It is composed of

FIG. 12 is a front view showing a conventional example of this type of gaming machine. In the figure, a machine frame, a game board, a launching device, a glass door, a front plate door and a front plate portion are indicated by reference numerals 200, 202, 204, 206, 208 and 210, respectively. The firing device 204 is configured to interlock with an operation handle 212 operated by a player.

In this conventional gaming machine, the front plate 21
0 is configured to include an upper plate portion 214 and a lower plate portion 216 that are vertically arranged on the front surface of the front plate portion door 208. The firing device 204 has a holder 218 that holds the pachinko ball to be fired at the firing position. Pachinko balls to be fired are supplied to the holder 218 from the upper plate portion 214 one by one.

[0008] The launching device 204 is configured to launch the supplied pachinko ball diagonally upward along a holder 218 by a launching tool (not shown). After the released pachinko ball is released from the holder 218,
By first contacting the rail 220 attached to the game board 202 and then proceeding along the rail 220, the player is guided to a game area arranged in the center of the game board 202.

[0009]

In this type of gaming machine, the lowermost position of the game board 202 is generally determined mainly by the lowermost position of the rail 220. If the lowermost position of the rail 220 is set higher, the lowermost position of the game board 202 can also be set higher, but the lowermost position of the rail 220 is such that the pachinko ball fired by the firing device 204 first It is set so that a proper contact state of properly contacting the rail 220 is guaranteed.

[0010] Here, the "appropriate contact state" means that the pachinko ball first contacts the rail 220 at a sufficiently small angle, so that the contact causes a large repulsive force from the rail 220 to the pachinko ball (that is, the pachinko ball). Ball 2 on Rail

Further, in this type of game machine, generally, the uppermost position of the front plate door 208 mainly corresponds to the front plate 210
Is determined by the height of the pachinko ball, which determines the storage capacity of the pachinko ball. In order to set the lowermost position of the glass door 206 low, the height of the front plate 210 may be set short, but in this case, the storage capacity of the pachinko ball by the front plate 210 tends to decrease. is there.

On the other hand, if the uppermost position of the front plate door 208 is set higher, the lowermost position of the glass door 206 is set higher accordingly.

In the conventional gaming machine shown in FIG. 12, the front plate door 208 is secured while ensuring the proper contact state.
In order to secure the storage capacity of the game board 202, the lowermost position of the game board 202 is set lower than the uppermost position of the front plate door 208 as shown in FIG. It was set lower than the lowermost position of the door 206.

In this conventional gaming machine, as described above, the gaming board 202 is removably mounted on the machine frame 200 by a worker in front of the machine frame 200.

However, in this conventional gaming machine, the lowermost position of the game board 202 is set lower than the uppermost position of the front plate door 208 as described above. The game board 202 is covered not only by the glass door 206 but also by the front plate door 208. for that reason,
It was indispensable to carry out the attaching / detaching work of the game board 202 with not only the glass door 206 but also the front plate door 208 opened. FIG. 13 is a side sectional view showing the height relationship among the lowermost position of the game board 202, the lowermost position of the glass door 206, and the uppermost position of the front plate door 208.

Therefore, in this conventional gaming machine,
The attaching / detaching operation of the game board 202, that is, the exchange operation, necessarily involves the opening and closing operation of the glass door 206 and the opening and closing operation of the front plate door 208, and therefore, the exchange operation of the game board 202 cannot be performed with sufficiently high efficiency.

This is to facilitate understanding of some of the technical features described in the present specification and some of the combinations thereof, and the technical features and the combinations thereof described in the present specification have the following aspects. It should not be construed as limited.

