[0004] However, in the above-described conventional shutter mechanism, a mechanism is provided in which a deformable elastic body such as a leaf spring passes over a protrusion so that the lens cover (shutter) does not inadvertently move due to gravity, vibration, or the like, and a clicking feeling of movement is generated when the lens cover (shutter) is slid. Since the leaf spring and the protrusion are included, it is difficult to downsize the conventional shutter mechanism. SUMMARY

Detailed Implementation

[0028] Hereinafter, a light-shielding mechanism, an information processing device, and a method for manufacturing the light-shielding mechanism according to an embodiment of the present invention will be described with reference to the accompanying drawings.

[0029] Figure 1 This is an external view showing an example of a notebook PC 100 according to this embodiment.

[0030] like Figure 1 As shown, the notebook PC 100 includes a first frame 101 (frame), a second frame 102, a hinge mechanism 103, a display unit 104, a bezel 105, a camera 20, a light shield mechanism, and a cover 109. Furthermore, the notebook PC 100 is, for example, a clamshell-style notebook computer, and is an example of an information processing device.

[0031] The first frame 101 and the second frame 102 are formed in the shape of rectangular plates. The ends of the first frame 101 and the second frame 102 are connected to each other via a hinge mechanism 103. The second frame 102 is rotatable relative to the first frame 101 about a rotation axis formed by the hinge mechanism 103. The opening angle of the first frame 101 and the second frame 102 can be selected, for example, in the range of 0° and 180°.

[0032] The first frame 101 is equipped with a rectangular display unit 104.

[0033] The display unit 104 is, for example, a liquid crystal display (LCD), an organic EL (Electro-Luminescence) display, or a similar display device. The first frame 101 is also referred to as the display frame. The display unit 104 displays information (e.g., images) based on information processing performed by the notebook PC 100.

[0034] In addition, the first frame 101 has a border 105.

[0035] The bezel 105 is formed into a rectangular shape that surrounds the display unit 104. The camera 20 and the light hood mechanism 10 are mounted on the upper frame of the bezel 105, and a cover plate 109 is provided on the bezel 105 portion of the camera 20 and the light hood mechanism 10.

[0036] In addition, refer to Figures 2-4 The details of the camera 20 and the light-blocking mechanism 10 will be described later.

[0037] The second frame 102 is equipped with a keyboard 111 and a touchpad 112.

[0038] Keyboard 111 and touchpad 112 are examples of input devices. A battery (not shown), storage device (not shown), etc., are also housed in the second housing 102. The second housing 102 is also referred to as the system housing.

[0039] Next, refer to Figures 2-4 The structure of the camera 20 and the light-blocking mechanism 10 will be described.

[0040] Furthermore, in the description of the first frame 101, the light shield mechanism 10, and the camera 20, the positional relationship of each structure is explained using an XYZ orthogonal coordinate system. The direction of the rotation axis of the hinge mechanism 103 is referred to as the X direction. In addition, in the plane parallel to the display surface of the display unit 104 and the front surface of the bezel 105, the direction orthogonal to the X direction is referred to as the Y direction.

[0041] Additionally, the X direction is the extension direction of the upper frame of border 105 (the length direction of border 105). Furthermore, the Y direction is the width direction of the upper frame of border 105 (the width direction of the border). Viewing from a direction orthogonal to both the X and Y directions is called a "top view". The plane along the X and Y directions is called the XY plane.

[0042] In addition, the thickness direction of the first frame 101 is referred to as the Z direction.

[0043] Figure 2This is a cross-sectional view showing an example of the light-shielding mechanism 10 according to this embodiment. Additionally, Figure 3 This is an exploded perspective view showing an example of the light shielding mechanism 10 according to this embodiment.

[0044] like Figure 2 as well as Figure 3 As shown, the light-blocking mechanism 10 includes a camera 20, a light-blocking device 30, a base portion 40, a first component 41, and a second component 42.

[0045] In the first frame 101, from the back of the first frame 101 in the thickness direction (Z direction), the light shield mechanism 10 is arranged in the order of camera 20, base part 40, first piece member 41, second piece member 42, and light shield 30, and a frame 105 and a cover plate 109 are arranged to cover the light shield 30.

