Abstract

PROBLEM TO BE SOLVED: To provide an enclosed type game machine for preventing game balls from dropping and being lost when releasing clogging of balls on a game board surface.SOLUTION: A Pachinko machine 1 encloses the prescribed number of game balls, for example, inside a machine and circulates them. A surface frame of the Pachinko machine 1 has a double structure of a front surface frame 30 and a glass door 40. The front surface frame 30 and the glass door 40 are journaled by an upper hinge 24 and a middle hinge of a middle frame 12. When balls are clogged on the board surface of a game board 2, only the front surface frame 30 is opened. Since the glass door 40 remains closed, there is no risk of game balls falling from the board surface of the game board 2. In this state, for example, the glass door 40 is rotated slightly forward. Then, a separation distance between the board surface of the game board 2 and a glass plate 41 of the glass door 40 changes. Since position relations among a plurality of game balls clogged between the glass plate 41 of the glass door 40 and the game board 2 change, clogging of balls is released.

Description

  The present invention relates to an enclosed game machine that encloses and circulates game balls inside a machine.

  2. Description of the Related Art Conventionally, a gaming machine and a gaming apparatus are known in which a game is played by repeatedly firing a game ball enclosed in a gaming machine and driving it into a gaming area of a gaming board (see, for example, Patent Document 1). When a winning area provided in the gaming area is won, a score is given to the player instead of the prize ball. A pachinko machine that is a type of gaming machine includes, for example, an outer frame, a middle frame, and a front frame. The outer frame supports the main body of the pachinko machine. The middle frame is pivotally supported so as to be openable and closable with respect to the outer frame, for example. A game board is detachably fixed to the upper half of the middle frame. The front frame is pivotally supported so as to be openable and closable with respect to the middle frame, for example. A window portion is provided in the approximate center of the table frame. A glass plate is attached to the window. The game board fixed to the upper half of the middle frame is protected by a glass plate attached to the front frame.

  As described above, the front frame and the glass plate are integrated. Therefore, for example, when the operator performs nail adjustment on the game board surface, the table frame may be opened to expose the game board surface. In addition, for example, when a ball clog occurs on the game board surface, an operation of opening the front frame to expose the game board surface and releasing the ball clog may be performed.

JP 2011-104434 A

  However, the enclosed game machine circulates a limited number of game balls in the game machine, so when the table frame is opened and the ball clogging on the game board surface is released, the game ball falls from the game board surface and is lost. There is a risk of doing. If the number of circulating game balls decreases, the number of circulations per unit time of one game ball increases, so that the game ball is likely to become dirty. If you manage the total number of game balls that circulate, it can also cause errors.

  An object of the present invention is to provide an enclosed game machine that can prevent a game ball from falling and being lost when releasing a ball jam on a game board surface.

  An enclosed game machine according to a first aspect of the present invention includes an outer frame, an intermediate frame that is pivotally supported at one end side in the width direction of the outer frame so as to be openable and closable, and holds a game board on a front surface facing the player An enclosed game machine that is pivotally supported at one end in the width direction of the middle frame and includes a front frame that protects the front side of the game board, and encloses and circulates a predetermined number of game balls inside the machine. The front frame has a transparent plate door that holds the first transparent plate on the front side of the game board, and covers the transparent plate door from the front side and presses against the middle frame. A front frame that includes a hole portion that is detachably mounted and faces the first transparent plate held by the transparent plate door, and covers an outer peripheral portion of the front surface of the game board from the front side, and the transparent plate door A first mounting portion for attaching the front frame to the one end side of the middle frame so as to be openable and closable, and the front frame to the one end of the middle frame. And a second mounting portion for mounting to be openable and closable with respect to.

