Abstract

PURPOSE: To make it possible to perform the control dependent upon a micro processor easily even in case of high-speed data transfer by providing a temporary storage circuit of data, a latch circuit for discrimination of the kind of data, and an arrival order latch circuit of various data.
CONSTITUTION: Type selection and hammering, carriage movement and form feeding are indicated by print strobe 36, carriage strobe 37 and form feeding strobe 38 respectively. Strobes 36, 37 and 38 are transferred from an external controller according to request signal 34, and their data are stored in determined areas in temporary storage circuit 15. Latch circuit 16 inhibits the external controller from issuing a data request and reports the fact of data transfer to a micro processor. Set contents of circuit 16 at a strobe receiving time are stored in an area of order latch circuit 17. Under a state where all past data transfer contents are stored, the circuit waits the firmware processing of data transfer of the micro processor.
