There is something to record. In this case, the conventional procedure is to first create a mask original and then start an exposure process. However, this takes a long time to record the image, especially in the case of color image recording, as it requires creating multiple types of mask masters (usually three types: red, green, and blue) and exposing them to each other. There was a problem in that it took a long time to record images.

[Object of the invention] The present invention has been made in view of the above problems, and

Means for Solving Problem E] In order to achieve this object, the recording device of the present invention includes a light-transmitting film and a photosensitive recording medium disposed facing each other, and a photomask master plate is placed on the surface of the light-transmitting film. A mask master creating device is disposed so as to be movable in a fixed direction along the surface of the light-transmitting film, and the device is arranged to move freely in a fixed direction along the surface of the light-transmitting film, and the device is arranged to move the surface of the photosensitive recording medium through the original photomask created on the surface of the light-transmitting film. The gist of the present invention is that an exposure device such as a light source for exposure is arranged so as to be movable in the same direction simultaneously with the mask original production device.

[Function] According to the recording apparatus of the present invention having the above configuration, a light-shielding image is formed on the light-transmitting film surface, and the photosensitive recording medium is exposed to light through the mask master plate thus formed. proceed simultaneously. Therefore, the time required for image recording is significantly reduced.

[Example] Hereinafter, an example embodying the present invention will be described with reference to the drawings.

FIG. 1 shows an example in which the present invention is embodied in a color copying machine.

In this figure, a fluorescent lamp 11 serving as a light source is movably disposed in the center of the copying machine.

Below the fluorescent lamp 11, a condensing lens (not shown) and a filter 12 including a red filter 12a, a green filter 12b, and a blue filter 12G are disposed so as to be always movable relative to the fluorescent lamp 11. There is. Immediately below the filter 12, a heat-sensitive recording paper 6, which is a light-transmitting film, is stretched and fixed via long rod-shaped support members 4a, 4b and 5a, 5b, respectively, in the forward direction of the moving direction and in the dipping direction. It has become. The thermal recording paper 6 is a roll of paper that is unwound from 1 to an uncoiler on the left side of the figure and wound up into 2 pieces by a recoiler on the right side of the figure. The thermal recording paper 6 is fed by the paper feeding motor b. On the other hand, a thermal print head 1, which is a printing device, and a platen 3 are arranged to sandwich the thermal recording paper 6 so as to be movable back and forth in the direction of movement of the thermal recording paper 6. As shown in FIG. 2, in this printing device, a screw shaft 61.61 is installed parallel to the conveying direction' of the recording paper 6, and a lead 62.62 is screwed into the screw shaft 61.61. installed in between. Further, a fluorescent lamp 11 and a filter 12 are also movably mounted as one unit U together with the print head 1 and platen 3. A motor a is connected to one end of the screw shaft 61. on the other hand,
Photosensitive and pressure sensitive recording paper 21 is housed in a paper cassette 20, and is pulled out sheet by sheet and exposed to a light source 11 and a filter 12.
, and is guided to the part directly below where the thermal recording paper 6 is tied. A predetermined exposure is then performed at that position,
At the end of exposure, the light-sensitive and pressure-sensitive recording paper 21 is configured to pass through pressure fixing rollers 23, 24 and be ejected from the copying apparatus.

In this color copying machine, image data for each color of red (R), green (G), and blue (B) is input separately from a color original using an input device or reading mechanism, and copies are made based on this data. However, among the captured color image data, red (R> data) is first sent to the print head 1 via the data input section 7 and the control section 8, and is sent to the print head 1 between the print head 1 and the platen 3. Thermal recording paper 6 held in
Printing is done on the surface. In this embodiment, printing is performed by leaving the thermal recording paper 6 stationary and moving the line thermal head in the sub-scanning direction (the conveying direction of the thermal recording paper 6).

In this case, as shown in FIG. 3, when the position of the print head 1 serving as a printing device is detected by the photointerrupter 51, the control section 8 sets the initial position based on the signal from the photointerrupter 51. At the same time, a signal is sent to the solenoid 33 attached to the platen 3, and the platen 3, which had been released from the print head 1, is pressed against the print head 1 while sandwiching the thermal recording paper 6.

