摘要： An electric motor has a rotor having an end portion and a recessed portion formed at the end portion. A rotational shaft is mounted to the rotor. A stator covers an outer peripheral portion of the rotor and forms a magnetic field that generates a torque around the rotational shaft to thereby rotate the rotational shaft and the rotor. A bearing rotatably supports the rotational shaft and is entirely spaced-apart from the end portion of the rotor in an axial direction of the rotational shaft. A slider is slidably mounted around the rotational shaft and supports rotation of the rotational shaft about a rotational axis thereof. The slider is interposed between the bearing and the rotor so that a portion of the slider is entirely contained in the recessed portion of the rotor and the remaining portion of the slider is disposed in the space between the bearing and the rotor and in contact with the bearing.

摘要： Disclosed is an ultrasonic motor whose output is improved by enhancing the exciting force of a vibration caused on a vibrating body having a rectangular portion. The ultrasonic motor includes the vibrating body having a piezoelectric element, and a moving body which contacts the vibrating body. The phases of two difference vibrations caused on the vibrating body are changed to make the moving direction of the moving body or the vibrating body itself variable by selecting whether to apply a drive signal to first electrodes provided at one side of the piezoelectric element or to apply a drive signal to second electrodes provided at a portion whose polarization direction differs from that of the first electrodes.

摘要： A control portion always monitors a present-position signal from a position sensor and monitors whether the present position of a moving body is a desired position, or not (Step 101). In the case where the control portion detects that the present position of the moving body reaches the desired position, the control portion generates a stop command signal and gives the stop command signal to an oscillation drive circuit (S102). Then, the control portion checks whether overshooting occurs, or not (S103), and in the case where the control portion judges that overshooting occurs, the control portion retains a stop command signal as it is for a stop command retaining time t (S104). After the stop command retaining time t elapses, the control portion gives a reverse command signal to the oscillation drive circuit to conduct reverse operation (S105). After Step S105, the control is returned to Step S101 and the above operation is repeated. Then, in the case where the control portion judges that overshooting does not occur in Step S103, position correcting operation is completed.

摘要： In a moving mechanism, a contact is disposed on a moving body, and the contact is in contact with a positioning member so as to move the moving body by 180 degrees. With this structure, the accurate regulation of the position of the moving body can be realized with only a slight improvement in the conventional moving mechanism, and the object can be inexpensively realized. Also, since the position detecting means, the signal processing means, etc., are not required other than the moving mechanism, necessary and sufficient functions can be realized with the minimum structure without requiring excessive energy and space.

摘要： The present invention is directed to realize a portable, compact, light, thin, inexpensive and fast printer apparatus. A motor is provided between a printing head unit and a stationary frame member to drive the printing head unit relative to the stationary frame member in leftward and rightward directions, thereby eliminating conventional indirect driving components such as a stepping motor and a lead screw. Further, a sensor is provided in the printing head unit to detect a moving velocity and a position of the printing head unit to thereby construct the printer apparatus having reduced number of components to ensure stable driving and high accuracy. According to such a construction, the motor is integrated into the printing head unit, which self-moves in the printer apparatus to eliminate a mechanism converting a rotational movement into a linear movement, thereby achieving cost down of the printing apparatus.
