Description

  The present invention relates to a pachinko machine, and more particularly, to a pachinko machine equipped with a control base that generates heat.

  Current pachinko machines are equipped with a liquid crystal display panel on which various images such as reach action images are displayed in order to improve interest. In order to control the image displayed on the display panel, a control board called a display sub board is provided on the back of the pachinko machine. In recent pachinko machines, the display sub-base is often equipped with a CPU that can perform high-speed processing in order to cope with the complexity and diversification of display images, and the amount of heat generated from the display sub-base is also high. More than the previous display sub-base.

  In addition to display panels, pachinko machines are equipped with LED lights, light bulbs, etc., speakers that emit sound effects, etc. to improve decoration and interest, and a control base for controlling these. Provided on the back. Furthermore, a control base called a main base and a payout base for controlling the jackpot determination and prize ball payout are also provided.

  As described above, each function of the pachinko machine is controlled independently by a plurality of modular control boards, and heat is released from each of these control boards. It has become.

  Further, from the viewpoint of preventing tampering, the control boards are provided on the back of the pachinko machine in a state of being accommodated in the case so that the tweezers and electrodes that are not externally touch the control board. . Therefore, the case is usually provided with a through hole as an intake port and a heat dissipation port (see, for example, Patent Document 1).

In recent pachinko machines, in order to further enhance the interest, the display by electrical decoration becomes flashy, the display panel becomes larger and the displayed image is complicated and diversified, and it is generated from the control base The amount of heat is increasing. Therefore, the number of holes for heat dissipation provided in the case covering the control board tends to increase.
JP 2001-310037 A Japanese Patent Application Laid-Open No. 2000-144031

  However, simply providing a heat-dissipating hole in the case containing the control board has contributed to the low temperature of the control board, but has caused the following problems.

  That is, on the back of the pachinko machine, in addition to the control base, a ball tank and a tank rail for storing game balls are arranged. These ball tanks and tank rails are provided above the control base and are connected to a payout device for paying out a predetermined number of game balls, so that payout can be made based on the timing of the game balls entering the winning opening. In this way, the game ball is kept waiting (see, for example, Patent Document 2).

  In recent pachinko machines, there is a problem that the stored game balls become hot due to the heat released from the control base etc., and the player feels uncomfortable when the players touch the game balls discharged outside the machine. It has occurred.

  In view of the above problems, the inventors of the present invention, as a result of diligent research and efforts, are that the temperature of the game ball rises excessively because the heat released by the control base disposed under the ball tank or tank rail is the tank rail. It is found that it is caused by directly warming the game ball through the through hole for dust removal provided in the case, and further, by controlling the heat release site by the shape of the case housing the control base, the above problem is solved. The present invention was completed by conceiving that it could be solved.

  That is, an object of the present invention is to suppress the temperature rise of the stored game balls as much as possible.

  In order to achieve the above object, a pachinko machine according to the present invention includes a storage means for storing game balls, a control base for controlling the pachinko machine, and a box-shaped base case for housing the control base at the back. In the pachinko machine, the storage means includes an inclined bottom portion for supplying game balls to the payout device, and the bottom portion is provided with a penetrating discharge hole for discharging dust, and the storage means The upper surface wall of the base case disposed immediately below is provided along the slope of the bottom of the storage means, and includes a heat radiating hole near the highest position of the upper surface wall. The discharge hole is not arranged at the bottom of the storage means facing upward.

  As a result, the heat generated in the control board rises inside the base case along the upper surface wall of the base case, and is radiated to the outside of the case from the heat radiating hole provided at a predetermined position. On the other hand, since the discharge hole is not disposed in the portion of the storage means that is directly above the upper surface wall and faces the heat dissipation hole, the heat does not directly reach the stored game ball.

  Therefore, even if the game ball is stored for a long time, the temperature of the game ball does not increase, so even if the player touches the game ball immediately after discharge, the amount of heat transferred to the game ball decreases, Discomfort given to the player can be reduced. That is, the present invention provides a pachinko machine that can reduce discomfort given to the player.

  Furthermore, since the heat radiating hole is not arranged in the portion of the base case that faces the discharge hole of the storage means, it is possible to avoid the dust falling from the discharge hole from entering the base case, resulting in malfunction of the control base. It can be avoided.

Is provided on the tank rail 116.

  The tank rail 116 functions as a storage unit that stores the game ball 130 until the game ball 130 is paid out to the upper plate 114 by the payout device at some timing.

  FIG. 3 is a plan view showing the pachinko machine 100 from the back.

  The figure shows a cross section of the bottom 118 of the tank rail 116 with a part of the tank rail 116 cut away.

  As shown in the figure, a plurality of penetrating discharge holes 117 are provided in the bottom 118 of the tank rail 116. The discharge hole 117 is provided to discharge dust that has entered the tank rail 116 from the tank rail 116, and the dust falls from the discharge hole 117 to the outside and is discharged from the tank rail 116. Thus, the smooth rolling can be maintained without the game ball 130 being caught by dust and staying behind.

  In the case of the present embodiment, the discharge hole 117 is not disposed directly above the heat radiation hole 146 provided in the base case 141 described later, that is, in a range facing the heat radiation hole 146 upward from the vertical line.

  Next, the base case 141 will be described in detail.

  FIG. 4 is a perspective view showing a base case 141 for a display sub-base.

