Description

electronic equipment

[0001] The present disclosure relates to electronic devices.

[0002] WO 2011 / 084298 (Patent Document 1) discloses a dual display mobile device.

[0003] International Publication No. 2011 / 084298

[0004] 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.

[0005] In an electronic device in which a first device and a second device are combined, there is room for improvement in the structure for switching between a plurality of connection states.

[0006] The electronic device according to the present disclosure includes a first device and a second device. The first device and the second device are detachable. The first device includes a first surface, a first display disposed on the first surface, and a first connection portion. The second device includes a second surface, a second display disposed on the second surface, a second back surface opposite the second surface, and a second connection portion disposed on the second back surface. The second connection portion is connectable to the first connection portion in a first direction and a second direction opposite to the first direction. In a first connection state in which the second connection portion is connected to the first connection portion in the first direction, the second back surface is disposed so as to cover the first display. In a second connection state in which the second connection portion is connected to the first connection portion in the second direction, the second back surface is disposed so as not to cover the first display. This provides a new connection state switching structure.

[0007] For example, when communication is performed between a first device and a second device, it is conceivable to provide an external terminal on each of the first device and the second device and connect them together, but if the first device and the second device each have an external terminal, there is a risk of unwanted high-frequency radiation being generated.

[0008] According to the electronic device described above, the first device may include a first substrate disposed within the first device and one or more first antennas provided on the first substrate. The second device may include a second substrate disposed within the second device and one or more second antennas provided on the second substrate. In each of the first and second connection states, the first and second antennas may be positioned to overlap when the first display is viewed in a plan view. The first and second devices may be capable of performing first wireless communication through electromagnetic coupling between the first and second antennas. This allows communication between the first and second devices in both the first and second connection states without the need for external terminals. This suppresses the generation of unnecessary high-frequency radiation. Furthermore, it reduces the need for measures against electrostatic discharge.

[0009] According to the electronic device described above, in each of the first connection state and the second connection state, the first antenna may be at least partially overlapped with the second antenna, thereby increasing the strength of electromagnetic field coupling.

[0010] According to the electronic device described above, one of the first antenna or the second antenna may have a first antenna unit. The other of the first antenna or the second antenna may have a second antenna unit and a third antenna unit. In the first connection state, the first antenna unit may be arranged to overlap with the second antenna unit. In the second connection state, the first antenna unit may be arranged to overlap with the third antenna unit. This allows the number of antenna units to be reduced to three. Compared to a case where two antenna units are arranged in the first device and two antenna units are arranged in the second device, the number of antenna units can be reduced.

[0011] According to the electronic device described above, the first antenna may have a first antenna portion. The second antenna may have a second antenna portion and a third antenna portion. When the first front surface is viewed in plan, the first antenna portion may be located adjacent to the first connection portion. When the second back surface is viewed in plan, the second connection portion may be located between the second antenna portion and the third antenna portion.

[0012] According to the electronic device described above, the first device may include a first substrate disposed within the first device and one or more first antennas provided on the first substrate. The second device may include a second substrate disposed within the second device and one or more second antennas provided on the second substrate. One of the first antenna or the second antenna may have a first antenna unit. The other of the first antenna or the second antenna may have a second antenna unit and a third antenna unit. In the first connected state, the second antenna unit may overlap with the first antenna unit, and the third antenna unit may be arranged so as not to overlap with the first antenna. In the second connected state, the third antenna unit may overlap with the first antenna unit, and the second antenna unit may be arranged so as not to overlap with the first antenna.

[0013] In the electronic device according to the above, when the first surface is viewed from above, the first antenna portion may be disposed adjacent to the first connection portion, and when the second back surface is viewed from above, the second connection portion may be disposed between the second antenna portion and the third antenna portion.

[0014] According to the electronic device described above, in the second connection state, the first device and the second device may be connected with the second display tilted relative to the first display.

[0015] According to the electronic device described above, in the first connection state, the first device and the second device may be connected in a state in which the second display is parallel to the first display.

[0016] In the electronic device according to the above, the first connection portion may have a first inclined surface inclined with respect to the first front surface, and the second connection portion may have a second inclined surface inclined with respect to the second rear surface.

