Samples and dry chemical analysis elements, which are necessary for analyses of the samples, are loaded on a sample tray. Each sample is sucked with a spotting nozzle of a spotting unit and spotted onto one dry chemical analysis element. Analysis information, which contains information representing a type of analysis, is appended to each dry chemical analysis element. The analysis information is read with a reading device located such that, when a certain sample is located at a position for sample suction by an operation of the sample tray, the reading device reads the analysis information, which has been appended to a next dry chemical analysis element to be used for the analysis of the certain sample, at a position at which the next dry chemical analysis element is located.

Biochemical analysis method and apparatus

A slide pack container housing a plurality of piled slide packs has a cut-off portion. The cut-off portion has a width slightly larger than the width of a slide contained in each slide pack. As a sucker of a package take-out apparatus draws one of the slide packs from the slide pack container through the cut-off portion, a sealed portion of the slide pack interfering with the edge of the cut-off portion is folded inward so that the slide pack is successfully taken out. The sucker transfers the slide pack to a separated unwrapping apparatus. The sucker releases the slide pack when the front edge of the slide pack is caught between paired rollers of the unwrapping apparatus. After a cutter makes a slit on the slide pack, the paired rollers transfer only a wrapping sheet to separate the wrapping sheet from the slide wrapped therewith.

Package take-out apparatus, package container thereof and unwrapping apparatus

A dry chemical analysis element cartridge includes a box-like cartridge casing in which a plurality of chemical analysis elements are stacked and are taken out through an element take-out port formed at one end of the cartridge casing. The inner dimension of the cartridge casing in the direction of the stack of the chemical analysis elements is smaller than the longitudinal and transverse dimensions of each of the chemical analysis elements.

An analysis method using a dry chemical analysis element accurately measures change in optical density indicating the composition of a liquid sample without requiring accurate control of the amount and position of the liquid sample dripped on the dry chemical analysis element. A one-dimensional or two-dimensional optical reading apparatus measures one-dimensional or two-dimensional distribution of degree of color reaction for a reacted portion of the dry chemical analysis element. Concurrently, the one-dimensional or two-dimensional optical reading apparatus measures a length or a spread area of the reacted portion. Physical density or activity of a target component contained in the liquid sample is determined based on an integrated value of the degree of the color reaction and the measured length or the spread area of the reacted portion.

Analysis method using dry chemical analysis element

An unwrapping apparatus unwraps a slide pack wrapped with a wrapping sheet to obtain a slide contained therein. As paired rollers forward the slide pack, a squeezing member squeezes the slide backward within an unsealed space in the slide pack to form a wide cut allowance at the front edge of the slide pack. After the slide reaches the rear end of the unsealed space, nip pressure applied to the slide pack by the paired rollers is reduced to further forward the slide pack to a predetermined position. At the predetermined position, a cutter partially cuts the cut allowance to form a slit thereon. Then, the slide pack is transferred back by the paired rollers under a raised nip pressure which is sufficient to squeeze the slide out from the slit. Accordingly, the slide will be gradually separated from the wrapping sheet.

Unwrapping apparatus

A method of supplying a replenishing solution to the processing tank incorporated in an automatic developing machine in which a photosensitive material is processed. In the method, a less active replenishing solution is first supplied to the processing tank at the commencement of the present processing operation of the automatic developing machine prior to our in the course of the processing of the photosensitive material, the less active replenishing solution compensating for the deterioration of a developer due to air during the preceding operating period and the subsequent stop period of the automatic developing machine. A normally active replenishing solution is then supplied to the processing tank after completion of the supply of the less active replenishing solution, the normally active replenishing solution compensating for the deterioration of the developer due to the processing of the photosensitive material. Accordingly, since these replenishing solutions are supplied in this manner, the photosensitive material can be stably developed.

Method of supplying replenishing solution in automatic developing machine

Disclosed is a method of supplying replenishing solution in an automatic developing machine which processes exposed film by means of pump. A time required for the pump to operate is determined using a discharge rate of the pump and a total quantity of replenishing solution to be supplied which is determined in accordance with the amount of exposed film to be processed, and the pump is continuously operated accordingly in that operating time. In consequence, a small size pump can be employed, and the variations in pump discharge rate can be compensated for by controlling the operating time of the pump.
