Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a recorder for recording the waveforms of a plurality of input signals with a plurality of recording pens. More specifically, by delaying each input signal appropriately, the phase of the recording result in the paper feeding direction is synchronized. It concerns a recorder.

[0002]

[Prior art]

 FIG. 2 is a diagram showing a recorder for recording a plurality of input signals by a plurality of recording pens, which conveys recording paper by rotating a platen by a recording paper feed drive control unit. At the same time, a plurality of recording pens that are slidably provided in the direction orthogonal to the direction in which the recording paper is conveyed, that is, the longitudinal direction of the platen, and its sliding mechanism can be moved independently by each recording drive control unit. The recording pens are provided at a predetermined interval in the paper feed direction so that they do not collide with each other during movement (in the case of the recorder shown in the figure, the outer circumference of the platen is They are arranged in a radial pattern.)

When performing recording with this recorder, recording data is created by input signals from a plurality of signal input units, and based on the recording data, the corresponding recording drive control units are independently driven and controlled. Then, record.

Further, in such a recorder, when recording is simultaneously performed by a plurality of recording pens, the recording points of the signals input at the same time are only a predetermined interval where the recording pens are provided. The recording paper is misaligned in the direction of the recording paper time axis (recording paper feed), making the recording results difficult to see. Therefore, in order to display the recording results on the same time axis, in this type of recorder, the recording pen located furthest upstream in the recording paper feed direction is used as the reference recording pen. Corrects the mechanical displacement of the recording pens by delaying and transmitting the recording data to the control unit based on the distance between each recording pen and the reference recording pen and the feeding speed of the recording paper. It has a phase-locked mode that performs recording by using the same method, and is configured to match the recording results of each recording pen on the time axis.

[0005]

[Problems to be solved by the device]

 In this type of phase-locked recorder, in addition to multiple recording pens for recording measurement (input) signals, a recording head of dot impact or thermal transfer method is used for recording paper in the same manner as other recording pens. Some of them are provided so as to be movable in a direction orthogonal to the direction in which they are conveyed, and are configured to be able to perform various types of printing such as printing of measured values as numerical values or printing of measurement times.

However, since this recording head for printing is also provided at a predetermined interval with respect to the recording pen so as not to collide with other recording pens during movement, recording by this recording head for printing , The phase difference (distance) from the reference recording pen causes a shift in the direction of the time axis, and even if the measured value or measured time at a specific time is printed by this recording head, it is necessary to consider the recording result. There is a drawback in that consideration must be given to the deviation of each recording position.

In view of the above-mentioned drawbacks, the present invention aims to provide a recorder capable of making waveform recording by a plurality of recording pens and recording positions by a recording head for printing coincide with each other in a recording paper feed direction. And

[0008]

[Means for Solving the Problems]

 In order to achieve the above object, in the recorder of the present invention, a plurality of units are provided at a predetermined interval along the feeding direction of the recording paper and are independently movable in a direction orthogonal to the feeding direction of the recording paper. The recording pen, the recording head for printing that can be moved independently of the recording pen in the direction orthogonal to the feeding direction of the recording paper, and the recording data created based on the measurement data from the signal input unit A control circuit for driving and controlling the recording pens and the recording head for printing and the plurality of recording pens are appropriately arranged based on the relative positional deviation of each recording pen with respect to the recording head for printing and the feeding speed of the recording paper. The control circuit is provided with delay means for setting the delay amount so that the drive is delayed.

[0009]

[Action]

 When performing recording by the recording head for printing in the phase synchronization mode recording, the delay means sets a delay amount in the control circuit so as to correct the relative positional deviation of each recording pen with respect to the recording head for printing.

[0010]

【Example】

 The recorder of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram showing a recorder of the present invention. In the figure, 1 is a signal input section for amplifying a plurality of analog signals input to a plurality of input terminals into digital data and converting them into digital data. 2 is a calculation section for creating recording data based on each input signal. 3 is a recording unit for recording based on the generated record data, 4 is an operating unit for performing various settings, 5 is a display unit for displaying various setting states or the state of the recorder, and 6 is each device. A power supply circuit for supplying power to the parts, and a signal line connection circuit 7 for connecting each part of the device. The signal input unit 1 includes amplifiers 111 to 11n for amplifying the analog signals input to the respective input terminals (each of the input channels CH1 to CHn), and A / D converters 121 to 121 for converting the analog signals into digital signals. It is composed of 12n. The arithmetic unit 2 is composed of a control circuit 21 such as a CPU, a ROM 22 for storing and holding programs, a RAM 23 for storing measurement data sequentially input from the signal input unit 1, and a delay circuit 20. Further, the recording unit 3 includes recording drive control units 311 to 31n and recording pens 321 to 32n corresponding to the respective input terminals, a print control unit 33 for printing measurement values or measurement times, dot impact or thermal transfer. It is composed of a recording head 34 for printing such as a method, a recording head drive controller 35 for printing, a paper feed drive controller 36 for feeding recording paper, a pulse motor 37, a platen 38, and a recording paper 39.

