Claims
- 1. A disk driving apparatus which is arranged to record or reproduce information on or from a recording medium of disk-like shape accommodated in a cassette, by causing a head to move in a predetermined direction while causing the recording medium to rotate, comprising:
- (a) a cassette guide for receiving the cassette, said cassette guide having, on opposite sides thereof, first and second inserting guides for guiding insertion of the cassette, a portion corresponding to a movement path portion for the head being eliminated from said cassette guide to form a space which serves as a movement path space for the head, the first inserting guide of said cassette guide, which is positioned on a side on which the movement path space for the head is formed and which, based upon the movement path space, is made shorter than and is positioned below the second inserting guide, having a projection on a rearmost end portion of the first inserting guide so that the cassette can be supported on the projection;
- (b) a base for holding said cassette guide movably in an inserting direction of the cassette and in a direction perpendicular to the inserting direction so as to cause the cassette to move between a load position and a standby position;
- (c) a head carriage which holds a first head and a second head and which is movable in a radial direction of the recording medium, said head carriage having a head arm for holding the second head in opposition to the first head, said head carriage being disposed in such a manner that a longitudinal direction of said head carriage is approximately perpendicular to a moving direction of said head carriage;
- (d) moving means for causing the second head to move between a first position where recording or reproduction of information on or from the recording medium is possible and a second position wherein recording or reproduction of information on or from the recording medium is impossible, said moving means having a supporting portion for supporting the head arm transversely to the moving direction of said head carriage when the second head is positioned in the second position, a part of the supporting portion being provided with a supporting-portion holding member having an elastic part, the supporting portion having a plurality of shafts of different diameters which are eccentrically and axially connected to each other;
- (e) a panel attached to said base and having an opening for insertion of the cassette and a push button which operably projects from said pane, the push button having a variable amount of projection which varies between the standby position and the load position of the cassette;
- (f) transportation means for executing, when said push button is pressed, a transporting operation for transporting said cassette guide to cause the cassette to move from the load position to the standby position;
- (g) ejecting means for ejecting the cassette in interlocked relation to the transporting operation;
- (h) a stopper provided on said base;
- (i) a latch lever located on and turnably supported on said cassette guide;
- (j) a pin provided on said latch lever, said pin having a movement restricting part on a top of the pin to prevent said pin and said stopper from disengaging from each other in the direction perpendicular to the inserting direction, said pin and said stopper being engaged with each other when the cassette is in an ejected state wherein the amount of projection of the cassette from said panel is approximately the same as the amount of projection of said push button from said panel; and
- (k) urging means for urging said latch lever in a direction in which said pin is brought into abutment with said stopper at all times.
- 2. A disk driving apparatus according to claim 1, wherein said pin has an engagement recess engageable with said stopper.
- 3. A disk driving apparatus according to claim 1, wherein said movement restricting part has a disk-like shape.