[0017] According to the electronic device described above, in the first connection state, the angle between the first antenna and the second antenna in a cross section perpendicular to each of the first front surface and the second back surface is a first angle. In the second connection state, the angle between the first antenna and the second antenna in a cross section perpendicular to each of the first front surface and the second back surface is a second angle. The angle between the first front surface and the first inclined surface in a cross section perpendicular to the first surface is 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 a fourth angle. Each of the first angle and the second angle may be smaller than the sum of the third angle and the fourth angle. This makes it possible to maintain high electromagnetic coupling strength in both the first connection state and the second connection state.

[0018] According to the electronic device described above, when the first antenna and the second antenna are electromagnetically coupled, the first device and the second device may transmit and receive signals unidirectionally or bidirectionally. The first connection portion may include a first contact for supplying power. The second connection portion may include a second contact for supplying power. The first contact and the second contact may be connected in each of the first connection state and the second connection state. This allows power to be supplied using the first contact and the second contact. The power supply terminal is less susceptible to unwanted radiation, so it can be connected via a wire.

[0019] According to the electronic device described above, when the first device and the second device are separated, the first device and the second device may be able to perform a second wireless communication, thereby enabling communication between the first device and the second device even when the first device and the second device are separated.

[0020] According to the electronic device described above, the first wireless communication in the first connection state and the second connection state may be performed by electromagnetic coupling between the first antenna and the second antenna. The second wireless communication in a state in which the first device and the second device are separated may be performed by electromagnetic coupling between antennas different from the first antenna and the second antenna. The frequency band of the signal used in the first wireless communication may be higher than the frequency band of the signal used in the second wireless communication. Generally, higher frequencies require higher directivity. By setting 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.

[0021] According to the electronic device described above, the first connection portion may have a first receiving groove and a second receiving groove opposite the first receiving groove. The second connection portion may have a movable hook and a fixed hook opposite the movable hook. In the first connection state, the movable hook may not be positioned in the first receiving groove, and the fixed hook may be positioned in the second receiving groove. In the second connection state, the movable hook may be positioned in the second receiving groove, and the fixed hook may be positioned in the first receiving groove. This allows the second device to be easily detached from the first device in the first connection state. On the other hand, in the second connection state, the second device can be firmly fixed to the first device.

[0022] According to the above electronic device, the first connection portion may have a first electrical connection portion and a first mechanical connection portion. The first electrical connection portion may be provided above or below the first display. The first mechanical connection portion may be provided so as to sandwich the first electrical connection portion in the longitudinal direction of the first display. The second connection portion may have a second electrical connection portion and a second mechanical connection portion. The second electrical connection portion may be provided above or below the second display. The second mechanical connection portion may be provided so as to sandwich the second electrical connection portion in the longitudinal direction of the second display. The first electrical connection portion may be electrically connected to the second electrical connection portion. The first mechanical connection portion may be mechanically connected to the second mechanical connection portion.

[0023] When the mechanical connection parts are arranged so as to sandwich the electrical connection parts from the short side of the display, additional space is required in the short side. On the other hand, there is excess space on both sides of the electrical connection parts in the long side of the display. By arranging the mechanical connection parts so as to sandwich the electrical connection parts from the long side of the display, the space can be used effectively.

[0024] In the electronic device according to the above, the terminals of the first electrical connection portion may be arranged in the longitudinal direction of the first display. The terminals of the second electrical connection portion may be arranged in the longitudinal direction of the second display. When the terminals of the electrical connection portion are arranged in the longitudinal direction of the display, the length of the display in the transverse direction can be increased compared to when the terminals of the electrical connection portion are arranged in the transverse direction of the display. As a result, the area of ​​the display can be increased.

[0025] According to the electronic device described above, the first device may include an input unit capable of stick or button operation. The second display may include a touch panel capable of touch input. Because the first device includes an input unit capable of stick or button operation, it is possible to perform operations appropriate for the application. Furthermore, in the first connected state, the input unit capable of stick or button operation is covered by the second device. Therefore, the input unit is less likely to get caught on other objects when carrying the electronic device.

