Description

  The present invention relates to a winning device in a pachinko machine.

Generally, a pachinko machine has a substantially vertical game board, and a substantially vertical glass window is disposed on the front side of the game board. A pachinko ball (game ball) launched from the launcher rolls on the game board (in the space between the game board and the glass window).
And, in many pachinko machines, an accessory (center accessory) is provided almost at the center of the game board, a start winning opening is provided below, and a large winning opening (winning device) is provided below that. It has been.
When the pachinko ball that has rolled on the game board enters the start winning opening, the symbol on the display part of the center bonus is displayed in a variable manner for a predetermined time, and then the final symbol is statically displayed. The symbols displayed in a stationary manner include “win” and “off”, and in the case of “win”, the special winning opening is opened a predetermined number of times. As a result, a plurality of pachinko balls can enter (win) in the big prize opening (winning device), and a large number of pachinko balls are paid out from the prize ball payout device as winning balls.

By the way, in recent years, there is a tendency that the display and the like in the center role are also elaborated, and accordingly, the size of the center role is increasing.
On the other hand, the size of the game board (game area) is basically a predetermined size.
For this reason, it is required to shorten the dimension (particularly the height dimension) of the winning device (large winning opening) accordingly.

Here, the following is an example of a conventional winning device.
As shown in FIG. 5, the winning device 130 has a board portion 151 that is attached in contact with the front surface of the game board 111, and an opening 152 is formed in the board portion 151. Yes.
The opening / closing door 160 is provided with respect to the opening 152 so as to be swingable between a closed position and an open position about a rotation shaft 164 positioned below the opening 152.
As shown in FIG. 5A, the open / close door 160 extends in a substantially vertical direction (ie, substantially parallel to the game board 111) from the base end portion toward the tip end portion in a state of being in the closed position. The front end portion is positioned at a position in the depth direction substantially the same as the substrate portion 151, and the opening 152 is closed. Further, as shown in FIG. 5B, the opening / closing door 160 opens the opening 152 with its front end positioned on the front side of the substrate 151 in a state of being in the open position.

  And in the state which the opening / closing door 160 is located in an open position (FIG.5 (b)), the distance between the front-end | tip part of the opening / closing door 160 and the glass window 112 needs to become below predetermined. Otherwise, pachinko balls (pachinko balls that flow down the glass window 112 side) flow through the space between the open / close door 160 and the glass window 112 at the open position, This is because the gap with the glass window 112 is clogged and the winning device 130 cannot be won smoothly.

Here, in the pachinko machine, the distance between the game board 111 and the glass window 112 is generally a predetermined dimension.
For these reasons, the opening / closing door 160 is in the closed position (FIG. 5A), and its height dimension (to be precise, between the pivot shaft 164 and the tip of the opening / closing door 160). (Dimensions) are required to be greater than a predetermined value.
Along with this, the winning device 130 (opening 152) needs to have a height dimension that is greater than or equal to a predetermined height, which is a bottleneck in reducing the height of the winning device 130.

  An object of this invention is to shorten the height dimension of a winning device, ensuring a predetermined height dimension about an opening / closing door.

  In order to achieve the above object, the invention according to claim 1 is directed to a board portion attached in contact with a front surface of a game board, an opening formed in the board portion, and the opening. A closed position that closes the opening with its tip positioned at substantially the same depth direction position as the substrate, with a pivot shaft positioned below the opening as the center, and its tip And an opening / closing door that is disposed to be swingable between an opening position where the opening portion opens and the opening portion opens, and the opening / closing door is located at the closed position. In the state, it is a winning device for a pachinko machine that is inclined from the vertical so as to go upward and toward the near side from the base end portion toward the tip end portion.

  Here, “inclined from the vertical so as to go upward and toward the near side” is not limited to a flat plate shape (linear shape in the longitudinal section), but a curved plate shape (curved shape in the longitudinal section). Cases are also included.

