Description

  The present invention relates to an open / close type communication terminal provided with a small hinge device in which a gap between a rotation shaft and a cover member is small and a rotation radius of the rotation shaft is small.

  As a conventional open / close type communication terminal, for example, there is one disclosed in Japanese Patent Laid-Open No. 2001-251406 in which one housing rotates in a direction orthogonal to the open / close direction. The openable portable terminal device of the publication includes an input unit for inputting information, a display unit for displaying an operation state monitor and received data, a control unit for controlling the input unit and the display unit, and a housing. It is configured. Note that the input unit includes a first input unit such as a numeric key and a second input unit such as a function key. The housing is divided into a first housing provided with a second input portion and a second housing provided with a display portion and a second input portion, and is rotatable by a hinge portion. The first casing and the second casing are connected to each other and can be opened and closed with the hinge portion as a rotation axis.

  As a hinge device that realizes such a hinge portion, for example, there is one disclosed in Japanese Patent Application Laid-Open No. 2000-240636. Hereinafter, with reference to FIG. 11, a hinge device disclosed in Japanese Patent Laid-Open No. 2000-240636 will be described. FIG. 11 is a plan view (A) and a side view (B) of the hinge device disclosed in Japanese Patent Laid-Open No. 2000-240636.

  The hinge device shown in FIG. 11 includes an opening / closing shaft 202 that is rotatably supported by the opening / closing shaft support portion 201, a rotating shaft 203 that passes through the opening / closing shaft 202 in an orthogonal state, and an opening / closing shaft opening / closing portion. An angle restricting piece 204 provided so as to abut against the shaft 202, a restricting flange 205 protruding from the rotating shaft 203, and a rotation restricting portion 206 facing the restricting flange 205 attached to the opening / closing shaft supporting portion 201, It is configured with. When the hinge device is applied to the open / close communication terminal described above, the size of the hinge portion serving as the rotation axis is the distance between the tip of the angle regulating piece 204 interlocked with the rotation of the rotation shaft 203 and the axis of the rotation shaft 203. Determined by R.

  Also, as a conventional open / close communication terminal, there is one disclosed in JP-A-6-31216. The mobile phone disclosed in the publication includes a first case composed of a first front case and a first rear cover, and a second case composed of a second front case and a second rear cover.

  However, in the above-described conventional communication terminal, even if a conventional hinge part is mounted on a device such as a mobile phone that is required to be downsized to realize an openable mobile phone or the like, the size of the hinge part is small. For this reason, there is a problem that the size of the apparatus is increased. The size of the hinge portion is determined by the diameter of the opening / closing shaft and the rotation radius of the angle restricting piece provided at the end of the rotating shaft. However, in the configuration in which the angle restricting piece is provided at the end of the rotating shaft, the rotating radius is large. As a result, there is a problem that the size of the hinge portion becomes large.

  Furthermore, since the openable mobile phone and the like have a structure in which bending stress and torsional stress are generated in the flexible printed circuit board in accordance with the opening and closing operation, there is a possibility that the conductor (circuit pattern) of the flexible printed circuit board may be cut. It was.

  FIG. 12 is a plan view of a flexible printed circuit board through which a conventional hinge portion is inserted. As shown in the figure, the flexible printed circuit board 300 is spirally wound in a hinge portion in order to be connected to connectors provided in a first housing and a second housing (not shown), respectively. . The twist angle P (see FIG. 12) of the flexible printed circuit board wound clockwise from the lower side to the upper side does not change even when the casing is folded. Note that the folded case is indicated by a two-dot chain line.

  However, both ends of the flexible printed board do not change positions (left and right directions) fixed to the first casing and the second casing, and therefore when twisted from the open state, the twist angle P is approximately P / 2. To change. That is, the flexible printed circuit board is subjected to bending stress and twisting stress by folding.

  In general, a flexible printed board has flexibility and a structure that is sufficiently strong against bending stress. However, when various stresses are applied in combination, disconnection, breakage, and the like are caused. Therefore, in the conventional open / close type mobile phone, if the open / close operation is repeated, the flexible printed circuit board may be disconnected or broken, and there is room for improvement in this respect.

