DESCRIPTION:
BRIEF SUMMARY
BACKGROUND OF THE INVENTION
This invention relates to an input device capable of inputting characters and symbols by using only numeric keys 0, 1, 2, 3, 4, 5, 6, 7, 8 and 9 of an input keyboard, and further to an apparatus applying said input device for recording characters, and symbols on a film.
Conventionally, it is known that an input device which electronically inputs characters and symbols, can be applied in an electronic apparatus such as a camera, an electronic diary etc. For example, in a camera which has the above-mentioned conventional input device, photographing information such as date, month, year, and some simple characters etc. can be recorded on a film, and besides, some sorts of words are previously memorized in the camera, so the words can be recorded on the film without writing in each of characters. However, in such a conventional manner, some predetermined words are memorized beforehand in the camera, and it is impossible to record arbitrary characters on any portion of a frame of a film, and besides, complicated operations are needed to input even a character.
OBJECTS AND SUMMARY OF THE INVENTION
Accordingly, an object of the present invention is to overcome the drawbacks and limitations of the prior art.
Another object of the present invention is to provide an input device for inputting character and symbol data in an electronic apparatus with a simple operation.
A further object of the present invention is to provide an input device that is mounted to a camera which can easily input arbitrary photographing information and record such information on a frame of film by a loading operation and a bitmap display of the camera.
It is a further object of the present invention to provide an input device in which an address reference table of an information exchange code main memory has a 10 bit row index and a 10 bit column index, where such row index and column index are alternately inputted by using an irreducible minimum number of numeric keys 0, 1, 2, 3, 4, 5, 6, 7, 8 and 9 which are arranged in an input keyboard, where both sets of 10 bit indexes have independent function.
Briefly stated, 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, and 9 in an address reference table of an information exchange code main memory. Ten bits of data corresponding to a column index and ten bits of data corresponding to a row index are alternately inputted through an input keyboard. When a first arbitrary numeral is inputted, a column of characters corresponding to the input numeral is held in an ON state, and is simultaneously displayed on a selected character confirmation display. When a second arbitrary numeral is inputted, a row of characters corresponding to the input numeral is selected, and a single character corresponding to the selected column and row is placed in an ON state, and all other characters are placed in an OFF state. This input device is mounted on a camera, and a bitmap 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. According to an embodiment of the present invention, an input device is applied to a camera having a press plate which is provided with a bitmap display of a line of characters, and pressed onto a film. The bitmap display in which zones for one character are arranged in the line, is basically arranged so as to be exposed in a bitmap display exposure zone on the spool chamber side of one frame of the film. The film is wound up by a film loading operation and an auto-loading mechanism, and photographing information is successively exposed on the frame of the film. Moreover, the bitmap display is provided on the whole press plate of the camera, and pressed onto the film, so the photographing information can be collectively exposed. In order to expose the photographing information on the
