[0005]

However, Japanese Patent Application Laid-Open No. Hei 8-3
In the image recording apparatus described in JP-A-14022, a plurality of photographic papers are sent out by the first transport roller pair "26" which is a single transport means, so that the arrival position of the leading end cannot be adjusted for each photographic paper. However, the leading edge of the photographic paper cannot be accurately aligned.

If the leading edge of the recording material is not exactly aligned as described above, the leading edge of the recording material may be skewed in the subsequent nip transport system, or the leading edge of the recording material may be shifted in the recording area. An image recording unit that records an image on the premise that the images are correctly aligned may record a shifted image on one of the recording materials.

An object of the present invention is to convey a plurality of recording materials with their leading positions more accurately aligned and arranged in the width direction.

Further, in the prior art, it is described that a plurality of recording materials are conveyed side by side in a width direction by a nip roller pair which is a single conveying means, but a plurality of recording materials are conveyed by a single conveying means. No description is given for the case where only one of them is conveyed. However, when only one of a plurality of recording materials is conveyed by a single nip roller pair, which is a single conveyance unit, the nip roller pair is originally designed to convey a plurality of recording materials arranged in the width direction. It was found that the lack of one of them causes the nip to be out of balance, causing the recording material to skew.

[0009] Therefore, it has been studied to make the material of the driven roller of the nip roller pair soft so that the nip pressure becomes constant regardless of the presence or absence of one recording material. It was sticky and not practical.

[0010] The object of the invention described in claims 12 to 18 is:
Even when only one of the plurality of recording materials is conveyed by the nip roller pair, the skew of the recording material is suppressed regardless of the material of the nip roller pair.

Further, in the prior art, it is described that a plurality of recording materials are conveyed side by side in a width direction by a single nip roller pair as a single conveying means, but one of the plurality of recording materials is thicker than the other. The case is not described. However, when a plurality of recording materials, one of which is thicker than the other, are conveyed by a single nip roller pair, which is a single conveying unit, the nip roller pair conveys a plurality of recording materials having an essentially equal thickness in the width direction. Because of the design, it was found that the driving force for the thicker recording material was greater than the driving force for the thinner recording material, causing skew.

Further, the conventional method of adjusting the nip roller pair when the thickness of the recording material is changed is to adjust the stroke of the entire nip roller pair or to adjust the distance between the two rollers of the nip roller pair. is there. Accordingly, it has been found that when the thickness of the thicker recording material is adjusted by the conventional method, the driving force for the thinner recording material becomes insufficient, and there is a problem that the conveyance becomes poor. In addition, it was found that when the thickness was adjusted to the thickness of the thinner recording material, the pressure applied to the thicker recording material was excessive, which had a bad influence on the recording material.

The objects of the invention described in claims 15 and 18 are as follows.
Even when a plurality of recording materials having different thicknesses are conveyed side by side in the width direction, each recording material is conveyed favorably, and skew, conveyance failure, and adverse effects on the recording material are suppressed.

The cutting section 4 cuts the plurality of sent photosensitive materials P1 and P2 at a predetermined cutting position between the holding position of the first delivery roller pair and the holding position of the second delivery roller pair.
The cutting section 4 has a movable blade 41 and a fixed blade 42 having a length in the width direction covering the entire area in the width direction of the plurality of photosensitive materials P1 and P2.

The transport section 6 has a first to a fifth transport roller pair from the sending section 3 side, and each transport roller pair can sandwich and transport the photosensitive materials P1 and P2 in the width direction. A single transport drive roller 61-65 in the width direction and a single transport driven roller 66-70 in the width direction.

The exposure section 7 has an exposure head 71 for blue light, an exposure head 72 for green light, and an exposure head 73 for red light. Then, the blue light exposure head 71 is positioned between the nipping position of the second pair of transport rollers of the transport section 6 including the transport drive roller 62 and the transport driven roller 67, and the transport drive roller 63.
A predetermined position between the nipping position of the third transport roller pair of the transport unit 6 including the transport driven rollers 68 is defined as an exposure area.

Then, the transport section 6 can move the transport driven roller 66 of the first transport roller pair up and down, whereby the one of the transport section 6 composed of the transport drive roller 61 and the transport driven roller 66 can be moved. The second transport roller pair can be in a state in which the photosensitive materials P1 and P2 can be sandwiched and transported, and in a separated state.

When a plurality of photosensitive materials P1 and P2 are conveyed to an exposure area side by side in the width direction, as shown below,
The main part 1 operates.

