In order to suppress this, the third shaft 8c3 of the first jig 8 and the second jig 9 are arranged so that the distance between the display area 2a of the monitor main body 2 and the transparent portion 10b of the monitor case 3 is the narrowest. It is engaged with the recess 9p. At this time, the viewing angle V, the arrangement position of the third axis 8c3, and the like are set in advance so that the display area 2a of the monitor main body 2 is arranged within the viewing angle V of the monitor 1. FIG.

When tilting the monitor main body 2 forward, tilting the monitor main body 2 forward about the first axis 8c1 causes the monitor main body 2 to move toward the X axis in the monitor case 3, as shown in FIG. 14(a). Since it is located on the − side and is located closest to the Z axis − side, the Z axis − side portion of the display area 2 a of the monitor main body 2 is out of the viewing angle V of the monitor 1 .

When tilted forward about the third axis 8c3, as shown in FIG. 14(b), the monitor main body 2 is positioned at the most + side position of the X axis in the monitor case 3, and the Z axis - Therefore, the display area 2a of the monitor main body 2 on the Z-axis - side is outside the viewing angle V of the monitor 1, and the end of the monitor main body 2 on the Z-axis + side is outside the monitor case. 3 comes into contact with the cover portion 10. Therefore, in this embodiment, as shown in FIG. 14(c), it is arranged on the X-axis - side with respect to the first axis 8c1 and on the X-axis + side with respect to the third axis 8c3. The monitor main body 2 is tilted forward about the second axis 8c2 arranged on the Z-axis - side with respect to the first axis 8c1 and the third axis 8c3.

As a result, compared to the case where the monitor main body 2 is tilted forward about the first axis 8c1, the monitor main body 2 is positioned on the + side of the Z axis and on the + side of the X axis. , the monitor body 2 can be tilted forward. Also, compared to the case where the monitor body 2 is tilted forward about the third axis 8c3, when the monitor body 2 is positioned on the + side of the Z axis and on the - side of the X axis, The monitor body 2 can be tilted forward.

At this time, when the monitor main body 2 is tilted forward within a preset tilting range, the display of the monitor main body 2 is prevented without the end of the monitor main body 2 on the Z-axis + side coming into contact with the cover portion 10 of the monitor case 3 . The viewing angle V, the arrangement position of the second axis 8c2, and the like are set in advance so that the area 2a is arranged within the viewing angle V of the monitor 1. FIG. Therefore, the monitor body 2 is arranged so that the display area 2a of the monitor body 2 is arranged within the viewing angle V of the monitor 1 without the end of the monitor body 2 on the Z-axis + side coming into contact with the cover portion 10 of the monitor case 3. The main body 2 can be tilted forward.

On the other hand, when the monitor body 2 is tilted backward, tilting the monitor body 2 backward about the second axis 8c2 causes the monitor body 2 to move toward the Z axis in the monitor case 3, as shown in FIG. 15(a). Since it is arranged at the + side position, the Z-axis + side portion of the display area 2 a of the monitor main body 2 is out of the viewing angle V of the monitor 1 .

Further, when the monitor main body 2 is tilted backward about the third axis 8c3, the monitor main body 2 is located at the position closest to the X-axis + side in the monitor case 3, and , the display area 2a of the monitor body 2 on the +Z-axis side is outside the viewing angle V of the monitor 1, and the edge of the monitor body 2 on the -Z-axis side. part touches the cover part 10 of the monitor case 3. Therefore, in this embodiment, as shown in FIG. The monitor main body 2 is tilted backward about the first axis 8c1 arranged on the Z-axis + side with respect to the axis 8c3.

As a result, compared to the case where the monitor main body 2 is tilted backward about the second axis 8c2 or the third axis 8c3, the monitor main body 2 is positioned on the Z-axis - side and on the X-axis - side. The monitor main body 2 can be tilted backward in a state of arranging it at the position.

At this time, when the monitor main body 2 is tilted backward within a preset tilting range, the display of the monitor main body 2 is prevented without the end of the monitor main body 2 on the Z-axis - side coming into contact with the cover portion 10 of the monitor case 3 . The viewing angle V, the arrangement position of the first axis 8c1, and the like are set in advance such that the area 2a is arranged within the viewing angle V of the monitor 1. FIG. Therefore, the monitor body 2 is arranged so that the display area 2a of the monitor body 2 is arranged within the viewing angle V of the monitor 1 without the Z-axis side end of the monitor body 2 contacting the cover portion 10 of the monitor case 3. The main body 2 can be tilted backward.

In addition, in a state in which any one of the first shaft 8c1, the second shaft 8c2 and the third shaft 8c3 of the first jig 8 is engaged with the concave portion 9p of the second jig 9, the monitor As long as the main body 2 can be tilted within the monitor case 3, the shape and arrangement of the projecting portion 8b of the first jig 8 and the arm portion 9b of the second jig 9 are not limited.

Next, the procedure for adjusting the position of the monitor main body 2 in the X-axis direction in the monitor 1 of this embodiment will be described. FIG. 16 is a perspective view of the monitor of this embodiment as seen from above, showing a state in which the monitor main body is arranged on the front side.

