Description

Detailed Description of the Invention

The present invention relates to a continuous paper conveying method for a recording apparatus, particularly during loading and conveying, and a recording apparatus for carrying out this conveying method.

[0001]

2. Description of the Related Art In a recording apparatus, while a recording head is running in the axial direction of a platen, a plurality of recording wires of the recording head are struck via an ink ribbon onto a sheet located on the front peripheral surface of the platen. There is a dot impact printer that records an image on this sheet.

In such a printer, a continuous paper as a sheet is conveyed from a push tractor unit arranged at the rear of the printer through a platen to a space between the platen and the recording head. The auxiliary plate is pressed against the platen. In this state, an image is recorded on the continuous paper by the recording head.

The auxiliary plate is for pressing the continuous paper against the platen to improve the recording accuracy of the recording head, and for preventing the generation of noise by hitting the continuous paper on which the recording wire of the recording head is lifted.

In a printer having such an auxiliary plate, FIG. 4 shows control for conveying continuous paper to a recording start (print start) position.

That is, the control device of the printer reads the paper-out determination value n for determining the paper-out state when, for example, the loading button is operated (S100). This paper-out determination value n is a drive motor (PF motor: pulse motor) for driving the platen, push tractor unit, etc.
It is specified by using the pulse number of.

Next, the control device determines whether or not the sheet detection sensor arranged on the sheet conveying path between the push tractor unit and the platen has detected the leading edge of the continuous paper (S101).

When the sheet detection sensor detects the leading edge of the continuous paper and determines that the continuous paper is present, the controller rotates the drive motor (PF motor) forward for p pulses and further forwards q pulses for continuous paper. Are conveyed in the forward direction (S102).

By the normal rotation of the p pulse, the continuous paper is conveyed from the sheet detection sensor until the leading edge of the continuous paper reaches the recording start (printing start) position. Further, by the q-pulse forward rotation, the leading edge of the continuous paper is conveyed in the forward direction by the slack removal correction value beyond the recording start position.

Next, the control device controls the drive motor (PF).
The motor) is reversed by q pulses to remove the slack of the continuous paper, and further r pulses are reversed (S103).

The reverse rotation of the r pulse is for securing a backlash removal correction value for removing the backlash that occurs in the gear train when the drive motor is switched from the reverse rotation to the forward rotation. Due to the reverse rotation of the r pulse, the leading edge of the continuous paper is conveyed in the reverse direction beyond the recording start position by the backlash removal correction value.

Thereafter, the control device rotates the drive motor (PF motor) forward by r pulses to convey the continuous paper in the forward direction (S104), removes the backlash of the gear train, and removes the continuous paper. Position the tip at the recording start position.

On the other hand, in step S101, when the sheet detection sensor does not detect the leading edge of the continuous paper and the control device determines that there is no paper, the control device causes the drive motor (PF motor) to normally rotate by one pulse. (S105), the paper out determination value n is subtracted by one pulse (S106).

Next, the control device determines whether or not the paper-out determination value n is positive (S107), the process proceeds to step S101 when n> 0, and the push tractor unit is activated when n≤0. It is determined that there is no continuous paper (S10).
8).

However, in the continuous paper conveyance control as described above, in step S102,
When the leading edge of the continuous paper is conveyed to the recording start position, the leading edge of the continuous paper jams near the auxiliary plate and causes a paper jam, mainly due to slack when the continuous paper hits the auxiliary plate. There is a fear. In particular, this tendency is remarkable in continuous paper having a thin paper thickness and a weak stiffness.

2. A tractor unit mounting part and a discharging unit mounting part (not shown) to which the discharging unit 13 can be mounted respectively are provided.

The push tractor unit 12 shown in FIGS. 1 and 2 sends the continuous paper as the sheet S to the sheet conveying mechanism section 23, and the sheet supply guide 34 makes the sheet S a sheet S.
The individual cut sheets are supplied to the sheet conveying mechanism unit 23 one by one (in the case of single cut copy paper, one by one). Further, the discharge unit 13 pulls out the continuous paper or the cut sheet from the sheet conveying mechanism section 23 to the outside of the printer 10.