  Further, in the hinge device (see FIG. 11) described in Japanese Patent Laid-Open No. 2000-240636 described above, when an exterior cover that covers the opening / closing shaft 202 and the rotating shaft 203 is provided, the opening / closing shaft in the opening / closing shaft support portion 201 is provided. Since 202 is configured to rotate, the exterior cover cannot be brought into close contact with the opening / closing shaft support 201 in order to avoid wear with the opening / closing shaft support 201. For this reason, a gap is formed between the exterior cover and the opening / closing shaft 202, but rainwater or the like may enter the gap and cause corrosion of the equipment.

  The present invention has been made in view of the above-described conventional problems, and provides a hinge device having a small gap between a rotating shaft and a cover member, and an open / close type communication terminal including the hinge device.

If the housing 101 is not closed (first and second open states), the first permanent magnet 114 is separated from the first Hall element 110, so that the first Hall element 110 is the first permanent magnet 114. Cannot be detected, the first Hall element 110 does not generate a detection signal.

  In addition, when the housing 101 is in the closed state and the first open state, the second permanent magnet 115 is close to the second Hall element 111, so the second Hall element 111 detects the second permanent magnet 115 and controls the control unit 122. A detection signal is sent to. Further, when the housing 101 is in the second open state, the second permanent magnet 115 is separated from the second Hall element 111, and the second Hall element 111 cannot detect the second permanent magnet 115, and therefore does not generate a detection signal. That is, the control unit 122 opens / closes and rotates the first casing member 101a and the second casing member 101b depending on whether or not the detection signals from the first and second Hall elements 110 and 111 are received.

  The first coil spring 129 biases the first click convex plate 130 toward the first click concave plate 131. When the housing 101 is in the closed state and the first open state, the convex portion 130 a of the first click convex plate 130 is engaged with the concave portion 131 a of the first click concave plate 131. When the housing 101 is changed from the first open state to the closed state, the engagement between the convex portion 130a and the concave portion 131a is released. On the other hand, when the casing 101 is changed from the closed state to the first open state, the convex portion 130a and the concave portion 131a. And engage. That is, as a result, the user can feel a click when engaging or disengaging the convex portion 130a and the concave portion 131a.

  A cam 132, a support plate 127, a second click convex plate 133, a second coil spring 134, and a bracket 135 are attached to the second rotation shaft 126 from the upper side in the middle of FIG. The second rotation shaft 126 is supported by a support plate 127 attached to the notch portion 125 a of the first rotation shaft 125 and a support portion 125 b of the first rotation shaft 125. An E-ring 136 is provided at the tip of the second rotation shaft 126 and is rotatably held by the first rotation shaft 125. The second click convex plate 133 is provided to be movable only in the thrust direction of the second rotation shaft 126. Further, the second coil spring 134 biases the second click convex plate 133 toward the support plate 127.

  The convex portion 133a of the second click convex plate 133 is engaged with the concave portion 127a of the support plate 127 only when the housing 101 is changed from the closed state to the first open state or only in the second open state.

Further, the left hatched portion indicates the large diameter portion 128a of the guide shaft 128, and the arc portion indicates the parallel groove 128c. Here, the position of the cam 132 when the housing 101 is in the closed state is indicated by a position a. Further, the position of the cam 132 when the housing 101 is in the first open state is indicated by a position b.

  At the position a, the left and right end surfaces of the cam 132 are surrounded by the partition portion 125c and the large-diameter portion 128a of the guide shaft 128, so that the cam 132 cannot rotate. At the position b, the partition portion 125c is provided on the right end surface side of the cam 132, so that it cannot be rotated to the opposite side to the S direction. Since there is a parallel groove 128c on the left end face side of the cam 132, it can be rotated 180 degrees in the S direction. In the state rotated 180 degrees in the S direction (second open state), a part of the cam 132 is in the parallel groove 128c. In this state, the plate thickness direction of the cam 132 is surrounded by the parallel groove 128c. An attempt to change the housing 101 to the closed state is suppressed.

