Abstract:
A multi-electron beam source comprising an electron emitting element part including:a plurality of electron emitting elements provided two-dimensionally in a matrix like arrangement on a substrate; opposing terminals of electron emitting elements arranged adjacently in the column direction thereof being electrically connected to each other; terminals on the same side of all the electron emitting elements in the same row being electrically connected; and the plurality of electron emitting elements being arranged in ""m"" rows, ""m"" representing a number of two or more, and a driving circuit part for driving said electron emitting element part,wherein said multi-electron beam source has means for preventing a spike-like voltage from being applied to said electron emitting elements, andwherein said driving circuit part has a driving pulse generating means and a switching means and said means for preventing a spike-like voltage includes means for controlling the ON/OFF operation of said switching means during the period when the output voltage of said driving pulse generating means is lower than the electron emission threshold voltage of said electron emitting elements.
