For example, in a factory that processes materials such as sheets and plates, a large amount of residual material is produced. In order to reuse such residual material, small parts are cut from the residual material with an NC cutting machine or the like. In this case, it is necessary to provide the NC cutting machine with shape data representing the two-dimensional shape of the remaining material having various shapes. In such a case, the coordinate values of the vertices of each remaining material placed on the work table (surface plate) are measured, and the coordinate values of the top points of the measured remaining material are determined. It is given to the NC cutting machine as the shape data of. The NC cutting machine recognizes the shape of the remaining material placed on the work table based on the given shape data, and also shapes the fine parts to be cut out. Based on the data, cut out such fine parts from the remaining material of the recognized shape.

On the other hand, if a partition is to be laid on the floor of the building, it is necessary to mark the points for determining the laying position. In such a case, measure the distance (coordinate value) from the two edges (coordinate axes) of the floor and mark the mark (mark) at the position determined by the design drawing. Etc. are performed. In this case, the coordinate value of each point is also measured.

Conventionally, when measuring the coordinate value of a point on a plane as described above, an operator measures using a length measuring device such as a tape measure, and each measurement obtained as a result of the measurement is performed.

From the measuring instrument main body 300 of the two-dimensional coordinate measuring apparatus, a measuring wire 39 is extended. The tip of the measurement cable 390 is fixed to the pointer 200. The pointer 200 is used to indicate a point to be measured.

As described above, the measuring instrument main body 300, the measuring cable 390, and the pointer 200 which constitute the two-dimensional coordinate measuring device are configured as shown in FIG. 2, for example. It is. In particular, the detailed structure of the measuring instrument main body 300 is as shown in FIGS. 3 and 4.

In FIG. 2, FIG. 3 and FIG. 4, the measuring instrument main body 300 is provided with a winding mechanism 320 functioning as a mechanism for pulling in the measuring cable 390. And a coordinate information acquisition mechanism for measuring a length and an angle of the point designated by the indicator with respect to the reference position and acquiring coordinate information.

In the present embodiment, the measuring device main body 300 has the above-described components housed in the case 311. In addition, the mounting position with respect to the support shaft 301 is determined so that the winding center of the winding mechanism 320 coincides with the reference device installation position 400. I'm afraid.

The draw-out pipe 360 functions as a mechanism for causing the measuring instrument main body 300 to follow the direction of the measuring cable 390. For this reason, The exit pipe 360 is located at the position where the extension of the central axis passes through the winding center of the winding mechanism 320 and is directed to the measuring instrument main body 300. It is attached to The pull-out pipe 360 can easily pull out the measuring cable 390, and measures the inner diameter with less play, that is, the inner diameter. It has a through hole that almost matches the outer shape of the rope 390. In addition, the total length is such a length that the parallelism of the case 311 with respect to the measurement cable 390 can be maintained, that is, the measurement cable 3900 is inserted into the case 311. Make it long enough to be able to straighten it with your mouth. For example, it is about 50 mm. By providing such an outlet pipe 360, the bending of the measuring cable 390 against the case 311 of the measuring cable 390 is suppressed, and the measuring cable 390 is formed. It is possible to accurately match the direction of case 311 with respect to the change in the drawing direction of the case.

The measuring cable 390 measures the distance by measuring the extension length thereof, and measures the angle by the direction of the measuring cable 390. It is used for For this reason, it is preferable that the measuring cable 390 use a wire with low elongation for tension.

Case 3 1 And a gear 333 for transmitting the relative angular displacement 1 to the angle measuring encoder 331. The angle measuring encoder 331 is initially set so as to be parallel to the direction of the origin unit 420, and sets the angle origin. The encoder for angle measurement 331 outputs a pulse signal according to the rotation angle and direction of the rotation axis 3221. The output pulse signal is sent to the up / down counter 370, where it is counted. If the rotation direction is positive, the camera will be up-counted, and if the rotation direction is negative, it will be down. Count. Therefore, the number of pulses corresponding to the angular displacement from the reference position is counted in the up-down counter 370. When an encoder with an absolute value scale is used as the angle measurement encoder, it can be used from any angle position.

