In recent years, as demand for pachinko gaming machines has increased, automation has been promoted as much as possible in each manufacturing process of the gaming machines. Normally, during manufacturing, the flat master board of the game board made of plywood is drilled, cell pasted, and pressed (a preliminary process for nailing, which is done before the nailing process).
The process involves making indentations in advance on the surface of the game board so that nails can be easily driven), nail driving, rail installation, accessories installation, etc., and a series of steps are performed. Due to the convenience of workers in each manufacturing process,
Between appropriate steps in the first half, an independent step (engraving step) is incorporated to add an identification mark to the game board according to the model of the pachinko game machine. by the way,
Up until now, this marking process has been done by hand, with dedicated workers adding identification marks to appropriate locations on the game board, which has caused problems in terms of time and cost. . However, despite this, it was not possible to proceed with automation because even if it were automated, as long as the process was considered as an independent process, dramatic labor savings could not be expected.

The present invention has been made in view of the above circumstances, and its purpose is to shorten manufacturing time and reduce the number of workers by making it possible to attach identification marks to appropriate locations on a pachinko game board at the same time as the hollow pressing process. An object of the present invention is to provide a method for attaching an identification symbol to a pachinko game machine, which can reduce costs and contribute to automation of the manufacturing process of pachinko game machines.
