It is designed to play the game in a depressed state. The game balls (called "safe balls") that have fallen into the winning tool are detected by a winning ball detector provided on each winning tool and discharged to the back side of the game board. At the lower end of the game area, an out port is formed for discharging a game ball (referred to as an “out ball”) that has fallen in the game area without falling into the prize device to the back side of the game board. When a winning ball detector detects a safe ball, a predetermined number of game balls according to the winning state are paid out from the ball payout device and guided to a ball plate provided on the front of the pachinko machine.
[0003]
On the back set board, a safe ball discharge path for flowing down the safe ball discharged to the back side of the game board and an out ball discharge path for flowing out ball are formed separately and independently. Are collectively referred to as a "gamed ball"), and a game-completed ball discharge passage is formed to collect and flow down the ball, and the ball is discharged from a ball discharge port formed at a lower end of the ball discharge passage to a collection bucket on the game facility side. It has become so.
[0004]

[0007]
[Problems to be solved by the invention]
Here, each of the above-mentioned ball discharge passages and payout passages has a large number of game balls flowing down per unit time, and each ball passage needs a constant cross-sectional area according to the passing amount. For example, even in a safe ball passage that is generally considered to have the smallest number of passages, the number of passages when a so-called big hit occurs rapidly increases, and a game in which the out ball discharge passage and the safe ball discharge passage are integrated is already played. In the ball discharge passage, the out ball and the safe ball are gathered and flow down, so that the number of passages is larger than in the individual ball discharge passage. In addition, recent pachinko machines tend to increase the amount of prize balls to be paid out per unit time in order to pay out prize balls in a short time and efficiently due to the occurrence of jackpots. The number of passages in the payout passage, which has a large number, is further increased. On the other hand, the area of the back set board cannot be larger than the frame size of the outer frame located on the outer periphery, and unless the plurality of spherical passages are formed within a limited fixed area and the passage cross-sectional area is secured. No. Therefore, conventionally, as a means for securing the cross-sectional area of each ball passage, the front-rear dimension (depth) of the ball passage has been enlarged, thereby securing the required passage cross-sectional area.
[0008]
However, in such a conventional path mechanism, if the cross-sectional area of the path is to be ensured, the dimension (thickness) of the back set board in the front-rear direction is increased, and the circuit board attached to the back side of the back set board is inevitable. The amount of rearward projection of the increases. This is not limited to problems such as deterioration in handling due to the increase in size of the pachinko machine.For example, when trying to install the game on a gaming island, the rear end of the pachinko machine is attached to the opposite surface of the gaming island. There is a problem that it may be difficult to install because of the interference with the rear end of the pachinko machine, or even if it can be installed, the required heat dissipation cannot be obtained because the required space cannot be secured behind the circuit board. .
[0009]
As a means for addressing the above problem, a circuit board may be made thinner. For example, in the case of a power supply board, for example, it is sufficient to mount one capacitor having a predetermined capacity. In order to achieve this, it is necessary to mount two small, short capacitors, which increases the number of mounted components and the complexity of circuit patterns, thereby increasing production costs. There is a problem that the heat dissipation effect may be increased and the heat radiation effect may be worsened than before.
[0010]
The present invention has been made in view of such circumstances, and under the same restrictions on the outer frame size as in the past, it is possible to make a back set board that is easy to increase in thickness dimension thinner, and thereby a game island It is an object of the present invention to provide a path mechanism of a ball-and-ball game machine that can solve the problem that it is difficult to install the circuit board on a board, the problem of the heat radiation effect of the circuit board, the problem of the circuit configuration of the circuit board, and the like.
[0011]