In the winning device of the pachinko machine according to the present invention, in a state where the opening / closing door is located at the closed position, the opening / closing door is directed from the vertical so as to go upward and toward the front side from the base end portion toward the tip end portion. Since it is inclined, it can have a longer height dimension in the state of being in the closed position than in the vertical case.
Therefore, conversely, even if the height of the substrate (its opening) is shorter, the height of the door (the distance between the pivot shaft and the tip of the door) is not open. It is possible to secure the length required for positioning at the position.
Thus, in this winning device, the height dimension of the opening can be shortened, and the height dimension of the substrate portion (winning device) can be shortened.

  The invention according to claim 2 is the winning device for the pachinko machine of the invention according to claim 1, wherein the thick portion at the upper edge portion of the opening portion is directed toward the front side from the lower side to the upper side. The pachinko machine winning device is formed with an inclined portion that is inclined from the horizontal as described above, and the opening / closing door overlaps with the inclined portion when the door is in the closed position.

  “Inclined from the horizontal so that it goes from the bottom to the top as it goes from the bottom to the top” includes not only the planar shape (linear shape in the longitudinal section) but also the curved surface shape (curved shape in the longitudinal section). .

In the pachinko machine winning device according to the present invention, in addition to the operations and effects of the pachinko machine winning device according to the first aspect, the following operations and effects can be obtained.
That is, in this winning device, an inclined portion is formed in the thick portion at the upper edge portion of the opening of the substrate portion, and in the state where the opening and closing door is located at the closed position, the front end portion of the opening and closing door is It overlaps with the inclined part (substrate part).
For this reason, the inclined part is not formed in the thick part at the upper edge part of the opening part of the board part, and the opening and closing door is opened and closed as compared with the case where the front end part of the opening / closing door in the closed position does not overlap the board part. The door can have a long height dimension.
Therefore, conversely, even if the height of the substrate (its opening) is shorter, the height of the door (the distance between the pivot shaft and the tip of the door) is not open. It is possible to secure the length required for positioning at the position.
Thus, in this winning device, also in this respect, the height of the opening can be shortened, and the height of the substrate portion (winning device) can be shortened.

  As described above, according to the present invention, the height dimension of the board portion (winning device) can be shortened, and the bonus can be increased accordingly.

The plunger 92 is in a protruding state when the solenoid 90 is in a non-excited state, and the plunger 92 is immersed when the solenoid 90 is in an excited state. State. A flange-like engaging portion 93 is formed at the distal end portion of the plunger 92.

A rotating member 95 is disposed between the plunger 92 and the opening / closing door 60.
The rotation member 95 has a rotation shaft 96, and the rotation shaft 96 is rotatably fitted to a pair of groove-like rotation shaft fitting portions 46 a and 46 b provided on the base member 40. ing. The rotation shaft fitting portions 46 a and 46 b are closed by the stage forming member 70.
In this way, as shown in FIG. 4, the rotation member 95 can be rotated about the rotation shaft 96.

As shown in FIG. 3, an engaged portion 97 and an action portion 98 are formed on the rotating member 95. Both are formed so as to extend in two directions with an angle of approximately 90 degrees around the rotation shaft 96.
An engaged portion 93 of the plunger 92 is engaged with the engaged portion 97. For this reason, when the plunger 92 is displaced between the protruding state and the immersed state, the action part 98 (the tip part) is moved between the lowered position (FIG. 4A) and the raised position (FIG. 4B). Displace between.

As described above with reference to FIG. 2B and the like, plate-like portions 62 a and 62 b are formed at the left and right edges of the opening / closing door 60. The left plate-like portion 62a is formed larger than the right-side plate-like portion 62b, and a notched engaged portion 65 is formed in the left plate-like portion 62a. As shown in FIG. 4, the action portion 98 of the rotating member 95 is engaged with the engaged portion 65.
For this reason, as shown to Fig.4 (a), in the state which the action part 98 is located in a lowered position, the opening / closing door 60 is located in a closed position. On the other hand, as shown in FIG. 4B, the opening / closing door 60 is located at the open position in a state where the action portion 98 is located at the raised position.
The dimensions of each member and the mutual positional relationship are set so as to be like that.

