Figures 1 to 10 show different views of the assembly in which we can see the main elements that compose it.

Dans les dessins en question on peut voir que le support récepteur est constitué par la base (2) qui est dotée de la moulure antérieure (3) pourvue de l'ouverture d'entrée (4) et de la fenêtre (5).. In the drawings in question it can be seen that the receiving support consists of the base (2) which is provided with the front molding (3) provided with the inlet opening (4) and the window (5).

La base (2) en question est dotée des rebords latéraux
(6) dans lesquels ont été prévus les deux canaux de guidage (7) pourvus de gorges finales (8). L'un des rebords (6) est doté de la prolongation supérieure (9) dont une partie est affectée par la rainure (10), tandis que l'autre partie présente l'orifi- ce longitudinal (11) qui est aligné avec la rainure (10), étant prévu à l'extrémité un saillant qui constitue le crochet (12).The base (2) in question has side edges
(6) in which the two guide channels (7) are provided, provided with final grooves (8). One of the flanges (6) has the upper extension (9), part of which is affected by the groove (10), while the other part has the longitudinal orifice (11) which is aligned with the groove (10), being provided at the end with a projection which constitutes the hook (12).

Dans la prolongation supérieure (9) il a été prévu un élément éjecteur automatique qui est constitué par la tige (13), dont l'extrémité est dotée de la plaque (14) encastrée diamétralement et qui comporte à une extrémité le crochet (16), tandis que son autre extrémité est dotée de la butée (15). La tige en question (13) est logée dans l orifice longitudinal (11) de fason que la butée (15) émerge à travers la rainure (10) et que le crochet (16) reçoive 1 extrémité du ressort hélicoïdal (17), dont l'extrémité opposée est reliée au crochet (16) prévu dans le saillant de la prolongation supérieure(9). In the upper extension (9) there has been provided an automatic ejector element which is constituted by the rod (13), the end of which is provided with the plate (14) diametrically embedded and which comprises at one end the hook (16) , while its other end is provided with the stop (15). The rod in question (13) is housed in the longitudinal orifice (11) so that the stop (15) emerges through the groove (10) and that the hook (16) receives 1 end of the helical spring (17), of which the opposite end is connected to the hook (16) provided in the projection of the upper extension (9).

A la partie inférieure, la base (2) du réceptacle présente une paire de consoles (18) dans lesquelles est supporté le minimoteur (19) d'entrainement du ruban magnétique, qui est fixé sur le support (20) doté d'ergots qui, au moyen des goujons (22) s encastrent dans les consoles (18), étant ainsi relies à la base (2). At the bottom, the base (2) of the receptacle has a pair of brackets (18) in which is supported the minimotor (19) for driving the magnetic tape, which is fixed on the support (20) provided with lugs which , by means of studs (22) fit into the brackets (18), thus being connected to the base (2).

Le support du minimoteur (19) est doté d'une cavité (24) dans laquelle s'appuie le ressort hélicodal (25) qui, à son extrémité opposée s'appuie sur une autre cavité (26) prévue dans la base (2). Dans cette base (2) il est prévu un orifice (29) de passage de l'axe (27) de sortie du minimoteur (19), dont l'extrémité est dotée du galet (28) qui se place à la hauteur de l en- trée (4) de la cartouche. The minimotor support (19) is provided with a cavity (24) in which the helical spring (25) is supported which, at its opposite end is supported on another cavity (26) provided in the base (2) . In this base (2) there is provided an orifice (29) for passage of the axis (27) of the minimotor outlet (19), the end of which is provided with the roller (28) which is placed at the height of the inlet (4) of the cartridge.

Sur la partie externe des bords (6) de la base (2) ont été prévus des saillants cylindriques (30) qui constituent les axes d'articulation du dispositif d'enclenchement (31), lequel est constitué par une pièce en forme de U inversée avec une protubérance frontale (32) au centre et dont les extrémités présentent des prolongations postérieures (33) dont les pointes comportent des consoles (34) dotées d'entailles (36) et d'une cavité (35) en forme de demi-lune. Aux extrémités de la pièce en forme de U inversé ont été prévus des orifices de pivotement (37). On the outer part of the edges (6) of the base (2) are provided cylindrical projections (30) which constitute the axes of articulation of the latching device (31), which is constituted by a U-shaped part. inverted with a frontal protuberance (32) in the center and the ends of which have posterior extensions (33) the points of which include consoles (34) provided with notches (36) and a cavity (35) in the form of half Moon. Pivot holes (37) are provided at the ends of the inverted U-shaped part.

Le dispositif d'enclenchement (31) est disposé-par sa partie en forme de U inversé derrière la moulure #(3) de la base (2), avec la protubérance frontale (32) introduite dans la fenêtre (5), tandis que ses parties latérales se situent en dehors de la base (2), leurs orifices de pivotement (37) s'adaptant sur les saillants (30) qui constituent les axes d'articulation prévus sur les rebords latéraux (c) de la base (2), tandis que les consoles (34) des prolongations (33) situées sur la base (2) s'encastrent dans les gorges finales (8) prévues dans les canaux de guidage (7), avec leurs entailles (3U) dans ces gorges (8) tandis que dans les cavités en forme de demi-lune (35) s'encastre le ressort de torsion (39) qui s'appuie sur le saillant courbe (40) prévu entre les supports (18) du minimoteur (19).Dans ces conditions le dispositif est obligé à rester normalement en position d'enclenchement (figure 9), avec la protubérance (32) partiellement en dehors de la fenêtre (5). The latching device (31) is arranged by its inverted U-shaped part behind the molding # (3) of the base (2), with the front protuberance (32) introduced into the window (5), while its lateral parts are located outside the base (2), their pivoting holes (37) fitting onto the projections (30) which constitute the articulation axes provided on the lateral edges (c) of the base (2 ), while the brackets (34) of the extensions (33) located on the base (2) fit into the final grooves (8) provided in the guide channels (7), with their notches (3U) in these grooves (8) while in the half-moon shaped cavities (35) the torsion spring (39) is fitted which rests on the protruding curve (40) provided between the supports (18) of the minimotor (19) .In these conditions the device is forced to remain normally in the latching position (Figure 9), with the protrusion (32) partially outside the window (5).

