Abstract

PURPOSE:To enable the form alignment to be accomplished by a simple mechanism when the form is dislocated between a feed roller and a take-up roller by arranging a form alignment means which sets the form in a line by pulling it from both sides so as to expand it. CONSTITUTION:A sheet of recording paper 8 is expanded between a recording paper feed roller 10 and a recording paper take-up roller 11 allowing a drive roller 5 to be disengaged from a pinch roller 6. That is, a form alignment signal allows both a control means and ROM 19 to output the form alignment signal permitting not only the drive roller 5 to be released from the pinch roller 6 where the disengagement condition is provided, but also the recording form to be expanded with a recording paper take-up motor 111 activated. And the disengagement between the rollers 5 and 6 permits the roller 5 to be connected with a shaft 12 allowing the roller 6 to be connected with a shaft 13. An operational shaft which is connected with the shaft 13, is driven up and down by means of both cams and a cam drive motor. Accordingly, the form alignment signal allows the cam drive motor to rotate by the stated angle permitting the form alignment to be actually accomplished. Thus, this configuration prevents the form from being dislocated.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a recording apparatus in which recording sheets are inserted and driven by a drive roller and a pinch roller, and particularly to an automatic aligning device for the recording sheets.

[Conventional technology]

FIG. 4 shows a general configuration of a recording apparatus that inserts and drives recording paper using a drive roller and a pinch roller.

In Figure 4, l is a recording pen, 2 is a carry, 7ji, 3
is a belt, 4 is a pen drive motor, 5 is a drive roller, 6 is a pinch roller, 7 is a recording paper feed motor, 8 is a recording paper, 9 is a recording table, 10 is a recording string supply roll, 11
1 is a recording and IE take-up roll, and 12 is a drive roller shaft.

Recording paper 8 pulled out from recording paper supply roll 10 passes over recording table 9 and is wound up by recording paper winding roll 11 . The recording paper 8 on the recording table 9 is inserted into a drive roller 5 embedded in the recording table 9 and a pinch roller 6 that engages with the drive roller 5. The drive roller 5 is driven under the control of a recording paper feed motor 7. Therefore, the recording paper 8 is moved by the recording paper feed motor 7.
A controlled feeding operation is performed.

A recording pen l is fixed to a carriage 2.

The carriage 2 is engaged via a belt 3 to a pen drive motor 4. Therefore, the recording pen 1 is driven as desired by the controlled pen drive motor 4.

A desired recording is performed on the recording paper 8 by relative movement of both, that is, the recording paper 8 and the recording pen l.

To further explain the operation of this type of recording apparatus, first, as a pre-recording step, the recording paper 8 is moved by a recording paper feeding means (recording paper feeding motor 7) consisting of a drive roller 5 and a pinch roller 6 in an amount necessary for recording. Supply roll I
Pull out from O. At this time, the recording paper winding roll 1
Since the recording paper winding motor 111 (recording paper winding motor 111) does not perform a winding operation, a sagging portion is formed on the recording paper 8 as shown in FIG. This hanging portion is necessary to smoothly transport the recording paper 8 in the front-back direction (indicated by the arrow in the figure) during the recording operation.

At this point, the recording operation begins. The recording pen 1 and the recording paper 8 are driven by the arrival of the recording signal, and two-dimensional recording is performed on the recording paper 8.

When recording is completed, the recording paper winding motor 111 that engages with the recording paper winding roll 11 operates, and the recording paper 8
is wound up on the take-up roll 11.

By repeating these operations, a long recording paper can be used.

However, as mentioned above, a device that inserts and drives a recording paper using a drive roller and a pinch roller is usually provided with recording paper driving means each consisting of a drive roller and a pinch roller at both ends of the recording paper. .

Incidentally, in this case, if there are variations in the recording paper driving means provided at both ends, or if uneven feeding occurs at both ends due to recording conditions, etc., sheet misalignment may occur. To eliminate this drawback, a typical conventional automatic alignment device for recording sheets of this type is the device described in Japanese Patent Application Laid-Open No. 55-93016.

This device is equipped with a sensor that detects the inclination of the recording paper, a pivot that presses only one point on the recording paper, and a means for rotating the recording paper around this pivot. By making these elements interact, the recording paper This automatically aligns the files.

