[Technical field]

[0001] The present invention relates to a connecting structure for attaching terminals to each other. [Background technology]

[Prior art documents] [Patent documents]

[0003] [Patent Document 1] International Publication No. 2023 / 188511 Summary of the Invention [Problem to be solved by the invention]

[0004] If there is a device that allows a user to complete not only image data and location data acquisition but also data analysis on a portable terminal, the user can, for example, acquire the data while walking around, analyze the data on the spot, generate a three-dimensional location space on the spot, and grasp the situation on the spot, which is highly convenient. Here, when the above-mentioned portable terminal is composed of separate terminals such as a portable terminal that acquires location data (location acquisition terminal) and a terminal that analyzes data (information processing terminal), a connecting structure is required to integrate the two terminals. Here, for example, a structure that employs an elastic member such as a spring or a structure that connects the magnet alone can be considered for the connecting part in the connecting structure, but if a spring or the like is employed, the mechanical structure becomes complicated and there is a high possibility that the spring will break after long-term use, and further, although a magnet alone is simple, the terminal easily hits something when the user is moving around the site and the connection is easily released.

[0005] An object of the present application is to provide a more reliable connection structure between terminals. [Means for solving the problem]

[0006] According to the present invention, there is provided a connecting structure for attaching a position acquisition terminal to an information processing terminal, the connecting structure comprising a first connecting member and a second connecting member, the first connecting member being provided directly or indirectly on the position acquisition terminal and having a first connecting portion which is one of a protrusion and an insertion groove, the second connecting member being provided directly or indirectly on the information processing terminal and having a second connecting portion which is the other of the protrusion and the insertion groove, the first connecting member and the second connecting member being configured to transition from an unconnected state to a connected state by being rotated relative to one another, the unconnected state being a state in which the protrusion is located at the entrance of the insertion groove and the first connecting portion and the second connecting portion are unconnected, and the connected state being a state in which the protrusion is inserted into the insertion groove and the protrusion is accommodated in the insertion groove, thereby connecting the first connecting portion and the second connecting portion.

[0007] According to the present invention, the first and second connecting members are configured to transition from a non-connected state to a connected state by being rotated relative to one another, and the connected state is a state in which the first and second connecting parts are connected by inserting the protrusion into the insertion groove and receiving the protrusion in the insertion groove. Therefore, the present invention does not use springs, magnets, or the like for connection, and the reliability of the connection between the terminals is improved.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0009] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. Various characteristic features shown in the following embodiment can be combined with each other. Also, each characteristic feature can be an invention independently.

[0010] 1. Overall configuration of the embodiment The connecting structure of the embodiment comprises a first connecting member 100 (see FIG. 3A) and a second connecting member 200 (see FIG. 2B), and the first connecting member 100 and the second connecting member 200 are configured to be connectable to each other so that a position acquisition terminal 3 can be attached to the information processing terminal 1.

[0011] 1-1. Information processing terminal 1 As shown in FIGS. 1A to 1C, the information processing terminal 1 is a portable terminal (mobile terminal), and for example, a smartphone or a tablet terminal can be adopted. The information processing terminal 1 may be a dedicated device, or may be a general-purpose device that is used by downloading a predetermined surveying application instead of a dedicated device. In addition, in one example of the embodiment, the information processing terminal 1 includes a camera 1a so as to acquire image data. Although not shown, the information processing terminal 1 may have a function related to LiDAR (Light Detection And Ranging) and include a corresponding device.

[0012] In the embodiment, the information processing terminal 1 is accommodated in a case 2. In the embodiment, the case 2 has a back surface 2a to which the second connecting member 200 is attached, and an accommodating section 2b that accommodates the information processing terminal 1. In the embodiment, the second connecting member 200 is attached to the back surface 2a of the case 2 by a means such as adhesion, but this is not limited to this, and for example, the second connecting member 200 may be attached directly to the back surface of the information processing terminal 1. In this case, the case 2 is not necessary.

