Description of the Related Art Sheet-shaped members are processed in various fields such as forming a layer on the surface of a sheet-shaped member (so-called web) such as a sheet, film or foil, or adhering another sheet-shaped member. It is being appreciated. The sheet-like member is continuously supplied by the unwinding roll, is appropriately passed over the carrying roll, is transported, is processed, and is wound by the winding roll.

いるものとする。When the sheet-shaped member is conveyed, it is important to control the position in the width direction. Conventionally, the position control of the sheet-shaped member in the width direction has been performed by detecting the position of the sheet-shaped member in the width direction using a position detection device and adjusting the position of the unwinding roll in the width direction. Here, the position detection device that detects the position of the sheet-shaped member in the width direction is
The light source is arranged below (or above) the sheet-like member, and a light-receiving sensor is arranged to face the light source with the sheet-like member interposed therebetween. This device is used to receive light emitted from the light source. By reading with the sensor,
The position detection in the width direction is performed. Hereinafter, it may be simply referred to as a "sheet-shaped member position detection device", but
It means a device that detects the position of the sheet-shaped member in the width direction.

査が行われている。Further, the appearance of the sheet-shaped member is also inspected. Similar to the above position detecting device, a conventional visual inspection device is roughly composed of a light source arranged below (or above) a sheet-shaped member and a light-receiving sensor arranged to face the light source and the sheet-shaped member. A visual inspection is performed by reading light emitted from a light source and transmitted through a sheet-like member by a light receiving sensor using this apparatus.

となり、不良箇所発見の精度が低下することがあった。Conventionally, the position detecting device and the visual inspection device for the sheet-shaped member have been appropriately arranged between the adjacent conveying rolls. However, since the sheet-shaped member is conveyed at a high speed, the adjacent members are adjacent to each other. The sheet-shaped member passing between the transport rolls sometimes vibrates significantly in the vertical direction.
Therefore, in the position detection device, the light transmitted through the sheet-shaped member may be scattered by the vibration, and the position detection accuracy may decrease. Also in the visual inspection apparatus, the sheet-shaped member vibrates significantly in the vertical direction, which causes deviation or shadow of light read by the light receiving sensor, which makes it difficult to recognize the external appearance and reduces the accuracy of finding a defective portion. There was something to do.