[Problem that the invention seeks to solve]

In any case, conventional recording paper automatic alignment devices detect the inclination of the recording paper and are equipped with a recording paper drive means that compensates for this inclination, but these means have complex structures and are not compatible with each other. There was also the drawback that complex motion control was required for the relationship.

The present invention has been made to eliminate such drawbacks.

[Means for solving problems]

In order to achieve this object, the present invention is provided with a sheet aligning means that stretches and aligns the recording sheets.

[Effect]

Next, the present invention will be explained in detail with reference to FIG.

Recording paper supply roll 10 and recording paper take-up roll 1
When paper misalignment occurs between the
If the recording sheets 8 are stretched by applying tension from both sides, the recording sheets 8 will be aligned as shown in FIG. 3 fb).

The present invention utilizes this effect.

〔Example〕

FIG. 1 is a configuration explanatory diagram showing an embodiment of the present invention, in which a sheet alignment operation is performed.

First, normal recording operations are almost the same as those of conventional devices.

That is, upon arrival of the recording signal, the control means 18 and I? 0
M19 performs predetermined arithmetic processing, and based on this processed signal, a pen up-down signal that performs pen up-down control of the recording pen 1, and a carriage drive that transports the carriage 2 carrying the recording pen 1 forward and backward in a predetermined direction. A carriage drive signal that controls the motor 4, a paper feed signal that controls the paper feed motor 7 that transports the recording paper 8 forward and backward in a direction perpendicular to the carriage transport direction, and a paper feed signal that controls the paper feed motor 7 that transports the recording paper 8 in a direction perpendicular to the carriage transport direction. It outputs a winding signal that controls a paper winding motor 111 that winds up the paper 8. Desired recording can be obtained by executing these control signals in a predetermined sequence.The sheet alignment operation of the present invention shown in FIG. 1 will be explained.

In the IE arrangement shown in FIG. 1, the recording paper 8
is expanding. In this case, the drive roller 5 and the pinch roller 6 are in a non-engaged state. That is, in response to the sheet alignment signal, the control means 18 and the r20M19 output a banknote row signal, disengage the driving roller 5 and the pinch roller 6 to bring about a disengaged state, and operate the recording paper winding motor 111 to perform recording. Expand paper 8. FIG. 2 shows a configuration for bringing the drive roller 5 and pinch roller 6 into a disengaged state. In FIG. 2, the drive roller 5 is connected to a drive roller shaft 12. In FIG. The pinch roller 6 is mounted on a pinch roller shaft 13, and has a configuration in which an operating shaft 14 coupled to the pinch roller shaft 13 is driven up and down by a cam 16 and a cam drive motor 17. Therefore, the paper alignment signal causes the cam drive motor 17 to rotate by a predetermined angle, thereby holding the pinch roller 6 in the upper position and creating a disengaged state.

By the way, as a condition required for stretching the recording paper 8 and aligning the recording paper 8 in this manner, it is important that the recording paper 8 be held at a proper position when the recording paper 8 is stretched.

In the apparatus according to the embodiment of the present invention shown in the first UXJ, the reference position of the recording paper 8 is determined by the attachment position of the recording paper supply roll lO forming the recording paper supply section and the mounting position of the recording paper winding roll 11 forming the recording paper stock section. It is determined by However, in this case, the recording paper supply roll 10
If the recording paper 8 between the recording paper winding roll II and the recording paper winding roll II is wound on the recording paper winding roll 11 in a misaligned manner due to a winding failure, for example, it cannot be properly aligned as shown in FIG. . In order to prevent this, it is important that the recording paper 8 is appropriately wound around the recording paper winding roll 11. Therefore, in the present invention, the first
As shown in the figure, when the starting end of the recording paper 8 is loaded onto the recording paper winding roll 11, a first alignment mark 81 is provided on the recording paper 8 to ensure that the recording paper 8 is loaded correctly, and a recording table 9 that matches this is provided. A second alignment mark is provided at a predetermined position on the top. By aligning the first alignment mark and the second alignment mark to align the starting edge of the recording paper 8 with the recording paper 1 [by attaching it to the take-up roll 11, there will be no winding misalignment and the paper will always be properly aligned. It can be performed.

〔Effect of the invention〕

As described above, the present invention has the advantage of being able to align sheets with a simple configuration.
