[0013] Preferred embodiments of the present invention will be described in detail below with reference to the attached drawings. The dimensions, materials, and other specific numerical values ​​shown in these embodiments are merely examples to facilitate understanding of the invention and do not limit the present invention unless otherwise specified. In this specification and drawings, elements having substantially the same function and configuration are denoted by the same reference numerals to avoid redundant explanations, and elements not directly related to the present invention are omitted from the illustrations.

[0014] [1. Overview of the Tablet Device Assembly] An overview of a tablet terminal assembly 100 according to an embodiment of the present invention will be described with reference to Figures 1 and 2.

[0015] Figures 1 and 2 are perspective views showing a tablet terminal assembly 100 according to this embodiment. As shown in Figures 1 and 2, the tablet terminal assembly 100 comprises a tablet terminal 10 and a stay 20 (see Figure 2). The tablet terminal assembly 100 is installed in a taxi 1 and used for payment of taxi fares, etc.

[0016] Hereinafter, an example in which the vehicle in which the tablet terminal assembly 100 is installed is a taxi 1 will be described. However, the vehicle in which the tablet terminal assembly 100 is installed may be a vehicle other than taxi 1. For example, the vehicle in which the tablet terminal assembly 100 is installed may be a ride-sharing vehicle such as an NRS vehicle, a bus, or other commercial vehicles that transport passengers. Note that NRS is an abbreviation for "Nippon-style Ride Share" or "Nihon-gata Ride Share". Ride share refers to a service in which ordinary drivers use private cars, etc. to有偿 transport users. A ride-sharing vehicle is an automobile such as a private car or commercial vehicle used in ride sharing.

[0017] In each of the drawings referred to hereinafter, the vehicle front direction, vehicle rear direction, vehicle upper direction, vehicle lower direction, vehicle left direction, and vehicle right direction are shown as front, rear, upper, lower, left, and right, respectively. Hereinafter, the vehicle front-rear direction, vehicle up-down direction, and vehicle left-right direction will also be simply referred to as the front-rear direction, up-down direction, and left-right direction.

[0018] The tablet terminal 10 is an information processing terminal including a CPU (Central Processing Unit), ROM (Read Only Memory), and RAM (Random Access Memory), etc. The tablet terminal 10 receives operations from passengers and is capable of communicating with various in-vehicle devices (for example, terminals used by crew members, etc.) installed in the passenger compartment of taxi 1. A payment device is incorporated in the tablet terminal 10, and the tablet terminal 10 can perform processing related to the payment of taxi fares.

[0019] The tablet terminal 10 has a rectangular flat plate shape that is long in the left-right direction. That is, the length of the tablet terminal 10 in the left-right direction is longer than the length of the tablet terminal 10 in the up-down direction. The tablet terminal 10 is attached to the rear part of the seat 2 of the front seat (specifically, the driver's seat or the passenger seat). The tablet terminal 10 is installed in a posture facing backward (specifically, in a posture where the display screen 12 described later faces backward).

[0020] A passenger sitting in the rear seat of Taxi 1 can operate or view a tablet terminal 10 located in front of him / her. For example, the passenger can settle the taxi fare by operating the tablet terminal 10. The settlement of the taxi fare is performed using a payment card such as a magnetic card, a contact-type IC card, a non-contact-type IC card, etc. Also, for example, the passenger can view an image displayed on a display screen 12 described later.

[0021] As shown in FIGS. 1 and 2, the tablet terminal 10 has a housing 11 and a display screen 12.

[0022] The housing 11 is an exterior material of the tablet terminal 10 and is formed of, for example, plastic. The housing 11 is configured by combining a plurality of members. The housing 11 forms the outer shape of the tablet terminal 10. Inside the housing 11, various devices such as a control board and a battery (not shown) are accommodated. The housing 11 has a function of covering and protecting these devices.

[0023] The display screen 12 is a screen that projects an image displayed by a display device built into the tablet terminal 10. The above display device is, for example, a liquid crystal display (LCD), or an organic EL display (OLED), etc.

[0024] The display screen 12 is provided on the front side (i.e., the rear side) of the tablet terminal 10. The area of the display screen 12 occupies most of the area of the front (i.e., the rear surface) of the tablet terminal 10. The outer periphery of the rectangular display screen 12 is surrounded by a rectangular frame that is a portion on the front side of the housing 11. The size of the display screen 12 is, for example, 13.3 inches. However, the size of the display screen 12 may be larger than 13.3 inches or smaller than 13.3 inches.

[0025] The display screen 12 displays various images, including still images and videos. The images displayed by the display screen 12 include, for example, advertisements, news, weather forecasts, video content (e.g., movies, television programs, videos or still images from image distribution services, etc.), taxi service details, taxi fare information, payment information, map information showing the taxi's current location or destination, the current time, menu images, etc.

