Furthermore, when the processing apparatus 100 is selected via the input unit 110, halation (a phenomenon of white blurring) occurs in the first mode, which is the standard mode, and the subject X having a high light reflectance. It is possible to switch between the second mode, which is a mode for suppressing the above.

  The control unit 130 controls the movement unit 34 to move the work table 3, the driving unit 33 controls the rotation control unit 132 to rotate the stage 31, and each reading unit 21. , 22, and 23. The control unit 130 includes a storage unit 134 that stores data of the subject X read by the reading units 21, 22, and 23, and a calculation unit 135 that calculates the acquired data.

  When the first mode is selected, the reading control unit 133 reads the subject X with both the light sources 211 (221, 231) and 211 (221, 231) turned on. Each reading unit 21, 22, 23 is controlled. In addition, when the second mode is selected, the reading control unit 133 reads the subject X with only one light source 211 (221, 231) turned on, and then the other light source 211 (221, 221). 231) Only the reading units 21, 22, and 23 are controlled so as to read the subject X with only the light on.

Specifically, the calculation unit 135 creates one image (data) from one two-dimensional data acquired by the reading units 21, 22 and 23 reading the subject X.

  In addition, when the second mode is selected, the calculation unit 135 reads the first data obtained by reading the subject X with only one light source 211 (221, 231) turned on, and the other mode. The second data acquired by reading the subject X in a state where only the light source 211 (221, 231) is turned on is synthesized and imaged. Specifically, the computing unit 135 compares the first data and the second data for each pixel and extracts only the data with the smaller received light amount, thereby obtaining the two-dimensional data. One image (data) is created.

  As described above, the scanner device 1 according to the present embodiment relatively moves the reading unit 2 that reads the subject X and the stage 31 on which the subject X is placed relatively in the horizontal direction by moving the work table 3 in the horizontal direction. Can be displaced. As a result, it is possible to prevent the end side of the subject X in the horizontal direction from being distorted and read.

  Since the stage 31 can rotate about the vertical direction and can tilt with respect to the horizontal direction, the positional relationship between the reading unit 2 and the subject X can be flexibly handled. Therefore, as described above, it is possible to accurately read the subject X while suppressing distortion of the end side, and to read the subject X at a desired position.

  In the scanner device 1 according to the present embodiment, the stage 31 can be rotated around the vertical direction because the stage 31 is connected to the rotating unit 32 that rotates about the vertical direction. Furthermore, since the stage 31 can be rotationally displaced about the horizontal direction with respect to the rotating unit 32, the stage 31 can be inclined with respect to the horizontal direction. In addition, since the rotation center and the rotation center of the stage 31 are orthogonal to each other, the subject X can be stably rotated even if the stage 31 is rotated around the vertical direction.

  Further, in the scanner device 1 according to the present embodiment, since the placement unit 311 located at the center of the stage 31 is configured to be translucent, the reading unit 2 is configured to transmit light through the translucent placement unit 311. The subject X can be read from below. Since the stage 31 is pivotally attached to the rotating part 32 arranged on the outer side at the outer peripheral part, when the reading means 2 reads the subject X from the lower side, a reading obstacle is located below the stage 31. As a result, the reading unit 2 can easily read the subject X from the lower side.

  In the scanner device 1 according to the present embodiment, the connecting portion 312 is pivotally attached to the rotating portion 32 by the second rotating shaft 312b arranged along the horizontal direction. Can be rotated. And since the mounting part 311 is pivotally attached to the connection part 312 by the 1st rotation axis | shaft 311a arrange | positioned along a horizontal direction, the mounting part 311 can be rotated in a predetermined range.

  Moreover, the rotation shafts 311a and 312b are arranged so as to be orthogonal to each other. Therefore, in addition to the fact that the mounting portion 311 can rotate around the vertical direction, any reading angle and any reading direction can be supported within a predetermined range in which the mounting portion 311 and the connecting portion 312 can rotate.

  Further, the scanner device 1 and the processing device 100 according to the present embodiment can read the subject X from the upper side, the lower side, and the side side by the reading units 21, 22, and 23, and the rotation control unit 132. By rotating the stage 31, the position to be read from the side of the subject X can be changed. Further, when the rotation control unit 132 detects the rotation angle, the position data of the subject X read by the reading unit 2 can be stored in the storage unit 134.

  Therefore, for example, for the subject X, it is possible to acquire data related to the six faces of the third trigonometry (plane (upper surface), bottom surface (lower surface), front, back, right side, and left side). FIG. 10A shows the case where the first mode is selected and the data relating to the front of the subject X is imaged (image processing).

