Abstract
A drive transmitter, including a first rotational axis transmitting a drive force of a drive source to a first rotator, a second rotational axis transmitting a drive force of the drive source to a second rotator, and an idler gear configured to transmit a drive force to the second rotational axis; wherein the first rotational axis penetrates the idler gear with a gap therebetween.
Claims9
A drive transmitter, comprising:
- a first rotational axis configured to transmit a drive force of a drive source to a first rotator;
- a second rotational axis configured to transmit a drive force of the drive source to a second rotator;
- an idler gear configured to transmit a drive force to the second rotational axis;
- a drive transmitting member integrating the first rotational axis;
- a gear engaging with a drive gear of the drive source;
- and
- engaging means formed at an end of the first rotational axis, engaging with the first rotator,
- wherein the first rotational axis penetrates the idler gear with a gap therebetween, and
- wherein a holding member contacts the end of the rotational axis and comprises a regulator regulating movement of the drive transmitting member in an axial direction.
