Since a long opening is formed in the longitudinal direction of the rail R so that the marking portion 11i can mark the head surface of the rail R, the non-contact displacement amount measuring portion 11h, the marking portion 11i, and the like are formed on the main body case 11a. Since it is provided near the lower end, that is, near the head surface of the rail R, the non-contact type displacement amount measuring unit 11h, the marking unit 11i, and the like can be reliably protected.

(Fixing work of the rail head surface measuring device 1 of the first embodiment to the rail R)
Next, when the rail head surface measuring device 1 of the first embodiment is fixed to the rail R, the main body case 11a is installed on the head surface of the rail R, and the operator is in a stable state of the toggle as shown in FIG. 6, for example. As shown in FIG. 7, the link rotating shaft portion with a lever is pulled by grasping the lever portion 12d2 of the link portion 12d with a lever of the rail clamp mechanisms 12 and 12 at both ends in the longitudinal direction of the main body case 11a in the (stationary state). When the link portions are connected to each other and the rotation shaft portion 12e2 is moved upward from the straight line connecting 12d1 and the link rotation shaft portion 12d1 without a lever, the stable state of the toggle is released, and the rail is released by the tensile force of the toggle tension spring 12g. The space between the lower ends (tips) of the clamps 12c and 12c is wider than the width of the head of the rail R, and finally the link portions are connected to each other. In contact with the upper end of the elongated hole 12b2 for guiding the vertical movement of the rotating shaft, the raising operation of the rail clamps 12c, 12c, the vertical slide plate 12b, etc., and the lower end (tip) of the rail clamps 12c, 12c The opening operation of is stopped.

Next, the operator grasps the lever portion 12d2 of the link portion 12d with a lever, and the rail clamp portions 12c and 12c and the vertical slide plate 12b in a state where the lower end portions are open against the vertical slide tension springs 12f and 12f. Etc. are pushed downward, and when the rear end of the rotating shaft portion 12e2 that connects the link portions comes into contact with the lower end portion of the rotating shaft vertical movement guiding elongated hole 12b2 of the rotating shaft vertical movement guide portion 12b1, the rail The descent of the clamp portions 12c and 12c and the vertical slide plate 12b and the like is stopped, and the lower end portions (tip portions) of the rail clamp portions 12c and 12c reach the neck portion (jaw portion) below the rail R head in an open state.

Then, when the operator further pushes down the lever portion 12d2 of the link portion 12d with the lever, the link portion 12d with the lever and the link portion 12d without the lever rotate around the rotation shaft portion 12e2 for connecting the link portions and gradually become horizontal. The lower ends of the rail clamps 12c and 12c that were wider than the head width of the rail R by expanding and slightly pulling up the link rotating shaft portion 12d1 with the lever and the link rotating shaft portion 12e1 without the lever. Pull up while closing between the parts (tips), and finally, as shown in FIG. 5, the head of the rail R is clamped by the rail clamp parts 12c and 12c, and the link rotating shaft part 12d1 with the lever and the link without the lever are finally clamped. The link portions are connected to each other with respect to the straight line connecting the rotating shaft portion 12d1, and the rotating shaft portion 12e2 moves downward to enter a stable state (stationary state) of the toggle.

At the same time, the pulling springs 12f and 12f for vertical sliding urge the rail clamp portions 12c and 12c in the ascending direction by the force to be contracted, and are applied to the neck portion (jaw portion) of the rail R as shown in FIG. The inner side surfaces of the rail clamp portions 12c and 12c tips come into contact with each other.

Therefore, according to the rail clamp mechanisms 12 and 12 of the rail head surface measuring device 1 of the first embodiment, the rail head surface measuring device 1 can be easily fixed to the rail R with one touch by operating the link portion 12d with a lever. Therefore, it is not necessary to fix the rail head surface measuring device 1 to the rail R with screws, bolts, or the like, and workability can be improved.

(Measuring work of the amount of displacement of the unevenness of the rail R head surface by the rail head surface measuring device 1 of the first embodiment)
After fixing the rail head surface measuring device 1 of the first embodiment to the rail R as described above, the work of measuring the displacement amount of the unevenness of the rail R head surface is started.

FIG. 8 is a flowchart showing the operation of the rail head surface measuring device 1 of the first embodiment.