The structure is designed to contact the The distance measuring encoder 341 generates a pulse signal corresponding to the rotational angular displacement and direction of the measuring roller 342. That is, it generates a number and types of pulses according to the amount and direction of the rotation. Output The pulse signal is sent to the UP / DOWN 370 and counted. If the rotation direction is positive (extend), the up-countdown will be performed and the rotation direction will be negative (upward). If it is a wrap / wind-up, download it. Therefore, the number of pulses corresponding to the distance from the reference position will be counted at 380 at the time of the down-counting.

The interface circuit 95 connects the data processing device to external devices and exchanges data. This embodiment In this case, the interface circuit 95 includes an up / down counter 370 of the measuring instrument body 300 and an up / down counter 380 And are connected.

The up-down counter 370 is connected to the angle measuring encoder 331 of the measuring instrument main body 300 described above. For example, the angle measuring The encoder corresponding to the direction in which the angle increases from the reference direction from encoder 331 is counted up, and the pulse in which the angle decreases from the reference direction is supported. Count down the pulse. In addition, on the up / down day 380, the measuring cable 390 from the distance measuring encoder 341 of the measuring instrument main body 300 is fed out. The pulse corresponding to the direction to be taken is counted up, and the pulse corresponding to the direction in which the measuring cable 390 is inserted is down-counted. The interface circuit 95 sets the count value of the up-down counter 370 as the angle data (6>), and sets the The count value of 380 is supplied to the bus 99 as distance data (R).

The up / down counter 370 and the up / down counter 380 are provided on the measuring instrument main body 300 and connected via a cable. It is connected to the evening circuit 95. Of course, the present invention is not limited to this. For example, the up-down counter 370 and the up-down counter 380 may be provided in the data processing device 500. No. In addition, the up-down countdown 370 and the up-down countdown 380 are independent devices with respect to the measuring instrument main body 300. Is also good. The two-dimensional coordinate measuring device measures the coordinates of each vertex (Pl, P2, P3) of the remaining material WK according to the principle shown in Figs. 7 (a) and 7 (b). . In other words, the two-dimensional coordinate measuring device has a measuring cable 3900 which is extended from the measuring device main body 300 when the operating rod 201 is set on the vertex of the remaining material WK. And the angle 0 between the direction (reference direction) connecting the measuring instrument main body 300 and the origin unit 420 to the measuring cable 390, and Measure and output the result as a pulse signal. More specifically, a pulse signal corresponding to the extended length R of the measurement cable 39 is generated and output by the extended displacement detector 34. . On the other hand, in the angular displacement detector 330, the direction connecting the measuring instrument main body 300 and the origin unit 420 (reference direction) and the measuring cable 39 are formed. A pulse signal corresponding to angle 0 is generated and output. Each of these pulse signals is counted by the corresponding up / down countdown 380 and up / down countdown 370, respectively. . Then, based on the count results, the coordinates (R, の) of each vertex of the remaining material WK can be obtained.

The shape information of each of the remaining materials WK1 to WK9 placed on the table 630 is stored in the data processing device 500 (see FIG.

1).

First, the operator sets the level 2 16 of the operating unit 210,

Set the operating rod 201 vertically on the origin unit 420 while observing 217. In that state, for example, the vertex registration key 2 1

If you continue to operate 1 and the registration end key 2 1 5 (meaning the registration operation of the initial angle value 0 0), the angle measurement enco The count value of the up / down count 370 that counts the pulses from the loader 331 is set as the initial angle value (0 0), and the memory Are stored in the default 20.

After that, the operator makes the operating rods 201 stand upright at the respective vertices of the remaining materials WK1 to WK9 placed on the table 630 in the same manner as described above. . Then, press the vertex registration key 2 1 1 every time the operating rod 2 1 is set upright. Then, for all the vertices necessary for shape specification in one remaining material, the vertex set keys 21 are operated when the same work is completed.

In the process in which the worker performs the above-described work, the CPU 10 of the data processing device 500 executes the processing according to, for example, the procedure shown in FIG.

