<p>PROBLEM TO BE SOLVED: To insert a cassette smoothly at a time without confirmation of the direction, by forming symmetrically recessed grooves containing the swelled parts of the cassette at both right and left inside faces in the insertion direction of the cassette. SOLUTION: This cassette case 1 is constituted of the upper half 1A and the lower half 1B which are unified with ultrasonic welding or the like. One side face thereof fully opened forms an insertion opening 2 through which a cassette 10 is contained by sliding it sideways. And hence, recessed grooves 3a, 3b containing swelled parts 16a, 16b of the cassette are formed in the lateral directions, or the inserting direction of the cassette 10, at respective inside faces of the upper and lower halves 1A, 1B, in the inside of the cassette container case 1. Since the recessed grooves 3a, 3b are symmetrically formed at both right and left sides of the insertion direction of the cassette, the cassette can be inserted therein even from any directions.</p> |
