Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a control device for a game machine used for exchanging game contents. 2. Description of the Related Art In recent years, with the spread of microcomputers, complicated and sophisticated games have become possible, and diversification of games has been desired. Therefore, game machines have new game contents in a certain cycle. Will be replaced. This exchange is not performed for all of the gaming machines for economic reasons, and a part of each component is replaced. Next, replacement of the above-mentioned gaming machine will be described below by taking a pachinko machine as an example. Even if the pachinko machine has a different game content, in other words, a different model, the basic device configuration and the game procedure do not change, and the mechanical parts such as a ball hitting device and a prize ball payout device are rarely exchanged. In other words, pachinko machines are replaced by a game board called a gauge board and electronic control system components (hereinafter, referred to as “gauge board”) for executing the game procedure.
Only the control device constituted by “electronic parts”) needs to be replaced. Incidentally, the electronic components of the above control device are
As shown in the figure, a common electronic component that constitutes a circuit that can be commonly used for a replaced pachinko machine such as the CPU 30 and is mounted on a board, and an R that stores a unique game procedure (program)
It is classified as a non-common electronic component that constitutes a circuit that cannot be commonly used, such as OM20. For this reason, it is necessary to replace all game boards with new ones for design reasons, but it is economically desirable to replace only non-common electronic parts. The above-mentioned common electronic components include a CPU 30, a RA
M31, ROM 32 storing a basic program, matching circuit 3 for performing basic matching between a mechanical unit (not shown) and CPU 30
3. There are a power supply circuit 34, an audio signal generation circuit 28 for generating basic audio, a resistor, and the like. On the other hand, non-common electronic components include a ROM storing a unique program and data such as a game procedure of a new game board.
20, a RAM 37 for expanding the storage capacity, the mechanism unit and the CPU 30
There is a matching circuit 38 for performing unique matching with the audio signal, an audio signal generating circuit 35 for generating a unique sound, a circuit for controlling a unique mechanism, a resistor, and the like. In order to newly replace only the non-common electronic components among these electronic components, the old game board is removed from the installation location of the pachinko machine, and the common electronic components of the old game board are removed. Then, the removed common component is mounted on a new game board on which non-common electronic components are previously mounted, and the new game board is re-installed together with these electronic components at the installation location. That is, in the electronic components of the pachinko machine, the common electronic components of the old game board are reused, and only the non-common electronic components are replaced. After this re-installation, the inspection of the electronic system between the mechanical unit and the electronic component and the alignment between the mechanical unit and the electronic component are inspected, and the replacement of the pachinko machine is completed. The replacement of electronic components related to this pachinko machine has been performed in units of two types of plural boards in which electronic components are classified and mounted according to common or non-common components. As described above, an economic problem occurs when all the electronic components (control devices) are replaced together with the game board, but when only the non-common electronic components are replaced, At present, a single board on which all the electronic components for the new game board are mounted is mounted on the new game board and the old game board is replaced with the new game board because of the following problems. First, after the replacement work and after the replacement work, various inspections concerning the mechanism of the gaming machine, the electronic components, and the matching between the two must be performed, and this inspection work requires many man-hours. Further, since the board is separated into common electronic parts and non-common electronic parts, restrictions on board design such as signal line design and circuit design of the board are increased. For this reason, a lot of time is required for replacing the pachinko machine and developing the board, so that the working efficiency is poor. Second, the common electronic component and the non-common electronic component are separately mounted on a plurality of boards, and each of these boards is usually connected to a control circuit, each board, etc. via a connector. I have. As a result, as shown in FIG. 8, the number of connectors increases, so that the number of connection points increases as compared with the case where each electronic component is mounted on a single substrate, and the possibility of occurrence of defective products due to poor contact due to vibration or the like increases. Therefore, the running cost increases during production, and the failure rate tends to increase during the game (operation) of the pachinko machine, so that the product reliability decreases. In order to suppress the increase in the running cost and the decrease in the reliability of the product, there is a method of connecting the connecting portion of the connector by soldering. However, this soldering work is performed when the electronic components are mounted on the plurality of substrates. In addition, it must be performed when connecting each substrate. For this reason, the number of work steps increases. Third, the common electronic component can be used in all pachinko machines, and the ROM can be used in all pachinko machines by changing the written contents to predetermined ones. However, when the collected common electronic components and ROM are reused, it is necessary to sufficiently inspect the basic performance of these electronic components, so that much time is required and the reliability of the electronic components is reduced. Fourth, since these boards are formed by separating a conventional single board and integrally forming a connector, each board is smaller than the conventional board. This increases the possibility of fraudulent acts such as changing the circuit on the board and the contents of the ROM due to easy attachment and detachment. Therefore, the present invention provides a gaming machine which is easy and reliable to exchange and has a countermeasure for preventing wrongdoing. According to the present invention, there is provided a pachinko machine in which the game board 19 is separable from the pachinko machine main body. , A common circuit 8 and a non-common circuit 9 controlled by the CPU, and a prize ball payout device 6 and a hitting device 7 commonly used for a plurality of types of pachinko machines are provided.

And an audio signal generation circuit 35 for generating audio unique to a plurality of models. In the present invention, the control device of the game machine is constituted as described above, and the game board 19 is separable from the pachinko machine main body. On the substrate provided on the back of the pachinko machine, a common circuit 8 that can be used in common for a plurality of models of pachinko machines having different specifications and a non-common circuit 9 that differs depending on the model are provided.

For this reason, first, the man-hours required for the replacement work and various inspections after the replacement work are shortened, and restrictions on board design such as signal line design and circuit design of the board are relaxed. Second, since a connector is no longer used to connect the common circuit and the non-common circuit, the possibility of defective products due to poor contact due to vibration or the like is extremely reduced. As a result, the running cost is reduced during production, and the failure rate is reduced during the game (operation) of the gaming machine, so that the product reliability is improved. Third, since it becomes difficult to perform an illegal operation on an integrated circuit, the integrated circuit has a sufficient effect to prevent illegal operations such as rewriting of a program and processing of hardware (substrate, electronic component).
