Conventionally, in this type of mounting fixture, a housing with an emergency stop switch attached, a back support part that supports the mobile terminal from the back side, an upper base fixing part that fixes the upper base of the mobile terminal from the upper side, and a mobile terminal There is a mounting device provided with a lower sole fixing portion that fixes the lower sole from below (see Patent Document 1).

Japanese Patent No. 6218973

By the way, the mounting device described in Patent Document 1 fixes the upper base and the lower base of the mobile terminal by the upper base fixing part and the lower base fixing part, respectively. Therefore, it is necessary to design the distance between the upper base fixing portion and the lower base fixing portion according to the length from the upper base to the lower base of the mobile terminal. Mobile terminals come in various sizes, and the mounting fixture described in Patent Document 1 cannot be attached to mobile terminals that do not match in size, and the mobile terminals that can be attached are limited.

The present invention has been made in order to solve these problems, and its main purpose is to easily attach emergency stop switches of production machines to portable terminals of various sizes used as control terminals for production machines such as robots. To provide an emergency stop switch mounting device capable of being mounted on a vehicle and ensuring safety.

The first means for solving the above problems is
An attachment tool for attaching an emergency stop switch of a production machine to a rectangular plate-shaped portable terminal used as an operation terminal of the production machine,
a back portion formed in a plate shape and arranged on the back side of the mobile terminal;
a contact part connected to the back part and brought into contact with two side surfaces of the mobile terminal at one corner of the mobile terminal;
an adhesive portion provided on the back surface portion and adhered to the back surface of the mobile terminal;
an installation portion connected to the contact portion and installed so that the emergency stop switch is operated from the front side of the mobile terminal;
Prepare.

According to the above configuration, the rear portion is formed in a plate shape and arranged on the rear side of a rectangular plate-shaped portable terminal used as an operation terminal of a production machine. The abutting part is connected to the back part and abuts against two side surfaces of the mobile terminal at one corner of the rectangular plate-shaped mobile terminal. Therefore, the mobile terminal can be easily positioned with respect to the abutment part and the mounting device by bringing the two side surfaces of the corners of the mobile terminal into contact with the abutment part, and the mobile terminal can be carried on the adhesive part at an inappropriate position. It is possible to suppress sticking of the back surface of the terminal. Therefore, it is possible to suppress the repetition of peeling off the back surface of the mobile terminal from the adhesive part and again sticking the back surface of the mobile terminal to the adhesive part, and suppress the decrease in the adhesive strength of the adhesive part. can. As a result, when it is necessary to press the emergency stop switch of the production machine, it is possible to prevent the mounting device from being detached from the portable terminal, thereby ensuring safety. The adhesive portion is provided on the rear surface portion and adheres to the rear surface of the mobile terminal. Therefore, the back surface of the positioned mobile terminal can be adhered with the adhesive member, and the mobile terminal can be fixed to the back surface portion. And the back surface of a portable terminal can be supported by the back surface part. Production machines are machines that are directly involved in the production and output of products in various industries, and include robots, machine tools, and the like.

The installation portion is connected to the contact portion, and an emergency stop switch is installed in the installation portion so that it can be operated from the front side of the portable terminal. Therefore, the emergency stop switch can be installed in the installation portion, and the user can operate the emergency stop switch from the front side of the portable terminal. Therefore, the emergency stop switch can be attached to the mobile terminal simply by aligning one corner of the mobile terminal with the contact portion and fixing at least a part of the back surface of the mobile terminal to the back surface portion with the adhesive portion. That is, the mounting fixture does not restrict the positions of the remaining three corners of the mobile device. Therefore, the emergency stop switch can be easily attached to mobile terminals of various sizes. Moreover, the configuration for attaching the emergency stop switch to the portable terminal does not include any mechanical moving parts. For this reason, it is possible to suppress the occurrence of failures in the fixture for mounting the emergency stop switch, which requires high reliability.

