FLENS FIXING UNIT AND LASER SCANNING UNIT HAVING THE SAME

摘要

An ftheta lens fixing unit and a laser scanning unit having the same are provided to attach and detach an adhesion unit in re-adjusting a position of an ftheta lens by including a plurality of adhesive receiving holes. An ftheta lens fixing unit(140) is inserted between the ftheta lens and the mount and fixes an ftheta lens to a mount(131). The ftheta lens fixing unit has an area wider than an actual contact area of the ftheta lens and the mount and includes an adhesion unit(141). The adhesion unit includes a plurality of adhesive receiving holes(142) which are penetrated to be filled with an adhesive(150). The ftheta lens fixing unit further includes knob units(143) which are formed at both facing sides of the adhesion unit and caught by a user to transfer the ftheta lens or adjust a position of the ftheta lens.
