Claims (1)

[Claims for Utility Model Registration] A magnetic tape 9, a pair of hubs 10 and 11 around which the tape 9 is wound, and a case 8 that accommodates the tape 9 and the pair of hubs 10 and 11; is an opening 1 for exposing the front surface 2 and the back surface 3 facing each other and the magnetic tape 9;
7 and a rear surface 5 opposite said front surface 4.
A magnetic tape cassette 1 is provided with a pair of side surfaces 6 and 7, and a recess 18 is provided at a position offset from the center of the back surface 5 to distinguish between the front surface 2 and the back surface 3. It is a device that performs conversion, and converts the tape cassette 1 into the pair of hubs 10,
A container 19 formed to be inserted in a direction that corresponds to the direction in which a straight line connecting the containers 11 to each other extends.
and when the tape cassette 1 is inserted into the container 19 with the directionality, the tape cassette 1
a movable plate 48 provided so as to be pressed by one of the pair of side surfaces 6 and 7 of the tape cassette 1 so as to move in a direction coincident with the direction of the straight line; a base portion 61 extending in the insertion direction of the tape cassette 1 and a tip portion 62 selectively inserted into the recess 18, the base portion 61 being connected to the movable plate 48;
The distal end portion 62 is rotatably supported by the tape cassette 1, and is configured such that when the tape cassette 1 is taken out of the container 19, the distal end portion 62 receives a force from the edge of the concave portion 18 in the direction of pulling the distal end portion 62 out of the concave portion 18. a rotating body 60 for distinguishing the front and back sides of the cassette, which is provided with an inclined surface 73; and a spring that applies a biasing force to the rotating body 60 in a direction in which the tip end 62 of the rotating body 60 approaches the back surface 5 of the tape cassette 1. 69, when the tape cassette 1 is normally inserted into the container 19 so that the back surface 3 of the tape cassette 1 faces the movable plate 48, the tip end 62 is inserted into the recess 18. The rotating body 60 is allowed to move in the insertion direction of the tape cassette 1 together with the movable plate 48 while the tape cassette 1 is held so that the surface 2 of the tape cassette 1 faces the movable plate 48. When the tape cassette 19 is inserted into the container 19 by mistake, the distal end portion 62 remains inserted into the recess 18 to prevent the rotating body 60 from moving in the insertion direction of the tape cassette 1 together with the movable plate 48. 1. A cassette-type magnetic tape device comprising a blocking portion 65, characterized in that the tip portion 62 is attached to the base portion 61 so as to rotate within a predetermined angular range.
