ABSTRACT:
A file for gripping sheets of the invention is formed of an elongated base member and a plurality of gripping devices attached to the base member. The base member is formed of upper and lower portions, a back portion situated between the upper and lower portions at a back side, and upper and lower guide members fixed to the upper and lower portions to face to each other at a front side. Each guide member diagonally extends toward the back portion. Each gripping device includes upper and lower frictional members with elasticity. The upper frictional member is fixed to the upper portion, and the lower frictional member is fixed to the lower portion to face to each other. When the sheets are inserted between the upper and lower portions, the sheets are guided by the guide members and are frictionally retained between the frictional members.
