Description

[Technical field]

[0001] The present invention relates to a shutter mechanism, an information processing device, and a method for manufacturing a shutter mechanism. [Background technology]

[0002] In recent years, information processing devices such as notebook personal computers (notebook PCs) are known to be equipped with a shutter mechanism that slides a lens cover (shutter) that covers the camera to prevent unintentional photography with the built-in camera (see, for example, Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2020-201886 A Summary of the Invention [Problem to be solved by the invention]

[0004] However, in the conventional shutter mechanism as described above, a mechanism is provided in which a deformable elastic body such as a leaf spring overcomes a protrusion to prevent the lens cover (shutter) from accidentally moving due to gravity, vibration, etc., and to generate a clicking sensation when the lens cover (shutter) is slid. Because the conventional shutter mechanism includes a leaf spring and a protrusion, it is difficult to reduce the size of the mechanism.

[0005] The present invention has been made to solve the above problems, and its object is to provide a shutter mechanism, an information processing device, and a method for manufacturing a shutter mechanism that can be miniaturized while producing an appropriate clicking sensation when the shutter moves. [Means for solving the problem]

[0006] In order to solve the above problems, one aspect of the present invention is a shutter mechanism comprising: a camera having a light receiving unit and mounted on a housing of an information processing device; a shutter that is slidable between a first position that restricts light reception by the light receiving unit and a second position that releases the restriction on light reception; a first sheet member that is a sheet-like magnetic sheet fixed relatively to the housing, in which a plurality of N poles and S poles are arranged alternately at a predetermined pitch in the sliding movement direction; and a second sheet member that is a sheet-like magnetic sheet fixed relatively to the shutter so that the magnetized surface of the sheet faces the magnetized surface of the first sheet member, in which a plurality of N poles and S poles are arranged alternately at a predetermined pitch in the sliding movement direction, and in which at the first position and the second position, the magnetization pattern of the N poles and S poles on the magnetized surface is inverted from the magnetization pattern of the first sheet member when viewed from the direction facing the first sheet member.

[0007] In addition, one aspect of the present invention is that in the above-mentioned shutter mechanism, the length of the second sheet member in the sliding movement direction may be shorter than the length of the first sheet member in the sliding movement direction by an amount equivalent to the movement of the shutter.

[0008] In addition, one aspect of the present invention is that in the above-mentioned shutter mechanism, the length of the second sheet member in the sliding movement direction may be shorter than the length of the first sheet member in the sliding movement direction by a length obtained by multiplying the number of clicking sensations generated by the sliding movement of the shutter by twice the length of the specified pitch.

[0009] Another aspect of the present invention is an information processing device including the above-mentioned shutter mechanism and the housing in which the shutter mechanism is mounted.

[0010] In addition, one aspect of the present invention is that, in the above-mentioned information processing device, the housing is equipped with a display unit, and the shutter mechanism is arranged in a bezel portion provided on the housing surrounding the display unit.

[0011] In addition, in one aspect of the present invention, in the information processing device described above, the first sheet member and the second sheet member may be arranged in the bezel portion so as to overlap each other in a thickness direction of the housing.

[0012] Also, one aspect of the present invention includes a camera having a light receiving unit and mounted on a housing of an information processing device, a shutter that is slidable between a first position that restricts light reception by the light receiving unit and a second position that releases the restriction on light reception, a sheet-like magnetic sheet fixed relatively to the housing, the first sheet member having a plurality of N poles and S poles arranged alternately at a predetermined pitch in the sliding movement direction, and a sheet-like magnetic sheet fixed relatively to the shutter so that a magnetized surface of the sheet faces a magnetized surface of the first sheet member, the plurality of N poles and S poles are arranged alternately at a predetermined pitch in the sliding movement direction, and at the first position and the second position, the magnetization pattern of the N poles and S poles of the magnetized surface is different from that of the first sheet member. A manufacturing method for a shutter mechanism comprising a second sheet member having a magnetization pattern that is inverted to that of the first sheet member when viewed from an opposing direction, the manufacturing method for a shutter mechanism including: a first step of stacking two of the magnet sheets with their magnetized surfaces facing each other in a stable position where the N pole and the S pole are inverted to each other and cutting out the first sheet member and the second sheet member from the two magnet sheets; a second step of adding positioning marks for the first sheet member and the second sheet member to the first sheet member and the second sheet member in the stacked state; and a third step of cutting the second sheet member to a length that is short enough to allow movement of the shutter.

