Description
La présente invention se rapporte à un dispositif d'insertion et d'éjection de cassettes
pour appareil d'enregistrement et de lecture à bande magnétique.
Elle s'applique aux dispositifs du genre comprenant un châssis fixe avec deux montants latéraux disposés parallèlement l'un à l'autre et dans les-
<EMI ID=1.1>
lesquelles s'introduisent des tétons portés par un magasin recevant la cassette de manière à assurer
au magasin et à la cassette un mouvement horizontal
<EMI ID=2.1>
sur les moyens d'entraînement et de lecture de la
bande magnétique montés sur une plaque de base du châssis fixe.
L'invention a pour but la réalisation d'un appareil de ce genre se distinguant par un guidage parfait de la cassette dans son mouvement d'insertion, de mise en position opérative et d'éjection par
une mécanique très simple vis-à-vis d'appareils qui, tout en prévoyant des systèmes de fentes de guidage latérales, comprennent des châssis mobiles notamment
un châssis mobile porteur des organes d'entraînement
et de lecture ou un châssis d'éjection.
Le dispositif objet de l'invention se distingue essentiellement en ce que latéralement par rapport à chaque montant est prévue une simple plaque mobile comprenant au moins deux fentes inclinées et parallèles dans lesquelles s'introduisent également
les tétons du magasin, les deux plaques mobiles
étant rendues solidaires l'une de l'autre dans leurs mouvements de manière à en lier rigidement le mouvement lors de l'insertion ou de l'éjection de la
cassette et en ce que l'on prévoit des moyens par lesquels pendant les opérations d'insertion ou d'éjection les plaques mobiles sont soumises chacune à un mouve-ment de va-et-vient rectiligne suivant le plan d'insertion de la cassette.
Dans la réalisation pratique de l'invention, chacune des plaques mobiles est munie d'une crémaillère qui est en prise avec un engrenage dont au moins un comporte un excentrique auquel sont attachés des moyens élastiques, par exemple un ressort, reliés
<EMI ID=3.1>
se référant aux dessins dans lesquels :
Les figures 1A, 1B et 1C sont des vues latérales explicatives.
La figure 2 est une vue en plan. La figure 3 est une vue partielle en perspective éclatée.
Sur les dessins ci-joints on a représenté en 10 le châssis de l'appareil comprenant une plaque de base fixe 11 sur laquelle sont montés les moyens d'entraînement et de lecture de la bande magnétique.
De cette plaque de base sont solidaires deux montants latéraux 12 en forme de plaques disposés parallèlement l'un par rapport à l'autre.
Dans ces montants sont pratiquées des fentes 14 en forme de L inversé.
Le magasin 18 recevant la cassette 20 porte
<EMI ID=4.1>
14 de façon à assurer au magasin ainsi qu'à la cassette un mouvement horizontal puis vertical pour positionner la cassette sur les moyens d'entraînement et de lecture de la bande magnétique.
Conformément à l'invention, on prévoit latéralement par rapport à chaque montant 12 une
<EMI ID=5.1>
Chaque plaque mobile 22 comprend sur son bord inférieur une crémaillère 26 avec laquelle est <EMI ID=6.1>
en prise un engrenage 28 porté par un axe de rotation
<EMI ID=7.1>
Les deux plaques mobiles 22 coopèrent donc avec deux engrenages 28 qui sont identiques et rendus solidaires entre eux car montés sur le même axe de rotation 30.
Un des engrenages 28 comporte un plateau
<EMI ID=8.1>
un ressort 34 dont l'autre extrémité est reliée à un rebord vertical 36 du châssis 10.
Chacune des plaques mobiles 22 comprend deux fentes 24 inclinées et parallèles au travers desquelles passent les tétons 15 du magasin 18.
Dans ces conditions les plaques mobiles latérales 22, solidaires l'une de l'autre dans leurs mouvements, coopèrent avec les tétons 16 du magasin
18 de façon' en lier rigidement le mouvement lors de l'insertion et de l'éjection de la cassette 20.