First, in a state where the first pair of conveying rollers of the conveying section 6 is separated, the sending section 3 operates the plurality of magazines 11, 1, and 2.
The photosensitive materials P1 and P2 are sent out from the rolls accommodated in the printer 2 in the width direction. When the detection sensor 51 detects that the photosensitive material P1 sent by the sending unit 3 has reached the detection position, the magazine driving unit that drives the magazine 11 of the sending unit 3, the first sending drive roller 31, and the second sending drive By stopping the drive roller 33, the feeding of the photosensitive material P1 is stopped. When the detection sensor 52 detects that the photosensitive material P2 sent by the sending unit 3 has reached the detection position, a magazine driving unit that drives the magazine 12 of the sending unit 3, the first sending drive roller 36, and the second sending drive By stopping the drive roller 38, the feeding of the photosensitive material P2 is stopped.

When the feeding of the photosensitive materials P1 and P2 is stopped, the leading positions of the plurality of photosensitive materials P1 and P2 are more accurately aligned.

Then, the transport section 6 is driven by a transport driven roller 66.
Is moved downward, and the first transport roller pair of the transport section 6 including the transport drive roller 61 and the transport driven roller 66 sandwiches the photosensitive materials P1 and P2. Thereafter, the cutting section 4 cuts the plurality of photosensitive materials P1 and P2. Thereafter, the second delivery driven rollers 34 and 39 of the delivery section 3 are moved upward, and the second delivery roller pair is separated.
After that, the conveying roller pair of the conveying unit 6 moves the plurality of photosensitive materials P
1. P2 is pinched and transported.

Thus, from the state where the leading positions of the plurality of photosensitive materials P1 and P2 are more accurately aligned, the single transport drive rollers 61 to 65 and the transport driven rollers 66 are arranged in the width direction.
According to -70, the plurality of photosensitive materials P1 and P2 are conveyed side by side without tension from the feeding unit 3 and the magazines 11 and 12 in which separate rollers are provided for the plurality of photosensitive materials P1 and P2. It is easier to transport the photosensitive materials P1 and P2 while maintaining the leading positions thereof more accurately aligned.

Accordingly, not only in the transport section 6 but also in the nip transport system of the subsequent development processing section 8, it is possible to prevent the photosensitive material that has advanced further from skewing.

Further, the image control unit 2 controls a plurality of photosensitive materials P
1. Exposure image data is generated from output image data of output images recorded on P1 and P2 on the assumption that the tips of a plurality of photosensitive materials P1 and P2 are accurately aligned in an exposure area. The exposure unit 7 exposes a plurality of photosensitive materials P1 and P2 to record a latent image based on the exposure image data.

Therefore, when the photosensitive material is skewed, a misaligned image is recorded. However, since the photosensitive material can be prevented from being skewed, a good latent image can be recorded on both of the plurality of photosensitive materials P1 and P2. Can be.

Further, since the detection positions of the detection sensors 51 and 52 are located between the nipping position of the first conveying roller pair of the conveying unit 6 and the nipping position of the second conveying roller pair, The head positions of the plurality of photosensitive materials P1 and P2 can be more accurately aligned by a simple configuration and control in which the second transport roller pair can take a state in which the photosensitive material can be sandwiched and transported and a state in which the photosensitive material P1 and P2 can be separated. It can be transported while maintaining the state.

As a modification of the present embodiment, the sending section 3 may not have the sending roller pair on the exposure area side from the cutting position. That is, the second delivery drive roller 3
The third and third delivery driven rollers 34 and 39 may be omitted. In this case, since the tension of the photosensitive material tends to be insufficient at the time of cutting, the first pair of transport rollers of the transport section 6 may be brought closer to the sending section 3. This also makes it easier to transport the photosensitive materials P1 and P2 side by side in the width direction while stably maintaining a state where the leading positions of the photosensitive materials P1 and P2 are more accurately aligned.

Embodiment 2 This embodiment is a modification of Embodiment 1. Hereinafter, all differences from the first embodiment will be described with reference to FIG. 3 which is a schematic perspective view of a main part of the image recording apparatus of the second embodiment.

The sending section 3 includes second sending driven rollers 34, 3
9 can be moved up and down, so that both of the second delivery roller pairs of the delivery unit 3 can be in a state where the photosensitive material can be nipped and conveyed and a state where the photosensitive material can be separated.

When the sending section 3 sends the photosensitive materials P1 and P2 from the magazines 11 and 12 to the transport section 6, the following operation is performed. First, in a state where the second delivery roller pair is separated, the first delivery roller pair sends out the photosensitive materials P1 and P2,
The first delivery roller pair of the delivery unit 3 is a photosensitive material P having a predetermined length.
After sending out the first and second P2, the second sending roller pair moves the photosensitive material P

The first transport roller pair of the transport section 6 comprising the transport drive roller 61 and the transport driven roller 66 is
This can be a state where the photosensitive material is closed and a state where the photosensitive material is conveyed. The separated state may not be taken.

