る。[Detailed description of the invention] [Industrial application] This invention is based on the idea that when a cassette is horizontally pushed into a movable member from the side of a tape recorder such as a car stereo, the movable member into which the cassette has been pushed returns to the cassette set position. This invention relates to a cassette popping-out prevention device for preventing the cassette from jumping out of the moving member and falling when the cassette is ejected, in a tape recorder that moves or moves the moving member from the cassette setting position to the cassette pushing position to eject the cassette. It is something.

れについて説明する。
This type of cassette ejection prevention device in a conventional tape recorder and the direction of movement of the cassette during ejection are shown in FIGS. 3 to 5, and will be described below.
２はカセツト３が押し込まれる移動部材で、内
方に突条部１ａを曲設した板バネ１が移動部材２
にカシメ２ａで取り付けられている。 Reference numeral 2 denotes a moving member into which the cassette 3 is pushed, and the leaf spring 1 with the protruding portion 1a bent inward is the moving member 2.
It is attached with caulking 2a.
このカセツト押し込み位置に位置する移動部材

条部１ａがカセツト３に押しのけられ、突条部１
ａと移動部材２とでカセツト３を挟み込む状態と
なる。 When the cassette 3 is pushed into the moving member 2 located at this cassette pushing position, the protrusion 1a of the leaf spring 1 is pushed away by the cassette 3, and the protrusion 1a is pushed away by the cassette 3.
The cassette 3 is sandwiched between the moving member a and the moving member 2.
そして、カセツト３が移動部材２の奥に当たつ
た後もカセツト３の押し込みが継続されると、移
動部材２は内部機構によつてテープを駆動できる
位置（カセツトセツト位置）にカセツト３をセツ
トする。 If the cassette 3 continues to be pushed in even after the cassette 3 hits the back of the moving member 2, the moving member 2 uses an internal mechanism to set the cassette 3 in a position where it can drive the tape (cassette set position). do.
すなわち、この時の移動部材２の運動は、第５
図のカセツト３の挿入方向ａと、カセツト３をセ
ツトするための下降方向ｂとの合成運動である。 That is, the movement of the moving member 2 at this time is the fifth
This is a composite movement of the insertion direction a of the cassette 3 shown in the figure and the downward direction b for setting the cassette 3.
この逆に、カセツト３をイジエクトするために
イジエクト操作を行なうと、移動部材２はカセツ
トセツト位置からの上昇方向ｄとイジエクト方向
ｃとの合成方向の運動を行なうため、カセツト３
は方向ｅの慣性力を受けることとなる。 Conversely, when an eject operation is performed to eject the cassette 3, the movable member 2 moves in the composite direction of the upward direction d from the cassette set position and the eject direction c.
will be subjected to an inertial force in the direction e.
この時、板バネ１は移動部材２との挟持力で、
慣性力によつてカセツト３が移動部材２から飛び
出して落下するのを防止している。 At this time, the leaf spring 1 has a clamping force with the moving member 2,
The inertial force prevents the cassette 3 from jumping out from the moving member 2 and falling.
この板バネ１による挟持力が弱いと、イジエク
ト時にカセツト３が移動部材２から飛び出してし
まう。
If the clamping force of the leaf spring 1 is weak, the cassette 3 will fly out from the moving member 2 at the time of ejection.
また、逆に板バネ１による挟持力が強すぎる
と、カセツト３が完全に移動部材２に押し込まれ
ないうちに板バネ１の抵抗で移動部材２が移動し
てしまうので、カセツト３のセツトができなくな
り、押し込みフイーリングも悪くなる。 On the other hand, if the clamping force of the leaf spring 1 is too strong, the resistance of the leaf spring 1 will cause the movable member 2 to move before the cassette 3 is completely pushed into the movable member 2, making it difficult to set the cassette 3. It becomes impossible to do so, and the push-in feeling becomes worse.
そして、板バネ１は金属製であるため、合成樹
脂製のカセツト３を傷付ける恐れもあり、さらに
板バネ１の曲げ形状が複雑で、板厚や硬度のばら
つきなどで荷重管理が困難であるなどの不都合が
あつた。 Since the leaf spring 1 is made of metal, there is a risk of damaging the cassette 3, which is made of synthetic resin.Furthermore, the bending shape of the leaf spring 1 is complicated, and load management is difficult due to variations in plate thickness and hardness. There were some inconveniences.
この考案は、上記したような不都合を解消する
ためになされたもので、カセツトの押し込み時に
は押し込みに対する抵抗を少なくして押し込みフ
イーリングをよくする。
This invention was made to solve the above-mentioned problems, and when pushing the cassette, the resistance to pushing is reduced to improve the pushing feeling.
そして、イジエクト時にはカセツトの摺動阻止
力を増加させてカセツトの移動部材からの飛び出
しを完全に防止するとともに、その製作および管
理を行ない易くすることを目的とするものであ
る。 The purpose of this invention is to increase the sliding prevention force of the cassette at the time of ejection to completely prevent the cassette from jumping out from the moving member, and to facilitate the manufacture and management of the cassette.
この考案は、上記した目的を達成するため、移
動部材がカセツト押し込み位置からカセツトをセ
ツトするためにカセツトセツト位置方向に移動す

