を行なう画像記録装置に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an image recording apparatus capable of recording multicolor images, and more particularly to an image recording apparatus that has a plurality of recording sections and performs back-and-forth scanning recording.
記録速度の向上は記録装置に関し常に追求され

いう問題がある。 Improving recording speed is a constant pursuit regarding recording devices. Regarding this improvement in recording speed,
In the case of a recording method that records a multicolor image, etc., it is conceivable to perform the recording operation not only when the recording head moves forward, but also when it moves backward. However, in the case of the above-mentioned recording method, it would be difficult to record only yellow, magenta, cyan, and black (hereinafter referred to as Y, M, C, and BK) during forward motion if the recording was simply performed during backward motion in the same way as during forward motion. While recording is performed in the order of BK, C, M, and Y during the backward movement, the recorded color that should be the same is different between the forward movement and the backward movement. There is a problem with different color tones.

BK2 faces the left end of the recording paper 1, that is, the column address C1, as shown by the two-dot chain line and solid line in FIGS. 4A and 4B. Preset the line address pointer 33 to 1. Column addresses 1, 1601, 1521, and 1441 are preset to each column address pointer 32Y, 32M, 32C, and 32BK in accordance with the spacing of each head.Here, the spacing of each head is 80 dots (10 mm). Each recording head driver 34Y, 3
A switching signal 38 is supplied to 4M, 34C and 34BK, and the output signals of these drivers are supplied to upper recording heads 13Y1, 13M1, 13C1 and 13BK1. Also, 3 of them are included in the head driver.
A prohibition signal 39 is supplied to 4M, 34C, and 34BK to stop their operations. This is because each of the recording heads 13M1, 13C1, and 13BK has not yet faced the surface of the recording paper 1.

When the read signal 40 is supplied to M, 31C and 31BK, each page memory 31Y, 31M, 31
C and 31BK each address l01C001,
Dot data is read from each of l01C1601, l01C1521, and l01C1441, but since the operation of all the printers except the head driver 34Y is stopped, only the recording head 13Y is driven, and yellow dots corresponding to the dot data are recorded on the recording paper 1. Ru.
Next, column address pointers 33Y, 33M,
33C and 33BK in the forward direction, and supplies a drive signal to the carriage drive motor driver 35 to drive the carriage movement pulse motor 8.
is rotated by one pulse to move the carriage 11 in the direction of arrow R by one pitch, that is, 1/8 mm. Here again, each page memory 31Y, 31M,
A read signal 40 is supplied to 31C and 31BK, and the recording head 13Y is driven to read the page memory 3.
A yellow dot corresponding to the dot data at address l01C002 of 1Y is recorded on the recording paper 1. While repeating these operations, move the carriage 11 in the direction of arrow R.
Move 80 dots (10mm) in the direction.

From this point on, the inhibition of the operation of the recording head driver 34M is canceled and the recording operation continues in the direction of arrow R. As a result, the recording head 13M scans the area previously scanned by the recording head 13Y, and magenta dots are recorded in accordance with the dot data supplied from the page memory 31M.

When the dot advances, the recording head driver 34
The carriage 11 is caused to scan in the direction of arrow R while canceling the prohibition of BK movement.

Each head driver 34Y, 34M, 34C and 34 is connected again in the order of 13M, 13C and 13BK.
A prohibition signal 39 is supplied to BK to stop its operation.

When BK1 faces column address C1680, position sensor 17R generates a detection signal. Therefore, the carriage 11 is moved and each page memory 3 is moved.
Stop reading 1Y, 31M, 31C and 31BK. At this point, the line address of recording paper 1
In the l1 part, there are 4

BK２とする。 Next, the carriage 11 is moved in the direction of arrow L to perform a similar recording operation, but in this case, a ring counter is used for each column address pointer 32Y, 32M, 32C, and 32BK as described above. The respective column addresses at the end of the recording operation in the direction of arrow R are 241, 161, and 81.
and 1. Therefore, when recording in the direction of arrow L, each column address pointer 32Y, 32M, 32C, and 32BK can be simply moved in the opposite direction. Also, the line address pointer 33 is incremented in the forward direction to 02,
The output signals of the recording head drivers 34Y, 34M, 34C and 34BK are supplied to the lower recording heads 13Y2, 13M2, 13C2 and 13.
Let's call it BK2.

If the recording operation is performed up to line address l20 while switching the supply destination of the output signals of 4M, 34C, and 34BK, and disabling some operations at the start and end of travel, each page memory will be stored on the recording paper 1. A color image can be recorded by combining data of each color stored in 31Y, 31M, 31C and 31BK.

In addition, as a result of enabling reciprocating recording, there is no need for the carriage to go back at high speed as in the conventional method, the configuration of the carriage movement motor driver is simplified, and the housing that is generated when the carriage goes back at high speed is eliminated. Body recoil also disappears.

装置構成の簡素化を図ることができる。 As described above, according to the present invention, by making the order of coloring constant during forward movement and backward movement of a multicolor recording device that performs reciprocating scanning recording, image quality can be improved, and the same color By having a common supply means for supplying the recording agent to the recording section,
The device configuration can be simplified.

Therefore, the configuration of the supply means can be downsized, and clogging of the recording agent can be prevented.
