Abstract

The cassette (1) of general parallelepipedal, substantially cubic shape contains a typeholder bowl (3) and carries two spools (8) for the inking ribbon (9). The active side of the ribbon between the two spools is "straightened" by a straightening device which causes it to pass from a position, in which it is arranged in a plane substantially perpendicular to the axis (7) of the typeholder bowl, into a plane in which it is arranged substantially parallel to this axis and opposite the typing point, in order to return to a plane perpendicular to this axis, from which it winds onto the take-up spool. Thus, one and the same cassette (1) is common to the typeholder (3) and to the inking ribbon (9), thereby increasing the convenience of use of the machine. <IMAGE>

L'accessoire représenté comprend une cassette 1, de forme générale parallélépipédique, sensiblement cu­bique, en matière plastique. Cette cassette est munie d'un couvercle 2, de forme correspondante, également en matière plastique, représenté à la fig. 1 séparé de la cassette, mais qui s'emboîte sur celle-ci, comme le montre la fig. 3.The accessory shown comprises a cassette 1, of generally rectangular, substantially cubic shape, made of plastic. This cassette is provided with a cover 2, of corresponding shape, also made of plastic, shown in FIG. 1 separate from the cassette, but which fits on it, as shown in fig. 3.

La cassette 1 est destinée à contenir un sup­port de caractères rotatif, en forme dite de "tulipe", dé­signé d'une façon générale par 3, qui comprend un corps constitué par un disque 3a percé d'un trou central 4 destiné à recevoir un arbre de la machine, non représen­té. La tulipe porte-caractères comprend des bras élasti­ques 3b, sensiblement perpendiculaires au plan du corps 3a, et qui prennent naissance à la périphérie de ce der­nier. Ces bras élastiques 3b sont munis, à leur extrémi­té, de caractères 3c.Cassette 1 is intended to contain a rotating character support, in the form of a "tulip" shape, generally designated by 3, which comprises a body 3 constituted by a disk pierced with a central hole 4 for receiving a shaft of the machine, not shown. The character-carrying tulip comprises elastic arms 3 b , substantially perpendicular to the plane of the body 3 a , and which arise at the periphery of the latter. These elastic arms 3 b are provided, at their end, with characters 3 c .

Le corps central 3a de la tulipe porte-carac­tères présente un collet 3d engagé sur un manchon 1a que présente le fond, désigné par 1b, de la cassette. Le cou­vercle 2 de cette dernière présente une partie rentrante dont la paroi latérale 2a est tronconique, mais qui pour­rait également être cylindrique, qui s'engage à l'inté­rieur de la couronne formée par l'ensemble des bras élas­tiques 3b de la tulipe porte-caractères. Le fond, dési­gné par 2b, de cette partie rentrante est découpé de fa­çon à former un ressort à boudin 2c qui prend appui sur le corps central 3a de la tulipe porte-caractères pour maintenir celle-ci appliquée contre le manchon 1a de la cassette 1. Lorsque cette dernière est en place dans la machine à écrire, celle-ci est agencée de façon à agir axialement sur la tulipe porte-caractères pour la séparer du bord supérieur du manchon 1a et la libérer ainsi, ce qui lui permet d'être entraînée librement par la machine.The central body 3 a of the character-carrying tulip has a collar 3 d engaged on a sleeve 1 a which has the bottom, designated by 1 b , of the cassette. The cover 2 of the latter has a re-entrant part whose side wall 2 a is frustoconical, but which could also be cylindrical, which engages inside the crown formed by the set of elastic arms 3 b of the tulip character holder. The bottom, designated by 2 b , of this re-entrant part is cut so as to form a coil spring 2 c which rests on the central body 3 a of the character-carrying tulip to keep it applied against the sleeve 1 a of the cassette 1. When the latter is in place in the typewriter, the latter is arranged so as to act axially on the character tulip to separate it from the upper edge of the sleeve 1 a and thus release it, which allows it to be driven freely by the machine.

