Description

  In the pachinko gaming machine, the front door of the variable winning device is forcibly opened by an external operation, and a variable of the gaming machine for preventing an illegal act of winning a winning ball by winning a ball in the open winning opening It relates to a winning device.

  As a pachinko machine, there is one having a variable winning device at a specific winning opening. The variable winning device is normally de-energized with a driving device such as a solenoid to keep the front door closed so that the ball does not win, while the driving device is operated to turn the front door when a specific gaming state occurs. Make the ball easier to enter the winning opening as an open state.

  However, when the drive unit is not operating, a fraudulent act may be performed in which a wire or other tool is intruded from outside and forcibly opened by forcibly opening the front door to illegally win a prize ball. If the act is performed, the hall side will suffer a great deal of damage.

  For example, Patent Documents 1 and 2 disclose variable winning devices for gaming machines that prevent such illegal acts. The one disclosed in Patent Document 1 is such that a front door (winning guide member) is rotatably supported on a rotation shaft, and the front door is raised and tilted by the vertical movement of the brake piece. It is possible to prevent the front door in the standing state from being tilted by an improper external force by the engagement of the protrusion provided on the engaging portion and the engaging portion provided on the winning guide member.

  However, in the above-mentioned, in addition to the protruding portion protruding toward the front of the gaming machine, that is, the player, since the engaging portion is provided on the front door, a thin wire or the like is provided from the side of the front door. There is a problem that the brake piece can be pulled up by intrusion, and thus the lock is released and the front door is opened illegally.

  Patent Document 2 discloses that when an external force is applied to the front door to turn the front door (winning door) from the closed position to the open position, the first hit of the notch portion in the swing arm is disclosed. The contact surface is in contact with the engagement pin in the head cover from below. Thus, the counterclockwise rotation of the swing arm is prevented and the front door is maintained in the closed position.

  However, even in the above, the engaging portion between the engaging pin and the first contact surface is provided toward the player, so that a thin wire or the like enters from the side of the front door and presses the head cover backward. It is possible to do this, so that the lock is released and the front door can be opened illegally.

  As described above, the conventional variable prize-winning device cannot necessarily prevent this from the viewpoint of preventing fraud.

  An object of the present invention is to provide a variable winning device for a gaming machine that can reliably prevent unauthorized opening of a front door using a tool such as a wire.

A variable winning device for a gaming machine according to the present invention made to solve the above-mentioned problems is a slider that slides in the front-rear direction by a drive source, and that opens and closes the front door by being pivoted up and down by the sliding of the slider. A variable prize device for a gaming machine comprising: a door opening / closing member to be turned; and a stopper that is turned up and down by a slider to restrict the turning of the door opening and closing member;
The door opening / closing member is provided with a lock claw having a lock surface facing the rear of the gaming machine,
The stopper is provided with a forward-facing lock piece whose tip is in contact with the lock surface and restricts the upward rotation of the door opening and closing member, and this stopper is arranged behind the door opening and closing member. .

  In the above-described invention, it is preferable that the thickness of the lock piece is equal to or less than the thickness of the lock claw, and the front end surface of the lock piece is made smaller than the lock surface.

  The upper part of the slider is provided with a protrusion for rotating the stopper upward, and the lower part of the stopper is a member for sliding the protrusion to disengage the lock piece tip from the lock surface. A mating slope may be provided to place the slider below the stopper.

  Further, the slider is provided with a recess, and the door opening / closing member is provided with a protrusion for engaging with the front and rear wall surfaces of the recess to rotate the door opening / closing member up and down. Can be placed rearward.

  In the game machine variable winning device according to the present invention, when the front door is standing, the lock piece of the stopper is brought into contact with the lock surface of the door opening / closing member and locked, so that a tool such as a wire is inserted from the front of the gaming machine. Even if the door opening / closing member is rotated, it cannot be rotated. In addition, since the stopper is disposed behind the door opening / closing member, even if it is attempted to flip the stopper upward with a tool, the door opening / closing member in the middle prevents the tool from entering, so the stopper cannot be lifted up. Therefore, unauthorized opening of the front door can be reliably prevented.

