等の不具合もなく、実用的利点が高い。According to the device configured in this manner, the original paper 2 to be used for image input is fitted into the locking portion of the sheet film 3, and held with its position regulated 6-, and then the sheet film 3 is placed on the rotating drum. By winding the paper into one end and fixing the other end, the two manuscript papers can be correctly mounted on the rotating drum 1. Furthermore, by simply positioning and loading the original paper 2 with respect to the sheet film 3, it is possible to correctly position and load the document paper 2 with respect to the rotating drum 1. Also, the positioning with respect to the sheet film 3 is very simple, as the edge of the manuscript paper 2 is placed on the sheet.
Furthermore, it is possible to accurately mount the original paper 2 and to input images correctly. Therefore, its practical advantages are very large. Further, since the sheet film 3 receives a tensile force from the spring 6 at the fixed portion at the other end, the document paper 2 sandwiched between the sheet film 3 and the rotating drum 1 is extremely stable and reliably positioned. It is maintained in the same state. Therefore, there is no risk of misalignment due to rotation of the rotary drum 1. Further, unlike the conventional method, there is no problem such as the possibility of damage to the original paper 2, and the present invention has a high practical advantage.
