BACKGROUND OF THE INVENTION
The present invention relates to an image output apparatus for recording and outputting an image on a film-shaped photosensitive material used for preparing a printing original plate, for example.
[0002]
[Prior art]
2. Description of the Related Art Conventionally, an image output apparatus has been used in which an image is recorded by exposing a film-shaped photosensitive material with light from a light emitting diode. The light-sensitive material on which the image is recorded becomes a printing original plate through an appropriate development process.
In one configuration example of this type of image output apparatus, a cylindrical rotating drum that is rotated around an axis, and an axial direction of the rotating drum are provided so as to be movable, and exposure is performed toward the outer surface of the rotating drum. And a recording head for generating light for use. The photosensitive material on which an image is to be recorded is wound around and supported on the outer peripheral surface of the rotating drum. This photosensitive material is subjected to main scanning by light from the recording head as the rotating drum rotates at high speed, and sub-scanning by light from the recording head as the recording head moves at low speed along the axial direction of the rotating drum. Receive. Therefore, if the light generated by the recording head is modulated with image data, a latent image corresponding to the image data is written on the surface of the photosensitive material.
[0003]
There are a step exposure method and a spiral exposure method as exposure methods for recording on the photosensitive material. In the step exposure method, the recording head is sent in the sub-scanning direction for a predetermined line every time the photosensitive material goes around. As a result, an image is recorded on the surface of the photosensitive material by scanning lines orthogonal to the sub-scanning direction. On the other hand, in the spiral exposure method, the recording head is continuously moved in the sub-scanning direction. Therefore, the photosensitive material on the surface of the rotating drum is scanned in a spiral shape. Therefore, the scanning line is inclined with respect to the direction orthogonal to the sub-scanning direction.
[0004]
In particular, when using a multi-beam type recording head that performs drawing of a plurality of lines in parallel using a plurality of beams, the moving speed of the recording head is high, and thus the tilt angle may become so large that it cannot be ignored.
FIG. 6A is an illustrative view showing a slightly exaggerated example of image recording by the spiral exposure method. An image is recorded on the surface of the rectangular photosensitive material 1 by a plurality of lines 2 inclined with respect to a direction orthogonal to the sub-scanning direction. In the drawing by the inclined line 2, a rectangular figure is recorded as a parallelogram.
[0005]
Therefore, conventionally, as shown in FIG. 6 (b), by correcting the recording timing of the image on each line 2, a distortion correction process for recording a rectangular figure as a rectangle on the photosensitive material has been performed. Yes.
The photosensitive material 1 is punched with punch holes 3, 4, 5 for alignment during printing or printing. These punch holes 3, 4 and 5 are perforated along one side along the main scanning direction. For example, the punch hole 4 at the center is circular, and the punch holes 3 and 5 at both ends are elongated. Yes. These punch holes 3, 4 and 5 are punched by a punch mechanism provided in association with the rotating drum.
[0006]
[Problems to be solved by the invention]
However, generally, the punch mechanism provided in association with the rotating drum is configured to punch so that the punch holes are arranged along the rotating direction of the rotating drum. Therefore, the line 2 is inclined with respect to the punch holes 3, 4, and 5. As a result, the arrangement direction of the punch holes 3, 4, and 5 and the image recorded on the photosensitive material 1 are inclined with respect to each other. It is in a state. Therefore, there has been a problem that the alignment at the time of baking or the like is complicated.
[0007]
Moreover, since the feed speed of the recording head is controlled depending on the resolution of the image to be recorded, the inclination angle of the line 2 depends on the resolution. Therefore, even if the punch holes 3, 4, 5 are perforated so as to be arranged at a constant inclination angle with respect to the direction orthogonal to the sub-scanning direction, the punch holes 3, 4, 5 formed in this way It is only possible to have an appropriate positional relationship only with respect to an image recorded at a certain resolution.
