An image acquisition unit acquires an image including an object, and a controller starts a visual servo using the acquired image, on the basis of at least one of an error in calibration, an error in installation of a robot, an error resulting from the rigidity of the robot, an error of a position where the robot has gripped the object, an error regarding imaging, and an error regarding a work environment. Additionally, the controller starts the visual servo when the distance between one point of a working unit of the robot and the object is equal to or greater than 2 mm.

The present invention addresses the problem of providing a nursing wheelchair, comprising a seat member which deploys on a frame body to form a seat. The nursing wheelchair readily allows transfer of a person receiving care, and is lightweight and easy to operate. A nursing wheelchair () comprises seat members () which deploy on seat support frames () constituting part of a frame body () in order to form a seat.

Nursing wheelchair

A liquid ejection apparatus includes a liquid ejecting head that ejects a liquid onto a target; a carriage that is moved to scan in a direction perpendicular to a transportation direction of the target with the liquid ejecting head being mounted on the carriage; a fan that blows gas toward a scanning area of the carriage; and a partition member that is positioned so as to separate the scanning area of the carriage from the fan and block the gas blown from the fan toward the scanning area of the carriage.

Liquid ejection apparatus having fan for cooling the liquid ejecting head

A printing apparatus includes a transport unit that transports a printing medium to a downstream side of a transport direction, a printing head that performs printing on the printing medium, a drying unit that performs a drying process on the printing medium in the course of a transport path of the printing medium, a transport roller that is disposed further to the downstream side in the transport direction than the drying unit, a de-curl roller that pinches the printing medium with the transport roller, and a curl correcting unit that corrects the curl of the printing medium, and the de-curl roller is positioned at a de-curl position of pinching the printing medium with the transport roller at the time of increasing the temperature of the drying unit to a predetermined temperature.

Printing apparatus

A liquid ejecting apparatus includes: a support portion including a support surface that supports a target; a liquid ejecting head that ejects a liquid onto the target supported by the support surface, from a position opposed to the support surface; a housing portion that includes the support portion in a wall portion opposed to the liquid ejecting head and that is formed in a location so that an air suction port that takes in air from the exterior is further from the liquid ejecting head than the support surface in a direction that is orthogonal to the support surface; and an air exhaust unit that exhausts air from the interior of the housing portion.

Liquid ejecting apparatus

The invention prevents and suppresses wasteful expenditure of ink which occurs when recovering nozzles. In greater detail, a plurality of head units arranged in a direction which intersects a transportation direction of a printing medium is provided, a plurality of cleaning units is disposed to face the plurality of head units, and at least one of the plurality of cleaning units is selected and moved so as to be in close contact with the corresponding cleaning unit. By such a method, only the cleaning head unit which faces the head unit of which nozzles need to be recovered is selected and is brought into contact with the head unit, and liquid is sucked in from the nozzles of the head unit.

The heater unit includes: a locking device selectable between a locked state in which the heater unit chassis is locked in the printer chassis, and an unlocked state in which the printer chassis and the heater unit chassis are unlocked; and a grip portion. When the grip portion is in a first operating position, the locking device is held in the locked state, and when the grip portion is in a second operating position, the locking device is held in the unlocked state. The operating state of the locking device changes in an interlocked manner with switching of the operating position of the grip portion.

A printing apparatus includes a rotating drum that holds a recording medium on a cylindrical outer peripheral surface thereof and rotates around a rotating shaft, and a printing head that is disposed opposite to the outer peripheral surface of the rotating drum and ejects ink onto the recording medium held on the rotating drum to perform a printing operation. The rotating drum holds a first recording medium and a second recording medium arranged in a rotating direction. A distance between a rotating direction downstream end of the first recording medium and a rotating direction upstream end of the second recording medium is larger than a distance between a rotating direction downstream end of the second recording medium and a rotating direction upstream end of the first recording medium.

Printing apparatus and printing method

A printing apparatus which mounts a printing medium on a conveyor belt, conveys it to a printing area, and carries out printing by ejecting a liquid onto the printing medium from nozzles of a liquid ejection head, includes: a tension imparter which imparts tension to the conveyor belt, a tension remover which removes the tension imparted to the conveyor belt by the tension imparter, a conveyance failure detector which detects a printing medium conveyance failure, and a conveyance failure controller which, when the printing medium conveyance failure is detected by the conveyance failure detector, causes the tension remover to remove the tension imparted to the conveyor belt by the tension imparter.

An imaging apparatus includes an image sensor; a strobe unit; a preliminary. illumination controller which instructs the strobe unit to preliminarily illuminate for a predetermined period before main illumination; a reading controller which divides the image sensor into a plurality of regions, controls an exposure period for each region, corresponding to the preliminary illumination, and reads an image signal from each of the regions; and an imaging exposure setting unit which sets an appropriate amount of strobe light to be fired during imaging according to the image signals read from the regions; wherein the reading controller controls the exposure period for each region so that an overlapping period with the preliminary illumination period of the strobe unit is different from each other.

Imaging apparatus

An image of appropriate exposure is obtained in a short period of time. A controller and timing generator performs photometric measurement by use of an image signal acquired from a CCD, and determines appropriate light exposure. The CCD is divided into a plurality of regions: for example, an odd-number line region and an even-number line region. Timing at which accumulated electric charges are read from the respective regions is changed, thereby changing the light exposure of an image signal read from each of the regions. When the amount of light fired during the main flash is adjusted by means of causing a strobe to fire preliminary light, read timing is changed in such a way that an electric charge accumulation period of the odd-number line regions comes to an arbitrary point in time during the course of firing of preliminary light. The amount of main flash light can be determined by means of acquiring a plurality of image signals having different light exposures or a photometric measurement signal through single firing of preliminary flash light.

An electrostatic latent image is formed on a rotary image carrier. A developer is provided with at least one developing roller which is separatably abutted on the image carrier at a developing position to supply toner onto the image carrier to make the latent image visible as a toner image. An intermediate transfer member is adapted to temporarily hold the toner image. A transferer applies a transfer bias to primarily transfer the toner image on the image carrier to the intermediate transfer member. A first cleaner is always abutted on the image carrier to remove toner remaining thereon. A second cleaner is separatably abutted on the intermediate transfer member to remove toner remaining thereon. The toner image includes a first toner image which is not to be transferred onto the recording medium and a second toner image which is to be secondarily transferred onto a recording medium. The second cleaner is separated from the intermediate transfer member so as to avoid the first toner image.
