Description

  The present invention relates to a rotary hinge and an information device using the rotary hinge. In particular, the present invention relates to a rotating hinge that can rotate 90 degrees clockwise and / or counterclockwise, and an information device that can rotate a display screen 90 degrees clockwise and / or counterclockwise using such a rotating hinge.

  The spread of information equipment, especially mobile phones, is remarkable. Many mobile phones have a vertically long rectangular shape for easy operation with one hand, and a folding hinge is placed between the control and display for ease of carrying. The structure can be folded in half (clam shell structure). In this case, the shape of the operation unit and the shape of the display unit are substantially the same so that the ends of the operation unit and the display unit are aligned when folded in half. For this reason, in many mobile phones, the display unit is usually used in a vertically long state.

  However, various functions have been installed in mobile phones, and in some cases it is preferable to set the display unit in a horizontally long state rather than in a vertically long state. For example, when a television broadcast is received and an image is displayed, if the display unit is in a horizontally long state, the entire display unit can be used for displaying an image, and an easily viewable display can be performed.

  For this reason, there has been provided a mobile phone having a display unit that can rotate the display unit by 90 degrees while maintaining the operation unit in a vertically long state (see, for example, Patent Document 1). That is, in such a mobile phone, when the display unit is a movable case, connected to the operation unit via a rotary hinge, and the holding unit that holds the display unit is a holding base, a plate cam is attached to the movable case. The plate cam is provided with a first protrusion and a second protrusion. In the holding base, a first passage in the vertical direction in which the first protrusion moves, a second passage in the vertical direction in which the second protrusion moves, and the first protrusion and the second protrusion are movable. A common passage connecting the second passage is provided. Then, the second protrusion moves the common passage toward the first passage, the first protrusion moves up the first passage, or the first protrusion moves the common passage toward the second passage, and the second protrusion Moves up the second passage so that the movable housing can be rotated 90 degrees clockwise and counterclockwise.

  In addition, in other information devices such as a display device that can be connected to a personal computer, the display unit can be rotated by 90 degrees and set to either a vertically long state or a horizontally long state as necessary. Something is also known.

JP 2008-121751 A

  As one of the preferable conditions of the rotating hinge for enabling the display unit to rotate 90 degrees in this way, first, it should be mentioned that a smooth rotation operation of the display unit should be provided. In the technique disclosed in Patent Document 1, since the locking projection and the engagement recess are formed, an operation of fitting the first projection and the second projection into the locking projection and the engagement recess is necessary. Providing smooth rotation is difficult. In addition, when the common passage extends horizontally, the display unit rotates around the first protrusion or the second protrusion while the first protrusion or the second protrusion is present in the common passage. Therefore, it is difficult to provide a smooth rotation operation.

  Another condition is that the width of the rotating hinge should be reduced so that the portion of the rotating mechanism having the rotating hinge cannot be seen while the display unit is rotating. In the technique disclosed in Patent Document 1, even if the common passage portion is bent upward, there is a portion that extends horizontally, so it is difficult to reduce the width of the rotary hinge.

  Another condition is that the display unit is as symmetrical as possible with respect to the operation unit before and after the display unit is rotated 90 degrees clockwise or counterclockwise. It is done. In other words, the symmetry line of the display part before rotation and the symmetry line of the display part after rotation are substantially the same. In the technique disclosed in Patent Document 1, for example, as shown in FIG. 13, when the display unit is rotated 90 degrees counterclockwise, the display unit is moved to the left with respect to the operation unit. Symmetry is not maintained and the aesthetics are impaired.

  In the first aspect of the present invention, a plate in which two slits cross at a crossing point, a first protrusion movable in the first slit which is one of the two slits, and the There is provided a rotary hinge having a connecting portion that connects a second protrusion that is movable in a second slit, which is the other of the two slits. The first protrusion moves in the first slit in one direction through the intersection of the two slits, and at the same time, the second protrusion moves away from the intersection in the second slit and then approaches. It is possible to reciprocate. Thereby, it becomes possible to rotate a connection part smoothly and a subject is solved. Further, the rotary hinge can be reduced in size by reciprocating the second protrusion.

  In addition, the second protrusion moves in the second slit in one direction through the intersection of the two slits, and at the same time, the first protrusion moves away from the intersection in the first slit and then approaches. It is possible to reciprocate. Therefore, the connecting portion can be rotated in the clockwise direction or in the opposite direction.

  In the second aspect of the present invention, in the first aspect described above, each of the first slit and the second slit is between one end of the two ends and the crossing point. A rotating hinge having a first bent portion and a second bent portion between the first bent portion and the crossing portion is provided. Each of the first protrusion and the second protrusion can be positioned at the first bent portion of the first slit and the first bent portion of the second slit. From this state, the first protrusion moves toward the second bent portion of the first slit and the second protrusion moves toward the end of the second slit. Further, the first protrusion passes from the second bent portion of the first slit through the crossing portion and approaches the end opposite to the end of the first slit, and the second protrusion extends from the end of the second slit. Move to the first bend. Thereby, a connection part rotates. Accordingly, when the first protrusion moves toward the second bent portion of the first slit and the second protrusion moves toward the end of the second slit, the first protrusion moves upward while rotating the connecting portion. When a display unit or an operation unit of an information device such as a mobile phone is fixed to the connection unit, the center of the display unit can be rotated while being temporarily separated from the rotary hinge. So the problem is solved.

  In the third aspect of the present invention, in any one of the above aspects, the first protrusion moves in the first slit through the crossing point in one direction while the second protrusion is the second. A revolving hinge is provided in which the connecting portion rotates 90 degrees when reciprocating in the slit. Thereby, in an information device such as a mobile phone, the display unit and the operation unit can be rotated 90 degrees, and the problem is solved. Moreover, by making the shape of the two slits bilaterally symmetric, the display unit can be bilaterally symmetric with respect to substantially the same vertical line before and after being rotated 90 degrees.

  Moreover, in the 4th side surface of this invention, in any one of said 1st to 3rd side | surfaces, when the 1st protrusion reaches | attains a crossing location, it prevents from approaching into a 2nd slit A rotating hinge with blocking means is provided. This ensures that the first protrusion moves in the first slit.

  Further, the entry preventing means has a guide portion formed as a region protruding on the plate, and a third protrusion is formed on the connecting portion. When the first protrusion reaches the crossing point, the guide portion is formed. The first projecting portion of the part and the third projection may approach, contact, and abut, and the first projection may be prevented from entering the second slit.

