Description

  The present invention relates to a stackable mobile phone including a plurality of casings connected to each other so as to be overlapped with each other.

  Conventionally, a foldable mobile phone 2 as shown in FIG. 7 is generally known as a foldable mobile phone capable of folding two housings. The foldable mobile phone 2 is provided with a display surface 12 such as an LCD (Liquid Crystal Display) for displaying output information and a speaker 13 on an inner surface 10 of one housing 4, and an inner surface of the other housing 6. 14 is provided with a main operation section 17 and a microphone 15.

  The main operation unit 17 includes a cross key 18 that can be used to indicate an up / down / left / right direction so that an item displayed on the display surface 12 can be selected, a numeric keypad 20 that can input numbers and characters, Various other keys are arranged.

  However, in the foldable mobile phone 2 as shown in FIG. 7, when one housing 4 and the other housing 6 are folded, the display surface 12 can be viewed unless the housing is opened. In the folded state, there is a problem that even if information is output to the display surface 12, it cannot be browsed.

  In order to solve the problem that it takes time and effort to open, there is one in which the display surface 12 faces outward even in a folded state or a state corresponding thereto. As such a cellular phone, for example, there are stacked cellular phones as described in Patent Document 1, Patent Document 2, and Patent Document 3.

  In the state in which the two casings to be connected are opened, the display surface provided in one casing has the outside facing outside when the two casings to be connected are opened. It is suitable. However, unlike the foldable mobile phone 2, it is structured such that one case can be folded and folded while being twisted 180 degrees at the connecting portion of the two cases, so that the two cases are overlapped. Even if it becomes a state, the display surface can face the outside.

  As another conventional overlap type mobile phone, there is one described in Patent Document 4. This stackable mobile phone has one housing provided with a display surface and the other housing provided with an operation unit in a state where the display surface and the operation unit are oriented in the same direction. Are connected by a shaft provided in a direction penetrating the two casings.

  This overlap type mobile phone can be opened by an operation in which one casing expands a fan around the axis with respect to the other casing, and the two casings can be opened with the display surface facing outward. It can be kept in a stacked state.

  Since these two types of cellular phones can be in a state where the two casings are overlapped so that the display surface faces outward, the two casings are output on the display surface while being overlapped. Information can be browsed, but when making a call, as in the case of the folding cellular phone 2, the two cases are opened.

On the other hand, the stackable mobile phone described in Patent Document 5 can browse the information output on the display surface while the two casings are stacked, and the two casings are stacked. You can now make a call.
JP-A-11-215218 Japanese Patent Laid-Open No. 2002-141984 JP 2002-135380 A JP-A-7-288860 JP 2000-196720 A

  However, with the techniques disclosed in Patent Document 1, Patent Document 2, Patent Document 3, and Patent Document 4, when there is an incoming call, it is not possible to make a call unless two housings are opened.

  For this reason, it takes time to make a call, and when it is late to notice the incoming call, it cannot make the call ready before the other party hangs up, making the other person unpleasant. The convenience as a mobile phone could not be fully satisfied.

  On the other hand, according to the technique disclosed in Patent Document 5, a call can be made even in a closed state, so that a call can be immediately made, but the size is reduced in the closed state. When the length of the mobile phone is short and the speaker is brought close to the user's ear, the microphone does not reach the user's mouth.

  Therefore, the present invention can immediately make a call possible even in a closed state in which the two casings are overlapped, and the user feels uncomfortable because the microphone does not reach the mouth during the call. It is an object of the present invention to provide a non-stackable mobile phone.

