Recording apparatus with exchangeable interface board.

摘要

For enabling variation of specification of a recording apparatus with simple construction, a control board (100) fixedly mounted on the recording apparatus has an engine portion for controlling mechanical operation of the recording apparatus and a control portion for controlling the engine portion. Normally, an interface board (110) is connected to the control board to perform recording operation on the basis of recording signal and so forth from a host system. By installing an optional interface board (111) having a control portion in place of the interface board (110) to control the engine portion of the control board (100), specification of the apparatus can be varied. <IMAGE>