[0026] According to the electronic device described above, the first device may include a first housing surrounding the first display and including a first protrusion extending outward from the first display. The second device may include a second housing surrounding the second display and including a second protrusion extending outward from the second display. The first connection portion may be provided on the front side of the first protrusion. The second connection portion may be provided on the back side of the second protrusion. This allows the first device and the second device to be connected while increasing the sizes of the first display and the second display.

[0027] According to the electronic device described above, the first device may include a first back surface, a first top surface, a first bottom surface, a first right side surface, and a first left side surface. The first back surface may be located opposite the first front surface. The first top surface may be connected to the first front surface and the first back surface. The first bottom surface may be located opposite the first front surface. The first right side surface may be connected to each of the first front surface, the first back surface, the first top surface, and the first bottom surface. The first left side surface may be located opposite the first right side surface. The second device may include a second top surface, a second bottom surface, a second right side surface, and a second left side surface. The second top surface may be connected to the second front surface and the second back surface. The second bottom surface may be located opposite the second top surface. The second right side surface may be connected to each of the second front surface, the second back surface, the second top surface, and the second bottom surface. The second left side surface may be located opposite the second right side surface. The first convex portion may be provided on the first upper surface. The second convex portion may be provided on the second upper surface. The first device may include a first input unit provided on a portion of the first right side surface of the first convex portion, and a second input unit provided on a portion of the first upper surface other than the first convex portion. The second device may include a third input unit provided on a portion of the second right side surface of the second convex portion, and a fourth input unit provided on a portion of the second upper surface other than the second convex portion.

[0028] This makes it less likely that the first input unit will be mistakenly pressed instead of the second input unit. Similarly, it makes it less likely that the third input unit will be mistakenly pressed instead of the fourth input unit. Furthermore, in the second connected state, the fourth input unit of the second device is located at a position away from the first device. Therefore, it is less likely to get in the way when operating the first input unit. In a state in which the first and second devices are separated, the input units are provided at a common position, allowing the first and second devices to be operated with the same feel. Furthermore, two different inputs can be performed by sliding a finger horizontally.

[0029] In the electronic device according to the above, in the first connected state, the first input unit and the third input unit may be arranged side by side in a direction perpendicular to the first surface, and the second input unit and the fourth input unit may be arranged side by side, which makes it easier for the user to remember the positions of the input units.

[0030] In the electronic device described above, an input unit or a camera lens may be provided on the surface of the second protrusion. This allows for a functional component that can be used in both the first and second connection states. Therefore, while using the second protrusion as a connection unit, the area of ​​the second device other than the second protrusion can be effectively utilized. For example, the second display can be enlarged.

[0031] According to the electronic device described above, the second display may include a touch panel that can be touched and a touch panel cover that covers the touch panel and allows input operations to be performed on the touch panel. The second display may include a first tactile sense presentation unit configured by the touch panel cover, and a second tactile sense presentation unit in which an opening is provided in the touch panel cover and the touch panel is exposed through the opening. This allows the user to easily grasp the position of the second tactile sense presentation unit when the second display has a touch panel.

[0032] According to the present disclosure, an electrical device having a new switching structure can be provided.

In the first connection state, the second back surface 202 is arranged to cover the first display 110. The second back surface 202 may be arranged to cover the entire surface of the first display 110, or may be arranged to cover at least a portion of the surface. The second back surface 202 is arranged to overlap the first surface 101. The second surface 201 faces outward. The user can view the second display 210 arranged on the second surface 201. In the first connection state, the Hall element 130 is arranged to overlap the magnet portion 230. The Hall element 130 may determine that the current connection state is the first connection state.

[0059] The direction from first left side surface 106 to first right side surface 105 of first device 100 corresponds to reference direction B. In the first connection state, when first display 110 is viewed in a plan view, the direction from second left side surface 206 to second right side surface 205 of second device 200 is first direction A1. In the first connection state, first device 100 and second device 200 are connected such that, when first display 110 is viewed in a plan view, the direction from second left side surface 206 to second right side surface 205 of second device 200 is the same as reference direction B.

