Description

  The present invention relates to an open / close type mobile terminal device including two cases that can be opened and closed and an imaging unit.

  2. Description of the Related Art Conventionally, mobile terminal devices such as mobile phones that fold a housing provided with a camera have been widely used. Such a portable terminal has a device main unit having a key operation unit, a rotating shaft having a video camera, a monitor for displaying images taken by the video camera, and a user on the front side of the monitor during a videophone call. And a flip unit having a CCD camera. The rotary shaft portion includes an opening / closing shaft that connects the apparatus main body portion and the flip portion so that they can rotate relative to each other (foldable), and a rotary shaft portion that connects the flip portion so as to be rotatable in a lateral direction different from the rotation direction. And have. That is, it can be normally folded, and the flip part can also be rotated in a direction perpendicular to the opening / closing axis (for example, Patent Document 1).

  On the other hand, there has also been proposed a portable terminal device that is not folded but is opened and closed by rotating upper and lower housings. Such a portable terminal device includes a first case having a display means on the front surface and an image pickup means for imaging a rear direction (front of the user) of the display means on the back surface, and a second case having an input means on the front surface. And a rotation shaft that rotatably supports the first case with respect to the second case, and the rotation axis direction is substantially perpendicular to the display surface of the display means. In other words, the imaging means directed in front of the user can take a picture of the scenery in front of the user and display it on a display unit that is directed sideways to the user (for example, patents). Reference 2).

  In recent years, the opening and closing of a camera equipped with a camera that can shoot high-quality images by increasing the diameter of the lens and increasing the number of lenses and reducing the aberration, and increasing the number of pixels in the photoelectric conversion element using a charge imaging element. Mobile terminal devices are gaining popularity.

  However, in the portable terminal device of Patent Document 1, it is desirable to increase the lens diameter in order to improve the performance of a video camera that captures a landscape. However, on the other hand, the video camera has a rotating shaft portion. Therefore, the diameter of the hinge portion is increased, resulting in an increase in the size of the apparatus.

In addition, in the portable terminal device of the above-mentioned Patent Document 2, even if the image pickup unit is improved in performance by increasing the diameter of the lens or the like, an extreme increase in size of the device can be avoided. However, there was a situation that the display part on which the photographed image was displayed could not be seen. In other words, the camera function desired for this type of mobile terminal device is desired to be capable of both taking a photo of the other party and taking a self-portrait. It is preferable that it is directed to the) side so that the photographing situation can be understood.

  The vibrator unit 104 notifies the incoming call by vibration by oscillating the incoming call. The operation unit 105 can be used to switch the sound from the speaker 107 to the operation of the vibrator unit 104 when an incoming call is received.

  The second camera unit 109b is provided on the back surface 101e opposite to the main surface 101d of the second casing member 101b and in the vicinity of the connecting shaft unit 102, and a subject in the rear direction of the operation unit 105 is photographed. It is possible.

  Incident light from the subject captured by the second camera unit 109b passes through the lens group 109c and is converted from an optical signal to an electrical signal by a photoelectric conversion element 109d such as a CCD (charge coupled device), thereby generating image information. Is done. The image information is processed by the image processing unit 118 and then displayed on the display unit 112.

  The image information captured by the second camera unit 109b is recorded in the information recording unit 119 when a predetermined operation is performed.

  In addition, the information recording unit 119 can record telephone number information, voice information, image information other than photographed image information (received image information, etc.), and character information such as mail being created or transmitted / received.

  In the permanent magnet 113 accommodated in the first casing member 101a, the first permanent magnet 113a is provided in the vicinity of the first camera unit 109a, and the second permanent magnet 113b is a lower end of the display unit 112 (the connecting shaft unit 102). Near the right side of the main surface 101c of the first casing member 101a.

  In the Hall element 110 housed in the second casing member 101b, the first Hall element 110a is arranged so as to face the first permanent magnet 113a when the casing 101 is in the second closed state. The housing member 101b is provided at the left corner far from the connecting shaft portion 102. The second hall element 110b is provided at the right corner of the second housing member 101b far from the connecting shaft portion 102 so as to face the first permanent magnet 113a when the housing 101 is in the first closed state. Is provided.

  The third hall element 110c is provided in the vicinity of the connecting shaft portion 102 so as to face the second permanent magnet 113b when the housing 101 is in the first open state. The fourth Hall element 110d is provided in the vicinity of the connecting shaft portion 102 so as to face the second permanent magnet 113b when the housing 101 is in the third open state.

  That is, the first and second Hall elements 110a and 110b pass through the axis A of the connecting shaft portion 102 and the widthwise center of the second casing member 101b when the casing 101 is in the second open state. Are provided at line-symmetric positions. Further, the third and fourth Hall elements 110c and 110d are provided at positions symmetrical with respect to the axis B of the connecting shaft portion 102 when the housing 101 is in the first open state.