  As shown in the figure, the base case 141 is a case that houses the display sub-board 121 and also the liquid crystal unit 152 for display. The case main body 151 that holds the liquid crystal unit 152, and the display sub-board It has a two-chamber structure with a projecting portion 142 that houses 121. The protrusion 142 includes an upper surface wall 143, a side wall 144, and a lower surface wall 145 that are integrally provided upright from the case main body 151.

  When the base case 141 is attached to the back surface of the pachinko machine 100, the top wall 143 is erected on the base case 141 main body along the bottom surface of the tank rail 116. In addition, a heat radiating hole 146 for releasing heat generated in the display sub-board 121 is provided only in the vicinity of the highest position of the upper surface wall 143 having the inclination. In the protrusion 142, other heat radiating holes 147 are also provided in the walls 144 and 145, and these heat radiating holes 146 and 147 also function as inlets for introducing external air.

  As shown in FIG. 4, the base case 141 is fixed by inserting screws (not shown) through screw holes 153 provided in a plurality of locations in a protruding state above and below the base case 141. The base case 141 is fixed to the back portion of the pachinko machine 100 by screwing by screwing to the board.

  The display sub-board 121 accommodated in the board case 141 is a board that controls various displays such as reach actions displayed on the liquid crystal display that can be viewed through the window frame 113 from the front surface of the pachinko machine 100. And a ROM in which the movement is recorded and a CPU for displaying them are attached.

  Due to the configuration of the base case 141, the heat generated in the display sub-base 121 moves inside the base case 141 along the inclination of the upper surface wall 143, and from the heat radiation hole 146 provided in the vicinity of the highest part of the inclination. It is discharged outside the substrate case 141.

  In addition, due to the configuration of the tank rail 116 and the base case 141, the heat discharged from the heat radiating hole 146 of the base case 141 rises and reaches the lower surface of the tank rail 116, but a portion facing the heat radiating hole 146. Since the exhaust hole 117 is not disposed in the, the exhausted heat does not reach the game ball 130 in the directly stored state. Therefore, even if the player touches the game ball 130 paid out to the upper plate 114, the amount of heat transmitted to the game ball 130 is reduced, so that discomfort given to the player can be reduced.

  Furthermore, with the above configuration, it is possible to prevent dust that has fallen from the discharge hole 117 from reaching the display sub-board 121 as much as possible. That is, even if dust falls from the discharge hole 117, since the heat radiating hole 117 is not arranged in the upper surface wall 143 of the base case 141 immediately below it, it is possible to prevent dust from entering the base case 141. Thus, it is possible to avoid malfunction of the display sub-board 121 as much as possible.

  In the present embodiment, the base immediately below the tank rail 116 has been described as the display sub-base 121 and the case 141 that accommodates it. However, the present invention is not limited to this, and the base right below the tank rail 116 is provided. Even if another base and its base case are arranged, the same actions and effects can be obtained.

  In the present embodiment, the tank rail 116 is disposed below the ball tank 115. However, the storage means is not limited to this mode, and the ball tank 115 and the tank rail 116 are disposed on the left and right. It may be done. Further, the relationship between the size of the ball tank 115 and the length of the tank rail 116 may be arbitrary.

(Embodiment 2)
Next, another embodiment will be described.

  This embodiment is an embodiment in which a barrier 150 is provided that prevents the game ball 130 in a stored state from directly facing when facing the heat radiation hole 117 vertically upward.

  Since the configuration of the second embodiment is substantially the same as that of the first embodiment, the components having the same functions are denoted by the same reference numerals, and only portions different from the first embodiment will be described here.

  Although the discharge hole 117 is provided in the bottom part 118 of the tank rail 116, in the case of this Embodiment 2, the discharge hole 117 is arrange | positioned over the bottom part front surface of the tank rail 116. FIG.

  Above the discharge hole 117 provided in the upper surface wall 143 of the base case 141, a barrier 150 is integrally provided in parallel with the upper surface wall 143 at a predetermined distance. The barrier 150 is attached in a protruding state from the base case 141 so as to cover the entire heat radiation hole 146 provided in the upper surface wall 143 and to cover the discharge hole 117 disposed above.

  With the above configuration, the heat from the display sub-board 121 discharged from the heat radiation hole 146 of the upper surface wall 143 rises along the barrier 150. Therefore, even if the discharge hole 117 exists immediately above the heat release hole 146, the heat from the heat release hole 146 does not directly heat the game ball 130 through the discharge hole 117, and the same action as in the first embodiment. There is an effect.

  Furthermore, since the above-described effects can be obtained without using the tank rail 116 having a special structure, the versatility is high.

  The barrier 150 does not need to be integrated with the base case 141, and may be separately attached with an adhesive or the like. Furthermore, not only the base case 141 but also the tank rail 116 may be attached. Further, it may be attached to another part of the pachinko machine 100.

  Furthermore, as the material of the barrier 150, an arbitrary material such as resin, wood, or metal can be selected. However, a material with low thermal conductivity is desirable. This is because in the case of the barrier 150 having high thermal conductivity, the game ball 130 may be heated by heat radiation from the barrier 150 itself.

  Further, the shape of the barrier 150 is not limited to a plate shape, and the upper surface wall 143 including the heat radiation holes 146 and the barrier 150 may be cylindrical (chimney shape).

  INDUSTRIAL APPLICABILITY The present invention can be used for a pachinko machine, and in particular, can be used for a pachinko machine equipped with a control base that generates a large amount of heat.