[0008]
Accordingly, an object of the present invention is to provide an image output apparatus having a configuration capable of solving the above technical problem and punching a punch hole at an appropriate position corresponding to the image output position.
[0009]
[Means for Solving the Problems and Effects of the Invention]
In order to achieve the above object, an invention according to claim 1 is an image output apparatus for recording an image by scanning a photosensitive material carried on a rotating drum in a spiral shape.

[0010]
According to this configuration, when an image is recorded on the photosensitive material in a tilted state by spiral exposure, the punch mechanism is moved in the axial direction of the rotating drum according to the tilt angle of the image. Thereby, a punch hole is punched at a position corresponding to the inclination angle of the image. Therefore, even when an image is recorded with an inclination, punch holes can be punched at a substantially constant relative position with respect to the image output position.
[0011]
Note that the image output apparatus preferably includes a distortion correction processing unit that corrects image distortion caused by spiral exposure.

The image output apparatus according to claim 1, wherein the position of the punch hole in the rotational axis direction of the rotary drum is controlled.
[0013]
When an image is recorded by spiral exposure, the tilt angle of the scanning line depends on the resolution of the image. Therefore, if the punch mechanism moving unit is controlled based on the resolution information input from the resolution input unit, a punch hole can be punched at a position corresponding to the inclination angle of the image.
The resolution input means may be a manual input means such as an operation panel, or may be a device that automatically generates resolution information such as a computer.
[0014]
Moreover, in addition to the structure of Claim 1 or Claim 2, it is preferable to further include a rotational position control means for controlling the rotational position of the rotating drum when punch holes are punched. In this case, it is preferable that the rotation position control means controls the rotation position of the rotating drum based on the resolution information.
With this configuration, the punching position of the punch hole can be adjusted not only in the rotation axis direction of the rotating drum but also in the rotating direction of the rotating drum. Therefore, it is possible to punch holes at appropriate positions with respect to the image formed on the photosensitive material in an inclined state.
According to a third aspect of the present invention, there is provided an image output device that scans a photosensitive material carried on a rotating drum in a spiral shape and records an image on the photosensitive material, and an image to be recorded on the photosensitive material carried on the rotating drum. The resolution input means for inputting the resolution information of the image, and the image is modulated based on the image data while continuously moving along the axial direction of the rotating drum at a speed corresponding to the resolution information input from the resolution input means. By generating a plurality of recording beam lights in parallel toward the photosensitive material, an image is recorded on the photosensitive material in a rectangular image output area inclined with respect to the axial direction of the rotating drum. a recording head, a punching mechanism that punches holes in the photosensitive material, on the basis of the resolution information inputted from the resolution input means, a plurality of paths according to the inclination angle of the image recorded on the photosensitive material Ji hole and a punching position control means for controlling the punch mechanism so that the punch hole piercing position as drilled in the photosensitive material arranged parallel to one side of the image output area of the rectangle is formed An image output apparatus including the image output apparatus.
[0015]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
FIG. 1 is a conceptual diagram showing a basic configuration of an image output apparatus according to an embodiment of the present invention. This image output apparatus is an apparatus for forming a latent image on the photosensitive material F by spirally exposing the photosensitive material F wound and supported on the outer peripheral surface of the cylindrical rotary drum 10 by the recording head 11. . The light-sensitive material F on which the latent image has been formed becomes a printing original plate through an appropriate development process.
[0016]
The rotary drum 10 is rotated at high speed around its axis (rotation axis) by a main scanning motor M1 formed of a stepping motor. Information about this rotation is detected by the encoder 12.
The recording head 11 is provided so as to face the outer peripheral surface of the rotary drum 10, and is mounted on a movable table 14 coupled to a ball screw 13 disposed along the axial direction A 1 of the rotary drum 10. The ball screw 13 is driven by a sub-scanning motor M2 that is a stepping motor, whereby the recording head 11 moves linearly along the axial direction A1 of the rotary drum 10.
