Abstract

PROBLEM TO BE SOLVED: To provide a Pachinko machine in which the expansion or contraction and the distortion of a game board caused by the heat of a symbol display device can be suppressed.SOLUTION: A heat radiating member 34 is installed in a state where a part (conductive part 34a and a flange 36) thereof is brought into contact with a liquid-crystal display 30 while a heat radiation part 34b projects forward of a game board 2 via a ventilating window 29. Therefore, the heat generated from the liquid-crystal display 30 is transmitted from the conductive part 34a and the flange 36 to the heat radiation part 34b, and then radiated to the front of the game board 2. Accordingly, a temperature rise at the rear of the game board 2 caused by the heat of the liquid-crystal display 30 can be suppressed, and especially, the deformation (amount of expansion and contraction) generated at the rear of the game board 2 can be minimized.

Description

  The present invention relates to a pachinko machine.

  In recent years, a pachinko machine in which a game board is formed of a transparent synthetic resin has been devised in order to improve game playability (for example, Patent Document 1). In such a pachinko machine, a liquid crystal display device for displaying a “symbol” (for example, a so-called “demo symbol”) related to the jackpot lottery is installed at the back of the game board as well as a conventionally known pachinko machine. Has been.

JP 2005-152580 A

However, game boards molded from synthetic resin are easily affected by changes in ambient temperature, and the surface (rear surface) expands due to the heat of the liquid crystal display device, and as a result, game nails are implanted in the game area. There is a possibility that a problem may occur that, for example, a game ball cannot win a tulip-type electric accessory because the interval between them changes greatly. In addition, due to a temperature difference between the front and rear of the game board, the thermal expansion coefficient differs between the front and rear faces of the game board, and the entire game board warps forward or backward.
Furthermore, in solving the above problems, it may be possible to adopt a synthetic resin that is not easily affected by heat, that is, not easily deformed by heat. However, such a synthetic resin is relatively expensive and has poor workability, so that a game board is manufactured. There are also problems such as being unsuitable for.

  Therefore, the present invention has been made in view of the above problems, and an attempt is made to provide a pachinko machine that can suppress the expansion or contraction or distortion of the game board due to the heat of the symbol display device without using an expensive synthetic resin. To do.

  In order to achieve the above object, the invention according to claim 1 of the present invention is characterized in that a game board made of a synthetic resin plate-like member having a game area in which a game ball flows down is provided on the front surface, A pachinko machine having a ramp member installed in an area, wherein an opening that penetrates from the front surface to the rear surface of the gaming board is opened, the surface area of the gaming board is increased, and the opening is covered by the ramp member. Features.

  In the pachinko machine in which a game board made of a synthetic resin plate-like member in which a game area where a game ball flows down is installed on the front surface, an opening that penetrates from the front surface to the rear surface is opened in the game board, A configuration is also conceivable in which the surface area of the game board is increased, and at least a part of the front of the opening is covered with a game member located in the game area. And if this structure is employ | adopted, since the opening penetrated from the front surface to the back surface is opened in the game board, the surface area of a game board will increase. Therefore, the heat transmitted to the game board can be released particularly from the cross section of the opening, and the expansion of the game board can be suppressed. Further, by providing the opening, the expansion or contraction can be escaped inward from the outer peripheral edge of the game board. Therefore, the deformation amount (expansion amount or contraction amount) in the entire game board can be reduced. Furthermore, since the front of the opening is covered with a gaming member at least partially located in the gaming area, the design when viewed from the front is not impaired.

In addition, in a pachinko machine in which a synthetic resin game board having a game area in which a game ball flows down is installed and a symbol display device is installed behind the game board, An opening that penetrates from the back to the rear surface is opened, while a part is in contact with the symbol display device, and a heat radiating member that exposes the heat radiating portion from the opening is provided, so that heat generated from the symbol display device is partially mediated Therefore, a configuration that enables heat dissipation is also conceivable. And if this structure is employ | adopted, the heat which generate | occur | produced from the symbol display apparatus with the heat radiating member can be escaped from the opening to the front of a game board, without staying behind.
Further, a pachinko machine in which a game board made of a synthetic resin with a game area in which a game ball flows down is installed on the front, and a symbol display device is installed behind the game board, part of which is a symbol A structure is also conceivable in which a heat radiating member is provided in contact with the display device, and the heat radiating portion protrudes outward from the game board, so that heat generated from the symbol display device can be radiated from the part through the heat radiating portion. . And if this structure is employ | adopted, heat can be released to the upper direction of a game board, a side, etc. Therefore, without using an expensive synthetic resin, it is possible to suppress the temperature rise behind the game board due to the heat of the symbol display device, and in particular, it is possible to reduce the expansion or contraction that occurs on the rear surface of the game board.

