Stenographic machine including a disposable ribbon cartridge
摘要:
A compact and disposable stenographic ribbon cartridge system includes a cartridge driven by an external drive. The cartridge contains a densely-packed ribbon that is automatically inked. Under urging of the drive, the ribbon travels through an external guide that holds the ribbon between the character trunnion and the paper platen. A sealed ink reservoir is disposed above the ribbon chamber. The ribbon is pulled by an idler gear and a drive gear. The idler gear is in contact with a wick extending from the reservoir. As the idler gear rotates, it wicks the ink onto itself and transfers the ink to the ribbon as it makes contact. The external drive system is coupled to the platen so as to cause movement of the ribbon upon movement of the platen.