[0026] As described above, the tablet device 10 is mounted on the rear of the front seat 2, facing backward. Here, the tablet device 10 is attached to the seat 2 by a stay 20. In other words, the stay 20 is a component for attaching the tablet device 10 to the seat 2.

[0027] As shown in Figure 2, the seat 2 includes a seat back 2a, a headrest 2b, and a headrest shaft 2c. The seat back 2a corresponds to the backrest of the seat 2 and supports the occupant's back. The headrest 2b supports the occupant's head from behind. The headrest 2b is connected to the top of the seat back 2a via the headrest shaft 2c. For example, the headrest shaft 2c has a cylindrical shape and extends upward from two locations on the top of the seat back 2a, one on the left and one on the right. The stay 20 is attached to the tablet terminal 10 and also to the headrest shaft 2c. Therefore, the tablet terminal 10 is attached to the headrest shaft 2c via the stay 20.

[0028] Here, the stay 20 may deform and break due to the load acting on the tablet terminal 10. For example, when passengers get on or off the vehicle, they may grab the tablet terminal 10, and the passenger's weight may be applied to the tablet terminal 10. Also, for example, the tablet terminal 10 may move up and down due to vibrations caused by the movement of the taxi 1. Under such circumstances, deformation of the stay 20 may occur. Therefore, in this embodiment, deformation of the stay 20 is suppressed by making improvements to the structure of the stay 20. The improvements to the structure of the stay 20 will be described below.

[0029] [2. Details of the tablet device assembly] Referring to Figures 3 to 5, the details of the tablet terminal assembly 100 according to an embodiment of the present invention will be described.

[0030] Figure 3 is an exploded perspective view showing the stay 20 according to this embodiment. Figures 4 and 5 are perspective views showing the tablet terminal assembly 100 according to this embodiment.

[0031] In the following, we will describe the shape of the stay 20 using examples shown in Figures 3 to 5. However, the examples shown in Figures 3 to 5 are merely examples, and as will be described later, the shape of the stay 20 is not limited to these examples.

[0032] As shown in Figures 3 to 5, the stay 20 has a first stay 21, a second stay 22, and a third stay 23. Hereinafter, the components of the stay 20 will be described mainly with reference to Figure 3, and with reference to Figures 4 and 5 as appropriate.

[0033] The first stay 21 is attached to the back surface 11a (i.e., the front surface) of the housing 11 of the tablet terminal 10 (see Figures 4 and 5). As shown in Figure 3, the first stay 21 includes a mounting portion 21a and a first cylindrical portion 21b. The first stay 21 is formed from a metal material such as stainless steel. The first stay 21 can be easily and inexpensively manufactured, for example, by bending a single metal plate to form its outer shape. For example, the single metal plate includes a roughly rectangular portion that becomes the mounting portion 21a after bending, and a plurality of protruding portions that project outward from the end of the rectangular portion, and the first cylindrical portion 21b is formed by bending the plurality of protruding portions.

[0034] The mounting portion 21a is attached to the rear surface 11a of the housing 11 and is provided along the rear surface 11a of the housing 11. The rear surface 11a of the housing 11 is provided parallel to a plane perpendicular to the front-rear direction. Therefore, the mounting portion 21a is provided parallel to a plane perpendicular to the front-rear direction. In reality, the rear surface 11a of the housing 11 is partially curved or bent.

[0035] Specifically, as shown in Figure 3, the mounting portion 21a has a substantially flat shape extending on a plane perpendicular to the front-rear direction. The outer shape of the mounting portion 21a is substantially rectangular, with sides in the left-right direction and sides in the up-down direction. For example, the mounting portion 21a is fixed to the back surface 11a of the housing 11 by screw fastening or the like.

[0036] Furthermore, as shown in Figure 3, an opening 21a1 is formed in the mounting portion 21a. The opening 21a1 is formed in the lower half of the mounting portion 21a in the vertical direction and in the central part of the mounting portion 21a in the horizontal direction. The opening 21a1 has a substantially rectangular shape with sides in the horizontal direction and sides in the vertical direction. As shown in Figure 4, when the mounting portion 21a is attached to the back surface 11a of the housing 11, a part of the back surface 11a of the housing 11 (for example, the part where the ventilation holes are formed) is exposed through the opening 21a1. As a result, for example, air can be circulated between the inside and outside of the housing 11 through the opening 21a1, and the device inside the housing 11 can be air-cooled.

