[Technical field]

[0001] The present invention relates to an attachment for a game controller that is used in conjunction with a game controller. [Background technology]

[0002] Conventionally, there are accessory devices that are used together with a game controller by fitting the game controller into the accessory device (for example, see Non-Patent Document 1). For example, Non-Patent Document 1 discloses an operation method in which a game controller is attached to a steering wheel-shaped accessory device and the entire accessory device is rotated to operate it. [Prior art documents] [Non-patent literature]

[0003] [Non-Patent Document 1] "Wii Wheel Accessory for the Wii Remote Operations Manual", Nintendo Co., Ltd., p2-4 Summary of the Invention [Problem to be solved by the invention]

[0004] However, there is room for improvement in the convenience of using the above-mentioned accessories together with the game controller.

[0005] Therefore, an object of the present invention is to provide a more convenient attachment for a game controller. [Means for solving the problem]

[0006] In order to achieve the above object, the present invention may employ, for example, the following configurations.

[0007] A first configuration example of the attachment device of the present invention is used with a game controller having at least a first button and a second button. The attachment device includes a fixed part, a grip part, a first movable part, and a second movable part. The game controller is detachably fixed to the fixed part. The grip part can be held by both hands of a user. The first movable part includes a first operation part and a first button pressing part. The first operation part can be pressed by one hand of a user holding the grip part. The first button pressing part can press the first button of the game controller fixed to the fixed part by moving toward the first button of the game controller fixed to the fixed part in response to a pressing operation on the first operation part. The second movable part includes a second operation part and a second button pressing part. The second operation part can be pressed by the other hand of a user holding the grip part. The second button pressing part can press the second button of the game controller fixed to the fixed part by moving toward the second button of the game controller fixed to the fixed part in response to a pressing operation on the second operation part.

[0008] According to the above, by holding the accessory device and moving multiple movable parts provided on the accessory device, multiple buttons provided on a game controller fixed to the accessory device can be operated, thereby improving the convenience of the accessory device.

[0009] The first button pressing portion may be capable of pressing a first button of a game controller fixed to the fixed portion in response to a pressing operation on the first operation portion by protruding from an upper surface of the fixed portion toward a first button of the game controller fixed to the fixed portion, and the second button pressing portion may be capable of pressing a second button of the game controller by protruding from an upper surface of the fixed portion toward a second button of the game controller fixed to the fixed portion in response to a pressing operation on the second operation portion.

[0010] Based on the above, it becomes possible to perform a pressing operation on the first button and the second button of the game controller.

[0011] The first movable part may be configured such that, when a first button of the game controller is changed from a non-pressed state to a pressed state by a press operation, the amount of movement of the first button press part toward the first button of the game controller fixed to the fixed part is smaller than the amount of movement of the first operation part when pressed. The second movable part may be configured such that, when a second button of the game controller is changed from a non-pressed state to a pressed state by a press operation, the amount of movement of the second button press part toward the second button of the game controller fixed to the fixed part is smaller than the amount of movement of the second operation part when pressed.

[0012] Based on the above, it is possible to improve the operational feel when operating the first button and the second button.

[0013] The first movable part may further include a first shaft part and a first arm part. The first arm part rotates around the first shaft part and is connected to the first operation part and the first button pressing part. The second movable part may further include a second shaft part and a second arm part. The second arm part rotates around the second shaft part and is connected to the second operation part and the second button pressing part.

[0014] Based on the above, a plurality of buttons provided on the game controller can be operated using the leverage function.

[0015] The first arm may be formed such that the distance between the first operation portion and the first shaft is longer than the distance between the first button depression portion and the first shaft, and the second arm may be formed such that the distance between the second operation portion and the second shaft is longer than the distance between the second button depression portion and the second shaft.

[0016] Based on the above, a plurality of buttons provided on the game controller can be operated with a small operating force.

[0017] The first button pressing portion may be formed with a chamfered shape of a first chamfer amount at an end closest to the first shaft on a surface that can contact the first button, and with a chamfered shape of a smaller chamfer amount at an end furthest from the first shaft on the contact surface. The second button pressing portion may be formed with a chamfered shape of a second chamfer amount at an end closest to the second shaft on a surface that can contact the second button, and with a chamfered shape of a smaller chamfer amount at an end furthest from the second shaft on the contact surface.

[0018] Furthermore, the first button pressing part may have a surface capable of contacting the first button, a chamfered shape with a first chamfering amount formed at an end portion that approaches the first button first when moving toward the first button of the game controller fixed to the fixed part, and a chamfered shape with a smaller chamfering amount than the first chamfering amount formed at an opposite end portion facing the end portion on the contactable surface. The second button pressing part may have a surface capable of contacting the second button, a chamfered shape with a second chamfering amount formed at an end portion that approaches the second button first when moving toward the second button of the game controller fixed to the fixed part, and a chamfered shape with a smaller chamfering amount than the second chamfering amount formed at an opposite end portion facing the end portion on the contactable surface.

[0019] The first movable part may have a first button depression part formed at a position shifted a predetermined distance in the axial direction of the first shaft from a position where the first operation part is provided, and the second movable part may have a second button depression part formed at a position shifted a predetermined distance in the axial direction of the second shaft from a position where the second operation part is provided.

[0020] Based on the above, there is no restriction on the position of the attached game controller, and it is possible to provide a degree of freedom in designing the arrangement of the first operating unit and the second operating unit.

[0021] The first movable part may have a first button depression part formed at a position shifted a predetermined distance in a direction from the front to the rear from a position where the first operation part is provided, and the second movable part may have a second button depression part formed at a position shifted a predetermined distance in a direction from the front to the rear from a position where the second operation part is provided.

[0022] Based on the above, it is possible to freely arrange the first operation unit and the second operation unit without being restricted by the position of the attached game controller.

[0023] Furthermore, in a direction from the front to the rear, a portion of the first operation unit that can be contacted by a user's finger and that is located closest to the front side may be located on the rear side of a portion of a surface of the first button that can be contacted by the first button in a first button pressing portion. In a direction from the front to the rear, a portion of the second operation unit that can be contacted by a user's finger and that is located closest to the front side may be located on the rear side of a portion of a surface of the second button that can be contacted by the second button in a second button pressing portion.

[0024] Based on the above, there is no restriction on the position of the attached game controller, and it is possible to provide a degree of freedom in designing the arrangement of the first operating unit and the second operating unit.

[0025] Furthermore, a width of a portion where the first button is pressed in the predetermined direction may be larger than a width of the first button in the predetermined direction.A width of a portion where the second button is pressed in the predetermined direction may be larger than a width of the second button in the predetermined direction.

[0026] Based on the above, it is possible to reduce excessive load on the first button and the second button caused by pressing the first button or the second button.

[0027] The predetermined direction may be a direction from the front to the back.

[0028] Based on the above, it is possible to reduce excessive load on the first button and the second button caused by the first button pressing portion and the second button pressing portion.

[0029] The fixing portion may further include at least a first biasing portion and a second biasing portion. The first biasing portion biases the game controller in a direction substantially opposite to a direction in which the first button of the game controller is pressed down by the first button pressing portion when the game controller is fixed to the fixing portion. The second biasing portion biases the game controller in a direction substantially opposite to a direction in which the second button of the game controller is pressed down by the second button pressing portion when the game controller is fixed to the fixing portion, and is provided to the right of the first biasing portion.

[0030] Based on the above, it becomes possible to stably press the first button and the second button.

[0031] The first biasing portion may be provided within the fixed portion directly below the first button depression portion or to the left of the position directly below. The second biasing portion may be provided within the fixed portion directly below the second button depression portion or to the right of the position directly below.

[0032] Based on the above, it becomes possible to press the first button and the second button more stably.

[0033] The fixing portion may be formed with a recess that exposes a part of a side surface of the game controller to the outside when the game controller is fixed to the fixing portion.

[0034] Based on the above, it becomes easy to remove the game controller from the accessory device.

[0035] The first and second operating parts may be disposed on a rear surface of the accessory device. The accessory device may further include a protruding part fixed to the grip part further rearward than the positions where the first and second operating parts are disposed.

[0036] Based on the above, it is possible to reduce the impact applied to the first operating unit and the second operating unit when, for example, the accessory device comes into contact with a floor surface or the like.

[0037] The gripping portion may have a rim portion having a substantially circular periphery.

[0038] According to the above, an operation such as gripping the grip portion and rotating the entire accessory device can be easily performed.

[0039] The rim portion may be formed by joining a front portion that is the front side of the accessory device and a rear portion that is the rear side of the accessory device. The joining surface where the front portion and the rear portion are joined may be located such that the inside of the rim portion is closer to the front side than the outside of the rim portion.

[0040] Based on the above, the feel when gripping the grip portion can be improved.

[0041] A second configuration example of the attachment device of the present invention is used with a first game controller having a protrusion on its back surface and a second game controller having a different shape from the first game controller and having a protrusion on its back surface. The attachment device includes a fixing portion. The fixing portion is detachable from either the first game controller or the second game controller, and one of the fixing portion is detachably fixed. The fixing portion includes a first engaging portion and a second engaging portion. The first engaging portion is provided on one side in a predetermined direction, and engages with the protrusion on the back surface of the first game controller. The second engaging portion is provided on the other side in the predetermined direction, and engages with the protrusion on the back surface of the second game controller.

[0042] Based on the above, it is possible to configure an accessory device that is detachable from any of game controllers of different shapes.

[0043] The first engagement portion may be a recessed portion that engages with a protrusion formed on the back surface of the first game controller when the first game controller is fixed to the fixed portion, and the second engagement portion may be a recessed portion that engages with a protrusion formed on the back surface of the second game controller when the second game controller is fixed to the fixed portion.

[0044] According to the above, by separately forming a recess shape that engages with a protrusion formed on the back of the first game controller and a recess shape that engages with a protrusion formed on the back of the second game controller, it is possible to form an accessory device that can be attached and detached to any game controller of different shapes.

[0045] The first game controller may have at least a first operation input unit. The second game controller may have at least a second operation input unit. The accessory device may have a first marker and a second marker. The first marker is provided at a position that is substantially aligned with the first operation input unit when a protrusion on the back surface of the first game controller engages with a first engagement portion provided on one side of the fixed portion. The second marker is provided at a position that is substantially aligned with the second operation input unit when a protrusion on the back surface of the second game controller engages with a second engagement portion provided on the other side of the fixed portion.

[0046] Based on the above, it becomes possible for the user to intuitively grasp the direction and position in which to attach the first controller and the second game controller to the accessory device.

[0047] Moreover, the first game controller may have at least a first button. The second game controller may have at least a second button. The accessory device may further include a first movable part and a grip part. The grip part can be held by both hands of a user. The first movable part may include a first operation part and a first button pressing part. The first operation part can be pressed by one hand of a user holding the grip part. The first button pressing part moves toward the game controller fixed to the fixed part in response to a pressing operation on the first operation part, so that when a protrusion on the back surface of the first game controller and a first engagement part of the fixed part engage, the first button can be pressed, and when a protrusion on the back surface of the second game controller and a second engagement part of the fixed part engage, the second button can be pressed.

[0048] According to the above, by moving the movable part provided on the accessory device while holding the accessory device, it is possible to operate the buttons on any game controller attached to the accessory device.

[0049] The first game controller may further include a third button. The second game controller may further include a fourth button. The accessory device may further include a second movable part. The second movable part includes a second operation part and a second button pressing part. The second operation part can be pressed by the other hand of the user holding the grip part. The second button pressing part moves toward the game controller fixed to the fixed part in response to a pressing operation on the second operation part, so that when the protruding part on the back surface of the first game controller and the first engagement part of the fixed part engage, the third button can be pressed, and when the protruding part on the back surface of the second game controller and the second engagement part of the fixed part engage, the fourth button can be pressed.

[0050] According to the above, by moving multiple movable parts provided on the accessory device while holding the accessory device, it is possible to operate multiple buttons on the game controller regardless of which game controller is attached to the accessory device, making it possible to perform a variety of operations using the accessory device.

[0051] The first game controller may have a first length defined as a length from the left end of the first game controller, which becomes the left side when the first engagement part of the fixing part is engaged, to a first button, and a third length defined as a length from the right end of the first game controller, which becomes the right side when engaged, to a third button. The second game controller may have a second length longer than the first length defined as a length from the left end of the second game controller, which becomes the left side when the second engagement part of the fixing part is engaged, to a second button, and a fourth length shorter than the third length defined as a length from the right end of the second game controller, which becomes the right side when engaged, to a fourth button. In this case, the fixed portion may have a second length defined as the length from the left end face that can abut against the left end of the second game controller when the protrusion on the back of the second game controller engages with the second engagement portion of the fixed portion to a position where the first button pressing portion protrudes, and a third length defined as the length from the right end face that can abut against the right end of the first game controller when the protrusion on the back of the first game controller engages with the first engagement portion of the fixed portion.

[0052] According to the above, even if the positions of the buttons are different, by mounting the game controllers with the game controllers shifted to the left or right, it is possible to press the buttons by using the same multiple movable parts.

[0053] The first movable part may further include a first shaft part and a first arm part. The first arm part rotates around the first shaft part and is connected to the first operation part and the first button pressing part. The second movable part may further include a second shaft part and a second arm part. The second arm part rotates around the second shaft part and is connected to the second operation part and the second button pressing part.

[0054] Based on the above, a plurality of buttons provided on the game controller can be operated using the leverage function.

[0055] The first arm may be formed such that the distance between the first operation portion and the first shaft is longer than the distance between the first button depression portion and the first shaft, and the second arm may be formed such that the distance between the second operation portion and the second shaft is longer than the distance between the second button depression portion and the second shaft.

[0056] Based on the above, a plurality of buttons provided on the game controller can be operated with a small operating force.

[0057] The first movable part may have a first button depression part formed at a position shifted a predetermined distance in the axial direction of the first shaft from a position where the first operation part is provided, and the second movable part may have a second button depression part formed at a position shifted a predetermined distance in the axial direction of the second shaft from a position where the second operation part is provided.

