The present invention relates to a recording paper feeding method of a facsimile system, and more particularly, to a recording paper automatic feeding method of a facsimile system having an anti-Curi structure in which the recording paper is mounted on the rear side and the printed recording paper is discharged in the rearward direction.

In general, a facsimile with an anti-ical structure is mounted with a recording sheet at the back of the system as shown in FIG. 1 and the printed recording sheet is discharged to the rear. Such an anti-curl structure has a thermal print head (TPH) 1, a platen roller 2, and a cover C-RX between the recording paper insertion port and the discharge port as shown in FIG. 1. (3), paper sensor (4,5), Auto-cutter (6), Guide-cutter (7), Stacker Guide (8) , Stacker-TX (9), Receive Stacker (Guid-RX) (10), Cover-paper (11), Recording paper (12), Recording paper insertion slot (13), Recording paper presence / absence detector (Paper empty sensor) 14, recording paper jam sensor (paper jam sensor) 15, recording paper storage box 16, the exterior 17 and the like.

As described above, in the system of the anti-curl structure, an open lever (not shown) is used to generate (maintain) a gap between the platen roller 2 and the TPH 1 to insert the recording paper. To generate a gap, and then insert the recording paper through the recording paper insertion hole 13 and push the recording paper so that the tip of the recording paper is visible on the stacker guide 8. As described above, when the recorder is pushed to the outside and the receiving cover 3 is closed, the automatic cutter 6 operates to cut the recording sheet. At this time, the system controller enters the standby state.

However, the above-described anti-caloric system manually inserts recording paper, which causes a problem of wrinkled recording paper when the recording paper is inserted. In addition, the above system has a problem that it is not easy to insert the recording paper manually because the recording paper insertion opening 13 is narrow and the recording paper insertion passage 18 is long. When the receiving cover 3 is closed, the automatic cutter 6 operates to record the recording paper. When the paper is inserted at an angle, the recording paper may be jammed.

It is therefore an object of the present invention to provide a method for controlling the insertion of a facsimile system recording sheet having an anti-ical structure automatically.

Still another object of the present invention is to provide a method for controlling the insertion of recording paper to a printing position by driving an internal step motor by an output of a recording paper insertion sensor in an anti-facial system having an anti-ical structure.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a block diagram of a facsimile system for carrying out the present invention, which has a central processing unit 20 for controlling the system and a plurality of keys. OPE (Operating Eqipment) 22 for displaying the generated and input display data, the transmission motor 26 and the reception motor 28 driven by the input of the drive control signal, and the input of the motor drive control signal. By connecting the motor driving unit 24 for driving the transmission motor 26 and the receiving motor 28, the central processing unit 20 and the OPE 22 and the motor driving unit 24 connected to the various sensors The detection signal inputted from the central processing unit 20 is inputted, and the display signal and the motor driving control signal from the central processing unit 20 are transmitted to the transmission motor 26, the reception motor 28, and the OPE 22. Consists of IOD (Input / Output Division) (30) It is.

In the configuration of FIG. 1, reference numerals 32, 34, 36, and 38 denote the recording paper detectors 4, 5, the recording paper presence / absence detector 14, and the recording paper jam sensor 15 having the anti-ical structure as shown in FIG. Line to input output from.

3 is a control flowchart according to the present invention, the first process of detecting the presence of the recording paper in the standby mode during the initial operation, and the recording paper by driving the receiving motor (platen roller) when it is determined that the recording paper in the first process Is loaded into the printing position, the second step of searching whether the recording sheet is in the printing position, and when the search of the second process determines that there is no recording sheet in the printing position, the receiving motor is driven and the recording sheet is in the printing position. A third process of stopping the receiving motor and displaying a recording paper cut statement and a message at the same time and searching for an input of the cutting key; and cutting the recording paper into the standby state when determining that the cutting key is input as a result of the search of the third process. When the cutting key is not input within a predetermined time, the fourth process directly enters the standby mode.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

If a system like FIG. At this time, the standby state is the same as the normal mode of the standby state of the facsimile.

The central processing unit 20 which has performed the above standby state mode searches whether the recording sheet is inserted as a signal input to the line 36 in step 42 of FIG. The line 36 is a line to which the output of the recording sheet presence / absence detector 14 of FIG. 1 is input. The recording paper presence detector 14 detects the presence or absence of the recording paper inserted in the recording paper insertion passage 18 and outputs the result to the line 36 of FIG. Therefore, the central processing unit 20 detects the presence or absence of the recording paper in the system by the output of the recording paper presence detector 14, and if there is no recording paper, the recording paper emote display message to the OPE 22 through the IOD 30 in step 44. Outputs

If it is determined in step 42 that there is a recording sheet, that is, the user manually inserts the recording sheet into the recording sheet insertion passage 18, the recording sheet is positioned to the initial point of the platen roller 2 through the recording sheet presence / absence detector 14. The CPU 20 determines that there is a recording sheet by inputting the output of the recording sheet presence detector 14 in step 42, and receives the driving motor control signal to the motor driving unit 24 through the IOD 30 in step 46. The platen roller 2 is driven by outputting the signal, and the signal input of the line 32 is searched through the IOD 30 in step 48 to search whether the recording sheet is in the print position.

The motor driver 24 which receives the reception motor driving control signal through the IOD 30 drives the reception motor 28. When the receiving motor 28 is driven, the platen roller 2 connected to the shaft of the receiving motor 28 is rotated. When the platen roller 2 is rotated, when the recording paper sandwiched by the recording paper insertion passage 18 is transferred to the discharge side, the recording paper is discharged through the point where the TPH 1 is placed by the above-described transfer. When the recording sheet reaches the position of the recording sheet detector 4 by the discharge conveyance of the recording sheet as described above, the recording sheet detector 4 outputs the recording sheet detection signal to the line 32 of FIG. At this time, the central processing unit 20 inputs the output of the line 32 in step 48 to determine that the recording paper has reached the print position, and in step 50 the motor driving unit 24 receives the reception motor driving stop signal through the IOD 30. ). The motor driver 24 which receives the reception motor driving stop signal interrupts the driving control signal output to the reception motor 28 to stop the driving of the reception motor 28. The CPU 20 then inquires whether to cut the recording sheet by outputting the OPE 22 through the IOD 30 through the recording sheet cutting inquiry message in FIG. 52. In step 54, the central processing unit 20 analyzes a key signal input from the OPE 22 through the IOD 30 to search whether a cutting key is input.

When the recording sheet cutting key is input from the OPE 22 during the searching, the central processing unit 20 drives the automatic cutter 6 of FIG. 1 through the IOD 30 in step 56 to cut the recording sheet. Perform the standby mode of step 58.

If the recording paper cutting key is not input from the OPE 22, the CPU 20 directly enters the standby state of step 58 without performing step 56 and performs the standby mode.

Therefore, when the recording paper is initially inserted, the recording paper can be automatically fed and cut to the printing position to facilitate the insertion of the recording paper, and the recording paper jam can be prevented.

As described above, the present invention automatically inserts the recording paper to the printing position by using the paper sensor and the stamping motor in the facsimile system in the anti-cortical structure having the central processing unit, and selectively inserts the recording paper by cutting the recording paper. It can be easily, there is an advantage that can prevent the paper jam (Paper jam) in advance.
