The above additional movement of the magnetic head has the drawback of being carried out by a complex linkage controlled by a mechanical keyboard. A magnet phone described in US-A-3,685,836 is known in the prior art. comprising magnetic card holder, the displacement of which relative to the read head is carried out manually. Finally, US-A-3,731,006 describes a card magnesium telephone comprising in particular means for automatic selection of the magnetic tracks.
L'invention a pour objectif de pallier les incon nients énoncés ci-dessus au niveau des déplacements respect du chariot porte-carte magnétique et de la tête magnétique.The invention aims to overcome the drawbacks mentioned above in terms of movement respect for the magnetic card holder carriage and the magnetic head.

10 A cet effet, la présente invention a pour objet magnétophone du type énoncé au début de la présente descr tion. L'invention se distinque en ce qu'elle comporte moyens de déplacement du chariot porte-carte adaptés p assurer son adressage automatique par rapport à la tête mag " tique suivant l'un quelconque des deux sens opposés de son de déplacement.To this end, the present invention relates to a tape recorder of the type stated at the beginning of this description. The invention is distinguished in that it comprises means for moving the card-holder carriage adapted to ensure its automatic addressing with respect to the magic head in any one of the two opposite directions of its movement.
Selon une autre caractéristique du magnétophone de présente invention, ledit système de guidage de la tête mag tique comporte au moins une extension au delà de la zone 20 déplacement de ladite carte, l'un au moins des détecteurs position étant un détecteur de fin de piste magnétique auto sant le passage vers ladite extension.According to another characteristic of the tape recorder of the present invention, said system for guiding the magic head comprises at least one extension beyond the displacement zone of said card, at least one of the position detectors being an end of track detector magnetic self sant passage to said extension.
Un autre objectif de l'invention est de permettre exploitation rationnelle et étendue du magnétophone. 25 Cet objectif est atteint en dotant le magnétoph d'un asservissement des déplacements respectifs du char porte-carte magnétique et de la tête magnétique qui peut ê soit direct, soit pris en charge automatiquement par des moy programmables. 30 Avantageusement, selon une autre caractéristique magnétophone, les moyens programmables comprennent un mic processeur pour le pilotage d'éléments électro-mécaniques commande desdits déplacements, et des moyens adaptés pour dialogue inter-actif du type conversationnel entre le mic " processeur et l'utilisateur permettant une programmation actions voulues.Another objective of the invention is to allow rational and extensive exploitation of the tape recorder. 25 This objective is achieved by providing the magnetoph with a servo-control of the respective displacements of the magnetic card-holding tank and of the magnetic head which can be either direct or taken care of automatically by programmable means. Advantageously, according to another tape recorder characteristic, the programmable means comprise a mic processor for piloting electro-mechanical elements controlling said displacements, and means adapted for interactive dialogue of the conversational type between the mic "processor and the user allowing programming of desired actions.
D'autres caractéristiques et avantages du magné phone de la présente invention ressortiront de la descript qui va suivre, donnée uniquement à titre d'exemple et faite référence aux dessins sur lesquels:Other characteristics and advantages of the magneto phone of the present invention will emerge from the description. which will follow, given solely by way of example and with reference to the drawings in which:

- la figure 5 est une vue du magnétophone se l'invention pour son exploitation rationelle et étendue.- Figure 5 is a view of the tape recorder according to the invention for its rational and extensive operation.
Ainsi qu'on peut le voir sur la figure 1, le magné phone selon l'invention comporte un chariot porte-carte mobile suivant l'axe Y et un système de guidage (2) d'une t magnétique (3) mobile selon l'axe X perpendiculaire à l'axe Sur le chariot porte-carte (1) , une carte magnétique (4) positionnée et maintenue en position par des moyens de v rouillage connus tels que décrit dans le brevet FR 1.591. précité. Le déplacement du chariot porte-carte (1) est as jetti à un moteur (5) du type pas à pas par l'intermédia d'un couplage (6) réalisé par courroie plate crantée en po uréthane armée fils d'acier.As can be seen in Figure 1, the magnéphone according to the invention comprises a mobile card holder carriage along the Y axis and a guide system (2) of a magnetic t (3) movable along the X axis perpendicular to the axis On the card-holder carriage (1), a magnetic card (4) positioned and held in position by known rusting means as described in patent FR 1,591. cited above. The displacement of the card-holding carriage (1) is as a motor (5) of the stepping type via a coupling (6) produced by a flat belt notched in polyurethane reinforced with steel wires.
Le couplage moteur/chariot peut bien entendu ê réalisé de diverses façons, par exemple par bande en acier, fil, par crémaillère ou par vis sans fin/écrou.Motor / carriage coupling can of course be carried out in various ways, for example by steel strip, wire, by rack or by worm / nut.
