Abstract

PURPOSE:To enhance the reliability of the title apparatus wherein slide glass is stored in a slide cassette by a carrier by eliminating the cassette chasing phenomenon of the slide glass easy to generate when a high viscosity liquid is given to the slide glass. CONSTITUTION:A slide glass housing mechanism is constituted of slide glass 1 to which a high viscosity liquid is given, a sample cassette 2, a slide glass rail on which slide glass 1 is transferred, a carrier 4 pushing out the slide glass 1 and a carrier up-and-down mechanism 5. The carrier 4 stores the slide glass 1 in the cassette 2 to set the same at a definite position and, before the carrier 4 begins to turn back, the carrier up-and-down mechanism 5 moves up or down to separate the slide glass 1 and the leading end part of the carrier up-and-down mechanism 5 in a vertical direction. By this constitution, even when the high viscosity liquid 6 is given to the slide glass 1, the slide glass can be stored in the sample cassette 2 at a definite position.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a slide glass storage mechanism, and more particularly to a slide glass storage mechanism suitable for automatic cell analyzers and devices for automatically preparing slide glass specimens.

0002

[Prior Art] In a conventional slide glass storage device, as described in Utility Model Publication No. 38932/1980, the carrier pushes the slide glass and then returns to the horizontal direction. When storing a glass slide with viscous liquid attached to it in a cassette, if the liquid gets between the slide glass and the tip of the carrier, the slide glass will stick to the tip of the carrier and the cassette will follow the carrier. No consideration was given to the possibility that the child would come out of the room.

0003

[Problems to be Solved by the Invention] The above-mentioned prior art takes into consideration adhesion between the slide glass and the extrusion part of the carrier mechanism when a highly viscous liquid such as impregnating oil or blood adheres to the slide glass. If this is not done, the slide glass to be stored may stick to the extrusion part of the carrier and come out of the sample cassette, causing mechanical problems in the operation of the sample cassette and carrier mechanism during the next processing. Ta.

An object of the present invention is to prevent the slide glass from returning from the cassette due to adsorption between the slide glass and the extrusion part of the carrier mechanism.

[0005]

[Means for Solving the Problem] In order to solve the above problem, a carrier mechanism pushes a specimen on a slide glass into a fixed position in a sample cassette, and before starting to return, moves the extrusion part of the carrier up or down to This is achieved by providing a mechanism that vertically separates the extruded portion of the carrier.

[0006]

[Operation] Moving the extrusion part of the carrier upward or downward after pushing the slide glass into the sample cassette and before it begins to return operates to separate the slide glass and the extrusion part of the carrier in the vertical direction. Thereby,
Even if a viscous liquid adheres to the extruded portion of the slide glass and carrier, there will be no problem because the slide glass will not stick to the extruded portion of the carrier and return.
