2. Description of the Related Art As a kind of recorder, a carriage equipped with a recording head for dot recording is raster-scanned in the width direction of the recording paper, and when the recording head reaches a recording position, the carriage is stopped and analog input is performed. Some are configured to dot record the magnitude of the signal.

FIG. 4 is a schematic structural explanatory view of an example of such a conventional recorder. In FIG. 4, 10 is a recording paper 20.
Is a platen wound around, and is rotationally driven at a predetermined speed by, for example, a step motor and a gear. Thirty
Is a carriage, and is reciprocated in a direction orthogonal to the feeding direction of the recording paper 20 by a step motor, for example. FIG. 5 is a configuration explanatory view showing a main part of a concrete example of such a carriage 30. The carriage 30 is composed of a main body and a cover, but in FIG.

In FIG. 5, a bearing 3 is provided near one end of the main body.
1, a wire hammer 33 is inserted into the bearing 31 via a coil spring 32 so as to be vertically displaceable,
The yoke 34 is arranged near the other end and the yoke 3
A coil 35 and an armature 36 are laminated and arranged on the upper part 4 to form a magnetic circuit. A leaf spring 37 is attached to the inner surface of the cover and acts as a holding spring for the armature 36. The leaf spring 37 is attached so that its free end substantially faces the end surface of the yoke 34 via the armature 36. The armature 36 is fitted in a guide 38 formed so as to guide the armature 36 to the middle part of the inner surface of the cover so as to be vertically displaceable,
One end presses the end of the wire hammer 33 and the other end is pressed by the leaf spring 37 so as to face the yoke 34 and the coil 35. A protrusion 39 is provided on the inner surface of the cover in the vicinity of the plate spring 37 so as to protrude from the free end of the plate spring 37, and is fitted to the protrusion 39 near the end of the armature 36 on the plate spring 37 side. A hole 40 is provided, and the cover is mounted so as to be superposed on the main body with the leaf spring 37 and the armature 36 mounted. As a result, the carriage 30 as shown in FIG. 5 is configured, and the armature 36 is provided with the yoke 3 depending on whether the coil 35 is excited or not.
4 and the contact portion with the leaf spring 37 are rotationally displaced about the rotational center, and the wire hammer 33 is selectively displaced in a substantially vertical direction. Reference numeral 41 is a guide shaft for guiding the carriage 30 in a direction orthogonal to the feeding direction of the recording paper 20.

Referring again to FIG. 4, reference numeral 50 denotes an endless color ink ribbon dyed in a plurality of colors in the width direction. The end portion of the ink ribbon cassette 51 is movable in a fixed direction while facing the effective recording width of the recording paper 20. It is stored. Reference numeral 52 is a knob for manually feeding the ink ribbon 50. As shown in FIG. 6, the ink ribbon cassette 51 is detachably attached to the cassette holder 60 from the front of the apparatus main body. The cassette holder 60 is swingably attached to the upper part between the left and right both side plates on the front surface of the apparatus body (not shown) via shafts 61 and 62 which are planted on the left and right side surfaces. The upper side of the cassette holder 60 is bent into an L shape to form a guide 63 facing the upper surface of the ink ribbon cassette 51, and the lower side of the cassette holder 60 has a stepped portion 53 formed on the lower front surface of the ink ribbon cassette 51 as shown in FIG. A leaf spring 64 having a bent portion for fitting and holding by elastic force is fixed by, for example, a rivet so as to face the guide 63, and the ink ribbon 50 is moved to the back surface via a mounting plate 65. Motor 66 for
Is attached. The rotation output of this motor 66 is
The end of the knob 52 is transmitted to a drive shaft 67 that is detachably fitted through a gear train (not shown). The cassette holder 60 is rotationally driven in the reciprocating direction by, for example, a motor and a sector gear. This allows the ink ribbon 5
0 will be swung about the swing shafts 61 and 62 of the cassette holder 60 along the feeding direction of the recording paper 20.

