Reference numeral 17 is a lid for opening and closing the disk access 5, and is rotatably supported with a pivot 17a inserted in a rotary concave part 18 provided in the corner of the case main body 2. The lid 17 is a resin formed piece of polyacetal, and is composed by integrally forming functional parts mentioned below, and differs in color from the case main body 2. Reference numeral 19 is an elastic deforming pawl (clasp) provided at the end portion on the lid 17 at the nearly opposite side to the position of the pivot 17a. As shown in FIG. 2, this pawl 19 is intended to fit and fix the lid 17 to the case main body 2 by fitting into a pawl hole (clasp hole) 20 provided in the side wall 6b when the disk access 5 is closed by the lid 17. In this state, the arc portion 21 of the lid 17 composes the accommodating wall of the disk accommodating part 8 together with the arc portion 7a of the inner wall 7 mentioned above. Reference numeral 22 is a resin spring provided near the pivot 17a of the lid 17. This resin spring 22 abuts against the straight portion 7b of the inner wall 7 and is deformed when the lid 17 is fixed in the case main body 2, and acts as thrusting means for generating a thrusting force in a direction for opening the lid 17. This resin spring 22 can abut against the outer circumferential end portion of the disk 1 when the lid 17 is opened, and acts also as an elastic deforming abutting member (or abutting portion). Reference numeral 23 is a stopping bar disposed at a position symmetrical to central axis A--A (see FIG. 5) passing through the opening 9, and in the assembled state of the cartridge, it is means for fixing the lid 17 to the case main body 2, by engagement with a stopping hole 24 provided individually in the upper half 3 and lower half 4. As shown in FIG. 4, meanwhile, the stopping bar 23 is formed of resin integrally with the lid 17, and is coupled with the lid 17 through a thin wall portion, and the side to be engaged with the stopping hole 24 has a groove to be engaged with the leading end of the screw driver, while the other side is inserted into a discharge hole 25 provided individually in the upper half 3 and lower half 4, and the discharge hole is clogged while fitting with the discharge hole. By inserting the leading end of a screwdriver into the groove of the stopping bar 23 and rotating, the thin wall portion is divided, and the stopping bar 23 can be detached from the discharge hole 25. As shown in FIG. 3, reference numeral 26 is a semicircular handle provided in the middle of the lid 17, and is engaged with the notch 12 of the upper half 3 and lower half 4. Reference numeral 27 is a movable piece formed integrally with the lid 17, having write-inhibit holes 11a, 11b, and is coupled with the lid 17 movable through an elastic linkage branch 28. The movable piece 27 comprises a cylindrical detection protrusion (or detecting lid) 29 positioned at a predetermined position showing record disable or record enable by the convex and concave portions provided in the inner side of the write-inhibit hole 11a by fitting into the write-inhibit hole 11a, and a moving hole 30 for allowing to move the detection protrusion 29 from the write-inhibit hole 11b (see FIGS. 6 to 10). The protrusion of the invention corresponds to the detection protrusion 29. Reference numeral 31 is a protrusion to be engaged with the releasing portion of the write-inhibit hole 11a (see FIG. 5), and 32 is a stopping pawl (or stopping clasp) to be engaged with a concave part 33 provided in the side wall 5a of the upper half 3 and lower half 4 (see FIGS. 1 and 3), and is deformed elastically for preventing the upper half 3 and lower half 4 from loosening. Reference numeral 34 is a penetration hole opened in the lid 17. This penetration hole 34 is provided at a position corresponding to positioning holes 10a, 10b provided in the upper half 3 and lower half 4, respectively.
As shown in FIG. 9, as the side portion of the detection protrusion 29 is engaged with a concave part 11u provided at the inner side of the write-inhibit hole 11a, the detection protrusion 29 is held at the shown position as far as external force is not applied.
FIG. 10 is a sectional view of B--B line in FIG. 7, explaining the structure of the moving hole 30. As shown in the drawing, a piece like a pin having a thin end is inserted from the write-inhibit hole 11b into the moving hole 30, and the detection protrusion 29 is moved to record enable position or record disable position.