[0013] 1-2. Location acquisition terminal 3 The position acquisition terminal 3 is also a portable terminal like the information processing terminal 1. As shown in FIG. 3A and FIG. 3B, the position acquisition terminal 3 has a housing 3a, an antenna 3b, a circuit component 3c, and a battery 3d. As shown in FIG. 3A, a first connecting member 100 is provided on the upper surface of the housing 3a, and a detachable antenna 3b is provided on the housing 3a, as shown in FIG. 1A. As shown in FIG. 3A and FIG. 3B, the housing 3a has a first member 3a1 and a second member 3a2, and the circuit component 3c and the battery 3d are accommodated in the internal space of the first member 3a1 and the second member 3a2. In one embodiment, the first member 3a1 is a plate-shaped cover and constitutes the front (upper surface) of the position acquisition terminal 3. The second member 3a2 has a bottom surface and a side surface standing upright from the bottom surface, and the circuit component 3c and the battery 3d can be arranged thereon. The first member 3a1 is attached to the second member 3a2 to form the internal space. The means for connecting the first member 3a1 and the second member 3a2 is not particularly limited, and an engagement structure or adhesion can be used. As the engagement structure, for example, an engagement structure using claws or an engagement structure using unevenness can be used.

[0014] In the embodiment, the first connecting member 100 constitutes at least a part of the housing 3a of the position acquisition terminal 3. In other words, the first connecting member 100 is formed on the housing 3a itself. Specifically, a shape corresponding to the first connecting member 100 is formed on the upper surface of the first member 3a1 of the housing 3a. This makes it possible to make the terminal in a state where the position acquisition terminal 3 is attached to the information processing terminal 1 (hereinafter also referred to as the terminal in the combined state) thinner.

[0015] The circuit component 3c can be configured, for example, by a circuit board or the like for making the position acquisition terminal 3 function. The battery 3d can supply power for making the position acquisition terminal 3 function, such as making the circuit of the circuit component 3c function. The battery 3d shown in FIG. 1B is disposed at a position corresponding to the position where the first connecting member 100 is formed. In other words, the battery 3d is disposed on the rear side of the first connecting member 100. That is, the position where the first connecting member 100 is formed is a position where the height of the internal space of the housing 3a is low, but the battery 3d is disposed at this position. Also, the circuit component 3c is disposed at a position away from the position where the first connecting member 100 is formed.

[0016] 2. Detailed explanation of the connection structure The connecting structure according to the embodiment is a connecting structure for connecting terminals to each other (a structure for connecting the position acquisition terminal 3 to the information processing terminal 1). The connecting structure according to the embodiment is composed of a first connecting member 100 and a second connecting member 200, and the first connecting member 100 and the second connecting member 200 are configured to transition from a non-connected state to a connected state by being rotated relative to each other. In addition, in the unconnected state shown in Figure 9A, the protrusion portion 10 of the first connecting member 100, which will be described later, is positioned at the entrance 20a (see Figure 8) of the insertion groove portion 20 of the second connecting member 200, and the protrusion portion 10 (first connecting portion) and the insertion groove portion 20 (second connecting portion) are in an unconnected state. In the connected state shown in FIG. 9B, the protrusion 10 is inserted into the insertion groove 20, and the protrusion 10 (first connecting portion) and the insertion groove 20 (second connecting portion) are connected to each other.

[0017] 2-1. First connecting member 100 The first connecting member 100 is provided directly or indirectly on the position acquisition terminal 3. In the embodiment, the first connecting member 100 is formed on the housing 3a of the position acquisition terminal 3 itself, and is therefore directly provided. The first connecting member 100 has a first connecting portion. Here, the first connecting portion is constituted by a protrusion 10 as shown in Figs. 3A and 3B.

[0018] As shown in FIGS. 3A and 3B, the first connecting member 100 has a protrusion 10 (first connecting portion), a recess 11, and a protruding portion 12.

