Problems solved by technology

[0005] However, in the former automatic document feeder, it is necessary to provide a stopper for each original, and in order to feed out the originals one by one from the paper feeder, a solenoid for raising the stopper is required.
Therefore, there is a problem that the structure becomes complicated and the cost increases
[0006] On the other hand, in the latter automatic paper feeder, it is necessary to carry out a troublesome work of sandwiching the plate body between the sheets.

Embodiment Construction

[0023] Embodiments of the present invention will be described below with reference to the accompanying drawings.

[0024] figure 1 with figure 2 The medicine bag printing device of this embodiment is shown. This medicine pouch printing device includes an automatic paper feeder 1 and a printing device 3 for performing predetermined printing on paper 2 fed by the automatic paper feeder 1 . Again, here, as paper 2, use the medicine bag (refer to image 3 ).

[0025] In the automatic paper feeder 1 , the paper cassettes 5 can be inserted and removed from the front of each of the storage chambers 4 formed in multiple layers in the vertical direction. Such as Figure 5 As shown, each storage chamber 4 is provided with a paper feed roller 6 that is rotationally driven by a driving device such as a motor (not shown). The paper feed roller 6 presses and abuts against the uppermost paper 2 stored in the paper cassette 5, and conveys the paper by the frictional force generated bet...

Abstract

The automatic paper feeding device of the present invention has a paper feeding roller (6) that automatically feeds a plurality of sheets of paper (2) loaded in a paper cassette (5) in a stacked state, sequentially from the topmost paper . There is a flexible sheet (16) that is placed on the paper (2) in the paper box (5) and produces a frictional force with the paper (2) that is smaller than that of the paper supply roller (6). ). Although the structure is simple, it can reliably prevent the sheets (2) from being fed out overlappingly.

Description

technical field [0001] The invention relates to an automatic paper feeding device for paper, in particular to an automatic paper feeding device for medicine bags. Background technique [0002] Conventionally, as an automatic paper feeder, for example, the following structures are known. [0003] In Japanese Patent Laid-Open No. Sho 49-67620, an automatic paper feeding device is disclosed, which is provided with a brake pad at one end of the stacked originals on the paper feed base, and the brake pad can be used to prevent one-time conveyance. In the case of 2 originals. [0004] In the Japanese Patent Laid-Open Publication No. 58-69645, an automatic paper feeding device is disclosed. It passes between overlapping papers, and the friction coefficient between the paper and the paper is smaller than that between the papers. The board body of the coefficient can prevent the paper from being fed in the state of being overlapped. [0005] However, in the former automatic docume...
