Cassette storage case

Abstract

A slide type cassette storage case in which a tape cassette is inserted laterally through an insertion port provided on a side surface thereof so as to eliminate a generation of warp or surface sink after molding because of a difference of thickness between concave grooves 35, 36 which retreats from an expanded portion of the tape cassette and thick portions 32 e , 33 e along the concave grooves 35, 36. Providing thickness missing portions 48, 45 substantially in the center of the thick portion 32 e , 33 e along the concave grooves 35, 36.

What is claimed is:  
     
         1 . A cassette storage case comprised of a upper half and a lower half and in which a tape cassette is inserted laterally through an insertion port provided on a side surface thereof and stored, wherein 
 the cassette storage case is molded integrally such that the upper half and the lower half are linked to each other in a developed state thereof and by bending a link portion between the the upper half and the lower half are joined to each other and    reel stopper pieces elastically deformable so as to engage with tape reels in the tape cassette to block a rotation thereof are formed integrally with an inner surface of the lower half.    
     
     
         2 . The cassette storage case according to  claim 1 , wherein the upper half and the lower half are fixed to each other by engagement.  
     
     
         3 . A cassette storage case according to  claim 1 , wherein polypropylene resin is used as molding material thereof.  
     
     
         4 . The cassette storage case comprised of a upper half and a lower half and in which a tape cassette is inserted laterally through an insertion port provided on a side surface thereof and stored, wherein 
 a deep wall portion opposing said inserting port is formed such that a deep wall of the upper half is superposed on a deep wall of the lower half and a notch which retreats from a protrusion provided on a side surface portion is formed on the inner surface side of the deep wall portion.    
     
     
         5 . The cassette storage case according to  claim 4 , wherein a thickness of the deep wall portion in which the notch is formed is larger than a protruding length of the protrusion of the tape cassette.  
     
     
         6 . The cassette storage case according to  claim 4 , wherein the cassette storage case is constituted such that the upper half and the lower half are integrally molded so as to be linked to each other in a developed state thereof and by bending a link portion between the upper half and the lower half as a hinge at the time of assembly, the upper half and the lower half are joined.  
     
     
         7 . The cassette storage case according to  claim 6 , wherein the cassette storage case is constituted such that the upper half and the lower half are fixed by engagement.  
     
     
         8 . A cassette storage case having a structure in which a tape cassette is inserted laterally through an insertion port provided on a side surface thereof and stored and having concave grooves which retreat from an expanded portion of the tape cassette formed in a cassette insertion direction of an inner surface of the case, wherein 
 thickness missing portions are provided substantially in the center of the thickness missing portion along the concave groove.    
     
     
         9 . The cassette storage case according to  claim 8 , wherein front and rear portions in the cassette insertion direction along the concave grooves are formed thick while the other portions thereof are formed as thickness missing portions.  
     
     
         10 . The cassette storage case according to  claim 9 , wherein the front and rear end portions in the cassette insertion direction along the concave grooves are formed as cassette holding portions for holding the tape cassette substantially without any gap in the case.  
     
     
         11 . The cassette storage case according to  claim 8 , wherein the thickness of the thickness missing portion is substantially the same as the thickness of thin portion adjacent to the thick portion.  
     
     
         12 . The cassette storage case according to  claim 8 , wherein the cassette storage case is constituted such that the upper half and the lower half are integrally molded so as to be linked to each other in a developed state thereof and by bending a link portion between the upper half and the lower half as a hinge at the time of assembly, the upper half and the lower half are joined to each other and the upper half and the lower half are fixed by engagement.  
     
     
         13 . The cassette storage case according to  claim 12 , wherein 
 the upper half and the lower half are fixed by engagement.
