In the display mode in the print mode, a color image is separated into each of the three primary colors, and first, for example, an image separated into red is displayed on the liquid crystal panel 32, and at the same time, the red LED 35 emits light. The red light reflected by the liquid crystal panel 32 becomes a light amount corresponding to the reflectance of each liquid crystal segment, and gives a red exposure to the photosensitive surface 25a.

After the red exposure is completed, the image separated into green is displayed on the liquid crystal panel 32 in the same manner.
At the same time, the green LED 36 is caused to emit light. Then, a green exposure is given to the photosensitive surface 25a, and after this, the image decomposed into blue is displayed on the liquid crystal panel 32, and at the same time, the blue LED 37 is made to emit light. In this way, red,
Exposure is performed in green and blue colors.

In the display mode of the observation mode, an image obtained by separating a color image into each of the three primary colors is sequentially displayed on the liquid crystal panel 32 at fixed time intervals, and in synchronism therewith, the three primary colors of the LED unit 33 are provided.

An image may be displayed by causing the unit to emit light.

Alternatively, the liquid crystal display unit 31
Instead of a liquid crystal panel, a well-known DLP
A (digital micromirror device) type electronic display unit may be used. The DLP-type electronic display unit forms an image by displaying light and shade in a time-division manner by changing the reflection angle of a micromirror arranged for each pixel at a very high speed.

Has become.

The magnifying lens 41 is arranged between the movable mirror 39 and the fixed mirror 44, and the magnifying lenses 42 and 43 are arranged between the fixed mirror 44 and the observation eyepiece window 5. The magnifying lenses 41, 42, and 43 magnify the image formed on the liquid crystal display unit 31 and emit the magnified image from the observation eyepiece window 5. The observation eyepiece window 5 has a magnifying lens 41,
Since the image is enlarged by 42 and 43 and the formed image is emitted, an image displayed on the liquid crystal display unit 31 is projected upside down. However, in the observation mode, the liquid crystal display unit 31 displays an image that is inverted from the normal image in the vertical direction, so that an image in the correct direction can be observed from the observation eyepiece window 5.

When the mode is switched to the print mode, the movable mirror 39 rotates the hinge 45 in the counterclockwise direction in FIG.
Rotate to the retreat position indicated by the two-dot chain line in the figure. Thus, in the print mode, the movable mirror 39 does not obstruct an exposure optical path described later.

The position of the movable mirror 39 reflects the retracted position and the image on the liquid crystal display unit 31 in accordance with the positions of the indicators 17b and 17c indicating the print mode and the observation mode selected by the mode changeover switch 17. The switching mechanism can be switched between the observation positions to be switched on and off.
The rotation is mechanically transmitted by connecting the rotation shaft 7 and the hinge 45 of the movable mirror 39 directly or indirectly through a gear or the like.

The exposure optical system 47 includes a magnifying lens 48, a fixed mirror 49, and a movable mirror 50, as shown in FIGS. When the mode is switched to the print mode, as described above, the movable mirror 39 rotates to the retracted position and the movable panel 12 rotates to the open position, so that the movable mirror 50 held on the back surface of the movable panel 12 is also integrated. And rotate to the position shown by the two-dot chain line in the figure.

In the middle of the exposure optical path from the liquid crystal display unit 31 to the photosensitive surface 25a, a fixed mirror 4 is provided.
9 and a movable mirror 50 are arranged, and the observation optical path is reflected at two places and bent at a right angle. The magnifying lens 48 magnifies the image formed on the liquid crystal display unit 31 and gives exposure to the photosensitive surface 25a.

On the photosensitive surface 25a, the image displayed on the liquid crystal display unit 31 is formed as an image whose right and left are inverted.
Since the liquid crystal display unit 31 displays an image obtained by inverting the normal image in the left-right direction, an image can be formed in the correct direction on the photosensitive surface 25a.

As described above, the printer 2 can be driven by a built-in battery in order to make it portable and convenient. As shown in FIG. It is stored below the optical system 38.
