Abstract: A bobbin for electrically insulating the stator core from a coil wire to be wound around the bobbin includes: a coil winding portion around which the coil wire is to be wound; and a terminal fixing portion to which a winding starting end portion and a winding finishing end portion of the coil wire are to be fixed. The terminal fixing portion includes a first groove configured to guide a winding starting section extending from the winding starting end portion of the coil wire to a winding starting position of the coil winding portion and a second groove configured to guide a winding finishing section extending from a winding finishing position of the coil winding portion to the winding finishing end portion of the coil wire to intersect the winding starting section when seen in an axial direction.

Abstract: 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.
