Abstract
A sheet-handling device includes a tray, two edge guides, an extensile plate and a linkage mechanism. The edge guides and the extensile plate are movably connected to the tray. The linkage mechanism is connected to the edge guides and the extensile plate. When the edge guides or the extensile plate is moved, other components are forced to move via the linkage mechanism.
Claims4
A sheet-handling device, including:
- a tray;
- a first edge guide movably connected to the tray;
- an extensile plate movably connected to the tray;
- a linkage mechanism connected to the first edge guide and the extensile plate, wherein, when the first edge guide is moved, the extensile plate is forced to move by the first edge guide via the linkage mechanism, and when the extensile plate is moved, the first edge guide is forced to move by the extensile plate via the linkage mechanism;
- and,
- a second edge guide connected to the linkage mechanism, by which the second edge guide is also moved when the first edge guide or the extensile plate is moved, wherein the linkage mechanism includes:
- a wheel having a first surface and a second surface;
- a first rod having a first end movably connected to the first surface of the wheel and a second end firmly fixed to the first edge guide;
- a second rod having a third end movably connected to the first surface of the wheel and a fourth end firmly fixed to the second edge guide;
- and
- a third rod having a fifth end movably connected to the second surface of the wheel and a sixth end firmly fixed to the extensile plate.
