[Field of Invention]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a driving recorder for recording information on a traveling speed and a traveling distance (running distance) of a vehicle on a recording ground, and a recording medium mounting apparatus used for the driving recorder.

[Private Technology]

Large trucks, buses and taxis are provided with a driving recorder for recording vehicle information such as driving speed and driving distance according to the rules. This is to provide the data required by the operator, the operator who manages the operation or the labor, or the supervisory authority without technical difficulties and as evidence of the work contents or working hours.

The operator uses these data to perform economic maintenance of the vehicle, and the Supervisory Service is used to check the vehicle operation or compliance with the working time standard.

A driving recorder of this kind currently in use is generally composed of a cylindrical shape provided with a speedometer and a odometer in front, and a circular chart can be mounted in parallel with a dial such as a speedometer. A lid portion is rotatably provided by a hinge in the main body of the driving recorder in which the circuit board and the like are housed. Opening the lid allows the chart to be attached and detached.

On the chart paper which is recorded by such a driving recorder, a large amount of analogues are recorded such as traveling speed, traveling distance, and vehicle driving status. Accordingly, the driver can easily prepare a driving log. The chart is easy to handle and can record a large amount of information, which can be read at any time and automatically read if necessary equipment is installed. Therefore, it is suitable for the transmission system of the vehicle.

However, in the case of analog recording on chart paper, a problem arises when numerical values cannot be obtained accurately from such recording. In order to avoid errors, some amount of time is required and much experience is required for evaluation. In addition, since the operation time of one revolution is 24 hours, the resolution of the speed recording is very low, which requires sufficient evaluation experience and expensive measuring means.

Under these circumstances, a digital driving recorder having a data card with a built-in memory and capable of digitally recording driving data by inserting the card into an insertion hole of the driving recorder has been proposed. This digital tachograph has been developed mainly for the use of post-treatment at the user's office for labor and maintenance.

Numerous pieces of data relating to continuous recording of driving and running conditions are recorded on a data card by processing such as compression. As a result, these digital systems are less advantageous than analog in terms of reliability of continuous recording of driving conditions and general checking capability, that is, the ability to check the entire data at any time and anywhere.

By combining only the advantages of these two tachographs, it is possible to construct a better tachograph and this utilization system. However, to realize this, it is necessary to ensure that there is no difference between the contents of the chart paper and the contents of the memory data.

[Summary of invention]

Therefore, the present invention maintains the advantages of analog chart recording, and extracts and collects data necessary for management for convenient data post-processing and records it in the digital data memory, and there is no difference between the chart recording contents and the memory data recording contents. The main objective is to provide an analog and digital tachograph that can guarantee the reliability of the system.

The present invention is also advantageously applied to an analog digital driving recorder, and an object thereof is to provide a recording medium mounting apparatus for mounting a recording medium consisting of a chart paper and a memory to a recording unit.

In order to achieve this object, the tachograph according to the present invention comprises a cartridge in which the chart is accommodated; The cartridge includes a main body including a cartridge detachment mechanism for detachably storing the cartridge, a clock mechanism for rotating the chart paper in the cartridge, and a recording mechanism for mechanically recording vehicle information on the chart paper. Is characterized in that it comprises cartridge side storage means for electrically recording therein vehicle information corresponding to the recording mechanically performed by the recording mechanism 18C on the chart paper.

In the configuration of FIG. 1, the chart paper 50 in the cartridge 40 mounted on the cartridge detachment mechanism of the main body 1 is rotated by a clock mechanism, and the vehicle information is mechanically recorded on the chart paper by the recording mechanism. At the same time, vehicle information corresponding to the recording performed by the recording mechanism mechanically on the chart paper is electrically stored in the cartridge side storage means 160 incorporated in the cartridge. Therefore, the analog recording on the chart paper and the digital recording in the storage means can be reliably and integrally handled by a single cartridge. After the vehicle information is processed by the processing means 163 in the cartridge, it is recorded in the cartridge side storage means, so that by changing the processing in the processing means, another digital record may be obtained and retained in the main body.

