Description

[Detailed description of the invention] [Purpose of the invention] (Field of industrial application) The invention relates to a recording device, and more specifically, the present invention relates to a recording device that stores cut recording paper onto a tray by gravity. The present invention relates to a recording device.

(Prior art) In order to make the device more compact, the recording device has a method in which the cut recording paper is stored on a tray by natural fall without using a forced conveyance means such as an ejection roller. There is something like this.

FIG. 2 shows a facsimile machine as such a recording device. A recording paper roll 2 is held approximately in the center of the device housing 1, and the recording paper roll 2
A thermal recording head 3 and a platen roller 4 are disposed on the left side, and a cutter 6 is further disposed on the left side with a guide plate 5 interposed therebetween. Further, a recording paper outlet 1a is formed on the left side plate of the device housing 1, and one end of the tray 7 is inserted into the recording paper outlet 1a, and the tip of the one end extends to the cutter 6. has been done. Note that 8 indicates a document table, and a reading means is disposed on the right side inside the device housing 1.

In this facsimile apparatus, the recording paper 2a is pulled out from the recording paper roll 1 by rotating the platen roller 4, and while the recording paper 2a is conveyed in the direction of the cutter 6, the recording paper 2a is pulled out by the thermal recording head 3. Record on top. The recording paper 2a on which recording has been completed in this manner is conveyed until the recording portion thereof passes the cutting portion 6a of the cutter 6, and is cut by the cutter 6. Cut recording paper piece 2
b is accommodated on the tray by the free fall of the cut end.

(Problem to be solved by the invention) By the way, in the above-mentioned facsimile device, when the remaining amount of the recording paper roll 2 becomes low and the recording paper starts to be fed out from near the core, the recording paper has a strong curling tendency. is attached, so that the recording paper piece 2c cut by the cutter 6 after recording is completed.
As shown in the figure, the rear end 2c' of the recording paper piece 2c curls and blocks the recording paper outlet 1a. In this state, when the next recording paper 2a is ejected, the leading edge of the recording paper 2a will touch the recording paper piece 2.
c abuts against the rear end 2c' of the recording paper 2c', thereby causing the recording paper 2
There is a risk that the advance of the paper a will be hindered and a paper jam will occur.

Therefore, an object of the present invention is to provide a recording device that prevents the occurrence of paper jams.

[Structure of the invention] (Means for solving the problem) The recording device of the invention has an idling roller close to a recording paper outlet, and a lower circumferential surface of the idling roller is lower than an upper edge of the recording paper outlet. It is also placed so that it is positioned downward.

(Function) According to the recording device of the present invention, the curly recording paper is guided by the idle roller and passes through the recording paper outlet without coming into contact with the upper edge of the recording paper outlet. .

(Example) Hereinafter, an example of the present invention will be described in detail based on the drawings.

FIG. 1 shows the main parts of the recording apparatus of this embodiment. This recording device includes a thermal recording head 11
and a recording means 13 consisting of a platen roller 12
A cutter 16 consisting of a fixed blade 14 and a rotating blade 15, and a tray 17 are arranged close to each other, and a lower guide plate 18 and an upper guide plate 19 are arranged between the recording means 13 and the cutter 16. A guide means 20 consisting of the following is provided.
Further, a recording paper outlet 22 is formed in the side plate 21 of the apparatus housing 100, and one end portion of the tray 17 is inserted into this recording paper outlet 22. Above the one end of the tray 17 and to the left of the rotary blade 15, a guide member 23 for guiding the recording paper to the recording paper outlet 22 is provided. A roller 24 is provided. This roller 24 is connected to the shaft 2
5 and a roller body 26 made of sponge rubber.
It is supported for free rotation. Also, the roller 2
4 is the lower circumferential surface 2, as is clear from the figure.
6a is located below the upper edge 22a of the recording paper outlet.

When the recording operation starts now, in this recording apparatus, the platen roller 12 is rotated in the direction of the arrow to pull out the recording paper 30 from the recording paper roll (not shown), and the recording paper 30 is conveyed in the direction of the cutter 16 while being heated. Recording paper 3 by head 11
Record on 0. The recording paper 30 on which recording has been completed in this manner is conveyed until its recording portion passes through the cutting section of the cutter 16, and is cut by the cutter 16. At this time, the leading edge 30 of the recording paper 30
a advances along the tray 17 and passes through the recording paper outlet 22. Cut recording paper piece 3
0' (double-dashed line) shows tray 1 due to natural fall.
7.

Here, if the recording paper 30 is curled due to a strong tendency to curl, even if the recording paper 30 rises from the tray 17 while being carried out through the recording paper outlet 22, the recording Paper 30 is roller 2
4, the recording paper 30 is smoothly conveyed out of the apparatus without coming into sliding contact with the opening edge of the recording paper outlet 22. Also, as shown by the solid line in the figure, the recording paper pieces 3 on the tray 17
0″ is curled, the rear end 30a″ is
It comes into contact with the roller 24 mentioned above. At this time, as is clear from the figure, the recording paper piece 30'' and the guide member 23
A gap is ensured between them. In this state, the leading edge 30a of the recording paper 30 to be conveyed next passes through the gap, and then passes between the recording paper piece 30'' and the roller 24.
However, at this time, since the roller 24 is freely rotatable, the recording paper 30 is guided by the roller 24 and smoothly passes through the recording paper outlet 22.

In this embodiment, the roller body 26 is made of sponge rubber, but rollers made of various materials may be used as long as they can effectively guide the recording paper.

[Effects of the invention] As detailed above, according to the recording apparatus according to the invention, the idler roller is close to the recording paper outlet and the lower circumferential surface is located below the upper edge of the recording paper outlet. Because of this arrangement, even if the recording paper is curled, it can be carried out smoothly without coming into contact with the end of the recording paper outlet, making it possible to prevent the occurrence of paper jams.
