The receiving portions 47 are formed with an open portion located on the front side.

[0020] 3 and 4, box-shaped storage sections 44 for storing engagement pieces 46 are provided on both left and right sides of the rear of the case body 42. Each storage section 44 has an open top, from which the engagement pieces 46 are exposed. The engagement piece 46 is formed in a claw shape with its upper end bent toward the outside of the case body 42 in the left-right direction. The engagement piece 46 is held in the storage section 44 so as to be movable in the left-right direction, and is biased by a spring member or the like. As shown in FIG. 3, an operator 48 is provided at the lower end of the engagement piece 46 so that the user can slide it with their finger. The operator 48 is exposed on the rear side of the storage section 44.

[0021] 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 rectangular bottom plate 42D in a plan view. The legs 50 allow the bottom plate 42D to be spaced apart from the installation surface. 4, the rear end of the bottom plate 42D is provided with a notch 52 that is formed by cutting out toward the front end. The notch 52 is disposed between the pair of storage portions 44 in a plan view.

[0022] As shown in Figures 2 and 3, the cover body 60 has an open bottom and comprises a front plate 60A that forms the front surface, a pair of side plates 60B and 60C that form the left and right sides, an upper plate 60D that forms the top surface, and a rear plate 60E that forms the rear surface. The front panel 60A is provided with a transmission portion 62 that transmits light from the LEDs 19. The transmission portion 62 is formed of a transparent member or the like at a position that overlaps the multiple exposure holes 45. In the relay device 1, the LED module 11, the exposure holes 45, and the transmission portion 62 function as a display portion. A protrusion 63 that protrudes toward the case body 42 is provided at the front end of each of the pair of side plates 60B, 60C. The protrusion 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.

[0023] A plurality of cushioning materials 64 are provided on the surface of the upper plate 60D facing the case body 42. The cushioning materials 64 are flexible members such as rubber. When the box-shaped case body 42 is covered with the box-shaped lid 60, the cushioning materials 64 come into contact with the various components housed in the case body 42. The upper plate 60D is provided with a pair of engagement pieces 66 on the surface facing the case body 42. Each of the engagement pieces 66 is provided at a position where it can engage with each of the engagement pieces 46, and engages with each of the engagement pieces 46 when the lid body 60 covers the case body 42.

[0024] 3, rear plate 60E extends in the up-down direction to a position where its lower end approaches bottom plate 42D. Therefore, when box-shaped case body 42 is covered with box-shaped lid 60, case 40 has extraction hole 41, which is a hole surrounded by notch 52 and the lower end of bottom plate 42D.

[0025] The upper plate 60D is formed to have a flat surface, which allows other devices, etc., included in the POS system 100 to be placed on the upper surface of the relay device 1.

[0026] 4, power adapter 28 and main board housing 70, which houses main board 3, are arranged side by side in the horizontal direction in the center of case body 42. That is, power adapter 28 and main board housing 70 are arranged so as to line up in a predetermined direction in a plan view. In this embodiment, the power adapter 28 and the main board housing 70 are arranged side by side in the left-right direction. With this arrangement, the power adapter 28 and the main board 3 housed in the main board housing 70 are arranged side by side inside the case 40.

[0027] This makes it possible to suppress an increase in the height of the relay device 1. Furthermore, in the relay device 1, the case 40 can accommodate both a main board housing 70 to which various connectors can be connected, and a power adapter 28 that supplies power to the relay device 1. Therefore, in the relay device 1 and the POS system 100, a more organized system can be formed even when multiple so-called POS terminals or POS peripheral devices are connected.

[0028] In addition, in the case body 42, other devices, parts, members, etc. may be arranged between the power adapter 28 and the main board housing 70.

[0029] The power adapter 28 of this embodiment is a general-purpose product and is provided with a power connector 22 into which a power cable 29 can be inserted and removed.

[0030] The power adapter 28 is housed in an adapter housing 54 provided inside the case body 42. The adapter housing 54 is a space surrounded by a plate-shaped positioning portion 56 that stands up from the upper surface of the bottom plate 42D. When the power adapter 28 is housed in the adapter housing 54, it is surrounded on all sides by the positioning portion 56. This restricts horizontal movement of the power adapter 28. At a predetermined position at the upper end of the positioning portion 56, a claw-shaped engaging portion 57 is provided. Thereby, the vertical movement of the power adapter 28 is restricted.

[0031] The power adapter 28 of the present embodiment is a general-purpose product. The power adapter 28 is provided with a power connector 22 into which the 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 body 42.

[0032] A pressing spring 58 is provided inside the case 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 so as to press the upper surface of the power adapter 28 by being inserted into the insertion hole 59. Thereby, the power adapter 28 is fixed to the case body 42.

[0033] 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.

[0034] Inside the case body 42, a cord holding portion 76 is provided at a position close to the corner formed by the front plate 42A and the side plate 42C. The cord holding portion 76 includes a pair of columnar winding portions 78 extending rearward from the front plate 42A. The pair of winding portions 78 are arranged at a predetermined interval 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 so as to form an 8 shape.

[0035] Thereby, in the relay device 1, the space required for accommodating the power adapter cable 27 can be made smaller inside the case 40, and it is possible to accommodate it in a state where noise can be reduced with respect to other electrical components.

