- the inner rotor 4 When the gear portion 43 engages with the gear portion 70a of the rack bar 70, the inner rotor 4 is rotated according to the amount of movement of the rack bar 70.
- the coil panel 7 is stretched by the rotation of the inner rotor 4, and the panel power is accumulated.
- FIG. 21 shows a state before the gear portion 70 a of the rack bar 70 engages with the gear portion 43 of the inner rotor 4.
- the convex-side joint 50a and the concave-side joint 50b of the pair of shirt members 5a, 5b are abutted against each other and are in close contact with each other.
- the opening 42 of the inner rotor 4 is located at a position inclined with respect to the opening 6 of the lower shell 22, only the overlapping central portion of the two openings 6, 42 is opened. Force The opening is closed by a pair of shirt members 5a and 5b. Therefore, there is no danger that dust may enter the disc housing from the overlapping portion of the openings 6 and 42.
- a shaft mounting portion 50c of a pair of shirt members 5a, 5b is interposed at a portion where the opening 6 and the opening 42 are close to each other at an acute angle. c is located inside the second and fourth tall portions 12 e and 12 g of the rib-shaped convex portion 12 a to eliminate the gap. Further, a closing projection 55 is interposed between the first and third tall portions 12 d and 12 f to eliminate the gap. Further, the elongated hole 53 formed in the pair of shirt members 5a and 5b is closed by the lower shell 22 on which the shirt members 5a and 5b overlap. Furthermore, as shown in FIG.
- a substantially H-shaped rib-shaped convex portion 12 a provided on the lower shell 22 so as to surround the opening 6 has a groove provided on the shutter members 5 a and 5 b.
- a crank-shaped dustproof portion is formed by fitting into the concave portion 12b to prevent dust from entering the disk storage portion through the openings 6, 42.
- the rack rod 70 enters the guide groove 31 in response to the insertion operation of the recording medium cartridge 1, and the gap between the gear portion 70a and the gear portion 43 of the inner rotor 4 is formed.
- the inner rotor 4 is rotated clockwise.
- the convex portion 46 for lifting up the inner rotor 4 is formed on the upper shell 21. Since the pair of shirt members 5a and 5b are sandwiched between the lifter projection 18 and the inner rotor 4 with the pair of shirt members 5, a relatively large force is exerted on the rotation of the inner rotor 4. Needed. As shown in Fig.
- the protrusions for lift-up are formed by rotating the inner rotor 4 by piles with a large frictional force caused by mutual climbing. 8,4 6 Disengagement from each other and the frictional force disappears. Therefore, the rotation operation of the inner rotor 4 thereafter can be performed extremely lightly and smoothly.
- the trapezoidal projections 48, 48 for releasing the fitting provided on the bottom surface of the inner rotor 4 become the first and third backs of the rib-shaped projections 12 a of the lower shell 22.
- the inner rotor 4 is lifted up from the lower shell 22 by riding on the upper sections 12d and 12f, and the shirt members 5a and 5b are also raised to form a rib-shaped convex. Part 1
- the groove-like recesses 1 2b come off from 2a.
- the bearing holes 52 of the shirt members 5a and 5b are similarly rotated by the rotation of the inner rotor 4, while the elongated holes 53 provided on the other end side have the boss shape of the lower sur 22. Are slidably engaged with each other.
- the pair of boss-shaped projections 20 are provided on the lower shell 22 and do not move.
- the long hole 53 is formed with the bearing hole 52 so that the slot 53 can move relative to the bosses 20 and 20 following the rotation of the shirt members 5a and 5b. Since the boss-shaped protrusion 20 extends in the direction S connecting the boss-shaped protrusions 20, the boss-shaped protrusion 20 extends in the elongated hole 53 according to the amount of rotation of the shirt members 5 a and 5 b. Relative to the side. As a result, in each of the shirt members 5a and 5b, the bearing hole 52 moves to the corresponding boss-shaped convex portion 20 side. As a result, from the state of FIG. 23, through the states of FIGS.
- the shutter members 5a and 5b are connected to the opening 4 of the inner rotor 4. Move to both sides of 2. Thus, the upper and lower openings 6, 42 are completely opened. Therefore, a part of the optical disk 3 stored in the disk storage part is exposed by the openings 6 and 42. Then, reproduction or recording of the information signal by the recording / reproducing apparatus main body 62 is executed.
- the recording medium cartridge 1 After reproducing or recording the information signal, by operating a cartridge ejection button (not shown) provided on the disk recording / reproducing apparatus 60, the recording medium cartridge 1 is driven by the loading mechanism so that the disk recording / reproducing is performed. Discharged from device 60.
- the inner rotor 4 When the recording medium cartridge 1 is ejected, the inner rotor 4 is rotated in the opposite direction to that when the recording medium cartridge 1 is inserted into the disk recording / reproducing device 60 by the squeezing of the coil panel 7 which has been stored, and the shutter 5 is automatically turned off. Close. Therefore, when ejecting the recording medium cartridge 1, the gear portion 70a of the rack bar 70 of the shutter release mechanism of the disk recording / reproducing device 60 is engaged with the gear portion 43 of the inner rotor 4, so that the inner rotor 4 is This eliminates the need for rotation, and makes it possible to discharge the recording medium cartridge 1 easily and quickly, and to prevent wear of the gear portion 43 of the inner rotor 4. Because
- the coil spring 7 may be a straight line.
- the coil spring 7 may be a compression coil spring instead of a tension coil panel.
- the coil spring assembling portion 4 a is formed by recessing the end of the outer peripheral surface 4 b of the rib portion 41 of the inner rotor 4 on the plane portion 40 side into an annular shape.
- the outer peripheral portion 7 a of the coil spring 7 projects from the outer peripheral surface 4 b of the rib portion 41 of the inner rotor 4 so as not to interfere with the cartridge housing 2.
- a sufficient gap G is provided between the inner rotor 4 and the cartridge housing 2 so that the outer peripheral portion 7 a of the coil spring 7 does not contact the inner surface of the cartridge housing 2. Still good. Industrial applicability
- the present invention can be widely applied to not only optical disk cartridges but also magnetic disk cartridges such as CDs, magneto-optical disk cartridges, and the like.