  When the housing 101 is in the first closed state, the first permanent magnet 113a is close to the second Hall element 110b. Therefore, the second Hall element 110b detects the magnetism of the first permanent magnet 113a and sends it to the control unit 120. A detection signal is given.

  When the housing 101 is in the second closed state, the first permanent magnet 113a is close to the second Hall element 110b. Therefore, the second Hall element 110b detects the magnetism of the first permanent magnet 113 and sends it to the control unit 120. A detection signal is given.

  If the housing 101 is not in the closed state, the first permanent magnet 113a is separated from the first and second Hall elements 110a and 110b. Since the first and second Hall elements 110a and 110b cannot detect the magnetism of the first permanent magnet 113a, the first and second Hall elements 110a and 110b do not generate a detection signal.

  When the casing 101 is in the first open state, the second permanent magnet 113b is close to the third Hall element 110c. The third Hall element 110c detects the magnetism of the second permanent magnet 113b and sends a detection signal to the control unit 120.

  When the housing 101 is in the third open state, the second permanent magnet 113b is close to the fourth Hall element 110d. The fourth Hall element 110d detects the magnetism of the second permanent magnet 113b and sends a detection signal to the control unit 120.

  If the housing 101 is not in the first and third open states, the second permanent magnet 113b is separated from any of the third or fourth Hall elements 110c and 110d. Since the third and fourth Hall elements 110c and 110d cannot detect the magnetism of the second permanent magnet 113b, the third and fourth Hall elements 110c and 110d do not generate a detection signal.

  When the housing 101 is in the second and fourth open states, the first and second permanent magnets 113a and 113b are separated from any of the first to fourth Hall elements 110a, 110b, 110c, and 110d. Since the first to fourth Hall elements 110a, 110b, 110c, and 110d cannot detect the magnetism of the first and second permanent magnets 113a and 113b, the first to fourth Hall elements 110a, 110b, 110c, and 110d are detected signals. Is not generated.

  Therefore, the control unit 120 opens and closes the first casing member 101a and the second casing member 101b depending on whether or not the detection signals are received from the first to fourth Hall elements 110a, 110b, 110c, and 110d. (The first and second closed states, the first and third open states, and other than these states) can be recognized.

  As described above, the number of permanent magnets 113 is less than that of the Hall element 110, and the arrangement is such that four positions can be detected, thereby reducing the cost. An MR element may be used as the detection sensor. Depending on the component to be selected, the Hall element must be provided in advance so as to face one of the poles of the permanent magnet 113, but if an MR element (an element whose electrical resistance changes as the magnetic material approaches) is used. Since the permanent magnet 113 can be provided so as to face either the S pole or the N pole, the degree of freedom in design is improved.

  Further, the second printed circuit board 114b is accommodated in the second casing member 101b. As shown in FIG. 11, the second printed board 114b is formed with a power feeding portion 114d disposed in the vicinity of the connecting shaft portion 102. One end of the power supply unit 114d is connected to the other end of the cable 111 having one end connected to the conductor pattern 114c, and the other end of the power supply unit 114d is connected to the ground pattern 114e of the second printed circuit board 114b. .

  The conductor pattern 114c and the ground pattern 114e are connected by a cable 111. At this time, the reactive element 114f is loaded between the conductor pattern 114c and the ground pattern to separate the high-frequency coupling between the two.

  Next, the photographing operation by the second camera unit 109b will be described. When the user wants to photograph a person in front, the housing 101 is set in the first open state, the second housing member 101b below the first housing member 101a is held, and the second camera unit 109b is moved forward. Shoot toward the subject.

  In this case, a horizontally-captured captured image is generated and displayed on the display unit 112 that is oriented horizontally (the state in which the longitudinal direction of the display unit 112 is in the horizontal direction) toward the user. That is, the left side of the front landscape is displayed on the left side of the display unit 112, and the upper side of the front landscape is displayed on the upper side of the display unit 112. This is a display suitable for normal viewing in partner shooting in the first open state.

  When the user takes a picture of the user himself (self-photographing), the second casing member 101b is rotated about 180 degrees in the T direction from the first open state about the axis B, and the third In the open state, the second camera unit 109b is pointed toward the user himself / herself and the image is taken. In this case, the display unit 112 is exposed laterally to the right outside of the second casing member 101b, so that the user can shoot while confirming the horizontal captured image generated and displayed on the display unit 112.

  When the control unit 120 detects that the camera is in the third open state, the image processing unit 118 processes the captured image while the second camera unit 109b is capturing, and the display unit displays the left and right of the captured image. Display an inverted mirror image. That is, in the third open state, the left side of itself is displayed on the left side of the display unit 112, and the upper side of itself is displayed on the upper side of the display unit 112. This is a display suitable for normal viewing in self-portrait in the third open state.