[0060] 7 is a schematic cross-sectional view taken along line VII-VII in FIG. 6. 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 each provided on the back side of the first main body portion 183. The second receiving groove 182 is located on the opposite side of 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.

[0061] The first connection portion 120 is provided with a fourth opening 186. The unlock button 191 is exposed from the fourth opening 186. The first device 100 has a first rotation shaft 192. The unlock button 191 is capable of swinging around the first rotation shaft 192 as the center of rotation. The fixed hook 281 is disposed in a second receiving groove 182 provided on the back side of the first main body portion 183. The unlock button 191 may be in contact with the fixed hook 281.

[0062] The second device 200 has a second rotation shaft 273 and a biasing member 274. The movable hook 270 can swing around the second rotation shaft 273. 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 attached to the second rotation shaft 273 so as to be able to swing. 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 each disposed inside the second device 200. A portion of the movable hook 270 passes through the third opening 284.

[0063] As shown in FIGS. 3 and 5 , the width (second width W2) of the movable hook 270 is greater than the width (first width W1) of the pair of first protrusions 184. Therefore, in the first connected state, the movable hook 270 rides on the pair of first protrusions 184. In other words, the movable hook 270 is not positioned in the first receiving groove 181. As shown in FIG. 7 , in the first connected state, the fixed hook 281 enters the second receiving groove 182, thereby connecting the first device 100 and the second device 200. This attaches the second device 200 to the first device 100. To detach the second device 200 from the first device 100, rotate the second device 200 in the first rotation direction R1. In this case, there is no need to press the unlock button 191.

[0064] As shown in FIG. 7 , electronic device 300 has fourth protrusion 9. Fourth protrusion 9 may be attached to first surface 101 of first device 100 or to second back surface 202 of second device 200. In the first connected state, fourth protrusion 9 is located between first surface 101 and second back surface 202. In the first connected state, first surface 101 and second back surface 202 are substantially parallel. In the first connected state, first device 100 and second device 200 may be connected with second display 210 parallel to first display 110. The fourth protrusion 9 forms a gap between first surface 101 and second back surface 202. Ninth input unit 121 is spaced apart from second back surface 202. Fourth protrusion 9 can prevent rattling between first device 100 and second device 200 in the first connected state.

[0065] As shown in Fig. 7, the first electrical connection portion 160 is electrically connected to the second electrical connection portion 260. Fig. 8 is a schematic diagram showing the relationship between the first connection portion and the second connection portion in a first connection state. The first connection state is a state in which the second connection portion 220 is connected to the first connection portion 120 in the first direction A1. In the first connection state, the first contact point 162 is electrically connected to the second contact point 262.

[0066] 8 , 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 portion 160 may be arranged in the longitudinal direction of the first display 110. The first terminal 162a is located closest to the first left side surface. The third terminal 162c is located closest to the first right side surface. The second terminal 162b is located midway between the first terminal 162a and the third terminal 162c. The direction from the first terminal 162a toward the third terminal 162c corresponds to reference direction B.

[0067] 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 unit 260 may be arranged in the longitudinal direction of the second display 210. The fourth terminal 262a is located closest to the second left side surface. The sixth terminal 262c is located closest to the second right side surface. The fifth terminal 262b is located midway 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 unit 220 is positioned relative to the first connection unit 120 so that the direction from the fourth terminal 262a toward the sixth terminal 262c is the same as the first direction A1. The terminal arrangement is not limited to this, and the first contact 162 and the second contact 262 may be arranged in such a manner that they are connected to each other in the first connection state and the second connection state. For example, the multiple terminals may be arranged so that the other terminals are line-symmetrical with respect to a terminal arranged in the center.

[0068] 9 is a schematic cross-sectional view taken along line IX-IX in FIG. 6. As shown in FIG. 9, the first magnetic connection portion 111 is disposed 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 surface 101 of the first housing 165. The inclination angle of the first inclined surface 187 with respect to the first surface 101 is, for example, 10°. The first magnetic connection portion 111 is disposed along the first inclined surface 187. The surface of the first magnetic connection portion 111 may be substantially parallel to the first inclined surface 187.

