本考案はカセツトプレーヤのカセツト挿入口に
取付けられるダストカバーの開閉を制御する機構
に関する。[Detailed Description of the Invention] Industrial Application Field The present invention relates to a mechanism for controlling the opening and closing of a dust cover attached to a cassette insertion slot of a cassette player.
従来の技術
カセツトプレーヤのカセツト挿入口には防塵効
果と意匠を兼ねたダストカバーが取付けられてい
るが、一般的にはいかなる場合でも開閉自在であ
る。BACKGROUND ART A dust cover is attached to the cassette insertion slot of a cassette player to have both a dustproof effect and a design, but it can generally be opened and closed in any case.
考案が解決しようとする問題点
そのため、異物がカセツトプレーヤ内に混入さ
れ易い。更にカセツトの厚みは部分的に異なつて
おり、カセツトの挿入方向は予め定められている
が、カセツトが誤つた方向から挿入される恐れも
ある。Problems to be Solved by the Invention As a result, foreign objects are likely to get mixed into the cassette player. Furthermore, the thickness of the cassette differs in some parts, and although the insertion direction of the cassette is predetermined, there is a risk that the cassette may be inserted from the wrong direction.
本考案はこのような問題点を解決しようという
ものである。 The present invention is intended to solve these problems.

カバーの開閉制御機構を特徴とする。Means for Solving the Problems In order to solve the above problems, the present invention provides a mechanism for controlling the opening and closing of the dust cover attached to the cassette insertion slot of a cassette player, which normally protrudes into the cassette insertion slot and has a includes a cam that engages with the dust cover to restrict opening and closing of the dust cover, and is configured to release the engagement with the dust cover when the cam is pushed up; is provided at a position where the thick wall portion of the cassette normally passes through, and the height from the lower end of the cassette insertion opening to the cam is greater than the thickness of the thin wall portion of the cassette and smaller than the thickness of the thick wall portion of the cassette. It features a dust cover opening/closing control mechanism.
作 用
カセツト未装着状態では、カムの一部がダスト
カバーと係合してダストカバーの開閉動作を阻止
するが、カセツトを挿入するとき、カセツトによ
りカムがカセツトプレーヤ内部へ押し上げられる
とカムとダストカバーとの係合状態がはずれ、ダ
ストカバーの開閉が自由になり、カセツトをカセ
ツトプレーヤに装着できる。Function When a cassette is not installed, a part of the cam engages with the dust cover and prevents the dust cover from opening and closing, but when the cassette is inserted and the cam is pushed up into the cassette player, the cam and dust The engagement state with the cover is released, the dust cover can be opened and closed freely, and the cassette can be attached to the cassette player.
従つて、カセツト未装着状態のときダストカバ
ーは開閉できず、異物の混入が防止される。更に
カムが厚肉部のみと当接するようカムをカセツト
の厚肉部が正規に通過する位置に設け、且つ挿入
口下端からカムまでの高さを工夫しているので、
誤つた方向からカセツトを挿入してもカムと当接
せず、ダストカバーは開閉しないので、カセツト
の誤挿入も防止できる。 Therefore, the dust cover cannot be opened or closed when the cassette is not installed, thereby preventing foreign matter from entering. Furthermore, the cam is placed in a position where the thick part of the cassette normally passes through so that the cam contacts only the thick part, and the height from the lower end of the insertion slot to the cam is carefully designed.
Even if the cassette is inserted from the wrong direction, it will not come into contact with the cam and the dust cover will not open or close, so incorrect insertion of the cassette can be prevented.
考案の実施例
以下、図面を参照して本考案の実施例につき説

ある。 FIG. 1 is a sectional view showing an embodiment of the present invention, with no cassette attached. FIG. 2 is an exploded perspective view of the main part, and FIG. 3 is a sectional view when the cassette is installed. Reference numeral 1 denotes a front plate of the cassette player, in which a cassette insertion opening 2 is formed. An elongated through hole 3 is formed in the upper part of the cassette insertion opening 2, and a bearing part 10 is provided at the back. A dust cover 4 has a shaft 5 and a protrusion 6 formed on the top thereof, and is rotatable about the shaft 5 attached to a bearing 10.
尚、突起６のかわりにダストカバー４の上辺を
全て突出させてもよい。 Incidentally, instead of the protrusion 6, the entire upper side of the dust cover 4 may be made to protrude.

