Abstract: A mounting mechanism provided in a predetermined movable member for mounting an object on the member includes a fixing unit configured to fix the object to the member in drivingly associated with a change in position of the member, and the fixing unit is configured to have a hook with a hook-like end and to rotate the hook in drivingly associated with a change in position of the member so as to fix the object at a predetermined position using the hook-like shape of the hook end.

Abstract: A printing apparatus for printing a paper sheet on a platen by a thermal head with a three color image includes a feeding device and a paper ejecting device. The paper feeding device includes feeding rollers, a feeding tray, a feeding lever and a two-stage discharge bay. With the paper feeding device, a receiving plate for receiving a stack of paper sheets is lifted upwardly toward the feeding rollers so as to keep the leading paper sheet in contact with the feeding rollers; at the same time, a discharged sheet is moved from the first to second discharge stage. The feeding lever is adapted for moving the receiving plate slightly downwardly so as to separate the printing paper sheet from the feeding rollers before the rear edge of the sheet passes under the feeding rollers. Shock is thereby avoided when the leading edge of the sheet passes under the roller.

Abstract: A printing apparatus for printing a paper sheet on a platen by a thermal head with a three color image includes a feeding device and a paper ejecting device. The paper feeding device includes feeding rollers, a feeding tray, and a feeding lever. After printing, the printed paper sheet is ejected forwardly in the printing apparatus by the ejecting device to a stepped discharge plate so as to facilitating removal of the printed paper sheet therefrom.
