ABSTRACT:
A chart recorder of simple construction is provided for moving a strip of chart paper past a marker, the recorder providing a final marked chart strip which is not tightly rolled so it can be easily handled and viewed, with the recorder constructed so the marked chart strip can be viewed prior to opening a security-sealed housing. The chart strip (26) has a leading portion (30) connected to a first end (44) of a long string (42), with the second end (46) of the string mounted on a windup drum (52) that is driven by an ordinary clock drive (56). Thus, as the string is slowly wound up, the string pulls the chart strip along the string path. The recorder includes a guide (64) with a wide guide surface (100) that includes a narrow groove portion (102), and with the guide surface extending in a loop (62) of at least about 180.degree.. The housing (12) can be largely transparent so the marked chart can be viewed from outside the housing prior to opening the housing.