[0046] The light hood 30 is a component that can slide between a first position restricting the light received by the camera 20 (the light-receiving part 22 and the infrared light-receiving part 23 described later) and a second position releasing the light received restriction. The light hood 30 can move in the X direction (sliding direction). Here, the first position is, for example, a camera-prohibited position where the light hood 30 covers the lens of the camera 20 (the light-receiving part 22 and the infrared light-receiving part 23 described later), prohibiting the use of the camera 20. The second position is, for example, a camera-allowed position where the lens of the camera 20 (the light-receiving part 22 and the infrared light-receiving part 23 described later) is released from the cover of the light hood 30, allowing the use of the camera 20.

[0047] The light shield 30 has an operation section 31, an indicator hole 32, a visible light receiving hole 33, and an infrared light receiving hole 34.

[0048] The operation unit 31 is a component operated by the user when the light shader 30 is slidably moved in the X direction between the camera prohibited position (first position) and the camera permitted position (second position), and is disposed on the upper part of the plate-shaped light shader 30.

[0049] The indicator hole 32 is an aperture for indicating light and is configured to coincide with the indicator light 21 of the camera 20 in the Z direction (thickness direction of the first frame 101) at the camera-allowed position (second position) of the light shield 30.

[0050] The visible light receiving aperture 33 is a light receiving aperture for the light receiving part 22 of the visible light camera. It is configured to coincide with the light receiving part 22 of the camera 20 on the Z-direction (thickness direction of the first frame 101) axis at the camera-permitted use position (second position) of the light shield 30.

[0051] The infrared light receiving hole 34 is a hole for receiving light from the infrared light receiving part 23 of the infrared camera and for irradiating the infrared irradiation part 24. It is configured to coincide with the infrared light receiving part 23 and the infrared irradiation part 24 of the camera 20 on the Z-axis (thickness direction of the first frame 101) at the camera-permitted use position (second position) of the light shield 30.

[0052] The base portion 40 is a base for fixing the first component 41, is configured to cover part of the camera 20 (part of the camera substrate PB), and is fixed to the first frame 101.

[0053] The first component 41 is a sheet-shaped magnetic sheet that is fixed to the first frame 101 via the base portion 40. In the magnetized surface of the first component 41, a plurality of N poles PN and S poles PS are alternately arranged at a predetermined interval (spacing PT) in the sliding direction (X direction). Furthermore, the first component 41 is formed by cutting the magnetic sheet with a length SL1 in the sliding direction (X direction).

[0054] Here, the magnetic sheet is, for example, a sheet magnet used as a label or the like, pasted onto a metal whiteboard, with the N pole PN and the S pole PS being alternately magnetized at a specified spacing (spacing PT).

[0055] The second component 42 is fixed to the sheet-like magnetic sheet of the light shield 30 with its magnetized surface facing the magnetized surface of the first component 41. Like the first component 41, the second component 42 has multiple N poles (PN) and S poles (PS) alternately arranged at a predetermined interval (pitch PT) in the sliding direction (X direction). In the first position (camera prohibited position) and the second position (camera permitted position), when viewed from the direction opposite to the first component 41, the magnetization patterns of the N and S poles on the magnetized surface are reversed compared to the magnetization pattern of the first component 41.

[0056] The second component 42 is configured such that, in both the camera-prohibited and camera-permitted positions of the light shield 30, the magnetization patterns of the N-pole PN and S-pole PS on the magnetized surface are reversed compared to the first component 41. That is, in both the camera-prohibited and camera-permitted positions of the light shield 30, the S-pole PS of the second component 42 is positioned at the N-pole PN position of the first component 41, and the N-pole PN of the second component 42 is positioned at the S-pole PS position of the first component 41.

[0057] Furthermore, the second component 42 is formed by cutting out a magnetic sheet with a length SL2 in the sliding direction (X direction). The length SL2 of the second component 42 is shorter than the length SL1 of the first component 41. Additionally, refer to... Figure 5 as well as Figure 6The relationship between the length SL1 of the first component 41 and the length SL2 of the second component 42 will be described in detail later.

[0058] Figure 4 This is a structural diagram showing an example of the camera 20 in this embodiment. Figure 4 The structure of the overhead camera 20 is shown in the image.

