Abstract

PURPOSE:To feed a paper at the time of and after printing with automatic adjustment according to the thickness of the paper, by providing a rotary member having a rotary shaft parallel to that of a feeding roller, and supporting both ends of the rotary shaft of the rotary member slant slots for automatically varying the gap between the rotary member and the feeding roller according to the thickness of a paper. CONSTITUTION:At the time of operating a push tractor type printer paper- feeding mechanism, a paper 2 is first set to a push tractor 1. The paper 2 thus set is fed between a platen 3 and a printing mechanism 4 by a transmission mechanism, being clamped between a feeding roller 5 and a rotary member 6, and is discharged through a paper cutter 7. Bearing parts of the rotary member 6 are received in slots 8 so slanted that the gap between the feeding roller 5 and the rotary member 6 can be freely varied according to the thickness of the paper, and only the weight of the rotary member 6 is applied to the paper 2.

[Prior Art] A conventional bush tractor-type printer paper feeding mechanism is equipped with a transmission mechanism using a rotary motor, a belt, and gears. It was inserted between the vapor guide and sent out roughly along the vapor guide to the front upper part of the platen. When printing using the printing mechanism,
The structure is such that a rotating member provided at the upper part of the platen iIf is pressed against the platen side and the paper is pulled up.

[Problems to be Solved] In the conventional push-tractor type printer paper feeding mechanism described above, the rotating member installed in front of the platen is unable to properly feed both single sheets and multi-sheet sheets. In order to do this, the rotating member and the platen are adjusted to have a certain gap and are fixed.

However, if the gap between the rotating member and the platen is fixed as described in 11η, it is very difficult to properly feed both single sheets and multiple sheets of stacked sheets because the thickness of the sheets is different. is adjusted according to the feed of the cut sheet. For this reason, when a plurality of sheets of stacked paper are fed, the feeding force applied to the paper by the rotating member becomes large, resulting in a disadvantage that a feed jam (clog phenomenon) and transfer of the lower layer paper occur.

[Solving the Problems] The present invention, which solves the above problems, is a bush tractor type printer paper feeding mechanism, which includes a feed roller that feeds the paper during printing and after printing, and a feed roller that feeds the paper during printing and after printing. It is characterized by having a rotating member having parallel rotating shafts, and supporting both ends of the rotating shaft of the rotating member through an inclined elongated hole that automatically changes the gap between the paper and the paper feed roller according to the paper thickness.