[0017]
The recording head 11 includes, for example, a plurality of light emitting diodes (LEDs), and is a multi-beam type that generates a plurality of recording beam lights for drawing a plurality of lines in parallel toward the rotating drum 10. It is configured. A drive signal for driving each light emitting diode is supplied from the control device 20.
With this configuration, while the rotary drum 10 is rotated at a high speed, the recording head 11 moves at a low speed along the axial direction A1 of the rotary drum 10, and the recording beam light generated from the recording head 11 is sensitive to light. The image is recorded while scanning the surface of F in a spiral shape.
[0018]

The output signal of the encoder 12 drives the head control unit 21 that controls the exposure start timing by the recording head 11, the lateral feed control unit 22 that controls the operation of the driver 16 that drives the sub-scanning motor M2, and the main scanning motor M1. This is used in the servo mechanism 23 that controls the operation of the driver 15 that performs the operation. The head controller 21 starts the exposure operation for each line when the rotational position of the rotary drum 10 reaches a predetermined position based on the output signal of the encoder 12. Further, the lateral feed control unit 22 controls the driver 16 so that the recording head 11 is moved in synchronization with the rotation of the rotary drum 10. Further, the servo mechanism 23 feedback-controls the driver 15 so that the rotary drum 10 rotates at a constant speed.
[0019]
The control device 20 includes an image processing unit 25 for processing image data input from a raster image processor (RIP) 30 such as a computer via an appropriate interface (I / F), and the image processing. A light-emitting diode driver 26 that controls the light-emitting diodes of the recording head 11 based on the image data processed by the unit 25, and a distortion correction unit 27 (distortion correction) for correcting image distortion (see FIG. 6) caused by spiral drawing. Processing means). Further, the control device 20 is provided with a CPU 28 having an input / output (I / O) interface unit, and an operation panel 35 is connected to the CPU 28.
[0020]
A pair of punch mechanisms 41 and 42 are provided in the vicinity of one end of the rotating drum 1 in order to punch punch holes in the photosensitive material F for alignment during printing and printing. The pair of punch mechanisms 41 and 42 are coupled to ball screws 43 and 44, respectively, and are moved along the axial direction A1 of the rotary drum 1 by motors M3 and M4 that drive the ball screws 43 and 44, respectively. It has come to be. Thereby, each punch mechanism 41 and 42 can change the punching position of the punch hole with respect to the axial direction A <b> 1 of the rotary drum 1. That is, the motors M3 and M4 and the ball screws 43 and 44 correspond to punch mechanism moving means.
[0021]
In order to control the operations of the drivers 17 and 18 that drive the motors M3 and M4, the control device 20 includes a punch mechanism lateral feed control unit 45. The control device 20 is provided with a punch operation control unit 46 for controlling the punching operation of the punch mechanisms 41 and 42.
FIG. 2 is a cross-sectional view for explaining the attachment structure of the punch mechanisms 41 and 42. Rotating shafts 10a and 10b are attached to both end surfaces of the rotating drum 10 along the axis thereof. The rotary shafts 10a and 10b are pivotally supported by bearings 52 attached to opposite side walls of the main body frame 51, respectively.
[0022]
In the vicinity of the upper part of the main body frame 51, punch mechanisms 41 and 42 are juxtaposed along the rotation direction of the rotary drum 11 at a position facing one end of the rotary drum 10 (in FIG. 2, the front side punch mechanism). Only.) The edge portion 10A of the rotating drum 10 protrudes in a cylindrical shape at one end portion of the rotating drum 10, and punches holes are formed in the photosensitive material F at predetermined positions (three positions in this embodiment) spaced in the circumferential direction. A notch 56 is formed to allow the arrangement of the punch mechanisms 41 and 42 when the hole is drilled (see FIG. 1).
