Abstract: The invention provides an apparatus for sorting various kinds of coins into various categories of coins. To this end, the invention includes a semicircular member having a plane surface and an arc surface. The semicircular member is capable of rotating between a first position wherein the plane surface is disposed substantially in the plane defined by a guiding edge and the arc surface is disposed within a guide rail and a second position wherein the plane surface is disposed normal to the guiding edge and the arc surface faces towards the upstream of the coin feeding direction. The semicircular member rotates from the first position to the second position when a first group coin is fed to collide with the semicircular member so as to diverge the coin away from the guiding edge so that the circumferential end of the coin closest to the guiding edge is disposed on a sort-out opening. The semicircular member returns to the first position when the coin passes the semicircular member.

Abstract: A coin feeding apparatus for a coin handling machine of the rotatable disk kind includes a guide extending along the coin flow path in the vicinity of an opening of a guide ring. The guide is swingable between a first position where its face is smoothly aligned with the inner circumference of the guide ring and a second position where the face is not smoothly aligned. The guide means, when disposed in its second position, acts to prevent the jamming of coins when the coins are driven in a reverse direction back through the opening onto the rotatable disk.

Abstract: A reader printer for copying image information from a microfilm having a multiplicity of image frames recorded therein, frame marks for retrieval affixed thereon opposite the image frames, and batch marks for retrieval affixed thereon opposite the leading image frames of batches of image frames. When one of the batches of image frames is designated, the information contained in all the image frames in the batch is recorded sequentially from the last through the first of the image frames. The positioning of each of the image frames included within the designated batch at a prescribed location of the projected light path is accomplished by detecting the frame marks with a sensor, memorizing the positional relationship of the frame marks prior to the operation of print copying, and selectively imparting a motion to the microfilm based on the memorized data of position. The sensor is disposed at a position deflecting from the projected light path.

Abstract: A kit for the administration of a radiopharmaceutical liquid composition has been developed, which includes a radiation-shielding injector accompanied with a syringe-type vial having a gasket therein, a seal cap and a plunger to be engaged with the gasket. The injector is made of a radiation-shielding tubular metal body covered with a plastic material having an exit at the bottom, the body being further provided with a lead glass window on its curved surface, a packing engaging the inside surface at one end of the body and a pair of wings having skid-proof ridges formed on at least one surface thereof, the wings being located at one end of the body. The body is so designed as to be shorter than the tubular portion of the syringe-type vial to be inserted therein, whereby the rear portion of the vial protrudes a little from the tubular body when the same is inserted into the body.

Abstract: A microfilm reader comprises a microfiche moving mechanism for sandwiching a microfiche film between an upper glass plate and a lower glass plate and moving the film in two-dimensional directions, and a projecting optical system for projecting images recorded on the film to a screen. The projecting optical system includes a projecting lens housed in a lens case placed on the upper glass plate of the microfiche moving mechanism. This lens case is raised away from the upper glass plate when the microfiche moving mechanism is in motion. The upper glass plate is raised only when the microfiche moving mechanism is in a home position for inserting and removing the microfiche film to/from a position between the upper and lower glass plates.

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.

Abstract: A micro film reader for projecting by optical devices on a projection surface a selected image recorded in a micro film having a plurality of recording channels in a direction of width of the micro film. The micro film reader has a film carrier for holding and transporting the micro film, a drive motor for shifting the film carrier in the width direction of the micro film, shifting amount setting keys for setting shifting amount of the film carrier, and a channel switching device. The channel switching device controls the drive motor to shift the film carrier by a shifting amount set by means of the shifting amount setting keys. The micro film reader further has a film shifting device for controlling the drive motor to shift the film carrier by a certain amount in response to external signals.
