The following describes the operation of this embodiment configured as described above.

5 is a general flowchart showing an outline of the operation of this embodiment. That is, in general, when step S1 is in the standby state and there is a time signal in the frequency divider circuit 20 of FIG. 3, the step processing is performed so that the time of the time register T to store the current time is as large as the unit time. performs when run on (S _2), and had a signal (S _a) in the other key input signal or a waveform shaping circuit 25, a predetermined key process corresponding to it in the step (S _3). After the time-processing or key processing is finished in the next step S ₄ , data according to the mode indicated by the registers M, B, D, C, and F is displayed on the liquid crystal display panel 2. The process then returns to the standby state of the bogie step S ₁ .

6 and 7 are detailed flowcharts of the key processing of the step S3, except for the processing of the switch SW ₁ , the matrice mode (register M) = [2] and the width mode M = [3]. The key processing in is shown in detail. That is, the key processing in the time display mode M = [0] and the measurement mode M = [1] is omitted. 8-10, 12, 15, and 16 are transition display diagrams of the display of the liquid crystal display panel 2 based on the operation of various keys, and 11, 14, and 15 are memories of the display data storage unit RM. It indicates the memory state of. Hereinafter, the operation of this embodiment will be described with reference to the above drawings.

(a) Operation in the time display mode and the measurement mode For example, when [0] is set in the mode register M now, and the time display mode is specified, the register T is displayed in the liquid crystal display panel 2. The current time data of is displayed, for example, 10:58:90 seconds Wednesday, December 27, 1987, as shown in A of FIG.

In this case, when the switch SW ₁ is operated, the key processing of step S ₃ in step S _{1 of} FIG. 5 is advanced, that is, the flowchart of FIG. 6 is moved, and the switch SW ₁ in step S ₁₀ . detecting the operation and executes the incremental processing of +1 to a mode register (M) at the step (S _11), and its value to the measurement mode to [1]. Subsequently, the flow advances to step S ₁₂ and changes to the display in the measurement mode such as instructing the display of the character of [MSR] indicating the measurement mode on the first display unit 1a of the liquid crystal display panel 2. Do the processing for As a result, the display state becomes as shown in FIG.

In this measuring mode, the measuring wheel 3 is driven in accordance with the object, thereby enabling the measurement of the length of the object. That is, each time the measuring wheel 3 is rotated 1 mm according to the object, the signal SA is input, and the signal SA is accumulated in the register H as length data in units of 1 mm. Therefore, the length data obtained by the rotation of the measuring wheel 3 is stored in the register H and displayed on the display portion 2g of the liquid crystal display panel 2.

(b) Operation in mapped mode

The switch SW ₁ is operated in the measurement mode shown in B of FIG. 8 so that the present embodiment can be used as the meter. At this time, the operation is detected in step S ₁₀ , and in step S ₁₁ , the value of the mode register M becomes [2] to enter the mapped mode. Then, the display content change processing, that is, the accumulated data of the RAM 13 specified by the memory pointer B at that time is the memory in the storage unit SR, that is, the memory E _{0 to} E ₉ . Step S ₁₂ is instructed to display the scale data stored in M ₀ on the liquid crystal display panel 2, and is displayed as shown in C of FIG. 8 by step S4 in FIG. 5.

In the muff meter mode, there are four display states: a normal state, a data input possible state, a measurement state, and a measurement result display state, which are controlled by the value of the register (C).

Thus, Fig. 9 shows the transition of the display in the normal state and the data input enabled state in the matrice mode. For example, now, when [0] is set in the status register C, it is in a normal state, the memory M ₀ is designated by the memory pointer B, and the scale is 1 / 250,000 and the scale stored in the memory. It is assumed that is shown in the third display section 2c and the sixth display section 2h, respectively, as shown in A of FIG. Here, in order to select the other scale data stored in the other memory in accordance with the map to be used at this time, the switch SW ₂ is operated until the desired scale data is displayed while the display of the liquid crystal display panel 2 is displayed. At this time, the operation of the switch SW ₂ is detected in step S ₁₅ of FIG. 6, and it is determined in step S ₁₆ that the matrice mode (register M = [2]) is performed. In step S ₁₇ , the normal state (register C = it is determined to be in the [0]), get along a scale, select processing that specifies the sequence of the next memory by being a +1 increment processing for the memory pointer B executed in the next step S _18. That is, when the designated memory E _0, and when the switch SW ₂ operation on specified selection new memory E _1, when the switch SW ₂ operation when the specified memory E ₁ in a state where the memory E ₂ that specifies selection Proceed with the designation. And it is selected in the display process of a fifth-degree step S _4. Data stored in the memory is displayed on the liquid crystal display channel 2 as in B to D of the drawing. Further, in FIGS. 9A to 9, the right side of the first display portion 2a is [0], [1],... And [9] indicate each memory number of the scale data storage unit SR in which the displayed scale data is stored.

