Description

[Detailed Description of the Invention] Industrial Application Field The present invention prints necessary information on continuous paper, cuts it to form paper pieces such as labels of a predetermined length, and stores these paper pieces in a stacker. The present invention relates to a printer with a paper conveying device.

Conventional technology In general, in printers that cut continuous paper with a cutter to form pieces of paper such as labels of a predetermined size, the feed rate of the paper pieces cut by the cutter is faster than the feeding speed of the continuous paper inside the main body case in which the printing section is installed. The feed speed is set to be fast. This prevents the cut pieces of paper from overlapping each other, but the purpose is to stack and store a large number of pieces of paper in the order in which they were cut.

In this storage method, cut pieces of paper are sequentially fed onto an inclined slide, and the pieces of paper that slide down the slide are stacked on a tray or an equivalent table.

Problems to be Solved by the Invention When cut pieces of paper are fed onto a slide and allowed to slide down, the orientation of the cut pieces of paper tends to change during conveyance, or the order of the pieces is easily thrown out of order. is difficult.

In addition, it is not possible to stack the supports on the stand by natural falling.
Even if the order is not out of order, the stacking state is not constant,
It must be handled with care when taking it out.

Means for Solving the Problem A main body case is provided which has a built-in printing unit for printing on continuous paper, a cutter is provided in proximity to the continuous paper output port of this main body case, and the continuous paper is fed by being connected to this cutter. An endless belt-like belt that rotates at a feed rate faster than the cutting speed is provided, and a flat holding portion having a presser plate having a flat contact surface for holding the piece of paper cut by the cutter on this belt, and a feeding direction of the piece of paper. A direction changing part for changing the direction of the paper and a pushing part for pushing the paper into the stacker having a pushing plate for pressing the paper into the belt were successively installed.

The speed of the paper pieces cut by the belt connected to the cutter is made higher than the speed of continuous paper to prevent paper pieces from overlapping during conveyance, but a presser plate with a flat contact surface is installed immediately after the cutter. Since a flat holding part is provided, the paper pieces can be sent out reliably, and furthermore, a direction changing part that changes the feeding direction of the paper pieces and a pushing part that has a pushing plate that presses the paper pieces against the belt and pushes the paper pieces into the stacker. By sequentially arranging the paper strips in sequence, the paper strips stored in the stacker are vertical, and even if a storage method is adopted in which new paper strips are sequentially press-fitted to the rear end, the paper strips can be transported reliably. It is configured so that it can be done.

An endless belt 30 having a constant width is stretched between the driven shaft 23, the driven shaft 27, and the intermediate shaft 28, 29. The moving speed of this belt 30 is set to be faster than the feeding speed of continuous paper. Further, a flat belt guide plate 31 is horizontally provided at a lower surface position of the belt 30 between the driven shaft 27 and the intermediate shaft 28, and A smoothly curved curved belt guide plate 32 is provided on the inner surface of the belt 30.

Next, a flat holding plate 34 having a flat contact surface 33 is provided on the belt 30 at the upper part of the belt guide plate 31, and vertical walls 35 on both sides of the holding plate 34 are provided.
Two support bins 36 are provided in each of the support bins 36, and these support bins 36 are biased downward by springs 37 applied to the support bins 36.

That is, a flat holding portion 39 is provided which presses the paper piece 38 cut by the cutter 7 flat with a constant pressing force.

Further, two belt rollers 40 and 41 are provided located directly above the intermediate shaft 28 and slightly behind the intermediate shaft, and a presser belt 42 is wound around these belt rollers 40 and 41. ing. The inner surface of this presser belt 42 is
