本発明はロール状記録紙を使用する例えばファクシミ
リ受信装置において、巻きぐせのない記録紙の得られる
記録紙のカール取り装置を提供するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention provides a recording paper curl removing device that can be used in, for example, a facsimile receiving device that uses rolled recording paper, and can produce recording paper without curling.
従来のファクシミリ受信機等の記録装置においては、
記録紙にロール紙を使用するものが多い。In conventional recording devices such as facsimile receivers,
Many use roll paper for recording paper.

づいて詳細に説明する。- When the roll paper diameter is large in this type of device, the curling of the recording paper after cutting (paper warpage due to curling) is small and does not pose much of a problem because the roll diameter is large. However, as rolls are used and the diameter approaches the core diameter of the roll, the curls become larger and the recording paper curls significantly on the toilet. Therefore, there was a drawback that the sheet-like recording papers were not stacked in the correct order. In order to eliminate these drawbacks, the present invention has a grip roller and a slip roller disposed before and after the paper handling member so as to apply tension to the recording paper handling member and the recording paper, and will be described in detail below based on the drawings. do.

である。FIG. 1 is a diagram showing essential parts of an embodiment of the present invention,
1 is a roll of electrostatic recording paper, 2 and 6 are rollers for conveying the recording paper, 3 is an electrostatic recording head that applies a latent image to the electrostatic recording paper 1, 4 is a head holding roller, and 5 is an electrostatic recording A cutter for cutting the paper 1 to an appropriate length; 7 a developing device for converting the latent image into a head image; 8 a fixing roller for fixing the head image on the electrostatic recording paper 1; 9 and 10 are grip rollers for discharging and transporting the fixed electrostatic recording paper, 11 is a recording paper handling member for removing curls in the electrostatic recording paper 4, and 12 and 13 are recording paper handling members 11. In order to work together with others to give tension to the recording paper,
Slip rollers made of metal or the like rotate faster than the grip rollers 9 and 10; 14, 15, and 16 are recording paper conveyance guides; and 17 is electrostatic recording paper for one sheet of recorded paper (hereinafter referred to as receiving paper). It is a tray that can be stacked one after another.

る協働作用を説明する。After passing through the cutter 5, the recording paper further passes through a recording paper conveyance roller 6, is developed by a developing device 7, and is further fixed by a fixing roller. On the other hand, when the electrostatic recording head 3 finishes receiving one message, it stops applying electric charge to the recording paper, but the recording paper is further advanced by a distance 1 from the center position of the head to the position of the blade of the cutter 5. At this point, the cutter 5 operates and the electrostatic recording paper is cut to the same length as the transmission original, resulting in one receiving image paper. The received drawing paper passes between the guides 15 and enters the grip rollers 9,10. Furthermore, when the operation of the cutter 5 is completed, the leading edge of the electrostatic recording paper (unrecorded) on the roller 2 side will have a margin of distance 1 from the center of the head to the position of the blade of the cutter 5. In order to eliminate blank spaces, the recording paper conveying roller 2 and the head pressing roller 4 are reversed by a distance of 1, and the leading edge of the recording paper is returned to the head center position in preparation for the next recording. During this time, the received drawing paper for one sheet is transferred to the grip roller 9.
, 10, and a recording paper handling member 11 and a slip roller 1.
2 and 13, and is loaded onto the tray 17. Next, the cooperative action of the recording paper handling member 11, grip rollers 9, 10, and slip rollers 13, 12 will be explained with reference to FIG.

８（一点鎖線）の様になる。Note that FIG. 2 is a partially enlarged view of FIG. 1, and the same members are given the same numbers. If there is no curl removal mechanism, the received drawing paper will still have the curls of the recording paper, so
It will look like 8 (dotted chain line).
ここで記録紙の巻きぐせを取るには２つの動作が必要で

るものではない。Furthermore, the slip rollers 12, 13 consist of metal rollers. The recording paper conveyance speed of the slip rollers 12 and 13 is 10 to 20% faster than that of the grip rollers 9 and 10 and the conveyance rollers 2 and 6. For that reason,
When the leading edge of the received image is applied to the grip rollers 9, 10 and the recording paper handling member 11 and is sandwiched between the slip rollers 12, 13, the curl removal operation is started. That is, the slip rollers 12 and 13 have a faster recording paper conveyance speed than the grip rollers 9 and 10, and the material of the grip rollers 9 and 10 is metal and rubber, whereas the slip rollers 12 and 13 are made of metal. and because it is made of metal,
The coefficient of friction is lower than that at the grip rollers 9 and 10, and even if the presser pressure is the same, the force at which the receiving drawing paper is pressed is stronger at the grip rollers and slip rollers 12 and 13.
The grip roller 9, 1 increases the recording paper conveyance speed by 10 to 20%.
0, but the conveyance speed of the received drawing paper is determined by the speed of the grip rollers 9 and 10. Therefore, the slip rollers 12 and 13 pull the receiving paper while slipping, which gives tension to the receiving paper, and in cooperation with the recording paper handling member 11, the recording paper It has the effect of removing curls. Curling can be removed with such a simple configuration. Note that the configuration consisting of the recording paper handling member 11, grip rollers 9, 10, and slip rollers 12, 13 may be placed at any position on the recording paper conveyance path of the receiver, and is not adopted in this embodiment. .

As is clear from the above embodiments, the present invention realizes an excellent recording paper decurling device that can remove curls from recording paper with a simple configuration and arrange it in the correct order on a tray. It is something.
