When it is determined that the value exceeds a preset alarm point, the value of the measured value signal output from the recording target device is recorded on the chart by an outside area recording line by an outside area recording section. Ru.

(Embodiment) FIG. 1 is a block diagram showing an embodiment of a recorder according to the present invention.

The recorder shown in this figure is equipped with an alarm setting I#l, a sequence circuit 2, a floating mechanism 3, and a motor drive section 4, and the signal (measured value signal) output from the recording target device is set in advance. If the measured value signal has not exceeded the preset alarm point, the motor drive unit 4 is set to line mode and the measured value signal is recorded on the chart as a continuous line, and if the measured value signal does not exceed the preset alarm point. At this time, the motor drive section 4 is set to the point mode and the measured value signal is recorded on the chart as points.

The alarm setting device 1 detects when the signal output from the recording target device exceeds the preset upper limit alarm point or lower limit alarm point, generates an out-of-area detection signal, and sends this to the sequence circuit 2. supply to.

The sequence circuit 2 generates a continuous recording command signal and supplies it to the floating mechanism 3 when the out-of-area detection signal is not supplied from the alarm setting device 1, and also outputs the out-of-area detection signal from the alarm setting device 1. When supplied, a dot recording command signal is generated and supplied to the floating mechanism 3.

The floating mechanism 3 sets the recording method of the motor drive unit 4 to the line mode when the continuous recording command signal is supplied from the sequence circuit 2, and sets the recording method of the motor drive unit 4 to the linear mode when the dot recording command signal is supplied from the sequence circuit 2. When the recording method of the motor drive section 4 is set to a dot mode and a continuous recording command signal or dot recording command signal is not supplied from the sequence circuit 2, the pen tip of the motor drive section 4 is floated and separated from the chart.

When the floating device 113 is in the line mode, the motor drive unit 4 operates the motor based on the measurement value signal output from the recording target device to drive the pen tip and record the measurement value in a continuous line. The signal is recorded on the chart, and when the floating mechanism 3 is set to the dot mode, the pen tip is lowered onto the chart at a predetermined period to record the measured value signal on the chart as a dot.

Further, when the floating mechanism 3 is not set to the line mode or the point mode, the pen tip is floated from the chart and the recording operation of the measured value signal is stopped.

Next, the operation of this embodiment will be explained with reference to FIG.

First, when a signal is output from the device to be recorded and does not exceed the upper limit alarm point or lower limit alarm point set in the alarm setting device 1, a continuous recording command signal is output from the sequence circuit 2 and this signal is output from the sequence circuit 2. The motor drive unit 4 is set to the line mode by the floating mechanism 3.

As a result, the motor drive section 4 operates the motor based on the measurement value signal output from the recording target device side, drives the pen tip, and charts the measurement value signal by a continuous line 8 as shown in FIG. Record on IO.

Additionally, when the signal output from the recording target device exceeds the upper limit alarm point or lower limit alarm point set in the alarm setting device 1, a dot recording command signal is output from the sequence circuit 2 and the point recording command signal is output from the sequence circuit 2. The floating mechanism 3 sets the motor drive section 4 to the point mode.

As a result, the motor drive section 4 lowers the pen tip onto the chart 10 at a predetermined period while operating the motor based on the measurement value signal output from the recording target device, and
Point 9 records the measured value signal on the chart IO.

As described above, in this embodiment, when the value of the measured value signal output from the recording target device exceeds the preset upper limit alarm point or lower limit alarm point, the measured value signal is Since the values are recorded in Char) 10, it is possible to easily distinguish between alarm points and those within and outside a predetermined value, thereby making it easy to confirm and manage the recorded contents.