[0058] Based on the above, there is no restriction on the position of the attached game controller, and it is possible to provide a degree of freedom in designing the arrangement of the first operating unit and the second operating unit.

[0059] The first movable part may be configured such that, when a first button of a first game controller is changed from a not-pressed state to a pressed state by a press operation, an amount by which the first button press part moves toward the first button of the first game controller engaged with the first engagement part of the fixed part is smaller than an amount by which the first operation part is pressed. The second movable part may be configured such that, when a second button of a second game controller is changed from a not-pressed state to a pressed state by a press operation, an amount by which the second button press part moves toward the second button of the second game controller engaged with the second engagement part of the fixed part is smaller than an amount by which the second operation part is pressed.

[0060] Based on the above, it is possible to improve the operational feel when operating each button.

[0061] Furthermore, the first and second game controllers may have a fifth length in a vertical direction that becomes vertical when fixed to the fixing part, and a sixth length in a left-right direction that becomes horizontal when fixed to the fixing part. The fixing part may be formed with a length capable of fixing an object having a fifth length in the vertical direction to which the first game controller or the second game controller is attached. The fixing part may be formed with a length in the left-right direction to which the first game controller or the second game controller is attached that is relatively longer than the sixth length.

[0062] Based on the above, it becomes possible to accommodate game controllers of different shapes by absorbing dimensional differences due to different shapes.

[0063] The fixing part may further include at least two biasing parts that bias the first game controller from above and below when the protrusion on the back surface of the first game controller engages with the first engagement part of the fixing part and when the protrusion on the back surface of the second game controller engages with the second engagement part of the fixing part, respectively, to fix the controllers.

[0064] Based on the above, the game controller can be stably attached to the accessory device. Effect of the Invention

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0067] An information processing system according to an example of this embodiment will be described below. An example of the information processing system in this embodiment is composed of a main unit (information processing device; in this embodiment, it functions as a game device main unit) 2, a left controller 3, a right controller 4, and a steering wheel type attachment 200. The main unit 2 has the left controller 3 and the right controller 4 that are detachable, and the left controller 3 and the right controller 4 can be attached to the main unit 2 and used as an integrated device, or the main unit 2 and the left controller 3 and the right controller 4 can be used separately (see FIG. 2). The information processing system can be used in a form in which an image is displayed on the main unit 2, or in a form in which an image is displayed on another display device such as a television (for example, a stationary monitor). In the former form, the information processing system can be used as a portable device (for example, a portable game machine). In the latter form, the information processing system can be used as a stationary device (for example, a stationary game machine). Furthermore, the steering wheel type attachment 200 in the information processing system can be used as an extended operation device by attaching one of the left controller 3 and the right controller 4 to a part of it. As will be made clear later, either the left controller 3 or the right controller 4 can be detachably attached to the steering wheel type attachment 200. Furthermore, the "accessory device" in this application also includes devices such as so-called extended devices and attachments.

[0068] FIG. 1 is a diagram showing a state in which a left controller 3 and a right controller 4 are attached to a main unit 2. As shown in FIG. 1, the left controller 3 and the right controller 4 are each attached to and integrated with the main unit 2. The main unit 2 is a device that executes various processes (e.g., game processes) in an information processing system. The main unit 2 includes a display 12. The left controller 3 and the right controller 4 are devices that include an operation unit that allows the user to perform input.

[0069] FIG. 2 is a diagram showing an example of a state in which the left controller 3 and the right controller 4 are respectively removed from the main unit 2. As shown in FIG. 1 and FIG. 2, the left controller 3 and the right controller 4 are detachable from the main unit 2. The left controller 3 can be attached to the left side surface of the main unit 2 (the side surface on the x-axis positive side shown in FIG. 1), and can be attached to and detached from the main unit 2 by sliding it along the left side surface of the main unit 2 in the y-axis direction shown in FIG. 1. The right controller 4 can be attached to the right side surface of the main unit 2 (the side surface on the x-axis negative side shown in FIG. 1), and can be attached to and detached from the main unit 2 by sliding it along the right side surface of the main unit 2 in the y-axis direction shown in FIG. 1. In the following, the left controller 3 and the right controller 4 may be collectively referred to as "controllers". In this embodiment, the "operation device" operated by one user may be one controller (e.g., one of the left controller 3 and the right controller 4) or multiple controllers (e.g., both the left controller 3 and the right controller 4, or may further include other controllers), and the "operation device" can be configured by one or more controllers. Also, in this embodiment, by attaching one controller (e.g., the right controller 4) to an accessory device (e.g., the steering wheel-type attachment 200), the user can control information processing (e.g., game processing) being executed in the main unit 2 by operating the accessory device. An example of a specific configuration of the main unit 2, the left controller 3, and the right controller 4 will be described below.

[0070] FIG. 3 is a six-sided view showing an example of the main unit 2. As shown in FIG. 3, the main unit 2 includes a housing 11 having a substantially plate-like shape. In this embodiment, the main surface of the housing 11 (in other words, the front surface, i.e., the surface on which the display 12 is provided) is generally rectangular. In this embodiment, the housing 11 is assumed to have a horizontally long shape. That is, in this embodiment, the longitudinal direction of the main surface of the housing 11 (i.e., the x-axis direction shown in FIG. 1) is referred to as the horizontal direction (also referred to as the left-right direction), the short-side direction of the main surface (i.e., the y-axis direction shown in FIG. 1) is referred to as the vertical direction (also referred to as the up-down direction), and the direction perpendicular to the main surface (i.e., the z-axis direction shown in FIG. 1) is referred to as the depth direction (also referred to as the front-rear direction). The main unit 2 can be used in a horizontal orientation. The main unit 2 can also be used in a vertical orientation. In that case, the housing 11 may be regarded as having a vertically long shape.

[0071] The shape and size of the housing 11 are arbitrary. As an example, the housing 11 may be of a size that is portable. Furthermore, the main unit 2 alone or an integrated device in which the left controller 3 and the right controller 4 are attached to the main unit 2 may be a portable device. Furthermore, the main unit 2 or the integrated device may be a handheld device. Furthermore, the main unit 2 or the integrated device may be a portable device.

[0072] 3, the main unit 2 includes a display 12 provided on a main surface of a housing 11. The display 12 displays an image (which may be a still image or a moving image) acquired or generated by the main unit 2. In this embodiment, the display 12 is a liquid crystal display (LCD). However, the display 12 may be any type of display device.

[0073] The main unit 2 also includes a touch panel 13 on the screen of the display 12. In this embodiment, the touch panel 13 is of a type that allows multi-touch input (for example, a capacitive type). However, the touch panel 13 may be of any type, and may be of a type that allows single-touch input (for example, a resistive film type).

[0074] The main unit 2 includes a speaker (i.e., speaker 88 shown in FIG. 6) inside the housing 11. As shown in FIG. 3, speaker holes 11a and 11b are formed in the main surface of the housing 11. The output sound of the speaker 88 is output from these speaker holes 11a and 11b, respectively.

[0075] As shown in FIG. 3, the main unit 2 includes a left rail member 15 on the left side surface of the housing 11. The left rail member 15 is a member for removably mounting the left controller 3 to the main unit 2. The left rail member 15 is provided on the left side surface of the housing 11 so as to extend along the up-down direction. The left rail member 15 has a shape that allows it to engage with the slider of the left controller 3 (i.e., the slider 40 shown in FIG. 4), and the left rail member 15 and the slider 40 form a slide mechanism. This slide mechanism allows the left controller 3 to be slidably and detachably mounted to the main unit 2.

[0076] The main unit 2 also includes a left side terminal 17. The left side terminal 17 is a terminal through which the main unit 2 performs wired communication with the left controller 3. The left side terminal 17 is provided at a position that contacts a terminal of the left controller 3 (terminal 42 shown in FIG. 4) when the left controller 3 is attached to the main unit 2. The specific position of the left side terminal 17 is arbitrary. In this embodiment, as shown in FIG. 3, the left side terminal 17 is provided on the bottom surface of the left rail member 15. In this embodiment, the left side terminal 17 is provided near the lower end of the bottom surface of the left rail member 15, and is disposed at a position that is not exposed to the outside by a part of the left rail member 15.

[0077] As shown in FIG. 3, the right side surface of the housing 11 is provided with a configuration similar to that provided on the left side surface. That is, the main unit 2 is provided with a right rail member 19 on the right side surface of the housing 11. The right rail member 19 is provided on the right side surface of the housing 11 so as to extend along the up-down direction. The right rail member 19 has a shape that can be engaged with the slider of the right controller 4 (i.e., the slider 62 shown in FIG. 5), and the right rail member 19 and the slider 62 form a slide mechanism. This slide mechanism allows the right controller 4 to be slidably and detachably attached to the main unit 2.

[0078] The main unit 2 also includes a right side terminal 21. The right side terminal 21 is a terminal through which the main unit 2 performs wired communication with the right controller 4. The right side terminal 21 is provided at a position that contacts a terminal of the right controller 4 (terminal 64 shown in FIG. 5) when the right controller 4 is attached to the main unit 2. The specific position of the right side terminal 21 is arbitrary. In this embodiment, as shown in FIG. 3, the right side terminal 21 is provided on the bottom surface of the right rail member 19. Also, in this embodiment, the right side terminal 21 is provided near the lower end of the bottom surface of the right rail member 19, and is disposed at a position that is not exposed to the outside by a part of the right rail member 19.

[0079] As shown in FIG. 3, the main unit 2 includes a first slot 23. The first slot 23 is provided on the upper side of the housing 11. The first slot 23 has a shape that allows a first type of storage medium to be attached thereto. The first type of storage medium is, for example, a storage medium (for example, a dedicated memory card) dedicated to an information processing system and the same type of information processing device. The first type of storage medium is used, for example, to store data used in the main unit 2 (for example, save data of an application, etc.) and / or a program executed in the main unit 2 (for example, a program of an application, etc.). The main unit 2 also includes a power button 28. As shown in FIG. 3, the power button 28 is provided on the upper side of the housing 11. The power button 28 is a button for switching the power of the main unit 2 on / off.

[0080] The main unit 2 includes an audio input / output terminal (specifically, an earphone jack) 25. That is, the main unit 2 can have a microphone or earphones attached to the audio input / output terminal 25. As shown in FIG. 3, the audio input / output terminal 25 is provided on the upper side surface of the housing 11.

[0081] The main unit 2 includes volume buttons 26a and 26b. As shown in Fig. 3, the volume buttons 26a and 26b are provided on the upper side surface of the housing 11. The volume buttons 26a and 26b are buttons for issuing an instruction to adjust the volume output by the main unit 2. In other words, the volume button 26a is a button for issuing an instruction to turn down the volume, and the volume button 26b is a button for issuing an instruction to turn up the volume.

[0082] Further, exhaust hole 11c is formed in housing 11. As shown in Fig. 3, exhaust hole 11c is formed on the upper side surface of housing 11. Exhaust hole 11c is formed in order to exhaust (in other words, release) heat generated inside housing 11 to the outside of housing 11. In other words, exhaust hole 11c can also be said to be a heat exhaust hole.

[0083] The main unit 2 includes a lower terminal 27. The lower terminal 27 is a terminal for the main unit 2 to communicate with the cradle. As shown in FIG. 3, the lower terminal 27 is provided on the lower side of the housing 11. When the main unit 2 is attached to the cradle, the lower terminal 27 is connected to the terminal of the cradle. In this embodiment, the lower terminal 27 is a USB connector (more specifically, a female connector). The cradle can accommodate only the main unit 2 with the left controller 3 and the right controller 4 removed from the main unit 2. As another example, the cradle can accommodate an all-in-one device with the left controller 3 and the right controller 4 attached to the main unit 2. The cradle can communicate with a stationary monitor (for example, a stationary television) which is an example of an external display device separate from the main unit 2 (this may be wired communication or wireless communication). When the all-in-one device or the main unit 2 is placed on the cradle, the information processing system can display an image acquired or generated by the main unit 2 on the stationary monitor. In the present embodiment, the cradle has a function of charging the placed all-in-one device or the main device 2 alone. The cradle also has a function as a hub device (specifically, a USB hub).

[0084] The main unit 2 also includes a second slot 24. In this embodiment, the second slot 24 is provided on the lower side of the housing 11. However, in other embodiments, the second slot 24 may be provided on the same side as the first slot 23. The second slot 24 has a shape that allows a second type of storage medium different from the first type to be attached. The second type of storage medium may be, for example, a general-purpose storage medium. For example, the second type of storage medium may be an SD card. The second type of storage medium is used, for example, like the first type of storage medium, to store data used in the main unit 2 (for example, application save data, etc.) and / or programs executed in the main unit 2 (for example, application programs, etc.).

[0085] Further, the housing 11 is formed with an intake hole 11d. As shown in Fig. 3, the intake hole 11d is formed on the lower side surface of the housing 11. The intake hole 11d is formed to draw (in other words, introduce) air from outside the housing 11 into the inside of the housing 11. In this embodiment, the intake hole 11d is formed on the surface opposite to the surface on which the exhaust hole 11c is formed, so that heat can be efficiently dissipated from inside the housing 11.

[0086] The shape, number, and installation position of each of the components (specifically, buttons, slots, terminals, etc.) provided in housing 11 described above are arbitrary. For example, in other embodiments, power button 28 and some of slots 23 and 24 may be provided on other sides or the back of housing 11. Also, in other embodiments, main unit 2 may be configured not to include some of the above-mentioned components.