[0069] Similarly, the second magnetic connection portion 211 is disposed 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 rear surface 202 of the second housing 265. The inclination angle of the second inclined surface 287 with respect to the second rear surface 202 is, for example, 10°. The second magnetic connection portion 211 is disposed along the second inclined surface 287. The surface of the second magnetic connection portion 211 may be substantially parallel to the second inclined surface 287. The surface of the second magnetic connection portion 211 may be substantially parallel to the surface of the first magnetic connection portion 111.

[0070] 10 is a front view schematic diagram showing the configuration of electronic device 300 in the second connection state. In the second connection state, second back surface 202 is positioned so as not to cover first display 110. Therefore, the user can view both first display 110 and second display 210. In the second connection state, first front surface 101 of first device 100 is positioned so as to overlap with a portion of first back surface 102 of second device 200. In the second connection state, Hall element 130 is positioned so as not to overlap magnet portion 230. The Hall element 130 may determine that the current connection state is the second connection state.

[0071] In the second connection state, when first display 110 is viewed in a plan view, the direction from second left side surface 206 to second right side surface 205 of second device 200 is second direction A2. In the second connection state, first device 100 and second device 200 are connected such that, when first display 110 is viewed in a plan view, the direction from second left side surface 206 to second right side surface 205 of second device 200 is opposite to reference direction B.

[0072] Figure 11 is a schematic cross-sectional view taken along line XI-XI in Figure 10. As shown in Figure 11, in the second connected state, the movable hook 270 is disposed in the second receiving groove 182, and the fixed hook 281 is disposed in the first receiving groove 181. The movable hook 270 is fitted into the second receiving groove 182. The fixed hook 281 is fitted into the first receiving groove 181. As a result, the first mechanical connection part 180 is mechanically fixed to the second mechanical connection part 280.

[0073] 11 , first electrical connection portion 160 is electrically connected to second electrical connection portion 260. Specifically, in the second connected state, first contact 162 and second contact 262 are connected. Second rear surface 202 is inclined with respect to first surface 101. In the second connected state, first device 100 and second device 200 may be connected with second display 210 inclined with respect to first display 110. The inclination angle of second rear surface 202 with respect to first surface 101 is, for example, 20°.

[0074] 12 is a cross-sectional view showing the state in which the electronic device 300 is unlocked in the second connected state. As shown in FIG. 12 , the unlock button 191 is pushed into the first device 100 along the third direction A3. The unlock button 191 presses the movable hook 270, causing the movable hook 270 to be pushed out of the second receiving groove 182. As a result, the mechanical lock is released. In this state, when the second device 200 is rotated in the second rotation direction R2, the second device 200 is separated from the first device 100.

[0075] 13 is a schematic diagram showing the relationship between the first and second connection portions in the second connection state. In the second connection state, the second connection portion 220 is connected to the first connection 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 connection portion 220 is positioned relative to the first connection portion 120 so that the direction from the fourth terminal 262a toward the sixth terminal 262c is the same as the second direction A2.

[0076] Each of the second terminal 162b and the fifth terminal 262b is, for example, a terminal for supplying power. In each of the first and second connection states, the second terminal 162b is electrically connected to the fifth terminal 262b. The purpose of the first terminal 162a may be the same as the purpose of the third terminal 162c. Similarly, the purpose of the fourth terminal 262a may be the same as the purpose of the sixth terminal 262c. In this case, the same function can be realized in each of the first and second connection states. Furthermore, in the first and second connection states, the first contact 162 and the second contact 262 may define corresponding multiple electrical communication paths. The purposes of the first terminal 162a, the third terminal 162c, the fourth terminal 262a, and the sixth terminal 262c are not particularly limited, and may be, for example, a ground terminal, a terminal for determining whether the first device 100 and the second device 200 are connected, or a terminal for resetting the display.

[0077] Fig. 14 is a cross-sectional schematic diagram showing the positional relationship between the first antenna 132 and the second antenna 232 in the first connection state. As shown in Fig. 14, in the first connection state, the first antenna 132 is arranged so as to overlap with the second antenna portion 234 of the second antenna 232. In other words, in the first connection state, when the first display 110 is viewed from above, the first antenna 132 and the second antenna 232 are arranged in overlapping positions. Each of the first antenna 132 and the second antenna 232 is a plate-shaped module.