  According to the enclosed game machine according to the first aspect, the front frame has a double structure of the transparent plate door and the front frame. The transparent plate door is attached to the middle frame by a first attachment portion so as to be openable and closable. The front frame is attached to the middle frame by the second attachment part so as to be openable and closable. Therefore, even when the front frame is opened, the transparent plate door is in a closed state. When a clogged ball occurs on the game board surface, the clogged ball is eliminated by opening the front frame and slightly moving the transparent plate door, for example. At this time, it is possible to prevent the game ball from being dropped and lost by opening the work ball so that the game ball does not fall from the game board. In an enclosed game machine, management of a predetermined number of game balls is particularly important, which is effective.

  Further, in the enclosed game machine according to the first aspect, the transparent plate door is provided in the middle frame and biasing means for biasing the transparent plate door in a direction to open forward with respect to the middle frame. It is good to provide the limiting member which prevents opening exceeding a 1st predetermined angle with respect to a middle frame. When the front frame is opened, the first transparent plate is urged forward by the urging means and stopped at the first predetermined angle position by the limiting member. Therefore, since a predetermined gap is generated between the transparent board door and the game board, the position of the game ball jammed between the transparent board door and the game board is changed, so that the clogging can be eliminated. Further, since the transparent plate door does not open beyond the first predetermined angle with respect to the middle frame by the restricting member, for example, it is possible to adjust so that the game ball does not fall from a gap formed between the transparent plate door and the game board.

  Further, in the enclosed game machine according to the first aspect, the first predetermined angle is such that when the transparent plate door is opened with respect to the middle frame, the game ball on the game board is separated from the transparent plate door. The angle should not drop from the gap. By defining the first predetermined angle as described above, it is possible to reliably prevent the game ball from falling from the game board.

  Further, in the enclosed game machine according to the first aspect, the biasing means is an elastic material provided at a peripheral end of the transparent plate door or the middle frame, and pushes the transparent plate door against the middle frame. When the front frame is attached to the middle frame, the elastic material is compressed by being sandwiched between the transparent plate door and the middle frame, and opens the front frame with respect to the middle frame. In this case, the transparent plate door may be urged forward by the elastic restoring force of the elastic material, and may be held in a state where the predetermined angle is opened by the limiting member. By using the elastic restoring force of the elastic material, the transparent plate door can be pushed forward without difficulty. Since the transparent plate door urged forward by the elastic material is stopped by the limiting member, the transparent plate door does not open beyond the first predetermined angle. Further, in a state where the elastic material is urged forward, for example, by hitting the first transparent plate and applying vibration, clogging of the game ball can be effectively eliminated.

  Moreover, in the enclosed game machine according to the first aspect, the restriction member may be a plate-like elastic member and may include a locking portion that locks to the peripheral end portion of the transparent plate door. For example, when the transparent plate door is opened largely to the front side, the locking member is unlocked by bending the limiting member. Therefore, the transparent plate door can be opened beyond the first predetermined angle. Since the front surface of the game board is exposed, for example, inspection work and repair work on the front surface of the game board can be performed.

  In addition, the enclosed game machine according to the second aspect of the present invention includes an outer frame and an inner frame that is pivotally supported at one end in the width direction of the outer frame so as to be openable and closable, and holds the game board on the front surface facing the player. And a front frame that is pivotally supported on one end side in the width direction of the middle frame and protects the front side of the game board, and encloses and circulates a predetermined number of game balls inside the machine The front frame includes a transparent plate door that holds the first transparent plate on the front side of the game board, and covers the transparent plate door from the front side and presses against the middle frame. A front frame that is detachably attached to the frame, includes a hole facing the first transparent plate held by the transparent plate door, and covers the outer periphery of the front surface of the game board from the front side; Third mounting for attaching the plate door to the same side as the one end side of the middle frame among both ends in the width direction of the front frame. When, and a fourth mounting portion for mounting openably said front frame to the one end side in said frame.