[0087] FIG. 4 is a six-sided view showing an example of the left controller 3. As shown in FIG. 4, the left controller 3 includes a housing 31. In this embodiment, the housing 31 is substantially plate-shaped. The main surface of the housing 31 (in other words, the front surface, i.e., the surface on the z-axis negative side shown in FIG. 1) is substantially rectangular. In this embodiment, the housing 31 is vertically long, that is, long in the up-down direction (i.e., the y-axis direction shown in FIG. 1). The left controller 3 can also be held in a vertical orientation when removed from the main unit 2. The housing 31 has a shape and size that allows it to be held in one hand, particularly the left hand, when held in a vertical orientation. The left controller 3 can also be held in a horizontal orientation. When the left controller 3 is held in a horizontal orientation, it may be held with both hands. The shape of the housing 31 is arbitrary, and in other embodiments, the housing 31 does not have to be substantially plate-shaped. Furthermore, the housing 31 does not have to be rectangular, and may be, for example, semicircular, etc. Furthermore, the housing 31 does not have to be elongated.

[0088] The vertical length of the housing 31 is approximately the same as the vertical length of the housing 11 of the main unit 2. In addition, the thickness of the housing 31 (i.e., the length in the front-rear direction, in other words, the length in the z-axis direction shown in FIG. 1) is approximately the same as the thickness of the housing 11 of the main unit 2. Therefore, when the left controller 3 is attached to the main unit 2 (see FIG. 1), the user can hold the main unit 2 and the left controller 3 as if they were a single device.

[0089] 4, the left corner of the main surface of the housing 31 is rounder than the right corner. That is, the connection portion between the upper side and the left side of the housing 31 and the connection portion between the lower side and the left side of the housing 31 are rounder than the connection portion between the upper side and the right side and the connection portion between the lower side and the right side (in other words, the radius of curvature of the chamfer is larger). Therefore, when the left controller 3 is attached to the main unit 2 (see FIG. 1), the left side of the integrated device has a rounded shape, which makes it easier for the user to hold.

[0090] The left controller 3 includes an analog stick 32. As shown in FIG. 4, the analog stick 32 is provided on the main surface of the housing 31. The analog stick 32 is an example of a direction input unit capable of inputting a direction. The analog stick 32 has a stick member that can be tilted in all directions parallel to the main surface of the housing 31 (i.e., 360° directions including up, down, left, right, and diagonal directions). By tilting the stick member, the user can input a direction according to the tilt direction (and input a magnitude according to the tilt angle). The direction input unit may be a cross key or a slide stick. In addition, in this embodiment, an input of pressing the stick member (in a direction perpendicular to the housing 31) is possible. That is, the analog stick 32 is an input unit that can input a direction and a magnitude according to the tilt direction and tilt amount of the stick member, and can input a press input on the stick member.

[0091] The left controller 3 includes four operation buttons 33 to 36 (specifically, a right direction button 33, a down direction button 34, an up direction button 35, and a left direction button 36). As shown in FIG. 4, these four operation buttons 33 to 36 are provided below the analog stick 32 on the main surface of the housing 31. In the present embodiment, the main surface of the left controller 3 is provided with four operation buttons, but the number of operation buttons is arbitrary. These operation buttons 33 to 36 are used to give instructions according to various programs (for example, OS programs and application programs) executed on the main unit 2. In the present embodiment, the operation buttons 33 to 36 may be used to input directions, and therefore the operation buttons 33 to 36 are referred to as the right direction button 33, the down direction button 34, the up direction button 35, and the left direction button 36. However, the operation buttons 33 to 36 may be used to give instructions other than direction input.

[0092] The left controller 3 also has a record button 37. As shown in Fig. 4, the record button 37 is provided on the main surface of the housing 31, more specifically, in the lower right area of ​​the main surface. The record button 37 is a button for issuing an instruction to save an image displayed on the display 12 of the main unit 2. For example, when a game image is displayed on the display 12, the user can press the record button 37 to save the game image displayed at the time the button was pressed in, for example, a memory unit of the main unit 2.

[0093] The left controller 3 also has a - (minus) button 47 in the shape of the letter "-". As shown in Fig. 4, the - button 47 is provided on the main surface of the housing 31, more specifically, in the upper right region of the main surface. The - button 47 is used to give instructions according to various programs (e.g., OS programs and application programs) executed on the main unit 2. The - button 47 is used, for example, as a select button (e.g., a button used to switch between selection items) in a game application.

[0094] When the left controller 3 is attached to the main unit 2, the operation sections (specifically, the analog stick 32 and the above-mentioned buttons 33 to 37, 47) provided on the main surface of the left controller 3 are operated, for example, by the thumb of the left hand of a user holding the integrated device. When the left controller 3 is detached from the main unit 2 and held sideways with both hands for use, the above-mentioned operation sections are operated, for example, by the thumbs of the left and right hands of a user holding the left controller 3. Specifically, in this case, the analog stick 32 is operated by the thumb of the user's left hand, and the operation buttons 33 to 36 are operated by the thumb of the user's right hand.

[0095] The left controller 3 includes a first L button 38. The left controller 3 also includes a ZL button 39. These operation buttons 38 and 39 are used to give instructions according to various programs executed in the main unit 2, similar to the operation buttons 33 to 36. As shown in FIG. 4, the first L button 38 is provided in the upper left part of the side of the housing 31. The ZL button 39 is provided in the upper left part from the side to the back of the housing 31 (strictly speaking, the upper left part when the housing 31 is viewed from the front side). In other words, the ZL button 39 is provided behind the first L button 38 (the z-axis positive direction side shown in FIG. 1). In this embodiment, since the upper left part of the housing 31 has a rounded shape, the first L button 38 and the ZL button 39 have a rounded shape corresponding to the roundness of the upper left part of the housing 31. When the left controller 3 is attached to the main unit 2, the first L button 38 and the ZL button 39 will be located in the upper left portion of the integrated device.

[0096] The left controller 3 is equipped with the slider 40 described above. As shown in Fig. 4, the slider 40 is provided on the right side surface of the housing 31 so as to extend in the vertical direction. The slider 40 has a shape that allows it to engage with the left rail member 15 of the main unit 2 (more specifically, the groove of the left rail member 15). Therefore, the slider 40 engaged with the left rail member 15 is fixed and cannot be removed in the direction perpendicular to the sliding direction (in other words, the direction in which the left rail member 15 extends).

[0097] The left controller 3 also includes a terminal 42 for wired communication between the left controller 3 and the main unit 2. The terminal 42 is provided at a position that contacts the left side terminal 17 (FIG. 3) of the main unit 2 when the left controller 3 is attached to the main unit 2. The specific position of the terminal 42 is arbitrary. In this embodiment, as shown in FIG. 4, the terminal 42 is provided at a position that is not exposed to the outside due to the attachment surface of the slider 40. Also, in this embodiment, the terminal 42 is provided near the lower end of the attachment surface of the slider 40.

[0098] The left controller 3 also includes a second L button 43 and a second R button 44. These buttons 43 and 44, like the other operation buttons 33 to 36, are used to give instructions according to various programs executed in the main unit 2. As shown in FIG. 4, the second L button 43 and the second R button 44 are provided on the mounting surface of the slider 40. The second L button 43 is provided above the center in the up-down direction (the y-axis direction shown in FIG. 1) on the mounting surface of the slider 40. The second R button 44 is provided below the center in the up-down direction on the mounting surface of the slider 40. The second L button 43 and the second R button 44 are located at positions that cannot be pressed when the left controller 3 is mounted on the main unit 2. In other words, the second L button 43 and the second R button 44 are buttons that are used when the left controller 3 is removed from the main unit 2. The second L button 43 is operated, for example, by the index finger or middle finger of the left hand of a user holding the left controller 3 removed from the main unit 2 in a landscape orientation with the mounting surface of the slider 40 facing up. The second R button 44 is operated, for example, by the index finger or middle finger of the right hand of a user holding the left controller 3 removed from the main unit 2 in a landscape orientation with the mounting surface of the slider 40 facing up. When the left controller 3 is attached to the steering wheel type attachment 200, the second L button 43 and the second R button 44 can be operated by operating the operation units provided on the steering wheel type attachment 200 with the index finger or middle finger of the left or right hand of the user holding the steering wheel type attachment 200.

[0099] The left controller 3 includes a pairing button 46. In this embodiment, the pairing button 46 is used to instruct a setting process (also called pairing) related to wireless communication between the left controller 3 and the main unit 2, and to instruct a reset process of the left controller 3. Note that in other embodiments, the pairing button 46 may have only one of the functions of the setting process and the reset process. For example, when a short press operation is performed on the pairing button 46 (specifically, when the pairing button 46 is pressed for a time shorter than a predetermined time), the left controller 3 executes the setting process. Also, when a long press operation is performed on the pairing button 46 (specifically, when the pairing button 46 is pressed for the predetermined time or longer), the left controller 3 executes a reset process. In this embodiment, the pairing button 46 is provided on the mounting surface of the slider 40, as shown in FIG. 4. In this way, the pairing button 46 is located in a position that is not visible when the left controller 3 is mounted on the main unit 2. In other words, the pairing button 46 is used when the left controller 3 is removed from the main unit 2.

[0100] In this embodiment, the buttons (specifically, the second L button 43, the second R button 44, and the pairing button 46) provided on the mounting surface of the slider 40 are provided so as not to protrude from the mounting surface. That is, the upper surfaces of the above-mentioned buttons (in other words, the pressing surfaces) are arranged on the same surface as the mounting surface of the slider 40, or are arranged at a position recessed from the mounting surface. This allows the slider 40 to slide smoothly relative to the left rail member 15 when the slider 40 is mounted on the left rail member 15 of the main unit 2.

[0101] FIG. 5 is a six-sided view showing an example of the right controller 4. As shown in FIG. 5, the right controller 4 includes a housing 51. In this embodiment, the housing 51 is substantially plate-shaped. The main surface of the housing 51 (in other words, the front surface, i.e., the surface on the z-axis negative side shown in FIG. 1) is substantially rectangular. In this embodiment, the housing 51 is vertically long, that is, long in the up-down direction. The right controller 4 can also be held in a vertical orientation when removed from the main unit 2. The housing 51 has a shape and size that allows it to be held in one hand, particularly the left hand, when held in a vertical orientation. The right controller 4 can also be held in a horizontal orientation. When the right controller 4 is held in a horizontal orientation, it may be held with both hands.

[0102] Like the housing 31 of the left controller 3, the housing 51 of the right controller 4 has a vertical length that is approximately the same as the vertical length of the housing 11 of the main unit 2, and a thickness that is approximately the same as the thickness of the housing 11 of the main unit 2. Therefore, when the right controller 4 is attached to the main unit 2 (see FIG. 1), the user can hold the main unit 2 and the right controller 4 as if they were a single device.

[0103] 5, the right corner of the main surface of the housing 51 is rounder than the left corner. That is, the connection portion between the upper side and the right side of the housing 51 and the connection portion between the lower side and the right side of the housing 51 are rounder than the connection portion between the upper side and the left side and the connection portion between the lower side and the left side (in other words, the radius of curvature of the chamfer is larger). Therefore, when the right controller 4 is attached to the main unit 2 (see FIG. 1), the right side of the integrated device has a rounded shape, which makes it easier for the user to hold.

[0104] The right controller 4, like the left controller 3, has an analog stick 52 as a direction input unit. In this embodiment, the analog stick 52 has the same configuration as the analog stick 32 of the left controller 3. Also, like the left controller 3, the right controller 4 has four operation buttons 53 to 56 (specifically, an A button 53, a B button 54, an X button 55, and a Y button 56). In this embodiment, these four operation buttons 53 to 56 have the same mechanism as the four operation buttons 33 to 36 of the left controller 3. As shown in FIG. 5, these analog stick 52 and each of the operation buttons 53 to 56 are provided on the main surface of the housing 51. Note that, although the number of operation buttons provided on the main surface of the right controller 4 is four in this embodiment, the number of operation buttons is arbitrary.

[0105] Here, in this embodiment, the positional relationship of the two types of operation parts (analog stick and operation buttons) in the right controller 4 is opposite to the positional relationship of these two types of operation parts in the left controller 3. That is, in the right controller 4, the analog stick 52 is arranged above the operation buttons 53 to 56, whereas in the left controller 3, the analog stick 32 is arranged below the operation buttons 33 to 36. With this arrangement, when the left controller 3 and the right controller 4 are used detached from the main unit 2, they can be used with a similar operational feel.

[0106] The right controller 4 also includes a + (plus) button 57 in the shape of the letter "+". As shown in FIG. 5, the + button 57 is provided on the main surface of the housing 51, more specifically, in the upper left region of the main surface. The + button 57, like the other operation buttons 53 to 56, is used to give instructions according to various programs (e.g., OS programs and application programs) executed on the main unit 2. The + button 57 is used, for example, as a start button in a game application (e.g., a button used to give an instruction to start a game).

[0107] The right controller 4 includes a home button 58. As shown in FIG. 5, the home button 58 is provided on the main surface of the housing 51, more specifically, in the lower left region of the main surface. The home button 58 is a button for displaying a predetermined menu screen on the display 12 of the main unit 2. The menu screen is, for example, a screen on which an application designated by the user can be started from one or more applications executable on the main unit 2. The menu screen may be displayed, for example, when the main unit 2 is started. In this embodiment, when the home button 58 is pressed in a state in which an application is being executed on the main unit 2 (i.e., a state in which an image of the application is displayed on the display 12), a predetermined operation screen may be displayed on the display 12 (at this time, a menu screen may be displayed instead of the operation screen). The operation screen is, for example, a screen on which an instruction to end the application and display a menu screen on the display 12 and an instruction to resume the application can be given.

[0108] When the right controller 4 is attached to the main unit 2, the operation sections (specifically, the analog stick 52 and the above-mentioned buttons 53 to 58) provided on the main surface of the right controller 4 are operated, for example, by the thumb of the right hand of the user holding the integrated device. When the right controller 4 is detached from the main unit 2 and held horizontally with both hands for use, the above-mentioned operation sections are operated, for example, by the thumbs of the left and right hands of the user holding the right controller 4. Specifically, in this case, the analog stick 52 is operated by the thumb of the user's left hand, and the operation buttons 53 to 56 are operated by the thumb of the user's right hand.

