Cassette for storing sheet media

Abstract

A cassette for storing sheet media includes a box body with an opening, wherein the cassette further includes a pressing plate located in the box body, and a self-driven mechanism for driving the pressing plate to move towards the opening; the self-driven mechanism includes a support frame connected with the pressing plate, a driving shaft arranged on the support frame and driven by an elastic energy storage element, travelling gears synchronously moving on the two sides of the support frame, and guide racks matched with the travelling gears and extending along a stacking direction of the sheet media; and the travelling gears are driven by the driving shaft.

Description

[0001]This disclosure claims the priority of Chinese patent application No. 201210457222.7, entitled “cassette for storing sheet medium” filed with the State Intellectual Property Office on Nov. 14, 2012, the entire contents of which are incorporated herein by reference.TECHNICAL FIELD OF THE DISCLOSURE[0002]The disclosure relates to a cassette for storing sheet media.BACKGROUND OF THE DISCLOSURE[0003]The self-service equipment, such as an automatic teller machine and a self-service card issuing machine, is provided with a cassette for storing sheet media such as banknotes or cards, wherein a pressing plate for stacking the sheet media and a driving mechanism for driving the pressing plate to elastically press the sheet media towards an opening of the cassette are arranged in the cassette, and when the sheet media continuously enter the cassette or are continuously discharged from the cassette, the pressing plate, under the driving of the driving mechanism, can always press the shee...

AI Technical Summary

Benefits of technology

The disclosed cassette provides a self-driven mechanism for the pressing plate, which improves its movement reliability. The mechanism includes a driving shaft, elastic energy storage element, and traveling gears, which work together with guide racks to ensure stable movement of the pressing plate without inclination. The accumulated energy is released when no external force is applied, allowing the pressing plate to move close to the opening of the cassette.

Problems solved by technology

The pressing plate driving mechanism has a problem that the lead screw 5′ for driving the pressing plate 2′ to move is located on a single side of the pressing plate 2′ and the pressing plate 2′ is easily inclined relative to the lead screw 5′ to increase transmission resistance between the nut 9′ and the lead screw 5′ when the sheet media stacked on the pressing plate 2′ are heavier, so that noise during the movement of the pressing plate 2′ is increased, and relative movement between the nut 9′ and the lead screw 5′ may be hindered to cause that the pressing plate 2′ cannot move smoothly and lower movement reliability.
