PURPOSE: To contrive the simplification of an electronic component chip handling device, such as a chip mounting machine or the like, by a method wherein a cassette is provided with a plurality of electronic component chips and a case, in which the chips are housed in an alignment state that they are each turned in a prescribed direction and which is provided with a plurality of parallelized housing spaces in its interior and is designed openably to one direction of the housing spaces.

CONSTITUTION: A cassette 1 is provided with a case 4, which is provided with housing spaces 3 for housing a plurality of electronic component chips 2 in an alignment state that the chips 2 are each turned in a prescribed direction in its interior. The case 4 is provided with a case main body 5 and a cover 6 which is combined with the main body 5 in a fitting manner. A plurality of parallelized grooves 7 which are used as the spaces 3 are formed in the main body 5 an when the cover 6 is combined with the main body 5, openings in the upper surface, which is located on the grooves 7, of the cover 6 are closed and the grooves 7 are used as a plurality of the parallelized spaces 3. The cover 6 is provided with rise parts 8 and 9, by which when the cover 6 is combined with the main body 5, both ends of the spaces 3 are respectively closed, and is fitted in the main body 5. Thereby, the cover 6 is slidingly used to the main body 5 in the directions to intersect orthogonally to the extension directions of the spaces 3.