  It should be noted that when the captured image is recorded in the information recording unit 119 in the first or third open state and then displayed from the information recording unit 119 and displayed on the display unit 112, all are inverted mirror images, that is, the captured image is not inverted. As an image. That is, regardless of the shooting state, when the captured image is reproduced, it is an inverted mirror image, and this is a display suitable for normal viewing at the time of reproduction.

  The operation of the second camera unit 109b can be performed by the operation unit 105. Note that a second operation unit for operating the second camera unit 109b may be provided on the right or left side of the second casing member 101b. However, since these side surfaces have a small area, the number of operation buttons that can be arranged is limited.

  In the cellular phone according to the present embodiment, the other party can be photographed while looking at the operation unit 105 and the display unit 112 in front view, so that a plurality of operation buttons (numbers from 0 to 9, numbers for receiving, ending, etc.) In the operation unit 105 having 15 buttons, a number of functions such as scaling (zoom function) of the second camera unit 109b, adjustment of the shutter speed, adjustment of brightness and color tone are given. It can be easily adjusted and adjusted during shooting.

  Here, in the case of self-portrait, the operation unit 105 is hidden from the user. However, since the distance between the user and the display unit is almost the length of the hand, many functions such as zooming are not required. It is assumed. Therefore, the function to be used is limited to the shutter function. For example, it is not difficult to provide the shutter function to one button of the operation unit 105 hidden from the user and to operate this button. As another aspect, when a button having a shutter function is provided on the side surface of the second casing member 101b, the shutter button can be more easily pressed even in self-portrait.

  Note that in the modes other than the first and third open states, shooting by the second camera unit 109b does not display the display unit 105 suitable for normal viewing (horizontal orientation). Since the direction (vertical direction) faces sideways, it is unsuitable for the photographing mode. That is, the display of the captured image suitable for the normal viewing is limited to be displayed in the first and third open states. In the closed state, the operation of the camera unit 109 is prohibited.

  In the first and third open states described above, when the second casing member 101b is held on the lower side, the rectangular display unit 112 is long in the left-right direction and horizontally long, so that a VGA (Video Graphics Array) is used. This is suitable for displaying a size image. Therefore, in the first and third open states, the captured image is displayed over the entire area of the horizontally long display unit 112. That is, in the first and third open states, it is possible to display a larger image than when the display unit having the same size is set in the vertically long direction.

  In the third open state, the captured image generated on the display unit 112 oriented in the same direction as the second camera unit 109b is a mirror image. That is, when taking a selfie, the horizontal direction is reversed, but the vertical relationship is not reversed. Since the captured image displayed on the display unit 112 is the same as when the user is looking in the mirror, it is possible to easily determine how the image is reflected, for example, when the neck is tilted.

  Note that when the image recorded in the information recording unit 119 is called out and displayed on the display unit 112, it is displayed as an inverted mirror image regardless of the state of the casing 101 at the time of shooting. That is, at the time of shooting with a minimum of image processing, the playback of the shot image is a display suitable for normal viewing.

  The antenna 103 is disposed in the antenna mounting portion 101f in the vicinity where the connecting shaft portion 102 of the second casing member 101b is mounted. The antenna mounting portion 101f is formed at the tip of the second housing member 101b (one short side of the second housing member 101b) that does not overlap the first housing member 101a in the closed state.

  In the first open state, the user holds the second housing member 101b in his / her hand so that the display unit 112 is turned sideways, and takes a picture with the second camera unit 109b. At this time, when the hand (finger) is held so as to cover the antenna, the user easily notices that the finger covers the second camera unit 109b and normal imaging cannot be performed. Therefore, when the user moves his / her finger below the second camera unit 109b for normal shooting, the antenna mounting unit 101f is not covered at the same time.

  Therefore, a decrease in antenna gain due to covering the antenna 103 with a finger is avoided. In the third open state, the rear surface 101e of the second casing member 101b is directed to the user side, so that the antenna mounting portion 101f is not covered by the hand. FIG. 9 shows a state in which the user grips when photographing, where (a) shows a first open state and (b) shows a third open state.

  As shown in FIGS. 9A and 9C, when the user has the second housing 101b, the user is usually opposite to the short side (herein referred to as the upper side) where the connecting shaft portion 102 is provided. The antenna 103 is provided on the upper side from the portion closest to the lower side of the second camera unit 109b, so that the antenna 103 is covered with a finger. A decrease in gain can be avoided.

