Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a pachinko machine that allows a player to play pachinko while viewing images on a cathode ray tube.

As is well known, the pachinko machine 1 includes a peripheral frame 2, a front frame 3 which is pivoted on one side on the front surface of the peripheral frame 2 and can be opened and closed, and a window hole 4 in the front frame 3.
The main components are a glass frame 5 that can be opened and closed freely, and a game board 6 that is provided on the back side of the front frame 3 to cover the window hole 4.

The game board 6 is attached to the back side of the front frame 3 via the middle crosspiece T, and the game section 8 provided on the front side of the game board 6 is located in the window hole 4 and covered by the glass plate of the glass frame 5. . In the conventional pachinko machine, players only play the game while watching the balls flow down the gaming section 8, so there is little variety and it is not possible to sufficiently increase the interest of the pachinko game.

Therefore, according to the present invention, a cathode ray tube is installed on the back side of a pachinko machine, and pachinko can be played while viewing the screen of the cathode ray tube, thereby sufficiently increasing the interest of the game.

However, there are various problems when attaching the cathode ray tube to the back of the game board.

That is, since players sometimes hit the glass plate, if it was directly attached to the game board, it would cause vibrations to be applied to the cathode ray tube, which could cause damage to the electrical system.Also, as mentioned above, the game board 6 is attached to the front frame 3, and the front frame 3
can be opened and closed with respect to the peripheral frame 2, and the prize ball ejection mechanism, out ball processing mechanism, etc. on the back of the game board can be inspected and repaired, so if the cathode ray tube is attached to the back of the game board, when opening and closing the front frame 3 Wiring becomes a problem. Furthermore, in a separable pachinko machine in which the game board is detachable from the front frame, the cathode ray tube must be attached and removed every time the game board is replaced. Moreover, the most problematic thing is that the back of the game board has a prize ball ejection mechanism, an out ball processing mechanism, a winning ball guide mechanism,
Because it is equipped with complex mechanisms such as a flavor storage mechanism,
It is virtually impossible to place a television receiver at the player's eye position. Therefore, in the present invention, a mounting frame is placed horizontally on the peripheral frame 2, and a cathode ray tube is attached to the mounting frame so that the image portion of the cathode ray tube faces the game board.

The embodiment shown in the drawings shows the simplest and most practical structure, in which the mounting frame 9 fixed to the peripheral frame 2 has left and right side frames 10,
10, and upper and lower horizontal attachments 11, 11 installed between both side frames.

Each side frame 10 has a contact piece 1 in contact with the back side of the vertical member 2' of the peripheral frame 2.
2 on one side, and leg pieces 13, 13 are provided at the tip of the contact piece 12 in contact with the outer surface of the vertical member 2'. This side frame 10 is connected to the surrounding frame 2
When the contact pieces 12 are placed on the back side of the vertical member 2' and the leg pieces 13 are placed on the outer surface of the vertical member 2' and fixed with screws or the like, the side frame 10 will move toward the back side of the pachinko machine. Installed to extend. Then, vertical holes 14, 14 are bored under the soil at the extending end of the side frame 10. On the other hand, the horizontal member 11 described above
has a horizontal length that is almost the same as the interval between the vertical members 2' and 2' of the peripheral frame 2, and has an L-shaped cross section to increase strength, and a receiving piece 15 is bent and formed on each edge. Further, a support piece 16 is provided horizontally in the middle of the length, and holes 17, 17 are bored on the left and right sides of the support piece 16. Therefore, the side frame 10 is connected to each vertical member 2' of the peripheral frame 2 as described above.
When the horizontal members 11 are arranged vertically in the space between the frames 10 on both sides, the small holes of the receiving pieces 15 and the vertical holes 14 are aligned, and they are fixed with bolts, etc., the mounting frame 9 is attached to the back side of the peripheral frame 2. can be assembled. The television receiver 18 has a circuit portion 19 and a cathode ray tube portion 20 protruding forward from the circuit portion 19.
At the same time, the cathode ray tube portion 20 is directed toward the game board 6 from the space between the two horizontal members 11, 11, and the support piece 1 is
The circuit portion 19 is fixed with bolts passed through each hole 17 of 6. Therefore, the television receiver 18 is firmly held by the mounting frame 9, and the image portion of the cathode ray tube faces the game board 6.

On the other hand, the game board 6 has a through hole 6 in the part where the cathode ray tube is located.
A through hole 6' is opened and covered with a transparent plate or a magnifying lens, and a through hole 6' is provided in the back mechanism of the game board so as to be large enough to allow the image area to be seen.

In particular, since the back side of the game board 6 where the cathode ray tube is located has the frame 65 of the above-mentioned back mechanism, the same hole as the through hole 6' may be opened in the frame 6''.
The image part can be made to face the surface of the game board 6, and the player can play pachinko while viewing the image.
Although the present invention is constructed as described above, the following points should be taken into consideration in actual manufacture.

First, since the television receiver mechanism can be divided into a tuned detection section and an image receiver, the television receiver 18 attached to each pachinko machine has only the image receiver. Then, a tuned detection section is installed in the management room in a corner of the game parlor, and the output of the tuned detection section is electrically connected to the image receiving section of each pachinko machine using a branch. It can be made small, and image switching can be managed from the control room. However, each television receiver may have a tuned detection section and an image receiving section.

Secondly, the switch mechanism of the television receiver may be set to ON in connection with the operation of the pachinko game.

For example, in the case of a pachinko machine that uses a motor to fire balls, if the switch mechanism is set to 0N at the same time as the motor is driven, the television receiver will not operate when the pachinko machine is not in use, thereby consuming unnecessary power. Never. Furthermore, it is possible to prevent people from playing pachinko only for the purpose of watching the television receiver.
Thirdly, between the peripheral frame 2 and the side frame 10 or between the side frame 10 and the cross member 11
It is advisable to interpose an elastic material such as synthetic rubber or synthetic resin as a backing between the glass frame and the front frame to prevent vibrations or shocks from being transmitted to the television receiver. In this way, the electrical system of the television receiver is less likely to be disturbed and can withstand long-term use.
Fourth, the mounting frame 9 is constructed in an assembled manner by the side frame 10 and the cross member 11 for ease of manufacture, ease of transportation, and ease of adjustment due to differences in shape when installing the television receiver. This is to satisfy. Therefore, the mounting frame can be integrally molded and attached to the peripheral frame, and such a structure becomes even simpler.

As is clear from the above, according to the present invention, the cathode ray tube is attached to the mounting frame horizontally suspended on the surrounding frame, so when the glass frame or front frame is opened or closed, the cathode ray tube must be removed or special wiring must be installed. No consideration is required, and the cathode ray tube can be used as is when replacing pachinko machines or game boards at game parlors.

Furthermore, there is no need to install a cathode ray tube to the pachinko machine at a factory, and it can be easily assembled at a game parlor, making it highly practical and effective.

Further, in the present invention, since the cathode ray tube is attached to the mounting frame on the back side of the peripheral frame, even if a player hits the glass plate, it is not easily affected by vibrations, and has high vibration resistance.
