Abstract
Abstract An improved output unit used in recording information on a recording medium is disclosed which comprises a plurality of output parts and in which recording of information is carried out while changing the relative position between the output from the output parts and the recording medium. The improved output unit according to the invention is characterized in that the output parts are arranged in rows in a predetermined direction and are disposed in such a manner that information may be put out selectively from the output parts so as to prevent information from being recorded in overlapping fashion on the recording medium in a manner as often occurs in the conventional unit. Spacing between the output parts is selected large enough that the output parts are easy to manufacture. Since a plurality of output parts can be operated very effectively, extremely high recording efficiency is achieved using the information output unit according to the invention. Also, it is possible to use a recording medium having a relatively low sensitivity and which is generally cheap in cost, for carrying out a high speed recording.