[0037] Furthermore, as shown in Figure 3, ribs 21a2 are formed at the left and right ends of the mounting portion 21a, respectively. The ribs 21a2 have a substantially flat shape that protrudes forward from the left and right ends of the mounting portion 21a. The ribs 21a2 intersect (specifically, are perpendicular to) the left-right direction. The ribs 21a2 extend vertically from the upper end to the lower end of the mounting portion 21a. The rigidity of the mounting portion 21a is increased by the formation of ribs 21a2 at the left and right ends of the mounting portion 21a, respectively.

[0038] The first cylindrical portion 21b extends from the mounting portion 21a in a direction intersecting the mounting portion 21a. As described above, the mounting portion 21a is provided along the back surface 11a of the housing 11. In other words, the first cylindrical portion 21b extends in a direction intersecting the back surface 11a of the housing 11.

[0039] Specifically, as shown in Figure 3, the first cylindrical portion 21b has a cylindrical shape that extends forward from the lower end of the mounting portion 21a. In other words, when viewed from the front in the front-to-back direction, the first cylindrical portion 21b is annular. Specifically, when viewed from the front in the front-to-back direction, the outer shape of the first cylindrical portion 21b is substantially rectangular, having sides in the left-to-right direction and sides in the up-to-down direction. The length of the first cylindrical portion 21b in the left-to-right direction is longer than the length of the first cylindrical portion 21b in the up-to-down direction. An opening 21b1 is formed at the front end of the first cylindrical portion 21b.

[0040] Furthermore, as shown in Figure 3, a recess 21b2 is formed in the first cylindrical portion 21b. The recess 21b2 is a recessed portion extending forward from the rear end of the first cylindrical portion 21b and is formed on the central side in the left-right direction. The recess 21b2 is not part of the material, but is a space. As will be described later, the cable 31 of the harness 30 connected to the housing 11 is inserted through the recess 21b2.

[0041] The second stay 22 is connected to the first stay 21 and attached to the headrest shaft 2c of the seat 2 (see Figures 4 and 5). As shown in Figure 3, the second stay 22 includes a second cylindrical portion 22a, a protruding portion 22b, and a bushing assembly 22c. Of the second stay 22, the second cylindrical portion 22a and the protruding portion 22b are formed from a metal material such as stainless steel. The second stay 22 can be easily and inexpensively manufactured, for example, by bending a single metal plate to form its outer shape.

[0042] The second cylindrical portion 22a is fitted into the first cylindrical portion 21b of the first stay 21. This connects the second stay 22 to the first stay 21. In the examples shown in Figures 3 to 5, the second cylindrical portion 22a is fitted into the outer surface of the first cylindrical portion 21b of the first stay 21. That is, the first cylindrical portion 21b is inserted into the interior of the second cylindrical portion 22a, and the outer surface of the first cylindrical portion 21b is covered by the second cylindrical portion 22a. Therefore, as shown in Figures 4 and 5, when the second stay 22 is connected to the first stay 21, the first cylindrical portion 21b of the first stay 21 is not visible from the outside. However, when the second stay 22 is connected to the first stay 21, a part of the first cylindrical portion 21b of the first stay 21 may be visible from the outside.

[0043] Specifically, as shown in Figure 3, the second cylindrical portion 22a is provided at the rear of the second stay 22 and has a cylindrical shape that extends to the rear. In other words, when viewed from the rear in the front-to-back direction, the second cylindrical portion 22a is annular. Specifically, when viewed from the rear in the front-to-back direction, the outer shape of the second cylindrical portion 22a is substantially rectangular, having sides in the left-to-right direction and sides in the up-to-down direction. The length of the second cylindrical portion 22a in the left-to-right direction is longer than the length of the second cylindrical portion 22a in the up-to-down direction. An opening 22a1 is formed at the rear end of the second cylindrical portion 22a.

[0044] Here, the length of the opening 22a1 of the second cylindrical portion 22a in the left-right direction is longer than the length of the first cylindrical portion 21b in the left-right direction. Also, the length of the opening 22a1 of the second cylindrical portion 22a in the up-down direction is longer than the length of the first cylindrical portion 21b in the up-down direction. With the first cylindrical portion 21b of the first stay 21 inserted through and fitted into the opening 22a1 of the second cylindrical portion 22a, the first stay 21 and the second stay 22 are fixed together by screw fastening or the like.

[0045] Furthermore, as shown in Figure 3, a recess 22a2 is formed in the second cylindrical portion 22a. The recess 22a2 is a recessed portion extending forward from the rear end of the second cylindrical portion 22a and is formed on the central side in the left-right direction. The recess 22a2 is not part of the material, but is a space. As will be described later, the cable 31 of the harness 30 connected to the housing 11 is inserted through the recess 22a2.

[0046] The protruding portion 22b extends from the front of the second cylindrical portion 22a in the left-right direction. In the examples shown in Figures 3 to 5, the protruding portions 22b are provided at two locations on the front of the second cylindrical portion 22a, one on the left and one on the right.

