Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a recording apparatus using recording paper with perforations.

[0002]

2. Description of the Related Art Conventionally, this type of recording paper has been used in a recording device such as a dot printer connected to a computer. At this time, the recording paper is folded at the perforations and placed outside the recording device. Then, the leading edge of the recording paper is pulled out and inserted into the recording apparatus from the outside, and is put on standby for the recording operation.

[0003]

However, in the above-mentioned configuration of the conventional technique, since the recording paper is placed outside the recording device, the place where the recording paper is placed is different from the place where the recording device is placed. There was a problem that the space had to be secured and an extra space had to be secured. Also,
Since the recording paper is not frequently exchanged, it is usually placed under the mounting table of the recording device.Therefore, when replacing the recording paper, the heavy mounting table on which the recording device is mounted is removed and replaced. It is necessary to place the recording paper for the recording, return the mounting table to the original position again, and further pull only the leading edge of the recording paper to set it in the device, which causes a troublesome replacement work of the recording paper. Was.

To solve this problem, the above-mentioned recording paper may be set inside the recording apparatus, but in this case, the following problems occur.

That is, when the perforated recording paper is folded and stored inside the apparatus, the recording paper is folded in the horizontal direction and overlaps with the bottom surface of the apparatus. When the overlapping recording papers are conveyed, if the conveying direction is changed to the direction perpendicular to the bottom surface of the apparatus, in order to smoothly convey the recording papers without causing a paper jam, as shown in FIG. It is necessary to gradually change the conveying direction with a distance from the uppermost surface of the recording paper on which the recording paper is placed to the recording means.

However, this causes a problem that the apparatus becomes large as much as the distance from the uppermost surface of the recording paper on which the recording paper is placed to the recording means. To solve this problem, the distance from the uppermost surface of the recording paper to the recording means may be reduced, and the recording means may be arranged immediately above the uppermost surface of the recording paper. In this case, The problem occurs.

That is, when changing the conveying direction of the recording paper from the horizontal direction to the vertical direction, in order to smoothly convey the recording paper without causing a paper jam, a roller for changing the conveying direction as shown in FIG. 5B. However, the height of the device cannot be reduced by that much, which is a problem.

The present invention solves the above-described problems, and accommodates perforated recording paper inside, reduces the installation space of the apparatus as a whole, and ejects the recording paper smoothly without jamming. A recording device capable of performing the above is provided.

[0009]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention provides a storage portion inside the apparatus for storing a recording sheet which is perforated and is folded at the perforations.
At the uppermost position on the recording means side of the storage section, there is provided means for pressing the lifting of the leading edge of the recording sheet on the recording means side which is lower than the currently transported recording sheet when the recording sheet is being conveyed.

[0010]

According to the present invention, with the above-described structure, a storage section for storing the recording paper, which has perforations and is folded at the perforations, is provided inside the apparatus, and the recording paper is on the flush uppermost surface of the storage section. It is guided and conveyed horizontally from the discharge port of the storage section. In this way, since the recording paper stacking direction and the recording paper transporting direction are the same, it is not necessary to provide a member for changing the transporting direction, and the restriction when reducing the size of the device is eliminated accordingly. You can

Further, when the recording paper is conveyed, at the uppermost position on the recording means side of the storage section, the leading end of the recording paper on the recording means side at a position lower than the recording paper currently being conveyed at the time of conveying the recording paper is held. Since only the recording sheet currently being conveyed is conveyed to the recording means by providing the means for pressing the rising, the recording sheet is smoothly discharged without jamming.

In FIG. 1 and FIG. 2, reference numeral 1 denotes a device housing. Reference numeral 2 is a recording paper with perforations, which is folded and stored at the perforations. Reference numeral 3 denotes a storage unit in which the recording paper 2 is stored. Reference numeral 4 denotes a substrate cover which forms the uppermost surface of the storage portion 3 and is attached to the back side of the upper surface of the apparatus housing. Further, the lower surface of the substrate cover 4 forming the uppermost surface of the storage portion 3 is formed flush with each other. A control board 5 is covered by the board cover 4, and controls the inside of the apparatus. Reference numeral 6 is a print head for printing image information on the recording paper 2, and 7 is a platen roller provided in contact with the print head 6 to press the recording paper 2 against the print head 6 for conveyance. Reference numeral 8 is a discharge port for the recording paper 2. 9 is a storage unit 3
Is a projection provided on the uppermost side of the print head 6 side, and when the recording paper 2 is being conveyed, the leading end of the recording paper on the recording means side below the recording paper currently being conveyed is held down.
An upper surface 10 is rotatably held with respect to the apparatus housing 1. The upper surface 10 is opened and the recording paper 2 is set in the storage unit 3.

