<P>PROBLEM TO BE SOLVED: To achieve cost reduction and space saving by reducing the number of components and man-hours required for assembly. <P>SOLUTION: The drive transmission device 100 includes: a drive gear 102 that is driven by a motor; a swing gear 109c that transmits the rotating force of the drive gear 102, applied by the motor, to a drive pulley 105; and a tension roller 109d for applying tension to a transmission belt 104. In addition, the drive transmission device 100 includes: a holder 109a that integrally holds the swing gear 109c and tension roller 109d and is swingable; and an energizing spring 109h that energizes the holder 109a. By swinging the holder 109a by the energizing force of the energizing spring 109h, the swing gear 109c is engaged with the drive gear 102, and the tension roller 109h is brought into firm contact with the transmission belt 104, thereby applying tension to the transmission belt 104. <P>COPYRIGHT: (C)2010,JPO&INPIT |