[0019] 2-1-1.Protrusion 10 The protrusion 10 is a portion that is inserted into and closely engages (connects) with the insertion groove 20 serving as a second connecting portion described later. Here, closely contacting means that the surfaces of the protrusion 10 and the insertion groove 20 come into contact with each other, generating a frictional force that prevents the protrusion 10 from easily coming out of the insertion groove 20. For example, even if the attitude of the combined terminals is rotated in any direction, it is preferable that the protrusion 10 and the insertion groove 20 are closely contacted to such an extent that the engagement (connection) between the protrusion 10 and the insertion groove 20 is not loosened due to the weight of the information processing terminal 1 or the position acquisition terminal 3.

[0020] The first connecting member 100 has a plurality of protrusions 10 arranged to form a predetermined arrangement angle. The predetermined arrangement angle can be set to any angle, but is 90 degrees in one embodiment. The predetermined arrangement angle can be set to an angle that divides 360 degrees equally (for example, 90 degrees if divided into four). Specifically, the predetermined arrangement angle can be 5, 10, 15, 20, 25, 30, 35, 40, 45, 50, 55, 60, 65, 70, 75, 80, 85, 90, 95, 100, 105, 110, 115, 120, 125, 130, 135, 140, 145, 150, 155, 160, 165, 170, 175, or 180 degrees, or can be set within the range of the two values ​​listed here. In the embodiment, the first connecting member 100 has four protrusions 10. In FIG. 3A, the protrusions 10 are configured from a protrusion 10 at a position of 0 degrees, a protrusion 10 at a position of 90 degrees, which is an example of the arrangement angle described above, a protrusion 10 at a position of 180 degrees, and a protrusion 10 at a position of 270 degrees. In the embodiment, the number of protrusions 10 is four, but is not limited to this, and may be two, three, or five or more. For example, when there are two protrusions 10, they may be configured from protrusions 10 at positions facing each other (for example, 0 degrees and 180 degrees or 90 degrees and 270 degrees). When there are three protrusions 10, they may be configured from protrusions at positions of 0 degrees, 90 degrees, and 180 degrees, or from protrusions at positions of 0 degrees, 120 degrees, and 240 degrees. It should be noted that if the protrusions 10 are configured at positions of 0 degrees, 120 degrees, and 240 degrees, it will not be possible to hold the information processing terminal 1 in an orientation rotated 90 degrees as shown in Figures 1B and 1C. In addition, in the embodiment, in any connected state (in one embodiment, the connected state of FIG. 1B or the connected state of FIG. 1C), the second connecting member 200 is connected by a pair (multiple) of protrusions 10, but this is not limited thereto. In other words, instead of a pair of protrusions 10, connection may be realized by one protrusion 10, or by three or more protrusions 10 (the same applies to the insertion groove portion 20 of the second connecting member 200 described later).

[0021] As shown in Fig. 3B, the protrusion 10 is formed so as to protrude from the protrusion 10 side toward the center O. Here, the center O is a point through which a rotation axis passes when the first connecting member 100 and the second connecting member 200 rotate relatively. Note that the rotation axis described here is a virtual axis perpendicular to the paper surface of Fig. 3A. 3B, the protrusion 10 is disposed so that at least a portion thereof is embedded in the recess 11 in the height direction h. In other words, at least a portion of the protrusion 10 is located below the upper surface of the first member 3a1 of the housing 3a in the height direction h. This reduces the height of the first connecting member 100, contributing to a thinner terminal in the combined state.

[0022] 2-1-2. Recess 11 The recess 11 is formed to be recessed with respect to the upper surface of the first member 3a1. In the embodiment, the recess 11 is formed in an annular (circular ring) shape. The shape (shape in plan view) of the recess 11 is not limited to an annular (circular ring) shape, and may be a recess extending in an arc shape. An opposing surface portion 21 of the second connecting member 200 described later can be inserted into the recess 11. Specifically, the bottom portion 11a of the recess 11 forms a flat surface, and faces the opposing surface portion 21 in both the non-connected state and the connected state. By inserting the opposing surface portion 21 into the recess 11, it becomes easier to position the first connecting member 100 and the second connecting member 200. In addition, by inserting the opposing surface portion 21 into the recess 11, at least a part of the structure of the second connecting member 200 enters the recess 11, which contributes to making the terminal thinner in the combined state. A protrusion portion 10 is provided on the edge portion 11b of the recess 11. The edge 11b is an edge on the outer periphery of the recess 11. The protrusion 10 is provided on the edge 11b on the outer periphery of the recess 11, not on the edge on the inner periphery of the recess 11, so that a large distance is ensured between the protrusion 10 and the center O, making it easier to ensure the torque when connecting the first connecting member 100 and the second connecting member 200.

