摘要： An image reading device includes a housing, a first support member, a reading unit, a movable member, and a flat cable. The housing defines an accommodating space between a bottom surface and a frame member facing the bottom surface. The first support member is supported by the housing and covers the accommodating space. The movable member holds the reading unit disposed in the accommodating space. The flat cable is connected to the reading unit at one end and an electrical part outside the accommodating space at the other end. The housing further includes a support wall protruding from the bottom surface toward the first support member and a cable receiving portion receiving a middle portion of the flat cable. The cable receiving portion is formed at a higher height level than a particular area of the bottom surface located between the support wall and the cable receiving portion.

摘要： A developing device may include an auger or an agitator that is capable of supplying toner in a toner accommodation chamber to a developing chamber and is rotatable about an auger axis extending in an axial direction, a transporting gear that is rotatable together with the auger or the agitator, and a moving gear that is in mesh with a coupling gear and is rotatable both counterclockwise and clockwise. The moving gear is movable while being in mesh with the coupling gear between a first position where the moving gear is in mesh with the transporting gear and a second position where the moving gear is out of mesh with the transporting gear. The moving gear moves to the first position when the coupling gear rotates counterclockwise and to the second position when the coupling gear rotates clockwise.

摘要： An image-forming apparatus includes: a photosensitive drum, a motor, and a drum gear train configured to transmit a driving force from the motor to the photosensitive drum. The drum gear train includes a first gear, a second gear and a first clutch. The first gear is rotatable about a first axis upon receipt of the driving force. The second gear is rotatable about the first axis and configured to receive the driving force from the first gear and to transmit the driving force to the photosensitive drum. The first clutch is switchable between a first transmission state where the driving force is transmitted from the first gear to the second gear and a first transmission cutoff state where the transmission of the driving force from the first gear to the second gear is cut off.
