[0011]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A recording medium storage device 200 according to the present invention will be described with reference to FIG. FIG. 3 is a schematic center sectional view of the recording medium storage device 200. In the recording medium storage device, the instant film 1 described above is used.
00 and the film cartridge 120 are used. Further, the recording medium storage device 200 includes three parts: an optical head section 210, a transport section 220, and a storage section 260.

The optical head unit 210 has three color L light sources.
An LED unit 211 in which EDs are arranged close to each other in the vertical direction, a toroid lens 213 having a plane and a cylindrical lens surface, a parabolic mirror 212 for reflecting a light beam 217 emitted from a light source in a fan shape into a parallel light flux, The parallel light flux passes through the toroid lens 213 again and is converged in a sharp line at the exposure point P on the photosensitive surface 102. It has a liquid crystal light shutter array 215 for selectively transmitting or blocking, and a mask member 216. The liquid crystal light shutter array 215 has a length of 162 μm and a length of 640 pixels × 640 pixels on the photosensitive surface 102 of the instant film 100.
A color latent image of a line can be formed. The method of forming a latent image will be described later.

The transport unit 220 includes the film cartridge 1
20 is provided adjacent to the storage section 260 in which the recording medium 20 is stored.
It is conveyed in the direction of arrow Z by 2a and 222b and discharged. While the instant film 100 is being conveyed, the photosensitive surface 102 is exposed at the exposure point P by the optical head unit 210 to form a latent image. The developer pack 101 described above is disposed at the leading end of the instant film 100 on the downstream side in the transport direction. The developer pack 102 is squeezed by the developing roller pairs 222a and 222b, and the self-developing solution is It is configured to gradually spread on the exposed surface 102 of the instant film 100 after exposure. Therefore, the development of the latent image of the instant film 100 discharged from the recording medium storage device 200 is completed after a predetermined time has elapsed, and a color image is developed.

Since the development starts when the self-developing solution reacts with the photosensitive surface 102, it is important to prevent the self-developing solution from contacting the unexposed photosensitive surface 102. Therefore, as will be described later, the conveying roller pair 221a and 221b are configured to have a small diameter at the central portion thereof, and
2, so that the developing solution does not react with the photosensitive surface.

A rotary encoder 250 is provided on the shaft of the transport roller 221a. The control circuit 600 uses an encoder pulse generated by the rotary encoder 250 to determine the exposure timing of the optical head 210. It is configured to be.
The storage section 260 is configured to store the film cartridge 120 held by the holder 261.

FIG. 4 shows an encoder pulse (a) generated by using the rotary encoder 250, data transfer timing (b), and L supplied to the LED unit 211.
FIG. 9 is a diagram illustrating an ED light emission pulse (c) and LCS pulses (d) to (f) supplied to the liquid crystal shutter array 215. The liquid crystal shutter array 215 has only one row of 640 liquid crystal shutter elements that can be independently opened and closed in the direction perpendicular to the transport direction of the instant film 100 (the direction of arrow Z in FIG. 3). Each shutter element is
It is composed of a so-called normally white type liquid crystal that transmits light when no voltage is applied (0 V) and blocks light when a predetermined voltage is applied.

Each LED of the LED unit 211 is RG
B emits light in a time-division manner and emits light, whereby RG
Each of the B linear light beams is supplied to the liquid crystal shutter array 215.
And forms an image at predetermined positions on the photosensitive surface 102 at predetermined pitch intervals. FIG.
As shown in (b), image data for driving each shutter element of the liquid crystal light shutter array 215 is transferred in advance corresponding to the immediately preceding encoder pulse. Then, in synchronization with the encoder pulse (a), an LED light emission pulse is generated as shown in FIG. 4 (c), and the LED unit is repeated at predetermined time intervals while repeating the order of R, G, B. Each LED 211 is caused to emit light. Since the rotary encoder is provided coaxially with the transport roller 211a, it is synchronized with the transport of the instant film 100. Therefore, the LED is synchronized with the encoder pulse.
By generating the light emission pulse and the LCS pulse, it is possible to prevent the image quality from deteriorating due to uneven transport.

The LCS pulse shown in FIG. 4D is a signal for closing all the liquid crystal light shutter arrays 215,
In this case, a predetermined voltage is applied during the entire period of the light emission to close all the shutter elements. In this case, black is developed on the photosensitive surface 102 of the instant film 100 after development. The LCS pulse in FIG. 4E is a signal that closes the liquid crystal light shutter array 215 by half, and each of the colors LE
A case is shown in which a predetermined voltage is applied during a half period of the light emission of D to close all the shutter elements. In this case, after development on the photosensitive surface 102 of the instant film 100,
Gray color develops. The LCS pulse shown in FIG. 4F is a signal that opens all the liquid crystal light shutter arrays 215,
A case is shown in which no voltage is applied and all shutter elements are opened during the entire period of light emission of D. In this case, white color develops on the photosensitive surface 102 of the instant film 100 after development. As described above, by controlling the application time of the voltage applied to the liquid crystal light shutter array 215, in this embodiment, it is possible to express 64 gradations for each color.

At the end of each color exposure, a pair of positive and negative pulses is applied to all the shutter elements of the liquid crystal light shutter array 215 so that the image history immediately before each shutter element is not affected. . Further, in order to prevent the deterioration of the liquid crystal, the polarity of the voltage applied to the liquid crystal light shutter array 215 is inverted each time. In addition,
It is assumed that even if the polarity of the voltage applied to the liquid crystal light shutter array 215 changes, the opening / closing operation of each shutter element does not change.

Shall have. Each of the R, G, and B lights emitted by the optical head unit 210 forms an image having a width W on the photosensitive surface 102 of the instant film 100 at a predetermined pitch interval, as shown in FIG. I do.

FIG. 5A shows the point in time when the exposure with the R light is started. FIG. 5B shows the point in time when the G light exposure is started. Note that, by turning on the R light for a predetermined time and moving the instant film 100, R light

(C) shows the point in time when the exposure of the B light is started.
Note that the exposure of the section in the G layer by the G light has been completed by turning on the G light for a predetermined time and moving the instant film 100.

FIG. 5D shows a point in time when the exposure of the R light is started again. Note that, by turning on the B light for a predetermined time and moving the instant film 100, exposure of the section in the B layer with the B light has been completed. Similarly,