[0109] The right controller 4 includes a first R button 60. The right controller 4 also includes a ZR button 61. As shown in FIG. 5, the first R button 60 is provided in the upper right portion of the side of the housing 51. The ZR button 61 is provided in the upper right portion from the side to the back of the housing 51 (strictly speaking, in the upper right portion when the housing 51 is viewed from the front side). In other words, the ZR button 61 is provided behind the first R button 60 (the z-axis positive direction side shown in FIG. 1). In this embodiment, since the upper right portion of the housing 51 has a rounded shape, the first R button 60 and the ZR button 61 have a rounded shape corresponding to the roundness of the upper right portion of the housing 51. When the right controller 4 is attached to the main unit 2, the first R button 60 and the ZR button 61 are disposed in the upper right portion of the all-in-one device.

[0110] The right controller 4 has a slider mechanism similar to that of the left controller 3. That is, the right controller 4 has the slider 62 described above. As shown in FIG. 5, the slider 62 is provided on the left side surface of the housing 51 so as to extend in the vertical direction. The slider 62 has a shape that allows it to engage with the right rail member 19 of the main unit 2 (more specifically, the groove of the right rail member 19). Therefore, the slider 62 engaged with the right rail member 19 is fixed and does not come off in the direction perpendicular to the sliding direction (in other words, the direction in which the right rail member 19 extends).

[0111] The right controller 4 also includes a terminal 64 for wired communication between the right controller 4 and the main unit 2. The terminal 64 is provided at a position that contacts the right side terminal 21 (FIG. 3) of the main unit 2 when the right controller 4 is attached to the main unit 2. The specific position of the terminal 64 is arbitrary. In this embodiment, as shown in FIG. 5, the terminal 64 is provided at a position that is not exposed to the outside due to the attachment surface of the slider 62. In this embodiment, the terminal 64 is provided near the lower end of the attachment surface of the slider 62.

[0112] Similarly to the left controller 3, the right controller 4 includes a second L button 65 and a second R button 66. Similarly to the other operation buttons 53 to 56, these buttons 65 and 66 are used to give instructions according to various programs executed in the main unit 2. As shown in FIG. 5, the second L button 65 and the second R button 66 are provided on the mounting surface of the slider 62. The second L button 65 is provided below the center in the up-down direction (the y-axis direction shown in FIG. 1) on the mounting surface of the slider 62. The second R button 66 is provided above the center in the up-down direction on the mounting surface of the slider 62. Similarly to the second L button 43 and the second R button 44 of the left controller 3, the second L button 65 and the second R button 66 are located at positions that cannot be pressed when the right controller 4 is mounted on the main unit 2, and are used when the right controller 4 is removed from the main unit 2. The second L button 65 is operated, for example, by the index finger or middle finger of the left hand of a user holding the right controller 4 removed from the main unit 2 in a landscape orientation with the mounting surface of the slider 62 facing up. The second R button 66 is operated, for example, by the index finger or middle finger of the right hand of a user holding the right controller 4 removed from the main unit 2 in a landscape orientation with the mounting surface of the slider 62 facing up. When the right controller 4 is attached to the steering wheel type attachment 200, the second L button 65 and the second R button 66 can be operated by operating the operation units provided on the steering wheel type attachment 200 with the index finger or middle finger of the left or right hand of the user holding the steering wheel type attachment 200.

[0113] The right controller 4 includes a pairing button 69. Like the pairing button 46 of the left controller 3, the pairing button 69 is used to instruct the setting (also called pairing) process regarding wireless communication between the right controller 4 and the main unit 2, and to instruct the reset process of the right controller 4. The setting process and the reset process are similar to those of the left controller 3, and therefore detailed explanations are omitted. In this embodiment, the pairing button 69 is provided on the mounting surface of the slider 62, as shown in FIG. 5. That is, for the same reason as the pairing button 46 of the left controller 3, the pairing button 69 is located in a position that is not visible when the right controller 4 is mounted on the main unit 2.

[0114] Also, in the right controller 4, like the left controller 3, the buttons (specifically, the second L button 65, the second R button 66, and the pairing button 69) provided on the mounting surface of the slider 62 are provided so as not to protrude from the mounting surface. This allows the slider 62 to slide smoothly along the right rail member 19 when the slider 62 is mounted on the right rail member 19 of the main unit 2.

[0115] In addition, a window portion 68 is provided on the lower side of the housing 51. The right controller 4 is equipped with an infrared imaging unit 123 and an infrared light emitting unit 124 arranged inside the housing 51. The infrared imaging unit 123 captures an image of the periphery of the right controller 4 through the window portion 68, with the imaging direction being the downward direction of the right controller 4 (the negative y-axis direction shown in FIG. 5). The infrared light emitting unit 124 irradiates infrared light through the window portion 68 onto the imaging target member imaged by the infrared imaging unit 123, with an irradiation range being a predetermined range centered on the downward direction of the right controller 4 (the negative y-axis direction shown in FIG. 5).

[0116] The right controller 4 also includes an NFC communication unit 122. The NFC communication unit 122 performs short-distance wireless communication based on the NFC (Near Field Communication) standard. The NFC communication unit 122 has an antenna 122a used for short-distance wireless communication and a circuit (e.g., an NFC chip) that generates a signal (radio wave) to be sent from the antenna 122a. For example, when another wireless communication device (e.g., an NFC tag) that is a target in the short-distance wireless communication is placed in another device that is in close proximity to or in contact with the lower area of ​​the main surface of the housing 51, the antenna 122a is provided at a position inside the housing 51 where the short-distance wireless communication with the wireless communication device is possible. Note that the short-distance wireless communication is not limited to that based on the NFC standard, and may be any short-distance communication (also referred to as non-contact communication). The short-distance communication includes, for example, a communication method in which an electromotive force is generated in another device by radio waves from one device (e.g., by electromagnetic induction).

[0117] In the left controller 3 and right controller 4, the shape, number, and installation position of each component (specifically, slider, stick, button, etc.) provided on the housing 31 or 51 are arbitrary. For example, in other embodiments, the left controller 3 and right controller 4 may be provided with a direction input unit of a type other than an analog stick. The slider 40 or 62 may be disposed at a position corresponding to the position of the rail member 15 or 19 provided on the main unit 2, and may be disposed on the main surface or back surface of the housing 31 or 51, for example. In other embodiments, the left controller 3 and right controller 4 may be configured not to include some of the above-mentioned components.

[0118] Fig. 6 is a block diagram showing an example of the internal configuration of main unit 2. In addition to the configuration shown in Fig. 3, main unit 2 includes components 81-98 shown in Fig. 6. Some of these components 81-98 may be mounted on an electronic circuit board as electronic components and housed in housing 11.

[0119] The main unit 2 includes a CPU (Central Processing Unit) 81. The CPU 81 is an information processing section that executes various types of information processing executed in the main unit 2. The CPU 81 executes various types of information processing by executing an information processing program (e.g., a game program) stored in a storage section (specifically, an internal storage medium such as a flash memory 84, or an external storage medium attached to each of the slots 23 and 24).

[0120] The main device 2 includes a flash memory 84 and a dynamic random access memory (DRAM) 85 as examples of internal storage media built into the main device 2. The flash memory 84 and the DRAM 85 are connected to the CPU 81. The flash memory 84 is a memory used mainly for storing various data (which may be programs) saved in the main device 2. The DRAM 85 is a memory used for temporarily storing various data used in information processing.

[0121] The main device 2 includes a first slot interface (hereinafter abbreviated as "I / F") 91. The main device 2 also includes a second slot I / F 92. The first slot I / F 91 and the second slot I / F 92 are connected to the CPU 81. The first slot I / F 91 is connected to the first slot 23, and reads and writes data from a first type of storage medium (e.g., an SD card) attached to the first slot 23 in response to an instruction from the CPU 81. The second slot I / F 92 is connected to the second slot 24, and reads and writes data from a second type of storage medium (e.g., a dedicated memory card) attached to the second slot 24 in response to an instruction from the CPU 81.

[0122] The CPU 81 executes the above information processing by appropriately reading and writing data from and to the flash memory 84, the DRAM 85, and the above storage media.

[0123] The main unit 2 includes a network communication unit 82. The network communication unit 82 is connected to the CPU 81. The network communication unit 82 communicates with an external device via a network (specifically, wireless communication). In this embodiment, the network communication unit 82 connects to a wireless LAN and communicates with an external device using a method conforming to the Wi-Fi standard as a first communication mode. The network communication unit 82 also performs wireless communication with other main units 2 of the same type using a predetermined communication method (for example, communication using a unique protocol or infrared communication) as a second communication mode. Note that the wireless communication using the second communication mode enables wireless communication with other main units 2 located within a closed local network area, and realizes a function that enables so-called "local communication" in which data is transmitted and received by directly communicating between multiple main units 2.

[0124] The main unit 2 includes a controller communication unit 83. The controller communication unit 83 is connected to the CPU 81. The controller communication unit 83 performs wireless communication with the left controller 3 and / or the right controller 4. Any communication method may be used between the main unit 2 and the left controller 3 and right controller 4, but in this embodiment, the controller communication unit 83 performs communication with the left controller 3 and the right controller 4 in accordance with the Bluetooth (registered trademark) standard.

[0125] The CPU 81 is connected to the above-mentioned left terminal 17, right terminal 21, and lower terminal 27. When the CPU 81 performs wired communication with the left controller 3, it transmits data to the left controller 3 via the left terminal 17 and receives operation data from the left controller 3 via the left terminal 17. When the CPU 81 performs wired communication with the right controller 4, it transmits data to the right controller 4 via the right terminal 21 and receives operation data from the right controller 4 via the right terminal 21. When the CPU 81 communicates with the cradle, it transmits data to the cradle via the lower terminal 27. Thus, in this embodiment, the main unit 2 can perform both wired communication and wireless communication with the left controller 3 and the right controller 4. When the main unit 2 alone or an integrated device with the left controller 3 and the right controller 4 attached to the main unit 2 is attached to the cradle, the main unit 2 can output data (e.g., image data and audio data) to a stationary monitor or the like via the cradle.

[0126] Here, the main unit 2 can communicate simultaneously (in other words, in parallel) with multiple left controllers 3. The main unit 2 can also communicate simultaneously (in other words, in parallel) with multiple right controllers 4. Therefore, the user can make inputs to the main unit 2 using multiple left controllers 3 and multiple right controllers 4.

[0127] The main device 2 includes a touch panel controller 86 which is a circuit that controls the touch panel 13. The touch panel controller 86 is connected between the touch panel 13 and the CPU 81. The touch panel controller 86 generates data indicating, for example, the position where a touch input has been performed based on a signal from the touch panel 13, and outputs the data to the CPU 81.

[0128] The display 12 is also connected to the CPU 81. The CPU 81 displays on the display 12 an image generated (for example, by executing the above-mentioned information processing) and / or an image acquired from the outside.

[0129] The main unit 2 includes a codec circuit 87 and speakers (specifically, a left speaker and a right speaker) 88. The codec circuit 87 is connected to the speaker 88 and the audio input / output terminal 25, and is also connected to the CPU 81. The codec circuit 87 is a circuit that controls input and output of audio data to the speaker 88 and the audio input / output terminal 25. That is, when the codec circuit 87 receives audio data from the CPU 81, the codec circuit 87 outputs an audio signal obtained by performing D / A conversion on the audio data to the speaker 88 or the audio input / output terminal 25. As a result, sound is output from the speaker 88 or an audio output unit (e.g., earphones) connected to the audio input / output terminal 25. When the codec circuit 87 receives an audio signal from the audio input / output terminal 25, the codec circuit 87 performs A / D conversion on the audio signal and outputs audio data in a predetermined format to the CPU 81. The volume button 26 is also connected to the CPU 81. The CPU 81 controls the volume output from the speaker 88 or the audio output unit based on an input to the volume button 26.

[0130] The main unit 2 includes a power control unit 97 and a battery 98. The power control unit 97 is connected to the battery 98 and the CPU 81. Although not shown, the power control unit 97 is connected to each unit of the main unit 2 (specifically, each unit that receives power from the battery 98, the left terminal 17, and the right terminal 21). The power control unit 97 controls the power supply from the battery 98 to each unit based on a command from the CPU 81. The power control unit 97 is also connected to the power button 28. The power control unit 97 controls the power supply to each unit based on an input to the power button 28. That is, when an operation to turn off the power is performed on the power button 28, the power control unit 97 stops the power supply to all or part of the units, and when an operation to turn on the power is performed on the power button 28, the power control unit 97 starts the power supply to all or part of the units. The power control unit 97 also outputs information indicating the input to the power button 28 (specifically, information indicating whether the power button 28 is pressed or not) to the CPU 81.

[0131] Furthermore, battery 98 is connected to lower terminal 27. When an external charging device (e.g., a cradle) is connected to lower terminal 27 and power is supplied to main unit 2 via lower terminal 27, battery 98 is charged with the supplied power.

[0132] The main unit 2 also includes a cooling fan 96 for dissipating heat inside the main unit 2. When the cooling fan 96 is operated, air outside the housing 11 is introduced through the intake hole 11d, and air inside the housing 11 is discharged through the exhaust hole 11c, thereby dissipating heat inside the housing 11. The cooling fan 96 is connected to the CPU 81, and the operation of the cooling fan 96 is controlled by the CPU 81. The main unit 2 also includes a temperature sensor 95 for detecting the temperature inside the main unit 2. The temperature sensor 95 is connected to the CPU 81, and the detection result of the temperature sensor 95 is output to the CPU 81. The CPU 81 controls the operation of the cooling fan 96 based on the detection result of the temperature sensor 95.

[0133] Fig. 7 is a block diagram showing an example of the internal configuration of the main unit 2, the left controller 3, and the right controller 4. Note that details of the internal configuration of the main unit 2 are omitted in Fig. 7 because they are shown in Fig. 6.

