Abstract

PURPOSE:To obtain high sub-scanning accuracy and to make the title apparatus compact by taking out a recording sheet from a receiving case to feed the same in the reverse direction and transferring the recording sheet through a second feed passage and performing the sub-scanning of said sheet to record an image. CONSTITUTION:When the leading end part of the sheet fed along a first feed passage passes between sub-scanning rollers 2 and the rear end part of the sheet issues from a supply magazine 3 perfectly to reach a vertical direction, the rotation of the sub- scanning roller 2 and main rollers 7, 12 is stopped. The sub-scanning roller 2 is rotated in the reverse direction and the sheet advances in the reverse direction along a second feed passage. When the leading end of the sheet is detached from the sub-scanning roller 2, the sheet falls and the rear end of the sheet impinges against the sheet correcting part 22a provided to the lowermost part of a guide plate 22 to be aligned. A main roller 12 is rotated in a counterclockwise direction and the sheet is fed in a recording position direction along the second feed passage. When the sub-scanning of the sheet is started by the sub-scanning roller 2, the shutter in a laser optical system is opened to start main scanning by laser beam and a latent image is recorded on the emulsion surface on the upper surface of the sheet.

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an image recording apparatus that forms an image by scanning a recording sheet 1 with a light beam.

[Prior Art] No. 10 is a conventional example of a sheet conveying device in a recording apparatus that optically records images on recording sheets 1-7, and in the figure, 132 is a stack of unused recording sheets. It is stored in the supply magazine 131. A suction cup 134 connected to an air lifter 133 is provided at the end 6HjH of the sea 1-132. Air no lifter 133, l

When the liquid comes into contact with the liquid, the slave current is activated. When the sea l-132 is sandwiched between this tram 142 and the front lug O-ra 143, it is immediately conveyed in the middle direction by the rotational force of the sub-hill j-ram 142.

The optical system JL-144 is placed in the L direction of the holding plate 137, and the laser beam emitted from the laser light source 145 passes through the mirror 146 (between the two nip-low parts 143). Light 0] Right, sub-scan l/ram 142
The photosensitive recording sheets 1-132 and -J-2, which are conveyed by J, are main-scanned to form a predetermined image.

The sheet 1-132 on which the image has been formed in this way is manually fed out from between the sub-running blue tram 143 and the nip roller 143 at the rear stage in the figure, and is loaded with its own weight 'C weight 21-' sequentially from the tip and into the receive magazine 47. It is stored.

[Is it an invention?] 4 Problems to be decided] However, in the conventional device described above, there is a problem that the device becomes large due to its structure.Also, the holding plate 1
37 is a medium-length sheet that is slightly longer than sheet +32, so it is stacked from the recording device ♂t, and after the unrecorded sheet j, t.
ji mate's 1 width MI L. Theoretically, the total length of the sheet is 1, f. > 2L, and it is generally a beam. −
3L, culm order.

In the conventional configuration, in order to further shorten Lo'd, the retaining plate 1
It is necessary to shorten the total length of 37. In this case, there is a strong possibility that the trailing end of the sheet 132 will accumulate in the supply magazine 131 when recording starts and come into contact with the upper surface of the stack of unrecorded sheets. As a result, the resistance force acting in the direction opposite to the sheet conveyance direction described above increases further than in the conventional example, and furthermore, it is thought that the change in resistance force becomes more severe. This is because the surface of the unrecorded sheet has a higher coefficient of friction than the holding plate 137 whose surface has been smoothed, and the conditions are worse in terms of static electricity and dullness. Therefore, unevenness in the sheet conveying speed, that is, the sub-scanning speed increases, leading to image deterioration. Therefore, the conventional device has problems. <21. , , it was difficult to do so.

The purpose of the present invention is to make the device more compact without deteriorating the transport stability.

