<P>PROBLEM TO BE SOLVED: To supply a normally rotating part and a stop type rotating part with rotational motive power by using a single motor and to switch the rotation and stop of the stop type rotating part without using a driving source other than the motor. <P>SOLUTION: First and second driving gears 103 and 104 are connected to the driving shaft 102 of the motor. A first transmission gear 106 is attached to the first driving gear 103 through a first one-direction clutch 105 to transmit the rotational motive power only when the motor is normally rotated and a second transmission gear 111 is also attached to it through a second one-direction clutch 110 to transmit the rotational motive power only when the motor is reversely rotated. A third transmission gear 113 is attached to the second driving gear 104 through a third one-direction clutch 112 to transmit the rotational motive power only when the motor is normally rotated. Gears 108Bk, 108C, 108M and 108Y are rotated when the motor is normally rotated, and only the gear 108Bk is rotated and the gears 108C, 108M and 108Y are stopped when the motor is reversely rotated. <P>COPYRIGHT: (C)2004,JPO&NCIPI |
