Character-spacing or back-spacing mechanisms; Carriage return or release devices therefor

Introduced: September 1968

Title

Titles differ between systems:

IPC: Character-spacing or back-spacing mechanisms; Carriage-return or release devices therefor

CPC: Character-spacing or back-spacing mechanisms; Carriage return or release devices therefor

Full titles differ between systems:

IPC:

Character- or line-spacing mechanisms > Character-spacing or back-spacing mechanisms; Carriage-return or release devices therefor

CPC:

Character- or line-spacing mechanisms > Character-spacing or back-spacing mechanisms; Carriage return or release devices therefor

IPC and CPC are identically structured here. All 6 subcodes exist in both systems.

2 shared codes have differing titles between IPC and CPC.