(1) A machine frame which is used by mounting a game board for a player to play a game using a pachinko ball, and which is detachably mounted by a worker in front of the machine frame. And a launching device that launches a pachinko ball toward a game board mounted on the machine frame in accordance with the operation of the player, and the machine frame adjacent to each other in the height direction of the machine frame. A glass door and a front plate portion door that cover the front of the machine frame, both of which can be opened and closed with respect to the machine frame by rotation about a rotation axis extending in the height direction of the machine frame. In its closed state, it is intended to cover a game area partially set on the front surface of the game board mounted on the machine frame from the front side thereof in a see-through manner,
The front plate portion door has a front plate portion that has a storage function of storing a pachinko ball paid out as a prize in response to the pachinko ball fired by the firing device entering the hit hole of the game board. In the gaming machine including the above, only the glass door of the glass door and the front plate door, in its closed state, covers the front of the game board mounted on the machine frame, Gaming machine to do. In this gaming machine, only the glass door of the glass door and the front plate door is
In its closed state, it covers the front of the game board mounted on the machine frame. Therefore, according to this gaming machine, the attaching / detaching operation of the gaming board, that is, the replacing operation, must be accompanied by the opening / closing operation of the glass door, but the opening / closing operation of the front plate door is not required. It becomes possible to perform the exchange work of the board with a sufficiently high efficiency. (2) In the game area, a plurality of nails are erected to affect the course of the pachinko ball by colliding with the pachinko ball, and a generally arc-shaped rail is formed around the periphery of the game area by the firing. A pachinko ball fired by the device is provided to guide the ball to the game area, and the firing device is arranged along a straight line contacting the rail and extending generally parallel to the height direction of the machine frame. The gaming machine according to the mode (1), wherein the game machine fires a pachinko ball. As for the launching device, a slanting launching method in which a pachinko ball is launched obliquely upward as in the above-described conventional gaming machine shown in FIG. For convenience of distinction in terms of expression, this is referred to as a vertical firing method.). As described above, the lowermost position of the rail is set so as to ensure a proper contact state in which the pachinko ball fired by the firing device first makes proper contact. Therefore, as shown in FIG. 10, the firing position L in the firing device is in contact with a circumference C including an arc approximating the curved portion of the rail.
A tangent passing through P is assumed, and in the oblique firing method, as shown in FIG.
1 and a straight line (hereinafter, referred to as a “first straight line”) L1 that is in contact with the circumference C, whereas a straight line closer to the vertical than the first straight line L1 in the vertical firing system. (Hereinafter, referred to as “second straight line”) L2
It is said. Here, regarding the contact point CP with the circumference C, when comparing the first straight line L1 and the second straight line L2 with each other, the contact point CP2 between the second straight line L2 and the circumference C is the first straight line L
1 is higher than the contact point CP1 between the circle C and the circumference C. The fact that the contact point CP2 is higher than the contact point CP1 means that the lowermost position of the rail can be easily set higher when the vertical firing method is used than when the oblique firing method is used. This means that it is easier to set the lowermost position of the gaming board higher when the vertical firing method is used than when the oblique firing method is used. Here, the fact that it is easy to set the lowermost position of the gaming board higher means that even if the uppermost position of the front plate door is set in the same manner as in the above-mentioned conventional gaming machine, This means that the lowermost position of the panel need not be lower than the uppermost position of the front plate door. And
This means that only the glass door of the glass door and the front plate portion door can cover the front surface of the game board mounted on the machine frame in its closed state. . Based on the knowledge described above, in the gaming machine according to this section, it is assumed that the launching device launches the pachinko ball along a straight line contacting the rail and extending substantially parallel to the height direction of the machine frame. ing. Therefore, according to this gaming machine, it is easy to set the lowermost position of the gaming board high by optimizing the firing angle of the launching device. As a result, the front of the gaming board mounted on the machine frame has a glass door. , But not by the front plate door. In this section, `` a straight line that is in contact with the rail and extends generally parallel to the height direction of the machine frame '' is a conventional gaming machine that fires a pachinko ball along that straight line and adopts an oblique firing method. Means a straight line at which the pachinko ball is fired at a firing angle closer to the vertical than the firing angle of the pachinko ball. If the firing angle of the pachinko sphere, which is the angle θ between the straight line and the horizontal line (the smaller of the two geometrically existing angles between the straight line and the horizontal line), is specifically illustrated by a numerical value, The angle θ can be 45 degrees or more, 55 degrees or more, 65 degrees or more, or 75 degrees or more. Further, the angle θ can be set to an angle within a range defined by two values that are shifted 17.5 degrees forward and backward from 78.5 degrees. (3) the front plate door has only one front plate,
The gaming machine according to (1) or (2), wherein the storage function is exhibited by the one front plate portion. If the lowermost position of the gaming board cannot be set lower than that of the conventional gaming machine, the uppermost position of the front plate door can be set lower than that of the conventional gaming machine. The front surface can be covered by the glass door, but not by the front plate door. On the other hand, if the number of pachinko balls that can be stored is improved relative to the height of the front plate door, the same storage capacity (that is, the number of pachinko balls that can be stored) is maintained while maintaining the height of the front plate door. And the uppermost position thereof can be set low. Also,
As a configuration of the front plate portion in the front plate portion door, as in the above-described conventional game machine shown in FIG. 12, the upper plate portion and the lower plate portion are vertically arranged with a gap therebetween, that is, independent from each other. In contrast to the case where the configuration using two front plates is adopted, if the configuration using one front plate, that is, the configuration where the upper plate and the lower plate are combined, is adopted, the number of parts is reduced and the number of components is reduced. Due to the reduction in space, etc., it tends to be easy to store a large number of pachinko balls for the height of the front plate door. Based on the knowledge described above, in the gaming machine according to this section, the front plate door has only one front plate, and the one front plate exerts a storage function. Therefore, according to this gaming machine, by optimizing the configuration of the front plate portion, it is easy to set the uppermost position of the front plate portion door low, and as a result, the front surface of the game board mounted on the machine frame becomes Although it is covered by the glass door, it is possible not to be covered by the front plate door.

