Description

Description: TECHNICAL FIELD OF THE INVENTION The present invention relates to a recording apparatus using recording paper capable of recording on only one side such as electrostatic recording paper and thermal recording paper.

[Technical Background of the Invention] Generally, in a recording apparatus such as a facsimile machine, it is necessary to replace the recording paper with a new recording paper when the recording paper is exhausted. The replacement of the recording paper is performed as follows.

First, the reception door of the facsimile is opened, the core of the old recording paper is removed, a new recording paper is set, the reception door is closed, and paper reset processing is performed.

The paper reset process is performed to align the leading edge of the recording paper with the recording position, and is performed according to the flowchart shown in FIG. That is, the recording paper is discharged for a certain length in step 3, the recording paper is cut in step 5, and the recording paper is rewound to the recording position in step 7, and at the same time, the cut recording paper is discharged to the stacker.

FIG. 5 shows a state in which the recording paper is set. In FIG. 5, the roll paper-shaped recording paper 101 is the recording paper conveying roller 1.
It is conveyed to the paper guide 105 by 03. In this case, the inside of the roll paper of the recording paper 101 is the upper side of the paper guide 105.

[Problems of the Background Art] However, as a method of setting the recording paper, a method as shown in FIG. 6 can be considered. In this case, the recording paper 101 is on the outer side of the roll paper and on the paper guide 105 portion. It will be on the upper side. That is, in the recording paper setting method shown in FIGS. 5 and 6, the front and back sides of the recording paper are reversed at the paper guide 105. In this way, the front and back of the recording paper are reversed depending on the method of setting the recording paper. If you mistakenly set the front and back sides of the recording paper in reverse, the received image that was automatically received will be blank, and the recipient cannot be determined, so you cannot request a resend, and you cannot reliably transmit information. There was a problem.

Further, in the thermal recording type recording apparatus, if the front and back sides of the recording paper are set by mistake, the head may be damaged when a received image having a high black ratio is received.

SUMMARY OF THE INVENTION Therefore, in order to solve the above problems, an object of the present invention is to provide a recording apparatus capable of easily detecting whether or not the front and back sides of the recording paper are properly set when the recording paper is replaced. To provide.

[Summary of the Invention] In order to achieve the above object, the present invention is a recording apparatus for performing recording using a recording sheet capable of recording only on one side, and when the recording sheet is replaced, the recording sheet is fed for a certain length. In a recording apparatus that performs a paper reset process of cutting the fed recording paper and discharging it to a stacker, the exchanged recording paper is correctly set to the recording paper discharged to the stacker during the paper reset process. In order to detect and judge whether or not the recording paper is set, a recording paper erroneous set confirmation means for performing a printing operation for printing a predetermined character or pattern is provided.

[Embodiment of the Invention] An embodiment of the present invention will be described in detail below with reference to the drawings.

FIG. 1 is a flowchart showing a paper reset process which is a main part of the recording apparatus according to the present invention. Since the other parts of this recording apparatus are the same as those of the conventional recording apparatus, description of the detailed configuration thereof is omitted.

In this embodiment, the paper reset process performed when replacing the recording paper is used to detect and determine whether the replaced recording paper is set correctly. That is, printing is performed in step 1, and thereafter, the recording paper is discharged (step 3), cut (step 5), rewound to the recording position, and the cut recording paper is discharged (step 7) as in the conventional case. The printing pattern in the printing of step 1 may be a black pattern as shown in FIG. 2 or the date as shown in FIG. 3 may be printed, or a character string such as "OK May be displayed. If the front and back sides of the recording paper are set correctly,
A print pattern as shown in FIGS. 3 and 4 is recorded.
However, when the front and back sides of the recording paper are set by mistake, the cut recording paper is blank. The operator determines whether or not the cut recording paper is printed, and if it is not printed, the front and back of the recording paper is reversed and the recording paper is set again. By re-setting the recording paper, the front and back of the recording paper are set correctly.

[Effects of the Invention] As described in detail above, according to the present invention, it is possible to reliably detect whether or not the front and back sides of the recording paper are properly set when the recording paper is replaced.

[Brief description of drawings]

FIG. 1 is a flowchart showing a paper reset process which is a main part of a recording paper according to an embodiment of the present invention, and FIGS. 2 and 3 show print patterns in a printing operation for detecting erroneous setting of the recording paper. FIG. 4 shows an example, FIG. 4 is a flow chart showing a conventional paper reset process, and FIGS. 5 and 6 are diagrams showing a method of setting recording paper. 101 …… Recording paper, 103 …… Recording paper feeding roller, 105 …… Paper guide.

Claims (1)

[Claims] 1.
