Abstract: An electronic musical instrument is designed in a generally guitar-shaped configuration with a fingerboard containing rows of keys replacing each string, one key for each string/fret position. Pressing on a key causes a signal to be provided to a central processing unit which continually scans the fingerboard at a high rate and converts the signals to a plurality of outputs to a synthesizer. Unlike a guitar, a plurality of keys, including a plurality along a single row, may be operated simultaneously to produce a plurality of notes simultaneously. A number of pressure switches and other switches located on the body enable a player to modify the output with vibrato, pitchbend, stereo pan, percussion effects, etc. Additional pressure responsive circuits provide inputs to the central processing unit varying with pressure on the keys. A second embodiment includes a fingerboard with many more rows or columns of keys and more keys per column.

Abstract: A 35 mm-wide photographic film without any perforations typically used to transport this kind of film has one side of its rectangular effective photographic area in a widthwise direction made substantially 30 mm long, thereby widening this effective photographic area, so that the image quality is improved. A photographic camera using that 35 mm photographic film formed without perforations transports the photographic film accurately, and in which the position of the photographic film in its widthwise direction is defined and an image of an object is exposed to the effective photographic area of the photographic film.
