Description

Description: TECHNICAL FIELD The present invention relates to a recording apparatus, and more particularly to a recording apparatus that uses continuous paper such as roll paper or fanfold paper as a recording medium.

[Prior Art] Generally, in this type of recording apparatus, a conveying system for supplying a recording medium (hereinafter referred to as recording paper) to a recording unit and for separating the recording medium from the recording unit is provided, and the conveying system is equipped with a motor. A driven paper feeding roller, a pressing roller that faces the paper feeding roller and presses the recording paper toward the paper feeding roller, and the like are provided. When mounting the recording paper on such a recording apparatus, first, the operator positions the leading end of the recording paper between the paper feed roller and the pressing roller and holds it between them.
Prepare for recording. Thus, at the time of recording, the recording paper is sandwiched between the paper feed roller and the pressing roller, the recording paper is conveyed as the paper feed roller rotates, and recording is performed by the recording means.

A conventional recording apparatus of this type includes a pressing roller that is pressed against a paper feed roller by a spring. When the recording paper is attached, the spring is bent to separate the pressing roller slightly from the paper feed roller, and the leading edge of the recording paper. Which allows you to insert
Alternatively, there is one in which the connection between the paper feed roller and the drive system is released when the recording paper is attached, and the paper feed roller is manually rotated so that the recording paper can be held.

However, since the working area within the apparatus that is allowed by the operator when mounting the recording paper is limited, the gap obtained between the pressing roller and the paper feeding roller when mounting the recording paper is small. In the conventional example of No. 2 or the second conventional example in which no gap is provided, there is a problem that it is difficult to mount the recording paper.

[Purpose] Further, in order to feed the recording paper in a good state toward the sandwiching position of the paper feeding roller and the pressing roller, it is conceivable to appropriately arrange an appropriate guide member such as a roller. It is desirable that the mounting of the recording paper does not become difficult even by disposing such guide rollers.

The present invention has been made in view of these points,
When the recording paper is attached, the presser roller and the appropriate guide roller can be largely separated from the paper feed roller by a simple operation to secure a sufficient working area, which facilitates the attachment of the recording paper and also allows the space between the rollers during recording. It is an object of the present invention to provide a recording apparatus which is appropriately positioned so that the recording paper can be reliably fed or conveyed.
