• and
• a plurality of switches that are provided for each of the keys to output an electrical signal unique to each of the keys when the keys are pressed;
• a controller that detects the electrical signal output from the key panel and outputs a key code corresponding to the electrical signal, the controller being configured to operate to:
• determine whether the specific key is pressed by detecting the electrical signal;
• and
• output multiple key codes including key codes corresponding to the pair of characters when determined that the specific key is pressed;
• and
• a display unit that displays characters corresponding to the key code output from the controller at a caret position.
