For the pachinko machine 1 installed in the amusement hall, maintenance work such as inspection and replacement of each component arranged on the back surface of the inner frame 3 is performed in a key hole provided at the right end of the inner frame 3 when viewed from the front. On the other hand, after performing unlocking operation with a dedicated key, the inner frame 3 is swung to the front side with respect to the outer frame 2, and a hand or a tool is inserted from the opening (gap) portion between the outer frame 2 and the inner frame 3. Is done.

  The front upper door 4 is formed with a substantially circular opening 4a at a substantially central portion thereof. The opening 4a is covered with a transparent glass plate 6 attached to the back surface of the front upper door 4, and a game area (not shown) having a prize opening or the like (not shown) is played through the glass plate 6. It is comprised so that a person can visually recognize. The pachinko machine 1 is a first type pachinko gaming machine in which the game progresses while changing according to the behavior of a ball driven into the game area provided through the glass plate 6, and since it is a known one, Description is omitted.

  On the front surface of the front lower door 5, an upper plate 7 for storing a sphere is provided protruding forward. A lower plate 8 for storing a ball that could not be stored in the upper plate 7 is formed in a box shape having an open upper surface below the lower front door 5 and in the lower part of the inner frame 3. . On the right side of the lower plate 8 (right side in FIG. 1), an operation handle 9 that is operated by the player to drive the ball into the game area is disposed.

  Next, with reference to FIG. 2, the opening / closing mechanism of the inner frame 3 that allows the inner frame 3 to be closed only when the inner frame 3 is opened to a certain amount or more with respect to the outer frame 2 of the pachinko machine 1 will be described in detail. To do. FIG. 2 is an exploded perspective view showing the upper hinge member 10 and its peripheral components. In FIG. 2, only a part of the outer frame 2 and the inner frame 3 is shown.

  The opening / closing mechanism of the inner frame 3 with respect to the outer frame 2 is supported by a hinge member 10 fixed to the outer frame 2, an inner frame 3 pivotally supported on the hinge member 10, and a swingable pivot on the inner frame 3. And a coil spring 14 for applying a biasing force to the lock lever 13.

  The inner frame 3 is provided with a rotating shaft 3a protruding upward at the upper left portion thereof. The rotating shaft 3a is engaged with a shaft hole 11a of the hinge member 10 fixed to the outer frame 2 in a state after assembly, and the inner frame 3 is centered on the rotating shaft 3a with respect to the outer frame 2. It can be turned. The rotating shaft 3a is formed with a constant outer diameter on the upper side that is smaller than the outer diameter of the shaft hole 11a, and the lower side is configured with a stepped shaft larger than the outer diameter of the shaft hole 11a. 3 is restricted, and an arrangement space for the lock lever 13 constituting the support structure of the inner frame 3 is formed around the rotation shaft 3a. Around the rotation shaft 3a of the inner frame 3, a shaft hole 3b that supports the rotation shaft 13a of the lock lever 13 is formed along the same axial direction as the rotation shaft 3a. A spring bearing shaft 3c is provided to project upward along the same axial direction as the rotation shaft 3a and the shaft hole 3b on the clockwise side in the top view around the rotation shaft 3a (left side of the shaft hole 3b in FIG. 2). ing.

  The outer frame 2 is configured by combining four plate members in a box shape vertically and horizontally, and a hinge member 10 is caulked and fixed to the upper left corner by four caulking pins 15. The hinge member 10 is formed from a flat plate-like upper plate 11 which is formed in a substantially rectangular plate shape and has a shaft hole 11 a at an end portion, and a side plate 12 which extends downward from one side of the upper plate 11.

  On the inner surface side (lower side in FIG. 2) of the upper plate 11, an annular groove 11b having a sawtooth-like tooth profile surface formed in a part of the outer peripheral surface is recessed. The lock shaft 13b of the lock lever 13 circulates in the groove 11b as the inner frame 3 opens and closes. When the inner frame 3 is opened to a certain amount or less and then closed, the lock shaft 13b of the lock lever 13 is moved into the groove 11b. The closing of the inner frame 3 is regulated by engaging with the tooth profile surface.

