PURPOSE:To make the size of a data processor small, by using only one bubble cassette, in loading a program from two external memories to an internal memory. CONSTITUTION:A mounting section 12 is provided with a bubble cassette fitting section and an internal mounting bubble 13, and the fitting section is set with the 1st bubble cassette 10. In a reading control circuit 14 provided at a control section 4', its internal circuit is switched to transmit the data of the 1st bubble cassette 10 to the bubble 13 when the 1st bubble cassette 10 is set to the section 12. In setting the 2nd bubble cassette 11 to the section 12, its internal circuit is switched so that the data in the 2nd bubble cassette 11 can be transmitted to an internal memory 5. The content kept in the internally mounted bubble 13 is constituted so that it can be transmitted to the internal memory 5. |
