Abstract

PURPOSE:To easily operate an image recorder again after jamming is released when abnormality occurs outside a feeding part by judging whether a recording material being fed is long enough to be carried, cutting the recording material into the shortest length which can be carried and stopping operation. CONSTITUTION:When jamming occurs outside an exposing part, a photosensitive material detects whether it is currently exposed or not at the time when jamming occurs. If so, it is detected whether the photosensitive material S is cut or not. When it isn't cut yet, it is detected whether the photosensitive material is long enough to be carried or not. When the photosensitive material S is long enough to be carried, the photosensitive material S is cut at the same time when detecting is performed so as to stop the operation of the image recorder. When the photosensitive material S isn't long enough to be carried, a motor driving circuit is supplied with an operation signal. While the photosensitive material S is fed, the number of pulses is counted in response to the shortest length of the photosensitive material S which can be carried. After that, supply of the operation signal to the motor driving circuit is stopped and the photosensitive material S is cut so as to stop the operation of the image recorder. Thus, jam processing and operation start after jam processing are facilitated.

[Problem to be solved by the invention]

In an image recording method that uses a roll of photosensitive material and cuts the photosensitive material while exposing it to light, the image recording device is configured to immediately stop operation when an abnormality such as a jam occurs, for example. . However, if the operation of the image recording apparatus is stopped during exposure and before cutting the photosensitive material, the photosensitive material that was being exposed cannot be reused when operation is restarted, and must be cut and removed. This requires a configuration that exposes the photosensitive material transport path, and furthermore, it is not easy to reset the photosensitive material.

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned problems, and to provide an image recording method that allows the image recording apparatus to be easily restarted after a jam is cleared.

[Means and effects for solving the problem] The above object of the present invention is to provide an image recording method for obtaining an image on a recording material by feeding out and cutting a recording material wound into a roll, in which the recording material is cut outside the feeding section. This is achieved by an image recording method characterized in that, when an abnormality occurs, it is determined whether the recording material being fed out has a length that can be conveyed, the recording material is cut to at least the minimum length that can be conveyed, and the operation is stopped.

That is, when a jam occurs outside the feeder, it is determined whether the recording material has a length that can be conveyed to the outside of the image recording apparatus, and if the length is not reached, the recording material is fed to at least the minimum length that can be conveyed. By cutting the recording material, the cut recording material can be discharged from the apparatus prior to recording when the image recording apparatus is restarted, without exposing the recording material conveyance path of the feeding section.

In the present invention, the recording material may be any material as long as it is wound into a roll.

Examples of recording materials include so-called photothermographic materials in which an image obtained by thermal development is transferred to an image-receiving material by heating.

This heat-developable photosensitive material is one in which a mobile dye is released in an image-like manner by heating, and the mobile dye is transferred to an image-receiving material (dye-fixing material) having a mordant using a solvent such as water. , transfer to the image receiving material is performed using a high boiling point organic solvent, transfer is performed to the image receiving material using a hydrophilic thermal solvent contained in the image receiving material, or the mobile dye is thermally diffusible or sublimable, Those that transfer to dye-receiving materials such as supports are known, and specifically, U.S. Pat. Nos. 4,463,079 and 4.474.

It is transported to the exposure section by a pair of transport rollers 12, and is cut into a predetermined length by a cutter 18 while being exposed by an exposure device 6 between a pair of transport rollers 14 and 16.

The photosensitive material S, on which a latent image has been formed by the exposure device 6 and cut into a predetermined length, is conveyed to a heating and developing device 30 by a pair of conveying rollers 20 .

The heat developing device 30 includes a hollow cylindrical heating drum 34 , four belt support rollers 36 , and a heating drum 3 that is stretched around the belt support rollers 36 in a heat insulating housing 32 .
Endless belt 3 wrapped around the circumferential surface of 4 at an angle of approximately 240°
8, the photosensitive material S is transferred to the belt 38 and the heating drum 34.
The sample is conveyed while being held between the heating drum 34 and heated at about 150° C. by a /% rogen lamp 40 provided in the heating drum 34.

A fan 50 is disposed near the heat developing device 30 to exhaust the atmosphere of the heat developing device 30 to the outside of the housing 2.
The high temperature atmosphere around the heat developing device 30 is exhausted to prevent the image recording device from becoming too hot.

The photosensitive material S heat-developed by the heat-developing device 30 is
It is conveyed to the overlapping device 60. On the other hand, the image receiving paper C is supplied from the image receiving paper cassette 70 by the image receiving paper supply roller 74 or the image receiving paper C is supplied from the manual feed tray 72.
is conveyed to the overlapping device 60 by a pair of conveying rollers 76. The photosensitive material S and the image-receiving paper C are then overlapped at the overlapping portion and conveyed to the pressure transfer device 80 by the pair of conveying rollers 62. Here, the photosensitive material S is superimposed on the image receiving paper C approximately 1,501 times in advance.