  In order to solve the above problems, the present invention is such that at least a first housing having a display unit and a speaker and at least a main housing and a second housing having a microphone are connected to each other so as to be openable and closable. The display unit is closed by the first housing in the state and exposed to the outside in the open state, and both the display surface of the display unit and the speaker are arranged on one surface of the first housing and are closed. An overlap type mobile phone that can be exposed to the outside in either of the open state and the open state, and is capable of making a call in the closed state, and from the closed state to the open state. A call control unit is provided for controlling the microphone sensitivity in the closed state in the closed state, and in the open state, the call control unit performing control to decrease the sensitivity of the microphone. Opposing each other in the second housing At least one auxiliary operation unit on a surface other than the first control unit, and the call control unit performs control so as to be off-hook by operation of the auxiliary operation unit when receiving an incoming call in the closed state. The body and the second casing are connected so as to be rotatable about an axis provided in a direction penetrating both casings, and the microphone is an end of the second casing opposite to the axis. And the speaker is arranged to sandwich the display unit together with the first speaker at a position farther from the axis than the first speaker. The call control unit, when off-hooked in the closed state, operates the first speaker so as not to operate the second speaker; Opened Expediently, and controls so that the second and speaker is operated not operated the first speaker.

  According to such an overlap type mobile phone, since it is possible to make a call even in a closed state in which the two casings are overlapped, when there is an incoming call, Without opening the case, it is possible to make a call immediately by operating the auxiliary operation unit. Therefore, even if it is delayed to notice the incoming call, the incoming call can be received before the other party hangs up the call.

  Also, if the microphone does not reach your mouth when talking in the closed state and you feel uncomfortable with the call, after making a call in the closed state or receiving an incoming call, open the phone and lengthen the phone, Since the call can be continued even after the microphone reaches the mouth, the call can be made without a sense of incongruity as in the case of a conventional mobile phone.

  Further, it is preferable that the call control unit controls the call to be disconnected when the call is closed again after the call in the open state. According to such a stacked type mobile phone, when the phone is carried after finishing the call, the call can be disconnected simultaneously with the operation from the open state to the closed state having good portability, thereby improving the operability. be able to.

  In addition, the call control unit performs control to lower the sensitivity of the microphone when the open state is made after the call in the closed state in which the sensitivity of the microphone is increased.

  The first housing and the second housing are connected to each other so as to be rotatable about a plane on a surface that is substantially horizontal to the surfaces facing each other.

  As described above, according to the overlap type mobile phone of the present invention, it is possible to make a call even in a closed state in which the two casings are overlapped. Therefore, when there is an incoming call, like a conventional mobile phone, It is possible to immediately talk by operating the auxiliary operation unit without opening the two housings that have been overlapped. Therefore, even if it is delayed to notice the incoming call, the incoming call can be received before the other party hangs up the call.

  Also, according to the overlap type mobile phone of the present invention, if the microphone does not reach the mouth during the call in the closed state and the call is uncomfortable, the phone is lengthened from the closed state to the open state, Since the call can be continued even after the microphone reaches the mouth, the call can be made without a sense of incongruity as in the case of a conventional mobile phone.

  DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of a stacked mobile phone according to the present invention will be specifically described below with reference to the drawings.

  FIG. 1 to FIG. 6 are diagrams which are referred to for explaining a stacked cellular phone 30 according to an embodiment of the present invention. In the overlap type mobile phone 30 shown in these drawings, the same parts as those of the conventional folding mobile phone 2 are denoted by the same reference numerals, and redundant description of the same configuration as the conventional one is omitted. .

  As shown in FIGS. 1 and 2, the overlap type mobile phone 30 includes a first housing 32 and a second housing 34, and is provided in a direction penetrating the first housing 32 and the second housing 34. Are connected by a shaft 36.

  The stackable mobile phone 30 is configured so that the display surface 12 can be seen from the outside even when the first housing 32 and the second housing 34 are overlapped with each other. The display unit 11 is provided on the opposite surface. In addition, auxiliary operation units are provided on the side surfaces 38 and 40 of the first casing 32 and the second casing 34 so that the first casing 32 and the second casing 34 can be operated even when they are overlapped. A side key 42 and a three-way lever 44 are provided.