  Further, when the rotation of the connecting portion approaches 90 degrees, the guide portion may have a shape in which the third protrusion is located on the opposite side of the crossing location of the guide portion. In other words, when the connecting portion tries to rotate more than 90 degrees, the third protrusion may approach, contact, or abut against the guide portion. Thereby, it can prevent that a connection part rotates exceeding 90 degree | times. As a result, damage to the information device can be prevented.

  The second protrusion may be biased by applying a force directed to the first bent portion of the second slit. Thereby, the mechanical energy in the case where the second protrusion is located at the first bent portion of the second slit can be minimized, and a stable state can be realized.

  The biasing means is configured such that a lever connected to an elastic body having one end connected to the plate comes into contact with the second protrusion to apply a force toward the first bent portion of the second slit. May be.

  Further, the upper side of the lever may be located below the upper side of the plate while the second protrusion moves in the second slit. Thereby, since the lever is not located on the upper part of the plate, it is not necessary to provide a space above the rotary hinge, and downsizing of the apparatus using the rotary hinge can be realized.

  In addition, the plate may have two side edges and an upper side having a recess that is recessed between the two side edges and is above the intersection of the slits. A cable or the like for transmitting a signal of an information device can be arranged using the recess.

  The lever includes a first portion and a second portion parallel to the two sides of the plate, and a third portion connecting the first portion and the second portion. One part or the second part may contact the second protrusion. Thereby, the elastic body which generates the force applied to the second protrusion can be divided into two, and the size can be reduced.

The third portion connects the upper portions of the first portion and the second portion. Alternatively, the third part connects the lower part of the first part and the second part. In particular, when the third part connects the lower part of the first part and the second part, when the rotary hinge is used for the rotation of the display part of the information device, the signal is transmitted to and received from the display part. Can be prevented from contacting the lever, and the occurrence of cable damage can be suppressed.

  Moreover, in the 5th side surface of this invention, the information equipment using said rotation hinge is provided. For example, an information device in which an operation unit such as a keyboard and a joystick, a display unit housing including a display unit, and the like are provided in the main body via a rotary hinge. And the operation part and the display part housing | casing have the attachment part arrange | positioned at the back surface etc. fixed to the said connection part. As described above, the first protrusion of the rotary hinge moves in one direction through the crossing point in the first slit, and the second protrusion approaches after moving away from the crossing point in the second slit. By reciprocating, the operation unit, the display unit housing, and the like can be rotated 90 degrees in the clockwise direction and in the opposite direction.

  In the information device according to the fifth aspect of the present invention, each of the first slit and the second slit has a first bent portion and a first bent portion between one end and the crossing portion. A second bent portion between the first portion and the intersecting portion, and the first protrusion and the second protrusion are respectively connected to the first bent portion of the first slit and the first bent portion of the second slit. When the first protrusion moves toward the second bent portion of the first slit and the second protrusion moves toward the end of the second slit after being positioned at the bent portion, the operation unit and the display The height of the partial housing or the like when the first protrusion and the second protrusion are positioned at the first bent portion of the first slit and the first bent portion of the second slit, respectively. You may rotate while moving the above area | region. Thereby, when a display part rotates, it can prevent entering into the area | region under a display part.

  In addition, the operation unit, the display unit housing, and the like may be symmetrical with respect to substantially the same vertical line before and after rotating 90 degrees clockwise or in the opposite direction. Thereby, it can prevent that the left-right symmetry of the external shape of an information device is impaired by rotation.

  In addition, the plate of the rotary hinge has a straight side and an upper side that is recessed on the upper side of the first slit and the second slit, and is routed along the upper side from the side of the plate. In addition, the cable may be connected to the operation unit, the display unit housing, or the like through a through hole on the back surface of the operation unit, the display unit housing, or the like provided at a position above the concave portion of the plate. By positioning the through hole at the center of rotation such as the operation unit or the display unit housing, it is possible to prevent an excessive force from being applied to the cable even when it is rotated left and right.

  The upper side of the through hole may be arcuate. In this case, the rotary hinge is attached to the rear of the hinge mounting housing having the second recess between the straight sides, and the display housing is attached to the front of the hinge mounting housing. Even if the display unit casing rotates, the upper side of the through hole may be positioned below the straight line connecting the upper sides of the two straight sides of the hinge mounting casing. Thereby, when it sees from the back side, such as an operation part and a display part housing | casing, a through-hole can be seen and it can prevent impairing aesthetics.

  According to the present invention, smooth rotation by a rotating hinge can be provided. Further, since the center of the display unit can be rotated while being temporarily separated from the rotary hinge, it is not necessary to increase the distance from the display unit while keeping the display unit in a rectangular shape. In addition, it is possible to prevent the portion of the rotation mechanism including the rotation hinge from being visible from the outside during the rotation. In addition, since the rotating hinge can be made small, the center of the display unit can be made substantially the same position even when the display unit is rotated 90 degrees in either the left or right direction.

  Hereinafter, embodiments for carrying out the present invention will be described with reference to the drawings. In addition, this invention is not limited to the form demonstrated below, It is possible to implement various modifications.

(Embodiment 1)
Fig.1 (a) is a perspective view at the time of seeing the rotation hinge which concerns on one Embodiment of this invention from one direction. Moreover, FIG.1 (b) is a perspective view at the time of seeing the rotation hinge from which a perspective view is shown by Fig.1 (a) from another one direction. FIG. 2 is an assembly configuration diagram of the rotary hinge whose perspective view is shown in FIGS. 1 (a) and 1 (b).

  In the present invention, when the rotary hinge is viewed as illustrated in FIG. 1A, it is referred to as “viewed from an obliquely forward direction”, and when the rotary hinge is viewed as illustrated in FIG. 1B. Is referred to as “looking from a diagonally backward direction”. The front and rear of the rotary hinge according to an embodiment of the present invention are defined thereby. In the present invention, the upward direction in FIGS. 1A and 1B, in other words, the direction going to the depth in FIG. 2 is referred to as the “upward direction”, and FIGS. The downward direction in (b), in other words, the direction toward the front of FIG. 2 is referred to as “downward direction”. Horizontal, vertical, and vertical are defined as a direction perpendicular to and parallel to the upward and downward directions.

  A rotary hinge according to an embodiment of the present invention includes a plate 1, and a passage 2 is formed in the plate 1. The passage 2 is configured as a shape in which two slits intersect. The passage 2 has a shape similar to an X shape as a whole. However, in FIG. 1 and the like, each slit is not a straight line like each side of the X character, but has an S shape, for example. Moreover, although the plate 1 is illustrated as a symmetrical shape, it is not necessarily limited to this.