[F-stage for solving the problem] The present invention which solves the above problem 4- includes a storage case that stores the recording sheet 1, and a storage case that takes out one recording sheet 1- from the storage case and feeds it to the recording position. In an image recording apparatus, the image recording apparatus has a recording stage f which records the first stage 1 in the main 5L scanning direction at the [ji+ recording position], and a recording stage f which records the first stage 1 in the main 5L scan direction from the storage case to the a first conveyance path that moves along the route;
Roughly remove the storage case, move it along the δ, Y path, and then select the second transport path that has less transport resistance than the first transport path. The trailing edge of the recording sheet taken out from the storage case along the first conveyance path is marked t, Y of both the first and second conveyance paths.
On the road: 1tbk, etc., first turn the control means to transport the recording sheet in the opposite direction and transfer it to the second transport path, and then transfer the C recording sheet to the second transport path using the second transport path. Let's make an apricot-(,
1) This is an image recording apparatus characterized in that an image is recorded on a 'C recording sheet at the recording position described in 1].

[Proportionality] Hereinafter, an embodiment in which the present invention is applied to an image recording apparatus that records a C image by scanning a photosensitive sheet film with a light beam will be described in detail.

FIG. 1 is a block diagram of an embodiment of the present invention. In the figure, reference numeral 1 indicates a laser optical unit, which includes a laser light source, a modulator, a polygon mirror, a mirror, etc., and which responds to a 1σ]I image signal. The beam 1a is deflected in the main scanning direction using the rotation of a polygon mirror, and the film surface at the recording position is optically scanned. Note that while the sheet is being fed, a shutter (not shown) or the like is used to prevent the laser beam from irradiating the recording position. A sub-scanning roller 2 is disposed below the optical system 1, and the sub-scanning roller 2 has a pair of rollers (one of which has a rotational driving force and is driven by another force, and there is a roller between the two rollers). The held sheet is conveyed at a constant speed to perform sub-scanning for image recording.The laser beam 1a from the laser optical system 1 is optically scanned near the scanning 60-ra 2. Below the scanning roller 2, a sub-life cashin 3 for stacking and storing unrecorded sheets on the vessel from below, and a receive magazine 4 for storing recorded sheets are arranged in parallel. In 3.4, a slide I/lid 3a, 4a which can be opened and closed with six openings for putting in and taking out sheets is provided in each gun.
13. With the slide lids 3a and 4a closed, the interior of the magazine is shielded from light from the outside. It should be noted that the film emulsion surfaces of the sheets laminated inside both magazines 3.4 both face the -F side, 71 to further enhance the light shielding effect.

Reference numeral 5 denotes a suction cup, which is provided for taking out the seals stored in the magazine 3 one by one from the ``old'' section of the magazine 1. Reference numeral 6 denotes a direction changing unit 1-, which controls the traveling direction of the transported sea.

FIG. 2 shows a detailed plan view of this direction changing unit 6. The main roller 7 has a chain 28, a sprocket 27.
The drive V of the motor 26 transmitted by the motor 29 allows rotation in both directions. 4i117 a is motor 30
, driven by gears 31, 32 and controlling the operation of a lever fixed at Ci'+h7a-t=, independent of the rotation of the main roller. The planetary roller 8 is rotatably supported by a shaft 8a, and the shaft 8a is supported by a spring 1o along an elongated hole provided in a lever 9. Note that the surface of the planetary roller 8 is smooth. If it is processed and the frictional resistance is small, it is not necessarily rotatable and -C is also good.

The planetary roller 8 revolves around the main roller in a floating manner according to the rotation of the lever 9, and the main roller 7 is rotated by C 210.
When the lever 9 rotates and the planetary roller 8 moves from position a to position C, the axis of the planetary roller 8 is guided by the guide bin shown in the figure below jfs, and the planetary roller 8 is moved to the main roller. 7)
I'm leaning on it. Incidentally, an encoder (not shown) is connected to the shaft 7a, and the planetary rotation angle of the planetary roller 8 can be detected from the output of the encoder.

Returning to FIG. 1, reference numeral 11 is a direction change unit having the same configuration as the direction change unit 6, and the main roller 12 is driven by one motor 26 via the main roller.

