Description

  The present invention relates to a locking device provided between a case and a door of a game machine such as a pachislot machine or a pachinko machine.

  Generally, this type of locking device has a pair of eaves members disposed at both upper and lower ends of a door, as described in Patent Document 1 below. The pair of flange members can rotate between an engagement position and an engagement release position, and is biased from the engagement release position toward the engagement position by a spring. On the other hand, a pair of engaging members are provided on the housing of the game machine. The pair of engaging members engage with the pair of hook members, respectively, when the hook member rotates from the disengagement position to the engagement position when the door is in the closed position. This maintains the door in the closed position.

  A cylinder lock is provided on the door. When the cylinder lock is opened, the pair of hook members are rotated from the engagement position to the disengagement position by the operating piece of the cylinder lock, and the engagement between the hook member and the engagement member is released. Thereby, the door can be opened and rotated from the closed position.

  In the conventional locking device, a lock member is used. The lock member prevents the flange member from being illegally rotated from the engagement position to the engagement release position without using the cylinder lock. Thereby, it is possible to prevent the door from being opened illegally, and thus to prevent the game machine from being cheated.

  In the above conventional locking device, since one lock member is used as one fraud prevention means, a plurality of lock members are required when using a plurality of fraud prevention means. As a result, there is a problem that the structure of the locking device becomes complicated and the manufacturing cost increases.

In order to solve the above-described problem, the present invention provides an engagement member fixed to one of a housing of a game machine and a door provided to the housing so as to be capable of opening and closing, and the housing. A hook member provided on either one of the doors so as to be displaceable between an engagement position engaged with the engagement member and an engagement release position released from the engagement member. And a lock provided on the door having an operating piece, and the hook member is displaced from the engagement position to the disengagement position in conjunction with an opening displacement of the operation piece by an opening operation of the lock. In the locking device for a game machine, a lock position for preventing displacement of the saddle member from exceeding the predetermined position from the engagement position to the disengagement position side is provided on any one of the housing and the door. A lock that allows displacement of the flange member from the engagement position to the disengagement position. A locking member that is displaceable between the unlocking position and is displaceable from the locking position to the unlocking position by opening displacement of the operating piece, and the locking member is moved from the disengaging position to the engaging position. Biasing means for biasing toward the head, and a contact member provided on the other of the housing and the door, and the door is closed and rotated from a predetermined first position to a second position. Sometimes, the locking member is displaced from the locked position to the unlocked position by the contact member, and the contact member is separated from the lock member when the door is closed and rotated beyond a predetermined passing position. Accordingly, the lock member is allowed to turn to the lock position side, and the lock member is displaced from the unlock position to the lock position by the biasing means, When the door is pivoted open from the closed position to a predetermined third position, the contact member abuts against the lock member positioned at the lock position, thereby opening the door beyond the third position. It is characterized by being prevented from moving.
In this case, the lock member is provided on one of the housing and the door so as to be rotatable between the lock position and the unlock position, and the door is moved from the first position to the second position. When the contact member is turned to the closed position, the contact member is brought into contact with the lock member to be rotated from the lock position to the lock release position. It is desirable that the locking member is rotated from the unlocking position to the locking position by the biasing means when the member is separated from the locking member.
Two hook members are provided apart from each other in the vertical direction, and two engagement members are provided corresponding to the two hook members so that the two hook members are displaced in opposite directions. When the lock member is positioned and fixed to one of the two flange members, and the lock member is located at the lock position, the lock member is engaged from the engagement position of the other flange member. It is desirable to prevent displacement beyond a predetermined position toward the release position.
When the door is closed and rotated from the second position to the passing position, the contact member abuts against the lock member located at the unlocking position, so that the lock member is brought together with the one flange member. It is desirable to be displaced from the engagement position to the engagement release position.

  According to this invention having the above-described characteristic configuration, the lock member prevents the collar member from rotating beyond the predetermined position from the engagement position to the engagement release position. In addition, the lock member prevents the door from rotating when it abuts against the abutment member when the door rotates from the closed position. Since the lock member is also used as two fraud prevention means, the number of lock members can be reduced accordingly.