The operation of the recording apparatus configured as above will be described below with reference to FIG. FIG. 3 is a state transition diagram showing a state where the recording paper is conveyed in the recording apparatus of FIG.

First, the user opens the upper surface portion 10 of the apparatus housing 1 as shown in FIG. 3, and sets the recording paper 2 in the storage portion 3. With the upper surface portion 10 opened, the user closes the upper surface portion 10 by pinching the leading edge of the recording paper 2 stored in the storage portion 3 and sandwiching it between the drawer print head 6 and the platen roller 7. Next, a printing instruction is given by an operation unit (not shown). The recording paper 2 is gradually advanced by the rotation of the platen roller 7 and discharged from the discharge port 8 as shown in FIG. In this case, since the recording papers 2 are stacked in the storage portion 3 and the recording papers 2 are conveyed in the same direction, it is not necessary to provide another structure for changing the conveying direction. For this reason, it is possible to eliminate the restriction in reducing the size of the device, and thus it is possible to further reduce the size of the device.

Further, when the recording paper 2 is conveyed, the recording paper 2 is formed by folding and storing a continuous paper. Therefore, as the uppermost recording paper is pulled by the platen roller 7, the recording paper 2 shown in FIG. As shown in FIG. 5, the leading end of the recording paper lower than the uppermost recording paper is also lifted.

However, in the present invention, the projection 9 is provided at the uppermost position of the storage section 3 on the print head 6 side, and the projection 9 is located at the tip of the recording paper 2 stored in the storage section 3 on the print head 6 side. Holds the lift. As a result, the progress of the recording papers lower than the currently conveyed recording paper is regulated, and FIG.
As shown in (c), the crease side of the perforation of the recording sheet currently being conveyed is reversed and advances toward the print head. The folding side of the perforation of the recording paper 2 is guided by the flush lower surface of the substrate cover 4 and is conveyed to the print head 6. When the first perforation of the recording paper 2 is printed, the recording paper 2 is not in a folded state but in a state of being directly connected to the succeeding recording paper 2 after the fold. The recording paper 2 is also conveyed subsequently.

The above operation is repeated until the printing of the image information is completed. If the recording paper 2 does not have the projection 9 as in the present invention, the recording paper 2 causes a paper jam during the conveyance.

The situation will be described below with reference to FIG.
FIG. 4 is a state transition diagram showing a conveyance state of the recording paper when there is no protrusion 9.

First, similarly to the above case, the recording paper 2 is set and a printing instruction is given. The recording paper 2 is shown in FIG.
As shown in (4), the sheet is sandwiched between the print head 6 and the platen roller 7 and starts to be conveyed. Since the uppermost surface of the recording paper 2 is pulled, the lower recording paper is also pulled up, and the leading end on the print head 6 side floats up. Since there is no protrusion 9 here, FIG.
As shown in (b), the lower chart paper is lifted as it is,
Further, the fold side of the recording sheet 2 currently being conveyed also advances without being reversed.

As shown in FIG. 4C, the recording paper 2 lower than the currently conveyed recording paper 2 is also drawn between the print head 6 and the platen roller 7, and the lower recording paper 2 is also drawn. Subsequently, it is drawn between the print head 6 and the platen roller 7. As described above, it can be seen that a paper jam occurs when the recording paper 2 is simply stored inside the apparatus.

As described above, according to the present invention, since the storage portion 3 for storing the recording paper 2 is provided inside the apparatus, the upper surface portion 10
The recording paper 2 can be exchanged by simply opening and closing, and the recording paper 2 can be easily exchanged. In addition, the protrusion 9 is provided at the uppermost position of the storage section 3 on the print head 6 side. Since it is possible to prevent the leading end of the recording paper which is lower than the conveyed recording paper 2 on the side of the print head 6 from being lifted up, even if the perforated recording paper is stored inside the device, paper jam does not occur. It can be transported smoothly.

Further, since the recording paper 2 is stored inside the apparatus, it is not necessary to secure the recording paper 2 separately from the place where the recording paper 2 is placed in the apparatus main body, unlike the case where the recording paper 2 is placed outside the apparatus. Therefore, the installation space of the entire device can be reduced.

Further, since the back side of the upper surface portion 10 of the apparatus housing 1 forms the uppermost surface of the storage portion 3 and guides the conveyance of the recording paper, the number of parts is reduced by that amount and the entire apparatus is downsized. be able to.
