Abstract: An inkjet recording apparatus includes a plurality of nozzles, a pressurizing element, a driver, a controller and a control circuit. The pressurizing element is provided for each of the nozzles. The driver drives the pressurizing elements. The controller generates image data indicating whether ink is ejected for each of the nozzles. The control circuit transmits ejection waveform data indicating a signal transmitted to the pressurizing element and the image data. After printing according to the image data transmitted to the driver is completed, in a non-printing state in which there is no image data to be subsequently printed, the control circuit transmits at least one of the image data indicating a blank sheet and the ejection waveform data in which the ink is not ejected, to the driver.

Abstract: An inkjet recording apparatus includes a feeding-side motor, an inkjet recording unit, a winding-side motor, a feeding-side roll-diameter measuring unit, a winding-side roll-diameter measuring unit, and a motor drive controller. Based on a relationship between motor rotating speeds and roll diameters under conveyance of the recording medium at a specified conveyance speed, the motor drive controller determines a first rotating speed corresponding to a feeding-side roll diameter measured by the feeding-side roll-diameter measuring unit and moreover determines a second rotating speed corresponding to a winding-side roll diameter measured by the winding-side roll-diameter measuring unit to drive the feeding-side motor at the first rotating speed and moreover drive the winding-side motor at the second rotating speed.

Abstract: An information processing apparatus includes a display section, a touch count determining section, a rotation angle detector, a rotation angle determining section, and an image processing section. The display section displays an object. The touch count determining section determines a touch count on the display section. The touch count is a number of touch points on the display section. The rotation angle detector detects a rotation angle of a touch action including multiple touch points on the display section as a rotation specification angle. The rotation angle determining section determines a rotation performance angle by which the object is rotated based on the rotation specification angle and the touch count. The image processing section rotates the object by the rotation performance angle.

Abstract: Provided is a touch panel apparatus that receives a user operation even when a touch panel cannot accurately detect the touch position. A display unit displays an input screen on which a plurality of operation keys is arranged. A touch sensor detects contact on the input screen and outputs coordinates corresponding to a position where contact is detected. A normal-input-receiving unit receives an operation on the input screen based on a detection result of the touch sensor. A screen-control unit displays a cursor for selecting an operation key in the case where the normal-input-receiving unit cannot detect an operation based on the detection result of the touch sensor. A cursor-operation-receiving unit receives a cursor operation for moving the cursor based on the detection result of the touch sensor while the cursor is being displayed.

Abstract: Image forming apparatus is disclosed. The developing portion is replenished with toner from a toner containing body by operating a toner feeding mechanism. The receiving portion receives a designation of switching to a low speed i.e. switching the rotation speed of the motor from the first speed to the second speed lower than the first speed. The measuring portion measures a value of a counter electromotive voltage generated in the motor by causing the motor to operate the toner feeding mechanism. The motor control portion causes the motor to rotate at the first speed until an absolute value of the value measured by the measuring portion is not larger than a predetermined first value, and causes the motor to rotate at the second speed after an absolute value of the measured value is smaller than the first value, in the case where the switching to a low speed is designated.
