Abstract

PROBLEM TO BE SOLVED: To positively remove dust of the surface of a recording medium by providing a mechanism for cleaning the recording medium comprising a negative pressure means for creating a negative pressure in a suction aperture part to suck an air, between a first and a second friction members which come into contact with the recording medium, in the upstream of a recording medium transport passage to a recording part where a recording head is pressed against a platen roller. SOLUTION: During a recording operation, a cleaning mechanism 1 sucks an air from a suction aperture 10 by driving a fan 14. A foreign matter such as dust sticking to the surface of a recording sheet 4 is scraped off the surface by a rubbing action by a felt 11 on the stock side while the recording sheet 4 is transported, and is sucked into the suction aperture 10 set to a negative pressure. Further, the foreign matter is removed to the outside of a recording device main body through a duct 13 and the fan 14. In the cleaning mechanism 1, the suction aperture 10 is formed by the felt 11 on the stock side and a felt 12 on the head side which come into contact with the recording sheet 4 respectively, so that the negative pressure of the suction aperture 10 can be increased and even a foreign matter pressed strongly to the recording sheet 4 by a guide roller 5 can be scraped off.

In the cleaning mechanism 1 of the present invention,
Since the suction port 10 is formed by the stock side felt 11 and the head side felt 12 which are in contact with the surface of the recording paper 4, the negative pressure of the suction port 10 can be increased and the guide roller 5 presses the recording paper 5 strongly. Even foreign matter is scraped off by the felt 11 on the stock side,
It can be reliably removed with a strong suction force. Further, since the stock-side felt 11 and the head-side felt 12 are engaged with each other by the adjusting screw 16, the mutual distance can be adjusted appropriately by rotating the adjusting screw 16, and the suction force of the negative pressure means 14 can be adjusted.

Further, the cleaning mechanism 1 of the present invention can remove not only fine dust and paper powder but also relatively large foreign matters such as sand particles by a strong negative pressure. That is, the first
Also, since the suction port 10 formed between the second friction members 11 and 12 has a small cross-sectional area and a large negative pressure, foreign matter such as sand particles is also sucked up, and the duct 13 has a large cross-sectional area and a negative pressure. The pressure drops. Therefore, the suction port 10
The sand particles and the like that have been sucked up are sequentially accumulated in the duct 13. Further, the protrusion 15 provided between the suction port 10 and the fan 14 allows the suction port to be operated even when the fan 14 is not operating, such as when the recording apparatus is in a non-passage state due to accumulated sand particles and the like. There is no backflow to 10.