  The upper plate 11 and the side plate 12 of the hinge member 10 are each provided with two attachment holes 11c and 12c through which the four caulking pins 15 are inserted. After the four caulking pins 15 have been inserted through the mounting holes 11c and 12c and the outer frame 2, respectively, the tip of each caulking pin 15 is caulked, whereby the hinge member 10 is fixed to the outer frame 2. Is done.

  The lock lever 13 is a member that is interposed between the inner frame 3 and the outer frame 2 to restrict the closing of the inner frame 3 when the inner frame 3 of a certain amount or less is opened. The lock lever 13 is provided with a rotating shaft 13a projecting downward from one end portion (left end portion in FIG. 2) through the shaft hole 3b of the inner frame 3, and centering on the rotating shaft 13a. The lock lever 13 is pivotally supported by the inner frame 3 so as to be swingable.

  At the end of the lock lever 13 opposite to the rotary shaft 13a, a lock shaft 13b having a tooth-shaped surface in part protrudes upward. The lock shaft 13b is disposed in an annular groove 11b that is recessed in the upper plate 11 of the hinge member 10 in a state after assembly. On the outer peripheral surface of the groove 11b, a tooth-shaped surface is partially formed at a position facing the tooth-shaped surface of the lock shaft 13b, and a part of the teeth on the tooth-shaped surface mesh with each other to move toward the closing direction of the inner frame 3. Movement is restricted.

  A spring receiving shaft 13c is projected from the center of the lock lever 13 toward the rotary shaft 13a in the substantially same direction as the lock shaft 13b. One end of a coil spring 14 that applies an urging force to the lock lever 13 is hung on the spring receiving shaft 13c. The other end of the coil spring 14 is hung on a spring receiving shaft 3c that protrudes upward from the inner frame 3 to apply a biasing force to the lock lever 13 in the clockwise or counterclockwise direction as viewed from above. .

  The coil spring 14 is applied to spring receiving shafts 3 c and 13 c provided on the inner frame 3 and the lock lever 13, respectively, and applies an urging force to the lock lever 13. In the single product state, the coil spring 14 is formed with a length shorter than the distance between the shafts of the spring bearing shafts 3c and 13c in the assembled state, and applies a biasing force in a direction to contract between the spring bearing shafts 3c and 13c. It consists of a coil spring. The coil spring only needs to be able to apply an urging force in the direction of contraction between the spring bearing shafts 3c and 13c by elastic deformation. For example, the spring material is metal, synthetic resin, rubber, or the like. Any of these materials may be used, and a biasing force may be applied using a spring having a winding direction and a shape different from those of the present embodiment. That is, an annular rubber may be applied to the two spring bearing shafts 3c and 13c to apply a biasing force.

  Next, with reference to FIGS. 3 and 4, the operation of the pachinko machine 1 will be described focusing on the operation of the lock lever 13. 3 and 4 show the arrangement position of the lock lever 13 for each open state of the inner frame 3 when the pachinko machine 1 is viewed from above, and FIG. 3A shows the closed state of the inner frame 3. FIG. 3B shows a state in which the inner frame 3 is slightly opened from the closed state and the movement of the inner frame 3 to the closed side is restricted. FIG. 3C is an enlarged view of a portion IIIc in FIG. 3B, in which the lock shaft 13b and the hinge of the lock lever 13 in a state where the movement of the inner frame 3 in the closing direction is restricted. The relative position with the cyclic | annular groove | channel 13b provided in the member 10 is illustrated. 4A shows an open state in which the inner frame 3 is opened up to a position where the movement restriction of the inner frame 3 toward the closing direction is released, and FIG. 4B shows the open state shown in FIG. The state of the process in which the inner frame 3 is closed from the open state is illustrated.

  3 and 4, only the members related to the opening / closing mechanism of the inner frame 3 and the mechanism for restricting the movement of the inner frame 3 to the closing side are shown, and other members are omitted. Show. 3 and 4, the spring shape of the middle portion of the coil spring 14 is indicated by a one-dot chain line in order to simplify the drawing and facilitate understanding. Further, in FIG. 3B, the shape that is not visible in the top view of the pachinko machine 1 and is originally indicated by a dotted line is indicated by a solid line for easy understanding.

