摘要： A recording apparatus includes: a recording head that performs recording on a recording target medium; a driving mechanism that is capable of causing the recording head to move closer to the recording target medium or move away from the recording target medium; and a controlling section that determines driving amount for one driving operation that is performed by the driving mechanism on the basis of results of a comparison made between a first recording head movement direction that is taken or to be taken in the one driving operation and a second recording head movement direction that was taken in another driving operation that is immediately before the one driving operation and thus precedes the one driving operation.

摘要： The invention provides, as a first aspect thereof, a gap adjustment apparatus that includes: a recording section; a guide axis that supports the recording section in such a manner that the recording section can move while facing a recording target medium, the guide axis being able to move in such a manner that a gap between the recording section and the recording target medium can be adjusted; a cam section that is either provided directly on the guide axis or provided not directly on the guide axis so as to engage indirectly with the guide axis, the cam section being able to rotate so as to move the guide axis; a rotatable member that rotates together with the cam section; an arm section that is provided either as a part of or on the rotatable member and substantially radiates out from a rotation axis line of the rotatable member; and a rotating section that is brought into engagement with the arm section as the recording section moves in a main scan direction and rotates the rotatable member by transmitting a force to the rotatable member via the arm section.
