  As described above, the protruding piece member moves between the first position and the second position. Therefore, the projecting piece member and the display housing often come into contact with each other when the projecting piece member moves. As a result, for example, a linear mark is formed on the surface of the protruding piece member. Such a linear mark deteriorates the appearance of the protruding piece member.

  The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a housing unit and an electronic apparatus that can avoid deterioration of the appearance of the protruding piece member.

  In order to achieve the above object, according to the first invention, from the first position, the housing, a first position that is guided along a straight line on the housing and projects one end from the surface of the housing, and And a projecting piece member that moves between a second position in which one end is retracted in the housing, and a surface of the projecting piece member is formed with a stripe pattern parallel to the one straight line. Provided.

  In such a casing unit, the protruding piece member is guided along a straight line on the casing. Thus, the protruding piece member moves between the first position and the second position. A striped pattern is formed on the surface of the projecting piece member along the one straight line. Therefore, even if a linear trace is formed on the surface of the protruding piece member based on contact between the protruding piece member and the housing during the movement of the protruding piece member, the linear trace is in the same direction as the striped pattern along one straight line. Formed. The line marks are inconspicuous due to the striped pattern. Deterioration of the appearance of the protruding piece member can be avoided.

  Such a housing unit is incorporated in the housing to guide the movement of the projecting piece member, a projection formed on the guide member, facing the projecting piece member, and formed on the projecting piece member. You may further provide the 1st hollow which receives protrusion on the protruding piece member of 1 position, and the 2nd hollow formed in the protruding piece member and receiving protrusion on the protruding piece member of 2nd position. Thus, the movement of the protruding piece member is guided by the guide member. Even if a linear mark is formed on the surface of the protruding piece member, for example, based on contact between the protruding piece member and the guide member during the movement of the protruding piece member, the linear mark is not conspicuous due to the stripe pattern. Deterioration of the appearance of the protruding piece member can be avoided.

  According to the second invention, the first housing, the second housing that rotates relative to the first housing around the first axis and faces the surface of the first housing on the surface, and the second housing And a projecting piece member that moves between a first position where one end protrudes from the surface of the second casing and a second position where one end retracts from the first position into the second casing. And a receiving hole that is partitioned on the surface of the first housing and receives the entry of one end of the projecting piece member when the second housing is positioned at a specific position around the first axis, the surface of the projecting piece member Is provided with a striped pattern parallel to the one straight line.

  In such an electronic device, the protruding piece member moves between the first position and the second position along a straight line on the second housing. A striped pattern is formed on the surface of the projecting piece member along the one straight line. Similarly to the above, even if a linear trace is formed on the surface of the protruding piece member, for example, based on contact between the protruding piece member and the housing during the movement of the protruding piece member, the linear trace is a striped pattern along one straight line. They are formed in the same direction. Similarly, for example, even if a linear mark is formed on the surface of the protruding piece member based on the contact between the protruding piece member and the receiving hole, the linear mark is formed in the same direction as the striped pattern along one straight line. These line marks are inconspicuous due to the striped pattern. Deterioration of the appearance of the protruding piece member can be avoided.

  Such an electronic device is incorporated in the second housing to guide the movement of the protruding piece member, the protrusion formed on the guiding member and facing the protruding piece member, and the protruding piece member, You may further provide the 1st hollow which receives protrusion on the protruding piece member of a 1st position, and the 2nd hollow formed in the protruding piece member and receiving protrusion on the protruding piece member of a 2nd position. Thus, the movement of the protruding piece member is guided by the guide member. Even if a linear mark is formed on the surface of the protruding piece member, for example, based on contact between the protruding piece member and the guide member during the movement of the protruding piece member, the linear mark is not conspicuous due to the stripe pattern. Deterioration of the appearance of the protruding piece member can be avoided.

  A component unit is provided for realizing the above-described housing unit and electronic device. The component unit may include a slide member, a first position defined on one straight line, and a guide member that guides the movement of the slide member between a second position different from the first position. At this time, a striped pattern may be formed on the surface of the slide member in parallel with the one straight line. The striped pattern may be defined based on a groove and a protruding wall formed in parallel with each other on the surface of the slide member.

  As described above, according to the present invention, it is possible to provide a housing unit and an electronic apparatus that can avoid the deterioration of the appearance of the protruding piece member.

  Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings.

