Abstract

PURPOSE:To make the conveyance of paper sheets stabilizable, by installing a guide, making these paper sheets and a direction member contact with each other, and another guide, preventing a horizontal end of the friction member from being damaged, both in and around this friction member, after a direction of these conveyed paper sheets is changed and the angle with the friction member is made smaller. CONSTITUTION:The guide 10 installed in a tongue piece type friction device 4 is smooth ness in the surface, whereby a subsequent forward direction of paper sheets 2 being so far conveyed is changed a direction going along the guide 10. In consequence, each front end of these paper sheets 2 can be passed through between a paper feed roller 1 and the tongue piece friction device without biting into a friction member. And, at both sides of the tongue piece type friction member 4, there is provided with a side guide 11, which protects the friction member 5, therefore even these paper sheets 2 being conveyed have any out-of-plane deformation, the side guide 11 large in hardness protects the friction member 5, so that this friction member 5 well not receive any damage by the front end 7 of these paper sheets 2. Consequently, such a fear that each front end of these paper sheets 2 might be affected by scratches due to the damage is thus preventable.
