CONSTITUTION:This equipment is set to the setting mede by depressing a setting mode key 8 of a mode change-over section 7, and digit number information of the limiting information, for example 3, and maximum input setting value of the maximum digit, for example 5, are input into a CPU2 through a key input device 1. Then, by depressing keys of specific divisions of the device 1, divisions of the information previously input are designated, and the previously input limiting information is stored in a desired area of a memory 4. Above mentioned operations are executed on desired divisions, and when settings of all limiting information are completed, the setting mode is released by operating the key 8. Then the registration mode is set for providing against registration processings by depressing a registration key 9. When it is judged that an input which is more than the limiting information set and stored in the memory 4, is made under this registration mode, the operator is informed it by a speaker 11 through an alarming means 10.
