The transfer support 64 is provided with a transfer pad 11, an electric heater 12 as an example of a heating device, and a pair of swinging arms 82, 82 to allow the guide rollers 8 and 81 to swing freely. The sensor is brought into contact with the transfer pad u to control the surface temperature. The transfer pad 11 is often rotated in advance to prevent unevenness in the surface temperature of the transfer pad 11. The rotation of the transfer pad i i is performed by a motor 85 under the driving of a belt and a belt driving a pulley. The guide roller 81 mounted on the transfer pad 11 is configured as follows: it can be moved in and out of the transfer roller 11 by swinging the arm 82; when the light guide plate 41 is connected to the transfer roller 11 through the transfer material (proceeding) When transferring), it moves backward (left direction in FIG. 9), and moves forward when it is not connected to the light guide plate 41 (right direction in FIG. 9). This is because the transfer material 14 leaves the transfer pad U when not transferring. This prevents the transfer material from being damaged by the heat of the transfer pad u. The take-up side roll 73 is used to hold a roller-like new transfer material 14 and supplies the new transfer material 14 to the transfer pad 14. Therefore, the transfer material 4 can be rolled back from either the take-up side roll 73 or the take-up side roll 74 so that the new transfer material 14 does not move relative to each other on the side of the light guide plate 41 during the transfer, and The new transfer material 14 is pushed from the back side to the side of the light guide plate 41 by the transfer pad 11.