  FIG. 1 schematically shows an external appearance of an electronic apparatus, that is, a notebook personal computer (hereinafter “notebook personal computer”) 11 according to an embodiment of the present invention. The notebook computer 11 includes a first housing, that is, a main body housing 12, and a second housing, that is, a display housing 13 connected to the main body housing 12. The main body housing 12 and the display housing 13 may be made of a reinforced resin material such as polycarbonate.

  For example, a motherboard is incorporated in the main body housing 12. Electronic circuit elements such as a CPU (Central Processing Unit) and a memory are mounted on the motherboard. The CPU executes various arithmetic processes based on, for example, software programs and data temporarily stored in the memory. Similarly, the software program and data may be stored in a mass storage device such as a hard disk drive (HDD) housed in the main body housing 12.

  Input devices such as a keyboard 14 and input buttons 15 are incorporated in the main body housing 12. With these functions of the input devices 14 and 15, the user of the notebook personal computer 11 can input various commands and data to the CPU.

  A flat display panel such as a liquid crystal display (LCD) panel 16 is accommodated in the display housing 13. The display housing 13 exposes the screen of the LCD panel 16 on the surface. Various texts and graphics can be displayed on the screen of the LCD panel 16 based on arithmetic processing of the CPU.

  An input device such as a touch panel 17 is disposed on the surface of the LCD panel 16. For example, various commands and data can be input from the touch panel 17 to the CPU based on the operation of the stylus pen.

  The main housing 12 and the display housing 13 are connected to each other by a biaxial rotation mechanism 21 (hereinafter referred to as “rotation mechanism”). The rotation mechanism 21 realizes rotation around the first axis, that is, the horizontal axis 22, and rotation around the second axis, that is, the vertical axis 23, between the main body casing 12 and the display casing 13. Here, the horizontal axis 22 may be defined parallel to the surface at one end of the surface of the main body housing 12. The vertical axis 23 is defined in one plane orthogonal to the horizontal axis 22. The vertical axis 23 is orthogonal to the surface of the main body housing 12.

  For example, a flat slide member, that is, a projecting piece member 25 is incorporated in the display housing 13. One end of the protruding piece member 25 protrudes from the surface of the display housing 13. The protruding piece member 25 is disposed at a predetermined position with respect to the horizontal shaft 22. On the other hand, a receiving hole 26 is defined on the surface of the main body housing 12. The receiving hole 26 is disposed at a predetermined position with respect to the vertical axis 23. Here, the protruding piece member 25 and the receiving hole 26 function as a fixing structure of the notebook computer 11.

  Now, it is assumed that the surface of the display housing 13 is superposed on the surface of the main body housing 12 based on the relative rotation around the horizontal axis 22. As shown in FIG. 1, the display housing 13 is positioned at a specific position around the vertical axis 23. When this specific position is established, a positional relationship reflecting the positional relationship between the horizontal shaft 22 and the projecting piece member 25 is established between the receiving hole 26 and the horizontal shaft 22.

  At this specific position, for example, as shown in FIG. 2, the display housing 13 can be superimposed on the main body housing 12 around the horizontal axis 22. The first posture of the display housing 13 is established. The surface of the display housing 13 faces the surface of the main body housing 12. Here, since a specific position is established around the vertical axis 23, the outline of the display housing 13 overlaps the outline of the main body housing 12. In this way, the notebook computer 11 is folded.

  The rotation mechanism 21 exerts a pressing force that presses the display housing 13 toward the surface of the main body housing 12. As a result, relative rotation of the display housing 13 around the horizontal axis 22 with respect to the main body housing 12 is restricted. Details of the rotating mechanism 21 will be described later. At this time, the receiving hole 26 receives the entrance of one end of the protruding piece member 25 protruding from the surface of the display housing 13. Therefore, even if an external force is applied to the display housing 13 around the vertical axis 23, relative rotation of the display housing 13 around the vertical axis 23 with respect to the main body housing 12 is restricted. The first posture of the display housing 13 is maintained.

  For example, as shown in FIG. 3, the display housing 13 can rotate relative to the main body housing 12 around the vertical axis 23 at a relative rotation angle of, for example, 180 degrees. Thus, the display housing 13 is positioned at a specific position around the vertical axis 23. When this specific position is established, a positional relationship reflecting the positional relationship between the horizontal shaft 22 and the projecting piece member 25 is established between the receiving hole 26 and the horizontal shaft 22 as described above.