That is, as shown in FIG. 2, the rotation of the tractor belt 26 of the push tractor unit 12 causes
Due to the action of the pin 27 of the tractor belt 26, the continuous paper is guided to the sheet guide 22 of the sheet conveying mechanism section 23, and passes through the sheet conveying path 28 formed between the sheet guide 22 and the platen 21 to cause the platen 21 to move. , And is fed in the direction of arrow α. When the push tractor unit 12 is not in operation, it is possible to feed the cut sheets one by one (or one by one) from the sheet feeding guide 34 to the front of the platen 21 via the sheet conveying path 28.
Further, by the rotation of the discharge roller 29 of the discharge unit 13, the continuous paper or the cut sheet on which characters and the like are recorded by the recording head 18 is pulled out from the platen 21 of the sheet conveying mechanism portion 23 in the arrow β direction, as described later. . As a result, the continuous paper or the cut sheet is conveyed in the sub-scanning direction orthogonal to the main scanning direction, which will be described later, of the carriage 19.

The carriage 19 shown in FIG. 1 is slidably inserted in a carriage guide shaft 24 and carries a recording head 18. Since the carriage guide shaft 24 is arranged parallel to the platen 21, the carriage 19
Are the platen 21 and the carriage guide shaft 24.
It is provided so as to be movable (running) in the main scanning direction that coincides with the axial direction of.

The carriage 19 is guided by the carriage guide shaft 24 through the timing belt 30 (FIG. 2) by the forward or reverse rotation of a carriage drive motor (not shown), and travels leftward or rightward in FIG. 1 in the main scanning direction. It

The recording head 18 has a large number of recording wires, and the ink ribbon 31 is located in front of the recording wires in the protruding direction. While the recording head 18 travels in the main scanning direction together with the carriage 19, the recording wire is ejected and hits the ink ribbon 31, so that the ink ribbon 31
The ink is attached to a sheet S (continuous paper or cut sheet) conveyed between the platen 21 and the ink ribbon 31, and an image including characters is recorded on the sheet S.

In this recording operation by the recording head 18, one line of recording is performed by the recording wire of the recording head 18 while the carriage 19 travels leftward or rightward in the main scanning direction, and each time one line of recording is performed. If the sheet S is continuous paper, the sheet conveying mechanism unit 2 shown in FIG.
The platen 21 of FIG. 3, the push tractor unit 12, and the discharge unit 13, and when the sheet S is a single-cut sheet, the platen 21, the driven roller 25, and the discharge unit 13 of the sheet transport mechanism unit 23 respectively store the sheet S. It is carried out by transporting a fixed amount (usually the space between lines) and repeating these operations.

Reference numeral 32 shown in FIG. 2 is formed so as to open between the base frame 14 and the sheet guide frame 15, and the sheet conveying mechanism portion 23 is provided from below the printer 10.
A bottom sheet supply port for supplying the sheet S into the inside.

The sheet S driven by the platen 21, the push tractor unit 12, and the discharge unit 13 is driven.
Control of the carriage and the recording operation of the carriage 19 and the recording head 18 by the recording wire is performed by the control board unit 33 (FIG. 2) as a control device. The control board portion 33 is disposed, for example, below the sheet guide frame 15 behind the printer body 11.

As described above, the continuous paper SR as the sheet S
When the sheet is conveyed, the driven roller 25 is separated from the platen 21, the conveying force is not applied to the continuous paper SR from the driven roller 25 and the platen 21, and the conveying force is applied to the continuous paper SR by the push tractor unit 12. The continuous paper SR to which the transport force is applied by the push tractor unit 12 in this manner is transported from the push tractor unit 12 through the sheet transport path 28 to between the platen 21 and the recording head 18, and the recording by the recording head 18 is performed. Although it is conveyed to the start (printing start) position, it is pressed against the platen 21 by the auxiliary plate 40 arranged on the exit side of the sheet guide 22 and in front of the recording head 18.

The auxiliary plate 40 presses the continuous paper SR against the platen 21 to improve the recording accuracy of the recording head 18, and at the same time, the recording wire of the recording head 18 hits the continuous paper SR which has been lifted up to generate noise. To prevent.

Further, the auxiliary plate 40 is constructed so that the frictional resistance between the auxiliary sheet 40 and the continuous sheet SR becomes low when it comes into contact with the continuous sheet SR. Specifically, the surface of the auxiliary plate 40 is subjected to a surface treatment for reducing the frictional resistance, or the auxiliary plate 40 itself is made of a material having a low frictional resistance. Since the frictional resistance between the auxiliary plate 40 and the continuous paper SR is configured to be low in this way, paper jam when the leading end of the continuous paper SR hits the auxiliary plate 40 is suppressed.

