PURPOSE:To effectively utilize a CRT and a printer in addition to a CPU of a teletext reception section by providing a bus connector to the teletext section so as to connect the connector to a word processor and a home bus terminal equipment or the like. CONSTITUTION:The CPU 10 of the teletext reception section 1 is connected to a CAPTAIN terminal equipment 27, a work processor 28, a floppy disk 29 and a home bus terminal equipment 30 via a bus connector 21 and bus lines 11, 20. In operating the reception section as the terminal equipment 27, a program ROM 31 is connected to the CPU 10 via the connector 21 or the like, and in operating it as the terminal equipment 30, after a prescribed logic matching is applied between a home bus 46 and the reception section 1, the equipment 30 is connected to the CPU 10. In operating the reception section 1 as the processor 28, the word processor 28 is connected to the CPU 10 via a microcomputer 38 and the program ROM 37 and the display and print of character/graph are applied by using the CRTC 8 and the printer 26. Thus, the CRT and the printer 26 or the like are effectively used in addition to the CPU 10.