[0078] 14 , in a cross section perpendicular to the first surface 101, the first antenna 132 is substantially parallel to the first surface 101. The first antenna 132 is inclined with respect to the first inclined plane 187. In a cross section perpendicular to the second back surface 202, the second antenna portion 234 of the second antenna 232 is substantially parallel to the second back surface 202. The second antenna portion 234 of the second antenna 232 is inclined with respect to the second inclined plane 287. In the first connected state, the second antenna portion 234 of the second antenna 232 is substantially parallel to the first antenna 132.

[0079] In the first connected state, the second inclined surface 287 is in contact with the first inclined surface 187. The angle between the first surface 101 and the first inclined surface 187 in a cross section perpendicular to the first surface 101 is defined as a third angle θ3. The third angle θ3 is, for example, 10°. The angle between the second back surface 202 and the second inclined surface 287 in a cross section perpendicular to the second back surface 202 is defined as a fourth angle θ4. The fourth angle θ4 is, for example, 10°.

[0080] 15 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 shown in Fig. 15, in the second connection state, the first antenna portion 132 of the first antenna 132 is arranged to overlap with the third antenna portion 236 of the second antenna 232. In other words, in the second connection state, when the first display 110 is viewed from above, the first antenna 132 and the second antenna 232 are arranged in overlapping positions. As described above, in each of the first connection state and the second connection state, at least a portion of the first antenna 132 is arranged in a position that overlaps with the second antenna 232.

[0081] 15 , 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 each of the first front surface 101 and the second back 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.

[0082] 14 and 15 have been described in which the first inclined surface 187 and the second inclined surface 287 are provided, the first mechanical connection portion 180 may not be provided with the first inclined surface 187, and the second mechanical connection portion 280 may not be provided with the second inclined surface 287. Specifically, the first mechanical connection portion 180 and the second mechanical connection portion 280 may be configured to be connected 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 or the second device 200 may be inclined with respect to the other of the first device 100 or the second device 200.

[0083] Although the above describes a configuration in which the first antenna 132 has one antenna unit and the second antenna 232 has two antenna units, the present disclosure is not limited to this configuration. In an electronic device 300 according to another aspect, the first antenna 132 may have two antenna units and the second antenna 232 may have one antenna unit. Specifically, the second antenna 232 may have a first antenna unit. The first antenna 132 may have a second antenna unit and a third antenna unit. In the first connected state, the first antenna unit may be arranged to overlap the second antenna unit. In the second connected state, the first antenna unit may be arranged to overlap the third antenna unit. In an electronic device 300 according to yet another aspect, the first antenna 132 may have two antenna units and the second antenna 232 may have two antenna units.

[0084] In each of the first connection state and the second connection state, first device 100 and second device 200 can perform first wireless communication by electromagnetically coupling first antenna 132 and second antenna 232. When first antenna 132 and second antenna 232 are electromagnetically coupled, first device 100 and second device 200 may transmit and receive signals bidirectionally. Second device 200 may unilaterally receive a signal transmitted by first device 100. First device 100 may unilaterally receive a signal transmitted by second device 200. Each of first antenna 132 and second antenna 232 is, but is not limited to, a 60 GHz millimeter-wave module, for example.

[0085] (Modification of the first embodiment)

[0086] FIG. 16 is a cross-sectional schematic diagram illustrating a modified example of the positional relationship between the first antenna 132 and the second antenna 232 in the first connection state. As shown in FIG. 16 , in a cross section perpendicular to the first surface 101, the first antenna 132 may be inclined with respect to the first surface 101. In a cross section perpendicular to the first surface 101, the first antenna 132 may be inclined with respect to the first inclined plane 187. The second antenna portion 234 of the second antenna 232 may be substantially parallel to the second back surface 202. In the first connection state, the angle between the first antenna 132 and the second antenna 232 in a cross section perpendicular to each of the first surface 101 and the second back surface 202 is defined as a 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, but is, for example, 2° or greater and 18° or less.