When the lid 43 is opened and closed, attachment and detachment of the chart paper is possible. It is preferable to detect the opening and closing of the lid by the detection means 166, and it is recorded in the cartridge side storage means, so that the opening and closing state of the lid can be known by checking this record.

The abnormality of the clock mechanism and the recording mechanism detected by the abnormality detecting means 120C is preferably recorded in the storage means 127 on the main body side together with the real time data. When the cartridge is ejected, this record is written to the cartridge side storage means before the cartridge is ejected, so checking this record shows the reliability of the analog recording.

According to another aspect of the present invention, there is provided a recording medium mounting apparatus, the apparatus comprising a recording medium mounting apparatus for use in a main body on which the chart paper is detachably mounted. A recording mechanism is provided for mechanically recording vehicle information on the chart paper while the chart paper is rotated by a clock mechanism, and the recording medium mounting apparatus includes a chart paper accommodating portion for detachably receiving the chart paper; It is comprised by the cartridge side storage means which is accommodated in the recording medium mounting apparatus adjacent to this chart paper storage part, and electrically records the vehicle information corresponding to the recording performed by the recording mechanism 18C mechanically with respect to the chart paper.

The vehicle information corresponding to the recording mechanically performed by the recording mechanism on the chart paper is mechanically recorded in the cartridge side storage means 160 located adjacent to the chart paper receiving portion of the recording medium mounting apparatus, and the chart paper having the analog recording. And the storage means 160 having the digital record can be handled as a single unit.

The recording medium mounting apparatus includes processing means 163 for processing the vehicle information on the main body side and then recording it to the cartridge side recording means. Therefore, by changing the processing in the processing means, the information to be collected is not limited by the main body and can be determined relatively freely.

The above and other objects, features and advantages of the present invention will become apparent from the following description and claims taken in conjunction with the accompanying drawings.

A cover 43 is provided on an upper surface of the box-shaped body 41, which is rotatably installed through a hinge 41a provided on an opposite surface of the box-shaped body. As shown in FIG. 3B, the cover 43 is rotatable to open generally at right angles to the surface of the box-shaped body 41.

A handle 43a is formed on the cover 43, and the cover 43 is opened by pulling it by hand.

As shown in FIG. 3D, a battery exchange lead 40a is provided on the bottom of the box-shaped body.

The cover 43 is opened, and the chart paper 50 is set on the shaft 42 at the center portion. The opening 41b is provided on the upper surface of the box-shaped body 41 so that a part of the set chart paper 50 is exposed.

On the front left side of the box-shaped body 41, a gear 44 is arranged in a protruding state, which is connected to the shaft 42 via a gear train inside the box-shaped body 41. When the shaft 42 is rotated by rotating the gear 44 by hand, the present time of the chart paper 50 set on the shaft 42 can be set. As shown in FIG. 3D, grooves 41C are formed on the left and right sides of the bottom surface of the box-shaped body 41, and a movable piece 45 extends in one of the grooves 41C.

When the movable piece 45 is inserted into the associated groove, the shutter 46 of FIG. 3C to be interlocked opens in the direction of the arrow to expose the built-in gear. After the cartridge 40 is mounted to the main body 1, the movable piece 45 is inserted, and at this time, the shutter 46 is opened so that the internal gear is connected to the clock mechanism in the main body 1.

Now, the internal structure of the main body 1 of the driving recorder will be described. 4 is a side view of the main body 1, in which the cover covering the top and side surfaces of the main body 1 and the recording mechanism for recording vehicle information on the chart paper is omitted, and the cartridge 40 is not mounted. .

As shown therein, the substrate 90 is embedded in the main body 1, which is supported and fixed by the front panel 2 and the bottom plate 8. Under this substrate 90, a first chassis 60, a second chassis 70, and a third chassis 80 are arranged in this order.