  Further, the scanner device 1 and the processing device 100 according to the present embodiment switch between the first mode, which is a standard mode, and the second mode, which is a mode for suppressing the occurrence of halation, via the input unit 110. be able to. Therefore, as shown in FIG. 10A, by selecting the second mode for the subject X that causes halation, the object X that does not cause halation as shown in FIG. 10B is selected. Images can also be acquired.

  It should be noted that the scanner device according to the present invention is not limited to the above-described embodiment, and it is needless to say that various changes can be made without departing from the gist of the present invention. Moreover, it is needless to say that configurations, methods, and the like according to various modifications described below may be arbitrarily selected and employed in the configurations, methods, and the like according to the above-described embodiments.

  First, in the scanner device 1 according to the above-described embodiment, the stage 31 includes the placement portion 311 and the connection portion 312, the placement portion 311 and the connection portion 312 pivot, and the connection portion 312 and the rotation portion 32 pivot. Although the case where the stage 31 is inclined with respect to the horizontal direction by wearing is described, it is not limited to such a case.

  For example, the stage has only the placement portion 311 (not having the configuration of the connection portion 312), and the placement portion 311 and the rotation portion 32 are pivotally attached, so that the stage is inclined with respect to the horizontal direction. The stage may not be inclined with respect to the table body, but may be inclined with respect to the horizontal direction when the table body is inclined. Furthermore, the stage may be inclined with respect to the horizontal direction by a spherical bearing, and an example of such a case is shown in FIG.

  The work table 5 shown in FIG. 11 includes a stage 51 on which an object X is placed, a shaft rotating unit 53 that is rotated by a driving unit 52, and a center of the stage 51 so that the stage 51 is inclined with respect to the horizontal direction. And a spherical bearing portion 54 for spherically bearing the tip portion of the rotating portion 53. The work table 5 also includes first and second angle adjusting means 55 and 56 that adjust the tilt angle of the stage 51.

  The respective angle adjusting means 55 and 56 are inserted into the rotating unit 53 and move along the axial direction of the rotating unit 53 (G arrow direction, H arrow direction in FIG. 11 and the vertical direction). And link mechanisms 552 and 562 for connecting the respective moving bodies 551 and 561 and the stage 51. Each link mechanism 552, 562 is connected to any one of the moving bodies 551, 561 and the stage 51 by a spherical bearing (in FIG. 11, each link mechanism 552, 562 is connected to the stage 51 and the spherical surface. Are connected by bearings 552a and 562a).

  According to such a configuration, the first angle adjusting means 55 can turn the stage 51 around a predetermined horizontal direction, and the second angle adjusting means 56 is perpendicular to the predetermined direction and centered in the horizontal direction. The stage 51 can be rotated. Therefore, similarly to the scanner device 1 according to the above-described embodiment, any reading angle and any reading direction can be handled within a rotatable range.

  In the scanner device 1 according to the above-described embodiment, the case where the connecting portion 312 is formed in an annular shape and the rotating portion 32 is formed in an annular shape has been described. However, the present invention is not limited to such a case. For example, FIG. 12 shows an example of a configuration that does not have a configuration that obstructs reading below the stage so that the subject X can be easily read from below the stage.

  The work table 6 shown in FIG. 12 includes a stage 61 having a circular mounting portion 611 and an arc-shaped connecting portion 612 disposed radially outward from the mounting portion 611. Then, the work table 6 transmits the drive of the rod-shaped rotating unit 62 arranged radially outward from the connection unit 612 and the driving source 631 to the rotating unit 62 by the transmission unit 632, and the rotating unit 62 is transmitted in the vertical direction. Driving means 63 for rotating around the center.

  The placement portion 611 is pivotally attached to the connection portion 612 with a first rotation shaft 611a disposed along the horizontal direction, and the connection portion 612 is disposed along the horizontal direction and the first rotation. A second rotating shaft 612 a disposed along a direction orthogonal to the moving shaft 611 a is pivotally attached to the rotating portion 62. Therefore, according to such a configuration, as in the scanner device 1 according to the above-described embodiment, any reading angle and any reading direction can be handled within a rotatable range.

  In the scanner device 1 according to the above-described embodiment, the case where the reading unit 2 includes the upper surface reading unit 21, the lower surface reading unit 22, and the side surface reading unit 23 has been described. However, the present invention is not limited to such a case.

