Description

  The present invention relates to an information processing apparatus and an information processing system.

  In recent years, tablet-type terminal devices have rapidly spread due to their low price, small size, and high speed. Tablet-type terminal devices can be easily carried, can access the Internet, etc. regardless of time and place, and are used in various forms such as acquisition of information and communication with others.

  And since the tablet-type terminal device is easy to carry and its weight, it is often handled randomly. For example, it is conceivable that the tablet-type terminal device is handled by being swung around with one hand, or throwing the bag together while being put in the bag. In addition, tablet-type terminal devices may be used as a substitute for notebooks and textbooks during classes at educational sites, but in that case, vibrations and shocks may be caused by dropping from a small desk or carrying around at school. It is possible to receive. Therefore, the tablet terminal device and accessories are required to be robust.

  For example, there are a slim keyboard for enabling keyboard input and a keyboard docking station for extending other functions in addition to the keyboard as accessories of the tablet-type terminal device. Hereinafter, the function expansion unit including the keyboard is referred to as a keyboard dock. The keyboard dock can be folded up like a notebook PC (Personal Computer) while connected to the tablet terminal, and the user can carry the tablet terminal with the keyboard dock connected.

  As a method of fixing the connection between the tablet terminal device and the function expansion unit such as the keyboard dock, there are a method of fixing by hooking a hook-shaped fastener to a connection partner and a method of fixing by magnetic force using a magnet. . In the former, for example, the function expansion unit has a sliding hook-shaped fastener. Then, the tablet terminal device is installed so that the fastener of the function expansion unit fits into a fastener receiver that is a hooking hole provided in the tablet terminal device. At this time, the fastener is slid to be caught by the fastener receiver, and the tablet terminal device is fixed to the function expansion unit. In the latter, magnets are provided in both the tablet terminal device and the function expansion unit. And a tablet type terminal device is fixed to a function expansion unit because each magnet attracts.

  Here, in the fixing using the hook-shaped fastener, the tablet-type terminal device is firmly fixed so that it does not come off even if the tablet-type terminal device is pulled out from the function expansion unit. However, since it is firmly fixed in this way, there is a possibility that all the stress due to the impact such as dropping may be applied to the fastener and the fastener receiver. Therefore, it is preferable that the fastener and the fastener receiver have a strength that can withstand the stress.

  Conventionally, in order to avoid breakage between the fastener and the fastener receiver, a technique has been proposed in which the resin of the fastener receiving portion is made into a double structure to increase the strength. Further, there is a conventional technique in which a metal main body and a plastic antenna cover are integrally formed by an insert molding method, and an engaging means is formed at a joint portion between the metal main body and the plastic antenna cover.

JP 2009-266195 A

  However, when the resin of the fastener receiving part has a double structure, the timing of sliding of the sliding hook that is the fastener of the function expansion unit becomes a problem. The function expansion unit is provided with an unlock button at the insertion position of the tablet terminal device. When the tablet terminal device is fitted into the keyboard dock, the lock release button is pressed by the tablet terminal device. When the lock release button is pressed, the slide lock mechanism that prevents the fastener from sliding is released, and the fastener slides. At this time, if the lower jaw of the hook-shaped fastener is completely inside the fastener receiver, it is fixed without any problem. On the other hand, it is conceivable that the outer cover that pushes the button is moved away from the fastener receiver due to the variation of the fitting state in the assembly or the deformation after the assembly by using the double structure. In this case, the hook slides before the jaw under the hook-shaped retainer enters the interior of the retainer receiver, and it is fixed without contacting with the opening of the retainer receiver or the like. There is a risk of disappearing.

  In addition, the relationship between the clip position of the clip and the position of the opening of the clip receiver can be obtained by using the conventional technique in which insert molding is performed while forming the engagement means at the joint between the metal body and the plastic antenna cover. There is a possibility that a state that cannot be fixed occurs.

  The disclosed technology has been made in view of the above, and an object thereof is to provide an information processing apparatus and an information processing system that securely fix a connection having strength with a function expansion unit.