The best mode for carrying out the present invention will be described below with reference to the drawings.
1 to 15 show an embodiment of the present invention. In this embodiment, the present invention is applied to a pachislot machine (game machine) 1 shown in FIGS. 1 and 2, and the pachislot machine 1 has a housing 2 and a door 3. The housing | casing 2 is formed in the substantially square box shape by which the front surface was open | released. One side portion of the front surface portion of the housing 2 (left side portion in FIGS. 1 and 2) is connected to one side portion of the door 3 so as to be rotatable about an axis slightly inclined with respect to the vertical line. . The door 3 may be rotatably connected to the housing 2 around a vertical axis. A locking device 4 for a game machine according to the present invention is provided between the other side of the front surface of the housing 2 and the other side of the door 3.

  The locking device 4 is for engaging the door 3 with the closed position where the front opening of the housing 2 is closed. When the door 3 is rotated from the open position side to the closed position, the door 3 is moved to the housing 2. Automatically in the closed position. When the cylinder lock 67 is opened while the door 3 is in the closed position, the locked state of the door 3 with respect to the housing 2 is released, and the door 3 can be rotated from the closed position to the open position. On the other hand, the door 3 is prevented from being illegally opened and rotated without depending on the cylinder lock 67.

  Moreover, in this pachislot machine 1, the game is interrupted when the door 3 is opened and rotated from the closed position during the game. When the cylinder lock 67 of the locking device 1 is reset after the door 3 is turned to the closed position, the reset switch RS is turned on and the game is resumed. Such a configuration is the same as that of a conventional pachislot machine. However, in this locking device 4, if the door 3 is not securely locked in the closed position at the time of resetting, the cylinder lock 67 cannot be reset, and the game cannot be resumed.

  The detailed configuration of the locking device 4 having such a function will be described. The locking device 4 includes a housing side unit 5 and a door side unit 6. The housing side unit 5 is attached to the inner surface of the other side portion of the front surface side (door 3 side) of the housing 2. The door-side unit 6 is attached to the inner surface of the other side portion of the back side of the door 3 (housing 2 side).

  First, the housing side unit 5 will be described. The housing side unit 5 has a housing side mounting plate 51 as shown in FIGS. The mounting plate 51 is made of a metal plate, and is disposed with its longitudinal direction directed in the vertical direction, and is fixed along the front end portion (the end portion on the door 3 side) of the inner surface of the other side portion of the housing 2. Has been. As shown in FIG. 3, the outer side (door 3 side) side of the mounting plate 51 is bent stepwise, and the mounting plate 51 is formed by a recess 2 a formed on the inner surface of the other side of the housing 2. A storage space S having a rectangular cross section extending vertically is formed. An outer side portion of the mounting plate 51 protrudes forward from the front surface of the housing 2 by a predetermined distance.

  The housing unit 5 further includes an upper hook member (upper connecting member) 52 and a lower hook member (lower connecting member) 53. The upper flange member 52 is made of a metal plate that is long in the vertical direction, and is disposed along the mounting plate 51. Most of the upper side of the upper flange member 52 is accommodated in the accommodation space S. A guide hole 52 a extending vertically is formed at the upper end of the upper flange member 52. A guide shaft G1 fixed to the mounting plate 51 is inserted into the guide hole 52a so as to be relatively movable in the vertical direction. Thereby, the upper end part of the upper side collar member 52 is connected with the attachment plate 51 so that a vertical movement is possible. On the upper end portion of the upper flange member 52, a flange portion (ridge member) 52b is formed. The flange 52b is disposed on the outer (door 3 side) side of the upper flange 52 and protrudes from the accommodation space S toward the door 3 through a through hole 51a formed in the mounting plate 51. ing. An engagement recess 52c is formed on the upper surface of the flange portion 52b. The bottom of the engaging recess 52c is formed in a semicircular shape. A notch 51 e is formed on the outer side of the upper end of the mounting plate 51. The notch 51e is disposed so as to face a portion located on the back side (side away from the door 3) of the housing 2 in the semicircular bottom portion of the engagement recess 52c. It has almost the same shape and dimensions as the part. A lower end portion of the upper flange member 52 protrudes from the accommodation space S through a through hole 51b formed in the attachment plate 51, and is a front surface of the attachment plate 51 (a surface facing one side of the housing 2; FIG. 4). It extends downward along the surface facing left). A guide hole 52 d that extends vertically is formed at the lower end of the upper flange member 52. A guide shaft G2 fixed to the mounting plate 51 is inserted into the guide hole 52d so as to be relatively movable in the vertical direction. Thereby, the lower end part of the upper collar member 52 is connected to the mounting plate 51 so as to be movable in the vertical direction.

