Abstract

A slit head 76A is provided prior to intermittent feed rollers 73A and 73B. The slit head 76A is made of a rigid body such as magnetic iron and is used as a contact member. The slit head 76A is provided with a slit 78 on the side of a reference light L4 in the vicinity of an exposure position P1. The reference light L4 is transmitted through the slit 78 of the slit head 76A. In addition to magnetic iron, stainless steel and the like are used for the contact member 76A. On the side of an object light L3 at the exposure position P1, there is provided a presser plate member 76B for pressing the holographic recording medium 10 against the slit head 76A. The presser plate member 76B is also provided with a slit 82 and is arranged corresponding to an incident position of the object light L3. A magnetic member is used for the presser plate member 76B.

Description

technical field [0001] The invention relates to an image-recording device for creating a recorded holographic stereogram so that a photographed image or a computer-generated image can be viewed three-dimensionally. Background technique [0002] To create a holographic stereogram, for example, an object is photographed from different viewing points to produce many images that are identical to the original image. These images are sequentially recorded on a single holographic recording medium in the form of stripe or dot elemental holograms. [0003] For example, Figure 1 shows a holographic stereogram with disparity information only in the lateral direction. The subject 90 is cross-photographed from different viewpoints, resulting in a plurality of primary images 91a to 91e. The image recording device sequentially records these primary images on the holographic recording medium 92 in the form of a stripe-element hologram. [0004] Image information is obtained by photograph...
