Description

  The present invention relates to a portable terminal having a plurality of functions including an electronic mail transmission / reception function in addition to a normal call function, and more particularly to a portable terminal that efficiently switches display contents of a display.

  In recent years, a plurality of functions such as an e-mail transmission function, an e-mail reception function, a Web search function for a website, and a photography function are incorporated in addition to a normal call function, such as a recent mobile phone. Mobile terminals are being put to practical use.

  In such a portable terminal, the operator of the portable terminal does not use the above-described functions at the same time. Therefore, an operation mode is assigned to each of the functions described above and provided on the upper surface of the portable terminal body. The desired operation mode is activated with the mode selection key. For example, when the “send mail creation mode” of the e-mail is selected, the “send mail screen” is displayed on the display screen of the display. The operator inputs characters to be transmitted by a combined key operation of a numeric keypad and a cursor key and writes them in the “send mail screen”. When the creation of the transmission text is completed on the transmission mail screen, when the transmission key operation is performed, the generated document is transmitted as an e-mail, and the “transmission mail generation mode” ends.

  In this way, the operator repeats starting, executing, and ending each “operation mode” required by the operator.

  In this case, when “Outgoing mail creation mode” is completed, it automatically switches to “Incoming mail display mode”, “Incoming mail screen” is displayed on the display screen of the display unit, and it shifts to the waiting state for receiving incoming mail. As such, mobile terminals that have been programmed in advance have been put into practical use.

  In this way, in a mobile terminal that can realize a plurality of “operation modes”, for example, when creating an outgoing mail with reference to the incoming mail received by the operator, it is possible to quote and create the incoming mail. You can, but to refer back to the original mail that has been deleted, return the operation mode to "Received mail display mode" and display the received mail on the display screen. It is necessary to copy to the text copy area, change the operation mode to “send mail creation mode”, and paste it to the send mail. Therefore, it is very troublesome for the operator.

  In the portable telephone proposed in Patent Document 1, two independent displays are incorporated, and a plurality of functions can be performed simultaneously. Even if an incoming call in the call mode occurs during the outgoing mail creation operation while looking at the incoming mail, the operator can continue the outgoing mail creation work while making a call.

On the other hand, in the portable terminal proposed in Patent Document 2, switching between the browser (Web search) mode and the e-mail (sending) mode is realized, and the contents of the Web page (Web access result) are switched to the mode during mail creation. Easy to refer to by key operation.

  However, in the mobile phone proposed in Patent Document 1 described above, two independent displays are provided, and a plurality of operation modes can be operated at the same time. Therefore, the mobile phone itself becomes large and complicated. In addition, manufacturing costs will rise significantly. Therefore, it is not practical.

  Moreover, in the portable terminal proposed in Patent Document 2, a mode switching key is provided on the front surface of the portable terminal body, and an operation of switching the display screen of the display device to a transmission mail screen or a Web screen is performed. Therefore, a reply (sending) mail cannot be created while referring to the received mail.

  Therefore, the received mail is displayed on the display screen, and the received mail is separately copied to the text copy area, and the operation mode is changed to “sent mail creation mode” and pasted on the sent mail. However, the fundamental problem of increasing the complexity of the operator or relying on the memory of the operator has not been solved. Furthermore, since the mode switching key is also arranged on the front surface of the portable terminal body along with other keys, it is inevitable that the operation is complicated.

  The present invention has been made in view of such circumstances, such as creating a transmission mail on the same display screen while checking information created in other operation modes such as a received mail on the display screen of the display. It is an object of the present invention to provide a portable terminal that can perform work in other operation modes and can greatly improve operability.

In order to solve the above-mentioned problems, the present invention provides a plurality of control keys and input keys provided on the upper surface of the mobile terminal body, an indicator, and an electronic mail on the outgoing mail screen of the indicator based on the input key operation. In a portable terminal having a send mail creation mode for creating and sending a message and a received mail display mode for displaying the received email on the received mail screen of the display unit,
Outgoing mail display memory that stores the outgoing mail screen created in outgoing mail creation mode, Incoming mail display memory that stores the incoming mail screen selected in incoming mail display mode, and Outgoing mail stored in the outgoing mail display memory Separate display means for splitting the screen and the received mail screen stored in the received mail display memory on the display screen of the display unit, and can be operated simultaneously with a finger different from the top key provided at a position other than the top surface of the mobile terminal body A combined operation unit incorporating a mode switching function for switching between the outgoing mail creation mode and the incoming mail display mode, and a variable setting function of the display area ratio between the outgoing mail screen and the incoming mail screen on the display screen. I have.

