In portable communication terminals such as telephones, personal handy phone systems (PHS), and the like, folding mobile communication having a second display unit separately from the first display unit so that the display can be seen even when folded. Various terminals have been developed. There are various configurations of such a foldable mobile communication terminal having two display units, but the configuration in which the second display unit is mainly mounted on the opposite surface of the first housing with the first display unit is provided. In many cases. In this case, the first housing with the display unit cannot be made thin due to the thickness of the first and second display units, which increases the thickness of the apparatus main body.

  In order to solve such a problem, a portable communication terminal in which a second display unit is mounted on a hinge unit is conventionally known (see, for example, Patent Documents 1 and 2). In addition, the second display unit is mounted on the back surface of the second housing (the surface opposite to the surface on which the first display unit overlaps when folded), and a foldable mobile phone having two display units. Communication terminals are also conventionally known.

  On the other hand, in a foldable mobile communication terminal in which the first housing and the second housing are rotatably coupled via a hinge portion, the first housing and the second housing are folded on a mating surface. A portable communication terminal that is extended to form an exposed surface and is provided with an LCD display on each of the mating surface and the exposed surface of the first housing is also known (see, for example, Patent Document 3).

  Further, the second casing provided with the transmitter is formed longer than the first casing provided with the receiver, and the second casing is folded in the first state. A foldable portable communication terminal is also known that has a protrusion that protrudes from the housing and a display device on the surface of the protrusion that faces the first housing (see, for example, Patent Document 4). ).

In the conventional mobile phone, the display screen of the first display unit 41 includes a screen area L51 that collectively displays the remaining battery level, the mark indicating the antenna bar, date, clock information, and the like, and various user operations. In many cases, the screen area L52 indicating an image or text is divided into two. Although not shown, the screen area L51 is further divided into two parts, a mark indicating the remaining battery level and antenna bar is displayed at the top of the screen, the date and clock information is displayed at the bottom of the screen, and the screen area L52 is displayed at the center of the screen. It is set as the structure to provide.

  In the screen area L51, a battery level indicator, an antenna bar mark, date, clock information, and the like are displayed. If the user sets various settings, for example, the manner mode setting is present, the mark indicates that the manner mode is set. When the first display unit 41 is on, this mark is always displayed.

  A screen area L52 in FIG. 16 is a screen area showing an image, a text sentence, and the like, and variously changes the contents displayed according to various operations of the user. For example, when creating an email text, an email creation editing screen is displayed in the screen area L52, and when images such as photographs and illustrations are displayed, various images are displayed in this area. As described above, in the conventional mobile phone, the operation information, setting information, etc. of the mobile phone are always displayed in the screen area L51, and the display content of the screen area L52 is changed each time as the user operates. The screen area of the display unit 41 was divided into two.

  In the conventional cellular phone, the first display unit 41 is turned off when the cellular phone is closed, and the information displayed in the screen area L51 is displayed on the second display unit 51. As described above, the length L5 of the first display unit 41 shown in FIG. 15 is composed of the screen area L51 and the screen area L52 shown in FIG. Therefore, the screen area has to be enlarged by the length of the screen area L51 shown in FIG. 16, and as a result, the length L1 of the second casing shown in FIG. 15 is increased. It was. In addition, information to be displayed on the screen area L51 when the mobile phone is opened or closed is displayed on the first display unit 4 or the second display unit 5, and the same content is displayed on each of the two display units. Display efficiency was poor.

  In the present embodiment, the folding mobile phone having two conventional display units can be made thinner than the configuration shown in FIG. 14, and can be made smaller than the configuration shown in FIG. It is for making it possible.

  Next, the operation of the mobile phone as the foldable mobile communication terminal according to the present invention will be described with reference to the drawings. In the description, an example of display contents of the first display unit 41 of the conventional mobile phone will be described with reference to FIG. 1, 2, and 4, the first casing 101 in which the first display unit 4 is disposed on the front surface and the receiver sound hole 7 a (and the receiver 7) is disposed on the front end portion of the front surface, and the front end side of the front surface The second display unit 5 is mounted on the front side, the key input unit 6 is mounted on the front hinge portion, and the microphone sound hole 8a (and the other side of the receiver 7 across the first display unit 4). When the foldable mobile phone 100 in which the second casing 102 in which the microphone 8) is disposed is rotatably coupled by the hinge portion 200, the second display portion 5 is shown in FIG. Information as shown is displayed.

