Abstract

PURPOSE: To separate a pen in an automatic manner from recording paper, in case the latter is broken, thereby to make it unnecessary to monitor a recorder at all times by providing pen separating means having a thermally deformable element.
CONSTITUTION: Under the condition in which a pen point 3a is effecting the normal record in recording paper 10, the pen point 3a and a recording paper carriage 9 are isolated by the paper 10. As a result, a thermally deformable element 5 receives no current. If the paper 10 is broken by any reason so that the pen point 3a comes into contact with the carriage 9, a low current flows through a resistor 8, the pen point 3a and the carriage 9 in this order and is amplified by a current amplifier circuit 11 until it flows into the element 5. As a result, this element is warped in the direction of reference letter Y by the heat generated so that the pen 3 is raised through a lever 6. As a result, the pen point 3a is separated from the recording paper 10.