  In addition, each slit constituting the passage 2 has a first section between the upper end 3 and the first bent portion 4, and a second section between the first bent portion 4 and the second bent portion 5. And the third section between the second bent portion 5 and the lower end 6. The place where the two slits intersect is located in the third section. A movable pin 9 described later passes through each slit of the passage 2 and can move in the slit. As will be described later, as the display unit of the information device rotates, the connecting part 7 rotates and the movable pins 9 fixed to the connecting part 7 move through the respective slits constituting the passage 2. The movable pin 9 is an example in which a protrusion that can move in each slit is provided on the connecting portion 7.

  Here, the “slit” means an elongated hole. In one embodiment of the present invention, as will be described later, a movable pin 9 having a flange is fixed to the connecting portion 7 via a slit from the rear of the plate 1 so that the connecting portion 7 is separated from the plate 1. This is to prevent it from occurring. The means for preventing the connecting portion 7 from separating from the plate 1 is not limited to this. In that case, the channel | path 2 does not need to be formed with a slit, and may be formed as a groove | channel which has a bottom face. In addition, since a slit thru | or a groove | channel is elongate shape, it will have both ends. As shown in FIG. 1 and the like, an upper end of one of both ends is referred to as an “upper end”, and the other end is referred to as a “lower end”.

  The shape of each slit constituting the passage 2 will be described. In each slit, the first bent portion 4 is located below the upper end 3 and on the side where the two slits intersect. In FIGS. 1 and 2, the first section has a shape along a downwardly convex curve from the upper end 3 toward the first bent portion 4. The second bent portion 5 is located above the first bent portion 4 and on the side where the two slits intersect. For example, the second section can be formed in a shape along an arc centered at one point in the first section of the other slit. Or you may form in a substantially linear shape. Further, the lower end 6 is located below the second bent portion 5 and on the opposite side of the portion where the two slits intersect. In FIG. 1 and FIG. 2, the third section is formed along a curved line that protrudes upward from the second bent portion 5 toward the lower end 6. Good.

  When the inclination at an arbitrary position in the slit is defined as the inclination of the center line of the slit at that position, in the embodiment of the present invention, the inclination of the first section before and after the first bent portion 4 and the first The sign of the slope of the second section is different, and the signs of the slope of the second section and the slope of the third section before and after the second bent portion 5 are also different. Accordingly, when paying attention to the height of the center line of the slit, the height is maximum at the upper end 3, is minimum at the first bent portion 4, is maximum at the second bent portion 5, and is minimum at the lower end 6. It becomes.

  As described above, each of the two movable pins 9 moves in each slit. Next, the positional relationship between the two movable pins 9 and the movement in the slit will be described. In the following, one of the two slits is referred to as “one slit” and the other is referred to as “the other slit”. The movable pin 9 that moves in one slit is called “one movable pin 9”, and the movable pin 9 that moves in the other slit is called “the other movable pin 9”. One slit and the other slit may be referred to as a first slit and a second slit. One movable pin 9 and the other movable pin 9 may be referred to as a first movable pin 9 and a second movable pin 9 in some cases. Moreover, one side and the other can correspond not only to 1st and 2nd, respectively, but can also be made to correspond to 2nd and 1st, respectively.

  The two movable pins 9 are fixed to the connecting portion 7 and the distance between the two movable pins 9 is kept constant. And when one movable pin 9 is located in the 1st bending location 4 of one slit, the other movable pin 9 can also be located in the 1st bending location 4 of the other slit. When one movable pin 9 moves from the first bent portion 4 toward the second bent portion 5 in the second section of the one slit, the other movable pin 9 moves to the first slit of the other slit. The section is moved from the first bent portion 4 toward the upper end 3. When one movable pin 9 moves from the second bent portion 5 toward the lower end 6 through the third section of the one slit, the movable pin 9 moves to a location where the two slits intersect (crossing location). In the meantime, the other movable pin 9 is located in the first section of the other slit. For example, the other movable pin 9 moves toward the upper end 3 of the other slit or stops at the upper end 3. When one movable pin 9 passes through the intersection of one slit, the other movable pin 9 moves in the first section of the other slit toward the first bent portion 4, and finally the other slit. The first bent portion 4 is reached.

  In one embodiment of the present invention, the first bent portion 4 is arranged so that the lines connecting the first bent portions 4 of the two slits are horizontal. In addition, when a perpendicular is drawn from the first bent portion 4 of one slit, the shape of the slit is determined so that the perpendicular intersects the third section of the other slit. In this case, the length of the perpendicular is preferably equal to the distance between the two movable pins 9. Two movable pins 9 are positioned at the first bent portion 4, and one movable pin 9 is positioned at the first bent portion 4 and the other movable pin 9 is in the third section of the other slit. This is because the line segment connecting the two movable pins 9 is rotated 90 degrees when compared with the positioned state. Moreover, although the shape of two slits may be bilaterally symmetric, it is not limited to being bilaterally symmetric.

  According to the shape of the slit and the arrangement and movement of the movable pin 9, when each of the two movable pins 9 is located at the first bent portion 4 of each slit, the two movable pins 9 are connected. The line is horizontal. Then, when one movable pin 9 moves in the second section of one slit from the first bent portion 4 toward the second bent portion 5, the center point of the two movable pins 9 moves upward. The connecting portion 7 rotates. Further, when one movable pin 9 moves from the second bent portion 5 of one slit to the portion where the two slits intersect, the connecting portion 7 further continues to rotate. Thereafter, when the other movable pin 9 moves from the direction of the upper end 3 to the first bent portion 4 through the first section of the other slit, the connecting portion 7 continues to rotate. When the other movable pin 9 finally reaches the first bent portion 4 of the other slit, the line connecting the two movable pins 9 becomes vertical. As a result, the line connecting the two movable pins 9 transitions between a horizontal state and a vertical state, and the connecting portion 7 is rotated by 90 degrees.

  The connecting portion 7 is disposed on the front side of the plate 1 via the sleeve 8. As will be described in the second embodiment, when screws or the like are inserted into the connection holes 25 and 26 of the connection portion 7 and connected to the display unit housing, the screws or the like do not contact the plate 1. It is to do. Moreover, it is for making the connection part 7 rotate and move the front side rather than a hinge attachment housing | casing, and make thickness of a display part small.