る。 A cam 7 slides up and down inside the through hole 3. A stopper 8 is provided on the cam 7 so as to protrude toward the dust cover 4 side. Reference numeral 9 denotes an elastic body such as a spring, which is fixed inside the upper part of the front plate 1 and presses the cam 7 toward the cassette insertion slot 2. 11 is a cassette, and 12 is its thick part. The relationship between the height H 0 from the lower end of the cassette insertion slot 2 to the lower end of the cam 7, the general thickness H 1 of the cassette 11 (i.e., the thin part), and the thickness H 2 of the thick part 12 is expressed by equation (1). It is set as follows.
H2＜H0＜H1 ……(1) 以下、本実施例の動作について説明する。 H 2 <H 0 <H 1 (1) The operation of this embodiment will be described below.
カセツトパツクがカセツトプレーヤ内に未装着

つて、ダストカバー４は開かない。カセツト装着
時には第３図に示すようにカセツト１１の厚肉部
１２がカセツト挿入口２に突出しているカム７を

る。カセツト１１がカセツトプレーヤ内に装着さ
れるとダストカバー４はその下端がカセツト１１
の上端に接して、ある角度で開いた状態を維持す
る。 When the cassette pack is not installed in the cassette player, the dust cover 4 is closed as shown in FIG. At this time, the stopper 8 of the cam 7 faces the protrusion 6 of the dust cover 4 while maintaining substantially contact therewith. Therefore, even if the dust cover 4 attempts to rotate clockwise, the protrusion 6 engages with the stopper 8 and the rotation is prevented. Therefore, the dust cover 4 will not open. When the cassette is installed, the thick wall portion 12 of the cassette 11 pushes up the cam 7 projecting into the cassette insertion opening 2, as shown in FIG. As a result, the stopper 8 of the cam 7 also moves upward and the engagement with the protrusion 6 of the dust cover 4 is released, so that the dust cover 4 can be freely opened and closed, and the cassette 11 can be inserted. When the cassette 11 is installed in the cassette player, the lower end of the dust cover 4 is attached to the cassette 11.
It touches the top edge of and remains open at an angle.
これにより、ストツパ８の斜面８′が突起６に
係合してカム７は第１図に示す位置まで下がり得
ない。（第３図に示す位置より若干下がるだけで
ある。）従つて、カム７はカセツト１１の排出を
妨げない。 As a result, the slope 8' of the stopper 8 engages with the protrusion 6, and the cam 7 cannot be lowered to the position shown in FIG. (It is only slightly lower than the position shown in FIG. 3.) Therefore, the cam 7 does not prevent the ejection of the cassette 11.
以上のようにカセツト未装着状態ではダストカ
バーの開閉が規制されるため、異物の混入を防止
できる。 As described above, since opening and closing of the dust cover is restricted when no cassette is installed, it is possible to prevent foreign matter from entering.
本考案は更にカセツトの誤挿入をも防止できる
ものである。即ち、第３図はカセツト１１を厚肉

となり、万一カセツト１１を厚肉部１２とは異な
る３方向から誤挿入した場合、カム７を上方へ押
し上げることができないため、ダストカバー４は
開かない。 The present invention also prevents incorrect insertion of the cassette. That is, although FIG. 3 shows a so-called horizontal insertion type cassette player in which the cassette 11 is inserted from the thick part 12, in this embodiment, the height H 0 of the cam 7 is set to H 2 as in the above-mentioned equation (1). Since it is set as <H 0 <H 1 , the cam 7 can only come into contact with the thick wall portion 12, and if the cassette 11 is incorrectly inserted from three directions different from the thick wall portion 12, the cam 7 will The dust cover 4 cannot be opened because it cannot be pushed upward.
また、カセツトの厚肉部を右又は左にして挿入
するいわゆる縦挿入型のカセツトプレーヤの場
合、カムを厚肉部が通過する位置に設ければよ
い。例えばカセツトの厚肉部を右側にして挿入す
るものであれば、第４図に正面図で示すようにカ
ム７をカセツト１１の厚肉部１２に対応してカセ
ツト挿入口２の右側に突出させておけばよい。 Further, in the case of a so-called vertical insertion type cassette player in which the cassette is inserted with the thick wall portion on the right or left side, the cam may be provided at a position where the thick wall portion passes through. For example, if the cassette is to be inserted with the thick wall part on the right side, the cam 7 should be projected to the right side of the cassette insertion slot 2 in correspondence with the thick wall part 12 of the cassette 11, as shown in the front view in FIG. Just leave it there.
このように、カムの高さを(1)式の如く設定し、
且つカセツトの厚肉部が通過する位置にカムを取
付けることにより、異物の混入だけでなく、カセ
ツトの誤挿入をも防止できる。 In this way, the height of the cam is set as shown in equation (1),
Furthermore, by attaching the cam at a position through which the thick portion of the cassette passes, it is possible to prevent not only foreign matter from entering the cassette but also erroneous insertion of the cassette.
考案の効果
以上、詳細に説明したように、本考案によれば
カセツト未装着状態ではダストカバーが開かない
よう構成されているため、異物の混入が防止でき