Reference numerals 6, 17, and 18 are rotatably supported fixed rollers that guide the film so that it does not rub against the surface of the film or against the guide plate during conveyance. 19no! Since JI22 uses a guide plate or a conveyance path with a 1-111 width and a gentle curvature to guide the sheet, the film surface will not be damaged by the guide plate during conveyance and the emulsion surface of the film surface will not be damaged. It is considered as such. At the bottom of the guide plate 22, there is a seat ry for tilt correction T and positioning of the sheet.
A stop portion 22a is provided.

The length of the conveyance path from the sheet 1□E l section 22a to the sub-scanning roller 2 is set to be longer than the length of the sheet in the conveyance direction, and the length of the conveyance path from the sub-scanning roller 2 to the end of the guide plate 19 is set to be longer than the length of the sheet in the conveyance direction. The length of the conveyance path is set to be slightly shorter than the length of the sheet in the conveyance direction.

Furthermore, when the leading end of the sheet taken out from the supply magazine 3 reaches the sub-scanning roller 2, the rear end of the sheet also rests inside the supply magazine and contacts the laminated sheet. Hereinafter, the route along which the sheet taken out from the supply magazine 3 is conveyed through the Guy Mill plate 191 will be determined as follows.
The path from the lower end of the guide plate 22 to the plate 19 will be referred to as the second conveyance path. The first conveyance path and the second conveyance path share a path from the initial position of the planetary roller 8 shown in FIG. 1A to the guide plate 19.

The second conveyance path is provided so as to roughly surround the outer peripheries of both the supply magazine 3 and the one-nosieve magazine 4. This makes the entire device compact.

Next, the operation of this image recording apparatus will be explained using FIGS. 3 to 8.

Supply magazine 3 that is stacked to store unrecorded sheets
is loaded into a predetermined position within the main body of the device, and the slide lid is opened from inside the device, which is shielded from light.

Next, operate the suction cup 5 and hold the top one of the sheets stacked in the supply magazine 3 as shown in Fig. 3. Next, by rotating the lever 9 about 90 degrees around the clock and rotating the planetary roller 8 from the initial position Wa to the position b, the seat is lifted by the suction cup 5.
is held between the main roller 7 and the planetary roller 8. When the leading edge of the uppermost sheet is held in this way, the main roller 7 is rotated counterclockwise, and at the same time the lever 9 is rotated at the same angular velocity, the main roller 7 and the planetary roller 8 are While holding the parts, rotate at the same time and change the direction of movement of C and C to upward direction. When the JV star roller 8 returns to the initial position a, stop the rotation of the C lever 9 and continue to adjust only the main roller 7. SL (directly upward direction).

The leading edge of the sheet reaches the direction changing unit 11, and is held between the main roller 12, which rotates counterclockwise in the J direction at the same speed as the main roller 7, and the planetary straw 13, which is waiting at position d, and then the lever 14 also rotates rIi1 at the same angular speed as the main roller 12 to change the traveling direction of the sheet. When the planetary roller 13 h) e reaches the 4D position, the lever 14 stops, the direction of movement of the tip of the sheet is fixed to the left, and the main roller 12 [! By continuing the q rotation, the sheet advances to the left along the conveyance path as shown in FIG.

The leading edge of the sheet conveyed along the first conveying path passes between the roller blades of the rotating sub-scanning roller 2, the trailing edge of the sheet completely comes out of the supply magazine 3, and the trailing edge of the sheet When the sheet reaches the position shown in FIG. 5 where the sheet is oriented vertically on the conveyance path, the sub-scanning roller 2 and the main roller 7.12 of the previous direction changing unit stop rotating.
Next, the planetary rollers 8.13 are retracted to positions c and f, respectively, indicated by dotted lines, and release the sheets that have been clamped. That is, only the driving force of the sub-scanning roller 2 is transmitted to the sheet.

Here, the sub-scanning roller 2 starts rotating in the opposite direction, and the sheet advances in the opposite direction along the second conveyance path. At this time,
The rear end of the sheet descends vertically and enters the second conveyance path guided by the guide plate 22. When the leading edge of the sheet comes off the counter-rotating sub-scanning roller 2, the sheet falls under its own weight, and the sheet 1 to the trailing edge abut against the sheet straightening section 22a at the bottom of the guide plate 22, and the sheets and trailing edges are aligned. Even if the sheet taken out from the Zaburi magazine or the sheet is tilted by °C with respect to the direction of the conveying force due to the transportation of Cocoa-C + Ia-CM, can the tilt be corrected by cocooning? The position of the sheet can be perfectly aligned.

