[0003] [Patent Document 1] Patent Publication No. 2021-057725 Summary of the Invention [Problem to be solved by the invention]

[0004] The loop antenna is mounted on one surface of the antenna board. The antenna board is fixed to the bezel by a metal screw at a position inside the bezel facing the front surface of the bezel. At this time, the screw penetrates the antenna board. Therefore, when viewed from a direction perpendicular to the arrangement direction of the front surface of the bezel and the antenna board, a part of the screw is located between the medium and the antenna. However, when a part of the screw is located between the medium and the antenna, there is a problem that the screw affects communication between the medium and the antenna when the information processing device is in use.

[0005] In view of the above problems, an object of the present invention is to provide an information processing device that can reduce the influence of screws on communication between a medium and an antenna, even when an antenna board is fixed to a case with metal screws. [Means for solving the problem]

[0006] In order to solve the above problem, one aspect of the present invention is an information processing device that communicates with a medium non-contact, comprising a case having a first surface to which the medium can be brought close, an antenna board facing the first surface inside the case and having an antenna that communicates with the medium, and a metal screw that is fastened into a screw hole formed in the case to fix the antenna board to the case, wherein in an arrangement direction in which the first surface and the antenna board are arranged, if the side on which the first surface is located is defined as a first side and the side on which the antenna board is located is defined as a second side, the screw is located on the second side of the antenna board and does not overlap with the antenna board when viewed from a direction perpendicular to the arrangement direction.

[0007] According to this aspect, the screw is located on the second side of the antenna substrate and does not overlap with the antenna substrate when viewed from a direction perpendicular to the arrangement direction, thereby reducing the influence of the screw on communication between the medium and the antenna.

[0008] In this aspect, a spacer is disposed between the antenna board and the head of the screw in the arrangement direction, and the case supports the antenna board in the arrangement direction. and a protrusion in which the screw hole is formed and protruding from the first surface portion to the second side, the antenna board has a hole into which the protrusion is inserted, the spacer is cylindrical into which the protrusion is inserted, and the antenna board is pressed against the support portion by the fastening force of the screw when the screw is fastened into the screw hole. In this way, even if the screw is positioned on the second side by the antenna board, the screw can fix the antenna board to the case by passing through the spacer.

[0009] In this aspect, it is preferable that a control board is disposed at the end of the second side of the spacer and controls the antenna board, and the screw is fastened to the screw hole via the control board, thereby making it possible to fix the antenna board and the control board to the case with a single screw.

[0010] In this aspect, the case preferably includes a first case having the first surface portion, and a second case assembled to the first case from the second side and having a second surface portion provided on the second side, and the screw is fastened to the screw hole from the second side of the second surface portion through the second surface portion. This allows the antenna board, the control board, and the second case to be fixed to the first case by a single screw.

[0011] In this aspect, the antenna is preferably provided on the first surface of the antenna substrate, thereby improving the communication sensitivity between the medium and the antenna. Effect of the Invention

[0012] According to this aspect, since no metal screws for fixing the antenna board are positioned between the medium and the antenna, the influence of the screws on communication between the medium and the antenna can be reduced. [Brief description of the drawings]

The information processing device 1 reads and writes data from and to the medium 2 by touching the first surface 33 with the medium 2 or bringing the medium 2 close to the first surface 33.

[0017] In the following description, the three mutually orthogonal directions are referred to as the X direction, the Y direction, and the Z direction. The X direction is the arrangement direction in which the first surface portion 33 and the antenna substrate 4 are arranged. In the X direction, the side where the first surface portion 33 is located is referred to as the X1 side (first side), and the side where the antenna substrate 4 is located is referred to as the X2 side (second side). In the Y direction, one side is referred to as the Y1 side, and the other side is referred to as the Y2 side. One side in the Z direction is referred to as the Z1 side, and the other side is referred to as the Z2 side.

[0018] (case) The case 3 is made of resin. When viewed from the X direction, the case 3 has a rectangular shape. The case 3 includes a first case 31 having a first surface portion 33, and a second case 32 assembled to the first case 31 from the X2 side. As shown in Figs. 3 and 4, the first case 31 includes a support portion 34 that supports the antenna board 4 in the X direction, and a protruding portion 35 that protrudes from the first surface portion 33 to the X2 side.

[0019] The support parts 34 are provided at the four corners of the X2 side surface of the first surface part 33. The four support parts 34 abut against the antenna board 4 to support the antenna board 4. The protrusion part 35 is cylindrical. A screw hole 351 is formed in the center of the protrusion part 35.

[0020] 1 and 4, first case 31 includes a first side surface portion 311 protruding from the outer periphery of first face portion 33 toward the X2 side, a flat surface portion 312 spreading out from an end of first side surface portion 311, and a second side surface portion 313 protruding from the outer periphery of flat surface portion 312 toward the X2 side. As shown in FIGS. 3 and 4, the end of second side surface portion 313 on the X2 side abuts against second case 32 via a frame-shaped seal member 8. Seal member 8 is an elastic member made of rubber, silicone, or the like.

[0021] 3 and 4, the second case 32 has a second surface 36 provided on the X2 side. The second surface 36 has a recess 37 that accommodates the head 51 of the screw 5. The recess 37 is recessed towards the X1 side. A bottom surface 370 of the recess 37 is provided with a hole 39 into which the screw 5 is inserted. The second case 32 is fixed to the first case 31 by the screw 5.

