摘要： An optical scanner which can realize target trajectory tracking machining at a high speed and with a high accuracy. In a servo control circuit controlling the operation of an X-axis scanner for positioning a mirror and the operation of a Y-axis scanner for positioning another mirror, sine wave response is performed at a specific frequency on feedback control for each axis so that the gain characteristic and the phase characteristic of the feedback control are estimated. This arithmetic operation processing is performed by a microprocessor prior to machining, and the results of estimation of the two axes are stored as data for each frequency. In the stage of machining, the results of estimation in terms of the gain characteristic and the phase characteristic are used for correcting the amplitude and phase of a sine wave of a target trajectory in order to cancel each characteristic.

摘要： A scanner system includes a servo control unit. A rotation angle of a rotating shaft supporting a mirror is detected, and an error of the detected value with respect to a commanded value is integrated by an integral compensator so that the detected value is able to track the commanded value. A tracking error proportional compensator is disposed in parallel with the integral compensator so as to add a correction value proportional to the error to the integrated value of the error. A plurality of gains are prepared for each of the integral compensator, the tracking error proportional compensator, a detected value proportional compensator and a detected value differential compensator of the servo control unit. Each gain is changed in accordance with a travel angle of the commanded value. Thus, the mirror can be positioned quickly so that the machining speed can be improved.

摘要： A printing apparatus that includes printing element substrates which are provided with printing elements that discharge ink. A plurality of temperature sensors, each of which is provided with one of the printing element substrates, measures a temperature of a corresponding printing element substrate. A selection unit selects any one of the temperature sensors, and a determination unit performs a determination operation to determine a state of the printing element substrate based on the temperature measured by the selected temperature sensor in a case when only the printing elements of a substrate that corresponds to the selected temperature sensor are driven.

摘要： An ink-jet recording device is capable of correcting a recording position due to a leaning of a printing head and correcting of driving timing between multiple printing heads. Each nozzle row of a printing head is classified into multiple nozzle groups, and the driving timing of the nozzle groups other than the nozzle group serving as a reference of correction of the multiple nozzle groups is adjustable to correct for any leaning of the printing head. Moreover, in the event of performing the driving timing between printing heads, the driving timing of a non-reference printing head is adjustable relative to a reference printing head employed for leaning correction of multiple printing heads.