[0047] Specifically, as shown in Figure 3, the left projection 22b protrudes to the left from the left side of the front of the second cylindrical portion 22a. The right projection 22b protrudes to the right from the right side of the front of the second cylindrical portion 22a. As will be described later, a bushing assembly 22c is attached to each projection 22b.

[0048] The bushing assembly 22c is attached to the second stay 22 on the side opposite to the first stay 21. In other words, the bushing assembly 22c is attached to the front side of the second stay 22.

[0049] Specifically, as shown in Figure 3, the bush assembly 22c includes a bush 22c1 and a housing 22c2. The bush 22c1 is formed of, for example, an elastic material. This elastic material may be, for example, resin or rubber. The bush 22c1 has a cylindrical shape that extends in the vertical direction. The housing 22c2 houses the bush 22c1. The housing 22c2 is arranged coaxially with the bush 22c1 and has a substantially cylindrical shape. The bush 22c1 is fitted into the inner circumferential surface of the housing 22c2. In other words, the outer circumferential surface of the bush 22c1 is covered by the housing 22c2. The housing 22c2 is formed of, for example, a metal material such as stainless steel.

[0050] As described above, the front part of the second stay 22 is provided with two protrusions 22b, one on the left and one on the right. A bush assembly 22c is attached to each of the protrusions 22b. Therefore, bush assemblies 22c are attached to two locations on the front part of the second stay 22, one on the left and one on the right. As will be described later, each headrest shaft 2c is inserted through each bush 22c1 and fitted into place. The bush assembly 22c is fixed to the protrusions 22b, for example, by screw fastening via a mounting bracket 22d.

[0051] Here, each protrusion 22b has an elongated hole 22b1 that extends in the left-right direction. The elongated hole 22b1 penetrates the protrusion 22b in the front-rear direction. For example, a screw for fixing the bush assembly 22c to the protrusion 22b is inserted through the elongated hole 22b1. By adjusting the position of the screw along the elongated hole 22b1, the position of the bush assembly 22c can be adjusted along the elongated hole 22b1. As a result, the distance between two bush assemblies 22c can be matched to the distance between two headrest shafts 2c, so that the stay 20 can be attached to a variety of automobiles.

[0052] As shown in Figures 4 and 5, the headrest shafts 2c are attached to the bushes 22c1. Specifically, each headrest shaft 2c is inserted through and fitted into each bush 22c1. When the headrest shafts 2c are fitted into the bushes 22c1, the elastic force of the bushes 22c1 (specifically, the force that causes the bushes 22c1, which have been expanded by the headrest shafts 2c, to return to their original shape) acts on the headrest shafts 2c. This allows the bushes 22c1 to be fixed to the headrest shafts 2c.

[0053] The third stay 23 is connected to the second stay 22 and covers the portion of the second stay 22 that includes the bush assembly 22c (see Figures 4 and 5). As shown in Figure 3, the third stay 23 includes a first cover 23a, a second cover 23b, a third cover 23c, and a fourth cover 23d. The third stay 23 is formed from a material such as plastic. The third stay 23 is attached to the second stay 22 from the front so as to cover the outer surface of the second stay 22 and is fixed to the second stay 22 by screw fastening or the like.

[0054] The first cover 23a covers the front of the second stay 22. Specifically, as shown in Figure 3, the first cover 23a has a strip shape that extends in the left-right direction. As shown in Figures 4 and 5, when the second stay 22 and the third stay 23 are connected, the first cover 23a faces the front of the second stay 22 in the front-rear direction.

[0055] The second cover 23b covers the upper and lower parts of the second stay 22. Specifically, as shown in Figure 3, the second cover 23b is located on the left-right central side of the first cover 23a and has a substantially rectangular flat plate shape that extends rearward from the upper and lower ends of the first cover 23a. As shown in Figures 4 and 5, when the second stay 22 and the third stay 23 are connected, the second cover 23b faces the upper and lower parts of the second stay 22 in the vertical direction.

[0056] The third cover 23c covers the left portion of the second stay 22. Specifically, as shown in Figure 3, the third cover 23c extends rearward from the left end of the first cover 23a, with its upper and lower ends protruding to the right (for example, a shape like a flat plate bent into a U-shape). As shown in Figures 4 and 5, when the second stay 22 and the third stay 23 are connected, the third cover 23c faces the left portion of the second stay 22 in the left-right direction.

[0057] The fourth cover 23d covers the right portion of the second stay 22. Specifically, as shown in Figure 3, the fourth cover 23d extends rearward from the right end of the first cover 23a and has a shape with its upper and lower ends protruding to the left (for example, a shape like a flat plate bent into a U-shape). As shown in Figures 4 and 5, when the second stay 22 and the third stay 23 are connected, the fourth cover 23d faces the right portion of the second stay 22 in the left-right direction.

