    • PURPOSE:To display the data given from outside on the rear side of a card type electronic calculator, by providing a data input/output part to another calculator and a battery back-up memory in addition to the functions of an ordinary electronic calculator and then operating a mode changeover switch. CONSTITUTION:A display 1, a key group containing the normal tenkey, function keys, etc., a mode changeover switch 2 and table designation keys 3-1-3-4 are provided on the upper side of an electronic calculator. The inside of the calculator includes a data input/output part to another calculator (not shown in the figure) and a memory backed up by a battery. The rear side of the calculator has a display 5. The functions of an ordinary electronic calculator are obtained by setting the switch 2 in a normal mode. When the switch 2 is set in a memory reference mode along with a push of the key 3-1 the table names are displayed out of a memory as shown in the figure. Furthermore a table number is pushed by means of the key 3-2 and tenkey to display the details of the table.
