An item fixture, a handle, a method of attaching a measuring apparatus to a vehicle, and a mobile measuring apparatus. The item fixture includes a fixation member to be attached to an attachment portion of a vehicle, and a handle attachment portion to which a handle used to attach the item fixture to the vehicle is to be detachably attached. The method of attaching a measuring apparatus to the vehicle includes attaching a pair of handles to an item fixture of the measuring apparatus, attaching the item fixture to an attachment portion of the vehicle, using the pair of handles as a handle of the item fixture, and detaching the pair of handles from the item fixture. The mobile measuring apparatus includes the vehicle, the item fixture attached to the vehicle, and a measuring device attached to the item fixture.

Item fixture, handle, method of attaching measuring apparatus to vehicle, and mobile measuring apparatus

An article attaching device to be attached to an apparatus including a movable member includes a holder configured to hold an article, a base to be secured to the apparatus, and a rotator to support the holder on the base. The rotator supports the holder to rotate in conjunction with a movement of the movable member.

Article attaching device and measuring system

A measurement apparatus mountable on a movable apparatus includes a first imaging device to capture an image in a first image capture direction, the first image capture direction having a first angle with respect to a direction of travel of the movable apparatus, and a second imaging device disposed next to the first imaging device to capture an image in a second image capture direction, the second image capture direction having a second angle with respect to the direction of travel of the movable apparatus. The first and second imaging devices are disposed to overlap at least partially a first imaging range of the first imaging device and a second imaging range of the second imaging device. At least one of the first image capture direction of the first imaging device and the second image capture direction of the second imaging device is set at a given angle with respect to a width dimension of the movable apparatus.

Measurement apparatus, movable apparatus, and vehicle

A toner cartridge include a convex portion and a conveyance drive gear. There is a protrusion which protrudes from the center of the conveyance drive gear. Further, there is a hole at a rear side of the convex portion. The protrusion is to be inserted into the hole which is at the rear side of the convex portion.

A measurement apparatus () mountable on a movable apparatus () includes a first imaging device (-) configured to capture an image in a first image capture direction, the first image capture direction having a first angle with respect to a direction of travel of the movable apparatus (), and a second imaging device (-) disposed next to the first imaging device (-) configured to capture an image in a second image capture direction, the second image capture direction having a second angle with respect to the direction of travel of the movable apparatus (). The first imaging device (-) and the second imaging device (-) are disposed to overlap at least partially a first imaging range of the first imaging device (-) and a second imaging range of the second imaging device (-). At least one of the first image capture direction of the first imaging device (-) and the second image capture direction of the second imaging device (-) is set at a given angle with respect to a width dimension of the movable apparatus ().

A removable device detachably attachable to a receiving structure includes a convex to be inserted into a groove of the receiving structure, a rotator to rotate around a rotational shaft, a recess at a rear side of the convex, a gear attached to the rotational shaft, and a gear cover to cover at least a part of the gear. Further, an end of the rotational shaft is inserted into the recess, part of the gear is exposed from the gear cover, and a peripheral of the end of the rotational shaft is surrounded by the gear cover.

Developer container for image forming apparatus

The developer container includes a rotator that is rotated in the container body, a sequence of gears disposed outside the developer container that transmits a torque to the rotator, and a container guiding portion that fits with a main body side guiding portion and guides the developer container in a direction in which the developer container is attached to a mounting portion of an image forming device main body. A first gear included in the sequence of the gears is movable between an operating position where the first gear engages with a second gear and a retracted position where the first gear is retracted. On a surface on which the container guiding portion is disposed, a part of the container guiding portion is disposed within a projected area of the first gear being disposed at the operating position.

Downsized developer container with higher degree of freedom

A removable device is to be detachably attached to an apparatus main body. The removable device includes a conveying drive gear attached to a first rotational shaft, an agitating drive gear attached to a second rotational shaft, and a torque transmission gear attached to a third rotational shaft. When an addendum circle diameter of the conveying drive gear is A, and an addendum circle diameter of the agitating drive gear is B, B&#x3e;A is satisfied. The torque transmission gear moves around the conveying drive gear to access the agitating drive gear.

Developer container, developing device, process unit, and image forming apparatus

Toner container

A removable developer container includes a convex portion to be inserted into a groove of an apparatus main body, a rotator to rotate around a rotational shaft, and a recess convex portion to be inserted into a groove of an apparatus main body, at a rear side of the convex portion. One end of the rotational shaft is inserted into the recess.

Developer container including a convex portion, a rotator, and a recess

A removable device to be detachably attached to an apparatus main body includes a container body to store developer; a discharge opening to discharge the developer inside the container body; an internal shutter to open and close the discharge opening; an external shutter to open and close the discharge opening, the external shutter being disposed at an outer side with respect to the internal shutter, wherein the internal shutter and the external shutter are configured to be driven separately.

A developing device includes a development unit, a developer amount detector, an accuracy requirement determiner, and a detection count setting unit. The development unit includes a developer container configured to store a developer. The development unit is configured to supply the developer from the developer container to a latent image bearer, on which an electrostatic latent image is to be formed according to image data, to form a developer image. The developer amount detector is configured to detect a developer amount in the toner container of the development unit in every detection period. The accuracy requirement determiner is configured to a determine accuracy requirement required as a detection accuracy of the developer amount by the developer amount detector. The detection count setting unit is configured to set a number of times of detection of the developer amount by the developer amount detector based on the accuracy requirement.

Developing device, image forming apparatus, method of detecting developer amount, and non-transitory recording medium storing program

A powder container is provided. The powder container includes a powder storage and a conveyer. The powder storage stores a powder to be used for image formation and has a vent hole to pass air between an inside and an outside of the powder storage. The conveyer conveys the powder inside the powder storage. The vent hole is on an upper surface of the powder storage facing the conveyer.
