[0006] Problems to be Solved by the Invention

[0007] The dual-display mobile device described in Patent Document 1 includes: a first device having a first display; and a second device having a second display.

[0008] In an electronic device in which the first device and the second device are combined, there is room for improvement in the structure for switching between a plurality of connection states.

[0009] Solutions to the Problems

[0010] The electronic device of the present disclosure includes a first device and a second device. The first device and the second device can be detachably attached. The first device includes a first front surface, a first display disposed on the first front surface, and a first connection portion. The second device includes a second front surface, a second display disposed on the second front surface, a second back surface on a side opposite to the second front surface, and a second connection portion disposed on the second back surface. The second connection portion can be connected to the first connection portion in a first direction and a second direction opposite to the first direction. In a first connection state where the second connection portion is connected to the first connection portion in the first direction, it is arranged such that the second back surface covers the first display. In a second connection state where the second connection portion is connected to the first connection portion in the second direction, it is arranged such that the second back surface does not cover the first display. Thus, a new switching structure for connection states is provided.

[0011] For example, in the case of communication between the first device and the second device, it is considered to provide external terminals on the first device and the second device respectively and connect them. However, if external terminals are provided on the first device and the second device respectively, there may be high-frequency unwanted radiation.

[0012] According to the above-described electronic device, alternatively, the first device may include a first substrate disposed inside the first device and one or more first antennas provided on the first substrate. Alternatively, the second device may include a second substrate disposed inside the second device and one or more second antennas provided on the second substrate. Alternatively, in both the first connection state and the second connection state, when looking down at the first display, the first antenna and the second antenna are disposed at overlapping positions. Alternatively, the first device and the second device can perform first wireless communication through electromagnetic field coupling between the first antenna and the second antenna. Thus, without providing external terminals, communication can be performed between the first device and the second device in either the first connection state or the second connection state. Therefore, generation of unwanted radiation at high frequencies can be suppressed. The necessity of taking countermeasures against electrostatic discharge can be reduced.

[0013] According to the above-described electronic device, alternatively, in both the first connection state and the second connection state, at least a part of the first antenna is disposed at a position overlapping with the second antenna. Thereby, the intensity of electromagnetic field coupling can be increased.

[0014] According to the above-described electronic device, alternatively, one of the first antenna and the second antenna has a first antenna portion. Alternatively, the other of the first antenna and the second antenna has a second antenna portion and a third antenna portion. Alternatively, in the first connection state, they are disposed such that the first antenna portion overlaps with the second antenna portion. Alternatively, in the second connection state, they are disposed such that the first antenna portion overlaps with the third antenna portion. Thereby, the number of antenna portions can be set to three. Compared with the case where two antenna portions are provided in the first device and two antenna portions are provided in the second device, the number of antenna portions can be reduced.

[0015] According to the above-described electronic device, alternatively, the first antenna has a first antenna portion. Alternatively, the second antenna has a second antenna portion and a third antenna portion. Alternatively, when looking down at the front surface of the first device, the first antenna portion is disposed at a position adjacent to the first connection portion. Alternatively, when looking down at the back surface of the second device, the second connection portion is disposed sandwiched between the second antenna portion and the third antenna portion.

[0016] According to the above-described electronic device, alternatively, the first device includes a first substrate disposed inside the first device and one or more first antennas provided on the first substrate. Alternatively, the second device includes a second substrate disposed inside the second device and one or more second antennas provided on the second substrate. Alternatively, one of the first antenna and the second antenna has a first antenna portion. Alternatively, the other of the first antenna or the second antenna has a second antenna portion and a third antenna portion. Alternatively, in the first connection state, the second antenna portion and the first antenna portion are arranged to overlap, and the third antenna portion does not overlap with the first antenna. Alternatively, in the second connection state, the third antenna portion and the first antenna portion are arranged to overlap, and the second antenna portion does not overlap with the first antenna.

[0017] According to the above-described electronic device, alternatively, when looking down on the first front surface, the first antenna portion is disposed at a position adjacent to the first connection portion. Alternatively, when looking down on the second back surface, the second connection portion is disposed sandwiched between the second antenna portion and the third antenna portion.

[0018] According to the above-described electronic device, alternatively, in the second connection state, the first device and the second device are connected in a state where the second display is inclined with respect to the first display.

[0019] According to the above-described electronic device, alternatively, in the first connection state, the first device and the second device are connected in a state where the second display is parallel to the first display.

[0020] According to the above-described electronic device, alternatively, the first connection portion has a first inclined surface inclined with respect to the first front surface. Alternatively, the second connection portion has a second inclined surface inclined with respect to the second back surface.

[0021] According to the above-described electronic device, in the first connection state, the angle between the first antenna and the second antenna in a cross-section perpendicular to both the first front surface and the second back surface is set as a first angle. In the second connection state, the angle between the first antenna and the second antenna in a cross-section perpendicular to both the first front surface and the second back surface is set as a second angle. The angle between the first front surface and the first inclined surface in a cross-section perpendicular to the first front surface is set as a third angle. The angle between the second back surface and the second inclined surface in a cross-section perpendicular to the second back surface is set as a fourth angle. Alternatively, the first angle and the second angle are each smaller than the sum of the third angle and the fourth angle. Thereby, the strength of electromagnetic coupling can be maintained at a relatively high level in either the first connection state or the second connection state.

