Abstract: An image forming device having a rotating drum around which an image forming material is trained, an ink sheet conveying mechanism which conveys an ink sheet synchronously with rotation of the rotating drum, an ink transfer device which fits the image forming material and the ink sheet together and effects either heating or pressing such that ink is transferred onto the image forming material, and a fitting/conveying device which moves an image receiving material with respect to a peripheral surface of the rotating drum synchronously with the rotation of the rotating drum and which fits the image forming material and the image receiving material together and applies either a predetermined pressure or a predetermined temperature so that ink is transferred from the image forming material to the image receiving material; and an image forming method including above-described processes. Exposure need be effected only once for each color, and the image forming materials can be used repeatedly.

Abstract: A biochemical analysis apparatus for applying a liquid sample onto a long test film, incubating the sample-applied film portion by an incubator, and measuring the degree of color formation at the sample-applied portion comprises a cutter provided upstream from the position of sample application for cutting the long test film to a length necessary for a single step of sample application, and a cut-film conveyor for conveying the sample-applied and cut portion of the long test film into the incubator, whereby the long test film is utilized efficiently and processing thereof is facilitated.

Abstract: A biochemical analysis apparatus comprises a sample accommodating region, an accommodating region for test films containing a reagent which reacts with a liquid sample to give rise to a change in optical density, and a conveyor for sequentially pulling out each test film from the test film accommodating region. An applicator takes up the liquid sample from the sample accommodating region and applies it to the test film at the position to which the test film has been pulled out. An incubator incubates the sample-applied film portion for a predetermined time, and a detector measures the optical density of the sample-applied film portion during or after the passage of the predetermined time. The conveyor, the incubator and the detector are provided to correspond to each of the test films, and a movement device moves the applicator to apply the liquid sample to the test films.

Abstract: A biochemical analysis method comprises the steps of accommodating a long test film in a refrigerator, repeatedly pulling the long test film out of the refrigerator until a sample-applying portion, i.e., the next unused portion of the test film, is aligned with a sample applying position, applying a liquid samples onto the sample-applying portions of the long test film at which time the sample-applying portions become sample-applied portions, incubating the sample-applied portions, and irradiating light to the sample-applied portions in order to determine optical densities, which depend on the how much of a certain constituent in a liquid sample existed and therefore reacted with a reagent in a reagent layer of the test film. The length of a sample-applying portion to which a present sample will be applied, is changed in accordance with conditions which exist after the analysis of the sample applied to the test film immediately prior to the present sample has been finished.

Abstract: A biochemical analysis apparatus for applying a liquid sample onto a long test film, incubating the sample-applied film portion by an incubator, and measuring the degree of color formation at the sample-applied portion comprises a test film conveyor for continuously conveying at least the part of the long test film inside of the incubator so that a speed v [cm/min.] at which the part of the long test film inside of the incubator is conveyed is expressed as v=n.l. The incubator is constituted so that a length L [cm] of the incubator in the direction of conveyance of the long test film satisfies the condition of L.gtoreq.(nt+1).l, where l [cm] denotes the length of a portion of the long test film necessary for a single step of sample application, t [min.] denotes the incubation time, and n [number/min.] denotes the number of repetitions of sample application per unit time.

Abstract: A long-test-film cassette for biochemical analysis comprises an unused film cassette part accommodating an unused long test film for biochemical analysis, and a used film cassette part for accommodating the long test film which has been pulled out of the unused film cassette part and used for biochemical analysis. A leading edge of the film is secured to a reel in the used film cassette part. In a cassette loading system, the unused film cassette part is provided with a protruded test film outlet portion and is loaded to a refrigerating compartment of an analysis apparatus with the test film outlet portion fitted in a hole of the refrigerating compartment.

Abstract: A biochemical analysis apparatus comprises a slide conveyor for conveying an electrolyte determination slide to a predetermined position, and a sample applicator for taking up and applying a liquid sample and a reference solution onto the electrolyte determination slide conveyed to the predetermined position. An incubator incubates the electrolyte determination slide on which the liquid sample and the reference solution have already been applied, and a measurement device measures a difference in potential between the liquid sample-applied portion and the reference solution-applied portion of the electrolyte determination slide. The sample applicator is provided with a sample applying nozzle used for both the application of the liquid sample and the application of the reference solution. A washing region is provided for washing the sample applying nozzle.

Abstract: A biochemical analysis apparatus comprises a sample accommodating region, a refrigerator for keeping cool a long test film containing a reagent which reacts with a liquid sample to give rise to a change in optical density, and a test film conveyor for sequentially pulling out the long test film from the refrigerator. A sample applicator takes up the liquid sample from the sample accommodating region and applies it to the long test film at the position to which the long test film has been pulled out of the refrigerator. An incubator maintains the sample-applied portion of the long test film at a predetermined temperature for a predetermined time. A detector irradiates light to the sample-applied portion of the long test film, and measures the optical density given rise to by the reaction during or after the passage of the predetermined time.