  Further, as described above, the first printed circuit board 114a having the conductive pattern 114c is accommodated in the first casing member 101a. Therefore, in the open state with respect to the closed state, the conductive portion of the first printed circuit board 114a is close to the antenna 103. Therefore, the ground condition around the antenna 103 in the housing state changes, whereby the antenna gain of the antenna 103 is changed. May be reduced. Therefore, in this embodiment, in order to avoid a decrease in the antenna gain of the antenna 103 even in the open state, a distance that does not cause a decrease in the antenna gain is ensured, and the first casing member 101a is secured. A predetermined distance L (shown in FIG. 7) is provided.

  In the mobile phone of the present embodiment configured as described above, the first and second closed states are modes when being carried, and are closed compactly and are suitable for portability.

  In the first closed state, the display unit 112 is exposed on the outer surface even in the closed state. For example, when the display unit 112 displays a message for notifying the time or the incoming call, the user can This can be confirmed without opening the body 101. In particular, when the incoming caller's phone number information is displayed, the user can immediately confirm.

  In the second closed state, for example, the user can carry while hiding the display unit 112 on which information that the user does not want to be seen by others (private information, such as incoming call information) is displayed. Accordingly, the user can carry the first or second closed state according to the user's own preference.

  Next, the connecting shaft portion will be described in detail. FIG. 10 is a partially exploded perspective view of the mobile phone according to the embodiment of the present invention.

  In FIG. 10, the connecting shaft portion 102 is attached to a base portion 123 provided on the main surface 101 d of the second casing member 101 b and a base portion 123 provided on the base portion 123 so as to be rotatable in the S direction. And a hollow rotating body 124.

  The base portion 123 includes a cylindrical portion 126 in which a through hole 125 is formed, and an arc-shaped groove portion 128 formed on the surface of the base 127 with the cylindrical portion 126 as a center. An opening 129 (shown by a dotted line) is formed at one end of the rotating body 124, a hinge device 130 is mounted at the opposite end, and a cylindrical rotation restricting portion 131 (shown by a dotted line) and a circular tube are installed on the bottom surface. The part 132 is formed so as to protrude.

  A bearing 133 is attached to the opening 129. The hinge device 130 and the bearing 133 support the first housing member 101a so as to be rotatable in the T direction and the opposite direction. The hinge device 130 generates a click when the first housing member 101a is closed so as to face the second housing member 101b and when the hinge device 130 is opened approximately 180 degrees. A hinge device described in Japanese Patent Application Laid-Open No. 2003-120652 may be provided.

  The rotation restricting portion 131 is slidably fitted in the groove portion 128. When the housing 101 is in the first closed state and the fourth open state, the rotation restricting portion 131 is located at the start end 128 a of the groove portion 128. When the housing 101 is in the second closed state and the second open state, the rotation restricting portion 131 is located at the terminal end 128b of the groove portion 128.

  The operation of the connecting shaft portion 102 will be described when the display portion 112 is exposed on the outer surface. When the first casing member 101a tries to further rotate in the S direction from the second open state, the rotation restricting portion 131 comes into contact with the terminal end 128b, and the first casing member 101a moves in the S direction. The rotation is suppressed. Further, when the first casing member 101a tries to rotate in the direction opposite to the S direction from the first closed state, the rotation restricting portion 131 comes into contact with the start end 128a, and the first casing member 101a The rotation in the direction opposite to the S direction is suppressed.

  Next, a case where the display unit 112 is hidden will be described. When the first casing member 101a tries to rotate in the S direction from the second closed state, the rotation restricting portion 131 comes into contact with the terminal end 128b, and the first casing member 101a rotates in the S direction. The movement is suppressed. Further, when the first casing member 101a tries to rotate in the direction opposite to the S direction from the fourth open state, the rotation restricting portion 131 comes into contact with the start end 128a of the groove portion 128, and the first casing The rotation of the member 101a in the direction opposite to the S direction is suppressed.

  That is, the first housing member 101a can be rotated 180 degrees or less in the S direction in the first closed state, and 180 degrees or less in the opposite direction to the S direction in the second closed state. Can be rotated.

  The cable 111 is connected from the second casing member 101b to the first casing member 101a through the through hole 125, the circular pipe portion 132, the opening 129, and the bearing 133.

  Here, a change in the mode of the cable 111 will be described. When the first casing member 101a rotates in the S direction from the first closed state to the first open state, the cable 111 is substantially between the second casing member 101b and the rotating body 124. A 90 degree twist occurs. Furthermore, when it changes to the 2nd open state, the twist will increase 90 degree | times and will be set to about 180 degree | times. This twist is referred to as an S direction twist.

  When the first casing member 101a rotates in the T direction from the second open state to the second closed state, the cable 111 is substantially between the rotating body 124 and the first casing member 101a. A 180 degree twist occurs. This twist is referred to as a T-direction twist. That is, when the first casing member 101a is reversed, the cable 111 is twisted in the S direction and twisted in the T direction at different positions.