In FIG. 8, the CPU 10 is in a state of waiting for an instruction input from the operation unit 210 of the operation stick 200 (S 1). In this state, the CPU 10 operates as described above. The corresponding transmit / receive unit 230 of the operation unit 210 transmits a signal in a corresponding form by the operation of the vertex registration key 211, and the signal is processed by the data processing device. When the communication unit 30 of the unit 500 receives (S2, YES), the count value of the up-counter 380 and the up-down The count value of the count 370 is obtained as the length data R and the angle data 0i, respectively (S2, S4). Then, the initial angle value 0 0 is subtracted from the angle data 0 i to obtain the angle data 0 (= 0 i−0 O).

Then, it is specified by the length data R and the angle data 0. The coordinates (R, θ) are registered as the coordinates of the specified vertex (S5). That is, the coordinates (R, Θ) are stored in the memory unit 20. Thereafter, the registered response signal is transmitted from the communication unit 30 of the data processing device 500 (S6).

When the transmission / reception unit 230 receives this registered response signal, the first response lamp 218 lights for a fixed time based on the received signal. The operator confirms that the coordinates of the point at which the operating rod 201 is raised have been registered by confirming that the first response lamp 218 is lit. I can do it. Thereafter, the operator moves the operating rod 201 to the next vertex of the remaining material WK. When the vertex registration key 211 is operated, a signal in a corresponding form is transmitted from the transmission / reception unit 230 of the operation unit 210, and the signal is transmitted. The data processing device 500 that has received the new vertex registers the coordinates (R, Θ) of the new vertex according to the same procedure (S1 to S6) as described above.

As described above, the operator completes the registration of all the vertices necessary for specifying the shape of one remaining material, and then registers the vertex set. Operate key 2 1 2. Then, the transmission / reception unit 230 of the operation unit 210 transmits a signal in a form corresponding to the vertex set registration key 2122. When the data processing device 500 receives a signal corresponding to the vertex set registration key 2 12 (S l, S 2, S 7, S 10), it is registered so far. The coordinates (R, Θ) correspond to the vertices of one piece of residual material, that is, the coordinates (R, Θ) corresponding to a set (one set) of vertices. , Θ) Information indicating that the set is the same is added (S11). Then, the registered response signal is transmitted from the communication unit 30 of the data processing device 500 (S12).

When this registered response signal is received by the transmission / reception unit 230 of the operation unit 210, the second response lamp 219 is activated based on the received signal. Lights for a fixed time. The operator confirms that the second response lamp 219 is lit, and recognizes that the coordinates of all the vertices of one remaining material have been registered as one set. You

In the process in which the operator sequentially designates each vertex of each of the remaining materials WK1 to WK9 by the pointer 200, the above-described registration processing of the coordinates of each vertex (S1 to S6) And the process of registering the registered coordinate group as one set (Sl, S2, S7, S10 to S12) is repeatedly executed. . Then, the worker who has finished the operation of pointing the respective vertexes of all the remaining materials WK1 to WK9 placed on the table 630 by the pointer 200 to the By illuminating the response lamp 2 19 of 2, the end of the process of registering the coordinates of each vertex as one set for all the remaining materials WK 1 to WK 9 is recognized. After that, operate the registration end key 2 15.

Then, a signal in a form corresponding to the registration end key 215 is transmitted from the transmission / reception unit 230. When this signal is received by the communication unit 30 of the data processor 500, the CPU 10 calculates the coordinates of the vertices of all the remaining materials WK1 to WK9 for each of the remaining materials. Then, it recognizes that the process for registering as a set should be terminated (S16), and terminates the process. On the other hand, in the process of registering the coordinates of each vertex of each remaining material, when the operator operates the vertex deletion key 2 13 of the operation unit 210, the transmission / reception unit is operated. A signal having a form corresponding to the vertex deletion key 2 13 is transmitted from the port 230. Then, the data processing device 500 that has received this signal (S7) deletes the coordinates (R, Θ) of the vertex registered immediately before from the memory unit 20. (S8). Thereafter, the deleted response signal is transmitted from the communication unit 30 of the data processing device 500 (S9). When the transmission / reception unit 230 of the operating unit 210 receives the deleted response signal, the first response lamp 218 is activated based on the deleted response signal. -Lights for a fixed time. After operating the vertex deletion key 2 12, the operator confirms that the first response lamp 2 18 is lit, so that the coordinates of the vertex specified immediately before are deleted. Recognize that it has been done.

