The third collection data area 160c for inputting and storing the collection data stored in the OM 127 is provided.

Next, the operation of the analog / digital operation recorder having the electric circuit configuration of FIG. 11 will be described. The CPU 120 in the main body 1 starts its operation when the power is turned on, and when the cartridge 40 is set at a predetermined position, the speed,
The recording operation of the distance and the replacement information is started.

First, the speed recording operation will be described.
When the stopped vehicle starts traveling, the traveling pulse generated by the traveling sensor S is input to the CPU 120 accordingly. The CPU 120 measures the cycle and calculates the vehicle speed based on the measured cycle to obtain the vehicle speed. Next, the number of steps required to move the speed recording needle 18C at the 0 km / h position by the stepping motor 121a to the position corresponding to the speed obtained by this calculation is stored in the ROM 120a based on the 0 km / h position. It is obtained by the table prepared in step 1 or by a predetermined calculation formula.

Then, R indicating the number of steps thus obtained and the number of steps at the current position of the stepping motor 121a
The magnitude relationship with the current value of the up / down counter area formed in the AM 120a and the absolute value of the difference are obtained. If the current value is small, the stepping motor 121a is rotated normally,
If it is larger, the CPU 120 outputs a number of drive pulses corresponding to the absolute value for driving in the reverse direction, and the RAM 120 responds to the output of the drive pulses.
The up / down counter in b is counted up or down. As a result, the speed recording hand is moved to the calculated speed position, and the up / down counter holds the number of steps indicating the current position of the stepping motor 121a as seen from the CPU 120 side supplying the drive pulse. Become so.

On the other hand, the encoder 121g is a speed recording needle 18 which is moved by the rotation of the stepping motor 121a.
A position code representing the position of C by dividing it into a plurality of ranges is generated, and the CPU 120 inputs this. CPU120
Converts the input position code into the corresponding number of steps, and sequentially compares this with the value of the up / down counter in the RAM 120b. As a result of this comparison, when there is a predetermined difference between the two under a predetermined condition, the contents of the up / down counter are replaced with the number of steps corresponding to the position code representing the actual position of the speed recording hand 18C. To update the value indicating. Since the updated step number is the true value of the speed recording needle 18C, it is output through the I / F circuit 128 together with the real-time data every update, and the C value is output through the I / F circuit 165 of the cartridge 40.
By inputting the data to the PU 163 and storing it in the second collection data area 160b of the PROM 160 by the CPU 163, digital data matching the speed recorded on the chart paper can be collected.

The position correction by updating the number of steps described above occurs when some kind of abnormality occurs. The number of times of execution is checked, and when it reaches a certain number or more, it is judged as abnormal and the occurrence time of the abnormality is determined. It is stored in the collected data area 127c in the PROM 127 together with the real-time data shown. There are several possible methods for determining the abnormality. First, the upper limit value is simply determined up to how many times, second is the number of corrections to the number of mileages, and third is the unit time ( For example, it is possible to use the number of corrections and the total number of corrections per hour, and fourthly, the total number of times when the correction interval from the previous time is less than or equal to the set limit time.

A speed-step number conversion unit 120-3 for obtaining the number of steps corresponding to the speed calculated in 20-2, the number of steps from the speed-step number conversion unit 120-3, and the count value of the up / down counter 120-4. The difference of
And a difference determining unit 120-5 that outputs a number of drive pulses corresponding to the difference together with a signal indicating the magnitude, and the stepping motor driver 121 corresponds to the number by the drive pulse from the difference determining unit 120-5. The stepping motor 121a is driven in the forward and reverse directions by the number of times.

The drive pulse output from the difference determining section 120-5 is applied to the up / down counter 120-4, and the drive pulse is counted up or down according to the signal indicating the magnitude of the up / down counter 120-4.
The number of steps of the stepping motor can be known from the count value of. By driving the stepping motor by supplying the stepping motor driver 121 with driving pulses of the number corresponding to the difference between the current step number of the stepping motor viewed from the driving side and the step number corresponding to the calculated speed, The speed recording needle 18C can be driven to a position corresponding to.

However, since there is no guarantee that the speed recording hand 18C has moved to the position corresponding to the actually calculated speed,
A position code corresponding to the position of the speed recording needle 18C is generated in the encoder 121g, and this position code is converted into the number of steps in the position-step number conversion unit 120-6,
The comparison unit 120-7 compares the converted number of steps with the number of steps corresponding to the calculated speed, and when they do not match under a predetermined condition, the position-step representing the true position of the speed recording needle 18C. The content of the up-down counter 120-4 is replaced and updated by the number of steps converted by the number conversion unit 120-6, and the position of the driving-side stepping motor and the actual position are matched.