  An information processing apparatus and an information processing system disclosed in the present application have, in one aspect, a housing having an internal space. The internal member is partly exposed to the outside of the housing and disposed in the internal space, and is provided on the pressing surface that is included in the exposed portion and protrudes a predetermined amount toward the outside and the external device An opening that engages the hook, and when connecting to the external device, the attachment hook is operated in a state in which the attachment hook is inserted into the opening to engage the opening. The operation button is pressed on the pressing surface.

  According to one aspect of the information processing apparatus and the information processing system disclosed in the present application, there is an effect that a connection having strength with the function expansion unit can be reliably fixed.

  Example 1 will be described. FIG. 1 is a perspective view of a tablet terminal device. FIG. 2 is an exploded perspective view of the tablet terminal device.

  The tablet terminal device 100 includes a touch panel 11, a front cover 12, and a rear cover 13. The touch panel 11 is disposed on the front cover 12. Further, the front cover 12 and the rear cover 13 on which the touch panel 11 is mounted are combined and fitted to form one plate-like casing having a space inside.

  Hereinafter, a direction from the rear cover 13 toward the touch panel 11 is referred to as a Z direction, and a direction from the touch panel 11 toward the rear cover 13 is referred to as a reverse Z direction. Further, the direction of the arrow in the figure in the short direction of the tablet terminal device 100 is referred to as Y direction, and the opposite direction is referred to as reverse Y direction. Also, the direction of the arrow in the figure in the longitudinal direction of the tablet terminal device 100 is referred to as the X direction, and the opposite direction is referred to as the reverse X direction.

  As illustrated in FIG. 2, the tablet terminal device 100 is assembled by stacking a rear cover 13, a core cover 14, a front cover 12, and a touch panel 11 in the Z direction.

  The touch panel 11 has a liquid crystal display, for example. The touch panel 11 displays an image on the display. The touch panel 11 receives an input of a pressed position on the screen when the display is pressed.

  The front cover 12 has a frame for fitting the touch panel 11. The front cover 12 includes a cover around the touch panel 11 of the tablet terminal device 100 and a side cover. Then, the front cover 12 on which the touch panel 11 is mounted is combined with the core cover 14 to cover the internal components assembled to the core cover 14.

  The core cover 14 is a member for assembling internal components. The core cover 14 is covered with the front cover 12 and the rear cover 13 with the internal components attached. Here, the internal components are a group of components that realize various functions of the tablet terminal device 100 including a main board on which a CPU (Central Processing Unit) is mounted. Other internal components include a hard disk, a communication device, a speaker, a connection cable, and the like. For example, a main board on which a CPU is mounted is attached to the core cover 14.

  The outside of the core cover 14 is covered with the front cover 12 and the rear cover 13. That is, the core cover 14 is disposed in an internal space formed by combining the front cover 12 and the rear cover 13. The core cover 14 corresponds to an example of “internal member”.

  The rear cover 13 covers the surface of the core cover 14 on the side opposite to the front cover 12. The rear cover 13 is fitted to the front cover 12 with the core cover 14 interposed therebetween, and is coupled to the rear cover 13 by a fastener such as a screw. A battery or the like may be disposed between the rear cover 13 and the core cover 14. The tablet terminal device 100 has a plate-shaped housing formed by combining and fitting the front cover 12 and the rear cover 13.

  Returning to FIG. 1, the description will be continued. The tablet terminal device 100 has mounting openings 101 and 102, a connector 103, and positioning pin insertion holes 104 and 105 on the side surface of the end portion in the reverse Y direction of the casing formed by the front cover 12 and the rear cover 13. Have FIG. 3 is an enlarged view of the vicinity of the mounting opening. As shown in FIGS. 1 and 3, the mounting openings 101 and 102 are arranged on both sides of the connector 103.

  The attachment openings 101 and 102 are holes for engaging the attachment hooks 201 and 202 of the keyboard dock 200 described later to fix the connection. 4 is a cross-sectional view taken along line AA in FIG. FIG. 5 is an enlarged cross-sectional view of the vicinity of the opening in FIG. Since the mounting opening 101 and the mounting opening 102 have substantially the same structure, here, the mounting opening 101 will be described as an example.