  At this specific position, for example, as shown in FIG. 4, the display housing 13 can be superimposed on the main body housing 12 around the horizontal axis 22. The second posture of the display housing 13 is established. The back surface of the display housing 13 faces the front surface of the main body housing 12. In this way, the notebook computer 11 is folded.

  The rotating mechanism 21 exerts a pressing force that presses the display housing 13 toward the surface of the main body housing 12 as described above. As a result, relative rotation of the display housing 13 around the horizontal axis 22 with respect to the main body housing 12 is restricted. At this time, the receiving hole 26 receives the entry of the other end of the protruding piece member 25 protruding from the back surface of the display housing 13. Therefore, the relative rotation of the display housing 13 around the vertical axis 23 is restricted. The second posture of the display housing 13 is maintained.

  As shown in FIG. 5, the protruding piece member 25 is supported by the guide member 27. The guide member 27 guides the movement of the protruding piece member 25 along one straight line. The moving direction of the projecting piece member 25 may be orthogonal to the surface of the main body housing 12 when the first posture or the second posture is established in the display housing 13. The guide member 27 is fixed to the display housing 13. For example, a screw 28 is used for fixing. The screw 28 may be received by a boss rising from the inner wall surface of the display housing 13. Here, the projecting piece member 25 and the guide member 27 constitute a component unit of the present invention. The projecting piece member 25 and the display housing 13 constitute a housing unit of the present invention.

  The rotation mechanism 21 includes a bearing 31 and a support shaft 32 that is rotatably supported by the bearing 31 around the vertical shaft 23. The bearing 31 is fixed to, for example, the inner wall surface of the main body housing 12. For example, a screw 33 is used to fix the bearing 31. The screw 33 may be received by a boss standing upright from the inner wall surface of the main body housing 12. The axis of the support shaft 32 coincides with the vertical axis 23. For example, a decorative cover 34 covers the support shaft 32.

  A pair of shaft members 35 and 35 extending in opposite directions are integrated with the support shaft 32. The axis of the shaft members 35, 35 coincides with the horizontal axis 22. A connecting piece 36 is connected to the tip of the shaft member 35 so as to be rotatable around the axis of the shaft member 35. The connecting piece 36 is fixed to the inner wall surface of the display housing 13. For example, a screw 37 is used for fixing. The screw 37 may be received by a boss standing upright from the inner wall surface of the display housing 13. Here, the support shaft 32 and the shaft member 35 may be integrally formed from a metal material such as stainless steel.

  Based on the rotation mechanism 21, the main body housing 12 and the display housing 13 are connected. As a result, when the connecting piece 36 rotates relative to the shaft member 35, relative rotation around the horizontal axis 22 of the display housing 13 with respect to the main body housing 12 can be realized. On the other hand, when the connecting piece 36 rotates relative to the bearing 31 around the axis of the support shaft 32, relative rotation around the vertical axis 23 of the display housing 13 is realized with respect to the main body housing 12. Can do.

  As shown in FIG. 6, the connecting piece 36 is connected to the shaft 35 a of the shaft member 35 by the annular portion 38. The annular portion 38 can rotate around the axis of the shaft member 35. An annular member 39 supported by the shaft 35 a is disposed outside the annular portion 38. An elastic member, that is, a spring 41, which is similarly supported by the shaft 35a, is disposed outside the annular member 39.

  A fastener 42 fixed to the shaft 35 a is disposed outside the spring 41. Based on the fastener 42, the annular portion 38, the annular member 39, and the spring 41 are held by the shaft 35a. The rotation of the annular member 39 and the spring 41 is restricted around the axis of the shaft member 35. On the other hand, the annular member 39 can move in the axial direction of the shaft member 35 based on the expansion and contraction of the spring 41.

  The inner end surface of the annular member 39 faces the outer end surface of the annular portion 38. A cam surface 38 a is formed on the outer end surface of the annular portion 38. On the other hand, a protrusion 39 a is formed on the inner end surface of the annular member 39. The shape of the inner end surface of the annular member 39 matches the shape of the outer end surface of the annular portion 38. Since the rotation of the annular member 39 is restricted, the annular portion 38 can rotate relative to the annular member 39. Thus, the protrusion 39a and the cam surface 38a constitute a cam mechanism.

  When the connecting piece 36, that is, the annular portion 38 rotates, the annular portion 38 and the annular member 39 rotate relative to each other as shown in FIG. The annular member 39 is pressed against the annular portion 38 by the action of the spring 41. When the annular portion 38 further rotates, the protrusion 39a is pressed against the cam surface 38a as shown in FIG. In this way, the pressing force of the protrusion 39a is converted into the driving force for rotation of the annular portion 38. As a result, the aforementioned pressing force is applied to the display housing 13 toward the main body housing 12.