  The first housing 32 has a surface on which the display unit 11 is arranged so that the speakers 13a and 13b can hear the sound generated even when the first housing 32 and the second housing 34 are overlapped. Is provided. And the speaker 13a and the speaker 13b are arrange | positioned so that the distance from the axis | shaft 36 may become larger the speaker 13a than the speaker 13b. In the overlap type mobile phone 30 according to the present embodiment, the speaker 13a and the speaker 13b are arranged at positions on both ends of the first housing 32 with the display unit 11 interposed therebetween.

  The microphone 15 is provided at the end of the second housing 34 opposite to the shaft 36. In the present embodiment, the first housing 32 and the second housing 34 are overlapped with each other. In order not to be hidden by one housing, the second housing 34 is provided on the end surface opposite to the shaft 36.

  The stackable mobile phone 30 rotates the first casing 32 by 180 degrees around the shaft 36 as indicated by the arrow a from the state where the first casing 32 and the second casing 34 are overlapped. Accordingly, as shown in FIGS. 3 and 4, the main operation unit 17 provided in the second housing 34 can be opened so that it can be seen outside.

  At this time, since the display surface 12 and the speakers 13a and 13b are rotated in a state of facing substantially the same direction as the main operation unit 17, the display surface 12 can be seen from the outside even when the display surface 12 is opened. The sound emitted from 13b can also be heard.

  Note that the overlap type mobile phone 30 according to the present embodiment has a structure in which the first housing 32 rotates around the shaft 36, but as another embodiment, a rail or the like is provided. It is good also as a structure which the 1st housing | casing 32 slides in the direction shown by the arrow b with respect to the 2nd housing | casing 34 from the state shown in FIG.

  Alternatively, as in the invention described in Patent Document 2 or the like, the first housing 32 and the second housing 34 are connected, and the connecting portion can perform both the folding operation and the twisting operation. It may be structured.

  Therefore, even if the stacked mobile phone has such a structure, as in the stacked mobile phone 30 according to the present embodiment, the state shown in FIGS. 1 and 2 or as shown in FIGS. It can be in a state. For this reason, in the present invention, the state shown in FIGS. 1 and 2 is referred to as an “overlapping state” or a “closed state”, and the state shown in FIGS. 3 and 4 is referred to as an “open state”. . Then, changing from the “closed state” to the “open state” is referred to as an “opening operation”.

  As shown in FIG. 4, the overlap type mobile phone 30 is provided with a camera 46, a mirror 48, and a recording microphone 50 on the back surface thereof, and these can operate even in an open state or a closed state. it can.

  Next, the main operation unit 17, the side key 42, the three-way lever 44, and the like will be described. As shown in FIG. 3, the overlap type mobile phone 30 can operate the cross key 18 and the numeric keypad 20 in the main operation unit 17 provided inside the second housing 34 in the open state. At this time, in order to prevent malfunction, the operation performed by the side key 42 and the three-way lever 44 is invalidated.

  As shown in FIG. 5, the three-way lever 44 used in the closed state can rotate in the upward direction (arrow c direction) and the downward direction (arrow d direction) in the same figure, and in the center direction (arrow e). Direction).

  In the closed state, when the list of destinations and telephone numbers is displayed on the display surface 12 by using the telephone directory function of the overlapping mobile phone 30, the three-way lever 44 is shown in FIG. Can be selected from the list, and when the three-way lever 44 is pushed in the center direction in FIG. You can send to the other party. Further, when there is an incoming call in the closed state, the telephone can be brought into a talking state by pushing the three-way lever 44 in the center direction in the figure.

  Further, the side key 42 shown in FIGS. 1 to 4 can only be pushed. If the call is to be ended while the call is in the closed state, the call can be disconnected by pressing the side key 42.

  FIG. 6 is a circuit diagram of the overlap type mobile phone 30, and various functional units and the display unit 11 denoted by reference numeral 60 are controlled by the control unit 62 to operate. When the main operation unit 17, the three-way lever 44, and the side key 42 are operated, a signal corresponding to the operation is output to the control unit 62.