[0058] When attaching the tablet terminal 10 to the headrest shaft 2c of the seat 2, first, the tablet terminal 10, the first stay 21, and the second stay 22 are fixed to each other by screw fastening or the like. Then, with the tablet terminal 10, the first stay 21, and the second stay 22 fixed to each other, two bushings 22c1 are attached to the two headrest shafts 2c. Specifically, each headrest shaft 2c is press-fitted into each bushing 22c1. This fixes the tablet terminal 10, the first stay 21, and the second stay 22 to the headrest shaft 2c. After that, the third stay 23 is attached to the second stay 22 from the front, and the second stay 22 and the third stay 23 are fixed to each other by screw fastening or the like. This results in the state shown in Figures 4 and 5, where the tablet terminal 10 is attached to the headrest shaft 2c via the stay 20.

[0059] As described above, in the tablet terminal assembly 100 according to this embodiment, the stay 20 includes a first stay 21 attached to the back surface 11a of the housing 11 of the tablet terminal 10, and a second stay 22 connected to the first stay 21 and attached to the headrest shaft 2c of the seat 2. The first stay 21 includes a mounting portion 21a attached to the back surface 11a of the housing 11 and provided along the back surface 11a of the housing 11, and a first cylindrical portion 21b extending from the mounting portion 21a in a direction intersecting the mounting portion 21a. The second stay 22 has a second cylindrical portion 22a that fits into the first cylindrical portion 21b.

[0060] Here, if the stay 20 were a simple L-shape formed by bending a flat plate, when a load is applied to the stay 20 via the tablet terminal 10, the stay 20 would be prone to bending deformation and breakage. On the other hand, in this embodiment, the first cylindrical portion 21b of the first stay 21 extends from the mounting portion 21a in a direction intersecting the mounting portion 21a, and furthermore, the second stay 22 is fitted into the first cylindrical portion 21b. As a result, the thickness of the portion of the stay 20 that protrudes from the mounting portion 21a to which the tablet terminal 10 is attached (i.e., the first cylindrical portion 21b and the second stay 22) can be increased, thereby increasing the overall rigidity of the stay 20. Therefore, compared to the case where the stay 20 is a simple L-shape formed by bending a flat plate, when a load is applied to the stay 20 via the tablet terminal 10, or when the tablet terminal 10 moves up and down due to vibrations caused by the movement of the taxi 1, bending deformation of the stay 20 can be suppressed, and thus damage to the stay 20 can also be suppressed. Thus, according to this embodiment, deformation of the stay 20 can be suppressed. Furthermore, according to this embodiment, by increasing the overall rigidity of the stay 20, vertical movement of the tablet terminal 10 caused by vibrations from the taxi 1 in motion can be made less likely. For example, the amplitude of vertical movement of the tablet terminal 10 caused by vibrations from the taxi 1 in motion can be suppressed. As a result, further effects include suppressing damage to the tablet terminal 10 or parts connected to the tablet terminal 10 (e.g., harness 30), suppressing vertical movement of the display screen 12 so that passengers do not have difficulty viewing the display screen 12, suppressing difficulty in reading payment cards, and suppressing difficulty in reading the two-dimensional code displayed on the screen with a smartphone or the like held by a passenger.

[0061] The above describes the measures taken to suppress deformation of the stay 20. Below, other measures taken in the tablet terminal assembly 100 according to this embodiment will be described.

[0062] In this embodiment, as shown in Figures 4 and 5, the rear surface 11a of the housing 11 is provided with a plurality of linear protrusions 13 extending parallel to each other. The protrusions 13 are portions that project forward from the rear surface 11a of the housing 11. In the example of Figures 4 and 5, the rear surface 11a of the housing 11 is provided with three protrusions 13a and three protrusions 13b, which are a plurality of linear protrusions 13 extending parallel to each other. In the example of Figures 4 and 5, these multiple protrusions 13 are parallel to each other and are linear in shape. However, the multiple protrusions 13 do not have to be parallel to each other. Also, the multiple protrusions 13 only need to be linear, and may be curved, for example. The material of the protrusions 13 may be the same as the material of the housing 11. For example, the protrusions 13 may be integrally molded with the housing 11. However, the material of the protrusions 13 may be different from the material of the housing 11. For example, as will be described later, the protrusions 13 serve as an anti-slip surface, so by using a material with a higher coefficient of friction, such as resin or rubber, for the protrusions 13, the anti-slip function can be made more effective.