Here, a configuration is conceivable in which the state of the emergency stop switch attached to the mobile terminal by the attachment tool is transmitted to the controlled object via the mobile terminal. In such a configuration, the safety of the mobile terminal may not be ensured, and there is a possibility that the controlled object cannot be reliably stopped in an emergency. In this respect, the mounting fixture of the present application only requires that the emergency stop switch can be mounted on the portable terminal, and does not need to be relayed between the emergency stop switch and the portable terminal, so that safety can be ensured.

In a second means, a recess is formed in the back portion adjacent to the abutment portion. According to such a configuration, when the two side surfaces of the corners of the mobile terminal are brought into contact with the abutting portions, the corners of the mobile terminal can be released into the depressions and the mobile terminal can be tilted. Therefore, it is possible to prevent the rear surface of the mobile terminal from contacting the adhesive portion before the two side surfaces of the corners of the mobile terminal are brought into contact with the contact portion. Therefore, it is possible to suppress failures and redoes in aligning and fixing the position of the mobile terminal with respect to the mounting fixture, and it is possible to suppress a decrease in the adhesive force of the adhesive portion. Furthermore, when a convex portion is formed by a lens of a camera or the like in the corner of the rear surface of the portable terminal, the convex portion can be released into the recess.

In the third means, a hole is formed at a position adjacent to the contact portion on the back portion. With such a configuration as well, when the two side surfaces of the corners of the mobile terminal are brought into contact with the abutting portions, the corners of the mobile terminal can be released into the holes and the mobile terminal can be tilted. Therefore, it is possible to suppress failures and redoes in aligning and fixing the position of the mobile terminal with respect to the mounting fixture, and it is possible to suppress a decrease in the adhesive force of the adhesive portion. Furthermore, when a convex portion is formed by a lens of a camera or the like at the corner of the rear surface of the mobile terminal, the convex portion can be released into the hole. Moreover, it is possible to take a picture with a camera lens through the hole.

If the back part arranged on the back side of the mobile terminal is too small, when the user supports the mobile terminal with his or her hand, there is a risk that he/she will support only the back of the mobile terminal and not the back part of the mounting device. . Even in this case, if the adhesive strength of the adhesive portion is sufficient, the mounting fixture will not come off from the portable terminal when the user presses the emergency stop switch. However, if the adhesive force of the adhesive portion is reduced, there is a risk that the mounting fixture will come off from the portable terminal when the user presses the emergency stop switch.

In this regard, in the fourth means, the length of the back portion in the length direction of the short side of the rectangular plate-shaped portable terminal is not less than half of the short side and not more than the full length. According to such a configuration, when the user supports the mobile terminal by hand, there is a high possibility that the user will support not only the back surface of the mobile terminal but also the back surface of the attachment tool. Therefore, when the user presses the emergency stop switch, it is possible to prevent the mounting fixture from being removed from the mobile terminal, thereby ensuring greater safety. In addition, when the left hand supports the heavy side of the portable terminal to which the mounting fixture is attached, it is unlikely that the left hand supporting the mounting fixture is released and the left hand presses the emergency stop switch. Furthermore, since the length of the back portion in the length direction of the short side of the portable terminal is equal to or less than the total length of the short side, it is possible to prevent the back portion from becoming unnecessarily large.

In a fifth measure, the profile of said mounting device is symmetrical. According to such a configuration, the attachment tool can be attached to the upper right corner of the mobile terminal in the same manner as the attachment tool is attached to the upper left corner of the mobile terminal, for example. Therefore, the mounting device for the emergency stop switch can be used by both right-handed and left-handed users.

In the sixth means, the back portion includes a first surface portion extending along the long sides of the rectangular plate-shaped portable terminal and a second surface portion extending along the short sides. According to such a configuration, when the user supports the portable terminal by hand, it is highly likely that the user will support either the first surface portion or the second surface portion by hand. Therefore, even if the emergency stop switch is pushed with a force greater than expected in an emergency, the emergency stop switch can be prevented from coming off together with the mounting fixture, and the emergency stop switch can be reliably pushed easily.

