きないという問題がありた。The above conventional technology does not take into account the identification of special recording paper, and if the recording paper is made of a material that is not compatible with the ink used, the quality of the recording surface may deteriorate or paper jams may occur. There was a problem. Particularly when recording with a recording paper that has been subjected to special surface treatments such as polyester coating or coating with a coloring agent, there is a problem in that normal recording cannot be performed even if the front and back sides are reversed.

紙動作を行っても異常紙と判定した場合には、。The sensor detects the marker on the recording paper and sends it to the control circuit. The control circuit determines whether or not the paper is normal based on the position of the marker and the shape of the marker based on the output of the rice feeder and the sensor output at the same time, and if the paper is normal, the paper feed is continued. When the printing operation starts and it is determined that the paper is abnormal, the feeding tc operation is stopped, the paper is transported in the opposite direction, and the paper feeding operation is started againd.In this way, when it is determined that the paper is abnormal, multiple The H1 operation is performed several times, and if the paper is determined to be normal during that time, the process proceeds from the paper feeding operation to printing.
記録紙ケ逆方向に搬送し給紙動作を停止する。The recording paper is conveyed in the opposite direction and the paper feeding operation is stopped.
これによって正常紙のみを正しく給紙することかできる
。This allows only normal paper to be fed correctly.
以下、本発明の実施例を絖明する。 Examples of the present invention will be explained below.

−２が設けられている。FIG. 1 is a diagram showing an embodiment of the present invention. A drive motor 2 equipped with a rotation amount detector 1 such as a tally encoder is connected to a paper feed gear 4-1.4 via a drive gear 3'a'.
-2 is connected, and paper feed gears 4-1 and 4-2 are coaxially provided with paper feed gears 5-1 and 5-2 whose surfaces are made of a material with a large friction coefficient such as rubber. be. The recording paper 6 is conveyed between paper feeding rollers 5-1 and 5-2. Markers a-1 and 8-2 are printed on the first side of the recording paper 60. Mark detectors y-1 and 7, such as photocouplers, are placed on the path through which the recording paper 6 is conveyed and the markers 8-1 and 8-2 pass.
-2 is provided.
駆動モータ２の回転により給紙ａ−ラ５−１゜５−２間

紙６の送り量検出器として作動する。Since the recording paper 6 is conveyed between the paper feeding rollers 5-1 and 5-2 by the rotation of the drive motor 2, the rotation amount detector 1 operates as a feed amount detector for the recording paper 6.

The output of is sent to the control circuit 9. When the copy switch 10 is pressed, the control circuit 9 turns on the drive motor 2'1 and starts paper feeding operation. The mark detectors 7-1 and 7-2 detect the presence or absence of the recording paper and the marks 5-1, 8-2 when the recording paper 6 passes therethrough. The control circuit 9 detects the mark 8-1.8 based on the output of the mark detector 7-1.7-2 and the output of the rotation amount detector 1.
The position or size from the paper edge of -2 is determined to determine whether or not the recording paper 6 is normal. If it is determined to be normal, the paper continues to be conveyed and the printing operation begins.

紙を停止する。Because only normal paper is fed, normal paper may be determined to be abnormal paper, but if the recording paper 6 is conveyed in the opposite direction and paper feeding is stopped at this time, it will be necessary to reduce the amount of paper used and copy. The switch 10 must be pressed to start the paper feeding operation. However, if abnormal paper is inserted and the paper is fed upside down, or if the paper is fed upside down, no mark detection output is output from mark detector 7-1 or 7-2. It is impossible to judge that. Therefore, if the normal paper is determined to be abnormal paper, the control circuit 9 automatically starts the paper feeding operation even if the recording paper 6 is conveyed in the opposite direction. If the paper is determined to be abnormal in this way, it is transported in the opposite direction.
The operation of paper feeding is automatically repeated several times, and if it is determined that the paper is abnormal even after a predetermined number of times, the recording paper 6 is conveyed in the opposite direction and paper feeding is stopped.
このときに始めて使用省には制御回路９から異常紙表示
のＬＥＤｌｌを点滅させるなどして知らせる。Only at this time does the control circuit 9 notify the user by blinking the LED 11 indicating the abnormal paper.
所定の回数以前に正常紙と判定できたときには搬送を紙
はプリント動作に入る。If the paper is determined to be normal before a predetermined number of times, the paper is transported and begins a printing operation.

一である。Figure 2 shows a flowchart of the operation. Of course, it is not necessary to display an abnormality. Marker detection can be performed by detecting only the position from the edge of the paper, by detecting the width of the marker, by detecting multiple markers, or by a combination of these, but if an abnormality is determined, multiple markers are detected. The same is true for repeating paper feeding.

Based on the reflection of the recording paper, the presence or absence of the recording paper and the mark 8 on the recording paper are detected. In FIG. 5, number H indicates the white portion of the recording paper, and Lo indicates the output of the sensor 7 when there is no recording paper or when the mark portion on the recording paper is reflected.
コピースイッチ１０が押されたとき正常動作ではセンサ
７の下に記録紙６は無いからセンサ出力はＬｏである。In normal operation when the copy switch 10 is pressed, there is no recording paper 6 under the sensor 7, so the sensor output is Lo.

ことによりて測る。When the recording paper 6 is conveyed and its leading edge is below the sensor 7, the sensor output becomes Hi, and becomes LO during the period when the mark passes. The micro combinator 12 measures the length from the leading edge of the recording paper to the mark by counting the output of the FGi of the motor 2.

Suppose that the mark fli5 has a layer of dust etc. and the number of FG pulses has become l'. When the number of FG pulses from the recording edge to the mark and from the mark part is not m,%, the micro combinator 12 determines that the recording paper 6 is abnormal paper, and sets the forward/reverse rotation signal 17 to Lo in order to reverse the motor 2. do. motor 2
is reversed and conveyed in the opposite direction until the leading edge of the recording paper 6 is reached again. This is the first paper feeding operation. Thereafter, the motor 2 is rotated in the normal direction again, and the number of FG pulses at the leading edge of the recording paper and the mark portion is measured to determine the type of paper. The second time in FIG. 4 is the state when the dust on the mark portion has been removed, m and n have been measured correctly, paper feeding has been completed, and the motor 2 has been turned off.