  The movable pin 9 penetrates the slit and the sleeve 8 from the rear side of the plate 1 and is fixed to the connecting portion 7. A flange is formed at the rear end of the movable pin 9 to prevent the connecting portion 7 and the plate 1 from separating.

  Further, as a feature of the shape of the plate 1, in addition to the two slits being formed, a connecting hole such as a screw hole for attaching each member is formed. Further, as described in the second embodiment, a hole 27 for inserting a screw or the like from the rear of the plate 1 is provided in the connection hole 25 for attaching the connection part 7 to the display unit housing. In order to insert a screw or the like into the connecting hole 26 of the connecting portion 7 from the rear side of the plate 1, a location where two slits intersect when each of the two movable pins 9 is positioned at the first bent portion 4. Is located behind the connecting hole 26.

  Moreover, it is preferable that the recessed part 30 is formed in the part of the upper side located above the cross location of two slits in the plate 1 toward the upper end of two slits. This is because the concave portion 30 is used to route a cable for transmitting and receiving signals to and from the display unit of the display unit casing and connect it to the display unit casing.

  When one movable pin 9 moves from the second bent portion 5 toward the lower end 6 through the third section of one slit, the one movable pin 9 has two slits in the middle. Reach the intersection. At this time, if one movable pin 9 moves to the other slit, the connecting portion 7 may not rotate 90 degrees. Therefore, it is preferable that the rotary hinge is provided with means for preventing one movable pin 9 from entering the slit where the other movable pin 9 is located when the movable pin 9 reaches a position where the slit intersects in the middle.

  As an example for realizing this means, the cross-sectional shape when the movable pin 9 is cut by the surface of the plate 1 or a plane parallel to the plate 1 is not a rotationally symmetric circular shape, but a length in one direction such as an ellipse or a rectangle. The length in the direction perpendicular to the width is made larger, and the length in one direction is made larger than the width of the slit. Thereby, even if one movable pin 9 moves to the place where the slits intersect, it is possible to prevent the other movable pin 9 from entering the other slit that moves.

  As another realization means, as shown in FIG. 1A and FIG. 2, guide pins 10 may be fixed to the connecting portion 7 and guides 11 may be provided on the left and right of the passage 2 of the plate 1. The guide 11 has a planar shape thinner than the thickness of the sleeve 8 so as not to contact the connecting portion 7. Further, the guide pin 10 forms a protrusion on the plate 1 side of the connecting portion 7, and the protrusion does not contact the plate 1. The position of this protrusion is, for example, on the vertical bisector of the two movable pins 9 and is on the lower side of the movable pin 9 when the line connecting the two movable pins 9 is horizontal. Further, as a condition for satisfying the shape of the guide 11, one movable pin 9 moves from the second bent portion 5 toward the lower end 6 through the third section of one slit and reaches the portion where the slits intersect. Then, the guide 11 is positioned below the guide pin 10, and the guide pin 10 and the guide 11 approach, contact, or contact each other, thereby preventing the guide 11 from moving further downward.

  For example, in FIG. 1A and FIG. 2, the guide 11 is substantially Z-shaped, and one movable pin 9 extends from the second bent portion 5 to the lower end of the third section of one slit. When the guide 11 moves to 6 and reaches the point where the slits intersect, the guide 11 further moves downward by approaching, contacting or abutting a portion corresponding to the horizontal line on the Z-shape of the guide 11 below the guide pin 10. Stop moving to.

  In addition, in order to prevent the guide 11 from moving further downward, it is not essential that the shape of the guide 11 is substantially Z-shaped, and when one movable pin 9 reaches a place where the slits intersect. The guide 11 only needs to be positioned below the guide pin 10. The guide pin 10 only needs to be prevented from moving toward the lower end of the other slit by approaching, contacting, or contacting the guide 11.

  Further, the guide 11 is formed in a shape having a convex portion such as a substantially Z shape as shown in FIGS. 1A and 2, so that the connecting portion 7 rotates and the two movable pins 9 are moved. From the state where the connecting line is changed from horizontal to vertical, the guide pin 10 wraps around the convex portion after one movable pin 9 that can prevent the connecting portion 7 from rotating further passes through the portion where the slit intersects. Moving. And it comes to be located in the opposite side of the guide 11 with respect to a crossing location. From this state, when the connecting portion tries to rotate more than 90 degrees around one movable pin 9, the guide pin 10 approaches, contacts, or abuts a portion of the Z-shaped non-horizontal line of the guide 11. As a result, the connecting portion is prevented from rotating more than 90 degrees around one movable pin 9.

  Further, as shown in FIGS. 1A and 2, one movable pin 9 moves from the second bent portion 5 toward the lower end 6 through the third section of one slit, and the slit After reaching the crossing point, the guide pin 10 is moved into the concave portion located on the side of the guide 11 opposite to the point where the slits cross, and the line connecting the two movable pins 9 becomes vertical. In some cases, the guide pin 10 is positioned in the recess. Thereby, even if the connection part 7 tries to rotate further, the guide 11 prevents the movement of the guide pin 10 more effectively, and further suppresses and prevents the connection part 7 from rotating.

  The guide 11 may be formed as a component different from the plate 1 as shown in FIGS. In this case, it can be fixed to the plate 1 by the guide fixing pin 12. Alternatively, the plate 1 and the guide 11 can be fixed by adhesion or welding. Alternatively, the guide 11 can be formed integrally with the plate 1. For example, when the plate 1 is formed by pressing, the guide 31 can be formed as a convex portion by the pressing as shown in FIG. Of course, after the plate 1 is formed first, the guide 31 can be formed by press working.

  In order to make the line connecting the two movable pins 9 horizontal and vertical, the connecting part 7 may be urged from above. In this case, as shown in FIG. 1 (b), a lever 14 is provided behind the plate 1 so that a force is applied from above both or one of the movable pins 9. In this case, as shown in FIG. 1B, the lever 14 has a substantially U shape with the inside facing downward, and the bottom of the U shape contacts both or one of the movable pins 9. The lever 14 is movable upward and downward using the lever mounting pin 13 so as not to be separated from the plate 1.

