  • Aegisson and Brenner are the developers of the most widely used phonograph hard and software today. More specifically, two different center elements, a torn arm and a turn table, consist of a cooperative operation achieved in a circular motion. The purpose was achieved in the first place, and the citizenship of today is seen 100 years later. Advances in the use of electronics have further increased the coordination of hardware and software: 3 ⁇ 4wa ?? Now the function of random access is a challenge for the development of phonographs. In the past, hard technicians and soft technicians may have developed from their own standpoint. From the standpoint of phonograph users, what we want is that the most widely used phonographs at present can exhibit random access functions. The first is that the software format represented by the record is the most constructive and interchangeable. Regardless of who plays the record, it can be easily played back on a player who is a general hand-held hardware. No one can disagree that this form of uniformity has caused the rise of the current record, and how important it was later developed.

Abstract

Une cartouche (45) est fixee sur une plaque rotative (34) et une plaque de plastique a l'aide d'ecrous et boulons (41), (41) du corps (6) a une extremite d'un bras de tonalite. La plaque rotative (34) est montee en rotation autour d'un axe de montage rotatif (32) disposee a l'arriere d'un style (30). Une piece de guidage est prevue a l'extremite de la plaque en plastique pour introduire le style de la cartouche (45). Un trou est forme au travers duquel le trou semi-circulaire d'une plaque de selection de chanson (1) preparee en supplement est capable d'etre engage avec la tige centrale d'un plateau tournant et superpose avec le trou central (29) d'une plaque a tige de poussee. Une bande dimorphe (20) est attachee sur chacun des cotes avant et arriere de la plaque (1) pour s'etendre a partir du centre du trou de maniere rectiligne vers la ligne radiale d'un disque. Une butee d'une petite piece de la bande dimorphe pour indiquer le point central du debut de chacune des chansons sur le disque est collee sur la bande (20). La piece de guidage est amenee au contact de la butee pour introduire le style (30) le long du sillon sonore du debut de la chanson desiree sur le disque.
