摘要： A driving device for driving a driving member includes a driving source; a driving gear fixed to a rotation shaft of the driving source; at least one gear for transmitting rotational motion of the driving gear to the driven member; a rotation detection gear engaged with the at least one gear; a detector for detecting rotation of the rotation detection gear; and a controller for detecting an angular speed and a rotational phase of the rotation detection gear on the basis of information from the detector and for controlling the rotational speed of the driving source such that a rotation period of the rotation detection gear is a non-integer multiple of a rotation period of the driving gear.

摘要： A driving device includes a motor including a rotating shaft, a drive transmission member attached to the rotating shaft and including a contact portion, and a drive output member including a contacted portion with which the contact portion comes into contact, and configured to be rotated around the rotating shaft when the rotating shaft of the motor is driven and the drive transmission member is rotated together with the rotation shaft in a first direction. The drive transmission member further includes an engaging portion. The drive output member includes an engaged portion with which the engaging portion is to be engaged when the drive output member is rotated relative to the drive transmission member in a second direction opposite to the first direction. A driving force is transmittable to the drive output member whether the drive transmission member is rotated in the first direction or the second direction.

摘要： A driving force transmitting apparatus includes first and second planetary gear units and switching and urging members. The first planetary gear unit includes a first mesh gear and a first locked gear provided with first locked portions. The second planetary gear unit includes a second locked gear provided with second locked portions, and a second mesh gear meshing with the first mesh gear. The switching member includes first and second locking portions and can move to (i) a first stop position at which the first locking portion stop the first locked gear, and, urged by the urging member, (ii) a second stop position at which the second locking portion stops the second locked gear. An interval between the second locked portions in a rotational direction of the second locked gear is larger than an interval between the first locked portions in a rotational direction of the first locked gear.

摘要： An image forming apparatus includes an apparatus body including a mounting portion, a drive transmission member provided on the apparatus body, and a cover portion configured to cover the drive transmission member. The mounting portion is configured to accommodate a cartridge including an input coupling portion and an input gear portion. The drive transmission member includes an output coupling portion configured to engage with the input coupling portion, and an output gear portion configured to engage with the input gear portion. The cover portion is located between the mounting portion and the drive transmission member and includes a first opening configured to expose the output coupling portion, and a second opening configured to expose the output gear portion.