  Therefore, in a state between the case 101 and the first open state, the first case member 101a cannot rotate around the second rotation shaft 126. In the first open state, the first casing member 101a can be rotated up to 180 degrees in the S direction, but cannot be rotated in the opposite direction to the S direction. Further, in the second open state and the state between the first open state and the second open state, the first rotation shaft 125 cannot rotate, and thus the casing 101 cannot be opened and closed.

  A flexible substrate 139 and a cable 140 are assembled to the hinge unit 138. A flexible substrate 139 having a corner portion 139a electrically connects the first housing member 101a and the second housing member 101b. One end side of the corner portion 139a is wound around the first rotation shaft bearing 137 to form a first winding portion 139b, and the corner portion 139a is passed through the groove 137a into the first rotation shaft bearing 137. The The other end side of the corner portion 139a passes through the slit 125d and escapes from the first rotation shaft 125, is wound about a half turn around the first rotation shaft 125, and further around the second rotation shaft 126. It is wound to form a second winding part 139c and connected to the first casing member 101a.

  A cable 140 that electrically connects the antenna 103 provided in the first housing member 101 a and the transmission / reception unit 117 provided in the second housing member 101 b is connected to the end of the first rotation shaft bearing 137. It passes through the first rotation shaft bearing 137, extends from the slit 125d and extends toward the first casing member 101a, and is connected to the antenna 103 through the inside of the second winding part 139c.

  After the flexible substrate 139 and the cable 140 are assembled to the hinge unit 138, the exterior front cover 141 and the rear cover 142 are fixed by the fastening screws 143. The front cover 141 and the rear cover 142 are provided with engaging claws 141a and 142a and screw insertion holes 141b and 142b, respectively. The screw insertion holes 141 b and 142 b are provided so as to face the bracket 135 provided on the second rotation shaft 126. Further, the front cover 141 and the rear cover 142 are sandwiched so as to surround the hinge unit 138, and the engaging claws 141a and 142a are engaged. The fastening screw 143 passes through the screw insertion holes 141b and 142b, and the screw hole of the first rotating shaft 125. The hinge part 102 is completed by this structure by screwing to 125e.

  A D-cut portion 128d formed at the tip of the small-diameter portion 128b is supported by a D-shaped hole 101e provided in the hinge mounting portion 101c of the second casing member 101b. The outer periphery is supported by the bearing portion 101f of the hinge mounting portion 101d of the second casing member 101b, and the hinge portion 102 is mounted on the second casing member 101b. The first casing member 101a is attached to the bracket 135.

  In the communication terminal according to the present embodiment configured as described above, the user can use the receiver 106 with his / her ears on the receiver 106 in the first open state, or can be used in a hands-free manner with the hand. . In addition, when reading mail or inputting characters, the operation unit 105 and the first display unit 112 face the user side. At this time, the speaker 107 can be covered with either left or right hand. Therefore, the user can hear the sound output from the speaker 107 clearly.

  Next, with reference to FIGS. 1-10, operation | movement of the communication terminal of this embodiment is demonstrated. FIG. 10 is an explanatory diagram for explaining functions of each mode of the communication terminal according to the embodiment of the present invention. As shown in the figure, in a state where the communication terminal of the present embodiment is powered on, the voice communication mode is started, mode switching is performed by operating the operation unit 105, and the non-voice communication mode or camera mode is executed. It is configured so that each function can be operated.

  In the voice communication mode, reception standby operation for voice and non-voice communication is started. It is possible to have a conversation with the other party by performing an incoming or outgoing voice operation. In the reception standby state, the time and the like are displayed on the second display unit 113 when the casing 101 is closed, and the first display unit 112 when the case 101 is open. The other party's outgoing number is displayed. If the other party's calling number is registered in the phone book in advance together with the name, the other party's name is displayed. Thereafter, by operating the operation unit 105, it is possible to start receiving a call.