Once the positioning has been performed in this way, the main roller 2 is rotated in the counterclockwise direction, the planetary roller 13 is returned to the device (e), and the positioned sheet is conveyed along the second conveyance path in the direction of the recording position. do. The tip of the sheet reaches the sub-scanning roller 2, which rotates in the forward direction in the sub-scanning direction, and the tip reaches the
When the spindle 1 is held between the pair of rollers, the planetary rollers 13b) and 13f are simultaneously retracted to the contact position and the main roller 12 is stopped.

When the sub-scanning roller 2 starts sub-scanning the sheet, the shutter etc. in the laser optical system 1 are opened.
Main scanning is started on the C sheet 1- by the laser beam, and a latent image is recorded on the emulsion surface on the upper surface of the sheet as shown in FIG.

The sheet that is sub-scanned along the second conveyance path is curved along the outer periphery of the main roller 12, or the curvature in this part is due to the repulsive force of the bending of the flexible sheet), sorting, or its own weight. The curvature is close to the natural state in which the hanging forces of the sheet cancel each other out, and the force applied from the sheet to the planetary roller 13 and the guide plate 21 is small. Furthermore, in other parts of the second conveyance path, the sheet is not curved and maintains a natural state, so there is little friction between the sheet and the rollers or kite board. Comparing this second conveyance path with the first conveyance path through which the sheet taken out from the supply magazine 3 is conveyed, it is found that the trailing edge of the sheet conveyed like the first conveyance path is inside the supply magazine. Because it does not cause large frictional resistance due to close contact with the stacked laminated sheets due to static electricity, etc., and also because the frictional resistance and resistance fluctuations with the guide plate and rollers caused by the restoring pressing force of the sheet 1- are small. Compared to the first conveyance path, the second conveyance path has extremely little conveyance resistance. As a result, sub-scanning can be performed at a stable feed rate with little fluctuation, and high-quality image recording without unevenness is possible.

When the image recording is completed in this manner, the sub-scanning roller 2 is rotated in the reverse direction to convey the sheet on which °C recording has been completed in the opposite direction to that during recording. When the trailing edge of the sheet reaches the main roller 12, the planetary roller 13, which had been retracted, is moved to the e position and holds the trailing edge of the sheet, and as the main roller 2 rotates, the planetary roller 13
The sheet is rotated at the same angular velocity to change the direction of travel of the sheet. When the planetary roller 13 reaches position g in Fig. 7, turn the lever]
4 is stopped, the C planetary roller 13 is stopped, the main roller 12 is driven, and the I? +1 feeds the recorded sheet into the receive magazine 4. When the main roller 12 feeds the recorded sheet into the receive magazine 4, the free play h10-ra]3 returns to the initial position d.

The number of sheets already stored in the receive magazine 4 is detected by means not shown, and the height of the laminated sheets in the receive magazine is estimated based on the detected number, and the planetary roller 14 is stopped according to the height. It is now time to determine the position g. This allows recorded sheets to be fed into the receive magazine without malfunction regardless of the number of stacked sheets.

While feeding the J, I, sheet into the receive magazine, the position of the play roller 13 is gradually changed from g to d, and the angle at which the sheet enters the receive magazine is controlled to gradually increase. It's okay.

Furthermore, by changing the direction of movement of the recorded sheet using the direction conversion unit 11, the recorded sheet can be directly fed to an automatic developing device, etc. installed outside the image recording apparatus, without storing it in a receive magazine. I can send it to you. In this case, when recording on the sheet is completed, the variable guide plate 23 is laid down horizontally and moved to the position shown in FIG. The planetary roller 13 is fixed at position e so that the sheet advances straight to the right, and by continuing to rotate the main roller 12 clockwise, the recorded sheet is delivered to the discharge port 24.
It can then be fed to an automatic developing device directly connected to the side.