  The mounting opening 101 is formed by the front cover 12 and the core cover 14. A front cover 12 and a core cover 14 are formed in two layers on the X-direction side wall forming the mounting opening 101. That is, the wall on the X direction side that forms the mounting opening 101 is formed by the front cover 12 on the outside and the core cover 14 on the inside. The wall on the reverse X direction side that forms the mounting opening 101 is formed by the core cover 14.

  The wall of the core cover 14 on the X direction side of the mounting opening 101 has a button pressing surface 141 facing in the reverse Y direction, that is, outward. Further, the wall of the core cover 14 on the opposite X direction side of the mounting opening 101 has a hook hooking surface 142 directed in the Y direction, that is, inward. That is, part of the core cover 14 including the hook hooking surface 142 is exposed to the outside from the housing formed by the front cover 12 and the rear cover 13.

  The attachment hooks 201 and 202 are inserted into the attachment openings 101 and 102 and engaged by sliding, and the connection between the tablet terminal device 100 and the keyboard dock 200 is fixed. Here, the state in which the mounting opening 101 and the mounting hook 201 are engaged refers to a state in which the lower jaw of the mounting hook 201 is in contact with the hook hooking surface 142. Further, the lower jaw of the mounting hook 201 is a surface of the mounting hook 201 having a hook shape that faces the keyboard dock 200, that is, a surface that is hooked to the tablet terminal device 100 when connected.

  The button pressing surface 141 presses a fixing button 203 described later when connecting the tablet terminal device 100 to the keyboard dock 200. The button pressing surface 141 is arranged at a position facing the fixing button 203 when the tablet terminal device 100 is connected to the keyboard dock 200. In the present embodiment, the fixing button 203 is disposed at a position moved in the X direction with respect to the attachment opening 101, so that the button pressing surface 141 is provided on the X direction side with respect to the attachment opening 101. . In this case, the button pressing surface 141 may not be provided next to the attachment opening 102.

  Here, the button pressing surface 141 and the hook hooking surface 142 have a positional relationship that satisfies the following conditions. In the following, the positional relationship conditions satisfied by the button pressing surface 141 and the hook hooking surface 142 will be described. When the tablet terminal device 100 is connected to the keyboard dock 200, a plane orthogonal to the insertion direction of the tablet terminal device 100, that is, an XZ plane and a reference plane whose position is fixed with respect to the keyboard dock 200 is 1 Select one. Then, when the tablet terminal device 100 is connected to the keyboard dock 200, the button pressing surface 141 from the reference surface in a state where the fixing button 203 is pressed by the button pressing surface 141 and the mounting hooks 201 and 202 start sliding. The distance up to is the “operation start distance”. In this case, the tablet-type terminal device 100 has a condition that the sum of the distance from the hook hooking surface 142 to the button pressing surface 141 and the operation start distance is not more than the distance from the reference surface to the lower jaw of the mounting hook 201. Meet. By satisfying this condition, when the mounting hook 201 inserted in the mounting opening 101 slides, the mounting hook 201 can slide without contacting the wall forming the mounting opening 101, and the mounting opening 101 can be attached to the mounting opening 101. Engagement with the hook 201 for use is ensured.

  Returning to FIG. 1, the description will be continued. The connector 103 has a line for receiving information input using the keyboard dock 200 and transmitting / receiving other signals to / from the keyboard dock 200. By fixing the tablet terminal device 100 so as not to come out of the keyboard dock 200 by the mounting openings 101 and 102 arranged on both sides of the connector 103, it is possible to prevent the connector 103 from being disconnected.

  The positioning pin insertion holes 104 and 105 are provided at positions opposite to the connector 103 with respect to the mounting openings 101 and 102. The positioning pin insertion holes 104 and 105 are holes for adjusting the connection position of the tablet terminal device 100 to an appropriate position when the tablet terminal device 100 is connected to the keyboard dock 200.