[0023] 2-1-3. Protruding part 12 As shown in Figs. 3A and 3B, the protruding portion 12 is provided so as to be surrounded by the recessed portion 11 of the first connecting member 100. The protruding portion 12 is a portion that is inserted into the recessed portion 25 of the second connecting member 200 described later. By inserting the protruding portion 12 into the recessed portion 25, it becomes easier to position the first connecting member 100 and the second connecting member 200. The upper surface 12a of the protruding portion 12 is disposed at a lower position than the protruding portion 10 in the height direction h. In addition, a recessed portion 12b is formed on the upper surface 12a of the protruding portion 12. In the embodiment, a plurality (four) of recessed portions 12b are formed, but this is not limited thereto, and a single recessed portion 12b may be formed, or none may be formed.

[0024] 2-2. Second connecting member 200 The second connecting member 200 is provided directly or indirectly on the information processing terminal 1. In the embodiment, the second connecting member 200 is attached to the case 2 that houses the information processing terminal 1, and is therefore provided indirectly. The second connecting member 200 has a second connecting portion. Here, the second connecting portion is formed of an insertion groove portion 20, as shown in Figs. 4A and 4B.

[0025] As shown in Figures 4A to 5, the second connecting member 200 has an insertion groove portion 20 (second connecting portion), an opposing surface portion 21, a first guide surface portion 22, a second guide surface portion 23, a return portion 24, a concave portion 25, an inclined surface portion 26, and a surface portion 27.

[0026] 2-2-1. Insertion groove portion 20 As shown in FIG. 4A to FIG. 5, the insertion groove 20 is an arc-shaped groove into which each protrusion 10 is inserted. The second connecting member 200 has a plurality of insertion grooves 20 arranged to form the predetermined arrangement angle described in the first connecting member 100. That is, the number of insertion grooves 20 is formed corresponding to the number of protrusions 10, and since there are four protrusions 10 in the embodiment, there are also four insertion grooves 20. That is, the insertion grooves 20 are composed of an insertion groove 20 at a position of 0 degrees in FIG. 6, an insertion groove 20 at a position of 90 degrees, which is an example of the arrangement angle described above, an insertion groove 20 at a position of 180 degrees, and an insertion groove 20 at a position of 270 degrees. In the embodiment, the protrusions 10 and the insertion grooves 20 are arranged at positions of 0 degrees, 90 degrees, 180 degrees, and 270 degrees. In other words, the first connecting member 100 has a plurality of first connecting parts (projections 10) arranged to form 90 degrees in the rotation direction when transitioning from the non-connected state to the connected state, and the second connecting member 200 has a plurality of second connecting parts (insertion grooves 20) arranged to form 90 degrees in the rotation direction when transitioning from the non-connected state to the connected state. This makes it possible to realize a connected state in a vertical position as shown in Fig. 1B, and a connected state in a horizontal position as shown in Fig. 1C. In particular, in the horizontal position, objects displayed on the display screen of the information processing terminal 1 can be displayed wide, improving user convenience.

[0027] The insertion groove 20 is formed, for example, on the outer circumferential edge of the second connecting member 200. A surface portion 27 and an inclined surface portion 26 are disposed on an extension of the insertion groove 20. Specifically, as shown in Fig. 6, the insertion groove 20, the surface portion 27, and the inclined surface portion 26 are disposed so as to be aligned in the circumferential direction (clockwise) on the outer circumferential edge of the second connecting member. In addition, in the non-connected state, each protrusion 10 is located on each surface portion 27, and as the first connecting member 100 and the second connecting member 200 rotate relative to each other, each protrusion 10 slides along each surface portion 27 and is then inserted into each insertion groove portion 20, thereby reaching the connected state.

