It is necessary to slidably provide the recording medium with the position of the erroneous erasure prevention member that can be seen through the erroneous erasure prevention window portion so that whether the recording is permitted or not can be visually confirmed.

[0004]

By the way, the position where the above-mentioned plurality of terminals and the erroneous erasure prevention member are exposed is generally on the back surface of the cassette case, and it is optimal for various reasons. The back of the case is also the labeling area.

Therefore, even if the position where the terminals and the erroneous erasure prevention member are exposed is brought closer to one end of the rear surface of the cassette case, the position where the terminals are exposed and the position where the erroneous erasure prevention member is exposed are arranged side by side. However, there is a problem in that the label sticking area becomes smaller accordingly.

Further, in a recording / reproducing apparatus using a recording medium cassette in which a plurality of terminals as described above are exposed on the outer surface of the cassette case, a plurality of terminals are used to read the information displayed by the terminals. It is necessary to provide a connector that comes into contact with the terminals, and if the connector is at a high position, the position through which the recording medium cassette passes when the recording medium cassette is mounted becomes high, and the height of the entire apparatus increases accordingly. There's a problem.

[0007]

And an erroneous erasure prevention member slidably attached to the cassette case is exposed from the erroneous erasure prevention window.

[0008]

[0009]

Therefore, in the recording medium cassette of the present invention,
Since the part that exposes multiple terminals and the part that exposes the erroneous erasure prevention member are arranged vertically, one exposed part will fit within the width of the other exposed part, and the label sticking area will be narrowed. Therefore, the label sticking area can be widened accordingly. Further, an arc-shaped partition wall and an intermediate wall formed so as to extend from a position substantially in the middle thereof toward the rear wall of the cassette case are provided, and the rear end edge of the intermediate wall is provided.
By disposing the substrate between the rear wall and the rear wall, the positioning of the substrate having the erroneous erasure prevention member and the plurality of terminals and the like becomes easy. Furthermore, on one substrate, multiple terminals
IC is mounted with the terminal arrangement part where
Since the IC mount part that is
When the contact piece contacts the terminal with a predetermined elastic force, the board
Mounted at a position where stress applied to the terminal avoids the terminal placement part
It does not extend to the existing IC. And big
It is also possible to use a Kina IC.

Further, such a recording medium cassette is used
In the recording / reproducing apparatus, the provision of the connector that contacts the plurality of terminals can prevent the height of the entire apparatus from being increased as compared with the related art.