[0036] Inside the case body 42, a connection board housing 68 is provided at a position close to the corner formed by the front plate 42A and the side plate 42B. Inside the connection board housing 68, the switch module 9, the LED module 11, and the wireless module 13 are housed so as to overlap in the vertical direction. As a result, in the relay device 1, the space required for housing the switch module 9, the LED module 11, and the wireless module 13 can be made smaller inside the case 40, and the dimensions of the relay device 1 in plan view can be made smaller. For this reason, in the relay device 1, the case 40 can be miniaturized.

[0037] In the case body 42, between each of the switch module 9, the LED module 11, and the wireless module 13 arranged so as to overlap in the vertical direction, other devices, parts, members, etc. may be arranged.

[0038] FIG. 5 is a perspective view of various connectors provided in the relay device 1 viewed from the back. 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.

[0039] Two cord holders 80 are attached to the rear end of the bottom plate 42D. The cord holder 80 is formed so as to be able to hold the cabled cable 72 with a connector that is inserted into and removed from each of the USB Type-C connectors 34 from below. The cord holder 80 prevents the cabled cable 72 with a connector from coming off. The cabled cable 72 with a connector is shown in FIG. 6 described later. The cord holder 80 includes a fixed rail portion 82 and a slip-out prevention member 90 that is movably provided relative to the fixed rail portion 82. The cord holder 80 corresponds to the "holding portion" in this disclosure, the fixed rail portion 82 corresponds to the "fixed portion" in this disclosure, and the anti-slip member 90 corresponds to the "anti-slip portion" in this disclosure.

[0040] 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 shapes, grooves 81 are formed in the fixed rail portion 82 between the rib shapes. An upwardly protruding boss 86 is provided on the bottom plate 42D at a position adjacent to the fixed rail portion 82. The boss 86 is provided with a screw hole recessed downward from the upper end.

[0041] The slip-out prevention member 90 is a slider-shaped member formed of a resin member separate from the case 40. The slip-out prevention member 90 is an elongated member that extends 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.

[0042] 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. The set screw 84 corresponds to the "fastening member" of the present disclosure.

[0043] 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.

[0044] 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.

[0045] 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-slip member 90 has moved to a position where the pair of abutment portions 94 abut against the rear end of the connector portion 74, the user tightens the setscrew 84, thereby fixing the anti-slip member 90 in that position. In this way, the connector portion 74 is sandwiched between the pair of abutment portions 94 and the rear surface of the main board housing 70, thereby preventing the connector portion 74 from coming off the USB Type-C connector 34.

[0046] The anti-disconnection 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 72 with a connector. Accordingly, in the relay device 1, regardless of the size, shape, etc. of the connector portion 74, it is possible to prevent the cable 72 with a connector from detaching from the USB Type-C connector 34.

[0047] As described above, a plurality of anti-disconnection members 90 are provided corresponding to the number of USB Type-C connectors 34. The plurality of anti-disconnection members 90 have the same form, and common use of parts is achieved. In the present embodiment, the plurality of anti-disconnection members 90 are each independently movably provided on the fixed rail portion 82. However, the present invention is not limited to this, and the plurality of anti-disconnection members 90 may be integrally formed and provided on the fixed rail portion 82 so as to be integrally movable.

[0048] Next, an operation on 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 detaches 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. As a result, 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.

[0049] After performing a desired operation on the relay device 1, the user attaches the lid body 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 in a concentrated manner through a single lead-out hole 41, the cables can be easily organized and routed.

[0050] 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 when viewed from the back, and the design can be improved.

[0051] In the relay device 1, various cables and the power cable 29 drawn out from the lead-out 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.

[0052] Next, a modification of this embodiment will be described. FIG. 7 is a perspective view of the relay device 200 in a modification of the present disclosure as viewed from the back. 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 modification of the present disclosure, in a plan view, the main board housing 70 and the power adapter 28 are arranged so as to overlap. The relay devices 1 and 200 correspond to the "electronic device" of the present disclosure.

[0053] The relay device 200 includes a case 240. The case 240 is formed in the same manner as the case 40, that is, a box-shaped case body 242 is covered with a box-shaped lid body 260. The case 240 is provided with a lead-out hole 241 that opens downward, similar to the case 40.

[0054] Inside the case 240, the power adapter 28 is arranged below the main board housing 70 together with the power adapter cable 27. The power adapter 28 and the power adapter cable 27 are arranged side by side along the left-right direction. This makes it possible to suppress an increase in the horizontal dimension of the relay device 200.

[0055] Note that main board housing 70 and power adapter 28 may be arranged in case 240 so that they at least partially overlap in a plan view. In addition, other devices, parts, members, etc. may be arranged between main board housing 70 and power adapter 28. With this arrangement, the power adapter 28 and the main board 3 housed in the main board housing 70 are arranged so as to be stacked one on top of the other.

[0056] The above-described embodiment is merely an example of one aspect of the present invention, and any modifications and applications are possible within the scope of the gist of the present invention.

[0057] In the above-described embodiment, the relay device 1 is provided with the power adapter 28, but the present invention is not limited to this and various types of power supply devices such as a battery pack may be provided with the relay device 1.

[0058] The units shown in Figure 1 are merely examples, and the specific implementation form is not particularly limited. In other words, it is not necessary to implement hardware corresponding to each unit individually, and it is of course possible to configure the units so that the functions are realized by a single processor executing a program. Furthermore, some of the functions realized by software in the above-described embodiments may be implemented by hardware, or some of the functions realized by hardware may be implemented by software.

[0059] Unless otherwise specified, the horizontal, vertical, and other directions and various shapes in the above-described embodiments include a so-called equivalent range that provides the same action and effect as those directions, values, and shapes.