[0028] Here, the vertical width of the insertion groove 20 is x, and the vertical width of the protrusion 10 is y. In this case, x is 0.80y, 0.85y, 0.90y, 0.95y, y, 1.05y, 1.10y, 1.15y, 1.20y, and may be within a range between any two of the numerical values ​​exemplified here. The width x is the width of the space into which the protrusion 10 fits, and corresponds to the distance between the bottom surface Sf3 and the top surface Sf4 in FIG. 8.

[0029] 2-2-2. Opposing surface part 21 As shown in Fig. 4A and Fig. 4B, the facing surface portion 21 is a portion that is disposed opposite the bottom portion 11a of the recess 11 in the unconnected state. In the embodiment, the facing surface portion 21 is disposed opposite the bottom portion 11a even in the connected state. The facing surface portion 21 is formed on the upper portion of the insertion groove portion 20. As shown in Fig. 7A, in the embodiment, the upper surface of the facing surface portion 21 is disposed at the highest position in the second connecting member 200.

[0030] The opposing surface portions 21 are formed in a number corresponding to the insertion groove portions 20. In the embodiment, since there are four insertion groove portions 20, there are also four opposing surface portions 21.

[0031] The opposing surface portion 21 is formed with the word "LOCK" and an arrow, but it is optional whether or not to form these. The arrow indicates the rotation direction of the first connecting member 100 when the first connecting member 100 and the second connecting member 200 are connected. An inclined surface portion 26 is connected to the end portion of the opposing surface portion 21 (the circumferential end portion of the outer circumferential edge portion of the second connecting member 200).

[0032] 2-2-3. First guide surface section 22 4A, 4B, and 6, the first guide surface portion 22 has a function of guiding the position of the protrusion 10 to a non-connected position when the first connecting member 100 and the second connecting member 200 are brought close to each other. Here, the non-connected position to which the protrusion 10 is guided can be defined as, for example, the position of the surface portion 27 or the position of the entrance 20a of the insertion groove portion 20 (see FIG. 8).

[0033] As shown in FIG. 6, the first guide surface portion 22 is formed outside the concave portion 25 in the radial direction. Further, the first guide surface portion 22 is connected to the surface portion 27. The first guide surface portion 22 has a first curved surface 22a. The first curved surface 22a is formed to be inclined as it goes from the central side to the peripheral side of the second connecting member 200. In other words, the first curved surface 22a is inclined downward as it goes from the inside to the outside in the radial direction.

[0034] 2-2-4. Second guide surface portion 23 As shown in FIGS. 5 and 7B, the second guide surface portion 23 has a function of smoothly guiding the protrusion 10 located on the surface portion 27 into the insertion groove portion 20 when transitioning from the unconnected state to the connected state. The second guide surface portion 23 has a second curved surface 23a. The second curved surface 23a is formed such that the width of the insertion groove portion 20 becomes narrower as it goes deeper into the insertion groove portion 20 in the radial direction of the second connecting member 200. And the second curved surface 23a is provided on the entrance 20a side of the insertion groove portion 20 so as to guide the protrusion 10 to the depth of the insertion groove portion 20.

[0035] 2-2-5. Return portion 24 As shown in FIGS. 4A, 4B, 5, 7B, and 8, the second connecting member 200 has a return portion 24. The return portion 24 has a convex portion 24a provided on the entrance 20a side of the insertion groove portion 20. In the embodiment, the return portion 24 further has a groove portion 24b at the back of the convex portion in the insertion direction of the protrusion 10. As shown in FIG. 8, the top surface Sf2 of the convex portion 24a of the return portion 24 is disposed at a position protruding above the surface Sf1 of the surface portion 27 and the lower surface Sf3 of the insertion groove portion 20. Note that the surface Sf1 is the upper surface of the surface portion 27, and the lower surface Sf3 is the lower surface of the insertion groove portion 20. The lower surface Sf3 faces the top surface Sf4 of the insertion groove portion 20. In the embodiment, the return portion 24 is formed on the lower surface Sf3, but it may be formed on the top surface Sf4.