[0134] The left controller 3 includes a communication control unit 101 that communicates with the main unit 2. As shown in FIG. 7, the communication control unit 101 is connected to each component including the terminal 42. In this embodiment, the communication control unit 101 can communicate with the main unit 2 by both wired communication via the terminal 42 and wireless communication not via the terminal 42. The communication control unit 101 controls the communication method by which the left controller 3 communicates with the main unit 2. That is, when the left controller 3 is attached to the main unit 2, the communication control unit 101 communicates with the main unit 2 via the terminal 42. Also, when the left controller 3 is detached from the main unit 2, the communication control unit 101 performs wireless communication with the main unit 2 (specifically, the controller communication unit 83). The wireless communication between the controller communication unit 83 and the communication control unit 101 is performed according to, for example, the Bluetooth (registered trademark) standard.

[0135] The left controller 3 also includes a memory 102, such as a flash memory. The communication control unit 101 is configured with, for example, a microcomputer (also called a microprocessor), and executes firmware stored in the memory 102 to perform various processes.

[0136] The left controller 3 includes buttons 103 (specifically, buttons 33 to 39, 43, 44, and 46). The left controller 3 also includes an analog stick (referred to as "stick" in FIG. 7) 32. Each button 103 and analog stick 32 repeatedly outputs information relating to operations performed on them to the communication control unit 101 at appropriate timing.

[0137] The left controller 3 includes an acceleration sensor 104. In this embodiment, the acceleration sensor 104 detects the magnitude of linear acceleration along three predetermined axes (for example, the x, y and z axes shown in FIG. 4). The acceleration sensor 104 may detect acceleration in one or two axial directions. The left controller 3 also includes an angular velocity sensor 105. In this embodiment, the angular velocity sensor 105 detects angular velocity around three predetermined axes (for example, the x, y and z axes shown in FIG. 4). The angular velocity sensor 105 may detect angular velocity around one or two axes. The acceleration sensor 104 and the angular velocity sensor 105 are each connected to the communication control unit 101. The detection results of the acceleration sensor 104 and the angular velocity sensor 105 are repeatedly output to the communication control unit 101 at appropriate timing.

[0138] The communication control unit 101 acquires information related to the input (specifically, information related to the operation, or the detection results by the sensors) from each input unit (specifically, each button 103, analog stick 32, each sensor 104 and 105). The communication control unit 101 transmits operation data including the acquired information (or information obtained by performing a specified process on the acquired information) to the main unit 2. The operation data is repeatedly transmitted once every specified time. The interval at which the information related to the input is transmitted to the main unit 2 may or may not be the same for each input unit.

[0139] By transmitting the above operation data to the main unit 2, the main unit 2 can obtain the input performed on the left controller 3. That is, the main unit 2 can determine the operations on the buttons 103 and the analog stick 32 based on the operation data. In addition, the main unit 2 can calculate information regarding the movement and / or attitude of the left controller 3 based on the operation data (specifically, the detection results of the acceleration sensor 104 and the angular velocity sensor 105).

[0140] The left controller 3 includes a vibrator 107 for notifying the user by vibration. In this embodiment, the vibrator 107 is controlled by a command from the main unit 2. That is, when the communication control unit 101 receives the command from the main unit 2, it drives the vibrator 107 according to the command. Here, the left controller 3 includes an amplifier 106. When the communication control unit 101 receives the command, it outputs a control signal according to the command to the amplifier 106. The amplifier 106 amplifies the control signal from the communication control unit 101, generates a drive signal for driving the vibrator 107, and provides the drive signal to the vibrator 107. This causes the vibrator 107 to operate.

[0141] The left controller 3 is equipped with a power supply unit 108. In this embodiment, the power supply unit 108 has a battery and a power control circuit. Although not shown, the power control circuit is connected to the battery, and is also connected to each part of the left controller 3 (specifically, each part that receives power from the battery). The power control circuit controls the power supply from the battery to each of the above-mentioned parts. In addition, the battery is connected to a terminal 42. In this embodiment, when the left controller 3 is attached to the main unit 2, the battery is charged by power supplied from the main unit 2 via the terminal 42 under predetermined conditions.

[0142] As shown in FIG. 7, the right controller 4 includes a communication control unit 111 that communicates with the main unit 2. The right controller 4 also includes a memory 112 that is connected to the communication control unit 111. The communication control unit 111 is connected to each component including the terminal 64. The communication control unit 111 and the memory 112 have the same functions as the communication control unit 101 and the memory 102 of the left controller 3. Therefore, the communication control unit 111 can communicate with the main unit 2 by both wired communication via the terminal 64 and wireless communication (specifically, communication in accordance with the Bluetooth (registered trademark) standard) that does not go through the terminal 64, and controls the method of communication that the right controller 4 uses with the main unit 2.

[0143] The right controller 4 has input sections similar to those of the left controller 3 (specifically, the buttons 113, the analog stick 52, the acceleration sensor 114, and the angular velocity sensor 115). Each of these input sections has the same function as that of the left controller 3, and operates in the same manner.

[0144] The right controller 4 also includes a transducer 117 and an amplifier 116. The transducer 117 and the amplifier 116 operate in the same manner as the transducer 107 and the amplifier 106 of the left controller 3. That is, the communication control unit 111 operates the transducer 117 using the amplifier 116 in accordance with a command from the main unit 2.

[0145] The right controller 4 is equipped with a power supply unit 118. The power supply unit 118 has the same functions as the power supply unit 108 of the left controller 3, and operates in the same manner. That is, the power supply unit 118 controls the power supply to each unit that receives power from the battery. In addition, when the right controller 4 is attached to the main unit 2, the battery is charged by power supplied from the main unit 2 via the terminal 64 under certain conditions.

[0146] The right controller 4 includes an NFC communication unit 122 that performs short-distance wireless communication based on the NFC standard. The NFC communication unit 122 has a function of a so-called NFC reader / writer. Here, in this specification, short-distance wireless communication includes a communication method in which an electromotive force is generated in another device (here, a device in close proximity to the antenna 122a) by radio waves (for example, by electromagnetic induction) from one device (here, the right controller 4). The other device can operate by the generated electromotive force, and may or may not have a power source. The NFC communication unit 122 can communicate with the communication target when the right controller 4 (antenna 122a) and the communication target approach each other (typically, when the distance between them is less than 10 centimeters). The communication target is any device that can perform short-distance wireless communication with the NFC communication unit 122, such as an NFC tag or a storage medium having the function of an NFC tag. However, the communication target may be another device having an NFC card emulation function.

[0147] The right controller 4 also includes an infrared imaging unit 123. The infrared imaging unit 123 has an infrared camera that captures images of the surroundings of the right controller 4. The infrared imaging unit 123 may capture images using ambient light, but in this embodiment, it has an infrared light emitting unit 124 that radiates infrared rays. The infrared light emitting unit 124 radiates infrared rays, for example, in synchronization with the timing at which the infrared camera captures an image.

[0148] The right controller 4 includes a processing unit 121. The processing unit 121 is connected to the communication control unit 111 and is also connected to the NFC communication unit 122. The processing unit 121 executes management processing for the NFC communication unit 122 in response to a command from the main unit 2. For example, the processing unit 121 controls the operation of the NFC communication unit 122 in response to a command from the main unit 2. The processing unit 121 also controls the start-up of the NFC communication unit 122, and controls the operation (specifically, reading and writing, etc.) of the NFC communication unit 122 with respect to a communication target (e.g., an NFC tag). The processing unit 121 also receives information to be transmitted to the communication target from the main unit 2 via the communication control unit 111 and passes it to the NFC communication unit 122, and obtains information received from the communication target from the NFC communication unit 122 and transmits it to the main unit 2 via the communication control unit 111.

[0149] The processing unit 121 also includes a CPU, a memory, etc., and executes management processing for the infrared imaging unit 123 in response to a command from the main unit 2 based on a predetermined program (e.g., an application program for performing image processing or various calculations) stored in a storage device (e.g., a non-volatile memory or a hard disk, etc.) not shown in the right controller 4. For example, the processing unit 121 causes the infrared imaging unit 123 to perform an imaging operation, acquires and / or calculates information based on the imaging result (e.g., information on the captured image, or information calculated from the information, etc.), and transmits the information to the main unit 2 via the communication control unit 111. The processing unit 121 also executes management processing for the infrared emission unit 124 in response to a command from the main unit 2.

[0150] Next, a steering wheel type attachment 200, which is an example of an attachment device, will be described with reference to Figs. 8 to 11. Fig. 8 is a perspective view showing an example of the appearance of the steering wheel type attachment 200. Fig. 9 is a six-sided view showing an example of the appearance of the steering wheel type attachment 200. Fig. 9 (a) is a front view of the steering wheel type attachment 200, (b) is a top view of the steering wheel type attachment 200, (c) is a right side view of the steering wheel type attachment 200, (d) is a bottom view of the steering wheel type attachment 200, (e) is a left side view of the steering wheel type attachment 200, and (f) is a rear view of the steering wheel type attachment 200. Fig. 10 is a cross-sectional view showing an example of the configuration of the steering wheel type attachment 200 as viewed from the cross section AA. Fig. 11 is a cross-sectional view showing an example of the configuration of the steering wheel type attachment 200 as viewed from the cross section BB.

[0151] 8 to 11, a steering wheel type attachment 200 has at least a main body gripping portion 201, a movable portion 202, and a biasing portion 203. In FIG.

[0152] The main body gripping part 201 has a steering wheel type rim part (also called a steering part or a wheel part) with a periphery formed in a substantially circular shape. In the example shown in FIG. 8 and FIG. 9, the main body gripping part 201 is provided with a circular ring-shaped rim part. The shape of the rim part does not have to be circular, and may be any shape that allows a user to grip and steer, such as a shape with a part of the ring removed, a part of the ring deformed, an ellipse, a drop handle type shape, or a shape with multiple protruding parts provided on the outer periphery. The cross-sectional shape of the rim part does not have to be circular, and may be other cross-sectional shapes such as an ellipse, an oval shape, a polygon, a polygon with rounded corners, a deformed circle, etc. The main body gripping part 201 has a fixing part 201a formed in a concave shape near the center of the rim part (for example, near the center of the substantially circular shape). The fixed part 201a is formed in a concave shape that can engage with the left controller 3 or the right controller 4 in the lateral direction, and a plurality of biasing parts 203 (three biasing parts 203a, 203b, and 203c in this embodiment) are provided on the upper and lower walls of the concave shape. In addition, a pair of movable parts 202 are provided on the upper wall of the concave shape of the fixed part 201a.

[0153] The main body gripping part 201 is formed by joining a front part 201f, which is the front side part where the fixed part 201a is formed, and a rear part 201r, which is the rear side part (the part where the operation parts 202Le and 202Re of the movable part 202 described later are provided). Here, as is clear from FIG. 11 and the like, the joint surface between the front part 201f and the rear part 201r is provided approximately in the vicinity of the center of the front side and the rear side on the outer periphery of the rim part, but is provided on the front side of the center of the front side and the rear side on the inner periphery of the rim part. By forming the joint surface between the front part 201f and the rear part 201r in this way, when the user grips the rim part, the user is less likely to come into contact with the joint surface provided on the inner periphery of the rim part, and the feel during operation can be improved. In addition, the front side of the steering wheel type attachment 200 on which the fixed part 201a is formed is the front side of the user who operates the steering wheel type attachment 200, and the rear side on which the operation parts 202Le and 202Re of the movable part 202 are provided is the rear side as seen from the user. Therefore, in the following description, in the steering wheel type attachment 200, the side that faces the user when the user holds it for operation may be described as the "front" and the side behind the "front" may be described as the "rear". In addition, from another perspective, the side of the steering wheel type attachment 200 on which the fixed part 201a is formed may be considered as the "front", and the side on which the operation parts 202Le and 202Re of the movable part 202 are provided may be considered as the "rear".

[0154] As shown in FIG. 10, a pair of left and right recesses 201aL and 201aR are formed on the bottom surface (surface on the rear side) of the fixed part 201a of the main body grip part 201. As will be clear from the following description, the recess 201aL engages with a rear protrusion formed by the ZL button 39 and the like provided on the rear surface of the left controller 3 when the left controller 3 is attached to the fixed part 201a. In addition, the recess 201aR engages with a rear protrusion formed by the ZR button 61 and the like provided on the rear surface of the right controller 4 when the right controller 4 is attached to the fixed part 201a. Here, the engagement between the rear protrusion and the recess 201aL or 201aR may be in a state where the entire parts are not in contact with each other, or the parts are not in contact with each other. In addition, a removal window 201b is formed by cutting out a central part of the lower wall of the fixed part 201a of the main body grip part 201 in an arc shape.

[0155] The movable part 202 is composed of a pair of left movable part 202L and right movable part 202R. The left movable part 202L has a left operation part 202Le, a left button pressing part 202Lw, and a left shaft part 202Lp (see FIG. 15). The left operation part 202Le protrudes from the left side of the back surface of the main body grip part 201 to the outside, and is provided so as to be pressed downward by the index finger, middle finger, etc. of the left hand of the user who is gripping the steering wheel type attachment 200. The left button pressing part 202Lw is provided so as to protrude from the left upper wall of the fixing part 201a of the main body grip part 201, and can also function as a left protruding part. Here, "protruding" includes not only a mode in which it protrudes from the left upper wall only when it moves in response to a user operation, but also a mode in which it is in a protruding state from the left upper wall before the user operation is performed, and moves in a direction further away from the left upper wall in response to the user operation. When the left operation part 202Le is pressed down, the left movable part 202L rotates about the left shaft part 202Lp, causing the left button pressing part 202Lw to protrude into the fixed part 201a. When the left operation part 202Le is not pressed down, the left movable part 202L is biased in the opposite direction to rotate about the left shaft part 202Lp, causing the left button pressing part 202Lw to retreat from within the fixed part 201a. The position in the fixed part 201a where the left button pressing part 202Lw is provided will be described later.

