PROBLEM TO BE SOLVED: To provide a video distortion correction mechanism having a function for removing video distortion caused by a reflection mirror including an unequal-side trapezoid occurring when the reflection mirror is out of the same plane by inexpensive and easy operation. SOLUTION: Both sides of the reflection mirror 4 are held and fixed between mirror holding members 15a and 15b and a Z-shaped fixing metallic fitting 6, and further coupling members 7a and 7b fixed at the lower ends of the respective members 15a and 15b and mirror supporting members 9a and 9b are joined, so that the mirror 4 is fixed in a frame 12. Wherein, the members 15a and 15b are constituted to be positionally adjusted vertically with respect to the members 9a and 9b, and adjusted so as to keep the flatness of the reflection surface of the mirror 4.
