Accordingly, the operation function of the elastic auxiliary member 30 is different from that of a conventional holding a member which clips papers by a plate spring.
In the present embodiment, the plain-like elastic auxiliary member 30 that is bent along the fixed portion 21 and the inward inclination portion 25 is attached in a region formed by the inner surface of the fixed portion 21 in the holding piece 20 and the inward inclination portion 25 extending from the connection top portion 23a to the holding end portion 24 while inclined to the side of the insertion direction.
The elastic auxiliary member 30 is formed with a thin plate of a steel product, such as an SK material and a stainless steel, with a thickness of about 0.1 mm. The elastic auxiliary member 30 is provided with a base plate portion 31 along the inner surface of the fixed portion 21 in the holding piece 20, an inclination portion 32 bent along the inward inclination portion 25 in the middle portion of the base plate portion 31 in the width direction, and protruding portions 33 and 34= which are located at the both ends-of the base plate portion 31 in the width direction and are extending from the base plate portion 31 to the side of the inserting. slot as they are. The movement of the holding portion 23 of the elastic auxiliary member 30 may be regulated to the extent to that the return force is added, in other words, a resistance force by the elastic auxiliary member 30, namely, a.spring force can be appropriately set by the thickness of the above-described thin plate, and the width and the length of the inclination portion 32.
Then, the above-described elastic auxiliary member 30 is fixed to the fixed portion 21 using an adhesive and the like in the base plate portion 31 along the inner surface of the fixed portion 21 of the holding piece 20, and at this time, the protruding portions 33 and 34 at the both ends the elastic auxiliary member 30 in the width direction are inserted into the notch portions 23b of the connection top portion 23a in the holding portion 23 for fixing.
Then, the elastic auxiliary member 30 which regulates the movement of the above-described holding portion 23 for adding a return force is attached to the paper holder 1. The elastic auxiliary member 30 functions by contact with the holding portion 23, and is different from a member, which directly holds papers in a point that the elastic auxiliary member 30 does not =

Then, when the papers are inserted from the inserting slot 19, the holding end portion 24 is pushed up by the inserted papers, and the holding portion 23 of the holding piece 20 is rotated in the paper insertion direction as a pendulum as shown by a arrow in FIG. 1; using the connection top portion 23a as a fulcrum.
When the insertion and movement of the papers is stopped, the papers can be clipped by the return force of the holding portion 23, using the frictional force between the holding end portion 24 and the bottom portion 11 of the case 10. Though the elastic auxiliary-member 30 regulates the movement of the holding portion to add the return force, the pendulum operation of the above-described holding portion 23 is not prevented, and is kept as it is. That is, there is a function by which the position of the holding portion 23 in relation to the fixed portion 21 is always kept at a predetermined position. Accordingly, when the holding force by the holding portion 23 is insufficient, the insufficiency is corrected, reduction in paper holding force caused by shrinkage of the holding portion 23 due to storage and repeated use can-be prevented, and the inserted papers can be always held by an appropriate force.
When pulling out the papers, the frictional force between the holding and portion 24 and the bottom portion 11 of the -case 10. generates resistance in the pulling-out to prevent the papers from carelessly being pulled out. When the papers are pulled out by a force larger than the frictional force, or are horizontally sled, the papers can be easily pulled out.
