Abstract

PURPOSE:To record data without erasing it by outputting all data stored in a phase compensating memory at the time of inputting a record stop signal and then stopping the record of data. CONSTITUTION:At the time of inputting a recording operation stop signal (11), a CPU built in a recorder discriminates whether phase compensating recording is being executed at present or not (12), and when the execution is NO, immediately stops recording (13). At the time of YES, only the recording of a pen A1 is stopped (14), the recording values of pens A2 to An are read out from the phase compensating memory and recorded (16) and the pens ending their recording are successively stopped (17).

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a recording method in a multi-pen recorder.

[Conventional technology]

FIG. 2 is a block diagram showing a general multi-pen recorder. In FIG. 2, A1 to An are pens with different lengths of protruding arms, 1 is a recording paper, 2 is a chart drive device for moving the recording paper 1, and 3 is a pen A1 for displaying a signal waveform on the recording paper 1. -A pen driving device that drives An; 4 is a pen driving signal a;

A CPU that outputs a recording signal (pen up/down signal) b and a chart drive signal C, 5 a RAM as a phase compensation memory that stores data, 6 a ROM that stores a program for operating the recorder, and 7 a A man-machine interface for recorder operation, 8 is a CPU 4. RAM5
．． ROM6. This is a bus for exchanging data between the man-machine interfaces 7.

When the recording signal enters the pen down state, and the chart drive signal C that moves the recording paper and the pen drive signal a that drives the pens A1 to An in accordance with the signals are input to the chart drive device 2 and pen drive device 3. , recording on recording paper 1 is started.

[Problem to be solved by the invention]

In the conventional recording method of a multi-pen recorder that performs pen phase compensation, when a recording operation stop signal (hereinafter referred to as "recording operation stop signal") is input, the operation is stopped immediately, so the shift in the pen position is avoided. There was a drawback that the records corresponding to the amount of time would be erased.

For example, in the relationship between pens A1 and A2 in FIG. 2, the recording for ΔL is lost.

[Failure to solve the problem]

In order to eliminate such drawbacks, the present invention provides a method for a multi-pen recorder that performs pen phase compensation.
When a recording operation stop signal is input, the recording operation is stopped after all the data stored in the phase compensation memory is output.

[Effect]

In the multi-pen recording method according to the present invention, all data that has conventionally disappeared is output onto the recording paper without disappearing.

〔Example〕

FIG. 1 is a flow chart for explaining an embodiment of the multi-pen recording method according to the present invention.

First, when a recording operation stop signal is input (step 11
), the CPU 4 determines whether phase compensation recording is currently being performed (step 12), and if not, immediately stops the recording operation (step 13). If phase compensation recording is being performed, step 12 to step 1
Move to 4.

In step 14, since the pen AI has already finished recording when the recording operation stop signal is input manually, the pen AI
Stop recording.

Next, the chart feeding speed is increased to shorten the time for outputting data (step 15).

Next, the recorded values of the pens A2 to An are read from the RAM 5 and recorded on the recording paper 1 (step 16). Next, the recording operation of the pens that have finished recording is stopped (step 17),
It is determined whether or not the recorded value of the pen An has been completed (step 18). If the process has not been completed, the process returns to step 16 and the operations of steps 16 and 17 are repeated until the process is completed. If the recording operation has been completed, the process moves to step 13 and the recording operation is stopped.

Note that step 15 is unnecessary if there is no need to increase the chart feeding speed.

〔Effect of the invention〕

As explained above, in the multi-pen recording method according to the present invention, when a recording operation stop signal is input, the recording operation is stopped after all the data stored in the phase compensation memory is output. This has the effect that all data, which conventionally disappears when the recording operation is stopped, can be output onto the recording paper without disappearing.
