Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a winning device for a pachinko machine, which is provided with an opening / closing member on the front surface of a mounting board, which can be changed into a state in which it is difficult to enter and a state in which it is easy to enter, and in which the opening / closing member is operated by a solenoid. .

[0002]

[Prior art]

 Conventionally, as a winning device, for example, an opening is provided on the front surface of a mounting board to be mounted on a game board, and an opening / closing door that can be tilted forward is pivotally attached to the opening. There is a box frame attached to the box frame, a detector for detecting general prize balls and special prize balls is provided in the box frame, and there is a box frame equipped with a solenoid for operating the opening / closing door on the back side of the box frame. .

According to this winning device, when the hit ball hit on the game board surface enters a specific winning opening and enters a specific game state that is advantageous to the player, the opening / closing door is opened by exciting a solenoid. It is maintained until a fixed time elapses (for example, 30 seconds) or until a predetermined number (for example, 10) of winning balls are generated, and the solenoid is demagnetized to be closed. There is. When a special winning ball is detected when the opening / closing door is opened, the opening / closing door is closed and then opened until a certain period of time elapses again or until a predetermined number of winning balls are detected. Is detected a predetermined number of times (for example, 16 times).

[0004]

[Problems to be solved by the device]

 By the way, in this type of prize winning device, if a special winning ball is detected while the opening / closing door is opened, it will detect a predetermined number of winning balls until a certain time elapses again after the opening / closing door is closed. Since it remains open until this time, if this operation is repeated, the solenoid itself will generate heat abnormally, causing a failure. Therefore, the present invention has been made to solve the above-mentioned problems, in which the outer circumference of the solenoid is surrounded by a heat dissipation plate to promote heat dissipation, and the solenoid does not malfunction due to the strong residual magnetism that accompanies this. The purpose is to provide a winning device for a pachinko machine.

[0005]

[Means for Solving the Problems]

 In order to achieve such an object, the present invention provides an opening / closing member on the front surface of the mounting substrate that can be changed into a state in which it is difficult to enter a hit ball and a state in which it is easy to enter, and a solenoid for operating the opening / closing member on the back surface side of the mounting substrate. In the prize winning device provided, the solenoid is surrounded by a heat radiating plate made of metal, and a through hole is formed in the heat radiating plate at a position facing the plunger tip end of the solenoid.

[0006]

[Action]

 The heat radiation of the solenoid is promoted by a heat radiation plate surrounded by the outer circumference. In addition, a through hole is provided at the position facing the plunger tip of the heat sink to prevent the heat sink from being magnetized, so even if the solenoid is continuously energized for a long time, The magnetic field lines having a high magnetic flux density passing along the axial direction pass through the through holes and do not pass through the heat sink, so that the heat sink is not strongly magnetized. As a result, strong residual magnetism does not occur in the heat sink, so that even when the solenoid is excited, the plunger does not remain attracted to the heat sink but is normally attracted, and the door can be opened reliably. .

 An embodiment of a winning device for a pachinko machine according to the present invention will be described below with reference to the drawings. FIG. 1 is a front view of a pachinko machine to which the winning device according to the present invention is applied. In the figure, 1 is a front frame of the pachinko machine P, 2 is a glass door frame mounted on the front surface of the front frame 1, and 3 is a front plate mounted on the front frame 1 below the glass door frame 2. Reference numeral 4 denotes a game board arranged on the back side of the front frame 1, and a game section 6 surrounded by a rail 5 is formed on the front surface thereof. In addition to a general winning opening 7, a variable display device 8, a starting winning opening 9 and a winning device A according to the present invention are mounted on the game section 6.

FIG. 2 is a perspective view of the winning device seen from the front, FIG. 3 is a perspective view of the same seen from the back, FIG. 4 is an exploded perspective view of the same, and FIG. The inside 11 is a mounting board to be mounted on the game board 4, and a horizontally long opening 12 is opened in the center thereof. Reference numeral 13 is a door-like opening / closing member whose lower end is pivotally supported and which tilts forward freely to open / close the opening 12. One end of each of the support shafts 15 and 15 is inserted into shaft cylindrical portions 14 and 14 provided on both sides of the lower end, respectively. The other end is pivotally supported by bearings 16 and 16 provided on both inner sides of the opening 12 of the mounting substrate 11. A pair of support pieces 17, 17 for supporting the tilted state are provided on the front surface of the opening / closing member 13 so as to project left and right, and a spur gear-shaped tooth portion 18 is provided on the outer periphery of the shaft cylinder portion 14 at one end. It is provided.

In addition, 19 and 19 are general winning a prize holes which are symmetrically attached to the left and right sides of the front surface of the mounting board 11, and the winning balls entering the winning holes 19 and 19 are guided to the back side of the game board. It is designed to be discharged to people. Further, 20 and 20 are illuminators that illuminate the inside of the winning holes 19 and 19 from the back side of the mounting substrate 11, and 21 and 21 are cover members that protect the back surfaces of these illuminators 20 and 20.

