Abstract

PURPOSE:To transport a cut form to a printing part correctly and thereby to print data in parallel with the rules of a document and a journal by providing the first transport device consisting of paired feed roller and pressure roller and the second transport device consisting of paired feed rollers and pressure rollers. CONSTITUTION:If a continuous form book 1 is introduced by an operator until it comes in contact with nip parts 16 of rollers 10, 15 on the second transport device, sensors 8, 11 detect the passage of the book 1 and the drive of a solenoid 7 stops due to a detection signal from the sensors 8, 11. Then, a pressure roller 5 is allowed to come in contact with a feed roller 2 under pressure. If the tip of the book 1 is put in contact obliquely with a roller shaft of the second transport device by an opera tor, a motor 4 for the first transport device is driven to transport the book 1 further few steps by the transport action of transport rollers 2, 5. Consequently, the tip of the book becomes slightly swollen between upper and lower guide plates 10. This action results in the generation of a rotating action of an obliquely running book 1 with paired rollers 2, 5 on a roller shaft 6 acting as a fulcrum. Subsequently, the tip of a form is forced to maintain itself in equilibrium with the nip part 16 of the second transport device.

A conventional continuous form conveyance device and its control method are shown in Figure 4 (
As shown in a) and (b), the first conveying means for taking in continuous forms 50 (hereinafter referred to as continuous forms) is a drive motor. A solenoid 56 is connected to the end of the shaft 55 of the pressure roller 54 from the pressure roller 54 which is in pressure contact with the plurality of feed rollers 53 via the belt 52, and the solenoid 56 is connected to the end of the shaft 55 of the pressure roller 54. It has a structure in which it is separated from the feed roller 53. 57 is a sensor that detects the presence or absence of paper, 58 is a cutting blade, and 59 is a sensor that confirms that the continuous book 50 after cutting has been reliably cut. Next, a plurality of feed rollers 62 are connected to a drive motor 60 as a second conveyance means via a belt 61, a pressure roller 63 is pressed against these rollers, and a sensor 64 detects the leading end of the continuous book 50. Paper guidance is performed by guide plates provided at the top and bottom, and the guide plates 65 have side edges slightly wider than the continuous book width.

In the above-described structure, the conveyance control of the continuous book 50 begins with the pressure rail 54 of the first conveyance means being in a state separated upwardly by the drive of the renoid 56 in the initial state of the apparatus.

Next, the operator inserts the continuous book 50 until it abuts the nip portion 68 of the roller of the second conveying means.
Sensors 57 and 59 detect the passage of the continuous book, and in response to this detection signal, the driving of the solenoid 56 is stopped, and the pressure roller 54 holds the continuous book 50 and comes into pressure contact with the feed roller 53.

Thereafter, the continuous book 50 is conveyed by the first and second conveying means, the leading end of the continuous book is detected by the sensor 64, and the conveyance amount is controlled so that the first perforation is aligned with the position of the cutting blade 58. Then, a cutting operation is performed, and the cut medium is conveyed as a single sheet to a printing section where a printing operation is performed. In this way, the subsequent continuous book 50 after being cut is held between the first conveying means, so that the above-mentioned operation is repeated.

By controlling according to the procedure described above, the skew of the form in the conveying direction that occurs when setting continuous forms or cutting is corrected, so that the device can print at a predetermined position on the form in subsequent printing operations. It provides:

[Effect]

The present invention having the above features uses a pair of conveyance rollers as the first conveying means for taking in the continuous book, so that the center of the continuous book width can be held at one point, and a slight rotational action can be applied to the continuous book. Therefore, even if the leading end is in a skewed state, the second conveyance means is composed of a plurality of conveyance rollers, so that the continuous book is brought into contact with the nip portion of this conveyance roller, and after the contact Furthermore, since the paper is forcibly transported by the first transport means, the amount of skew at the leading edge of the continuous book becomes parallel to the roller axis of the second transport means due to the rotational action.

〔Example〕

Hereinafter, the present invention will be explained in detail based on the drawings of FIGS. 1 to 3.

FIG. 1 is a schematic side view of the form conveyance device, FIG. 2 is a plan view thereof, and FIGS. 3(a) to 3(d) are side views of essential parts showing a conveyance control procedure regarding skew correction.