  The lower hook member 53 is made of a metal plate material that is long in the vertical direction, and most of the lower side thereof is housed in the housing space S. At the lower end portion of the lower heel member 53, a heel portion (ridge member) 53b is formed. The flange portion 53 b is disposed on the outer side portion of the lower flange member 53, and protrudes from the accommodation space S toward the door 3 through a through hole 51 c formed in the attachment plate 51. An engagement recess 53c is formed on the lower surface of the flange portion 53b. The engagement recess 53c is arranged and formed symmetrically with the engagement recess 52c. A notch 51 f is formed on the outer side of the lower end of the mounting plate 51. This notch 51f is arranged so as to face a portion located on the back side (side away from the door 3) of the casing 2 of the upper bottom portion forming the semicircular shape of the engaging recess 53c, Are substantially the same shape and dimensions. An upper end portion of the lower flange member 53 protrudes from the accommodation space S through a through hole 51 d formed in the attachment plate 51, and extends upward along the front surface of the attachment plate 51. A guide hole 53 a extending in the vertical direction is formed at the upper end of the lower flange member 53. A guide shaft G2 is inserted into the guide hole 53a so as to be relatively movable in the vertical direction. Thereby, the lower collar member 53 is connected to the mounting plate 51 so as to be movable in the vertical direction.

  The upper hook member 52 and the lower hook member 53 are connected such that when one moves upward, the other moves downward. That is, the center part of the swing member 54 is rotatably provided on the guide shaft G2. One end of the swing member 54 is connected to the lower end of the upper flange member 52 via a shaft J1 so as to be rotatable and relatively movable in the horizontal direction. The other end portion of the swing member 54 is connected to the upper end portion of the lower flange member 53 via the shaft J2 so as to be rotatable and relatively movable in the horizontal direction. Therefore, when one of the upper flange member 52 and the lower flange member 53 moves upward (downward), the other moves downward (upward) by the same distance as the other. The movement range of the upper and lower flange members 52 and 53 is such that the upper and lower flange portions 52c and 53c are moved in the vertical direction by the guide shaft G1 and the guide hole 52a or by the guide shaft G2 and the guide hole 52d or the guide hole 53a. The engagement position that is most widely separated from each other and the engagement release positions at which the upper and lower flange portions 52c and 53c are closest to each other in the vertical direction are regulated.

  A biasing means 55 is provided between the lower flange member 53 and the attachment member 51. The urging means 55 includes a coil spring and other springs, and urges the lower flange member 53 downward. Therefore, the biasing means 55 biases the upper hook member 52 upward via the lower hook member 53 and the swing member 54. The upper hook member 52 and the lower hook member 53 are normally positioned at the engagement position by the biasing force of the biasing means 55.

  A lock member 56 is rotatably connected to the lower end portion of the upper flange member 52 via a horizontal axis J3. The lock member 56 is urged to rotate clockwise in FIG. 5 by an urging means 57 comprising a coil spring or other spring provided between the lock member 56 and the upper flange member 52. The lock member 56 is formed with a contact plate portion 56a facing the door 3 side. When the front surface of the contact plate portion 56a facing the door 3 comes into contact with the upper flange member 52, the lock member 56 cannot be rotated further in the clockwise direction. Hereinafter, the rotation position of the lock member 56 at this time is referred to as a lock position. The locking member 56 is positioned at the locking position by the urging means 57 at normal times except when the door 3 is opened and closed.