  According to the enclosed game machine according to the second aspect, the front frame has a double structure of the transparent plate door and the front frame. The transparent plate door is attached to the front frame by a third attachment portion so as to be openable and closable. The front frame is attached to the middle frame by a fourth attachment part so as to be openable and closable. When the front frame is opened, the transparent plate door is closed and the transparent plate door is slightly separated from the front surface of the game board. Therefore, when a ball jam occurs on the game board surface, the ball jam is eliminated. For example, by adjusting the position of the transparent plate door so that the game ball does not fall from the game board, it is possible to prevent the game ball from dropping and being lost. In an enclosed game machine, management of a predetermined number of game balls is particularly important, which is effective.

  Further, in the enclosed game machine according to the second aspect, when the front frame is opened at a second predetermined angle with respect to the middle frame, and the transparent plate door and the game board are parallel, the transparent plate door And the front surface of the game board is a predetermined distance, and the predetermined distance is determined by the game ball on the game board when the transparent plate door is opened at the predetermined distance with respect to the middle frame. It is good that it is a distance that does not fall from the gap with the transparent plate door. When the front frame is opened at a second predetermined angle, the distance between the transparent plate door and the front of the game board is a predetermined distance when the transparent board door and the game board are parallel. Since the position of the game ball jammed between the transparent board door and the game board is changed by the predetermined distance, the jam can be eliminated. Furthermore, by holding at a predetermined distance, it is possible to prevent the game ball from dropping from a gap generated between the transparent plate door and the game board.

  In the enclosed game machine according to the second aspect, a second transparent plate may be held in the hole. Since the second transparent plate is located on the front side of the first transparent plate, the first transparent plate can be protected. Since it can be protected by the second transparent plate, the first transparent plate can be made thinner and lighter. Since the first transparent plate is thin, it is easy to apply vibration, and thus it is easy to apply vibration to the game ball that is in contact with the first transparent plate. Therefore, clogging of game balls can be easily eliminated.

With respect to the shaft support hole 35A and the shaft support hole 46, the shaft pin 28 of the middle hinge 27 of the middle frame 12 is inserted upward from below. Therefore, the front frame 30 and the glass door 40 can rotate with respect to the middle frame 12. Thereby, for example, when only the front frame 30 is opened, the glass door 40 remains in its position without being rotated.

  Next, the position of the glass door 40 when the front frame 30 is closed will be described. As shown in FIG. 8, when the front frame 30 is closed with respect to the middle frame 12, the glass door 40 is pushed into the middle frame 12 side by the front frame 30. In a state where the front frame 30 is fixed to the middle frame 12 by the cylinder lock, the elastic member 48 of the glass door 40 is pressed against the front surface of the right column portion 12B of the middle frame 12 and compressed. The distance between the board surface of the game board 2 and the back surface of the glass door 40 (the face facing the game board 2) is, for example, A1. In addition, A1 considers the height of structures (for example, the outer rail 3), such as an accessory on the board surface of the game board 2. FIG. For example, it is determined so that the game ball can flow down between the glass board 41 and the board surface of the game board 2 without any trouble. Since the glass door 40 is pushed into the middle frame 12 side, the locking portion 73 of the rotation limiting member 70 and the upper end portion of the glass door 40 are separated from each other. In this state, since the glass door 40 is pushed into the middle frame 12 side by the front frame 30, the glass door 40 can be strongly positioned and fixed.

  Next, a ball clogging release operation when a ball clogging occurs on the board surface of the game board 2 will be described. During the game of the player, a clogged ball may occur on the board surface of the game board 2. When a large number of game balls are concentrated on the structure of the accessory, for example, the game balls ride on the structure. In the state shown in FIG. 8, a plurality of game balls are placed between the glass plate 41 of the glass door 40 and the game board 2. Game balls may get stuck. In this case, the hall operator performs a work to clear the ball clogging. The hall operator inserts a key into the keyhole 21 and turns it clockwise, for example. Then, the fixing of the front frame 30 to the middle frame 12 is released, and the front frame 30 can be rotated. The hall operator rotates the front frame 30 forward. The glass door 40 is pushed forward by the elastic restoring force of the compressed elastic member 48.