  As shown in FIG. 3A, in a state where the inner frame 3 is closed, the coil spring 14 is away from the rotation shaft 3a of the inner frame 3 with respect to the rotation shaft 13a of the lock lever 13 (FIG. 3). (Right side of (a)). The coil spring 14 applies a biasing force in a direction in which the spring receiving shaft 13c of the lock lever 13 and the spring receiving shaft 3c of the inner frame 3 are brought close to each other. For this reason, the lock lever 13 is given a biasing force in the clockwise direction around the rotation shaft 13a of the lock lever when viewed from above, and the lock shaft 13b of the lock lever 13 rotates in the clockwise direction of the lock shaft 13b. The lock lever 13 is disposed in contact with the outer peripheral surface disposed on the side.

  In the closed state of the inner frame 3, the inner frame 3 cannot be moved to the open side by a known locking device unless the unlocking operation of the dedicated key with respect to the keyhole is performed. If the unlocking operation of the dedicated key is performed on the locking device, or if an operation equivalent to the unlocking operation of the dedicated key is performed illegally using a wire etc., the locking device is unlocked Thus, the inner frame 3 can be opened to the front side by pulling the inner frame 3 to the front side.

  When the inner frame 3 is opened, the lock shaft 13b of the lock lever 13 is urged clockwise around the rotation shaft 13a of the lock lever 13 as shown in FIGS. 3 (b) and 3 (c). Then, it moves downward along the outer peripheral surface on the right side of the annular groove 11b while being pressed against the tooth profile surface provided in the groove 11b. Specifically, one of the teeth provided on the lock shaft 13b of the lock lever 13 and the numerous teeth provided on the outer peripheral surface of the annular groove 11b is opposed to each other in a right upward direction. Then, the teeth facing each other move in order. While the inner frame 3 is being opened, the lock shaft 13b is pressed against the tooth profile surface of the groove 11b. When the inner frame 3 is to be closed halfway, the pair of opposing teeth mesh with each other. The lock shaft 13b is restricted from moving in the upper right direction along the outer peripheral surface of the groove 11b. As the movement of the lock shaft 13b in the upper right direction is restricted, the movement of the inner frame 3 in the closing direction is restricted.

  When the inner frame 3 is further opened from the state shown in FIG. 3B, the arrangement position of the spring receiving shaft 3c of the inner frame 3 relative to the spring receiving shaft 13c of the lock lever 13 is on the left side (counterclockwise) of the rotating shaft 13a of the lock lever 13. It is arranged on the rotation direction side). For this reason, the direction in which the urging force is applied to the lock lever 13 is reversed by the coil spring 14, and the lock lever 13 is urged counterclockwise around the rotation shaft 13a of the lock lever 13 in a top view. . As shown in FIG. 4A, the lock shaft 13b of the lock lever 13 is supported by being separated from the outer peripheral surface on the lower right side of the groove 11b and in contact with the outer peripheral surface side on the upper left side.

  When the closing is started after reaching the open state shown in FIG. 4A, the lock shaft 13b of the lock lever 13 passes through the upper left passage of the groove 11b as shown in FIG. 4B. To do. Since the teeth facing the tooth profile surface of the lock shaft 13b are not formed in the upper left passage of the groove 11b, even if the direction in which the biasing force is applied to the lock lever by the coil spring 14 is reversed in the middle, the central portion The engagement of the teeth is not caused by the peninsula-shaped projections of the ridges, and the lock shaft 13b moves to the upper right side without being restricted. According to the movement, the inner frame 3 moves toward the closing direction until reaching the closed state shown in FIG.

  Thus, according to the pachinko machine 1, in the opened state before the inner frame 3 reaches the opened state shown in FIG. 4A from the closed state, the lock frame 13 moves the inner frame 3 toward the closing direction. Is released and the movement of the inner frame 3 toward the closing direction is released by opening the inner frame 3 until the open state shown in FIG. 4A is reached. For this reason, when the inner frame 3 is opened by a small amount for the purpose of cheating, the inner frame 3 can be opened once and then closed, and the cheating is detected by the opening / closing operation of the inner frame 3. be able to.

