An image forming apparatus includes a pair of side walls disposed opposite each other; a driven unit supported between the side walls; a drive unit with drive transmission gears attached to one of the side walls and drives the driven unit; and a reinforcing member connecting the pair of side walls. One end of the reinforcing member is attached to the side wall opposite the other side wall to which the drive unit is attached and the other end is attached to the drive unit. The driven unit is an image forming unit including at least an image carrier. The image carrier includes a rotary shaft, both lateral ends of which are supported by the pair of side walls. A gear portion engaging the drive transmission gears of the drive unit is disposed on one end of the rotary shaft of the image carrier.

A power supply device to electroconductively connect a power-fed terminal included in a power-fed unit and a power supply terminal of a power supply board. The power supply device includes a unit contact portion to contact the power-fed terminal; a board contact portion to contact the power supply board; a connector to connect the unit contact portion and the board contact portion; and a support member to support the unit contact portion, the board contact portion, and the connector. The unit contact portion is held on an inner face of the support member opposed to the power-fed unit; the board contact portion is held on an outer face of the support member opposed to the power supply board; and the connector connects the unit contact portion and the board contact portion through the support member.

An image forming apparatus includes an outer cover in which an air intake and an exhaust outlet are formed, an image forming unit, a fixing device to fix an image on a recording medium and including a fixing casing in which a sheet inlet and a first exhaust opening are formed, and a thermal shield disposed above the sheet inlet of the fixing device and between the fixing device and a component adjacent to the fixing device, an air channel to guide air sucked in through the air intake to the exhaust outlet, defined by the thermal shield as well as the fixing casing. The first exhaust opening formed in the fixing casing communicates with the air channel formed by the thermal shield and the fixing casing to merge the hot air discharged from the fixing device into the air flowing in the air channel.

An image forming apparatus includes an exposure device as a light source, a developer container storing developer and attached to a main body of the image forming apparatus perpendicular to a lengthwise direction of the photoconductor, a developing unit and a photoconductor unit having a photoconductor for bearing a latent image thereon each detachably attached to the main body substantially in the same direction as the developer container. An exposure device displacing mechanism displaces the exposure device between a first position enabling the exposure device to function as the light source and a second position disabling the exposure device to function as the light source. The photoconductor unit is detached when the developer container is either displaced from an initially attached position or is removed from the main body and the exposure device displacing device has displaced the exposure device to the second position.

An interlock system includes first and second racks movable in parallel to each other in a longitudinal direction between opening and closing positions in conjunction with opening and closing of the first cover, respectively. A housing is provided to slidably accommodate the first and second racks in the longitudinal direction. A pinion unit is provided and is sandwiched by the first and second racks. The first and second racks have meshing sections respectively meshing with the pinion unit at one side surfaces extending in the longitudinal direction facing each other. The pinion unit slides in the longitudinal direction by a prescribed length in conjunction with movement of at least one of the first and second racks. The interlock switch is turned on and off in accordance with a sliding length of the pinion unit in the longitudinal direction.

A life estimation device which numerically measures the damage to a machine such as an engine accurately to estimate, the life of the machine accurately without requiring skill. A load map (B) of the two-dimensional distribution of the operation parameters of an engine is made. In accordance with the weighted integration time &agr;i·ki at each level (Bi) of the load map (B), the actual damage &dgr;=&Sgr;&agr;i·ki to the engine for a certain lapse of time &tgr; is calculated. By operating the engine beforehand, a correspondence relation L2 between the magnitude of the damage &dgr; and the life H is predetermined. The life H1 corresponding to the calculated actual damage &dgr;1 is determined in accordance with the predetermined correspondence relation L2 and the H1 is outputted as the estimated life of the engine.

The governor device includes an electromagnetic clutch capable of utilizing the driving force of a diesel engine for driving a control rack of fuel injection pumps. The electromagnetic clutch is controlled based on the difference between a preset engine speed and an actual speed. With this device, electrically controlled governor operation can be executed without use of an electric actuator such as a solenoid or the like.

An apparatus body includes a housing, a drawer, a push-out mechanism, and a positioner. The drawer is attachable to and detachable from the housing. The push-out mechanism pushes out the drawer by a predetermined amount from a setting position at which the drawer is positioned in the housing. The positioner positions the drawer at the setting position in the housing. The positioner includes a fitting hole disposed in one of the housing and the drawer and a positioning pin disposed in the other of the housing and the drawer. The positioning pin positions the drawer at the setting position in the housing in response to fitting of the positioning pin into the fitting hole. The positioning pin and the fitting hole each have a form that releases the fitting in response to pushing out of the drawer by the predetermined amount from the setting position.
摘要:
An image forming apparatus capable of preventing the image formation unit from being attached to a guide member for the image formation unit mistakenly, including an apparatus body; an image carrier including a rotary shaft; an exposure device configured to form a latent image through exposure of a surface of the image carrier and retractable from an exposure position; an image formation unit disposed detachably from the apparatus body; and a guide member to guide the exposure device to the exposure position. In the optimal apparatus, the guide member is used both to guide the image formation unit to the apparatus body and to guide the exposure device to the exposure position.
