A positioning structure includes a locking member fixed on the outer casing, and a support member for immobilizing the locking member with respect to the outer casing in such a manner that the locking member extends upwardly into the outer casing to prevent movement of the tray with respect to the outer casing. A protrusion portion of the outer casing surrounding the locking member and extending in the moving direction defines the support member.

Abstract: A tilt adjustment device for adjusting tilt of a left guide bar with respect to a right guide bar, and includes a holding seat and a cylindrical-shaped bushing disposed rotatably within the holding seat. The bushing defines a bar-retention hole to permit extension of the left guide bar therethrough, and has a turning portion defining a first axis and an insert portion that extends eccentrically from the turning portion and that defines a second axis parallel to the first axis. Rotation of the cylindrical-shaped bushing relative to the holding seat results in a radial movement of the turning portion, which, in turn, moves the first axis toward and away from the second axis of the insert portion.
