れるようになっている。2. Description of the Related Art In a conventional automatic paper feed unit adjusting mechanism, as shown in FIG. 4, a main roller 1 and a return roller 2 are pressed by rotating a frame 6 counterclockwise by a spring 5 around a fulcrum 3. , Apply pressure. If it is desired to increase the pressure of the return roller 2, a higher pressure can be applied by changing the attachment device at one end of the spring 5 from the low pressure pin 8 to the high pressure pin 9.

る。SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention separates a paper guide for setting a document, a main roller for feeding the document, and a document arranged facing the main roller one by one. The automatic feed unit adjusting mechanism includes a return roller for feeding, a frame of the return roller, a fulcrum of the frame, a spring that applies pressure to the return roller, and a pressure lever that changes the pressure of the spring.

る。In FIG. 1 or FIG. 2, when an original is set on the paper guide 7, the main roller 1 is rotated to the right to feed the original, and the return roller 2 is rotated to the right to make the original 1
Separated one by one. The pressing method of the return roller 2 is such that the frame 6 is rotatably supported by the fulcrum 3 and the pressing force is low when the pressure lever 4 is positioned in a substantially horizontal state as shown in FIG. When the pressure lever 4 is vertically positioned, the pressing force is high. This switching is performed by rotating the pressure lever 4. The operation is to rotate the pressure lever 4 back and forth as shown in FIG.

という効果を奏する。As described above, according to the present invention, the pressure lever is rotated to change the direction in which the spring exerts a force on the frame to adjust the pressing force of the main roller and the return roller. The paper unit adjusting mechanism is compact, and it is possible to easily adjust from the outside.