  When the conventional mobile phone is in an open state, the mark displayed on the second display unit 5 shown in FIG. 5 is displayed above or below the screen of the first display unit 41 as shown in FIG. Therefore, it is necessary to increase the screen size of the first display unit 41 by the mark displayed on the second display unit 5 as shown in FIG. 5, which increases the size of the mobile phone body. It was. Alternatively, since both the information of the mark and the image displayed on the second display unit 5 as shown in FIG. 5 are displayed on the first display unit 4 as shown in FIG. I had to display it small.

  Further, conventionally, the display of the second display unit is turned off or the display content is changed based on the detection result of the open state by the open / close detection means simultaneously with the display of the first display unit 41. Both the display control of the display unit 41 and the second display unit must be performed simultaneously, and the development of the control program has been complicated. It is difficult for the user to understand the information as shown in FIG. 5 because the information display location is different from that displayed on the first display unit 41 or the second display unit by opening and closing.

  On the other hand, in the present embodiment, when the open state is established, the first casing 101 and the second casing 102 are respectively rotated in the back direction around the hinge portion 200, whereby the first display Since the unit 4 and the key input unit 6 are exposed, the user can check the display of both the first display unit 4 and the second display unit 5 at the same time, but the control unit 3 shown in FIG. Refers to the detection result of the open state of the open / close detection means 10 and turns on the first display unit 4 to present information to the user, and the image set by the user in advance or not noticed by the user Information on incoming calls, mail reception, schedule notification, etc. is displayed, and the second display unit 5 is not affected by the result of the opening / closing detection means 10 and is shown in the closed state before being opened. The display contents shown in (2) are continuously displayed as they are.

  Accordingly, in the present embodiment, it is not necessary to display the content displayed on the second display unit 5 on the first display unit 4, and thus an area for displaying the display content on the second display unit 5. Is unnecessary, and more information can be displayed with the same display area of the conventional first display unit 41 than in the conventional case, or in the case of the same display contents, it can be displayed larger.

  Conventionally, since the display of the second display unit is turned off or the display content is changed based on the detection result of the open state detected by the open / close detection means, the first display unit 41 and the second display unit However, in the present embodiment, the display content of the second display unit 5 is constant and is difficult for the user. Information such as that shown in FIG. 5 is not displayed on the first display unit 4 or displayed on the second display unit 5 by opening and closing, and the display location of the information is not different. Can display a certain display content.

  Further, as shown in FIG. 5, the display content of the second display unit 5 can be composed of a segment type LCD because it displays a fixed mark such as a mark indicating the remaining battery level or a mark indicating the antenna bar. . In this case, it is only necessary to control the lighting and extinguishing of each segment, and the control circuit 3 and software can be configured easily. In addition to turning on and off the segments, information having multiple meanings can be displayed with a simple configuration by changing the contents of the information by blinking.

  In addition, in a dot matrix type LCD, data in the display memory is accessed when updating the display contents, but noise occurs during data access, affecting the radio characteristics, and the reception characteristics often deteriorate. It was. When the second display unit 5 is composed of a segment-type LCD, there is almost no adverse effect on the wireless characteristics due to such display noise, so that it becomes possible to design a mobile phone having good wireless characteristics.

  Note that the content displayed on the first display unit 4 when in the open state can be variously changed according to the function of the mobile phone 100 or the setting by the user, and an image or the like as shown in FIG. 6 can be displayed. it can. At this time, the user operates the key input unit 6 and operates the mobile phone 100 while viewing the display contents of the first display unit 4 and the second display unit 5 as necessary. At this time, the control unit 3 changes the display content of the first display unit 4 according to the operation of the key input unit 6 from the user, and performs Internet access such as telephone, mail, i-mode, etc. through the key input unit 6. The mobile phone is controlled according to the user operation.

  As described above, even when the cellular phone according to the present invention is in the open state, the display on the second display unit 5 does not depend on the detection result of the open / close detection means 10, and the same information as when the mobile phone is closed is displayed from the same position. Since it can be confirmed, it is easy for the user to understand. In addition, since the mark as shown in FIG. 5 is controlled without being displayed on the first display unit 4 even when it is in the open state, a text sentence using the entire screen size of the first display unit 4, You can see the image.