  For example, one or two reading units among the upper surface reading unit 21, the lower surface reading unit 22, and the side surface reading unit 23 may be provided, and the subject X can be moved from above by moving one reading unit. It may be possible to read from below and from the side. Furthermore, another side reading unit for reading the side surface opposite to the subject X may be provided at a position facing the side reading unit 23.

  Further, in the scanner device 1 according to the above-described embodiment, a case has been described in which the entire area of the subject X in the predetermined direction can be read by moving the work table 3 (stage 31) in the horizontal direction. Not limited to cases. For example, the work table (stage) may move in the vertical direction so that the entire area of the subject X in the predetermined direction can be read. If both the work table (stage) and the reading unit move, the subject can move. It may be possible to read the entire region in a predetermined direction of X.

  In the scanner device 1 according to the above embodiment, the upper surface reading unit 21 is brought into contact with and separated from the stage 31 by the first position adjusting unit 215, and the side surface reading unit 23 is moved by the second position adjusting unit 235. Although the case where it contacts / separates with respect to 31 was demonstrated, it is not restricted to such a case. For example, the optical system of each reading unit may include an automatic focus adjustment function (autofocus function) including a plurality of lenses, and each reading unit may flexibly respond to the distance from the subject X.

  In the scanner device 1 according to the above-described embodiment, the case where each of the light receiving elements 213, 223, and 233 is a CCD line sensor has been described. In the case of a CCD area sensor, it is possible to prevent the end side of the subject X from being distorted and read by selecting data of a predetermined line-shaped portion from the read data.

  Further, in the scanner device 1 according to the above-described embodiment, the case where the processing device 100 is separately provided has been described. However, the present invention is not limited to such a case, and the scanner device may include each component of the processing device.

  Further, in the scanner device 1 according to the above embodiment, the case where the rotation of the stage 31 is operated by the operation button 37 and the inclination of the stage 31 is operated by the operation units 313c and 314c of the respective angle adjusting units 313 and 314 has been described. However, it is not limited to such a case. For example, it may be possible to operate by automatic control by inputting a desired rotation angle or inclination angle to the input means of the processing apparatus. In such a case, each angle is controlled by providing detection means (rotation angle detection sensor, tilt angle detection sensor).

  Further, in the scanner device 1 according to the above-described embodiment, the case where the stage 31 is moved in the horizontal direction to read the side of the subject X, that is, the case where the side surface data is acquired has been described. However, the present invention is not limited to such a case. The stage 31 may be rotated to read the side of the subject X, that is, the side development data may be acquired. In addition, calculation processing may be performed so as to acquire accurate lateral development data based on the side data of the subject X. An example of such a case is shown in FIG.

  As illustrated in FIG. 13A, the side of the truncated cone-shaped subject X is read by the side surface reading unit 23 by rotating the stage 31. Then, when the data of the subject X read by the side surface reading unit 23 is simply imaged as side development data, a rectangular image is obtained as shown in FIG.

  Therefore, data obtained by moving the stage 31 in the horizontal direction and reading the side of the subject X, that is, side data, is acquired at a plurality of angles. Then, when the shape of the subject X is calculated from the plurality of side surface data, and the lateral expansion data is calculated (corrected) based on the calculated shape of the subject X, the discontinuous as shown in FIG. Since the side development data image or the continuous side development data image as shown in FIG. 13D can be acquired, the side development data having an accurate dimension can be acquired.

  In the scanner device 1 according to the above-described embodiment, the side of the subject X is read by the stage 31 moving in the horizontal direction, so that the horizontal end of the subject X can be prevented from being distorted and read. The edge side in the vertical direction of the subject X is distorted and read. However, the side data read at a predetermined position (predetermined angle) is calculated based on the side data read from a different angle by rotating the stage 31 in order to prevent the end side in the vertical direction of the subject X from being distorted and read. (Correction) may be performed.

  In such a case, for example, first, the shape of the subject X is calculated based on a plurality of side data obtained by reading the sides of the subject X from a plurality of angles. Then, the side data read at a predetermined position is calculated according to the distance between each part of the subject X and the side reader 23. Specifically, the data of the part of the subject X far from the reference distance is calculated so as to increase, and the data of the part of the subject X close to the reference distance is calculated to be small.

  Thus, when the side of the subject X is read by moving the stage 31 in the horizontal direction, not only the horizontal end of the subject X can be prevented from being distorted, but also the end side of the subject X in the vertical direction can be prevented. Can be prevented from being distorted. Therefore, it is possible to measure an accurate dimension from the acquired data.

  The scanner device according to the present invention may read a subject that is easy to roll, for example, while being supported by a support made of wire or resin.