The technology that enables the lowermost position of the game board 20 to be set higher than the lowermost position of the glass door 12 and the uppermost position of the front plate door 14 is based on the firing of the firing device 16. This is to optimize the angle and the configuration of the front plate 30.

FIG. 3 schematically shows the basic configuration of the launching device 16.

As is well known, the launching device 16 is provided with a pachinko ball having a strength corresponding to the degree of operation of the operation handle 33 (see FIG. 1) by the player. Fire towards 20.

To this end, the launching device 16 is provided with a holder 34 for holding a pachinko ball to be fired. Each time the firing operation is completed, one pachinko ball is supplied to the holder 34 from the front plate 30.
The firing device 16 further applies an impact force to the pachinko ball held by the holding device 34 in the direction in which it is to be fired, thereby firing the pachinko ball.
6 is provided. The launcher 36 is swung about one horizontal swing axis. In order to realize that swing,
The firing device 16 includes an actuator 38 such as a solenoid or a motor.

The firing device 16 fires the pachinko ball toward the rail 26 (see FIG. 1) so that the proper contact state is ensured. The firing device 16 employs the above-described vertical firing method instead of the above-described oblique firing method.
Specifically, the firing angle of the pachinko ball, that is, the angle θ between the holder 34 and the horizontal line is set to 78.5 degrees.

As described above, as a result of optimizing the firing angle of the firing device 16, as described above with reference to FIG. 10, the lowermost position of the rail 26 is changed to the conventional one in which the oblique firing method is adopted. It is possible to set higher than the pachinko machine, and furthermore, it is possible to set the lowermost position of the game board 20 higher than the conventional pachinko machine adopting the oblique firing method.

On the other hand, in order to optimize the configuration of the front plate 30, the front plate door 14 has only one front plate 30 as shown in FIG. This is realized by being designed to exhibit the storage function.

According to the front plate 30, as is apparent from the above description, the front plate 30 is composed of a conventional pachinko machine having an upper plate and a lower plate which are vertically arranged independently of each other. Compared with the machine, the storage capacity, which is the number of pachinko balls that can be stored in the front plate door 14 for the height dimension of the front plate door 14, can be easily increased. Therefore, the front plate door 14
Can be shortened, and as a result, the uppermost position of the front plate door 14 and the lowermost position of the glass door 12 can be set lower than the conventional pachinko machine.

As is apparent from the above description, according to the present embodiment, the lowermost position of the game board 20 is not lower than the lowermost position of the glass door 12 than the uppermost position of the front plate door 14. Only As a result, in the present embodiment, the front surface of the game board 20 is covered by the glass door 12 but not by the front plate door 14. Therefore, according to the present embodiment, as shown in FIG. 1, the attaching / detaching operation of the game board 20, that is, the replacing operation, involves opening / closing the glass door 12, but does not involve opening / closing the front plate door 14. As a result, the replacement operation of the game board 20 can be performed with sufficiently high efficiency.

It should be noted that, in this embodiment,
As shown in FIG. 2, the lower end of the glass door 12 and the front plate door 1
4 are overlapped with each other in their thickness direction, and the glass door 12 is located in front of the front plate door 14. And in this embodiment,
The uppermost position of the front plate door 14 is set higher than the lowermost position of the glass door 12.

Therefore, in this embodiment, it is not sufficient that the lowermost position of the game board 20 is higher than the lowermost position of the glass door 12, and the lowermost position of the game board 20 is the uppermost position of the front plate door 14. The higher value is also necessary for improving the efficiency of the exchange operation of the game board 20. In any case, game board 2
