  As described above, as a ball game machine having a game board in which a front-side game board component and a back-side game board component are respectively attached to both the front side and the back side of a rectangular plate-like board surface member, for example, a pachinko machine Machines, sparrow ball machines and arrange ball machines are widely used in games. In a pachinko machine that is a typical example of this type of ball game machine, a large number of game nails and windmills are planted on the surface side of a board member also called a veneer or a decorative board, Front side game board components such as central decorations and rail decorations are attached, and backside game board components such as a ball cover, guide display device, various circuit boards, etc. for guiding the already played balls are attached to the back side of the board members. The game board is configured. The game board is detachably accommodated in the front frame of the game machine main body, and is fixed and held in the accommodated state by a fixing lever provided on the front frame and provided for the game.

  In recent years, in order to improve the production efficiency of game boards and reduce production costs, the development of a game board manufacturing system that introduces automatic machines into the assembly line of game boards and attaches game board components has progressed. Yes. In order to cause the game board that is sequentially transported through the game board assembly line to perform the mounting operation of the game board components by an automatic machine, it is necessary to accurately position the game board that has been transported to the process. Therefore, a reference hole serving as a positioning reference for the game board is formed in the board surface member in the initial process of manufacturing the game board (reference hole arrangement process). A system configuration is adopted in which positioning is performed and various game board components are attached.

  The game board is in the form of a flat plate at the initial stage of the game board assembly line, but with the progress of the part mounting process, game board components are attached to the front and back of the board member, and the attached game components Projecting from the front and back surfaces of the board member. Therefore, in the game board assembly line, a frame-like pallet having a reference hole on the game board side and a detachable reference pin is used to position and support the game board, and the pallet is moved by a transport mechanism.

Japanese Patent No. 3351589

  By the way, in the game board of a ball game machine, since different game board components are attached to the front side and the back side of the board member, the game board assembly line is broadly divided into front side games such as winning equipment. It is composed of a front side part mounting line for mounting board component parts and a back side part mounting line for mounting back side game board component parts such as a ball cover. A series of game board assembly lines are formed by connecting the front and back component mounting lines, and a manual operation (for example, component mounting operation) stage and an automatic machine (for example, component fixing operation) stage are provided on each line. In order to allow the work to proceed efficiently even in a line configuration in which the game machines are mixed, it is preferable to attach the front game board component and the back game board component from the same direction (for example, from above). Therefore, a game board reversing device is provided between the front part mounting line and the back part mounting line so that the orientation of the gaming board is reversed, and the gaming board with the front side gaming board components attached is reversed from the same direction. It is considered appropriate to configure the game board components so that the production efficiency can be further improved. In order to reverse the front and back of the rectangular board-like game board, it is preferable to rotate the center line in the vertical or horizontal direction along the board member as an axis (reverse axis).

  However, in a game board of a ball game machine, a game area is formed in a substantially circular shape on the surface side of the board surface member, and an out port for leading out balls to the back side of the board surface member is a board surface member at the center of the lower end of the game area. It is provided through the front and rear. Therefore, if it is intended to secure a wide game area in the rectangular board member, two reference holes necessary for defining the position and angle of the game board may be provided on the upper and lower or left and right center lines of the board member. It is difficult, for example, the reference hole formed on the lower side has to be formed offset to the left or right from the center line extending vertically. Then, the reference hole at a position away from the center line will move to an axially symmetric position when the front and back of the game board are reversed. For example, an inversion axis is set on the vertical center line of the game board. When the front and back are reversed, the reference hole located on the left side of the center line before the reversal moves to the right side of the center line after the reversal.

  In this case, as a means for positioning, supporting and transporting the game board in which the position of the reference hole has moved, for example, a common base part of the pallet is used, and jigs with different reference pin positions are detachably positioned on the pallet base. The structure to transfer the game board by exchanging the jig before and after the game board reversing process, or separating the transport device in the front part mounting process and the transport device in the back part mounting process, respectively, A configuration is possible in which the game board is transported using a pallet with different reference pin positions in the transport device.

  However, in such a configuration, the game board assembling process becomes complicated, and the number of jigs and pallets having different reference pin positions may increase, resulting in confusion at the manufacturing site. In addition, in the configuration for exchanging jigs, even if a game board reversing device is introduced to automate the reversing work, it is difficult to improve the production efficiency of the entire assembly line because it takes time to replace the jig to be performed at the same time. . In addition, in the configuration in which the transfer device is separated before and after the game board reversing device, the assembly line configuration is complicated, and in addition, the front side transfer device is carried into the game board reversing device and the game board reversing device is connected to the rear back side transfer device. The game board reversing device requires a loading function and an unloading function, and further requires synchronized control of the front and rear transfer devices, making the system configuration of the entire game board assembly line complicated. To do.

  Furthermore, even if it is configured to position and support the game board that is turned upside down by any one of the above means, it is not possible to adopt a game part that hides the reference hole formed in the board surface member, There remains a problem that selection of game parts and expansion of the game area are limited in relation to the reference hole.
