DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a roller recording apparatus having a recording paper supply unit for performing continuous recording on a long recording paper.

[Conventional technology]

As a device configured to perform continuous recording using a long recording paper, a device having a configuration shown in FIG. 4 has been generally used. In FIG. 4, 1 is a recording paper, 21 is a recording table, 22 is a drive roller, 23 is a driven roller, 3 is a recording paper take-up roller, 4 is a recording paper supply roller, and 6 is a recording pen.

In this apparatus, the recording paper 1 pulled out from the recording paper supply roller 4 is nipped by a recording paper drive means composed of a driving roller 22 and a driven roller 23, and the recording paper 1 is recorded by rotating the driving roller 22 in forward and reverse directions. The recording pen 6 is moved back and forth on the table 21, and at the same time, the recording pen 6 is moved in a direction perpendicular to the moving direction of the recording paper 1 for recording, and after the recording is completed, unnecessary recording paper is wound around the recording paper winding roller 3. However, it has several stages in its operation.

The recording operation of this conventional apparatus will be described below with reference to FIGS. In FIG. 5, C1 is the first recording area,
C2 is the second recording area, and H is the recording home point.

, Pulling out the recording paper 1 from the recording paper supply roller 4, sandwiching it between the driving roller 22 and the driven roller 23 on the recording table 21, and setting the leading end of the recording paper 1 on the recording paper take-up roller 3. Shows. Here, reference numeral a1 is a distance from the recording home point H, that is, the contact position of the recording pen 6 to the recording paper take-up roller 3, and is an area where recording is impossible.

Prior to the recording operation, the recording paper 1 is moved further forward by a recording paper drive means composed of a driving roller 22 and a driven roller 23, and the first recording, which is the first recording area of the recording paper 1. The end position of the area C1 is moved to the recording home point H.

Next, according to the image signal, the recording paper driving means is driven to move the recording paper 1 back and forth, and the recording pen 6 is moved in the orthogonal direction, so that recording according to the image signal can be performed in the first recording area C1. .

At this stage of recording, since this kind of device is usually configured to transfer the recording paper 1 at high speed and high acceleration, the recording time can be shortened, so that the recording paper 1 can be operated at this speed sufficiently. The slack portions 43 and 44 of the recording sheet 1 before and after the recording table 21 so as to be able to follow (the slack portion 43 is not formed since the initial recording state is shown in FIG. 5).
Is formed.

When the recording on the first recording area C1 is completed, the recording paper winding roller 3 is then driven by a winding roller driving mechanism (not shown), and the first recording area C1 on which recording has been completed is wound up.

The state shown in FIG. 5 is the same as the state shown in FIG.

In the next state, the recording paper 1 is pulled out by the recording paper drive means. Then, the second recording area C2, which is the second recording area for the next recording, is pulled out, and the end position thereof is moved to the recording home point H. This state is the fifth
Recording is performed in the second recording area C2 in the same manner as in the illustrated state, and thereafter.

Similarly, it is possible to continuously perform recording on a long recording sheet by sequentially repeating the operations shown in FIGS.

[Problems to be solved by the invention]

As described above, in the movement of the recording paper in the conventional apparatus, the recording area to be recorded is drawn out for each recording area by the driving of the recording paper drive means from the recording paper supply section, and therefore the recording paper expands or contracts depending on the use environment during recording. However, there is a drawback that the recording paper that is moved forward and backward by the recording paper drive means provided at both ends of the recording paper is gradually displaced.

[Means for solving problems]

In order to solve the above-mentioned problems, the present invention arranges a recording paper supply unit at the bottom of the apparatus, and installs a slack forming roller on the upper side of the apparatus in front of the line connecting the recording paper supply unit and one end of the recording table. At the same time, the recording paper regulating roller is provided on the rear side of the line connecting the recording paper supply unit and one end of the recording table, below the slack portion forming roller, and the recording paper is driven by the recording paper drive means to cover the recording area for the recording area. When the recording area is moved, at least the recording area for the next recording is pulled out from the recording paper supply section, and when the recording area currently recorded is moved backward during the recording operation, the slack portion is formed. The recording paper portion between the roller and one end of the recording table forms a slack portion between the recording paper regulating roller and the apparatus installation surface.

[Action]

A recording area for the current recording and a recording area for the next recording are always drawn out from the recording paper supply unit.

Therefore, at the stage where the current recording is being performed, the next recording area will be immersed in the surrounding environment, and at the recording stage, the recording environment will be sufficiently adapted to the surrounding environment.

〔Example〕

1 to 3 are explanatory views showing an embodiment of the present invention.

In FIGS. 1 to 3, 1 is a recording paper, 21 is a recording table, 22 is a driving roller, 23 is a driven roller, 3 is a recording paper take-up roller, 4 is a recording paper supply roller, 41 is a recording paper regulating roller, 42 is a slack forming roller, 6 is a recording pen, D1 is the first
A recording area, D2 is a second recording area, and D3 is a recording area.

First, referring to FIG. The recording paper supply unit is composed of the recording paper supply roller 4 and is arranged at the bottom of the apparatus.
The recording paper driving means including a driving roller 22 embedded in the recording table 21 and a driven roller 23 engaged with the driving roller 22 holds the recording paper 1 at both ends.