When a plurality of photosensitive materials P1 and P2 are conveyed to the exposure area side by side in the width direction, the sending section 3 is moved to the cutting section 4 while the first conveying roller pair of the conveying section 6 is closed.
The distance from the cutting position to the nipping position of the first conveying roller pair of the conveying unit 6 is set to a time necessary for advancing the tips of the plurality of photosensitive materials P1 and P2, and the unevenness of the sending speed of the sending unit 3 is considered. The time obtained by adding the extra time, a plurality of photosensitive materials P1,
The tip of P2 is sent out. As a result, both ends of the plurality of photosensitive materials P1 and P2 abut against the first transport roller pair of the transport unit 6. That is, a plurality of photosensitive materials P1, P
The leading position of No. 2 is more accurately aligned with the first pair of conveying rollers of the conveying unit 6.

Then, with the tips of the plurality of photosensitive materials P1 and P2 abutting against the first pair of conveying rollers of the conveying section 6, the first pair of conveying rollers of the conveying section 6
1 and P2 are conveyed, and the conveying roller pair of the conveying unit 6 conveys the photosensitive materials P1 and P2 while nipping them. The transport roller pair of the transport unit 6 includes a single transport drive roller 61 to 65 and a transport driven roller 66 to 66 in the width direction.
70, the plurality of photosensitive materials P1 and P2 are conveyed side by side in the width direction while maintaining a more accurate alignment of the leading positions.

Accordingly, not only in the transport section 6 but also in the nip transport system of the subsequent development processing section 8, it is possible to prevent the photosensitive material that has advanced further from skewing.

Further, the image control unit 2 controls a plurality of photosensitive materials P
1. Exposure image data is generated from output image data of output images recorded on P1 and P2 on the assumption that the tips of a plurality of photosensitive materials P1 and P2 are accurately aligned in an exposure area. The exposure unit 7 exposes a plurality of photosensitive materials P1 and P2 to record a latent image based on the exposure image data.

Therefore, when the photosensitive material is skewed, a misaligned image is recorded. However, since the photosensitive material can be prevented from being skewed, it is necessary to record a good latent image on both of the plurality of photosensitive materials P1 and P2. Can be.

When both rear ends of the plurality of photosensitive materials P1 and P2 have passed through the nipping position of the first transport roller pair of the transport section 6 including the transport drive roller 61 and the transport driven roller 66, the transport is completed. The first conveying roller pair of the unit 6 returns to the closed state, the second driven rollers 34 and 39 move upward, the second sending roller pair is separated, and the next photosensitive material is sent. .

In the image recording apparatus of the present embodiment, the detection results of the detection sensors 51 and 52 are not used as in the first embodiment, so that the detection sensors 51 and 52 need not be provided.

As a modification of the present embodiment, the cutting section 4 is provided with a fixed blade and a movable blade for each of the rolls accommodated in the plurality of magazines 11 and 12, so that the photosensitive material is independent of each other. P1 and P2 may be cut.
Thus, by shifting the timing of cutting the photosensitive material P1 and the photosensitive material P2, it is easy to make the lengths of the plurality of photosensitive materials P1 and P2 conveyed side by side in the width direction different.

This is because the distance L from the nipping position of the pair of feeding rollers of the feeding section to the nipping position of the transport driving roller 62 and the transport driven roller 67 of the transport section 6, the standard feeding speed V of the feeding section 5, The time T1 when the detection sensor 51 detects that the photosensitive material P1 has reached the detection position, and the time T when the detection sensor 52 detects that the photosensitive material P2 has reached the detection position.
2, the target time T3 (T3>) at which the leading ends of the photosensitive materials P1 and P2 are aligned with the nipping positions of the transport drive roller 62 and the transport driven roller 67 of the transport unit 6 and the photosensitive materials P1 and P2 are arranged in the width direction and fed. T1, T2), the feed speed V1 of the feed roller pair including the feed drive roller 53 and the feed driven roller 54, and the feed drive roller 53 and the feed driven roller 5
The feed speed V2 of the feed roller pair consisting of No. 4 is obtained by the following equation. However, the larger the numerical value of the time is, the later the time is, and max (A, B) is a function for selecting the larger numerical value between A and B.

T3 = max (T1, T2) + L / V V1 = L / (T3-T1) V2 = L / (T3-T2) Thus, the transport driving roller 62 and the transport driven roller 67 of the transport unit 6 are pinched. The photosensitive materials P1 and P2 are fed in a state where the heads of the photosensitive materials P1 and P2 are aligned at the positions and the photosensitive materials P1 and P2 are arranged in the width direction. Then, the pair of conveying rollers of the conveying unit 6 is a photosensitive material P

1. Exposure image data is generated from output image data of output images recorded on P1 and P2 on the assumption that the tips of a plurality of photosensitive materials P1 and P2 are accurately aligned in an exposure area. The exposure unit 7 exposes a plurality of photosensitive materials P1 and P2 to record a latent image based on the exposure image data.

