ABSTRACT:
To provide a gear unit apparatus for a printer in which the assembling characteristics and maintenance workability of driving sections for transferring a printing paper to be printed can be improved, and particularly assembling, replacement and maintenance work can be easily performed on a platen roller and a transfer roller. The present invention focuses on unitizing a group of belts and a group of gears independently of a printer main body, and is configured such that a unit bracket that is detachable to a printer bracket is provided independently of the printer bracket, a drive motor, the belt group and the gear group are assembled to the unit bracket, and, when the unit bracket is attached to the printer bracket, a platen roller gear of a platen roller and a transfer roller gear of a transfer roller can be engaged with each other.