The recording operation of the apparatus thus configured will be described. First, when the power is turned on, the carriage 30 once moves to the 0% side (to the left), and drives a reference position signal generating means (not shown) including, for example, a lever and a photo sensor to generate a reference position signal. And stop at the reference position. On the other hand, the cassette holder also rotates to the reference position, drives a similar reference position signal generating means (not shown) to generate the reference position signal, and stops at the reference position. As a result, the carriage 30 and the ink ribbon 50 are initialized.

Next, the cassette holder is rotationally driven from the reference position by a predetermined angle so that the color band of the ink ribbon 50 assigned to the first channel faces the wire hammer 51. After the cassette holder is rotationally driven from the reference position by a predetermined angle in this way, the carriage 30 is moved from the reference position (0%) toward the 100% side at a constant speed. Then, the carriage 30 moves to the first position during the movement.
When the recording position of the channel is reached, the carriage 30 is stopped, the coil 35 is selectively excited, and the dot hammer recording operation by the wire hammer 33 is performed. As a result, the size of the measurement signal of the first channel is dot-recorded on the recording paper 20 with the predetermined color assigned to the first channel. When the dot printing is completed, the carriage 30 moves to the 100% position and stops.

With the carriage 30 stopped at the 100% position, the cassette holder is moved from the position of the first channel to a predetermined position so that the color band of the ink ribbon 50 assigned to the second channel faces the wire hammer 33. It is driven to rotate by an angle. In this way, after the cassette holder is rotationally driven by a predetermined angle from the predetermined position assigned to the first channel, the carriage 30 is moved from the 100% position to the 0% side at a constant speed. Then, when the carriage 30 reaches the recording position of the second channel during the movement, the carriage 30 stops,
The coil 35 is selectively excited to perform the dot recording operation by the wire hammer 33. As a result, the size of the measurement signal of the second channel is dot-recorded on the recording paper 20 with the predetermined color assigned to the second channel. When the dot printing is completed, the carriage 30 moves to the 0% position and stops.

Thereafter, the same operation is repeated by the number of color bands of the ink ribbon 50, and the magnitudes of the measurement signals of a plurality of channels are recorded in an analog manner in a dot pattern of a predetermined color assigned to each channel. With this configuration, one wire hammer 33 is attached to the carriage 30.
Is provided, and the number of parts can be significantly reduced,
The size and weight of the carriage 30 can be reduced, and the cost can be reduced.

Further, since the carriage 30 can be downsized, the effective recording width of the recording paper 20 becomes relatively wide,
The width of the device required to secure a constant effective recording width can be made narrower than in the past. Further, since the carriage 30 becomes light, the carriage 30 can be moved at high speed by a relatively small motor, power consumption can be saved, and the amount of heat generation can be reduced.

Further, it is possible to reduce the deterioration of the recording quality due to the dead zone due to the insufficient rigidity of the driving reel and the insufficient torque of the driving motor. Further, the ink ribbon cassette 51 can be replaced from the front side of the apparatus, which facilitates the replacement work. However, according to such a conventional configuration, only one channel is recorded in the process in which the carriage 30 travels from one end to the other end. For example, in order to perform six-channel recording with 6 colors, the carriage 30 is used. Must be run 6 times, the recording cycle of each channel becomes long, and high-speed recording cannot be performed. Specifically, if it takes 5 seconds for the carriage 30 to run once, recording for 6 channels of 6 colors will take 30 seconds, and the recording cycle for each channel will be 30 seconds.

