Title: Printer
Inventor: NISHIWAKI MANABU
IPC: B41J2/325
Filed: 1986-09-02
Abstract: PURPOSE:To form pixels in a density of two times the arranging pitch of recording electrodes and alleviate loads on a recording head, a driving circuit or the like, by providing a driving means for applying a voltage between a central recording electrode and both end recording electrodes in an arbitrary group of three adjacent recording electrodes, and a driving means for applying a voltage between an arbitrary pair of recording electrodes. CONSTITUTION:The centers of printing pixels pn-1-pn+8 coincide with the tips of recording electrodes en-1-en+8 while the centers of printing pixels qn-1-qn+8 coincide with midpoints between respective adjacent ones of the recording electrodes. Printing in the printing pixel region pn+4 is carried out by closing switches sn+3, sn+4, sn+5 to apply a voltage between the recording electrodes en+3, en+4, en+5. Printing in the pixel region qn is carried out by closing switches sn, sn+1 to apply a voltage E between the electrodes en, en+1. Thus, a printer can be realized with a recording head having recording electrodes in a density equal to one half of the desired density of pixels, and the numbers of driving circuits and associated controlling circuits can also be reduced by one half.