As shown in FIG. 8, when the rail head surface measuring device 1 starts operating by turning on the power of the data processing communication terminal 13 wirelessly connected to the measuring device main body 11, the CPU of the data processing communication terminal 13 (not shown). ) Enters the on-waiting state of the power switch 11d3 on the measuring device main body 11 side (step S100).

Then, when the operator turns on the power switch 11d3 of the measuring device main body 11 (step S200 “Yes”), the direct current of the optimum voltage is transmitted from the battery 11d1 via the DC / DC converter 11d2 to the drive unit 11e, the main body control unit 11j, etc. The main body control unit 11j performs a predetermined initial process, and as one process of the initial process, attempts wireless communication with the data processing communication terminal 13 via the communication processing unit 11j4 to see if data communication is possible (step S300).

Then, when the communication processing unit 11j4 of the measuring device main body 11 normally completes the wireless connection with the data processing communication terminal 13 (step S400 “Yes”), the CPU 11j1 of the main body control unit 11j resets the rotation speed of the rotary encoder 11e5. Perform the measurement preparation work of the rail R head surface such as initialization of various data (step S500), and then perform the measurement process of the displacement amount of the unevenness of the rail R head surface, which is shown in detail in FIG. Execute (step S600).

FIG. 9 is a flowchart showing in detail the displacement amount measurement process of the rail R head surface in the main body control unit 11j in step S600 in FIG.

In the displacement amount measurement process of the rail R head surface in step S600 in FIG. 8, first, the CPU 11j1 of the main body control unit 11j enters the reception waiting state of the displacement amount measurement start signal from the data processing communication terminal 13 (step S605).

Then, the operator operates the data processing communication terminal 13 to transmit a displacement amount measurement start signal from the data processing communication terminal 13 to the measuring device main body 11, and the CPU 11j1 of the main body control unit 11j on the measuring device main body 11 side performs communication processing. When the displacement amount measurement start signal is received via the unit 11j4 (step S610 “Yes”), the CPU 11j1 of the main body control unit 11j first returns the carrier 11c to the start point of the measurement section with respect to the motor driver 11e3 of the drive unit 11e. The rotation command of the traveling motor 11e2 is sent (step S615).

Then, the motor driver 11e3 rotates the traveling motor 11e2 based on the rotation command of the traveling motor 11e2 from the CPU 11j1 of the main body control unit 11j, and meshes with the rack gear 11b1 on the side surface of the guide plate 11b. Carrier 11c that rotates and carries a power supply unit 11d, a drive unit 11e, a start point position detection sensor 11f, an end point position detection sensor 11g, a non-contact displacement amount measurement unit 11h, a marking unit 11i, a main body control unit 11j, and the like. Is moved toward the start point of the measurement section (step S620). If it is FIG. 1, it is moved to the right in the figure.

Then, when the carrier 11c is moving along the guide plate 11b, the start point position detection sensor 11f provided on the carrier 11c approaches the guide plate support portion 11k1 on the start point side of the guide plate 11b close to the dog 11k11 and the start point. When the position detection sensor 11f is turned on (step S625 “Yes”), the carrier 11c has reached the start point of the measurement section. Therefore, the CPU 11j1 of the main body control unit 11j issues a stop command to the motor driver 11e3 of the drive unit 11e. The rotation of the traveling motor 11e2 is stopped to stop the traveling of the carrier 11c (step S630), and the uneven displacement amount of the rail R head surface at the starting point is acquired as measurement data from the non-contact type displacement amount measuring unit 11h (step S630). Step S635). Here, the method of measuring the uneven displacement amount of the rail R head surface by the non-contact type displacement amount measuring unit 11h is the same as the conventional method and is measured by the well-known non-contact type eddy current method, and thus the description thereof will be omitted. Further, when it is not necessary to stop the traveling of the carrier 11c when measuring the uneven displacement amount of the rail R head surface at the starting point, the process of step S630 can be omitted.

When the measurement of the uneven displacement amount of the rail R head surface by the non-contact type displacement amount measuring unit 11h at the starting point is completed, the CPU 11j1 of the main body control unit 11j mainly uses the measurement data of the uneven displacement amount of the rail R head surface at the starting point. It is stored in the memory 11j2 and the detachable memory card 11j3 (step S640), and is transmitted to the data processing communication terminal 13 via the communication processing unit 11j4 (step S645). The CPU 11j1 of the main body control unit 11j includes the measurement data of the uneven displacement amount of the rail R head surface of the starting point measured in the processes of steps S640 and S645, as well as the number of pulse signals generated by the rotary encoder 11e5 at the starting point and the number thereof. Of course, other data such as the position data of the starting point based on the number of pulse signals may be stored or transmitted. Further, in the storage process of step S640, the measurement data of the uneven displacement amount of the rail R head surface at the starting point may not be stored in the main memory 11j2, but may be stored only in the removable memory card 11j3.