The pressure transfer device 80 includes a pair of pressure rollers 82 that come into pressure contact with each other, and a backup roller 84 for equalizing the axial pressure exerted by the pressure rollers 82, and transfers the superimposed photosensitive material S and image receiving paper C. Approximately 500 kg/while being transported in a pinched manner

By pressing the superimposed photosensitive material S and image receiving paper C, the image on the photosensitive material S is transferred to the image receiving paper C and the image develops color. Further, the pressure transfer device 80 is configured to transfer the photosensitive material S and the image receiving paper C so that wrinkles do not occur when the photosensitive material S and the image receiving paper C are sandwiched between the pressure rollers 82.
A blade 86 is provided that urges one pressure roller 82.

Further, the pressure transfer device 80 includes a wrap prevention member 88 that comes into contact with the pressure roller 82 in order to prevent the photosensitive material S and the image receiving paper C from wrapping and adhering to the pressure roller 82 after being pressed.

Figure 2 is a flowchart of control when a jam occurs;
FIG. 3 is a block diagram for performing this control, in which the CPU controls the motor drive circuit, cutter drive circuit, and jam display device by signals supplied from the jam detection circuit, motor pulse count circuit, and sensor. Wholesale.

Inside the image recording apparatus, sensors s'vv1. ~ SW8 is arranged, and the occurrence of a jam is detected by detecting whether or not the photosensitive material S and image receiving paper C being conveyed pass between the respective sensors within a set time.

When the jam detection circuit detects the occurrence of a jam within the image recording apparatus, it first detects where the jam has occurred. That is, the jam occurrence portion is detected based on the ON/OFF status of the sensors SWI to sw8. When a jam occurs in the exposure section, the gap is cut off as soon as it is detected, and the operation of the image recording apparatus is stopped. Here, the jam occurrence display device is supplied with an activation signal from the CPU, and displays the occurrence of a jam in the exposure section. Next, the operator exposes the photosensitive material conveyance path in the exposure section and removes the photosensitive material S to clear the jam. At this time, since the photosensitive material S has been properly cut, the photosensitive material can be easily resected after the jam is cleared.

Next, when a jam occurs in a region other than the exposure section, it is detected whether or not exposure is being performed when the jam occurs. Since the photosensitive material S is stopped at a predetermined position during non-exposure, the operation of the image recording apparatus is immediately stopped when it is detected that the photosensitive material S is not being exposed. If exposure is in progress, then it is detected whether or not the photosensitive material S is before cutting. After cutting, since the photosensitive material S has stopped at a predetermined position, the operation of the image recording apparatus is immediately stopped. If it is before cutting, then it is detected whether the length of the photosensitive material S being drawn downstream from the cutter is such that it can be transported. If the length of the photosensitive material S is such that it can be transported, the photosensitive material S is cut at the same time as the detection, and the operation of the image recording apparatus is stopped. Furthermore, when the length of the photosensitive material S is less than the length that can be conveyed, an activation signal is supplied to the motor drive circuit, and while the photosensitive material S is being fed out, the number of pulses supplied to the motor is counted by the motor pulse count circuit, and the number of pulses supplied to the motor is counted. When the number of pulses corresponding to the minimum transportable length of the material S is counted, the supply of an operating signal to the motor drive circuit is stopped, the photosensitive material S is cut, and the operation of the image recording apparatus is stopped.

When a jam occurs in a region other than the exposed section, the operation of the image recording device is stopped as described above, so the jam can be cleared by exposing only the conveyance path in the jammed section, and the conveyance path in the exposed section can be cleared. It is possible to clear the jam without having to do so. In addition, since the cut photosensitive material S in the exposure section has a length that can be transported, there is no need to expose the transport path in the exposure section and take out the cut photosensitive material S, and when the image recording device restarts operation, The cut photosensitive material S can be discharged by a so-called initial operation in which the conveying device is idled. Therefore, even if the cut photosensitive material S remains in the exposed area, there is no need to indicate a jam in the exposed area.

Alternatively, the cut photosensitive material S may not be ejected in the initial operation at the exposure section, but may be forcibly ejected immediately after cutting to stop the operation of the image recording device. Therefore, the ejection path is provided separately from the conveyance path during image recording.

Note that the method of the present invention is not limited to the embodiments described above, and can also be applied to copying machines, laser printers, etc. that use recording materials wound into rolls.

〔Effect of the invention〕

According to the present invention, when a jam occurs at a location other than the feeding section,
A jam can be cleared without exposing the recording material conveyance path in the feeding section, and the recording material cut in the feeding section can be ejected forcibly or by the initial operation at the start of operation after clearing the jam. . Therefore, in the event of a jam in a part other than the feeding part, even if cut unnecessary recording material remains in the feeding part, there is no need to display the jam in the feeding part, and the image recording device can clear the jam and start operation after the jam is cleared. becomes easier.