[0013] In addition, one aspect of the present invention may be such that, in the above-mentioned method of manufacturing a shutter mechanism, the positioning mark is a fixing hole for fixing the first sheet member and the second sheet member, and the second step is a step of forming a fixing hole for fixing the first sheet member and the second sheet member in the overlapping state.

[0014] Moreover, one aspect of the present invention may be a process for cutting two of the magnet sheets, while they are stacked, to a first length in the direction of slide movement, and then cutting the two cut magnet sheets of the first length to a second length shorter than the first length, while stacking the magnetized surfaces facing each other in a position where the N pole and the S pole are inverted and stable, to cut out the first sheet member and the second sheet member. Effect of the Invention

[0015] According to the above aspects of the present invention, it is possible to reduce the size of the device while still providing an appropriate clicking sensation upon shutter movement. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0017] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A shutter mechanism, an information processing device, and a method for manufacturing a shutter mechanism according to an embodiment of the present invention will be described below with reference to the drawings.

[0018] FIG. 1 is an external view showing an example of a notebook PC 100 according to this embodiment. 1, the notebook PC 100 includes a first housing 101 (housing), a second housing 102, a hinge mechanism 103, a display unit 104, a bezel 105, a camera 20, a shutter mechanism, and a cover plate 109. The notebook PC 100 is, for example, a clamshell notebook personal computer, and is an example of an information processing device.

[0019] The first housing 101 and the second housing 102 are rectangular plate-shaped. Ends of the first housing 101 and the second housing 102 are connected via a hinge mechanism 103. The second housing 102 is rotatable relative to the first housing 101 around a rotation axis formed by the hinge mechanism 103. The opening angle between the first housing 101 and the second housing 102 can be selected, for example, within a range of 0° or more and 180° or less.

[0020] The first housing 101 is equipped with a rectangular display unit 104. The display unit 104 is a display device such as a liquid crystal display or an organic EL (EL: Electro-Luminescence) display. The first housing 101 is also called a display housing. The display unit 104 displays information (e.g., images, etc.) based on information processing executed by the notebook PC 100.

[0021] In addition, the first housing 101 has a bezel 105 . Bezel 105 is formed in a rectangular shape surrounding display unit 104. Camera 20 and shutter mechanism 10 are mounted on an upper frame portion of bezel 105, and a cover plate 109 is provided on the bezel 105 portion of camera 20 and shutter mechanism 10. The camera 20 and the shutter mechanism 10 will be described in detail later with reference to FIGS.

[0022] The second housing 102 is equipped with a keyboard 111 and a touch pad 112 . The keyboard 111 and the touch pad 112 are examples of input devices. The second housing 102 also includes a battery (not shown), a storage device (not shown), and the like. The second housing 102 is also called a system housing.

[0023] Next, the configurations of the camera 20 and the shutter mechanism 10 will be described with reference to FIGS.

[0024] In the explanation of first housing 101, shutter mechanism 10, and camera 20, the positional relationship of each component may be explained using an XYZ Cartesian coordinate system. The direction of the rotation axis of hinge mechanism 103 is referred to as the X direction. Moreover, in a plane parallel to the display surface of display unit 104 and the front surface of bezel 105, the direction perpendicular to the X direction is referred to as the Y direction.

[0025] The X direction is the extension direction of the upper frame of bezel 105 (the length direction of bezel 105). The Y direction is the width direction of the upper frame of bezel 105 (the width direction of the bezel). Viewing from a direction perpendicular to the X and Y directions is called a "planar view." A plane along the X and Y directions is called an XY plane. The thickness direction of first housing 101 is referred to as the Z direction.

[0026] Fig. 2 is a cross-sectional view showing an example of the shutter mechanism 10 according to the present embodiment, and Fig. 3 is an exploded perspective view showing an example of the shutter mechanism 10 according to the present embodiment.

[0027] As shown in FIGS. 2 and 3, the shutter mechanism 10 includes a camera 20, a shutter 30, a base portion 40, a first sheet member 41, and a second sheet member . In the first housing 101, from the rear portion of the first housing 101 in the thickness direction (Z direction), the shutter mechanism 10 is arranged in the following order: camera 20, base portion 40, first sheet member 41, second sheet member 42, and shutter 30, and further, a bezel 105 and a cover plate 109 are arranged to cover the shutter 30.