[Other Embodiments] Next, other embodiments of the present invention will be explained. Figure 9 shows its constituent countries.

A guide plate 68 and a sub-scanning roller are provided along the outer periphery of the main roller 64 from the supply magazine 61.
The path leading to the rough 6 and the kite board 77 forms a first conveyance path, and the path from the sheet correction section 74 to the guide plate 73 and the guide plate 68
, the path leading to the sub-scanning roller 76 and the kite plate 77 forms a second transport path. The route j-1 has been set up so that the general public can gather together. As a result, the entire device has become a Combat I.

Next, the operation of this embodiment will be explained. Take out one sheet 62 from the supply magazine 61 with the suction cup 63,
One end of the sheet 62 is brought into contact with the circumference of the main roller 64. Next, the planetary roller 6 that was waiting for the initial installation i1c
5 rotates around the clock 3 until it reaches the position h, and the leading edge of the sheet is held between the main roller 64 and the planet opening 65. Next, the main roller 64 rotates in the counterclockwise direction, and at the same time When the levers 6 are rotated at the same angular velocity, the main roller 64 and the planetary rollers 65 change the direction of advance 1j of the leading edge of the sheet to the left in the figure while holding the leading edge of the sheet at the same position. When the planetary roller 65 returns to the position i, the driving of the lever 66 is stopped and only the rotational driving of the main roller 64 is continued. transported to. The leading edge of the sheet is sandwiched between a main roller 69 and a planetary roller 700, which are driven in synchronization with the main roller 64, and the sheet 62 is conveyed to the left by the rotation of the two main rollers. Next, the leading edge of the sheet is also held between the sub-scanning rollers 76, and is rotated at the same speed as the main roller 76 to convey the sheet. At this point, the sheet is still in the first conveyance path, and the rear end of the sheet is still in the supply magazine 61.
However, the rear end of the sheet eventually escapes from the Zaburai magazine 61, and the rear end flips up due to the mediating force of the sheet, causing the rear end to come into contact with the laminated sheet as shown in Figure 7+<. The end will be facing horizontally.

Once this state is reached, the main rollers 64 and 69 and the sub-scanning roller 76 are then rotated in the reverse direction to avoid moving the sheet 62 to the P direction, that is, to the second conveyance path. When the rear end of the sheet 62 comes into contact with the sheet straightening unit 74 and stops at °C, and the sheet is aligned, the main rollers 64 and 69 are rotated counterclockwise again to move the sheet in the sub-scanning direction. transport.

A sub-scanning roller 7 whose leading end of the sheet 62 rotates in the sub-scanning direction.
When the temperature reaches 6°C and can be held, the planetary rollers 65 and 70 are retracted to positions j and m, respectively, and the sea 1- is released from the restraint state.

While the sheet is sub-scanned along the second conveyance path with extremely low conveyance resistance, the optical unit 75 starts main scanning with a laser beam to record an image on the sheet-L. The recorded area on the sheet is sent out to the left in the figure, and due to its own weight, it sequentially hangs down in the Q direction and enters the guide plate 77. The guide plate 77 touches the hanging sheet or the side of the guide plate 77! L/1. t
They are installed at different locations and in mountainous areas to avoid causing unevenness in the sub-scanning during recording.

After recording is completed, the sub-scanning roller 76 is rotated in the reverse direction and the sheet is returned to the direction changing unit. When the rear end of the sheet reaches the main roller 69, the planetary rollers 70 return from position m to position 1 and clamp the sheet. At the same time as the C main roller 69 is rotated clockwise at the same angular velocity, the planetary roller 70 is rotated clockwise.
By rotating the sheet from position k to position k, the traveling direction of the sheet is changed to the R direction while the end portion of the sheet is being held. When the planetary roller 70 reaches the position, only the rotation of the lever 71 is stopped, and the main roller 69 continues to rotate to send the sheet into the receive magazine 78.

In this embodiment, the recorded sheet may not be sent to the receive magazine 78, but may be ejected to an automatic developing device or the like provided outside the main body of the recording apparatus. In this case, hold the recorded sheet with the planetary roller in the 1 device and turn the main port 6() into the
