<< Example >> Hereinafter, an example of the present invention will be described with reference to the drawings.

The pachinko machine 1 is a so-called card type pachinko machine that uses a magnetic card that records the number of balls held by a player. As shown in FIG. 2, the pachinko machine 1 has a glass door frame 1a and a front plate 1b provided on a front frame 1c so as to be freely opened and closed. On the front surface of the front frame 1c, a card processing device 2 provided with a magnetic card insertion port 2a and a discharge port 2b, a ball number display section 3 for displaying the number of balls held by the player, and a magnetic card There are provided amount select buttons 4, 4, 4 for selecting an amount of money to be used from among, a settlement button 5 for inputting the end of the game, an operation handle 6 of the hitting ball firing device S described later, and the like.

On the back of the pachinko machine 1, as shown in FIG.
An upper game plate 7a, which is detachably fitted between the side frames 1d, 1d integral with 1c, and has a game part formed on the front surface, and the front frame 1c side so as to contact the lower edge of the upper game plate 7a. A fixed lower game board 7b is provided. Further, a mechanism plate 8 is installed so as to overlap the entire back surface of the upper game plate 7a and the upper surface of the back surface of the lower game plate 7b, and is attached to the upper and lower game plates 7a and 7b so as to be freely opened and closed. A collecting gutter 8a formed on the mechanism plate 8 for collecting a winning ball and an out ball, a ball control device 9 installed above the collecting gutter 8a, and a mounting base 10 screwed to the back of the front frame 1c of the pachinko machine 1. The installed ball launcher S
Is provided.

As shown in FIG. 1, the ball launching device S has a ball launching component group 11 and a ball supply device 12 integrally mounted on a single mounting base 10.

Here, the part group 11 for launching a ball is the operation handle 6
A pulley 6b fixed to the tip of a rotating shaft 6a of the operation handle 6;
A firing motor 14 for repeatedly rocking the hitting hammer 13 via a cam 14a; a spring 15 for pulling the hitting hammer 13 in a hitting direction; and a spring force adjusting member 16 for locking one end of the spring 15
And a string connecting the spring force adjusting member 16 and the pulley 6b.
It is a collective term for 17 mag. However, the hit ball firing component group 11 does not need to include all of these components, and for example, a pachinko machine in which the firing motor 14 is fixed to the front frame 1c may not include the firing motor 14. That is,
The main components that can be set on the mounting base 10 may be arbitrarily selected according to the type of the pachinko machine.

The ball supply device 12 is mounted on the back side of an upper plate portion 10a extending in a crank shape with the mounting base 10 facing upward, and is arranged side by side with the lower game board 7b. Note that a firing rail 18 is fixed to the front surface of the upper plate portion 10a. The ball supply device 12 opens a pachinko ball supply port 12b and a delivery port 12c in the box-shaped cover 12a, and connects the supply port 12b to the ball exit 8b of the collecting gutter 8a of the mechanism plate 8; To the firing portion 18a of the firing rail 18.
The internal structure of the ball supply device 12 is arbitrarily selected from those currently in use.
It incorporates a ball feed solenoid (not shown) that operates in synchronization with the swinging operation of the thirteen. In order to synchronize the solenoid with the swinging motion of the ball hammer 13, the cam 14a
An optical sensor 20 that is turned ON immediately after the user moves away from 3 is installed on the mounting base 10 so as to face the cam 14a, and the solenoid is operated by an ON signal of the sensor 20. In addition to the ball feed solenoid, a ball feed member, which is most commonly used in the art and is supported in a ball feeder 12 so as to be capable of seesaw operation, is used as the ball hammer. 13 and mechanically linked to the ball hammer 13
In response to the swing, the ball feeding member is operated to send out the pachinko balls, or a device using an electric motor is conceivable.

If the ball supply device 12 is provided at a position side by side with the lower game board 7b as described above, the most rational arrangement for integrating the ball supply device 12 with the mounting base 10 is obtained.