  In the non-voice communication mode, the character information input from the operation unit 105 is displayed on the first display unit 112 while maintaining the reception standby state, and is stored in the character information or information recording unit 121 using the transmission function. Sent voice and non-voice (image etc.) information can be transmitted.

  When the character information or voice / non-voice information is received, the information is displayed on the first display unit 112 when the casing 101 is open, and on the second display unit 113 when the casing 101 is closed. A message notifying the reception of is displayed. In addition, character information and image information can be displayed on the first and second display units 112 and 113 by a predetermined operation by the user. Note that when performing voice or non-voice communication, a telephone directory function can be used to determine a transmission partner. In other words, the name of the other party can be displayed on the first display unit 112 using this telephone directory function, and can be selected and confirmed.

  In the camera mode, photographing by the camera unit 109 can be performed in the first open state and the second open state. When the user on the first display unit 112 side is photographed in the first open state, a mirror image is displayed on the first display unit 112, so that the state is the same as when the user is looking at the mirror. In addition, when the user rotates the first casing member 101a to take the person (subject) ahead, the mirror image is displayed on the first display unit 112 and the second display is performed. An inverted mirror image is displayed on the portion 113. Therefore, the user can confirm by viewing the reverse mirror image displayed on the second display unit 113. On the other hand, the person in front of the subject can check how the subject is photographed by looking at the mirror image displayed on the first display unit 112.

  A user who takes a picture can see how the picture is taken by looking at the captured image displayed on the second display unit 113. Further, when it is not desired that the photographed captured image be seen by a person in front, the operation unit 105 is operated to hide the captured image displayed on the first display unit 112 in the second open state. Can be set.

  Further, the captured image can be recorded in the information recording unit 121 as a still image or a moving image. When a moving image / still image recorded in the information recording unit 121 is reproduced, a predetermined operation can be performed to display the captured image on the first display unit 112 for visual observation. This captured image can be stored in the telephone directory in association with the telephone number information. When an incoming call is received from the telephone number associated with the image information, a reverse mirror image of the captured image is displayed on the second display unit 113 when the casing 101 is closed, and the first or second display is displayed when the case 101 is open. Inverted mirror images of the captured images are displayed on the sections 112 and 113. That is, even if a mirror image is displayed at the time of shooting, a reverse mirror image is displayed when a recorded image is read out. In addition, a captured image captured by the camera unit 109 can be transmitted to a communication partner.

  In any mode, when an incoming call arrives, a ring tone is output from the speaker 107 to notify the incoming call. At this time, even if the housing 101 is in the closed state, the ringtone output from the speaker 107 is guided out of the housing 101 via the clearance 123b, so that the user can hear the ringtone clearly. In addition, when the housing 101 is in the open state, the front of the speaker 107 is open, so that it is not difficult for the user to hear the ringtone. Further, when the manner mode is set, the ring tone is not output, and only the vibrator unit 104 operates to vibrate the housing 101 for a predetermined time.

Next, the rotation operation of the housing 101 will be described.
When the closed casing 101 is opened, it rotates about the axis of the first rotation shaft 125. At this time, the number of turns of the first winding part 139b of the flexible substrate 139 is reduced by the amount of rotation of the first rotation shaft bearing 137 that rotates together with the first rotation shaft 125. The bending stress generated in the substrate 139 is also reduced. Since the cable 140 is disposed substantially coincident with the axis of the first rotation shaft 125, the bending stress is not increased or decreased, and only the torsional stress is generated. Further, when the housing 101 returns from the first open state to the closed state, the operation for opening from the closed state is reversed.

  Further, when the first casing member 101a is rotated 180 degrees in the S direction to change from the first open state to the second open state, the number of turns of the second winding portion 139c of the flexible substrate 139 is increased. Increases or decreases the number of windings by the amount of rotation of the second rotation shaft 126. Since the flexible substrate 139 only increases or decreases the number of windings, only the bending stress increases and decreases, and no torsional stress is generated. The cable 140 is wound around the second rotation shaft 126 by the amount that the second rotation shaft 126 is rotated. However, since the second rotation shaft 126 is smaller in diameter than the first rotation shaft 125, the cable 140 is wound. The curvature radius is small, and generation of a large bending stress can be avoided.

