The present invention suggests a device for reproducing a cylindrical hologram. The device for reproducing a cylindrical hologram comprises a main body which has an open upper part and includes an accommodating space therein; an operation button arranged on an outer side of the main body; a driving device which includes a driving motor installed on one inner side of the main body, and a driving wheel that is joined with the driving motor by a shaft to rotate; a driving plate which includes a guide hole in the center thereof and an area around the guide hole formed with a disk contacting with the driving wheel to receive rotational force from the driving motor, and is mounted on the top of the driving device; a transparent cylinder which is mounted on the driving plate to rotate with the driving plate and has an inner surface to which the cylindrical hologram is tightly attached; and a light source which is arranged on the center of the inside of the main body to project a reference light to the cylindrical hologram tightly attached to the transparent cylinder. |