  When the first casing member 101a is rotated from the second closed state in the direction opposite to the S direction to the third opened state, the twist in the S direction is reduced by 90 degrees. Furthermore, when it is rotated 90 degrees, the fourth open state is reached, and the twist in the S direction becomes zero. When changing from the second closed state to the fourth open state, there is no change in the increase or decrease in the twist in the T direction. When changing from the fourth open state to the first closed state, the twist in the T direction becomes zero.

  Here, in the case of a configuration in which a twist in the S direction and the T direction occurs in one place, both torsional and bending stresses are generated in that part. That is, if the stress acts in a composite manner, it is necessary to select an expensive part having a high allowable stress, which causes an increase in cost. However, in the mobile phone according to the present embodiment, the first casing member 101a rotates 180 degrees around the axis A and the axis B, and the first and second closed states, and the first to second states. A housing | casing aspect changes to a 4th open state. That is, the cable 111 can be changed to these six open / closed states with only 180 degree deformation (twisting) at one place. Therefore, the stress acting on the cable 111 may be designed considering only torsional stress.

  Next, the second antenna will be described with reference to the drawings. The second antenna is not provided with a component dedicated to the antenna, but uses a conductive portion included in the first casing 101a and a ground pattern provided in the second casing 101b. FIG. 11 is a diagram for explaining the operating principle of the dipole antenna in the second open state of the mobile phone of the present invention.

  As will be described again, one end of the power feeding unit 114d is connected to the ground pattern 114e and grounded, and the other end is connected to the conductor pattern 113c formed on the first printed board 114 via the cable 111. The power feeding unit 114d is an antenna power feeding unit of the transmission / reception unit 115 formed on the second printed circuit board 114b.

  In the cellular phone configured as described above, a case where the radio frequency is set to 800 MHz (wavelength λ = 375 mm) will be described. When the length L of the conductor pattern 114c and the ground pattern 114e is 90 mm, the conductor pattern 114c and the ground pattern 114e serve as antenna elements and operate as a dipole antenna if the housing 101 is open. ing.

  That is, the conductor pattern 114c and the ground pattern 114e operate as a dipole antenna having about a half wavelength. As a result, the high-frequency current is distributed over a wide area from the tip of the conductor pattern 114c to the tip of the ground pattern 114e.

  As described above, the cellular phone according to the present embodiment is a dipole, in which a portion where a high-frequency current flows is covered with a hand when the second casing member 101b is gripped in a normal usage pattern (open state). The influence on the operation of the entire antenna can be made minute. Therefore, even when the second casing member 101b is held in the hand, deterioration of the antenna gain can be minimized.

  The mobile phone of the present invention also includes the antenna 103 described above. The transmission / reception unit includes a high frequency switch (not shown) and a level determination unit (not shown), the strength of the reception level obtained by each antenna is determined by the level determination unit, and the reception level is determined by the control unit 120. The diversity antenna is realized by selecting the higher antenna.

  As described above, the dipole antenna in the second open state has been described. However, in the open state, the conductive pattern 110c and the ground pattern 110e do not face each other, so there is no component that cancels the high-frequency current. it can.

  Next, the operation of the mobile phone according to the present embodiment will be described with reference to FIGS. 1 to 11, 12, and 13.

  FIG. 12 is an explanatory diagram for explaining functions according to modes of the mobile phone according to the embodiment of the present invention. FIG. 13 is a diagram illustrating an example of a correspondence relationship between a housing mode and a function of the mobile phone.

  In FIG. 1 to FIG. 12, when the mobile phone of this embodiment is powered on, the voice communication mode is started, and 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.

  When the housing 101 is in the first and third open states, it is used when displaying a photographed image photographed by the second camera unit 109b on the display unit 112. In the first open state, the display unit 112 is used to display an image called from a hands-free, videophone, or information recording unit 119. In the second open state, it is used when a character is input or an e-mail is read or used as a normal telephone. When the cellular phone of this embodiment is carried, it is used in the first and second closed states.

  In the voice communication mode, a reception standby operation for voice and non-voice communication is started, and a call can be made with a communication partner by performing an incoming call operation or a outgoing call operation.

  When the case 101 is in a state other than the second closed state in the reception standby state, the time and the like are displayed on the display unit 112, and when the incoming call is received, the display of the time and the like disappears and the other party's transmission number is displayed. If the other party's call number is registered in the phone book in advance together with the name and image, the other party's name and image are displayed. Nothing is displayed when the housing 101 is in the second closed state.

  When a voice-only communication is received, the voice of the communication partner is output from the receiver 106 when the casing 101 is in the second open state and the operation unit 105 is operated to receive the voice. When the state is changed to the first open state during a call, the output of the sound from the receiver 106 is stopped, and the sound is output from the speaker 107, so that hands-free operation can be performed.

