Tape-shaped label printing device

A tape cassette for a printing device having a drive shaft, a print head with a printing region, and a platen roller supported on a roller support arm that is pivotally attached to the tape printer to allow the platen roller to pivot toward and away from the print head, the tape cassette comprising:

• a cassette casing comprising upper and lower surfaces and a lateral surface extending between the upper and lower surfaces, the cassette casing housing a printing tape and defining a feed path through which the tape moves in a feeding direction, the cassette casing defining a head recess adapted to receive the print head of the printing device;
• the cassette casing further including a support hole adjacent a first corner of the cassette casing downstream of the head recess in the feed direction and adapted to receive the tape drive of the printing device to feed the tape in the feeding direction;
• and tape guides upstream of the head recess for guiding the tape in the feeding direction, the tape guides extending from a second corner of the cassette casing diagonally opposite the first corner toward a third corner located between the first and second corners in the feed direction;
• and
• a recess located in the lateral wall between the first and third corners for receiving the pivot section of the roller support arm, the recess having a depth that receives the pivot section to allow the roller support arm to be parallel to the print head when the platen roller presses the tape against the print head.

A tape cassette for a tape printer having a drive shaft, a print head having a printing region, and a platen roller supported on a roller support arm that is pivotally attached to the tape printer to allow the platen roller to pivot toward and away from the print head, the tape cassette comprising:

• a cassette housing sized for mounting within the tape printer;
• a head recess in the cassette housing for receiving the print head when the cassette housing is inserted within the tape printer;
• a tape spool rotatably supported within the cassette housing;
• a tape wound on the tape spool for feeding the tape to the printing region;
• a support hole downstream of the head recess for receiving the drive shaft of the tape printer;
• an arm portion formed in the cassette housing adjacent the head recess for directing tape from the tape spool toward the printing region;
• and
• a recess located in the arm portion of the housing for receiving the pivot section of the roller support arm, the roller support arm pivoting the platen roller to press the tape against the print head, the tape being pressed against the print head by the platen roller so that the tape is parallel to the print head before the tape enters the printing region, the recess having a depth that receives the pivot section to allow the roller support arm to be parallel to the print head when the platen roller presses the tape against the print head.

• and
• a recess located in the arm portion of the housing for receiving the pivot section of the roller support arm, the roller support arm pivoting the platen roller to press the tape against the print head, wherein a line between a rotational axis of the pivot section of the roller support arm and a rotational axis of the platen roller is substantially parallel to the print head when the tape cassette is mounted within the tape printer, the recess having a depth that receives the pivot section to allow the roller support arm to be parallel to the print head when the platen roller presses the tape against the print head.