Therefore, the applicant of the present invention proposes to realize high-speed recording capable of dot recording of measurement data of a plurality of channels by one raster scan while making use of the advantages of such a structure, as disclosed in Japanese Patent Application No. -175545 "Color Dot Recorder" filed. FIG. 8 is a block diagram showing an embodiment of such a color dot recorder, and the same parts as those in FIGS. 4 and 5 are designated by the same reference numerals. Reference numeral 70 denotes an input terminal for a plurality of channels, which is connected to the input switching mechanism 71. The output signal of the input switching mechanism 71 is applied to the A / D converter 73 via the preamplifier 72, and the output data of the A / D converter 73 is applied to the bus 74. These input switching mechanism 71, preamplifier 72 and A / D converter 73 are controlled by a microprocessor 75 via a bus 74. RO for microprocessor 75
The M76 and the RAM 77 are connected. In addition, RO
An operation program and fixed data are stored in M76. The RAM 77 stores measurement data and calculation data. Reference numeral 78 is a keyboard, and 79 is a display, which are connected to the bus 74 via an interface 80. Bus 7
4, a driver 82 that drives a motor 81 that moves the carriage 30, a driver 84 that drives a motor 83 that swings the ink ribbon cassette 51 that stores the ink ribbon 50 to select a color, and runs the recording paper 20. Driver 86 for driving motor 85, ink ribbon 50
A driver 88 that drives a motor 87 that moves the motor, a driver 89 that selectively drives the wire hammer 33, and the like are also connected.

Data processing in such a configuration will be described. A recording data storage area is allocated to a part of the RAM 77, and 1 byte is allocated to each position of the minimum movement step of the carriage 30 over the effective recording width of the recording paper 20 to store the recording data.
For example, when the effective recording width of the recording paper 20 is 100 mm and the movement resolution of the carriage 30 is 0.1 mm, 1000 + α (byte) is allocated as shown in FIG.
Here, the α byte is a portion corresponding to the left and right margin lengths of the effective recording width of the recording paper 20.

Then, each bit position b0 to b of each byte
7, the colors to be recorded as shown in FIG. 10 (in this embodiment, purple for b0, black for b1, green for b2, blue for b3, brown for b4, red for b5, b6 , B7 are blank)
Is assigned and "1" is stored in the bit position of the corresponding color when recording is performed, and "0" is stored in each bit position when recording is not performed. In the example of the byte shown in FIG. 10, dots are recorded in "purple" color.

The print data stored in the print data storage area is generated based on the measurement data converted and output from the A / D converter 73 for each channel and the color designation data previously assigned to each channel. To be done. That is, a measurement data storage area is assigned to a part of the RAM 77, and recording span data, recording zone data, partial compression data, 0 set for the measurement data of each channel converted by the A / D converter 73. % Position or 100%
The calculation result of the recording position calibration calculation and the recording color correction calculation based on the position calibration data is the position on the recording paper 20 having the recording resolution (0.1 mm in this embodiment) based on the home position. Converted to data and stored.

A part of the ROM 76 or the RAM 77
A color designation data storage area is provided in a part of the area, and the color designation data assigned to each measurement channel is stored therein. Here, when stored in the ROM 76, the allocation relationship between each channel and the recording color is fixed, and
If it is stored in 77, it can be changed appropriately. Then, the microprocessor 75 generates recording data as shown in FIG. 10 for each measurement data based on the measurement data stored in the measurement data storage area and the color designation data stored in the color designation data storage area, Transfer and store to the corresponding address in the recording data storage area.

Further, a part of the RAM 77 is provided with an area for storing the current position data of the carriage 30 and an area for storing point data indicating the address of the recording data storage area. The areas provided in the RAM 77 are summarized as shown in FIG. Figure 1
2 is a flow chart showing the flow of the dot recording operation of FIG.

First, recording data as shown in FIG. 10 is set in the recording data storage area of the RAM 77 in the order of recording positions (step). In this state, it is assumed that the carriage 30 is located at the home position at the left end or the right end of the moving range, and the swing position of the ink ribbon 50 is also located at the home position angle at which the recording result is most readable. The carriage 30 is moved to the recording position according to the recording data (step). When the carriage 30 reaches the recording position, the ink ribbon 50 is swung according to the recording data, and the wire hammer 33 is made to face a predetermined color band (step). The wire hammer 3 with the predetermined color band of the ink ribbon 50 facing the wire hammer 33.
3 is driven to perform dot recording (step). After performing the dot recording, the ink ribbon 50 is returned to the home position (step). The steps from step to step are sequentially repeated for all print data stored in the print data storage area (step). Then, when the dot recording is completed for all the recording data, the carriage 30 is moved to the other end in the moving direction (step), and the dot recording for one cycle is completed.

