PURPOSE:To use plural tapes with just a single cassette case, by loading and unloading freely a holding base accommodating two tapes to a cassette case which is provided with a plate spring on the bottom surface and two holes drilled to the upper surface and with an open front side respectively. CONSTITUTION:A cassette container A is provided with a rear side plate 3, a bottom plate containing a plate spring 4 and having a reel holder, and a top plate having two holes 5. The front side of the container A is opened. A tape holding stage B consists of a front cover plate 9 and a bottom plate 8 having a window 10 and with an L-shaped section. The stage B is coupled to the container A in a loadable/unloadable model. In addition, the stage B has a tape guide, cuts, etc. (not shown in the figure) as well as a reel frame 12, a tape guide plate 21, an elastic plate 17, etc. In such a way, plural tape holding bases are used in combination to a single unit of the container A. This improves the economical performance. |