  That is, when an unauthorized key is obtained, or when the locking device is unlocked with a wire or the like and a fraudulent act is attempted on the back side of the inner frame 3, the inner frame 3 is opened slightly to be illegal. A fraudulent act is performed in which the inner frame 3 is closed as it is by exchanging parts for operation or unauthorized operation. In this case, since a person stands to be a wall that blocks the view of a security camera or a store clerk and cheating is performed in the blind spot, it is difficult to detect cheating. In addition, increasing the number of security cameras or increasing the number of shop assistants to prevent this has led to an increase in the cost of the amusement hall and has become a problem. On the other hand, in the pachinko machine 1, even if an attempt is made to open the inner frame 3 by a small amount, the inner frame 3 can be opened once and then closed. It is possible to make it difficult to perform an action in the blind spot, and it is possible to easily detect fraud. Therefore, the crime prevention property of the pachinko machine 1 can be improved while suppressing the increase in the number of security cameras and shop assistants.

  Further, in a ratchet mechanism that is conventionally used for a seat chair or the like and restricts a certain amount of movement in one direction, the ratchet mechanism swings only in the direction in which the back surface rises with respect to the seating surface due to the engagement between the cam and the teeth. In addition, a plate-like member is provided that restricts the cam from being biased toward the teeth when the seating surface and the back surface are substantially overlapped. When the opening / closing mechanism of the inner frame 3 is constructed by following this structure, a plate-like member that restricts the cam from being biased toward the teeth is required in addition to the cam and the spring that biases the cam. It becomes. On the other hand, according to the pachinko machine 1, the urging direction of the lock lever 13 against the lock shaft 13b of the lock lever 13 and the tooth profile surface of the groove 11b by the coil spring 14 is switched from the direction in which the two parts approach each other. By this switching, when the lock shaft 13b of the lock lever 13 is closed from the open state shown in FIG. 4 (a), the lock shaft 13b passes through a path separated from the tooth profile surface of the groove 11b, and the inner frame 3 is closed and released. And go. For this reason, compared with the ratchet mechanism conventionally used for the seat chair etc. conventionally, a required number of parts can be reduced and manufacturing cost can be suppressed.

  In addition, the open state in which the closing restriction of the inner frame 3 is started is useful for suppressing an illegal act with respect to a small gap as the position where the opening of the inner frame 3 is started after the locking device is unlocked. This position is effective, and this position can be dealt with by changing the design position of one of the outer peripheral surfaces of the lock shaft 13b of the lock lever 13 or the groove 11b of the hinge member 10.

  When the store clerk inspects or replaces parts related to the game with the inner frame 3 opened, the store clerk moves in the closing direction with an open amount that can secure the work space for the store clerk according to the part layout at the time of design. It is preferable to set an opening amount for restricting movement in the closing direction so as to restrict the movement. The inspection work or the like is generally performed in a state where the inner frame 3 of the pachinko machine 1 protrudes from the aisle of the game hall. If a passerby collides with the inner frame 3 during the execution of the inspection work or the like, the inner frame 3 There is a risk that the operator is accidentally sandwiched between the outer frame 2 and the outer frame 2. In particular, since the inner frame 3 is heavy with a large number of game-related members incorporated therein, the risk is high. In the pachinko machine 1, since the movement of the inner frame 3 toward the closing direction when the inner frame 3 of a certain amount or less is opened, the danger of the operator being caught can be reduced. You can immerse yourself in work with peace of mind.

  Further, in this embodiment, a plurality of teeth are provided on the lock shaft 13b of the lock lever 13 and the outer peripheral surface of the groove 11b of the hinge member 10 so that the movement restriction in the closing direction is performed in many stages. Although the tooth profile surface is formed, the tooth profile surface may be constituted by a smaller number of teeth. Since at least one or more teeth (one or more steps) are formed on the outer peripheral surface of the groove 11b, the movement of the inner frame 3 toward the closing direction can be restricted at least once. Or it can be set as the pachinko machine 1 provided with the movement restriction | limiting function to the closing direction side of the inner frame 3 aiming at at least any one of ensuring of work space. Further, the object of restricting the movement toward the closing direction using the lock lever 13 is not limited to the inner frame 3, and other objects such as the front upper door (glass door) 4 to which the glass plate 6 is attached. It is good also as a member.