  Next, the operation when in the closed state will be described. When the mobile phone 100 is carried around, the mobile phone 100 rotates the first housing 101 and the second housing 102 about the hinge portion 200 toward the front, respectively, The display unit 4 and the key input unit 6 are closed so as to face inward. In this closed state, the first housing 101 overlaps the second housing 102, but the broken line A and the first housing on the second housing 102 shown in FIGS. The tip of the body 101 overlaps, and the second display unit 5 is exposed even in the closed state. That is, the display content of the second display unit 5 can be confirmed even in the closed state.

  When the first and second casings 101 and 102 are closed, the open / close detection means 10 detects the closed state. When the closed state detection result of the open / close detection means 10 is input, the control unit 3 turns off the display of the first display unit 4. At this time, the second display unit 5 is not affected by the closed state detection result of the open / close detection means 10 and displays various information only under the control of the control unit 3 and is displayed before the closed state. The contents that were being displayed are displayed as they are.

  As described above, even when the cellular phone 100 according to the present embodiment is in the closed state, the display on the second display unit 5 is not influenced by the open / close detection means 10 and can be confirmed from the same position as in the open state, so that it is easy for the user to understand. That is, regardless of whether the main body 100 is opened or closed, information as shown in FIG. 5 can always be obtained from the same position.

  In addition, when the user carries the mobile phone 100, the user often folds the mobile phone 100. In particular, the user often wears the mobile phone 100 on the waist together with a jacket pocket, a shirt chest pocket, or a holder. In such a case, in the conventional mobile phone, the main body is taken out from the pocket or the holder and the display on the second display unit is confirmed, but in the mobile phone 100 of the present embodiment, the tip of the main body is removed from the pocket or the holder. It is possible to confirm the display on the second display unit 5 simply by putting it out.

  In the description of the present embodiment, the case where the open / close detection means 10 is mounted for display on / off of the first display unit 4 has been described for comparison with a conventional model. When current consumption of the display unit 4 is not a problem, or when a timer is provided for input to the key input unit 6 and the operation by the key input unit 6 and the auxiliary switch 6a from the user is not performed for a certain period of time of timer setting When the display is turned off and the control is performed so that the display is turned on when the operation by the key input unit 6 or the auxiliary switch 6a is performed again by the user, the opening / closing detection means 10 is not provided. You can also.

  As described above, according to the present embodiment, the second display unit 5 is mounted on the second casing 102 instead of the first casing 101 where the first display unit 4 is provided. It is possible to make the casing 101 thinner in the thickness direction. Further, the second display unit 5 is mounted on the tip of the second casing 102 so that the second display unit 5 can be seen even when the second display unit 5 is closed. It is possible to visually recognize the second display unit 5.

  In other words, only one of the indicators can be referred to when opening and closing as in the prior art, and the on / off control and output of each display on the first display unit and the second display unit are simultaneously performed by opening and closing. Since the second display unit 5 is visible when the cellular phone 100 according to the present embodiment is opened and closed, the display of each of the first display unit 4 and the second display unit 5 is turned on / off. It is not necessary to simultaneously perform the off control, and only the on / off control of the display of the first display unit 4 is performed, and it is not necessary to perform the on / off control of the display of the second display unit 5.

  In addition, unlike the conventional mobile phone having the first display unit and the second display unit, the display content of the second display unit is not changed between the closed state and the open state. Since the same information is displayed on the screen 5 at the time of opening and closing, the information (basic battery level, antenna bar, clock information, etc.) that is the basis of the operation of the mobile phone is always displayed on the second display unit 5 without confusion. Obtained from. That is, when the user wants to see the remaining battery level, the user can collect information sensuously as if he / she looks at the second display unit 5, so there is an effect that information can be reliably transmitted to the user.

  In addition, since the first display unit 4 and the second display unit 5 are mounted on the faces that face each other when they are closed, both the first display unit 4 and the second display unit 5 are opened when the hinge unit 200 is opened. Can be confirmed, and a large amount of information can be provided to the user.

  Regardless of whether the main body 100 is opened or closed, the second display unit 5 always displays a mark that is the basis of the operation of the mobile phone 100, and the first display unit 4 displays the mark on the second display unit 5. The same contents are not displayed, and the display contents of the first display unit 4 and the second display unit 5 are completely shared, so all the screens of the first display unit 4 are used, Images, mail contents, applications, and information can be displayed.