[0087] FIG. 17 is a cross-sectional schematic diagram illustrating a modified example of the positional relationship between the first antenna 132 and the second antenna 232 in the second connection state. As shown in FIG. 17 , in the second connection state, the angle between the first antenna 132 and the third antenna portion 236 of the second antenna 232 in a cross section perpendicular to each of the first front surface 101 and the second back surface 202 is defined as a 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, but 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 this embodiment, the second angle θ2 is 10°. The second angle θ2 may be greater than or equal to 2° and less than or equal to 18°. This configuration allows the first antenna 132 and the second antenna 232 to be closer to parallel in both the first connection state and the second connection state. Therefore, for example, signals can be received with good sensitivity in a high frequency band with strong directionality.

[0088] 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, but may be 15° or less, or 10° or less.

[0089] Although the above describes a case where first antenna 132 is inclined with respect to first surface 101 and second antenna 232 is substantially parallel to second rear surface 202, electronic device 300 of the present disclosure is not limited to this. Specifically, first antenna 132 may be substantially parallel to first surface 101 and second antenna 232 may be inclined with respect to second rear surface 202, or first antenna 132 may be inclined with respect to first surface 101 and second antenna 232 may be inclined with respect to second rear surface 202.

[0090] (How to use electronic devices)

[0091] Next, a method of using the electronic device 300 will be described. The electronic device 300 may be, for example, a game console, a smartphone, a tablet PC, or the like. The first device 100 and the second device 200 can be used both when connected to each other and when separated from each other. As shown in FIGS. 6 and 7 , in a first connection state, the first device 100 and the second device 200 are connectable. As shown in FIG. 8 , in the first connection state, the second connection unit 220 faces the first direction A1 relative to the first connection unit 120. As shown in FIGS. 10 and 11 , in a second connection state, the first device 100 and the second device 200 are connectable. As shown in FIG. 13 , in the second connection state, the second connection unit 220 faces the second direction A2 relative to the first connection unit 120. In the first and second connection states, the first wireless communication is performed by electromagnetic coupling between the first antenna 132 and the second antenna 232.

[0092] In the first connection state and the second connection state, an image signal may be transmitted from first device 100 to second device 200 using first antenna 132 and second antenna 232. The image signal may be, for example, a scalable low voltage signaling (SLVS) signal. For example, in first device 100, a Mobile Industry Processor Interface (MIPI)-Display Serial Interface (DSI) signal is converted into an SLVS signal. The converted SLVS signal is sent from first device 100 to second device 200. In second device 200, the SLVS signal is converted into an MIPI-DSI signal. As another aspect, the MIPI-DSI signal may be transmitted directly from first device 100 to second device 200 without being converted into an SLVS signal.

[0093] When first device 100 and second device 200 are separated, first device 100 and second device 200 may be able to perform second wireless communication. The second wireless communication when first device 100 and second device 200 are separated may be performed by electromagnetic field coupling between antennas different from first antenna 132 and second antenna 232. Specifically, the second wireless communication may be, for example, Wi-Fi (registered trademark) communication. The frequency band of the signal used in the first wireless communication may be higher than the frequency band of the signal used in the second wireless communication.

[0094] The second wireless communication is not limited to Wi-Fi (registered trademark) communication. The second wireless communication may be, for example, Bluetooth (registered trademark) communication or infrared communication. Second device 200 may receive a signal from first device 100 and display an image, or may generate an image by itself without receiving a signal from first device 100.

[0095] In the first connection state, a user can play a game in single-screen mode using the first wireless communication. In the second connection state, a user can play a game in dual-screen mode using the first wireless communication. When the first device 100 and the second device 200 are separated, a first user uses the first device 100 and a 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. As another usage method, one user can operate the first device 100 while viewing the screen of the second device 200 while the second device is placed down.

[0096] At least one of first device 100 and second device 200 constituting electronic device 300 may further include a storage unit (not shown) and / or a processor (not shown). The storage unit may be, for example, a dynamic random access memory (DRAM) or a non-volatile memory. The storage unit may store an application program, for example, a game. The processor may be capable of loading the application program and executing information processing. First display 110 and second display 210 may display, for example, an image generated as a result of information processing executed by the processor. Electronic device 300 may be an information processing device other than a game console.

