PROBLEM TO BE SOLVED: To execute proper alignment of a transfer sheet for a fixed mold even if the vicinity of a width-direction mark of the transfer sheet for a fixed mold is deformed in a double-sided decoration injection molding machine.SOLUTION: A sheet width sensor 60 has a light-emitting body and a light-receiving body. The sheet width sensor is configured such that a transfer sheet for a fixed mold is positioned between the light-emitting body and the light-receiving body. The sheet width sensor 60 has a light-emitting-side flat plate 62 whose one surface is a light-emitting-side flat sheet surface 64, and a light-receiving-side flat plate 72 whose one surface is a light-receiving-side flat sheet surface 74. The light-emitting-side flat sheet surface 64 and the light-receiving-side flat sheet surface 74 are held in parallel to each other. The interval between the light-emitting-side flat sheet surface and the light-receiving-side flat sheet surface is held within a range of ≥0.1 and ≤1.5 mm. The sheet width sensor detects a width-direction mark formed on the transfer sheet for a fixed mold. |