Au-dessous de la base (2) est située la pièce de couver ture et de protection (41) convenablement fixée par des vis ou par d autres moyens. Below the base (2) is located the cover and protection part (41) suitably fixed by screws or by other means.

Les figures 3, 9 et 10 illustrent le mode de fonctionnement du support récepteur proposé, étant entendu que la cartouche de ruban magnétique (42) est du type cassette et est dotée de côtés renforcés (43), que la.base est dotée de bords pourvus de rainures (44) et que le système d entraînement du ruban est constitué par le galet (45) qui dépasse partiellement à travers l'ouverture frontale (46) de la cartouche. Figures 3, 9 and 10 illustrate the mode of operation of the proposed receiver support, it being understood that the magnetic tape cartridge (42) is of the cassette type and has reinforced sides (43), that the base has edges provided with grooves (44) and that the tape drive system is constituted by the roller (45) which partially protrudes through the front opening (46) of the cartridge.

La figure 8 représente le support en position normale. Figure 8 shows the support in normal position.

Le dispositif d'enclenchement est en position operative, étant soumis à la pression du ressort de torsion (39) et le minimoteur (19) est incliné vers l'intérieur, étanuégalement soumis à impression du ressort (25), et avec le galet (28) en ligne avec l'ouverture d'entrée (4) de la cartouche.The latching device is in the operative position, being subjected to the pressure of the torsion spring (39) and the minimotor (19) is inclined inward, etanually also subjected to printing of the spring (25), and with the roller ( 28) in line with the inlet opening (4) of the cartridge.

Dans la figure 9, la cartouche (42) a été introduite dans l'ouverture (4), de façon que les bords de la base de celle-ci soient guidés dans les canaux (7) qui orientent son déplacement. Lorsque l'on introduit la cartouche dans le réceptacle, la base de cette cartouche fait reculer le dispositif d'enclenchement (31) jusqu'à ce que les rainures (44) atteignent le lieu où se trouvent les consoles (34) qui, sous l'action du ressort de torsion(39)pénètrent dans la cavité (35) de ces rainures (44), en maintenant ainsi la cartouche dans sa position. La pénétration de la cartouche est limitée par la butée (15) de l'élé- ment éjecteur et la cartouche pousse cet élément vers l'avant en surmontant la force du ressort (17) qui est retenu.En même temps le galet d entraînement (45) du ruban magnétique entre en contact avec le galet (28) du minimoteur (19) qui est situé verticalement, en surmontant la force du ressort (25). Les têtes d'enregistrement ou de lecture, selon le cas, entrent en action, pour enregistrer ou pour effectuer la lecture du ruban magnétique. In Figure 9, the cartridge (42) has been introduced into the opening (4), so that the edges of the base thereof are guided in the channels (7) which direct its movement. When the cartridge is inserted into the receptacle, the base of this cartridge causes the latching device (31) to move back until the grooves (44) reach the place where the brackets (34) are located, which under the action of the torsion spring (39) penetrates into the cavity (35) of these grooves (44), thereby maintaining the cartridge in its position. The penetration of the cartridge is limited by the stop (15) of the ejector element and the cartridge pushes this element forward, overcoming the force of the spring (17) which is retained. At the same time the drive roller (45) the magnetic tape comes into contact with the roller (28) of the minimotor (19) which is located vertically, overcoming the force of the spring (25). The recording or reading heads, as the case may be, come into action, to record or to read the magnetic tape.

A la fin de l'opération d'enregistrement ou de lecture, en exerçant une légère pression sur la protubérance (32) du dispositif d'enclenchement (31) (figure 10), on fait basculer ce dispositif (31) autour des saillants cylindriques (30) et de cette façon, les consoles (34) sortent des canaux (7), libérant ainsi la cartouche qui, sous l'action du ressort (17) est expulsée par l'élément éjecteur. At the end of the recording or reading operation, by exerting a slight pressure on the protuberance (32) of the latching device (31) (FIG. 10), this device (31) is tilted around the cylindrical projections (30) and in this way, the brackets (34) come out of the channels (7), thus releasing the cartridge which, under the action of the spring (17) is expelled by the ejector element.

Par conséquent il s'agit d'un support pour cartouche de ruban magnétique du type cassette doté d'une nouvelle disposition constructive qui présente une série d'innovations qui lui assurent une suprématie technique et fonctionnelle par rapport à tous les systèmes connus de ce type de supports. Consequently it is a support for cartridge of magnetic tape of the cassette type endowed with a new constructive arrangement which presents a series of innovations which assure it a technical and functional supremacy compared to all known systems of this type. of supports.

Bien entendu, diverses modifications peuvent être apportées par 1 homme de l'art aux dispositifs ou procédés qui viennent d'être décrits uniquement à titre d exemple non limitatif sans sortir du cadre de l'invention. Of course, various modifications can be made by one skilled in the art to the devices or methods which have just been described only by way of nonlimiting example without departing from the scope of the invention.