  Next, a pachinko machine 50 according to a second embodiment will be described with reference to FIG. In the pachinko machine 1 according to the first embodiment, when the inner frame 3 is opened to a certain amount or less, the lock shaft 13b of the lock lever 13 is biased by the coil spring 14 to the tooth profile surface of the groove 11b of the hinge member 10. Thus, the movement toward the closing direction is restricted only by a so-called mechanical mechanism that restricts the movement toward the closing direction. On the other hand, in the pachinko machine 50 according to the second embodiment, the front door 51 that supports the glass plate 6 is a target whose movement in the closing direction is restricted when the pachinko machine 50 is opened to a certain amount or less. In addition, the movement restriction in the closing direction is performed with electrical control.

  FIG. 5 is a perspective view of the pachinko machine 50 in the second embodiment, showing a state in which the front door 51 is opened. In FIG. 5, a member such as a nail or the like which is formed inside the arc-shaped rail on the front surface of the inner frame 3 and arranged in a game area into which a ball is driven, or which changes the flow path of the ball. Is omitted. Hereinafter, in the description of the second embodiment, the same parts as those in the first embodiment described above will be denoted by the same reference numerals and the description thereof will be omitted, and only different parts will be described.

  The front door 51 is a member provided with a glass plate 6, an upper plate for holding a sphere, and the like. The upper and lower two portions on one end side of the front door 51 are connected to the inner frame 3 via a hinge plate 51a and are pivotally supported by the inner frame 3 so as to be swingable to the front side. Further, a projection 51b protruding toward the back side is provided on the back surface of the front door 51. When the projection 51b is closed, a resin lock connected to the movable piece of the closing restriction solenoid 52 is provided. When the body 52a is disposed at a free position, it abuts. In this contact state, the front door 51 cannot be completely closed, and the movement of the front door 51 toward the closing direction is restricted. In a state where it cannot be completely closed, the locking device using the dedicated key is not locked to the key hole provided at the right end of the inner frame 3 when viewed from the front, and the front door 51 is kept open. The protrusion 51b is preferably disposed on the side away from the hinge plate 51a than on the hinge plate 51a side that is the rotation center of the front door 51. By disposing the hinge plate 51a at a position separated from the hinge plate 51a, the load applied to the protrusion 51b at the time of closing can be reduced, and the protrusion 51b and the lock body 52a contacting the protrusion 51b can be hardly damaged.

  The closing restriction solenoid 52 is composed of a general electromagnetic solenoid that electromagnetically operates a movable piece. When the solenoid is off (non-energized), the lock body 52a is pushed out to the right by a built-in spring. The lock body 52a is moved to the left energized position by an electromagnetic force equal to or greater than the spring force. In a state where the lock body 52a is disposed at the free position, the projection 51b of the front door 51 cannot contact the lock body 52a to close the front door 51, and only when the closing restriction solenoid 52 is turned on. Thus, the front door 51 can be closed. Further, when the lock body 52a is moved to the energized position, the projection 51b of the front door 51 is not in contact with the lock body 52a, and the front door 51 is closed without restricting movement in the closing direction. It can be. In this closed state, the front door 51 is locked by the locking device, and the front door 51 is not opened unless an unlocking operation with a dedicated key for the keyhole is performed.

  The opening detection sensor 53 is a sensor for outputting a signal indicating a certain amount or more of opening of the front door 51, and two elements are built in one side of the box-shaped main body in the same direction. It is composed of an infrared reflection type sensor. One of the elements is a light emitting element that emits infrared light, and the other is a light receiving element that receives infrared light. The light emitted from the light emitting element outputs an off signal when the front door 51 is disposed on the front side of the open detection sensor 53, and the front door 51 is opened approximately 90 degrees or more, so that the open detection sensor 53 is arranged at a position to output an ON signal when it is off the front side. Note that the sensor for outputting a signal indicating that the front door 51 is opened in a certain amount or more is not limited to the infrared reflection type sensor described above. The front door 51 has a movable piece that is pressed against the front door 51 while the front door 51 is opened to a certain amount or less, and the front door 51 is moved from the movable piece only when the front door 51 is opened by a certain amount or more. Any other type of sensor such as a mechanical limit switch that outputs an off signal at a distance may be used.

