The receiving portion 47 is formed with a portion on the front side open.

[0021] As shown in FIGS. 3 and 4, at the rear part of the case body 42, on both sides located in the left-right direction, box-shaped accommodating portions 44 for accommodating the engaging pieces 46 are provided. Each of the accommodating portions 44 has an open upper surface, and the engaging pieces 46 are exposed from the upper surface. The engaging piece 46 is formed in a claw shape in which the upper end bends toward the outside of the case body 42 along the left-right direction. The engaging piece 46 is held in the accommodating portion 44 so as to be movable in the left-right direction and is urged by a spring member or the like. As shown in FIG. 3, an operator 48 that can be slid by a user's finger is provided at the lower end of the engaging piece 46. The operator 48 is exposed on the rear surface side of the accommodating portion 44.

[0022] As shown in FIG. 3, a plurality of legs 50 are provided on the bottom surface of the bottom plate 42D. The legs 50 are arranged at each corner of the bottom plate 42D which is rectangular in plan view. The bottom plate 42D is spaced apart from the installation surface by these legs 50. As shown in FIG. 4, a notch 52 formed by being notched toward the front end is provided at the rear end of the bottom plate 42D. The notch 52 is arranged between a pair of accommodating portions 44 in plan view.

[0023] As shown in FIGS. 2 and 3, the lid 60 includes a front plate 60A with an open lower surface and forming the front surface, a pair of side plates 60B and 60C forming the left and right side surfaces, an upper plate 60D forming the upper surface, and a rear plate 60E forming the rear surface. A transmissive portion 62 through which the light of the LED 19 passes is provided on the front plate 60A. The transmissive portion 62 is formed by a transparent member or the like at a position overlapping the plurality of exposed holes 45. In the relay device 1, the LED module 11, the exposed holes 45, and the transmissive portion 62 function as a display portion. At the front end of each of the pair of side plates 60B and 60C, a protruding portion 63 protruding toward the case body 42 is provided. The protruding portion 63 is provided at a position corresponding to the receiving portion 47 and fits into the receiving portion 47 when the lid 60 covers the case body 42.

[0024] A plurality of cushioning members 64 are provided on the upper plate 60D on the surface facing the case body 42. The cushioning members 64 are members having flexibility such as a rubber material, for example. The cushioning members 64 abut against various components accommodated in the case body 42 when the box-shaped case body 42 is covered with the box-shaped lid 60. A pair of engaging pieces 66 are provided on the upper plate 60D on the surface facing the case body 42. Each of the engaging pieces 66 is provided at a position where it can engage with each of the engaging pieces 46, and engages with each of the engaging pieces 46 when the lid 60 covers the case body 42.

[0025] As shown in FIG. 3, the rear plate 60E extends in the vertical direction to a position where the lower end portion approaches the bottom plate 42D. For this reason, in the case where the box-shaped case body 42 of the case 40 is covered with the box-shaped lid body 60, a drawer hole 41 having a hole shape surrounded by the notch portion 52 and the lower end portion of the bottom plate 42D is formed.

[0026] The upper plate 60D is formed to be a flat surface. As a result, other devices and the like provided in the POS system 100 can be placed on the upper surface of the relay device 1.

[0027] As shown in FIG. 4, in the central portion of the case body 42, the power adapter 28 and the main board housing 70 that houses the main board 3 are arranged side by side along the horizontal direction. That is, the power adapter 28 and the main board housing 70 are arranged so as to be aligned in a predetermined direction in plan view. In the present embodiment, the power adapter 28 and the main board housing 70 are arranged side by side adjacent to each other along the left-right direction. With this arrangement, the main board 3 housed in the power adapter 28 and the main board housing 70 is arranged side by side inside the case 40.

[0028] As a result, in the relay device 1, an increase in the height dimension can be suppressed. Furthermore, in the relay device 1, the case 40 can accommodate both the main board housing 70 to which various connectors can be connected and the power adapter 28 that supplies power to the relay device 1. For this reason, in the relay device 1 and the POS system 100, even when a plurality of so-called POS terminals and POS peripheral devices are connected, a more organized system can be formed.

