发明名称 IMAGE FORMATION DEVICE
摘要 PURPOSE:To discharge fine ink mists produced from ink droplets together with a recording medium out of a device by controlling in such a manner that the capacity of a fan is increased as the number of image formation data increases and shielding a recording surface formation part by means of an air curtain blown off from the fan. CONSTITUTION:When a signal, RFH reporting that, for example, 50% or more of nozzles have delivered, is sent from a recording head unit 110 to a control unit CTL, the CTL sends a signal DFH to a DC fan motor M4 for sucking recording paper P to increase the capacity of a fan, whereupon an air flow from a fan 390F for sucking paper is deflected by a duct member 390D so as to be blown off from a gap between a platen 392 and a mount base 302, so that the air flow runs against a printing surface (direction of arrow A) of printing paper P to form an air curtain. As a result, fine ink mists produced by projection of ink of a head 110 are uniformly attached to the paper P, while the mists are discharged out of a device, preventing the device from being contaminated.
