が起こるという問題点があつた。 The applicant has previously proposed a small cassette and a small recording/reproducing apparatus using this small cassette. In the cassette mounting mechanism of this compact recording and reproducing device, if the cassette is accidentally inserted into the housing with its lid open and the housing is pushed down forcefully, the housing will move down to the lowest position and be locked. At this time, the cassette is not installed properly and is slightly lifted from the predetermined installation position, resulting in incomplete engagement of the reel drive system, making tape running unstable and causing problems in recording and playback. The dot was hot.
本考案は上記問題点を解決したものであり、以
下図面と共にその一実施例について説明する。 The present invention solves the above problems, and one embodiment thereof will be described below with reference to the drawings.

ネルである。 As shown in FIG. 1, the cassette housing 1 is supported by a pair of support arms 2 and 3 on the left and right sides, respectively, and as the arms 2 and 3 rotate, the cassette housing 1 moves to the raised position (cassette removal position) P shown by the solid line. It moves up and down between 1 and the lowered position (cassette installation position) P2 . The housing 1 is locked at position P2 with the claw 4 being engaged with the lock lever 5. The housing 1 consists of a holder member 6 and a top plate 7 shown in FIG. Further, 8 is a top panel of the recording/reproducing device, and 9 is a bottom panel.

８と同一高さとなる。 As shown in FIGS. 3A and 3B, the small cassette 10 includes a cassette housing 11 containing a magnetic tape, and
A lid 12 provided on the front side and normally closed
It becomes more. This lid 12 rotates between a closed lid position shown by a solid line in FIG.
It is held in each position by the action of the When this small cassette 10 is inserted with the lid closed into the housing at position P1 in the direction of arrow A and the housing 1 is pushed down in the direction of arrow B, the housing 1 reaches position P2 and is locked, and the cassette 10 is moved downward. During operation, the lid 12 is opened by the lid opening mechanism 13 and is properly installed in the mounting section 14, so that the top plate 7 is at the same height as the top panel 8.

時には開口１５を通つて装置内に進入する。 Now, to explain the main part of the present invention, the upper front edge 8a in the direction of arrow A facing the opening 15 in the top panel 8 is the lid that is open when the cassette 10 is inserted into the housing 1. It is facing 12. Further, a rib 16 is provided in the lower surface of the top plate 7 in the vicinity of the upper end in the direction of arrow A to project downwardly. This rib 16
is opposite to the opening 15 and to the lid 12 which is open in the inserted state. In particular, since the rib 16 faces the opening 15, it enters the apparatus through the opening 15 when the cassette is normally installed.

従つてカセツト１０を蓋１２を開いた状態でハウ
ジング１内に挿入した場合でのカセツト装着は確
実に防止される。 If the small cassette 10 is accidentally inserted into the housing 1 with the lid 12 open, the cassette 10 will be inserted into the housing 1 in the same way as if the lid 12 was closed, as shown by the two-dot chain line in FIG. Then, the lid 12 enters below the rib 16 and above the edge 8a. Lid 12 and rib 16 and lid 12 and edge 8
The relative positional relationship with a is as shown in FIGS. 1 and 2. When the housing 1 is pushed down in the direction of arrow B in this state, when it is pushed down halfway, the lid 12 collides with the edge 8a and is opened a little further, as shown in FIG. will be pressed. That is, even when the housing 1 is pushed down strongly, the ribs 16 will not touch the upper panel edge 8.
The housing presses against the lid 12 that is locked in position a, and its downward movement is restricted to a position just before position P2 . (It moves down to position P 2 and becomes locked). Therefore, the housing 1 is not locked and rises to position P1 when the pressing force is released.
Therefore, when the cassette 10 is inserted into the housing 1 with the lid 12 open, attachment of the cassette is reliably prevented.
また上記の場合にハウジング１を強く押し下げ
ても、蓋１２は破損しない。 Further, even if the housing 1 is strongly pushed down in the above case, the lid 12 will not be damaged.
上述の如く、本考案になるカセツト誤装着防止
機構によれば、誤つてカセツトの蓋を開いたまま
の状態でカセツトを装着しようとした場合に、蓋

ハウジングがそれ以上下動することを制限するこ
とが出来る。 As described above, the cassette misloading prevention mechanism of the present invention prevents the lid from coming into contact with the opening edge of the top panel when a cassette is accidentally loaded when the cassette lid is left open. According to
Further downward movement of the housing can be restricted.
また天板の下方突起が上記蓋に押し当たり、蓋
を受けることにより、蓋が無理やり回動されてし
まうことを制限し得る。 Further, the lower protrusion of the top plate presses against the lid and receives the lid, thereby preventing the lid from being forced to rotate.

実に制限することが出来、カセツトの蓋が開いた
ままの状態で装着されてしまうことになる誤装着
を確実に防止することが出来るという特長を有す
る。 As a result, even if the housing is pushed down strongly, the downward movement of the housing can be reliably restricted at an intermediate position, preventing incorrect installation of the cassette with the lid open. It has the advantage of being able to reliably prevent this.
