The sheet conveying device included in the image reading device includes an original document conveying device configured to convey an original document having an image on a surface. The sheet conveying device included in the image forming apparatus includes a recording medium conveying device configured to convey the recording medium accommodated in a recording medium container to the image forming device.

An image reading apparatus includes a body support section, an apparatus body supported by the body support section, and a reading section configured to read a document. The apparatus body is configured to rotate about a rotation shaft with respect to the body support section and the apparatus body is rotated to be switched to a first position or a second position, a position of the center of gravity of the apparatus body is located at a position vertically above a shaft axis of the rotation shaft and closer than the shaft axis to an apparatus front in an apparatus depth direction when the apparatus body is in the first position, and is located at a position vertically above the shaft axis of the rotation shaft and closer than the shaft axis to an apparatus rear in the depth direction when the apparatus body is in the second position.

A reading device includes a body having a base on which a read target object is placed, a reader that reads the read target object placed on the base, a first attachment frame to which the reader is attached such that the reader is disposed above the base, an operation unit that is used for operating the device by touching, a second attachment frame to which the operation unit is attached such that the operation unit is disposed above the base and below the reader, and a body frame to which at least the first attachment frame is attached. The first attachment frame includes multiple frame portions extending upward at positions located away from each other.

An optical writing device performs writing by scanning an image surface of a photoconductor with light, and includes a light source unit including a light source that emits light, a deflection unit that deflects and scans the light, an optical element unit for the light, and a housing unit that holds the light source unit, the deflection unit, and the optical element unit. The housing unit includes a vibration isolator that isolates vibration transmitted from a vibration antinode where distribution of vibration in a sub direction perpendicular to a scanning direction of the light on the image surface of the photoconductor is maximum to at least one of seat face parts for the light source unit and the optical element unit having optical sensitivity in the sub direction, in a bottom face part of the housing unit, and a rigidity enhancer that increases rigidity of the seat face part.

An input device and image forming device which can present the user a response by vibration uniformly regardless of the position where the user touches on an operation panel. The input device includes: a vibrating element which vibrates an operation panel unit in at least one direction; a vibration absorbing member which connects the operation panel unit with the device main body and absorbs the vibration of the operation panel unit; and a vibration controller which enables the vibrating element to give a vibration according to the condition in which an operation input is received on the operation panel unit. The vibration controller corrects the amount of vibration in driving the vibrating element by the amount of correction set according to the position where the vibrating element is mounted on the operation panel unit.

A reading device includes: a transparent flat plate with an upper surface on which an object to be read is placed; a reading unit reading information on the object while moving in contact with a transparent flat plate lower surface; a retainer retaining the reading unit by urging the reading unit to be pressed against the lower surface; a guide member supporting and guiding the retainer along a movement direction at a time of reading by the reading unit; and a positioning structural member in at least one end of the reading unit and the retainer in a direction crossing the movement direction to position the reading unit to be maintained being displaceable relative to the retainer in a direction to be closer to and in a direction to be away from the transparent flat plate and being non-displaceable upstream and downstream in the movement direction.

An image forming apparatus includes a frame configured to support a process member configured to execute part of an image formation process on a recording material, a fan placed on a placement surface of the frame so as to be relatively movable with respect to the frame, a duct fixed to the frame and having a communication port communicating with an air intake port or an air outlet port of the fan, a restriction portion configured to restrict a movable range of the fan, and an elastic member disposed to be nipped by the duct and the fan.

An image reading apparatus includes a body support section, an apparatus body supported by the body support section, and a reading section configured to read a document. The apparatus body is configured to rotate about a rotation shaft with respect to the body support section and the apparatus body is rotated to be switched to a first position or a second position, a position of the center of gravity of the apparatus body is located at a position vertically above a shaft axis of the rotation shaft and closer than the shaft axis to an apparatus front in an apparatus depth direction when the apparatus body is in the first position, and is located at a position vertically above the shaft axis of the rotation shaft and closer than the shaft axis to an apparatus rear in the depth direction when the apparatus body is in the second position.

An image reading apparatus includes a reader, a conveying path, a conveyer, a conveyer housing, and a frame. The conveying path guides the sheet having the image to a reading position and guides the sheet read by the reader in an ejecting direction. The conveyer conveys the sheet along the conveying path. The conveyer housing supports the conveying path and the conveyer. The frame comprises columns and beams that connect adjacent columns. The frame individually fixes the reader and the conveyer housing. The columns are provided with resilient conveying-housing fixing members, the conveying-housing fixing members each having a length smaller than the distance between adjacent columns. The conveying-housing fixing members comprise a material having rigidity lower than the material of the beams. The conveyer housing is fixed to the frame by the conveying-housing fixing members. The reader is fixed to the beams.