Therefore, the number of steps at the time of updating is sent to the cartridge 40, and as it is or after being processed, the PR is performed.
By storing it in the second collection data area 160b of the OM 160 together with real-time data from a calendar / clock (not shown), digital data matching the speed recorded on the chart paper can be collected. Further, based on the update of the number of steps, the abnormality determination section 120-8 makes a determination based on a predetermined determination condition, and when it is determined to be abnormal, the collected data area 12 of the PROM 127 is determined.
7c together with real time data. The data in the collected data area is read out when the cartridge is ejected, sent to the cartridge, and stored in the third collected data area 160c in the PROM 160.

Next, the distance recording operation will be described.
When the vehicle starts traveling, the traveling pulse generated by the traveling sensor S is input to the CPU 120 accordingly. CPU
120 counts the number, calculates based on this count value, and when the count value reaches a predetermined value, a distance signal is generated assuming that the vehicle has traveled a unit distance, for example, 100 m.
The distance data area 127b in the ROM 127 is incremented and the distance data area 127b is incremented.
The distance display is caused to display the distance according to the contents of b. Further, when the count value of the traveling pulse reaches a predetermined value, a stepping motor driver 12 that drives a stepping motor that generates a driving pulse and moves the driving pulse
2. Supply to a cartridge 40 and a stepping motor driver that drives a stepping motor that rotates a counter of an integrating distance meter (not shown). The drive pulse sent to the cartridge 40 is independently processed by the CPU 163 in the cartridge 40 on the basis of the pulse to collect distance data.

When the CPU 120 outputs a drive pulse, the CPU 120 determines whether or not the stepping motor driven by this drive pulse is operating to determine whether there is an abnormality. Therefore, by providing a photo interrupter interlocking with a stepping motor that rotates by a drive pulse and comparing the number of rotation pulses generated by the photo interrupter with the number of drive pulses, it is possible to determine the presence or absence of an abnormality. When it is determined that an abnormality has occurred in this determination, the collected data area 127c together with the real-time data
The data can be sent to the cartridge when the cartridge is ejected and stored in the third collection data area in the cartridge.

The distance recording operation of the CPU 120 described above is shown in a functional block diagram as shown in FIG. 15, in which the pulse number counting section 120-11 counts the number of traveling pulses from the traveling sensor S and outputs drive pulses. The distance calculation unit 120-1 is generated according to the count value of the pulse number counting unit 120-11.
2 calculates a distance, outputs a distance signal for each predetermined distance, and increments the distance data area 127b. The contents of the distance data area 127b are used to display the distance on the distance display, and are sent to the cartridge when the cartridge 40 is ejected and stored in the third collection data area 160c.

The drive pulse generated by the pulse number counting section 120-12 is sent to the abnormality determining section 120-13, where it is compared with the operation state signal input from the stepping motor.
The rotation abnormality of the stepping motor driven by this drive pulse is determined. Then, when the abnormality determination unit 120-13 determines that an abnormality has occurred, a calendar / data file is displayed in the collection data area 160c.
It is designed to be stored together with the real time data from the clock 126.

Next, the clock driving operation for rotating the chart paper will be described. The CPU 120 counts the clocks in which the calendar / clock 126 is ticking, generates a driving pulse for each count of a predetermined value, and charts this. It is supplied to the stepping motor driver 124 which drives the stepping motor that rotates the paper, and when this drive pulse is output, it is determined whether the stepping motor driven by this drive pulse is operating to determine whether there is an abnormality. . For this reason, a photo interrupter interlocking with a stepping motor that rotates by a drive pulse is provided, and the presence or absence of abnormality can be determined by comparing the number of rotation pulses generated by this photo interrupter with the number of drive pulses. When it is determined that an abnormality has occurred in this determination, it is stored in the collection data area 127c together with the real-time data, and this data is sent to the cartridge when the cartridge is ejected and stored in the third collection data area in the cartridge. You can

5 is supplied to the stepping motor driver 124 to drive the stepping motor that rotates the chart paper. Then, in order to determine whether or not the stepping motor that is driven when this drive pulse is output is operating and whether or not there is an abnormality, a photointerrupter that interlocks with the stepping motor that rotates by the drive pulse is provided. The abnormality determination unit 12 determines the number of rotation pulses and the number of drive pulses generated by the interrupter.
The comparison is made in 0-16, and the presence or absence of an abnormality is determined from the result. When the abnormality determination unit 120-13 determines that an abnormality has occurred, the collected data area 160c
Is stored together with the real time data from the calendar / clock 126, and the stored data is stored in the third collection data area 160c in the cartridge when the cartridge is ejected.

As described above, the contents of the counter which recognizes the step position of the stepping motor by counting up and down the driving pulse for driving the stepping motor to the position of the step number corresponding to the speed are actually driven. When the position of the stepping motor is different from the position of the stepping motor, the contents of the counter are replaced and updated by the number of steps corresponding to the position code generated by the encoder operating in conjunction with the stepping motor, and the updated number of steps is stored in the cartridge 40. Since it is stored in the data memory 160, the speed data truly corresponding to the recording by the speed recording needle can be collected. By collecting this speed data in relation to the time data, it can be used as a reference when reading the speed value from the speed record on the chart paper before and after this recording, and also the time frequency of occurrence of update can be known. become able to.