  Or since the display content of the 1st display part 4 and the 2nd display part 5 is completely shared, according to opening and closing, a 1st display part and a 2nd display part have a battery remaining amount, a clock, etc. Compared with a conventional mobile phone that switches information, the number of display dots of the first display unit 4 can be reduced, and the length can be shortened by the display area used for information such as the remaining battery level and clock. . That is, since the length of the screen area L51 shown in FIG. 16 is not necessary, the length of L5 shown in FIG. 15 can be shortened, and the length of the first housing 101 can be shortened. That is, since the length of the first casing 101 is shortened, the length of the second casing 102 can be shortened, and the total length of the cellular phone 100 can be shortened, so that the cellular phone is thinner and smaller than the conventional model. Is possible.

  Further, in a mobile phone that changes the display content of one display unit between a closed state and an open state, such as a conventional mobile phone having two display units, both the two display units are provided by the open / close detection means 10. There is a problem in the development and design that the display control must be performed, the development of the control circuit and software is complicated, and the design verification of the operation by switching the display of the two display units takes a lot of man-hours. In the mobile phone 100 of the present embodiment, the mark that is always displayed in the operating state of the mobile phone 100 is displayed on the second display unit 5, and the one that changes the display content according to the user operation is the first display unit. 4, the display content is shared, and the display content of the second display unit 5 is not changed by the opening / closing operation. There is no need to perform display control of the display unit 5, development of the control circuit and software is simplified, and design verification of operation by display switching between the first display unit 4 and the second display unit 5 is not required. A great effect can be obtained in terms of design. Since the development cost can be reduced, the price of the apparatus main body 100 can be reduced, and there is a synergistic effect that the user can be provided at a low price.

  Furthermore, in the actual use scene, when the user carries the main body 100, the user often folds the body 100, especially when the user wears it on the waist with a jacket pocket, a shirt pocket, or a holder. There are many. In such a case, in the conventional mobile phone, the main body 100 is taken out from the pocket or the holder and the second display unit 5 is confirmed. However, in the mobile phone according to the present invention, only the front end portion of the main body 100 is taken out from the pocket or the holder. This makes it possible to check the display portion, and convenience is improved.

  Further, as shown in FIG. 5, the display content of the second display unit 5 displays a fixed mark such as a mark indicating the remaining battery level or a mark indicating the antenna bar. As a result, the second display unit 5 can be configured with low cost and low power consumption. Further, in the case of a segment type LCD, it is only necessary to control the lighting and extinction of each segment, and the control circuit 3 and software can be configured easily. In addition, if information content is changed by blinking in addition to turning on / off the segments, it is possible to display information having a plurality of meanings with a simple configuration.

  In addition, in the case of changing the display contents in a dot matrix type LCD, data in the display memory is accessed, but noise is generated during the data access, which affects the radio characteristics and the reception characteristics often deteriorate. However, in the mobile phone 100 according to the present embodiment, the second display unit 5 can be configured by a segment type LCD, so that it is possible to design without considering radio characteristic deterioration due to noise.

Portions 10a and 10b are provided. The open / close detector 10a and 10b constitute an open / close detector 10.

  The first casing 101 and the second casing 122 are connected by the hinge part 200 so that the first casing 101 and the second casing 122 are rotated around the hinge part 200 to the front and back, respectively. It is configured. The second casing 122 is configured to be longer than the first casing 101 in the longitudinal direction (from the hinge end to the distal end). When folded as shown in FIGS. The broken line A on the body 122 and the tip of the first housing 101 are configured to overlap each other.

  The above configuration is the same as that of the first and second embodiments, but in this embodiment, the second housing 122 is mounted on the second housing 122 as shown in FIGS. This is characterized in that it is configured to be inclined from the broken line A to the tip of the second housing. That is, the second casing front end portion is configured to be inclined obliquely so that the thickness on the broken line A side is equal to or less than the thickness of the main body of the mobile phone 120 and becomes thinner toward the second casing front end portion. It is characterized in that it is.

  The first display unit 4 is mounted on the front surface of the first housing 101, and the second display unit 5 and the key input unit 6 are mounted on the front surface of the second housing 122.