[0059] like Figures 2-4 As shown, the camera 20 has an indicator light 21, a light receiving part 22, an infrared light receiving part 23, an infrared irradiation part 24, and a connector part 25 arranged on the camera substrate PB.

[0060] The camera substrate PB is fixed to the first frame 101 and is formed to be longer in the X direction and shorter in the Y direction in order to be housed in the frame 105.

[0061] Indicator light 21 is used as an indicator for camera 20.

[0062] The light-receiving unit 22 includes a light-receiving lens (not shown) and an image sensor such as a CCD (Charge Coupled Device) or CMOS (Complementary Metal Oxide Semiconductor) to generate image data based on the received visible light. The light-receiving unit 22 is, for example, a visible light camera.

[0063] The infrared light-receiving unit 23 includes a light-receiving lens (not shown) and an infrared image sensor such as a CCD or CMOS, and generates image data based on the received infrared light. The infrared light-receiving unit 23 is, for example, an infrared camera (IR camera).

[0064] The infrared irradiation unit 24 is, for example, an infrared light-emitting diode, which generates infrared light and irradiates it to the outside.

[0065] The connector section 25 is a connector for communication between the motherboard (not shown) of the notebook PC 100 and the camera 20, and is connected to a communication cable containing a power cord. The camera 20 receives power from the motherboard (not shown) of the notebook PC 100 via the connector section 25 and performs various communications with the motherboard (not shown).

[0066] In addition, such as Figure 3 As shown, the frame 105 and the cover plate 109 are configured to cover the light shield mechanism 10, which is configured to satisfy the width of the short side (width in the Y direction) of the frame 105 of the first frame 101.

[0067] The cover plate 109 has an indicator hole 35, a visible light receiving hole 36, an infrared light receiving hole 37, an infrared irradiation hole 38, and an operation hole 39.

[0068] The indicator hole 35 is an aperture for indicating light and is configured to coincide with the indicator light 21 and the indicator hole 32 of the light hood 30 in the camera-allowed position (second position) of the light hood 30 on the axis in the Z direction (thickness direction of the first frame 101).

[0069] The visible light receiving aperture 36 is a light-receiving hole for the light-receiving part 22 of the visible light camera. It is configured to coincide with the visible light receiving part 22 and the visible light receiving aperture 33 of the light-receiving part 22 and the light-receiving part 30 in the Z direction (thickness direction of the first frame 101) axis at the camera-permitted position (second position) of the light shader 30.

[0070] The infrared light-receiving hole 37 is a light-receiving hole for the infrared light-receiving part 23 of the infrared camera. It is configured to coincide with the infrared light-receiving part 23 and the infrared light-receiving hole 34 of the light-blocking part 30 on the axis in the Z direction (thickness direction of the first frame 101) at the camera-permitted position (second position) of the light-blocking 30.

[0071] The infrared illumination hole 38 is an aperture for irradiating infrared light from the infrared illumination section 24 of the infrared camera. It is configured to coincide with the infrared illumination section 24 and the infrared light receiving hole 34 of the light shield 30 on the axis in the Z direction (thickness direction of the first frame 101) at the camera-permitted position (second position) of the light shield 30.

[0072] The operation hole 39 is a hole for operating the operation part 31 of the light shield 30, and is formed so that the light shield 30 can slide and move through the operation of the operation part 31.

[0073] Next, the operation of the light-shielding mechanism 10 according to this embodiment will be described with reference to the accompanying drawings.

[0074] Figure 5 This is a diagram illustrating an example of the positional relationship between the first member 41 and the second member 42 of the camera 20 in the shading mechanism 10 according to this embodiment.

[0075] like Figure 5 As shown, when the light shield 30 is in the usable position, the first component 41 and the second component 42 are positioned with the second component 42 at the left end and the magnetization patterns of the N pole (PN) and the S pole (PS) are reversed. When the magnetization patterns of the first component 41 and the second component 42 are reversed, an attraction is generated between the first component 41 and the second component 42, resulting in a stable state and maintaining this position (the light shield 30 is in the usable position).

[0076] Furthermore, the length SL2 of the sliding movement direction of the second member 42 is shorter than the length SL1 of the sliding movement direction of the first member 41 by the amount of movement of the light shield 30 (the amount of length ΔSL).

