DESCRIPTION:
BRIEF SUMMARY
This application was filed under 35 U.S.C. 371 and is a national stage filing based upon PCT/JP95/00978 filed May 22, 1995.
TECHNICAL FIELD
This invention relates to a recording and/or reproducing apparatus using a tape cassette as a recording medium. More particularly, this invention relates to a recording and/or reproducing apparatus such as a tape recorder, for example, in which a cassette holding mechanism is pivotably disposed, the apparatus including therein a recording and/or reproducing unit adapted for carrying out recording and/or reproduction of information signals with respect to a recording medium such as a magnetic tape, for example, accommodated within the tape cassette, the apparatus shaped to resemble a thin box with a planar rectangular surface to allow the cassette holding mechanism to hold the tape cassette to load (mount) the tape cassette into the recording and/or reproducing unit.
BACKGROUND ART
Hitherto, tape recorders using a tape cassette within which a recording medium such as a magnetic tape, for example, for recording information signals have been widely used. In such tape recorders, a cassette holder adapted so that a tape cassette is inserted thereinto and is held thereby (hereinafter simply referred to as "insertion-held" depending upon circumstances) pivotably disposed in the recorder body which also includes a recording/reproducing unit for carrying out recording/reproduction of information signals with respect to the magnetic tape accommodated within the tape cassette is provided. Thus, the tape cassette is insertion-held by the cassette holder and the cassette holder is pivotted to the recording/reproducing unit side disposed at the recorder body side, whereby the tape cassette is loaded (mounted) at a cassette loading portion constituted at the upper surface side of the recording/reproducing unit.
At the cassette loading portion, there are disposed a pair of reel drive shafts which are relatively engaged with a pair of tape reels on which a magnetic tape rotatably accommodated within the tape cassette is wound, a tape feed mechanism consisting of a capstan shaft and a pinch roller for moving the magnetic tape at a constant velocity, and a magnetic head for recording/reproducing information signals such as music signals, for example, with respect to the magnetic tape fed by the tape feed mechanism.
In this tape recorder, when the tape cassette is loaded into the cassette loading portion of the recording/reproducing unit, the reel drive shafts are engaged with the tape reels of the tape cassette side to rotationally operate the tape reels, and to allow the pinch roller to be in pressure-contact with the capstan shaft to move, at a constant velocity, the magnetic tape accommodated within the tape cassette to further allow the magnetic head to be in sliding contact with the magnetic tape so that recording/reproduction of information signals can be carried out.
The size of tape recorders have been miniaturized down to dimensions substantially equal to the outside shape of the tape cassette.
In the tape recorders of the kind conventionally used, the cassette holder for loading (mounting) the tape cassette into the cassette loading portion is of a structure that the tape cassette is inserted with one side of two opposing long sides being an insertion end. Namely, insertion/withdrawal (removal) of the tape cassette with respect to the cassette holder is carried out with the tape cassette being laterally disposed in such a manner that the lengthwise portion serves as the insertion end.
This is because since the tape cassette has an opening for facing a portion of the magnetic tape toward the external is formed at a side surface along one side of the two opposing long sides, the recording/reproducing unit of the tape recorder is constituted so that the magnetic head is advanced and withdrawn with respect to the exposed portion of the magnetic tape where the opening faces the magnetic head.
Further, in tape recorders adapted so that insertion/withdrawal of the tape cassette