The first chassis 60 is made of a metal plate, as shown in FIG. 5, a U-shaped recess is formed in the center portion, and slits 61 are formed on the front left and right sides. In addition, a hole 62 in the form of a keyhole is formed on the left and right sides of the rear surface of the first chassis 60. The first chassis 60 is attached to the substrate (not shown) via the bolt 63 by using the slit 61 and the hole 62.

One side of the spring 64 is provided on the left and right sides of the center of the first chassis 60, and the other side thereof is provided on a substrate (not shown), so that the first chassis 60 faces the front side, that is, the front panel ( 2) is pressed to the side. On one side of the first chassis, as shown in FIG. 4, a fin 65 extending laterally is provided, which is supported by the arm 101 of the retaining mechanism 100 fixed to the substrate 90. Will be maintained.

The holding mechanism 100 is comprised from the fixing | fixed part 102 and the substantially V-shaped arm 101 supported rotatably on the shaft 103 of this fixing | fixed part 102. As shown in FIG. The fixing part 102 is fixed to the substrate 90, and the arm 101 rotates about the axis 103 in the upward direction as indicated by the arrow when pressed. A portion of the arm 101 has a hole 104 formed therein.

Since the pin 65 is held by the arm 101 of the retaining mechanism 9100, the first chassis 60 remains in the rear position even when the pin 65 is pushed forward. This state occurs when the ejector button 6 is pressed to eject the cartridge 40 mounted therein. In the step before pressing the ejector button 6, the cartridge is mounted. As shown in FIG. 7, the pin 65 of the first chassis 60 is in contact with the tip of the arm 101 of the holding mechanism 100. As shown in FIG. It is a state.

As soon as the ejector button 6 is pressed, the first chassis 60 is moved rearward so that the pin 65 is supported by the arm 101.

Next, the second chassis 70 will be described. The second chassis 70 is made of an iron plate and has a substantially tray shape.

As shown in FIG. 4, the projections 71a, 71b, 71c (71c are not shown) are arranged in parallel on the side surface of the second chassis 70. As shown in FIG. The central protrusion 71b is held by the bisected fork-type regulating member 95 fixed to the substrate 90 and is restricted by the longitudinal movement of the second chassis 70.

Each side surface of the first chassis 60 is provided with two rectangular side plates 66 (only one is shown) as a locking means. Each side plate 66 is provided with a slot 67 which is inclined considerably, and the slot 71 is caught by the projection 71a of the second chassis 70. Therefore, when the ejector button 6 is pressed and the first chassis 60 is pushed backward, the longitudinal movement of the second chassis 70 is restricted by the restricting member 95, so that the projection 71a is the first chassis ( The second chassis is lowered by being guided along the slot 67 of the side plate 66 of 60. When the first chassis 60 is held rearward by the retaining mechanism 100, the lowering of the second chassis 70 is stopped.

5 is a plan view of the main body from which the substrate 90 is omitted. The two projections 72 provided at the rear end of the second chassis 70 are stoppers used when the cartridge is mounted.

The watch mechanism shown at 110 in this figure has a gear 111 that meshes with a gear in the shutter 46 of the cartridge to rotate the chart paper when the cartridge 40 is mounted.

Now, the third chassis 80 will be described. The third chassis 80 is also formed of a metal plate, and is provided in close contact with the lower side of the second chassis 70. As shown in FIG. 6, the protruding pieces 73 formed in the second chassis 70 are caught by the holes 81 of the third chassis 80 and the transverse direction and the vertical direction of the second chassis 70. Movement is regulated. One end of the spring 82 is attached to the center of the third chassis 80, and the other end of the spring 82 is provided on the second chassis 70, so that the third chassis 80 is forward, that is, It is pressed in the direction of the front panel 2. Cartridge locking pins 83 are provided at left and right centers of the third chassis 80, respectively, and the cartridge locking pins 83 are erected vertically upward. A projection 84 is formed on one side of the third chassis 80, and a locking projection 85 is applied to the holding mechanism 100 in the upward direction at the tip of the projection 84.

In FIG. 6, the second chassis 70 is actually visible, but is represented by an imaginary line to prevent confusion.