For example, when the scale data of the map to be used this time is not stored in any memory of the scale data storage unit SR, the scale data of the memory in which arbitrary scale data is stored is corrected, and the scale data of the map used for the current company is corrected. In this case, first, operate the switch SW ₂ in the normal state to designate a memory in which arbitrary scale data is stored, and display the scale data on the liquid crystal display panel 2 and switch SW thereon. ₃ is operated to set the scale data input function shown in E, F, and G of FIG. That is, the operation of the switch SW ₃ is detected in FIG. 6, step S ₄₀ , and it is determined in step S ₄₁ that it is in the matrice mode of the register M = [2], and the register C = [0 in the next step S ₄₂ . ] Is judged to be in the normal state, and [1] is set in the state register C in the next step S ₄₃ to make the scale data input possible. Then the in step S ₄₄ to set the destination to the instruction to display the flash unit that is displayed at that point. For example, as shown in B of FIG. 9, when the switch SW3 is operated while the contents of the memory E ₁ , that is, the scale is one hundredths of a thousandth, and the unit data [km] are displayed, as shown in E of FIG. As such, the unit data [km] is displayed flickering. If the switch SW4 is operated in this state, the unit data will be selected sequentially, although details will be described later.

Then, transfer to the new input of the scale data, but this is operated by the switch SW ₂ as shown in F, G of FIG. They are assigned sequentially in the order of the lowest positions and corrected by the switches SW ₄ . First, the operation in the case of specifying the input target in the above-described sequence while operating SW ₂ will be described. At this time, the operation of the switch SW ₂ is detected in step S ₁₅ of FIG. 16, and it is determined in the next step S ₁₆ that it is in the mmeter mode, and it is determined in step S ₁₇ , S ₁₉ that it is not a normal state but a scale data input state. At the same time it pushed out of the designation of one at the input destination to the step S ₂₀ to a display process for displaying a flash that a new input object each time.

After again specify the target type as described above, the operation goes to the W dwichi SW ₄ each time to the correct target type. The switch operation of the SW ₄ at this time is detected in the seventh degree step S ₆₅ it is determined that called maepeu meter mode in the next step S ₆₆ of, again, the next step S _67, S _70, is possible in S ₇₃ the scale data input of the state (Register C = [1]) is determined, and in the next step S ₇₄ , new unit data is selected if data to be input, for example, unit data, and numerical values are changed if scale data. And the fifth-degree step S ₄ the changed data is displayed on the liquid crystal display panel (2).

After the above-described manner, type units data and scaling data in conformity with the map used for the measurement, and again operates the switch SW _3, as shown in the FIG. 9 for enabling, based on them can be a measurement returned to the normal state do. The art operation is detected in the step (S _40), it is judged that the maepeu meter mode in step S _41, determining that the next step S _42, is possible in S ₄₅ the scale data input, and the above condition in step S ₄₆ [0] is set in register C to return the normal state. In step _S47 , the unit data and the scale data newly input as the above processing are stored in the memory designated by the memory pointer B (that is, the new scale data is recorded and replaced). And the fifth-degree step S ₄ displays them on the liquid crystal display panel (2).

10 shows the transition of the display of the liquid crystal display panel 2 in the normal state, the measurement state, and the measurement result display state in the matrice mode. As described above, for example, in the case where the keyometer is set as the scale of 50000 and the unit of the measurement distance, the liquid crystal display panel 2 displays as shown in Fig. 10A.

Subsequently, the measurement state is set to start measurement, but in this case, the switch SW ₄ is operated as shown in FIG. At this time detects the art operate in the seventh degree Step S _65, determining that the next step S ₆₆ the determines that one maepeu meter mode, the in step S ₆₇ to the normal state, and the state in the next step S ₆₈ of the register C Set 2 to the measurement state. In the next step S ₆₉ , the first display unit 2a causes the first display unit 2a to display the memory number of the memory of the navigation data storage unit RM designated by the memory pointer D, in the process of instructing the blinking display of the measurement state mark display member 2i. The measurement possible state display processing such as the processing and the processing of lighting the LED 23 of FIG. 3 is performed. As a result, the display of the liquid crystal display panel 2 is as shown in FIG. In addition, the display which becomes M1 of the 1st display part 2a of the same figure shows that the memory G1 is specified by the memory pointer D. As shown in FIG.

