    摘要： The present invention relates to a method for driving an ultrasonic motor of the type which includes a vibrator for causing a flexural vibration wave in response to a pair of AC driving voltage signals, and a rotor in contact with the vibrator and moved by the flexural vibration wave. The rotational speed of the ultrasonic motor is controlled by using a feedback signal and a data table, the feedback signal indicating the current rotational speed of the ultrasonic motor, and the data table storing values of the feedback signal as a standard function of the rotational 21 speed. The method includes the step of sampling the feedback signal and detecting the rotational speed in a plurality of rotation states of the ultrasonic motor. The method obtains an approximate function representing the relationship between the sampled feedback signal and the detected rotational speed of the ultrasonic motor, and calculates correction coefficients for adjusting the approximate function to the standard function. The method then controls the rotational speed of the ultrasonic motor by using the feedback signal. In the controlling step, the method corrects the feedback signal obtained from the ultrasonic motor by using the correction coefficient, whereby a value of the approximate function is transformed into a corresponding value of the standard function.

    摘要： An ultrasonic motor has a vibrating body 3 and a moving body 11 supported by a supporting component 7. A rounded lower end of the supporting component is supported in a tapered dent of a supporting base 10, and therefore when a side pressure is applied, it inclines to the supporting base so as to keep the contact between the vibrating body and moving body stable. As a result, a stable motor rotation is always obtained regardless of side pressure. A lead wire 8 is held between a metal elastic element 1 and supporting component, and is pressed against the elastic element. Hence, the lead wire, through contact with the elastic element, is electrically coupled to the common electrode on the upper surface of a piezoelectric element without soldering and without use of conductive resin.

    摘要： A fail-safe capability is realized that not only forestalls the execution by the user of the head replacement operation in an erroneous sequence while the printing apparatus is in operation but also prevents the splashing of ink even if the user attempts to inadvertently replace the print head. For this purpose, the ink supply and the opening and closing of the print head replacement cover are performed by a predetermined rotation of one drive source.

    摘要： An ink jet recording apparatus includes a carriage for mounting therein a recording head which executes a recording operation by discharging ink onto a recording material, a conveying roller for conveying a recording material, and a cap for covering a discharge port of the recording head. In addition, a pump generates a negative pressure in an interior of the cap, a lock member, adapted to be rotated in synchronism with the rotation of the conveying roller, locks movement of the carriage, and a drive transmission mechanism transmits a driving power of the conveying roller to the pump. The drive transmitting mechanism is equipped with a delay mechanism for delaying transmission of the driving power to the pump until the conveying roller has been rotated by an amount corresponding to an amount of rotation of the lock member for shifting the carriage from a locked state to an unlocked state.