Le déplacement de la tête magnétique (3) est effec parallèlement à l'axe des pistes magnétiques par le moteur du système de guidage. Ce dernier comprend également des ra e guidage (8) d'un chariot porte-tête (9) s'étendant entre supports (10) des rails, une courroie (11) d'entrainement chariot porte-tête entre un galet de retour (12) et un ga écarteur (13) couplée au moteur (7). L'alternance du mouvem de droite à gauche est réalisée de manière connue par pincem de l'un ou de l'autre brin de la courroie comme dans le bre FR 1.591.591 précité.The movement of the magnetic head (3) is effected parallel to the axis of the magnetic tracks by the motor of the guidance system. The latter also comprises ra e guide (8) of a head carriage (9) extending between supports (10) rails, a belt (11) driving head carriage between a return roller ( 12) and a spacer (13) coupled to the motor (7). The alternation of the movement from right to left is carried out in a known manner by pincem of one or the other strand of the belt as in bre FR 1.591.591 cited above.
De préférence le moteur (7) est un moteur autorég pour entraînement direct à deux vitesses 60 trs/min. 180 trs/min. De même, le moteur (5) comporte trois vitesses po un déplacement du chariot porte-carte. Ces différentes vitess sont utilisées de la manière suivante selon le mode de trait ment sélectionné: - une première vitesse de chaque moteur en mode lecture ou en mode enregistrement;Preferably, the motor (7) is a self-regulating motor for direct drive at two speeds 60 rpm. 180 rpm. Likewise, the motor (5) has three speeds for a movement of the card holder carriage. These different speeds are used in the following manner depending on the processing mode selected: - a first speed of each motor in reading or recording mode;
- une deuxième vitesse plus rapide que la première en mo effacement (et en mode déplacement simple pour ladite tê magnétique) ; - une troisième vitesse en mode déplacement simple.- a second speed faster than the first in erasing mode (and in simple movement mode for said magnetic head); - a third gear in single displacement mode.
Les moyens de déplacement ainsi réalisés permette notamment pour le chariot porte-carte, ' sur comman d'actionnement du moteur (5) , un déplacement en avant ou arrière par pas d'environ 3,25 mm correspondant à la distan entre deux pistes consécutives. Un adressage de la positi dudit chariot par rapport à la tête magnétique suivant l' quelconque des deux sens opposés de son axe de déplacement e rendu possible par une commande répétée ou maintenue 1'actionnement du moteur . Comme on peut le voir sur la figure 2, la tête magn tique (3) portée sur le chariot porte-tête peut se déplacer s les rails de guidage (8) rectilignes entre deux positio extrêmes A et B correspondant aux extrémités des pistes magn tiques. Des détecteurs de position (14) et (15) coopèrent av le système de guidage (2) de manière connue, telle que décri dans le brevet FR 1.591.591 précité, pour provoquer en fin piste magnétique soit le retour, soit l'arrêt du chariot port carte (1) du système de guidage (2).The displacement means thus produced allows in particular for the card-holding carriage, ' on the engine actuation control (5), a displacement in front or rear in steps of approximately 3.25 mm corresponding to the distance between two consecutive tracks . Addressing of the position of said carriage with respect to the magnetic head in any of the two opposite directions of its axis of movement made possible by a repeated command or maintained actuation of the motor. As can be seen in Figure 2, the magnetic head (3) carried on the head carriage can move s the straight guide rails (8) between two extreme positions A and B corresponding to the ends of the magnetic tracks . Position detectors (14) and (15) cooperate with the guidance system (2) in a known manner, as described in the aforementioned patent FR 1,591,591, in order to cause the magnetic track to either return or stop. of the card holder carriage (1) of the guidance system (2).
Selon l'invention, on voit que le système de guida (2) de la tête magnétique s'étend au delà de la surface ladite carte de manière suffisante pour permettre le 'dégageme latéral (indiqué en pointillé) de la tête hors de la surface la carte magnétique. Ainsi, pendant les manoeuvr d'introduction et d'éjection de la carte magnétique, la tê magnétique peut être dégagée dans cette troisième position afin de ne pas gêner mécaniquement le déplacement de la cart Pour des raisons d'encombrement, le dégagement latér s'effectue de préférence du côté du moteur (7) du système guidage, le chariot porte-tête venant en butée contre l'un supports (10) des rails de guidage.According to the invention, it is seen that the guided system (2) of the magnetic head extends beyond the surface of said card sufficiently to allow the lateral dégageme (shown dotted) of the head above the surface the magnetic card. Thus, during the maneuvers of introduction and ejection of the magnetic card, the magnetic head can be released in this third position so as not to hinder mechanically the movement of the cart. For reasons of space, the lateral release is preferably performs on the motor side (7) of the system guide, the head carriage comes into abutment against one of the supports (10) of the guide rails.
