Claims (1)

[Scope of utility model registration request] In a recorder that inputs the industrial value of a process, calculates it using a range card, and drives a servo motor to record the industrial value on recording paper, a pulse is generated when the industrial value exceeds an arbitrarily set upper or lower limit value. a pulse output section that outputs a pulse output section; a pulse holding output section that holds the pulse output of the pulse output section; and a blinking lamp indicating that the industrial value exceeds the upper limit or lower limit value by the output of the pulse holding output section. a lamp operating circuit that displays a value, and a relay operating circuit that similarly switches the feeding speed of the recording paper from low speed to high speed when the industrial value is exceeded;
A processor monitor for a recorder, comprising a timer circuit that is excited by the output of the pulse holding output section, releases the holding of the output after a predetermined time, and switches the feed speed from high speed to low speed.
