Title: Recording sheet
Inventor: SATO HIDEKI
IPC: B41M5/50
Filed: 1995-11-27
Abstract: PROBLEM TO BE SOLVED: To obtain excellent slip properties without damaging printing quality by providing a porous ink receiving layer on one surface of a base material sheet and forming unevenness on the other surface thereof by a laser marker. SOLUTION: Unevenness is formed on the rear surface of a base material sheet by a laser marker. It is pref. to form regular patterns because slip properties between recording sheets become uniform but irregular patterns may be formed. As the regular patterns, geometric patterns such as checkered patterns, polka-dot patterns or checked patterns or patterns wherein company names or commodity names or logomarks of them are regularly arranged are designated. Since unevenness is formed on the rear surface of the base material sheet by the laser marker, blocking between recording sheets is suppressed and, as a result, slip properties between sheets are enhanced.

IPC: G03H1/04
Filed: 1989-11-28
Abstract: PURPOSE:To reduce factors deteriorating characteristics by adhering optical members each having a refractive index close to that of a photographic plate for a hologram to both sides of the dry plate and irradiating the dry plate with object light and reference light through the separate optical members. CONSTITUTION:Optical members 2, 3 adhered to both sides of a dry plate 1 for a hologram are square pillar-shaped optical glass members having slanting faces 21, 31 adhered to the photographic plate 1, respectively. Object light L1 incident on a side face 22 passes through the member 2, further passes through the photographic plate 1 and enters the member 3 at an emergent angle theta'1. Since the central axis of the member 3 coincides with the emergent direction of the light L1, the light L1 perpendicularly enters the bottom 33 of the member 3 and passes through the member 3 without reflection. Reference light L2 incident on a side face 32 passes through the member 3, further passes through the photographic plate 1 and enters the member 2 at an emergent angle theta'2. Since the central axis of the member 2 coincides with the emergent direction of the light L2, the light L2 passes through the member 2 without reflection. Harmful interference fringes are not formed on the photographic plate 1 at the time of forming a hologram and factors deteriorating characteristics are reduced.
