PURPOSE:To increase the operability, by providing a key selecting items and also providing a key which fixes the key state or makes effective only when it is pushed, when a plurality of items are assigned to the keys. CONSTITUTION:When three items correspond to one key, selection keys 5, 6, 7 to select the items are prepared. When an item key 4 is inputted while depressing the selection key 5, the item ''Persimmon'' is inputted. A lock key 8 is wed to fix the selection key to a certain state. When the selection key 6 is depressed after the lock key 8 is depressed, the state of selected item with the selection key 6, continues after a hand is detached from the selection key.
