摘要： A tape cartridge according to an embodiment of the present technology includes: a reel; a cartridge case; a reel lock member; and a reel lock release member. The reel includes a reel hub including a cylindrical bottom portion. The reel lock member includes a projecting portion projecting toward the cylindrical bottom portion in a uniaxial direction and is urged in the uniaxial direction to engage with the reel hub. The reel lock release member includes a main body and a plurality of leg portions, the main body being disposed between the reel lock member and the cylindrical bottom portion, the plurality of leg portions extending from the main body in the uniaxial direction and being inserted into a plurality of through holes, the reel lock release member releasing engagement of the reel lock member and the reel hub. The main body includes a central portion and a plurality of extension portions, the central portion being in contact with the projecting portion, the plurality of extension portions extending radially along a direction perpendicular to the uniaxial direction from the central portion to end portions connected to the plurality of leg portions, thicknesses of the plurality of extension portions along the uniaxial direction gradually decreasing from the central portion toward the end portions.

摘要： [Solving Means] A tape cartridge according to an embodiment of the present technology includes: a tape reel; a cartridge case; and a reel lock member. The tape reel includes a reel hub having a bottomed cylindrical shape, a tape having been wound on the reel hub. The cartridge case includes a first protruding portion and a plurality of second protruding portions, the first protruding portion protruding toward a center of a bottom portion of the reel hub, the plurality of second protruding portions being arranged around the first protruding portion. The reel lock member is disposed inside the reel hub. The reel lock member includes a first tubular portion and a plurality of second tubular portions, the first tubular portion fitting with the first protruding portion, the plurality of second tubular portions fitting with the plurality of second protruding portions. The reel lock member is movable in a direction of the one axis between a lock position and a lock release position, the reel lock member engaging with the bottom portion of the reel hub at the lock position, engagement between the reel lock member and the bottom portion of the reel hub being released at the lock release position.
