Figure (a) shows an embodiment of the present invention. Reference numeral 21 denotes an outer casing of a video disc player which has a box-like appearance, and on the front side there is a casing for playing a disc. An insertion opening 22 is formed.Furthermore, a plurality of operation switches 23 are provided on the front operation wheel. 23

6 is attached, the transparent plate 25 is removed from the front 8, and interference fringes are detected from the outside, that is, from the front, from the top.
Using '6A as a medium, the presence of the disc can be easily confirmed from a wide angle.