  A protrusion 56 b is formed at the lower end of the lock member 56. When the lock member 56 located at the lock position moves downward by a predetermined distance from the engagement position toward the disengagement position side together with the upper flange member 52 (at this time, the lower protrusion 56b). The member 53 moves upward by a predetermined distance from the engagement position toward the engagement release position side), and abuts against a protrusion 53d formed on the upper end of the lower flange member 53. As a result, the upper and lower flange members 52 and 53 cannot move further to the disengagement position side. However, when the lock member 56 is positioned at a lock release position described later, the protruding portion 56b does not hit the protruding portion 53d, and the upper and lower hook members 52, 53 are in the engagement position and the engagement release position. Can move freely between.

  A support member 58 made of a metal plate material is fixed to the mounting plate 51. The support member 58 has a guide portion 58a and a support plate portion 58b. The guide part 58a is inclined so as to go upward as it goes from the front side (door 3 side) of the housing 2 to the back side. The support plate portion 58b extends horizontally from the guide portion 58a toward the back side of the housing 2.

  Next, the door-side unit 6 will be described. The door-side unit 6 has a door-side mounting plate 61 as shown in FIGS. 1 to 3 and FIGS. 7 to 9. The mounting plate 61 is made of a metal plate, and is formed in a “U” cross section by bending the left and right sides so as to face each other. The mounting plate 61 is fixed along the inner surface of the other side portion of the door 3 with its longitudinal direction directed in the vertical direction. In addition, the mounting plate 61 is arranged with the opening portion facing the housing 2 side, and when the door 3 rotates to the closed position, the side portion of the housing side mounting plate 51 that protrudes outward from the housing 2. Enters the inside of the door side mounting plate 61, and both side wall portions 61 a and 61 b of the mounting plate 61 face the side portions of the housing side mounting plate 51.

  An engagement roller (engagement member) 62A is rotatably provided on the upper end portion of the attachment plate 61 via a horizontal axis J4. An engagement roller (engagement member) is provided on the lower end portion of the attachment plate 61. 62B is rotatably provided through a horizontal axis J5. The engaging rollers 62A and 62B have a circular cross section, and have substantially the same radius of curvature as the bottoms of the engaging recesses 52c and 53c. When the upper and lower flange members 52 and 53 move from the disengagement position to the engagement position in a state where the door 3 is located at the closed position, the engagement rollers 62A and 62B engage with the engagement recesses 52b and 53b. When the upper and lower flange members 52, 53 move to the disengagement position from that state, they are arranged so as to escape from the engagement recesses 52b, 53b, respectively. The engagement rollers 62A and 62B enter the engagement recesses 52c and 53c, respectively, so that the door 3 hits the front surface of the housing 2 and is held at the closed position where the opening is closed. When the engaging rollers 62A and 62B are in contact with the bottoms of the engaging recesses 52c and 53c, the side portions of the engaging rollers 62A and 62B on the side of the housing 2 enter the notches 51e and 51f, respectively. As a result, the engagement rollers 62A and 62B can be brought closer to the housing 2, and as a result, the side portion of the housing-side mounting plate 51 can be made to enter the door-side mounting plate 61 more greatly.

  Of the side wall portions 61a and 61b of the mounting plate 61, the side wall portion 61b located on one side of the door 3 (left side in FIG. 3) is cut out at the center. A support plate portion 61 d that protrudes from the cutout portion toward one side of the door 3 is formed at the center portion of the bottom wall portion 61 c of the mounting plate 61. A position adjustment plate 63 is fixed to a surface of the support plate 61d facing the housing 2 so that the position adjustment plate 63 can be adjusted in the horizontal direction (left-right direction in FIG. 3) along the front surface of the door 3.