[0029] In the case body 42, other devices, parts, members, etc. may be arranged between the power adapter 28 and the main board housing 70.

[0030] The power adapter 28 of this embodiment is a general-purpose product. The power adapter 28 is provided with a power connector 22 into which a power cable 29 can be inserted and removed.

[0031] The power adapter 28 is housed in an adapter housing portion 54 provided inside the case main body 42. The adapter housing portion 54 is a space surrounded by a plate-shaped positioning portion 56 provided so as to stand up from the upper surface of the bottom plate 42D. When the power adapter 28 is housed in the adapter housing portion 54, it is surrounded by the positioning portion 56. As a result, the horizontal movement of the power adapter 28 is restricted. At a predetermined position at the upper end of the positioning portion 56, a claw-shaped engaging portion 57 is provided. As a result, the vertical movement of the power adapter 28 is restricted.

[0032] The power adapter 28 of this embodiment is a general-purpose product. The power adapter 28 is provided with a power connector 22 into which a power cable 29 can be inserted and removed. The power adapter 28 is housed in the adapter housing portion 54 so that the power connector 22 is located on the rear end side of the case main body 42.

[0033] A pressing spring 58 is provided inside the case main body 42. The pressing spring 58 is a member formed by bending a linear metal material into a U shape. The pressing spring 58 is formed so that both ends in the longitudinal direction can be inserted into a pair of insertion holes 59 provided at the upper ends of predetermined positions of the positioning portion 56. The pressing spring 58 is arranged to press the upper surface of the power adapter 28 by being inserted into the insertion holes 59. As a result, the power adapter 28 is fixed to the case main body 42.

[0034] As described above, the pressing spring 58 is formed to be easily detachable. Therefore, in the relay device 1, the power adapter 28, which is a variety of general-purpose products, can be easily fixed and detached. The pressing spring 58 corresponds to the "fixing portion" of the present disclosure.

[0035] A cord holding portion 76 is provided inside the case body 42, near a corner formed by the front panel 42A and the side panel 42C. The cord holding portion 76 includes a pair of columnar winding portions 78 extending rearward from the front panel 42A. The pair of winding portions 78 are arranged with a predetermined gap between them in the left-right direction. The power adapter cable 27 is wound around the pair of winding portions 78. In this case, the power adapter cable 27 may be wound around the pair of winding portions 78 in a figure-eight pattern.

[0036] This allows the relay device 1 to reduce the space required to accommodate the power adapter cable 27 inside the case 40, and also allows it to be accommodated in a state that reduces noise relative to other electrical components.

[0037] A connection board housing 68 is provided inside the case body 42, near a corner formed by the front plate 42A and the side plate 42B. The switch module 9, the LED module 11, and the wireless module 13 are housed inside the connection board housing 68 so that they are stacked in the vertical direction. This allows the relay device 1 to reduce the space required to accommodate the switch module 9, the LED module 11, and the wireless module 13 inside the case 40, and also reduces the dimensions of the relay device 1 in a plan view. Therefore, the relay device 1 can have a smaller case 40.

[0038] In addition, in the case main body 42, the switch module 9, LED module 11, and wireless module 13 are arranged so as to overlap each other in the vertical direction, and other equipment, parts, components, etc. may be arranged between each of these modules arranged opposite each other.

[0039] FIG. 5 is a perspective view of various connectors provided in the relay device 1 as viewed from the rear. As described above, the main board 3 is housed in the main board housing 70. In the main board housing 70, as shown in FIG. 5, the LAN connector 30, the modular connector 31, a plurality of serial connectors 32, a plurality of USB Type-C connectors 34, and a plurality of USB Type-A connectors 36 are arranged so as to open toward the rear of the case 40. In the present embodiment, the plurality of serial connectors 32 are arranged above the other connectors.