[0023]
The punch mechanisms 41, 42 have a main body portion 60, a punch portion 61 attached to the punch attachment portion 64 of the main body portion 60, and a die portion 62 formed integrally with the main body portion 60. The punch unit 61 includes a punch 65 and a punch solenoid 66 that moves the punch 65 back and forth. In the punch attachment portion 64 of the main body portion 60, a passage hole 63 for allowing the punch 65 to pass is formed at a position corresponding to the punch 65. A die hole 67 for receiving the punch 65 is formed at a position facing the passage hole 63 in the die portion 62.
[0024]
A gap 68 that can receive the edge of the photosensitive material F is formed between the die portion 62 and the punch attachment portion 64. When the punch solenoid 66 is excited with the edge of the photosensitive material F inserted into the gap 68, the punch 65 is biased upward and punches a punch hole in the photosensitive material F in cooperation with the die portion 62. To do. When the punch solenoid 66 is demagnetized, the punch 65 is returned to the lower position by a spring (not shown). The punch operation controller 46 (see FIG. 1) controls the excitation / demagnetization of the punch solenoid 66.
[0025]
As for the shape of the punch 65, the one corresponding to the punch mechanism 41 is an axial body having a circular cross section, and the one corresponding to the punch mechanism 42 is an axial body having an oval cross section.
The main body 60 is movable along the rail 70 attached to the main body frame 51 in the axial direction A1 of the rotary drum 10. Ball screws 43 and 44 are screwed into the main body 60, and the ball screws 43 and 44 are rotationally driven by the motors M3 and M4, whereby the main body 60 is moved in the axial direction A1 of the rotary drum 10. It is designed to move along. Thereby, the drilling position by the punch 65 is variable along the axial direction A1.
[0026]
FIG. 3 is an illustrative view showing a state in which punch holes are formed in the photosensitive material F. FIG. On the photosensitive material F, an image is recorded in a rectangular image output area 80 that is inclined with respect to the axial direction A1 of the rotary drum 10. Three punch holes P1, P2, and P3 are arranged and perforated in parallel with the side 81 along the end face of the rotary drum 10 in the image output region 80. The central punch hole P2 is circular, and the punch holes P1 and P3 on both sides are oval. That is, the central punch hole P2 is punched by the punch mechanism 41, and the punch holes P1 and P3 on both sides are punched by the punch mechanism 42.
[0027]
As understood from the fact that the longitudinal direction of the oval punch holes P1 and P2 is parallel to the rotation direction R1 of the rotary drum 10, the punch mechanisms 41 and 42 have their punching positions along the axial direction A1 of the rotary drum 10. However, there is no mechanism for rotating the direction of the punch hole.
When positioning at the time of printing or printing, positioning pins having an oval cross section are inserted into the punch holes P1 and P3, and positioning pins having a circular cross section are inserted into the punch holes P2. At this time, the oval punch holes P1 and P3 are subjected to stress from the positioning pin, but in reality, the inclination angle θ with respect to the rotation direction R1 of the image output region 80 is sufficiently small, and this stress is a problem. There is no fear of becoming.
[0028]
FIG. 4 is an illustrative view showing a state in which a positioning pin 90 having an oval cross section is inserted into an oval punch hole P1. The protrusion length Δ of the positioning pin 90 from the punch hole P1 is determined by the length h of the linear portion (straight portion in plan view) 91 of the positioning pin 90 and the inclination angle θ of the punch holes P1 to P3 with respect to the rotation direction R1. It is given by the following equation (1).
[0029]
Δ = h · tanθ (1)
On the other hand, tan θ is, for example, 2 mm as the scanning width (the width of the image recorded by the recording head 11 in a single scan. If multiple lines are recorded in parallel, it is proportional to the number of lines). When the diameter of the rotating drum 10 is 400 mm, the following equation (2) is obtained.