  As shown in FIG. 9, the glass door 40 is pushed forward and rotated forward. Since the upper end portion of the glass door 40 is locked to the locking portion 73 of the rotation limiting member 70, the glass door 40 does not rotate further forward. The rotation angle of the glass door 40 at this time is α. The glass door 40 is in contact with the locking portion 73 of the rotation limiting member 70 due to the elastic restoring force of the elastic member 48. The distance between the board surface of the game board 2 and the glass door 40 is A1 to A2. When the rotation angle is α, the separation distance is adjusted to A2. A2 is longer than A1. A2 is a distance at which the game ball does not fall at least between the game board 2 and the glass door 40. Since the distance between the board surface of the game board 2 and the glass door 40 changes from A1 to A2, the positional relationship of the game balls jammed between the glass plate 41 of the glass door 40 and the game board 2 changes. As a result, the ball clogging can be automatically released.

  If the ball clogging still cannot be removed, the ball clogging can be reliably released by, for example, tapping the glass door 40 to apply vibration. Since the separation distance between the board surface of the game board 2 and the glass door 40 is A2, there is no possibility that the game ball falls from the game board 2 and is lost. Thereby, in the enclosed pachinko machine 1, the ball clogging can be released without losing the game balls circulating inside the machine. In addition, the pachinko machine 1 that manages the number of balls does not cause an error due to insufficient number of balls. Furthermore, it is possible to eliminate the tendency of game balls to become dirty due to a decrease in the number of balls.

  For example, when it is necessary to open the glass door 40 to the front side, the upper end portion of the glass door 40 pushes up the locking portion 73 of the rotation limiting member 70. When the locking portion 73 is bent upward, the upper end portion of the glass door 40 gets over the locking portion 73. The rotation limitation of the glass door 40 is released. Therefore, the glass door 40 can be opened beyond the rotation angle α. Since the front surface of the game board 2 is exposed, for example, inspection work and repair work on the front surface of the game board 2 can be performed.

  As described above, the pachinko machine 1 of the present embodiment is an enclosed pachinko machine that encloses and circulates a predetermined number of game balls inside the machine, for example. The pachinko machine 1 includes an outer frame 11, a middle frame 12, a front frame 16, and the like. The front frame 16 has a double structure of the front frame 30 and the glass door 40. The middle frame 12 is pivotally supported with respect to the outer frame 11 by an upper hinge 17 and a lower hinge 30 so as to be opened and closed. The front frame 30 is pivotally supported by the shaft pin 26 of the upper hinge 24 of the middle frame 12 and the shaft pin 28 of the middle hinge 27 so as to be opened and closed. The glass door 40 is also pivotally supported by the shaft pin 26 of the upper hinge 24 of the middle frame 12 and the shaft pin 28 of the middle hinge 27 so as to be opened and closed.

  That is, the front frame 30 and the glass door 40 can be opened and closed independently of each other. Thereby, for example, when ball clogging occurs on the board surface of the game board 2, only the front frame 30 is opened. Since the glass door 40 remains closed, there is no possibility that the game ball will fall from the board surface of the game board 2. In this state, for example, the glass door 40 is slightly rotated forward. In this case, since the separation distance between the board surface of the game board 2 and the glass door 40 changes from A1 to A2, the positional relationship between a plurality of game balls that cause a ball jam between the glass plate 41 and the game board 2 changes. To do. As a result, the ball clogging can be easily released. Thereby, in the enclosed pachinko machine 1, the ball clogging can be released without losing the game balls circulating inside the machine.

  Further, in this embodiment, in particular, the elastic member 48 is provided along the surface on the middle frame 12 side of the right end portion of the glass door 40. The elastic member 48 biases the glass door 40 in a direction to open forward with respect to the middle frame 12. A rotation limiting member 70 is provided on the front surface of the upper column portion 12A of the middle frame 12. The rotation limiting member 70 is locked to the upper end portion of the glass door 40 to prevent the glass door 40 from opening beyond the rotation angle α with respect to the middle frame 12. The rotation angle α may be set so that the game ball on the board surface of the game board 2 does not fall from the gap with the glass door 40. Therefore, there is no possibility that the game ball falls from the game board 2 and is lost.