The control circuit 21 divides the memory area of the memory 23 into signal input channels, and the divided memory areas each contain the measured data n steps before the latest measured data in each channel. It is configured to be sequentially stored and held. That is, the control circuit 21 controls the measurement data to be written in the storage area of each channel of the memory 23 at the write timing of the measurement data according to the recording paper feeding step, ie, the measurement data n + 1 steps before (ie, the measurement data stored and held). The latest measurement data of each channel is stored in the address where the oldest data is stored, and the measurement data is rewritten sequentially at each write timing.

Next, the operation of this recorder will be described. First, prior to recording, the operation unit 4 is operated to set the paper feed speed and the recording mode, that is, the normal recording mode in which real-time recording is performed by each recording pen, and the positional deviation of each recording pen is corrected. Select and set the desired recording mode among the phase synchronization modes for recording.

When the normal recording mode is set, the control circuit 21 sequentially stores the measurement data sequentially input from the A / D converters 121 to 12n of the signal input unit 1 in respective storage areas of the corresponding memory 23. The measurement data is stored, and at the same time, the measurement data is read out to calculate the print data, and the print drive control unit 31 and the paper feed drive control unit 36 are controlled based on the print data to record the measurement signal in real time. .

Next, an example of the recording operation when the phase synchronization mode is set will be described. In this recorder, the phase difference of each recording pen from the set paper feed speed is as shown in FIG. 2, the first recording pen 321 for one channel is used as a reference pen, and the other recording pens have 30 steps respectively. Further, a case where the phase difference from the recording head 34 for printing is 240 steps as compared with the reference pen will be described.

When recording is performed in the phase synchronization mode in this recorder, the delay unit 20 has 240 steps for the first recording pen 321 for one channel recording and 270 steps for the second recording pen 322. Similarly, a delay amount of 240 + 30 * n steps is set in the control circuit 21 for the nth recording pen 32n. As a result, the control circuit 21 reads the measurement data for 1-channel recording from the address 240 steps before the latest measurement data writing address in the corresponding memory area, and the measurement data for 2-channel recording is Read from the address 270 steps before the latest measured data write address in the corresponding memory area. Similarly, the measured data for n channel recording is 240 + 30 * n steps before the latest measured data write address in the corresponding memory area. The address is read from each address, recording data is created from the measurement data read from each address, and each drive control unit 31 is controlled based on this recording data to perform recording. As a result, the phase of the recording by each recording pen is corrected with the printing recording head 34 as a reference.

In this phase synchronization mode recording, when the value of the measurement data is printed numerically by the printing recording head 34, the control circuit 21 sends the measurement data from a predetermined address set in each memory area of each channel. At the same time as reading, the latest measurement data of each channel is read to create recording data, the print control unit 33 is drive-controlled based on this recording data, and the printing recording head 34 records the measurement data in numerical values. .

At this time, since the recording of the measurement data by each recording pen 32 is corrected with respect to the phase shift amount from the recording head for printing 34, the measurement recording of each channel and the numerical value by the recording head for printing are , Will be recorded in agreement on the time axis.

Further, the delay means in the present embodiment is configured to change the reading timing of the measurement data with respect to the control circuit, but a predetermined amount of recording data is accumulated in the preceding stage of the recording drive control section 31 of the recording section 3. A delay circuit for transmitting after that may be provided.

[0019]

[Effect of device]

 As described above in detail, in the recorder of the present invention, the waveform recording by the plurality of recording pens and the recording position by the recording head for printing can be matched in the recording paper feeding direction. There is no need to consider the positional deviation of the recording pen when doing this, and the effect is that the instantaneous value of the measurement value and the measurement time can be printed according to the time axis of the recording pen.