[0036] Since the second connecting member 200 is formed with the return portion 24, when the first connecting member 100 and the second connecting member 200 are rotated relative to one another to insert the protrusion 10 into the insertion groove portion 20, the return portion 24 creates a slight rotational resistance, and the protrusion 10 is pressed into the insertion groove portion 20. The protrusion 10 rides over the return portion 24 and fits into the insertion groove portion 20, so that the protrusion 10 is prevented from easily coming out of the insertion groove portion 20 even if the user holds the combined terminal and shakes it.

[0037] 2-2-6. Concave portion 25 As shown in FIG. 4B, the protruding portion 12 of the first connecting member 100 is inserted into the recessed portion 25 in the unconnected state and the connected state. The recessed portion 25 has a substantially circular shape in a plan view. A protruding portion 25b is formed on a bottom portion 25a of the recessed portion 25. The protruding portion 25b may function as a marker (in this case, the protruding portion 25b is not inserted into the recessed portion 12b of the first connecting member 100). The protruding portion 25b may be inserted into the recessed portion 12b of the protruding portion 12 of the first connecting member 100 described above to engage with the recessed portion 12b, thereby increasing the connecting force between the first connecting member 100 and the second connecting member 200.

[0038] 2-2-7.Slope section 26 The inclined surface portion 26 has a function of facilitating separation of the first connecting member 100 and the second connecting member 200. The inclined surface portion 26 has an inclined surface 26a. This inclined surface 26a is a surface along which the protrusion 10 slides after the protrusion 10 moves from a connected state position to a non-connected state position.

[0039] 8, arrow Ar1 indicates the movement direction of protrusion 10 when moving from the non-connected position to the connected position, and arrow Ar2 indicates the movement direction of protrusion 10 when moving from the connected position to the non-connected position. When protrusion 10 moves from the connected position to the non-connected position, protrusion 10 faces inclined surface portion 26 shown in FIG. 6. Here, protrusion 10 slides up on inclined surface 26a, so that first connecting member 100 and second connecting member 200 are separated, and therefore first connecting member 100 and second connecting member 200 can be smoothly separated.

[0040] 2-2-8. Surface part 27 The surface portion 27 is a flat surface formed on the outer circumferential edge portion of the second connecting member 200. The surface portion 27 is formed so as to extend in an arc shape on the outer circumferential edge portion of the second connecting member 200. On the outer circumferential edge portion of the second connecting member 200, one end of the surface portion 27 is connected to the insertion groove portion 20, and the other end is connected to the inclined surface portion 26. In addition, the first guide surface portion 22 is disposed on the inner side of the surface portion 27 in the radial direction.

[0041] 3. Operation Description 3-1. Explanation of how to connect The user brings the first connecting member 100 shown in FIG. 3A and the second connecting member 200 shown in FIG. 2B close to each other. Then, as shown in FIG. 9A, the user places the protrusion 10 of the first connecting member 100 at the position of the surface portion 27 (unconnected state). At this time, although not shown by a symbol in FIG. 9A, the opposing surface portion 21 of the second connecting member 200 is inserted into the recessed portion 11 of the first connecting member 100, and the protruding portion 12 of the first connecting member 100 is inserted into the recessed portion 25 of the second connecting member 200. In addition, the position of the convex portion 25b is deviated from the position of the recessed portion 12b.

[0042] When the user rotates the first connecting member 100 and the second connecting member 200 relative to each other, the protrusion 10 enters the insertion groove 20 from the entrance 20a of the insertion groove 20. That is, the protrusion 10 relatively rotates in the direction of the arrow Ar3 in FIG. 9A, enters the insertion groove 20, and transitions from the state shown in FIG. 9A to the state shown in FIG. 9B. Here, the protrusion 10 climbs over the return portion 24 (see FIG. 8) and reaches the insertion groove 20, and is accommodated in the insertion groove 20. The positions of the convex portion 25b and the concave portion 12b coincide with each other. In this way, the first connecting member 100 and the second connecting member 200 reach a connected state.

