Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a recording apparatus for recording data input from a personal computer, a word processor, an electronic typewriter, a facsimile apparatus, etc. on a recording sheet, and relates to at least two or more sheets fed in parallel. The present invention relates to a device capable of recording data on a recording sheet.

[0002]

2. Description of the Related Art In recent years, the performance of personal computers has been remarkably improved, and the processing speed has been considerably increased. In addition, the spread of the Internet has been remarkable, and various kinds of information have become easily available.

[0003] In such a situation, it is desired to increase the speed of the recording device as the output device, and there is a problem how to output a large amount of information quickly.

Here, as a conventional recording apparatus, a feeding means for separating and feeding stacked recording sheets one by one,
Some recording apparatuses include a recording unit that forms an image on a fed recording sheet, a conveyance unit that accurately conveys the recording sheet that is being recorded, and a discharge unit that discharges the recorded recording sheet.

[0005] In the recording apparatus having such a configuration, in order to increase the processing speed, the image recording speed of the recording means is increased, and the speed of the conveying means and the discharging means is increased. However, even if the operating speeds are increased in this way, there is a limit to increasing the total processing speed since recording is performed one by one.

Therefore, in order to dramatically improve the total processing speed, there is a printer in which at least two sheets are fed in parallel and recording is performed simultaneously. For example, in the case of a device capable of feeding up to A4 size sheets, if the width of A6 or postcards is less than half, even if two sheets are stacked in parallel, it is possible to cope without changing the device size. Some ideas have been invented.

For example, Japanese Utility Model Registration No. 1602264 proposes a paper feeder capable of feeding two small papers in parallel by one operation, and capable of directly feeding large papers as usual. I have. Also, Japanese Patent Application Laid-Open No. 5-286599
In this publication, a recording apparatus is also described in which two recording sheets are fed in parallel to perform recording.

However, when two sheets are fed in parallel, there are the following problems.

That is, when two sheets are fed in parallel, even if feeding is started at the same time, a delay due to slippage of the feeding means,
There is a case where a difference occurs in arrival at the transport roller due to a difference in timing of rush to the transport roller or the like, and two sheets may not reach the transport roller at the same time. In such a case, if the recording is directly performed on the two fed recording sheets, even if one of the recording positions is appropriate,
The recording position of the other recording sheet is not always an appropriate position.

In order to solve such a problem, Japanese Patent Application Laid-Open No. Hei 5-286599 discloses a method in which a friction clutch is attached to a feeding roller, two sheets are fed at the same time, and a sheet that arrives at a conveying roller with a delay. The feeding roller is rotated until the leading end of the feeding roller contacts the conveying roller. The paper that has reached the transport roller first is held by the friction clutch with the leading end of the paper abutting the transport roller.

[0011] In this manner, by driving the transport roller after the leading edge of the sheet that has arrived at the transport roller with a delay contacts the transport roller, it is possible to align the leading edge positions of the two sheets of paper.

[0012]

However, in such a conventional recording apparatus, when a friction clutch is provided so that the leading ends of two sheets are always aligned and then the two sheets are pushed into the conveying roller, a friction clutch or the like is required. This mechanism is required, which may lead to an increase in the size of the device and an increase in cost.

On the other hand, in such a conventional recording apparatus, each of these recording sheets is ejected separately. Therefore, when different data is recorded on two recording sheets, the order of the pages is reduced. Had the problem of going crazy.

Therefore, the present invention has been made in view of such a situation, and it is possible to appropriately record data on recording sheets fed in parallel with a simple structure and to change the order of pages. It is an object of the present invention to provide a recording apparatus capable of storing recording sheets without going out of order.

As described above, detection signals from the sheet sensors S1A and S1B are input to the MPU 54, and when two recording sheets P1 and P2 are fed, for example, the recording sheet P1 Is the recording sheet P
If the recording sheet P1 is conveyed earlier than the recording sheet P2, the MPU 54 can recognize the leading end positions of the recording sheets P1 and P2 being fed based on the detection signals from the sheet sensors S1A and S1B.

When the recording sheet P1 is leading, the MPU 54 reads out the data of two recording sheets stored in the RAM 57 when the recording by the recording head 1 is started, and then, first, Is recorded on the preceding recording sheet P1, and the next data is recorded on the second recording sheet P2.

