ABSTRACT:
A web roll cassette detachably mounted in a printer. The cassette includes a lower case and an upper case having one end pivotally connected to one end of the lower case for selectively providing opening and closing states relative to the lower case. Near the pivot portion, an accommodation space is defined by the upper and lower cases for accommodating therein a web roll. Another end of the upper and lower cases serves as front end discharge portion through which a printed web sheet is discharged out of the cassette. Near the front end discharge portion, the upper and lower cases are formed with through holes where a pinch roller and a drive roller are positioned to nip the web sheet. An opening is formed upstream of the through hole, and a platen is supported on the lower case and exposed at the opening. The drive roller is movable toward and away from the front end discharge portion. After the web roll cassette is inserted into the printer, the web roll cassette is pivotally movable about a position near the one end so that the front end discharge portion is moveable toward and away from the pinch roller.