When the cartridge 40 is inserted through the cartridge detachment opening 7 (FIG. 2) of the front panel 2, the end face of the groove 41C on the rear surface of the cartridge 40 is inserted into the cartridge locking pin 83. When the cartridge 40 is inserted, the third chassis 80 moves rearward against the pressing force of the spring 82.

At this time, the locking projection 85 of the third chassis 80 is inserted into the hole 104 of the arm 101 of the holding mechanism 100 held by the first chassis 60 in the rear position, and thus the arm ( Rotate against the pressing force of 101).

Thus, as shown in FIG. 7 and the pin 65 of the first chassis 60 is separated from the arm 101, the first chassis 60 is moved forward so that the pin 65 of the arm 101 is moved. It comes in contact with the tip.

Since the projection 71a provided on the side of the second chassis 70 is coupled to the slot 67 of the side plate 66 of the first chassis 60, when the first chassis 60 moves forward, the projection ( 71a) is guided along the slot 67 so that the second chassis 70 moves upward. Since the projection 71b of the side center part of the 2nd chassis 70 is hold | maintained between the restricting members 95 provided in the board | substrate 90, the 2nd chassis 70 cannot move back and forth.

When the second chassis 70 is raised, the cartridge 40 is also integrally raised, and the chart paper 50 stored in the cartridge 40 is in contact with the recording needle of the recording mechanism described later in the main body 1. Is set in position. The chart paper 50 is exposed through the opening 41b of the case 41 of the cartridge 40, and the recording needle of the recording mechanism is connected to the opening (not shown) of the substrate 90 and the first chassis 60. The chart paper 50 is brought into contact with the U-shaped recess. 8 and 9 are a plan view and a bottom view, respectively, in a state where the cartridge 40 is mounted, and FIG. 7 is a side view.

In this case, the board | substrate 90, the bottom plate 8, and the cartridge 40 are abbreviate | omitted. As described above, when the cartridge 40 is raised, the cartridge 40 is exposed to the electrode 161a of the connector 161 on the upper surface of the cartridge 40 to come into contact with an electrode (not shown) provided in the main body 1. .

Now, the recording mechanism will be described. FIG. 10 shows an example of the recording mechanism. In this figure, 11 represents a motor, and the gear 12 is provided in the shaft 11a. 13 is a gear train for transmitting the power of the gear 12, 14 is a directional gear gear meshed with the final gear of the gear train (13). 15A and 15B are drive gears meshed with the direction change gear 14, and rotate the recording set down cams 16A and 16B, respectively. 17A and 17B are L-shaped vibration bars vibrating about the point 0 by the recording needle lifting cam 16A, and 17C are L-shapes vibrating about the point 0 by the recording needle lifting cam 16B. It is a vibration bar. 18A, 18B, and 18C represent recording needles descending (upward in FIG. 10) by corresponding vibration bars 17A, 17B, and 17C.

Each of the recording needles 18A, 18B, and 18C is caught by the engaging pieces 19A, 19B, and 19C in the center portion, and is supported on the frame bodies 20A, 20B, and 20C. The coil springs 30A, 30B and 30C are installed between the engaging pieces 19A, 19B and 19C and the frame bodies 20A, 20B and 20C to lower the recording needles 18A, 18B and 18C. In the upward direction).

The projections 17Aa, 17Bb, 17Cc of the vibrating rods 17A, 17B, 17C are located on the upper surface of the engaging pieces 19A, 19B, 19C and pressurized upward by the coil springs 30A, 30B, 30C. Accordingly, the ends of the vibrating rods 17A, 17B, and 17C come into contact with the surfaces of the recording needle lifting cams 16A and 18B.

The recording needle 18A is for distance recording, the recording needle 18B is for alternating recording, and the recording needle 18C is for speed recording. Since the recording needle drive mechanism for moving these recording needles 18A, 18B, and 18C in the radial direction of the recording paper C is the same as the conventional one, description thereof is omitted.

