Abstract
Line printer having a plurality of coaxially arranged rotatable printing rings each bearing a series of characters to selectively effect printing on a paper and a platen movable toward in contact with and away from the printing rings so as to effect printing on the paper interposed between the platen and the printing rings when the platen abuts against the printing rings, each of the printing rings being selectively arrested by a select lever actuated by the printing signal from a control system of the printer thereby positioning desired characters of the respective printing rings in the printing position at which the platen abuts against the printing rings so that a line of printing is produced on the paper simultaneously. The printer comprises a mechanism for additionally printing a mark such as an underline and the like adjacent to particular characters printed on the paper. The mechanism is moved to the printing position by a signal from the control system. The mechanism comprises a printing wire with portions supported by a pair of printing levers swingably arranged at opposite extremities of the coaxially arranged printing rings. The printing wire is supplied with ink from an ink supply each time it is moved out of the printing position.
