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.
Claims11
In a recording device for recording electrical signals on a moving ribbon-shaped recording medium, said device having a housing, which contains a drive means connected to a feed roller for the recording medium and supports at least one writing needle and means for actuating said needle in response to the electrical signals, said device having a carriage for supporting a supply of the recording medium being releasably inserted into the housing, said carriage providing at least one writing edge for supporting and recording medium as the writing needle writes thereon, said device having a plurality of guide rollers for guiding the recording medium and at least one pressure roller coacting with the feed roller to advance the recording medium, the improvements comprising the housing supporting a first pressure roller adjacent to the end of the writing needle, the carriage supporting a second pressure roller and being provided at one end with a preformed part for supporting the writing edge between the feed roller and the first pressure roller, said preformed part having a configuration that approximates the path of the recording medium as it is passed between the feed and pressure rollers and is engaged by the guide rollers, said carriage supporting at least one guide roller coacting with the writing edge to place the recording medium in the approximate position as the carriage is being inserted into the housing so that after completion of the insertion of the carriage, the recording medium is automatically disposed in the proper path around the writing edge and between the pressure and feed rollers.
In a recording device for recording electrical signals on a moving ribbon-shaped recording medium, said device having a housing, which contains a drive means connected to a feed roller for the recording medium and supports at least one writing needle and means for actuating said needle in response to the electrical signals, said device having a carriage for supporting a supply of the recording medium being releasably inserted into the housing, said carriage providing at least one writing edge for supporting the recording medium as the writing needle writes thereon, said device having a plurality of guide rollers for guiding the recording medium and at least one pressure roller coacting with the feed roller to advance the recording medium, the improvements comprising the housing having one of the pressure rollers mounted adjacent to the end of the writing needle for relative movement in vertically extending slots, the carriage being provided at one end with a preformed part for supporting the writing edge and having a second of the pressure rollers being supported for relative movement in horizontally extending slots, a spring being disposed on the carriage and urging the second pressure roller toward the writing edge, said preformed part having a configuration that approximates the path of the recording medium as it is passed between the feed and pressure rollers and is engaged by the guide rollers, said preformed part forming spreading means for applying pressure during insertion of the carriage in the housing to cause relative movement between the pressure rollers and the feed roller and the movement of each of the pressure rollers in their respective slots, said carriage supporting at least one guide roller coacting with the writing edge to place the recording medium in the approximate position as the carriage is being inserted into the housing so that after completion of the insertion of the carriage, the recording medium is automatically disposed in the proper path around the writing edge and squeezed between the pressure and feed rollers.