In the same process, when the operator operates the vertex set delete key 214 of the operation unit 210, the vertex set is transmitted from the transmission / reception unit 230. A signal having a form corresponding to the set delete key 2 14 is transmitted. Then, the data processing device 500 receiving this signal (S13) stores the coordinates (R, Θ) of each vertex of one set registered immediately before in the memory unit. From the slot 20 (S14). Thereafter, the deleted response signal is transmitted from the communication unit 30 of the data processing device 500 (S15). When the transmission / reception unit 230 of the operation unit 210 receives the deleted response signal, the second response lamp 21 based on the deleted response signal is received. 9 lights up for a fixed time. After operating the vertex set deletion key 2 14, the operator confirms that the second response lamp 2 19 is lit, thereby confirming that the 1 set registered immediately before is turned on. Recognize that the coordinates of the vertices have been deleted.

As described above, the coordinates of each vertex of each remaining material placed on the table 630 are set and registered for each remaining material (memory unit). When the processing is completed, the CPU 10 further executes a processing for registering the shape information of each remaining material, for example, a procedure shown in FIG. And follow the instructions. This shape information is used to cut out small parts from the remaining material 1 to 1 <9 on the table 630 by using the ^ [0 cutting machine 600. This is the information to be provided, and represents the shape of each remaining material in the coordinate system set on the table 630.

In Fig. 9, the coordinates of each vertex registered as described above

The set of (R, Θ) is obtained (S21). The coordinates (R, 0) of one vertex are obtained from the set of the obtained coordinates (S22), and the coordinates (R, Θ) are converted to the table 6330. The above-mentioned cutting starting point 430 (see Fig. 1) set above is converted into coordinates in the orthogonal coordinate system X — Y with the origin as the origin.

(S23). This coordinate transformation is specifically performed as follows.

Polar coordinate system R — Coordinates (R, Θ) at 0 have the same origin. Cartesian coordinate system X — Y coordinates (X, Y)

X = Rcos 0

Y = R-sind

Is converted to Then, the origin of this Cartesian coordinate system is taped. The coordinate values X and Y are corrected so as to move to the cutting start origin 43 0 set on the rule 63 0. By such processing, the coordinates (R, Θ) of each vertex of the remaining material registered as described above are set to the cutting starting point set on the table 630. It is converted to the coordinates (X, Y) in the orthogonal coordinate system X — Y with the origin at 4330.

When the coordinate conversion processing as described above is completed, it is determined whether or not the coordinate conversion processing for all vertices registered as the set has been completed ( S2 4). If the coordinate transformation process has not been completed for all vertices, the coordinates (R, Θ) of a new vertex are obtained (S22), and the coordinates (R, R) are obtained. The above-mentioned coordinate conversion processing of Θ) is performed (S23). This coordinate conversion processing is repeatedly executed for the coordinates of all vertices registered as the set.

When the coordinate transformation process for all the coordinates of the vertices is completed (YES in S24), the coordinates (X, Y) after the coordinate transformation, which is the set, are used as the shape information. Then, it is stored (registered) in the memory unit 20 (S25).

Then, the above-described processing is executed for all sets of vertex coordinates, that is, for all remaining materials whose vertex coordinates have been measured (S26).

In the data processing device 500, as shown in Fig. 10, the coordinates (111, 0) of the vertices A, 8, and の of the residual material WK measured by the two-dimensional coordinate measuring device are used. 1), (R2, 6> 2), converted from (R3, θ3), set on table 630 By the coordinates (X1, Y1), (X2, Y2), (X3, Y3) in the coordinate system, the shape of the remaining material WK is recognized. That is, the coordinates (X1, Y1) and (Χ2, Υ2) of the vertices A and B specify the edge Α の of the remaining material WK, and the coordinates of the vertices 、 and C (縁 2, Υ 2) and (Χ 3, Υ 3) specify the edge BC of the residual material WK, and the coordinates (Xl, Yl), (Χ 3, Υ 3) of the vertices A and C. ), The edge AC of the remaining material WK is identified.