[0028] The shutter 30 is a member that can slide between a first position that restricts light reception by the camera 20 (light receiving unit 22 and infrared receiving unit 23 described later) and a second position that lifts the restriction on light reception. The shutter 30 can move in the X direction (sliding direction). Here, the first position is, for example, a camera use prohibited position that prohibits use of the camera 20 by covering the lens of the camera 20 (light receiving unit 22 and infrared receiving unit 23 described later) with the shutter 30. Also, the second position is, for example, a camera use permitted position that permits use of the camera 20 by removing the lens of the camera 20 (light receiving unit 22 and infrared receiving unit 23 described later) from the cover of the shutter 30.

[0029] The shutter 30 has an operation portion 31, an indicator hole 32, a visible light receiving hole 33, and an infrared light receiving hole . The operating unit 31 is a member that is operated by the user when sliding the shutter 30 in the X direction between a camera use prohibited position (first position) and a camera use permitted position (second position), and is located on the top of the plate-shaped shutter 30.

[0030] The indicator hole 32 is a hole for indicator light, and is positioned so as to overlap with an indicator lamp 21 of the camera 20, which will be described later, on the axis in the Z direction (thickness direction of the first housing 101) when the shutter 30 is in the camera usage permission position (second position).

[0031] The visible light receiving hole 33 is a hole for receiving light by the light receiving unit 22 of the visible light camera, and is positioned so as to overlap with the light receiving unit 22 of the camera 20 on the axis in the Z direction (thickness direction of the first housing 101) when the shutter 30 is in the camera usage permitted position (second position).

[0032] The infrared receiving hole 34 is a hole for receiving light by the infrared receiving unit 23 of the infrared camera and for emitting light by the infrared irradiating unit 24, and is positioned so as to overlap with the infrared receiving unit 23 and infrared irradiating unit 24 of the camera 20 on the axis in the Z direction (thickness direction of the first housing 101) when the shutter 30 is in the camera usage permitted position (second position).

[0033] The base portion 40 is a base for fixing the first sheet member 41, and is disposed so as to cover a part of the camera 20 (a part of the camera board PB), and is fixed to the first housing 101. The first sheet member 41 is a sheet-like magnet sheet relatively fixed to the first housing 101 via the base portion 40. The first sheet member 41 has a magnetized surface on which N poles PN and S poles PS are alternately arranged at a predetermined pitch (pitch PT) in the sliding movement direction (X direction). The first sheet member 41 is formed by cutting a magnet sheet to a length SL1 in the sliding movement direction (X direction).

[0034] Here, the magnetic sheet is a sheet-like magnet that is attached to a metal whiteboard or the like to be used as a label or the like, and is magnetized with north poles PN and south poles PS alternately at a predetermined pitch (pitch PT).

[0035] The second sheet member 42 is a sheet-like magnet sheet fixed relatively to the shutter 30 so that the magnetized surface of the sheet faces the magnetized surface of the first sheet member 41. The second sheet member 42 has a plurality of N poles PN and S poles PS arranged alternately at a predetermined pitch (pitch PT) in the sliding movement direction (X direction) like the first sheet member 41. The second sheet member 42 has a plurality of N poles and S poles arranged alternately at a predetermined pitch in the sliding movement direction, and at the first position (camera use prohibited position) and the second position (camera use permitted position), the magnetization pattern of the N poles and S poles on the magnetized surface is reversed to the magnetization pattern of the first sheet member 41 when viewed from the direction facing the first sheet member 41.

[0036] The second sheet member 42 is configured such that the magnetization pattern of the N pole PN and S pole PS on the magnetized surface is reversed to that of the first sheet member 41 in the camera usage prohibited position and the camera usage permitted position of the shutter 30. That is, in the camera usage prohibited position and the camera usage permitted position of the shutter 30, the S pole PS of the second sheet member 42 is disposed at the position of the N pole PN of the first sheet member 41, and the N pole PN of the second sheet member 42 is disposed at the position of the S pole PS of the first sheet member 41.

[0037] The second sheet member 42 is formed by cutting a magnet sheet to a length SL2 in the sliding movement direction (X direction). The length SL2 of the second sheet member 42 is shorter than the length SL1 of the first sheet member 41. The relationship between the length SL1 of the first sheet member 41 and the length SL2 of the second sheet member 42 will be described in detail later with reference to FIGS. 5 and 6.

