Abstract

A booklet includes a sheet-like first substrate, and a sheet-like second substrate that is attached to the first substrate. The first substrate includes a light-transmitting region, and an optical functional unit is provided to the light-transmitting region. A latent image is provided to a surface of the second substrate that is opposite to the first substrate at a position corresponding to the optical functional unit. The latent image manifests when the optical functional unit operates by overlapping the first substrate with the second substrate.

First claim

What is claimed is:

1. A booklet comprising:
a first sheet substrate comprising a light-transmitting film having a light transmittance of 90% or more at a wavelength band of visible light, the first sheet substrate folded in half along a folding line defining two portions that are adhered to each other;
an optical functional unit provided to the light-transmitting film and having a polarization function;
a second sheet substrate saddle-stitched under the first sheet substrate;
a binding member stitched into the first sheet substrate at the folding line, comprising an anti-counterfeiting member, and saddle-stitching together the first sheet substrate and the second sheet substrate;
a latent image provided to a surface of the second sheet substrate that is opposite to the first sheet substrate at a position corresponding to the optical functional unit, provided at a central portion of the second sheet substrate, and formed in the second sheet substrate in a continuous manner across the folding line where the second sheet substrate is attached to the first sheet substrate, the latent image manifesting when the optical functional unit operates by overlapping the first sheet substrate with the second sheet substrate;
an inlet comprising at least an IC chip and an antenna interposed between the two portions of the first sheet substrate adhered to each other; and
a shielding layer covering at least a part of the inlet and provided so as not to expose the IC chip,
the inlet and the shielding layer spaced from the binding member by a distance of at least 0.5 mm or more from the folding line.

2. The booklet according to claim 1 , wherein the first sheet substrate and a substrate of the inlet each comprise thermoplastics.

3. The booklet according to claim 1 , wherein the optical functional unit comprises a polarization film that is interposed between the two portions of the first sheet substrate adhered to each other.

4. The booklet according to claim 1 , wherein at least a part of the first sheet substrate is configured as a polarization film.

5. A method of manufacturing a booklet, the booklet including a first sheet substrate comprising a light-transmitting film having a light transmittance of 90% or more at a wavelength band of visible light, an optical functional unit provided to the light-transmitting film, a second sheet substrate saddle-stitched under the first sheet substrate, a binding member comprising an anti-counterfeiting member and stitching the first sheet substrate and the second sheet substrate, and a latent image provided to a surface of the second sheet substrate that is opposite to the first sheet substrate at a position corresponding to the optical functional unit, provided at a central portion of the second sheet substrate, and formed in the second sheet substrate in a continuous manner across a folding line where the second sheet substrate is attached to the first sheet substrate, the latent image manifesting when the optical functional unit operates by overlapping the first sheet substrate with the second sheet substrate, the method comprising:
saddle-stitching a first sheet substrate, which comprises a light-transmitting film and is provided with an optical functional unit, having a polarization function, at the light-transmitting film, onto a second sheet substrate using a binding member, the binding member stitched into the first sheet substrate at the folding line of the first sheet substrate defining two portions of the first sheet substrate, and the second sheet substrate provided with a latent image, which is manifested by allowing the optical functional unit to operate, on a surface of the second sheet substrate that is opposite to the first sheet substrate at a position corresponding to the optical functional unit;
folding the first sheet substrate in half along the folding line defining the two portions, and adhering the two portions to each other;
interposing the optical functional unit or an inlet comprising at least an IC chip and an antenna between the two portions of the first sheet substrate;
forming a shielding layer that covers at least a part of the inlet so as not to expose the IC chip; and
disposing the inlet and the shielding layer so as to be spaced from the binding member by a distance of at least 0.5 mm or more from the folding line.

6. A method of manufacturing a booklet, the method comprising:
saddle-stitching a first sheet substrate, which comprises a light-transmitting film having a light transmittance of 90% or more at a wavelength band of visible light and is provided with an optical functional unit, having a polarization function, at the light-transmitting film, on to a second sheet substrate using a binding member, the binding member stitched into the first sheet substrate at a folding line of the first sheet substrate defining two portions of the first sheet substrate, the second sheet substrate provided with a latent image, which is provided at a central portion of the second sheet substrate, is formed in the second sheet substrate in a continuous manner across the folding line where the second sheet substrate is attached to the first sheet substrate, and is manifested by allowing the optical functional unit to operate, the latent image being on a surface of the second sheet substrate that is opposite to the first sheet substrate at a position corresponding to the optical functional unit;
folding the first sheet substrate in half along the folding line defining the two portions, and adhering the two portions to each other;
interposing the optical functional unit or an inlet comprising at least an IC chip and an antenna between the two portions of the first sheet substrate;
forming a shielding layer that covers at least a part of the inlet so as not to expose the IC chip; and
disposing the inlet and the shielding layer so as to be spaced from a binding member comprising an anti-counterfeiting member by a distance of at least 0.5 mm or more from the folding line.