FIG. 13 is a timing chart of each part related to the operation of FIG. 12, (a) shows the carriage motor 8
1 shows the movement and stop of the carriage 30 by (1), (b) shows the swing shift of the ink ribbon 50 by the ribbon shift motor 83, and (c) shows the drive timing of the wire hammer 33 by the wire hammer driver 89. As is apparent from FIG. 13, while the carriage 30 is stopped at the predetermined recording position on the recording paper 20, the color selection and the return to the home position by the swing shift of the ink ribbon 50 from the home position are performed. When the color of the ink ribbon 50 is selected and stopped, the wire hammer driver 89 selectively drives the wire hammer 33 to perform dot recording on the recording paper 20 in a predetermined color. become.

FIG. 14 is a timing chart of the data processing of FIG. For example, when recording 6 dots with an effective recording width of 100 mm and the measurement cycle is 2.5 seconds,
As shown in (a), the A / D conversion operation of the measurement data of 6 dots every 2.5 seconds and various arithmetic operations on the conversion data are performed, and the measurement data to be recorded by the movement of the carriage 30 this time is measured. It is stored in the data storage area. And
Recording data is generated based on the measurement data and the color designation data, and is stored in the recording data storage area.

On the other hand, the dot recording operation is started after the recording data is stored in the recording data storage area in the first measurement cycle as shown in (b). Here, the recording operation is
As described above, since the mechanical operation sequence of moving and stopping the carriage 30, swinging the ink ribbon 50, and driving the wire hammer 33 is performed, it takes a longer time than the measurement operation. Therefore, in this embodiment, the recording operation is set to be performed once at least four measurement cycles. That is, in the case of FIG. 14, the measurement data of the measurement cycle with diagonal lines is recorded in dots. In addition,
Although the measurement data in other measurement cycles are not recorded as dots, the display of the measurement data on the display and the alarm detection operation are executed. In dot recording, the average value, the maximum value, and the minimum value of a plurality of measurement periods measured during the recording period may be combined appropriately.

When dot recording is performed while moving the carriage 30 from the left end to the right end, for example, the carriage 30 is moved step by step, and when the home position is crossed, the start address of the print data storage area shown in FIG. Read the contents and judge whether to record or not. Similarly, every time the carriage 30 is moved to the right end by one step, the contents of the next address are read and the presence / absence of recording is repeatedly determined.

The flow of such operation is shown in the flow chart of FIG. Initially, the current position data stored in the current position data storage area is 0, and the point data stored in the point data area is the start address of the recording data storage area (step). From this state, the carriage 30 is moved one step (step). Along with this, the current position data stored in the current position data storage area is incremented by 1 (step). Sequentially, it is determined whether or not the carriage 30 has passed the home position (step), and if the carriage 30 has passed the home position, the point data is incremented by 1 (step). Based on the point data, the print data is read from the corresponding address in the print data storage area (step), and the presence or absence of the print data is determined (step). Then, if there is print data, the processes from step S12 to S12 of FIG. 12 are executed to perform dot printing (step), and if there is no print data, the step is skipped. This procedure is repeated until the right end is reached.
If the home position is not passed in step, the process is skipped to step. After reaching the right end in step, a recording paper feeding operation or the like is executed.