La cassette 1 porte non seulement le support de caractères, mais également un ruban encreur permettant l'impression. A cet effet, ses deux côtés latéraux opposés, désignés par 1c, présentent chacun une saillie 1d formant tourillon. Les deux tourillons sont coaxiaux, leur axe commun, désigné par 6 à la fig. 3, étant perpendiculaire à l'axe, désigné par 7, de la tulipe porte-caractères. Ces tourillons portent chacun une bobine 8 sur laquelle est enroulé le ruban encreur, désigné par 9. Ces bobines tour­nent toutes les deux dans le même sens, indiqué par des flèches 10 à la fig. 4, la bobine de droite étant débitri­ce et celle de gauche étant réceptrice.Cassette 1 carries not only the character support, but also an ink ribbon for printing. For this purpose, its two opposite lateral sides, designated by 1 c , each have a projection 1 d forming a pin. The two pins are coaxial, their common axis, designated by 6 in FIG. 3, being perpendicular to the axis, designated by 7, of the character-carrying tulip. These pins each carry a coil 8 on which is wound the ink ribbon, designated by 9. These coils both rotate in the same direction, indicated by arrows 10 in FIG. 4, the right reel being supplying and that of the left being receiving.

L'entraînement de ces bobines est assuré par un cordonnet sans fin 11 guidé par des galets 12 (fig. 4). Ce cordonnet 11 entoure les deux enroulements de ruban sur les deux bobines 8, sur la plus grande partie de la péri­phérie desdits enroulements, et effectue un tour mort au­ tour d'un galet d'entraînement 13 entraîné lui-même par la machine. Il résulte de cet agencement que le déplace­ment linéaire du ruban est à vitesse constante, quel que soit son degré de déroulement de la bobine débitrice et son degré d'enroulement sur la bobine réceptrice.The drive of these coils is ensured by an endless cord 11 guided by rollers 12 (fig. 4). This cord 11 surrounds the two windings of ribbon on the two coils 8, over most of the periphery of said windings, and performs a dead turn at turn of a drive roller 13 itself driven by the machine. It follows from this arrangement that the linear displacement of the ribbon is at constant speed, whatever its degree of unwinding of the supply reel and its degree of winding on the take-up reel.

L'axe des bobines étant perpendiculaire à l'axe du support de caractères, pour des raisons d'en­combrement, il est nécessaire de pouvoir redresser la partie "active" du ruban située en regard du point de frappe, afin de la rendre sensiblement parallèle à l'axe 7 de la tulipe porte-caractères.The axis of the reels being perpendicular to the axis of the character support, for reasons of space, it is necessary to be able to straighten the "active" part of the ribbon located opposite the striking point, in order to make it substantially parallel to axis 7 of the character tulip.

A cet effet, la cassette porte un organe re­dresseur, désigné d'une façon générale par 14 (fig. 4), en forme d'étrier, dont les branches, désignées par 14a, sont percées chacune d'un trou servant à son articu­lation sur des gouttes intérieures 1e que présentent les parois latérales 1c de la cassette, et qui sont coaxiales aux tourillons 1d portant les bobines 8.For this purpose, the cassette carries a rectifier member, generally designated by 14 (fig. 4), in the shape of a stirrup, the branches of which, designated by 14 a , are each pierced with a hole serving for its articulation on internal drops 1 e which have the side walls 1 c of the cassette, and which are coaxial with the pins 1 d carrying the coils 8.

La partie transversale, désignée par 14b, du redresseur en forme d'étrier 14 porte deux éléments de redressage 15 présentant chacun une piste formée d'un premier tronçon, désigné par 15a, situé dans un plan perpendiculaire à l'axe 7 du support de caractères, un second tronçon, désigné par 15b, incliné par rapport au tronçon 15a, et un troisième tronçon, désigné par 15c, situé dans un plan parallèle à l'axe 7.The transverse part, designated by 14 b , of the stirrup-shaped rectifier 14 carries two straightening elements 15 each having a track formed by a first section, designated by 15 a , located in a plane perpendicular to the axis 7 of the character support, a second section, designated by 15 b , inclined with respect to section 15 a , and a third section, designated by 15 c , located in a plane parallel to axis 7.