[0040] At the rear end of the bottom plate 42D, two cable holders 80 are attached. The cable holder 80 is formed so as to be able to hold the cabled cable 72 inserted into each of the USB Type-C connectors 34 from below. The cable holder 80 prevents the cabled cable 72 from coming off. The cabled cable 72 is shown in FIG. 6 described later. The cable holder 80 includes a fixed rail portion 82 and a retaining member 90 that is movably provided with respect to the fixed rail portion 82.

[0041] As shown in FIG. 5, the fixed rail portion 82 has a pair of rib shapes standing up from the bottom plate 42D. The fixed rail portion 82 extends along the front-rear direction of the case 40. By providing the rib shape, a groove 81 is formed between the rib shapes in the fixed rail portion 82. In the bottom plate 42D, bosses 86 protruding upward are provided at positions adjacent to the fixed rail portion 82. The bosses 86 are provided with screw holes that are recessed downward from the upper ends.

[0042] The retaining member 90 is a slider-shaped member formed of a resin member separate from the case 40. The retaining member 90 is a long member extending along the front-rear direction of the case 40 in a plan view. 4, the lower surface of the retaining member 90 is provided with a protrusion 92 that protrudes from the lower surface and fits into the groove 81. As a result, the retaining member 90 is guided by the fixed rail portion 82, and is therefore movable in the insertion / removal direction of the connector-equipped cable 72. Additionally, the relay device 1 can prevent the retaining member 90 from shifting in the left-right direction. Furthermore, the anti-slip member 90 is guided by the fixed rail portion 82, and is therefore movable within a range that allows it to fit inside the case 40. This prevents the relay device 1 from becoming larger.

[0043] The retaining member 90 has an elongated hole 91 that penetrates in the up-down direction. The elongated hole 91 extends along the front-to-rear direction of the case 40 in a plan view. A setscrew 84 is inserted into the elongated hole 91. The setscrew 84 is a so-called thumb screw. The setscrew 84 is threaded into a threaded hole in the boss 86. By operating the setscrew 84 without using any tools, the user can slide the retaining member 90 and fix it in a desired position.

[0044] A pair of upwardly rising abutting portions 94 are provided at the front end of the slippage prevention member 90. The abutting portions 94 are plate-like portions arranged side by side in the left-right direction with a gap therebetween that allows the cable portion 73 of the connector-equipped cable 72 to be inserted therethrough.

[0045] FIG. 6 is a perspective view of various connectors provided in the relay device 1 when the connectorized cable 72 is connected, as viewed from the rear. When the connector-equipped cable 72 is connected to the USB Type-C connector 34, first, the cable portion 73 is inserted between the pair of abutment portions 94. Next, the tip end of the connector portion 74 is inserted into the USB Type-C connector 34.

[0046] Thereafter, the user slides the disconnection prevention member 90 to a position where the pair of contact portions 94 contact the rear end of the connector portion 74 . When the anti-disengagement member 90 moves to a position where the pair of contact portions 94 contact the rear end of the connector portion 74, the user tightens the set screw 84, whereby the anti-disengagement member 90 is fixed at that position. In this way, the connector portion 74 can be prevented from detaching from the USB Type-C connector 34 by being sandwiched between the pair of contact portions 94 and the rear surface of the main board housing 70.

[0047] The anti-disengagement member 90 is formed to be slidable in the front-rear direction, so that the fixed position can be changed according to the size, shape, etc. of the connector portion 74 of the cable with connector 72. Accordingly, in the relay device 1, regardless of the size, shape, etc. of the connector portion 74, the cable with connector 72 can be prevented from detaching from the USB Type-C connector 34.

[0048] As described above, a plurality of anti-disengagement members 90 are provided corresponding to the number of USB Type-C connectors 34. The plurality of anti-disengagement members 90 have the same form, and commonization of parts is achieved. In the present embodiment, the plurality of anti-disengagement members 90 are each independently movably provided on the fixed rail portion 82. However, it is not limited thereto, and the plurality of anti-disengagement members 90 may be integrally formed and provided on the fixed rail portion 82 so as to be integrally movable.