[0077] In addition, in the permitted position, the indicator hole 32, visible light receiving hole 33, and infrared light receiving hole 34 of the light shield 30 coincide with the positions of the indicator light 21, light receiving part 22, infrared light receiving part 23, and infrared irradiation part 24, and the camera 20 becomes usable.

[0078] Next, if the light shield 30 is slidably moved from the permitted use position to the prohibited use position by operating the operation unit 31, a repulsive force is generated between the first member 41 and the second member 42 when the magnetization patterns of the first member 41 and the second member 42 are transferred from the reversed pattern to the same pattern.

[0079] Therefore, when the light shield 30 is slidably moved from the permitted use position to the prohibited use position, the repulsive force (repulsive force) creates resistance to the sliding movement of the light shield 30, and it moves past the same pattern and quickly transitions to the previous reversed pattern. As a result, by operating the operation unit 31, a clicking sensation is generated when passing through the same pattern between the first member 41 and the second member 42.

[0080] Figure 6 This is a diagram illustrating an example of the positional relationship between the first member 41 and the second member 42 of the camera 20 in the shading mechanism 10 according to this embodiment, which is a prohibited position.

[0081] like Figure 6 As shown, when the light shield 30 is in the prohibited position, the first component 41 and the second component 42 are positioned with the second component 42 at the right end and the magnetization patterns of the N pole (PN) and the S pole (PS) are reversed. With the magnetization patterns of the first component 41 and the second component 42 reversed, an attraction is generated between them, resulting in a stable state that maintains the position (the light shield 30 is in the prohibited position).

[0082] Furthermore, in the prohibited position, the indicator hole 32, visible light receiving hole 33, and infrared light receiving hole 34 of the light shield 30 are displaced from the positions of the indicator light 21, light receiving part 22, infrared light receiving part 23, and infrared irradiation part 24, thus obscuring the indicator light 21, light receiving part 22, infrared light receiving part 23, and infrared irradiation part 24. Therefore, the camera 20 becomes unusable.

[0083] Next, with reference to the accompanying drawings, the manufacturing method of the light-shielding mechanism 10 according to this embodiment will be described. Here, refer to... Figure 7 as well as Figure 8 The manufacturing methods of the first component 41 and the second component 42 are described.

[0084] Figure 7 This is a flowchart illustrating an example of a manufacturing method for the first component 41 and the second component 42 in this embodiment.

[0085] in addition, Figure 8 This is a diagram illustrating an example of the manufacturing method of the first component 41 and the second component 42 in this embodiment.

[0086] like Figure 7 As shown, firstly, with the two magnetic sheets (MS1, MS2) in a stable overlapping position, i.e., at a position where the magnetic poles of the upper and lower magnetic sheets are maximally intersected, they are cut to a predetermined length (length SL1) to form a first component 41 and a second component 42 (magnetic sheet MS2A) (step S101). That is, the two magnetic sheets (MS1, MS2) are cut, for example, like... Figure 8 In state ST11, the magnetization patterns overlap in such a way that they become inverted patterns. In this state, the two magnetic plates (MS1, MS2) are cut by the length SL1 of the sliding movement direction of the first component 41. Figure 8 State ST12).

[0087] Next, with the first component 41 and the second component 42 (magnetic sheet MS2A) aligned in a stable position, a fixing hole HL is formed (step S102). Figure 8 As shown in state ST13, two fixing holes HL are formed in the first component 41 and the second component 42 (magnetic sheet MS2A).

[0088] Furthermore, the two fixing holes HL are an example of positioning marks for the first piece 41 and the second piece 42. The process of step S103 corresponds to the process of attaching the positioning marks of the first piece 41 and the second piece 42 to the first piece 41 and the second piece 42 in a state where the first piece 41 and the second piece 42 are overlapped.

[0089] Next, the second component 42 (magnetic sheet MS2A) is cut by the amount of the light-shielding travel (length ΔSL), and shortened (step S103). That is, as... Figure 8 As shown in state ST14, the magnetic sheet MS2A of length SL1 is cut by a length ΔSL to make a second piece 42 of length SL2.