  Hereinafter, embodiments of the present invention will be described.

  FIG. 1 is a diagram showing a large winning device in which the variable winning device of the present invention is used, and a winning opening 1 is opened and closed by a front door 6. The variable winning device is arranged inside this.

  2 and 3 are views showing the variable winning device of the present invention. In this state, the front door 6 is erected and the winning opening 1 is in a closed state. In the figure, 2 is a solenoid as a driving device, 3 is a slider, 4 is a door opening / closing member, and 5 is a stopper. The slider 3 is disposed behind the door opening / closing member 4 below the stopper 5. 2 and 3, the left side is the gaming machine front side, and the right side is the gaming machine rear side.

  The solenoid 2 has a plunger 21, and when the solenoid 2 is not energized, the plunger 21 is urged rearward by a return spring (not shown) and thus protrudes from the solenoid coil and moves to the rear side of the gaming machine. However, it is attracted and retracted by energization and moves to the front side of the gaming machine. Since the slider mounting portion 33 is fitted into the plunger 21 and the slider 3 is mounted, the slider 3 slides in the front-rear direction as the plunger 21 moves.

  The slider 3 is L-shaped when viewed from the upper surface formed by a slider mounting portion 33 and a substantially rectangular slider portion 34 suspended from one end of the slider mounting portion 33. Are spaced apart from each other by a recess 31 that engages with the door opening / closing member 4, a protrusion 32 that rotates the stopper 5 upward on the rear side, and an opposite surface on which the slider mounting portion 33 is suspended. And a pair of guide walls 35 parallel to the sliding direction. The concave portion 31 has an upward U-shape and has a front side wall surface 31a and a rear side surface 31b provided perpendicular to the sliding direction, and the protrusion 32 is rectangular and is perpendicular to the sliding direction. It has a rear side surface 32b.

  The door opening / closing member 4 has a plate shape and pivots in the vertical direction around the support shaft 41. The door opening / closing member 4 protrudes in the direction of the support shaft 41 and engages with the recess 31 to rotate the door opening / closing member 4 in the vertical direction. A protrusion 42 to be protruded, a lock claw 43 protruding from the support shaft 41 toward the outer periphery, and an upper lever 44 and a lower lever protruding from the lock claw 43 at a required interval in the opposite direction across the support shaft 41 45. The lock claw 43 is provided with a lock surface 43a that is a step toward the rear of the gaming machine.

  The stopper 5 has a plate shape equal to or less than the thickness of the door opening / closing member 4, and rotates in the vertical direction around the support shaft 51. The stopper 5 protrudes from the support shaft 51 toward the outer periphery and contacts the lock surface 43 a. In order to release the rotation lock of the door opening / closing member 4 by sliding the lock piece 52 that restricts the upward rotation of the door opening / closing member 3 and the protrusion 32 of the slider 3 to rotate upward. And an engaging protrusion 54 having an engaging surface 54a that faces the engaging inclined surface 53 and engages with the rear side surface 32b. The front end surface of the lock piece 52 is formed smaller than the lock surface 43a.

  The front door 6 rotates in the vertical direction about the support shaft 61, but has a door main body 62 that opens and closes the winning opening 1, and a working pin 63 that extends to the side of the door main body 62. The action pin 63 faces between the upper and lower levers 44 and 45, and the front door 6 is opened and closed by the rotation of the door opening and closing member 4.

  FIG. 4 is an exploded perspective view of the variable winning device, 7 is an attachment member for fixing the solenoid 2, and 8 is a shaft for pivotally mounting the door opening / closing member 4 and the stopper 5. The mounting member includes shafts 81 and 82. A guide wall 83 that is inserted between the pair of guide walls 35 to ensure the sliding of the slider 3 is provided on the surface of the mounting member 8 on which the shafts 81 and 82 are projected. FIG. 5 is a perspective view of the left side of the variable winning device, and shows a state where the plunger 21 is fitted in the groove of the slider mounting portion 33. The attachment members 7 and 8 are fixed with a gap slightly larger than the thickness of the door opening and closing member 4, and the door opening and closing member 4 and the stopper 5 are pivotally attached to the shafts 81 and 82 in the gap.