セツトとの摩擦力が増加する摩擦部材を移動部材
に設けたものである。
In order to achieve the above-mentioned purpose, this invention has been developed because when the movable member moves from the cassette push-in position toward the cassette set position in order to set the cassette, the frictional force with the cassette decreases, and the movable member ejects the cassette. The movable member is provided with a friction member that increases the frictional force with the cassette when it reaches the cassette push-in position from the cassette set position.
以下、この考案の一実施例を第１図および第２
図に基づいて説明する。
An example of this invention is shown below in Figures 1 and 2.
This will be explained based on the diagram.
４はカセツト３が押し込まれる移動部材を示
し、その上面には、移動部材４の内面よりも上方
に内面が位置し、かつ、移動部材４がカセツト押
し込み位置（イジエクト位置）に到達したときに
回動阻止部材としてのホルダ５に近接する位置に
支持部４ａが形成され、この支持部４ａにゴムな
どの摩擦部材としての弾性摩擦リング６が回動可
能に嵌められている。 Reference numeral 4 indicates a movable member into which the cassette 3 is pushed, the inner surface of which is located above the inner surface of the movable member 4, and which rotates when the movable member 4 reaches the cassette push-in position (eject position). A support portion 4a is formed at a position close to the holder 5 as a movement preventing member, and an elastic friction ring 6 as a friction member made of rubber or the like is rotatably fitted into the support portion 4a.
したがつて、弾性摩擦リング６は支持部４ａ上
を自由に回動できるが、移動部材４がイジエクト
位置に到達すると、弾性摩擦リング６は支持部４
ａとホルダ５との間に挟み込まれ、回動しにくく
なる。 Therefore, the elastic friction ring 6 can freely rotate on the support part 4a, but when the moving member 4 reaches the eject position, the elastic friction ring 6 moves on the support part 4a.
It is caught between a and the holder 5, making it difficult to rotate.
このため、第２図に示すように、移動部材４が
イジエクト位置に移動し、カセツト３が第５図の
慣性力の方向ｅに力を受けると、弾性摩擦リング
６は回動せず、かつ、変形してカセツト３に対す
る摩擦力を強めるので、イジエクト動作の慣性に
よつてカセツト３が移動部材４から飛び出すのを
確実に防止できるため、カセツト３が移動部材４
から飛び出す恐れがなくなる。 Therefore, as shown in FIG. 2, when the movable member 4 moves to the eject position and the cassette 3 receives a force in the direction of inertial force e in FIG. 5, the elastic friction ring 6 does not rotate and , deforms and strengthens the frictional force against the cassette 3, thereby reliably preventing the cassette 3 from jumping out from the movable member 4 due to the inertia of the eject operation.
There is no fear of it jumping out.
これに対し、カセツト３の押し込み時にはカセ
ツト３と弾性摩擦リング６との摩擦力が強すぎる
と、第１図に示すように、その抵抗によつて移動
部材４、すなわち支持部４ａがホルダ５から離れ
るので、弾性摩擦リング６が円形に戻つて支持部
４ａ上を回動するために抵抗が減少し、カセツト
３の押し込みを楽に行なわせることができる。 On the other hand, if the frictional force between the cassette 3 and the elastic friction ring 6 is too strong when the cassette 3 is pushed in, as shown in FIG. Since they are separated, the elastic friction ring 6 returns to its circular shape and rotates on the support portion 4a, reducing resistance and allowing the cassette 3 to be pushed in easily.
なお、弾性摩擦リング６の断面は、円形の他、
四角形やその他の多角形でも同様に作用する。 Note that the cross section of the elastic friction ring 6 is not only circular but also
It works similarly for squares and other polygons.
以上のように、この考案によれば、移動部材に
カセツトを押し込む場合、カセツトとの間で摩擦
抵抗を生ずる摩擦部材には、摩擦抵抗を減少させ
る作用が生じる。
As described above, according to this invention, when a cassette is pushed into a moving member, the friction member that generates frictional resistance with the cassette has an effect of reducing the frictional resistance.
これに対し、イジエクト時には、移動部材から
カセツトが飛び出そうとするのに対し、摩擦部材
にはカセツトに対する摩擦抵抗が増加するような
作用が働くので、カセツトの飛び出しを確実に防
止することができる。 On the other hand, when the cassette is ejected, the cassette tends to pop out from the moving member, but the friction member acts to increase the frictional resistance against the cassette, so that the cassette can be reliably prevented from popping out.
そして、摩擦部材をゴムなどの柔軟材で構成す
ると、カセツトの表面に傷を付けたり、摩耗粉の
発生を防止することができる。 If the friction member is made of a flexible material such as rubber, it is possible to prevent the surface of the cassette from being scratched and generation of abrasion powder.
さらに、カセツトの押し込み時には、前述のよ
うに摩擦抵抗が減少するので、良好な押し込みフ
イーリングを得ることができる。 Furthermore, when the cassette is pushed in, the frictional resistance is reduced as described above, so that a good pushing feeling can be obtained.
しかも、挿入時とイジエクト時との摩擦抵抗が
相違するため、荷重管理の厳密さを必要とせず、
不良品の発生も少ないので、安価で確実なカセツ
トの飛び出し防止装置を提供することができる。 Moreover, since the frictional resistance is different during insertion and ejection, there is no need for strict load management.
Since there are fewer defective products, an inexpensive and reliable cassette popping-out prevention device can be provided.
