Disc apparatus having improved construction for guiding movement of operating member for disc rotation

A disc apparatus comprising:

• a holder for inserting therein a cartridge containing a disc having a planar disc surface;
• a sliding member having an operating member under the control of a user with the operating member extending outwardly from the sliding member along a direction substantially parallel to the planar disc surface, wherein said sliding member slides along a direction in response to insertion of the cartridge into said holder so as to move said holder into a loading position, wherein said sliding member slides along another direction in response to operation of said operating member by the user so as to move said holder into an insertion/ejection position, and wherein said disc apparatus accesses the disc in a condition in which said holder is in said loading position and the user either takes out the cartridge from said disc apparatus or inserts the cartridge containing the disc into said disc apparatus in a condition in which said holder is in said insertion/ejection position;
• a guiding portion for guiding the movement of said operating member along a side of said operating member, with said operating member having a groove extending along said side for receiving said guiding portion to form a tongue and groove coupling, wherein said side of said operating member lies in a direction extending substantially parallel to the disc surface and said guiding portion restricts a movement of said operating member along a direction perpendicular to the planar disc surface;
• and
• a front member fixed substantially on said disc apparatus, wherein said front member has a insertion hole through which either the cartridge is ejected from said disc apparatus or the cartridge containing the disc is inserted into said disc apparatus, wherein said guiding portion comprises a part of said front member.
