locking member 33 is only allowed to move in an oblique direction by the shafts 15 and 34 and the long hole 33a. Therefore, even if the support roller 38 moves from the horizontal portion 33c to the support portion 37a, the locking member 33 does not move to the movement preventing position side, and is maintained at the movement allowable position by the lower collar member 14.

  When the door 3 is further closed and rotated, the engagement rollers 19 and 21 roll on the hook portions 13b and 14b. When the door 3 reaches the closed position, the engagement rollers 19 and 21 face the engagement recesses 13c and 14c, respectively. Then, the upper and lower flange members 13 and 14 are moved to the lock position side by the coil spring 25, and the engagement rollers 19 and 21 enter the engagement recesses 13c and 14c. Then, the upper and lower flange members 13 and 14 move to the lock position, and the engagement rollers 19 and 21 enter the engagement recesses 13c and 14c until they hit the bottom portions thereof. Thereby, the door 3 is maintained in the closed position.

  When the upper and lower flange members 13, 14 move to the lock position, the shaft 36 escapes from the long hole 14f and enters the hole 14d. As a result, the locking member 33 can move in an oblique direction, and is moved obliquely upward along the longitudinal direction of the long hole 33 a by the coil spring 35. The locking member 33 moves to the movement preventing position and stops.

  The support roller 38 cooperates with the inclined plate portion 14g to prevent the door 3 from being illegally opened and rotated. For example, when the shafts 20 and 22 that respectively support the engagement rollers 19 and 21 are cut, the engagement between the engagement rollers 19 and 21 and the hook portions 13b and 14b does not function. The door 3 can be opened and rotated from the closed position without moving the 13, 14 from the lock position to the release position. However, in this locking device 4, as shown in FIG. 15, when the upper and lower flange members 13, 14 are in the locked position, the door 3 is at a predetermined angle from the closed position (for example, 2, 3). When it is opened and rotated by about (°), the outer peripheral surface of the support roller 38 abuts against the abutting portion 14h formed at the back end of the inclined plate portion 14g. As a result, the support roller 38 is prevented from moving to the front side of the housing 2, and as a result, the opening rotation of the door 3 is prevented. Therefore, the door 3 is not illegally opened and turned.

  The support roller 38 may abut against the upper surface of the inclined plate portion 14g without abutting against the abutting portion 14h. When the support roller 38 hits the upper surface of the inclined plate portion 14g, the support roller 38 tries to move the lower collar member 14 downward. At this time, the lower collar member 14 is located at the lock position and cannot move downward. Accordingly, when the support roller 38 abuts against the upper surface of the inclined plate portion 14g, the support roller 38 can no longer move to the front side of the housing 2, and the door 3 is prevented from being illegally opened.

  When the door 3 is normally rotated from the closed position, the upper and lower flange members 13 and 14 are moved by the cylinder lock 24 from the locked position to the released position before the door 3 is opened and rotated. Yes. As shown in FIG. 17, when the lower collar member 14 is located at the release position, the entire inclined plate portion 14 g including the abutting portion 14 h is located above the support roller 38. Therefore, when the door 3 is normally opened and rotated, the support roller 38 does not hit the abutting portion 14h.

  The opening / closing operation | movement of the door 3 of the pachislot machine 1 provided with the locking device 4 of the said structure is demonstrated collectively. Now, it is assumed that the door 3 is in the open position. At this time, the eaves members 13 and 14 are located at the lock position, and the locking member 33 is located at the movement prevention position. When the door 3 is turned from the open position through the position shown in FIG. 8 to a position closer to the front by a predetermined distance from the closed position, the support roller 38 has the inclined plate portion 33b of the locking member 33 as shown in FIG. I hit it. Thereafter, when the door 3 is further closed and rotated toward the closed position, the support roller 38 moves the locking member 33 to the movement allowable position shown in FIG. At substantially the same time, the support roller 38 comes into contact with the lower surface of the inclined plate portion 14g of the lower collar member 14. Accordingly, when the door 3 is further turned and closed, the support roller 38 moves the upper and lower flange members 13 and 14 from the lock position to the release position side as the door 3 is turned (see FIG. 11). Thereafter, when the door 3 is rotated to the closed position, the support roller 38 is separated from the inclined plate portion 14g to the back side of the housing 2, and as shown in FIG. 12, the upper and lower flange members 13 and 14 are coil springs. 25 to the lock position. Then, the engagement rollers 19 and 21 enter the engagement recesses 13c and 14c, respectively. Thereby, the door 3 is maintained in the closed position. After the upper and lower flange members 13 and 14 are moved to the lock position, the locking member 33 is moved to the movement prevention position by the coil spring 35. When the door 3 is in the closed position, the support roller 38 is supported by the receiving member 37. Thereby, drooping of the other side part of the door 3 is prevented. If the cylinder lock 24 is reset after the door 3 is turned to the closed position, the interrupted game is resumed.

