Patent ID: 7959248

Claim:
A recording apparatus comprising: a recording unit configured to record images on a recording medium of a roll-type, the recording unit including at least one recording head of a line-type having a configuration corresponding to a width of the recording medium; a first pair of rollers located at an upstream side of the recording head, configured to nip the recording medium to convey the recording medium along a path; a second pair of rollers, located at a downstream side of the recording head, configured to nip the recording medium to convey the recording medium along the path, wherein a pressure applied to the recording medium by the first pair of rollers is greater than a pressure applied to the recording medium by the second pair of rollers, and the second pair of rollers rotates at a faster peripheral velocity than the first pair of rollers; a first signal generation unit, including a laser doppler speed meter for detecting a surface of the recording medium being conveyed, configured to generate a first signal according to a movement speed of the recording medium, wherein the laser doppler speed meter detects the surface of the recording medium being recorded by the recording head at the upstream side of the recording head; a second signal generation unit including a rotary encoder, configured to generate a second signal according to a rotation of one of the first pair of rollers; and a control unit configured to control recording on the recording medium based on the first signal and the second signal so as to suppress adverse effects caused by the first pair of rollers.