The two recording paper sheets P1 and P2 on which data are sequentially recorded in this manner are discharged to the stacking means 40 by the discharge rollers 20. At this time, since the preceding recording sheet P1 reaches the stacking means 40 first, the recording sheet P1 enters the tray 43 first along the inclined surfaces 41b and 42b of the left and right stackers 41 and 42 of the stacking means 40, and then enters the tray 43. The recording sheet P2 that was delayed
You will enter 3. Thus, the discharged recording sheet sheets P1 and P2 can be arranged in page order.

On the other hand, when the two recording sheets P1 and P2 are conveyed almost simultaneously, the MPU 54
The detection signals are input almost simultaneously from 1A and S1B. In this case, the MPU 54 determines that the recording sheet P1 on the right stacker side is the first recording sheet P1 and the first recording sheet P1.

As a result, the two recording sheets P1, P2
When the data is recorded almost simultaneously, the recording sheet P1 on the right stacker side, that is, the recording sheet P1 on which the data of the first sheet is recorded, is first placed on the tray 43 as described above.
And then another recording sheet P2 enters the tray 43. Thereby, the discharged recording sheets P1, P
2 can be arranged in page order.

Next, a recording operation and a paper discharging operation in the recording apparatus having the above-described configuration will be described with reference to a flowchart of FIG.

For example, when a recording command is received in a state where a plurality of recording sheets P1 and P2 having a small width are stacked on the stacking plate 24 of the automatic feeding device 23 as shown in FIG. The MPU 54 drives the feed motor M3 via the feed motor driver 62 to drive the feed roller 25 (S02). As a result, the uppermost recording sheets P1 and P2 of the plurality of stacked recording sheets are separated one by one on the left and right sides, and two sheets are fed in parallel in the direction C in the drawing.

Here, for example, when one recording sheet P1 is conveyed ahead of the other recording sheet P2, one of the two sheet sensors S1A and S1B (S1A in the figure) is the recording sheet. Detect the tip of P1 (O
N) (Y in S03), and in this case, since the two sheet sensors S1A and S1B do not detect (ON) the leading ends of the recording sheets P1 and P2 almost simultaneously (N in S11), the position is stored in the RAM 57 as T1. (S04).

Further, the feeding roller 25 is driven (S0
5) When the other sheet sensor S1B detects the leading end of the other recording sheet P2 (Y in S06), the position is stored in the RAM 57 as T2 (S07).

Then, after driving the feed roller 25 by a predetermined amount from the leading edge position T1 of the recording sheet P1 stored first,
The transport motor M2 is driven via the transport motor driver 61 to start driving the transport roller 14 (S08).

As a result, the preceding recording sheet P1 is conveyed from the stored position T1 to the recording position. After that, the MPU 54 moves the print head 1 in the scanning direction via the print head driver 59 so that the preceding print sheet P1
Starts recording for one line (S09). further,
After that, a new line is recorded for the next line.

After the line feed and the recording are repeated in this manner, when the second recording sheet P2 reaches the recording position from the stored T2 position, that is, the sheet sensors S1A, S1
When the second recording sheet P2 is conveyed by the difference that is the shift amount of the leading end positions of the recording sheets P1 and P2 detected by 1B, both the preceding recording sheet P1 and the second recording sheet P2 are conveyed. Recording of one line is started (S1
0).

By the way, if the recording is continued in this way, the recording on the preceding recording sheet P1 ends first. Then, when the recording on the preceding recording sheet P <b> 1 is completed, the MPU 54 drives the discharge roller 20. At this time, the recording on the two recording sheets P2 is continued.

As a result, the preceding recording sheet P1 is
After reaching the stacking means 40, the inclined surface 4 of the right stacker 42
It enters the tray 43 along 2b. Further, thereafter, the recording sheet P2 on which recording has been completed is placed on the inclined surface 4
It enters the tray 43 along 1b. Thus, the discharged recording sheets P1 and P2 are arranged in page order.

On the other hand, when the two recording sheets P1 and P2 are conveyed almost simultaneously and the two sheet sensors S1A and S1B detect (ON) the leading edge of the recording sheet almost simultaneously (Y in S11), the position is changed. It is stored as T1 (S12). After that, after driving the feed roller 25 by a predetermined amount, the drive of the transport roller 14 is started (S1).
3).

As a result, the recording sheets P1 and P2 are conveyed from the stored position T1 to the recording position. After this,
The MPU 54 moves the recording head 1 in the scanning direction via the recording head driver 59, starts recording the first sheet of data as the preceding recording sheet P1 with the recording sheet P1 on the right stacker side, and starts recording on the left stacker side. Record sheet P2
, The recording of the next one sheet of data is started (S1).
4).

