Description

[Brief explanation of the drawing]

Fig. 1 shows an example of the pen-writing oscillograph of this invention, Fig. 2 shows an analog input signal with the recording level set, and Fig. 3 shows a recording example of the conventional pen-writing oscillograph. The figure shown in FIG. 4 is a diagram showing an example of recording of the pen-written oscillograph according to this invention. In the figure, 1 is an input signal amplification section, 2 is a recording signal discrimination section, 3 is a galvanometer, 4 is a recording time counting section, 5 is a time recording section,
Reference numeral 6 represents a paper feed determination unit, and 7 represents a paper feed mechanism. It should be noted that the same or corresponding parts in the drawings are designated by the same reference numerals.

Claims (1)

[Scope of utility model registration request] A pen-writing oscillograph comprising a galvanometer that drives a recording pen using an analog input signal, an input signal amplification section that amplifies the input signal so that the galvanometer can be driven, and a paper feeding mechanism that moves recorded paper. , a recording signal determining unit that determines the magnitude of the analog input signal level and outputs a recording command signal, a recording time counting unit that calculates the recording time from the recording command signal, a time recording unit that records this output, and a paper feeding mechanism. A pen-written oscillograph characterized in that it is equipped with a paper feed discrimination section that issues a paper feed command to the section, and is capable of determining the magnitude of the level of an input analog signal and recording and displaying only signals of a specified magnitude. .