Next, the CPU 11j1 of the main body control unit 11j outputs a movement start command from the start point to the end point of the measurement section to the motor driver 11e3 of the drive unit 11e, rotates the traveling motor 11e2, and sets the carrier 11c as the end point. Move toward (step S650).

When the carrier 11c is moved, the CPU 11j1 of the main body control unit 11j counts the out-of-phase A-phase and B-phase pulse signals (see FIG. 10 described later) output from the rotary encoder 11e5 (step S655). , The traveling direction of the carrier 11c and the moving distance from the start point are measured to determine whether or not the carrier 11c has reached the next measurement point (measurement point) (step S660). Here, the CPU 11j1 of the main body control unit 11j becomes a measurement point every three cycles (for example, 30 mm) of the A-phase pulse signal output from the rotary encoder 11e5 as shown in FIG. 10 described later. However, the present invention is not limited to this.

Then, when the CPU 11j1 of the main body control unit 11j determines that it is a measurement point (measurement point) every three cycles of the A-phase pulse signal output from the rotary encoder 11e5 (step S660 “Yes”), at each measurement point. The uneven displacement amount of the rail R head surface is acquired from the non-contact type displacement amount measuring unit 11h (step S665).

10 (a) to 10 (d) show the A-phase pulse signal and the B-phase pulse signal output from the rotary encoder 11e5, the displacement amount (analog signal) of the rail R head surface, and the rail head surface measuring unit 11h, respectively. It is a timing chart which shows an example of the measurement data (digital signal) of the uneven displacement amount of the rail R head surface measured by.

As described above, in the rail head surface measuring device 1 of the first embodiment, when the carrier 11c is moved, the CPU 11j1 of the main body control unit 11j is shown in FIGS. 10A and 10B output from the rotary encoder 11e5. The non-contact displacement amount measuring unit 11h counts the A-phase and B-phase pulse signals that are out of phase with each other, and the non-contact displacement amount measuring unit 11h counts the pulse signals of the A-phase for three cycles (for example, 30 mm) based on the control of the CPU 11j1 of the main body control unit 11j. .) For each measurement, the amount of uneven displacement of the rail R head surface that is displaced as shown in FIG. 10 (c) is measured, and as shown in FIG. 10 (d), the measurement data of the amount of uneven displacement of the rail R head surface (. A digital signal) is obtained and output to the CPU 11j1 of the main body control unit 11j.

When the CPU 11j1 of the main body control unit 11j inputs the measurement data (digital signal) of the unevenness of the rail R head surface at each measurement point from the non-contact type displacement amount measuring unit 11h, the unevenness of the rail R head surface at each measurement point The measurement data of the displacement amount is stored in the main memory 11j2 and the detachable memory card 11j3 (step S670), and is transmitted to the data processing communication terminal 13 via the communication processing unit 11j4 (step S675). In the processing of step S670 and step S675, similarly to the processing of step S640 and step S645, the rotary encoder 11e5 was generated at each measurement point together with the measurement data of the uneven displacement amount of the rail R head surface at each measurement point. Of course, other data such as the number of pulse signals and the position data of each measurement point based on the number of pulse signals may be stored or transmitted. Further, in the storage process of step S670, the measurement data of the uneven displacement amount of the rail R head surface at each measurement point may not be stored in the main memory 11j2, but may be stored only in the removable memory card 11j3.

Further, the CPU 11j1 of the main body control unit 11j always determines whether or not an on signal is output from the start point position detection sensor 11f or the end point position detection sensor 11g provided on the carrier 11c while the carrier 11c is traveling. (Step S680), if the on signal is not output from the end point position detection sensor 11g (step S680 “No”), the process returns to step S655 and the phase A and B output from the rotary encoder 11e5 are out of phase. The phase pulse signals are counted, and the above-described processes of steps S655 to S680 are repeated.

