Description

[Detailed Description of the Invention] This invention relates to a recording paper issuing device for a printer in, for example, a register or the like.

At registers, etc., people are often seen grasping the recording paper even before it is cut out as a receipt due to the desire to quickly give the receipt to the customer.
In this case, one end of the recording paper is pressed down, causing it to become loose in the printing area, causing a paper jam. Furthermore, even if the recording paper is pulled in the width direction, the recording paper will wrinkle and cause a paper jam. On the other hand, if the recording paper is cut with a cutter and left unattended for other operations, there is a drawback that the receipt may fall inside or outside or be blown away by the wind.
A similar problem exists when issuing calculation paper using a computer.

This invention was made in view of the above points, and the object is to provide a recording paper issuing device for a printer that can prevent paper jams and falling of cut recording paper.

This idea is based on the idea that the recording paper that is sent upward from the printing section through the cutting section is guided and pulled out by a paper holder while being tilted with respect to the path from the printing section to the cutting section, and the pulled out recording paper is held down. The recording paper is loosened between the cutting section and the paper holder, and the paper holder restrains the movement of the recording paper in the width direction, thus preventing paper jams in the narrow path before the cutting section. By tilting the paper holder diagonally upward, the frictional force between the paper holder and the recording paper is increased to prevent the cut recording paper from slipping into the interior, and even if it does slip down, there is no path between before and after the cut. Because it bends, the edge of the recording paper is supported by the cut section to prevent it from sliding into the printing section.Furthermore, the cut recording paper is supported by a paper holder to prevent it from falling outside and to prevent accidents caused by it being blown away by the wind. It is designed to prevent this.

A first embodiment of this invention will be explained based on FIGS. 1 to 5. Reference numeral 1 denotes a printer cover having a printing port 2 formed in its upper part, and a printing section 5 consisting of a platen 3 and a dot printer head 4 that moves along the platen 3 is provided inside the printer cover 1. A pinch roller 6 is connected to the platen 3 for feeding out a receipt paper 7 and a journal paper 8, which are recording papers, respectively. At the top of the printing section 5, there are guide plates 9, 10 that vertically define the withdrawal path for the receipt paper 7 and the journal paper 8.
A rubber stamp 1 is provided inside one guide plate 9.
1 is provided. Further, on the top of the rubber stamp 11, a cutter 12, which is a cutting part, is attached to a cutter cover 13.
It is movably supported while being covered from above. A cover 14 is provided above the guide plate 10.

The printer cover 1 is provided with a tunnel-shaped paper holder 15 that guides the receipt paper 7 obliquely upward. The upper and lower inner surfaces of this paper holder 15 have a parallel part 16 with a length A from the outlet side to the middle part and a narrow facing interval B.
They face each other so that the space from the middle part to the inlet side widens in a tapered shape as it goes toward the inlet side. This expanded portion 17 is formed by bending only the lower surface. Further, the parallel portion 16 is inclined at an angle α with respect to the vertical plane Y. Further, the expanded portion 17 is configured to expand in both directions. Actually, A=15~20
mm, B = 1.5 to 2.0 mm, and α = 60°.

In such a configuration, after the printing operation by the dot printer head 4 is completed, the pinch roller 6 rotates by a certain angle, the journal paper 8 is wound up by a roller (not shown), and the receipt paper 7 is sent out toward the paper holder 15. At this time, the path of the receipt paper 7 is determined vertically from the print section 5 to the top of the cutter 12, and is inclined upwardly from the top of the cutter 12 to the exit side of the paper holder 15, so that the receipt paper 7 is Even if one end of the paper 7 is held down by hand, it will loosen in the space above the cutter 12 where the path is bent as shown in FIG. As a result, the feeding action of the receipt paper 7 is not impaired in any way, and paper jams do not occur between the narrow guide plates 9 and 10 or in the printing section 5. Also,
The receipt paper 7 is prevented from moving in the width direction on the exit side of the paper holder 15. As a result, the receipt paper 7 is wrinkled and the guide plates 9, 10 are narrow.
There is no possibility of paper jams in the spaces or in the printing section 5.
Even if the receipt paper 7 is left cut by the cutter 12, the parallel part 16 of the paper holder 15 is tilted at 60 degrees with respect to the vertical plane, so the friction between the inner surface of the paper holder 15 and the receipt will Receipts do not fall directly off. In particular, since the receipt paper 7 has a tendency to curl,
As shown in the figure, it curves within the paper holder 15 and the frictional resistance with the paper holder 15 increases. This prevents the cut receipt from sliding inside or outside. Furthermore, the receipt is wrapped around the paper holder 15.
Because it is surrounded by wind, it cannot be blown away by the wind. Furthermore, the withdrawal path of the receipt paper 7 is bent at the upper part of the cutter 12, so that even if the receipt slips inward, it will be supported by the upper part of the guide plate 9 and the cutter cover 13 and will not slide down to the printing section 5. You won't get stuck.

Next, a second embodiment of this invention will be explained based on FIG. The same parts as in the previous embodiment are designated by the same reference numerals, and the description thereof will be omitted. In this embodiment, a plane Y' passing through the centers of the platen 3 and the pinch roller 6 is set parallel to the path from the printing unit 5 to the cutter 12, and the plane Y' is set at an angle β with respect to the vertical plane Y. The parallel portion 16 is tilted with respect to the vertical plane Y in a direction opposite to the direction of the tilt.

Therefore, when the leading edge of the receipt paper 7 is pressed, the receipt paper 7 loosens between the entrance side of the paper holder 15 and the upper part of the cutter 13, but this effect becomes more noticeable and the guide plate 9 , 10 more effectively prevents paper jams in narrow areas. Also,
Even if the cut receipt slides inward,
As shown by the imaginary line in FIG. 6, the effect that one end of the receipt is supported in front of the path between the guide plates 9 and 10 increases reliability. This is because the upper route and the lower route are inclined in opposite directions with respect to the vertical plane Y, with the vicinity of the cutter 12 as a boundary.

Note that since the paper holder 15 is formed in a truss shape on the entrance side, the receipt paper 7 does not get caught when entering the paper holder 15.

Since this device is constructed as described above, the movement of the recording paper in the width direction is prevented by the paper holder, and even if one end of the recording paper is pressed, the recording paper can be loosened in the space above the cutting section. This makes it possible to prevent paper jams in the narrow printing section.Furthermore, the recording paper sent upward from the printing section is supported by a tunnel-shaped paper holder that slopes diagonally upward.
This has the effect of preventing the cut recording paper from slipping into the interior, as well as preventing troubles such as falling to the outside or being blown away by the wind.