At this time, as shown in FIG. 10 and FIG. 11, the second display unit 5 is arranged on the tip end side with respect to the broken line A on the second housing 122 and is closed around the hinge unit 200. The second display unit 5 is configured not to be covered by the first housing 101 so that the display content of the second display unit 5 can be confirmed in any state during opening and closing.

  Further, as shown in FIGS. 10 and 11, the shape of the front end portion of the second casing 122 is configured to become thinner from the broken line A side toward the second casing end portion, and is inclined. Since the second display unit 5 is mounted in accordance with the surface on which it is mounted, the second display unit 5 is also configured to be inclined with respect to the surface of the key input unit 6. That is, in the closed state as shown in FIG. 11, the second display unit 5 can display not only in the z direction but also in the y direction.

  The first display unit 4 is disposed between the receiver 7 (and the receiver sound hole 7a) and the microphone 8 (and the microphone sound hole 8a). This is because when the user uses the phone as a telephone, the microphone 8 (and the microphone sound hole 8a) approaches the mouth when the receiver 7 (and the receiver sound hole 7a) is applied to the ear, so that the user's voice It is because it can make it easy to pick up. Therefore, the microphone 8 (and the microphone sound hole 8b) is preferably disposed at a position far from the receiver 7 (and the receiver sound hole 7a) in the open state.

  In FIG. 10, the microphone sound hole 8 b is disposed along with the microphone 8 on the hinge part end side between the hinge part end on the front surface of the second housing 122 and the broken line A, but the receiver 7 (and the receiver sound hole). 7a) and the microphone 8 (and the microphone sound hole 8b), the main body of the mobile phone 120 or the first casing 101 and the second casing 122 are configured so that the first display unit 4 is disposed. It can be mounted at any location as long as it does not affect the dimensions. For example, it may be mounted on the front end side of the second casing 122 or on the hinge end side of the front surface of the first casing 101. The distance between the receiver 7 and the microphone 8 is the main body of the telephone. A configuration in which 100 is opened and separated is preferable.

  In FIG. 11, the second display unit 5 is inclined obliquely from the front end of the second housing to the broken line A side with respect to the y direction, and the second display unit 5 is mounted along the inclination. . That is, since the second display unit 5 is inclined obliquely in each of the z direction and the y direction, the display on the second display unit 5 can be confirmed from both the z direction and the y direction.

  When the user carries the mobile phone 120, the user often folds the mobile phone 120. In particular, the user often wears the mobile phone 120 on the waist together with a jacket pocket, a shirt pocket, or a holder. In such a case, in the conventional mobile phone, the main body is taken out from the pocket or the holder and the second display unit 5 is confirmed, but in the mobile phone 120 according to the present invention, only the front end of the main body is taken out from the pocket or the holder. The display from the z direction can be confirmed, and the display from the y direction can be confirmed.

  Although the mounting diagram inside the main body is not shown as the third embodiment, by combining with the second embodiment of the present invention, a component having a large shape or size such as a vibrator motor is mounted on the convex portion. Thus, the main body can be configured while maintaining a reduction in thickness and size.

  In addition to the vibrator motor, various peripheral devices 9 such as a camera and an external memory card may be mounted on the convex portion according to the function of the mobile phone. 1, the wireless circuit 2, the control unit 3, or the like may be mounted.

  As described above, according to the third embodiment of the present invention, the second display unit 5 is mounted on the distal end portion of the second casing so that the second display unit 5 can display even when it is closed. In the second housing 122 configured to be longer than the first housing 101 by the length of the second display portion 5, the front end portion of the front surface of the second housing 122 is connected to the main body in the closed state. Since the second display unit 5 is mounted along the tilt, the second display unit 5 is mounted so as to be slanted so that the thickness is less than the thickness and becomes thinner toward the tip of the second casing. When the surface of the key input unit 6 of the housing 122 is set to the horizontal direction, display contents can be confirmed from both the upward direction (vertical direction) and the horizontal direction (horizontal direction).

  In actual use scenes, when the user carries the mobile phone 120, the user often folds the mobile phone 120, especially wearing a jacket pocket, shirt chest pocket, or holder on the waist. There are many cases. In such a case, in the conventional mobile phone, the main body is taken out from the pocket or the holder and the second display unit is confirmed, but in the mobile phone 120 of the present embodiment, only the front end portion of the main body is taken out from the pocket or the holder. Thus, the second display unit 5 can be confirmed, and the display can be confirmed from both the upward and lateral directions, further improving convenience. In addition, since the tip can be thinned naturally from the portion where the first housing tip and the second housing 122 overlap to the tip when the tip is closed, the design is improved and the tip is inclined. It has the effect of appearing thinner.

