Description

  The present invention relates to an image recording apparatus for feeding a silver salt photosensitive material to a drum, winding it around the outer surface of the drum and adsorbing it, exposing the silver salt photosensitive material while rotating the drum, and recording an image.

  Conventionally, a cartridge is loaded into the apparatus, the photosensitive paper contained in the cartridge is pulled out and fed, and the photosensitive paper is wound around the drum outer surface and held by vacuum suction inside the drum while rotating the drum. An image recording apparatus is known in which a photosensitive paper held on the outer surface of a drum is peeled off by a peeling member after being recorded on the drum and conveyed to the next process for development (for example, Patent Documents 1 and 2 below). reference).

  When a cartridge is mounted on such an image recording apparatus, it is necessary to pull out the leading end portion of the photosensitive paper from the cartridge in order to feed the photosensitive paper into the apparatus. This drawn portion is exposed to external light and exposed to light. Wake up. Further, if the unused state continues while being pulled out for a relatively long time in the apparatus, the pulled-out portion is more exposed to light by external light than the photosensitive paper inside the cartridge. Such a light-covered portion of the photosensitive paper is likely to cause a substantial deterioration of the image quality after development and at the same time to cause a deterioration of the developing solution itself.

In the conventional image recording apparatus, regardless of the state of the photosensitive paper, the photosensitive paper fed to the drum is always wound around the drum, and then peeled and discharged. However, as described above, unnecessary portions of the photosensitive paper that are covered with external light are always wound around the drum, so that the winding time is wasted. In addition, an error such as a jam is easily caused when the photosensitive paper is peeled off, and this tends to hinder stable image recording.

  A case where the peeling member and the accumulating guide member of the image recording apparatus shown in FIGS. 1 to 4 are controlled to convey the photosensitive paper and a case where an unnecessary portion of the photosensitive paper is discarded will be described with reference to FIG. FIG. 5A is a diagram illustrating a case where the normal exposed photosensitive paper is conveyed downstream for development, and FIG. 5B is a diagram illustrating a case where an unnecessary portion of the photosensitive paper is discarded in the discarding unit.

  As shown in FIG. 5A, the photosensitive paper S after the normal exposure is performed on the drum 10 based on the halftone image data, the peeling member 15 is rotated to the peeling position by the motor M4, and the accumulating guide member. In the state where 18 is rotated to the guide position by the motor M5, it is peeled from the drum 10 by the peeling member 15, transported by the drum 10 and the driven roller 31 while being guided by the accumulating guide member 18, and transported by the motor M6. It is further conveyed downstream by the roller pair 32.

  On the other hand, when an unnecessary portion S1 such as a tip portion exposed to external light and causing light covering is sent to the drum 10 when the cartridge 13 is loaded into the loading portions 12 and 12 ', the suction blower P1 is activated. Unnecessary portion S1 is not wound around the drum 10 and is not attracted thereto, and as shown in FIG. 5B, the peeling member 15 is rotated to the peeling position by the motor M4 and the accumulation guide member 18 is accumulated by the motor M5. In this state, the drum 10 and the driven roller 31 are transported and fall to the disposal unit 61 by their own weight.

  Next, the operation of the image recording apparatus 1 of FIGS. 1 to 5 will be described with reference to the flowchart of FIG.

  First, when halftone image data transferred from an external RIP 49 is input (S01), the control unit 50 drives the feeding unit 14 and feeds photosensitive paper from the cartridge 13 in the loading unit 12 or 12 ′ (S02). ). At this time, whether or not the cartridge 13 is newly loaded is determined based on a detection signal from the detection sensors 12a and 12a '(S02). If the cartridge 13 is newly loaded, the conveyance amount of the photosensitive paper is determined. Is measured by the rotary encoder E1, and the leading end S1 (FIG. 5B) of the photosensitive paper is cut to a predetermined length by the cutter unit 10a (S04).