Lors de l'insertion de la cassette 20,
les plaques mobiles 22 sont déplacées sous la commande du mouvement du magasin 18 et donc do la cassette 20 et cette dernière est descendue sur les organes d'entraînement et de lecture. Ce déplacement des plaques mobiles rendu possible grâce aux fentes
<EMI ID=9.1>
direction suivant le plan d'insertion de la cassette.
D'autre part, le déplacement des plaques
<EMI ID=10.1>
de mettre sous tension le ressort 34.
La commande de 1'éjection s'effectue en

The present invention relates to a device for inserting and ejecting cassettes
for tape recording and playback apparatus.
It applies to devices of the kind comprising a fixed frame with two lateral uprights arranged parallel to one another and in the-
<EMI ID = 1.1>
which introduce nipples carried by a magazine receiving the cassette so as to ensure
horizontal movement in store and cassette
<EMI ID = 2.1>
on the means of training and reading the
magnetic strip mounted on a base plate of the fixed chassis.
The object of the invention is to produce an apparatus of this kind which is distinguished by perfect guiding of the cassette in its movement of insertion, putting into operative position and ejection by
very simple mechanics vis-à-vis devices which, while providing lateral guide slot systems, include movable frames in particular
a movable chassis carrying the drive members
and read or eject chassis.
The device object of the invention is essentially distinguished in that laterally with respect to each upright is provided a simple movable plate comprising at least two inclined and parallel slots into which are also introduced
the store nipples, the two movable plates
being made integral with one another in their movements so as to rigidly link the movement when inserting or ejecting the
cassette and in that means are provided by which, during the insertion or ejection operations, the movable plates are each subjected to a rectilinear back-and-forth movement along the cassette insertion plane .
In the practical embodiment of the invention, each of the movable plates is provided with a rack which is engaged with a gear, at least one of which comprises an eccentric to which elastic means, for example a spring, are attached, connected
<EMI ID = 3.1>
referring to the drawings in which:
Figures 1A, 1B and 1C are explanatory side views.
Figure 2 is a plan view. Figure 3 is a partial exploded perspective view.
The accompanying drawings show at 10 the chassis of the device comprising a fixed base plate 11 on which are mounted the means for driving and reading the magnetic tape.
Two lateral uprights 12 in the form of plates are fixed to this base plate, arranged parallel to one another.
In these uprights are made slots 14 in the shape of an inverted L.
The magazine 18 receiving the cassette 20 carries
<EMI ID = 4.1>
14 so as to provide the magazine and the cassette with a horizontal and then vertical movement in order to position the cassette on the means for driving and reading the magnetic tape.
According to the invention, there is provided laterally with respect to each upright 12 a
<EMI ID = 5.1>
Each movable plate 22 comprises on its lower edge a rack 26 with which is <EMI ID = 6.1>
in engagement a gear 28 carried by an axis of rotation
<EMI ID = 7.1>
The two movable plates 22 therefore cooperate with two gears 28 which are identical and made integral with one another because they are mounted on the same axis of rotation 30.
One of the gears 28 has a plate
<EMI ID = 8.1>
a spring 34, the other end of which is connected to a vertical flange 36 of the chassis 10.
Each of the movable plates 22 comprises two inclined and parallel slots 24 through which the pins 15 of the magazine 18 pass.
Under these conditions the lateral movable plates 22, integral with one another in their movements, cooperate with the pins 16 of the magazine
18 so as to rigidly link the movement thereof during the insertion and ejection of the cassette 20.
When inserting the cassette 20,
the movable plates 22 are moved under the control of the movement of the magazine 18 and therefore do the cassette 20 and the latter is lowered onto the drive and reading members. This movement of the movable plates made possible by the slots
<EMI ID = 9.1>
direction according to the cassette insertion plane.
On the other hand, the displacement of the plates
<EMI ID = 10.1>
energize the spring 34.
The ejection control is carried out in
<EMI ID = 11.1>
<EMI ID = 12.1>
<EMI ID = 13.1>
<EMI ID = 14.1>
<EMI ID = 15.1>
