Claim:
1. A printer comprising: a paper path that guides paper used as a recording object through a predetermined path; a conveyance mechanism that in a predetermined direction, conveys the paper guided through the paper path; a sensor that includes a pair of sensor elements arranged to oppose each other across the paper path and to be movable along a direction orthogonal to a direction of conveyance of the paper by the conveyance mechanism; and a recording unit disposed on the paper path to perform a recording operation with respect the paper conveyed through the paper path by the conveyance mechanism, based on a result of detection by the sensor, wherein the sensor elements in the sensor are respectively interlinked with a guide unit via an elastic member biased in a direction of coming into contact with the guide unit that forms a wave shape along the orthogonal direction and is formed on a frame supporting the conveyance mechanism and the recording unit, the elastic member elastically deforming according to the wave shape of the guide unit, the sensor elements are disposed to be moveable along the guide unit by elastic deformation of the elastic member according to position along the orthogonal direction, the guide unit corresponding to one sensor element of the sensor and the guide unit corresponding to another sensor element of the sensor respectively form the wave shape protruding and receding at same positions along the orthogonal direction.