In order to achieve the above object, the present invention provides a game board having a game area formed on a front surface, a frame member for accommodating and holding the game board in an upright posture, and a ball dispensing device, which is provided on the back side of the game board. The present invention relates to a ball and ball game machine provided with a back set board which is always disposed so as to cover the back side of a frame member. In addition, on the front side of the back set board in this ball game machine, a back side discharge passage groove for guiding game balls discharged from the game board to a lower ball discharge port and a ball discharging device are paid out. A back side discharge passage groove for guiding game balls to the ball plate is formed to open forward, and a frame side discharge passage for guiding game balls discharged from the game board to a ball discharge port is formed on the back side of the frame member. When the groove and the frame side payout passage groove for guiding the game ball paid out from the ball payout device to the ball plate are formed to open rearward, and the back set board is disposed covering the back side of the frame member. A ball discharge passage is formed in which the back side discharge passage groove and the frame side discharge passage groove are aligned and opposed to each other to guide game balls discharged from the game board to a ball discharge port, and the back side discharge passage groove and the frame side discharge passage are formed. A ball dispensing passage that guides the game ball dispensed from the ball dispensing device to the ball tray with the groove aligned and facing. Made constitutes a path mechanism as.
[0012]
In the ball game machine provided with such a path mechanism, the ball discharge passage and the ball discharge passage conventionally formed on the back set board side are divided into the back side of the frame member and the front side of the back set board. When the back set board is disposed so as to cover the back side of the frame member, that is, in a normal game state, the back side discharge passage groove and the frame side discharge passage groove are aligned and opposed to each other. A discharge passage groove is formed integrally to form a ball discharge passage for guiding game balls discharged from the game board to a ball discharge port, and the back-side discharge passage groove and the frame-side discharge passage groove are aligned and opposed to each other. Are formed integrally with each other to form a ball payout passage for guiding game balls paid out from the ball payout device to a ball tray. For this reason, for example, when the passage groove is set so as to secure the same passage cross-sectional area as the conventional ball discharge passage and the ball discharge passage under a condition of a constant passage width due to the limitation of the outer frame size, the frame member The groove depth (depth) of the back side passage groove can be reduced by an amount corresponding to the groove depth of the frame side passage groove formed in the above, whereby the thickness of the back set board is reduced over a wide area to make it thin. be able to.
[0013]
In addition, by reducing the thickness of the back set board in this way, it is possible to arrange various circuit boards generally mounted on the back side of the back set board in a position more forward than in the past. Accordingly, it is possible to improve the problem of difficulty in installation on the game island, the problem of the heat radiation effect of the circuit board, the problem of the circuit configuration of the circuit board, and the like.
[0014]

Even in this case, the slider 120 can be detachably attached by moving and fixing the slider 120 according to the size of the power supply board 41. In addition, since the power supply board mounting portion 100 is formed behind the game-completed ball discharge passage 50 and the lower ball dish payout passage 70, the power supply board 41 must be disposed forward as shown in FIGS. As a result, the clearance behind the power supply board can be increased to solve the problem of the heat radiation effect of the circuit board, the problem of the circuit configuration of the circuit board, and the like. Also, if the rear end position of the circuit board is the same as the conventional one, it is possible to mount a large capacitor, etc., which has been difficult to mount due to the height of the components, thereby simplifying the circuit configuration or reducing the board area. A reduced substrate configuration is also possible.
[0084]
Further, since the slider 120 slides in front of the power supply board 41, a board mounting portion having the above-described adjustment function can be formed in an area approximately equal to the size of the power supply board 41. It is possible to configure a pachinko machine in which various circuit boards can be attached and detached with good space efficiency within the limited area and thickness.

Alternatively, a small-sized shoulder bolt may be used instead of the seat and the slider mounting screw 127 so that a disc spring washer or the like is sandwiched and tightened.
[0086]
In addition, the out ball and the safe ball discharged from the game board 20 to the back side are gathered by the ball shift cover 28 and flow down, but these game balls are discharged through each individual ball discharge passage. The same configuration and the same effect can be obtained even in a configuration in which the components are collected and a configuration in which the components are assembled along the ball discharge passage.
[0087]
【The invention's effect】
