Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pachinko machine capable of immediately responding to various changes in a game situation. 2. Description of the Related Art As is well known, in a pachinko machine, a ball hit by a hammer travels on a board and hits a nail or is guided by a nail to enter a winning opening or not to enter a winning opening. It is a structure that enters the out ball mouth. When the ball enters the winning opening on the board, a device generally called an accessory (yakumono) operates to notify a winning. The most common of the accessories is the so-called tulip. The tulip is designed so that the petals move when the ball enters the winning opening, and this movement is driven by a solenoid provided on the back of the board. [0003] In order to manage the operation of the accessory and to smoothly operate the pachinko machine in this manner, the management of the payout of the ball at the time of winning and the replenishment for the payout of the ball. It is necessary to perform management, statistical management of winning balls and payout balls, and such management has conventionally been performed mechanically. However, recently, since it is necessary to reduce the size and weight of the back surface of the gaming machine, the control has been changed to a gaming control circuit using a microcomputer. As a result,
The game control circuit will be mounted on the back of the game board. [0004] However, in recent years, the content of games has been diversified, and the accessories and game control circuits have become larger. For this reason,
When the game control circuit is mounted in a direction parallel to the game board as in the past, the game control circuit approaches or closes to the role, reducing the degree of freedom in the arrangement configuration of the back of the game machine. Will be lost. For this reason, a case may occur in which the game control circuit must be mounted outside the back mechanism, not on the back of the game board. However, it is needless to say that when the game control circuit is exchanged with the exchange of the game board, it is more convenient to attach the game control circuit to the back surface of the game board. The present invention has been made in view of this point, and a game control circuit can be mounted on the back of a game board without approaching or overlapping with an accessory, and in a situation of a narrow pachinko hall. , To provide a structure that allows the program to be easily changed. According to the present invention, there is provided, as a means for solving the above-mentioned problems, a control circuit board provided on a back plate of a pachinko machine at a position avoiding an accessory and an out port. A rectangular control circuit board on which a ROM in which a control program is written is mounted on an installation unit. The mounting surface of the ROM is orthogonal to the back plate , and the long side is In the direction of
It is characterized by being detachably installed. [0007] With this configuration, a control program of a specification suitable for various games is formed into a control circuit, and is further appropriately selected and replaced from the back side of the game machine, so that one game machine has various characteristics. It is possible to have it, and the game will be interesting. In a pachinko hall where a number of gaming machines are arranged, the control circuit board is attached and detached in a direction perpendicular to the back surface of the gaming machines and at a position avoiding the accessory, thereby affecting adjacent gaming machines. The control circuit can be attached and detached without hindrance and without distraction.
By keeping the position away from the character, the function of the pachinko machine will not be affected at all. An embodiment of the present invention will be described below with reference to the drawings. In FIG. 1, reference numeral 1 denotes a back plate of a pachinko machine, which shows the back surface thereof. Reference numeral 2 denotes a control mechanism for the accessory provided on the board, and reference numeral 3 denotes an out ball receiving port. Various devices are further provided on the back surface, but are not shown because they are not directly related to the present invention. Back plate 1
Is provided with a box 4 in the lower corner.
Further, two cartridge insertion ports (hereinafter, simply referred to as insertion ports) 5 and 6 are formed. The cartridges 7 and 8 can be detachably connected to the insertion ports 5 and 6 in a direction orthogonal to the back plate 1. The cartridge 7 is provided with, for example, a ROM for a program for controlling an accessory.
Is provided with a ROM of a program for controlling the approach of the ball. Therefore, in the ROM of the cartridge 8, programs such as management of paying out balls at the time of winning, supply management for paying out balls, and statistical management of winning and payout balls are written. FIG. 2 is an enlarged view of the insertion opening 5 of the cartridge 7. Since this structure is completely the same for the cartridge 8, only the cartridge 7 will be described. A socket 9 is provided inside the box 4 toward the rear of the back plate 1.
Is inserted from the back of the pachinko machine in a direction orthogonal to the main body (back plate 1) of the pachinko machine. As a result, in the pachinko hall where a large number of pachinko machines are arranged, the attachment and detachment of the cartridge 7 (same for the cartridge 8) can be performed without any trouble. In FIG. 1, reference numeral 10 denotes a power supply unit. The power supply unit 10 includes the cartridge 7,
8 and to supply current to the role of the board. If the power supply unit 10 is connected when the pachinko machine is installed, it is rarely removed thereafter, so that it is detached from the side of the pachinko machine. The power supply unit 10 may be housed inside the pachinko machine main body instead of being provided separately from the pachinko machine and connected by a cord. FIG. 3 shows the internal structure of the cartridge 7. In this figure, what is indicated by reference numeral 11 is a substrate, not shown, on which a ROM in which each of the above-mentioned programs is written is mounted, and on one side thereof, a terminal plate 12 in which a number of connection terminals are juxtaposed is provided. ing. Reference numerals 13 and 14 denote side plates forming the cartridge 7 when combined.
The substrate 11 is housed inside and connected with screws 15. At the center of one end of each of the side plates 13 and 14, concave portions 13a and 14a are provided at portions corresponding to the terminal plate 12 of the substrate 11, so that the connection terminals of the terminal plate 12 face the outside. The above structure is exactly the same for the cartridge 8. The pachinko machine thus constructed is
The power from the power supply unit 10 causes the cartridges 7, 8
And the power of the accessories on the panel. By connecting the power supply unit 10 in this way,
The effect of switching noise on the ROM can be avoided, and the problem of heat and the problem of space saving can be solved simultaneously. When changing the contents of the game as needed,
For example, changing the number of winning balls when a ball enters a certain winning opening, depending on the day, even if a ball enters the winning opening, the winning ball does not come out or out, and furthermore, the number of winning balls for each winning opening is changed. When changing them, or when changing the movement of the accessory, the cartridges 7 and 8 need only be replaced. Since the replacement may be performed with the cartridges 7 and 8 in a direction orthogonal to the back plate 1, the operation is extremely simple and there is no mistake in wiring. The present invention is a pachinko machine constructed as described above, so that a game control circuit can be mounted on the back surface of a game board without approaching or overlapping with a character. In addition, the program can be easily changed in a narrow pachinko hall. In addition, a pachinko game that has been conventionally fixed to a single content can be changed to various contents very easily. Further, by installing the control circuit from the back of the pachinko machine in a direction perpendicular to the back surface of the pachinko machine, the convenience when replacing the control circuit is remarkably improved. Even in a pachinko hall where a large number of pachinko machines are arranged, the control circuit can be attached and detached without any trouble. Also, unlike the case where a program circuit is mounted on the main body of the pachinko machine, it is extremely easy to deal with a failure. Further, by providing the control circuit at a position away from the accessory, there is a feature that the function of the accessory is not affected at all.
