PURPOSE:To eliminate errors, by a method wherein data of input means and operation input are compared with the content of an error memory, and normal signal and error signal are outputted thereby normal sound and error sound are informed. CONSTITUTION:Data from input means 32 and operation input are stored in a memory 34 and compared with content of an error memory 38 in an input comparator 36. If the compared signals coincide, error signal 200 is outputted; if both do not coincide, normal signal 100 is outputted. These signals are entered into an input sound information device 40. The normal signal 100 passes through a normal sound generator 42 and the error signal 200 through an error sound generator 44, and then both signals operate a buzzer 46 in respective information sounds. Since error signal is generated, for example, in data input not existing in the keyboard or operation input being different from a prescribed operation procedure, inputs can be checked by means of audio signal information. |
