Recording reproducing apparatus

A recording-reproducing apparatus, comprising:

• recording-reproducing means for recording and for reproducing of information on a recording medium;
• a container member for containing the recording medium therein, and being provided with an opening through which said recording-reproducing means bears against the recording medium, said container member having a substantially quadrilateral shape and having protrusions of different shapes formed on a pair of opposed sides of the quadrilateral shape, said protrusions providing an indication of the proper mounted position of said container member;
• first holding means for holding said container member in proper position as indicated by said protrusions;
• second holding means;
• a driving member held by said second holding means for driving the recording medium;
• and
• restraining means provided on said first holding means, and for restraining said first holding means at a position adjacent said second holding means when said container is held in a proper position in said first holding means as indicated by said protrusions.

A recording-reproducing apparatus, comprising:

• driving means for rotatably driving a recording medium contained in a container member;
• first holding means having one side and an opposite side, for holding on said one side the container member for containing a recording medium therein, and on said opposite side thereof provided with a rotatable member for pressing the recording medium against said driving means;
• second holding means for holding said driving means;
• link means for linking said first and said second holding means to enable said first holding means to move toward and away from said second holding means;
• recording-reproducing means for recording and for reproducing of information on the recording medium;
• and
• resilient means having a first pressing portion and a second pressing portion, for pressing said container member against one side of said first holding means with said first pressing portion when said first holding means is spaced apart from said second holding means, and for pressing said container member with said first pressing portion and said second pressing portion when said container member is moved toward said opposite side of said first holding means when said first holding means is moved adjacent said second holding means.

A recording-reproducing apparatus, comprising:

• a container body having a pair of container halves for containing a recording medium therein;
• a pair of liner members each of which is held between a separate one of said container halves of said container body and the recording medium, and each of which forms waves in the circumferential direction with respect to the center of the recording medium, each of said pair of liner members being fixed to one of said pair of container halves at radially formed portions which are in contact with said one of said pair of container halves;
• means for rotatively driving the recording medium;
• and
• recording-reproducing means for recording and for reproducing of information on the recording medium contained in said container member and held between said liner members.

A recording-reproducing apparatus for recording information thereon and provided with a plurality of light-transmitting portions for transmitting light rays therethrough, said apparatus comprising;

• a container body for containing the recording medium therein and provided with a plurality of openings each corresponding to one of said plurality of light-transmitting portions;
• recording-reproducing means for recording and for reproducing of information on the recording medium;
• photoelectric conversion means disposed to face one side of said container body, said photoelectric conversion means including a light-emitting element and a light-receiving element each facing a separate one of said light-transmitting portions;
• and
• light path change means, having an optical member facing each of said light transmitting portions, disposed to face the other side of said container body, said optical member changing the direction of travel of light rays from one of said light-transmitting portions and causing said light rays to travel to the remainder of said light-transmitting portions.

A recording-reproducing apparatus operable with a container member containing a recording medium therein, comprising:

• first holding means having an upper surface for holding the container member, said first holding means defining an opening into which said container member is received in an insertion direction, said opening having a height greater than the thickness of said container member so that said container member can move in a predetermined direction substantially perpendicular to the insertion direction when received in said opening;
• resilient means, provided in said first holding means, for pressing said container member in the predetermined direction away from said upper surface;
• means for rotatively driving the recording medium contained in said container member;
• second holding means for holding said driving means;
• link means for linking said first and said second holding means for relative movement toward and away from each other, said container member being held away from said upper surface of said first holding means by said resilient means when said first holding means is moved away said second holding means in a first position, said second holding means acting against the pressing force of said resilient means to force said container member to move toward said upper surface of said first holding means when said first holding means is moved toward said second holding means in a second position;
• adjusting means, provided in the region of said upper surface of said first holding means, for adjusting the position of the recording medium in said container member when said first holding means is moved toward said second holding means to the second position;
• and
• recording-reproducing means for recording information on the recording medium and for reproducing information from the recording medium.