In the seventh means, the adhesive section is formed of double-sided tape. According to such a configuration, the adhesive portion can be easily formed, and replacement becomes easy when the adhesive strength of the adhesive portion is lowered.

In the eighth means, the adhesive portion is made of a gel sheet. According to such a configuration, when the adhesive force of the adhesive portion is lowered, the adhesive force can be restored by removing dust or the like on the surface of the gel sheet. In addition, it is desirable to combine the fourth means and the seventh means in preparation for the case where the adhesive strength of the adhesive portion is lowered.

An embodiment embodied in a mounting device for mounting an emergency stop box of a robot to a tablet terminal used as an operation terminal of a robot (production machine) will be described below with reference to the drawings.

As shown in FIGS. 1 and 2, the mounting device 10 includes a back surface portion 20, contact portions 31 and 35, double-sided tapes 51-53, and an installation portion . The mounting fixture 10 is integrally formed of resin, for example, except for the double-sided tapes 51-53. An emergency stop box 60 is installed in the installation section 40 .

The emergency stop box 60 includes a main body 61, an emergency stop switch 63, a stop control section (not shown), a cable connection section 65, and the like. One end of a cable (not shown) is connected to the cable connection portion 65, and the other end of the cable is connected to the control device of the robot (or machine tool). The stop control unit periodically transmits a predetermined signal to the control device via the cable, for example, during normal operation. The control device determines that the robot is normal based on the regular reception of the predetermined signal. When the user presses the emergency stop switch 63, transmission of the predetermined signal is cut off. The control device determines that an abnormality has occurred in the robot based on the fact that the predetermined signal is not received periodically, and brings the robot to an emergency stop.

The back portion 20 is formed in a plate shape of an isosceles right triangle (substantially triangular). As shown in FIG. 3, in the lengthwise direction of the short sides of the tablet terminal 70, the length of the back surface portion 20 is equal to or longer than half of the short sides and equal to or shorter than the full length. Attachment portions 21 to 23 to which circular double-sided tapes 51 to 53 are attached are formed on the back portion 20 . The double-sided tapes 51 to 53 (adhesive portions) are disc-shaped and have a predetermined thickness. The double-sided tapes 51-53 have the same size and shape. The sticking portions 21-23 are circular recesses having the same diameter as the double-sided tapes 51-53. The depth of the sticking portions 21-23 is shallower than the thickness of the double-sided tapes 51-53. That is, the surfaces of the double-sided tapes 51 to 53 protrude from the surface of the back surface portion 20. As shown in FIG.

Then, the double-sided tapes 51 to 53 are adhered to the back surface of the tablet terminal 70 . As shown in FIG. 3 , when the mounting fixture 10 is attached to the tablet terminal 70 , the back surface portion 20 is arranged on the back side of the tablet terminal 70 . It should be noted that the user replaces the double-faced tapes 51 to 53 with new ones when removing the mounting tool 10 from the tablet terminal 70 and then mounting it again.

As is well known, the tablet terminal 70 (portable terminal) is a kind of lightweight PC (Personal Computer) shaped like a rectangular plate. The tablet terminal 70 includes a rectangular plate-shaped housing 71, a display 72, buttons 73, a camera (not shown), and the like. The display 72 is configured by a liquid crystal display device or the like, and has a touch panel type input interface. The tablet terminal 70 has a wireless communication function, and performs communication and Internet connection via a wireless LAN (Local Area Network) or a mobile phone line. By installing application software (program) for operating the robot in the tablet terminal 70, the tablet terminal 70 functions as a robot controller. The tablet terminal 70 wirelessly transmits (sends) an operation signal corresponding to the user's operation to the control device of the robot. Note that the tablet terminal 70 may wire-transmit the operation signal to the control device of the robot.