[0043] 9B, it is preferable that at least a part of the surface of the protrusion 10 in the insertion groove 20 is in strong contact (close contact) with at least a part of the surface of the insertion groove 20. This increases the close contact between the protrusion 10 and the insertion groove 20, and effectively prevents the protrusion 10 from easily coming out of the insertion groove 20.

[0044] In the embodiment, a connection state as shown in Fig. 1B (an example of a first connection state) and a connection state as shown in Fig. 1C (an example of a second connection state) can be realized. In other words, the connection state of the connection structure according to the embodiment includes the connection state as shown in Fig. 1B and the connection state as shown in Fig. 1C. Here, the protrusion 10 (first connecting portion) and the insertion groove 20 (second connecting portion) in the connected state as shown in FIG. 1C are arranged at a 90 degree rotational angle from the protrusion 10 (first connecting portion) and the insertion groove 20 (second connecting portion) in the connected state as shown in FIG. 1B. In the connected state as shown in FIG. 1C, when the position acquisition terminal 3 is held vertically, the display screen of the information processing terminal 1 can be displayed wider than in the connected state as shown in FIG. 1B (the vertical screen display can be changed to the horizontal screen display), which can improve the user's convenience. In other words, the first connecting member 100 and the second connecting member 200 can be switched from the connected state as shown in FIG. 1B to the connected state as shown in FIG. 1C, which can change the display screen of the information processing terminal 1 from the vertical screen display to the horizontal screen display, which can improve the user's convenience. In one example of the embodiment, the information processing terminal 1 is equipped with various sensors capable of recognizing the up and down directions, and has an automatic display screen rotation function that can switch between the display screen when the information processing terminal 1 is in portrait orientation and the display screen when the information processing terminal 1 is in landscape orientation.

[0045] 3-2. How to release the connection To change from the connected state to the unconnected state, the user rotates the first connecting member 100 and the second connecting member 200 relatively in the opposite direction to that described in section 3-1 (the opposite direction to the direction of the arrow Ar3). As a result, the protrusion 10 climbs over the return portion 24 again and reaches the surface portion 27. In other words, it returns from the connected state to the unconnected state. Then, the protrusion 10 further rises while contacting the inclined surface portion 26 (inclined surface 26a), and accordingly the opposing distance between the first connecting member 100 and the second connecting member 200 increases, and the first connecting member 100 and the second connecting member 200 are separated.

[0046] 4. Other embodiments In the embodiment, the first connecting member 100 is formed on the housing 3a itself, but the present invention is not limited to this. Although the thickness will increase, the housing 3a and the first connecting member 100 may be separate bodies, and the first connecting member 100 may be attached to the housing 3a (first member 3a1). In the embodiment, the first connecting portion of the first connecting member 100 is described as a protrusion portion 10 (i.e., a convex structure), and the second connecting portion of the second connecting member 200 is described as an insertion groove portion 20 (i.e., a concave structure), but this is not limited to this, and the convex-convex relationship between the two may be reversed, and the first connecting portion may be the insertion groove portion 20 and the second connecting portion may be the protrusion portion 10.