  The position adjustment plate 63 is formed by bending a metal plate material at a right angle. The base 63a is fixed to the support plate 61d so that the position can be adjusted in the left-right direction in FIG. And an upright plate portion 63b protruding to the side. A support roller R1 is rotatably provided at the upper end of the upright plate portion 63b. When the door 3 rotates from the open position side to a predetermined position slightly before the closed position, the support roller R1 comes into contact with the guide portion 58a of the support member 58 and begins to roll thereon. When the door 3 reaches the closed position, it passes over the guide portion 58a. When the door 3 reaches the closed position, the door 3 is on the support plate 58b. Thereby, the other side part of the door 3 is supported by the housing 2 at a predetermined position in the vertical direction.

  A contact roller (contact member) R2 is rotatably provided at an intermediate portion in the vertical direction of the upright plate portion 63b. As shown in FIG. 11, the contact roller R2 is configured such that the door 3 is closed when the upper and lower flange members 52 and 53 are located at the engagement positions and the lock member 56 is located at the lock position. It is arranged so as to abut against the front surface of the abutting plate portion 56a of the lock member 56 when it rotates and reaches a position (first position) in front of a predetermined distance of the closed position. When the door 3 further closes and pivots in a state where the contact roller R2 hits the contact plate portion 56a, the contact roller R2 pushes the contact plate portion 56a toward the back side of the housing 2. As a result, the lock member 56 is rotated counterclockwise in FIG. 5 against the urging force of the urging means 57. When the lower end portion of the contact plate portion 56a hits the upper flange member 52, the lock member 56 can no longer be rotated counterclockwise (see FIG. 12). Hereinafter, the rotation position of the lock member 56 at this time is referred to as a lock release position. The position of the door 3 when the lock member 56 is rotated to the unlock position is the second position. When the lock member 56 is located at the unlock position, the lower flange member 53 does not hit the lock member 56. Therefore, the upper and lower hook members 52 and 53 can freely move between the engagement position and the engagement release position.

  As shown in FIGS. 12 and 13, in the state where the lock member 56 is located at the unlock position, the contact plate portion 56 a corresponds to the rotation angle from the lock position of the lock member 56 to the unlock position. It inclines so that it may go upwards as it goes to the back | inner side of the housing | casing 2. As shown in FIG. Therefore, when the door 3 is further closed and rotated while the lock member 56 is located at the unlock position, the contact roller R2 pushes the contact plate portion 56a downward. As a result, the upper and lower flange members 52 and 53 are moved from the engagement position to the engagement release position side against the urging force of the urging means 55. When the door 3 reaches a predetermined position (passing position) immediately before the closed position, as shown in FIG. 13, the lowermost portion of the contact roller R2 comes into contact with the upper end portion of the contact plate portion 56a. At this time, the upper and lower flange members 52 and 53 are moved to the disengagement position. When the door 3 further rotates toward the closed position, the contact roller R2 gets over the contact plate 56a and is separated from the contact plate 56a at that moment. Then, as shown in FIG. 14, the lock member 56 is rotated to the lock position by the urging force of the urging means 57.

  When the lock member 56 is rotated to the lock position, the second contact plate portion 56d formed on the back surface of the contact plate portion 56a (the surface facing the back side of the housing 2) faces the contact roller R2. To do. Accordingly, when the door 3 is opened and rotated from the closed position to the predetermined position (third position), the contact roller R2 comes into contact with the second contact plate portion 56d. Thereby, the opening rotation beyond the predetermined position of the door 3 is prevented. Further, in a state where the lock member 56 is rotated to the lock position, the upper and lower flange members 52 and 53 biased by the biasing means 55 try to move from the engagement release position toward the engagement position side. However, the upper surface of the flange portion 52b of the upper flange member 52 and the upper surface of the flange portion 53b of the lower flange member 53 are substantially in contact with the engagement rollers 62A and 62B. Therefore, the upper and lower flange members 52 and 53 hardly move from the engagement release position toward the engagement position side.

  When the door 3 is further closed and rotated to reach the closed position, as shown in FIG. 14, the engagement recesses 52c and 53c of the flange portions 52b and 53b and the engagement rollers 62A and 62B face each other. As a result, the upper and lower flange members 52, 53 are moved to the engagement position by the urging means 55, and the engagement rollers 62A, 62B are fitted into the bottom portions of the engagement recesses 52c, 52d, respectively. As a result, the flanges 52b and 53b and the engagement rollers 62A and 62B are reliably engaged, and the door 3 is engaged in the closed position.