[0038] Fig. 4 is a configuration diagram showing an example of the camera 20 in this embodiment. Fig. 4 shows the configuration of the camera 20 in a plan view. As shown in FIGS. 2 to 4, in the camera 20, an indicator lamp 21, a light receiving section 22, an infrared light receiving section 23, an infrared light emitting section 24, a connector section 25, and the like are arranged on a camera board PB.

[0039] The camera board PB is fixed to the first housing 101 and is formed to be long in the X direction and short in the Y direction so as to fit within the bezel 105. The indicator lamp 21 is used as an indicator for the camera 20 .

[0040] The light receiving unit 22 has a light receiving lens (not shown) and an image sensor such as a charge coupled device (CCD) or a complementary metal oxide semiconductor (CMOS), and generates image data based on the received visible light. The light receiving unit 22 is, for example, a visible light camera.

[0041] The infrared receiving unit 23 has a light receiving lens and an infrared image sensor such as a CCD or CMOS (not shown), and generates image data based on the received infrared light. The infrared receiving unit 23 is, for example, an infrared camera (IR camera).

[0042] The infrared irradiating unit 24 is, for example, an infrared light emitting diode, which generates infrared light and irradiates it to the outside.

[0043] The connector unit 25 is a connector for performing communication between the motherboard (not shown) of the notebook PC 100 and the camera 20, and is connected to a communication cable including a power line. The camera 20 receives power from the motherboard (not shown) of the notebook PC 100 via the connector unit 25, and performs various communications with the motherboard (not shown) of the notebook PC 100.

[0044] As shown in FIG. 3, the bezel 105 and the cover plate 109 are arranged to cover the shutter mechanism 10, and the shutter mechanism 10 is configured to fit within the short side width (width in the Y direction) of the bezel 105 of the first housing 101.

[0045] The cover plate 109 has an indicator hole 35 , a visible light receiving hole 36 , an infrared light receiving hole 37 , an infrared light emitting hole 38 , and an operation hole 39 .

[0046] The indicator hole 35 is a hole for indicator light, and is positioned so as to overlap with the indicator lamp 21 and the indicator hole 32 of the shutter 30 on the axis in the Z direction (thickness direction of the first housing 101) when the shutter 30 is in the camera usage permitted position (second position).

[0047] The visible light receiving hole 36 is a hole for receiving light by the light receiving unit 22 of the visible light camera, and is positioned so as to overlap with the light receiving unit 22 and the visible light receiving hole 33 of the shutter 30 on the axis in the Z direction (thickness direction of the first housing 101) when the shutter 30 is in the camera usage permitted position (second position).

[0048] The infrared receiving hole 37 is a hole for receiving light by the infrared receiving unit 23 of the infrared camera, and is positioned so as to overlap with the infrared receiving unit 23 and the infrared receiving hole 34 of the shutter 30 on the axis in the Z direction (thickness direction of the first housing 101) when the shutter 30 is in the camera usage permitted position (second position).

[0049] The infrared irradiation hole 38 is a hole for emitting infrared rays from the infrared irradiation unit 24 of the infrared camera, and is positioned so as to overlap with the infrared irradiation unit 24 and the infrared receiving hole 34 of the shutter 30 on the axis in the Z direction (thickness direction of the first housing 101) when the shutter 30 is in the camera usage permission position (second position).

[0050] The operation hole 39 is a hole for operating the operation portion 31 of the shutter 30, and is formed so that the shutter 30 can be slid by operating the operation portion 31.

[0051] Next, the operation of the shutter mechanism 10 according to the present embodiment will be described with reference to the drawings. FIG. 5 is a diagram illustrating an example of the positional relationship between the first sheet member 41 and the second sheet member 42 when the camera 20 of the shutter mechanism 10 according to the present embodiment is in the usage permission position.

[0052] 5, when the shutter 30 is in the usage permission position, the first sheet member 41 and the second sheet member 42 are in a position where the magnetization patterns of the N pole PN and the S pole PS are inverted with the second sheet member 42 in the leftmost position. When the magnetization patterns of the first sheet member 41 and the second sheet member 42 are inverted with each other, an attractive force (attractive force) is generated between the first sheet member 41 and the second sheet member 42, resulting in a stable state, and the position (shutter 30 is in the usage permission position) is maintained.