  That is, the flexible substrate 139 forms the first and second winding portions 139b and 139c around the axial centers of the first and second rotating shafts 125 and 126. Even if the rotating shafts 125 and 126 rotate, only the curvature and the number of windings of the first and second winding portions 139b and 139c change. Therefore, since the tension and deflection generated in the flexible substrate 139 during rotation are absorbed by the first and second winding portions 139b and 139c, only the bending stress is changed, and the generation of the torsional stress is avoided. .

  When the housing 101 is in the closed state, the first open state, and the second open state, the head of the fastening screw 143 is opposed to the first housing member 101a, and thus the fastening screw 143 is the first housing. It is hidden by the member 101a. Only when the casing 101 is rotated from the first open state to the second open state, the head of the fastening screw 143 is exposed. However, since the user uses the communication terminal under each mode, the user does not operate during the rotation in which the fastening screw 143 is exposed. Therefore, it is possible to avoid deterioration of the appearance quality due to the fastening screw 143 being exposed in the closed state or during normal use (open state). In particular, even if a photograph is published in a magazine, a catalog, or the like, the fastening screw 143 is not reflected, so the design is not impaired.

  In the present embodiment, when the casing 101 is in the closed state, the protrusion 123a for forming the clearance 123b between the first casing member 101a and the second casing member 101b is provided in the second casing. Although formed on the surface of the body member 101b, a projection similar to this may be provided on other parts such as the first housing member 101a. In addition, other methods such as projecting a cover member for concealing a screw for fastening the first casing member 101a from the surface of the first casing member 101a may be used. Note that in order to be able to guide the sound output from the speaker 107 to the outside of the housing 101 even when the housing 101 is in the closed state, the housing facing the housing member provided with the speaker 107 is used. A clearance 123b may be formed between the body member and the body member.

  As described above, according to the open / close communication terminal of the present embodiment, the cover member (the front cover 141 and the rear cover 142) is simultaneously rotated as the first rotation shaft 125 is rotated. The member can always be in close contact with the first rotation shaft 125. Accordingly, since no gap is generated between the first rotation shaft 125 and the cover member during the rotation about the first rotation shaft 125, it is possible to prevent intrusion of rainwater or the like. Further, since the rotation angle of the second rotation shaft 126 is restricted by a member provided inside the first rotation shaft 125, the rotation radius can be reduced, and as a result, the hinge portion 102 can be reduced in size.

  In addition, when the second rotation shaft 126 is rotated 180 degrees from the first open state to the second open state, the first rotation shaft 125 can be prevented from rotating. The hinge-side ridge portion of the first housing member 101a can be prevented from coming into contact with the main surface 101g of the second housing member 101b, and the second housing member 101a can prevent the second housing member 101a from touching the main surface 101g. It is possible to prevent a dent from being given to the main surface 101g of the casing member 101b with a simple structure. In addition, when the first rotating shaft 125 and the second rotating shaft 126 are rotated, a click feeling can be obtained with a simple configuration, so that the user can easily recognize the start and end of the rotation. .

  When the casing 101 is in the closed state and the open state (first open state and second open state), the cover members (the front cover 141 and the rear cover 142) constituting the hinge unit 138 are used as the first rotating shaft 125. Since the head of the fastening screw 143 for fixing is hidden or not exposed, appearance can be improved. Further, since the head of the fastening screw 143 is exposed while the first casing member 101a is being rotated, the cover member can be easily removed. Further, a user holding the communication terminal can check by looking at the reverse mirror image displayed on the second display unit 113, while the person in front of the subject is photographed how It can be confirmed by looking at the mirror image displayed on the first display unit 112.

  The open / close type communication terminal according to the present invention is useful as a device having a hinge device with a small gap between the rotation shaft and the cover member or a small hinge device with a small rotation radius of the rotation shaft.