  An operation plate 64 is provided on the upright plate portion 63b so as to be movable within a predetermined range in the vertical direction via an axis J6. Between the operation plate 64 and the upright plate portion 63b, a reset plate (intermediate member) 65 is provided so as to be movable within a predetermined range in the vertical direction via the shaft J6 and the shaft J7. An urging means 66 composed of a coil spring or other springs is provided between the spring 65 and the coil 65. The urging means 66 urges the operation plate 64 downward and urges the reset plate 65 upward so that the operation plate 64 and the reset plate 65 approach each other. Thus, except when the cylinder lock 67 described later is operated, the operation plate 64 is positioned at the lower limit position, and the reset plate 65 is positioned at the upper limit position.

  A cylinder lock (lock) 67 is provided on the base 63 a of the position adjustment plate 63 with its longitudinal direction oriented in a direction substantially perpendicular to the front surface of the door 3. The cylinder lock 67 passes through an insertion hole 3 a (see FIG. 3) formed in the door 3 and protrudes forward from the door 3. Here, the left and right positions of the cylinder lock 67 and the insertion hole 3a may not match due to manufacturing error or model, but in that case, the position adjustment plate 63 is attached to the door side mounting plate 61 in the left and right direction. By appropriately adjusting the position, the cylinder lock 67 can be reliably inserted into the insertion hole 3a. Of course, if the position adjustment plate 63 can be adjusted in the vertical direction with respect to the mounting plate 61, the vertical displacement between the cylinder lock 67 and the insertion hole 3a can be absorbed.

  An operation piece 67b having a substantially “<” shape is fixed to an end of the cylinder lock 67 on the side of the housing 2 of the cylinder shaft 67a. When a key (not shown) is inserted into the cylinder lock 67 and the operating piece 67b is rotated from the neutral position shown in FIG. 7 in the counterclockwise direction (one direction) to the unlocked position (opening operation), One end (the lower end in FIG. 7) abuts against the operation plate 64 located at the lower limit position, and the operation plate 64 is moved upward to a predetermined position against the urging force of the urging means 66. As will be described later, when the operation plate 64 moves upward to a predetermined position, the upper and lower flange members 52, 53 are thereby moved to the disengagement position. Therefore, a predetermined position of the operation plate 64 is also referred to as an engagement release position. When the operation plate 64 is moved upward, the reset plate 65 is located at the upper limit position, and therefore does not move upward as the operation plate 64 moves upward. Conversely, when the operating piece 67b is rotated from the neutral position in the clockwise direction (the other direction) to the reset position (reset operation), the upper end of the operating piece 67b comes into contact with the reset plate 65 positioned at the upper limit position and resets. The plate 65 is moved downward to a predetermined position (hereinafter referred to as a reset position) against the urging force of the urging means 66. At this time, since the operation plate 64 is located at the lower limit position, it does not move downward as the reset plate 65 moves downward.

  The operation plate 64 is formed with two protrusions 64a and 64b. When the operation plate 64 is moved upward from the lower limit position when the door 3 is located at the closed position, the one projecting portion 64a abuts on the inclined surface 56c formed at the lower end portion of the lock member 56 and locks. The member 56 is rotated from the lock position to the lock release position. The other protrusion 64b abuts on an engagement piece 53d formed on the lower flange member 53, and at the same time the one protrusion 64a rotates the lock member 56 from the lock position to the unlock position, the lower flange The member 53 is moved from the engagement position to the engagement release position. Thus, when the lower hook member 53 is moved upward by the operation plate 64, the lock member 56 is simultaneously rotated from the lock position to the unlock position by the operation plate 64, so that the lower hook member 53 is moved. When the operation plate 64 is moved from the engagement position to the release position, the lower hook member 53 does not hit the lock member 56. At the same time as the lower hook member 53 moves upward from the engagement position to the engagement release position, the upper hook member 52 moves downward from the engagement position to the engagement release position.