[0053] The length SL2 of the second sheet member 42 in the sliding movement direction is shorter than the length SL1 of the first sheet member 41 in the sliding movement direction by the amount by which the shutter 30 can move (length ΔSL). In addition, when in the usable position, the shutter 30 has an indicator hole 32, a visible light receiving hole 33, and an infrared receiving hole 34 that overlap with the indicator lamp 21, the light receiving section 22, the infrared receiving section 23, and the infrared emitting section 24, making the camera 20 usable.

[0054] Next, when the shutter 30 is slid from the permitted position to the prohibited position by operating the operating unit 31, a repulsive force (fleeting force) is generated between the first sheet member 41 and the second sheet member 42 as the magnetization patterns of the first sheet member 41 and the second sheet member 42 transition from reversed patterns to the same pattern.

[0055] Therefore, when the shutter 30 is slid from the use permitted position to the use prohibited position, a repulsive force (a rebound force) resists the sliding movement of the shutter 30, and the shutter 30 jumps over the same pattern and transitions to the inverted pattern ahead in a short period of time. As a result, a clicking sensation occurs when the shutter 30 passes through the same pattern between the first sheet member 41 and the second sheet member 42 by operating the operating unit 31.

[0056] FIG. 6 is a diagram illustrating an example of the positional relationship between the first sheet member 41 and the second sheet member 42 when the camera 20 of the shutter mechanism 10 according to the present embodiment is in the prohibited position. 6, when the shutter 30 is in the prohibited position, the first sheet member 41 and the second sheet member 42 are in a position where the magnetization patterns of the N pole PN and the S pole PS are inverted with the second sheet member 42 in the rightmost position. When the magnetization patterns of the first sheet member 41 and the second sheet member 42 are inverted with each other, an attractive force (attractive force) is generated between the first sheet member 41 and the second sheet member 42, resulting in a stable state, and the position (shutter 30 is in the prohibited position) is maintained.

[0057] In addition, in the disabled position, the shutter 30 is in a state where the indicator hole 32, the visible light receiving hole 33, and the infrared light receiving hole 34 are out of position with the indicator lamp 21, the light receiving section 22, the infrared receiving section 23, and the infrared emitting section 24, and cover and conceal the indicator lamp 21, the light receiving section 22, the infrared receiving section 23, and the infrared emitting section 24. This makes the camera 20 unusable.

[0058] Next, a method for manufacturing the shutter mechanism 10 according to the present embodiment will be described with reference to the drawings. Here, a method for manufacturing the first sheet member 41 and the second sheet member 42 will be described with reference to Figs.

[0059] FIG. 7 is a flowchart showing an example of a method for manufacturing the first sheet member 41 and the second sheet member 42 in this embodiment. FIG. 8 is a diagram illustrating an example of a manufacturing method for the first sheet member 41 and the second sheet member 42 in this embodiment.

[0060] As shown in Fig. 7, first, two magnet sheets (MS1, MS2) are cut to a predetermined length (length SL1) at a position where the magnetic poles of the upper and lower magnet sheets are maximally staggered, to form the first sheet member 41 and the second sheet member 42 (magnet sheet MS2A) (step S101). That is, the two magnet sheets (MS1, MS2) are overlapped so that the magnetization patterns are inverted to each other, for example, as in state ST11 of Fig. 8. In this state, the two magnet sheets (MS1, MS2) are cut to the length SL1, which is the length in the sliding movement direction of the first sheet member 41 (state ST12 of Fig. 8).

[0061] Next, in a state where the first sheet member 41 and the second sheet member 42 (magnet sheet MS2A) are overlapped in a stable position, fixing holes HL are formed (step S102). As shown in state ST13 of FIG. 8, two fixing holes HL are formed in the first sheet member 41 and the second sheet member 42 (magnet sheet MS2A).

[0062] The two fixing holes HL are examples of marks for positioning the first sheet member 41 and the second sheet member 42, and the process of step S103 corresponds to a process of adding marks for positioning the first sheet member 41 and the second sheet member 42 to the first sheet member 41 and the second sheet member 42 while the first sheet member 41 and the second sheet member 42 are superimposed on each other.

[0063] Next, the second sheet member 42 (magnet sheet MS2A) is cut by the shutter stroke (length ΔSL) to shorten it (step S103). That is, as shown in state ST14 of FIG. 8, the magnet sheet MS2A with the length SL1 is cut by the length ΔSL to create the second sheet member 42 with the length Sl2.

