ABSTRACT:
A stenotype machine has a casing with a rear panel and a front panel. The casing is substantially symmetrical with respect to a plane bisecting and perpendicular to the rear and front panels. The casing further has a top panel intersecting the front panel at an upper edge thereof and of maximum width at its intersection with the front panel. The machine further includes a keyboard with keys on first, second, third and fourth additional panels which have keys to be operated by the user's right thumb, right fingers, left thumb and left fingers. The second and fourth additional panels intersect vertical side edges of the front panel and make an angle of 60.degree.-70.degree. with each other. The first and third additional panels intersect the second and fourth additional panels, respectively. The second additional panel intersects the first additional panel at right angles thereto and the fourth additional panel intersects the third additional panel at right angles thereto. The machine can be worn, whereby the user can walk around while using the machine. Some of the keys have surfaces with modified texture to serve as a non-visual warning if the user's hand has drifted, whereby the user can make necessary hand readjustment without looking at the keyboard. Certain adjacent pairs of keys are modified to provide spaces therebetween of increased width in the direction facing the user.
