Claims

[Scope of claim for utility model registration] Tape 2 led out to the front of main case 1
A front cover 10 that covers the outside of the tape 2 is pivotally connected to the front cover 10 so that it can be opened and closed, and a back cover 21 that covers the back side of the tape 2 is pivotally connected to the inside of the front plate 11 of the front cover 10 so as to be able to swing freely. Sliding shafts 24, 24 provided at the left and right ends of the back cover 21 are fitted into left and right guide grooves 25, 25 provided on the main body case 1 side, respectively, and the front cover 10
The sliding shafts 24, 24 and the guide groove 2
In a tape cartridge configured such that the back cover 21 is opened and closed in a predetermined manner by the guiding action of the left and right guide grooves 25 and 25, one groove bottom surface near the lower end of the left and right guide grooves 25 and 25, and one of the groove bottoms as it moves toward the lower end. One is an inclined surface 32 that gradually protrudes, and the other is an inclined surface 33 that is gradually recessed toward the lower end, and as the sliding shafts 24, 24 move along the guide grooves 25, the left and right groove bottom inclined surfaces 32, 33 and the sliding shafts 24, 24, the back cover 21 moves in the direction of the sliding shaft axis, and when the back cover 21 is in the closed position, the shaft end of one sliding shaft 24 touches this. Corresponding guide groove 25
A tape cartridge characterized in that it is configured to fit below a recessed inclined surface 33 of the tape cartridge.
