Abstract
A recording medium feeding device including: a feeding member that feeds a recording medium; a plate on which the recording medium is placed; a power outputting section that outputs a power for elevating the plate in a direction of pressing the recording medium against the feeding member; and a power transmitting section that transmits the power outputted from the power outputting section to the plate, the power transmitting section being adapted so as not to transmit the power to the plate, when a repulsive force against the power for elevating the plate is larger than a predetermined value.
Claims11
A recording medium feeding device comprising:
- a feeding member that feeds a recording medium;
- a plate on which the recording medium is placed;
- a power outputting section that outputs a power for elevating the plate in a direction of pressing the recording medium against the feeding member;
- and
- a power transmitting section that transmits the power outputted from the power outputting section to the plate, the power transmitting section being adapted so as not to transmit the power to the plate, when a repulsive force against the power for elevating the plate is larger than a predetermined value.
An image forming apparatus comprising:
- a recording medium feeding device that comprises:
- a feeding member that feeds a recording medium;
- a plate on which the recording medium is placed;
- a power outputting section that outputs a power for elevating the plate in a direction of pressing the recording medium against the feeding member;
- and
- a power transmitting section that transmits the power outputted from the power outputting section to the plate, the power transmitting section being adapted so as not to transmit the power to the plate, when a repulsive force against the power for elevating the plate is larger than a predetermined value.
A recording medium feeding device comprising:
- a feeding member that feeds a recording medium;
- a plate on which the recording medium is placed;
- a plate urging member that urges the plate in an elevating direction;
- a power outputting section that outputs a power for elevating the plate;
- and
- a power transmitting section that transmits the power outputted from the power outputting section to the plate, the power transmitting section being configured to stop transmission of the power.
