It is possible to easily perform the operation in a state where the door is not horizontally displaced and is displaced upward.

[Industrial application field]

本考案は上下に開閉するカセット扉の支持装置に関す
る。The present invention relates to a cassette door support device that opens and closes vertically.

[Conventional technology]

カセットデッキのパック挿入口を閉塞する防塵用のカセ
ット扉は一般に上端が軸支され、カセットパックで押す
と上方へ開き、該パックを排出すると下方へ閉じる内開
きの扉である。An upper end of a dustproof cassette door that closes the pack insertion port of the cassette deck is generally pivotally supported, and is an inward-opening door that opens upward when pushed by the cassette pack and closes downward when the pack is discharged.

パ）。(a) is an assembly drawing seen from the inside of the deck, (c) and (d) are its A,
FIG. The bearing (6) on the right side has a structure in which a round hole (62) for inserting a shaft is simply provided in the support body (61) ((63) is a stopper), while the bearing (5) on the left side is on the upper side. The structure is such that the shaft (2) is rotatably supported by the fixed piece (51) and the lower movable piece (52) ((53) is a stopper).

落を阻止する。The movable piece (52) has an appropriate elasticity and is displaced downward when the shaft (2) is pushed in the direction of the white arrow in (c) of the figure, but elastically returns when the shaft (2) reaches the position of the figure. To prevent the shaft (2) from falling off.

[Problems to be solved by the device]

上述した軸受（５），（６）は左右非対称であるだけで

作業を容易にする可動片（５２）の弾性は、支持強度を
低下させる原因になる。The bearings (5) and (6) described above are not only asymmetrical to the left and right, but also the mold structure for molding becomes complicated. Further, the elasticity of the movable piece (52) that facilitates the work of attaching the shaft causes a decrease in support strength.

本考案は、カセット扉側の構造を工夫することにより、
上述した問題点を解決しようとするものである。The present invention, by devising the structure of the cassette door side,
It is intended to solve the above-mentioned problems.

[Means for Solving the Problems]

み該軸（２）をＪ字状の軸受（７）に対し係合または離
脱させ得る構造としてなることを特徴とするものであ
る。According to the present invention, a support shaft (2) of a cassette door (1) which opens and closes vertically is attached to a lower side by a predetermined dimension from an upper end of the door (1), and the door (1) is horizontally displaced to be displaced upward. The structure is such that the shaft (2) can be engaged with or disengaged from the J-shaped bearing (7) only in the opened state.

[Action]

カセット扉の支持軸は、該扉の上端からある程度下方に
設けられていても、該扉の回転運動に支持を与えること

（又は離脱）させることができ、挿入後該軸が該軸受内
に落下すると、垂直状態（閉状態）はもとより、水平状
態（開状態）になっても脱落することがない。The support shaft of the cassette door does not provide any support to the rotational movement of the door, even if it is provided below the upper end of the door to some extent. When a bearing for axially supporting such a cassette door is formed into a J shape having an opening for inserting the shaft, the shaft is inserted into the bearing only when the door is horizontal and is displaced upward ( If the shaft falls into the bearing after insertion, it will not fall off not only in the vertical state (closed state) but also in the horizontal state (opened state).

押されたときは一般にこの状態以下の開きである。(c)-(e) is each C arrow view figure of (a), (c) is an insertion state figure of a door (1). At the time of insertion, the door (1) is pushed in the direction of the white arrow in a state where the door (1) is horizontally displaced and deflected upward, and then the shaft (2) is dropped so as to engage with the J-shaped portion (72).
(d) is the state after this drop, and when pushed by a cassette pack (not shown), the opening is generally below this state.