In the above description, the example in which the size of the measurement data of a plurality of channels is recorded in an analog manner has been described, but a character symbol or the like may be recorded in a digital manner.
For digital recording, a part of the RAM 77 is shown in FIG.
The print data is stored in the print data storage area having the data format as shown in FIG. 3, and the print data stored in the print data storage area is expanded and stored in the print data storage area as shown in FIG. FIG. 17 shows an example in which the character pattern of “A” represented by 5 × 7 dots is stored. In this case, the character pattern can be dot-recorded by moving the carriage 30 seven times. The numbers in the dots represent the recording order when the recording paper 20 is run in the direction of the arrow.

Specifically, the designated color is the wire hammer 33.
After shifting the ink ribbon 50 to face the
The wire hammer 33 is moved when the carriage 30 is moved and the point data is incremented by +1 and the position to be printed is reached according to the content of the read print data.
Selectively drive. At this time, the ink ribbon 50
Therefore, the carriage 30 is not stopped because the shift is unnecessary.
The return of the ink ribbon 50 to the home position is performed when the carriage 30 reaches the end position. Here, the time required to record one row of dots for digital printing is
It takes about 2 seconds because there is no shift of the ink ribbon 50 during the movement of the carriage 30.

Here, it is assumed that the carriage 30 is moved 100 mm at 800 PPS, and that it takes 0.8 seconds to select the color of the ink ribbon 50 and to return to the home position, respectively. Assuming that printing is possible, the minimum time required to perform 6-dot dot recording with 6 colors and digital printing for one line is the carriage movement time of 1.3 seconds, and the total stop time of the carriage at the recording position. Is 4.8 seconds, and the digital printing time is 2 seconds, which is a total of 8.1 seconds. Assuming that the recording cycle satisfies an integer multiple of the measurement cycle, the recording cycle becomes 10 seconds, which is four times as long as 2.5 seconds, which can be shortened to less than half of the conventional one.

As described above, according to the color dot recorder of FIG. 8, the size of the analog input signal of a plurality of channels can be dot-recorded in a predetermined color assigned to each channel by one raster scan.

[0028]

However, as described above, according to the conventional method, the size of analog input signals of a plurality of channels is dot-recorded in a predetermined color assigned to each channel by one raster scan. In the recorder, the time required for recording including the carriage stop time at each recording position for recording the magnitude of the analog input signal is controlled so as to be always constant irrespective of the recording cycle as shown in FIG. Was there.

Therefore, for example, when the recording cycle is 10 seconds as in the above-described specific example, if the carriage raster-scans from the left end (right end) to the right end (left end) and stops at the right end (left end), The stop time at the right end (left end) of the carriage is about 2 seconds when digital printing is performed, which is longer than the stop time of the carriage at each recording position. This tendency becomes more remarkable as the recording cycle becomes longer. For example, when the recording cycle is 90 seconds, the stop time at the right end (left end) of the carriage becomes about 82 seconds when there is digital printing.

As a result, when the flag (index) is attached to the carriage so as to be located on the scale plate and the size of the measurement data is read from the position of the flag on the scale plate, the right end of the carriage ( If the stop time at the left end) is long, it may be mistaken for the measurement data to be out of range. Further, since the stop time of the carriage at each recording position is shorter than the stop time at the right end (left end) of the carriage, it is difficult to read the size of the measurement data from the position of the flag on the scale plate.

The present invention solves such a conventional problem, and an object thereof is to realize a raster scan type recorder capable of obtaining highly accurate information from the stop position of the carriage. .

[0032]

SUMMARY OF THE INVENTION According to the present invention, a carriage on which a recording head for dot recording is mounted is raster-scanned in the width direction of a recording sheet and stopped when the recording head reaches a recording position. In a raster scan type recorder that records the magnitude of an analog input signal in dots, the carriage stop time at the recording position is variable according to the recording cycle and the number of recording channels.

[0033]

In the recorder of the present invention, the carriage stop time at each recording position becomes longer in proportion to the recording cycle and becomes shorter as the number of recording channels increases, and the carriage stop time at the right end or the left end becomes the number of recording channels. However, the time is almost constant regardless of the recording cycle.