After the above preparation, the measurement wheel 3 is driven in connection with the path under measurement between the two points on the map, but at this time, the signal SA is output from the waveform shaping circuit 25 of FIG. 3 whenever the transmission becomes a certain length. Whenever there is such an output, the process proceeds to step S ₈₇ after passing through the snaps S ₈₅ and S _{86 shown} in FIG. 7, the contents of the register H are added, and the length data is stored in the register H, Based on the transmission distance data and the scale data, the actual distance corresponding to the transmission distance is obtained by calculation, and the distance measurement processing is performed sequentially to the value of the measurement register N. And a fifth step S ₄ degrees in the measurement result up to that point, that is going to indicate the value of the transmission distance and the measurement data register (N) to the fifth display section (2g) of the liquid crystal display panel (2). For example, when the length of the map on which the measurement target is measured at 1 / 500,000 is 86 mm, the actual distance is 4.30 km, and when the measurement is completed, the display is displayed on the liquid crystal display panel 2 as shown in FIG.

After the measurement is completed as described above, as shown in FIG. 10, the switch SW ₂ is operated to clear the result of the present measurement, and the switch SW ₄ is operated to prepare for re-measurement or to terminate the measurement operation. To display the measurement results.

In this case, when the switch SW ₂ is operated in order to clear the current measurement result and prepare for re-measurement, the operation is detected in step S ₁₅ , and step S ₁₆ is passed through steps S ₁₆ , S ₁₇ , S ₁₉ , and S ₂₁ . _When it reaches ₂₂ , processing such as clearing the current measurement result stored in the register H and the measurement register N is executed, and the display returns to the state of B in FIG. When the switch SW ₄ is operated to end one-measurement operation and continue the display of the present measurement result, the operation of the switch SW ₄ is detected in step S ₆₅ of FIG. 7 and passes through steps S ₆₅ , S ₆₇ , and S ₇₀ . in the step S ₇₁ thereby indicating the stop of the blink of the display by measuring the wheel 3 is rotated executed also with the measurement condition mark display body (21) with a measurement stop process of the counting operation does not LED23 off. As a result, the display of the liquid crystal display panel 2 becomes as shown in FIG.

After the measurement result is displayed as described above, the length of the path measured this time corresponds to the memory of the display data storage unit RM of the RAM 13 (in this case, the memory number G ₁ displayed on the first display unit 2a). Memory G ₁ ) to return to the normal state by operating the switch SW ₂ (see FIG. 10). Operation of the switch SW ₂ at this time is detected in step S ₁₅ is determined in the step S ₁₆ to be maepeu meter mode, again the determination of what is not a normal state, scale data input state, the measurement state step S _17, S ₁₉ , in S _22, and advanced to the step S _23. And a step S ₂₃ the judgment that it is stored is a current time measurement data to the measurement register N, and continue to be designated by the memory pointer to D in step S ₂₄ the memory (in this case, which is displayed on the first display portion (2a) that memory number M distance storing area LA and a unit storage area and each of the distance to the UA data [4.30] and a storage by transferring the unit data [5] of the km unit in the distance data in the memory is a G ₁₎ corresponding to the ₁ Let's do it. And in the next step S ₂₅ the left by 10 002 to increase the value of the memory pointer D ready for the next measurement, and clears the measurement data of the current time stored in the measurement register N in step S _26, the state again in step S ₂₇ 0 is set in register C to return to the normal state. Therefore, the display of the liquid crystal display panel 2 becomes a display which designates the next memory G ₂ as shown in FIG.

Further, in the measurement state, when the measurement data is not stored in the measurement register N without performing the measurement operation or cleared by the operation of the switch SW ₂ , the switch SW ₄ is operated to terminate the measurement operation. When switch SW ₂ is operated, step S ₂₃ is reached via steps S ₁₅ , S ₁₆ , S ₁₇ , and S ₂₁ as in the above case, but it is determined that measurement data is not stored in measurement register N. The flow advances to step _S27 to return to the normal state. Therefore, as shown by the broken line in FIG. 10, the display of the liquid crystal display panel 2 is as designated by the memory G ₁ as shown in FIG.

After the measurement for the path of 4.30 km was completed as described above, the measurement was continued for two paths, and when their lengths were respectively 10.70 km and 3.30 miles, they were also displayed in the sequential display data storage unit RM. As stored, the storage state of the display data storage unit RM is as shown in FIG.

(c) Operation in display mode

When the distance is measured in the above-described mapped meter mode in order to plan the driver and the like, and the vehicle has traveled at a certain speed to travel the distance stored in the memory in the display data storage unit RAM of the RAM 13 for a predetermined time. in the width mode to know that there can travel a few hours to operate the switch SW ₁ is in the above-described maepeu meter mode, as illustrated in FIG. 8.