  If the upper end of the front door 6 in the standing state shown in FIG. 3 is pulled to open it illegally, a counterclockwise force acts on the front door 6 around the support shaft 61. At this time, the action pin 63 comes into contact with the upper lever 44, and a clockwise force acts on the door opening / closing member 4 around the support shaft 41. However, since the lock surface 43a is in contact with the tip of the lock piece 52, the clockwise rotation of the door opening / closing member 4 is restricted, and therefore the front door 6 cannot be opened (FIG. 6).

  In the state of FIG. 3, the stopper 5 is disposed behind the door opening / closing member 4, the front end surface of the lock piece 52 is smaller than the locking surface 43 a, and the thickness of the stopper 5 is equal to or less than the thickness of the door opening / closing member 4. Therefore, the lock piece 52 is hidden behind the lock claw 43 and cannot directly touch the stopper 5 from the front side. Therefore, even if a wire or the like is inserted from the front side, the stopper 5 cannot be lifted up because the lock claw 43 or the door opening / closing member 4 interferes. Further, since the slider 3 has already moved rearward by the return spring and the rear side surface 32b and the engaging surface 54a are in contact with each other, in this state, when the slider 3 is pressed rearward, the stopper 5 is centered on the support shaft 51. However, since the lock piece 52 comes into contact with the door opening / closing member 4 and the counterclockwise rotation is restricted, the slider 3 cannot move.

  When the lock is released and the front door 6 is tilted, the solenoid 2 is energized to attract the plunger 21 and move forward. As a result, the slider 3 is also slid forward, so that the protrusion 32 slides below the engaging slope 53 and rotates the stopper 5 upward (FIG. 7). Since the tip end of the lock piece 52 is pulled up from the lock surface 43a, the lock is released and the door opening / closing member 4 can be rotated upward.

  Thereafter, the forward movement of the plunger 21 causes the rear wall surface 31 b of the recess 31 to abut against the protrusion 42 of the door opening / closing member 4, and a clockwise force acts on the door opening / closing member 4. At this time, since the lock has already been released and the door opening / closing member 4 can be turned upward, the lower lever 45 kicks up the action pin 63 of the front door 6. Thereby, the front door body 62 is tilted forward by its own weight, and the front door 6 is opened until the action pin 63 collides with the upper lever 44 (FIGS. 8 and 9). In this state, the front door 6 can be opened and closed as much as the action pin 63 can freely move between the upper lever 44 and the lower lever 45. This is to prevent the ball from being caught between the glass plates.

  When the front door 6 is closed after a predetermined time has elapsed, the energization of the solenoid 2 is cut off, and the plunger 21 is projected by the return spring and moved rearward. As a result, the front wall surface 31a of the recess 31 collides with the protrusion 42, so that the door opening / closing member 4 is rotated downward, and the upper lever 44 pushes down the action pin 63 of the front door 6 (FIG. 3). As a result, the front door 6 stands up in a closed state. Further, the pushing up of the engaging slope 53 by the protrusion 32 is released, and the rear side surface 32b and the engaging surface 54a come into contact with each other. Therefore, the stopper 5 is rotated downward, so that the tip of the locking piece 52 contacts the locking surface 43a. It comes in contact and returns to the locked state.

  As described above, the variable winning device of the present invention has the door of the lock piece 52 abutted against the lock surface 43a facing backward in the locked state, so even if a tool such as a wire is inserted from the front of the gaming machine, The opening / closing member 4 cannot be rotated. Further, since the door opening / closing member 4 obstructs the entry of the tool, the stopper 5 cannot be lifted upward, and the engagement between the lock surface 43a and the lock piece 52 cannot be released. Therefore, the variable winning device of the present invention has a great advantage that it is possible to reliably prevent the front door from being illegally opened.
