Abstract

PROBLEM TO BE SOLVED: To improve appearance by preventing space from being made in the case of recording an original image all over the recording area of a photosensitive material. SOLUTION: In the case of recording the original image on the entire recording surface of the photosensitive material 16, for example, in the case of unmagnified recording, magnification is 100% naturally when the size of the original and the size of the photosensitive material 16 are the same area. However, the space is made around the recorded image when the image is recorded in an unmagnified state with the accuracy of the dimension (longitudinal and lateral dimension) of the photosensitive material 16 and the accuracy of setting the magnification by the movement of a lens unit 38B. Therefore, exposure is performed at somewhat magnified magnification with respect to the magnification designated in an exposure being center reference.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an image recording apparatus for exposing a photosensitive material on an original image to obtain a copied image.

[0002]

2. Description of the Related Art An image recording apparatus is known which performs an image recording process using two kinds of image recording materials, for example, a photosensitive material and an image receiving material.

In this type of image recording apparatus, the light-sensitive material and the image-receiving material are housed in rolls each wound in a magazine whose inside is shielded from light, and are sequentially withdrawn each time image recording processing is performed. used. Further, the image recording apparatus is provided with a water coating section for coating the image forming solvent on the photosensitive material, and further, from a heating drum and an endless pressure welding belt which is in pressure contact with the outer circumference of the heating drum and rotates together with the heating drum. The thermal development transfer section is arranged.

The photosensitive material, which is pulled out from the magazine by a predetermined size and cut, is exposed with an image while being nipped and conveyed by conveying rollers, and further, water as an image forming solvent is applied in the water application section, and then the heat development transfer section. Sent to. On the other hand, like the photosensitive material, the image receiving material is pulled out from the magazine by a predetermined size and cut, and is fed to the heat development transfer section in synchronization with the photosensitive material by the conveying roller. In the heat-development transfer section, the light-sensitive material coated with water is superposed with the image-receiving material, and in this state, the light-sensitive material is closely wound around the outer periphery of the heating drum. Further, both materials are sandwiched and conveyed between the heating drum and the endless pressure contact belt so that the photosensitive material is thermally developed and an image is transferred to the image receiving material, and a predetermined image is formed (recorded) on the image receiving material. is there.

In such an image recording apparatus, the reflective original is usually positioned on the glass surface provided on the upper surface of the main body of the apparatus, the image is scanned by line scanning, the image is exposed on the photosensitive material, and then the image is received on the image receiving material. Is to be transcribed and recorded.

[0006]

However, for example, when recording an image at the same size, the vertical and horizontal dimensions of the photosensitive material and the vertical and horizontal dimensions of the original image may not always match. The causes include the size accuracy of the photosensitive material, the position accuracy of the zoom lens for changing the magnification, and the change of the optical path length (displacement of the photosensitive material in the thickness direction, etc.). In such a case, it is not noticeable if the original image is recorded larger than the recording area of the photosensitive material, but conversely, if the original image is recorded smaller than the recording area of the photosensitive material, a margin portion is generated and Positioning accuracy of the photosensitive material, conveyance positioning accuracy of the photosensitive material, and further, when the image exposed on the photosensitive material is transferred to the image receiving material, if the transfer positional accuracy is not good,
The margins are enlarged and slanted, which makes them very unattractive.

There is a case in which a so-called edged image is formed in which a margin of a predetermined width is intentionally provided around the image, and this edge determines a predetermined width of a predetermined ratio with respect to the image area. . On the other hand, the margin is unbalanced because it has no correlation with the image area unlike the consciously provided edge.

In consideration of the above facts, the present invention can provide an image recording apparatus capable of improving the appearance without producing a blank when an original image is recorded over the entire recording area of a recording material. Is the purpose.

In addition to the above object, it is another object of the present invention to provide an image recording apparatus which can surely provide a blank of a predetermined width in the recording area of the photosensitive material when the original image is an edged image.

[0010]

According to a first aspect of the present invention, there is provided an image recording device which obtains a copied image by exposing an original image onto a photosensitive material, and the original image is recorded on the entire surface of the photosensitive material. First magnification setting means for setting a first exposure magnification, and first magnification setting means for setting the first magnification setting means so that a blank space does not occur around an image recorded on the photosensitive material.
Second magnification setting means for setting the exposure magnification of the second exposure magnification to a predetermined value, and the magnification set by the first or second magnification setting means with reference to the center of the original. An exposure unit that exposes the original image.