Further, in the auxiliary plate 40, the angle θ formed by the tip of the abutting continuous paper SR makes this continuous paper SR an auxiliary plate 4.
The angle is set such that 0 can be conveyed in the forward direction. Also by configuring the above-described angle θ as described above, paper jam when the leading edge of the continuous paper SR hits the auxiliary plate 40 is suppressed.

In FIG. 2, reference numeral 41 is a sheet detection sensor for detecting the leading edge of the continuous paper SR and causing the control board unit 33 to determine the presence or absence of the continuous paper SR. The sheet detection sensor 41 is used in the push tractor unit 1
2 and the platen 21.

The control board portion 33 causes the continuous paper SR to be conveyed in the forward direction to the extent that the leading edge thereof strikes the auxiliary plate 40, is stopped there, and is then conveyed in the reverse direction. It is controlled so that it is conveyed in the forward direction. Here, the continuous paper SR is conveyed in the forward direction by the continuous paper S.
R from the push tractor unit 12 to the recording head 1
8 and the platen 21 and is the direction of conveyance to the discharge unit 13 side, and the reverse direction conveyance is the conveyance in the direction opposite to the forward direction conveyance.

As shown in FIG. 3, the control board unit 33 reads the paper-out determination value N for determining the paper-out state when, for example, the loading button on the operation panel is operated (S1). The paper-out determination value N is the platen 21,
It is defined using the number of pulses of a drive motor (PR motor: pulse motor) that drives the push tractor unit 12 and the discharge unit 13.

Next, the control board unit 33 determines whether or not the sheet detection sensor 41 installed on the conveyance path between the push tractor unit 12 and the platen 21 detects the leading edge of the continuous paper SR ( S2).

The control board section 33 includes a sheet detection sensor 41.
Detects the leading edge of the continuous paper SR and determines that there is paper,
The drive motor (PR motor) is normally rotated by P pulse,
The continuous paper SR is conveyed in the forward direction from the position of the sheet detection sensor 41 to the position where the continuous paper SR abuts the auxiliary plate 40 (S3).

Next, the control board unit 33 reverses the driving motor by Q pulses and then reverses it by R pulses, and the continuous paper S is fed.
R is conveyed in the reverse direction (S4). The Q pulse is a slack removal first correction value, and the reverse rotation of the drive motor of the Q pulse removes the slack accumulated on the continuous paper SR until the leading edge of the continuous paper SR hits the auxiliary plate 40.

The reverse rotation of the R pulse is to secure a backlash removal correction value for removing the backlash generated in the gear train when the drive motor (PF motor) is switched from reverse rotation to normal rotation. The gear wheel train is for decelerating and transmitting the driving force of the drive motor to the platen 21, the push tractor unit 12, and the discharge unit 13.

Next, the control board portion 33 rotates the drive motor (PF motor) forward for (Q + R) pulses to continuously feed the continuous paper S.
R is conveyed in the forward direction, and the leading edge of the continuous paper SR is abutted against the auxiliary plate 40 (S5). By the normal rotation of the drive motor for the R pulses, the backlash of the gear train that occurs when the drive motor is switched from the reverse rotation of step S4 to the normal rotation of step S5 is removed.

The control board unit 33 continuously rotates the drive motor forward by S pulses to convey the continuous paper SR in the forward direction, and starts recording (printing from the position where the leading end of the continuous paper SR hits the auxiliary plate 40). The continuous paper is moved until it reaches the (start) position (S5).

Since the slack generated in the continuous paper SR in step S4 has been removed, in step S5, when the leading edge of the continuous paper SR hits the auxiliary plate 40, it is properly positioned with respect to the auxiliary plate 40. (For example, the angle formed by the continuous paper SR with respect to the auxiliary plate 40 is an angle at which the continuous paper SR can be conveyed forward from the auxiliary plate 40 in the forward direction).
Therefore, the continuous paper SR is smoothly conveyed in the forward direction without causing a paper jam.

The control board unit 33 further rotates the drive motor in the normal direction by T pulses to convey the continuous paper SR in the forward direction (S5). This T pulse is the slack removal second correction value, and the continuous rotation of the continuous paper S by the normal rotation of the drive motor of this T pulse.
The continuous paper is conveyed in the forward direction so that the leading edge of R reaches the position beyond the recording start position by the second sag removal correction value.