  The present invention is not limited to the embodiments described in detail above, and various modifications can be made without departing from the scope of the present invention. For example, the following three modifications are possible. The first to third modifications will be described in order.

  A first modification will be described with reference to FIG. In the above embodiment, the glass door 40 is pivotally supported by the shaft pin 26 of the upper hinge 24 of the middle frame 12 and the shaft pin 28 of the middle hinge 27 of the middle frame 12 (see FIG. 2). For example, the glass door 40 may be pivotally supported on the front frame 13 instead of the middle frame 12. The first modification includes a front frame 130. The front frame 130 has substantially the same shape as the front frame 30 (see FIG. 6) of the above embodiment. The shaft support portion 34 of the shaft support end portion 33 includes a shaft support hole 34A and a shaft pin 34B. The shaft support hole 34A extends from the upper part of the shaft support part 34 to the center part. The shaft pin 34 </ b> B extends downward from the lower portion of the shaft support portion 34. The shaft support hole 34A and the shaft pin 34B are coaxial with each other. The shaft support portion 35 of the shaft support end portion 33 includes a shaft support hole 35A and a shaft pin 35B. The shaft support hole 35A extends from the lower part of the shaft support part 35 to the center part. The shaft pin 35B extends upward from the upper portion of the shaft support portion 34. The shaft support hole 35A and the shaft pin 35B are coaxial with each other. Then, the shaft pin 34B and the shaft pin 35B of the front frame 130 are inserted into the shaft support holes 45 and 46 of the shaft support end portion 44 of the glass door 40 of FIG. Thereby, the same effect as the said embodiment can be acquired. Further, the load on the shaft pin 26 of the upper hinge 24 and the shaft pin 28 of the middle hinge 27 of the middle frame 12 can be reduced.

  A second modification will be described with reference to FIG. In the first modification, the axial center of the front frame 130 and the axial center of the glass door 40 are at the same position. For example, the elastic member 48 (see FIG. 7) for biasing the glass door 40 forward can be eliminated by shifting the center of these axes. FIG. 11 shows the behavior of the glass door 240 when the front frame 230 is opened. Note that the middle frame 12, the game board 2, the front frame 230, and the glass door 240 shown in FIG. 11 do not show actual specific shapes, but are simplified to show the positional relationship with each other for convenience. ing.

  The game board 2 is fixed to the middle frame 12. The front frame 230 is pivotally supported so as to be rotatable with respect to the left end side of the middle frame 12. The glass door 240 is pivotally supported so as to be rotatable with respect to the left end side of the front frame 230. The axial center 92 of the glass door 240 is shifted to the free end (right end) side of the glass door 240 with respect to the axial center 91 of the front frame 230.

  STEP 1 is a state where the front frame 230 is closed with respect to the middle frame 12. Similar to the above embodiment, the front frame 230 is fixed to the middle frame 12 with the glass door 240 pressed against the middle frame 12. The distance between the board surface of the game board 2 and the glass plate of the glass door 240 in this state is, for example, B1.

  STEP 2 is a state in which the front frame 230 is opened by 40 ° with respect to the middle frame 12. The glass door 240 does not rotate only by opening the front frame 230. However, as the front frame 230 rotates, the shaft center 92 gradually moves forward. Therefore, the glass door 240 is gradually separated from the board surface of the game board 2. When the glass door 240 and the game board 2 are parallel to each other, the separation distance between the glass door 240 and the glass plate is B2. B2 is longer than B1. B2 is a distance at which the game ball does not fall at least between the game board 2 and the glass door 40. Since the distance between the board surface of the game board 2 and the glass plate of the glass door 40 changes from B1 to B2, the positional relationship of the game balls jammed between the glass plate of the glass door 240 and the game board 2 changes. . Accordingly, for example, if the front frame 230 is opened by 40 ° with respect to the middle frame 12, the ball jam in the game board 2 can be automatically released without losing the game ball.