After that, when the recording on these two recording sheets P1 and P2 is completed, the MPU 54
The paper discharge roller 20 is driven. Thus, the two recording sheets P1 and P2 reach the stacking unit 40 almost at the same time.

Thereafter, as shown in FIG. 6, the recording sheet P1 is first moved to the right stacker 42 by the difference in the inclination angle of the inclined surface.
Then, the recording sheet P2 enters the tray 43 along the inclined surface 41b of the left stacker 41. Thus, the discharged recording sheets P1 and P2 can be arranged in page order.

As described above, when recording by the recording head 1 is started, if the leading end positions of the recording sheets P1 and P2 are different, the first recording data is stored in the preceding recording sheet P1 and the next recording is performed. By recording the second data on the sheet P2, and when the leading end positions are almost the same, the predetermined recording sheet P1 is set as the preceding recording sheet P1.
By recording the second data on the other recording sheet P2, the data can be appropriately recorded on the recording sheets P1 and P2 fed in parallel with a simple structure.

When the positions of the tips are almost the same,
Data is recorded, and thereafter, a predetermined recording sheet P1 of the recording sheets P1 and P2 discharged almost simultaneously is first put into the tray 43 via the stacker 42 having the inclined surface 42b having a large inclination angle. , Each recording sheet P
1 and P2 can be stacked and stored in one place in order.

When data of a previous page is recorded on a preceding recording sheet or a predetermined recording sheet as in this embodiment, the discharged recording sheets are successively overlapped with the recording surface facing upward. Therefore, the order of pages is reversed from the order of recording. Therefore, by recording the data of the previous page on a recording sheet other than the delayed recording sheet or the predetermined recording sheet, it is possible to stack the recording sheets in ascending order of the pages in the discharged state. .

Next, a second embodiment of the present invention will be described.

In the first embodiment described above, the two recording sheets P1, P2 are formed by making the inclination angles of the inclined surfaces 41b, 42b of the right stacker 42 and the left stacker 41 different.
Although the stack timing of P2 is adjusted, in the present embodiment, the stacker of the stacking means 40 is supported so as to be tiltable in the directions D and E, for example, as shown in FIG. Each of 46 is configured to be tilted independently.

FIG. 9B shows a state in which only the right stacker 46 is rotated, and FIG. 9C shows a state in which only the left stacker 45 is tilted. With such a configuration, an arbitrary recording sheet can be put into the tray 43 first even if two sheets are discharged at the same time.

Here, instead of tilting only one of the right stackers 45 and 46 as in (b) and (c), one of the stackers may be tilted deeper than the other. An arbitrary recording sheet can be put in the tray 43 first.

In the case of a wide recording sheet,
The left and right stackers 45 and 46 may be stacked without rotating, or the left and right stackers 45 and 46 may be simultaneously rotated and loaded into the tray 43.

In each of the embodiments described above, the leading end positions of the two recording sheets P1 and P2 fed in parallel are determined by the two sheet sensors S attached to the inside of the recording apparatus.
1A and S1B, the present invention has been described. However, the present invention is not limited to this.
A reflection sensor or image reading means, which is a so-called scanner capable of reading image data, is attached to the carrier 2 on which the recording sheets P1 and P2 are moved while the carrier 2 is reciprocated a plurality of times during recording sheet feeding.
May be configured to detect the position of the tip.

In this case, since the positions of the recording sheets P1 and P2 in the width direction can be detected, not only the correction of the recording position in the recording sheet conveyance direction but also the correction of the recording position in the width direction enables more accurate recording. It becomes possible.

[0079]

As described above, according to the present invention, when recording data, if the leading end positions of the recording sheets are different, the recording of the first data on the preceding recording sheet is performed. By starting the recording of the second and subsequent data sequentially on the next recording sheet, and when the leading end positions are almost the same, a predetermined recording sheet is regarded as the preceding recording sheet and the first data is recorded. The recording of the second and subsequent data is sequentially started on the other recording sheets, so that the data can be appropriately recorded on the recording sheets fed in parallel with a simple structure. it can.

Further, by configuring the stacking means for storing the recording sheets so that the recording sheets on which data is recorded first are stacked and stored first, the recording sheets can be stored in one place without disturbing the order. Can be stored.