  Here, the game area exposed when the front door 51 having the glass plate 6 is opened will be described. The game area is an area that is formed on one surface of the game board 54 fixed to the inner frame 3 (front door 51 side) and a ball game using a ball as a game medium is performed. In this game area, an arc-shaped rail that guides the ball, and a prize for paying out a certain amount (5 in this embodiment) as a winning ball when the ball formed in the rail enters. The symbol 55 is changed as a necessary condition to enter the winning hole 55 and the winning hole 55, and a predetermined symbol (a combination of three identical symbols in this embodiment) is selected when winning an internal lottery. LCD 56 for displaying and generating big wins When a big win for displaying predetermined symbols on the LCD 56, a predetermined time (for example, until 30 seconds have passed or 10 balls have been won) is opened so that the balls can easily win. The grand prize winning port 57 and the like are provided. The front door 51 is configured to be openable in order to adjust the ease of entering the ball for each pachinko machine, while the ball is clogged in the game area. Since the illegal act of illegally winning the ball 57 or illegally opening the grand prize opening 57 other than the opening time is easily performed, the game area is normally covered with the front door 51 and the locking device It is in a locked state.

  Next, the electrical configuration of the pachinko machine 50 will be described with reference to FIG. FIG. 6 is a block diagram showing an electrical configuration of the pachinko machine 50. The pachinko machine 50 has a main control board C that mainly controls a game performed in the game area on the front surface of the game board 54 by a player, and a payout motor 25 based on an instruction from the main control board C to win a prize.

Closure rules based A door control board F which controls the operation of the solenoid 52 is provided.

  The control boards C, H, D, L, E, and F are arranged on the back surface of the inner frame 3, and maintenance work such as inspection and replacement of each part is performed after the unlocking operation with the dedicated key. 2, the inner frame 3 is swung to the front side, and a hand, a tool, or the like is inserted from an opening (gap) portion between the outer frame 2 and the inner frame 3. Further, each control board C, H, D, L, E, F is equipped with an MPU as a one-chip microcomputer that is an arithmetic unit, and various programs executed by the MPU and fixed value data are stored in the MPU. Built-in ROM, RAM which is a memory for temporarily storing various data when executing the control program stored in the ROM, and various circuits such as an interrupt circuit, a timer circuit and a data transmission / reception circuit are incorporated. ing. The program of the flowchart shown in FIG. 7 is stored in the ROM of the MPU of the door control board F as a part of the control program.

  The main control board C and the payout control board H are connected to another input / output device 26 such as a detection switch for detecting a winning ball in the winning openings 55 and 57 and a paying ball.

  Next, of the processes executed by the pachinko machine 50 configured as described above, the process related to the opening / closing operation of the front door 51 will be described with reference to the flowchart of FIG. FIG. 7 is a flowchart of a door closing restriction process that constitutes a part of the main process executed on the door control board F. This door closing regulation process is a process performed in the main process of the door control board F. The main process includes an initialization process for initializing the RAM when the power is turned on, in addition to the door closing restriction process.

  In the door closing restriction process, first, it is confirmed whether the ON signal of the opening detection sensor 53 is detected (S1). If the ON signal is not detected (S1: No), the process of S1 is repeated until the ON signal is detected. .

  When the on signal of the open detection sensor 53 is detected in the process of S1 (S1: Yes), the closing restriction solenoid 52 is turned on (S2), and thereafter the elapsed time after the process of S2 is confirmed (S3). ). If the elapsed time has not reached 5 seconds in the process of S3 (S3: No), the process of S3 is repeated while waiting for progress to the next process, and the elapsed time has reached 5 seconds in the process of S3. If it is confirmed (S3: Yes), the closing restriction solenoid 52 is turned off (S4), and the process proceeds to S1.

  As described above, when the ON signal of the opening detection sensor 53 is detected by the door control board F, the ON of the closing restriction solenoid 52 is performed by the process of continuing the ON state of S3 for 5 seconds after the closing restriction solenoid 52 is turned on. The state continues, and after 5 seconds elapses after the closing restriction solenoid 52 is turned on, the closing restriction solenoid 52 is turned off. As described above, once the front door 51 is opened, the front door 51 cannot be closed unless the closing restriction solenoid 52 is turned on. The front door 51 can be closed only when the front door 51 is closed within 5 seconds after turning on. Therefore, when the front door 51 is slightly opened for the purpose of cheating, the front door 51 is inevitably opened by approximately 90 degrees or more, so that the cheating can be easily detected. The mechanism for restricting the movement of 51 in the closing direction can be performed with electrical control. Note that the object of restricting movement in the closing direction using the closing restriction solenoid 52 and the opening detection sensor 53 is not limited to the front door 51 but may be other members such as the inner frame 3.