  STEP 3 is a state in which the front frame 230 is opened 90 degrees with respect to the middle frame 12. At this time, the shaft center 92 is farthest forward from the shaft center 91. Therefore, the glass plate of the glass door 240 is farthest from the board surface of the game board 2. When the glass door 240 and the game board 2 are parallel to each other, the separation distance between the glass door 240 and the glass plate is B3. B3 is longer than B2. For example, B3 may be set to a distance at which game balls do not fall at least between the game board 2 and the glass door 40. For example, in order to make the glass door 240 and the game board 2 parallel to each other, a rotation limiting member 95 may be provided on the middle frame 12. The rotation restricting member 95 is, for example, engaged with the front surface of the glass door 240 when the front frame 230 is opened 90 ° with respect to the middle frame 12 and the glass door 240 is parallel to the game board 2. Thereby, irrespective of the rotation angle of the front frame 230, the separation distance with the glass plate of the glass door 240 does not exceed B3. The hall operator can automatically release the clogged balls in the game board 2 without worrying about the rotation angle of the front frame 230.

  A third modification will be described with reference to FIG. In the above embodiment, the front frame 16 holds one glass plate 41. The glass plate 41 is held by a glass door 40. The pachinko machine 300 of the third modification holds two glass plates. A glass plate 141 is attached to the back side of the front frame 30. Therefore, the front side of the game board 2 is protected by the glass plate 41 of the glass door 40 and the glass plate 141 attached to the front frame 30. Since the glass plate 141 is located on the front side of the glass plate 41, the glass plate 41 can be protected. Since the game board 2 can be protected by the two glass plates 41 and 141, for example, the glass plate 41 can be made thinner and lighter. Since the glass plate 41 becomes thin, it becomes easy to apply vibrations, and therefore it becomes easy to apply vibrations to the game ball that contacts the glass plate 41. Therefore, clogging of game balls can be easily eliminated.

  The present invention can be modified in various ways other than the above modification. For example, the present invention can be applied to a ball game machine such as a sealed ball game machine and a sparrow ball game machine in addition to a sealed pachinko machine.

  Moreover, in the said embodiment, although the glass door 40 hold | maintains the glass plate 41, a transparent resin member may be sufficient instead of the glass plate 41, for example. Further, as long as it is transparent, the material, shape, color, etc. are not limited.

  Moreover, in the said embodiment, although the operation unit 15 is provided as the enclosed pachinko machine 1, the shape, structure, etc. of the operation unit 15 are not limited to the said embodiment. Further, the launch handle 14 for launching the game ball may be other than the handle type (for example, button type, touch type, etc.).

  Moreover, in the said embodiment, each name of the outer frame 11, the inner frame 12, the front frame 16, the front frame 30, and the glass door 40 is for convenience of explanation, and naturally it is used also for what is used by names other than these. It is applicable to.

  Moreover, in the said embodiment, in order to restrict | limit the movement to the front of the glass door 40, although the rotation limitation member 70 is provided in the front upper part of the middle frame 12, the position of the rotation limitation member 70 is not limited to this. . For example, the rotation limiting member 70 can be provided at the free end and the lower end of the middle frame 12. Furthermore, the shape of the rotation restricting member 70 is not limited to this, and for example, it may be provided with a protruding portion that is locked to the glass door 40.

  Moreover, in the said embodiment, although the outer frame 11 and the inner frame 12 are separate bodies, it may provide as an integral base frame and may attach a table frame with respect to a base frame so that opening and closing is possible.

  Moreover, in the said embodiment, although the elastic member 48 attached to the glass door 40 is provided long along the right end part of the holding frame 42, you may provide in a part or several part, for example. The shape is not limited.
