ABSTRACT:
A point recorder has a clock that periodically generates an electrical impulse that is operative through a speaker-type electromagnet to displace a printing element from a holding position wherein an indicator moveable in an indicating direction is spaced from a recording strip to an imprinting position wherein the indicator is pressed against the recording strip. A pawl carried on the printing element is engageable in teeth on a drive roll over which the recording strip is spanned so that each time the printing element moves between its two positions the recording strip is incrementally advanced. The printing element has a bar which presses a needle constituting the indicator against the paper strip where it is spanned over the drive roller so as to record as a point or dot the position of the indicator therealong.
