    Patent number: 6832734
    Abstract: A media discharge device includes a support member, a telescoping device supported by the support member, and a media discharge port provided at a first end of the telescoping device. The telescoping device is supported via a joint structure that allows the telescoping device to rotate with respect to the support member with at least one degree of freedom. The telescoping device includes a first member and a second member that moves with respect to the first member in an extending direction and a retracting direction. An actuator may drive the second member in the extending direction and in the retracting direction.