  FIG. 9 schematically shows the structure of the projecting piece member 25 and the guide member 27. The guide member 27 includes a receiving member 27a that supports the protruding piece member 25, and a pair of flat plate members 27b and 27b that extend in the opposite directions from the receiving member 27a. The receiving member 27a defines an internal space of a rectangular parallelepiped. The receiving member 27a and the flat plate member 27b may be formed based on, for example, integral molding. A through hole 45 for receiving the screw 28 is formed in the flat plate member 27b. The protruding piece member 25 and the guide member 27 may be made of, for example, a synthetic resin material.

  A guide protrusion 46 is formed on the back surface of the protruding piece member 25. The guide protrusion 46 is received in a guide groove 47 formed on the inner wall surface of the receiving member 27a. The guide groove 47 is formed over the entire length of the receiving member 27a along the moving direction of the projecting piece member 25, that is, along the aforementioned one straight line. Thus, the guide member 27 can guide the movement of the protruding piece member 25 along one straight line based on the guide protrusion 46 and the guide groove 47. A striped pattern 48 is formed on the front and back surfaces of the projecting piece member 25 in parallel to the above-described straight line. Details of the stripe pattern will be described later.

  Referring also to FIG. 10, the projecting piece member 25 is defined with a pair of first contour lines 51, 51 that partition the outer shape of the projecting piece member 25 between one end and the other end. The first contour line 51 is defined in parallel with the vertical axis 23 in the display housing 13 in the first posture. The projecting piece member 25 is defined with a pair of second contour lines 52, 52 set in parallel to the horizontal axis 22. The second contour line 52 defines one end and the other end of the protruding piece member 25.

  The first and second contour lines 51 and 52 are connected by a third contour line 53. In this way, so-called chamfering is realized on the projecting piece member 25. Here, the first and second contour lines 51 and 52 may be defined by straight lines, for example. Similarly, the third contour line 53 may be defined by a straight line, for example. In addition, the third contour line 53 may be defined by a curved line, for example.

  A pair of protrusions 54, 54 are formed between the one end and the other end on the side surface of the protrusion piece member 25. On the other hand, a protruding wall 55 protruding toward the protruding piece member 25 is formed at one end of the receiving member 27a. When the protruding piece member 25 is positioned at the first position, the protruding portion 54 is received by the protruding wall 55. In this way, it is possible to prevent the protruding piece member 25 from coming off from the receiving member 27a.

  On the other hand, the other end of the receiving member 27 a is received by the inner wall surface of the display housing 13. When the protruding piece member 25 is positioned at the second position, the protruding portion 54 is received by the inner wall surface of the display housing 13. In this way, it is possible to prevent the protruding piece member 25 from coming off from the receiving member 27a.

  As shown in FIG. 11, a first dent 61 and a second dent 62 are formed on the front and back surfaces of the protruding piece member 25. A third recess 63 is formed between the first and second recesses 61 and 62. The first and second depressions 61 and 62 and the third depression 63 are arranged on one straight line. The first to third recesses 61, 62, 63 are recessed in a hemispherical shape.

  Connection grooves 64 and 64 that connect the first recess 61 and the third recess 63 and the second recess 62 and the third recess 63 are further formed on the front and back surfaces of the protruding piece member 25. The depth from the surface of the projecting piece member 25 may be set larger in the first to third recesses 61, 62, 63 than the connection groove 64. The aforementioned stripe pattern 48 extends from one end of the projecting piece member 25 to the other end.

  As shown in FIG. 12, a pair of protrusions 65 are formed on the inner wall surface of the receiving member 27 a so as to face the front and back surfaces of the protruding piece member 25. The protrusion 65 swells in a hemispherical shape, for example. The first recess 61 receives the protrusion 65 on the protruding piece member 25 in the first position. The second recess 62 receives the protrusion 65 on the protruding piece member 25 in the second position. Thus, the movement path of the protrusion 65 is defined by the first to third recesses 61, 62, 63 and the connection groove 64.

