摘要： An image forming apparatus including a medium storage portion, a supply roller, a conveyance roller, a drive device and a transmission device is provided. The supply roller is rotary driven in a forward direction as a rotating direction to convey the recording mediums to a position for image formation, thereby to supply the abutting uppermost recording medium to a conveyance path. The conveyance roller is rotary driven in a forward direction as a rotating direction to convey the recording mediums to a position for image formation, thereby to allow passage of the uppermost recording medium conveyed by the supply roller. In the image forming apparatus, a conveyance speed of the recording medium by the conveyance roller is adapted to be faster than a conveyance speed of the recording medium by the supply roller.

摘要： A printer having a switch gear, first driven gear and second driven gear. The switch gear has a spur gear and is slidable along a direction that is parallel to a rotation axis of the spur gear. The first driven gear has a first spur gear and a cylinder fixed to the first spur gear. The cylinder is concentric with respect to the first spur gear and extends along the above direction. A hole is formed on the second driven gear. The hole is concentric with respect to a second spur gear and extends along the above direction. The second driven gear is rotatably mounted on the first driven gear by inserting the cylinder of the first driven gear into the hole of the second driven gear. The switch gear slides between a first position for engagement with the first driven gear and a second position for engagement with the second driven gear along the above direction. Since the driven gears are formed in this way, the position of the first driven gear in the above direction is not changed even when the second driven gear is not provided.

摘要： A printer is equipped with a supply roller for sending a piece of sheet from pieces of sheets stacked within a cassette; a pair of feed-in rollers for sending the piece of sheet supplied from the supply roller toward a printing region; and a sheet sensor provided between the supply roller and the pair of feed-in roller. The printer rotates the pair of feed-in rollers in a forward direction in a case that the sheet sensor detects presence of the sheet at a timing when it is found that printing data for a subsequent sheet is not stored within the printer. On the other hand, the printer rotates the supply roller in a reward direction when the sheet sensor detects non-presence of the sheet at the timing when it is found that the printing data for the subsequent sheet is not stored within the printer.

摘要： A feeding roller is rotatable about an imaginary rotational axis extending in an axial direction and is configured to be rotatingly driven in a rotational direction for feeding a recording medium to a conveying path. A supporting section rotatably supports the feeding roller at a position in confrontation with the recording medium accommodated in a recording-medium accommodating section. A driving unit is configured to generate a rotational driving force. A transmitting unit is configured to transmit the rotational driving force to a central part of the feeding roller with respect to the axial direction. A guiding section prevents the recording medium accommodated in the recording-medium accommodating section from displacing in the axial direction. The supporting section rotatably supports the feeding roller in such a manner that an angle of the imaginary rotational axis relative to a reference direction can be changed by a predetermined amount.

摘要： This invention is related to a feeder for transporting a print medium from a tray along a U-shaped transporting path. The feeder includes a movement member coupled to a feeding roller. The movement member includes a first portion located at a position such that the print medium makes contact with the first portion when a transporting roller and the feeding roller simultaneously make contact with the print medium. The first portion receives a force from the print medium when the first print medium makes contact with the first portion. The movement member moves the feeding roller by utilizing the force such that a distance between the feeding roller and the support surface of the tray increases.