As described above, when the registration processing of the shape information of each remaining material is completed, the material and thickness of each remaining material from the operator using the input unit 50 are input. And input of management code, etc. is accepted. Further, when the registered shape information is instructed to be transferred to the NC cutting machine 600, the input information such as the material, thickness, and management code of each remaining material is input. In both cases, the shape information of the remaining materials WK1 to WK9 stored in the memory unit 20 is transferred from the LAN unit 40 to the NC cutting machine 600 via the LAN. It is done. The NC cutting machine 600 is provided with information such as the material and thickness of each of the remaining materials WK1 to WK9 placed on the table 630 and the shape information, and additionally. Based on the shape information of the parts to be cut out, a fine part is automatically cut out from each of the remaining materials WK1 to WK9 placed on the table 630.

According to the system described above, the operator only needs to operate the operation key of the operation unit 210 by setting the operation rod 201 at a point to be measured for coordinates. Then, the coordinates (R, Θ) of the point can be measured, and the measured data can be taken into a data processing system 500. I can do it. So Then, the data processing system 500 creates shape information of each remaining material from the measured data, and the NC cutting machine 600 creates each remaining information based on the shape information. It is possible to automatically cut out finer parts from the material.

The shape information of each remaining material stored in the memory unit 20 is stored in the flexible disk 90 via the FDD unit 70, and is stored in the flexible disk 90. By using the reciprocal disk 90, the shape information of each remaining material can be provided to the NC cutting machine 600.

In the above example, the instruction to register the measurement coordinates for each vertex is transmitted from the operation unit 210 to the data processing device 500 by wireless communication. However, it is also possible to communicate by wire communication. In addition, by placing the worker of the pointer 200 and another worker at the location where the data processing device 500 is installed, the worker of the pointer 200 can speak. It is also possible to issue the registration instruction directly to the operator of the data processing device 500. In this case, the operator of the data processing device 500 receiving an instruction from the operator of the pointer 200 inputs an instruction to import measurement data from the two-dimensional coordinate measuring device. By inputting the data using the slot 500, the measurement data at that point is taken into the data processing device 500.

At this point, the measuring instrument main body 300 and the data processing apparatus 500 are connected to each other, for example, as shown in FIG. You can do it. In FIG. 15, the shape identification device 700 is composed of a measuring instrument body (measuring instrument section) 300 and a data processing device (data processing section) 500. It has a connecting device 7100 for tying and a leg 720 for installing the data processing device 500. The configuration of the measuring unit 300 and the data processing unit 500 is basically the same as that described above (see FIGS. 2, 3, and 4). I explain mainly.

The measuring unit 300 is suspended from the bottom of the processing unit 500 via the connecting device 7100, and when the shape specifying device 700 is installed. So that it does not come into contact with the installation surface. In addition, the measuring unit 300 rotates relative to the data processing unit 500 on a horizontal plane with the connecting device 710 as an axis. For this reason, when the data processing section 500 is fixed to the installation surface via the leg section 720, the measurement cable 390 changes in the direction in which the measurement cable 390 is pulled out. Then, the measuring unit 300 is rotationally displaced. The measuring unit 300 may be provided at the rotation position not only below the data processing device 500 but also at the upper portion of the data processing device 500, for example. it can .

Above the data processing section 500, there is an input unit 500 used by the operator to input various information required for processing initial setting information and the like to the system. A liquid crystal panel screen 73 with an evening touch input function is provided, which has both functions of a display unit 60 for displaying input instructions for various information and the like. Yes. In addition, the side of the data processing section 500 reads and writes data to and from a flexible disk 90 for exchanging data with external devices. An FDD unit 70 for performing the operation is provided.

In the above, the angular displacement detector 330 was used as the measuring instrument case. It was provided within 3 1 1. However, as shown in FIG. 16, the angular displacement detector 33 can be provided in the data processing section 500. In this case as well, the angular displacement detector 330 is functionally included in the measuring section 300. It should be noted that there is no need to be able to provide the displaced displacement detector 340 and the like in the data processing section 500 as well.