  In the portable terminal configured as described above, the screen of each operation mode created on the display screen when set by the mode switching function in the composite operation unit is switched to another operation mode even if the operation mode is created on the display screen. Even if it is stored in the display memory.

  The plurality of stored and held screens are divided and displayed on the display screen of the display. Therefore, by setting the operation mode to the transmission mail creation mode, the transmission mail can be created while referring to the previous received mail. Furthermore, since the display area ratio between the incoming mail screen and the outgoing mail screen can be arbitrarily set by the variable setting function of the composite operation unit, the operability can be further improved.

Further, in another invention, an electronic mail is created on a transmission mail screen of the display based on a plurality of control keys and input keys provided on the upper surface of the mobile terminal body, a display, and an input key operation. In a portable terminal having a transmission mail creation mode to be transmitted and a Web mode in which a Web site is accessed and Web information is obtained and displayed on the Web screen of the display unit,
A transmission mail display memory for storing a transmission mail screen created in the transmission mail creation mode, a Web information display memory for storing a Web screen created in the Web mode, a transmission mail screen stored in the transmission mail display memory, and a Web Sending mail creation that can be operated simultaneously with split display means for splitting and displaying the Web screen stored in the information display memory on the display screen of the display unit, and with a finger different from the top key provided at a position other than the top surface of the mobile terminal A composite operation unit incorporating a mode switching function for switching between the mode and the Web mode, and a variable setting function of a display area ratio between the outgoing mail screen and the Web screen on the display screen.

  In the mobile terminal configured as described above, a plurality of screens (sent mail screens, Web screens) stored and held are divided and displayed on the display screen of the display. Accordingly, by switching the operation mode to the transmission mail creation mode, it is possible to create a transmission mail while referring to the previously searched Web screen. Furthermore, since the display area ratio between the Web screen and the outgoing mail screen can be arbitrarily set by the variable setting function of the composite operation unit, the operability can be further improved.

Furthermore, in another invention, an electronic mail is created on the outgoing mail screen of the display based on a plurality of control keys and input keys provided on the upper surface of the mobile terminal body, the display, and the input key operation. Send mail creation mode to send, received mail display mode to display received e-mail on the received mail screen of the display, and Web to access the website and obtain Web information and display on the Web screen of the display In a mobile terminal having a mode,
Outgoing mail display memory for storing outgoing mail screen created in outgoing mail creation mode, incoming mail display memory for storing incoming mail screen selected in incoming mail display mode, and Web screen created in web mode Web information display memory, received mail screen stored in received mail display memory, outgoing mail screen stored in outgoing mail display memory, and Web screen stored in Web information display memory are divided into display screens of the display unit A split display means for displaying, and a mode switching function for switching between a received mail display mode, a transmitted mail creation mode, and a Web mode, which are provided at positions other than the top surface of the mobile terminal main body and can be operated simultaneously with a finger different from the top surface key Variable display area ratio between incoming mail screen, outgoing mail screen and web screen on the display screen And a composite operation section and the constant function is incorporated.

  In the mobile terminal configured as described above, a plurality of screens (sent mail screen, received mail screen, and Web screen) stored and held are divided and displayed on the display screen of the display. Therefore, by switching the operation mode to the transmission mail creation mode, it is possible to create a transmission mail while referring to the received mail screen received first and the Web screen searched first. Furthermore, since the display area ratio of the received mail screen, the Web screen, and the transmitted mail screen can be arbitrarily set by the variable setting function of the composite operation unit, the operability can be further improved.

  Furthermore, in another invention, in a state in which a plurality of screens corresponding to each mode are divided and displayed on the display screen of the display unit, a region designated portion on one screen is moved to a designated position on another screen. Inter-screen copying means for copying is provided.

  In the mobile terminal configured as described above, for example, in the process of creating a transmission mail, the received mail screen received earlier and a part of the web screen searched earlier are converted into the email being created. Can be used as is. Therefore, the operability can be further improved.

  Furthermore, in another invention, the composite operation section detects a movement of the lever, which is provided so as to be movable in the longitudinal direction of the display and in an orthogonal plane perpendicular to the longitudinal direction, and the movement of the lever. It consists of a lever operation unit consisting of a movement detection unit that switches the mode by switching the movement position of the lever in the orthogonal plane, and is divided and displayed in the long direction of the display screen by the movement operation of the lever in the long direction Move the border of each screen in the long direction.

  In such a composite operation unit, when the lever is moved in the longitudinal direction of the display unit, the boundary of each screen divided and displayed in the longitudinal direction of the display screen moves in the longitudinal direction, and the lever is moved in the orthogonal plane. Since the operation mode is switched when moved by, the operability can be further improved.

