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.
Claims17
A flexible chart feeding guide or chute comprising:
- first and second supports at different elevations;
- a chart storage member;
- a sheet spanning a space between said first and second supports and supported by said first and said second supports;
- said first support being connected to said sheet in at least two horizontally spaced points;
- said second support being connected to said sheet in at least two horizontally spaced points;
- said first support being above said second support;
- said sheet being flexible about a line between the two spaced points of the upper support;
- said first and second supports being horizontally movable with respect to each other in a direction perpendicular to the direction of said line between the two points of said first support,
- one of said supports being connected to said storage member and movable therewith with respect to the other of said supports when said storage member is moved from a chart loading position with respect to said supports to a chart use position, and back from said use position to said loading position.
A flexible chart feeding guide or chute comprising:
- first and second supports at different elevations;
- a sheet spanning a space between said first and second supports and supported by said first and said second supports;
- said first support being connected to said sheet in at least two horizontally spaced points;
- said second support being connected to said sheet in at least two horizontally spaced points;
- said first support being above said second support;
- said sheet being flexible about a line between the two spaced points of the upper support;
- said first and second supports being horizontally movable with respect to each other in a direction perpendicular to the direction of said line between the two points of said first support,
- said second support being a chart supply and accumulator means,
- said supply and accumulator means including a box having a supply compartment and an accumulator compartment with said sheet fastened to the upper rear margin of said supply compartment.
In a recorder having chart supply means and chart drive means, and wherein said chart supply means is movable from a position below and behind said drive means to a position below and in front of said drive means, the improvement comprising:
- a flexible guide means movable from one configuration when said supply means is behind said drive means to another configuration when said supply means is in front of said drive means to facilitate introduction of chart material from said supply means into said drive means from in front of said drive means.