[0047] As shown in FIGS. 10A to 10C, the first connecting member 100 may have first magnet members M11 to M14, and the second connecting member 200 may have second magnet members M21 to M24. The first magnet members M11 to M14 may be disposed in a recess (not shown) formed on the surface of the protruding portion 12 of the first member 3a1 of the housing 3a, or may be disposed inside the housing 3a. The first magnet members M11 to M14 are disposed at positions of 90 degrees, 0 degrees, 270 degrees, and 180 degrees, respectively. Note that this arrangement angle can be changed according to the predetermined arrangement angles of the protruding portion 10 and the insertion groove portion 20 described above (the same applies to the second magnet member described below). The second magnet members M21 to M24 may be disposed, for example, in recesses 28 formed in the lower surface of the second connecting member 200 shown in Fig. 5. In the connected state shown in Fig. 10B, the second magnet members M21 to M24 are disposed at positions of 90 degrees, 0 degrees, 270 degrees, and 180 degrees, respectively, shown in Fig. 10A. In the connected state shown in Fig. 10C, the second magnet members M21 to M24 are disposed at positions of 180 degrees, 90 degrees, 0 degrees, and 270 degrees, respectively, shown in Fig. 10A. In the case of the connected state shown in FIG. 10B, the first magnet member M11 and the second magnet member M21 have opposing surfaces that are, for example, N poles or S poles so that a magnetic force that attracts each other is generated. For example, if the opposing surface of the first magnet member M11 is N pole, the opposing surface of the second magnet member M21 is S pole. Similarly, the first magnet member M12 and the second magnet member M22 have opposing surfaces that are N poles or S poles so that a magnetic force that attracts each other is generated. Furthermore, the first magnet member M13 and the second magnet member M23 have opposing surfaces that are N poles or S poles so that a magnetic force that attracts each other is generated. Furthermore, the first magnet member M14 and the second magnet member M24 have opposing surfaces that are N poles or S poles so that a magnetic force that attracts each other is generated. Here, the facing surfaces of the first magnet member M11, the first magnet member M12, the first magnet member M13, and the first magnet member M14 may alternate between N and S poles. For example, if the facing surface of the first magnet member M11 is an N pole, the facing surface of the first magnet member M12 is an S pole, the facing surface of the first magnet member M13 is an N pole, and the facing surface of the first magnet member M14 is an S pole. In this case, the facing surface of the second magnet member M21 is an S pole, the facing surface of the second magnet member M22 is an N pole, the second magnet member M23 is an S pole, and the second magnet member M24 is an N pole. By having each connecting member have a magnet (magnetic member) as in this embodiment, in the connected state shown in FIG. 10B (an example of a first connected state), the connecting force between the first connecting member 100 and the second connecting member 200 is increased by the magnetic force of attraction between the first magnet member M11 to the first magnet member M14 and the second magnet member M21 to the second magnet member M24. Furthermore, in the connected state shown in FIG. 10C (an example of the second connected state), the repulsive magnetic forces of the first magnet members M11 to M14 and the second magnet members M21 to M24 strengthen the contact force between the protrusions 10 and the insertion grooves 20 (the protrusions 10 as claws are pushed deeper into the insertion grooves 20), thereby increasing the connecting force between the first connecting member 100 and the second connecting member 200. Note that, here, it has been described that an attractive magnetic force is generated in the connected state shown in FIG. 10B, and a repulsive magnetic force is generated in the connected state shown in FIG. 10C, but the magnetic members may be arranged so that the magnetic forces are reversed (repulsive in FIG. 10B, attractive in FIG. 10C).

[0048] In the above-described embodiment of Figs. 10A to 10C, the first magnet member M11, the first magnet member M12, the first magnet member M13, and the first magnet member M14 are described as having N and S poles alternately on their opposing surfaces, but the present invention is not limited to this. The opposing surfaces may not have N and S poles alternately, but may all be N poles or all be S poles. In this case, the opposing surfaces of the second magnet member M21, the second magnet member M22, the second magnet member M23, and the second magnet member M24 have the opposite poles (all S poles or all N poles). As a result, whether in the connected state shown in Fig. 10B or in the connected state shown in Fig. 10C, an attractive magnetic force can be generated, and the connecting force between the first connecting member 100 and the second connecting member 200 is increased. 10B or 10C, the poles of the opposing surfaces may be set to generate a repulsive magnetic force (i.e., the magnetic poles of both opposing surfaces are N poles or S poles). In this case, in both connecting states, the contact force between the protrusion 10 and the insertion groove 20 is strengthened (the protrusion 10 as a claw is bitten into the insertion groove 20), and the connecting force between the first connecting member 100 and the second connecting member 200 is increased.