  The reset plate 65 is formed with two protrusions 65a and 65b. One protrusion 65a includes a proximity switch or the like provided on the upright plate 63b when the reset plate 65 is moved downward from the upper limit position to the reset position when the door 3 is in the closed position. The reset switch RS is approached, and the reset switch RS is changed from the OFF state to the ON state. Thereby, the game interrupted by opening the door 3 from the closed position is resumed. The other protrusion 65b is located between the engagement release position and the engagement position, even though the door 3 is positioned at the closed position, and the lower flange 53 is not moved to the engagement position. When the engaging rollers 62A and 62B do not reach the bottoms of the engaging recesses 52c and 53c of the flange portions 52b and 53b and are engaged in an incomplete state, the reset plate 65 When it moves downward, it comes into contact with the upper surface of the engagement piece 53e of the lower hook member 53 and moves the lower hook member 53 to the engagement position. Thereby, when the reset switch RS is reset (switched from the OFF state to the ON state), the flange portions 52b and 53b and the engagement rollers 62A and 62B are configured to be reliably engaged. In other words, unless the flanges 52b and 53b and the engagement rollers 62A and 62B are securely engaged, the reset switch RS will not be switched from the OFF state to the ON state, and the game cannot be resumed. Yes. Thereby, the door 3 closed in an incomplete state is opened to prevent the game from being illegally performed.

  In the pachislot machine 1 having the above configuration, it is assumed that the door 3 is now closed. In this state, as shown in FIG. 3, the outer side portion of the housing-side mounting plate 51 enters the door-side mounting plate 61. Accordingly, in order to open the door 3 illegally, for example, when a wire (not shown) or the like is inserted from the gap indicated by the symbol A between the housing 2 and the door 3 to move the upper hook member 52 downward. The tip of the wire inserted from the gap A is inserted between the side wall 61 a and the side of the mounting plate 51 in front of the mounting plate 51 and further inserted into the housing 2. The tip of the wire that has passed through the side portion of the wire abuts against the side wall portion 61b and cannot be inserted further into the housing 2. In this state, even if the upper hook member 52 is moved downward by the wire hooked on the upper hook member 52, the length of the wire from the hooking portion to the tip edge with respect to the upper hook member 52 (= the attachment plate 51 and Since the distance between the side wall portion 61 b and the side wall portion 61 b is short, the wire is easily detached from the upper flange member 52. For this reason, it becomes very difficult to move the upper flange member 52 illegally. The same applies to the case where the lower heel member 53 is moved illegally. Therefore, the door 3 cannot be opened illegally.

  Even if the upper hook member 52 or the lower hook member 53 can be moved from the engagement position toward the engagement release position side by the wire, before they reach the engagement release position from the engagement position. The lower flange member 53 abuts against the lock member 56. Therefore, even if the upper hook member 52 and the lower hook member 53 can be slightly moved from the engagement position, they cannot be moved to the engagement release position. Therefore, the engagement state between the flange portions 52b and 53b and the engagement rollers 62A and 62B is not released. Thereby, the unauthorized opening operation of the door 3 is prevented more reliably.

  Further, the upper and lower hook members 52, 53 are temporarily moved to the disengagement position regardless of the presence of the unauthorized movement preventing mechanism for the upper and lower hook members 52, 53 as described above. , 53b and the engagement rollers 62A, 62B are disengaged, the door 3 of the pachislot machine 1 cannot be opened illegally. That is, as described above, when the contact roller R2 gets over the contact plate portion 56a of the lock member 56 as the door 3 moves from the open position side to the close position side, the lock member 56 returns to the lock position. When the door 3 is to be opened in this state, the contact roller R2 comes into contact with the second contact plate portion 56d and tries to rotate the lock member 56 in the direction from the unlock position to the lock position. However, the lock member 56 cannot rotate beyond the lock position. Accordingly, when the contact roller R2 hits the second contact plate portion 56d, the door 3 cannot be opened any further. As a result, the door 3 is prevented from being illegally opened, and as a result, fraud to the game machine is more reliably prevented.

