稿ばなれ性を必要としている。2. Description of the Related Art There is a copying machine as shown in FIG. 1 as a copying machine capable of continuously automatically copying a plurality of originals. That is,
In this copying machine 1, a plurality of originals 3 are placed in a stacked manner on a document holder 2 arranged at the upper end of one side of the main body with the front side facing down, and the original holder cover is placed. 4 is rotated around one edge as shown by an arrow A in the drawing to tilt it on the platen glass 5, and in that state, a switch (not shown) is pressed to operate, so that it is provided on the back surface of the platen cover 4. The white rubber paper feed belt 6 running in the direction of the arrow B conveys the originals 3 placed on the original placing table 2 one by one from the upper side onto the original placing glass 5 each time copying is completed. It is like this. In this case, in response to the copy, the copy paper 8 or 10 housed in the copy paper cassette 7 or 11 is conveyed to the inside of the copying machine 1 and the surface of the manuscript 3 or characters or patterns are transferred. It is sent to the copy tray 9.
In the figure, reference numeral 17 is a storage tray for the originals 3 that have been copied. Such an automatic document feeder of the copying machine 1 is shown in FIG.
As shown in FIG. 2, the rotation of the two drive rollers 12 causes the paper feed belt 6 to travel to convey the original 3, and the number of rotations of the paper feed belt 6 (the number of rotations of the drive roller 12 is counted to determine the paper feed belt 6). Measure the number of rotations of 6)
Is provided at a predetermined position on the platen glass 5. In the figure, 14 is a press roll.
Further, in order to simplify the structure and reduce the cost, the stop position is not determined by the rotation speed of the paper feed belt 6, but the document stopper 1 for stopping the document 3 is used as shown in FIG.
3 is provided on the edge of the platen glass 5. The paper feed belt 6 needs a frictional force to convey the original document 3 and needs to have the originality of the original document to eject the original document 3.

2 are connected by a thread 25, the measuring gauge 22 is moved in the direction of the arrow under a certain condition, and the tensile force (F) during the movement
Was measured. Using the measured tensile force (F), the friction coefficient with respect to paper was calculated from the following formula. As the above condition, the pulling speed in the arrow direction was set to 115 mm / min.
【００２６】Ｆ＝μＮ 〔上記式において、Ｎは重鎮２０の重さである。〕F = μN [In the above formula, N is the weight of the heavy weight 20. ]

は、強度および硬度等の物性に問題がなく、しかも対紙
摩擦係数が低い。From the results shown in Tables 3 and 4, the products of Comparative Examples are not inferior in strength and hardness to the products of Examples, but have a high coefficient of friction with paper. On the other hand, the example products have no problem in physical properties such as strength and hardness, and have a low coefficient of friction with paper.