  As shown in FIG. 1A, FIG. 1B, and FIG. 2, one end of the torsion spring 17 is connected to the end of the U-shaped open side by a fixing pin 15, and the other end of the torsion spring 17 is connected to the other end. It is fixed to the plate 1 by a fixing pin 16. When the torsion spring 17 is to be deformed so that the distance between both ends thereof is reduced, a force is applied to the movable pin 9 from above by the lever 14. As a result, when both or one of the movable pins 9 is at the first bent portion 4, the force applied to the lever 14 by the torsion spring 17 when moving the movable pin 9 from that state is: It is necessary to apply a force in the opposite direction. That is, the case where the line connecting the two movable pins 9 is horizontal and the case where the line is vertical are in a mechanically stable state.

  The biasing is not limited to using the torsion spring 17. A downward force can be applied to the lever 14 by an elastic body such as rubber or a spring. For example, as shown in FIG. 4A, the height of the lever 144 is made smaller than that shown in FIGS. 1A, 1B, and 2, and the end 41 of the U-shaped opening is formed. And the convex part 42 provided in the plate 1 may be connected by the coil spring 43, and you may make it attract. In this case, the elastic body such as the coil spring 43 becomes longer than the natural length after the arrangement. As a result, the coil spring 43 and the like pulls the end point 41 of the U-shaped open portion so as to return to the natural length, so that a downward force is applied to the lever 144.

  Alternatively, the biasing can be performed in a state where the length of the elastic body is smaller than the natural length. For example, as shown in FIG. 4B, a slit or the like is provided inside the U-shaped vertically extending portion of the lever 145, and a convex portion 44 directed to the plate 1 and a lower end point 45 such as the slit are formed. A coil spring 46 may be disposed between them. In this case, the length of the coil spring 46 is shorter than the natural length. As a result, the coil spring 43 or the like presses a lower end point 45 such as a slit to return to the natural length, so that a downward force is applied to the lever 145.

  In either case of FIG. 1 or FIG. 4, the moving distance that the lever moves up and down is the vertical height when the movable pin 9 moves in the first section of the slit of the passage 2, and the moving distance is reduced. Can do.

  In addition, when the two movable pins 9 are respectively positioned at the first bent portion 4, it is preferable that the upper side of the outer side of the lever is positioned below the recess 30 and positioned in the plate 1. This is because, as will be described later, it becomes possible to connect the cable to the concave portion 30 and connect it to the display unit housing, as will be described later.

  Note that the shape of the plate can be arbitrary, except that a concave portion is provided on the upper side of the plate 1. For example, there may be a horizontal portion other than the concave portion as shown in FIG. 4A, or an upward convex shape as shown in FIG. 4B.

  FIG. 5 shows a state in which the connecting portion 7 rotates 90 degrees clockwise when the rotary hinge according to the embodiment of the present invention is viewed from the front. In FIG. 5, the rotation angle when the line connecting the two movable pins is horizontal is 0 degree. And the three stages in the middle up to 90 degrees are set to 22.5 degrees, 45 degrees, and 67.5 degrees. The first row from the top of FIG. 5 shows the case where the rotary hinge is viewed from the front, and the next second row shows the case where the rotary hinge is viewed from the rear. In addition, the values of 22.5 degrees, 45 degrees, and 67.5 degrees, which are angles in the middle of rotation, are examples, and may vary depending on the shape of the slit of the passage 2.

  When the rotation angle is 0 degree, the two movable pins are located at the first bent portions of the respective slits. And since the downward force is applied by the lever, it is mechanically stable.

  When the rotation angle is 22.5 degrees, one movable pin is located at the second bent portion of one slit, and the other movable pin is located in the middle of the first section of the other slit. ing. Compared to the case of 0 degree, the connecting portion is located above.

  When the rotation angle is 45 degrees, one movable pin is positioned at the intersection of the two slits, and the other movable pin is positioned at the upper end of the other slit. At this time, the movable pin is in contact with the upper part of the left guide. This prevents one movable pin from entering the other slit. As shown in the third row of FIG. 5, if there is no guide, one movable pin can move to both of the slits, and the connection part may not be able to achieve 90-degree rotation. .

  Further, when the rotation angle becomes 67.5 degrees, one movable pin passes through a portion where the slits intersect, and the other movable pin is positioned in the middle of the first section of the other slit.

  When the rotation angle is 90 degrees, the other movable pin is positioned at the first bent portion of the other slit. At this time, since a downward force is applied by the lever, it is mechanically stable. In FIG. 5, one movable pin is located at the lower end of one slit. Moreover, a guide pin will be located in the recessed part of the left guide. A guide exists between the line segment connecting the movable pins and the guide pin. This prevents the guide pin from moving obliquely upward to the right. Accordingly, rotation beyond 90 degrees is prevented. As shown in the third row of FIG. 5, if there is no guide, it will rotate more than 90 degrees.

  In the above description, the process in which the connecting portion 7 rotates 90 degrees clockwise has been described, but the process in which the connection part 7 rotates 90 degrees counterclockwise can be described in the same manner. In the above description, “one slit” and “the other slit” are respectively referred to as “first slit” and “second slit”, and “one movable pin” and “the other movable pin” are referred to as “first slit”. Assuming that “movable pin” and “second movable pin” are used, the process in which the connecting portion 7 rotates 90 degrees counterclockwise can be described as follows.

  That is, when the connecting portion 7 is rotated 22.5 degrees counterclockwise, the second movable pin is positioned at the second bent portion of the second slit, and the first movable pin is Located in the middle of the first section of the slit.

  When the connecting portion 7 is rotated 45 degrees counterclockwise, the second movable pin is positioned at the intersection of the two slits, and the first movable pin is positioned at the upper end of the first slit. ing. At this time, the movable pin is in contact with the upper part of the right guide.

  Further, when the connecting portion 7 is rotated 67.5 degrees counterclockwise, the second movable pin passes through the portion where the second slit intersects, and the first movable pin is the first section of the first slit. Will be located in the middle.

  Thereafter, the first movable pin moves to the first bent portion of the first slit, the second movable pin moves in the third section of the second slit, and the connecting portion 7 rotates counterclockwise. Rotate 90 degrees.

  As described above, in the rotary hinge according to the embodiment of the present invention, the movable pin fixed to the connecting portion moves through the passage formed by intersecting two substantially S-shaped slits. In particular, since the movable pin reciprocates in the first section of the slit while the connecting portion rotates from 0 degree to 90 degrees, the entire width of the passage can be reduced, and the rotating hinge can be downsized. Further, since the overall shape of the slit of the passage is an S-shape that is bent relatively gently, the connecting portion can be smoothly rotated.

