In a cassette loading device of the invention in which columnar cam followers formed on both the sides of a cassette holder are guided by inclined cam grooves formed in both the sides of a slide member upon reciprocal movement of the slide member so as to reciprocate the cassette holder between a cassette inserting position and a cassette loading position, a D-cut surface is formed on a portion of each cam follower which is located away from the center of the columnar cam follower toward the cassette loading position side with respect to the cassette inserting position, thereby reducing the ejection stroke and ejection operating force of the slide member which are required to eject the cassette holder from the cassette loading position to the cassette inserting position.