In FIGS. 1 and 2, 1 is a continuous book having perforations at predetermined intervals, and 2 is a feed roller connected to a drive motor 4 via a belt 3. A pressure roller 5 is connected to an end of a roller shaft 6 to which a renoid 7 moves the pressure roller 5 toward and away from it. 8 is a sensor for detecting the presence or absence of a continuous book;
Reference numeral 9 indicates a cutting blade, and 10 indicates a guide plate for the paper conveyance path, which is slightly wider than the paper width and has both side edges. 1
1 uses a sensor to confirm that the continuous book 1 after cutting is securely cut. Reference numerals 12 and 15 designate second conveying means formed from a plurality of pairs; 12 is a feed roller, which is connected via a belt 13 to a motor 14 serving as a drive source; A pressure roller 15 is in pressure contact with the feed roller l2. 16
17 is the nip portion of the rollers 12 and 15 of the second conveying means, and 17 is a paper position detection sensor that detects the leading end of the continuous book 1 and manages the amount of conveyance to align the perforation with the position of the cutting blade 9. 18 is a print head, and 19 is a platen.

Next, the operation of this embodiment having the above configuration will be explained.

First, in the initial state of the device, the solenoid 7 is driven, and the pressure roller 5 is separated from the feed roller 2 and is waiting at the 5' position.

Now, the operator inserts the continuous book l until it contacts the nip l6 between the rollers 12 and 15 of the second conveying means. Therefore, the sensors 8 and l1 detect the passage of the continuous book 1, and in response to the detection signal, the drive of the solenoid 7 is stopped after a set time of a timer (not shown), and the pressure roller 5 is brought into pressure contact with the feed roller 2. When the operator inserts the form so that the leading edge of the form comes into oblique contact with the roller shaft of the second conveying means as shown in FIG. 2, the motor 4 of the first conveying means is driven in FIG. 3(a). Then, the continuous book 1 is further conveyed several steps in the direction of arrow by the conveying operations of the conveying rollers 2 and 5. As a result, a slight bulge (A) is generated at the leading edge of the form between the upper and lower guide plates 10 (not shown). Due to this operation, the skewed state of the continuous book is controlled by the pair of rollers 2 and 5 on the roller shaft 6 acting as a fulcrum and exerting a rotating action.
The leading edge of the paper is forced to remain parallel to the nip portion 16 of the second conveying means.

Next, in FIG. 3(b), the rollers 2 and 5 of the l-th conveying means are kept in a stationary state, and the rollers 12 and 15 of the second conveying means are rotated by the motor l4, and the continuous book 1 is held between the rollers 1 and 5 for a short distance. Transport it and stop it. Therefore, the amount of bulge (b) at the leading edge of the paper becomes smaller.

Next, in FIG. 3(C), the pressure roller 5 is separated from the feed roller 2 by applying a drive to the solenoid 7 of the first conveyance means. As a result, the bulge (b) of the continuous book 1 is released and escapes in the opposite direction to the traveling direction of the continuous book.

Next, in FIG. 3(d), the solenoid 7 of the first conveying means
, the pressure roller 5 is brought into pressure contact with the feed roller 2 again, and the perforation position of the continuous book 1 is conveyed to the position of the cutting blade 9.

Next, skew correction control when a cutting operation is performed after inserting a continuous book will be explained. The sensor 17 detects the tip of the continuous book 1, and the perforation line is set in advance to match the cutting position by feeding the continuous book 1 by a predetermined amount of conveyance. During the cutting operation, both the rollers of the first and second conveying means are in a stopped state.

Therefore, when the continuous book l is cut by the cutting blade 9, the first conveyance means holds the center position of the paper width with only one pair of rollers, so the load on the cutting blade 9 is directed from the edge of the continuous book to the center. (The height of the cutting edge is different on the left and right sides) A rotating action is generated at the center of the roller. Therefore, after the cutting operation is completed, the leading end of the subsequent continuous roll 1 is conveyed to the nip portion 16 of the second conveying means while maintaining an oblique state during the next conveying operation. In this way, the correction control procedure repeats the operations shown in FIGS. 3(a) to 3(d) explained in connection with the above-mentioned continuous book insertion.

〔Effect of the invention〕

As explained above, according to the present invention, the first conveying means is
By installing a pair of transport rollers in the center of the paper width, it is possible to rotate the continuous book, so it is possible to rotate the continuous book. Since it is possible to correct and control the skew of the subsequent sheet, the cut sheet can be conveyed correctly to the printing unit, and it can be printed parallel to the ruled lines of the form, making it easy to see. Good.