  As shown in FIG. 4, an inclined portion 55 is formed in the thick portion of the upper edge portion of the opening portion 52 of the substrate portion 51 (front plate member 50). The inclination part 55 inclines from the horizontal so that it may go to the near side as it goes upwards from the downward direction.

As shown in FIGS. 2 (a) and 4 (a), in the state where the door 60 is in the closed position, the door 60 is directed upward and toward the near side from the proximal end portion toward the distal end portion. It is inclined from the vertical.
In addition, in a state where the open / close door 60 is located at the closed position, the tip end portion is located at the substantially same depth direction position as the substrate portion 51. The front end (upper end) of the opening / closing door 60 overlaps the inclined portion 55 of the opening 52.

In addition, as shown in FIGS. 2B and 4B, the opening / closing door 60 is positioned at the front side of the substrate 51 in the state where the opening / closing door 60 is positioned at the open position. At that time, the opening / closing door 60 is slightly inclined so as to gradually move upward as it goes from the base end portion to the tip end portion.
At that time, the distance between the opening / closing door 60 (the tip thereof) and the glass window 12 is set to a predetermined value or less. That is, the pachinko ball does not flow down through the gap between them, and the pachinko ball is not clogged in the gap, and the pachinko ball is smoothly received by the open / close door 60 and passes through the opening 52. The winning device 30 is configured to win a prize.

Next, the operation of the winning device 30 of this pachinko machine will be described.
As described above with reference to FIG. 4A, in this winning device 30, the open / close door 60 is in the closed position with respect to the substrate portion 51 (its opening portion 52) that is substantially vertical and substantially parallel to the glass window 12. Even in the positioned state, as it goes from the base end portion to the tip end portion, it is inclined from the vertical so as to go upward and toward the near side.
Therefore, under the condition that the height of the substrate portion 51 (the opening portion 52) is a predetermined one, the opening / closing state is higher than that in the case where the substrate portion 51 is in the closed position and is vertical (see FIG. 5A). The door 60 can have a long height dimension.

Therefore, conversely, even if the height of the substrate 51 (the opening 52) is short, the opening / closing door 60 (precisely, the rotation shafts 64a and 64b and the tip of the opening / closing door 60 are not connected. The distance between them can ensure a height dimension (a dimension at which the distance between the front end portion and the glass window 12 is equal to or less than a predetermined value) required when positioned at the open position.
Thus, in this winning device 30, the height dimension of the opening 52 can be shortened, and the height dimension of the substrate portion 51 (winning device 30) can be shortened.

In addition, as described above with reference to FIG. 4A, in the winning device 30, the inclined portion 55 is formed in the thick portion at the upper edge portion of the opening 52 of the front plate member 50. In a state where the opening / closing door 60 is located at the closed position, the front end portion of the opening / closing door 60 overlaps the inclined portion 55 (substrate portion 51) of the opening 52.
For this reason, the thick part in the upper edge part of the opening part 52 (152) of the board | substrate part 51 (151) is provided on condition that the height dimension of the board | substrate part 51 (the opening part 52) is a predetermined thing. From the case where the inclined portion 55 is not formed on the front end of the opening / closing door 60 (160) in the closed position and does not overlap the substrate portion 51 (151) (see FIG. 5A). Also, the door 60 can have a long height dimension.

Therefore, conversely, even if the height of the substrate 51 (the opening 52) is short, the opening / closing door 60 (precisely, the rotation shafts 64a and 64b and the tip of the opening / closing door 60 are not connected. The distance between them can ensure a height dimension (a dimension at which the distance between the front end portion and the glass window 12 is equal to or less than a predetermined value) required when positioned at the open position.
Thus, in this winning device 30, the height dimension of the opening 52 can be shortened also in this respect, and the height dimension of the substrate portion 51 (winning device 30) can be shortened.

  Note that the above is merely an embodiment of the present invention, and it is needless to say that the present invention can be implemented in various modifications based on the knowledge of those skilled in the art.