  In order to change the case 101 from the closed state to the second open state, the first case member 101a can be simply rotated in the S direction when the case 101 is in the first closed state. When the casing 101 is in the second closed state, the first casing member 101a can be simply rotated in the direction opposite to the T direction. The reception operation can be started by switching to the open state.

  A case where a so-called videophone call with a moving image with sound is received will be described. When an incoming call is received, a normal telephone and a videophone cannot be distinguished. Therefore, when a receiving operation is first performed in the second open state and a receiving operation is performed by the operation unit 105, communication is connected. If a message indicating that it is a videophone call is displayed, when the first open state is set, an image (for example, a face image of the other party) transmitted from the communication partner is displayed on the horizontally long display unit 112 and the received voice is received. Is output from the speaker 107.

  The microphone 108 picks up the voice of the user, the first camera unit 109a takes a picture of the user, and the voice of the user and an image of the picture of the user are transmitted to the communication partner to make a videophone call. At the time of this TV phone call, the user's face usually comes in front of (behind) the mobile phone, and the user's eyes usually correspond to the display unit 112.

  In this state, since the user's face is located in front of the mobile phone, the voice of the other party is directed from the speaker 107 in the vicinity of the display unit 112 toward the front user (the volume is slightly increased). Output in the form). Therefore, the receiver 106 is turned off in the first open state, including hands-free, and the communication partner's voice is output from the speaker 107.

  When it is desired to end a normal telephone call or a videophone call, if the predetermined operation is performed with the operation unit 105 while the housing 101 is in an open state, the call ends. Communication is not interrupted even if the housing mode is changed during normal telephone calls and TV telephone calls. If the other open state is set during a videophone call, the received voice is not output from the speaker 107, and the face image of the other party cannot be said to be suitable for normal viewing such as facing sideways or hiding. The first open state is optimal.

  In the non-voice communication mode, the character information input from the operation unit 105 is displayed on the display unit 112 in the second open state while maintaining the reception standby state, and character information or Audio and non-audio (image etc.) information stored in the information recording unit 119 can be attached and transmitted. The image called at this time is reduced and displayed on a part of the display unit 112.

  When non-voice information such as mail is received, a message for notifying the incoming call is displayed on the display unit 112 in a mode other than the case where the casing 101 is in the second closed state.

  When confirming the content of the received non-speech information, it is possible to display the received character information and image information on the display unit 112 by the second open state and a predetermined operation by the user. At this time, when confirming the image information, the image information is displayed on the display unit 112 in an orientation suitable for normal viewing in the first open state.

  Further, when performing voice or non-voice communication, a telephone directory function can be used to determine a transmission partner. That is, the housing 101 is in the second open state, the operation unit 105 is operated, and the name of the other party and the face image associated with the other party name are displayed on the display unit 112 using the telephone directory function, and are selected and confirmed Can do.

  In the camera mode, shooting by the second camera unit 109b can be performed in the first and third open states.

  When the second camera unit 109b takes a picture in the first open state, a reverse mirror image is displayed on the display unit 112. When the second camera unit 109b takes a picture in the third open state, a mirror image is displayed on the display unit 112. The captured image can be recorded in the information recording unit 119 as a still image or a moving image.

  When a moving image or a still image recorded in the information recording unit 119 is reproduced, the captured image can be displayed on the display unit 112 and visually observed by performing a predetermined operation in the first open state. When the recorded image is called up, a reverse mirror image is displayed regardless of the shooting mode of the casing 101.

  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, the associated captured image is displayed on the display unit 112. If the reverse mirror image is displayed on the display unit 112 at the time of shooting, the same reverse mirror image is displayed on the phone book. When a mirror image is displayed on the display unit 112, a reverse mirror image is displayed on the telephone directory. Further, the captured image captured by the second camera unit 109b can be transmitted as a reverse mirror image to the communication partner.

  That is, the captured image captured by the second camera unit 109b, the received image, and the image called from the information recording unit 119 are displayed as images suitable for normal viewing in the first open state.

  The example of the relationship between the mode and operation of the casing 101 is summarized in FIG. In the present embodiment, the operation unit 105 is provided on the main surface (front surface) 101d of the second housing member 101b, the second camera unit 109b is provided on the back surface, and the display unit 112 is provided on the first surface 101c of the first housing member 101a. The configuration is such that the shooting direction of the second camera unit 109b can be directed forward or in front of the user (on the user's own side) while the horizontal display unit 112 is directed toward the user side. In other words, the display unit 112 is directed toward the user, and the shooting direction of the first camera unit 109b is directed forward or toward the user. Accordingly, the vertical direction of the display unit 112 is not reversed regardless of whether the housing 101 is in the first or third open state.

