とするホログラムスキャナ。(1) A plurality of hologram lenses that focus laser light and deflect it in a predetermined direction to scan the scanning surface rotate a hologram disk formed along its periphery at high speed, and are supported coaxially with the hologram disk. A rotating mirror is fixed coaxially and obliquely to a rotating disk that rotates at a low speed, and a laser beam incident on the rotating mirror from the axial direction via a mirror fixed to the periphery is transmitted to the periphery of the hologram disk. The scanning surface is scanned with a laser beam, and the scattered light reflected from the object surface placed on the scanning surface is transmitted through the hologram lens, mirror, and rotating mirror to a condensing lens onto a photodetector. A hologram scanner is configured to read a bar code written on the object plane by concentrating light on the object surface. A hologram scanner characterized in that a laser beam is made to enter the rotating mine from an axial direction through a mirror.
