摘要:
A sheet material separating apparatus includes a sheet material separating unit. This unit includes a low frictional guide sheet making a surface contact with an upper surface of an uppermost one in stacked sheet materials, and a vibrator contacting a surface of the guide sheet opposite to another surface of the guide sheet contacting the upper surface of the uppermost sheet material. A length from a part of the surface of the guide sheet on which the vibrator contacts to any position on a peripheral edge of the surface is longer than one wavelength of an excited sound wave.

An electrostatic actuator comprises first and second stator sections having a first electrode array arranged in a first direction, and a second electrode array of electrodes extending in the first direction, respectively. A movable section having fifth and sixth electrodes arranged to face the first and second electrode arrays, respectively, is arranged between the first and second stator sections. A driving circuit alternately performs a first driving operation in which a DC voltage is applied between the adjacent electrodes of the first electrode array and a second driving operation in which a DC voltage is applied between the electrodes of the second electrode array. The voltage application is successively performed by deviating the positions of the electrodes to which the voltage is applied so as to move the movable section in the first direction while vibrating the movable section between the first and second stator sections.

An ink-jet recording apparatus records an image onto a recording medium by flying an ink-droplet from an ink surface by a pressure of an ultrasonic beam. The apparatus including an ultrasonic generating element array having a plurality of ultrasonic elements arranged in an array for emitting ultrasonic beams, a driving device for applying a plurality of pulses having different phases from each other, and a converging device for converging the ultrasonic beams by interfering the ultrasonic beams with each other. The generating elements are simultaneously driven and sequentially shifted in an array direction, and the converging device converging the ultrasonic beams in a direction perpendicular to the array direction.

摘要:
An ink-jet recording apparatus which includes a recording medium for carrying an electrostatic image, an ink-ejecting section opposing the recording medium and located in non-contact state with respect to the recording medium medium, and having an ink holding section for holding ink and an opening section for ejecting ink, at least one counter electrode located in the ink-ejecting section to be immersed in ink. The ink is ejected by virtue of an electric field between the electrostatic image formed on the recording medium and the counter electrode.