If the distance between the display area 2a of the monitor main body 2 and the transmissive portion 10b of the monitor case 3 is large, the brightness of the image emitted from the monitor main body 2 decreases before reaching the transmissive portion 10b of the monitor case 3. and the resulting increase in the influence of diffused reflection reduces visibility. Therefore, for example, as shown in FIG. 5, when the display area 2a of the monitor main body 2 is arranged substantially parallel to the YZ plane, first, the second concave portion 9n of the first projecting portion 9d of the second jig 9 is The edge of the Z-axis minus side of the first through hole 11d of the partition 11b of the monitor case 3 is inserted into and hooked.

At this time, as shown in FIG. 16, the X-axis + side surface of the second portion 9k of the first projecting portion 9d of the second jig 9 and the X-axis − side of the partition portion 11b of the monitor case 3 are aligned. The surfaces are substantially in surface contact with each other. At the same time, the surface of the second projecting portion 9f of the second jig 9 on the +Y-axis side and the surface of the projecting portion 11g of the partition portion 11b on the -Y-axis side are substantially in surface contact. Thereby, the positions of the second jig 9 in the X-axis direction and the Y-axis direction are fixed.

In this state, the bolt 15 is screwed into the second screw hole 11j of the partition portion 11b. Further, the bolt 17 is passed through the third through hole 11h of the projecting portion 11g of the partition portion 11b, and the bolt 17 is screwed into the screw hole 9g of the second projecting portion 9f of the second jig 9. Thereby, the position of the second jig 9 in the Z-axis direction is fixed.

When the second jig 9 is fixed to the partition portion 11b of the monitor case 3 using the second concave portion 9n of the first projecting portion 9d of the second jig 9, the second jig Compared to the case where the second jig 9 is fixed to the partition portion 11b of the monitor case 3 using the first concave portion 9m of the first projecting portion 9d of the monitor body 2, the monitor main body 2 is arranged on the X-axis + side. can do. Therefore, it is possible to suppress the decrease in the brightness of the image reaching the transmissive portion 10b of the monitor case 3 and the effect of diffused reflection caused thereby, and as a result, the visibility can be improved.

On the other hand, when tilting the monitor body 2 forward or backward, as described above, if the monitor body 2 is placed on the + side of the X axis, the end of the monitor body 2 on the - side of the Z axis or the end on the + side of the Z axis contacts the cover portion 10 of the monitor case 3. Therefore, for example, when tilting the monitor main body 2 forward or backward, first, the partition portion 11b of the monitor case 3 is inserted into the first concave portion 9m of the first projecting portion 9d of the second jig 9. The edge of the hole 11d on the Z-axis side is inserted and hooked.

At this time, as shown in FIG. 4, the X-axis − side surface of the first portion 9j of the first projecting portion 9d of the second jig 9 and the X-axis + side of the partition portion 11b of the monitor case 3 are aligned. , and the surface of the body portion 9c of the second jig 9 on the negative side of the X-axis and the surface of the partition portion 11b on the positive side of the X-axis are substantially in surface contact with each other. At the same time, the second projecting portion 9f of the second jig 9 is passed through the second through hole 11e of the partition portion 11b. Thereby, the positions of the second jig 9 in the X-axis direction and the Y-axis direction are fixed.

In this state, the bolt 15 is screwed into the second screw hole 11j of the partition portion 11b. Also, a bolt 16 is passed through the through hole 9e of the second jig 9, and the bolt 16 is screwed into the first screw hole 11f of the partition portion 11b. Thereby, the position of the second jig 9 in the Z-axis direction is fixed.

Here, when the monitor main body 2 is tilted at a preset maximum tilting angle, the monitor main body 2 does not contact the cover portion 10 of the monitor case 3, and the display area 2a of the monitor main body 2 and the monitor case 3 are separated. The arrangement position of the first concave portion 9m of the second jig 9 and the like are set in advance such that the distance between the cover portion 10 and the transmitting portion 10b is the narrowest.

Therefore, when the second jig 9 is fixed to the partition portion 11b of the monitor case 3 using the first concave portion 9m of the first projecting portion 9d of the second jig 9, the display area of the monitor main body 2 is The monitor body 2 can be tilted while suppressing the monitor body 2 from contacting the cover part 10 of the monitor case 3 in a state where the distance between the monitor body 2a and the transmission part 10b of the monitor case 3 is made as narrow as possible. . Therefore, compared with the monitor of Patent Document 1, it is possible to suppress the deterioration of the brightness of the image reaching the transmissive portion 10b of the monitor case 3 and the effect of diffused reflection caused thereby, thereby improving the visibility.

Next, a procedure for opening and closing the monitor main body 2 in the monitor 1 of this embodiment will be described.

Next, the bolt 16 passed through the through hole 9e of the second jig 9 and the screw hole 11f of the partition portion 11b of the monitor case 3 is loosened.

By rotating the monitor main body 2 around the Z-axis around the first concave portion 9m of the first projecting portion 9d of the second jig 9, the monitor main body 2 can be opened. At this time, when the monitor body 2 is opened at a preset angle, as shown in FIG. 18, the peripheral surface of the first recess 9m is Z-axis-- It is preferable that the opening angle of the monitor main body 2 is limited by contacting the side portion. As a result, the monitor main body 2 can be stabilized when, for example, the monitor main body 2 is opened and the inside of the monitor 1 is inspected.