On the other hand, when the ON signal is output from the end point position detection sensor 11g (step S680 “Yes”), it means that the carrier 11c has reached the end point on the side opposite to the start point. Therefore, the CPU 11j1 of the main body control unit 11j will be described later. In order to mark the portion requiring correction in step 694, a reverse rotation command is sent to the motor driver 11e3 of the drive unit 11e to reversely rotate the traveling motor 11e2 to return the carrier 11c to the starting point (step S685).

This is usually done by measuring the amount of uneven displacement of the rail R head surface with a rail head surface measuring device such as the rail head surface measuring device 1 of the first embodiment, and then using a straightening device or the like to measure the convexity of the rail R head surface. This is because the correction work of the part is performed.

Therefore, in the rail head surface measuring device 1 of the first embodiment, after the displacement amount measuring work of the rail R head surface, the CPU 11j1 of the main body control unit 11j smoothly corrects the rail R head surface by another correction device or the like. After the measurement process of the uneven displacement amount of the rail R head surface to the end point is completed, the measurement data of the uneven displacement amount of the rail R head surface at each measurement point stored in the main memory 11j2 or the memory card 11j3 or the like. Based on the above, it is determined whether or not there is a convex portion having a large displacement so that it is necessary to perform the correction work on the rail R head surface at each measurement point from the start point to the end point. Step S690).

The process of determining whether or not there is a required correction is performed by using the measurement data of the uneven displacement amount of the rail R head surface at each measurement point stored in the main memory 11j2 or the memory card 11j3 by the CPU 11j1 of the main body control unit 11j. For example, based on the pulse signal output from the rotary encoder 11e5, the measurement data at each measurement point continuously rises by a predetermined number or more of the pulse signals output from the rotary encoder 11e5, and then continuously increases by a predetermined number or more of the pulse signals. In the case of continuous descent, it can be determined that there is a point requiring correction in which the amount of displacement of the convex portion is so large that the measurement data needs to be corrected at or around the measurement point where the measurement data is switched from rising to descending.

For example, when the CPU 11j1 of the main body control unit 11j sets, for example, “6” as a predetermined number of pulse signals output from the rotary encoder 11e5, the pulse signals output from the rotary encoder 11e5 at the point α in FIG. Since the measurement data of the uneven displacement amount of the rail R head surface is rising and falling for 6 pulses or more, the point α can be determined as a necessary point. By appropriately setting a predetermined number of pulse signals output from the rotary encoder 11e5, it is necessary to correct the convex portion with a large displacement amount so that it needs to be corrected on the rail R head surface. It is possible to distinguish from a fine convex portion in which the displacement amount of the convex portion is so small that it can be ignored on the rail R head surface which is not necessary. That is, when, for example, "6" is set as a predetermined number of pulse signals, if the pulse signals do not rise continuously for 6 pulses or more, for example, if only 3 pulses are continuous, it is necessary to correct them. It can be discriminated as a fine convex portion in which the displacement amount of the convex portion is small to the extent that it can be ignored on the rail R head surface.

Then, when it is determined that there is a portion requiring correction on the rail R head surface based on the measurement data of the uneven displacement amount of the rail R head surface at each measurement point (step S692 “Yes”), the CPU 11j1 of the main body control unit 11j determines. It is necessary to store the carrier 11c in the main memory 11j2 or the memory card 11j3 while moving the carrier 11c from the start point to the end point so that the correction necessary part can be corrected by a correction device (not shown) or the like after the measurement. When the marking unit 11i reaches above the location requiring correction, a print command is output to the marking unit 11i based on the pulse signal which is the position data of the location and the pulse signal output from the rotary encoder 11e5. , Ink or the like is sprayed on the required correction portion to mark it (step S694).

Then, when the marking process of the required correction portion is completed while moving the carrier 11c in step S694 from the start point to the end point, the CPU 11j1 of the main body control unit 11j sends a reverse rotation command to the motor driver 11e3 of the drive unit 11e. The traveling motor 11e2 is rotated in the reverse direction to return the carrier 11c to the starting point (step S696), and the measurement process of the uneven displacement amount of the rail R head surface in step S600 is completed.

In the process of measuring the uneven displacement amount of the rail R head surface in step S696 of the first embodiment, the carrier 11c is moved to the starting point by the process of step 620. Therefore, in the process of step 685, the carrier 11c is not returned to the starting point. It may be returned to the vicinity of the start point, or further, the rotation of the traveling motor 11e2 may be stopped, and the carrier 11c may be stopped at the end point or near the end point.

