书写或类似的办公用机色带盒受到不同的设计要求，是对一切事物容易更换，而不弄脏手指，制造成本低廉，应该抑制的声音中的压力范围。 另外，使用磁带盒的过程中机械零件的污染从Öffnugnen避免在盒掉出带的磨损的底部，和一个平稳运行的墨带驱动将成为可能。 这些通用对象是在基部的内部的盒外壳的罐形基体部分（13）（22）突出的加强肋（44，45，46），其同时用于支撑凸缘向上和供给卷轴的卷绕，取得在 /或掉出在墨带的盒壳体磨损累积出所述开口（25，57，58，59）中的阻止。 所需的用于盒外壳加强肋（44，45，46）的尺寸稳定性同时呈现其它功能，例如指导的向上和供带盘卷绕，防止带的磨损从盒壳体等。由此，色带盒是简单且在结构上便宜。

Ribbon cartridges for typing or similar office machines are subject to different design requirements, while above all without dirtying the fingers easily replaceable, inexpensive to manufacture and to dampen the noise in the pressure range. In addition, contamination of the machine parts during use of the cassette is avoided from the Öffnugnen in the bottom of the cassette falling out abrasion of the ribbons, and a smooth-running ribbon drive will be possible. These versatile objects are achieved in that the pot-shaped base part (13) of the cassette housing on the inside of the bottom (22) projecting stiffening ribs (44, 45, 46) which simultaneously serve to support the winding of the flange-less up and supply reel and / or falling out of the waste in the cartridge case abrasion of the ink ribbon out of the openings (25, 57, 58, 59) prevent. The stiffening ribs required for the dimensional stability of the cartridge casing (44, 45, 46) simultaneously perform other functions; as guiding the winding of the assembly and the supply reel, preventing abrasion ribbon from the cartridge case etc .. This is the ribbon cartridge simple and inexpensive in construction.
