The baffle plates 36 that are projected are brought into contact with each other.

In this state, the shaft pin 60 is rotatably inserted into the shaft hole 56 of each CD sheet plate 50 from above, and the lower end portion of the shaft pin 60 is press-fitted into the tubular body 12 of the bed 10. And the CD sheet plate 50 is easily mounted in a short time. After that, the lower sliding flange portion 43 of the large arc plate 41 of the rotating body plate 40 is slidably fitted into the track groove 13 of the bed 10.

Next, the upper cover 20 is covered on the fixed body plate 30 and the rotating body plate 40, and the upper flange portion 33 of the fixed body plate 30 is fitted into the insertion groove 14 of the upper cover 20 to fix the fixed body plate 30. The engaging pieces 34 on the upper side of the plate 30 are respectively engaged with the engaging holes 16 formed in the projecting pieces 25 of the upper cover 20, and the fixed body plate 30 is fixed to the upper cover 20.

Further, the upper end portion of the shaft pin 60 protruding above the uppermost CD sheet plate 50 is press-fitted into the tubular body 22 of the upper cover 20, and the upper sliding flange portion 43 of the rotating body plate 40 is moved upward. By slidably fitting in the track groove 23 of the cover 20, the CD storage box is assembled as shown in each of FIGS. 2 to 4.

Then, as shown in FIGS. 2 and 4, the assembled CD storage box is placed in an outer casing 80 constituted by a bed 10, an upper cover 20, a fixed body plate 30 and a rotating body plate 40. In the state where the CD sheet plates 50 are housed in upper and lower stages, the fixing groove portion 35 provided at the tip of the small arc plate 32 of the fixed body plate 30 projects from the tip of the small arc plate 42 of the fixed body plate 40. The stop portion 44 is engaged to close the rotating body plate 40.

In addition, the protrusions 51 of the CD sheet plates 50 are rotatably fitted to the shaft pins 60 having upper and lower ends held by the protrusions 11 of the bed 10 and the protrusions 21 of the upper cover 20, respectively. The ends of the contact grooves 58 formed on the outer peripheral portion of each CD sheet plate 50 and having the tips open to one arcuate notch 53 are brought into contact with the baffle plate 36 of the fixed body plate 30, respectively.

In the CD storage box of the first embodiment described above, the outer casing 80 supports the upper cover 20 on the bed 10 with the fixed body plate 30 and the rotating body plate 40, and supports the shaft pins 60. Therefore, the CD 70 can be easily attached to and detached from the external casing 80 without removing the CD sheet plate 50 from the outer casing 80, and a partition plate or the like is not provided between a large number of CD sheet plates 50 stacked downward and upward. As a result, a large number of CD sheet plates 50 can be stacked in the outer casing 80 and the same number of CDs 70 can be stored.

When the number of the CDs 70 becomes large and the CDs cannot be stored in one CD storage box, the CDs are held on the CD sheet plate of the storage box having the same structure as shown in FIG. Stack from bottom to top as shown.

In the stacking of the storage boxes, the upper cover 20 of the lower storage box is formed with an engaging portion 27 having a substantially equilateral triangle shape that protrudes downward and is recessed upward. The engaging portion 17 having a substantially equilateral triangle shape is formed so that the protruding upper portion is recessed, and the engaging portion 27 of the upper cover 20 and the engaging portion 17 of the bed 10 are uneven with a slight downward gap. In addition, the non-slip footrests 19 provided on the tops of the engaging portions 17 of the bed 10 and projecting downward engage with the respective tops of the engaging portions 27 of the upper cover 20.

Therefore, the plurality of storage boxes can be stacked without rotating relative to each other or being displaced in the horizontal direction, and the load of the stacked storage boxes can be covered by the upper cover of the storage boxes. There is no phenomenon that pressure is applied to the CD 70 inside the outer casing 80 by falling to the center of the upper surface of the disk-shaped portion and horizontally dispersing. Therefore, when a plurality of storage boxes are stacked vertically and the CD 70 is taken in and out of the storage box, the space does not become so large and is stable. It should be noted that although the storage boxes are stacked in three levels vertically in FIG. 7, the storage boxes may be stacked in two levels vertically or four to six levels.