The drive roller 22 is connected to a paper feed motor (not shown) and is configured to be rotatable in the forward and reverse directions according to an image signal. The pulling out of the recording paper 1 is to pull out the recording paper 1 of a predetermined length from the recording paper supply roller 4, and this is performed by driving a paper feed motor by a paper feed signal from a controller (not shown) and recording. The recording paper is pulled out by a predetermined length by the paper drive means.

As shown in FIG. 2, the recording paper supply roller 4 is arranged at the bottom of the recording device. The slack forming roller 42 is disposed below the recording table 21 at a position substantially facing the recording paper winding roller 3, and the recording paper regulating roller 41 is disposed near the outer lower portion of the slack forming roller 42. Has been done. In this way, the recording paper supply roller 4, recording paper regulation roller
By arranging 41 and the slack forming roller 42,
The recording paper 1 pulled out from the recording paper supply roller 4 is once folded back by the slack forming roller 42, conveyed downward, and then further folded back by the recording paper regulating roller 41.
It is configured to be conveyed to the recording unit. As a result, when the recording paper 1 is moved by the recording paper drive means in the recording paper pull-out mode described later by the recording area related to the current recording, at least the length covering the recording area for the next recording is recorded. It is configured so that it can be pulled out from the paper supply roller 4.

Further, the recording paper regulating roller 41 is provided with a slack portion (reference numeral 43 in FIG. 3) of the recording paper 1 formed by the slack portion forming roller 42 when the recording paper 1 is transported in the front-rear direction at high speed and high acceleration.
(Indicated by) becomes a cushioning member for a large change. That is, when the recording paper 1 is transported in the front-rear direction at high speed and high acceleration, a wavy undulation occurs near the end of the recording table 21, which is transmitted to the recording unit and deteriorates the recording quality.
Although there is a case where the recording paper 1 is bent and comes out of the regular transfer path, in the present invention, the recording paper 1 contacts the recording paper regulating roller 41 provided on the rear side of the recording table 21. Since the recording paper 1 is transferred to the recording unit after coming into contact therewith, the recording paper 1 can be transferred without the wavy undulation generated on the recording paper being transmitted to the recording unit. Can be prevented from coming off.

Next, the operation will be described with reference to FIG. FIG. 3 is a simplified illustration of a linked recording method using the apparatus shown in FIG.

In this embodiment, the length of the recording paper 1 pulled out from the recording paper supply roller 4 is set twice (for example, the recording area D
The length is set to 1) and D2).

Hereinafter, description will be given in the order according to FIG.

In this example, the recording paper 1 is set in the apparatus, the recording paper pull-out mode is set, and the recording paper for the recording area (that is, the first recording area D1) related to the current recording is moved before the recording operation. Shows. The first on this recording paper 1
The portion of the recording area D1 indicated by reference numeral d2 indicates the end position of the recording area, and the reference numeral d1 indicates the start position of the recording area. In this recording paper pull-out mode, the recording paper drive means moves the recording paper 1 from d2 to d1. At this time, the second recording area D2 is pulled out from the recording paper supply roller 4.

In order to record a predetermined image on the recording paper 1 in the recording operation mode, the drive roller 22 of the recording paper drive means is rotated in the forward and reverse directions to move the recording paper 1 in the front-rear direction and the recording pen. 6 is moved in a direction orthogonal to the moving direction of the recording paper 1, and recording is performed in the first recording area D1.

In this case, as shown in the figure, the slack portions (reference numerals 43 and 44) of the recording paper 1 are formed on both sides of the recording table 21, and even when the recording paper 1 is transported at high speed and high acceleration, it is sufficient. It is configured to follow.

At this time, the second recording area D2 pulled out from the recording paper supply roller 4 in the recording paper pull-out mode forms a slack portion 43, and the slack portion 43 is held by the slack portion forming roller 42.

When the recording of the first recording area D1 is completed, the recording paper take-up roller 3 is operated by a take-up roller driving mechanism (not shown), and the first recording area D1 on which the recording is performed is taken up (FIG. 3). Further, from this state, in the recording paper pull-out mode, the recording paper driving means, instead of the winding roller driving means, moves the recording paper 1 by the second recording area D2.

As a result, the second recording area D2 is further recorded in the recording table.
It is driven until the start position d3 of the recording area D2 reaches the recording home point H on the recording head 21. This state is the same as the state shown in FIG. 3, and is a state in which preparation for recording in the second recording area D2 has been completed. At this time, the third recording area D3 for the next recording is pulled out from the recording paper supply roller 4.

From this state, the second recording area D2 is set as the recording operation mode.
Although the recording is performed on the upper side, since the second recording area D2 is immersed in the surrounding environment while the recording is performed on the first recording area D1, expansion and contraction may occur during the recording operation. Absent.

Continuous recording is performed by sequentially repeating the following steps.

〔effect〕

As described above, according to the present invention, in continuous recording using a long recording sheet, by moving the recording area related to recording by the recording sheet driving means prior to the recording operation,
Since the recording area is always pulled out from the recording paper supply unit the next time, recording can be performed after the recording paper has been sufficiently adjusted to the operating environment, so the recording paper does not expand or contract during recording and the recording paper does not move. The present invention has an effect that it can operate accurately and can perform continuous recording with high accuracy.