  When the protruding piece member 25 is disposed at the first position, the protrusion 65 is received in the first recess 61. When the projecting piece member 25 moves from the first position toward the second position, the projecting piece member 25 retracts one end. At this time, the protrusion 65 is received in the first recess 61, the third recess 63, and the second recess 62 in order. At this time, the protrusion 65 is received in the third recess 63. As a result, even if a relatively large distance is set between the first and second recesses 61 and 62, the protrusion 65 and the protruding piece member 25 can be prevented from being deformed as much as possible.

  Moreover, when the protrusion 65 is received in the third recess 63, the protruding piece member 25 is held at a position between the first position and the second position. Thus, for example, the projecting piece member 25 can project one end and the other end simultaneously from the front surface and the back surface of the display housing 13. That is, in the protruding piece member 25, the length from one end to the other end may be set to a length that allows the one end and the other end to protrude simultaneously from the front and back surfaces of the display housing 13.

  As shown in FIG. 13, the striped pattern 48 is partitioned from grooves 48 a and protruding walls 48 b formed on the front and back surfaces of the protruding piece member 25. The groove 48a and the projecting wall 48b extend in parallel to the above-mentioned straight line. That is, the groove 48a and the protruding wall 48b extend in parallel to each other. The interval between the grooves 48a and the interval between the protruding walls 48b may be set to about 1 to 2 mm, for example. Such a projecting piece member 25 is formed based on molding, for example. The striped pattern 48 may be formed based on molding.

  In such a notebook computer 11, the striped pattern 48 is formed in parallel with one straight line. The movement of the projecting piece member 25 along one straight line by the action of the stripe pattern 48 is based on the contact of the projecting piece member 25 and the display housing 13 and the contact of the projecting piece member 25 and the guide member 27. Even if linear traces are formed on the front and back surfaces, the linear traces are not noticeable. Deterioration of the appearance of the front and back surfaces of the projecting piece member 25 is avoided.

  Moreover, the projecting piece member 25 contacts the guide member 27 and the display housing 13 at the top of the projecting wall 48b. Compared to the case where the front and back surfaces of the projecting piece member 25 are formed as flat surfaces, the contact area between the projecting piece member 25 and the guide member 27 and the display housing 13 is significantly reduced. As a result, the frictional force is reduced between the projecting piece member 25 and the guide member 27 or the display housing 13. Formation of linear traces on the front and back surfaces of the projecting piece member 25 is avoided as much as possible.

  During molding of the projecting piece member 25, for example, a trace of a knock pin remains on the back surface of the projecting piece member 25. When the protruding piece member 25 is incorporated into the guide member 27, the protruding piece member 25 is incorporated into the guide member 27 based on the alignment of the guide protrusion 46 and the guide groove 47. As a result, the protruding piece member 25 can be received by the guide member 27 only in a predetermined direction. If the back surface of the projecting piece member 25 is directed to the opposite side from the user's eyes, the trace of the knock pin is hidden. Deterioration of the appearance of the projecting piece member 25 can be avoided.

  In the notebook personal computer 11 as described above, prior to folding, for example, it is assumed that the display housing 13 is displaced from the main body housing 12 around the vertical axis 23 from a specific position. At this time, when the display housing 13 rotates relative to the main body housing 12 around the horizontal axis 22, one end of the projecting piece member 25 contacts the surface of the main body housing 12. At this time, as shown in FIG. 14, for example, the protruding piece member 25 can move from the first position toward the second position based on the contact. Damage or breakage on the surface of the main body housing 12 can be avoided. For example, when the other end of the projecting piece member 25 contacts the surface of the main body housing 12, the projecting piece member 25 can move from the second position toward the first position based on the contact. Damage or breakage on the surface of the main body housing 12 can be avoided.

  In addition, the projecting piece member 25 is chamfered. Therefore, even if the display housing 13 is displaced from the specific position around the vertical shaft 23 with respect to the main body housing 12, for example, as shown in FIG. 26 openings can be received. Based on such chamfering, one end and the other end of the projecting piece member 25 can be guided to the receiving hole 26 relatively easily.

  Further, when the display housing 13 is frequently folded by changing the front and back surfaces, the projecting piece member 25 can be held with one end and the other end projecting simultaneously from the front and back surfaces of the display housing 13. Good. At this time, the protrusion 65 may be received in the third recess 63 as described above. Thus, when the notebook personal computer 11 is folded, the work of adjusting the position of the protruding piece member 25 is not required.

  In addition to the notebook computer 11, the electronic device of the present invention can include other electronic devices such as a mobile phone terminal device and a personal digital assistant (PDA).