In the state where the recording needles 18A, 18B, and 18C are in the ascending position, the motor 11 is controlled based on the output of the lock detection mechanism (not shown) that detects the mounting of the cartridge 40 so that the recording needle lifting cam 16A 16B) rotates approximately 180 degrees. Therefore, since the vibrating rods 17A, 17B, and 17C rotate and the projections 17Aa, 17Bb, and 17Cc are lowered, the recording needles 18A, 18B, and 18C are driven by the pressing force of the coil springs 30A, 30B, and 30C. It descends (in the upward direction in the drawing) and comes into contact with the chart paper 50 surface. Therefore, various types of information can be recorded on the recording paper C with the recording needles 18A, 18B, and 18C.

The cartridge 40 is mounted, and the recording needles 18A, 18B, and 18C are in contact with the surface of the chart paper 50, and the key is inserted into the lock 4 of the main body 1 in the clockwise direction. When rotated, the motor 11 is controlled based on the output of the lock detecting mechanism that detects that the cartridge 40 is unlocked.

As a result, the recording needle elevating cams 16A and 16B are further rotated about 180 degrees to return to their original positions. Accordingly, the recording needles 18A, 18B, and 18C that are lowered by the pressing force of the coil springs 30A, 30B, and 30C are vibrating rods 17A, 17B, and 17C against the pressing force of the coil springs 30A, 30B, and 30C. It rises by the rotation of and moves away from the recording surface of the chart paper 50. Next, when the ejector button 6 is pressed, as shown in FIG. 4, the first chassis 60 is pressed so that the side pin 65 is held by the holding mechanism 100, at which time the arm of the holding mechanism 100 is held. The locking protrusion 85 of the third chassis 80 is separated by the rotation of the 101, and the third chassis 80 is advanced to move the cartridge 40 to the outside through the cartridge detachment outlet 7. Will be pressed. Subsequently, the cartridge 40 is taken out by hand, the necessary chart paper 50 is set, time setting and the like are performed. Incidentally, the above-described recording needle raising and lowering mechanism and recording mechanism are one example, and other configurations capable of performing the same function are also available. Therefore, when the chart recorder 50 supplies the chart paper 50 to the cartridge, the operator can perform the exchange of the chart paper 50 or the time setting of the chart paper 50 by hand.

Stepping motor drivers 121 to 124 are connected to the CPU 120. The stepping motor driver 121 is for driving the traveling speed recording needle 18C. The CPU 120 outputs to the stepping motor driver 121 the number of driving pulses necessary to move the traveling speed recording needle 18C to a position corresponding to the measured traveling speed, and the stepping motor driver 121 is stepping. The motor 121A is driven to rotate this output shaft by an angle corresponding to the number of drive pulses.

The rotation of this output shaft is transmitted via the gear train 121f to the pinion 121e engaged with the rack 121D formed on the moving plate 121C for transporting the traveling speed recording needle 18C. Therefore, the recording needle 18C reciprocates in the direction of the arrow in accordance with the forward and reverse rotation of the stepping motor 121a, and the movement amount of the recording needle 18 changes depending on the vehicle driving speed.

The encoder 121a which rotates with the rotation of the pinion 121e is provided, and this encoder 12a codes the position of the recording needle 18C, and inputs a position code into CPU120.

In the PROM 127 serving as a nonvolatile storage means, as shown in FIG. 12, the types of the recording needles vary depending on the vehicle number of the vehicle on which the driving recorder is mounted and the type of the chart, for example, shift recording or status recording. The setting data area 127a is formed in which setting data such as a set value of the maximum running speed of the vehicle or the like is stored. This setting data is input and written from the outside through the I / F circuit 128 by a setting device (not shown).

In addition, the distance data area 127b is formed in the PROM 127, and the updated travel distance data is stored as the vehicle travels. In the PROM 127, a collection data area 127C is formed in which an abnormal state of the speed, distance, and clock driving system is stored together with the time data generated by the calendar clock 126.