(Fourth embodiment)
Next, a fourth embodiment of the present invention will be described in detail with reference to the drawings. 12 and 13 show the configuration of the fourth embodiment of the mobile communication terminal according to the present invention. FIG. 12 shows the internal configuration when the mobile phone 130 of the fourth embodiment is in the closed state. FIG. 13 is a sectional view showing the structure of the second display unit 5. Since the external perspective view and circuit configuration of the mobile phone 130 of the fourth embodiment are the same as those in FIGS. 1 and 3, description thereof will be omitted. In FIG. 12, components having the same functions as those in FIGS. 1, 2, and 3 are denoted by the same reference numerals, and description thereof is omitted. However, although the peripheral device 9 in FIG. 3 is not particularly illustrated in FIG. 12, the peripheral device 9 is arbitrary as long as it does not affect the dimensions of the main body of the mobile phone 130 or the first casing 101 and the second casing 102. Can be implemented in place.

  Since the difference between the present embodiment and the first embodiment is the configuration of the second display unit 50, the different configuration will be described. 12 and 13, the second display unit 50 of the mobile phone 130 according to the present embodiment includes a display 5a ', a screen 5b, a light emitting element group 5c, and a spacer 5d. The display 5a 'is a panel that is die-cut in the form of a fixed mark such as a mark indicating the remaining battery level or a mark indicating the antenna bar. In other words, the display 5a 'is configured such that light passes only through the mark-shaped portion, and the portions other than the mark shape are shielded. For this reason, the display 5a 'is preferably made of a non-transparent material, and the material is not limited as long as light passes through only the mark-shaped portion and other portions than the mark shape are shielded.

  The screen 5b protects the display 5a 'and is generally made of a transparent resin such as plastic or acrylic in a mobile phone. In FIG. 12, the display 5a 'and the screen 5b are shown separately, but the displays 5a' and 5b may be configured as one. The light emitting element group 5c shows the entire elements of the light emitting elements c1 to c0 shown in FIG. 13, and is a light source for display of the second display unit 50 in the fourth embodiment, and is a light emitting element such as a light emitting diode. Consists of. In FIG. 13, the light emitting element group 5c has a structure in which ten light emitting elements c1 to c0 are arranged one-dimensionally. However, a necessary quantity is prepared according to the number of marks on the display 5a ′. The array may be an array other than a one-dimensional linear array.

  The spacer 5d keeps the distance between the light emitting element group 5c and the display 5a ′ constant, protects the light emitting element group 5c and the display 5a ′ from structural interference, and further surrounds the components of the light emitting element group 5c. This is for preventing light leakage. The spacer 5d may be made of any resin as long as it is non-permeable, but it is preferable to use a resin mold. As described above, the second display unit 50 can be configured by the panel and the light emitting diode, etc., which are stamped into the shape of the mark without using a display such as an LCD or an organic EL, and the cost of components can be reduced. Further, when the display unit is composed of an LCD, a clock signal is required for display control. However, in this embodiment, since the LCD is not used as the second display unit 50, the clock for the second display unit is used. No signal is required, noise is reduced, and good radio characteristics are obtained.

  In FIG. 12, the first casing 101 and the second casing 102 are rotatably coupled by a hinge part 200, and the first casing 101 and the second casing 102 are centered on the hinge part 200. When the first casing 101 is turned to the front and closed, the second casing 102 is configured to be longer than the first casing 101, and the broken line A on the second casing 102 and the first casing It is the same as that of 1st Embodiment that it is comprised so that the front-end | tip of the body 101 may overlap.

  At this time, the second display unit 50 is disposed closer to the distal end side than the broken line A on the second housing 102, and the second display unit 50 is not connected to the first display unit 50 even when the cellular phone 130 is closed. The display content of the second display unit 50 can be visually recognized in any state during opening and closing without being covered by the housing 101.

