Title: Image recorder
Inventor: ODAI YOSHIAKI
IPC: B41J2/215
Filed: 1997-12-02
Abstract: PROBLEM TO BE SOLVED: To form a high quality image at uniform density by arranging a plurality of ink mist generating means but not more than one half of the number (n) of aperture electrodes in an image recorder, thereby making uniform the density of ink mist in the breadthwise direction of a print head. SOLUTION: An image recorder comprises a plurality (n) of aperture electrodes for jetting charged ink mist from a chamber selectively through an opening onto a recording medium by varying the voltage polarity depending on a print data, and mist generating means of number not more than n/2. When a microcomputer 6 delivers an aperture electrode drive signal based on the print data at the time of image recording, the signal is received at each aperture electrode drive section 5. The aperture electrode drive section 5 switches the voltage polarity of an aperture electrode 3 based on the received electrode drive signal and jets ink mist selectively from the aperture electrode 3 to record a character or an image.

Filed: 1988-12-28
Abstract: PURPOSE:To suppress the resonance of a head caused by the high recording density and to prevent the occurrence of read/write errors by sticking both vibration damping members which are effective to the high and low frequency bands to a gimbal. CONSTITUTION:The resonance of a head occurs at high frequencies 2 - 6kHz and low frequencies 200 - 400Hz respectively owing to the increase of the recording density. Thus the vibration damping members 12 and 13 which are effective to the high and low frequency bands respectively are directly adhered to a gimbal part 5 to absorb the head resonance. In this case, the member 12 uses sorbofiber and gel, etc., and the member 13 uses polyester film and a thin copper plate (phosphor bronze) respectively. Thus it is possible to prevent the resonance of the head caused by the high recording density and to avoid the occurrence of the read/write errors.