  The present invention has been described based on the embodiments. However, the present invention is not limited to the above embodiments, and various modifications can be easily made without departing from the spirit of the present invention. It can be guessed.

  For example, in the first embodiment, as a structure having a ratchet mechanism that restricts movement in the closing direction, one coil spring 14 and a lock to which an urging force as a ratchet mechanism is applied by the coil spring 14. Although the lever 13 is used, the mechanism for restricting the movement toward the closing direction is not limited to the above embodiment. Various known ratchet mechanisms commonly used for seats and the like that regulate the movement in the closing direction in stages and release the restriction in the closing direction only when the opening is larger than a certain amount. May be used.

  You may implement this invention in the pachinko machine etc. of a different type from the said Example. For example, once a big hit, a pachinko machine that raises the expected value of the big hit until a big hit state occurs (for example, two times or three times) including that (for example, a two-time right item, a three-time right item) May also be implemented. Further, it may be implemented as a pachinko machine that enters a special gaming state under the condition that a ball is won in a predetermined area after a big win has occurred. Further, in addition to the pachinko machine, various game machines such as an alepacchi, a sparrow ball, a slot machine, or a game machine in which a so-called pachinko machine and a slot machine are integrated may be used.

  In the slot machine, for example, a symbol is changed by operating a control lever in a state where a symbol effective line is determined by inserting coins, and a symbol is stopped and confirmed by operating a stop button. Is. Therefore, the basic concept of the slot machine is that it is provided with variable display means for confirming and displaying the identification information after variably displaying the identification information string composed of a plurality of identification information, and resulting from the operation of the starting operation means (for example, the operation lever). Then, the change of the identification information is started, and the change of the identification information is stopped due to the operation of the operation means for stop (for example, the stop button) or after the lapse of a predetermined time, and the fixed identification information at the time of the stop Is a slot machine provided with special game state generating means for generating a special game state advantageous to the player on the condition that the specific identification information is a necessary condition. In this case, coins, medals, etc. are representative examples of game media It is given as.

  In addition, as a specific example of a gaming machine in which a pachinko machine and a slot machine are integrated, a variable display means for displaying a symbol after a symbol string composed of a plurality of symbols is displayed, and a handle for launching a ball is provided. What is not provided. In this case, after throwing a predetermined amount of spheres based on a predetermined operation (button operation), for example, the change of the symbol is started due to the operation of the operation lever, for example, due to the operation of the stop button, or With the passage of time, the fluctuation of the symbol is stopped, and a jackpot state advantageous to the player is generated on the condition that the confirmed symbol at the time of stoppage is a so-called jackpot symbol. A lot of balls are paid out.

  The gaming machine of the present invention and its modifications are shown below. In a gaming machine comprising a support member and an open / close member supported by the support member so as to be openable and closable, in a first open state in which the open / close member is opened by a predetermined amount from the closed state, the open / close member is moved toward the closing direction. A game characterized by comprising a closing restriction means for restricting movement and for releasing movement restriction in the closing direction side in the second opened state set with a larger opening amount than the first opened state. Machine 1.

  In the gaming machine 1, the closing restriction means restricts movement of the opening / closing member toward the closing direction by at least two different opening amounts according to the opening amount of the opening / closing member. Game machine 2.

  According to the gaming machine 2, since the movement of the opening / closing member toward the closing direction is restricted by at least two different opening amounts by the closing restricting means, the opening / closing member that has been largely opened is largely opened. Can be regulated. When the clerk inspects and replaces parts related to the game with the opening and closing member opened, the clerk moves in the closing direction with an open amount that can secure the work space of the clerk according to the part layout at the time of design. You may set the opening amount which controls the movement to the closing direction side so that it may control. It is possible to reduce the risk of being accidentally sandwiched between the opening / closing member and the support member during the execution of inspection work or the like.