As a result, the carriage stop time at each recording position becomes longer and the carriage stop time at the right end or the left end becomes shorter than that of the conventional configuration, and measurement data can be easily obtained from the carriage stop position at each recording position. In addition, it is possible to prevent the stop state of the carriage at the right end or the left end from being mistaken for the measurement data being shaken.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention can be applied to the recorder shown in FIG. 8, for example, and the present invention will be described below with reference to FIG.
In a part of the RAM 77 used in the present invention, in addition to the area shown in FIG. 11, an area for storing the recording cycle data necessary for calculating the waiting time data at each recording position and the recording paper feed amount data. And an area for storing waiting time data at each recording position per channel calculated. Here, the recording cycle is determined by the recording mode and the recording paper feed speed, which is to keep the recording cycle constant regardless of the recording paper feed speed or to change it in synchronization with the recording paper feed speed. Is determined by the recording cycle and the feeding speed of the recording paper.

After storing the data necessary for calculating the waiting time data at each recording position in the RAM 77, the waiting time WT at each recording position of the carriage 30 per channel is calculated based on the following equation: RAM for calculation results
It is stored in a predetermined area of 77. WT = {recording cycle- (carriage running time + ribbon selection / recording time + recording paper feed time + margin)} / number of recording channels Carriage running time: time required for the carriage to move a full span, full span distance And the moving speed of the carriage.

Ribbon selection / recording time: selection of a ribbon color assigned to a channel, dot recording by driving a wire hammer, and a time corresponding to the number of recording channels required to return the ribbon color to a reference color. It is a sum and can be obtained from the shift amount and shift speed of the ribbon and the programmed drive time of the wire hammer.

Recording paper feed time: It can be obtained from the recording paper feed amount and the recording paper feed speed. Margin: Margin set appropriately The flow of control of the recording operation according to the present invention is as follows. Carriage 3 per channel before starting recording operation

The carriage 30 is moved from the left end (right end) to the first recording position and stopped. The ribbon color assigned to the measurement channel is selected to face the wire hammer 33. The wire hammer 33 is driven to perform dot recording.

The ribbon color is returned to the reference color (reference position). The carriage 30 is stopped by the waiting time data at each recording position of the carriage 30 per channel stored in the RAM 77. Specifically, it can be realized by a hardware or software timer. Repeat from to the number of measurement channels to be recorded.

The carriage 30 is moved to the right end (left end) and stopped. The recording paper 20 is intermittently fed by a predetermined amount and stands by until the start of the next recording. As a result, the stopping time of the carriage 30 at each recording position is longer than that of the conventional one, although it changes in relation to the recording cycle, the number of recording channels, and the recording paper feed speed. Regardless of the number of recording channels and recording paper feed speed, the fixed time is much shorter than in the past.

FIG. 1 is an explanatory diagram of these time relationships.

As is apparent from FIG. 1, the movement of the carriage 30 and the recording operation by the wire hammer 33 in the present invention are exactly the same as in the conventional case, and the recording quality does not deteriorate as compared with the conventional case. In addition, according to the configuration of the present invention, the stop time of the carriage 30 at each recording position becomes longer and the stop time of the carriage 30 at both ends becomes shorter than in the conventional case, and the stop position of the carriage 30 at each recording position becomes shorter. The measurement data can be easily read from the carriage 30 at the right end or the left end.
It is also possible to prevent mistakenly recognizing the stop state of as being out of measurement data.

Regarding the display on the display 79, for example, as shown in FIG. 2, the measurement channel number currently recorded and the measurement data value thereof are displayed in combination in synchronization with the recording operation to monitor the measurement data. Will be easier. In this case, the measurement channel number to be recorded next when the carriage 30 starts moving is displayed. After the recording of the last channel is completed, for example, the fact that the recording operation is in progress may be displayed by "rcd on" or the like.

When digital recording is included in the recording cycle, the time required for digital printing is included in the processing time for recording as shown in FIG. Carriage 30
The stop time of can be controlled in the same manner as in FIG.