  Then, the operation of the suction blower P1 is stopped (S05), and the peeling member 15 is moved to the peeling position as shown in FIG. And the accumulating guide member 18 is moved to the accumulating position (S06), and the drum 10 is rotated and the tip S1 is transported to and from the driven roller 31 to be dropped to the disposal unit 61 by its own weight ( S08).

  As described above, when the cartridge 13 is loaded in the loading section 12 or 12 'with the photosensitive paper pulled out, even if the leading end S1 is exposed and light exposure occurs, it is immediately after the cartridge 13 is newly loaded. It is possible to detect the conveyance and automatically discard the tip end portion S1. In addition, since the tip portion S1 is discarded without being wound around the drum 10, the disposal process can be performed quickly.

  Next, the photosensitive paper with the leading end cut out is further pulled out, and the portion not affected by light cover is transported by the feeding unit 14 and fed to the drum 10 (S09). The photosensitive paper S is attracted to the drum and the drum is rotated. On the other hand, image recording is performed by exposure based on the image data inputted with the light beam from the optical unit 16 (S10).

  Next, as shown in FIG. 5A, the photosensitive paper exposed by exposure is peeled off from the drum 10 by the peeling member 15 at the peeling position, and guided to the outlet 19 by the conveying roller pair 32 and the like while being guided by the accumulating guide member 18. (S11), sent from the connecting portion 19a to the developing unit 21, and after developing the photosensitive paper (S12), it is discharged to the discharge portion 28 (S13). If the next image data has been input (S14), the process returns to step S02.

  As described above, according to the image recording apparatus shown in FIGS. 1 to 6, the unnecessary tip S <b> 1 generated by light exposure of external light on the photosensitive paper when the cartridge 13 is loaded into the apparatus is not wound around the drum 10. Since the disposal process is performed on the disposal unit 61 inside the apparatus, the unnecessary tip S1 can be quickly disposed of, and the operation of winding the unnecessary tip S1 around the drum 10 by suction is unnecessary, so that an error such as a jam occurs. Can be prevented and stable operation can be realized. Wrapping the photosensitive paper around the drum 10 means winding the photosensitive paper for approximately one circumference of the outer periphery of the drum 10 while adsorbing it to the drum 10, so that a predetermined time was required for winding, but in this embodiment, Since the unnecessary tip portion S1 can be disposed of without being wound around the drum 10, it can be disposed of quickly without taking extra time.

  Further, since the photosensitive paper that has been exposed to light can be disposed of at the position of the accumulating guide member 18 and does not need to be sent to the developing unit 21, there is no significant deterioration in image quality after development, and the developer itself in the developing unit 23 and the like is not deteriorated. Does not cause deterioration.

  As described above, in the present embodiment, since there is a high possibility that the front end portion S1 of the photosensitive paper pulled out when the cartridge 13 is loaded is covered with light, the front end portion S1 is automatically set to a predetermined length as an unnecessary portion. After being cut into pieces, the waste is disposed in the disposal unit 61 inside the apparatus. For example, when the exposure to the photosensitive paper is interrupted, unnecessary parts when the exposure to the photosensitive paper is interrupted are similarly wound after the winding of the drum 10 is stopped. It can be discarded in the internal discard unit 61.

  Further, when the leading edge S1 of the photosensitive paper is pulled out from the cartridge 13 and remains unused for a relatively long time, normal exposure is performed after executing the steps S04 to S08. Even if the leading edge portion S1 of the photosensitive paper is greatly affected by light exposure due to external light as compared with the photosensitive paper in the cartridge 13, the photosensitive paper to be exposed is not affected by light exposure.

  In the case of the above-described unused duration, the steps S04 to S08 can be automatically executed when the control unit 50 detects that the device has not been used for a predetermined time or longer by a timer provided in the apparatus. . Further, the steps S04 to S08 may be similarly executed according to information input by the user from the display input unit 2 of FIGS.

  As described above, the present invention has been described with reference to the embodiments. However, the present invention is not limited to these embodiments, and various modifications can be made within the scope of the technical idea of the present invention. For example, it goes without saying that the image recording apparatus according to the present invention can be applied to other than the creation of a color proof.
