Description

  The present invention relates to a gaming machine.

  In a gaming machine such as a pachinko machine, an inner frame is assembled to a rectangular outer frame so as to be opened and closed, and a front frame is provided on the inner frame so as to be opened and closed. A game board is detachably attached to the front side of the inner frame visible from the player.

  When assembling the game board to the inner frame, a game board fixing device has been proposed in which the front position of the game board is always maintained at a fixed position and the game board is fixed to the mounting frame regardless of variations in the thickness of the game board.

  Specifically, an elastic member (plate spring) that presses the game board forward is provided on the back plate, the clamp lever is positioned vertically by a clamp that presses the game board backward, and the game board is held back and forth. The variation in thickness is absorbed by the elastic member (see Patent Document 1).

Alternatively, a first pressing member (leaf spring) that presses the game board to the right side in the housing frame (corresponding to the inner frame) is provided at two locations on the left side, and the game board is pressed toward the front side. Four second pressing members (plate springs) are provided on the top, bottom, left, and right of the back surface, and the game board is moved up and down by pressing toward the latch member that regulates the front position of the game board fixed to the storage frame. A game board fixing device for positioning in the left-right direction and the front-back direction has also been proposed (see Patent Document 2).
JP 2006-130214 A JP 2008-161720 A

In the game board fixing device described above, the game board is urged by a leaf spring bent from the rear to the front with respect to the frame body (inner frame), and the front side is abutted. The leaf springs provided at a plurality of locations on the back side of the body may be assembled while the game board is tilted due to variations in the urging force due to variations in elastic force due to differences in solids or due to elastic fatigue.
In addition, since the elastic body, which is a metal material, is in direct contact with the rear surface of the game board and urges it, when the game board is attached to or detached from the inner frame, it rubs against a game board made of a veneer board or a resin board. As a result, there is a risk of dents due to damage and stress concentration, which reduces the accuracy of the game board assembly.
Furthermore, when the game board is pressed with reference to the front surface, the continuity of the game area is lost due to variations in the assembly accuracy of the game board, so that the performance and reliability of the gaming machine also deteriorates.

  An object of the present invention is to provide a gaming machine that solves the above-described problems of the prior art and improves the accuracy of assembly with respect to the inner frame of the gaming board.

In order to achieve the above object, the present invention comprises the following configuration.
A gaming machine in which a game board is held by a game board holding part formed in an inner frame, provided integrally with the game board holding part, and a reference part for defining a reference position in the front-rear direction of the game board; A game board urging means that is provided in the game board holding part and urges the game board to constantly press the game board against the reference part, and the game board is provided on an urging side of the game board urging means; A movable body that operates by contact is provided, and the game board held by the game board holding portion is pressed against the reference portion while being in contact with the movable body biased by the game board biasing means. It can be assembled.

  The game board holding unit includes a pair of vertical frames that hold the left and right direction of the game board, a pair of horizontal frames that hold the vertical direction of the game board, and a game board receiving part that receives the rear side of the game board. The game board receiving part is formed with an attachment part in which the game board urging means and the movable body are provided, and the movable body is urged by the game board urging means. Further, the game board receiving portion protrudes forward and is supported.

  Further, the one vertical frame is integrally provided with a reference portion formed with a reference surface for abutting the front surface of the game board, and the other vertical frame holds the game board in the game board holding portion. A game board fastener is assembled, and when the game board is held by the game board holding part, the front side of the game board is kept pressed by the movable body urged by the game board urging means. The game board is assembled on the basis of the front surface by abutting against the reference surface of the reference portion and the game board fastener.

  The attachment portion is formed separately from the inner frame, and is detachably attached to the inner frame.

  The movable body is a rotating body that rolls in contact with the game board.

If the above-described gaming machine is used, the gaming board held by the gaming board holding portion is assembled by being pressed against the reference portion while being in contact with the movable body biased by the gaming board biasing means. It is possible to reduce problems such as torsion and distortion of the game board urging means due to friction or direct collision caused by direct contact between the game board and the game board urging means. Further, when the game board is attached or detached, the game board is not rubbed and damaged by the game board urging means, or dents are not generated due to stress concentration, and the game board can be protected.
Therefore, the assembly accuracy of the game board held by the game board holding part can be maintained.

Also, an attachment part is provided in which a game board urging means and a movable body are provided, and the movable body is urged by the game board urging means and is supported by protruding from the attachment part to the front of the game board receiving part. Therefore, when the game board is attached to or detached from the game board holding part, it does not interfere with other parts, and only the movable body can be brought into contact with the game board and reliably pressed toward the reference part.
In addition, since the movable body is always urged by the game board urging means and protrudes from the storage part to the front of the game board receiving part, the movable body is in contact with the rear surface of the game board when the game board is assembled. Once the game board is pushed back to the storage part and is assembled to the game board holding part, a guide is provided. When the game board is assembled to the game board holding part, the game board is biased forward and positioned. Thus, since the movable body plays an auxiliary role in the game board assembling work, the assembling work of the game board becomes easy.

