Description

Detailed Description of the Invention 3. Detailed Description of the Invention [Field of Industrial Application] The present invention relates to an image recording apparatus that exposes an image to a photosensitive material and transfers the image to an image-receiving material after development.

[Prior Art] As an image recording device for obtaining a color image using a heat-developable photosensitive material, as shown in JP-A-59-75247, an image is exposed on the heat-developable photosensitive material in an exposure section and then developed in a developing section. However, a method is known in which the image after thermal development is transferred to image receiving paper.

In this image recording device, the photosensitive material taken out is exposed to light in an exposure section located below, is sent laterally to the exposure section to be subjected to heat development, and is then sent laterally to receive the image. It comes into close contact with the material and is transferred.

As described above, in the conventional image recording apparatus, each component is arranged side by side, which causes an increase in the installation space. Furthermore, since the image-receiving material after transfer is discharged laterally, the tray for taking out the image-receiving material further increases the installation area.

In consideration of the above facts, the present invention aims to provide an image recording apparatus which can reduce the floor area of the apparatus and which allows the image receiving material f4 to be moved over the top of the apparatus.

[Summary and operation of the invention]

In the image recording apparatus according to the present invention, the development transfer section is disposed above the exposure section, and the image receiving material take-out section is further disposed above the development transfer section.

Therefore, in the present invention, when the photosensitive material is sent to the exposure section and exposed by the exposure head, this photosensitive material is sent to the development and transfer section above it and is brought into close contact with the image receiving material, where development and transfer are performed. After transfer, the image-bearing material is removed to the top of the device.

In the present invention, when the exposed photosensitive material is sent to the development and transfer section, it is reversed and sent to the development and transfer section, thereby making it possible to further reduce the size of the apparatus.

In this development and transfer section, development and transfer may be performed using the same heating source, or heating means for the development section and transfer section may be provided separately.

The image recording apparatus of the present invention may have a structure in which an image-forming solvent such as water is applied to a photosensitive material or an image-receiving material, and then transfer is performed to obtain an image on the image-receiving material. The structure may be such that an image is formed on the image-receiving material without using a forming solvent.

6 causes the drive roller 140 to come into contact with the outer periphery of the rotary drum 6 and apply braking to the rotary drum 16, and then the motor 78 rotates in the reverse direction, rotating the rotary drum 16 at a low speed in the direction opposite to the direction of the arrow.

At the same time, the solenoid 138 is actuated and the IIM arm 136 is inserted into the notch 134 of the rotating drum 16. Here, the rotating drum 16 is rotated again at a low speed by the driving roller 140, whereby the photosensitive material 14 wound around the outer periphery of the rotating drum 16 is transferred from the rear end to the peeling arm 1.
36, the winding direction is opposite to the direction of winding around the rotating drum 16. TI is released, and the solenoid 138 is now demagnetized and removed from the drum groove. The photosensitive material 14 is guided by a peeling guide 170 and inserted between conveyance rollers 172 and 174.

The tip of the peeled photosensitive material 14 is the rear edge detection sensor 17.
1, the motor 78 rotates at high speed until the ff1l+ peeled edge of the photosensitive material 14 reaches just before the water application section 20, and the notch 122 that accommodated the peeled rear edge of the photosensitive material 14 corresponds to the drive roller 140. The motor 78 is stopped, the solenoid 112 fixes the bin 104 with the positioning member 106, and the solenoid 146 is turned on.
40 away from the drum.

When the photosensitive material 14 is completely separated from the outer periphery of the rotating drum I6 by T1, the vacuum pump 96 is stopped.

On the other hand, the rear end detection sensor 171 detects the distance between the cup and the guide 170.
When the tail end of the photosensitive material 14 passing through is detected, the rotation of the pulse motor 78 is reduced to a low speed, and the photosensitive material 14 is fed through the water application section 20 at a relatively low speed.

At the same time, the motor 196 operates and the application roller 190
Then, the motor 228 rotates, and after a predetermined time delay, the clutch 3
30 join.

For this reason, water 192 is applied to the exposed surface of the photosensitive material 14 sent to the water application section 20 by the application roller 190.
The heat roller 340.3 of the development transfer section 22 is lifted upward by the guide plate 216 and the conveyor belt 226.
Sent to 42.

When the photosensitive material 14 is sent to the development transfer section 22, the image receiving material 2 is transferred to the image receiving material 2 by the conveying rollers 324 and 326 rotated by the clutch 330 which is engaged after a predetermined time delay.
6 is also sent to the development transfer section 22, where the photosensitive material 14 and the image receiving material 26 are brought into close contact and sandwiched. After that, motor 1
96 and motor 228 are stopped.

In the development transfer section 22, each heat roller is heated by the heater 358, so the photosensitive material I4 is thermally developed.
The developed image is transferred to the image receiver 26. Since water has already been applied to the exposed surface of the photosensitive material 14, reliable transfer is performed.

When the tip/end of the photosensitive material 14 sent out from the development transfer section 22 is detected by the tip detection sensor 378, the solenoid 3
84 causes the roller 380 to come into close contact with the conveying roller 376, thereby displacing the photosensitive material 14 downward.
It is held and conveyed by the winding wire 388 and the winding wire 390, sent out downward, and housed in the deodorizing box 32.

Further, both ends in the width direction of the image receiving material 26 which are set back from the leading end of the photosensitive material 14 are connected to a conveyor belt 398 and a conveyor roller 3.
74 and lifted up, dried by the heater 36, and then taken out to the takeout tray 3. For this reason, the image-receiving material 2G taken out to the take-out tray 38 has already been dried, and even when this image is picked up and viewed, lη deviation will not occur.

Note that after the leading end detection sensor 378 detects the rear end of the photosensitive material 14, the main switch is shut off to reduce the power consumption, and the display section becomes a standby display so that it can respond to the start signal of the next start switch.

Although the above-described embodiment shows a configuration in which the photosensitive material 14 is coated with water to improve the transfer efficiency, the present invention may also be configured such that the image-receiving material 26 is coated with water.

Further, the present invention may be of a configuration in which water application is not performed.

〔Effect of the invention〕

As explained above, the present invention has the advantageous effect that the development transfer section is disposed above the exposure section and the image receiving paper take-out section is further disposed above the exposure section, so that the arrangement space is reduced and the apparatus becomes compact.