  The door 3 located in the closed position can be opened by opening the cylinder lock 67. In that case, first, a key is inserted into the cylinder lock 67, and the operating piece 67b is rotated from the neutral position to the unlocked position in the counterclockwise direction in FIG. Then, the upper and lower flange members 52 and 53 move from the engagement position to the engagement release position, and the engagement rollers 62A and 62B escape from the engagement recesses 52c and 53c, respectively. At the same time, the lock member 56 rotates from the lock position to the lock release position. Therefore, the door 3 can be opened and rotated from the closed position by maintaining the state.

  Here, when the door 3 is rotated from the closed position to the open position side by a predetermined minute angle (for example, about 2 °) or more, the operation plate 64 is separated from the lower flange member 53 and the lock member 56. As a result, the lower flange member 53 attempts to move downward toward the engagement position, and the lock member 56 attempts to rotate from the lock release position to the lock position. If the operation plate 64 moves away from the lower flange member 53 and the lock member 56 and simultaneously the lock member 56 rotates to the lock position, the contact roller R2 hits the contact plate portion 56a of the lock member 56, and as a result, the door. 3 is prevented from opening. However, the lock member 56 does not return to the lock position until the contact roller R2 passes through the contact plate portion 56a of the lock member 56 in the direction from the inside to the outside of the housing 2.

That is, when the operation plate 64 is separated from the lower hook member 53 and the locking member 56, so that upper and lower hook member 52, 53 is moved from the disengaged position to the engaged position, the upper surface of the hook 52b and The lower surface of the flange 53b immediately abuts against the engaging rollers 62A and 62B. Thereby, the movement of the upper and lower flange members 52 and 53 toward the engagement position is prevented. Then, the lock member 56 that has started to turn to the lock position immediately hits the upper end portion of the lower flange member 53, and can no longer turn to the lock position. Such a state is maintained until the contact roller R2 passes through the contact plate portion 56a of the lock member 56. Therefore, the door 3 can be opened and rotated to the open position. When the door 3 rotates from the closed position toward the open position, a stop device (not shown) provided in the pachislot machine 1 detects the opening operation of the door 3 and automatically interrupts the game. The interrupted game cannot be resumed unless the reset switch RS is turned on.

  The opened door 3 can be automatically engaged with the closed position by simply rotating it to the closed position. As described above, when the door 3 is moved to the closed position, the contact roller R2 hits the contact plate portion 56a and rotates the lock member 56 from the lock position to the lock release position. The collar member 52 and the lower collar member 53 are moved from the engagement position to the engagement release position. When the contact roller R2 passes through the contact plate portion 56a, the lock member 56 returns from the unlock position to the lock position. Thereafter, the upper and lower flange members 52, 53 move from the disengagement position to the engagement position, and the flange portions 52b, 53b engage with the engagement rollers 62A, 52B, respectively. As a result, the door 3 is locked to the housing 2 in the closed position.

  In order to resume the game that was interrupted with the opening operation of the door 3, as described above, the key is inserted into the cylinder lock 67 and the operating piece 67b is rotated from the neutral position to the reset position in the clockwise direction in FIG. Let Then, the reset plate 65 approaches the reset switch RS and switches it from the OFF state to the ON state.

  When the upper and lower flange members 52, 53 are not moved to the engagement position during the reset operation and the flange portions 52b, 53b are not correctly engaged with the engagement rollers 62A, 62B, the reset plate 65 Thus, the upper and lower flange members 52 and 53 are moved to the engagement position. Therefore, when the reset switch RS is turned on, the flanges 52b and 53b and the engagement rollers 62A and 62B are always properly engaged. In other words, when the upper and lower flange members 52 and 53 cannot move to the engagement position and the flange portions 52b and 53b and the engagement rollers 62A and 62B are not correctly engaged, the operating piece 67b. And the reset plate 65 cannot move to the reset position. Therefore, the reset switch RS does not switch from the OFF state to the ON state. Therefore, it is possible to prevent a situation in which the door 3 is opened and fraud is performed after the game is resumed.