Grâce à la tension à laquelle est soumise la partie du ruban située entre les deux enroulements, formant le brin désigné par 9a, lorsque la machine est en service, le ruban, à son déroulement de la bobine débitrice, s'engage sur la partie 15a de l'élément de redressage de droite (fig. 4) puis, en suivant la par­tie 15b, se redresse pour s'appliquer contre la partie 15c. A sa sortie, il effectue le mouvement inverse, appliqué tout d'abord contre la partie 15c de l'élément redresseur de gauche, puis passant progressivement sur la partie 15b pour enfin quitter le redresseur sur la partie 15a et s'enrouler sur la bobine réceptrice. Ainsi, la zone médiane du brin 9a du ruban, située en regard du point de frappe, se trouve dans un plan sensiblement parallèle à l'axe 7 du support de carac­tères, ce qui permet la frappe, à l'aide d'un organe de frappe non représenté car appartenant à la machine imprimante, situé à l'intérieur de la couronne formée par l'ensemble des bras élastiques 3b de la tulipe porte-caractères 3. Cela permet la frappe sur un sup­port d'écriture (feuille de papier) passant sur le cy­lindre de la machine représenté schématiquement en traits mixtes aux figs. 2 et 5 où il est désigné par 16.Thanks to the tension to which the part of the ribbon situated between the two windings is subjected, forming the strand designated by 9 a , when the machine is in service, the ribbon, as it unwinds from the supply reel, engages on the part 15 a of the straightening element on the right (fig. 4) then, following part 15 b , straightens up to apply against part 15 c . At its exit, it performs the reverse movement, applied first against part 15 c of the left rectifier element, then progressively passing over part 15 b to finally leave the rectifier on the part 15 a and wind up on the take-up reel. Thus, the central region of the strand ribbon 9 has, next to the point of typing, is in a plane substantially parallel to the axis 7 of the character carrier, which allows minting, with a member not shown impactor as belonging to the printing machine, located inside the ring formed by the set of resilient arms 3 b of the tulip type carrier 3. This allows strikes on a writing medium (sheet of paper) passing over the machine cylinder shown schematically in phantom in Figs. 2 and 5 where it is designated by 16.

Il est à remarquer que le brin 9a du ruban est incliné par rapport à la direction d'écriture, comme le montre la fig. 1, ce qui permet une meilleure utilisation du ruban, son pas, c'est-à-dire la distance dont il avance entre chaque frappe, pouvant être plus court que si le brin 9a était parallèle à la direction d'écriture, c'est-à-dire à l'axe du cylindre 16 de la machine.It should be noted that the strand 9 a of the tape is inclined with respect to the write direction as shown in Fig. 1, which allows better use of the ribbon, its pitch, that is to say the distance by which it advances between each keystroke, which can be shorter than if the strand 9 a was parallel to the writing direction, c that is to say to the axis of the cylinder 16 of the machine.

Grâce au fait que l'organe redresseur 14 est articulé sur la cassette 1, il est apte à se dé­placer en un mouvement basculant, commandé à l'aide d'un actuateur, non représenté, pour occuper deux positions, l'une de travail, dans laquelle il pré­sente le ruban en regard du point de frappe et l'au­tre, éclipsée, dans laquelle il dégage le point de frappe, rendant ainsi visible l'écriture à l'opéra­teur. La masse du redresseur 14 étant faible, il n'a qu'une faible inertie, ce qui est un avantage pour ce qui est de ses déplacements oscillants qui doivent pouvoir se faire à grande vitesse.Thanks to the fact that the rectifier member 14 is articulated on the cassette 1, it is able to move in a rocking movement, controlled using an actuator, not shown, to occupy two positions, one of work , in which it presents the ribbon opposite the striking point and the other, eclipsed, in which it releases the striking point, thus making the writing visible to the operator. The mass of the rectifier 14 is low, it has only a low inertia, which is an advantage with regard to its oscillating movements which must be able to be done at high speed.