According to a second aspect of the present invention, there is provided an image recording device which exposes a document image on a photosensitive material to obtain a copied image.
When the original image is recorded on a photosensitive material, a marginless mode setting means for setting a marginless mode so that a margin is not formed around an image exposed on the photosensitive material, and the marginless mode setting means If the borderless mode is not set with, the original image is recorded on the entire surface of the photosensitive material.
When the first exposure magnification is automatically set and the borderless mode is set, a magnification setting means for setting the set first exposure magnification to a second exposure magnification obtained by increasing a predetermined value; Exposure means for exposing the original image at the magnification set by the magnification setting means with reference to the center of the original.

According to the first aspect of the invention, the first magnification setting means sets the first exposure magnification for recording the original image on the entire surface of the photosensitive material. Here, in the first exposure magnification setting, a magnification is set such that the image size and the photosensitive material size are calculated in agreement (for example, 100% for L size → L size, 1 for E size → L size).
08%, etc., see Table 1). However, if the sizes are the same in calculation, there is a possibility that a blank space may appear on the entire circumference or a part thereof due to machine difference, positioning error, and the like. Therefore, the second magnification setting means changes the set first exposure magnification to a second exposure magnification which is increased by a predetermined value so that no margin is generated around the image recorded on the photosensitive material. You can

By performing exposure based on the second exposure magnification set by the second magnification setting means, an image slightly larger than a desired size is recorded on the photosensitive material. As a result, no margin is produced in the vicinity of the peripheral edge of the photosensitive material, and even if the image is recorded with a slight inclination, it can be made almost inconspicuous.

According to the second aspect of the present invention, when the original image is recorded on the photosensitive material, it is determined whether or not the marginless mode is set so that no margin is formed around the image on the photosensitive material. Set. In this setting, if the borderless mode is not set, the designated magnification is set as it is as the magnification for scanning exposure. Further, when the borderless mode is set, a predetermined enlargement magnification is set as the magnification for scanning exposure with respect to the designated magnification.

As described above, since the magnification is changed depending on whether the borderless mode is set or not, irregular margins (edges) are formed around the image exposed on the photosensitive material and the appearance is deteriorated. In this case, by setting the borderless mode, it is possible to prevent the image from being enlarged due to the increase of the exposure magnification and the occurrence of irregular margins around the image on the photosensitive material.

As the light-sensitive material used in the image recording apparatus of the present invention, a latent image obtained by imagewise exposure is transferred to an image-receiving material by heat development transfer in the presence of an image-forming solvent to obtain a visible image. A so-called photothermographic material can be used.

The photothermographic material basically has a photosensitive silver halide, a reducing agent, a binder, and a dye-donor compound (which may also serve as a reducing agent) on a support, and further needs An organic metal salt oxidizing agent and the like can be added depending on the case.

The above-mentioned photothermographic material may give a negative image or a positive image upon exposure. As a method of giving a positive image, a method of directly using a positive emulsion as a silver halide emulsion (a method using a nucleating agent and a light fog method are available), a dye that emits a positive diffusible dye image Any of the methods using a donor compound can be adopted.

Examples of the photothermographic material of the type which gives a positive image include those disclosed in JP-A-6-161070 and JP-A-6-161070.
No. 289555, and as the photothermographic material of the type which gives a negative image, for example, those described in JP-A Nos. 5-181246 and 6-242546 can be used. it can.

Further, the image forming solvent in the present invention includes, for example, water, and this water is not limited to so-called pure water but includes water in the meaning which is widely and commonly used. Further, a mixed solvent of pure water and a low boiling point solvent such as methanol, DMF, acetone, and diisobutyl ketone may be used. Further, it may be a solution containing an image formation accelerator, an antifoggant, a development terminator and a hydrophilic thermal solvent.

There is. This position (the solid line position in FIG. 3) is the scanning start position, and the reflected light when moving from the scanning start position toward the left end of the mounting table 12A is reflected by the first mirror 204.
It is supposed to be received at.

The first mirror 204 is attached to the bracket 200 in a state of being inclined by 45 ° with respect to the machine base 12. Therefore, the optical axis L that is vertically incident on the first mirror 204 is deflected by 90 ° and is set as a horizontal optical axis toward the left side of the device.

In the extending direction of the horizontal optical axis L,
The mirror unit 38D is arranged. The mirror unit 38D includes two mirrors (second mirror 206,
The third mirror 208) is fixed to the bracket 210, and the relative positions thereof are determined so as to be in the vertical direction with respect to each other, and they are inclined by 45 °.

Therefore, the second mirror 206, which has received the light of the horizontal optical axis from the first mirror 204, has its reflected optical axis L vertical and is made incident on the third mirror 208. There is. The reflecting surface of the third mirror 208 converts it to the horizontal optical axis L again, and guides it to the mirror unit 38C arranged in the right direction of the device.