[0097] Second Embodiment

[0098] Next, the configuration of the electronic device 300 according to the second embodiment will be described. The electronic device 300 according to the second embodiment differs from the electronic device 300 according to the first embodiment mainly in the configurations of the first mechanical connection unit 180 and the second mechanical connection unit 280, but other configurations are substantially the same as those of the electronic device 300 according to the first embodiment. The following description will focus on the configurations that differ from the electronic device 300 according to the first embodiment.

[0099] FIG. 18 is a partial perspective schematic diagram showing the configuration of an electronic device 300 according to a second embodiment. FIG. 19 is a cross-sectional schematic diagram taken along line XIX-XIX in FIG. 18. As shown in FIGS. 18 and 19, the first mechanical connection unit 180 includes a movable member 140, a fixed member 150, and a pair of third biasing members 154. The movable member 140 includes a first plate member 141 and a pair of second plate members 142. When the first surface 101 is viewed from above, 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. Each of the pair of third biasing members 154 biases each of the pair of second plate members 142 in a direction toward the first plate member 141.

[0100] The fixing member 150 has an upper surface plate 151 and a partition plate 152. The upper surface plate 151 is disposed above the first magnetic connection portion 111. The partition plate 152 is attached to the upper surface plate 151. The partition plate 152 extends from the upper surface plate 151 toward the first rear surface 102. The first magnetic connection portion 111 is disposed between the pair of partition plates 152.

[0101] The second mechanical connection part 280 has a pair of movable hook parts 250, a pair of rotation shaft parts 253, a pair of fourth biasing parts 254, and a bottom plate 255. Each of the pair of movable hook parts 250 can swing around each of the pair of rotation shaft parts 253. Each of the pair of movable hook parts 250 has a second claw part 251 and a second support part 252. The second claw part 251 is connected to the second support part 252. The second support part 252 is attached to the rotation shaft part 253 so as to be able to swing. Each of the pair of fourth biasing parts 254 biases each of the pair of movable hook parts 250. The bottom plate 255 is disposed below the second magnetic connection part 211.

[0102] 19 , when the unlock button 191 is pressed into the first device 100 along the third direction A3, the first plate member 141 pushes each of the pair of second plate members 142 outward. Each of the pair of second plate members 142 moves in a fourth direction A4 perpendicular to the third direction A3. As a result, each of the pair of second plate members 142 pushes the second claw portion 251 of each of the pair of movable hook portions 250 outward. As a result, each of the pair of movable hook portions 250 is unlocked. The pair of movable hook portions 250 in the unlocked state is shown by dashed lines.

[0103] When the user releases the lock release button 191, the third biasing portion 154 moves each of the pair of second plate members 142 to their original positions. The fourth biasing portion 254 moves each of the pair of movable hook portions 250 to their original positions. The second claw portion 251 of each of the pair of movable hook portions 250 moves to the underside of the upper plate 151. As a result, the second mechanical connection portion 280 is fixed to the first mechanical connection portion 180. The pair of movable hook portions 250 in the locked state are shown by solid lines.

[0140] Fig. 24 is a schematic perspective view showing the configuration of the electronic device 300 according to the third embodiment in the first connected state. As shown in Fig. 24 , in the first connected state, the second rear surface 202 is arranged to cover the first display 110. The first protrusion 10 is arranged to overlap the second protrusion 20. Specifically, the front surface of the first protrusion 10 overlaps the rear surface of the second protrusion 20. The first connection portion 120 provided on the front surface of the first protrusion 10 is connected to the second connection portion 220 provided on the rear surface of the second protrusion 20 in the first direction A1.

[0141] In the first connected state, the first input unit 1 and the third input unit 3 are arranged side by side, and the second input unit 2 and the fourth input unit 4 are arranged side by side in a direction perpendicular to the first surface 101. From another perspective, the first input unit 1 and the third input unit 3 are arranged side by side, and the second input unit 2 and the fourth input unit 4 are arranged side by side in a direction from the first surface 101 toward the second back surface 202.
