Claims

[Scope of Claim for Utility Model Registration] (1) A lock plate 8 made of plastic that locks the front cover 4, which is pivotally attached to the front side of the main body case 1 so as to be able to open and close freely in the closed position, is attached to the main body case 1. A spring piece 27 is attached to the lock plate 8 so as to be able to swing freely between a lock position and an unlock position in the direction of the lock plate 8, and elastically deforms in the thickness direction of the plate 8. In the tape cartridge integrally formed, the lock plate 8 has a spring piece 27 extending from the plate main body 8a in a cantilevered manner and having a detour section in the middle, and the extending end 32 of the spring piece 27 extends from the plate body 8a in a cantilevered manner. A tape cartridge characterized in that it is received by a spring receiving part 35 on the main body case 1 side. (2) The tape cartridge according to claim 1, in which the entire spring piece 27 is almost completely contained within the thickness t of the plate body 8a. (3) The intermediate detour portion of the spring piece 27 has two or more thin-walled flexible arms 29 and a thick-walled torsion arm 30 that connects these flexible arms 29. Claim 1 or The tape cartridge according to item 2.