[0049] Next, the operation of the relay device 1 will be described. As described above, when connecting various cables to the relay device 1, the user first slides the operator 48. As a result, the engaging piece 46 disengages from the engaging piece 44, and the rear end side of the lid body 60 moves upward by the elastic force of the buffer material 64. After that, the user disengages the protruding portion 63 from the receiving portion 47 by passing through the opened portion of the receiving portion 47, and removes the lid body 60 from the case body 42. Thereby, the user can access various connectors arranged on the rear surface of the main board housing 70, the power connector 22, and the power adapter 28.

[0050] After performing a desired operation on the relay device 1, the user attaches the lid 60 to the case body 42. In this case, the cables and the power cable 29 connected to various connectors arranged on the rear surface of the main board housing 70 are all drawn out from the drawing hole 41. Since the drawing hole 41 opens facing the installation surface of the relay device 1, the cables and the power cable 29 connected to various connectors all extend downward. In this way, in the relay device 1, since various cables and the power cable 29 are drawn out by being concentrated in a single drawing hole 41, the cables can be easily sorted and routed.

[0051] Furthermore, in the relay device 1, since the rear surface is covered by the rear plate 60E, various cables and the power cable 29 are shielded in a rear view, and the design can be improved.

[0052] In the relay device 1, various cables and the power cable 29 drawn out from the drawing hole 41 may be routed between the bottom plate 42D and the installation surface. In this case, in the relay device 1, by arranging these cables between each of the legs 50, it is possible to concentrate and arrange the cables within the installation range of the relay device 1.

[0053] Next, a modified example of the present embodiment will be described. FIG. 7 is a perspective view of the relay device 200 in a modified example of the present disclosure as viewed from the rear. In FIG. 7, for convenience of explanation, the case 240 is shown by a two-dot chain line. In FIG. 7, the same reference numerals are given to the portions common to FIGS. 2 to 6, and the description thereof is omitted. As shown in FIG. 7, in the relay device 200 in the modified example of the present disclosure, in a plan view, the main board housing 70 and the power adapter 28 are arranged so as to overlap.

[0054] The relay device 200 includes a case 240. Similar to the case 40, the case 240 is formed by covering a box-shaped case body 242 with a box-shaped lid 260. Similar to the case 40, the case 240 is provided with a drawer hole 241 that opens downward.

[0055] Inside the case 240, the power adapter 28, together with the power adapter cable 27, is disposed below the main board housing 70. The power adapter 28 and the power adapter cable 27 are arranged side by side along the left-right direction. Thereby, in the relay device 200, an increase in the dimension in the horizontal direction can be suppressed.

[0056] Note that the main board housing 70 and the power adapter 28 may be arranged in the case 240 such that at least a part thereof overlaps in a plan view. Also, other devices, components, members, etc. may be arranged between the main board housing 70 and the power adapter 28. With such an arrangement, the main board 3 housed in the power adapter 28 and the main board housing 70 are arranged so as to overlap vertically.

[0057] Note that the above-described embodiments are merely examples of one aspect of the present invention, and can be arbitrarily modified and applied within the scope of the gist of the present invention.

[0058] In the above-described embodiment, it is assumed that the power adapter 28 is housed in the relay device 1, but the present invention is not limited thereto, and various power supply devices such as a battery pack may be housed.

[0059] Each part shown in FIG. 1 is an example, and the specific mounting form is not particularly limited. That is, it is not necessarily the case that hardware corresponding to each part is mounted individually, and of course, a configuration may be adopted in which one processor executes a program to realize the functions of each part. Also, a part of the functions realized by software in the above-described embodiment may be implemented as hardware, or a part of the functions realized by hardware may be implemented by software.

[0060] In the above-described embodiments, horizontal and vertical directions, various shapes, etc. include the so-called equivalent ranges that exhibit the same operational effects as those directions, numerical values, and shapes, unless otherwise specified.