  A photographed image displayed on the horizontally long display unit 112 can be confirmed while photographing a subject in front or the user himself / herself. At this time, the captured image displayed on the display unit 112 is turned upside down even if the first open state is set during shooting in the third open state or the third open state is set during shooting in the first open state. Therefore, the burden on the image processing unit 118 is not increased.

  In addition, since the diversity antenna is realized by the antenna 103 and the dipole antenna in the open state, the reduction of the antenna gain is minimized while being held. Furthermore, when carrying, the display unit 112 can be closed according to the user's preference, such as hiding or exposing.

  When the housing 101 is in the first open state, the user can hold the second housing member 101b in his hand and make a phone call or handsfree. Further, when an image recorded in the information recording unit 119 is called up, it is displayed on the display unit 112 in the first open state, and when sound is associated with the image at the time of calling (for example, a moving image or the like). Is output from the speaker 107 together with the reproduction of the captured image. That is, the mode in which sound is output from the speaker 107 is limited to the first open state.

  When the housing 101 is in the first and third open states, the second camera unit 109b can take a picture. Shooting by the second camera unit 109b is possible in the second and fourth open states. However, since the captured image is horizontal with respect to the vertically long display unit 112, for example, the first housing member 101a can be grasped with the left hand and the second housing member 101b can be grasped with the right hand. The display unit 112 is not suitable for normal viewing because it is in the horizontal direction. In the closed state, shooting by the second camera unit 109b is prohibited.

  The same operation can be performed when the housing 101 is in the second open state and the fourth open state. In the first and second open states, the received voice is output from the receiver 106 with the output from the speaker 107 turned off. In the second open state, the receiver 106 and the microphone 108 are directed in the same direction, and the distance between them is maximized. Holding the second housing member 101b in the hand and placing the vicinity of the receiver 106 on the head (ear) makes a call so that the microphone 108 comes close to the mouth, so that a clear voice can be heard and transmission can be ensured. .

When used as a normal telephone, the second open state in which the receiver 106 and the microphone 108 face in the same direction is preferable. In the second open state, the caller can be used to select, confirm, and send a call using the telephone directory. Further, characters can be input to read a mail or create a mail.
In the second open state, when the second casing member 101b is held in the hand, the display unit 112 is positioned above the operation unit 105 directed to the user. When searching for a partner or the like, since the hand (finger) of the display unit 112 is not covered, the input operation and operation are easy. Furthermore, the image attached to the mail in the second and fourth open states can be reduced and displayed in a partial area of the display unit 112 before attachment.

  FIG. 14 is a diagram showing an example of a display screen displayed on the display unit in the mobile phone of the present invention.

  FIG. 14A shows the reception standby state. If the case 101 is in a state other than the second closed state, a mark indicating the electric field strength or the remaining electric capacity, date, time, and the like are displayed. In addition, a mark indicating that a mail has arrived or a mark indicating whether or not there is an answering machine may be displayed.

  FIG. 14B shows an image generated on the display unit 112 when the front subject is photographed in the first open state, and the stored image after the image is stored in the information recording unit 119. An image that is called up and displayed on the display unit 112 is displayed, and both display a reverse mirror image of the same subject.

  FIG. 14C shows an image generated on the display unit 112 when the user himself is photographed in the third opened state, and a mirror image of the user is displayed.

  FIG. 14D shows an image generated on the display unit 112 when the stored image is called after the image captured by the user is stored in the information recording unit 119 when the housing is in the third open state. And a mirror image of the user is displayed.

  FIG. 14E shows a display screen when the image captured in FIG. 14B is registered in the phone book, and the face image of the other party is displayed together with the telephone number and the name of the other party. In the phone book, the same reverse mirror image as that at the time of shooting is displayed.

  FIG. 14F shows a display screen when the image captured in FIG. 14C is registered in the phone book, and the face image of the other party is displayed together with the telephone number and the name of the other party. Since the phone book is used in the second open state, the display is suitable for normal viewing when the receiver 106 is set upward. The image registered in the phone book is displayed by rotating the mirror image at the time of shooting.

  When a call is received, the message is displayed when the caller is registered in the phonebook. If the caller's phone number is not registered in the phonebook, a message is displayed to notify that the call has been received, such as “Chaksin”. To do.

  In any mode, when an incoming call arrives, a ring tone is output from the speaker 107 in order to notify the incoming call. When the manner mode is set, the ring tone is not output and only the vibrator unit 104 is operated, and the casing 101 is vibrated for a predetermined time.

  When the casing 101 is in the second closed state, the ring tone output from the speaker 107 is guided to the outside of the casing 101 through the clearance 121a, so that the user can hear the ring tone clearly. When the case 101 is in another mode, the front of the speaker 107 is open, so that it is not difficult for the user to hear the ringtone.

  In particular, when making a videophone, since it is used in the first open state, sound is output toward the user who views the display unit 112, so that a good videophone can be made.

