<P>PROBLEM TO BE SOLVED: To provide a compact motor device. <P>SOLUTION: The motor device includes: a rotor SF having an outer circumference SFa or inner circumference formed about a first axis C and rotatable about the first axis; transmission members RG1, RG2 having inner circumferences 21b, 31b or outer circumferences formed about a second axis C2 so as to oppose the outer circumference or inner circumference of the rotor at a predetermined gap when the second axis is positioned coaxially or in parallel with the first axis and to partly abut the outer circumference or inner circumference of the rotor when the second axis is positioned across the first axis; a plurality of drive parts 41, 43 connected to the transmission members to move the transmission members to positions where the second axis crosses the first axis to develop a rotation force transmission state between the rotor and the transmission members; and a control section CONT for instructing the drive parts to perform a transmitting operation of moving the transmission members to positions to develop the rotation force transmission state and an eliminating operation of moving the transmission members to positions to eliminate the rotation force transmission state. <P>COPYRIGHT: (C)2012,JPO&INPIT |
