Zusammenfassung:A linear head module includes linear motors each of which includes a movable element and a stator. The movable element includes a shaft having a shaft axis, and magnets fixed to the shaft. The stator includes a coil and a back yoke having a back yoke axis. The movable element is inserted into the back yoke movably along the shaft axis such that the shaft axis substantially coincides with the back yoke axis. The back yoke includes a protruding portion protruding outwardly. The coil is fixed to the back yoke to face the magnets. The linear motors are arranged such that the protruding portion of a first linear motor among the linear motors protrudes along a first protruding direction different from a second protruding direction along which the protruding portion of a second linear motor among the linear motors protrudes.