  FIG. 6 is a perspective view of the keyboard dock. The keyboard dock 200 is a function expansion unit connected to the tablet terminal device 100, and provides a user with a function of inputting information to the tablet terminal device 100 using a keyboard. The keyboard dock 200 is an example of “external device”.

  The keyboard dock 200 includes mounting hooks 201 and 202, a fixing button 203, a connector 204, positioning pins 205 and 206, a fixing release button 207, a keyboard 208, and a touch pad 209. FIG. 7 is an enlarged view of the vicinity of the mounting hook.

  The attaching hooks 201 and 202 are fixing parts for connection to the tablet terminal device 100 having a hook shape. The attachment hooks 201 and 202 are arranged on both sides of the connector 204.

  The mounting hook 201 is inserted into the mounting opening 101 at a position before sliding in the reverse X direction. However, the mounting hook 201 has a slope that smoothly spreads in the reverse Y direction at a position facing the tablet terminal device 100 when connected in the reverse X direction. Therefore, even if the mounting hook 201 is slid in the reverse X direction, that is, in a state where the fixing button 203 has been pressed before connection, the slope of the mounting hook 201 remains in the mounting opening 101. Contacting the end, the mounting hook 201 is pushed in the X direction and moves. Thereby, even in this state, the attachment hook 201 is smoothly inserted into the attachment opening 101.

  Then, the attachment hook 201 inserted into the attachment opening 101 slides in the reverse X direction and engages with the attachment opening 101. Further, the attachment hook 202 is inserted into the attachment opening 102. Then, the mounting hook 202 inserted into the mounting opening 102 slides and engages with the mounting opening 102. Since the attachment hook 201 and the attachment hook 202 have the same structure, here, the attachment hook 201 will be described as an example.

  In a state where the mounting hook 201 is engaged with the mounting opening 101, the hook-shaped submandibular portion, that is, the surface facing the reverse Y direction comes into contact with the hook hooking surface 142 of the mounting opening 101. As a result, the attachment hooks 201 and 202 prevent the tablet-type terminal device 100 from moving in the Y direction, that is, the direction in which it is removed from the keyboard dock 200. Thereby, the tablet terminal device 100 is fixed so as not to come out of the keyboard dock 200.

  Further, the attachment hooks 201 and 202 prevent the tablet-type terminal device 100 from moving in the X direction because the side surfaces in the reverse X direction come into contact with the side surfaces of the opening portions of the attachment openings 101 and 102.

  Furthermore, the attachment hook 201 is slid in the reverse X direction when a later-described fixing release button 207 is pressed while the tablet terminal device 100 and the keyboard dock 200 are connected. As a result, the engagement between the mounting hook 201 and the mounting opening 101 is released. In this case, the tablet terminal device 100 can be removed from the keyboard dock 200.

  The fixing button 203 is a button for operating the attachment hooks 201 and 202. In this embodiment, the fixing button 203 is arranged next to the attachment hook 201 on the X direction side.

  The fixing button 203 prevents the attachment hooks 201 and 202 from sliding in the reverse X direction before the tablet terminal device 100 is connected. When the tablet terminal device 100 is inserted, the fixing button 203 comes into contact with the button pressing surface 141 on the side surface of the end portion in the reverse Y direction of the tablet terminal device 100 and is pressed. When the fixing button 203 is pressed by the button pressing surface 141, the fixing hooks 201 and 202 are prevented from being prevented from sliding in the reverse X direction. As a result, the attachment hooks 201 and 202 slide in the reverse X direction and engage with the attachment openings 101 and 102. The fixing button 203 is an example of an “actuation button”.

  The connector 204 has a line for transferring information input from the keyboard 208 and the touch pad 209. When the tablet terminal device 100 is connected to the keyboard dock 200, the connector 204 is connected to the connector 103, and both lines are connected. As a result, information input from the keyboard 208 and the touch pad 209 is transmitted to the CPU of the tablet terminal device 100 via the connectors 204 and 103.