[0022] According to the above-mentioned electronic device, it can also be that when the first antenna and the second antenna are electromagnetically coupled, the first device and the second device transmit and receive signals unidirectionally or bidirectionally. It can also be that the first connecting portion includes a first contact for power supply. It can also be that the second connecting portion includes a second contact for power supply. It can also be that in the first connection state and the second connection state, the first contact and the second contact are connected. Thus, power can be supplied using the first contact and the second contact. Since the terminals for power supply are not easily affected by unwanted radiation, a wired connection can be adopted.

[0023] According to the above-mentioned electronic device, it can also be that when the first device and the second device are in a separated state, the first device and the second device can perform second wireless communication. Thus, even when the first device and the second device are in a separated state, communication can be carried out between the first device and the second device.

[0024] According to the above-mentioned electronic device, it can also be that the first wireless communication in the first connection state and the second connection state is carried out through the electromagnetic coupling between the first antenna and the second antenna. It can also be that the second wireless communication in the state where the first device and the second device are separated is carried out through the electromagnetic coupling between antennas different from the first antenna and the second antenna. It can also be that the frequency band of the signal used in the first wireless communication is higher than the frequency band of the signal used in the second wireless communication. Generally speaking, as the frequency increases, higher directivity is required. By making the frequency band of the signal used in the second wireless communication lower than the frequency band of the signal used in the first wireless communication, communication between the first device and the second device can be ensured even when the first device is separated from the second device.

[0025] According to the above-mentioned electronic device, it can also be that the first connecting portion has a first receiving groove and a second receiving groove on the side opposite to the first receiving groove. It can also be that the second connecting portion has a movable hook and a fixed hook on the side opposite to the movable hook. It can also be that in the first connection state, the movable hook is not disposed in the first receiving groove, and the fixed hook is disposed in the second receiving groove. It can also be that in the second connection state, the movable hook is disposed in the second receiving groove, and the fixed hook is disposed in the first receiving groove. Thus, in the first connection state, the second device can be easily detached from the first device. On the other hand, in the second connection state, the second device can be firmly fixed to the first device.

[0026] According to the above-mentioned electronic device, alternatively, the first connecting portion has a first electrical connecting portion and a first mechanical connecting portion. Alternatively, the first electrical connecting portion is provided above or below the first display. Alternatively, the first mechanical connecting portion is arranged to sandwich the first electrical connecting portion in the longitudinal direction of the first display. Alternatively, the second connecting portion has a second electrical connecting portion and a second mechanical connecting portion. Alternatively, the second electrical connecting portion is provided above or below the second display. Alternatively, the second mechanical connecting portion is arranged to sandwich the second electrical connecting portion in the longitudinal direction of the second display. Alternatively, the first electrical connecting portion is electrically connected to the second electrical connecting portion. Alternatively, the first mechanical connecting portion is mechanically connected to the second mechanical connecting portion.

[0027] When the mechanical connecting portion is arranged to sandwich the electrical connecting portion in the width direction of the display, additional space is required in the width direction. On the other hand, there is surplus space on both sides of the electrical connecting portion in the longitudinal direction of the display. By arranging the mechanical connecting portion to sandwich the electrical connecting portion in the longitudinal direction of the display, space can be effectively utilized.

[0028] According to the above-mentioned electronic device, alternatively, the terminals of the first electrical connecting portion are arranged along the longitudinal direction of the first display. Alternatively, the terminals of the second electrical connecting portion are arranged along the longitudinal direction of the second display. When the terminals of the electrical connecting portion are arranged along the longitudinal direction of the display, compared with the case where the terminals of the electrical connecting portion are arranged along the width direction of the display, the length in the width direction of the display can be increased. As a result, the area of the display can be increased.

[0029] According to the above-mentioned electronic device, alternatively, the first device is provided with an input portion capable of performing a joystick operation or a button operation. Alternatively, the second display is provided with a touch panel capable of performing a touch input. Since the first device is provided with an input portion capable of performing a joystick operation or a button operation, appropriate operations can be performed according to the application. In addition, in the first connected state, the input portion capable of performing a joystick operation or a button operation is covered by the second device. Therefore, when carrying the electronic device, the input portion is not easily caught on other components.

[0030] According to the above-mentioned electronic device, alternatively, the first device is provided with a first housing that surrounds the first display and includes a first convex portion extending outward in the direction of the first display. Alternatively, the second device is provided with a second housing that surrounds the second display and includes a second convex portion extending outward in the direction of the second display. Alternatively, the first connecting portion is provided on the front side of the first convex portion. Alternatively, the second connecting portion is provided on the back side of the second convex portion. Thereby, the first device and the second device can be connected while increasing the sizes of the first display and the second display.

[0031] According to the above-mentioned electronic device, alternatively, the first device includes a first back surface, a first upper surface, a first lower surface, a first right side surface, and a first left side surface. Alternatively, the first back surface is on the side opposite to the first front surface. Alternatively, the first upper surface is connected to the first front surface and the first back surface. Alternatively, the first lower surface is on the side opposite to the first upper surface. Alternatively, the first right side surface is respectively connected to the first front surface, the first back surface, the first upper surface, and the first lower surface. Alternatively, the first left side surface is on the side opposite to the first right side surface. Alternatively, the second device includes a second upper surface, a second lower surface, a second right side surface, and a second left side surface. Alternatively, the second upper surface is connected to the second front surface and the second back surface. Alternatively, the second lower surface is on the side opposite to the second upper surface. Alternatively, the second right side surface is respectively connected to the second front surface, the second back surface, the second upper surface, and the second lower surface. Alternatively, the second left side surface is on the side opposite to the second right side surface. Alternatively, the first convex portion is provided on the first upper surface. Alternatively, the second convex portion is provided on the second upper surface. Alternatively, the first device includes a first input portion provided at a portion on the first right side surface side of the first convex portion and a second input portion provided at a portion of the first upper surface other than the first convex portion. Alternatively, the second device includes a third input portion provided at a portion on the second right side surface side of the second convex portion and a fourth input portion provided at a portion of the second upper surface other than the second convex portion.

