Abstract
A print-medium storing unit, a print-medium storing apparatus including the same, and an image forming apparatus including the same which are provided in a power transmission mechanism, print-medium storing apparatus which is installed on a discharge path of a print-medium in an image forming apparatus, includes a plurality of storing units which is arranged with multi-layers, and a controller which controls to drive a feeding unit of another storing unit arranged between the storing unit through which the print-medium is to be discharged and the image forming apparatus, by a driving source of the storing unit through which the print-medium is to be discharged.
Claims7
A print-medium storing apparatus which is installed on a discharge path of a print-medium in an image forming apparatus, comprising:
- a plurality of storing units which are arranged with a multi-layer configuration;
- a controller to control a drive of a feeding unit of a storing unit arranged between another storing unit through which the print-medium is to be discharged and the image forming apparatus, by controlling a second driving source of the another storing unit through which the print-medium is to be discharged;
- and
- a power transmission unit which transmits a driving force of a first driving source to the feeding unit including:
- a plurality of gears which transmit the driving force of the first driving source;
- a first power switching unit which transmits the driving force of the first driving source connected thereto to the plurality of gears and the feeding unit, and prevents a second driving force of the second driving source of the another storing unit from being transmitted to a discharging roller connected to the storing unit;
- and
- a second power switching unit disposed on a shaft which transmits a driving force of the second driving source of the another storing unit via a first gear mounted on the shaft to a feeding roller of the storing unit, and prevents the driving force of the storing unit from being transmitted from a second gear mounted on the shaft to the first gear and to the another storing unit.
A print-medium storing unit, comprising:
- a tray on which a print-medium is stored;
- a driving source which provides a driving force;
- a feeding unit which comprises a feeding roller which feeds the print-medium, and a discharging roller which discharges the print-medium fed through the feeding roller to the tray;
- and
- a power transmission unit which transmits the driving force of the driving source to the feeding unit, the power transmission unit comprising:
- a first power switching unit which transmits the driving force of the driving source connected thereto to the feeding unit, and prevents a second driving force of a second driving source of an upper-layered storing unit from being transmitted to the discharging roller connected thereto;
- and
- a second power switching unit disposed on a shaft which transmits a driving force of the second driving source of the upper-layered storing unit via a first gear mounted on the shaft to a feeding roller of a lower-layered storing unit, and prevents the driving force of the lower-layered storing unit from being transmitted from a second gear mounted on the shaft to the first gear and to the upper-layered storing unit.
