Abstract

L'invention concerne une imprimante opérant par percussion et comportant un marteau perfectionné. Le marteau comprend un solénoïde 56, qui possède un organe magnétique stationnaire 50, traversé par une ouverture 48, et un organe magnétique mobile 54 conçu pour se mouvoir à travers cette ouverture. L'organe magnétique mobile 54 est accéléré par un flux 57 provenant de l'organe magnétique stationnaire et qui passe à travers l'organe magnétique mobile alors que l'entrefer 52 entre les organes magnétiques stationnaire et mobile se ferme de telle façon que l'organe magnétique mobile soit sensiblement en projection libre avant que la surface de percussion 58 raccordée à l'organe magnétique mobile ne frappe un des caractères 28. Imprimante opérant par percussion et comportant un marteau perfectionne.A percussion printer including an improved hammer is disclosed. The hammer comprises a solenoid 56, which has a stationary magnetic member 50, through which an opening 48 passes, and a movable magnetic member 54 designed to move through this opening. The movable magnetic member 54 is accelerated by a flux 57 coming from the stationary magnetic member and which passes through the movable magnetic member while the air gap 52 between the stationary and movable magnetic members closes so that the movable magnetic member is substantially in free projection before the percussion surface 58 connected to the movable magnetic member strikes one of the characters 28. Printer operating by percussion and comprising an improved hammer.
