Abstract

PURPOSE:To adjust the precedent width of a photosensitive material when the photosensitive material and an image receiving material are put one over the other by varying the operation timing of at least either of a photosensitive material conveying means and an image receiving material conveying means. CONSTITUTION:A control means inputs the detection signal of a photosensitive material detection sensor 50 to control the operation of the image receiving paper conveying means such as conveyor rollers 62 and 64 and the operation of the photosensitive material conveying means such as a heat drum 42, a conveyor roller 46. Further, an operation timing setting means sets and varies the operation timing of the photosensitive material conveying means and image receiving paper conveying means optionally and outputs it to a controller. Therefore, the conveyance speed of the photosensitive material S and the conveyance start timing and conveying speed of image receiving paper C which is registered and stopped by the conveyor roller 62 can be varied. Consequently, the precedent width is corrected to a prescribed value.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an image recording apparatus that overlaps a photosensitive material and an image-receiving material and transfers image information on the photosensitive material to the image-receiving material under pressure.

[Conventional technology]

As an example of an image recording material using microcapsules encapsulating a photosensitive composition, for example, Japanese Patent Application Laid-Open No. 57-17983
A vinyl compound on a support, as disclosed in Publication No. 6,
Systems are known that carry synthetic polymeric resin-walled capsules containing a photopolymerization initiator and a colorant precursor. The image recording method using this system is to imagewise harden the microcapsules by exposure to light, rupture the unhardened microcapsules by applying pressure, and obtain a color image from the released colorant precursor. The method has the advantage of producing high quality images through simple dry processing. However, this system has the drawback of significantly lower photosensitivity than systems using silver halide.

A new recording material that improves these drawbacks, has high photosensitivity, and can obtain high-quality images through simple dry processing is disclosed in Japanese Patent Application Laid-Open No. 1983-1992 filed by the present applicant.
It is disclosed in Japanese Patent No. 275742. This recording material is a photosensitive and pressure-sensitive thermal development material, in which at least a photosensitive silver halide, a reducing agent, a polymerizable compound, and a color image forming substance are coated on a support, and at least the polymerizable compound and the color image forming substance are coated on a support. The color imaging material consists of a photosensitive composition encapsulated in identical microcapsules.

Regarding the image recording method of recording an image using this photosensitive pressure sensitive heat development material, please refer to Japanese Patent Application Laid-open No. 6
It is disclosed in Japanese Patent No. 1-278849. This image recording method first performs imagewise exposure to form a latent image, then develops it by heating, and polymerizes the polymerizable compound in the area where the latent image exists to form a macromolecular compound to form microcapsules. harden. Then, the image-receiving material having an image-receiving layer to which the color image-forming substance can be transferred is stacked and pressurized to rupture at least a portion of the microcapsules in the area where the latent image does not exist, and the color image-forming substance is transferred to the image-receiving material. to obtain an image on an image-receiving material.

Then, using the above-mentioned photosensitive material, this photosensitive material is subjected to imagewise exposure, heat development is performed, and then the image recording material is overlaid with an image-receiving material and pressed, and an image is obtained on the image-receiving material by transfer, which is automatically performed. As for the device, for example, the patent application filed in 1982 by the present applicant is applicable. -51896.

[Problem that the invention seeks to solve]

To overlap a photosensitive material and an image-receiving material, for example, the image-receiving material is placed on standby upstream of the overlapping part, the photosensitive material is detected by a sensor upstream of the overlapping part, and after a predetermined period of time has elapsed, transport of the image-receiving material is started. The photosensitive material and the image-receiving material are conveyed so as to reach the overlapping portion almost simultaneously. The superimposed photosensitive material and image-receiving material are peeled off after the image information on the photosensitive material is transferred to the image-receiving material by applying pressure. This is done by inserting a peeling claw between the materials. The photosensitive material is superimposed slightly ahead of the image-receiving material so that the peeling claw can easily enter between the two materials, and the peeling claw swings so as to flip up only the photosensitive material during peeling. Therefore, the leading width of the photosensitive material needs to be set accurately, but due to placement errors of the photosensitive material detection sensor upstream of the overlapping part, operational response errors of the image receiving material conveying means, etc., the leading width of the photosensitive material may be set to the allowable setting value. If it deviates from this, the peeling claw will not work properly and reliable peeling will not be performed, resulting in a jam.

