PURPOSE:To obtain an erect real image by a simple constitution, by combining a multilens array sheet and a multiprism array sheet so that they are in phase with each other. CONSTITUTION:This element is constituted by combining a multilens which has been formed in one body by a plastic member, etc., and a multiprism array sheet which has been formed in one body by a plastic member, etc., so that they are in phase with each other. The theory of this invention is explained as below. When an in-mirror prism lens assembly body consisting of an image formation lens 2 and a prism 3 is provided on the front of the original surface, a pattern P0 on the original surface becomes a real image P1 which is errect in the Y direction and is inverted in the X direction. When the assembly body consisting of plural image formation lenses 2 and prisms 3 in the Y direction by utilizing this theory, a real image of composite pattern can be obtained. |
