ABSTRACT:
A pen recorder in which a memory storing data at its addresses necessary for constituting a character is scanned, and the signals for the addresses where the data are stored are converted from digital to analog signals before they are supplied to a recording pen for recording the character. A hold circuit is located forwardly or rearwardly of a digital-to-analog converter so as to hold a previous address signal until a stored next address of the data is scanned, so that a recorded character will be legible.