Moreover, the image information on the photosensitive material will not be transferred to the proper position on the image-receiving material.

Therefore, the purpose of the present invention is to solve the above problems,
It is an object of the present invention to provide an image recording device that guarantees an accurate lead width of a photosensitive material to an image receiving material and performs reliable peeling and transfer.

[Means for solving problems]

The above-mentioned object of the present invention is to provide an image recording apparatus that overlaps a photosensitive material and an image-receiving material and transfers image information on the photosensitive material to the image-receiving material under pressure, and detects the photosensitive material upstream of the overlapping part. A sensor, a control means for controlling the operation of at least one of a photosensitive material and an image-receiving material conveyance means based on a signal from the sensor, and a setting means for setting the operation timing of the conveyance means by the control means. This is achieved by an image recording device characterized by the following.

In other words, even if the leading width of the photosensitive material deviates from the allowable setting value when the photosensitive material and the image receiving material are overlapped due to placement errors of the photosensitive material detection sensor, operational response errors of the image receiving material conveying means, etc., the photosensitive material cannot be conveyed. By arbitrarily setting and changing the operation control element of the control means for controlling the operation of at least one of the means and the image-receiving material conveying means,
The leading width can be corrected to a predetermined value.

To correct the leading width of the photosensitive material, for example, the photosensitive material transport speed, image receiving material transport speed, and operation start timing of the image receiving material transport means are controlled.

Note that setting the control elements requires specialized knowledge, so a configuration in which the settings can be made by simultaneously operating a plurality of specific keys of the image recording device operation keys is preferable.

Desirable light-sensitive materials include those having on a support a substance on which an image formed by imagewise exposure is fixed by pressure.

In the present invention, the photosensitive material refers to a material for obtaining a visible image by applying pressure to a latent image generated by imagewise exposure.

Further, the present invention can be applied to both a system in which the exposed portion is polymerized and hardened, and a system in which the exposed portion is depolymerized and softened.

However, for ease of understanding, the following explanation will proceed using a photopolymerizable type as an example.

In this case, it may include a step of preliminary heat development or wet development before applying pressure.

An example of such a material is a type in which a polymerizable compound is imagewise cured by imagewise exposure and then a visible image is obtained by applying pressure. The material disclosed in Japanese Patent No. 179836 is mentioned. This material has a synthetic polymer resin wall capsule containing a vinyl compound, a photopolymerization initiator, and a colorant precursor supported on a support.

Alternatively, after containing silver halide and giving imagewise exposure, heat development is performed to develop the silver halide, the polymerizable compound is simultaneously cured in correspondence with this development, and then pressure is applied to form a visible image. An example of the material that can be obtained is the material disclosed in Japanese Unexamined Patent Publication No. 61-275742 filed by the present applicant.

The material disclosed in JP-A No. 61-275742 is one in which a color image-forming substance is transferred to an image-receiving material having an image-receiving layer after thermal development to obtain an image on the image-receiving material. at least a photosensitive silver halide, a reducing agent,
Coated with a polymerizable compound and a color image-forming substance,
At least the polymerizable compound and the color image forming substance are encapsulated in the same microcapsule.

In addition, when the image recording apparatus of the present invention uses a photosensitive material of the type that performs heat development before applying pressure to fix the image, it means one that has a heat development device, and a type that does not perform heat development. When using one, it means one that does not have a heat developing device.

FIG. 2 is a block diagram of control for overlapping the photosensitive material S and the image receiving paper C. The control means controls the transport roller 6 by inputting the detection signal of the photosensitive material detection sensor 50.
It controls the operation of one stage of image-receiving paper conveyor 13 such as 2 and 64, and photosensitive material conveyance means such as heating drum 42 and conveyance roller 46. Further, the operation timing setting means arbitrarily changes the operation timing of the photosensitive material conveyance means and the image receiving paper conveyance means and outputs the changed settings to the control device, so that the conveyance speed of the photosensitive material S and the conveyance roller 62 are registered and stopped. The transport start timing and transport speed of the image receiving paper C can be changed. To change the operating timing, for example, manually enter a correction value from the numeric keypad of the image recording device, and change the set value stored in the control means. The control means then controls the operations of the photosensitive material transport means and the receiving paper transport means based on the changed timing setting values.