  In this embodiment, when the casing 101 is in the closed state, the protrusion 121 for forming the clearance 121a between the first casing member 101a and the second casing member 101b is provided in the second casing. It was formed on the main surface 101c of the body member 101b. The projection 121 also prevents the first and second casing members 101a and 101b from coming into contact with each other when the projection 121 is closed. In order to provide the first casing member 101a with the projection having the same function as this, it is necessary to provide the projections at predetermined portions on both sides thereof, which may increase the cost. That is, in order to obtain the above effect regardless of the closed state of the housing 101, a clearance forming means for forming the clearance 121a on the housing member facing the housing member on which the speaker 107 is provided is provided. That's fine.

  According to the mobile phone of the embodiment of the present invention as described above, the features on the external shape of the openable portable terminal device in which the upper and lower housings can be opened and closed relatively by the first and second rotations (FIG. 1). To high-quality image taking into consideration the installation of the camera unit, the arrangement of the antenna, the relative arrangement of the camera unit and the display unit, and the setting of an appropriate operation mode corresponding to the open / close state of the housing. The function and the display function of the photographed image can be successfully mounted on the openable portable terminal device, and each mounted function can be used comfortably by the user.

  First, when shooting with the second camera unit 109b, the display unit 112 is basically used in a horizontally long state, and a wide range display can be performed. Moreover, it is possible to take both opponents and selfies. In particular, in the case of a self-portrait, it can be seen as a mirror image, so it is possible to easily determine the image quality.

  In addition, since the vertical relationship of the display unit is not reversed, it depends on various conditions such as the display at the time of shooting, the display direction when the recorded image is called up and displayed after recording the recorded image in the information recording unit, etc. For example, it is not necessary to change the orientation of the image. This reduces the burden on the image processing unit and does not require complicated arrangements. Therefore, since a large captured image can be displayed on the display unit 112 with simple control, a captured image with good visibility can be displayed. Further, when shooting with the other party, the operation unit 105 can be viewed from the front.

  Next, considering the user's comfortable use, the first and third open states are set to a camera mode in which display of a photographed image is permitted. In the first open state, hands-free, videophone, recording On the other hand, the second open state is a mode in which only voice communication other than the TV phone or non-voice communication is performed, and display suitable for normal viewing of the shot image is prohibited. The display for temporarily displaying and browsing the captured image for transmission to the communication partner is excluded.

  That is, when the casing 101 is in the second open state, the user performs a normal conversation with the ear and mouth close to each other, and the display unit 112 is located directly above the operation unit 105, so that character input is possible. Since it is suitable for reading e-mails and the operation of the second camera unit 109b is often unnecessary, shooting is prohibited in the closed state, and the captured image is appropriate in the second and fourth open states. The burden on the image processing unit has been reduced by avoiding the display.

  From this point of view, when the casing 101 is in the second open state, consideration is given so as to allow a comfortable conversation using the receiver 106 and the microphone 108. That is, the voice of the other party is output from the receiver 106, the microphone 108 is provided at a position where the user's voice can be easily picked up, and only the ring tone is output from the speaker 107.

  In addition, since the antenna 103 is disposed above the second camera unit 109b, if it is held so as not to cover the front of the second camera unit 109b, it is inevitably avoided to cover the antenna 103. A decrease in antenna gain is avoided.

  In addition, since the diversity antenna is realized with one antenna and a housing structure, transmission and reception, which is the basic performance of the mobile phone, can be satisfactorily performed while avoiding an increase in cost.

  Further, the display unit 112 can be closed (folded) by exposing or hiding it. Accordingly, the user can select various information displayed on the display unit 112 so that the user can immediately see the information, or a person who does not want to see the information can be hidden and carried.

  In this way, by setting the operation mode in consideration of voice-only communication, non-voice communication (including character input), shooting and playback of the shot image, the open-type mobile phone can capture and display the shot image. It is possible to use it comfortably without overdoing the function. On the other hand, comfortable voice communication is also possible.

  As another example of use, for example, when a TV image is received and an image is displayed on the display unit, the first open state may be displayed in a direction suitable for normal viewing.

  In the present embodiment, a dedicated camera for photographing the user at the time of a videophone call is provided, but this is not necessarily the case. For example, during a videophone call, it should be used in the third open state, and an image captured by the second camera unit may be transmitted to the communication partner. At this time, the voice of the other party is output from the speaker, and if the microphone is provided on the lower end surface of the second casing member, for example, it can pick up sound during both normal telephone calls and videophone calls.

  The openable portable terminal device of the present invention can be equipped with an imaging unit without hindering downsizing of the portable terminal device, and a display unit that displays a captured image in a landscape orientation can be used for both partner shooting and self-portrait. It has a visible effect and is useful for mobile phones and the like.
