Claim of US Patent No. 10,462,325

1. An image reading apparatus comprising:a first imaging device secured to the image reading apparatus;
a second imaging device movably provided between a first position facing the first imaging device and a second position facing the first imaging device, wherein the second position is at a longer distance from the first imaging device than the first position;
a guide for guiding a document between the first imaging device and the second imaging device;
an image capturing device provided on one of the first imaging device and the second imaging device for capturing an image of the document guided by the guide;
a drive force generating device for generating a first drive force for moving the second imaging device by a rotation in a first direction and generating a second drive force by a rotation in a second direction opposite to the first direction;
a conveyance roller;
a drive force transmitter arranged between the drive force generating device, and the second imaging device and the conveyance roller; and
a processor configured to cause the drive force generating device to generate the first drive force when the document is not conveyed, wherein
the drive force transmitter
transmits the first drive force to the second imaging device to move the second imaging device, and
transmits the second drive force to the conveyance roller to convey the document and interrupts transmission of the second drive force to the second imaging device in response to a switching from the first drive force to the second drive force.