[0032] Thereby, it is possible to less likely cause misoperation between the first input portion and the second input portion. Similarly, it is possible to less likely cause misoperation between the third input portion and the fourth input portion. In addition, in the second connection state, the fourth input portion of the second device is disposed at a position separated from the first device. Therefore, it is not likely to become an obstacle when operating the first input portion. In the state where the first device and the second device are separated, since the input portions are provided at a common position, the first device and the second device can be operated with the same feel. And, by sliding a finger in the horizontal direction, two different inputs can be performed.

[0033] According to the above-mentioned electronic device, alternatively, in the first connection state, in a direction perpendicular to the first front surface, the first input portion and the third input portion are arranged in parallel, and the second input portion and the fourth input portion are arranged in parallel. Thereby, it is easy for the user to remember the positions of the input portions.

[0034] According to the above-mentioned electronic device, alternatively, an input portion or a camera lens is provided on the front surface of the second convex portion. Thereby, a functional component that can be used in both the first connection state and the second connection state can be obtained. Therefore, while using the second convex portion as a connection portion, the area other than the second convex portion of the second device can be effectively utilized. For example, the second display can be enlarged.

[0035] According to the electronic device described above, alternatively, the second display may include a touch panel capable of performing a touch operation and a touch panel cover that covers the touch panel and is capable of performing an input operation on the touch panel. Alternatively, the second display may include a first tactile cue portion formed by the touch panel cover and a second tactile cue portion formed by exposing the touch panel through an opening provided in the touch panel cover. Thus, when the second display has a touch panel, the user can easily grasp the position of the second tactile cue portion.

[0063] Embodiments of the present disclosure will be described in detail with reference to the accompanying drawings. In addition, the same or corresponding parts in the drawings are denoted by the same reference numerals, and their descriptions will not be repeated.

[0064] (First Embodiment)

[0065] First, the structure of the electronic device 300 according to the first embodiment will be described.

[0066] Figure 1 It is a perspective schematic diagram showing the structure of the electronic device 300 according to the first embodiment. As Figure 1 shown, the electronic device 300 according to the first embodiment includes a first device 100 and a second device 200. The first device 100 and the second device 200 can be detachably assembled. The second device 200 can be mounted on the first device 100 and can be detached from the first device 100.

[0075] The first device 100 includes a first substrate 131 and a first antenna 132. The first substrate 131 and the first antenna 132 are respectively disposed inside the first device 100. More specifically, the first substrate 131 and the first antenna 132 are respectively disposed inside the first housing 165. The first antenna 132 is provided on the first substrate 131.

[0076] The number of the first antennas 132 is not particularly limited. The number of the first antennas 132 is, for example, one or more than two. In the electronic device 300 of the present embodiment, the number of the first antennas 132 is one. The first antenna 132 is, for example, the first antenna portion 132. When looking down at the first front surface 101, the first antenna portion 132 may also be disposed at a position adjacent to the first connection portion 120.

When looking down at the second back surface 202, the second contacts 262 are arranged along a straight line. One of the second contacts 262 is, for example, a terminal for power supply.

[0083] The second magnetic connection portion 211 is constituted by a pair of magnets, for example. The second magnetic connection portion 211 is located between the second main body portion 283 and the second front surface 201. The second magnetic connection portion 211 is disposed inside the second device 200. When looking down at the second back surface 202, the second electrical connection portion 260 is located at a position sandwiched between the pair of magnets. The second magnetic connection portion 211 can be magnetically adsorbed to the first magnetic connection portion 111 in a state separated from the first magnetic connection portion 111.

[0084] As Figure 5As shown, the second device 200 has a second substrate 231 and a second antenna 232. The second substrate 231 and the second antenna 232 are respectively disposed inside the second device 200. More specifically, the second substrate 231 and the second antenna 232 are respectively disposed inside the second housing 265. The second antenna 232 is provided on the second substrate 231.

[0085] The number of the second antennas 232 is not particularly limited. The number of the second antennas 232 is, for example, one or two or more. In the electronic device 300 of the present embodiment, the number of the second antennas 232 is two. The second antenna 232 may also have a second antenna portion 234 and a third antenna portion 236. The second substrate 231 may also have a first substrate portion 233 and a second substrate portion 235. The second antenna portion 234 is provided on the first substrate portion 233. The third antenna portion 236 is provided on the second substrate portion 235. When looking down at the second back surface 202, the second connection portion 220 may be disposed sandwiched between the second antenna portion 234 and the third antenna portion 236.