  In the gaming machine 1 or 2, the closing restricting means is provided on one of the support member or the opening / closing member and swings to the other of the supporting member or the opening / closing member and forming at least one step. An intermediate member having an engaging portion that is supported and engages with the tooth portion in the first open state, and the intermediate member is connected to the engaging portion and the tooth portion in the first open state. And an urging means for urging in a direction in which the engaging portion and the tooth portion are separated in the second opened state, and the engaging portion of the intermediate member includes A gaming machine 3 characterized in that when the opening / closing member is closed from a second open state, the game machine 3 passes through a path separated from the tooth portion.

  According to the gaming machine 3, in the first open state in which the opening / closing member is opened by a predetermined amount from the closed state, the intermediate member is biased toward the tooth portion side by the biasing means. Even if the opening / closing member is to be closed, the engaging portion of the intermediate member is engaged with the tooth portion, and movement of the opening / closing member in the closing direction is restricted. In the second open state in which the opening / closing member is further opened, the intermediate member is biased toward the side away from the tooth portion by the biasing means. The engaging part of the intermediate member can be moved via a path different from that at the time of opening, and the opening / closing member can be closed without engaging the engaging part and the tooth part of the intermediate member. Therefore, it is possible to easily detect an illegal act of opening and closing the opening / closing member by a small amount and to improve the crime prevention property.

  Further, when the urging direction of the engaging portion by the urging means and the tooth portion is switched from the direction in which the two parts approach to each other and the direction in which the intermediate member is engaged is closed from the second open state. The closing of the opening / closing member and the release of the restriction are performed via a path separated from the tooth portion. For this reason, compared with the ratchet mechanism currently used for the conventional seat chair etc., a required number of parts can be reduced and manufacturing cost can be suppressed.

  In the gaming machine 1 or 2, the closing restricting means is movably supported by one of the opening / closing member or the supporting member, and is interposed between the opening / closing member and the supporting member to close the opening / closing member. A restriction position that restricts movement in the direction side, a restriction member that moves from the restriction position to an allowable position where movement restriction between the opening and closing member and the support member is removed, and the restriction member in the first open state. First moving means for moving to a position; second moving means for moving the restricting member to the allowable position; detecting means for detecting whether or not the opening amount of the opening and closing member has reached a predetermined opening amount; When it is detected by the detecting means that the opening amount of the opening / closing member has reached a predetermined opening amount, the second moving means is controlled to move the restricting member to the permissible position and, under certain conditions, the Gaming machine 4, characterized in that a control means to continue the arrangement of the contents position.

  According to the gaming machine 4, in the first open state, the restricting member is moved to the restricting position by the first moving means. Therefore, in the first open state, the movement of the opening / closing member in the closing direction is restricted. Thus, the movement of the opening / closing member toward the closing direction is restricted. When it is detected by the detecting means that the opening amount of the opening / closing member has reached the predetermined opening amount, the second moving means moves the restricting member to the allowable position under the control of the control means, Since the arrangement is continued, the restriction of movement of the opening / closing member in the closing direction is released, and the opening / closing member is closed. Therefore, it is possible to easily detect an illegal act of opening and closing the opening / closing member by a small amount and to improve the crime prevention property.

  In addition, as a constant condition for continuing the arrangement of the restricting member at the allowable position by the control means, the opening degree of the opening / closing member is reached after reaching the predetermined opening amount (or after the predetermined opening amount is reached). The detection means for detecting whether or not a certain period of time elapses or the closed state of the open / close member (including a slightly open state) is in the closed state of the open / close member. Examples of conditions for detection are illustrated. As the first moving means, an elastic body that urges the regulating member toward the regulating position in the first open state and applies an elastic force to interpose the regulating member between the opening / closing member and the support member (for example, The spring in the above embodiment) or the detecting member that detects whether or not the opening / closing member has reached the opening amount in the first open state detects that the opening member is in the first open state. An actuator to be moved (for example, an electromagnetically actuated solenoid) is exemplified.

  In any one of the gaming machines 1 to 4, a lottery is performed based on the establishment of a predetermined condition, and a predetermined game value is given based on the lottery result, and is disposed on the back side of the opening / closing member. A gaming machine 5 comprising the control means. Arranging on the back surface side of the opening / closing member may be disposed on the back surface of the opening / closing member, or may be disposed on the support member.