Further, in the present invention, the marking process of the required correction portion is an arbitrary process, and when the marking process of the required correction portion is not required, the marking portion 11i is omitted and the processes of steps S685 to S694 are omitted. You may. Further, when returning the carrier 11c from the end point to the start point, the marking process of the required correction portion in step S694 may be executed, and when returning the carrier 11c from the end point to the start point, the marking process of the required correction portion in step S694 may be executed. When executing, in the process of returning the carrier 11c of step S685 to the starting point, the processes of steps S690 to S694 are performed, and the process of step S696 is omitted.

<Main effect of the rail head surface measuring device of the first embodiment>
As described above, in the rail head surface measuring device 1 of the first embodiment, the traveling motor 11e2 is provided and the carrier 11c traveling along the guide plate 11b and the carrier 11c are provided, and the carrier 11c is provided on the guide plate 11b. Since it is provided with a non-contact type displacement amount measuring unit 11h that measures the displacement amount of the rail R head surface in a non-contact manner when traveling along the rail R, it is a sensor even when the gap between the joints of the rail R is large. The work of floating the contact type displacement amount measuring unit 11h becomes unnecessary, and the burden on the operator can be reduced.

In particular, in the rail head surface measuring device 1 of the first embodiment, the carrier 11c is self-propelled along the guide plate 11b by the traveling motor 11e2, and the non-contact displacement amount measuring unit 11h measures the displacement amount. It is not necessary to manually measure the uneven displacement amount of the head surface of the rail R while moving the non-contact type displacement amount measuring unit 11h in the longitudinal direction of the rail R, and the burden on the operator can be reduced in this respect as well.

Further, in the rail head surface measuring device 1 of the first embodiment, the guide plate 11b and the carrier 11c have a non-contact type displacement amount measuring unit 11h on the bottom surface at least from the start point to the end point of the displacement amount measurement, and the unevenness of the rail R head surface is formed. It is provided in a box-shaped main body case 11a having a rectangular shape in a plan view, in which a long opening is formed in the longitudinal direction of the rail R so that the displacement amount can be measured and the marking portion 11i can mark the head surface of the rail R. The rail R head is clamped to the outside of the case front side surface 11a1 and the case rear side surface 11a2 in the longitudinal direction of the main body case 11a, respectively, as shown in FIG. 5, and the rail R head is clamped as shown in FIG. In the retracted state, the link portions are connected to each other with respect to the straight line connecting the link rotation shaft portion 12d1 with the lever and the link rotation shaft portion 12d1 without the lever. Rail clamps 12c, 12c that maintain a stable state (stationary state) by contacting the rear end of the moving shaft portion 12e2 with the lower end of the rotating shaft vertical movement guiding elongated hole 12b2 of the rotating shaft vertical movement guide portion 12b1. Is provided.

Therefore, according to the rail head surface measuring device 1 of the first embodiment, the rail head surface measuring device 1 can be attached to the rail R by a simple one-touch operation of lowering or raising the link portion 12d with a lever of the rail clamp mechanisms 12 and 12. Since it is possible to fix or release the rail head surface measuring device 1, it is not necessary to fix the rail head surface measuring device 1 to the rail R with screws, bolts, or the like, and workability can be improved.

Further, in the rail head surface measuring device 1 of the first embodiment, the carrier 11c is further printed on the rail head surface based on the measurement data of the displacement amount measured by the non-contact type displacement amount measuring unit 11h. A marking unit 11i for marking is provided, and the CPU 11j1 of the main body control unit 11j has a rail R head surface in the measurement section based on the measurement data of the uneven displacement amount of the rail R head surface at each measurement point stored in the memory card 11j3. If it is determined that there is a required correction point, a printing command is output when the marking unit 11i reaches the required correction point upward so that the necessary correction point can be corrected by the correction device after measurement. It is controlled so that the required correction is marked with ink or the like.

Therefore, according to the rail head surface measuring device 1 of the first embodiment, when there is a portion requiring correction on the rail R head surface in the measurement section, the marking portion 11i marks the rail R head surface with ink or the like, so that the amount of displacement of the rail R head surface is increased. After the measurement, when the necessary part for correction is corrected by a correction device which is another device, the correction can be performed efficiently.