[0086] As Figure 5 shown, when looking down at the second back surface 202, the second antenna 232 may also be located at a position outside the second connection portion 220 in the left and right side surface directions. From another perspective, when looking down at the second back surface 202, the second antenna 232 may also be disposed at a position that does not overlap with the second main body portion 283. The material constituting the second housing 265 is, for example, resin. The material constituting the second main body portion 283 is not particularly limited, and may also be, for example, metal. The second antenna 232 may also be disposed in such a manner that the electromagnetic field is not blocked by the second main body portion 283.

[0087] Figure 6 is a front view schematic diagram showing the structure of the electronic device 300 in the first connection state. In the first connection state, it is disposed in such a manner that the second back surface 202 covers the first display 110. It may be disposed in such a manner that the second back surface 202 covers the entire surface of the first display 110, or may be disposed in such a manner that the second back surface 202 covers at least a part of the first display 110. The second back surface 202 is disposed to overlap with the first front surface 101. The second front surface 201 faces outward. The user can visually recognize the second display 210 disposed on the second front surface 201. In the first connection state, the Hall element 130 is disposed to overlap with the magnet portion 230. It is also possible to use the Hall element 130 to determine that the current connection state is the first connection state.

[0088] The direction from the first left side surface 106 of the first device 100 toward the first right side surface 105 corresponds to the reference direction B. When looking down at the first display 110 in the first connection state, the direction from the second left side surface 206 of the second device 200 toward the second right side surface 205 is the first direction A1. When looking down at the first display 110 in the first connection state, the first device 100 and the second device 200 are connected in such a manner that the direction from the second left side surface 206 of the second device 200 toward the second right side surface 205 is the same as the reference direction B.

[0089] Figure 7 is a schematic cross-sectional view along Figure 6 the VII-VII line of. The first connection portion 120 is connected to the second connection portion 220. Specifically, the first mechanical connection portion 180 is mechanically connected to the second mechanical connection portion 280. The first mechanical connection portion 180 has a first receiving groove 181 and a second receiving groove 182. Specifically, the first receiving groove 181 and the second receiving groove 182 are respectively provided on the back side of the first main body portion 183. The second receiving groove 182 is on the side opposite to the first receiving groove 181. The first electrical connection portion 160 is located between the first receiving groove 181 and the second receiving groove 182.

[0090] A fourth opening portion 186 is provided in the first connection portion 120. The unlocking button 191 is exposed from the fourth opening portion 186. The first device 100 has a first rotation shaft 192. The unlocking button 191 can swing about the first rotation shaft 192 as the rotation center. The fixing hook 281 is disposed in the second receiving groove 182 provided on the back side of the first main body portion 183. The unlocking button 191 may also be in contact with the fixing hook 281.

[0091] The second device 200 has a second rotation shaft 273 and a biasing member 274. The movable hook 270 can swing about the second rotation shaft 273 as the rotation center. The movable hook 270 has a first claw portion 271 and a first support portion 272. The first claw portion 271 is connected to the first support portion 272. The first support portion 272 is swingably mounted on the second rotation shaft 273. The biasing member 274 biases the movable hook 270. The biasing member 274 is, for example, a spring. The second rotation shaft 273 and the biasing member 274 are respectively disposed inside the second device 200. A part of the movable hook 270 penetrates through the third opening portion 284.

[0092] As Figure 3 and Figure 5 shown, the width (second width W2) of the movable hook 270 is larger than the width (first width W1) of the pair of first protrusions 184. Therefore, in the first connection state, the movable hook 270 jumps onto the pair of first protrusions 184. That is, the movable hook 270 is not disposed in the first receiving groove 181. As Figure 7As shown, in the first connection state, the fixed hook 281 enters the second receiving groove 182, so that the first device 100 and the second device 200 are connected. Thus, the second device 200 is installed on the first device 100. When the second device 200 is detached from the first device 100, the second device 200 is rotated in the first rotation direction R1. In this case, there is no need to press the unlocking button 191.

[0093] As Figure 7 shown, the electronic device 300 has a fourth protrusion 9. The fourth protrusion 9 can be installed on the first front surface 101 of the first device 100 or on the second back surface 202 of the second device 200. In the first connection state, the fourth protrusion 9 is located between the first front surface 101 and the second back surface 202. In the first connection state, the first front surface 101 and the second back surface 202 are substantially parallel. In the first connection state, it is also possible that the first device 100 and the second device 200 are connected in a state where the second display 210 is parallel to the first display 110. A gap is formed between the first front surface 101 and the second back surface 202 by the fourth protrusion 9. The ninth input unit 121 is separated from the second back surface 202. The fourth protrusion 9 can prevent the first device 100 and the second device 200 from shaking in the first connection state.

[0094] As Figure 7 shown, the first electrical connection part 160 is electrically connected to the second electrical connection part 260. Figure 8 It is a schematic diagram showing the relationship between the first connection part and the second connection part in the first connection state. The first connection state is a state where the second connection part 220 is connected to the first connection part 120 in the first direction A1. In the first connection state, the first contact 162 is electrically connected to the second contact 262.

[0095] As Figure 8 shown, the first contact 162 has a first terminal 162a, a second terminal 162b, and a third terminal 162c. The terminals of the first electrical connection part 160 can also be arranged along the length direction of the first display 110. The first terminal 162a is located at the position closest to the leftmost side surface of the first. The third terminal 162c is located at the position closest to the rightmost side surface of the first. The second terminal 162b is located between the first terminal 162a and the third terminal 162c. The direction from the first terminal 162a to the third terminal 162c corresponds to the reference direction B.

