Abstract

PURPOSE:To easily discriminate whether or not the user sets correctly recording paper by feeding the thermosensing recording paper immediately up to a prescribed position when the recording paper is set and printing out a predetermined pattern. CONSTITUTION:After the user loads thermosensing recording roll paper 101 to the facsimile equipment, when the user closes the door and the presence of the recording paper is recognized by the equipment, the size of the recording is detected when a recording paper check print flag is cleared, and a relevant pattern is printed out. Then the recording paper check print flag is set and the processing is terminated.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a facsimile machine that uses a roll of thermal recording paper.

(Prior Art) In this type of apparatus, a roll of thermal recording paper is loaded in a predetermined position, and the recording paper pulled out from the roll is set between a platen roller and a thermal head. At this time, if the recording paper is set diagonally, the image may be distorted during printing or the recording paper may jam.

As a countermeasure to this problem, drawing guidelines on recording paper and visually checking the set state, or providing mechanical guides, but these methods cannot be said to be reliable. Furthermore, as described in, for example, Japanese Patent Application Laid-Open No. 1-142679,
There is also a method of detecting the movement of the recording paper using marks, but this method is expensive and disadvantageous for small devices.

(Problems to be Solved by the Invention) The present invention has been made in view of the problems of the prior art described above, and its main purpose is to easily enable the user to check whether or not thermal recording paper is set correctly when it is set. To provide a facsimile device which can make a judgment based on information and which can be implemented at low cost. Another object is to provide a facsimile machine in which the present invention can be applied regardless of the size of thermal recording paper to be set.

(Means for Solving Problem a) In order to achieve the above object, the present invention first provides (1) a means for detecting that thermal recording paper is set, and a means for immediately feeding the set thermal recording paper. and a means for printing a pattern that allows it to be determined whether or not the thermal recording paper is correctly set.

(2) Furthermore, the above configuration is further provided with means for detecting the size of the set thermal recording paper and means for changing the printing pattern according to the size of the thermal recording paper.

(Function) According to the configuration (1), as soon as the thermal recording paper is set, it is fed to a predetermined position and a predetermined pattern is printed on it. It can be easily determined whether it is set or not.

Furthermore, according to configuration (2), the printed pattern changes depending on the recording paper size set by the user's selection, so the set state can be determined regardless of the recording paper size.

(Example) Hereinafter, embodiments will be described in detail with reference to the drawings.

FIG. 1 shows a plotter section of an embodiment of the present invention, in which 101 is a roll of thermal recording paper;
2 is a thermal head that prints on the recording paper that has been pulled out from the roll and fed; 103 is a thermal head that conveys the recording paper;
In addition, there is a platen roller that supports the back side of the recording paper against the pressure of the thermal head during printing, and 104 is a recording paper guide.Here, for example, if the recording paper is A4 size, a guide is required, but if it is B4 size, it is unnecessary. shall be. Then, as shown in FIG. 4, when recording paper is A4 size, the microswitch 105 is turned on by the recording paper guide 104.
Recording paper size is detected. Reference numeral 106 denotes a pattern printed on the set thermal recording paper, which allows it to be determined whether or not the recording paper is correctly set.

FIG. 2 shows a facsimile machine system in this embodiment. The system includes a scanner 201 that reads image information, a plotter 202 that prints a pattern indicating the setting status of recording paper and facsimile image information, an encoding/decoding unit 203 that compresses and expands the image information, and a device for performing predetermined facsimile communication. A communication control unit 204 of the present invention, a network control unit 206 that connects and controls a modem 2051 line for modulating and demodulating communication data, an operation display unit 207 for communicating with users, and an operation control unit of the present invention. The system includes a system control section 208 that performs facsimile operations and controls predetermined facsimile operations.

Next, the operation of this embodiment will be explained with reference to the flowchart shown in FIG. First, after the user loads the rolled thermal recording paper 101 into the device, the door is closed (step 301), and when the presence of recording paper is recognized (step 302), the recording paper check printed flag is turned off. If so (step 303), the recording paper size is detected (step 304) and a pattern corresponding to it is printed (step 305 if A4, step 306 if B4). Thereafter, the recording paper check printed flag is turned on (step 307) and the process ends.

The printing pattern is, for example, something like the following, which prompts the user to reset if it is not OK.

(Effects of the Invention) As explained above, according to the present invention, (1) pattern printing is always performed immediately after the user sets the thermal recording paper, making it easy to check whether the recording paper is set correctly; This makes it possible to prevent print distortion and jams from occurring. The configuration is simple and can be implemented at low cost. Furthermore, (2) since the printing pattern changes according to the recording paper size set according to the user's selection, the setting state of the recording paper becomes clear regardless of the recording paper size.