Dans la variante de la fig. 5, l'organe redresseur, désigné par 17, n'est pas oscillant, comme dans la première forme d'exécution, mais coulissant. L'actuateur, non représenté, agit sur un poussoir 17a que présente le redresseur pour le soulever et l'amener ainsi dans sa position de tra­vail dans laquelle il présente le ruban en regard du point de frappe.In the variant of FIG. 5, the rectifier member, designated by 17, is not oscillating, as in the first embodiment, but sliding. The actuator, not shown, acts on a pusher 17 a which the rectifier presents in order to lift it and thus bring it into its working position in which it presents the ribbon opposite the striking point.

La présente disposition (l'utilisation d'une cassette commune au support de caractères et au ruban encreur) conduit à des avantages divers :This provision (the use of a cassette common to the character support and the ink ribbon) leads to various advantages:

L'opérateur change simultanément ruban et support de caractères sans aucune difficulté. La cassette étant jetable, il n'est pas tenté d'utiliser des supports de caractères présentant une usure exagérée : lorsque le ruban est terminé, la tulipe porte-caractères est sacri­fiée. La réalisation de telles tulipes, en matière plas­tique, permettant des prix de revient extrêmement bas, son sacrifice est sans incidence sur le coût d'exploita­tion de la machine à écrire.The operator changes ribbon and character support simultaneously without any difficulty. The cassette being disposable, it is not tempted to use supports characters with excessive wear: when the ribbon is finished, the character tulip is sacrificed. The realization of such tulips, in plastic, allowing extremely low cost prices, its sacrifice has no impact on the operating cost of the typewriter.

De plus, les dimensions de la cassette qui, sans être exagérées,ne peuvent pas être réduites au-delà d'un certain minimum, permettent d'augmenter la dimension du support de caractères et, par conséquent, d'augmenter le nombre des caractères portés par celui-ci. Cela a pour conséquence indirecte que l'on peut, sur un même support de caractères, en l'occurrence une tulipe, prévoir tous les caractères d'une même écriture ou plus précisément d'un même type d'écriture nécessaires pour permettre la réalisation de cette même écriture à des pas différents. En effet, lorsqu'une écriture est utilisée à des pas dif­férents, certains caractères sont identiques pour tous les pas alors que d'autres sont différents d'un pas à l'autre, afin que l'esthétique de l'écriture soit sauvegardée. Dès lors, un seul et même support de caractères permettra de réaliser l'écriture à des pas différents, selon les besoins, ce qui est particulièrement utile avec des machines impri­mantes à pas sélectionnable.In addition, the dimensions of the cassette which, without being exaggerated, cannot be reduced beyond a certain minimum, make it possible to increase the size of the character support and, consequently, to increase the number of characters. worn by it. This has the indirect consequence that one can, on the same support of characters, in this case a tulip, predict all the characters of the same writing or more precisely of the same type of writing necessary to allow the realization of this same writing at different steps. Indeed, when a writing is used at different steps, certain characters are identical for all the steps while others are different from one step to another, so that the aesthetics of the writing is saved. Therefore, a single character support will allow writing at different steps, as needed, which is particularly useful with printing machines with selectable steps.

Il est à remarquer que l'invention n'est pas limitée à la forme d'exécution décrite et représentée :It should be noted that the invention is not limited to the embodiment described and shown:

C'est ainsi que le support de caractères pourra, le cas échéant, ne pas être en forme de tulipe, mais de boule ou de marguerite, par exemple.Thus the support of characters may, if necessary, not be in the shape of a tulip, but of a ball or a daisy, for example.

On pourra également disposer le support de ca­ractères et les bobines du ruban dans des positions rela­tives différentes de ce qui a été décrit et représenté dans le cas d'espèce.It will also be possible to have the character support and the reels of the ribbon in relative positions different from what has been described and shown in the present case.

L'entraînement du ruban pourra être assuré par des moyens différents de ceux du présent exemple.The ribbon can be driven by means different from those of the present example.

On pourra même prévoir que la même cassette porte, outre le ruban encreur et le support de caractères, un ruban correcteur, par exemple.We can even provide that the same cassette carries, in addition to the ink ribbon and the character support, a correction tape, for example.
