Patent ID: 7413362

Claim:
A paper tray for a printer, comprising: a paper support plate that is adapted to support either a sheet of paper to be fed through a paper inlet formed in a printer body or a sheet of paper ejected through a paper outlet formed in the printer body and that has a C-shaped hook having upper and lower arms to be open at one side of the hook; and a support frame that is formed on a housing of the printer body adjacent the paper inlet or the paper outlet and that has a protruding shaft and a housing wall, wherein the paper support plate is hinged to the support frame with the C-shaped hook engaged with the protruding shaft on the support frame so that the paper support plate can be rotated between a vertical position where the paper support plate is folded to be substantially parallel to a face of the printer body and a horizontal position where the paper support plate projects in a direction substantially perpendicular to the face of the printer body, wherein the housing wall has an extending portion extending forward beyond the protruding shaft, the extending portion having a top surface serving as a contact surface to contact the C-shaped hook, and the C-shaped hook has a contact surface to face the top surface of the extending portion at a position opposite to the open side, so that rotation of the paper support plate to the horizontal position is limited by the contact surface of the C-shaped hook coming in contact with the top surface of the extending portion.
