2. Description of the Related Art For example, a photosensitive material such as an original film for printing or a printing plate is provided with punch holes for alignment during printing and alignment during printing. For example, in order to prevent mutual image misalignment of a plurality of color plates (for example, four color plates of yellow, magenta, cyan, and black) during color printing, the positional relationship between the punch holes and the image is a plurality of color plates. Punch holes are made in each color plate so that they are the same. Conventionally,
When performing punching of this kind, the punching holes and the positions of the images are aligned by registering each of the plurality of sensitive materials for each color.

In order to omit this registration work, an image recording apparatus has already been proposed which punches holes when recording an image on a photosensitive material. This image recording apparatus has a recording drum on which a photosensitive material obtained by cutting a roll-shaped photosensitive material is arranged on the peripheral surface, and a pair of punch units arranged on the peripheral surface of the recording drum.

The discharge mechanism 16 switches back the photosensitive film by the roll 16a, and discharges the photosensitive film to the automatic developing device 2 by the roll 16b with the photosensitive (emulsion) side facing down. This is because the photosensitive surface needs to face downward when developing.

As shown in FIGS. 3 and 4, the recording drum 11 has rotating shafts 11a and 11b which project to both sides. The rotating shafts 11a and 11b are rotatably supported by bearings 18 provided on a body frame (not shown).

In step S2, the input of the image size, the processing mode, the punch hole arrangement direction, the image data, etc. is accepted from the input key 7 or the external device. Here, the processing mode includes an automatic mode and a manual mode. In the automatic mode, the punch hole arrangement direction is automatically switched according to the image size, and a plurality of punch holes are formed along the long side of the photosensitive film F. It is a mode to open. The manual mode is a mode in which the punch hole arrangement direction is switched according to an instruction from the input key 7.

In step S3, the exposure start command is awaited.
This exposure start command is issued from the operator via the input key 7.
Alternatively, it is given from an external device via the LAN interface 51. In step S4, by the supply mechanism 12,
The roll film is supplied from the film magazine 10 to the recording drum 11. In step S5, the film is cut by the cutter 15 according to the size of the image obtained in step S2. Here, when the image size is A1 size, the roll film is cut in the long side size, and when the image size is A2 size, the roll film is cut in the short side size.

In step S6, the photosensitive film F cut from the roll film is mounted on the arrangement surface of the recording drum 11 by the tip pressing plate 13 and vacuum suction. At this time, since the punch units P2 and P3 are retracted from the arrangement surface of the recording drum 11, the die unit 20 does not interfere with the mounting of the photosensitive film F. In step S7, the die unit 20 is returned from the retracted position to the punch position by the die motors 45P2 and 45P3. In step S8, the recording drum 11 is rotated and the exposure head 1 is rotated.
An image is recorded on the photosensitive film F by exposing the photosensitive film F with the LED light modulated according to the image data while moving 4 in the axial direction of the recording drum 11.

When the image exposure is completed, in step S9,
It is determined whether the automatic mode is set as the processing mode. If the automatic mode is set, the process proceeds to step S10. In step S10, it is determined whether the image has a large size, that is, A1 size. When the image is of A1 size, the process proceeds from step S10 to step S11, and the punch units P1 to P3 are sequentially operated P1.

When it is determined that the "circumferential direction" is set, the process proceeds to step S11. In step S14, "N
If it is determined to be "o", the process proceeds to step S15.
In step S15, it is determined whether or not "axial direction" is set as the punch hole arrangement direction. When it is determined that the "axial direction" is set, the process proceeds to step S16. Also, when the automatic mode is set,
Also when it is determined in step S10 that the image is not in A1 size (A2 size), the process proceeds to step S16. In step S16, a P1 and P4 operation process for simultaneously operating the punch units P1 and P4, that is, a process for forming a plurality of punch holes in the axial direction of the recording drum 11 is executed (described later). If it is determined "No" in step S15, the process proceeds to step S17. In step S17, the punch units P1 to P4 are sequentially operated P1 to P1.
The P4 operation process, that is, the process of making a plurality of punch holes in the circumferential direction and the axial direction of the recording drum 11 is executed (described later).