Abutting portions 31 and 35 are connected to right-angled portions (corners) of the back portion 20 . The surfaces of the contact portions 31 and 35 protrude from the surface of the back portion 20 . That is, the contact portions 31 and 35 respectively have wall portions 32 and 36 (guide portions) rising vertically from the back surface portion 20 . The wall portion 32 and the wall portion 36 are connected vertically. A depression 24 is formed in the rear portion 20 at a position adjacent to the contact portions 31 and 35 . The contour of the recess 24 is triangular. As shown in FIG. 3, the tablet terminal 70 has four corners 75-78. The contact portions 31 and 35 are in contact with the side surfaces 78a and 78b of the tablet terminal 70 at the corners 78 of the tablet terminal 70, respectively. That is, the walls 32 and 36 function as guides when positioning the tablet terminal 70 with respect to the mounting fixture 10 . Therefore, the tablet terminal 70 can be easily positioned with respect to the mounting fixture 10, and the back surface of the tablet terminal 70 can be prevented from sticking to the double-sided tapes 51 to 53 at inappropriate positions. Therefore, it is possible to suppress the repetition of peeling off the back surface of the tablet terminal 70 from the double-sided tapes 51 to 53 and adhering the back surface of the tablet terminal 70 to the double-sided tapes 51 to 53 again. A decrease in adhesive strength can be suppressed. As a result, when it is necessary to press the emergency stop switch 63, it is possible to prevent the attachment tool 10 from coming off the tablet terminal 70, thereby ensuring safety. In the back portion 20, the portion extending from the contact portion 35 to the back surface of the double-sided tape 51 corresponds to the first surface portion, and the portion extending from the contact portion 31 to the back surface of the double-sided tape 53 corresponds to the second surface portion.

An installation portion 40 is connected to the contact portions 31 and 35 . The installation portion 40 is formed in a disc shape. The installation portion 40 has an annular outer wall portion 41 . The outer wall portion 41 is fitted with the lower portion of the main body 61 of the emergency stop box 60 . A cylindrical protrusion 42 is formed in a portion of the installation portion 40 surrounded by the outer wall portion 41 . A rectangular concave portion 43 is formed in the convex portion 42 . The recess 43 is formed in a size and shape corresponding to a hook (not shown) attached to the bottom of the emergency stop box 60 . Two through holes 46 are formed in the installation portion 40 . Screws are inserted through the through-holes 46 when the emergency stop box 60 is fixed to the installation portion 40 . Then, the installation portion 40 and the emergency stop box 60 are fastened with screws. As shown in FIG. 1 , an emergency stop switch 63 is installed in the installation section 40 so that it can be operated from the front side of the tablet terminal 70 . FIG. 4 is a perspective view showing a state in which the attachment tool 10 is attached to the tablet terminal 70 from the rear side.

The external shape of the attachment tool 10 having the above configuration is bilaterally symmetrical. Specifically, the external shape of the mounting fixture 10 having the above configuration is symmetrical with respect to a predetermined plane perpendicular to the back surface portion 20 . The predetermined plane is a plane that passes through the center of the sticking portion 22 and the center of the installation portion 40 and is perpendicular to the back portion 20 . With such a configuration, the attachment tool 10 can be attached to the upper right corner 75 of the tablet terminal 70 in the same manner as the attachment tool 10 is attached to the upper left corner 78 of the tablet terminal 70 .

Next, referring to FIG. 5, a manner of positioning the corners 78 of the tablet terminal 70 on the walls 32 and 36 (guides) will be described.

When the back surface 70a of the tablet terminal 70 contacts the double-sided tape 52 (51, 53) before the side surface 78b (78a) of the corner 78 of the tablet terminal 70 contacts the wall part 36 (32), the tablet terminal 70 is attached. The instrument 10 is fixed in an improper position. In that case, it is necessary to peel off the back surface 70a of the tablet terminal 70 from the double-sided tape 52 (51, 53) and redo the positioning of the tablet terminal 70 and the mounting fixture 10, and the adhesive force of the double-sided tape 52 (51, 53) may decrease.

