| 20150085015 | PRINTING APPARATUS - Air blown out from one blowing-out opening of a pinch roller which is within a predetermined angle range forms an air flow of a flow rate Fc which heads for a region between a suction mechanism and a print medium. This makes it possible to efficiently guide the air blown out from the blowing-out opening into the region, and as a result, ink mist can be collected satisfactorily even in a case where the amount of air blown from the pinch roller is relatively small. Further, in this case, the flow rate Fe of a flow blown from the pinch roller is appropriately determined, whereby the suction mechanism can collect substantially 100% of air and ink mist flowing into the region. | 03-26-2015 |