[0096] The second contact 262 has a fourth terminal 262a, a fifth terminal 262b, and a sixth terminal 262c. The terminals of the second electrical connection portion 260 may also be arranged along the length direction of the second display 210. The fourth terminal 262a is located at the position closest to the second left side surface. The sixth terminal 262c is located at the position closest to the second right side surface. The fifth terminal 262b is located between the fourth terminal 262a and the sixth terminal 262c. In the first connection state, the first terminal 162a, the second terminal 162b, and the third terminal 162c are electrically connected to the fourth terminal 262a, the fifth terminal 262b, and the sixth terminal 262c, respectively. In the first connection state, the second connection portion 220 is arranged relative to the first connection portion 120 in the same manner as the first direction A1 from the fourth terminal 262a toward the sixth terminal 262c. It is not limited to such a terminal arrangement. In the first connection state and the second connection state, the first contact 162 and the second contact 262 are in a connected configuration relationship. For example, for multiple terminals, other terminals may be arranged in a line-symmetric manner with the terminal arranged at the center as a reference.

[0097] Figure 9 is along Figure 6 a schematic cross-sectional view taken along the IX-IX line. As Figure 9 shown, the first magnetic connection portion 111 is arranged inside the first main body portion 183. The first main body portion 183 has a first inclined surface 187. The first inclined surface 187 is inclined with respect to the first front surface 101 of the first housing 165. The inclination angle of the first inclined surface 187 with respect to the first front surface 101 is, for example, 10°. The first magnetic connection portion 111 is arranged along the first inclined surface 187. The surface of the first magnetic connection portion 111 may also be substantially parallel to the first inclined surface 187.

[0098] Similarly, the second magnetic connection portion 211 is arranged inside the second main body portion 283. The second main body portion 283 has a second inclined surface 287. The second inclined surface 287 is inclined with respect to the second back surface 202 of the second housing 265. The inclination angle of the second inclined surface 287 with respect to the second back surface 202 is, for example, 10°. The second magnetic connection portion 211 is arranged along the second inclined surface 287. The surface of the second magnetic connection portion 211 may also be substantially parallel to the second inclined surface 287. The surface of the second magnetic connection portion 211 may also be substantially parallel to the surface of the first magnetic connection portion 111.

[0099] Figure 10This is a front view schematic diagram of the structure of the electronic device 300 indicating the second connection state. In the second connection state, it is arranged such that the second back surface 202 does not cover the first display 110. Therefore, the user can visually recognize the first display 110 and the second display 210 separately. In the second connection state, it is arranged such that a part of the first front surface 101 of the first device 100 overlaps with a part of the first back surface 102 of the second device 200. In the second connection state, it is arranged such that the Hall element 130 does not overlap with the magnet portion 230. It is also possible to use the Hall element 130 to determine that the current connection state is the second connection state.

[0100] When looking down at the first display 110 in the second connection state, the direction from the second left side surface 206 of the second device 200 towards the second right side surface 205 is the second direction A2. When looking down at the first display 110 in the second connection state, the first device 100 and the second device 200 are connected in such a way that the direction from the second left side surface 206 of the second device 200 towards the second right side surface 205 is opposite to the reference direction B.

[0101] Figure 11 is along Figure 10 the cross-sectional schematic diagram of the XI - XI line. As Figure 11 shown, in the second connection state, the movable hook 270 is arranged in the second receiving groove 182, and the fixed hook 281 is arranged in the first receiving groove 181. The movable hook 270 enters the second receiving groove 182. The fixed hook 281 enters the first receiving groove 181. Thus, the first mechanical connection portion 180 and the second mechanical connection portion 280 are mechanically fixed.

[0102] As Figure 11 shown, the first electrical connection portion 160 and the second electrical connection portion 260 are electrically connected. Specifically, in the second connection state, the first contact 162 and the second contact 262 are connected. The second back surface 202 is inclined with respect to the first front surface 101. In the second connection state, it is also possible that the first device 100 and the second device 200 are connected in a state where the second display 210 is inclined with respect to the first display 110. The inclination angle of the second back surface 202 with respect to the first front surface 101 is, for example, 20°.

[0103] Figure 12 This is a cross-sectional schematic diagram showing the state of unlocking the second connection state of the electronic device 300. As Figure 12 shown, the unlocking button 191 is pushed into the interior of the first device 100 along the third direction A3. By pushing the movable hook 270 with the unlocking button 191, the movable hook 270 is pushed out from the second receiving groove 182. As a result, the mechanical lock is released. If the second device 200 is rotated in the second rotation direction R2 in this state, the second device 200 separates from the first device 100.

[0104] Figure 13 It is a schematic diagram showing the relationship between the first connecting portion and the second connecting portion indicating the second connection state. The second connection state is a state in which the second connecting portion 220 is connected to the first connecting portion 120 in the second direction A2. The second direction A2 is opposite to the first direction A1. In the second connection state, the first terminal 162a, the second terminal 162b, and the third terminal 162c are electrically connected to the sixth terminal 262c, the fifth terminal 262b, and the fourth terminal 262a, respectively. In the second connection state, the second connecting portion 220 is arranged relative to the first connecting portion 120 in the same manner as the second direction A2 in the direction from the fourth terminal 262a toward the sixth terminal 262c.