[0090] Furthermore, as shown in (1) below, the amount of travel of the shader (the amount of length ΔSL) is equivalent to the length obtained by multiplying the number of clicks N generated by the sliding movement of the shader 30 by twice the length of the specified spacing (spacing PT) (2×spacing PT).

[0091] Length ΔSL = Number of clicks N × 2 × Spacing PT···(1)

[0092] In addition, after performing step S103, the first component 41 is fixed to the base portion 40 using the fixing hole HL, and the second component 42 is fixed to the light shield 30 using the fixing hole HL.

[0093] Next, refer to Figure 9 as well as Figure 10 A modified example of the manufacturing method of the first component 41 and the second component 42 will be described.

[0094] When the first component 41 and the second component 42 are made from two very long magnetic sheets, if the two magnetic sheets are overlapped, due to the deviation in the spacing PT (magnetization gap) between the N pole PN and the S pole PS, sometimes the same pole patterns overlap and produce mutually repelling parts. In this modified example, a modified example of making the first component 41 and the second component 42 using two very long magnetic sheets will be described.

[0095] Figure 9 This is a flowchart illustrating a variation of the manufacturing method of the first component 41 and the second component 42 in this embodiment.

[0096] in addition, Figure 10 This is a diagram illustrating a variation of the manufacturing method of the first component 41 and the second component 42 in this embodiment.

[0097] like Figure 9 As shown, firstly, with the two magnetic sheets (MS1a, MS2a) aligned in a stable position, they are simultaneously cut to a first length (length L1) to form two magnetic sheets of the first length (length L1) (step S201). That is, the two magnetic sheets (MS1a, MS2a) are cut, for example, like... Figure 10 In state ST21, the magnetization patterns are aligned so that they are reversed. In this state, the two magnetic pieces (MS1a, MS2a) are cut by a length L1. Furthermore, the length L1 is a value longer than the length SL1 of the first piece 41.

[0098] exist Figure 10In the example shown, magnetic sheets (MS3-1, MS4-1), magnetic sheets (MS3-2, MS4-2), and magnetic sheets (MS3-3, MS4-3) are made as two magnetic sheets (MS3, MS4) of length L1.

[0099] Next, with the two magnetic pieces (MS3, MS4) of the first length (length L1) overlapping in a stable position again, they are simultaneously cut at the second length (length L2) to form the first component 41 and the second component 42 (step S202). That is, as... Figure 10 As shown in state ST22, the two magnetic sheets (MS3-1, MS4-1), the two magnetic sheets (MS3-2, MS4-2), and the two magnetic sheets (MS3-3, MS4-3) are overlapped with their magnetization patterns reversed. In this state, the two magnetic sheets (MS3, MS4) are cut with a length L2 (the length SL1 of the first component 41).

[0100] The result, such as Figure 10 As shown in state ST23, the first component 41-1 and magnetic sheet MS2A-1, the first component 41-2 and magnetic sheet MS2A-2, the first component 41-3 and magnetic sheet MS2A-3 are made, which are the first component 41 and the second component 42 (magnetic sheet MS2A) with length L2 (length SL1 of the first component 41).

[0101] Furthermore, through the process of step S201 described above, the vertical repulsion caused by the overlap of the long magnetic sheets (MS1a, MS2a) can be reduced in the subsequent step S202.

[0102] The following steps S203 and S204 are related to... Figure 7 The processes shown in S102 and S103 are as follows ( Figure 8 The states ST13 and ST14 are the same, so their descriptions are omitted here.

[0103] As described above, the light-shielding mechanism 10 according to this embodiment includes a camera 20, a light-shielding device 30, a first member 41, and a second member 42. The camera 20 has a light-receiving portion 22 and is mounted on a first frame 101 (frame) of a notebook PC 100 (information processing device). The light-shielding device 30 is slidable between a first position that restricts light reception of the light-receiving portion 22 and a second position that releases the restriction of light reception. The first member 41 is a sheet-like magnetic sheet fixed relative to the first frame 101 (frame), and has a plurality of N poles PN and S poles PS alternately arranged at a predetermined interval (pitch PT) in the sliding direction (X direction). The second member 42 is a sheet-like magnetic sheet fixed relative to the light-shielding device 30 such that the magnetized surface of the sheet faces the magnetized surface of the first member 41. Furthermore, in the first position (the permitted use position of the camera 20) and the second position (the prohibited use position of the camera 20), the magnetization patterns of the N poles PN and S poles PS on the magnetized surface of the second component 42 are reversed compared to those of the first component 41, and multiple N poles PN and S poles PS are alternately arranged at a predetermined interval (pitch PT) in the sliding movement direction. That is, multiple N poles and S poles are alternately arranged at a predetermined interval in the sliding movement direction, and in the first and second positions, when viewed from the direction opposite to the first component 41, the magnetization patterns of the N poles and S poles on the magnetized surface are reversed compared to those of the first component 41.

