A box for reserving cassette or cartridge comprises a shield having flanges and channels on its outer surface for engaging with other shields, and a drawer assembled in the said shield for accepting cassette or cartridge, which having accessories of a spring and a steel ball etc. and may be opened from said shield to present the reserved cassette or cartridge by slightly pressing the front wall of the drawer. Therefore, the present invention is convenient for taking out or putting in a cassette or cartridge. Due to the fact that a plurality of boxes can be engaged together, the boxes may be easily classified and managed according to the tapes contained therein. Furthermore, the boxes occupy a smaller space than conventional boxes. |

DETAILED DESCRIPTION OF THE INVENTION As shown in FIG.
1, the box of the present invention comprises a shield and a drawer.
The top wall 1 of the shield has two parallel rails 11, 11', each having a vertical outer side and an inward sloping side.
Between the two parallel rails, there is a flange 12 having two sections of grooves 13, 13'.
The drawer may be inserted into the shield, which comprises a bed 3 for a cassette or cartridge, a front wall 31 and a rear wall 35.
A label having description regarding the reserved tape may be adhesived on the front wall 31.
The two lobes 32,32' insert into the holes of the two hubs of the cassette placed therein.
33, 33' represent two channels.
34, 34' represent two slots.
The bottom wall 2 as shown in FIG.
2 comprises two channels 21, 21' and a concavity 22 corresponding to the rails 11, 11' and the flange 13 on top wall 1 of the shield respectively.
23 represents a sloping block.
The bottom side of the cassette bed 3 contains a groove 36 where a steel ball 28 may rotate freely therein.
The front end 37 of the groove 36 is a loop having a shape shown in the figure.
The area toward the rear end of the groove 36 has a gradually decreased depth.
As shown in FIG.
3, the inner structure of the shield comprises two channel 21, 21', a rounded protuberance 25 is connected with a spring 26, a stripe 29 is connected to the bottom wall 2, which has two upwardly bent edges 291, 291' for engagement with the two corresponding channels 33, 33' on the cassette bed 3 of the drawer.
Near the front end of the stripe 29 is a hole 27 having a steel ball 28 therein.
The relation of steel ball 28 and the groove 36, when open and close the drawer, is disclosed in FIG.
4.
As the two edges 291, 291' of the stripe 29 on the bottom wall 2 of the shield are engaged with the two channels 33, 33' on cassette bed 3 of the drawer.
The steel ball 28 is clamped between the hole 27 on the stripe 29 and the groove 36 on bottom side of the drawer.
When the drawer is closed, the steel ball 28 is at the position A in the front end 27 of the groove 36 as shown in FIG
