Claims

[Scope of utility model registration request]

A cassette in which an outer circumferential rib is formed on the head corresponding part of the upper case to partition a part of the bottom plate into the inside and outside, and the outer part of the bottom plate divided by the outer circumferential rib is formed to be thinner than the inner part of the bottom plate. In the case, a thin portion adjacent to the outer circumferential rib and having the same thickness as the outer portion of the bottom plate is provided in a portion of the inner portion of the bottom plate along the outer circumferential rib, and a thin portion opposite to the outer circumferential rib of the thin portion. a wall thickness changing portion adjacent to the side and having a wall thickness that gradually increases from the thickness of the thin wall portion to the wall thickness of the inner portion of the bottom plate as it goes in a direction away from the outer circumferential rib; Characteristic cassette case.