Note that the set values are stored in a read/write memory backed up by a battery, and the stored contents are preserved even if the power to the device is turned off.

FIG. 3 is a timing chart for controlling the operation of the photosensitive material conveying means and the receiving paper conveying means. The tip of the photosensitive material S being conveyed while being heated by the heat developing device 40 is the sensor 5.
0, and after a predetermined time T has elapsed, the stopped conveyance rollers 62 and 64 are driven to rotate, and conveyance of the image-receiving paper C is started. That is, the control means controls the conveyance of the image receiving paper C (7) based on the photosensitive material detection signal of the sensor 50 and the time T stored in advance. Time T is the time from when the leading edge of the photosensitive material S is detected by the sensor 50 until the conveyance of the image receiving paper C is started.The image receiving paper C is conveyed in synchronization with the conveyance of the photosensitive material The photosensitive material S is applied to the receiving paper C at a nip portion of
They are superimposed in advance. The operation timing setting means is for changing the above-mentioned time T, and in order to change the time T, it is sufficient to change the timing for starting conveyance of the receiving paper. For example, when the leading width of the photosensitive material S is larger than a set value, the time T is shortened, and when the leading width is smaller than the set value, the time T is lengthened.

Furthermore, without changing the time T, the photosensitive material conveying speed or the image receiving material conveying speed may be changed.

To measure the leading width of the photosensitive material S, it is sufficient to take out the superimposed photosensitive material S and image receiving paper C without operating the peeling claw. Then, by directly inputting the difference between the set value and the measured value or the measured value using the numeric keypad, the operation timing of the conveyance means is automatically changed. Further, when the conveyance rollers 62 and 64 that convey the image receiving paper C are driven by a pulse motor, an input may be made to change the set number of pulses.

It is hardly necessary to correct the leading width of the photosensitive material S during normal use of the image recording apparatus, and it is sufficient to perform it when assembling the image recording apparatus. It is also necessary to make corrections if a malfunction occurs during use, but since these are done by people with specialized knowledge, it is important to keep the operation keys on the operating keys to prevent general users from making corrections by mistake. Preferably, the configuration is such that correction can be performed in engineer mode by simultaneously operating a plurality of specific keys.

Furthermore, in the engineer mode, it is possible to select a color correction method according to the coloring characteristics of the photosensitive material S.

To perform color correction, for example, test recording is performed under standard conditions, the color tone of the resulting recording is measured with a sensor, and based on this measurement result, the amount of color correction is calculated to improve the gray balance. There is a method of automatically changing the color correction means, and a method of manually or automatically inputting coloring characteristic information such as the emulsion number displayed on the photosensitive material magazine 14 to the color correction control means and operating the color correction means.

In the former method, color correction is performed based on the obtained recorded matter, so that gray balance can be corrected favorably, but the photosensitive material S is consumed for each correction. Further, although the latter method does not consume the photosensitive material S during correction, it cannot compensate for changes in coloring characteristics over time. However, depending on the type of recording, only one of the corrections is sufficient, so in this case it is preferable to set the correction method to one of the two in the engineer mode. To change the correction method, a new correction method may be set in engineer mode by simultaneously operating a plurality of specific keys of the image recording device operation keys. By specifying the color correction method, correction according to the type of recording can be performed reliably, and by changing the color correction method, it is possible to handle color correction for different types of recording.

〔Effect of the invention〕

According to the present invention, by changing the operating timing of at least one of the photosensitive material conveying means and the image receiving material conveying means, even if there is a placement error of the photosensitive material detection sensor or an error in the operation response of both conveying means, the photosensitive material It is possible to adjust the leading width of the photosensitive material when the material and the image-receiving material are overlapped.

By accurately setting the leading width of the photosensitive material to a predetermined value, the image information on the photosensitive material is pressure-transferred to the image-receiving material.
Both materials can be reliably separated. Furthermore, the image information on the photosensitive material can be transferred to an appropriate position on the image-receiving material, and a good recorded matter can be obtained.