[0156] The right movable part 202R has a right operation part 202Re, a right button pressing part 202Rw, and a right shaft part 202Rp (see Figs. 15 to 17). The right operation part 202Re protrudes from the right side of the back surface of the main body grip part 201 to the outside, and is provided so as to be pressable downward by the index finger, middle finger, or the like of the right hand of the user holding the steering wheel type attachment 200. The right button pressing part 202Rw is provided so as to be protrudible from the right upper wall of the fixing part 201a of the main body grip part 201, and can also function as a right protruding part. Here, being protrudible includes not only a mode in which it protrudes from the right upper wall only when it moves in response to a user operation, but also a mode in which it protrudes from the right upper wall before the user operation is performed, and moves in a direction further away from the right upper wall in response to the user operation. When the right operation part 202Re is pressed, the right movable part 202R rotates about the right shaft part 202Rp, and the right button pressing part 202Rw protrudes into the fixed part 201a. When the right operation part 202Re is not pressed, the movable part 202R is biased in the opposite direction to rotate about the right shaft part 202Rp, and the right button pressing part 202Rw retreats from the fixed part 201a. The position in the fixed part 201a where the right button pressing part 202Rw is provided will be described later.

[0157] As shown in FIG. 9, the left operating part 202Le of the left movable part 202L, the right operating part 202Re of the right movable part 202R, and the rear part 201r of the main body grip part 201 are arranged on the rear side of the rim part in the steering wheel type attachment 200. Here, of the three components arranged on the rear side, the rear part 201r of the main body grip part 201 is provided at the rear end of the steering wheel type attachment 200. Specifically, as shown in FIG. 9, the rear part 201r is formed in a state where it protrudes further rearward by a distance X from the rearmost end of the left operating part 202Le and the right operating part 202Re. In this way, by arranging a part of the main body grip part 201 at the rear end of the steering wheel type attachment 200, the part can be made to function as a guard part for the movable part 202. For example, when the steering wheel type attachment 200 is placed with its back side facing down on a flat surface, the guard portion can mitigate unexpected impact or pressure that may be applied to the movable part 202 from the surface on which it is placed.

[0158] The biasing unit 203 is composed of, for example, three biasing units 203a, 203b, and 203c, each of which is composed of an elastic member (for example, a rubber member such as silicone rubber) that holds the left controller 3 or the right controller 4 attached to the fixed unit 201a so as not to come off the fixed unit 201a. As shown in FIG. 9, the biasing unit 203a is fixed to the center of the upper wall of the fixed unit 201a of the main body gripping unit 201 in a state in which it protrudes downward from the upper wall. The biasing unit 203b is fixed to the left lower wall of the fixed unit 201a of the main body gripping unit 201, which is directly below or outside (left side) the left button pressing area 202Lw, in a state in which it protrudes upward from the lower wall. The biasing unit 203c is fixed to the right lower wall of the fixed unit 201a of the main body gripping unit 201, which is directly below or outside (right side) the right button pressing area 202Rw, in a state in which it protrudes upward from the lower wall.

[0159] The elastic member constituting the biasing parts 203a, 203b, and 203c may be a spring member (such as a leaf spring or a coil spring) or a foam member (such as a sponge). The biasing parts 203a, 203b, and 203c may not be made of an elastic member, and may be made of a weakly adhesive adhesive tape or a hook-and-loop fastener. The biasing parts 203a, 203b, and 203c may be integrally formed with the wall surface of the fixed part 201a. The biasing parts 203a, 203b, and 203c may not protrude from the wall surface of the fixed part 201a, and may be made of a recess formed in the wall surface. For example, it is also possible to hold the left controller 3 or right controller 4 attached to the fixed part 201a so that it does not come off by engaging the recess formed in the wall surface with the side surface of the left controller 3 or the right controller 4.

[0160] Next, a state in which the left controller 3 or the right controller 4 is attached to the steering wheel type attachment 200 will be described with reference to Figs. 12 to 14. Fig. 12 is an explanatory diagram showing an example of a state in which the left controller 3 or the right controller 4 is attached to the steering wheel type attachment 200. Fig. 13 is a front view showing an example of a state in which the left controller 3 is attached to the steering wheel type attachment 200. Fig. 14 is a front view showing an example of a state in which the right controller 4 is attached to the steering wheel type attachment 200.

[0161] 12, either the left controller 3 or the right controller 4 can be detachably attached to the steering wheel type attachment 200, and either one can be attached. For example, when attaching the left controller 3 to the steering wheel type attachment 200, the housing 31 of the left controller 3 is engaged with the fixing part 201a so that the right side surface (the side surface formed on the x-axis negative side in FIG. 4) of the left controller 3 that is joined to the main unit 2 is aligned with the upper wall of the fixing part 201a of the main body grip part 201, and the back surface of the left controller 3 (the back surface formed on the z-axis positive side in FIG. 4) abuts against the bottom surface of the fixing part 201a. Furthermore, when attaching the right controller 4 to the steering wheel-type attachment 200, the housing 51 of the right controller 4 is engaged with the fixing portion 201a so that the left side surface (the side surface formed on the positive x-axis side in FIG. 5) of the right controller 4 that is joined to the main unit 2 is aligned with the upper wall of the fixing portion 201a of the main body gripping portion 201, and the back surface of the right controller 4 (the back surface formed on the positive z-axis side in FIG. 5) abuts against the bottom surface of the fixing portion 201a.

[0162] As shown in Fig. 13, when the left controller 3 is attached to the steering wheel type attachment 200, the left controller 3 is engaged in the fixing part 201a so that the bottom surface of the fixing part 201a of the steering wheel type attachment 200 comes into contact with the back surface of the left controller 3. In this case, a recessed part 201aL (see Fig. 10) formed on the left side of the bottom surface of the fixing part 201a is engaged with a back surface protrusion (see Fig. 4) formed by the ZL button 39 or the like provided on the back surface of the left controller 3. In addition, a part near the center of the right side surface of the left controller 3 (the side surface formed on the negative x-axis direction side in Fig. 4, which faces upward when attached to the fixing part 201a) is supported by the biasing part 203a. A portion of the left side surface of the left controller 3 (the side surface formed on the positive x-axis direction in FIG. 4, which faces downward when attached to the fixed part 201a) near a position facing the second L button 43 is supported by the biasing part 203b. A portion of the left side surface of the left controller 3 near a position facing the second R button 44 is supported by the biasing part 203c. In this way, when the left controller 3 is attached to the fixed part 201a, both side surfaces of the left controller 3 (both side surfaces which face up and down when attached to the fixed part 201a) are supported by the three biasing parts 203a, 203b, and 203c, respectively.

[0163] Also, the width of the fixed part 201a is formed to be larger than the width of the left controller 3 (the length in the y-axis direction in FIG. 4) by a length S1. Therefore, the left controller 3 can be attached to the fixed part 201a in a state where it abuts against the left wall of the fixed part 201a, or it can be attached to the fixed part 201a in a state where it abuts against the right wall of the fixed part 201a, or it can be attached to the fixed part 201a in a state where it does not abut against either the left or right wall of the fixed part 201a. However, when the left controller 3 is attached to the fixed part 201a in this embodiment, the left and right positions of the mark ML marked on the main body grip part 201 and the - button 47 of the left controller 3 are aligned, and the housing 31 of the left controller 3 is engaged with the fixed part 201a so that the right side surface of the left controller 3 (the lower side surface formed on the y-axis negative direction side in FIG. 4) abuts against the right wall of the fixed part 201a. By positioning the left controller 3 in the fixed part 201a in this way, the left and right positions of the second L button 43 and the left button pressing part 202Lw of the left movable part 202L match, and the left and right positions of the second R button 44 and the right button pressing part 202Rw of the right movable part 202R match. Therefore, when the left button pressing part 202Lw protrudes into the fixed part 201a with the left controller 3 attached in the fixed part 201a at the above position, the left button pressing part 202Lw presses the second L button 43. Also, when the right button pressing part 202Rw protrudes into the fixed part 201a with the left controller 3 attached in the fixed part 201a at the above position, the right button pressing part 202Rw presses the second R button 44. In other words, by attaching the left controller 3 to the fixed part 201a so that it matches the position of the sign ML indicated on the main body grip part 201, the user can easily recognize the direction in which to attach the left controller 3 to the steering wheel type attachment 200, and can also grasp the exact position in which to attach it within the fixed part 201a.

[0164] As described above, the biasing portion 203b is provided at a position directly below or outside the left button pressing portion 202Lw, and the biasing portion 203c is provided at a position directly below or outside the right button pressing portion 202Rw. In other words, when the second L button 43 is pressed by the left button pressing portion 202Lw protruding into the fixed portion 201a, the biasing portion 203b supports the second L button 43 at a position slightly to the left of directly below the left button 43, or the biasing portions 203b and 203c support the second L button 43 at both positions below the left button 43. This makes it possible to stably press the second L button 43. In addition, when the second R button 44 is pressed down by the right button pressing portion 202Rw protruding into the fixed portion 201a, the second R button 44 is supported at a position slightly to the right of directly below it by the biasing portion 203c, or is supported at positions on both sides below it by the biasing portion 203b and the biasing portion 203c, so that the second R button 44 can be pressed down stably.

[0165] Moreover, the width of the left button pressing portion 202Lw in the front-to-rear direction (i.e., the direction from the front to the back) is formed to be larger than the width of the second L button 43 in that direction (the z-axis direction shown in FIG. 4). Moreover, the width of the right button pressing portion 202Rw in the front-to-rear direction is formed to be larger than the width of the second R button 44 in that direction. As a result, even if the mounting depth of the left controller 3 attached to the fixing portion 201a varies in the front-to-rear direction, this can be absorbed by the relatively large widths of the left button pressing portion 202Lw and the right button pressing portion 202Rw in the front-to-rear direction, so that the second L button 43 and the second R button 44 can be reliably pressed by the left button pressing portion 202Lw and the right button pressing portion 202Rw. In addition, a part of the left button pressing area 202Lw or the right button pressing area 202Rw comes into contact with a part of the slider 40 of the left controller 3 located around the second L button 43 and the second R button 44, thereby restricting the second L button 43 and the second R button 44 from being pressed excessively, thereby preventing excessive load on the second L button 43 and the second R button 44.

[0166] As shown in FIG. 14, when the right controller 4 is attached to the steering wheel type attachment 200, the right controller 4 is engaged in the fixing part 201a so that the bottom surface of the fixing part 201a of the steering wheel type attachment 200 comes into contact with the back surface of the right controller 4. In this case, the recessed part 201aR (see FIG. 10) formed on the right side of the bottom surface of the fixing part 201a is engaged with the back surface protrusion (see FIG. 5) formed by the ZR button 61 and the like provided on the back surface of the right controller 4. In addition, a part near the center of the left side surface of the right controller 4 (the side surface formed on the x-axis positive direction side in FIG. 5, which faces upward when attached to the fixing part 201a) is supported by the biasing part 203a. A portion of the right side surface of the right controller 4 (the side surface formed on the negative x-axis direction in FIG. 5, which faces downward when attached to the fixed part 201a) near a position facing the second L button 65 is supported by the biasing part 203b. A portion of the right side surface of the right controller 4 near a position facing the second R button 66 is supported by the biasing part 203c. In this way, when the right controller 4 is attached to the fixed part 201a, both side surfaces of the right controller 4 (both side surfaces which face up and down when attached to the fixed part 201a) are supported by the three biasing parts 203a, 203b, and 203c, respectively.

[0167] The width of the fixed part 201a is greater than the width of the right controller 4 (the length in the y-axis direction in FIG. 5) by a length S2. Therefore, the right controller 4 can also be attached to the fixed part 201a in a state where it abuts against the left wall of the fixed part 201a, or in a state where it abuts against the right wall of the fixed part 201a, or in a state where it does not abut against either the left or right wall of the fixed part 201a. However, when the right controller 4 is attached to the fixed part 201a in this embodiment, the left and right positions of the mark MR written on the main body grip part 201 and the + button 57 of the right controller 4 are matched, and the housing 51 of the right controller 4 is engaged with the fixed part 201a so that the left side surface of the right controller 4 (the lower side surface formed on the negative y-axis direction in FIG. 5) abuts against the left wall of the fixed part 201a. By positioning the right controller 4 in the fixed part 201a in this way, the left and right positions of the second L button 65 and the left button pressing part 202Lw of the left movable part 202L match, and the left and right positions of the second R button 66 and the right button pressing part 202Rw of the right movable part 202R match. Therefore, when the left button pressing part 202Lw protrudes into the fixed part 201a with the right controller 4 attached in the fixed part 201a at the above position, the left button pressing part 202Lw presses the second L button 65. Also, when the right button pressing part 202Rw protrudes into the fixed part 201a with the right controller 4 attached in the fixed part 201a at the above position, the right button pressing part 202Rw presses the second R button 66. In other words, by attaching the right controller 4 to the fixed part 201a so that it matches the position of the sign MR indicated on the main body gripping part 201, the user can easily recognize the direction in which to attach the right controller 4 to the steering wheel type attachment 200, and can also grasp the exact position in which to attach it within the fixed part 201a.

[0168] Here, as described above, the biasing portion 203b is provided at a position that is outward (left side) from directly below the left button pressing portion 202Lw, and the biasing portion 203c is provided at a position that is outward (right side) from directly below the right button pressing portion 202Rw. In other words, when the second L button 65 is pressed by the left button pressing portion 202Lw protruding into the fixed portion 201a, the biasing portion 203b and the biasing portion 203c support both positions below the button 65, so that the second L button 65 can be pressed stably. Also, when the right button pressing portion 202Rw protruding into the fixed portion 201a, the biasing portion 203b and the biasing portion 203c support both positions below the button 65, so that the second R button 66 can be pressed stably.

[0169] As described above, the biasing portion 203b may be provided at a position directly below the left button pressing portion 202Lw, and the biasing portion 203c may be provided at a position directly below the right button pressing portion 202Rw. In other words, when the second L button 65 is pressed by the left button pressing portion 202Lw protruding into the fixed portion 201a, the biasing portion 203b supports the position directly below the left button pressing portion 202Lw, so that the second L button 65 can be pressed stably in this case as well. Also, when the second R button 66 is pressed by the right button pressing portion 202Rw protruding into the fixed portion 201a, the biasing portion 203b supports the position directly below the right button pressing portion 202Rw, so that the second R button 66 can be pressed stably in this case as well.

