PROJECTION OPTICAL SYSTEM, PROJECTION-TYPE IMAGE DISPLAY DEVICE, AND IMAGING DEVICE
20200278600 · 2020-09-03 · ·

A projection optical system has first and second optical systems disposed in order from a demagnification side toward a magnification side. An intermediate image is formed between demagnification-side and magnification-side imaging surfaces. The second optical system is an optical element having first transmission, reflecting, and second transmission surfaces in order from the demagnification toward the magnification sides. The first transmission and reflecting surfaces are located at one side with respect to an optical axis. The second transmission surface is located at the other side with respect to the optical axis. The reflecting surface has a concavely curved surface shape. The second transmission surface has a convexly curved surface shape protruding toward the magnification side. The optical element has a first member and a second member different in refractive index from the first member. A bonding surface between the first member and the second member has a curved surface shape.

A projector assembly is configured to continue reeling film when there is a break in the film. The projector assembly has an upper projector joined to a top snorkel with a top mirror. A top lens box mirror is attached to the top snorkel proximate a bottom lens box mirror. A bottom lens to a second projector is aligned with the bottom lens box mirror. A locking assembly has a rising door with a pressure release arranged proximate to a slide plate joined to a slide arm. A motor and a release lever are joined to the slide arm. Film is rounded through the locking assembly such that when the film tears the locking assembly continues to route film through the projector to enable the projector assembly to continue reeling the film.
