Printer

A cabinet includes a first area and a second area arranged in a horizontal direction, an image forming apparatus, and a reading device. The image forming apparatus is accommodated in the first area and forms an image on a sheet and ejects the sheet with the image. The reading device is accommodated in the second area of the cabinet and reads an image of a document. At least a part of the reading device is pulled out from an internal space of the cabinet in a direction orthogonal to the horizontal direction in which the first area and the second area are arranged in a horizontal plane.

Cabinet and image forming system

An image forming apparatus includes an exterior housing, an image forming unit in the exterior housing, the image forming unit, to form an image on a sheet, a scanner to read the image on a document, a first region in the exterior housing, the image forming unit being disposed in the first region in view from a front side of the exterior housing, a second region arranged side by side with the first region in a lateral direction in the exterior housing in view from the front side of the exterior housing, the scanner being disposed in the second region, and an opening defining a space in a front face of the exterior housing. The opening extends across the first region and the second region in a lower part of the exterior housing below the image forming unit and the scanner.

Wheel chair accessible image forming apparatus

A drive device, which is included in an image forming apparatus, includes a drive source, a drive switching device configured to switch between a transmission state and a halting state, a first rotary body having a rotary shaft, a first drive transmission passage through which a driving force is transmitted to the first rotary body, a second rotary body, a second drive transmission passage through which the driving force is transmitted to the second rotary body, a drive transmission body rotatably mounted on the rotary shaft of the first rotary body, and an input drive transmission body mounted on the rotary shaft of the first rotary body and configured to input the driving force to the rotary shaft of the first rotary body, the input drive transmission body configured to rotate together with the drive transmission body as a single unit.

Drive device and image forming apparatus incorporating the drive device

A drive transmission device includes a first rotary body coupled to a drive source, a second rotary body that receives a drive force transmitted from the drive source, a coupling that couples the first rotary body and the second rotary body, and a spring that presses the coupling toward the second rotary body. Each of the first rotary body and the second rotary body includes a plurality of grooves. The coupling has axially opposed first end and second end coupled to the first rotary body and the second rotary body, respectively. The coupling includes a plurality of couplers on a circumferential surface of each of the first end and the second end. The plurality of couplers are axially movable into and out of the plurality of grooves of each of the first rotary body and the second rotary body. The coupling has a spherical end face at the second end.