  In general, the LCD is connected to an FPC (Flexible Printed Circuits) for connecting the printed board 301 as an LCD module, and various connectors are used to connect the FPC from the LCD and the printed board. Although the FPC is directly connected to the printed board by thermocompression bonding, it is excellent in portability as a use state of the mobile phone, but is often subject to dropping or impact, and often the FPC and the printed board are not connected. The connection may be disconnected or the connection may be poor, causing problems such as lack of display or no display.

  However, in the mobile phone 130 according to the present embodiment, the second display unit 50 is configured not by the LCD but by the light emitting diodes 5c (c1 to c0) mounted on the panel and the printed board 304, so that the mobile phone 130 may be dropped or shocked. It is strongly reduced that the problem of lack of display or non-display is caused. An electronic circuit component 305 is mounted on the printed board 304.

  In the first embodiment, the date information and the time information may be displayed on the second display 5. However, in the fourth embodiment, the date information and the time information are the first information. In the second display unit 50, information as shown on the display 5a 'in FIG. 13 can be expressed by characters, marks, or the like.

  An example of display content of the second display unit 50 of the mobile phone 130 according to the fourth embodiment is shown in the display 5a 'in FIG. The second display unit 50 always displays the content to provide information to the user regardless of opening and closing. The mark shown as an example of the display in the display 5a ′ of FIG. 13 is a mark a1 indicating the remaining battery level, a mark a2 indicating a call and a call, a mark a3 indicating whether a clock alarm is set, from the left side in the figure. Mark a4 indicating incoming call and missed call, mark a5 indicating presence / absence of message message, mark a6 indicating presence / absence of vibration motor activation setting, mark a7 indicating presence / absence of mail transmission / reception and unread mail, mark a8 indicating presence / absence of schedule setting, manner mode setting A mark a9 indicating presence / absence and a mark a0 indicating an antenna bar (whether or not communication with the base station is possible or a level at which communication is possible) are shown.

  The above is an example of display contents, and if necessary, the number and type of marks to be displayed are selected according to the functions mounted on the mobile phone 130 and peripheral devices, and the operating state of the function is indicated according to the function It can be configured to display a mark.

  Here, the light emitting element group 5c is composed of c1 to c0 as light emitting elements for illumination to the marks a1 to a0, respectively. A part or all of the light emitting element group 5c may be composed of multicolor LEDs. In this case, for example, when indicating the level of the mark a1 indicating the remaining battery level, the indicator is fixed such as level 3 for blue, level 2 for green, level 1 for yellow, level 0 for red, etc. In addition, quantitative information can be added by color.

  Moreover, the content of the information to show may be changed by lighting and blinking, or quantitative information may be added by the blink pattern. Furthermore, quantitative information may be added depending on the intensity of the amount of light whose brightness is changed. In addition, the second display unit 50 may stop the setting information and display detailed information and quantitative information on the first display unit 4.

  Next, the operation of the fourth exemplary embodiment of the present invention will be described. In the display of the second display unit 50 shown in FIG. 13, when the mobile phone is operating and the battery level is sufficient and the communication state with the base station is good, the mark indicating the battery level is displayed. A1 and the mark a0 indicating the antenna bar light up. As the operation at this time, the control unit 3 turns on the light emitting elements c1 and c0, and light from the light emitting elements c1 and c0 is transmitted along the stamped portion of the indicator 5a ′. The mark a1 indicating the quantity and the mark a0 indicating the antenna bar appear to be lit.

  For example, when the manner mode is set by the user, the control unit 3 turns on the light emitting element c9, and light passes through the mark a9 indicating whether or not the manner mode is set on the display 5a ′. A mark a9 indicating the presence / absence lights up.

  When the mobile phone 130 receives an incoming call, the control unit 3 alternately turns on / off the light emitting element c4 at a certain cycle, and the light from the light emitting element c4 is transmitted to the telephone of the display 5a ′. Since it is transparent in the shape of a mark a4 indicating an incoming call and a missed call, the mark a4 indicating a telephone call and a missed call flashes. The user recognizes that there is an incoming call to the mobile phone since the mark a4 indicating the incoming call and the missed call blinks on the display of the second display unit 5.

  In the case where a part or all of the light emitting element group 5c is configured by multicolor LEDs, for example, when c1 is configured by multicolor LEDs, the control unit 3 monitors the remaining battery level of the battery 303. If the remaining battery level is sufficient, control c1 to emit blue light, and if the remaining battery level is low, control to emit red light, and add quantitative information by changing the color.
