BRIEF SUMMARY
TECHNICAL FIELD

The present invention relates to a disc rack for containing disc type record plates or the like, such as audio discs or video discs.


BACKGROUND ART

As shown in Unexamined Japanese Utility Model Publication No. 59-39475, a conventional disc rack from which a desired disc can be easily taken out comprises a plurality of holders having a pair of nippers. The holders are arranged in parallel and placed in a box-type container having an opening at the front part. Rotating the holders about the supporting rod, the holders can be taken out of the container. In the disc container, indication levers have an end swinging when an opposite end is pushed by the circumferential portion of a disc. The levers are used to detect and indicate whether a contained holder holds a disc. In this structure, the levers can not be activated smoothly if indicating levers are not accurately assembled. This is likely to cause malfunction and therefore a problem that levers can not precisely indicate whether a disc is held or not.
The present invention, having overcome the above problem, has an object of providing a disc rack with a simple structure which makes it possible to precisely indicate whether or not a disc is held.


DISCLOSURE OF THE INVENTION

According to the present invention, a disc rack comprising a plurality of holder members for holding a disc in a vertical direction, a supporting frame for supporting the holder member in such a way that the holder member is turnable about a supporting rod from a drawn-out position to a retracted position and vice versa, a positioning member able to come into contact with a circumferential portion of a disc loaded in a holder member when the holder member is put in the retracted position for positioning the holder member being loaded with the disc at an angle different from that of a holder member not being with a disc.
According to the present invention, also, the positioning member able to come into contact with a circumferential portion of a disc loaded in a holder member being attached to an attachment portion provided on a back plate of the supporting frame.
According to the present invention, further, a top plate of the supporting frame is provided with a guide member having a guide portion for guiding the holder member when the holder member is turned, the positioning member able to come into contact with a circumferential portion of a disc loaded in a holder member being provided at aback end of the guide member.
According to the present invention, further more, the positioning member is able to come into contact with a disc loaded in a holder member so that a front surface of the holder member comes in agreement with a front surface of the supporting frame when the holder member is put in retracted position, and a slide portion is provided on the holder member, the slide portion being able to come into contact with the positioning member so that an upper portion of the holder member is positioned inside of the supporting frame with the holder member being inclined when the holder member is not loaded with a disc and put in the retracted position.
According to the present invention, yet furthermore, the holder member has a bottom portion able to come into contact with a bottom plate of the supporting frame so that an upper portion of the holder member is positioned inside of the supporting frame with the holder member being inclined when the holder member is not loaded with a disc and put in the retracted position.
