Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a recording head that records one image on recording paper based on an image signal, and a roll recording head that records one image on recording paper based on an image signal, and a roll recording system that winds and holds the recording paper that is fed to the recording head into a roll. The present invention relates to a recording device including a paper holding section.

As a method for holding recording paper rolled into a four-roll shape in a recording device, there is a method in which a shaft is passed through the core of the roll paper and the shaft is held by a bearing provided in the recording device main body, and a method in which the shaft is held by a bearing provided inside the recording device main body. Some box-shaped or plate-shaped O-roll paper holders are provided with a stand to hold the outer periphery of the roll paper in contact with the holder. In the former case, the load when unloading the recording paper is light, the unloading is smooth, and the recording paper does not jump when unloading, so there is less need to drive the relative position of the recording paper to the front and rear. However, when installing the recording paper in the main body, it takes time and effort to pass the shaft through the shaft core of the recording paper and then engage the shaft with the bearing of the main body. It also has the disadvantage that the paper and armpits tend to sag due to the above-mentioned load.

On the other hand, in contrast to the former, in order to install the recording paper in the main body, it is sufficient to simply place the recording paper on the roll paper holder.
It has the advantage of being easy to handle, but when unloading ML recording paper, the surface of the paper and the surface of the roll paper tray are in contact with each other, so the load fluctuates and the roll paper holder is unloaded. In addition, when the recording paper is driven intermittently, there is no means to regulate the position of the recording paper, so the recording paper tends to jump and change its relative position with respect to the head PK, which also causes noise. are doing.

Recently, devices have been designed with an emphasis on ease of handling, and the latter method described above, that is, a method in which recording paper is loaded by simply placing the roll recording paper on the roll paper holder. has been widely used. However, this
The above-mentioned drawback of the method, which is the Oa roll paper ejection during paper unrolling, is solved by pressing the top surface of the cylindrical roll paper with a constant pressure.

This kind of recording device is equipped with a cover member that covers the roll of recording paper, and when replacing the roll paper, this cover member is opened. In order to press the cough roll paper with a constant pressure, a roll paper pressing member is provided that is linked to the opening/closing operation of the cover part, and the cough roll paper pressing member is retracted from the roll paper surface in conjunction with the opening of the cover part. P To make it easier to replace the roll paper, and to close the cover member (and press the roll paper presser member against the top surface of the roll paper with a constant force), the roll paper presser member presses the cover member against the upper surface of the roll paper with a constant force. A recording device has been proposed that also functions as a member for maintaining a fixed position.

An object of the present invention is to provide a ML recording apparatus as described above, which is equipped with a device for displaying the actual running distance of the recording paper.

That is, the present invention includes a recording head that records an image on recording paper based on an image signal, and a rolled recording paper holding section that winds and holds the recording paper supplied to the first recording head in a roll. In the recording device, the tray on which the roll of recording paper is placed is supported by a rotary feeder at one end so as to hold the roll of recording paper against the base, and the other end of the tray holds the roll of recording paper. and a pressing member, and the traveling distance t of the recording paper described above.
