Here, since the first control key 9 is in the inspection mode, the input of the comparison pattern using the numeric keys 5 and 8f, as shown in the flow of steps 112, 124, and 115, is performed when the CHKj flag 71 is set. By operating the rCHKj key 5, a comparison operation is performed based on the comparison pattern.

Furthermore, when setting a comparison pattern for only the address "1φφ" in the preset section 55a, the key operations on the keyboard 2 are "1φφJ rXJ rlφφ", "Subtotal J", "cHKJ
And it is sufficient.

Next, a description will be given of an operation for correcting erroneous data in the preset section 55a by checking the erroneous data in the printed out preset section 55a.

For example, "111" to "12F" of the preset section 55a
It has been confirmed that incorrect data has been stored in the address range of rcHKJ rl 1 1j rx"