  When opening the door 3 located at the closed position, the cylinder lock 24 is opened from the neutral position to the open position. Then, as shown in FIGS. 15 to 17, the locking member 33 is moved from the movement prevention position to the movement allowable position by the locking release member 29, and the upper and lower flange members 13, 14 are moved from the lock position to the release position. Moved. The door 3 can be opened by rotating the door 3 while maintaining that state. Here, the locking member 33 linearly moves diagonally in the vertical direction between the movement preventing position and the movement allowable position without rotating, and the entire locking member 33 moves by a certain distance. Therefore, there is no part that moves more than necessary as in the case of rotation. Therefore, the occupied space of the locking member 33 can be narrowed. Moreover, the locking member 33 is provided on the mounting plate 11 and does not move together with the upper and lower flange members 13 and 14. Therefore, the occupied space of the locking member 33 can be further reduced. In addition, since the locking member 33 has the same moving distance in any part, the installation position of the shaft 36 serving as the locking part can be changed as necessary. Therefore, the degree of design freedom can be improved.

  In addition, since the lower collar member 14 is provided on the housing 2 and the opening operation member 27 is provided on the door 3, when the door 3 is opened more than a predetermined angle from the closed position, the opening operation member 27 is lowered. Separated from the collar member 14. As a result, even if the cylinder lock 25 is maintained in the open position, the upper and lower flange members 13 and 14 can move from the release position to the lock position side. However, at this time, the engagement rollers 19 and 21 are opposed to the upper and lower surfaces positioned on the door 3 side from the engagement recesses 13c and 14c of the hook portions 13b and 14b, respectively. Therefore, even if the opening operation member 27 is separated from the lower collar member 14, the engagement rollers 19 and 21 do not enter the engagement recesses 13c and 14c again. When the door 3 is further opened and rotated, the engaging rollers 19 and 21 are separated from the hook portions 13b and 14b toward the door 3 side. Then, the upper and lower flange members 13 and 14 are moved to the lock position by the coil spring 25. Thereafter, the locking member 33 is moved to the movement preventing position by the coil spring 35. When the door 3 rotates from the closed position to a position where the engagement rollers 19 and 21 cannot enter the engagement recesses 13c and 14c, the game of the game machine 1 is interrupted.

  When the upper and lower flange members 13 and 14 are moved from the lock position to the release position without using the cylinder lock 24 in order to open the door 3 illegally while the door 3 is in the closed position. The abutment surface 14 e abuts against the shaft 36 fixed to the engagement member 33. As a result, the lower collar member 14 is prevented from moving from the lock position to the release position side beyond the predetermined position. Therefore, the state in which the engagement rollers 19 and 21 enter the engagement recesses 13c and 14c is maintained, and an unauthorized opening operation of the door 3 is prevented.

  Even if the engagement between the engagement rollers 19 and 21 and the upper and lower flange members 13 and 14 is released by some means, when the door 3 is opened from the closed position, the support roller 38 is brought into contact with the lower flange member 14. At 14h, the door 3 is prevented from further opening. As a result, the unauthorized opening operation of the door 3 is more reliably prevented.

