Patent ID: RE43022

Claim:
A tape cassette for use with a printing device that includes a tape drive, pins, a print head, an array of sensors, and a drive shaft, the tape cassette comprising: printing tape; and a cassette casing housing the printing tape and defining four corners and a feed path through which the printing 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 defining a recess to receive the drive shaft adjacent a first corner of the four corners of the cassette casing downstream of, and spaced from, the head recess in the feeding direction and adapted to engage the tape drive of the printing device to feed the printing tape in the feeding direction, the cassette casing defining a first positioning hole adjacent the drive shaft and a second positioning hole spaced from the drive shaft, the first and second positioning holes communicating with the pins of the printing device to ensure a proper positioning of the cassette casing within the printing device, the cassette casing defining a detector surface adapted to interact with the array of sensors of the printing device to identify at least one characteristic of the tape cassette, the detector surface positioned absolutely at a second corner of the four corners, the second corner positioned diagonally opposite the first corner, the detector surface defining multiple sensor holes that interact with the array of sensors of the printing device.