Since the center hole 71 of the CD 70 is fitted into the holding shaft 55 that protrudes to the center of the shallow recess 54 on the upper surface of each CD sheet plate 50, the CD 70 does not rattle on the shallow recess 54 and is surely secured. Since a large number of ridges are radially formed on the outer periphery of the holding shaft 55 at predetermined intervals, the central hole 71 of the CD 70 can be held more reliably.

Since a pair of arcuate notches 53 are formed in the disc-shaped portion of each CD sheet plate 50 so as to face each other, the CD 70 is attached to and detached from the shallow recess 54 of the CD sheet plate 50. The baffle plate 36 is provided on the inner peripheral surface of the large arc-shaped portion 41 of the fixed body plate 30 so as to protrude downwardly and in multiple stages, and is provided on the lower surface of the outer peripheral portion of the disk-shaped portion of each CD sheet plate 50. Since the end of the contact groove 58 abuts, the CD sheet plate 50 can be rotated without excess or deficiency and positioned and housed in the outer casing 80.

Further, as illustrated in FIG. 5, when the positions of the push handles 52 are formed so as to be different in the circumferential direction, and the CD sheet plates 50 in which the positions of the push handles 52 are different every other stage are stacked in the downward and upward directions. It is preferable that these turning operations can be easily performed.

In the second embodiment of the present invention, as shown in FIG. 8, the axial dimension, that is, the height dimension of the fixed body plate 30, the rotary body plate 40 and the shaft pin 60 is increased to increase the fixed body plate. The number of baffle plates 36 formed in 30 and the number of CD sheet plates 50 are increased, and a CD storage box constituted by using the same bed 10 and upper cover 20 as in the first embodiment. Is. The configurations of the fixed body plate 30 and the rotary body plate 40 of the second embodiment other than those described above are substantially the same as those of the fixed body plate and the rotary body plate of the first embodiment.

The assembly of each member of the second embodiment and the use of the CD storage box according to the second embodiment are also the same as those of the first embodiment, but the number of stacked storage boxes in the second embodiment is two. It is preferable to reduce the number to about 3 steps.

According to a second aspect of the present invention, in the CD storage box of the first aspect, a large diameter hole is formed in an upper portion of the cylindrical body 12 protruding above the protruding portion 11 of the bed 10, and the lowermost stage is formed. A circular protrusion 57 protruding from the lower surface of the protruding portion 51 of the CD sheet plate 50 is rotatably fitted to the large inner diameter portion of the cylindrical body 12, and a shaft penetrating the center of the circular protrusion 57 from the upper surface of the protruding portion 51. Since the large inner diameter portion is formed in the upper portion of the hole 56, the circular protrusions 57 of the upper CD sheet plate 50 are successively rotatably fitted into the large inner diameter portion of the shaft hole 56 of the lower CD sheet plate 50. This process is repeated up to the uppermost CD sheet plate 50, and the axial hole 56 of each CD sheet plate 50 is aligned with the hole of the tubular body 12.

Therefore, the shaft pin 60 is rotatably inserted into the shaft hole 56 of each CD sheet plate 50 from above, and the lower end portion of the shaft pin 60 is press-fitted into the tubular body 12 of the bed 10. Maintenance work is easy and can be done in a short time. The holding shaft 55 is projected at the center of the shallow recess 54 on the upper surface of each CD sheet plate 50, and the center hole 71 of the CD 70 is fitted into the holding shaft 55 to rattle the CD 70 on the shallow recess 54. It is preferable that a plurality of ridges are radially formed on the outer periphery of the holding shaft 55 at predetermined intervals, so that the center hole 71 of the CD 70 can be fitted and held by the holding shaft 55 with certainty.

Since the pair of arcuate notches 53 are provided in the disc-shaped portions of each CD sheet plate 50 so as to face each other, the operation of attaching / detaching the CD 70 to / from the shallow recess 54 of the CD sheet plate 50 is performed. Easy to peel. In addition, the baffle plates 36 are projected in the upper and lower stages on the inner peripheral surface of the large arc-shaped portion 41 of the fixed body plate 30 to form one arc-shaped notch 53 on the lower surface of the outer peripheral portion of the disk-shaped portion of the CD sheet plate 50. Since a contact groove 58 having an open tip is provided so that the end of the contact groove 58 abuts the corresponding baffle plate 36 when each CD sheet plate 50 is accommodated, the CD sheet plate 50 can be rotated without excess or deficiency. Thus, the CD sheet plate 50 can be positioned and housed in the outer casing 80.