[0030]
tan θ = 2 / 400π = 0.00159 (2)
Therefore, for example, if h is about 5 mm,
Δ = 0.00795mm ≒ 8μm ・ ・ ・ ・ ・ ・ (3)
It becomes. If the protrusion length Δ is such a value, there is no possibility that the photosensitive material F will be subjected to a large stress.
[0031]
FIG. 5 is an illustrative view for explaining the principle for determining the punch hole formation position. For example, it is assumed that the rectangular area OP is recorded on the photosensitive material F in a state where the rectangular area OP is rotated clockwise by an angle θ1. FIG. 5 also shows a reference position OPref, which is the position of the rectangular area OP that is not rotated. The left side of the rectangle at the reference position OPref is a line segment that passes through the formation positions of the punch holes P1 to P3 when the image is formed on the photosensitive material F without causing inclination (that is, in the case of step exposure). Yes.
[0032]
The upper right end of the reference position OPref is the origin (0, 0), and the horizontal length of the rectangular area OP is a. The vertical length 2πr of the image region 80 is given by 2πr = 2π (R + 2d) where R is the diameter of the rotating drum 10 and d is the thickness of the photosensitive material F. Therefore, when one point (a, b) (punching position of the punch hole) on the left side of the reference position OPref is moved to the point (A, B) by the rotation of the angle θ1, the following equations (4) to (7) The formula holds.
[0033]
[Expression 1]

[0034]
Here, θ2 represents an angle formed by the right side of the reference position OPref and a straight line connecting the origin (0, 0) and the point (a, b), and n represents the number of recording beams generated from the recording head 11. P represents the beam pitch in the sub-scanning direction at the specified resolution.
Therefore, by providing resolution information to the control device 20 from the raster image processor 30 or the operation panel 35, the punching positions of the punch holes P1, P2, and P3 corresponding to the inclination angle of the image are obtained.
[0035]
Therefore, in this embodiment, the CPU 28 obtains the resolution information and calculates the punching positions of the punch holes P1, P2, and b3. The calculation result is given to the servo mechanism 23 and the punch mechanism lateral feed control unit 45. The servo mechanism 23 controls the operation of the main scanning motor M1 via the driver 15 based on the commanded punching position, and controls the rotational position of the rotary drum 10. Further, the punch mechanism lateral feed control unit 45 controls the motors M3 and M4 via the drivers 17 and 18 based on the commanded punching position. Thereby, the position regarding the axial direction A1 of the punch mechanisms 41 and 42 is controlled. After the rotary drum 10 and the punch mechanisms 41 and 42 are positioned in this way, the punching operation control unit 46 controls the punching operation of the punch mechanisms 41 and 42, so that the punch holes P <b> 1 to P <b> 1 are positioned at appropriate positions on the photosensitive material F. P3 will be drilled. The punch holes P1 to P3 are not drilled at the same time, but are sequentially drilled one by one by adjusting the rotational position of the rotary drum 10 and the position of the punch mechanisms 41 and 42 in the axial direction A as needed.
[0036]
As described above, in this embodiment, the CPU 28, the punch mechanism lateral feed control unit 45, and the like correspond to the punching position control means. Further, the CPU 28, the servo mechanism 23, and the like correspond to the rotational position control means.
Although one embodiment of the present invention has been described, the present invention can also be implemented in forms other than those described above. For example, in the above embodiment, three punch holes are drilled, but the number of punch holes to be drilled is arbitrary. Further, in the above-described embodiment, the notch 56 is formed in the end edge 10 </ b> A of the rotating drum 10, but such a notch is not formed, and the edge of the photosensitive material F is the edge of the rotating drum 10. The sensitive material F may be mounted on the rotating drum 10 so as to protrude from one end. In the above embodiment, the recording head 11 is of a multi-beam type capable of generating a plurality of recording light beams. However, the recording head 11 is an apparatus having a recording head that generates a single recording light beam. The present invention can also be applied to.
[0037]
In addition, various design changes can be made within the scope of matters described in the claims.