[0063] The three protrusions 13a are located on the upper part of the rear surface 11a of the housing 11, on the central side in the left-right direction. The three protrusions 13a are positioned above the mounting portion 21a of the first stay 21. The three protrusions 13a extend in the left-right direction. The three protrusions 13a are also arranged at equal intervals in the vertical direction. The lengths of the three protrusions 13a are the same. In the left-right direction, the positions of the left ends of the three protrusions 13a coincide with each other, and the positions of the right ends of the three protrusions 13a also coincide with each other. The shape of the cross-section perpendicular to the extension direction of the protrusions 13a is, for example, a semicircular shape.

[0064] The number of protrusions 13a may be other than three. Furthermore, multiple protrusions 13a may be arranged at unequal intervals. Also, the lengths and positions of multiple protrusions 13a in the left-right direction may differ from one another. Additionally, the shape of the cross-section perpendicular to the extension direction of the protrusions 13a may be a shape other than a semicircle (for example, a polygon).

[0065] The three protrusions 13b are located on the left side of the rear surface 11a of the housing 11, towards the center in the vertical direction. The three protrusions 13b are located to the left of the mounting portion 21a of the first stay 21. The three protrusions 13b extend in the vertical direction. The three protrusions 13b are also arranged at equal intervals in the left-right direction. The lengths of the three protrusions 13b are the same. In the vertical direction, the upper ends of the three protrusions 13b coincide with each other, and the lower ends of the three protrusions 13b also coincide with each other. The shape of the cross-section perpendicular to the extension direction of the protrusions 13b is, for example, a semicircular shape.

[0066] The number of protrusions 13b may be other than three. Furthermore, multiple protrusions 13b may be arranged at unequal intervals. Also, the lengths and vertical positions of multiple protrusions 13b may differ from one another. Additionally, the shape of the cross-section perpendicular to the extension direction of the protrusions 13b may be a shape other than a semicircle (for example, a polygon).

[0067] As described above, in the tablet terminal assembly 100 according to this embodiment, the back surface 11a of the housing 11 is provided with a plurality of linear protrusions 13 that extend parallel to each other. As mentioned above, when passengers get on or off the vehicle, they may grasp the tablet terminal 10. In that case, the passenger's hand will catch on the protrusions 13, preventing the passenger's hand from slipping off the tablet terminal 10. In this way, the protrusions 13 perform an anti-slip function, thereby improving passenger safety. Furthermore, during the distribution process of the tablet terminal 10, when a worker removes the tablet terminal 10 from the packaging box, the worker's hand will be prevented from slipping off the tablet terminal 10. In this way, the protrusions 13 perform an anti-slip function, thereby preventing the tablet terminal 10 from falling.

[0068] Furthermore, in this embodiment, a portion of the harness 30 connected to the tablet terminal 10 is covered by the stay 20 from the opposite side (i.e., the front side) from the housing 11 side (i.e., the tablet terminal 10 side). In the taxi 1, the tablet terminal 10 is connected to other devices via the harness 30. The tablet terminal 10 then communicates various information with the other devices via the harness 30.

[0069] As shown in Figure 5, a connector 11b is provided on the back surface 11a of the housing 11 of the tablet terminal 10. The connector 11b is provided in a part of the back surface 11a that is not covered by the mounting portion 21a of the first stay 21. In the example in Figure 5, the connector 11b is provided below the stay 20 on the back surface 11a. The harness 30 is then connected to the connector 11b of the housing 11. Specifically, the harness 30 includes a cable 31 and a connector 32. The connector 32 is provided at the end of the cable 31 and is connected to the connector 11b of the housing 11. The connector 32 can be connected to the connector 11b by pushing the connector 32 from the front to the rear relative to the connector 11b. For example, the connector 32 is a male connector (i.e., a connector with pins) and the connector 11b is a female connector (i.e., a connector into which pins are inserted). In the example in Figure 5, the connector 32 is located below the stay 20. The cable 31 extends upward from the connector 32.

[0070] Here, the cable 31 passes through the stay 20 in the vertical direction, passing through the recess 21b2 of the first cylindrical portion 21b of the first stay 21 and the recess 22a2 of the second cylindrical portion 22a of the second stay 22. Therefore, the portion of the cable 31 that is inserted into the recesses 21b2 and 22a2 is covered from the front by the first stay 21 and the second stay 22. In other words, the front part of the portion of the cable 31 that is inserted into the recesses 21b2 and 22a2 faces the first stay 21 and the second stay 22 in the front-rear direction.

