PURPOSE:To obviate the invisibility of given questions and correct answers on an output device by constituting the above machine in such a manner that the control code stored in a 2nd memory means is updated to the control code stored in a 1st memory means at every change. CONSTITUTION:The global control code stored in the 1st area of the 2nd memory means 12 is updated at every reading out of the 1st memory means 11 by an identification storing means 13 and similarly the local control code stored in the 2nd area of the means 12 is updated at every reading out of the means 11 and the data segments are stored in the 3rd area of the means 12. The data segments stored in the 3rd area are displayed on the output device 15 by a control means 14. The question is presented to the device 15 in the presentation position and state assigned by the control code stored in the 1st and 2nd areas at the time of this display. Since the contents stored in the 1st and 2nd areas are updated to the control code stored in the means 11, the presentation on the device 15 is always updated. The invisibility of the questions and correct answers is, therefore, obviated. |
