Title: Color recording device
Inventor: TANAKA NOBUYUKI
IPC: G03G15/01
Filed: 1989-12-28
Abstract: PURPOSE:To prevent color slurring caused by the inadequacy of destaticization of a recording paper by providing a vacuum suction means for vacuum-sucking the recording paper held on an endless belt and forming a recessed part on the endless belt. CONSTITUTION:The vacuum suction means 22e and 24 for vacuum-sucking a recording paper held on the endless belt 22c to the belt 22c are provided, and the belt 22c has the recessed part 22d where a clamping member is allowed to escape. Therefore, when the recording paper is conveyed by the clamping member between toner recording units, the recording paper is held on the endless belt 22c of an endless holding belt assembling body 22 and positively vacuum- sucked by the vacuum suction means 22e and 24. Even when the intermediate part of the recording paper is swollen by the shortage of destaticization, the swollen part is restored to an even state on the belt 22c. Since the clamping member is allowed to escape to the recessed part 22d of the belt 22c, the leading edge side of the recording paper is made even with respect to the belt 22c. Thus, the color slurring caused by the lack of destaticization of recording paper is eliminated.

Title: Three-dimensional image display device
Inventor: HASEGAWA NOBORU
IPC: G03C9/00
Filed: 1993-12-06
Abstract: PURPOSE:To provide a three-dimensional image display device for which an integral plate two-dimensionally arranged with optical elements is utilized and with which three-dimensional images are observable in a wide visual field range by forming the proximate scattered light from a virtual object to be displayed. CONSTITUTION:The observation images of the virtual object displayed from the individual lens positions constituting the integral plate 4 are calculated and the two-dimensional images arranged with these images on one screen are displayed in an image display plate. The parallel ray fluxes past this plate are converted to the proximate scattered ray groups formed by sampling the scattered spherical waves from the virtual object at the lens pitch of the integral plate 4 when the parallel ray fluxes described above are projected onto the integral plate 4. An observer feels as if these ray groups are the scattered light from the virtual object when the observer observes the ray groups and, therefore, the observer is able to recognize the ray groups as the three- dimensional images. Since these ray groups propagate in the space in the adjacent state without overlapping on each other and, therefore, the normal three- dimensional images are observed in a wide visual field range.
