Abstract

Le dispositif d'introduction comprend un magasin (6) avec une paroi antérieure (9) présentant un plan incliné (45) muni d'éléments de retenue pour la pile de feuilles contenue dans le magasin sous forme de bandes de velours (48) dont les fibrilles retiennent les feuilles par leur bord antérieur. Un arbre d'entraínement (23) porte des galets d'entraínement (20) comportant un secteur à coefficient de friction élevé (100) pour entraíner la feuille la plus élevée de la pile et un secteur (101) à coefficient de friction faible permettant le glissement de la feuille lors d'une phase d'alignement. L'arbre d'entraínement (23) est mis en action par un mécanisme d'entraínement (50) comportant un embrayage avec un pignon échancré (62) à deux échancrures définissant des positions de repos et d'arrêt d'alignement coopérant avec un levier d'embrayage et de retenue (66) commandé par rotation inverse du moteur d'entraínement (58) de l'imprimante. Un dispositif d'avancement (54) permet d'effectuer l'engrènement du pignon échancré (62) avec un pignon intermédiaire (61) suite à une commande d'embrayage. Des cames d'actionnement (106) permettent de repousser la plaque de support (12) des feuilles dans la position de repos. Cette plaque de support (12) est subdivisée en trois parties élastiquement sollicitées par trois ressorts (16) en direction des galets d'entraínement (20).
Cette construction du dispositif d'introduction permet un fonctionnement fiable et simple, un nombre de composants réduit et un faible prix de revient.

Figure 00000001
The introducer comprises a magazine (6) with a front wall (9) having an inclined plane (45) provided with retaining elements for the stack of sheets contained in the magazine in the form of velvet strips (48) of which the fibrils retain the leaves by their anterior edge. A drive shaft (23) carries drive rollers (20) having a sector with high coefficient of friction (100) to drive the highest sheet of the stack and a sector (101) with low coefficient of friction allowing sliding of the sheet during an alignment phase. The drive shaft (23) is actuated by a drive mechanism (50) comprising a clutch with a notched pinion (62) with two notches defining rest and alignment stop positions cooperating with a clutch and retainer lever (66) controlled by reverse rotation of the printer drive motor (58). A advancement device (54) makes it possible to engage the notched pinion (62) with an intermediate pinion (61) following a clutch command. Actuation cams (106) are used to push the support plate (12) of the sheets back into the rest position. This support plate (12) is subdivided into three parts resiliently stressed by three springs (16) in the direction of the drive rollers (20).
This construction of the introduction device allows reliable and simple operation, a reduced number of components and a low cost price.