  In addition, the position of the movable pin when the connecting portion is rotated 90 degrees to the left and the position of the movable pin when the connecting portion is rotated 90 degrees to the right are the second bisection of the first bent portions. It can be point-symmetric with respect to a point on the dividing line. Therefore, when the display unit housing is fixed to the connecting unit 7, the center of the display unit housing can be positioned on the substantially center line of the operation unit even if the display unit housing is rotated 90 degrees to the left and right. Thereby, the line symmetry of information equipment can be maintained, and an operator can be given a aesthetic feeling.

  Moreover, since the whole rotation hinge can be made line symmetrical, it can prevent that the gravity center of information equipment deviates.

  In addition, when one movable pin moves in the second section, the connecting portion moves upward while rotating, so that the lower angle of the display unit housing fixed to the rotating portion has a rotation angle of 0. Can be prevented from entering the portion below the lower side of the display unit housing.

  In addition, a recess can be provided on the upper side of the plate of the rotary hinge, and a cable for transmitting and receiving signals to and from the display housing can be routed through the recess and connected to the display housing.

(Embodiment 2)
FIG. 6 is an assembly configuration diagram of the display unit when the rotary hinge according to the embodiment of the present invention is applied to the configuration of the display unit of the mobile phone which is an example of the information device.

  A rotary hinge according to an embodiment of the present invention is attached to the rear of the hinge mounting housing 64 using screws 65. That is, screw holes and the like provided in the plate 1 and the hinge mounting housing 64 are made to coincide with each other, and a screw 65 or the like is inserted. As a result, the rotary hinge according to the embodiment of the present invention is fixed to the hinge mounting housing 64. In this case, the thickness of the sleeve 8 and the thickness of the hinge mounting housing 64 are selected so that the connecting portion 7 can rotate and move in front of the hinge mounting housing 64. That is, the thickness of the sleeve 8 is set to be equal to or greater than the thickness of the hinge mounting housing 64.

  Next, the display part housing | casing 70 provided with the display part 71 from the front of the hinge attachment housing | casing 64 is fixed to the connection part 7 using the attachment part 72 attached to the back. That is, a fixing screw 81 or the like is inserted from the rear of the plate 1 through the hole 27 and a portion where the two slits intersect, and the attachment portion 72 is fixed to the connecting portion 7. In addition, the display unit housing 70 has a recessed portion where the mounting unit 72 is mounted, and cancels the increase in the thickness of the entire display unit due to the connection unit 7 being separated from the plate 1. You may be able to.

  A recess 82 is provided in the upper side portion between the two side sides of the hinge mounting housing 64. In other words, the recessed portion 82 is provided in the hinge mounting housing 64, and as a result, the two sides of the hinge mounting housing 64 protrude. One reason for this is to enable the attachment portion 72 to be fixed to the connecting portion 7 using the fixing screw 81. Another reason is that the guide 11 is arranged in the inner portion 83 of the recess 82 to cancel the increase in thickness due to the guide 11. Another reason for this is that the recess 82 allows the cable to be routed through the recess 30 of the plate 1.

  It is not necessary to provide the guide 11 on the plate 1. The movable range of the guide pin 10 can be limited by the inner portion 83 of the concave portion 82 of the hinge mounting housing, and by this limitation, the movable range of the movable pin 9 attached to the connecting portion 7 is limited. Can do. Therefore, it is possible to prevent the movable pin 9 from entering another slit or the connecting portion 7 from rotating 90 degrees or more.

  In an actual product, in order to prevent the rotary hinge from being seen from the rear of the display unit, or in order to prevent the rotary hinge from being contacted, the hinge mounting housing 64 is provided with the rotary hinge and the display unit housing. After the cover 70 is attached, the cover is attached to the hinge attachment housing 64. The height of this cover is preferably as small as possible. This is because it is preferable that the cover is not visible from the front of the display unit casing 70 even if the display unit casing 70 is rotated 90 degrees clockwise or counterclockwise. Therefore, it is preferable that the upper side of the cover is a straight line connecting the upper sides of the protruding side edges for forming the recess 82 of the hinge mounting housing 64.

  FIG. 7 shows a state of rotation of the display unit housing 70 in one embodiment of the present invention in which the rotary hinge according to one embodiment of the present invention is used for the configuration of the display unit of the mobile phone. Moreover, the side view of the mobile phone which concerns on one Embodiment of this invention is shown by the left side of FIG. In the cellular phone, an operation unit housing 701 on which a numeric keypad, a power button, and the like are arranged, and a hinge mounting housing 702 are connected via a folding hinge 703. And the hinge attachment housing | casing 702 and the display part housing | casing 704 are connected via the rotation hinge which concerns on one Embodiment of this invention. In addition, the rotation hinge which concerns on one Embodiment of this invention is arrange | positioned in the location pointed with the code | symbol 705, and the increase in the thickness of the display part by the rotation hinge which concerns on one Embodiment of this invention is negated.

  On the right side of the side surface of the mobile phone shown in FIG. 7, the position of the upper part of the folding hinge 703 is indicated by a one-dot chain line with the reference position as a reference position. Are illustrated in five stages from 0 to 90 degrees, 22.5 degrees, 45 degrees, and 67.5 degrees. For ease of viewing, the display housing is illustrated as being transparent, and the hinge mounting housing 64 is illustrated as being opaque. Note that the rotation angle values of 22.5 degrees, 45 degrees, and 67.5 degrees are merely examples, as shown in FIG.

  At the rotation angle of 0 degree, the connecting portion is located at the center inside the recess 82. When the rotation angle is rotated from 0 degree to 22.5 degrees, one movable pin moves in the second section of one passage from the first bent part to the second bent part, and the other The movable pin moves in the first section of the other slit of the passage from the first bent portion toward the upper end. As a result, the connecting portion rotates and moves obliquely upward. Therefore, the lower right corner of the display unit housing 704 can be prevented from entering below the alternate long and short dash line. In other words, the rotated display unit housing 704 can be positioned above the lower side of the display unit housing 704 when the rotation angle is 0 degree.

  While the rotation angle is increased from 22.5 degrees to 45 degrees, the other movable pin can move further obliquely upward in the first section of the other passage. These corners do not enter below the dashed line.

  As described in the first embodiment, since the rotary hinge according to one embodiment of the present invention can be downsized, the rotation angle is changed from 22.5 degrees to 45 degrees as shown in FIG. During the change, the inside of the recess 82 on the upper side of the hinge mounting housing can be always covered with the display housing 704.