Furthermore, the structure which makes a thermal radiation part protrude ahead rather than the front surface of a game board is also considered. And if this structure is adopted, since the heat radiating part protrudes to the front of the game board, the heat generated from the symbol display device can be released to the front of the game board, resulting in a gap between the front and rear of the game board. The temperature difference that occurs in can be kept small. Therefore, it is possible to prevent the occurrence of a situation such as a difference in the amount of expansion or contraction between the front surface and the rear surface of the game board and the warping of the game board.
Furthermore, a configuration is also conceivable in which the front of the heat radiating portion is covered with a gaming member at least part of which is located in the gaming area, and a vent hole is formed in the gaming member. And if this configuration is adopted, the design of the pachinko machine is impaired even if the opening is provided in the game area because at least a part of the heat radiating portion is covered with a game member located in the game area. There is no. In addition, since the game member is provided with a vent hole, the heat released from the heat radiating portion can be released without accumulating.
In addition, a configuration in which an arc-shaped slit along the circumference centering on the center of the game board is provided on the game board is also conceivable. And, when this configuration is adopted, since the game board is provided with a slit, even if expansion or contraction occurs, the slit can escape the expansion or contraction inward from the outer peripheral edge of the game board, The amount of deformation in the entire game board can be reduced. In addition, since the slit is formed in an arc shape along the circumference centered on the center of the game board, expansion or contraction can be easily released in the slit, and the situation where the game board is bent more effectively Can be suppressed.

  According to the present invention, since the opening penetrating from the front surface to the rear surface is opened in the game board, the surface area of the game board is increased. Therefore, the heat transmitted to the game board can be released particularly from the cross section of the opening, and the expansion of the game board can be suppressed. Further, by providing the opening, the expansion or contraction can be escaped inward from the outer peripheral edge of the game board. Therefore, the deformation amount (expansion amount or contraction amount) in the entire game board can be reduced. Furthermore, since the opening is covered with the lamp member, the design when viewed from the front is not impaired.

In addition, a large opening 43 is formed at the front side central portion of the base member 42, and the peripheral edge of the large opening 43, that is, the inner peripheral edge of the frame member, is one step behind the outer peripheral edge of the frame member. A recessed support recess 44 is provided, which can be supported by fitting the flat plate member 41 into the support recess 44 of the base member 42 in the assembled state. It should be noted that the front surface of the support recess 44 is in contact with the rear surface of the outer portion further than the large-diameter slits 27A and 27B, the small-diameter slits 28A and 28B, and the ventilation window 29 of the flat plate member 41 (that is, in the fitted state, the flat plate member). 41, the large-diameter slits 27A and 27B, the small-diameter slits 28A and 28B, and the ventilation window 29 are positioned in the large opening 43).

The liquid crystal display device 30 is installed behind the game board 2 in which the flat plate member 41 and the base member 42 are assembled. FIG. 6 is a perspective explanatory view showing the liquid crystal display device 30, and FIG. 7 is an explanatory view showing the mounting bracket 33, where (a) is the front side, (b) is the right side surface, and (c) is the side view. The upper surface is shown respectively.
The liquid crystal display device 30 is formed by attaching a metal frame member 32 so as to cover the periphery and the rear surface of a substantially rectangular display screen 31 displaying “symbol” or the like, and via a mounting bracket 33 shown in FIG. The display screen 31 is screwed to the middle frame 5 or the like so as to be positioned behind the symbol display unit 6. The mounting bracket 33 is a box-shaped body whose front and lower surfaces are open, and the liquid crystal display device is configured such that the inner surfaces of the upper surface, the left and right side surfaces, and the rear surface are in contact with the upper surface, left and right side surfaces, and the rear surface of the frame member 32, respectively. It is attached to the upper part of 30. Reference numeral 33 a denotes a screwing portion for screwing the mounting bracket 33 to the upper surface of the liquid crystal display device 30.

  Further, the heat radiating member 33 shown in FIG. The heat radiating member 34 is a metal plate member bent in a substantially L shape, and includes a conductive portion 34a extending forward from the upper surface of the mounting bracket 33, and heat dissipation caused by bending upward in front of the conductive portion 34a. Part 34b. A screw hole 35 for screwing the heat radiating member 34 to the screwing portion 33a of the mounting bracket 33 is provided at the rear end of the conductive portion 34a, and the frame member 32 is screwed to the mounting bracket 33. A flange piece 36 that is in contact with the front surface of the head is projected downward. On the other hand, a plurality of heat radiation fins 37, 37,. Further, the heat radiating portion 34b is sized so as to be able to be inserted through the ventilation window 29, and to the front of the game board 2 through the ventilation window 29 as the liquid crystal display device 30 is installed behind the game board 2. It is designed to protrude.