[0071] As described above, in the tablet terminal assembly 100 according to this embodiment, a harness 30 is connected to the back surface 11a of the housing 11, and at least a portion of the harness 30 is covered by a stay 20 from the side opposite to the housing 11 (i.e., the front side). However, due to various factors, the connector 32 may come off the connector 11b of the housing 11, and the harness 30 may come out of the tablet terminal 10. Examples of such factors include passengers unintentionally grasping the cable 31, and vibrations caused by the movement of the taxi 1. In contrast, according to this embodiment, since at least a portion of the harness 30 is covered by the stay 20 from the front side, when a force acting on the harness 30 in the direction that would pull it out (i.e., the forward direction) is applied to the harness 30, the harness 30 can be supported by the stay 20 from the front side, thus suppressing the situation in which the harness 30 comes out of the tablet terminal 10. Furthermore, as a result, when connector 11b and connector 32 are connected, even if someone tries to remove connector 32, the harness 30 will come into contact with the stay 20 before the connections of the pins of connector 32 are released, thus preventing all the connections of the pins of connector 32 from being released. Therefore, for example, hot-swapping can be suppressed.

[0072] In the above example, only a portion of the cable 31 is covered by the stay 20 from the side opposite the housing 11 (i.e., the front). However, the entire cable 31 may be covered by the stay 20 from the side opposite the housing 11 (i.e., the front). Also, the connector 32 of the harness 30 may be covered by the stay 20 from the side opposite the housing 11 (i.e., the front). Furthermore, the entire harness 30 may be covered by the stay 20 from the side opposite the housing 11 (i.e., the front).

[0073] [3. Summary] As described above, the stay 20 according to this embodiment is a stay 20 for attaching an object (a tablet terminal 10 in the above example) to a seat 2 in the interior of an automobile (a taxi 1 in the above example), and comprises a first stay 21 attached to the back of the object (the back 11a of the housing 11 of the tablet terminal 10 in the above example), and a second stay 22 connected to the first stay 21 and attached to the headrest shaft 2c of the seat 2. The first stay 21 includes a mounting portion 21a attached to the back of the object and provided along the back of the object, and a first cylindrical portion 21b extending from the mounting portion 21a in a direction intersecting the mounting portion 21a, and the second stay 22 has a second cylindrical portion 22a fitted into the first cylindrical portion 21b. As a result, the thickness of the portion of the stay 20 that protrudes from the mounting portion 21a to which the object is attached (i.e., the first cylindrical portion 21b and the second stay 22) can be increased, thereby increasing the overall rigidity of the stay 20. Therefore, compared to the case where the stay 20 is a simple L-shape formed by bending a flat plate, when a load is applied to the stay 20 via the object, or when the object moves up and down due to vibrations caused by the vehicle's movement, bending deformation of the stay 20 can be suppressed, and thus damage to the stay 20 can also be suppressed. In this way, deformation of the stay 20 can be suppressed according to this embodiment. Furthermore, according to this embodiment, by increasing the overall rigidity of the stay 20, vertical movement of the object caused by vibrations caused by the vehicle's movement can be made less likely. For example, the amplitude of vertical movement of the object caused by vibrations caused by the vehicle's movement can be suppressed. As a result, the further effects described above can also be achieved.

[0074] In the stay 20 according to this embodiment, a bush 22c1 is attached to the second stay 22 on the side opposite to the first stay 21, and the headrest shaft 2c is attached to the bush 22c1. This allows for the proper attachment of the object (in the above example, the tablet terminal 10) to the headrest shaft 2c via the stay 20.

[0075] The stay 20 according to this embodiment has a third stay 23 that is connected to the second stay 22 and covers the portion of the second stay 22 that includes the bush 22c1. By covering the side of the second stay 22, such as the portion of the second stay 22 that includes the bush 22c1 (for example, the front surface of the second stay 22), with the third stay 23, the appearance of the stay 20 can be improved.

[0076] In the stay 20 according to this embodiment, the back surface of the object (in the above example, the back surface 11a of the housing 11 of the tablet terminal 10) is provided with a plurality of linear protrusions 13 that extend parallel to each other. As a result, the protrusions 13 can perform an anti-slip function. Therefore, it is possible to prevent the passenger's hand from slipping against the object (in the above example, the tablet terminal 10) when grasping it, thereby improving passenger safety. In addition, it is possible to prevent the worker's hand from slipping against the object when removing it from the packaging box, thereby preventing the object from falling.

[0077] In the stay 20 according to this embodiment, a harness 30 including a cable 31 and a connector 32 is connected to the back of the object (in the above example, the back 11a of the housing 11 of the tablet terminal 10), and at least a portion of the harness 30 is covered by the stay 20 from the side opposite to the object (in the above example, the tablet terminal 10). As a result, when a force acting on the harness 30 in the direction of pulling it out is applied to the harness 30, the harness 30 can be supported by the stay 20, thereby preventing the harness 30 from coming out of the object. Furthermore, as a result, when the connector on the object side (in the above example, connector 11b) and the connector 32 are connected, even if someone tries to pull out the connector 32, the harness 30 will come into contact with the stay 20 before the connections of the pins of the connector 32 are released, so that the connections of all the pins of the connector 32 are not released. Therefore, for example, hot-swapping can also be suppressed.

