PURPOSE:To obtain a diversified memory access function with simple circuit configuration by accessing a picture recording medium and a transmission use reception buffer with a control signal from a common card address generat ing section. CONSTITUTION:A card interface 10 is provided with a switch 104 located between a switch 101 and a memory card 11 and a switch 105 located between a switch 102 and a memory card 11 and with a transmission data reception buffer 20. Output terminals 104A, 105A of the switches 104, 105 are connected to the memory card 11 and output terminals 104B, 105B of the switches 104, 105 are connected to the transmission data reception buffer 20 and the switches 104, 105 are controlled by a transmission control signal from a system control circuit 12. The transmission data reception buffer 20 and the memory card 11 are controlled by an address signal sent through a common bus from a card address generating section 103. |