Here, the operation and effect relating to the installation of the game board 2 and the liquid crystal display device 30, the heat radiation generated by the liquid crystal display device 30, and the distortion suppression of the game board 2 by the large-diameter slit 27A and the like will be described.
First, the flat plate member 41 is fitted into the support recess 44 of the base member 42 to assemble the game board 2. Next, from the front of the game board 2, the game nail, the scissor member 14, the ramp member 15, the gate member 16, the tulip-type electric accessory 17, the big winning device 18, the winning member 19 and the like are assembled. By assembling the various members, the large mounting hole 22, the lamp hole 23, the winning hole 24, the installation hole 26, the large diameter slits 27A and 27B, the small diameter slits 28A and 28B, and the ventilation window 29 are all moved forward by the assembled members. Will be covered. And the game board 2 which assembled | attached all the members is installed in the middle frame 5. FIG.

Next, the mounting bracket 33 is attached to the liquid crystal display device 30, and the heat radiating member 34 is screwed to the upper surface of the mounting bracket 33 so that the heat radiating portion 34b protrudes forward. At this time, the heat radiating member 34 is in a state where the end of the conductive portion 34 a and the flange piece 36 are in contact with the liquid crystal display device 30. Then, the liquid crystal display device 30 with the heat dissipation member 34 attached in such a posture is installed at a predetermined position behind the game board 2. In the installed state of the liquid crystal display device 30, as shown in FIG. 9, the heat radiating portion 34 b of the heat radiating member 34 protrudes to the front of the game board 2 through the ventilation window 29 and is located in the bulging portion of the gutter member 14. Yes.
In this way, the game board 2 and the liquid crystal display device 30 are assembled and installed.

  In the pachinko machine 1 having the game board 2 and the liquid crystal display device 30 as described above, the liquid crystal display device 30 operates when the power is turned on, and heat is generated in the liquid crystal display device 30. However, this heat is transmitted from the frame member 32 to the conductive portion 34a of the heat radiating member 34 via the mounting bracket 33 (or directly transmitted from the frame member 32 to the flange piece 36), and further transferred to the front heat radiating portion 34b, and then radiated. The heat is dissipated through the fins 37, 37,. Further, the heat released from the heat radiating fins 37 escapes further to the front of the game board 2 through the ventilation slits 14a, 14a. Therefore, the temperature rise behind the game board 2 due to the heat of the liquid crystal display device 30 can be suppressed without using an expensive synthetic resin that is not easily deformed by heat, and in particular, the amount of deformation generated on the rear surface of the game board 2 (Expansion or contraction amount) can be kept small. In addition, since the temperature rise behind the game board 2 can be suppressed, it is possible to prevent a situation in which a large temperature difference occurs between the front surface and the rear surface of the game board 2 and the amount of expansion or contraction caused by the temperature difference. It is also possible to prevent the occurrence of a situation such as the game board 2 warping greatly due to the difference.

  Further, it is difficult to completely suppress the expansion or contraction of the game board 2, resulting from the heat generated by the main controller 20 as well as the liquid crystal display device 30, the friction of the game ball flowing down the game area 2 a, and the like. The front surface and the rear surface of the game board 2 (particularly the flat plate member 41) tend to thermally expand or contract. However, in the game board 2, since the large-diameter slits 27A and 27B and the small-diameter slits 28A and 28B are provided in the flat plate member 41 on which game nails and the like are installed, the inner side of the outer peripheral edge of the game board 2 by the respective slits. In this way, expansion or contraction can be released. Therefore, the amount of deformation in the entire game board 2 can be reduced. Furthermore, since each slit is formed in an arc shape, expansion or contraction can be easily released in each slit, and a situation in which the game board 2 is bent can be more effectively suppressed. In addition, the surface area of the flat plate member 41 is increased by providing the large-diameter slits 27A and 27B, the small-diameter slits 28A and 28B, and the ventilation window 29. Therefore, the heat transmitted to the game board 2 is released particularly from the cross sections of the slits and the ventilation windows 29, and the expansion of the game board 2 is further suppressed.

  On the other hand, it is difficult to completely eliminate the temperature difference between the front and rear of the game board 2, and various control devices such as the main control device 20 are installed in addition to the liquid crystal display device 30. The rear side of the door tends to be hotter than the front side. However, in the pachinko machine 1, in addition to the installation of the heat radiating member 34, the air vent 29 is formed in the flat plate member 41, so that air spontaneously flows between the front and rear of the game board 2, and the temperature difference is Will be reduced. Therefore, a difference in deformation amount hardly occurs between the front surface and the rear surface of the game board 2, and thus warpage generated in the game board 2 can be further reduced.