  As described above, the support roller 38 is used not only as a component member of the drooping prevention mechanism of the door 3 but also as a component member of an unauthorized operation prevention mechanism that prevents the door 3 from being illegally opened. Therefore, the structural member corresponding to the support roller 38 of the unauthorized operation prevention mechanism of the door 3 can be omitted, thereby simplifying the structure of the locking device 4 and reducing the manufacturing cost thereof. In particular, in this locking device 4, the support roller 38 is also used as a moving means for moving the upper and lower flange members 13, 14 from the lock position to the release position, and further, the locking member 33 is moved from the movement prevention position to the movement allowable position. Therefore, the structure of the locking device 4 can be further simplified and the manufacturing cost can be further reduced.

  Moreover, in this locking device 4, the latch release member 29 is interposed between the locking member 33 and the operation plate 26 for moving this to the movement allowable position. In such a case, as compared with the case where the locking member 33 and the operation plate 26 are directly engaged, the degree of freedom of the installation position of the locking member 33 can be expanded, and the locking member 33 It can be placed at a position where it is difficult to operate illegally. Thereby, unauthorized opening operation of the door 3 can be prevented more reliably.

  21 and 22 show a second embodiment of the present invention in which a stopper is provided on the locking member 33. FIG. In this embodiment, the horizontal portion 33 c of the locking member 33 extends from the inclined plate portion 14 g of the lower collar member 14 to the back side of the housing 2, and the support roller 38 is accompanied by the closing rotation of the door 3. After passing through the inclined plate part 14g of the lower collar member 14, the horizontal part 33c of the locking member 33 is passed. When the door 3 is in the closed position, the support roller 38 gets on the support portion 37 a of the receiving member 37. When the door 3 is opened and rotated by a predetermined angle (for example, 2 to 3 °) from the closed position, the support roller 38 comes into contact with the end surface of the horizontal portion 33c. Thereby, the opening rotation of the door is prevented. In this case, since the horizontal portion 33c is also used as a stopper, the movement preventing position and the movement allowable position of the locking member 33 are the first and second positions of the stopper, respectively, and the coil spring 35 is attached to the second portion. It will also be used as a force means.

  In this embodiment, since the horizontal portion 33c is used as a stopper, the inclined plate portion 14g of the lower collar member 14 moves the lower collar member 14 from the lock position to the release position by striking the support roller 38. It is used only as an engaged portion for this purpose, and does not hit the support roller 38 when the door 3 is turned.

  23 to 25 show a third embodiment of the present invention. In this embodiment, an unauthorized opening operation of the door 3 can be prevented more reliably. As described above, when the door 3 is opened from the closed position, the locking member 33 is moved from the movement preventing position to the movement allowable position. Therefore, if the locking member 33 is not illegally moved to the movement allowable position, the possibility that the door 3 is illegally opened can be reduced accordingly. Therefore, in this embodiment, the receiving member 37 is formed with a shielding portion 37b. The shielding portion 37 b extends downward from the rear end portion of the support portion 37 a, and is disposed behind the locking member 33 so as to face the locking member 33 in the front-rear direction of the housing 2. Therefore, the locking member 33 has a smaller exposed area to the rear by the amount facing (covered) the shielding portion 37b, and the locking member 33 can be illegally operated from the rear side of the housing 2. Can be lowered. Further, the support plate 23 is formed with a shielding portion 23b. The shielding portion 23 b is disposed on the left side of the locking member 33 (one side of the housing 2) so as to face the locking member 33 in the left-right direction of the housing 2. Therefore, the possibility that the locking member 33 is illegally operated from the rear side of the housing 2 can be reduced.

In addition, this invention is not limited to said embodiment, In the range which does not deviate from the summary, it can change suitably.
For example, in the above-described embodiment, the shaft 36 is fixed to the locking member 33, and the shaft 36 is engaged with and disengaged from the lower collar member 14. However, the locking member 33 has a protruding portion instead of the shaft 36. May be provided integrally.
In the above embodiment, the locking member 33 is linearly moved, but may be moved on a curve such as an arc as long as the locking member 33 is moved in a fixed state.