  The positioning pins 205 and 206 are arranged at positions opposite to the connector 204 with respect to the mounting hooks 201 and 202. The positioning pins 205 and 206 are projecting portions that project from the housing of the keyboard dock 200 in the direction toward the inserted tablet terminal device 100.

  The positioning pins 205 and 206 are inserted into the positioning pin insertion holes 104 and 105, respectively. The inserted positioning pins 205 and 206 are in contact with the positioning pin insertion holes 104 and 105 and prevent the tablet terminal device 100 from moving in the X direction and the reverse X direction, and the Y direction and the reverse Y direction. Thereby, the positioning pins 205 and 206 guide the position of the tablet terminal device 100 to an appropriate position when the tablet terminal device 100 is connected to the keyboard dock 200.

  The fixing release button 207 is a button for releasing the engagement between the attachment hooks 201 and 202 and the attachment openings 101 and 102. In this embodiment, the fixing release button 207 is arranged on the same surface as the touch panel 11 in a state where the tablet terminal device 100 is connected to the keyboard dock 200.

  The unlock button 207 is pressed by the user in a state where the tablet terminal device 100 and the keyboard dock 200 are connected and fixed. When the fixing release button 207 is pressed by the user, the attachment hooks 201 and 202 slide in the X direction, and the connection between the tablet terminal device 100 and the keyboard dock 200 is released.

  The keyboard 208 and the touch pad 209 are input devices. The user can input characters using the keyboard 208 or can input the position of the pointer using the touch pad 209.

  Further, in the keyboard dock 200, the connection portion 210 provided with the mounting hooks 201 and 202, the fixing button 203, the connector 204, the positioning pins 205 and 206, and the fixing release button 207 rotates around the X direction. .

  FIG. 8 is a perspective view of a connection state between the tablet terminal device and the keyboard dock. When the tablet terminal device 100 is inserted and connected to the keyboard dock 200, the tablet terminal device 100 enters the state shown in FIG. In this state, the attachment hooks 201 and 202 are engaged with the attachment openings 101 and 102. The connector 204 and the connector 103 are in a connected state. Further, the positioning pins 205 and 206 are inserted into the positioning pin insertion holes 104 and 105.

  Furthermore, the tablet terminal device 100 and the keyboard dock 200 in the state shown in FIG. 8 can be folded into the state shown in FIG. FIG. 9 is a perspective view of the connected tablet terminal device and keyboard dock in a folded state. As shown in FIG. 9, the tablet terminal device 100 can be easily carried while being connected to the keyboard dock 200 by being folded. Specifically, when the connection unit 210 of the keyboard 208 is rotated, the tablet terminal device 100 is rotated and folded together with the connection unit 210.

  Furthermore, with reference to FIGS. 10-12, the mechanism of the connection part of the tablet-type terminal device 100 and the keyboard dock 200 is demonstrated in detail. FIG. 10 is a diagram for explaining a state before connection of the tablet terminal device and the keyboard dock according to the first embodiment. FIG. 11 is a diagram for explaining a state during connection of the tablet terminal device and the keyboard dock according to the first embodiment. FIG. 12 is a diagram for explaining a connection completion state of the tablet terminal device and the keyboard dock according to the first embodiment.

  As shown in FIG. 10, the button pressing surface 141 is not in contact with the fixing button 203 before connection. That is, since the fixing button 203 is not pressed, the amount of protrusion from the housing of the keyboard dock 200 to the outside is in a maximum state.

  The mounting hook 201 is in a state before sliding in the reverse X direction. That is, the attachment hook 201 is in a position where it does not come into contact with the tablet terminal device 100 when the tablet terminal device 100 is inserted into the keyboard dock 200. The mounting hook 201 is connected to the movement preventing member 212.

  A force pulled in the reverse X direction is applied to the mounting hook 201. However, since the movement preventing member 212 is in contact with the fixing button 203 and the movement in the reverse X direction is hindered, the mounting hook 201 is stopped without sliding in the reverse X direction.