  When the rotation angle is increased from 45 degrees to 67.5 degrees, the display unit housing 704 rotates around the other movable pin. Accordingly, the lower right corner of the display unit housing 704 moves above the one-dot chain line.

  When the rotation angle is rotated from 67.5 degrees to 90 degrees, the other movable pin moves downward in the first section of the other passage, and one movable pin also moves in the third section of the one passage. Move down. Accordingly, the display housing 704 is finally rotated by 90 degrees.

  Even if the display unit housing 704 is finally rotated by 90 degrees, the rotary hinge according to the embodiment of the present invention can be downsized, so that the upper part of the hinge mounting housing is displayed as shown in the figure. Since it is covered with a partial housing, it is possible to prevent a loss of aesthetics.

  A case where the display housing 704 is rotated 90 degrees counterclockwise is shown in the lower half of FIG. Since this is the same as the case where the line is rotated 90 degrees clockwise, the description is omitted. The position of the movable pin when the connecting portion is rotated 90 degrees clockwise, and the position of the movable pin when the connection portion is rotated 90 degrees conversely, with respect to a point on the vertical bisector of the first bent portion As shown in FIG. 7, when the display unit housing 704 is rotated 90 degrees clockwise and reversely 90 degrees, as shown in FIG. It is possible to make the positions of the upper, lower, left and right of the same. In other words, when the rotation angle is 0 degree and when it is rotated 90 degrees clockwise or counterclockwise, the shape of the display unit case can be made symmetrical with respect to substantially the same vertical line. it can. Thereby, it can prevent further that aesthetics are spoiled.

  The “substantially the same vertical line” refers to a vertical line that is a symmetric line when the rotation angle is 0 degree and a vertical line that is a symmetric line when rotated 90 degrees clockwise or counterclockwise. This includes the case where two vertical lines are the same. Further, even if they are not the same, the distance between the two vertical lines is a distance of 5% or less, preferably a distance of 2% or less with respect to the width when the display unit housing is rotated 90 degrees. . This is because if it is 5% or less, preferably 2% or less, it will appear to be almost symmetrical in human vision before and after rotation.

(Embodiment 3)
As described above, the rotary hinge according to the embodiment of the present invention has the concave portion 30 formed in the plate 1 as shown in FIG. A cable for transmitting and receiving signals to and from the display unit can be connected.

  FIG. 8 is a perspective view of a cellular phone that is an example of an information device according to an embodiment of the present invention when the cable is connected to the display housing from the rear. A through hole 801 is provided in the rear of the display unit housing 70, and a cable 802 extending from the folding hinge 703 is routed from the side of the plate 1 of the rotary hinge according to an embodiment of the present invention to pass through. It is inserted into the wire hole 801.

  FIG. 9 shows the shape and position of the through hole 801 provided in the display unit housing 70. The through hole 801 is provided in the upper part of the attachment portion 72. In particular, the display unit housing 704 is provided in a flat shape at the upper and lower center positions when the rotation angle of the display unit housing 704 is 0 degree. In FIG. 9, the shape of the through hole 801 is a shape obtained by cutting the vicinity of the end point of the arc from the shape obtained by cutting the circle with an arc whose circumferential angle is smaller than 180 degrees, but is not limited thereto. However, as will be described below, the upper side of the through hole 801 is preferably an arc. The center of the circular arc is preferably the rotation center of the display unit housing 70.

  Further, FIG. 9 shows that in the case where the through hole 801 is provided in the display unit housing 70, the position of the through hole 801 is set to 22.5 degrees from the rotation angle of the display unit housing 70 to 0 degrees to 90 degrees, The cases of 45 degrees and 67.5 degrees are also shown.

  If the upper side of the through-hole 801 is an arc, the cable can be passed through the locations indicated by reference numerals 901, 902, 903, and 904 in FIG. When the rotation angle of the display unit housing 70 is 90 degrees, it seems that the entire through hole 801 is covered with the plate of the rotary hinge. However, as shown in FIG. 6, the distance between the plate 1 of the rotary hinge and the display housing 70 is a distance of the thickness of the hinge mounting housing 64, so that the diameter of the cable is set to the hinge mounting housing 64. By making the thickness equal to or less than the thickness of the cable, the cable can be routed through a portion indicated by reference numeral 905.

  Of course, by making the width of the through hole 801 larger than that shown in FIG. 9, even if the rotation angle of the display unit housing 704 is 90 degrees, the entire through hole 801 is covered with the plate of the rotary hinge. It can be prevented from being broken. However, in such a case, when the rotation angle of the display unit housing 704 is 45 degrees, 67.5 degrees, or the like, a part of the through hole 801 may be seen from the rear of the display unit housing 70. is there.

Therefore, it is preferable that the shape and position of the through-hole 801 are always covered with a cover attached to the hinge attachment housing 64. In other words, even when the display unit housing 70 is rotated 90 degrees clockwise from 0 ° and / or counterclockwise, the entire through hole 801 protrudes to form the recess 82 of the display unit mounting housing 64. It is preferable to be located below a straight line connecting the upper sides of the side edges.
As one solution for this, the upper side of the through hole 801 is formed in an arc shape.

  Since the rotating hinge according to the embodiment of the present invention can be miniaturized, a cable can be arranged on the side thereof. Moreover, since a recessed part can be provided in a plate, it is possible to route a cable there. Further, since the rotation is possible as the center of the display unit casing, if a through hole is provided in the center portion, it is possible to prevent an excessive force from being applied to the cable even if the display unit casing is rotated.

(Embodiment 4)
As Embodiment 4 of the present invention, a rotating hinge using a variation of a lever used to apply force from above the movable pin and an information device using the same will be described.

  FIG. 10A is a perspective view of the rotary hinge according to the present embodiment as viewed from an obliquely forward direction, and FIG. 10B is a perspective view of the rotary hinge according to the present embodiment as viewed from an obliquely rearward direction. is there. In FIGS. 1A and 1B, the lever 14 used to apply force from above the movable pin 9 has an inverted U shape, but in FIGS. 10A and 10B, The lever 146 is U-shaped.

  That is, the lever 146 has a first portion and a second portion that extend vertically in parallel with the side of the plate. Both or one of the first part and the second part of the lever 146 is in contact with both or one of the movable pins 9. An elastic body such as a torsion spring that connects both the lever 146 and the plate 1 forces the movable pin 9 that is in contact with one or both of the first portion and the second portion toward the first bent portion. Is added. In FIG. 11, both the first portion and the second portion of the lever 146 are in contact with both the movable pins 9, but when the rotation angle of the connecting portion becomes a predetermined angle or more, the first portion of the lever 146 One of the second part and the second part is no longer in contact with one of the movable pins 9, and the other of the first and second parts of the lever 146 is in contact with the other of the movable pins 9, Continue to apply force toward the bend of 1.