In this regard, a depression 24 is formed in the rear portion 20 at a position adjacent to the contact portion 35 (31). For this reason, by allowing the corners 78 of the tablet terminal 70 to escape into the recesses 24 of the back surface portion 20, the tablet terminal 70 can be tilted more easily with respect to the back surface portion 20 than when the recesses 24 are not formed in the back surface portion 20. Become. Thereby, the back surface 70a of the tablet terminal 70 can be prevented from coming into contact with the double-sided tape 52 (51, 53). Moreover, even if the back surface 70a of the tablet terminal 70 contacts the double-sided tape 52 (51, 53), the contact area can be reduced.

Then, while the side surface 78b (78a) of the corner 78 of the tablet terminal 70 and the wall portion 36 (32) are in contact with each other, the tablet terminal 70 is returned parallel to the back surface portion 20, and the back surface of the tablet terminal 70 is 70a is adhered to the double-sided tape 52 (51, 53). Thereby, the attachment tool 10 can be attached to the tablet terminal 70 .

It should be noted that when a convex portion (not shown) is formed by a camera lens on the back surface of the corner 78 of the tablet terminal 70 , the convex portion can escape to the recess 24 . As a result, it is possible to prevent the protrusions from interfering with the fixation of the back surface 70a of the tablet terminal 70 and the double-sided tape 52 (51, 53).

The embodiment detailed above has the following advantages.

- The back surface part 20 is formed in plate shape, and is arrange|positioned at the back surface 70a side of the tablet terminal 70 of rectangular plate shape. The contact portions 31 and 35 are connected to the back portion 20 and are brought into contact with two side surfaces 78 a and 78 b of the tablet terminal 70 at one corner 78 of the tablet terminal 70 having a rectangular plate shape. Therefore, the two side surfaces 78a and 78b of the corner 78 of the tablet terminal 70 can be brought into contact with the contact portions 31 and 35 to position the tablet terminal 70 with respect to the contact portions 31 and 35 and the mounting fixture 10. can. The double-faced tapes 51 to 53 are provided on the back surface portion 20 and adhered to the back surface 70 a of the tablet terminal 70 . Therefore, the tablet terminal 70 can be fixed to the back surface portion 20 by adhering the back surface 70 a of the positioned tablet terminal 70 with the double-sided tapes 51 to 53 . Then, the back surface 70 a of the tablet terminal 70 can be supported by the back surface portion 20 .

The installation portion 40 is connected to the contact portions 31 and 35, and the emergency stop switch 63 is installed in the installation portion 40 so that it can be operated from the front side of the tablet terminal 70. Therefore, the emergency stop switch 63 (emergency stop box 60 ) can be installed in the installation section 40 , and the user can operate the emergency stop switch 63 from the front side of the tablet terminal 70 . In addition, since the mounting fixture 10 and the emergency stop switch 63 do not interfere with the display 72, it is possible to suppress deterioration in operability of the tablet terminal 70 and erroneous operation. Therefore, only by aligning one corner 78 of the tablet terminal 70 with the abutting portions 31 and 35 and fixing at least a part of the back surface 70a of the tablet terminal 70 to the back surface portion 20 with the double-sided tapes 51 to 53, the tablet terminal can be An emergency stop switch 63 can be attached to 70 . That is, the mounting device 10 does not limit the positions of the remaining three corners 75-77 of the tablet terminal 70. FIG. Therefore, the emergency stop switch 63 can be easily attached to tablet terminals 70 of various sizes. Moreover, the configuration for attaching the emergency stop switch 63 to the tablet terminal 70 does not include any mechanical movable part. Therefore, it is possible to suppress the occurrence of failures in the mounting fixture 10 for the emergency stop switch 63, which requires high reliability.

