Abstract: A vehicle body frame of a motorcycle comprises a front frame portion extending rearward from a head pipe, and a rear frame portion extending downward or rearward from a rear end of the front frame portion. The front frame portion includes at least a pair of right and left frame members. A front end of the rear frame portion is welded to a center cross member coupling rear ends of the frame members. The center cross member has a closed cross-section structure in which plate members are joined together in a forward and rearward direction. Thus, a fuel tank and devices can be laid out more flexibly from a location above the center cross member to a location behind the center cross member more flexibly and mounted more easily.

Abstract: In a vehicle body frame including a front frame portion extending rearward from a head pipe, and a rear frame portion extending downward or rearward from a rear end of the front frame portion, a forward portion of the rear frame portion, for example, a lumbar frame, includes a reduced-width portion overlapping with a vehicle body center line extending in a forward and rearward direction when viewed from above, and having a shape in which a width in a rightward and leftward direction is smaller than a length in an upward and downward direction. Devices incorporated into the motorcycle, such as a canister, a battery, an ABS unit, and a suspension unit, are laid out in spaces lateral relative to the reduced-width portion. Thus, the devices can be mounted to the vehicle body frame easily and efficiently.

The front frame portion includes at least a pair of right and left frame members. A forward portion of the rear frame portion is a lumbar frame having a closed cross-section structure portion in which a pair of right and left steel plates and are joined together. Devices such as a canister, and an ABS unit, are easily mounted in spaces lateral relative to the lumbar frame having a reduced width, while ensuring a sufficient stiffness.

Abstract: An ECU controls an adjusting mechanism adjusting an output of an engine, such as a throttle valve, a swirl control valve, an ignition plug, an intake valve, and an ACIS (Acoustic Control Induction System) changing the length of an intake manifold, in accordance with a ratio between a maximum value KL(MAX) of load factor and the load factor required of the engine by the driver and by the system mounted on the vehicle at current engine speed NE.

Abstract: In a toner cartridge, a cover member is attached to an outer surface of a case main body so as to cover a filling hole through which a toner is filled in a toner chamber. The cover member is detachably attached to the case main body by a lock mechanism disposed between the case main body and the cover member. The lock mechanism includes two or more lock structures which lock the cover member to the case main body and a release tool which carries out a release operation of the lock structures. Each of the lock structures includes an elastic engagement claw and an engagement recess which are provided on opposite surfaces of the case main body and the cover member, respectively. The release tool is configured to allow all of the elastic engagement claws to be simultaneously displaced in a lock release direction.

Abstract: A regulating member includes a protrusion protruding from a supporting member toward a developing roller. The length of the supporting member in the longitudinal direction is longer than the length of the protrusion in the longitudinal direction. A seal member includes an extending portion extending from a space for carrying developing agent. The extending portion is turned backward along an end of the regulating member with respect to the longitudinal direction thereof toward the supporting member.

Abstract: An image forming device includes a device main body having a developer receiving port, and a developer discharge unit having a developer discharge port. When the developer discharge unit is attached to the device main body, the developer receiving port and the developer discharge port overlap each other. As the developer discharge unit is attached to the device main body, a shutter opens in a direction that is different from an attaching direction of the developer discharge unit. The developer discharge port of the developer discharge unit is opened accompanying an opening movement of the shutter, and an opening portion of the developer discharge port and an opening portion of the developer receiving port overlap each other at all times.

Abstract: A paddle includes a plurality of axially divided components that are connected together, each component including axially extending blades, wherein the blades overlap with blades provided on a component adjacent to the corresponding component in the circumferential direction.

Abstract: An image forming apparatus for recognizing compatibility of an image forming process unit to be removably mounted at a given position within a main body of the apparatus, includes an engaging member mounting portion arranged to mount a recognition engaging member thereon, and a projecting member mounting portion arranged to mount thereon a recognition projecting member engageable with a recessed portion provided in the recognition engaging member. The projecting member mounting portion and the recognition engaging member mounting portion are respectively capable of mounting the recognition projecting member and recognition engaging member in two or more mounting states. The recognition projecting member and the recognition engaging member are mounted so as to be capable of being engaged with each other in the two or more mounting states so as to achieve compatibility recognition.

Abstract: A developing device includes a sealing member for sealing an end of a developing roller to prevent developer from leaking from the interior of a casing. The casing includes a first plane and a second plane. A blade is mounted to the first plane and the blade regulates the amount of developer on the developing roller. The second plane is positioned upwardly of the first plane. The sealing member is positioned so that an end surface is located between the first plane and the second plane, and is mounted to the casing. The blade is mounted so as to press the end surface of the sealing member.

Abstract: In an image forming apparatus, a second shutter is caused to slide in conjunction with a first shutter which slides in the mounting direction in association with a mounting operation of a developing device to an apparatus body. Accordingly, in association with a separating movement of the developing device from the apparatus body, the first shutter is caused to slide in association with the second shutter which slides in the separating direction, which is the opposite direction from the mounting direction. The direction that the second shutter opens a discharge port is the same direction as the mounting direction. An urging force that a first urging member applies to the first shutter which closes an inlet port is smaller than an urging force that the second urging member is applied to the second shutter which closes the discharge port.