And a RAM 163b having a data area in which various kinds of data are stored, and a microcomputer (CPU) 163 operating according to a control program in a predetermined ROM 163a is provided. The CPU 163 is connected to the I / F circuit 128 of the main body 1 via the interface (I / F) circuit 165 to exchange data with the CPU 120 of the main body 1. The CPU 163 is connected to an opening / closing detection switch 166 which is turned on and off as the lid 43 on the upper surface of the cartridge 40 is opened and closed for attachment and detachment of the chart paper 50. The on / off of this open / close detection switch 166 is recorded in the data memory 160. 167 denotes a battery for power supply, which can be omitted when power is supplied from the main body 1.

In the data memory (PROM () 160) as the nonvolatile storage means in the cartridge 40, as shown in FIG. 13, the first, second and third collection data areas 160a, 160b and 160c. ) Is formed. The first collection data area 160a receives and stores the setting data stored in the PROM 127 on the main body 1 side when the cartridge 40 is mounted on the main body 1.

The second collection data area 160b stores data continuously generated at the main body 1 side through the I / F circuit 165 and the CPU 163 when the cartridge 40 is mounted to the main body 1. The data is selected and processed according to the program by the CPU 163 and stored therein. The third collecting data area 160C stores the main body (when the cartridge 40 is ejected from the main body 1). 1) The collection data stored in the PROM 127 on the side is received and stored.

The operation of the analog digital navigation system having the electric circuit configuration of FIG. 11 will now be described. The CPU 120 in the main body 1 starts the operation by turning on the power, and starts the recording operation of the speed, the distance, and the shift information when the cartridge is set at the predetermined position.

First, the speed recording operation will be described. When the stopped vehicle starts to travel, the travel pulse generated by the travel sensor S is input to the CPU 120. The CPU 120 measures the period of the traveling pulse and calculates the vehicle traveling speed based on the measured period.

Therefore, the number of steps necessary for the stepping motor 121a to move the traveling speed recording needle 18C at the position of 0 km / h to the value corresponding to the speed obtained by this calculation is determined based on the ROM ( Obtained by the table provided in 120a) or by a predetermined calculation formula.

The number of steps thus obtained is compared with the present value of the up-down counter area formed in the RAM 120b indicating the number of steps corresponding to the current position of the stepping motor 121a, and the absolute value of the difference therebetween is obtained. The CPU 120 outputs the number of driving pulses corresponding to the absolute value to rotate the stepping motor 121a forward when the present value is smaller and reverse rotation when the present value is larger, and simultaneously the up-down in the RAM 120b. The counter counts up and down according to the output of the drive pulse. For this reason, while the traveling speed recording needle moves to the calculated traveling speed position, the number of steps indicating the current position of the stepping motor 121a viewed from the CPU 120 side is maintained in the up-down counter.

The encoder 121g indicates that the recording needle 18C is in one of a plurality of division ranges, thereby generating a position code indicating the position of the traveling speed recording needle 18C moving as the stepping motor 121a rotates. do. This position code is input to the CPU 120. The CPU 120 converts the received position code into a corresponding number of steps and compares it with the value of the up-down counter in the RAM 120b. As a result of the comparison, if a predetermined difference exists between them under predetermined conditions, the contents of the up-down counter are rewritten in the number of steps corresponding to the position code indicating the position of the actual speed recording needle 18C, and the value indicating the current position is updated. .

The updated step number is the actual value of the traveling speed record needle 18C, and is updated through the I / F circuit 128 with real time data each time it is updated, and the I / F circuit 165 of the cartridge 40 is removed. Is input to the CPU 163. The CPU 163 has this input step number stored in the second collection data area 160b of the PROM 160, so that digital data corresponding to the traveling speed recorded on the chart is collected.

The position correction by updating the above-mentioned step number arises from some kind of abnormality. When the number of corrections performed is checked, if the number of corrections exceeds a predetermined number, it is determined that there is an abnormality, and the occurrence of the abnormality is stored in the collection data area 127C in the PROM 127 together with real time data indicating the occurrence time. This abnormality determination method includes a first method for determining whether the upper limit of the number of times has been exceeded, a second method using the mileage correction number, a third method using the number of corrections per unit time (for example, one hour) and the total number of corrections, and each predetermined A fourth method is used that uses the number of intervals between two corrections that are shorter than the limit of.