In this case, the above operation is detected in step S ₁₀ , and the value of the mode register M is set to 2 to 3 in step S ₁₁ to display mode, and the display of the liquid crystal display panel 2 is changed to display mode in step S ₁₂ . the instruction to change, and continues to advance to the step S _4, and 5 degrees, and the display based on the instruction.

FIG. 12 shows the transition of the display of the liquid crystal display panel 2 in the width mode, and is now in a state in which (0) is set in the state register F. FIG. In this state, when the switch SW ₂ is operated, the distance data and the unit data stored in each memory of the display data storage unit RM of the RMA 13 are sequentially displayed as shown in Figs. It is displayed with the memory number. That is, each time the switch SW ₂ is operated, it is detected at step S ₁₅ , the step S ₃₂ is reached via steps S ₁₆ , S ₃₀ , and S ₃₁ , and the memory pointer D is set to be as large as 1 to keep this memory. A process of displaying the storage data of each memory of the display data storage unit RM addressed by the pointer D on the liquid crystal display panel 2.

Next, any one of the memories in the display data storage unit RM is selected as a driving target, and the required time for driving the distance at a predetermined speed or vice versa can be obtained. In this case, the predetermined time or predetermined speed is set. For example, when memory G ₂ having a distance of 10.70 km is stored as an object of driving or the like is shown in A, B, and C of FIG. As described above, first, the memory G ₂ is designated by the operation of the switch SW ₂ to display the distance and the unit data of the path on the liquid crystal display panel 2. Operate switch SW ₃ on it. Operation of the switch SW ₃ is detected in step S _40, step S _41, S _50, and S ₅₁ via the set 1 in the status register F in step S ₅₂ is set to the state of the.

Then, in step S ₅₃ , the time display body 2f is turned on on the fourth display portion 2d, and the tenth digit of the time in the time to be displayed as the predetermined time on the third display portion 2c is selected, and the corresponding A display similar to that of the twelfth D is performed by performing a process of blinking the display in place to display the selection.

Or more digits, after a set state before the setting of the time or speed, but this operates the switch SW ₂ of the top of the time as described (in place of the 10:00 position) ... , Bottom of time, top of speed,… The desired value is set by the rotation of the measuring wheel (3) at the designated position while the seat selection is made in the order of the uppermost position of the speed. First, the switch SW ₂ will be described for selecting and selecting a setting digit to be operated. At the same time a sense of this case, the switch detects it in S _15, when the operation of the SW ₂ and, through the step _{S 16, S 30, S 31} , S 34 reaches a step S ₃₅ and, by entering the designation of the sequential position in the sequence Each time, the blinking indication of the designated position is indicated. Moreover, when the time digit is designated, the time display 2f of the fourth display portion 2d is lit and displayed, but when the time digit is transferred from the time digit designation to the digit designation of the speed, the time display 28 is replaced with the time display 28. The display which displays the unit of the speed arrange | positioned at the 2 display part 2b is lightly displayed.

In order to set the desired value at the designated position as described above, the measuring wheel 3 is rotated until the desired value is displayed while looking at the liquid crystal display panel 2. At this time, in the degree the seventh step S ₆₅ every time that the signal SA input by the rotation step S _85, S _88, the set point via the S ₈₉ to advance to the step S ₉₀ and, as the set value sequentially larger as the memory Time memory area TA or speed memory area VA is stored. In this way the fifth-degree step S ₄ the set value is displayed on the liquid crystal display panel (2).

When 30 minutes is set as the above required time as described above, the display of the liquid crystal display panel 2 is as shown in E of FIG. When setting the speed without setting the time, operate switch SW ₂ four times in succession. By this operation, as indicated by F in FIG. 12, the most significant digit of the display portion 2a is designated, and the speed can be set. When 5 km / hour is set as the speed, the display of the liquid crystal display panel 2 is as shown in FIG.

After setting the predetermined time or the predetermined speed as described above, to obtain the speed data or the required time data from these and measured distance data, etc., operate the switch SW ₃ to display the memory data display state of register F = [0]. It is done by doing.

