<p>A tape cassette for use in a printing device. The cassette is preferably formed of two planar walls (612, 614) and bounded by a peripheral wall (616). A portion of the peripheral wall has a slot (632) from which indicator (640) can be seen. The indicator (640) is preferably curved so that it rides upon the outer curvature of the spool (638). A bias device (646) biases the indicator against the spool to maintain a readout. A portion of the peripheral wall (616a) is preferably curved to approximate the trace of the distant end of the indicator (640) to maintain a constant readout.</p> |
