One of the first and second mechanisms is a focus adjusting mechanism, and the other is an aperture adjusting mechanism.

Abstract: An image recording apparatus records an image on an elongated continuous form photosensitive recording medium capable of receiving a latent image of an output image to be formed, and a cut sheet type of a developer recording medium provides an output image upon reaction with the latent image on the photosensitive recording medium. The recording apparatus includes an exposure portion for exposing the elongated continuous form photosensitive recording medium fed along the recording medium feeding path to a light image to form the latent image thereon. The exposure portion includes an exposure position whereat a leading edge of an unexposed portion of the photosensitive recording medium is located prior to imaging. A developing portion is disposed downstream of the exposing portion with respect to the recording medium feeding path and develops the exposed photosensitive recording medium superposed with the developer recording medium.

The coating device may apply to the medium at least one of the photosensitive microcapsules and developer material which serve as the at least one kind of toner, according to the source image information, and the exposing device may expose to the radiation the medium having the microcapsules serving as the photosensitive toner so as to form microcapsule-based latent images.

Abstract: An acoustical partition for use in home, office and industrial environments includes a generally rectangular, rigid, hollow frame whose interior opening is filled with an acoustical core wherein the outer planar surfaces of the frame and core are covered with further insulation material and a fabric outer layer. The interior acoustical core is configured with an alternating sequence of insulation material strips wherein the alternating strips of insulation material may either be different materials of the same density, the same material with different densities, different materials and different densities and with all of the foregoing may be either the same or different thicknesses.

Abstract: A lens-fitted photographic film package for steroscopic photography, wherein a plurality of images of the same subject are taken simultaneously through a corresponding number of taking lenses disposed horizontally side by side at a given distance from each other. Behind the respective taking lenses, exposure chambers and exposure frames for defining the respective exposure areas on the film surface are formed. The exposure frames are each gently curved, and a guide surface for supporting the rear surface of the film is curved complementarily to the exposure frames. Pressing members formed in the guide surface press the film against the end surfaces of walls separating the exposure frames, so as to curve the film along the exposure frames. The film is thus wavy, with forwardly concave film portions in the exposure frames alternating with rearwardly concave film portions between the exposure frames.
