Abstract

PURPOSE:To set automatically a function of preventing missing of information due to mis-setting of recording paper and a proper print density. CONSTITUTION:A thermosensing recording head section comprising a head PKG 1 with recording resistors arranged thereto and a heat sink 2 is provided with a print sensor 3 able to discriminate a print content, thermosensing recording paper 4 on which received information is printed out and a recording paper roller 5 keeping the close contact between the thermosensing recording paper 4 and the resistors of the PKG 1 in the case of thermosensing recording. A specific pattern or the like possessed by the printer is printed out to part of a received original in the case of recording and the print sensor 3 detecting the pattern checks print density as soon as the sensor 3 detects the pattern.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to recording control of a facsimile machine and the like, and relates to a function of preventing information loss due to a setting error of recording paper and a function of automatically setting an appropriate print density.

[0002]

2. Description of the Related Art In a conventional apparatus, when the recording paper is roll paper, information loss due to setting mistakes such as the front and back of the recording paper and the sensitivity is dealt with by describing the setting direction and sensitivity in the apparatus. Further, in the case of plain paper that uses ink, the deviation of the ink, which cannot be detected by the sensor in the ink portion, cannot be detected, and the recorded information may be lost.

[0003]

The above-mentioned prior art does not consider heat-sensitive cut paper or slightly thick plain paper type heat-sensitive paper. All information was missing. Also, in the case of plain paper using ink, information loss due to uneven distribution of ink was not considered.

It is an object of the present invention to check information that should have been printed at the same time as printing on the recording paper to prevent information from being lost due to a setting error or the like.

Another object of the present invention is to realize a print density that is independent of the sensitivity and type of recording paper.

[0006]

In order to achieve the above object, in the present invention, a conventional recording structure is provided with a sensor and a sensor and the presence or absence of information by the sensor so that the recording paper can be checked after printing on the recording paper. It is provided with a control function capable of discriminating the concentration.

[0007]

According to the present invention, with the above-described structure, it is possible to prevent the loss of information due to the heat-sensitive recording paper set upside down by identifying whether or not the recording paper is printed and determining whether or not to continue the printing. It is a recording control means.

Another function of the present invention is a recording control means for discriminating whether or not the printing density is appropriate by a sensor and adjusting the recording density.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIG.

As shown in FIG. 1, a print sensor 3 is arranged in a thermal recording head portion composed of a head PKG1 in which a recording resistor is arranged and a heat sink 2 so that the printed contents can be discriminated and the received information is printed. The heat-sensitive recording paper 4 and the recording-paper roller 5 that maintains the adhesion between the heat-sensitive recording paper 4 and the resistor of the head PKG1.

In FIG. 1, when the print contents arrive at the thermal recording head portion for recording, a specific print pattern held by the printing side device is printed at the right end of the received document. Normally, the transmission source record of the other party is printed within about 0 to 10 mm at the head of the received document, and there is almost no information within about 20 mm at the right end of the document, which is entirely white. Use this part of the chart paper,
All black of a specific pattern (example: horizontal; 10 mm, vertical; 5 mm) is printed. This is detected by the print sensor 3, and at the same time as the detection, the print density at that time is checked. If the print pattern that should have been printed can be detected, the print density is checked. If it is an appropriate value, the normal print operation is performed as it is. If it is inappropriate, the print density is controlled according to the preset print density format. If the print pattern cannot be detected here, the recording paper is ejected, and the operator is prompted to determine how many sheets have been ejected to prompt an appropriate setting, and further eject only the inappropriate recording paper generated by the intermediate setting. Increase the probability of normal recording.

[0012]

According to the present invention, it is possible to discriminate whether or not printing has been performed on a recording sheet and to judge whether or not to continue printing.
It is effective in preventing information loss due to thermal recording paper set upside down, and a sensor is used to identify whether the print density is appropriate, and the print density is adjusted to obtain a constant print density. Especially effective.
