Abstract

An interchangeable metallic cushion bearing (10) is adjusted and fixed on the slide (5) adjusts for excessive play due to wear. The bearing is designed for use in a Sony Playstation. The computer games laser disk rotates around a support (6). Disk reading is done through a lens (1) on a carriage (3). Disk sweep is along (A,B) by translation movement of the carriage. Carriage movement is done by a motorized rack and pinion system (7,4,9). Positioning of the carriage with respect to the read axis is ensured by a slide system (5). Play increases due parts rubbing together, this causes, during speed change or inversion, discontinuity in laser disk reading causing maloperation of the console. .

Le présent dépôt de brevet a été motivé par des défaillances systématiques de fonctionnement de la console de jeux, (marque déposée"Playstation"de chez SONY et apporte une solution validée sur prototype.  The present patent filing was motivated by systematic failures in the operation of the game console (registered trademark "Playstation" from SONY and provides a solution validated on prototype.

Présentation du problème.  Presentation of the problem.

En référence à la figure 1, le bloc lentille est représenté avec les différents composants : (1) lentille laser, (2) bâti, (3) chariot, (4) engrenage, (5) glissière revêtue d'une feuille métallique, (6) support disque laser, (7) moteur, (8) cordon d'alimentation, (9) crémaillère.  With reference to FIG. 1, the lens block is represented with the various components: (1) laser lens, (2) frame, (3) carriage, (4) gear, (5) slide coated with a metal sheet, ( 6) laser disc support, (7) motor, (8) power cord, (9) rack.

La figure 2, représente un croquis situant la partie métallique rapportée (10) FIG 2.  FIG. 2 represents a sketch locating the added metal part (10) FIG 2.

Analyse de fonctionnement.  Functional analysis.

Le disque laser est entraîné en rotation autour du support (6). The laser disc is rotated around the support (6).

Sa lecture est assurée par la lentille (1) du chariot (3).

Its reading is ensured by the lens (1) of the carriage (3).
Figure img00010001

Le balayage du disque s'effectue suivant (A. B) par translation du chariot (3). The disk is scanned as follows (A. B) by translation of the carriage (3).

La mise en mouvement du chariot est assurée par un système pignoncrémaillère motorisé (7,4, 9). The carriage is set in motion by a motorized rack and pinion system (7,4, 9).

La mise en position du chariot par rapport à l'axe de lecture est assurée par un système de glissière (5). The positioning of the carriage relative to the reading axis is ensured by a slide system (5).

En effet, le jeu de fonctionnement augmente dans le temps, dû à l'usure des parties soumises au frottement. Un rotulage se produit alors à chaque changement de vitesse ou inversion de sens, provoquant une discontinuité de lecture du disque laser, entraînant le dysfonctionnement de la console, les jeux sont rattrapés par gravité.  In fact, the operating clearance increases over time, due to the wear of the parts subjected to friction. A swiveling then occurs with each change of speed or reversal of direction, causing a discontinuity of reading of the laser disc, causing the dysfunction of the console, the games are caught up by gravity.

La présente invention perfectionne le système du guidage du chariot porte lentille laser, et assure un bon fonctionnement de la console. Sur le prototype (FIG. 2), il a été monté un coussinet métallique (10) interchangeable sur la glissière (5), ce qui présente le double avantage de réparer les problèmes existants tout en pouvant s'adapter à la fabrication actuelle sans grande modification et à faible coût. The present invention improves the system for guiding the laser lens carriage, and ensures proper operation of the console. On the prototype (FIG. 2), a interchangeable metal pad (10) has been mounted on the slide (5), which has the double advantage of repairing existing problems while being able to adapt to current manufacturing without much modification and low cost.
