A work vehicle includes an operating lever configured to operate a work implement, an actuator configured to move the operating lever, and a control section configured to control the actuator to move the operating lever to a retreat position outside an operation range of the operating lever.

Work vehicle, lever unit, and actuator automatic control method

A camera captures an image of a region including at least a portion of an operating member and generates image data indicative of the image. A controller acquires the image data from the camera. The controller determines whether an operation of the operating member by an operator is an intentional operation or an unintentional operation based on the image. When the operation of the operating member by the operator is determined to be the intentional operation, the controller controls a work machine according to the operation of the operating member. When the operation of the operating member by the operator is determined to be the unintentional operation, the controller invalidates the operation of the operating member.

System and control method for preventing erroneous operation of work machine, and excavator

A work vehicle includes a vehicle main body, a work implement attached to the vehicle main body, an operating lever configured to operate the work implement, an imparting section configured to impart force to the operating lever, an acceleration detection section configured to detect acceleration of the vehicle main body, and a control section configured to control the imparting section to automatically adjust a magnitude of the force imparted to the operating lever based on the acceleration detected by the acceleration detection section.

Work vehicle and method for controlling work vehicle

A development device may include: a development device body; a developer cartridge detachably attached to the development device body; first and second levers provided to the development device body, the first lever including an operation part and a first engagement portion and the second lever including a second engagement portion; first and second engaged portions provided to the developer cartridge, the first engaged portion being configured to form a first engagement with the first engagement portion and the second engaged portion being configured to form a second engagement with the second engagement portion; and a first biasing member biasing the first engagement portion to the first engaged portion. When the operation part is operated with a first pressing force, the first engagement is released, and when the operation part is operated with a second pressing force greater than the first pressing force, the first and second engagements are released.

Development device and image formation apparatus

A developing agent container includes: a container, a shutter that sets a supply hole to a closed state and an open state, a seal sponge that seals a gap between the first surface and the shutter when the supply hole is in the closed state, wherein the shutter has a first ridge line part that makes contact with the seal sponge due to the movement of the shutter, in a first edge part on a front end side in the first direction, the seal sponge has a second ridge line part that makes contact with the shutter due to the movement of the shutter in the first direction, in a second edge part on the opposite direction's side facing the supply hole, and the first ridge line part and the second ridge line part have a relationship in which one is inclined with respect to the other.

Developing agent container with movable shutter for closing developing agent supply hole

An image forming unit includes an image bearing body, a developer storage section that stores a developer removed from a surface of the image bearing body, a frame surrounding the developer storage section, a developer conveying member that conveys the developer in the developer storage section in a predetermined conveying direction, and a convex portion that is provided in the frame and pushes the developer conveying member toward the image bearing body.