  The lever 146 has a third portion that connects the first portion and the second portion. In FIG. 11, the third portion is located below the plate 1 and connects the lower end of the first portion and the lower end of the second portion, but is limited to this. There is no. One of the features of this embodiment is that the third part does not connect the upper part of the first part and the upper part of the second part, and is always located under the recess 30 at the upper part of the plate 1. It is that.

  Further, it is preferable that the upper side of the lever 146 is not positioned above the upper side of the plate 1 even if the connecting portion rotates. In other words, the upper side of the lever 146 can be positioned below the upper side of the plate 1 while one of the movable pins moves toward the upper end as the connecting portion rotates. In particular, even if one of the movable pins is farthest from the crossing position of the slit, the upper side of the lever 146 is positioned below the upper side of the plate 1. It should be noted that “below the upper side of the plate 1” may include a case where the height of the upper side of the plate 1 coincides.

  In this way, the third portion is always located below the recess 30 at the top of the plate 1, and preferably, even if one of the movable pins is furthest away from the crossing position of the slit, the upper side of the lever 146 is When the rotary hinge according to this embodiment is used for an information device or the like by being positioned below the upper side of the plate 1, as will be described below, a cable and a lever connected to the display unit housing of the information device Can be prevented from coming into contact with each other, and damage to the cable can be prevented. In addition, the cable routing can be easily changed.

  FIG. 11 is a perspective view of an information device using the rotary hinge according to the present embodiment when viewed obliquely from behind the display unit. Similar to FIG. 8, a through hole 801 is provided in the rear of the display unit housing 70, and a cable 802 extending from the folding hinge 703 is located on the side of the rotary hinge plate 1 according to the embodiment of the present invention. The upper side is drawn from the side and inserted into the through hole 801. However, the difference between FIG. 11 and FIG. 8 is the shape of the lever.

  Due to the difference in the shape of the lever, even if the connecting portion rotates and the lever 146 moves upward as the display unit housing 70 rotates, the upper side of the lever 146 is above the upper side of the plate 1. Not located. Therefore, the lever 146 does not come into contact with the cable routed around the upper side of the plate 1.

  The lever 146 may be configured by removing the third portion from the lever 146 and separating the first portion and the second portion. However, in this case, in a state where only one of the first part and the second part is in contact with the movable pin, the force that pushes the movable pin toward the first bent portion compared to the case where the third part exists. As the becomes smaller, the mechanical stability decreases. For this reason, it is necessary to connect the 1st part and the 2nd part, and the plate 1 using the torsion spring etc. which generate | occur | produce a big force. In this case, the size of the torsion spring or the like may increase.

  Also in this embodiment, as shown in FIG. 4, it is also possible to use a coil spring instead of the torsion spring.

  Further, as shown in FIG. 1 and the like, even if the third portion of the lever 14 connects the upper portion of the first portion and the upper portion of the second portion, the shape of the concave portion 30 of the plate 1 is devised. And the effect similar to this embodiment can be acquired by reducing the grade of a hollow or making the width | variety of the 3rd part of the lever 14 small. However, in the former case, the height of the rotary hinge may increase. In the latter case, the strength of the third portion may be insufficient.

  As described above, according to the present embodiment, the lever can be prevented from coming into contact with the cable, and damage to the cable can be prevented. Moreover, it is possible to prevent an increase in the height of the rotary hinge and a decrease in the strength of the lever.

(Examples and Comparative Examples)
FIG. 12A shows a case where a width of 50 mm and a height of 93.5 mm are selected as a display unit casing for a mobile phone, and a rotating hinge according to an embodiment of the present invention is attached to the display unit casing. The example which projected the shape of the channel | path 2 of this to the display part housing | casing is shown. As shown in FIG. 12A, the maximum width of the passage 2 could be about 23 mm. Therefore, it was shown that it is possible to make it less than half the width of the display unit housing.

  On the other hand, FIG. 12B shows, as a comparative example, another passage of a rotating hinge that rotates a display unit housing for a mobile phone 90 degrees clockwise and counterclockwise, and the shape of the passage is displayed on the display unit. An example of projection onto a housing is shown. As shown in FIG. 12B, the maximum width of the passage was about 38 mm. Therefore, the size is larger than that of the rotary hinge according to the embodiment of the present invention.

  In addition, the outline of a structure of the rotation hinge of FIG.12 (b) is as follows. That is, the passage is provided with a first passage in which a left-side portion 1001 that is convex upward, a right-side portion 1002 that is also convex upward, and a first straight passage, and is provided above and apart from the first passage. It is configured with a certain second passage 1003. And the connection member which connects the 1st pin which can move the 1st passage, and the 2nd pin which can move the 2nd passage is fixed to a display part case. When the rotation angle of the display unit housing is 0 degree, the first pin is located at the connecting portion between the left portion 1001 and the right portion 1002, and the second pin is located at the upper end of the second passage. Located in the part. When the rotation angle of the display unit housing is increased, the first pin moves toward the end portion of the left portion 1001 or the right portion 1002, and the second pin moves the second passage to the lower end portion. Move towards. When the rotation angle of the display unit housing is 90 degrees, the first pin is located at the leftmost end of the left portion 1001 or the rightmost end of the right portion 1002 and the second pin is below the second passage. It will be located at the end part.

  Comparing the shapes of the passages in FIG. 12A and FIG. 12B, in FIG. 12B, when the rotation angle of the display unit casing is close to 90 degrees, the first pin where the first pin is located is displayed. The curvature of the passage is larger than that in FIG. For this reason, when the rotating hinge of FIG. 12A according to an embodiment of the present invention is used, it becomes easier to smoothly rotate the display unit housing than the rotating hinge of FIG.

  As described above, according to the present invention, it is possible to provide a smooth rotation, and it is possible to rotate the display unit while temporarily separating the center of the display unit from the rotary hinge. Thus, there is no need to increase the distance from the display unit while maintaining the same. In addition, it is possible to prevent the portion of the rotation mechanism including the rotation hinge from being visible from the outside during the rotation. In addition, even when the display unit is rotated 90 degrees in either the left or right direction, the effect that the center of the display unit can be made substantially the same position can be obtained. Therefore, it is industrially useful.
