An optical display apparatus is provided that can utilize a low intensity point light source and that requires a small physical profile. The optical display apparatus comprises an image display apparatus including at least one point light source to form an image to be displayed for viewing, a hologram screen that defracts and reflects light from the point light source, and an imaging optical system arranged to adjust a focus in one direction of the image so that the point light source of the optical display apparatus is focused to a line on the hologram screen. The optical display apparatus reconstructs and images the image displayed on the image display apparatus on a virtual display plane.

An IC package transfer mechanism for transferring molded IC packages to and from a flat tray with a large number of IC holder nests in an array and an IC magazine adapted to accommodate a large number of IC packages in a row within a tubular housing to be turned into a tilted position in loading and unloading operations to let IC packages slide into or out of the cylindrical housing automatically by gravity. The IC package transfer mechanism comprises: an IC transfer block movably supported for displacement between a horizontal position and a tilted position, and internally provided with a slide channel with stopper devices for holding a plural number of IC packages in predetermined IC stop positions, the slide channel having an open entrance at an end to be turned into the tilted position and connected to an outlet end of a tubular IC magazine set in a similarly tilted position for transferring IC packages to the slide channel automatically by gravitational sliding movements of individual IC packages, along with top openings bored over in a top wall over the IC stop positions to permit access to IC packages in the slide channel by a handling device.

A transfer mechanism for transferring molded IC device packages or the like between different types of trays which have IC package holder nests in differently spaced arrays. The transfer mechanism includes a suction gripper assembly supported on a horizontally and vertically movable robot arm, and having four suction heads mounted separately on four support blocks on a mounting plate. The four support blocks consist of a first support block fixed in a predetermined reference position on the mounting plate, second and third support blocks movably supported on the mounting plate for movements toward and away from the first support block in perpendicularly intersecting directions, and a fourth support block movably supported on the mounting plate for movements toward and away from the first support block in a diagonal direction following movement of at least one of the second and third support blocks.

A holographic multiplexer and holographic demultiplexer, which has a diffraction grating formed of a hologram with an interference pattern produced by interference of two wave fronts, of which at least one wave front is of an aspherical wave and the other is of, for example, a spherical wave, and its manufacturing method are disclosed. The aspherical wave is used for correction of aberration and provided by obtaining the phase function .phi..sub.G of the aspherical wave using a computer generated hologram and through an optical method or an electron-beam direct drawing method. The hologram serving as the diffraction grating for the holographic multiplexer/demultiplexer is produced by a two-beam interference method of an electron-beam direct drawing method. As the result, a holographic multiplexer/demultiplexer having a high degree of multiplexing, which is compact in size, and exhibiting low loss of light can be provided.
