CASSETTE AND DELIVERY SYSTEM

摘要

PURPOSE: A cassette and a delivery system are provided to produce a sleeve easily and to reduce the cost of the sleeve by using a single-layer sleeve. CONSTITUTION: A cassette(14) is received within a sleeve(16) having an open end. Specially folded flaps at the open end are applied to center the cassette in the sleeve and to reduce a width of the open end of the sleeve. Thereby, the outer sizes of the cassette and the sleeve are equalized for each system though the sleeves of different thickness are used.