Further, the large-diameter slits 27A and 27B, the small-diameter slits 28A and 28B, and the ventilation window 29 are covered with the flange member 14, the lamp member 15, and the winning member 19, so that the design when viewed from the front is impaired. There is nothing.
Furthermore, since the game board 2 is composed of a flat plate member 41 and a base member 42 that supports the flat plate member 41, and a lattice structure is formed on the rear surface of the base member 42, the base member 42 is originally heated. Even if the flat plate member 41 is expanded or contracted, the expansion or contraction is not easily transmitted to the base member 42. Therefore, it is possible to prevent a situation in which even the base member 42 expands or contracts, and a load is generated at a portion where the game board 2 is installed on the middle frame 5, and the deformation amount and distortion of the game board 2 as a whole. The amount can be suppressed.

  The configuration related to the pachinko machine of the present invention is not limited to the aspect of the above embodiment, and the configuration related to the game board and the heat dissipation mechanism is within the scope of the present invention as necessary. It can be changed as appropriate.

For example, a vent hole may be formed in the conductive portion 34a or the heat radiating portion 34b of the heat radiating member 34. By adopting this configuration, air can flow more smoothly between the front and rear of the game board 2, and the temperature difference between the front and rear can be eliminated.
Further, the heat radiating part 34b of the heat radiating member 34 does not necessarily have to protrude forward through the ventilation window 29, and the heat radiation part 34b is easily accumulated in the ventilation window 29 in a front view and tends to accumulate behind the game board 2. You can expect the effect of releasing heat. Furthermore, even if the heat radiating part 34b is exposed to the upper side or the side of the game board 2, it is possible to release heat, and the ventilation window 29 may not be provided.

  Furthermore, the heat radiating member is not limited to that of the above embodiment, and for example, a configuration as shown in FIG. 10 may be adopted. FIG. 10 is an explanatory view showing a modified example of the heat radiating mechanism portion, in which a heat radiating member 50 including a conductive portion 50a and a heat radiating portion 50b is provided integrally with the heel member 14 behind the heel member 14. Yes. The flange member 14 (including the heat radiating member 50) is formed of a synthetic resin having high thermal conductivity (for example, polylactic acid resin to which carbon fiber is added). Radiation fins 50c (made of synthetic resin) are provided so as to project. This saddle member 14 is attached from the front of the game board 2 through the ventilation window 29 so that the heat radiating member 50 protrudes rearward, and the conductive portion 50a of the heat radiating member 50 protruding rearward is connected to the liquid crystal display device 30. Thus, the heat generated from the liquid crystal display device 30 can be radiated to the front of the game board 2 via the heat radiating member 50 and the gutter member 14. By integrally forming the flange member 14 and the heat radiating member 50 in this way, the heat radiating member 50 is positioned only by attaching the heel member 14, so that there is an advantage that installation work is facilitated. The mounting member (mounting bracket 33) can also be made of a synthetic resin having high thermal conductivity, and a heat radiating member or mounting formed by metal plating on the surface of the synthetic resin that is not so high in thermal conductivity. Of course, it is also possible to employ members. Needless to say, the heat dissipating member may be integrally formed with other game members such as a lamp member instead of the collar member, and it is not always necessary to provide heat dissipating fins in the heat dissipating portion of the heat dissipating member.

In addition, air holes such as the ventilation slits 14a are formed in the slits 15A and the winning member 19 covering the slits such as the large-diameter slit 27A and the small-diameter slit 28A, the lamp hole 23 and the winning hole 24, etc. When the member 15 or the winning member 19 is installed on the front surface of the flat plate member 41, the air can also flow through a slit, a lamp hole, or the like by slightly floating from the surface of the flat plate member 41. .
Further, the shape of the ventilation slit 14a in the collar member 14 as well as the formation position and the like can be naturally changed in design, and may be provided on the upper surface and the lower surface of the collar member 14. By providing the ventilation slits 14a on the upper surface and the lower surface of the heel member 14 in this way, when a player or the like looks from the front, the heat radiating member inside the heel member 14 cannot be seen, and the pachinko machine having excellent design characteristics can do. In particular, by providing the ventilation slit 14a on the upper surface of the flange member 14, the air that is heated and moves upward can be released as it is, and effects such as heat dissipation and elimination of the temperature difference can be expected. In addition, the large-diameter slit 27A, the small-diameter slit 28A, etc. are not necessarily formed in an arc shape, and may be linear.