[0104] Therefore, when the second member 42, which is fixed to the light shield 30, is slidably moved by the light shield mechanism 10 according to this embodiment, a repulsive force is generated at the position where the magnetization patterns of the first member 41 and the second member 42 are aligned, and an attractive force is generated at the position where the magnetization patterns of the first member 41 and the second member 42 are reversed. Thus, when moving from the position where the magnetization patterns are aligned to the position where the magnetization patterns are reversed, it slides quickly with a weak force; when moving from the position where the magnetization patterns are reversed to the position where the magnetization patterns are aligned, strong resistance is generated, making it difficult to slide. Accordingly, the light shield mechanism 10 according to this embodiment can generate a clicking sensation through the sliding movement of the light shield 30.

[0105] Furthermore, according to this embodiment, the light shield mechanism 10 is in a first position (the position where the camera 20 is allowed to be used) and a second position (the position where the camera 20 is prohibited from being used), where the magnetization patterns of the first component 41 and the second component 42 are reversed, so the light shield 30 will not move unintentionally due to gravity, vibration, etc.

[0106] Furthermore, in the light-shielding mechanism 10 according to this embodiment, since it is not necessary to provide elastic bodies such as leaf springs or protrusions for generating a click sensation, the structure can be simplified and miniaturized. Therefore, the light-shielding mechanism 10 according to this embodiment can generate an appropriate click sensation through the movement of the light-shielding 30, and is also miniaturized.

[0107] For example, in the light shielding mechanism 10 according to this embodiment, by using a magnetic sheet, it can be housed on the camera substrate PB, thereby shortening the dimension of the short side direction (Y direction) of the frame 105 and shortening the dimension of the thickness direction (Z direction) of the first frame 101.

[0108] Furthermore, in this embodiment, the length SL2 of the sliding movement direction of the second member 42 is shorter than the length SL1 of the sliding movement direction of the first member 41 by an amount of movable light shield 30 (the amount of length ΔSL).

[0109] Therefore, the shading mechanism 10 according to this embodiment can appropriately set the amount of movement of the shading 30, and can set the first position (the allowed position of the camera 20) and the second position (the prohibited position of the camera 20) to appropriate positions.

[0110] In addition, in this embodiment, the length SL2 of the sliding movement direction of the second member 42 is shorter than the length SL1 of the sliding movement direction of the first member 41. The length is obtained by multiplying the number of click sensations N generated by the sliding movement of the light shield 30 by twice the specified spacing (spacing PT) (2×spacing PT) (refer to the above formula (1)).

[0111] Therefore, the shading mechanism 10 according to this embodiment can appropriately generate the number of click sensations generated when the shading 30 slides.

[0112] Furthermore, the notebook PC 100 (information processing device) according to this embodiment includes the above-described light shield mechanism 10 and a first frame 101 on which the light shield mechanism 10 is mounted.

[0113] Therefore, the notebook PC 100 (information processing device) according to this embodiment can miniaturize the light shield mechanism 10, and thus, by equipping the light shield mechanism 10, it can be miniaturized and made lighter.

[0114] In this embodiment, a display unit 104 is mounted on the first frame 101. A light shield mechanism 10 is disposed on the frame 105 portion surrounding the display unit 104 and provided on the first frame 101.

[0115] Therefore, the notebook PC 100 according to this embodiment can shorten the dimension of the short side (Y direction) of the bezel 105 and shorten the dimension of the thickness direction (Z direction) of the first frame 101. Consequently, the notebook PC 100 according to this embodiment can increase the size of the display unit 104. Furthermore, the notebook PC 100 according to this embodiment can reduce the dimension of the first frame 101 in the thickness direction, thus enabling the first frame 101 to be miniaturized and made thinner.

