Abstract: PURPOSE: To use this device in various modes such as hand holding and arm holding by constituting a scanning module by fixing constituting members except a mirror to a common assembly, and fixing it to each kind of housing so as to be converted. CONSTITUTION: A scanner 10 is provided with a hand type housing 12 whose inside part is divided into an upper half 16 and a lower half 18 by a base 14. A high speed scanning motor 20 is set on the base 14, an U-shaped supporting body 26 is fixed to an output axial part 22 instead of a plane mirror, a laser 1 optical part assembly 28 is fixed to the supporting body 26, and the assembly 28 and the supporting body 26 are shaken and rotated altogether by the axial part 22. The assembly 28 is provided with a hollow slender tube 30, laser diode 32 fixed to one end, lens barrel 34 fixed to the other end, and focusing lens held in the lens barrel 34. An opening through-diaphragm is provided at the end wall of the lens barrel 34, and the lens barrel 34 is fixed in nest type so as to be moved in a vertical direction in the tube 30.