Next, the step motor a is rotationally driven by a signal from the driver circuit 10, and the unit U moves in the sub-scanning direction. At this time, as shown in FIGS. 3 and 4, one printing start position S is set in advance at a position a certain number of steps away from the initial position, and the color sent from the control unit 8 is Printing progresses as the print head 1 moves along the data print line in the direction of the arrow (rightward) from the print start position S. At the same time, the light source 11 lights up,
Since the exposure device consisting of the light source 11, filter 12, etc. moves integrally with the print head 1 etc., the 21 sides of the photosensitive and pressure sensitive recording paper are exposed through the mask original formed on the 6 sides of the heat sensitive recording paper. The image is recorded. In this way, the light-sensitive and pressure-sensitive recording paper 21 through which the cyan, magenta, and yellow coloring base materials are passed is first provided with a first filter portion 12a that transmits only light with a wavelength of 350 nm, corresponding to the spectral peak sensitivity of 350 nm for cyan; Illumination 9A through the red (R) mask original plate
As a result, the cyan microcapsules of the photosensitive and pressure sensitive recording paper 21 are photocured. Next, the print head 1 etc. are returned to their original positions, and the thermal recording paper 6 released by the operation of the solenoids 31, 32, 33 is fed in a fixed amount by a signal sent from the driver circuit 41 to the motor b, and the photo interrupter 51 is used to feed the thermal recording paper 6 to the print head. After setting the initial position of 1, the thermal recording paper 6 is fixed again using the fixing member, and this time it is set to green (G).
) The print head 1 is moved in the sub-scanning direction to print, and a mask original corresponding to the green (G) image data is created and exposed. At this time, the filter 12 has a magenta spectral peak sensitivity of 385n.
The light beam from the light source 11 is set in a second filter part 12b that transmits only light with a wavelength of 385 nm corresponding to the wavelength 385 nm, and the light beam of the light source 11 is exposed to light by passing through the second filter part 12b and the green (G) mask original plate. The magenta microcapsules on the pressure-sensitive recording paper 21 are selectively photocured in accordance with the image data. In this way, after exposing the green (G) image data onto the photosensitive and pressure sensitive recording paper 21, the print head 1 takes in the blue (B) image data from the data input section 7 and prints the blue (B) image data. Exposure is performed while forming a mask original plate, and at this time the filter has a yellow spectral peak sensitivity of 47
A second third filter portion 12G that transmits only light with a wavelength of 475 nm corresponding to 5 nm is disposed below the light source 11,
The yellow microcapsules of the photosensitive and pressure sensitive recording paper 21 are selectively photocured through the blue (B) mask original plate. In this way, the photosensitive and pressure sensitive recording paper 21 is colored red (R).
, green (G).

When exposed to light using the three mask original plates of blue (B), the light-sensitive pressure-sensitive recording paper 21 is transferred to the pressure fixing roller 23 and the opposing roller 2.
4, and is pressure-fixed. This pressure fixing breaks the uncured microcapsules and mixes with the color developer to produce each color, reproducing a color original. Thus, according to the present invention, the creation of mask masters for each color of red, green, and blue, and the exposure of the photosensitive and pressure sensitive recording paper using the respective mask masters proceed simultaneously. Therefore, even in the case of color copying, the exposure time is shortened.

It should be noted that the present invention is not limited to the above-mentioned embodiments, and the shape and configuration of each part can be changed arbitrarily without departing from the spirit of the invention. For example, it may be used as a printer instead of a copying device.

[Effects of the Invention] As is clear from the detailed description above, according to the recording device of the present invention, line exposure is performed sequentially at the same time as a light-shielding image is formed on the light-transmitting film surface. There is no need to separate the creation time and the exposure time, which saves time. Furthermore, if line exposure is used instead of surface exposure, the light source can be placed close to the surface of the light-transmissive film, and the apparatus can be made more compact and a light source with a small amount of light can be used. Moreover, it has many advantages such as being inexpensive and easy to maintain.
