Description
【考案の詳細な説明】 〔概要〕 J字状の軸受だけで上下に開閉するカセット扉を脱落し
ないように軸支し、しかも該軸受に対する該軸の係合お
よび離脱を、通常の開閉動作では生じない該扉の水平且
つ上方への偏位状態で容易に行えるようにする。DETAILED DESCRIPTION OF THE INVENTION [Outline] A J-shaped bearing is used to axially support a cassette door that opens and closes vertically so that it does not fall off, and the engagement and disengagement of the shaft with respect to the bearing is performed by normal opening and closing operations. It is possible to easily perform the operation in a state where the door is not horizontally displaced and is displaced upward.
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.
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).

(2)が図の位置まで入ると弾性復帰して軸(2)の脱
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.
上述した軸受(5),(6)は左右非対称であるだけで
なく、成形用の金型構造が複雑になる。また、軸の取付
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.
本考案は、上下に開閉するカセット扉(1)の支持軸
(2)を該扉(1)の上端より所定寸法だけ下側に取付

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.
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).

ール部(12)で軸(2)を収容している。The cassette door 1 of the present invention supports the shaft 2 below the upper end by a predetermined size. That is, in FIG. 2 (b), the upper end of the door (1) is simply curled to accommodate the shaft (2).
In (b), a bent portion (11) is formed at the upper end, and the curl portion (12) below the bent portion (11) accommodates the shaft (2).

3)が形成してある。The bearing (7) has an inner L-shaped portion (71) and an intermediate J-shaped portion (7).
2) consists of an outer stopper (73), an intermediate J-shaped portion (72) rotatably supports the shaft (2), and an inner L-shaped portion (71) prevents the shaft (2) from coming off. . Stopper (7
3) is for preventing axial displacement of the shaft (2). The door (1) is provided with through holes (13), (1
3) is formed.

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.

らカセットパックで押されても脱落することはない。In the open state of (d), the shaft (2) side points downward, so the door (1) does not fall off, but even in the open state of (e), the bent portion (1)
Distance (E) between the upper edge of 1) and the inner surface of the front panel (4)
Is smaller than the distance (D) between the lower end of the shaft (2) and the upper end of the L-shaped portion (71), the door (1) will not fall off even if it is pushed by the cassette pack from the left side. .
以上述べたように本考案によれば、簡単な金型構造で軸
受部を製造することができ、しかも軸挿入の容易な寸法
にしても軸の支持強度を低下させることがない利点があ
る。As described above, according to the present invention, it is possible to manufacture the bearing portion with a simple mold structure, and there is an advantage that the bearing strength of the shaft is not reduced even if the shaft is easily inserted.