[0105] The second terminal 162b and the fifth terminal 262b are respectively, for example, power supply terminals. In both the first connection state and the second connection state, the second terminal 162b is electrically connected to the fifth terminal 262b. The uses of the first terminal 162a and the third terminal 162c may also be the same. Similarly, the uses of the fourth terminal 262a and the sixth terminal 262c may also be the same. In this case, the same functions can be achieved respectively in the first connection state and the second connection state. In addition, in the first connection state and the second connection state, the first contact 162 and the second contact 262 may also define a corresponding plurality of telecommunication paths. The uses of the first terminal 162a, the third terminal 162c, the fourth terminal 262a, and the sixth terminal 262c are not particularly limited. For example, they may be grounding terminals, terminals for determining whether the first device 100 and the second device 200 are connected, or terminals for resetting the display.

[0106] Figure 14 It is a cross-sectional schematic diagram showing the positional relationship between the first antenna 132 and the second antenna 232 indicating the first connection state. As Figure 14 shown, in the first connection state, they are arranged such that the first antenna 132 overlaps with the second antenna portion 234 of the second antenna 232. In other words, when looking down at the first display 110 in the first connection state, the first antenna 132 and the second antenna 232 are arranged at overlapping positions. The first antenna 132 and the second antenna 232 are respectively plate-like components.

[0107] As Figure 14As shown, in a cross-section perpendicular to the first front surface 101, the first antenna 132 is substantially parallel to the first front surface 101. The first antenna 132 is inclined with respect to the first inclined surface 187. In a cross-section perpendicular to the second rear surface 202, the second antenna portion 234 of the second antenna 232 is substantially parallel to the second rear surface 202. The second antenna portion 234 of the second antenna 232 is inclined with respect to the second inclined surface 287. In the first connection state, the second antenna portion 234 of the second antenna 232 is substantially parallel to the first antenna 132.

[0108] In the first connection state, the second inclined surface 287 is in contact with the first inclined surface 187. The angle between the first front surface 101 and the first inclined surface 187 in a cross-section perpendicular to the first front surface 101 is defined as the third angle θ3. The third angle θ3 is, for example, 10°. The angle between the second rear surface 202 and the second inclined surface 287 in a cross-section perpendicular to the second rear surface 202 is defined as the fourth angle θ4. The fourth angle θ4 is, for example, 10°.

[0109] Figure 15 It is a cross-sectional schematic diagram showing the positional relationship between the first antenna 132 and the second antenna 232 in the second connection state. As Figure 15 shown, in the second connection state, the first antenna portion 132 of the first antenna 132 and the third antenna portion 236 of the second antenna 232 are arranged in an overlapping manner. In other words, when looking down at the first display 110 in the second connection state, the first antenna 132 and the second antenna 232 are arranged at overlapping positions. As described above, in both the first connection state and the second connection state, at least a part of the first antenna 132 is arranged at a position overlapping with the second antenna 232.

[0110] As Figure 15 shown, in the second connection state, the third antenna portion 236 of the second antenna 232 is inclined with respect to the first antenna 132. In a cross-section perpendicular to both the first front surface 101 and the second rear surface 202, the inclination angle (second angle θ2) of the third antenna portion 236 of the second antenna 232 with respect to the first antenna 132 is, for example, 20°. In the second connection state, the second inclined surface 287 is in contact with the first inclined surface 187.

[0111] In Figure 14 and Figure 15In the above description, the case where the first inclined surface 187 and the second inclined surface 287 are provided is described. However, the first inclined surface 187 may not be provided at the first mechanical connection portion 180, and the second inclined surface 287 may not be provided at the second mechanical connection portion 280. Specifically, the first mechanical connection portion 180 and the second mechanical connection portion 280 may be connected in parallel to each other. In this case, the first device 100 and the second device 200 may be parallel to each other, or one of the first device 100 and the second device 200 may be inclined with respect to the other of the first device 100 and the second device 200.

[0112] In the above description, the structure in which the first antenna 132 has one antenna portion and the second antenna 232 has two antenna portions is described. However, the present disclosure is not limited to this structure. In another embodiment of the electronic device 300, the first antenna 132 may have two antenna portions and the second antenna 232 may have one antenna portion. Specifically, the second antenna 232 may also have the first antenna portion. The first antenna 132 may also have the second antenna portion and the third antenna portion. In the first connection state, they may be arranged such that the first antenna portion overlaps the second antenna portion. In the second connection state, they may be arranged such that the first antenna portion overlaps the third antenna portion. In yet another embodiment of the electronic device 300, the first antenna 132 may have two antenna portions and the second antenna 232 may have two antenna portions.

[0113] In both the first connection state and the second connection state, the first device 100 and the second device 200 can perform the first wireless communication through the electromagnetic field coupling between the first antenna 132 and the second antenna 232. When the first antenna 132 and the second antenna 232 are electromagnetically coupled, the first device 100 and the second device 200 may also transmit and receive signals bidirectionally. The second device 200 may also unidirectionally receive the signals transmitted by the first device 100. The first device 100 may also unidirectionally receive the signals transmitted by the second device 200. Neither the first antenna 132 nor the second antenna 232 is particularly limited. For example, they are 60 GHz millimeter-wave components.

