A robot controller that controls a robot by automatically obtaining a controller capable of suitably controlling a wide range of robots. An image is acquired from an image capturing apparatus that photographs an environment including the robot. The robot is driven based on an output result obtained by inputting the image to a neural network. The neural network is updated according to a reward generated in a case where a plurality of virtual images photographed while changing an environmental condition of a virtual environment generated by virtualizing the environment and a state of a virtual robot are input to the neural network, and a policy of the virtual robot, which is output from the neural network, satisfies a predetermined condition.

Robot controller that controls robot, learned model, method of controlling robot, and storage medium

An apparatus captures an image of an ID tag displaying printed ID information specific to a patient to acquire an ID-tag image, and acquires a color correction value from the ID-tag image. The color correction value is used to correct an image to be captured. The apparatus corrects a captured image of an affected area by using the color correction value.

Information processing apparatus, image capturing apparatus, and information processing method

A handheld display apparatus including a display unit that displays an image includes a handheld grip portion including a plurality of bar members to be gripped by a user, and an operation unit that receives a manual operation and generates a control signal for the handheld display apparatus, the operation unit arranged on either at least one of the plurality of bar members or in proximity to at least one of the plurality of bar members.

Handheld display apparatus having contact portion proximate to display and grip portion manually attachable to and detachable from display

Handheld display apparatus having head contact portion, handheld grip portion and manual operation unit that causes generation of control signal for handheld display apparatus

A head mounted device mounted on a user's head includes a display unit that displays an image to the user, a holding member that holds the display unit to the user's head, and an auxiliary member, including a rotation unit, that assists the holding member by rotating about the rotation unit to contact a front of the user's head. The rotation unit includes a biasing member that biases the auxiliary member in a direction of pressing the front region of the user's head and a restricting member that restricts the rotation at the rotation unit.

Head mounted device

In the case of performing duplex printing on a continuous sheet, by setting a length of a non-image area to an optimum length, both of mark detection having high reliability and the suppression of a sheet consumption amount are achieved. For this purpose, when duplex printing of a plurality of images on front and back surfaces of the continuous sheet is performed, on the basis of a length of the image to be printed precedently to a non-image area Won the second surface, the length of the non-image area common to the front and back surface is set.

Printing apparatus and printing method

A sheet conveyance apparatus including a conveyance unit configured to convey a sheet, wherein the conveyance unit includes a slanting surface having an inclination with respect to a horizontal surface and a conveyance surface that forms, together with the slanting surface, a space that becomes narrower downward in the vertical direction and which moves in a predetermined direction, and conveys the sheet in a predetermined direction by the movement of the conveyance surface.

Sheet conveyance apparatus, sheet cutting apparatus, and image forming apparatus

A sheet conveying apparatus coveys a sheet while nipping the sheet between a conveyance roller and a pinch roller. The pinch roller includes a first roller portion and a second roller portion adjacent to each other in a rotational axial direction thereof. The pinch roller further includes a mechanism configured to change a difference between a pressing force that the first roller portion applies to the conveyance roller and a pressing force that the second roller portion applies to the conveyance roller.

Sheet conveying apparatus and printing apparatus

A printing apparatus includes a print head for inkjet printing, and a guide disposed opposing the print head and configured to guide a back surface of a sheet being conveyed in a first direction. The back surface is a reverse surface of a surface being printed. The printing apparatus further includes a receiving unit disposed opposing the print head and configured to receive ink outside the sheet being conveyed, and a mechanism configured to change a position of the guide in a second direction relative to the receiving unit being fixed, according to a size of the sheet to be used. The second direction crosses the first direction.

Printing apparatus

A recording apparatus includes a recording head, a roller configured to convey a recording medium, an acquisition unit configured to acquire information about a conveyance amount for conveying the recording medium per a predetermined rotation amount of the roller, a recording timing generation unit configured to generate a plurality of timing signals for performing recording for one raster line according to a rotation of the roller during one rotation thereof, and a drive signal generation unit configured to generate a drive reference signal for performing the recording for the one raster line on the recording medium at a predetermined interval based on the conveyance amount information and the timing signal.

Recording apparatus

A printing apparatus includes: a upstream roller pair arranged on the upstream side of a printing head with respect to a direction in which a sheet is conveyed; and a downstream roller pair arranged on the downstream side of the printing head with respect to the direction, wherein each of the upstream roller pair and the downstream roller pair includes a first roller and a second roller configured to hold the sheet therebetween. In both of the upstream roller pair and the downstream roller pair, a rotation shaft of the second roller is provided to be situated on the downstream side of a rotation shaft of the first roller with respect to the direction.

A sheet conveyance apparatus includes: a guide unit for guiding the side end of the sheet; a first roller pair arranged on the downstream side of the guide unit for conveying the sheet, including a driven roller held in contact with a whole sheet in a sheet width direction; and a second roller pair having a conveyance roller arranged on the downstream side of the roller and adapted to convey the sheet, and a plurality of pinch rollers pinching the sheet in cooperation with the conveyance roller, wherein each of the plurality of pinch rollers applies to the sheet a conveyance force inclined toward a conveyance path side end, which is nearer to the pinch roller, and wherein the smaller the distance between the pinch roller and the conveyance path side end, the greater the inclination of the conveyance force thereof.