[0022] (Antenna board) As shown in FIG. 5, the antenna substrate 4 is flat. The antenna substrate 4 includes a loop-shaped antenna 41 and eight LED elements 42 on the surface 43 on the X1 side. The antenna 41 is a coil antenna and communicates with the medium 2. The antenna 41 is disposed near the outer periphery of the surface 43 on the X1 side. The LED elements 42 are disposed inside the antenna 41. The number of the LED elements 42 is not limited to eight. The LED elements 42 emit light by the output power from the control substrate 7. More specifically, when the user touches or brings the medium 2 close to the first surface 33, if the antenna 41 and the medium 2 are at an appropriate distance to enable communication, the LED elements 42 emit light to inform the user that the information processing device 1 is reading or writing data from the medium 2. On the other hand, if the antenna 41 and the medium 2 are not at an appropriate distance to enable communication, the LED elements 42 do not emit light, thereby informing the user that the information processing device 1 is not processing the medium 2.

[0023] 3 to 5, the antenna substrate 4 has a circular hole 45 into which the protrusion 35 is inserted. The hole 45 is disposed inside the antenna 41. As shown in FIG. 4, the antenna substrate 4 abuts against the support portion 34 with the protrusion 35 inserted into the hole 45.

[0024] (Spacer) 3 and 4, the spacer 6 is made of resin. The spacer 6 is cylindrical into which the protrusion 35 is inserted. The spacer 6 is located between the antenna board 4 and the control board 7. With the spacer 6 inserted into the protrusion 35, an end 61 on the X1 side abuts against the antenna board 4, and an end 62 on the X2 side abuts against the control board 7.

[0025] (Control board) As shown in Fig. 3, the control board 7 is flat. As shown in Fig. 4, the control board 7 is disposed at the end 62 of the spacer 6. At this time, the control board 7 does not abut against the end surface 352 of the protrusion 35. In other words, the end surface 352 of the protrusion 35 is located on the X1 side relative to the end 62 of the spacer 6.

[0026] The control board 7 is electrically connected to the antenna board 4 and includes a circuit for controlling the antenna board 4. The control board 7 communicates with the medium 2 by electromagnetic induction between the antenna 41 and the medium 2. As shown in Figs. 2 and 3, the antenna board 4 includes a connector terminal 71 provided on a surface 72 on the X2 side, and a hole 73. The connector terminal 71 protrudes outward from a hole 38 provided on the second surface 36. A connector of a higher-level device connected to the information processing device 1 is connected to the connector terminal 71.

[0027] (screw) The screw 5 is made of metal. As shown in Fig. 4, the screw 5 is inserted into the hole 39 from the X2 side of the second surface portion 36 and fastened into the screw hole 351. At this time, the screw 5 fixes the antenna board 4 to the first case 31 via the bottom surface portion 370 of the second case 32, the control board 7, and the spacer 6. In addition, the spacer 6 presses the antenna board 4 against the support portion 34 of the first case 31 by the fastening force of the screw 5 when the screw 5 is fastened into the screw hole 351.

[0028] 3 and 4, the protruding portion 35 has a protruding portion 353 protruding from an end face 352. The outer diameter dimension of the protruding portion 353 is slightly smaller than the hole 73 of the control board 7. The protruding portion 353 is inserted into the hole 73 to such an extent that it does not come into contact with the bottom surface portion 370 of the second case 32. As a result, when the antenna board 4, the spacer 6, the control board 7, and the second case 32 are assembled to the first case 31, the protruding portion 353 functions as a positioning portion for the control board 7.

[0029] 4, when viewed from a direction perpendicular to the X direction, the screw 5 is located on the X2 side of the antenna substrate 4 and does not overlap with the antenna substrate 4. More specifically, when viewed from a direction perpendicular to the X direction, the tip 53 of the screw 5 is located on the X2 side of the antenna substrate 4 and does not overlap with the antenna substrate 4.

[0030] (Action and effect) According to this embodiment, the screw 5 is located on the X2 side of the antenna substrate 4, and does not overlap with the antenna substrate 4 when viewed from a direction perpendicular to the X direction. As a result, the tip 53 of the screw 5 is not located on the X1 side of the antenna substrate 4, so that the influence of the screw 5 on the communication between the medium 2 and the antenna 41 can be reduced.

[0031] The information processing device 1 has a spacer disposed between the antenna board 4 and the head 51 of the screw 5 in the X direction. The case 3 has a support portion 34 that supports the antenna board 4 in the X direction, and a protruding portion 35 in which a screw hole 351 is formed and that protrudes from the first surface portion 33 to the X2 side. The antenna board 4 has a hole portion 45 into which the protruding portion 35 is inserted. The spacer 6 is cylindrical in shape and into which the protruding portion 35 is inserted. The spacer 6 presses the antenna board 4 against the support portion 34 of the case 3 by the fastening force of the screw 5 when the screw 5 is fastened into the screw hole 351. As a result, even if the screw is positioned on the X2 side by the antenna board 4, the screw 5 The antenna board 4 can be fixed to the case 3 via the spacer 6 .

[0032] The information processing device 1 has a control board 7 that is disposed at the end 62 on the X2 side of the spacer 6 and controls the antenna board 4. The screw 5 is fastened to the screw hole 351 via the control board 7. This allows the antenna board 4 and the control board 7 to be fixed to the case 3 by the single screw 5.

[0033] The case 3 includes a first case 31 having a first surface portion 33, and a second case 32 having a second surface portion 36 attached to the first case 31 from the X2 side and provided on the X2 side. The screw 5 is fastened into the screw hole 351 from the X2 side of the second surface portion 36 through the second surface portion 36. This allows the antenna board 4, the control board 7, and the second case 32 to be fixed to the first case 31 by a single screw.

[0034] The antenna 41 is provided on the surface 43 on the X1 side of the antenna substrate 4. This makes it possible to improve the communication sensitivity between the medium 2 and the antenna 41.