Moreover, since the reference | standard part is formed in one vertical frame of the game board holding | maintenance part, it can integrally mold with an inner frame and can reduce a number of parts. In addition, since the game board fastener assembled to the other vertical frame is also used as the reference part, the game board is kept while the rear surface of the game board is pressed by the movable body urged by the game board urging means in the game board holding part. The front face is abutted against the reference portion and the game board fastener, respectively, so that the game board can be reliably positioned and held with respect to the front face.
Note that it is preferable that the game board urging means is provided in the vicinity of the four corners of the game board held by the game board holding part in order to urge the game board toward the front in a balanced manner. Further, the game board urging means is provided in the peripheral part of the reference part and the game board fastener, so that the reference position of the game board is reliably determined.

  Also, if the attachment part is formed separately from the inner frame and is detachably assembled to the inner frame, the movable body and the game board urging means may deteriorate over time due to continued use of the gaming machine. Since the unit can be replaced, the replacement work becomes easy.

In addition, by using a rotating body as the movable body, the burden on the abutment portion of the game board is eased when the game board is attached and detached, and the movable body is attached by friction and collision between the game board and the movable body generated when the game board is assembled. Problems such as twisting and distortion of the biasing means can be further reduced.
In addition, it is desirable that the outer peripheral surface of the rotating body, such as a cylinder, a column, a torus, or a sphere, is formed into a curved surface, which can reduce the load on the game board urging means when the game board is assembled. The durability of the machine can also be improved.

  Next, the game board fastener 12 is assembled to the attachment portion 15 from the front of the insertion hole 18. Specifically, in FIG. 7C, the game board fastener 12 is assembled to the attachment portion 15 from the front of the insertion hole 18. Specifically, the pedestal portion 12c provided at the shaft end of the rotating shaft 12b is inserted into the first opening 15a with the pedestal portion 12c at the head, and the projection portion 14e is pushed down by the pedestal portion 12c to bend the locking portion 14d. insert. (See FIG. 7 (e)). Next, as shown in FIG. 7D, the pedestal 12c is slid so that the rotating shaft 12b is fitted into the second opening 15b. At this time, since the pedestal part 12c holding the projection part 14e is released, the locking part 14d is elastically restored and the projection part 14e comes into contact with the end surface of the pedestal part 12c (see FIG. 7F). Further, the fastening portion 12 a is supported by a support portion 15 d provided on the front surface of the attachment portion 15.

As described above, in the game board fastener 12, the pedestal portion 12c is sandwiched between the attachment portion 15 and the base surface portion 14b in the axial direction and is prevented from being detached, and the protrusion 14e at the distal end of the locking portion 14d and the second opening 15b. The wall surface is assembled so as to be rotatable while the radial movement of the rotary shaft 12b is restricted.
Thus, since the game board fastener 12 and the game board 6 can be assembled to the inner frame 3 from the front side without using a fastener such as a screw, the game board fastener 12 is provided. The assembling work for the inner frame 3 can be simplified and the maintenance work can be easily performed.

  Further, when the game board fastener 12 is removed from the attachment portion 15, the game board fastener 12 is moved to the locking position (see FIG. 8B) with the game board 6 not in the game board holding portion H. The game board fastener 12 is moved from the second opening 15b to the first opening 15a while the locking part 14d is visible in a front view and the locking part 14d is bent. Thereafter, the game board fastener 12 can be removed by moving the game board fastener 12 to the front side of the first opening 15a (the side opposite to the locking portion 14d).

  8 (a) and 8 (b), the plate 13 assembled to the game board 6 is provided with positioning parts 13b and 13c for positioning the fastening part 12a of the game board fastener 12 in the locking position. Yes.

  Further, the protrusions 12d and 12d that can be locked to the support portion 15d or the positioning portion 13b and the protrusions that can be locked to the positioning portion 13c are provided on the back surface (opposite surface of the plate 13) of the fastening portion 12a of the game board fastener 12. Each of the strips 12e and 12e is projected.