[0114] (Variant of the first embodiment)

[0115] Figure 16 It is a cross-sectional schematic diagram showing a variant of the positional relationship between the first antenna 132 and the second antenna 232 indicating the first connection state. As Figure 16As shown, in a cross section perpendicular to the first front side 101, the first antenna 132 may be inclined relative to the first front side 101. In a cross section perpendicular to the first front side 101, the first antenna 132 may be inclined relative to the first inclined surface 187. The second antenna portion 234 of the second antenna 232 may be substantially parallel to the second back side 202. In the first connection state, the angle between the first antenna 132 and the second antenna 232 in a cross section perpendicular to both the first front side 101 and the second back side 202 is set to the first angle θ1. The first angle θ1 may be smaller than the sum of the third angle θ3 and the fourth angle θ4. The first angle θ1 is not particularly limited, and is, for example, greater than 2° and less than 18°.

[0116] Figure 17 2 is a cross-sectional schematic diagram showing a modified example of the positional relationship between the first antenna 132 and the second antenna 232 in the second connection state. Figure 17 As shown, in the second connection state, the angle between the first antenna 132 and the third antenna portion 236 of the second antenna 232 in the cross section perpendicular to both the first front surface 101 and the second back surface 202 is set to the second angle θ2. The second angle θ2 may be smaller than the sum of the third angle θ3 and the fourth angle θ4. The second angle θ2 is not particularly limited and may be smaller than the sum of the third angle θ3 and the fourth angle θ4. For example, the second angle θ2 may be half the sum of the third angle θ3 and the fourth angle θ4. In the present embodiment, the second angle θ2 is 10°. In addition, the second angle θ2 may be greater than 2° and less than 18°. According to such a structure, in the first connection state and the second connection state, the first antenna 132 and the second antenna 232 can be made nearly parallel. Therefore, for example, in a high frequency band with strong directivity, the signal can be received with better sensitivity.

[0117] The first angle θ1 may be substantially the same as or different from the second angle θ2. The absolute value of the difference between the first angle θ1 and the second angle θ2 is not particularly limited and may be 15° or less or 10° or less.

[0118] In the above description, the first antenna 132 is tilted relative to the first front surface 101 and the second antenna 232 is substantially parallel to the second back surface 202, but the electronic device 300 of the present disclosure is not limited thereto. Specifically, the first antenna 132 may be substantially parallel to the first front surface 101 and the second antenna 232 may be tilted relative to the second back surface 202, or the first antenna 132 may be tilted relative to the first front surface 101 and the second antenna 232 may be tilted relative to the second back surface 202.

[0119] (How to use electronic devices)

[0120] Next, the usage method of the electronic device 300 will be described. The electronic device 300 is, for example, a game console, a smart phone, a tablet computer, etc. The first device 100 and the second device 200 can be used in two cases: when they are connected to each other and when they are separated from each other. As Figure 6 and Figure 7 shown, the first device 100 and the second device 200 can be connected in a first connection state. As Figure 8 shown, in the first connection state, the second connection portion 220 faces the first direction A1 with respect to the first connection portion 120. As Figure 10 and Figure 11 shown, the first device 100 and the second device 200 can be connected in a second connection state. As Figure 13 shown, in the second connection state, the second connection portion 220 faces the second direction A2 with respect to the first connection portion 120. In the first connection state and the second connection state, the first wireless communication is performed by electromagnetic field coupling between the first antenna 132 and the second antenna 232.

[0121] In the first connection state and the second connection state, it is also possible to use the first antenna 132 and the second antenna 232 to send an image signal from the first device 100 to the second device 200. The image signal is, for example, an SLVS (Scalable Low Voltage Signaling) signal. For example, in the first device 100, an MIPI (Mobile Industry Processor Interface)-DSI (Display Serial Interface) signal is converted into an SLVS signal. The converted SLVS signal is sent from the first device 100 to the second device 200. In the second device 200, the SLVS signal is converted into an MIPI-DSI signal. As another method, it is also possible that the MIPI-DSI signal is not converted into an SLVS signal and is directly sent from the first device 100 to the second device 200.

[0122] It is also possible that, in the case where the first device 100 and the second device 200 are in a separated state, the first device 100 and the second device 200 can perform second wireless communication. The second wireless communication in the state where the first device 100 and the second device 200 are separated can also be performed by electromagnetic field coupling between antennas different from the first antenna 132 and the second antenna 232, respectively. Specifically, the second wireless communication can also be, for example, WiFi (registered trademark) communication. The frequency band of the signal used in the first wireless communication can also be higher than the frequency band of the signal used in the second wireless communication.

[0123] In addition, the second wireless communication is not limited to WiFi (registered trademark) communication. The second wireless communication can be, for example, communication using Bluetooth (registered trademark), or can be infrared communication. The second device 200 can receive a signal from the first device 100 and display an image, or can generate an image by itself without receiving a signal from the first device 100.

[0124] In the first connection state, the user can play a game in a single-screen mode using the first wireless communication. In the second connection state, the user can play a game in a dual-screen mode using the first wireless communication. In the case where the first device 100 and the second device 200 are separated, the first user uses the first device 100, and the second user uses the second device 200. The first user and the second user can play the same game simultaneously using the second wireless communication. In addition, as another usage method, in the state where the second device is placed, a single user can operate the first device 100 while referring to the screen of the second device 200.

[0125] Alternatively, at least one of the first device 100 and the second device 200 constituting the electronic device 300 may further include a storage unit (not shown) and / or a processor (not shown). The storage unit is, for example, DRAM (Dynamic Random Access Memory), a non-volatile memory. Application programs such as games can be stored in the storage unit. Alternatively, the processor can read the application program and execute information processing. The first display 110 and the second display 210 can also display, for example, an image generated as a result of information processing executed by the processor. The electronic device 300 can also be an information processing device other than a game console.

