Patent ID: 7775158

Claim:
An electrostatic printing apparatus for rubbing powdery ink into a screen having a predetermined printed pattern formed therein, and applying a voltage between the screen and an object so as to attach the powdery ink to the object, said electrostatic printing apparatus comprising: a carrier conveyer for transferring the object; a screen moving mechanism for moving a plurality of screens along a circulatory orbit to a position located above the object moved by said carrier conveyer; and a synchronizing mechanism for synchronizing a moving speed of the object by said carrier conveyer and a moving speed of the screens by said screen moving mechanism; a screen brush for rubbing powdery ink into one of the screens; an object detecting sensor for detecting whether or not an object is placed on said carrier conveyer at an upstream side of a printing position; and a brush separation mechanism for separating said screen brush from the one of the screens when said carrier conveyer is moved to the printing position in a case where said object detecting sensor detects that an object is not placed on said carrier conveyer.