Further, in the present embodiment, the starting end of the firing rail 18 is fixed by using one surface of the upper plate portion 10a of the mounting base 10. The ball supply device 1 is disposed on the front side of the portion 10a.
It is also possible to make the front surface of 2 come into contact with the firing rail 18, and to mount the firing rail 18 using one surface of the ball supply device 12. Another possible possibility is that, in the present embodiment, the lower game plate 7b is formed shorter than usual in order to provide the ball supply device 12, as has been already described. However, as shown in FIG. The game board 7b may have the same shape as before, and the firing rail 18 may be directly attached to the surface of the lower game board 7b, and the ball supply device 12 may be brought into contact with the back surface of the lower game board 7b. . In this case,
The lower game board 7 communicates with the outlet 12c of the ball supply device 12
It is necessary to make a through hole 19 in b.

In addition, reference numeral 21 in the drawing denotes a guide plate provided upright between the front plate 1b and the firing rail 18. The guide plate 21 is for preventing the pachinko ball from deviating from the orbit. The guide plate 21 is formed of a transparent member, which is convenient in the case where a window is provided on the front plate 1b to view the emission unit 18a.

In this embodiment, the ball control device 9 is connected to the mechanical plate 8.
Are separately provided on the back surface of the mechanism plate 8.
May be provided integrally with the game control device 22 provided on the back surface of the card processing device 2 or the card processing device 2.

Next, the operation of the pachinko machine 1 shown in the present embodiment will be described.

When the player inserts the magnetic card into the card processing device 2, the ball holding data recorded on the magnetic card is read into the attached ball control device 9. Then, when the player selects the amount select button 4, the held ball corresponding to the amount is withdrawn from the magnetic card, and the number of balls that can be fired is displayed on the ball number display section 3.

Then, when the player touches the operation handle 6, the firing motor 14 is activated, and the hitting hammer 13 swings repeatedly. The ball supply device 12 operates in synchronization with the swing of the hitting hammer 13, and sends the pachinko balls one by one to the firing portion 18a. The ball feeding solenoid of the ball supply device 12 is controlled by the ball control device 9 and stops when the ball holding data of the player becomes "0".

The pachinko ball sent out from the ball supply device 12
It is launched by 13 and is sent from the firing rail 18 along the guide rail to the game area of the upper game board 7a. In this state, “1” is subtracted from the held ball data of the ball control device 9.

Then, when the pachinko ball wins the winning ball device, a value corresponding to the number of premium balls is added to the holding ball data of the ball control device 9 by a signal from a detector provided individually in the winning ball device.

In addition, the winning ball thus won and the out ball that does not win flow into the collecting gutter 8a and join. As described above, the ball outlet 8b of the collecting gutter 8a is connected to the supply port 12b of the ball supply device 12.
The pachinko ball that has been hit once is sent again to the firing portion 18a and circulates.

The pachinko machine 1 to which the present invention is applied is considered to be most effective in a circulating ball system using a magnetic card as described above. However, the present invention is not limited to this. Is also applicable. That is, in the case of a normal pachinko machine, since the pachinko balls are supplied to the ball supply device 12 from the ball plate on the front plate 1b side of the pachinko machine, the gap between the ball plate and the supply port 12b of the ball supply device 12 is provided. A connecting gutter or a mounting
10 is formed in a flat plate shape, and a ball supply device 12 is installed on the upper protruding portion of the mounting base 10 toward the firing rail 18 side, and the ball supply device 12 and a ball plate 23 on the front plate 1b side are connected to each other. The pachinko balls may be supplied from above the firing rail 18 by connecting them at 24.

<< Effects of the Invention >> As described above, according to the hitting ball launching device of the present invention, the components for hitting launching and the ball supply device are collectively installed and integrated on the mounting base, thereby simplifying the assembly process of the pachinko machine. In addition, since the work can be decentralized such as utilizing subcontracting, work efficiency can be improved. In addition, the positioning between the ball launching component group and the ball supply device becomes accurate, and the operation accuracy of the ball launching device is improved. Furthermore,
Since the mounting base is separate from the lower game board, the hitting and launching device can be attached and detached even while the upper game board is mounted, so that maintenance such as repair is facilitated.
