Abstract: A photographic camera system includes a photographic camera that can successively expose a photographic film in different frame sizes and an automatic printer for automatically printing the processed photographic film exposed with those different frame sizes. The camera varies the width of an exposure opening in the camera body in the film-feed direction and the film is fed a length corresponding to the width of the exposure opening. The photographic camera records an exposure opening position signal indicative of the size of the exposure opening on the photographic film, and the automatic printer automatically prints the photographic film using the exposure opening position signal detected from the photographic film.

Abstract: A multiple access transmitting method in communication resources using a multicarrier signal in which subcarriers of a predetermined number are allocated with a predetermined frequency separation, includes a coding processing step of processing a plurality of individual signals generated from a plurality of signal sources, respectively, a multiplexing step of multiplexing output signals obtained in the coding processing step, and a converting step of converting an output signal obtained in the multiplexing step into a multicarrier signal.

Abstract: In a filter device a reference clock generator produces a reference clock signal having the stated frequency; a data signal generator generates a data signal which is asynchronous with the reference clock signal; trigger signal generator produces a trigger signal when a discrepancy which exceeds the interval of one clock of the reference signal occurs between the reference clock signal and the data signal; and a digital circuit re-samples the data signal in accordance with the reference clock signal and changes the magnification ratio of the re-sampling by increasing or reducing the sampling period of re-sampling by one clock interval of the reference signal.

Abstract: An optical disc player having a disc tray on which an optical disc is loaded and which is supported by a first chassis so that it can be freely moved between a disc loading position and a disc reproducting position, a second chassis to which a disc rotating device is supported and which is provided to move in a vertical direction relative to the first chassis, an elevating mechanism for moving the second chassis in the vertial direction, an optical pickup supporting arm supported to the second chassis adapted to skew relative to a disc surface and on which an optical pickup is provided, a transmission mechanism for transmitting a rotation force of a motor, a rotation operation member rotated by the transmission mechanism and which has a gear portion to be meshed with the disc tray to move the same and a cam groove engaged with the elevating mechanism to move the second chassis in the up and down direction, and a cam member rotated by the rotation operation member and which has a cam groove engaged with the op