Also, as described above, the rotational displacement of the reel portion of the winding mechanism 320 with respect to the case 311 is detected, and the rotational displacement is supplied to the angle measuring encoder 331. I was communicating. However, as shown in FIG. 16, the rotational displacement of the measuring section 300 with respect to the data processing section 500 is detected and transmitted to the angle measuring encoder 331, as shown in FIG. It can also be communicated.

In Fig. 16 (the parts other than those related to the main measuring instruments are omitted), the case 311 of the measuring base 300 is fixed to the connecting device 7110. Then, as the measuring base 300 rotates, the connecting device 7100 rotates. Then, the rotational displacement of the coupling device 7 10 is measured by the angular displacement detector 3 30.

The angular displacement detector 3330 includes an angle measuring encoder 331, a gear 3332 fixed to a connecting device 7110, and the angle measuring encoder 331. 21 While being fixed to the axis 1, it also engages with the gear 3 32, and calculates the relative angular displacement of the measurement base 300 with respect to the data processing section 500 for angle measurement. And a gear 333 for transmitting to the encoder 331.

Referring again to FIG. 1, the shape identifying device 700 is used for connection. The instrument 710 is installed so that the rotation axis of the measuring base 300 coincides with the reference instrument installation position 400. Then, as described above, the operator indicates each vertex of each of the remaining materials WK1 to WK9 by using the operating rod 201, etc. Material shape information can be registered in the data processing section 500. It should be noted that the present shape specifying device 700 cannot be used as a two-dimensional coordinate measuring device.

By connecting the measuring instrument main body 300 and the data processing device 500 in this way, the portability can be improved as the shape specifying device 700. It becomes possible.

Next, an example in which the above-described two-dimensional coordinate measuring device (see Fig. 2) is applied to a marking device will be described.

In this case, a marking mechanism is provided at the tip of the operating rod 201. This marking mechanism is configured, for example, as shown in FIG.

In FIG. 11, a marking block 205 is formed at the tip of the operation rod 201. At the tip of the marking block 205, a mark portion 222 impregnated with ink is provided. A moving pipe 206 is attached to the marking block 205 in a sliding manner. An opening 206 a is formed at the tip of the moving pipe 206 so that the mark portion 222 can protrude. A coil spring 220 is loaded between the periphery of the opening of the moving pipe 206 and the marking block 205. The coil spring 220 is provided with the mark section 220 so that the mark section 222 is always housed in the moving pipe 206. 2 0 Acts to push up.

At the upper end of the moving pipe 206, a mark switch 222 is fixed, and at the predetermined position on the outer periphery of the operation rod 200, a projection 224 is formed. ing . When the operating rod 201 is pressed against the repulsive force of the coil spring 220 and the mark part 222 reaches the opening surface of the moving pipe, The relative position of the mark switch 2 23 and the protrusion 2 24 is determined so that the protrusion 2 24 turns on the mark switch 2 23. Yes.

On the other hand, the operation unit 250 provided on the operation rod 201 is configured, for example, as shown in FIG. In FIG. 12, the operation unit 250 is a display panel 251, which displays a specified coordinate value, and a numeric keypad for inputting a coordinate value. 2 5 2, a match lamp 2 5 3, and a set key 2 5 4 for setting coordinate values are provided.

The control circuit of the operation unit 250 is configured, for example, as shown in FIG. In FIG. 13, the control unit 280 is operated by the ten keys 25 2, the set keys 25 4, and the operation signals from the mark switch 22 3. , And the encoders for the angle measurement of the two-dimensional coordinate measuring apparatus described above—the encoders 331 and the encoders for the distance measurement 341, respectively. Signal is being input. The control unit 280 displays the coordinate value data input by operating the numeric keypad 254 and the set key 254. Feed 1 The display panel 25 1 displays this coordinate value data. Further, the control unit 280 executes processing described later. The lighting control signal generated in accordance with the above is supplied to the matching lamp 24 3.

The encoder signal from the angle measuring encoder 331, and the encoder signal from the distance measuring encoder 341, are as follows. Each of them is transferred to the control unit 280 in the operation unit 210 in a wireless or wired manner.

