Title: Multi-ink-jet recording apparatus
Inventor: JINNAI KOUICHIROU
IPC: B41J2/09
Filed: 1978-10-03
Abstract: PURPOSE:To prevent a recording paper from getting stained caused by induction noise, without deteriorating deflection accuracy even at the time when a number of heads are arranged, by making a potential of an ink column jetted out from a head higher than a potential of a noise caused by a charging electrode. CONSTITUTION:A charging voltage is impressed onto a charging electrode 3 in accordance presence or adsence of an image signal, and a head potential Vh is  biased to higher potential by Zenner voltage in comparison with GND. This head  potential Vh is set to a higher potential than noise level's maximum value Vn.  And therefore, an ink drop is downwardly deflected regardless of presence or absence of noise, and all the drops are recovered by a gutter 2. On the other hand, at  the time of printing, a charged ink drop is upwardly deflected and made to adhere  onto a printing region a on a recording paper as a printing drop. Since the then  maximum deflection b is smaller than the maximum deflection at the time of recovery by the gutter 2, deflection accuracy can be easily maintained.

Abstract: PURPOSE:To attain recording with high picture quality even on wide recording paper by using a material with a low friction coefficient for at least the surface of a drive roller end in direct contact with a recording element arranging face of a recording head when narrow recording paper is set. CONSTITUTION:Since the friction coefficient between a rubber face (surface of a part not subjected to coating processing with a low friction coefficient material) of a drive roller 1 and the recording paper 4 is sufficiently larger than the friction coefficient between the recording head 4 and a heat element arranging face of the recording head 2, the recording paper is fed to a discharge roller 16 according to the rotation of the drive roller 1. The heat element of the recording head 2 is driven for recording in synchronization with the feeding of the recording paper 4 and a picture image is recorded on the recording paper 4 with head sensing. When the width of the recording paper 4 is narrow, both ends 1A, 1B of the drive roller 1 subjected to coating processing are in direct contact with the heat element arranging face of the recording head 2, but the load exerted on the drive roller 1 is nearly equal to the case when the width of the recording paper 4 is wide and no transient strain is caused on the drive roller 1.