[0078] Preferred embodiments of the present invention have been described above with reference to the attached drawings, but it goes without saying that the present invention is not limited to these embodiments. It is clear to those skilled in the art that various modifications or alterations can be conceived within the scope of the claims, and these will naturally also fall within the technical scope of the present invention.

[0079] The above example describes an instance where the object attached to the headrest shaft 2c via the stay 20 is a tablet terminal 10. However, the object is not limited to a tablet terminal 10. For example, the object may be an L-shaped stand used by passengers to place information processing devices such as smartphones or books.

[0080] In the above, examples of the shape of the stay 20 are shown in Figures 3 to 5. However, the shape of the stay 20 is not limited to the examples shown in Figures 3 to 5.

[0081] For example, the above description illustrates an example in which the mounting portion 21a of the first stay 21 has a substantially flat shape. However, the thickness of the mounting portion 21a of the first stay 21 does not have to be uniform. Also, the mounting portion 21a of the first stay 21 may have a partially or entirely hollow shape.

[0082] Furthermore, for example, in the above description, an example was described in which the outer shape of the mounting portion 21a of the first stay 21 is substantially rectangular, having sides in the left-right direction and sides in the up-down direction. However, the outer shape of the mounting portion 21a of the first stay 21 is not limited to the shape described above.

[0083] Furthermore, for example, the position and shape of the opening 21a1 in the mounting portion 21a of the first stay 21 were described in the above as shown in Figures 3 to 5. However, the position and shape of the opening 21a1 in the mounting portion 21a of the first stay 21 are not limited to the examples shown in Figures 3 to 5.

[0084] Furthermore, for example, the above description illustrates an example in which the first cylindrical portion 21b extends forward from the lower end of the mounting portion 21a. However, the first cylindrical portion 21b may extend from a position other than the lower end of the mounting portion 21a (for example, towards the center in the vertical direction). Also, the first cylindrical portion 21b may extend in a direction intersecting the mounting portion 21a, or in a direction not perpendicular to the mounting portion 21a.

[0085] Furthermore, for example, the shape of the first cylindrical portion 21b when viewed in the extending direction of the first cylindrical portion 21b was described using examples shown in Figures 3 to 5. However, the shape of the first cylindrical portion 21b when viewed in the extending direction of the first cylindrical portion 21b is not limited to the examples shown in Figures 3 to 5.

[0086] Furthermore, for example, the above description illustrates an example in which the cable 31 is inserted through the recess 21b2 in the first cylindrical portion 21b of the first stay 21 and the recess 22a2 in the second cylindrical portion 22a of the second stay 22. However, instead of the recesses 21b2 and 22a2, through holes may be provided in the first cylindrical portion 21b of the first stay 21 and the second cylindrical portion 22a of the second stay 22, respectively, and the cable 31 may be inserted through these through holes. Alternatively, the cable 31 may pass through other members of the stay 20 instead of, or in addition to, the first stay 21 and the second stay 22.

[0087] Furthermore, for example, the above description illustrates an example in which the second cylindrical portion 22a of the second stay 22 is fitted to the outer surface of the first cylindrical portion 21b of the first stay 21. However, the second cylindrical portion 22a of the second stay 22 may be fitted to the inner surface of the first cylindrical portion 21b of the first stay 21 (for example, the inner circumferential surface of the opening 21b1 of the first cylindrical portion 21b).

[0088] Furthermore, for example, the above describes an example in which the stay 20 is attached to the headrest shaft 2c by a bush 22c1. However, the stay 20 may also be attached to the headrest shaft 2c by mechanical elements other than the bush 22c1.

[0089] Furthermore, for example, the above description illustrates an example in which the stay 20 has a third stay 23. However, the third stay 23 may be omitted from the stay 20.

[0090] Furthermore, for example, the above description illustrates an example in which three linear protrusions 13a and three protrusions 13b are provided on the back surface 11a of the housing 11, extending parallel to each other. However, both or one of the three protrusions 13a and three protrusions 13b may be omitted from the tablet terminal 10. In addition, multiple linear protrusions 13 extending parallel to each other may be provided on the back surface 11a of the housing 11 at locations different from the installation positions of the three protrusions 13a and three protrusions 13b.

[0091] Furthermore, for example, the above description illustrates an example in which at least a portion of the harness 30 connected to the tablet terminal 10 is covered by the stay 20 from the side opposite to the housing 11. However, it is not necessary for the entire harness 30 connected to the tablet terminal 10 to be covered by the stay 20 from the side opposite to the housing 11. [Explanation of Symbols]