[0170] Also, the width of the left button pressing portion 202Lw in the front-to-rear direction (i.e., the direction from the front to the back) is formed to be larger than the width of the second L button 65 in that direction (the z-axis direction shown in FIG. 4). Also, the width of the right button pressing portion 202Rw in the front-to-rear direction is formed to be larger than the width of the second R button 66 in that direction. As a result, even if the mounting depth of the right controller 4 attached to the fixing portion 201a varies in the front-to-rear direction, this can be absorbed by the relatively large widths in the front-to-rear direction of the left button pressing portion 202Lw and the right button pressing portion 202Rw, so that the second L button 65 and the second R button 66 can also be reliably pressed by the left button pressing portion 202Lw and the right button pressing portion 202Rw. In addition, a part of the left button pressing area 202Lw or the right button pressing area 202Rw comes into contact with a part of the slider 40 of the left controller 3 located around the second L button 65 and the second R button 66, thereby restricting the second L button 65 and the second R button 66 from being pressed excessively, thereby preventing excessive load on the second L button 65 and the second R button 66.

[0171] 13 and 14, the length T1 from the left side surface (i.e., the upper side surface formed on the y-axis positive side in FIG. 4) to the second L button 43 when the left controller 3 is attached to the fixed part 201a is different from the length T3 from the left side surface (i.e., the lower side surface formed on the y-axis negative side in FIG. 5) to the second L button 65 when the right controller 4 is attached to the fixed part 201a. Therefore, when the left controller 3 and the right controller 4 are attached at the same position in the fixed part 201a, the position where the second L button 43 is disposed and the position where the second L button 65 is disposed are different in the fixed part 201a, and it becomes impossible to press both the second L button 43 and the second L button 65 using one left button pressing part 202Lw. However, by attaching the left controller 3 and the right controller 4 in the fixed part 201a with a shift to the left or right by the length S1, the position in the fixed part 201a where the second L button 43 is arranged and the position in which the second L button 65 is arranged become the same, and it is possible to press the second L button 43 and the second L button 65 using one left button pressing part 202Lw. In other words, the difference S1 between the width of the fixed part 201a and the width of the left controller 3 and the right controller 4 (the length in the y-axis direction in Figures 4 and 5) may be set to the difference between the above length T3 and the above length T1.

[0172] In addition, the length T2 from the right side surface (i.e., the lower side surface formed on the negative y-axis side in FIG. 4) to the second R button 44 when the left controller 3 is attached to the fixed part 201a and the length T4 from the right side surface (i.e., the upper side surface formed on the positive y-axis side in FIG. 5) to the second R button 66 when the right controller 4 is attached to the fixed part 201a are different lengths. Therefore, when the left controller 3 and the right controller 4 are attached at the same position in the fixed part 201a, the position where the second R button 44 is disposed and the position where the second R button 66 is disposed are different in the fixed part 201a, and it becomes impossible to press both the second R button 44 and the second R button 66 using one right button pressing part 202Rw. However, by attaching the left controller 3 and the right controller 4 in the fixed part 201a with a shift in the left and right direction by the length S1, the position where the second R button 44 is arranged in the fixed part 201a and the position where the second L button 65 is arranged become the same, and the second R button 44 and the second R button 66 can be pressed using one right button pressing part 202Rw. In other words, by configuring the above-mentioned length T1 and the above-mentioned length T4 to be the same length, and the above-mentioned length T2 and the above-mentioned length T3 to be the same length, due to the difference S1 between the width of the fixed part 201a and the width of the left controller 3 and the right controller 4 (the length in the y-axis direction in Figures 4 and 5), it becomes possible to simultaneously press the second R button 44 and the second R button 66 using one right button pressing part 202Rw.

[0173] When removing the left controller 3 or the right controller 4 attached to the steering wheel type attachment 200, the removal window 201b formed in the lower wall of the fixing part 201a is used. As described above, the removal window 201b is formed by cutting out a central part of the lower wall of the fixing part 201a in an arc shape. This removal window 201b exposes a part of the side of the left controller 3 or the right controller 4 attached to the steering wheel type attachment 200 facing downward (the side of the left controller 3 formed on the positive x-axis side in FIG. 4 and the side of the right controller 4 formed on the negative x-axis side in FIG. 5) to the outside of the fixing part 201a. Therefore, with the entire steering wheel type attachment 200 fixed, the user can easily remove the left controller 3 or the right controller 4 attached to the fixing part 201a by hooking their fingers on the side of the left controller 3 or the right controller 4 exposed from the removal window 201b and pulling it toward themselves. The removal window 201b may be formed in a wall other than the bottom wall of the fixed portion 201a, or may be formed in a plurality of places in the bottom wall and / or the other wall of the fixed portion 201a.

[0174] Next, the operation and structure of the movable part 202 will be described with reference to Fig. 15 to Fig. 17. Fig. 15 is an internal structural diagram showing an example of the operation of the left movable part 202L and the right movable part 202R in the steering wheel type attachment 200. Fig. 16 is a perspective view showing an example of the appearance of the right movable part 202R. Fig. 17 is a three-sided view showing an example of the appearance of the right movable part 202R.

[0175] In FIG. 15, the left movable part 202L is provided on the rear part 201r of the main body grip part 201 so as to be rotatable around the left shaft part 202Lp. When the left operation part 202Le is pressed downward, the left movable part 202L rotates counterclockwise around the left shaft part 202Lp, and the left button pressing part 202Lw also rotates in the same downward direction. The left movable part 202L is biased by the spring 204L in the opposite direction to the rotation direction caused by the above pressing (i.e., clockwise), and is supported so that the left operation part 202Le is disposed at a predetermined operation waiting position (for example, a position where the left operation part 202Le is substantially horizontal) when the left operation part 202Le is not pressed. Note that the example shown in FIG. 15 shows a state in which the left movable part 202L is disposed at the above waiting position.

[0176] In FIG. 15, the right movable part 202R is provided on the rear part 201r of the main body grip part 201 so as to be rotatable around the right shaft part 202Rp. When the right operation part 202Re is pressed downward, the right movable part 202R rotates clockwise around the right shaft part 202Rp, and the right button pressing part 202Rw also rotates in the same downward direction. The right movable part 202R is biased by the spring 204R in the opposite direction to the rotation direction caused by the above pressing (i.e., counterclockwise), and is supported so that the right operation part 202Re is located at a predetermined operation waiting position (for example, a position where the right operation part 202Re is approximately horizontal) when the right operation part 202Re is not pressed. Note that the example shown in FIG. 15 shows a state in which the right movable part 202R is pressed and the right button pressing part 202Rw protrudes into the fixed part 201a.

[0177] For example, the left movable portion 202L and the right movable portion 202R are configured to have a symmetrical shape. In the following description, the structure of the movable portion 202 will be described using the right movable portion 202R as a representative example.

[0178] 16 and 17, the right movable part 202R generally has a right operation part 202Re, a right button pressing part 202Rw, an arm part 202Ra, and a right shaft part 202Rp, and is formed, for example, by integral molding. The right shaft part 202Rp is rotatably supported by the main body grip part 201 with the front-rear direction as the axial direction. The right operation part 202Re and the right button pressing part 202Rw are both provided on the right side of the right shaft part 202Rp, and are fixed to the right shaft part 202Rp via the arm part 202Ra that connects the right shaft part 202Rp and the right operation part 202Re. Also, the distance in the direction perpendicular to the axial direction from the right operation part 202Re to the right shaft part 202Rp (the length of the arm part 202Ra of the right operation part 202Re) is longer than the distance in the direction perpendicular to the axial direction from the right button pressing part 202Rw to the right shaft part 202Rp (the length of the arm part 202Ra of the right button pressing part 202Rw). Therefore, when the right operation part 202Re is pressed, the right button pressing part 202Rw also rotates in the same direction. Also, the amount of movement of the right button pressing part 202Rw that moves due to the above rotation is smaller than the amount of movement when the right operation part 202Re is pressed. Here, the amount of movement is the amount of movement of the right button pressing part 202Rw and the right operation part 202Re that each move due to the above rotation, and indicates the length of the arc that is described when the right movable part 202R rotates around the right shaft part 202Rp.

[0179] In this way, the right movable part 202R functions as a lever with the right shaft part 202Rp as the fulcrum, the right operation part 202Re as the force point, and the right button pressing part 202Rw as the point of action. Specifically, the right movable part 202R functions as a lever with the fulcrum (right shaft part 202Rp) as the center, in which the point of action moves a shorter distance (the right button pressing part 202Rw moves protrudingly) than the force point in the same direction as the force point in response to the movement of the force point (the movement of the right operation part 202Re by the pressing operation). Therefore, when the right operation part 202Re is pressed, the second R button 44 or the second R button 66 is pressed with a smaller movement amount than the amount of movement of the pressing operation, and it becomes possible to press the operation buttons of the attached left controller 3 or right controller 4 with a smaller force, and it becomes possible to operate the operation buttons with a delicate amount of force.

[0180] As described above, the left movable part 202L is configured in a symmetrical shape with the right movable part 202R. Therefore, the left movable part 202L also functions as a lever with the left shaft part 202Lp as a fulcrum, the left operation part 202Le as a force point, and the left button pressing part 202Lw as a point of action. That is, the left movable part 202L functions as a lever with the fulcrum (left shaft part 202Lp) as the center, in which the force point moves in the same direction as the force point and a shorter distance than the force point (the left button pressing part 202Lw moves forward) in response to the movement of the force point (the movement of the left operation part 202Le by the pressing operation). Therefore, when the left operation part 202Le is pressed, the second L button 43 or the second L button 65 is pressed with a smaller movement amount than the movement amount of the pressing operation, and it becomes possible to press the operation button of the attached left controller 3 or left controller 4 with a smaller force, and it becomes possible to operate the operation button with a delicate force adjustment.

[0181] The above-mentioned "amount of movement" is a concept that includes the amount of keystroke of the right operation portion 202Re (and the right button press portion 202Rw) and the left operation portion 202Le (and the left button press portion 202Lw), the amount of keystroke of the right button press portion 202Rw pressing the second R button 44 or the second R button 66, and the amount of keystroke of the left button press portion 202Lw pressing the second L button 43 or the second L button 65.

[0182] The arm 202Ra that connects the right shaft 202Rp and the right operation part 202Re and that connects the right shaft 202Rp and the right button pressing part 202Rw may be one arm as shown in Fig. 16 and Fig. 17, but these arms may be provided as separate bodies. That is, if the separate arms share the right shaft 202Rp and the right operation part 202Re and the right button pressing part 202Rw move in conjunction with each other, the separate arms may be regarded as one arm that connects the right operation part 202Re and the right button pressing part 202Rw. The right shaft 202Rp may be integral with or separate from the right movable part 202R, and may be structured so that the arm of the right operation part 202Re and the arm of the right button pressing part 202Rw rotate around the fixed right shaft 202Rp.

[0183] In addition, the end of the lower surface of the right button pressing portion 202Rw that abuts against the second R button 44 or the second R button 66 has a chamfered shape. Specifically, a curved surface with a predetermined curvature is generated at the end of the lower surface of the right button pressing portion 202Rw. Among the ends of the lower surface, the curvature R1 of the end curved surface closest to the right shaft portion 202Rp is formed relatively larger than the curvature R2 of the end curved surface farthest from the right shaft portion 202Rp (for example, R1=1.5R, R2=0.5R). In this way, by forming a relatively large R shape (a curved surface with curvature R1) at the end closest to the right shaft portion 202Rp, when protruding toward the fixed portion 201a, the flat portion of the right button pressing portion 202Rw is likely to come into contact with the second R button 44 or the second R button 66 first, and it is possible to prevent a deterioration in the operability caused by the end first coming into contact with the second R button 44 or the second R button 66. Also, by forming a relatively large R shape at the end closest to the right shaft portion 202Rp, it is possible to reduce the excessive load that the right button pressing portion 202Rw applies to the second R button 44 or the second R button 66.

[0184] The chamfered shape of the end of the lower surface of the right button pressing portion 202Rw does not have to be a curved surface, and may be any shape that does not form a right angle. For example, the end of the lower surface of the right button pressing portion 202Rw may be beveled, or may be rounded with multiple curvatures. Regardless of the chamfered shape, the end of the lower surface of the right button pressing portion 202Rw closest to the right shaft portion 202Rp is formed to be chamfered more than the end farthest from the right shaft portion 202Rp.

[0185] As described above, the left movable part 202L is configured with a shape symmetrical to the right movable part 202R, and in the above description, the structure of the movable part 202 is described using the right movable part 202R as a representative, but the end of the lower surface of the left button pressing part 202Lw is also formed with a chamfered shape similar to that of the right button pressing part 202Rw. That is, a curved surface with a predetermined curvature is generated at the end of the lower surface of the left button pressing part 202Lw that abuts against the second L button 43 or the second L button 65. Then, of the ends of the lower surface, the curvature R3 of the end curved surface closest to the left shaft part 202Lp is formed relatively larger than the curvature R4 of the end curved surface farthest from the left shaft part 202Lp, similar to the curvature R1 (for example, R3=1.5R, R4=0.5R). In this way, by forming a relatively large R shape (a curved surface with curvature R3) at the end closest to the left shaft portion 202Lp, when protruding toward the fixed portion 201a, the flat portion of the left button pressing portion 202Lw is likely to come into contact with the second L button 43 or the second L button 65 first, and it is possible to prevent a deterioration in the operability caused by the end first coming into contact with the second L button 43 or the second L button 65. Also, by forming a relatively large R shape at the end closest to the left shaft portion 202Lp, it is possible to reduce the excessive load that the left button pressing portion 202Lw applies to the second L button 43 or the second L button 65.