As shown in FIG. 12 and FIG. 13, reference numeral 35 is a defining unit formed in the lid 17. This defining unit 35 is for defining the rotation of the lid 17 by abutting against one end of the side wall 6c of the case main body 2. As shown in the drawings, moreover, reference numeral 36 is a disk guide groove for holding and guiding the disk 1 discharged from the disk access 5. As shown in FIG. 11, with the lid 17 opened to the maximum extent, distance K (see FIG. 13) from an inner circumferential end 51b of the opening 5b of the disk access 5 to the bottom of the disk guide groove 36 is set slightly larger than the diameter of the disk 1. The place set in this distance K is the narrowest position, except for the position of distance L mentioned later, in the route of passing of the disk 1, when the disk 1 is discharged. The distance L from the inner circumferential end 51b of the opening 5b of the disk access 5 to the leading end of the resin spring 22 of the lid 17 is set slightly smaller than the diameter of the disk 1 in the state of the resin spring 22 not deformed elastically. The resin spring 22 has a function of an elastic deforming abutting member. When the disk 1 discharged from the case main body 2 from the disk access 5 abuts simultaneously against the inner circumferential end 51b of the opening 5 and the leading end of the resin spring 22, only the resin spring 22 is deformed elastically, and by its restoring force, accordingly, the disk 1 is temporarily held between the inner circumferential end 51b and the leading end of the resin spring 22. The move suppressing/stopping means of the invention is the means comprising the inner circumferential end 51b and the leading end of the resin spring 22. The abutting portion provided at a specific position of the lid of the invention corresponds to the resin spring 22, and the abutting portion provided near the disk access of the invention corresponds to the inner circumferential end 51b. As shown in FIG. 13 and others, when the disk 1 is held by the inner circumferential end 51b and resin spring 22, it is composed so that the central hole 1a of the disk 1 may be opposite to the notch 12.
When the cartridge of the embodiment is loaded into the cartridge holder (not shown) and inserted in the direction of arrow B (see FIG. 14), the shutter opener 41 is engaged with the opener concave part 13a of the slider 13 (see FIG. 5 and the slider 13 is moved by resisting the thrusting force of the torsion spring 16 (see FIG. 1), so that the shutter 14 moves in a direction of exposing the opening 9. When the opening 9 is completely exposed, the cartridge descends to the base stand 37 side by loading mechanism not shown, and two positioning pins 40a (see FIG. 14) provided on the base stand 37 are fitted into positioning holes 10a, 10b (see FIG. 5) at the case main body 2 side, and two positioning pins 40b provided in the base stand 37 abut against the top of the case main body 2, thereby completing loading of the cartridge. At this time, the disk motor 38 and pickup 39 are inserted into the opening 9, and the disk 1 is mounted on the turntable 38a. The cartridge detection switch 43 abuts against the stopping bar 23, and the write-inhibit switch 42 abuts against the detection protrusion 29.
By holding the handle 26 of the lid 17 by hand, when turned in the direction of opening the lid 17, the detection protrusion 29 of the moving piece 27 slides in the write-inhibit hole 11a, and moves from the releasing position to the outside of the case main body 2. By further rotating, the lid 17 is opened to the maximum rotation position as shown in FIG. 13. In this state, when the case main body 2 is inclined, the disk 1 contained in the disk accommodating part 8 is guided along the straight lines 7b, 7c of the inner wall 7 by the action of gravity, and begins to move straightly toward the disk access 5 as indicated by arrow P in FIG. 13, and is discharged outside of the case main body 2 through the disk access 5. At this time of discharge operation, one side of the outer circumferential end of the disk 1 abuts against the bottom of the disk guide groove 36 of the lid 17 (or the inner circumferential end 51b of the opening 5b), and the moving speed is lowered. Consequently, one side of the outer circumferential end of the disk 1 moves along the disk guide groove 36 of the lid 17. That is, as shown by arrow Q in FIG. 13, the disk 1 moves while changing the moving direction from direction P to direction Q. Shortly after, the inner circumferential end 51b of the opening 5 and the leading end of the resin spring 22 abut against the disk 1 simultaneously from both sides of the outer circumferential end of the disk 1. As a result, the resin spring 22 is deformed elastically, and the disk 1 is temporarily pinched and held between the inner circumferential end 51b and the leading end of the resin spring 22 by the restoring force of elastic deformation. FIG. 13 shows the temporarily held state of the disk by the restoring force. At this time, sine the central hole 1a of the disk 1 is exposed from the notch 12 of the case main body 2, it can be easily taken out of the cartridge by pinching the central hole 1a and outer circumference of the disk 1 by fingers.
To put the disk 1 into the case main body 2, the operation is reverse to the procedure of taking out. Holding the central hole 1a and outer circumference of the disk 1 by finger, it is inserted into the disk access, and is held by the resin spring 22. Then, pushing the outer circumference of the disk 1 by finger, engagement with the resin spring is cleared, and the disk 1 is slipped into the disk accommodating part 8. By turning and closing the lid 17, the clasp 19 of the lid is fitted into the clasp hole 20 of the case main body 2, and is fixed in the case main body 2. At this time, the stopping clasp 32 of the lid 17 is fitted into the concave part 33 of the upper case 3 and lower case 4 to hold the upper case 3 and lower case 5, so that lifting of the case main body 2 near the disk access 5 is prevented.
