Abstract
A chart recorder has a drawer containing a supply of chart paper fed to the chart marking area, and an accumulation of marked chart paper received from the chart marking area. A flexible curved guide is connected to the drawer and to a permanent fixed guide and assumes different configurations when the drawer is moved from the chart accumulating position during a recording mode of operation, to a chart loading position when the drawer is moved to position for removing an accumulation of marked chart paper and installing and threading a new supply of chart paper during the chart threading mode. The configuration of the flexible guide aids in threading paper onto a drive roll during the threading mode, and aids in guiding the paper around obstructions and onto the roll during the recording mode.