  Here, one fixed XZ plane is selected with respect to the connecting portion 210 as a reference plane P. Here, the surface of the connection part 210 that faces the tablet terminal device 100 at the time of connection is defined as a reference plane P. The distance from the lower jaw 211 of the mounting hook 201 to the reference plane P is defined as a distance L1. Further, the distance from the button pressing surface 141 to the hook hooking surface 142 is a distance L2.

  Then, when the tablet terminal device 100 is advanced in the reverse Y direction from the state of FIG. 10, the attachment hook 201 is inserted into the attachment opening 101. Then, the fixing button 203 comes into contact with the button pressing surface 141 and is pressed. Thereafter, when the button pressing surface 141 is pressed, the fixing button 203 sinks in the reverse Y direction, and the contact between the fixing button 203 and the movement preventing member 212 is released. As a result, the mounting hook 201 does not have the force to hinder the movement in the reverse X direction, and thus starts to move in the reverse X direction. This state is the state shown in FIG.

  Here, the distance from the button pressing surface 141 in the state of FIG. 11 to the reference surface P is L3. This L3 corresponds to the operation start distance described above. In this case, the fixing button 203 is in contact with the button pressing surface 141, and the reference plane P is the surface of the connecting portion 210 facing the tablet terminal device 100 at the time of connection. It can also be said that the amount of protrusion of the button 203 from the reference plane.

  Here, as described above, in the tablet terminal device 100 according to the present embodiment, the sum of the distance from the hook hooking surface 142 to the button pressing surface 141 and the operation start distance is the chin of the mounting hook 201 from the reference surface. The condition that the distance to the lower 211 is not more than the condition is satisfied. That is, the tablet terminal device 100 and the keyboard dock 200 satisfy L1 ≧ L2 + L3. L2 + L3 corresponds to the distance from the reference plane P to the hook hooking surface 142. That is, in the state where the mounting hook 201 shown in FIG. 11 starts to move in the reverse X direction, the distance from the reference surface P of the submandibular 211 of the mounting hook 201 is the distance from the reference surface P to the hook hooking surface 142. Longer than. Therefore, the mounting hook 201 can slide in the reverse X direction without contacting the front cover 12 and the core cover 14, and can reliably engage with the mounting opening 101.

  After the state shown in FIG. 11, the mounting hook 201 engages with the wall having the hook hooking surface 142 that forms the mounting opening 101, and the tablet terminal device 100 and the keyboard dock 200 are shown in FIG. 12. Transition to the represented state. Thereby, the connection between the tablet terminal device 100 and the keyboard dock 200 is completed.

  FIG. 13 is a perspective view illustrating a connection state of the tablet terminal device and the keyboard dock according to the first embodiment. In the state shown in FIGS. 12 and 13, when the tablet terminal device 100 is pulled in the Y direction, the lower jaw 211 of the mounting hook 201 contacts the hook hooking surface 142, and the tablet terminal device 100 moves in the Y direction. Inhibits movement. Thereby, it can be said that the tablet terminal device 100 cannot be removed from the keyboard dock 200 and the connection between the tablet terminal device 100 and the keyboard dock 200 is fixed.

  Here, with reference to FIG. 14 and 15, the difference in the certainty of engagement of the tablet terminal device 100 according to the present embodiment and the conventional tablet terminal device will be described. FIG. 14 is a diagram illustrating a state transition at the time of connection in a conventional tablet terminal device. FIG. 15 is a diagram illustrating a state transition at the time of connection when there is a gap in the tablet terminal device according to the first embodiment.

  FIG. 14 shows the connection in a state where a gap is generated between the front cover 33 and the core cover 34 as shown in a region 311. A state 301 represents the state of the conventional tablet terminal device and keyboard dock before the start of connection. The states 302 to 303 represent states in the middle of connection started from the state 301, and the state 304 represents a connection completion state.

  In the conventional tablet terminal device, the fixing button 32 is pressed by a part of the front cover 33. That is, as shown in the state 302, the attachment hook 31 is inserted into the attachment opening 35, and the fixing button 32 contacts the front cover 33.