The operation of the CPU 120 described above is shown in FIG. 14 as a functional block diagram. The period measuring unit 120-1 measures the period of the driving pulse from the driving sensor S, and the driving speed calculating unit 120-2 is based on the period measured by the period measuring unit 120-1. The driving speed is calculated, the traveling speed step part converting unit 120-3 obtains the number of steps corresponding to the speed calculated by the traveling speed calculating unit 120-2, and the difference determining unit 120-5 is the traveling speed. The difference between the number of steps from the step number converting unit 120-3 and the count value of the up-down counter 120-4 is determined, and the driving pulses of the number corresponding to the difference are output together with the signal indicating the magnitude. do. By the driving pulse from the differential judging unit 120-5, the stepping motor driver 121 rotates the stepping motor 121a forward and backward with the number of steps corresponding to the driving pulse.

The driving pulse output by the difference judging unit 120-5 is applied to the up-down counter 120-4, and the driving pulse is up or down counted according to the signal indicating the magnitude, so that the number of steps of the stepping motor is an up-down counter. It can be seen from the count value of (120-4). The driving pulse corresponding to the difference between the current step number of the stepping motor seen from the driving side and the step number corresponding to the calculated traveling speed is supplied to the stepping motor driver 121 to drive the stepping motor to cope with the traveling speed. The speed recording needle 18C can be driven at a position to

In this case, however, it is not guaranteed that the speed recording needle 18C moves to a position corresponding to the actually calculated traveling speed. Therefore, the encoder 121g generates a position code corresponding to the position of the speed recording needle 18C, converts this position code into the number of steps in the position step number converting unit 120-6, and converts this number of steps. And the number of steps corresponding to the calculated traveling speed are compared in the comparator 120-7. If the number of steps does not match with each other under predetermined conditions, the contents of the up-down counter 120-4 are replaced with the number of steps converted by the position step number converting unit 120-6 indicating the actual position of the speed recording needle 18C. It updates and matches the position of a stepping motor of a drive side with an actual position.

The updated step number is sent to the cartridge 40 and stored together with real-time data from a calendar or clock not shown as it is or after processing in the second collection data area 160b of the PROM 160. As a result, digital data corresponding to the traveling speed recorded on the chart sheet can be collected.

On the basis of the update of the number of steps, the abnormality determination unit 120-8 determines whether or not an abnormality has occurred under the predetermined determination condition, and if it is determined to be abnormal, together with real-time data in the collection data area 127C of the PROM 127 The abnormality is stored. The data of this collected data area is read out at the time of ejection of the cartridge, sent out to the cartridge, and stored in the third collection data area 160C in the PROM 160.

The distance recording operation will now be described. When the vehicle starts to travel, the travel pulse generated by the travel sensor S is input to the CPU 120. The CPU 120 counts the number and performs an operation based on this count value. When the count value reaches a predetermined value, the CPU 120 generates a distance signal to indicate that the vehicle has traveled a unit distance, for example, 100 m. By the distance signal, the content of the distance data area 127b of the PROM 127 increases, and the distance indicator indicates the distance based on the content of the distance data area 127b.

In addition, when the count value of the traveling pulse reaches a predetermined value, the CPU 120 generates a driving pulse to the stepping motor driver 122 that drives the stepping motor for moving the distance recording needle, and an integrated odometer not shown. The cartridge 40 is supplied to the stepping motor which drives the stepping motor which rotates the counter, respectively.

The CPU 163 in the cartridge 40 independently processes the drive pulses supplied to the cartridge 40, and collects distance data based on this.

When outputting the drive pulse, the CPU 120 determines whether or not the stepping motor driven by the drive pulse is operating or not. For this purpose, a photointerrupter interlocked with the stepping motor which is rotated by the drive pulse is provided, and the number of rotation pulses generated by this photointerrupter and the number of drive pulses are compared to determine whether there is an abnormality.