Reference numeral 22 denotes a box frame provided on the rear surface of the mounting substrate 11 so as to communicate with the opening 12. The bottom of the box frame 22 is provided with a receiving plate 23 which is inclined downward to one side. A ball receiving port 24 is opened at the downstream end, and a detector 25 for detecting a general winning ball is attached. Further, a ball receiving opening 26 is opened on the other side of the receiving plate 23, and a detector 27 for detecting a special winning ball is attached.

Reference numeral 28 denotes a solenoid for operating the opening / closing member 13, which is mounted on the back surface of the back cover 22 a of the box frame 22. The solenoid 28 has a known construction in which an electromagnetic coil 30 is housed in a metal holding frame 29, and a plunger 31 which freely moves back and forth from the lower surface of the holding frame 29 is inserted in the electromagnetic coil 30. A coil spring 32 is wound around the plunger 31. A rod 34 having a rack 33 vertically provided on the front end face is fixed to the lower end of the plunger 31, and the rack 33 is engaged with a tooth portion 18 provided on one side of the opening / closing member 13.

When the solenoid 28 is demagnetized, as shown by the solid line in FIG. 5, the plunger 31 projects downward from the holding frame 29 by the elastic force of the coil spring 32 to raise the opening / closing member 13 and close the opening 12. Is made. When the solenoid 28 is excited, the plunger 31 is attracted into the holding frame 29 against the elastic force of the coil spring 32 as shown by the chain line in FIG. Is opened.

Therefore, in FIG. 1, for example, when a hit ball that has been hit on the surface of the game board 4 flows down, it enters the starting winning opening 9 provided on the surface of the game board 4 and is detected by the detector 10. Then, a fixed amount of prize balls corresponding to one winning ball is paid out, and the variable display device 8 mounted on the game board 4 is electrically operated. Therefore, the display of a plurality of numbers, characters, patterns, etc., displayed on the variable display portion 8a provided on the front surface of the variable display device 8 starts to randomly change, and each display is stopped after a predetermined time elapses. At the time of this variable stop, if each display is stopped with the same number, character or design as the preset display symbol, a specific game state that is advantageous to the player is achieved.

In this specific game state, the solenoid 28 is excited and the plunger 31 is attracted, the opening / closing member 13 is tilted forward, and the opening 12 elapses for a predetermined time, or a predetermined number of detectors 25 and 27 ( It is opened until the winning balls of 10 pieces, for example, are detected, and when the solenoid 28 is demagnetized after that, the opening / closing member 13 is erected and the opening 12 is closed. When one of the winning balls enters the ball receiving port 26 and is detected by the detector 27, the opening / closing member 13 is closed for a certain time (for example, 2 seconds) and then opened again. The above operation is performed a predetermined number of times (for example, 16 times) as long as is continued.

Therefore, in FIG. 4, reference numeral 35 denotes a metal heat radiating plate surrounding the outer circumference of the solenoid 28. The heat dissipation plate 35 is in a substantially U-shape in plan view which is in contact with the holding frame 29 and surrounds the solenoid 28 and the two outer side surfaces of the plunger 31, and the bottom 35a of the heat dissipation plate 35 surrounds the lower end of the plunger 31. There is. A through hole 36 is formed in the bottom portion 35a so as to face the lower end portion of the plunger 31.

A mounting piece 35b is provided on one side of the heat dissipation plate 35, and two small holes 37, 37 are formed through the mounting piece 35b. These small holes 37, 37 are shown in FIG. As shown in the drawings, the screws 39 and 39 are screwed into the shaft cylinders 38 and 38 so as to match the shaft cylinders 38 and 38 which are projected on the rear surface of the back cover 22a of the box frame 22. Further, two small holes 40, 40 are also provided on the other side so as to match the screw holes 41, 41 provided on the side surface of the solenoid 28, and the screws 42, 42 are screwed into the respective screw holes 41, 41. By doing so, the heat dissipation plate 35 is fixedly provided on the back surface of the mounting substrate 11.

Even if the solenoid 28 surrounded by the heat radiating plate 35 is continuously excited for a long period of time, the heat radiating plate 35 promotes heat radiation so that the solenoid 28 does not generate abnormal heat. Moreover, since the through hole 36 is formed at a position facing the tip of the plunger 31 of the bottom portion 35a, the magnetic flux having a high magnetic flux density flowing along the axial direction of the plunger 31 passes through the through hole 36, Since it does not pass through the inside of the heat dissipation plate 35, the heat dissipation plate 35 is hardly magnetized strongly, so that strong remanence is not generated.

[0018]

[Effect of device]

 As described above, in the winning device for the pachinko machine according to the present invention, the solenoid is surrounded by the heat dissipation plate, so that the heat dissipation effect is improved and the failure due to abnormal heat generation is reduced. At the same time, a through hole was opened in the heat sink facing the tip of the plunger.Therefore, even if the solenoid was excited continuously for a long time, strong residual magnetism did not occur in the heat sink. It is possible to prevent an erroneous operation in which the opening / closing member does not open because it remains adsorbed, and it is possible to always perform the opening / closing operation of the opening / closing member accurately according to the set conditions. This also has the advantage that the life of the solenoid itself is extended and it is economical.