[0064] The shutter stroke (length ΔSL) corresponds to the number of clicks N generated by the sliding movement of the shutter 30 multiplied by twice the length of a predetermined pitch (pitch PT) (2 × pitch PT), as shown in (1) below.

[0065] Length ΔSL = Number of clicks N × 2 × Pitch PT (1)

[0066] Furthermore, after performing the process of step S103, the first sheet member 41 is fixed to the base portion 40 using the fixing holes HL, and the second sheet member 42 is fixed to the shutter 30 using the fixing holes HL.

[0067] Next, a modified method of manufacturing the first sheet member 41 and the second sheet member 42 will be described with reference to FIGS. When the first sheet member 41 and the second sheet member 42 are made (manufactured) from two very long magnet sheets, overlapping the two magnet sheets may result in the overlapping of same-pole patterns and the generation of portions that repel each other due to variations in the pitch PT (magnetization pitch) of the N pole PN and the S pole PS. In this modification, a modification in which the first sheet member 41 and the second sheet member 42 are made (manufactured) using two very long magnet sheets in this manner will be described.

[0068] FIG. 9 is a flowchart showing a modified method of manufacturing the first sheet member 41 and the second sheet member 42 in this embodiment. FIG. 10 is a diagram illustrating a modified example of the method for manufacturing the first sheet member 41 and the second sheet member 42 in this embodiment.

[0069] As shown in Fig. 9, first, two magnet sheets (MS1a, MS2a) are overlapped in a stable position and cut simultaneously to a first length (length L1) to form two magnet sheets of the first length (length L1) (step S201). That is, the two magnet sheets (MS1a, MS2a) are overlapped so that the magnetization patterns are inverted to each other, for example, as in state ST21 of Fig. 10. In this state, the two magnet sheets (MS1a, MS2a) are cut to the length L1. The length L1 is longer than the length SL1 of the first sheet member 41.

[0070] In the example shown in FIG. 10, magnet sheets (MS3-1, MS4-1), magnet sheets (MS3-2, MS4-2), and magnet sheets (MS3-3, MS4-3) are created as two magnet sheets (MS3, MS4) having a length L1.

[0071] Next, the two magnet sheets (MS3, MS4) of the first length (length L1) are cut simultaneously to the second length (length L2) while being stacked again in a stable position to form the first sheet member 41 and the second sheet member 42 (step S202). That is, as shown in state ST22 of FIG. 10, two magnet sheets (MS3, MS4), two magnet sheets (MS3-1, MS4-1), two magnet sheets (MS3-2, MS4-2), and two magnet sheets (MS3-3, MS4-3), are stacked so that the magnetization patterns are inverted patterns. In this state, the two magnet sheets (MS3, MS4) are cut to the length L2 (length SL1 of the first sheet member 41).

[0072] As a result, as shown in state ST23 in Figure 10, a first sheet member 41 and a second sheet member 42 (magnet sheet MS2A) of length L2 (length SL1 of the first sheet member 41) are created, which include a first sheet member 41-1 and a magnet sheet MS2A-1, a first sheet member 41-2 and a magnet sheet MS2A-2, and a first sheet member 41-3 and a magnet sheet MS2A-3. In addition, by performing the process of step S201 described above, the vertical repulsion that occurs when the long magnet sheets (MS1a, MS2a) are overlapped can be reduced in the next step S202.

[0073] The steps of the next steps S203 and S204 are similar to the steps S102 and S103 shown in FIG. 7 (states ST13 and ST14 in FIG. 8), and therefore will not be described here.

[0074] As described above, the shutter mechanism 10 according to the present embodiment includes the camera 20, the shutter 30, the first sheet member 41, and the second sheet member 42. The camera 20 has the light receiving unit 22 and is mounted on the first housing 101 (housing) of the notebook PC 100 (information processing device). The shutter 30 is slidable between a first position that restricts the light receiving unit 22 from receiving light and a second position that releases the restriction on the light receiving. The first sheet member 41 is a sheet-like magnetic sheet fixed relatively to the first housing 101 (housing), and a plurality of N poles PN and S poles PS are alternately arranged at a predetermined pitch (pitch PT) in the sliding movement direction (X direction). The second sheet member 42 is a sheet-like magnetic sheet fixed relatively to the shutter 30 so that the magnetized surface of the sheet faces the magnetized surface of the first sheet member 41. In the second sheet member 42, at the first position (position where the camera 20 is permitted to be used) and the second position (position where the camera 20 is prohibited to be used), the magnetization pattern of the N poles PN and S poles PS on the magnetized surface is reversed to that of the first sheet member 41, and the N poles PN and S poles PS are alternately arranged in a plurality at a predetermined pitch (pitch PT) in the sliding movement direction. That is, in the second sheet member 42, the N poles and S poles are alternately arranged in a plurality at a predetermined pitch in the sliding movement direction, and at the first position and the second position, the magnetization pattern of the N poles and S poles on the magnetized surface is reversed to the magnetization pattern of the first sheet member 41 when viewed from the direction facing the first sheet member 41.

