Abstract

A recording device for recording electrical signals on a moving strip or ribbon-shaped recording medium characterized by the device having a housing, which supports a drive means for rotating a feed roller, a writing needle and means for actuating the writing needle, and a carriage which is received in the housing and supports a supply of the recording medium, and at least one pressure roller. The carriage has a preformed part adjacent to the writing edge which conforms to the desired path for the medium as the carriage is inserted into the housing so that the insertion of the carriage into the housing places the recording medium automatically in the desired path around the writing edge and between the pressure and feed rollers.
