Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an electrical control device for games, and more particularly, for example, in a gaming machine capable of developing a pachinko game, which is detachably equipped in a predetermined part of the same machine and controls electrical control processing. It relates to the device.
[0002]
[Prior art]
For example, in a pachinko machine or an arrangement ball machine, which is one of the representative examples of pachinko gaming machines, various prize-winning equipment and winning equipment as game parts are arranged on the game board set in the machine, while electronic control parts An electronic control game that includes sound effects and decoration lights that match the pachinko game that is deployed in the game board, with detection switches, electromagnetic solenoids, lamps, etc. It can come out. Each of these electrical components is intensively connected to an electronic control device (generally also referred to as a main board or a game board) in which a genuine control board suitable for each electronic control game is housed in a protective case. The operation is controlled according to the respective movable conditions, mainly at the time of setting conditions that are generated and established during the game or in the special gaming state.
[0003]
In the electric control device, the protective case is composed of a plate-like member and a cover-like member that are separated from each other, and the circuit board is set in the plate-like member and the cover-like member so that they can be handled in a single unit. It is configured as a unit of units and is separated from the various components of the gaming machine. In the implementation, it is assumed that the machine is installed in the final process part of the production line of the gaming machine, or is installed after the gaming machine is installed in the gaming store after being separated from the gaming machine in advance. 1 is installed at a predetermined part of the mechanism set panel on the back side of the front frame and is connected to various electric parts. Further, in the electric control device, since the protective case is a molded member made of synthetic resin, it is necessary to take countermeasures against electromagnetic waves with respect to the circuit board. Therefore, the protective case is molded from a conductive material such as a tin material or a tin material. The type of the shield plate is used in combination with the inside of the protective case.
[0004]
[Problems to be solved by the invention]
By the way, in the electric control device used for the pachinko machine, the dish-shaped member and the anti-tampering measure for preventing unauthorized modification / change on the premise that it is normally used with proper control contents (software program contents) The cover-like member is molded with a transparent resin, and it is obliged to make the electronic components on the front side and the circuit pattern on the back side of the circuit board built in the protective case easily visible from the outside. It is now possible to discover removal / replacement and unauthorized modification / replacement of electronic components. However, the shield plate is made of an opaque material, and is positioned close to the back surface of the circuit board between the dish-like member and the circuit board in the protective case. Therefore, in the electric control device incorporating the circuit board and the shielding protection member, it is impossible to visually recognize the circuit pattern on the back surface of the circuit board even if the entire protective case is formed of a transparent member. That is, when the circuit pattern inspection of the circuit board built in the protective case is performed, the protective member must be opened by removing the cover-like member from the dish-like member. There has been a problem in that the seal stamp affixed to the assembly matching portion with the cover-like member has to be peeled off. Further, even if the seal stamp paper is peeled off and the protective case is opened, the screws for fixing the circuit board to the dish-like member must be removed, and the inspection work of the circuit pattern on the circuit board is very troublesome and It was cumbersome and time consuming.