[0075] As a result, in the shutter mechanism 10 according to this embodiment, when the second sheet member 42 fixed relatively to the shutter 30 slides, a repulsive force (repulsion force) is generated at a position where the magnetization patterns of the first sheet member 41 and the second sheet member 42 match, and an attractive force (attraction force) is generated at a position where the magnetization patterns of the first sheet member 41 and the second sheet member 42 are reversed. Therefore, when moving from a position where the magnetization patterns match to a position where the magnetization patterns are reversed, the sliding movement is quick and weak, and when moving from a position where the magnetization patterns are reversed to a position where the magnetization patterns match, a strong resistance force is generated, making the sliding movement difficult. As a result, the shutter mechanism 10 according to this embodiment can generate a clicking sensation by the sliding movement of the shutter 30.

[0076] Furthermore, in the shutter mechanism 10 of this embodiment, the magnetization patterns of the first sheet member 41 and the second sheet member 42 are reversed in the first position (position where camera 20 is permitted to be used) and the second position (position where camera 20 is prohibited to be used), so that the shutter 30 will not move inadvertently due to gravity, vibration, or the like.

[0077] In addition, the shutter mechanism 10 according to this embodiment does not require an elastic body such as a leaf spring or a protrusion for generating a clicking sensation, so the configuration can be simplified and the mechanism can be made compact. Therefore, the shutter mechanism 10 according to this embodiment can be made compact while generating an appropriate clicking sensation by the movement of the shutter 30.

[0078] For example, in the shutter mechanism 10 of this embodiment, by using a magnetic sheet, it can be stored on the camera board PB, and the size of the bezel 105 in the short side direction (Y direction) can be shortened, and the size of the first housing 101 in the thickness direction (Z direction) can be shortened.

[0079] In this embodiment, the length SL2 of the second sheet member 42 in the sliding movement direction is shorter than the length SL1 of the first sheet member 41 in the sliding movement direction by the amount by which the shutter 30 can move (length ΔSL).

[0080] As a result, the shutter mechanism 10 of this embodiment can appropriately set the amount of movement of the shutter 30, and can also appropriately set the first position (position where camera 20 is permitted to be used) and the second position (position where camera 20 is prohibited to be used).

[0081] Furthermore, in this embodiment, the length SL2 of the second sheet member 42 in the sliding movement direction is configured to be shorter than the length SL1 of the first sheet member 41 in the sliding movement direction by the number N of click sensations generated by the sliding movement of the shutter 30 multiplied by twice the length of a predetermined pitch (pitch PT) (2 x pitch PT) (see formula (1) above).

[0082] As a result, the shutter mechanism 10 according to the present embodiment can generate an appropriate number of clicking sensations when the shutter 30 is slid.

[0083] Moreover, the notebook PC 100 (information processing device) according to this embodiment includes the above-mentioned shutter mechanism 10 and a first housing 101 in which the shutter mechanism 10 is mounted. As a result, the notebook PC 100 (information processing device) according to this embodiment can have a smaller shutter mechanism 10, and thus can be made smaller and lighter by incorporating the shutter mechanism 10.

[0084] In this embodiment, the first housing 101 is equipped with a display unit 104. The shutter mechanism 10 is disposed in a bezel 105 portion that is provided on the first housing 101 to surround the display unit 104.

[0085] As a result, in the notebook PC 100 according to this embodiment, the size of the bezel 105 in the short side direction (Y direction) can be shortened, and the size of the first housing 101 in the thickness direction (Z direction) can be shortened. Therefore, in the notebook PC 100 according to this embodiment, the size of the display unit 104 can be increased. Also, in the notebook PC 100 according to this embodiment, since the size of the first housing 101 in the thickness direction can be reduced, the first housing 101 can be made smaller and thinner.

