Abstract

PURPOSE:To certainly exclude oblique and meandrous movements of recording paper in a course of conveyance by providing a means which, previously to the recording paper being held between a holding roller and a paper supply roller, contacts said paper on its overall width and supports its empty weight up to its receiving position. CONSTITUTION:Recording paper P, pulled up from a deck part 20 by means of feed rollers 30, 130, is led to an oblique movement preventive roller 90 along a paper guide 25 which has width nearly equal ro that of said paper P. Since said roller 90 not only supports empty weight of the paper up to the deck part 20 but also excludes both oblique and meandrous movements which occur during this supporting, the lower paper feed roller 30 and a holding roller 70 can convey the recording paper P in a condition where the abovementioned movements of the paper do not occur in the position of recording.

Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a recording device, and particularly to a fanfold paper stored below a recording position by a recording means.

The present invention relates to a recording apparatus that performs recording by continuously conveying continuous paper such as roll paper to a recording position during recording.

[Prior Art] Generally, this type of recording apparatus is equipped with a conveyance system for supplying recording paper towards a recording means and for removing it from the recording means, and the conveyance system includes a paper feed roller driven by a motor. , a presser roller or the like is provided that faces the paper feed roller and presses the recording paper toward the paper feed roller.

During recording, the recording paper is held between a paper feed roller and a presser roller, and as the paper feed roller rotates, the paper stored below the recording position is continuously pulled upward, and the recording paper is held by the recording means. A recording is made.

Here, the holding roller has a constant shaft diameter over the entire width in the axial direction, and since it presses the recording paper against the paper feed roller, Wh 71 is partially increased, for example, the shaft diameter at approximately the center in the axial direction is set to a constant value. Generally speaking, it is formed so that the recording paper can be held in that area. This is because even if an attempt is made to clamp the recording paper over its entire width, the pressing force will not be uniform due to errors in manufacturing and installation of the presser roller, resulting in skew or meandering of the recording paper during conveyance.

In other words, in the conventional recording device, the recording paper stored below the recording device is pulled up by a paper feed roller and a presser roller, and the presser roller is connected to the paper feed roller through the recording paper. It had a configuration with a small area. However, with conventional devices that support the weight of the recording paper until it reaches the storage position in a small area, if shaking occurs during the conveyance process of the recording paper, for example, the flow of recording paper from the storage section may not be smooth. There is a problem in that it is not possible to remove the skew or meandering of the recording paper that occurs when the recording paper is not properly aligned, resulting in disturbances in the recording state or a so-called paper jam.

[Purpose] The present invention has been made in view of the above-mentioned conventional problems, and is designed to contact the recording paper over its entire width before being held between the presser roller and the paper feed roller, and to prevent the recording paper from being placed in the storage position. It is an object of the present invention to provide a recording apparatus that can reliably eliminate skew and meandering during the conveyance process by providing means for supporting the weight of the recording paper.

The transport operation of the transport system configured to be separable from the recording means as described above will be explained.

Pulled from the deck part 2o by the feed rollers 30, 130"=
The removed recording paper is guided to a skew prevention roller 9o along a paper guide 25 having a width approximately equal to that of the recording paper. This skew prevention roller 8o supports the paper's own weight up to the deck section 2o, and removes the skew and meandering of the paper that occurs during that time. The recording paper P can be conveyed in a state where no rowing or meandering occurs.

Next, the wrinkles on the recording paper P caused by the tensile force during the conveyance process are removed by a wrinkle removing roller 100 before reaching the recording position, and then the platen 110 and the suction fan 11
2, the recording surface is regulated to be flat, and the printer 10 performs recording in this state.

The recorded recording paper is guided by the paper guide 115 toward the upper paper feed roller 130 and the upper presser roller 140, and then separated from the feed roller 130 by the separation plate 142, and then passed through the paper guide 145 and stacker roller 150 to the stacker 6. is deposited in

In the stacker 6, the convex portion 160 is located at the center of the stacked recording sheets P in the depth direction, that is, on the front side F from the center of gravity, and the stacked recording sheets P hang on the back surface B of the stacker 6. Therefore, the stacked recording paper is not biased toward the front due to the impact caused by opening and closing of the transport system storage section 2, and when the stacker door is subsequently opened to take out the recording paper, the recording paper does not collapse from the opening.

In this way, since the container of the transport system including the drive mechanism can be separated from the recording means, the transport state can also be inspected in the open state.