The worker marks the predetermined plane (floor, board, wall, etc.) using a marking device as described above in the following manner.

The control unit 280 executes a process according to, for example, a procedure shown in FIG. 14 when the user puts the mark.

In FIG. 14, in a state where the measuring instrument main body 300 of the two-dimensional coordinate measuring device is set at a predetermined position in the same manner as in the above-described example, a coordinate system representing a position designated by an operator is provided. In order to specify the origin and the reference direction, the operating rod 201 is set upright at the point that determines the origin and the reference direction. In this case, the extension length of the measuring wire 390 and the angle of the measuring wire 390 at that time are the data indicating the origin and the reference direction. Then, it is obtained (S31). After that, the operator inputs the coordinate values (Xm, Ym) indicating the designated mark position by using the ten keys 25, and operates the set key 24. Then, the coordinate value is obtained as the mark position (S32). At this time, a coordinate value representing the mark position is displayed on the display panel 25 1.

In this state, the operator is required to specify the work stick 201. When it is moved in the direction of the laser position, it is based on the signals from the angle measuring encoder 331 and the distance measuring encoder 341. Then, the distance R from the origin of the moving position of the working rod 201 to the origin and the angle 0 from the reference direction are calculated (S33). Then, the coordinates (R, Θ) represented by the distance R and the angle β are converted to coordinates (X, Y) in the coordinate system X—Y representing the point designated by (S, S 3 4).

It is determined whether or not the point of the calculated coordinates (X, Y) is within a predetermined neighborhood of the mark position represented by the coordinates (Xm, Ym). (S35). Specifically, the calculated coordinate values X and Y are

X-6 ≤ X ≤ X + 6

Y m-(5 ≤ Y ≤ Y m + (5

Is determined to be within the range. The above 5 is determined based on the permissible error of the marking position.

If the coordinate values calculated as described above are not within the range, the above-described processing (S33, S34, S35) is repeatedly executed.

Then, when the operating rod 200 moved by the operator enters a predetermined vicinity range of the position to be marked, each of the calculated coordinate values is a value within the range. Is determined, and the lighting control signal is supplied from the control unit 280 to the matching lamp 253 (S36). As a result, the match lamp 253 lights up.

When the worker confirms that the matching lamp 2 53 is lit, the position of the work bar 201 is displayed on the display panel 25 1. Recognize that the position coincides with the position of the coordinates (X, Y). Then, when the work rod 201 is pressed against the plane to be marked, the marking block 205 is piled on the repulsive force of the coilless spring 220. Descend in the moving pipe 206. When the tip of the mark portion 222 reaches the plane, the mark is attached to the position by the ink of the mark portion 222 and the mark is attached to the position. The projection 2224 turns on the mark switch 223 (see FIG. 11B).

When the mark switch 2 23 is turned on, the control unit 280 recognizes that the mark is added (S27), and the next input is performed. Wait state. Then, when the next coordinate value is set by the numeric keys 25 2 and the set key 25 4, the same processing as described above is performed, and the next coordinate value is set. A mark is added to the specified position. On the other hand, when the end switch (for example, the * key of the ten keys 255) is operated, the processing at the control unit 280 ends.

According to the above-described marking device, the operator inputs the coordinate data of the position to be marked and moves the operating rod 201 in the process of moving the operating rod 201. By simply pushing the operation stick when the step 25 3 is lit, a mark can be added to the specified position.

The coordinate data of the position to be marked can also be provided to the operation unit 250 from outside by wire or wirelessly. INDUSTRIAL APPLICABILITY As described above, according to the present invention, a worker basically performs a task for a pointer to indicate a point at which coordinate measurement is to be performed. As a result, the coordinates of the point can be measured. Therefore, it is possible to provide a two-dimensional coordinate measuring device capable of measuring the coordinate value of a point on a plane with a simpler operation.

Further, according to the present invention, it is possible to provide a shape specifying device using the two-dimensional coordinate measuring device as described above.

Further, according to the present invention, a marking device using the two-dimensional coordinate measuring device as described above can be provided.