First, a description will be given of a case where the speed is obtained from the set predetermined time and the measured path length. For example, when the switch SW ₃ is operated when 30 minutes is set as the predetermined time and the display of the liquid crystal display panel 2 is as shown in E of FIG. 12, the operation is detected in step S ₄₀ , and step S _{41 is performed.} , S _50, S _51, via an S ₅₅ it is determined that reached in step S _56, and that the memory means that the memory speed storage area VA of G ₂ is not yet stored speed data regarding the art in this path, followed by the step in S ₅₀ determines that there is gihi time data is stored, the time storage area TA of the memory and advance to the step S _60. In step S ₆₀ , the path length is set to 30 minutes based on the distance data stored in the distance storage area LA and the unit memory area UA of the memory, that is, 10.7 km and the time stored in the time memory area TA, that is, 30 minutes. A speed of driving 21.4 km / hour is calculated, the speed is stored in the speed storage area VA of the memory, and the speed is displayed on the liquid crystal display panel 2. Thus, the memory state of the memory G ₂ after the process of step S ₆₀ is executed is as shown in FIG. In addition, the speed of 21.4 km / hour, liquid crystal display calculated as described by set 0 in the status register F in step S ₆₁ in the process at the step S ₆₀ and then to a memory data display mode, shown in claim 15 is also by this It is displayed on the panel 2. Therefore, it is extremely easy for the user to know that the speed should be 21.4 km / hour for driving the route in 30 minutes.

Next, the case where the required time is obtained from the predetermined speed and the path length to be measured will be described. For example, when 5.0 km / hour is set as the predetermined speed, and the switch SW ₃ is operated when the display of the liquid crystal display panel 2 becomes equal to G in FIG. 12, the operation is detected in step S ₄₀ . Through step S ₄₁ , S ₅₀ , S ₅₁ and S ₅₅ , the process advances to step S ₅₆ , where it is determined that the speed data is stored in the speed memory area VA of the memory, ie, G ₂ , relating to the path. The flow advances to step S ₅₇ . In step S ₅₇ , the path is stored based on the path length stored in the distance storage area la and the unit memory area UA of the memory, i.e., the speed at which 10.7 km and the speed memory area VA is stored, i.e., 5.0 km / hour. The time required for walking at a speed of 5.0 km / hour was calculated for 2 hours and 8 minutes, and the time was stored in the time memory area TA of the memory, and the time was also added to the liquid crystal display panel 2 for display. Instruct them to do it. Thus, the memory state of the memory G ₂ after the process of step S ₅₇ is executed is as shown in FIG. After the above process, the process advances to step _S58 , returns [0] to the state register F, returns to the storage data display state, and the calculated time required for 2 hours and 8 minutes as shown in A of FIG. 2). This makes it very easy for the user to know that the time taken to walk this route at a speed of 5.0 km / hour is 2 hours and 8 minutes.

In addition, the state, that is, when the calculated time 2 hours 8 minutes, and operating the switch S ₄ it in the state of the 16-degree A that is displayed on the liquid crystal display panel (2) detects it in step S _65, step S _It is determined that the time calculated by reaching the step S ₇₇ via ₆₆ , S ₇₅ , and S ₇₆ is stored in the time memory area TA of the memory G ₂ , and is stored in the time memory area TA in step S ₇₈ . In step _S78 , the predetermined time is subtracted from the time stored in the storage area TA, and as a result, the start of the subtraction process for updating the memory of the time storage area TA is instructed, and [2] is set in the status register F. To set the timer status. Subsequently, when there is a time signal, the subtraction process is executed in step S ₂ of FIG. 5, and the subtraction result, that is, the remaining time is displayed in step S ₃ every time. When the remaining time is [0], the display is the same as B of FIG. Further, when the back switch SW ₄ operation in the operation as described above, and detects it in step S _65, step S _66, S _57, S _76, via the S ₈₀ reaches a step S _81, and in the step S ₈₁ The subtraction process is stopped to return to the memory data display state.

Thus, according to the present embodiment, the user measures the path length of a specific path on a map, calculates the time required when the path is run at a predetermined speed, and displays it on the liquid crystal display panel 2, while the switch SW is displayed. _In the case where the specific route is actually started to travel at the predetermined speed while the ₄ is operated, it is very easy to recognize how many hours after the driving the vehicle can always be driven.

Moreover, this invention is not limited to the said embodiment, A various deformation | transformation application is possible in the range which does not deviate from the summary of this invention.

For example, in the present embodiment, the slit was installed on the measuring wheel 3 to measure the length on the map by the LED 23 and the hot sensor 24, but the separate wheels were joined to the measuring wheel 3, One slit of the polishing heat may be provided to measure the length. In addition, the amount of rotation of the measuring wheel may be detected magnetically, for example, without using optical detection means such as an LED horn sensor. Furthermore, the amount of rotation is controlled by a mechanical switch that is turned on and off by the rotation of the measuring wheel. You may detect it. The number of memories E ₀ to E ₉ and G ₀ to G ₉ can be increased or decreased as necessary.