If it is determined that an abnormality has occurred, the abnormality is stored in the collection data area 127C together with the real-time data, and this data is extracted to the cartridge at the time of discharge of the cartridge and stored in the third collection data area in the cartridge.

The above-described distance recording operation of the CPU 120 is shown in the functional block diagram in FIG. The pulse number counting unit 120-11 calculates the number of driving pulses from the traveling sensor S to generate driving pulses. The distance data area 127b is increased by the distance calculating part 120-12 calculating a distance based on the count value of this pulse number counting part 120-11, and outputting a distance signal for every predetermined distance.

The contents of this distance data area 127b are used to display the distance on the distance indicator, and are sent out to the cartridge 40 when the cartridge is discharged and stored in the third collection area 160C.

The driving pulse generated by the pulse counting unit 120-11 is supplied to the abnormality determining unit 120-13, where it is compared with the operation state signal input from the stepping motor, Rotational abnormality is determined. If it is determined that the abnormality has occurred in the abnormality determining unit 129-13, it is stored in the collection data area 160C together with the real time data from the calendar clock 126.

Now, the clock driving operation of rotating the chart paper will be described. The CPU 120 counts the ticks of the calendar clock 126 and generates a driving pulse for each count of a predetermined value, and supplies this to the stepping motor driver 124 which drives the stepping motor for rotating the chart paper. .

The CPU 120 determines whether or not the stepping motor driven by the drive pulse at the time of outputting this drive pulse is operated to determine whether there is an abnormality. For this purpose, a photointerrupter interlocked with the stepping motor rotated by the drive pulse is provided, and the presence or absence of abnormality is determined by comparing the number of rotation pulses generated by this phono interrupter with the number of drive pulses. If it is determined that an abnormality has occurred, it is stored in the collection data area 127C together with the real time data, and this data can be sent to the cartridge at the time of discharge of the cartridge and stored in the third collection data area in the cartridge.

16 is a functional block diagram showing the clock driving operation described above. The pulse number counter 120-15 counts clock pulses from the calendar clock 126 to generate driving pulses. The pulse counting unit 120-15 supplies the driving pulse generated by the stepping motor driver 124 to drive the stepping motor for rotating the chart paper. When the drive pulse is outputted, in order to determine whether there is an abnormality in the operation of the driven stepping motor, a photointerrupter interlocked with the stepping motor which performs the rotation operation by the drive pulse is provided. The abnormality determination unit 120-16 compares the number of rotation pulses and the number of driving pulses generated by this photo interrupter to determine whether there is an abnormality. If it is determined that an abnormality has occurred, it is stored together with real-time data from the calendar clock 126 in the collection data area 160C, and the stored data is stored in the third collection data area 160C in the cartridge when the cartridge is discharged. Save it.

As described above, the counter recognizes the step position of the stepping motor by the up-down count of the driving pulse which drives the stepping motor to the position of the step number corresponding to the traveling speed. If the contents of the counter differ from the position of the stepping motor actually driven, the contents of the counter are replaced with the number of steps corresponding to the position code generated by the encoder interlocking with the stepping motor under a predetermined condition, and the cartridge is updated. 40 is stored in the data memory 160.

Therefore, the traveling speed data corresponding to the recording by the actual traveling speed recording needle can be collected. By collecting this speed data in association with the time data, it can be used as a reference when reading the record of the traveling speed on the chart paper. The frequency at the time of update occurrence can also be known.

Since the CPUs are built in the main body 1 and the cartridge 40 independently of each other, the functions of the CPU on the cartridge 40 side can be changed in various ways without changing the functions of the main body 1. In response, various types of digital data can be collected. By integrating the cartridge 40 in which the chart paper is stored and the data memory 160, transportation after recording becomes convenient.

In addition, it is possible to ensure the integration of analog recording and digital recording. In particular, by recording each time the lid is opened as in the above-described embodiment, it is possible to ensure that the contents of the chart paper are the same as the digital recording contents, unless there is a record indicating that the lid is opened.
