Abstract: With the splicing get started, braking becomes strong and the old core decelerates, when the capstan roll comes to be free run. The speed reference to the second motor is a summed-up speed of "line speed minus capstan speed" and compensated portion of the tension. At once when the old core starts deceleration, the accumulation roll unit starts moving. The capstan roll is accelerated at a certain rate, when the new core is drawn out, up until the speed reaches "line speed plus overrun speed". When the accumulation roll unit reaches the synchronous position, the overrun becomes "0" and the capstan roll synchronizes with the line speed.

Abstract: The invention relates to a monochromator which disperses the light containing many wavelengths emitted from a source of light, and which takes out a given wavelength component only. The invention realizes a monochromator which can take out the light of a single wavelength maintaining a very high wavelength purity by using a plane grating C which can be easily manufactured maintaining a high precision and by employing a very simply constructed wavelength sweeping mechanism in which the distance between the incident slit A and the diffraction grating C as well as the distance between the exit slit B and the diffraction grating C are maintained constant, instead of using a concave grating that had been indispensable in the conventional monochromator adapted to the wavelength regions of from soft X-rays to vacuum ultraviolet rays.

Abstract: This invention concerns an image processing system which is constructed by combining a plurality of image readers each adapted to read an image electrically and produce image data as output and a printing means for producing the image on a recording medium based on the introduced image data. During the course of transfer of an image signal from the image readers to the printing means, the image processing system automatically delays the actuation of the image readers when the mode of prohibiting the transfer of image signal exists, whereas the image processing system automatically actuates the image readers immediately after the mode of prohibiting the transfer of image signal changes to the mode of permitting the transfer.

Abstract: A film image projecting apparatus such as a microfilm reader and a microfilm printer adapted to automatically retrieve desired information by searching blip marks provided laterally of frames in a roll film. Conventionally, a roll film containing a plurality of rows of frames has been retrieved in most cases by manually placing a target frame in an exposure section. The known apparatus also has the disadvantage of blip marks becoming displaced from an illuminated area when an image is projected in magnification onto a screen, thereby impairing the retrieval operation. The present invention provides a film image projecting apparatus having means for eliminating this disadvantage. More particularly, the disclosed apparatus comprises a film transport mechanism, a cross slide mechanism, a projecting optical system, and a control device for suitably controlling these elements to enable desired information retrieval.
