Abstract

PURPOSE:To obtain a cassette cap closing mechanism at a low cost by providing a bending working part which is almost vertical to a cassette in a cassette inserting condition to the edge part of a cassette pressing tool. CONSTITUTION:To the edge part of a cassette pressing tool 4, a bending working part A which is almost vertical to a cassette 2 in a condition that the cassette 2 is inserted to a cassette holder 1 is provided. By the removing operation of the cassette 2 from the cassette holder 1, the edge part of a cassette cap 3 is abutted to the bending working part A of the cassette pressing tool 4 as being shown in a figure (b). Further, when the removing operation of the cassette 2 is continued, the cassette cap 3 is revolution-displaced in an arrow direction against the bending working part A of the cassette pressing tool 4 and achieves a closing condition. Thus, by utilizing the member cassette pressing tool 4 to be necessary for the basic constitution of the title device, the increasing of the parts number is suppressed at minimum and the cassette cap closing mechanism of the low cost can be obtained.

The above purpose is to hold the end of the cassette holder supported by the cassette holder while the cassette is inserted into the cassette holder.
It is approximately perpendicular to the cassette, and the bending height is smaller than the height of the cassette positioning protrusion on the cassette holder, with the gap between the tip of the bent part and the lower surface of the lid, which is a decorative member attached to the top of the cassette loading device, when the cassette is inserted. [Operation] This is achieved by providing a bent part with dimensions such that when the cassette is inserted, the cassette holder is supported at the end of the cassette holder so as to be movable in the vertical direction from the cassette holder. A vertical bending section is provided. This results in
When the cassette is drawn out, this bent portion comes into contact with the edge of the cassette lid in an open state, and the cassette 7 is rotated against the bent portion, thereby realizing a closing operation of the cassette 7.