  In addition, the speakers 13 a and 13 b and the microphone 15 that operate during a call are controlled by the call control unit 63 in the control unit 62. The speakers 13a and 13b are individually controlled by the call control unit 63 so that they can operate independently. Further, the microphone 15 is controlled by the call control unit 63 via the gain adjustment unit 16 to adjust its sensitivity.

  The open / closed state detector 64 shown in this circuit diagram is not shown in FIGS. 1 to 4, but is the first housing 32 and the second housing 34 closed or open? And a signal to that effect is output to the control unit 62.

  As such an open / closed state detection unit 64, for example, a contact point that is brought into conduction by the rotation of the first housing 32 may be provided, or a mechanical switch or a sensor may be provided.

  Next, the operation of the stacked cellular phone 30 will be described.

  When the stacked cellular phone 30 is closed, the open / close state detection unit 64 detects this and outputs a signal to that effect to the control unit 62. To make a call operation in this state, use the telephone directory function to display a list of destinations and telephone numbers on the display surface 12, and then rotate the three-way lever 44 in the vertical direction in FIG. The other party to be called is selected and the three-way lever 44 is pushed in the center direction in the figure to make a call. When an incoming call is received, the three-way lever 44 is pushed in the center direction in FIG.

  When a call state is established by performing a call operation in the closed state or receiving an incoming call, the call control unit 63 in the control unit 62 prevents the speaker 13a from operating, operates the speaker 13b as a receiving unit, and The microphone 15 is operated as a transmitter. Further, since the microphone 15 does not reach the mouth when the speaker 13b is brought close to the user's ear, the call control unit 63 controls the gain adjustment unit 16 to increase the gain in order to increase the sensitivity of the microphone 15.

  When the user feels uncomfortable that the microphone 15 does not reach the mouth during a call in the closed state and performs an opening operation, the open / close state detection unit 64 detects this and the control unit 62 A signal to that effect is output. At this time, the call control unit 63 in the control unit 62 operates the speaker 13a as the receiving unit, operates the microphone 15 as the transmitting unit, and does not operate the speaker 13b. Further, in order to return the sensitivity of the microphone 15 to normal, the call control unit 63 controls the gain of the gain adjustment unit 16 to be lowered.

  When the call is to be terminated in the open state, the closed state is again set, so that the open / close state detection unit 64 detects this and outputs a signal to that effect to the control unit 62. The internal call control unit 63 automatically disconnects the call.

  Note that the overlap type mobile phone 30 according to the present embodiment, like the conventional overlap type mobile phone, in the open state, makes a call by operating the main operation unit 17, receives a call, and disconnects the call. It goes without saying that it can be done. In the closed state, when a call is made or received and a call is made in the closed state, the call can be disconnected by pressing the side key 42.

  In addition, in the overlap type mobile phone 30 according to the present embodiment, the example in which the auxiliary operation unit is disposed on each of the side surfaces 38 and 40 of the first casing 32 and the second casing 34 is shown. The first housing 32 and the second housing 34 are closed in a closed state, such as the surface of the housing 32 on which the display unit 11 is disposed and the end surface of the second housing 34 adjacent to the surface on which the main operation unit 17 is disposed. What is necessary is just to arrange | position on surfaces other than the mutually opposing surface.

  However, in consideration of the operability with one hand in the closed state, the auxiliary operation unit includes the side surface adjacent to the surface on which the display unit 11 of the first housing 32 is disposed and / or the main operation unit 17 of the second housing 34. It is preferable to provide on the side surface adjacent to the surface to be arranged.

  As mentioned above, although the embodiment of the stackable mobile phone according to the present invention has been described, the present invention is similar in technical concept even when the stackable mobile phone is constituted by three or more cases. Needless to say, it can be applied based on the above.