Next, the control board unit 33 controls the drive motor (P
The F motor) is reversed by (T + R) to convey the continuous paper SR in the reverse direction (S6). By the reverse rotation of the T pulse of the drive motor, the slack generated on the continuous paper SR by that time,
Particularly, when the continuous paper SR passes through the conveyance path between the auxiliary plate 40 and the platen 21, the slack generated in the continuous paper SR is removed.

The reverse rotation of the R pulse of the drive motor is a backlash removal correction value for removing the backlash generated in the gear train when the drive motor is switched from the reverse rotation to the normal rotation as described above.

After that, the control board unit 33 causes the drive motor (PF motor) to normally rotate by R pulses to convey the continuous paper SR in the forward direction, remove the backlash of the gear train, and remove the continuous paper SR. The tip is positioned at the recording start position (S7).

On the other hand, when the sheet detecting sensor 41 does not detect the leading edge of the continuous paper SR in step S2 and the control board portion 33 determines that there is no paper, the control board portion 33 is detected.
Causes the drive motor (PF motor) to rotate in the normal direction for one pulse (S8), and subtracts the paper-free determination value N for one pulse (S8).
9).

Next, the control board unit 33 determines the paper-out judgment value N.
Is positive (S10), the process proceeds to step S2 when N> 0, and when N ≦ 0, it is determined that the continuous paper SR does not exist in the push tractor unit 12 (S11). .

With the above-mentioned configuration, the following effects (1)-(3) are obtained according to the above-described embodiment.

The control board portion 33 conveys the continuous paper SR in the forward direction until the leading edge of the continuous paper SR hits the auxiliary plate 40, stops it there, and then conveys it in the reverse direction by a predetermined amount (reverses the driving motor by Q pulses). Therefore, this continuous paper S
This continuous paper SR is transferred to the auxiliary plate 4 by the conveyance in the opposite direction of R.
It is possible to remove the slack generated in the continuous paper SR until it hits 0. As a result, when the continuous paper SR is conveyed in the forward direction after being conveyed in the reverse direction, the leading edge of the continuous paper SR has an appropriate posture (for example, the angle θ formed by the leading edge of the continuous paper SR and the auxiliary plate 40 is the continuous paper SR Since the auxiliary plate 40 can be abutted against the auxiliary plate 40 in a posture such that the auxiliary plate 40 can be conveyed forward in the forward direction), the continuous paper SR can be recorded near the auxiliary plate 40 at the recording start position without causing a paper jam. Can be transported well.

Since the auxiliary plate 40 has a low frictional resistance with the continuous paper SR, the continuous paper SR after the leading edge hits the auxiliary plate 40 can be smoothly conveyed in the forward direction, and the vicinity of the auxiliary plate 40 can be conveyed. It is possible to prevent the occurrence of paper jams.

The auxiliary plate 40 is a continuous paper SR that has abutted against it.
Since the angle θ formed by the leading end of the continuous paper SR is set to an angle that allows the continuous paper SR to be conveyed forward from the auxiliary plate 40 in the forward direction,
The continuous paper SR whose front end hits the auxiliary plate 40 and is conveyed in the forward direction can be smoothly conveyed without causing a paper jam near the auxiliary plate 40.

Although the present invention has been described based on the above embodiment, the present invention is not limited to this.

For example, in the above embodiment, the continuous paper SR
In the above description, the driven roller 25 is separated from the platen 21 when the sheet is conveyed, and the conveyance force of the platen 21 and the driven roller 25 does not act on the continuous paper SR, but only the conveyance force of the push tractor unit 12 acts. During the transportation of the continuous paper SR, the driven roller 25 located especially on the auxiliary plate 40 side.
The continuous paper SR may be pressed against the platen 21 by means of the push tractor unit 12, and the conveyance force of the platen 21 and the driven roller 25 may be applied to the continuous paper SR. In this case, the following effects are obtained.

Before the auxiliary plate 40, the continuous paper SR is pressed against the platen 21 by the driven roller 25, and the platen 21, the driven roller 25, and the push tractor unit 12 apply a conveying force to the continuous paper SR. During the forward transport (step S5) after the backward transport of the paper SR (step S4), the continuous paper SR can be smoothly transported in the forward direction after the leading edge of the continuous paper SR hits the auxiliary plate 40. The occurrence of paper jam near the plate 40 can be prevented.
