Claims

[Scope of Claim for Utility Model Registration] (1) A supply tape reel 2 and a take-up tape reel 3 are rotatably arranged on the left and right sides of the main body case 1, and a reel presser plate spring 6 is installed on the inner surface of the upper wall 5 of the main body case 1. A tape formed by fixing a fixed part 6a at the center in the left and right longitudinal direction of the tape, and pressing the tape reels 2 and 3 with respective free ends 6d and 6e of arm parts 6b and 6c extending from the fixed part 6a in the left and right direction. In the cartridge, the free heights from the inner surface of the upper wall 5 of both free ends 6d and 6e on the supply tape reel side and the take-up tape reel side are set to be equal, and when not in use, the free end portions 6d and 6e on the supply tape reel side are set to the same height. The spring pressure of the arm portion 6b is set higher than the spring pressure of the arm portion 6c on the take-up tape reel side, and the spring pressure of the arm portion 6b on the supply tape reel side and the arm portion 6c on the take-up tape reel side during use. A tape cartridge characterized in that the spring pressure of the tape cartridge is set substantially equal to the spring pressure of the tape cartridge. (2) The tape cartridge according to claim 1, in which the planar shape of the reel presser plate spring 6 is formed asymmetrically.
