Recorder with self loading feed

A recorder comprising, in combination,

• a case;
• a chart feed mechanism mounted in said case for feeding in incremental steps a chart having substantially equally spaced holes defined in at least one longitudinal edge thereof;
• a recording head mounted in said case and movable in a direction substantially perpendicular to the direction of travel of said chart for recording data on said chart;
• wherein
• said chart feed mechanism comprises a chart stock disposed in said case for storing said chart therein, said chart stock having a chart outlet;
• chart feed means having a discharge roller for discharging said chart from said chart stock, first presser means for pressing said chart against said discharge roller, a feed roller for feeding discharged chart, and second presser means for pressing said chart against said feed roller;
• a first sensor mechanism disposed in said case in confronting relation to said chart outlet for detecting whether said chart is present in said outlet and for applying a drive signal to said chart feed means when said chart is in said outlet;
• and a second sensor mechanism disposed in said case in confronting relation to said chart and positioned in a path of travel of said chart between said discharge roller and said feed roller, said second sensor mechanism being arranged to detect whether said chart is in said path a fixed period of time after said chart feed means has started being driven by said drive signal from said first sensor mechanism, to keep said chart feed means driven for a certain period of time when the chart is in the said path, and to apply a signal to inactivate said chart feed means when said chart is not present in said path.
