PURPOSE:To prevent erroneous key depressions and facilitate the repair of a trouble, by displaying contents key-inputted from a keyboard on a display. CONSTITUTION:One-card components of key-inputted contents A-H... are stored in order in a buffer 2' and are displayed in order on a display 3. The operator watches displayed contents to check whether they are contents to be punched or not. After the key input for one-card components, contents stored in the buffer 2' are punched on a card in a card punch part 4. The card is read immediately in a card reading part 5 and is sent to a comparator 6. This comparator compares key-inputted contents with contents read in the card reading part 5; and if error is detected, a position signal is sent to flicker a pertinent part on the display 3, and the card is sent to a stacker 7. Thus, an abnormal part due to the trouble of the card punch part 4 is found. |
