Patent ID: 8480076

Claim:
A media handler comprising: a pick unit arranged to receive a media cassette defining a stub; a detent mounted on the pick unit and resiliently biased to protrude into a path traversed by the stub until deflected by the stub; and a latch pivotably mounted to the pick unit and defining (i) a flag portion and (ii) a recess engageable by the stub as the cassette is fully inserted into the pick unit, the latch being moveable between (i) an open position in which the detent prevents the latch from moving and (ii) a closed position in which the detent has been deflected by the stub and the recess engages with the stub, wherein complete insertion of the cassette causes the stub to deflect the detent out of the path, thereby allowing the latch to pivot from the open to the closed position and the recess to engage with the stub to lock the cassette in position; wherein the flag portion is arranged to block a sensor when the latch is moved to the closed position, but not to block the sensor when the latch is in the open position.