[0186] The chamfered shape of the end of the lower surface of the left button pressing portion 202Lw does not have to be curved, and may be any shape that does not form a right angle. For example, the end of the lower surface of the left button pressing portion 202Lw may be beveled, or may be rounded with multiple curvatures. Regardless of the chamfered shape, the end of the lower surface of the left button pressing portion 202Lw closest to the left shaft portion 202Lp is formed to be more chamfered than the end farthest from the left shaft portion 202Lp.

[0187] 16 and 17, the right movable part 202R has the right operation part 202Re and the right button pressing part 202Rw provided at different positions in the axial direction of the right shaft part 202Rp. For example, in the direction from the front to the rear of the steering wheel type attachment 200, the part of the right operation part 202Re that is closest to the front among the parts that can be contacted by the user's finger is located on the rear side of the part of the right button pressing part 202Rw that is closest to the rear among the surfaces that can be contacted by the second R button 44 or the second R button 66. Specifically, the right button pressing portion 202Rw is provided on the front of the steering wheel type attachment 200, the right operation portion 202Re is provided on the back of the steering wheel type attachment 200, and the right operation portion 202Re and the right button pressing portion 202Rw are provided at positions that do not overlap in a direction from the front to the back (in the example of FIG. 17, the frontmost portion of the right operation portion 202Re that can be contacted by the user's finger and the rearmost portion of the right button pressing portion 202Rw that can be contacted by the second R button 44 or the second R button 66 are provided at positions spaced apart by a distance Y in the direction). That is, the axial direction of the right shaft portion 202Rp is provided in the front-rear direction of the steering wheel type attachment 200, and the right operation portion 202Re is provided rearward of the right button pressing portion 202Rw. In this way, by having a lever structure in which the force point and the action point are located at different positions in the axial direction rather than being located on the same line in a direction perpendicular to the axial direction of the fulcrum, it becomes possible to freely position the right operating part 202Re without being restricted by the positions of the left controller 3 and right controller 4 to which they are attached.

[0188] As shown in Figures 16 and 17, the right operation part 202Re and the right button pressing part 202Rw are provided at different positions in the axial direction of the right shaft part 202Rp. However, for example, in the case where the entire right movable part 202R is constructed by integral molding, it can be regarded that the right shaft part 202Rp is formed on one side of one arm, and the operation part 202Re and the right button pressing part 202Rw are formed on the other side of the one arm.

[0189] Next, an operation using the steering wheel type attachment 200 to which the left controller 3 or right controller 4 is attached will be described with reference to Fig. 18. Fig. 18 is a diagram showing an example of a state in which a user holds the steering wheel type attachment 200 to which the left controller 3 or right controller 4 is attached with both hands (i.e., the right hand and the left hand) and performs a game operation. In this embodiment, a process according to the operation content for the steering wheel type attachment 200 is executed in the main unit 2 based on data transmitted from the left controller 3 or right controller 4 attached to the steering wheel type attachment 200.

[0190] 18, the user operates the steering wheel type attachment 200 by gripping the rim of the steering wheel type attachment 200 with both hands and rotating the entire steering wheel type attachment 200 or pressing down the left operation part 202Le or the right operation part 202Re. In another example, the user can also operate the steering wheel type attachment 200 by moving the entire steering wheel type attachment 200 in the up-down direction, left-right direction, front-rear direction, etc., changing the orientation of the steering wheel type attachment 200, or operating the operation part of the left controller 3 or right controller 4 exposed on the front side of the steering wheel type attachment 200.

[0191] Information processing (e.g., game processing) is performed in the main unit 2 in response to an operation using the steering wheel type attachment 200. As an example, the main unit 2 operates a virtual object displayed on a display screen (e.g., the display 12 or a display device to which the main unit 2 is connected) in response to an operation using the steering wheel type attachment 200, and displays an image of a virtual space reflecting the operation of the virtual object on the display screen. For example, the main unit 2 changes the moving direction of a virtual object in response to a rotation operation on the steering wheel type attachment 200, and changes the moving speed of a virtual object in response to a press operation on the left operation part 202Le or the right operation part 202Re.

[0192] Here, the left controller 3 and the right controller 4 attached to the steering wheel type attachment 200 are provided with inertial sensors (acceleration sensor 104, angular velocity sensor 105, acceleration sensor 114, and angular velocity sensor 115), and data indicating the detection results of the inertial sensors can be wirelessly transmitted from the left controller 3 and the right controller 4 to the main unit 2. Then, the main unit 2 can calculate the attitude and / or movement of the left controller 3 and the right controller 4 (i.e., the attitude and / or movement of the steering wheel type attachment 200) using the detection results of the inertial sensors. In this embodiment, it is possible to control the operation of a virtual object according to the attitude and / or movement of the steering wheel type attachment 200.

[0193] In addition, the second L button 43 or the second L button 65 is pressed in response to a pressing operation on the left operation part 202Le, and data corresponding to the pressing operation of the operation button can be wirelessly transmitted from the left controller 3 or the right controller 4 to the main unit 2. In addition, the second R button 44 or the second R button 66 is pressed in response to a pressing operation on the right operation part 202Re, and data corresponding to the pressing operation of the operation button can be wirelessly transmitted from the left controller 3 or the right controller 4 to the main unit 2. Then, the main unit 2 can control the operation of a virtual object in response to a pressing operation on an operation button. In addition, it is also possible to operate various buttons and analog sticks provided on the front of the left controller 3 or the right controller 4 fixed to the steering wheel type attachment 200, and it is also possible to control the operation of a virtual object in response to the operation.

[0194] In the above description, an example in which the steering wheel type attachment 200 is provided with the movable part 202 has been used, but a movable part that performs other rotational movements may also be provided. Hereinafter, examples of steering wheel type attachments provided with a movable part that performs other rotational movements will be described with reference to Figs. 19 to 21. Fig. 19 is a vertical cross-sectional view showing an example of the structure of a movable part 302 provided in a steering wheel type attachment. Fig. 20 is a vertical cross-sectional view showing an example of the structure of a movable part 303 provided in a steering wheel type attachment. Fig. 21 is an internal structural view showing an example of the structure of a movable part 304 provided in a steering wheel type attachment.

[0195] In FIG. 19, the movable part 302 is provided at the rear of the attached controller so as to be rotatable around a fulcrum provided at the rear of the steering wheel type attachment. As shown in FIG. 19, the axial direction of the fulcrum of the movable part 302 is provided as the left-right direction of the steering wheel type attachment. The fulcrum of the movable part 302 is provided at the rear of the lower part of the operation button of the controller pressed by the movable part 302. The operation part (point of force) and the protruding part (point of action) of the movable part 302 are provided in front of the fulcrum, and the operation part is provided behind the protruding part. As a result, when the operation part of the movable part 302 is pressed downward, the protruding part also rotates in the same downward direction around the fulcrum. The amount of movement of the protruding part that moves due to the above-mentioned pressing is larger than the amount of movement of the operation part pressed down. Therefore, it is possible to reduce the amount of operation to press the operation button of the attached left controller 3 or right controller 4. In this way, the movable part 302 functions as a lever provided in the front-rear direction behind the steering wheel type attachment.

[0196] In FIG. 20, the movable part 303 is provided on the upper part of the attached controller so as to be rotatable around a fulcrum provided in front of the steering wheel type attachment. As shown in FIG. 20, the axial direction of the fulcrum of the movable part 303 is provided as the left-right direction of the steering wheel type attachment. The fulcrum of the movable part 303 is provided in front of the upper part of the operation button of the controller pressed by the movable part 303. The operation part (point of force) and the protruding part (point of action) of the movable part 303 are provided behind the fulcrum on the same straight line perpendicular to the axial direction of the fulcrum, and the operation part is provided behind the protruding part. As a result, when the operation part of the movable part 303 is pressed downward, the protruding part also rotates in the same downward direction around the fulcrum. The amount of movement of the protruding part that moves due to the above-mentioned pressing is smaller than the amount of movement of the operation part when pressed down. In this way, the movable part 303 functions as a lever provided in the front-rear direction above the steering wheel type attachment.

[0197] In FIG. 21, the movable part 304 is provided above the attached controller so as to be rotatable around a fulcrum provided above the steering wheel type attachment. As shown in FIG. 21, the axial direction of the fulcrum of the movable part 304 is provided as the front-rear direction of the steering wheel type attachment. The fulcrum of the movable part 304 is provided above the left side of the operation button of the controller pressed by the movable part 304. The operation part (point of force) and the protruding part (point of action) of the movable part 304 are provided to the right of the fulcrum and directly above the operation button of the controller pressed by the movable part 304, and the operation part is provided at a position directly above the protruding part. As a result, when the operation part of the movable part 304 is pressed downward, the protruding part provided directly below the operation part also rotates in the same downward direction around the fulcrum. The amount of movement of the protruding part that moves due to the above-mentioned pressing is the same as the amount of movement of the operation part pressed down. Therefore, the operating force for pressing the operating part is the same as the force for pressing the operation button of the attached left controller 3 or right controller 4, and since there is no leverage function, it becomes possible to operate the operating part of the movable part 304 with the same operating feel as when pressing the operation button of the left controller 3 or right controller 4 without an attachment. In this way, the movable part 304 is provided directly above the steering wheel-type attachment, and functions as an operating means without a leverage function.

[0198] Thus, in this embodiment, the steering wheel type attachment 200, which is an example of an accessory device, is detachable from either the left controller 3 or the right controller 4, and by attaching either one of them, processing according to the operation performed while holding the steering wheel type attachment 200 becomes possible. In addition, the steering wheel type attachment 200 is capable of operation according to the attitude and movement of the steering wheel type attachment 200 body, and is provided with a plurality of movable parts for operating the operation units provided on the left controller 3 and the right controller 4. Therefore, the user can also operate by moving the plurality of movable parts provided on the steering wheel type attachment 200 while moving the entire steering wheel type attachment 200, and a variety of operations are possible.

[0199] In the above embodiment, the method of detecting the movement and attitude of the left controller 3 and the right controller 4 attached to the steering wheel type attachment 200 is merely an example, and the movement and attitude may be detected using other methods or other data. For example, the movement and attitude may be calculated only from the angular velocity occurring in the left controller 3 and the right controller 4, only from the angular velocity occurring in the left controller 3 and the right controller 4, or by combining the angular velocity and acceleration occurring in the left controller 3 and the right controller 4. Even when only the acceleration occurring in the left controller 3 and the right controller 4 is detected, it is possible to calculate the direction in which the gravitational acceleration occurring in the left controller 3 and the right controller 4 occurs, and it goes without saying that the movement and attitude can be calculated by sequentially calculating the x, y and z axis directions based on the gravitational acceleration.

[0200] Furthermore, the main unit 2, the left controller 3, and the right controller 4 may be any device, and may be a portable game device, any portable electronic device (PDA (Personal Digital Assistant), mobile phone, personal computer, camera, tablet, etc.), etc. Furthermore, the device attached to the steering wheel type attachment 200 and transmitting operation data to the main unit 2 does not have to be a game controller. For example, the device attached to the steering wheel type attachment 200 may be a remote control device for remotely controlling / operating a device at a distant location, and a remote control device for controlling / operating a device other than a game device may be attached. For example, a remote control device for controlling / operating other devices such as a monitor, a personal computer, a camera, a tablet, a mobile phone, other household devices, outdoor devices, vehicles, etc. may be configured to be detachable from the steering wheel type attachment 200.

[0201] Moreover, the image displayed on the main unit 2 is displayed as a game image by the CPU 81 executing information processing (game processing) in response to the operation on the steering wheel type attachment 200. That is, the image displayed on the main unit 2 is generated by the CPU 81 of the main unit 2 executing information processing (for example, game processing), but at least a part of the processing for generating the image may be performed by another device. For example, if the main unit 2 is configured to be able to communicate with another device (for example, a server, another image display device, another game device, another mobile terminal, another information processing device), the above processing may be performed by the other device working in cooperation. In this way, by performing at least a part of the above processing by another device, processing similar to the above processing is possible. Moreover, the above information processing can be performed by one processor or by cooperation between multiple processors included in an information processing system composed of at least one information processing device. Moreover, in the above embodiment, the CPU 81 of the main unit 2 can execute a predetermined program to perform information processing, but a part or all of the above processing may be performed by a dedicated circuit provided in the main unit 2.

[0202] According to the above-mentioned modified example, the present invention can be realized in a so-called cloud computing system form or a distributed wide area network and local network system form. For example, in a distributed local network system form, the above-mentioned processing can be executed by cooperation between a stationary information processing device (stationary game device) and a portable information processing device (portable game device). In these system forms, there is no particular limitation on which device performs the above-mentioned processing, and it goes without saying that the present invention can be realized regardless of the division of processing load.

[0203] The program may be supplied to the main unit 2 through an external storage medium such as an external memory, or may be supplied to the device through a wired or wireless communication line. The program may be pre-recorded in a non-volatile storage device inside the device. The information storage medium for storing the program may be a non-volatile memory, a CD-ROM, a DVD, or an optical disk-shaped storage medium similar to these, a flexible disk, a hard disk, a magneto-optical disk, a magnetic tape, or the like. The information storage medium for storing the program may be a volatile memory for storing the program. Such a storage medium may be a recording medium that can be read by a computer or the like. For example, the various functions described above can be provided by having a computer or the like read and execute the programs from these recording media.

[0204] Although the present invention has been described in detail above, the above description is merely illustrative of the present invention in all respects and is not intended to limit its scope. It goes without saying that various improvements and modifications can be made without departing from the scope of the present invention. It is understood that the scope of the present invention should be interpreted only by the claims. It is also understood that a person skilled in the art can implement an equivalent scope based on the description of the present invention and technical common sense from the description of specific examples of the present invention. It should also be understood that the terms used in this specification are used in the sense commonly used in the field unless otherwise specified. Therefore, unless otherwise defined, all technical terms and technical terms used in this specification have the same meaning as commonly understood by a person skilled in the art to which this invention belongs. In the event of a conflict, this specification (including definitions) shall prevail. [Industrial Applicability]