Accordingly, when the photosensitive material is skewed, a misaligned image is recorded. However, since the photosensitive material can be prevented from being skewed, it is necessary to record a good latent image on both of the plurality of photosensitive materials P1 and P2. Can be.

Hereinafter, all the differences from the first embodiment will be described.

In the image recording apparatus of the first embodiment, the transport unit 6
In the state where the first conveying roller pair is separated, the sending unit 3
Sends the photosensitive materials P1 and P2 from the rolls accommodated in the plurality of magazines 11 and 12, respectively, side by side in the width direction, and the detection sensor 51 detects that the photosensitive material P1 sent by the sending unit 3 reaches the detection position. Is detected, the magazine driving unit that drives the magazine 11 of the sending unit 3, the first sending driving roller 31, and the second sending driving roller 33 are stopped, and the detection sensor 52 detects that the photosensitive material P2 sent by the sending unit 3 When it is detected that the detection position has been reached, the magazine 12
The first drive roller pair of the transfer unit 6 stops after stopping the magazine drive unit, the first delivery drive roller 36, and the second delivery drive roller 38 that drive the photosensitive material P.
In the present embodiment, the image recording unit causes the recording member to output an image for recording on each of the photosensitive materials P1 and P2 in accordance with the detection results of the detection sensors 51 and 52. The difference is that the exposure image data is created so that the recording timing based on the image data is shifted.

For example, the time T1 at which the detection sensor 51 detects that the photosensitive material P1 sent by the sending unit 3 has reached the detection position, and the detection sensor 52 determines that the photosensitive material P2 sent by the sending unit 3 is at the detection position. In the case where the time T2 when the arrival of the photosensitive material P1 is detected is the same as that of the photosensitive material P1 as shown in FIG.
The exposure image data in which the leading end position of the output image data to be recorded on the photosensitive material P2 and the leading end position of the output image data to be recorded on the photosensitive material P2 are the same.

On the other hand, the time T1 at which the detection sensor 51 detects that the photosensitive material P1 sent from the sending section 3 has reached the detection position is the time T1 at which the detection sensor 52 detects the photosensitive material P2 sent from the sending section 3. If it is later than the time T2 when it is detected that has reached the detection position, as shown in FIG.
The leading end position of the output image data to be recorded on the photosensitive material P1 is the exposure image data after the leading end position of the output image data to be recorded on the photosensitive material P2 by an amount corresponding to the time difference (T1-T2). create.

Thus, a plurality of photosensitive materials P1, P2
However, even if the head position passes through the first conveying roller pair of the conveying unit 6 at a position different in the conveying direction, the “conveying roller pair including a single conveying driving roller in the width direction” of the conveying unit 6
Transports a plurality of photosensitive materials P1 and P2 while sandwiching them.
Since the plurality of photosensitive materials P1 and P2 can be transported while maintaining the relationship of the leading position in the transport direction, each of the photosensitive materials P1 and P2 is placed at a predetermined detection position in the transport direction before the first transport roller pair of the transport unit 6. Exposure unit 7 exposes a plurality of photosensitive materials P1 and P2 based on exposure image data created according to the detection results of detection sensors 51 and 52 that detect whether photosensitive materials P1 and P2 have arrived. With each photosensitive material P
The recording timing is adjusted based on the output image data to be recorded on the photosensitive materials P1 and P2.
The deviation of the output image recorded on P2 can be reduced.

In addition, driven rollers 91 and 92 are provided. Accordingly, since the driven rollers are provided for each of the plurality of photosensitive materials P1 and P2 for each of the transport driving rollers of the transport unit 6, the plurality of photosensitive materials P1 and P2 are arranged side by side in the width direction and exposed. When transporting the photosensitive material P

This prevents the pressure of the first and second rollers 92 from being pressed against the transport drive roller 80 in an inclined state or uneven pressure.

Thus, a plurality of driven rollers provided for each transport driving roller are simultaneously pressed against the transport driving roller, so that a plurality of driven rollers provided for the transport driving roller form one wide-width roller. Even if the photosensitive material described above can be conveyed to the exposure area, the skew of one wide photosensitive material conveyed can be satisfactorily suppressed.

Further, a pressure-contact separation drive source 96 is provided for each transport roller pair, and the driven roller is independently pressed from the transport drive roller and separated from each other for each transport roller pair. be able to.
