  Further, in this roll type transfer device 4, since the next game board can be preheated while the transfer film 3 is being crimped to the game board, the workability is good, and the time required for crimping the transfer film 3 is also good. Since it takes several tens of seconds, the hard coat layer 3b of a large number of game boards can be formed in a short time, and it can be easily finished neatly without causing unevenness such as irregularities. The problem that the surface is easily scratched by the contact with is solved, and the problem that it is difficult to see the symbol display device and various decorative members due to the scratch on the transparent game board is also solved. Further, by providing a pattern layer on the transfer film, the patterning process can be performed at the same time, so that the production efficiency can be further increased.

In addition, as shown in FIG. 5, another worker (a) for setting the game board 1 is arranged near the work preheating device 4a, and the transfer-processed game board 1 is taken out from the turntable 4c. By preventing the same worker from touching the fragments of the hard coat layer 3b, it is possible to prevent the fragments of the hard coat layer 3b from adhering to the untransferred game board 1. Is done. For this reason, generation | occurrence | production of the inferior goods that the fragment of the hard-coat layer 3b is pinched | interposed between the surface of the game board 1 and the hard-coat layer 3b can be prevented.
In this embodiment, the game board 1 is preheated in order to improve transferability. However, it is not always necessary to preheat, and in order to improve transferability, the surface of the game board 1 is subjected to corona discharge machining. The wetting index may be 50 (dyne, mN / m) or more.

  10 and 11 show a state where the hard coat layer 3b is transferred to the back surface of the transparent synthetic resin game board 1 with the picture layer 3d inside, by the transfer device and the transfer method. By transferring the picture layer 3d and the hard coat layer 3b to the back surface of the game board 1 in this way, the picture pattern of the picture layer 3d is seen through from the front surface of the game board 1, so that it appeals to the player's vision. It is possible to produce with a great depth. And since the pattern layer 3d is protected by the hard coat layer 3b, damage due to contact with the game ball can be prevented even in the usage mode as shown in FIG. 12, and the appearance can be maintained for a long time. .