[0086] The manufacturing method of the shutter mechanism 10 according to this embodiment includes a first step (step S101 in FIG. 7), a second step (step S102 in FIG. 7), and a third step (step S103 in FIG. 7). The shutter mechanism 10 includes the above-mentioned shutter 30, a first sheet member 41, and a second sheet member 42. The first step is a step of overlapping two magnet sheets (MS1, MS2) with their magnetized surfaces facing each other in a position where the N pole PN and the S pole PS are inverted and stable, and cutting out the first sheet member 41 and the second sheet member 42 (magnet sheet MS2A) from the two magnet sheets (MS1, MS2). The second step is a step of adding marks for positioning the first sheet member 41 and the second sheet member 42 (magnet sheet MS2A) to the first sheet member 41 and the second sheet member 42 (magnet sheet MS2A) in a state where the first sheet member 41 and the second sheet member 42 (magnet sheet MS2A) are overlapped. The third step is a step of cutting the second sheet member 42 shorter by an amount sufficient to allow the shutter 30 to move.

[0087] As a result, the manufacturing method for the shutter mechanism 10 according to the present embodiment can manufacture an appropriate first sheet member 41 and second sheet member 42, and can reduce the size of the shutter mechanism 10 and the notebook PC 100.

[0088] In this embodiment, the positioning marks are fixing holes HL for fixing the first sheet member 41 and the second sheet member 42. The second step is a step of forming fixing holes HL for fixing the first sheet member 41 and the second sheet member 42 (magnet sheet MS2A) in a superimposed state.

[0089] Thereby, in the manufacturing method of the shutter mechanism 10 according to the present embodiment, by forming the fixing holes HL, the first sheet member 41 and the second sheet member 42 can be fixed in an appropriate positional relationship.

[0090] In addition, in this embodiment, the first process (steps S201 and S202 in FIG. 10) is a process of cutting two magnet sheets (MS1a, MS2a) in an overlapping state to a first length L1 in the slide movement direction, and then cutting the two cut magnet sheets of the first length L1 to a second length L2 (SL1) shorter than the first length L1 while overlapping them in a position where the magnetized surfaces face each other and the N pole PN and the S pole PS are inverted and stable, to cut out the first sheet member 41 and the second sheet member 42 (magnet sheet MS2A).

[0091] As a result, the manufacturing method of the shutter mechanism 10 according to this embodiment can manufacture appropriate first sheet members 41 and second sheet members 42, even when, for example, the first sheet member 41 and the second sheet member 42 are manufactured from two very long magnet sheets (MS1a, MS2a) and variation in pitch PT (magnetization pitch) becomes a problem, and the shutter mechanism 10 and the notebook PC 100 can be made smaller.

[0092] The present invention is not limited to the above-described embodiment, and can be modified without departing from the spirit of the present invention. For example, in the above embodiment, an example was described in which the information processing device was a notebook PC 100, but this is not limited to this, and the information processing device may be, for example, another information processing device such as a tablet terminal device, a smartphone, or an electronic device equipped with a camera.

[0093] In addition, in the above embodiment, an example has been described in which the shutter mechanism 10 is mounted in the bezel 105 portion of the first housing 101 having the display unit 104, but this is not limited to this, and the shutter mechanism 10 may be mounted in other housings (locations), such as a housing that does not have the display unit 104 or a portion other than the bezel 105.

[0094] In the above embodiment, an example has been described in which camera 20 using shutter mechanism 10 includes indicator lamp 21, visible light receiving unit 22 (visible light camera), infrared light receiving unit 23 (infrared camera), and infrared light emitting unit 24, but the present invention is not limited to this and may be a camera with another configuration. For example, camera 20 may be configured without including some of the components of indicator lamp 21, visible light receiving unit 22 (visible light camera), infrared light receiving unit 23 (infrared camera), and infrared light emitting unit 24.

[0095] In the above embodiment, the fixing holes HL are used as an example of the positioning marks, but the present invention is not limited to this and may be other marks such as marks. The positioning marks may also be added by other processing such as printing.

[0096] Furthermore, the number of magnetization patterns (the number of magnetic pole patterns) of the first sheet member 41 and the second sheet member 42 is not limited to that in the above embodiment, and may be changed depending on the information processing device to be used.