[0116] Furthermore, the manufacturing method of the light-shielding mechanism 10 according to this embodiment includes a first step ( Figure 7 Step S101, the second step ( Figure 7 Step S102 and the third step Figure 7 (Step S103). Furthermore, the light-shielding mechanism 10 includes the aforementioned light-shielding 30, first member 41, and second member 42. The first step involves aligning the two magnetic plates (MS1, MS2) in a stable position with their magnetization faces facing each other and their N poles (PN) and S poles (PS) reversed. The first member 41 and the second member 42 (magnetic plate MS2A) are then cut out from these two magnetic plates (MS1, MS2). The second step involves attaching positioning marks to the first member 41 and the second member 42 (magnetic plate MS2A) with their positions aligned. The third step involves shortening the movable portion of the light-shielding 30 by cutting the second member 42.

[0117] Therefore, the manufacturing method of the light shield mechanism 10 according to this embodiment can manufacture suitable first component 41 and second component 42, and can miniaturize the light shield mechanism 10 and the notebook PC 100.

[0118] In addition, in this embodiment, the positioning mark is a fixing hole HL for fixing the first piece 41 and the second piece 42. The second process is to form the fixing hole HL for fixing while the first piece 41 and the second piece 42 (magnetic sheet MS2A) are aligned.

[0119] Therefore, the manufacturing method of the light shield mechanism 10 according to this embodiment can fix the first piece 41 and the second piece 42 in an appropriate positional relationship by forming a fixing hole HL.

[0120] In addition, in this embodiment, the first process ( Figure 9The steps S201 and S202 are as follows: with the two magnetic pieces (MS1a, MS2a) overlapping, they are cut with a first length L1 in the sliding direction, so that the two magnetic pieces after the first length L1 are aligned in a stable position with their magnetization faces facing each other, and their N pole PN and S pole PS reversing each other. Then, they are cut with a second length L2 (SL1) shorter than the first length L1, to cut out the first component 41 and the second component 42 (magnetic piece MS2A).

[0121] Therefore, the manufacturing method of the light shield mechanism 10 according to this embodiment can manufacture appropriate first member 41 and second member 42 even when the first member 41 and the second member 42 are manufactured from two very long magnetic sheets (MS1a, MS2a), i.e., when the deviation of the pitch PT (magnetization pitch) becomes a problem, and can make the light shield mechanism 10 and the notebook PC 100 miniaturized.

[0122] Furthermore, the present invention is not limited to the embodiments described above, and can be modified within the scope of the present invention without departing from its spirit.

[0123] For example, in the above embodiment, the information processing device is described as a notebook PC 100, but it is not limited to this. For example, it may also be a tablet terminal device, a smartphone, an electronic device with a camera, or other information processing devices.

[0124] Furthermore, in the above embodiment, an example of mounting a light shield mechanism 10 on the frame 105 portion of the first frame 101 having the display portion 104 has been described, but it is not limited to this. For example, the light shield mechanism 10 may also be mounted on other frames (parts) such as frames that do not have the display portion 104 or parts other than the frame 105.

[0125] Furthermore, in the above embodiments, an example of a camera 20 using a light shield mechanism 10, comprising an indicator light 21, a visible light receiving section 22 (visible light camera), an infrared light receiving section 23 (infrared camera), and an infrared illumination section 24, has been described. However, this is not a limitation, and other camera structures are also possible. For example, the camera 20 may also be configured without some of the following structures: indicator light 21, visible light receiving section 22 (visible light camera), infrared light receiving section 23 (infrared camera), and infrared illumination section 24.

[0126] Furthermore, in the above embodiments, an example of using a fixing hole HL was described as a positioning mark, but it is not limited to this; other marks such as symbols may also be used. Additionally, the positioning mark may be added based on printing or other processing methods.

[0127] Furthermore, the number of magnetization patterns (number of magnetic pole patterns) of the first component 41 and the second component 42 is not limited to the above-described embodiment and can be changed depending on the information processing device used.
