<p>An input device by which a character or symbol is retrieved and determined using an irreducible minimum number of numeric keys 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, and 0 in an address reference table of an information exchange code main memory. Ten bits of 0, 1, 2, 3, 4, 5, 6, 7, 8 and 9 of a column and ten bits of 0, 1, 2, 3, 4, 5, 6, 7, 8 and 9 of a row are alternately inputted through an input keyboard. When an arbitrary numeral is inputted, one of arbitrary numeral of column characters of a row on the number side is first inputted preferentially, the numeral is held in an ON state, and it is simultaneously displayed on a selected character confirmation display (48). Next, when another arbitrary numeral is inputted, only the character at intersection of the column and row is definitely in an ON state, and the others are turned off. This input device is mounted on a camera, and a bit map display of a line of characters is provided on a press plate of the camera. Character and symbol data are inputted through the input device, and information is recorded easily and in detail to any portion of one frame of a film.</p> |