  Further, in FIG. 8B, when the game board fastener 12 is in the locking position, the ridges 12d and 12d are on both sides of the positioning portion 13b, and the ridges 12e and 12e are on both sides of the positioning portion 13c. The game board fastener 12 is restricted from freely rotating. Since the protrusions 12d and 12d and the protrusions 12e and 12e are formed on the fastening portion 12a, the game board fastener 12 can be reliably prevented from rotating at both the retracted position and the locking position. It is possible to prevent problems such as rattling caused by holding 6 at a halfway position. Further, even if the game board fastener 12 is replaced, if the positions of the protrusions 12d and 12d and the protrusions 12e and 12e are made common, the rotation can be similarly prevented.

Further, FIGS. 9A and 9B show another configuration for preventing the game board fastener 12 from rotating.
9A and 9B, the plate 13 is formed with a stopper portion 17 that prevents the game board fastener 12 in the locking position from sliding from the second opening portion 15b toward the first opening portion 15a.

In this case, when the game board fastener 12 is in the locking position, the protrusion 12f abuts against the stopper portion 17 so that the rotary shaft 12b moves from the second opening portion 15b toward the first opening portion 15a. It is preventing. Further, in FIG. 9B, it is desirable that the protrusion 12f and the stopper portion 17 are vertically projected from the facing portion 12a and the facing surface of the plate 13 where the game board fastener 12 and the plate 13 face each other. . As a result, when the game board fastener 12 is in the locking position, the protrusion 12f may get over the stopper portion 17 even if a force is applied to move from the second opening 15b to the first opening 15a. This is not possible, and the retaining position of the game board 6 can be reliably held.

  Therefore, for example, by intentionally bending the locking portion 14d from the outside, even if the locking between the projection 14e and the pedestal portion 12c is temporarily released, the protrusion 12f and the stopper portion 17 are locked, so the gaming board An illegal act of sliding the fastener 12 from the locking position can be prevented.

  Next, another example of the attachment portion 15 of the game board fastener 12 is shown in FIGS. In the embodiment described above, the base body 14 is configured separately from the inner frame 3, but may be integrally formed in the insertion hole 18 formed in the attachment portion 15. In FIG. 10A, the configuration of the game board fastener 12 is the same as that of FIG.

10B, a locking portion 15f (locking means) is integrally formed in a cantilever shape in an insertion hole 18 provided in the mounting portion 15. The locking portion 15f is provided so as to be elastically deformable by forming a slit 15e on a bottom plate protruding corresponding to the first opening 15a and the second opening 15b continuous therewith. A protruding portion 15g is formed at a predetermined position of the locking portion 15f, and the protruding portion 15g is locked to the outer peripheral surface of the pedestal portion 12c with the rotating shaft 12b fitted into the second opening 15b. To be provided. Further, a bearing portion 15h is formed on the distal end side of the protrusion portion 15g of the locking portion 15f. The bearing portion 15h supports the rear surface side of the pedestal portion 12c when the assembly of the game board fastener 12 is completed.
According to the above configuration, when the inner frame 3 is molded, the mounting portion 15 having the locking portion 15e in the insertion hole 18 is also integrally molded, so that the number of parts is small and the assembly process can be simplified.

Here, when assembling the game board 6 to the game board holding portion H of the inner frame 3, a structure assembled on the basis of the front surface will be described with reference to FIGS. 3 and 11 to 13. FIG.

When the claw portion 3g of the locking hook 3f is locked to the locking groove 20i by elastically returning to both sides, the mounting hole 24 is prevented from coming off in the front-rear direction and assembled.

When the movable body 19 and the coil spring 23 deteriorate with time due to continuous use of the pachinko machine 1 and these parts are to be replaced, the side walls 20h of the case body 20d are deformed so as to be close to each other and the locking grooves 20i The case main body 20d can be removed from the inner frame by being pulled out to the back side of the insertion hole 24 with the locking hook 3f being unlocked from the claw portion 3g, and the entire unit can be replaced. Thereby, the exchange work of the movable body 19 and the coil spring 23 becomes easy.
In the above embodiment, the case body 20d is elastically deformed and detachably assembled to the inner frame 3. However, the locking hook 3f may be elastically deformed and detachably assembled.
In the above embodiment, the case main body 20d and the locking hook 3f are locked and the attaching portion 20A is fixed to the inner frame 3. However, the case body 20d is fixed to the inner frame 3 by a fastening member such as a screw. It may be.

In each of the above-described embodiments, the movable body 19 is supported so as to be rotatable about the rotation shaft 22c supported by the movable body receiving portion 22, but the rotation shaft 22c is supported by the inner frame 3 (for example, the lower horizontal frame 3c and the lower horizontal frame 3c). It may be supported so as to be movable in the longitudinal direction in a groove or rail provided in the upper horizontal frame 3d). In this case, it is preferable that the game board urging means P urges the rotating shaft 22c toward the front side of the inner frame in the groove or rail, for example.
