Abstract: A conveyance device holds a sheet medium in a roll and includes a drive roller that feeds the sheet medium from the roll to a conveyance path; and a roll rotating unit that rotates the roll forward to convey the sheet medium toward the drive roller and in reverse to rewind the sheet medium and that has multiple drive modes with different speeds of rotation. A control unit controls driving the drive roller and the roll rotating unit, such that, when starting a reverse conveyance operation that rewinds the sheet medium, the control unit selects the drive mode to be used in the reverse conveyance operation based on a first conveyance distance, which is the distance the sheet medium is to be conveyed in the reverse conveyance operation, and the diameter of the roll stored as roll diameter information and as calculated after an immediately previous reverse conveyance operation.

Abstract: A printer with a tractor unit driven by a DC motor and a printing control method that acquires accurate load information when continuous paper is loaded. The printer has a printhead 2 that can move in a primary scanning direction and has discharge nozzles that discharge liquid onto continuous paper, and a tractor unit 4 that is driven by a DC motor Mt and conveys continuous paper toward the printhead 2 in a secondary scanning direction perpendicular to the primary scanning direction. The printer 1 and printing method also have a load information acquisition unit 23 that, when continuous paper is loaded in the tractor unit 4, drives the tractor units 4 at least two different constant conveyance speeds V1, V2, and acquires load information I1, I2 for the DC motor Mt at the at least two different conveyance speeds.

Abstract: According to one embodiment, an electronic device includes an input controller, a detector, a layer controller, and a rendering controller. The input controller is configured to receive data indicative of an object to be rendered on a screen comprising layers. The detector is configured to detect an attribute of the object received by the input controller. The layer controller is configured to assign the object to either an existent layer or a new layer belonging to the layers of the screen, the layers connected with attributes. The rendering controller is configured to render on the screen, objects assigned to the layers.

Abstract: An information processing apparatus includes a transmitter, a receiver, and a key assignment changing module. The transmitter is configured to transmit information relating to a use situation of the information processing apparatus to an external storage device. The receiver is configured to receive, from the external storage device, key assignment information which is based on the information relating to the use situation and transmitted by the transmitter. The key assignment changing module is configured to change a key assignment of a keyboard connected to the information processing apparatus based on the received key assignment information.

Abstract: A conveyance device has a roll rotating unit that rotates a roll of sheet medium forward and in reverse, and a conveyance path along which is an upstream roller and a downstream roller for conveying the medium and cooperate in a reverse and rewind operation. A control unit controls driving of the upstream roller, the downstream roller, and the roll rotating unit, such that, during the reverse and rewind operation, the control unit (i) drives the upstream roller and the roll rotating unit, (ii) stops driving the upstream roller while continuing to drive the roll rotating unit, first slack being created as a result of (i) or (ii), (iii) causes the medium to be nipped at the downstream roller, and (iv) drives the upstream roller while the medium is nipped at the downstream roller to create second slack.

Abstract: According to one embodiment, an electronic apparatus includes a depth estimation module, a parallax calculation module, a video generation module, a sub-image parallax determination module, a sub-image generation module, and a display control module. The depth estimation module estimates depths corresponding to pixels in a frame of video data. The parallax calculation module calculates parallaxes by using the depths. The video generation module generates left-eye and right-eye video data by using the video data and the parallaxes. The sub-image parallax determination module determines (i) a first depth for displaying a sub-image and (ii) a first parallax by using the first depth. The sub-image generation module generates left-eye and right-eye sub-image data by using sub-image data and the first parallax. The display control module displays a left-eye image and a right-eye image by using the generated data.
