ABSTRACT:
An image sensing apparatus comprises: a mirror which reflects light coming from a photographing optical system at a mirror down position; a mirror support member which rotatably supports the mirror; a contacting member against which the mirror support member contacts at the mirror down position; a rotatable first lever member; and a second lever member to which the contacting member is secured, and which is rotatably held by the first lever member, wherein when the mirror moves to the mirror down position, the mirror support member contacts against the contacting member, the second lever member then rotates relative to the first lever member and contacts against the first lever member, and by rotating the first lever member, the first and second lever members rotate without changing a relative positional relationship, so as to adjust a position of the contacting member with respect to the mirror support member.
