Abstract

PURPOSE:To reduce the elimination work of jammed recording paper by cutting recording paper even if the paper dose not reach paper feeding length and compulsorily feeding the rear end of the recording paper to the vicinity of the paper ejecting port of a roll paper feeding part when paper jamming is generated in the main body except the roll paper feeding part. CONSTITUTION:When the generation of paper jamming is detected by a plotter 2 after a roll paper feeding part 10 is selected, recording paper is carried and recording is started, the effect is notified to a system control part 5. The plotter 2 stops all the rollers on the roll recording paper carriage when paper jamming is generated at the part except the roll paper feeding part 10. Subsequently, if the roll recording paper is not cut, the cut of the recording paper by a cutter is executed and the carriage is executed. Subsequently, when the rear end of recording paper and paper ejection are detected by a sensor, the carriage is stopped. By this operation, the cut recording paper is got out of the roll paper feeding part 10 and is compulsorily fed to the vicinity of a paper ejecting port.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a facsimile machine, and more particularly to a facsimile machine which can easily remove recording paper when a paper jam occurs.

[0002]

2. Description of the Related Art Conventionally, in a facsimile machine provided with a roll paper feed unit, if a paper jam occurs while feeding a long recording paper from a roll paper cassette to a main body developing unit, it is controlled to stop all paper feed rollers. However, I try not to make the paper jam worse. In that case, the roll paper feed unit cannot be removed or pulled out, and it is necessary to remove the jammed recording paper for each part. Further, if a paper jam occurs in the roll paper feed unit, cutting the recording paper jammed or overlapped by the recording paper cutter in the roll paper feed unit may damage the cutter. Further, when the cutter blade is rotated in the reverse direction to return to the initial position when the recording paper is jammed, the cutter motor driver may be damaged by a long-time reverse rotation attempt. Further, when a cutting failure occurs due to the abrasion of the cutter blade in the roll paper feeding unit, the trailing edge of the recording paper cannot be detected and all the rollers are stopped, which is the same as the paper jam condition. A facsimile machine equipped with a roll paper feed section and a sheet paper cassette so that it can be mounted freely is described in, for example, Japanese Patent Application Laid-Open No. 61-13864.

[0003]

In the above-mentioned prior art, it is difficult to remove the recording paper when a paper jam occurs in the facsimile apparatus having the roll paper feeding section. SUMMARY OF THE INVENTION An object of the present invention is to provide a facsimile apparatus which solves such a problem and which can easily remove a roll paper feeding unit and is suitable for a recording paper removing operation.

[0004]

In order to achieve the above object, a facsimile apparatus of the present invention comprises means for mounting roll recording paper, a roller for conveying the mounted roll recording paper to a sheet discharge port, a conveyance path, and a roll. If a paper jam occurs in the main body outside the roll paper feed unit, the roll paper is being fed to the specified length if the roll paper feed unit is equipped with an automatic cutter that cuts the recording paper to the specified length. It is characterized in that the roll recording paper is cut and the trailing edge of the recording paper is conveyed to the vicinity of the discharge port even if the roll recording paper is not reached. Further, it is characterized in that a manual cutter is arranged in the vicinity of the discharge port of the roll paper feed unit and, when a paper jam occurs in the roll paper feed unit, the operator is instructed to cut the recording paper by the manual cutter. Further, when the cutting failure of the automatic cutter of the roll paper feeding unit occurs, the cutting operation is further performed a plurality of times, and thereafter, the paper feeding from the roll paper feeding unit is stopped. In this case, it is also characteristic that an automatic cutter replacement instruction message is displayed.

[0005]

In the present invention, when a paper jam occurs in the main body outside the roll paper feeding unit, the recording paper is cut by the control of the system control unit even if the paper feeding length is not reached, and the recording paper is ejected by the discharge roller. The end is controlled so that it is forcibly fed to the vicinity of the paper exit of the roll paper feeder. As a result, the roll paper feeding unit can be easily removed, and the work of removing the jammed recording paper can be reduced. Also, if a paper jam occurs in the roll paper feeder, a message will be displayed on the operation display
Instruct the operator to use the manual cutter provided near the paper exit. This prevents the cutter in the roll paper feed unit from being damaged, and facilitates removal of the roll paper feed unit by cutting the recording paper with the manual cutter, thereby reducing the work of removing the jammed recording paper. Furthermore, if a cutting failure occurs due to wear of the cutter in the roll paper feeding unit,
Under the control of the system control unit, after the recording paper is cut by operating the cutter a plurality of times, the paper is not supplied from the roll paper feeding, and a cutter replacement instruction is given by a message on the operation display unit. As a result, recording paper jam due to defective cutting of the cutter is prevented, and the work of removing the recording paper is reduced even when a paper jam occurs.