Bien entendu, ce dégagement latéral peut être prév l'une ou/et à l'autre des deux extrémités du système de g dage. Dans la réalisation de la figure 2, l'un au moins détecteurs de position, celui (15) du côté du dégagem latéral, est un détecteur de passage: celui-ci peut être type mécanique, optique, ou magnétique. Il a été retenu préférence des capteurs optiques ayant une précision d'envi 0,1 mm.Of course, this lateral clearance can be prevented at one or / and at the other of the two ends of the gaging system. In the embodiment of FIG. 2, at least one position detector, that (15) on the side of the lateral clearance, is a passage detector: this can be mechanical, optical, or magnetic. Optical sensors with an accuracy of approximately 0.1 mm have been chosen.
Selon une caractéristique de l'invention ledit dét teur de position (15) coopère avec le système de guidage de tête magnétique pour assurer un dégagement du chariot por tête au delà de la zone de déplacement de la carte magnéti pendant les manoeuvres de l'introduction et de l'éjection cette dernière.According to a characteristic of the invention, said position detector (15) cooperates with the magnetic head guide system to ensure that the carriage for head is cleared beyond the zone of movement of the magnet card during the maneuvers of the introduction. and ejecting the latter.
Comme on peut le voir sur la figure 3, cette tr sième position C peut être mise à profit pour la réalisat d'un verrouillage du déplacement du chariot porte-tête lors le magnétophone est hors tension, afin de pouvoir le dépla dans de meilleures conditions, sans risque de détérioration la tête magnétique. En effet, le chariot porte-tête vient butée à droite contre un des supports (10) du rail de guid et à gauche contre une portion (16) du chariot porte-ca faisant saillie devant le chariot porte-tête. Ainsi, le chari porte-carte présente une position particulière, dans laque il coopère avec le système de guidage (2) pour assurer le ve rouillage du déplacement du chariot porte-tête.As can be seen in Figure 3, this third position C can be used to achieve a locking movement of the head carriage when the tape recorder is turned off, in order to be able to move it in better conditions , without risk of damage to the magnetic head. Indeed, the head carriage comes to a stop on the right against one of the supports (10) of the guide rail and on the left against a portion (16) of the carriage carrying that protrudes in front of the head carriage. Thus, the card holder carrier has a particular position, in which it cooperates with the guide system (2) to ensure the rusting of the movement of the head carrier carriage.
A la figure 4, on voit que le chariot porte-tête ( est doté à sa partie inférieure d'une languette (17) s'étenda sensiblement sur toute la largeur du chariot porte-tête et do le plan est parallèle à l'axe de guidage. Ladite languette (1 coopère avec un détecteur optique (15) en forme de fourche interrompant le faisceau optique allant d'une branche fourche à l'autre pour donner une information de la position chariot porte-tête (9). Il comporte également à sa partie sup rieure une partie (16) faisant saillie sur le dessus destinée à coopérer avec le chariot porte-carte pour led verrouillage.In Figure 4, we see that the head carriage (has at its lower part a tongue (17) extends substantially over the entire width of the head carriage and do the plane is parallel to the axis Said tongue (1 cooperates with an optical sensor (15) in the form of a fork interrupting the optical beam going from one fork branch to the other to give information on the position of the head carriage carriage (9). also at its upper part a part (16) projecting from the top intended to cooperate with the card holder carriage for locking led.
A la figure 5, on voit que le magnétophone (19) l'invention comporte un clavier (20) groupant toutes les co mandes, relié à des éléments électromécaniques ou électroniqu de commande des déplacements des chariots porte-carte et port tête du magnétophone du type connu. En mode direct, ce clavi permet d'utiliser rationnellement le magnétophone d'une seu main contrairement à la technique antérieure, notamment en qui concerne l'adressage de la tête magnétique dans l'un que conque des deux sens possibles de son déplacement par u pression continue ou répétée sur la touche correspondante.In FIG. 5, it can be seen that the tape recorder (19) the invention comprises a keyboard (20) grouping all the controls, connected to electromechanical or electronic elements for controlling the movements of the card-carrying carriages and head port of the tape recorder of known type. In direct mode, this keyboard makes it possible to rationally use the tape recorder with just one hand, unlike the prior art, in particular as regards the addressing of the magnetic head in one conch of the two possible directions of its displacement by u continuous or repeated pressing of the corresponding key.
Pour rationaliser encore plus l'utilisation du magn tophone, étendre son domaine d'application et simplifier fabrication sur le plan mécanique, le magnétophone comporte microprocesseur (non représenté), relié de manière connu d'une part aux éléments électro-mécaniques ou électroniques commande des déplacements des chariots du magnétophone, d'autre part au clavier.