The mirror unit 38D is arranged to move in parallel with the movement of the halogen lamp unit 38A and in the same direction. This moving amount is 1 of the moving amount of the halogen lamp unit 38A.
It is / 2. For example, halogen lamp unit 3

The lens unit 38B is movable along the optical axis L, and is capable of changing the magnification of the copied image with respect to the original. The lens unit 38C is movable in parallel with the horizontal optical axis L in order to adjust the optical path length for matching the focal lengths due to the change in magnification.

FIG. 4 shows an optical system in which the relationship between the magnification and the focal length is simplified. The magnification change in the image recording apparatus 10 of the present embodiment employs different methods in the scanning direction (the moving direction of the halogen lamp unit 38A) and the width direction thereof. Changing the magnification in the width direction is a simple optical method, and changing the magnification in the X direction is performed optically.
This is done by changing the scanning speed.

The optical system will be described below.
When the focal length of the lens unit 38B is f, the distance between the original and the lens unit 38B is a, and the distance between the lens unit 38B and the copied image is b, (1 / a) + (1 / b) = 1
There is a relationship of / f. Therefore, when the lens unit 38B is brought closer to the original 11 for changing the magnification, the value of a becomes smaller, and the value of b needs to be increased accordingly.

Therefore, in FIG. 3, when the lens unit 38B moves along the optical axis L at the designated magnification,
Along with this, the lens unit 38C moves in the opposite direction.

The photosensitive material 16 conveyed to the heat development transfer section 104 is sent between the bonding roller 120 and the heating drum 116, and the image receiving material 108 is the photosensitive material 1.
In synchronism with the conveyance of 6, the photosensitive material 16 is fed between the laminating roller 120 and the heating drum 116 in a state of being preceded by a predetermined length so as to be superposed.

A halogen lamp 132 is arranged inside the heating drum 116 so that the surface of the heating drum 116 can be heated.

The endless pressure contact belt 118 is wound around four winding rollers and is heated by the heating drum 116.
It is wrapped around about half the circumference of
It is in a pressure contact state with a predetermined force.

A bending guide roller 142 is provided below the heating drum 116 downstream of the endless pressure contact belt 118 in the material supply direction.
Is arranged. A peeling claw 154 is rotatably supported by a shaft below the heating drum 116 on the downstream side of the bending guide roller 142 in the material supply direction.

Here, when a specific photograph size is selected as the original 11 during the scanning exposure of the present embodiment, the center of the original 11 is used as a reference for exposure at a predetermined magnification.

That is, if the document size is known, the center position of the document can be recognized by calculation. Since the exposureable distance of the image in the scanning direction is determined by the magnification, this length is divided into left and right from the calculated center position, and the left end and the right end are determined. An image with the center of the original image as a reference can be obtained by scanning and exposing the determined range.

By the way, when an original image is recorded on the entire recording surface of the photosensitive material 16, for example, when recording is performed at the same size,
If the original size and the size of the photosensitive material 16 are the same area, the magnification is naturally 100%. However, the accuracy of the dimensions (vertical and horizontal dimensions) of the photosensitive material 16, the lens unit 38B
When an image is printed at the same size due to the precision of the magnification setting due to the movement of the, etc., a margin may occur around the recorded image.

For this reason, the exposure is performed at a slightly enlarged magnification with respect to the magnification designated at the time of exposure with the center as the reference. This magnification change is predetermined as shown in Table 1.

[0059]

[Table 1]

As shown in Table 1 above, in the case of no border, a slight enlargement ratio (for example, 104%) is set with respect to the standard magnification (for example, 100%). Further, in the case where there is an edge in Table 1 above, it is a standard magnification, that is, the magnification when the entire surface of the photosensitive material 16 is exposed in accordance with the original size,
In addition to this, when the magnification is manually set, the above setting is ignored and scanning exposure is performed at the designated magnification.

The presence of an edge shown in Table 1 means that when the document has an edge (margin), the entire surface of the photosensitive material 16 is exposed while leaving the edge as it is. The borderless setting can be performed by operating a key on an operation display panel (rimless mode setting means) not shown.

Next, the operation of the present embodiment will be described. First, in the case of copying a reflection original, when the start key is operated after the predetermined settings (magnification, number of sheets, etc.) are completed, the following image recording processing is started.

That is, with the photosensitive material magazine 14 set, the nip roller 18 is operated and the photosensitive material 16
Are pulled out by the nickel roller 18. Photosensitive material 1
When 6 is pulled out by a predetermined length, the cutter 20 operates and the photosensitive material 16 is cut into a predetermined length.

