DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lenticular lens sheet for printing a predetermined image thereon by a thermal transfer recording device or the like to provide a stereoscopic image, and a plurality of the lens sheets for accommodating the lens sheet. The present invention relates to a cartridge for an image printing lenticular lens sheet to be loaded into a cartridge, and to provide a specific configuration capable of easily preventing erroneous conveyance of the lens sheet.

[0002]

2. Description of the Related Art Conventionally, in an image forming apparatus using silver halide photography, there has been known a method of forming a plurality of images in parallel with a lens pitch of a lenticular lens sheet to provide a series of three-dimensional images. However, in the case of the method using silver halide photography, the image on the negative film is moved in parallel with the lens pitch of the lenticular lens sheet at regular intervals, and exposure is performed, followed by development processing to complete a stereoscopic image. . In this method, the connection between images becomes unclear due to the accuracy at the time of exposure, and much time is required because processing such as exposure and development is required.

[0003]

SUMMARY OF THE INVENTION A basic object of the present invention is to provide a three-dimensional image having immediacy and high accuracy. By improving the lenticular lens sheet used in the thermal transfer recording apparatus, it is possible to obtain a good image with improved image joining accuracy, and to improve the ease of use during printing. It is better.

[0004]

In order to improve the joining accuracy of the images of the present invention, one side of the lenticular lens sheet in the longitudinal direction is configured to be parallel to the lens pitch, and one side is set as a printing reference side. By performing printing, the connection between images is clarified. Also, in order to prevent erroneous transport of the printing reference surface and the printing surface of the lenticular lens at the time of printing, a recess is provided on the lenticular lens so that the printing reference side can be distinguished. A window is provided to determine whether or not is stored in a normal orientation.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of a lenticular lens sheet and a cartridge thereof according to the present invention will be described below together with an embodiment of a thermal transfer recording apparatus.

In FIG. 1, reference numeral 2 denotes Y as shown in FIG.
(Yellow) 3, M (magenta) 4, and C (cyan) 5, an ink sheet in which three sublimable inks are sequentially arranged. The ink sheet is wound between the supply reel 1a and the take-up reel 1b, and the heating elements are lined. The stage 14 is disposed between the thermal head 6 and the stage 14. Here, a platen 7 having an elastic body is stuck on the upper surface of the stage 14, and a rack 1 for stage transfer is mounted on the lower surface of the stage 14.
The stage 14 is engaged with the drive screw 18 so that the stage 14 can be reversibly conveyed in the direction of the arrow 26. Next, the actual operation will be described.

First, as shown in FIG. 4, a quadrilateral lenticular lens sheet (hereinafter referred to as a lens seed) 1
One surface has a smooth printing surface, and the other surface has a lenticular lens surface on which a number of convex ridges having a cross section parallel to each other are formed.
It is mounted on the thermal transfer recording apparatus in a state where it is stacked and stored in a predetermined direction inside. Next, in response to a print command, the lens sheet 11 is taken out from a carry-out port provided near the bottom surface of the cartridge 19 by a pickup means (not shown), moved to a position between the conveying rollers 8 and 9, and thereafter shown in FIG. As described above, the sheet is conveyed onto the stage 14 until the conveying force of the conveying rollers 8 and 9 disappears. Here, a lens sheet rear holding member 15 that can be opened and closed in synchronization with the movement position of the stage 14 is installed behind the stage 14, and the stage 14 moves in the direction of the arrow 26. With this movement, the lens sheet rear holding member 15 is moved by the arrow 27.
In the center of the rear edge of the lens sheet 11, and as a result, a recess B formed at the center of the front edge of the lens sheet 11 and longer than the recess A.
When the stage 14 moves in the direction of the arrow 26, the leading end of the lens sheet 11 is moved to the lower end of the lens sheet top holding member 16.
Contact 0.

Next, on the right end of the stage 14, a lens right end holding member 2 suspended by two coil springs 23 and 24 is provided.
The lens right end holding member 20 is also configured to be reversibly movable in the direction of the arrow 32 in FIG.

When the stage 14 is further moved in the direction 26, the lens right end holding member 20 is moved in the direction of the arrow 32 to press the printing reference side of the lens sheet 11 against the lens left end holding member 25. Through the above steps,
The lens sheet 11 is conveyed onto the stage 14, and the holding operation is completed.

In this state, the stage 14 is further moved by the arrow 2
Y (yellow) of the color material layer 3 selectively formed on the ink sheet 2 according to an image signal to be recorded by the thermal head 6 on the lens sheet 11 by moving in the six directions.
Record. When this recording operation is completed, M (magenta) of the color material layer 4 and C (cyan) of the color material layer 5 are sequentially recorded.

In this embodiment, concave portions A and B having different lengths are formed on both sides of the printing reference side on the recording surface side of the quadrilateral lens sheet 11, and the printing reference side is determined based on the concave portions A and B. Can be performed, but the shape is not limited as long as it can be easily determined. Cartridge 1
9, a through hole C is formed in the rear side surface so that when the lens sheet 11 is stored in a predetermined normal direction, the end of the concave portion A is exposed as shown in FIG. If the direction of the lens sheet 11 or the lamination direction is different, it can be easily determined.

[0012]

By configuring the lenticular lens sheet and the cartridge as described above, erroneous conveyance of the lenticular lens sheet can be easily and inexpensively prevented, so that the reliable and continuous operation is clear. It is possible to provide simple stereoscopic images.
