<P>PROBLEM TO BE SOLVED: To provide a drive transmission device capable of achieving miniaturization, reduction of the cost, reduction of a rate of incidence of failure, and transmission of stable driving force, and an image forming device equipped with the drive transmission device. <P>SOLUTION: This drive transmission device is provided with an oscillating gear 110 driven by a driving gear 109a and capable of moving to a first position and a second position by forward/backward rotation of the driving gear 109a, a first gear train 111B of which linkage with the oscillating gear 110 is released in a first position of the oscillating gear 110 and linked with the oscillating gear 110 in a second position, and a first driven part 101 operated by power of a drive source transmitted through the first gear train 111B. Regulating means 118b and 120 for regulating an oscillating gear holding member 118 is provided so that the oscillating gear 110 cannot be moved to the direction where linkage between the first gear train 111B driving the driven part 101 and the oscillating gear 110 is released during driving of the first driven part 101. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