After the operation of the cutter 20, the photosensitive material 16 is
The sheet is conveyed to the exposure unit 22 with its photosensitive (exposure) surface facing upward. At the same time when the photosensitive material 16 is conveyed, the exposure device 38 operates to scan and expose the photosensitive material 16 located in the exposure section 22.

After the exposure is started, after the exposed photosensitive material 16 is once sent to the switchback section 40,
The water is applied to the water application unit 62 by the reverse rotation of the transport rollers 24, 23, 21.

In the water application section 62, water is applied to the photosensitive material 16 and sent to the heat development transfer section 104.

On the other hand, when the scanning exposure of the photosensitive material 16 is started, the image receiving material 108 is also pulled out from the receiving material magazine 106 by the nip roller 110 and conveyed. When the image receiving material 108 is pulled out by a predetermined length, the cutter 112 operates to cut the image receiving material 108 into a predetermined length.

After the cutter 112 is operated, the cutter 112 is guided by the image receiving material transport unit 180 and is in a standby state immediately before the heat development transfer unit 104.

In the heat development transfer section 104, when it is detected that the photosensitive material 16 has been fed between the outer periphery of the heating drum 116 and the bonding roller 120, the conveyance of the image receiving material 108 is restarted and the bonding roller 120 is restarted. And the heating drum 116 is activated.

The photosensitive material 16 and the image receiving material 108, which are superposed by the laminating roller 120, remain in the superposed state, and the heating drum 116 and the endless pressure contact belt 11 are kept.
8 and the heating drum 116 is conveyed over almost half the circumference. As a result, the photosensitive material 16 and the image receiving material 1
08 is heated to release a movable dye, and at the same time, this dye is transferred to the dye fixing layer of the image receiving material 108 to obtain an image.

After that, when the photosensitive material 16 and the image receiving material 108 are nipped and conveyed and reach the lower portion of the heating drum 116, the peeling claw 154 is moved, and the photosensitive material 16 is conveyed by a predetermined length ahead of the image receiving material 108. Peeling claw 15 on the tip of
4 engages the leading end of the photosensitive material 16 to the heating drum 116.
Is peeled from the outer periphery of.

Further, the photosensitive material 16 is the bending guide roller 1
It is wound around 42 and accumulated in a waste photosensitive material storage box 178.

On the other hand, the heating drum 1 is separated from the photosensitive material 16.
Image receiving material 108 moving while being in close contact with 16
Is sent to the peeling roller 174 and peeled.

The image receiving material 108 peeled from the outer periphery of the heating drum 116 by the peeling claw 176 is further wound around the peeling roller 174, moved downward, and guided by the material receiving guide 170 and conveyed by the material receiving discharge roller 172. It is then discharged to the tray.

Here, in the present embodiment, in the case of image recording processing at a fixed magnification, that is, in the case of image recording at a magnification such that an image is recorded on the entire surface of the photosensitive material 16 based on the document size and the output size. In addition, different magnifications are set depending on whether the borderless mode is set or not (see Table 1).

When the borderless mode is not set, the processing is performed according to the calculated standard magnification. That is,
For example, when the original size and the output size 16 are the same size, a magnification of 100% is set in calculation, and the actual exposure is also performed at a magnification of 100%. Therefore, when the original material is an edged image, the image recording is performed with the predetermined edge provided on the photosensitive material 16 without fail.

On the other hand, when the image is recorded on the photosensitive material 16 at a magnification of 100%, the magnification setting positioning accuracy by the lens unit 38B, the positioning accuracy of the photosensitive material 16 in the thickness direction at the exposure portion 20, the photosensitive material 16 If there is no error in the dimensional accuracy of, the image is recorded on the entire surface of the photosensitive material 16. However, if there is an error (including a tolerance) in the above accuracy, a blank space is generated around the image area. This margin width is irregular and looks bad (see FIG. 5A). Therefore, in the present embodiment, in order to surely eliminate such margins, a predetermined enlargement ratio is set for the magnification calculated by the standard magnification, and the image recording process is performed at this enlargement ratio.

As a result, the peripheral edge of the image exposed on the photosensitive material 16 and transferred to the image receiving material 108 is the image receiving material 108.
It is located on the outside of the peripheral edge of and can eliminate the margin. Further, even if this image is slightly inclined, this inclination is not noticeable and the appearance can be improved (see FIG. 5B).

[0079]

As described above, the image recording apparatus according to the present invention can improve the appearance without producing a blank when an original image is recorded over the entire recording area of the photosensitive material. Has excellent effect.

In addition to the above effects, when the original image is a framed image, a margin of a predetermined width can be surely provided.