Embodiment 2.
In the rail head surface measuring device 1 of the first embodiment, the adjustment mechanism of the non-contact type displacement amount measuring unit 11h in the direction orthogonal to the longitudinal direction of the rail R, that is, in the lateral direction of the rail R is not provided. A slide mechanism 11m for measuring the amount of displacement of the rail R in the lateral direction is provided on the measuring device main body 11 of the rail head surface measuring device 1 of the second embodiment. This is the same as the rail head surface measuring device 1 of the first embodiment.

FIG. 11 is a diagram showing a state in which the rail head surface measuring device 1 of the second embodiment is mounted on the rail and the configuration inside the main body case, and FIG. 12 is a non-contact displacement amount in the rail head surface measuring device 1 of the second embodiment. FIG. 5 is a cross-sectional view in a state where a carrier 11c provided with a measuring unit 11h, a displacement amount measuring unit slide mechanism 11m, or the like is located at a starting point.

As shown in FIGS. 11 and 12, in the rail head surface measuring device 1 of the second embodiment, the displacement amount measuring unit slide mechanism 11m is provided on the bottom surface of the carrier 11c traveling along the guide plate 11b, and the displacement amount measuring unit slides. A non-contact displacement amount measuring unit 11h is attached to the mechanism 11m.

The displacement amount measuring unit slide mechanism 11m has an adjustment knob 11m1 that adjusts the position of the non-contact type displacement amount measuring unit 11h in the lateral direction of the rail R by being grasped and rotated by an operator, and the rotation of the adjustment knob 11m1. It has an adjusting gear 11m2 that rotates, and a feed screw portion 11m3 that rotates by the rotation of the adjusting gear 11m2 to move the non-contact type displacement amount measuring unit 11h in the lateral direction of the rail R.

Further, in the rail head surface measuring device 1 of the second embodiment, the carrier 11c provided with the non-contact type displacement amount measuring unit 11h, the displacement amount measuring unit slide mechanism 11m, etc. is housed in the main body case 11a surrounded on all sides. As shown in FIG. 12, the operator grabs and rotates the adjustment knob 11m1 of the displacement amount measuring unit slide mechanism 11m at the starting point position on the case right side surface 11a4 of the main body case 11a of the second embodiment. An opening 11a41 for working with an adjustment knob is provided so that the adjustment knob can be used.

Therefore, according to the rail head surface measuring device 1 of the second embodiment, the displacement amount is measured by the non-contact type displacement amount measuring unit 11h as in the rail head surface measuring device 1 of the first embodiment, so that the joint of the rails R is jointed. Even when the clearance between the two is large, the work of floating the non-contact displacement amount measuring unit 11h, which is a sensor, becomes unnecessary, the burden on the operator can be reduced, and the carrier 11c is attached to the guide plate 11b by the traveling motor 11e2. Since the non-contact type displacement amount measuring unit 11h runs along the line and measures the displacement amount, the operator does not have to pull the non-contact type displacement amount measuring unit 11h by hand, which also reduces the burden on the operator. can.

Further, since the rail head surface measuring device 1 of the second embodiment also has the same rail clamping mechanisms 12 and 12 as the rail head surface measuring device 1 of the first embodiment, the rail head surface measuring device 1 can be mounted on the rail R with screws, bolts, or the like. Since it is not necessary to fix the rail R to the rail, workability can be improved, and the marking portion 11i is also provided, the rail R head surface can be efficiently subjected to the rectifying work by the rectifying device after the displacement amount is measured.

Further, in the rail head surface measuring device 1 of the second embodiment, since the non-contact type displacement amount measuring unit 11h is attached to the bottom surface of the carrier 11c traveling along the guide plate 11b via the displacement amount measuring unit slide mechanism 11m, it is not. The contact type displacement amount measuring unit 11h can be adjusted to move in the lateral direction of the rail R, and the displacement amount on the central portion of the crown surface of the rail R or on either the left or right end side can be measured more accurately.

In the description of the first and second embodiments, the case where the battery 11d1 of the power supply unit 11d is depleted and the carrier 11c is stopped on the guide plate 11b is not described. For example, the carrier 11c is a rail R. If there is no charge amount to return to the starting point after finishing the measurement of the head surface, the operator may not have enough charge amount of the battery 11d1 by turning on or blinking an LED (not shown), or the battery 11d may be replaced.