- A configuration is conceivable in which the state of the emergency stop switch 63 attached to the tablet terminal 70 by the attachment tool 10 is transmitted to the robot via the tablet terminal 70 . With such a configuration, the safety of the tablet terminal 70 may not be ensured, and the robot may not be reliably stopped in an emergency. In this respect, the mounting fixture 10 only needs to be able to mount the emergency stop switch 63 to the tablet terminal 70, and there is no need to relay the emergency stop switch 63 and the tablet terminal 70, so safety can be ensured. .

- A depression 24 is formed at a position adjacent to the contact portions 31 and 35 in the back portion 20 . According to such a configuration, when the two side surfaces 78a and 78b of the corner 78 of the tablet terminal 70 are brought into contact with the contact portions 31 and 35, the corner 78 of the tablet terminal 70 is released into the depression 24 and the tablet terminal 70 is tilted. be able to. Therefore, before the two side surfaces 78a and 78b of the corner 78 of the tablet terminal 70 are brought into contact with the contact portions 31 and 35, the rear surface 70a of the tablet terminal 70 is prevented from contacting the double-sided tapes 51 to 53. can be done. Therefore, it is possible to suppress failures and redoes in aligning and fixing the tablet terminal 70 with respect to the mounting device 10, and it is possible to suppress a decrease in the adhesive strength of the double-sided tapes 51-53. Furthermore, when a convex portion is formed on the corner 78 of the rear surface 70 a of the tablet terminal 70 by a camera lens or the like, the convex portion can be released into the recess 24 .

- In the length direction of the short side of the rectangular plate-shaped tablet terminal 70, the length of the back portion 20 is equal to or more than half of the short side and equal to or less than the full length. According to such a configuration, when the user supports the tablet terminal 70 by hand, there is a high possibility that not only the back surface 70a of the tablet terminal 70 but also the back surface portion 20 of the mounting fixture 10 will be supported by the hand. Therefore, when the user presses the emergency stop switch 63, it is possible to prevent the attachment tool 10 from coming off the tablet terminal 70, thereby ensuring greater safety. It should be noted that if the left hand side of the tablet terminal 70, which is heavy due to the mounting fixture 10 being attached, is supported by the left hand, it is unlikely that the left hand supporting the mounting fixture 10 will be released and the emergency stop switch 63 will be pressed with the left hand. . Furthermore, since the length of the back portion 20 in the length direction of the short side of the tablet terminal 70 is equal to or less than the total length of the short side, it is possible to suppress the back portion 20 from becoming unnecessarily large.

- The profile of the mounting device 10 is symmetrical with respect to a plane perpendicular to the back surface 20; With such a configuration, the attachment tool 10 can be attached to the upper right corner 75 of the tablet terminal 70 in the same manner as the attachment tool 10 is attached to the upper left corner 78 of the tablet terminal 70 . Therefore, whether the user is right-handed or left-handed, the mounting device 10 for the emergency stop switch 63 can be used.

- The back surface portion 20 includes a first surface portion extending along the long side of the rectangular plate-shaped tablet terminal 70 and a second surface portion extending along the short side. According to such a configuration, when the user supports the tablet terminal 70 by hand, it is highly likely that the user will support either the first surface portion or the second surface portion by hand. Therefore, even if the emergency stop switch 63 is pressed with a force greater than expected in an emergency, it is possible to prevent the emergency stop switch 63 from falling off together with the mounting fixture 10, and the emergency stop switch 63 can be reliably pushed. .

- The adhesive portion to be adhered to the back surface 70a of the tablet terminal 70 is formed of double-sided tapes 51-53. With such a configuration, the adhesive portion can be easily formed, and the replacement of the double-faced tapes 51 to 53 becomes easy when the adhesive force is lowered.

It should be noted that the above embodiment can be modified as follows. Parts that are the same as those in the above embodiment are denoted by the same reference numerals, and descriptions thereof are omitted.