[0126] (Second Embodiment)

[0127] Next, the structure of the electronic device 300 according to the second embodiment will be described. The electronic device 300 according to the second embodiment is mainly different from the electronic device 300 according to the first embodiment in the structure of the first mechanical connection portion 180 and the structure of the second mechanical connection portion 280, and other structures are substantially the same as those of the electronic device 300 according to the first embodiment. Hereinafter, the description will focus on the structures different from those of the electronic device 300 according to the first embodiment.

[0128] Figure 18 FIG. is a partial perspective view showing the structure of the electronic device 300 according to the second embodiment. Figure 19 is along Figure 18 The sectional view taken along the XIX-XIX line of. As Figure 18 and Figure 19As shown, the first mechanical connection portion 180 includes a movable member 140, a fixed member 150, and a pair of third biasing portions 154. The movable member 140 includes a first plate member 141 and a pair of second plate members 142. In a plan view of the first front surface 101, the first plate member 141 has a trapezoidal shape. The pair of second plate members 142 are disposed on both sides of the first plate member 141.

[0135] In the above description, by pushing the unlocking button 191 in the third direction A3, the pair of second plate members 142 slide in the fourth direction A4 respectively, and the locking of each of the pair of movable hook parts 250 is released. The locking mechanism is shared in the first connection state and the second connection state. In addition, in the above description, the structure for unlocking by using the sliding mechanism is described, but the unlocking mechanism of the present disclosure is not limited to the sliding mechanism. Instead of the sliding mechanism, a link mechanism or a gear mechanism can be used.

The second haptic cue portion 82 may also be a portion that generates vibration when the user touches this portion. In this case, the first haptic cue portion 81 is a portion that does not generate vibration even when the user touches this portion.

[0169] Figure 24 It is a perspective schematic diagram showing the structure of the electronic device 300 according to the third embodiment indicating the first connection state. As Figure 24 shown, in the first connection state, it is arranged such that the second back surface 202 covers the first display 110. The first convex portion 10 is arranged to overlap with the second convex portion 20. Specifically, the front surface of the first convex portion 10 overlaps with the back surface of the second convex portion 20. The first connection portion 120 provided on the front surface of the first convex portion 10 and the second connection portion 220 provided on the back surface of the second convex portion 20 are connected in the first direction A1.

[0170] In the first connection state, in a direction perpendicular to the first front surface 101, the first input portion 1 and the third input portion 3 are arranged in parallel, and the second input portion 2 and the fourth input portion 4 are arranged in parallel. From another perspective, along the direction from the first front surface 101 toward the second back surface 202, the first input portion 1 and the third input portion 3 are arranged in parallel, and the second input portion 2 and the fourth input portion 4 are arranged in parallel.

[0171] In the first connection state, in a direction perpendicular to the first front surface 101, the fifth input portion 5 and the seventh input portion 7 are arranged in parallel, and the sixth input portion 6 and the eighth input portion 8 are arranged in parallel.

[0172] Figure 25 It is a perspective schematic diagram showing the structure of the electronic device 300 according to the third embodiment indicating the second connection state. In the second connection state, it is arranged such that the second back surface 202 does not cover the first display 110. The first convex portion 10 is arranged to overlap with the second convex portion 20. Specifically, the front surface of the first convex portion 10 overlaps with the back surface of the second convex portion 20. The first connection portion 120 provided on the front surface of the first convex portion 10 and the second connection portion 220 provided on the back surface of the second convex portion 20 are connected in the second direction A2.

[0173] In the second connection state, the first device 100 and the second device 200 are connected in such a way that the first convex portion 10 overlaps the second convex portion 20. Therefore, the first input portion 1, the second input portion 2, the fifth input portion 5, and the sixth input portion 6 are configured to be separated from the second device 200. Therefore, when the first input portion 1, the second input portion 2, the fifth input portion 5, and the sixth input portion 6 are each operated, the user's finger is not likely to interfere with the third input portion 3, the fourth input portion 4, the seventh input portion 7, the eighth input portion 8, and the second convex portion 20 of the second device 200. Thereby, the operability of the electronic device 300 is improved.

[0174] In addition, in the electronic device 300 according to the modified example of the third embodiment, the first input portion 1 to the eighth input portion 8 may be omitted. Specifically, the first device 100 may not separately include the first input portion 1, the second input portion 2, the fifth input portion 5, and the sixth input portion 6, and the second device 200 may not separately include the third input portion 3, the fourth input portion 4, the seventh input portion 7, and the eighth input portion 8.

[0175] A structure in which the second back surface 202 covers the first display 110 in the first connection state and the second back surface 202 covers the first display 110 in the second connection state is disclosed. However, it may be configured such that in the first connection state where the second connection portion 220 is connected to the first connection portion 120 in the first direction A1, the second back surface 202 covers the input portion 121, and in the second connection state where the second connection portion 220 is connected to the first connection portion 120 in the second direction A2, the second back surface 202 does not cover the input portion 121.

[0176] In addition, the first input portion 1 may be a structure extending to the first upper right surface portion 16. The third input portion 3 may be a structure extending to the second upper right surface portion 26. The fifth input portion 5 may be a structure extending to the first upper left surface portion 17. The seventh input portion 7 may be a structure extending to the second upper left surface portion 27.
