Abstract

An ink jet printer comprising a recording device for jetting ink droplets from a printer head while moving in a direction perpendicular to the direction of conveyance of a recording medium in the form of a sheet, to form a dot image on the recording medium according to an input time, further including a pair of sheet retaining devices respectively arranged before and behind in the direction of travel of the recording device, where one of the pair of sheet retaining devices arranged before in the direction of travel is displaced to push against the recording medium in order to form a predetermined clearance between the printer head and the recording medium, while the other is displaced to leave from the recording medium.

Claims

1. An ink jet printer comprising:

recording means including a printer head for jetting ink droplets while moving in a direction perpendicular to the direction of conveyance of a recording medium in the form of a sheet, to form a dot image on said recording medium according to an input time, further comprising a pair of sheet retaining means respectively arranged before and behind in the direction of travel of said recording means, said pair of sheet retaining means being operated in such a manner that the one of said pair of sheet retaining means arranged before in the direction of travel is displaced to push against said recording medium in order to form a predetermined clearance between said printer head and said recording medium, while the other is displaced to leave from said recording medium.

2. The ink jet printer as claimed in claim 1, wherein each of said sheet retaining means comprises:

a solenoid and a swingable sheet retaining lever for swingably moving said swingable lever.

3. The ink jet printer as claimed in claim 2, wherein said sheet retaining means further comprises a wheel at a free end of said swingable sheet retaining lever.