- As shown in FIG. 6, the recesses 24 can also be made deeper compared to FIG. In this case, the back surface 70a of the tablet terminal 70 contacts the opening end 24a of the recess 24 before the back surface 70a contacts the double-sided tape 52 (51, 53). Therefore, it is possible to further prevent the back surface 70a of the tablet terminal 70 from coming into contact with the double-sided tape 52 (51, 53).

- As shown in FIG. 7, holes 124 may be formed in the rear portion 20 in place of the recesses 24 . That is, holes 124 may be formed at positions adjacent to the contact portions 31 and 35 on the back portion 20 . Even with this configuration, when the two side surfaces 78a and 78b of the corner 78 of the tablet terminal 70 are brought into contact with the contact portions 31 and 35, the corner 78 of the tablet terminal 70 can be released into the hole 124 and the tablet terminal 70 can be tilted. can be done. Therefore, it is possible to suppress failures and redoes in aligning and fixing the tablet terminal 70 with respect to the mounting device 10, and it is possible to suppress a decrease in the adhesive strength of the double-sided tapes 51-53. Furthermore, when a convex portion is formed by a camera lens at the corner 78 of the back surface 70 a of the tablet terminal 70 , the convex portion can escape to the hole 124 . Moreover, through the hole 124, a photograph can be taken with a camera lens. It should be noted that the hole 124 does not necessarily have to be triangular, and may be square or polygonal.

- As shown in FIG. 8, the recesses 24 and the holes 124 may not be formed in the rear portion 20 . In this case, as shown in FIG. 9, before the side surface 78b (78a) of the corner 78 of the tablet terminal 70 abuts against the wall portion 36 (32), the back surface 70a of the tablet terminal 70 and the double-sided tape 52 (51, 53) are attached to each other. ) is slightly easier to come into contact with. Therefore, it is desirable to form the recesses 24 or holes 124 in the back portion 20 .

- As shown in FIG. 10, the back surface part 20 does not necessarily have to be in the shape of a right-angled isosceles triangle, and may be in the shape of a quadrangle or a polygon. Also, the outer shape of the depression 24 does not necessarily have to be triangular, and may be square or polygonal. In the figure, in the back surface portion 20, the portion extending from the contact portion 35 beyond the sticking portion 21 corresponds to the first surface portion, and the portion extending from the contact portion 31 beyond the sticking portion 23 corresponds to the second surface portion. .

- As shown in FIG. 11, the sticking portions 21 to 23 may be omitted from the back portion 20. FIG. Then, a double-sided tape having a size obtained by adding the double-sided tapes 51 to 53 can be attached to the back surface portion 20 .

- As shown in FIG. 12, in the length direction of the short side of the rectangular plate-shaped tablet terminal 70, the length of the back portion 20 can be less than half of the short side. Then, a double-sided tape can be attached to the back portion 20 . However, if the back surface portion 20 arranged on the back surface 70a side of the tablet terminal 70 is too small, when the user supports the tablet terminal 70 by hand, only the back surface 70a of the tablet terminal 70 is supported by the hand, and the back surface of the mounting fixture 10 is reduced. There is a risk that the part 20 cannot be supported by hand. Even in this case, if the adhesive force of the double-sided tape is sufficient, the attachment tool 10 will not come off from the tablet terminal 70 when the user presses the emergency stop switch 63 . However, if the adhesive force of the double-sided tape is reduced, there is a risk that the attachment tool 10 will come off from the tablet terminal 70 when the user presses the emergency stop switch 63 . Therefore, in the length direction of the short sides of the rectangular plate-shaped tablet terminal 70, it is desirable that the length of the back surface portion 20 is not less than half of the short sides and not more than the full length. In addition, in the length direction of the short sides of the rectangular plate-shaped tablet terminal 70, the length of the back portion 20 can be made longer than the total length of the short sides.
