対する正確な搬送が困難になるという問題点があった。A thin and weak original 7 having a thickness of 100 μm or less may pass through a largely bent path as shown in FIG. In the case of a thick and stiff original 7, the resistance of the original while being bent and conveyed increases due to the stiffness of the original 7 and exceeds the generated torque that can be generated by a drive motor (not shown) that drives the feed roller 3. There have been problems such as malfunctions and paper jams on the path when passing through the reading unit.
In addition, when the leading end of the document 7 presses the image sensor 2 due to the stiffness of the document 7, the pressing force between the image sensor 2 and the feed roller 3 is reduced, and there is a problem in that the document tends to be unable to be conveyed. Further, in the case of a postcard or the like, the paper powder of the postcard or the like adheres to the surface of the feed roller 3 to reduce the coefficient of friction with the image sensor 2 and, in addition to the resistance on the bent conveyance path, the conveyance of the feed roller 3 There is also a problem that the force is reduced and it is difficult to accurately convey the sheet to the reading unit.

When the flapper 10 is turned in the direction of arrow N, the flapper 10 closes the outlet 6 and opens the outlet 9 as shown in FIG. 3 and 4, reference numeral 12 denotes a pressure receiving plate which supports one end of the coil spring 4 and rotates in the same direction in conjunction with the flapper 10 when the operator 11 is turned. Here, in the state shown in FIG. 3, the coil spring 4 is extended, and the pressing force for pressing the image sensor 2 against the feed roller 3 is small, but the pressing receiving plate 12 is moved to the back of the image sensor 2 as shown in FIG. When displaced, the coil spring 4 is compressed, and the pressing force for pressing the image sensor 2 against the feed roller 3 increases.

And the main body case 1 stands on the floor as shown in FIG.
The operator 11 is turned in the arrow N direction. Then, the flapper 10 opens the discharge port 9 as shown in FIG. Then, if the thick original 7b is inserted from the insertion opening 8, the thick original 7b goes straight between the image sensor 2 and the feed roller 3, and is
Is discharged from In this case, by rotating the operation element 11, the image sensor 2 and the pressure receiving plate 12 for pressing the feed roller 3 are also rotated in the same direction, and the displacement stroke of the coil spring 4 is increased as compared with the case of the M direction. The pressing force of the coil spring 4 increases. Therefore, when the original 7 is a postcard or the like, the paper dust adheres to the feed roller 3, and a decrease in the conveying force due to a decrease in the friction coefficient of the feed roller 3 can be compensated for by an increase in the pressing force.

る。As described above, according to the present invention, a document having a weak waist can be changed at a large steep angle along the feed roller by switching the document conveyance path according to the thickness of the document and the strength of the waist. A document with a strong stiffness can be transported by moving straight and straight between the image sensor and the feed roller, so that a paper jam and a defective transport of the document can be eliminated, and the document can be fed stably. In the case of originals where paper dust such as postcards adheres to the feed roller and reduces the conveying force, it is possible to increase the pressing force between the image sensor and the feed roller to secure the conveying force. A facsimile that can reliably feed the original in a small space can be realized.
