写真装置の駆動伝達機構。 A driven gear disposed on a unit that is removable from the apparatus main body is engaged with a drive gear device disposed in the device main body when the unit is installed, and the driving force of the drive gear device is transferred to the driven gear. In a drive transmission mechanism of an electrophotographic device of the type that transmits power to
The drive gear device includes a drive shaft rotatably supported by a side member of the device body and rotated as appropriate;
a first gear fixed to the drive shaft; a pivot member rotatably supported by the drive shaft about the shaft; and a first gear rotatably supported by the pivot member.
a second gear that rotates while meshing with the gear directly or indirectly, and meshing with the driven gear when the unit is installed.
a gear; and a biasing device that biases the pivoting member so that the second gear can protrude further toward the driven gear than the proper meshing position with the driven gear when the unit is disengaged; It is composed of a regulation hole formed in one of the side member or the pivot member, and a pin protruding from the other and protruding into the regulation hole, and the protrusion range of the second gear is controlled by the cover of the unit to be mounted. A drive transmission mechanism for an electrophotographic apparatus, comprising: a regulating device that regulates a position that allows meshing with a drive gear.
