Patent ID: 7258338

Claim:
A media tray for holding a stack of media comprising: a first tray portion having a first base, an end wall, and two opposing sidewalls flanking the end wall; a second tray portion coupled to said first tray portion, said second tray portion having a second base, and two opposing side guides configured to receive the sidewalls of the first tray portion, the sidewalls of the first tray portion being slidable along the side guides of the second tray portion so as to allow the first tray portion to move relative to the second tray portion to thereby adjust an area for accommodating the stack of media; and a locking mechanism configured to lock the position of the first tray portion relative to the second tray portion at different positions, said locking mechanism comprising: (a) an actuating arm moveably mounted to one sidewall of the first tray portion; (b) a latch moveably coupled to said one sidewall of the first tray portion so as to be moveable between a locking position and an unlocking position; (c) a lever member pivotally mounted to said one sidewall of the first tray portion and configured to link the actuating arm to the latch; (d) an actuator fixedly attached to one end of the actuating arm and positioned adjacent to a corner formed between the end wall and said one sidewall of the first tray portion; and (e) a plurality of spaced-apart notches formed in the second tray portion and configured to engage the latch, wherein the actuating arm is normally spring-biased against the lever member to thereby bias the latch in a locking position, in which the latch engages one of the notches, and the actuating arm is moveable away from the latch upon actuating the actuator to thereby cause the latch to disengage from the notch.
