Abstract: A projecting device is provided which consists of an enlarged head at one end of a flashlight, the enlarged head having a transverse slot therein. A lens is positioned at a front end of the enlarged head, while a light bulb is positioned at a back end of the enlarged head. A slide is insertable into the transverse slot in the enlarged head, so that an illuminated image from the slide may be projected onto a viewing surface.

Abstract: It is an object of the invention to provide a video projector which can be driven by a battery and can be reduced in both size and weight. A packing case for a video projector is composed of a cabinet, which is divided into two upper and lower parts, and a cover disposed behind the cabinet. The cover is disposed removably with respect to the cabinet. By opening the cover situated behind the projector light source, a lamp forming the projector light source can be replaced easily. Also, the cover includes on the back surface thereof a battery mounting portion for mounting a battery used to drive the projector, so that the battery can be mounted to the outer back surface of the cover.

Abstract: A logo projector is provided which consists of a flashlight that can be held in a hand of a person using said logo projector. A bezel is affixed to the flashlight so that when the flashlight is turned on a beam of light will pass through the bezel. An elongated opaque tube is affixed at a first end to the bezel. A focusing lens is affixed to a second end of the elongated opaque tube. A transparent member having an opaque logo on the center of the back surface thereof is also provided. The transparent member is affixed to the first end of the elongated opaque tube adjacent the bezel so that when the flashlight is turned on the beam of light passing through will cause an image of a silhouette of the opaque logo from the transparent member to be projected onto a distant surface.

Abstract: A portable projector which can be used at a location where no commercial ac power source is available and can be carried readily, has a battery section for supplying power therefrom, an illuminating section including a lamp for receiving power from the battery section and emitting light therefrom, a picture image holding section for forming a picture image thereon and for being irradiated by light emitted from the irradiating section to pass the light in accordance with the picture image formed thereon, and a lens section for enlarging a picture image of light passing through the picture image holding section. The battery section, illuminating section, picture image holding section and lens section can be removably coupled on a common optical axis to each other.

Abstract: A film projector toy is described, including a projector casing and a film cassette received by the casing. The film cassette includes a plurality of films movable one relative to another. Indicia representing different portions of a complete, predetermined picture image are illustrated on each film and the films are superimposed in the cassette. The indicia are then projected, for example, on a wall, so as to form the complete picture image. At least one film is then moved relative to the other films so that the indicia are moved, thereby creating a moving picture image.

Abstract: A miniature movie projector for viewing a continuous loop movie film in ambient light is disclosed. A hand operated spring mechanism moves the continuous loop movie film such that ambient light entering the projector enables the movie to be viewed. The projector is constructed such that it can be worn as a pendant.

Abstract: A hand-held transparency projector includes a housing having a recess formed in the housing for carrying a film cartridge, and a projection aperture in one end of the housing through which the images on the film in the cartridge may be projected. The housing carries a film-driving mechanism for advancing the film within the cartridge past the projection aperture when the cartridge is carried within the recess of the projector. The film-driving mechanism includes a claw mounted for slidable forward and return movements within the housing, the claw engaging perforations in the film at the end of the forward movement and advancing the film during the return movement in discrete steps of one frame.

Abstract: A portable microform reader is provided with a microform carrier and a projection system for projecting an enlarged real image of the information carried on a portion of the microform onto a viewing screen. A binocular magnifying system is arranged for viewing the screen and for further enlarging the image thereon to produce a virtual image of acceptable reading size. The projection system comprises a source of illumination, a condenser lens, and a projection lens for projecting an image of the information carried on the microform onto the screen. The magnifying system may consist of appropriate binocular lenses where such lenses, in combination with prismatic converging means, produce the desired magnification. Beam splitting means may alternately be provided to eliminate the need for prismatic converging means, and a mirror arrangement may be provided to "fold" the projected beams for further limiting the size of the reader.

Abstract: A hand-held projector for projecting from a transparency on a film strip and image onto any desired surface. The film strip with a series of transparencies is guided in a casing which has a front peripheral wall portion carrying an objective behind which is situated a light source with the film being guided between the light source and objective. A manually operable member is accessible for feeding the film strip frame by frame along the guide in the casing so that successive transparencies will be projected. Batteries from which energy is derived for the light source are situated in the casing on opposite sides of the light source so that a balanced compact arrangement is achieved.