When the punching process of step S11, S16 or S17 is completed, the process proceeds to step S12, and the die unit 20 is retracted from the punch position to the retracted position by the die motors 45P2 and 45P3. In step S13, the discharged photosensitive film F is discharged by the discharge mechanism 16,
The process returns to step S3 to wait for the next exposure start command for the photosensitive film F.

Here, since the die unit 20 of the punch units P2 and P3 can be retracted from the arrangement surface of the photosensitive film F by the retracting mechanism 29, when the photosensitive film F is mounted or ejected, the die unit 20 is exposed. Since it does not get caught on F, it is easy to mount and discharge the photosensitive film F. In the P1 to P3 operation processing in step S11,
In step S21 of FIG. 10, the recording drum 11 starts to rotate at a low speed which is considerably slower than the rotational speed during image recording. In step S22, the elapse of time T1 is awaited. This time T1 is the time from when the recording drum 11 starts rotating to when the punch unit P1 reaches the vicinity of the position facing the punch residue collection box 43 arranged below the recording drum 11.

25, the punch solenoid 35P2 is driven to operate the punch unit P2. As a result, a punch hole is formed in the central portion of the photosensitive film F on the front side in FIG. Further, the generated punch residue falls down and is collected in the punch residue collection box 43.

In step S26, the elapse of time T3 is awaited. This time T3 is the time from the operation of the punch unit P2 until the punch unit P3 reaches the vicinity of the position facing the punch residue collection box 43 arranged below the recording drum 11. When time T3 has elapsed, step S
27, the punch solenoid 35P3 is driven to operate the punch unit P3. As a result, punch holes are punched in the rear end portion of the photosensitive film F on the front side in FIG. 3, and three punch holes are punched in the photosensitive film F along the circumferential direction of the recording drum 11 on the front side in FIG. Further, the generated punch residue falls down and is collected in the punch residue collection box 43. In step S28, the rotation of the recording drum 11 is stopped and the process returns to the main routine. In this way,
A plurality of punch holes are formed in the circumferential direction of the recording drum 11.

In the P1 and P4 operation processing of step S16, step S31 of FIG. 11 and step S2 of FIG.

Similarly to the operation of 33, the punch units P1 and P4 are operated. Therefore, two punch holes are formed in the photosensitive film F along the axial direction of the recording drum 11. Further, the generated punch residue falls down and is collected in the punch residue collection box 43. The operations of steps S44 to S48 operate the punch units P2 and P3 in the same manner as the operations of steps S24 to S28 of FIG. Therefore, two punch holes are formed in the photosensitive film F along the circumferential direction of the recording drum 11. As a result, two punch holes are formed along the axial direction and three punch holes are formed along the circumferential direction. The punch holes formed by the punch unit P1 at the front end in FIG. 3 of the photosensitive film F are common to the axial direction and the circumferential direction.

Regarding the shape of the punch holes formed by the punch units P1 to P4, for example, the punch unit P1 which is common in the axial direction and the circumferential direction has a perfect circle, and the punch units P2 and P3 have a long length in the circumferential direction. In the circle and punch unit P4, it is an ellipse that is long in the axial direction. here,
The processing mode can be switched between an automatic mode and a manual mode. When the automatic mode is set, a plurality of punch holes are automatically formed on the long side of the photosensitive film F according to the image size. In addition, when the manual mode is set, a plurality of punch holes are punched in any of the axial direction and the circumferential direction or both directions regardless of the image size.

Further, since the punch residue collecting box 43 is arranged below the recording drum 11 and the punching operation is performed when the punch residue collecting box 43 is arranged to face the punch residue collecting box 43, the punch residue is easily collected without being scattered in the apparatus. it can. Further, since it is not necessary to stop the recording drum 11 during punch processing, the punch processing time is shortened.