  In the present invention, with respect to the display screen of the display device, a plurality of stored and held screens are divided and displayed on the display screen of the display device. Therefore, for example, by switching the operation mode to the transmission mail creation mode, it is possible to create a transmission mail while referring to the previous received mail and Web search information.

(Third embodiment)
9A and 9B are diagrams showing a mobile terminal according to the third embodiment of the present invention. FIG. 9A is an external view, FIG. 9B is a rear view, FIG. 9C is a side view, and FIG. d) is a detailed block diagram. The same parts as those of the mobile terminal of the first embodiment shown in FIG. 1 are denoted by the same reference numerals, and detailed description of the overlapping parts is omitted.

  In the mobile terminal 1 of the third embodiment, a lever operation unit 8 is provided on the back surface 7 of the mobile terminal body 1a as shown in FIG. 9B. A lever 8e that can move in a groove 8a formed in the longitudinal direction of the display 5 is provided. The moving position of the lever 8e in the longitudinal direction is detected by a position detector 8c housed in the groove 8a as shown in the partial sectional view of FIG. Each boundary line 10a, 10b in the display 5 moves in the longitudinal direction corresponding to the movement position in the longitudinal direction of the lever 8e detected by the position detector 8c.

  Further, the lever 8 e has a function of switching the operation mode of the mobile terminal 1. That is, the lever 8e can be tilted in three directions of “left direction”, “center direction”, and “right direction” as shown in FIG. 9D in a plane orthogonal to the moving direction in the groove 8a. Is possible. These three types of tilt states are detected by a three-point switch 8f.

  Specifically, in FIG. 9D, the “received mail display mode” is transmitted from the three-point switch 8f to the operation mode switching unit 14a in a state where the lever 8e is tilted “leftward”. With the lever 8e returned to the “center direction”, the “sending mail creation mode” is transmitted from the three-point switch 8f to the operation mode switching unit 14a. Further, the “Web mode” is transmitted from the three-point switch 8 f to the operation mode switching unit 14 a with the lever 8 e tilted “right”.

  FIG. 10 is a block diagram showing a schematic configuration of the mobile terminal according to the third embodiment. The same parts as those of the portable terminals of the first and second embodiments shown in FIGS. 2 and 7 are denoted by the same reference numerals, and detailed description of the overlapping parts is omitted.

  In the mobile terminal of the third embodiment, at least “call mode”, “received mail display mode”, “transmitted mail creation mode”, and “Web mode” can be selected. As described above, the operation mode switching unit 14a responds when “received mail display mode”, “transmitted mail creation mode”, and “Web mode” are transmitted from the three-point switch 8f of the lever operation unit 8, respectively. Then, the received mail processing unit 16, the transmitted mail creating unit 15, and the Web access unit 23 are activated.

  As shown in FIGS. 9A and 13A, the display control unit 19a includes a received mail screen 9b stored in the received mail display memory 18 and a transmitted mail screen 9a stored in the transmitted mail display memory 14. The web screen 9c stored in the web information display memory 24 is divided and displayed on the display screen of the display 5 with the boundary lines 10a and 10b interposed therebetween.

  The boundary line movement control unit 20a corresponds to the movement position in the longitudinal direction of the lever 8e detected by the position detection unit 8c of the lever operation unit 8 and the operation mode detected by the three-point switch 8f at that time. The longitudinal direction position of the boundary line 10a between the received mail screen 9b and the transmitted mail screen 9a and the boundary line 10b between the transmitted mail screen 9a and the Web screen 9c are moved.

  When the lever 8e is moved in the “received mail display mode”, only the boundary line 10a between the received mail screen 9b and the sent mail screen 9a moves in the same direction as the lever 8e, as shown in FIG. When the lever 8e is moved in the “Web mode”, as shown in FIG. 13C, only the boundary line 10b between the outgoing mail screen 9a and the Web screen 9c moves in the same direction as the lever 8e. Note that the boundary lines 10a and 10b do not move even if the lever 8e is moved in the “sent mail creation mode”.

  Thus, since each boundary line 10a, 10b can be independently controlled on the display screen, for example, the boundary line 10a is moved to the upper end position and the boundary line 10b is moved to the lower end position. Only the outgoing mail screen 9a can be displayed on the display screen. Furthermore, only the received mail screen 9b can be displayed on the display screen of the display 5 by moving both the boundary lines 10a and 10b to the lower end position.

  Similarly, only the Web screen 9c can be displayed on the display screen of the display 5 by moving both the boundary lines 10a and 10b to the upper end position. In addition, the received mail screen 9b and the Web screen 9c can be displayed on the display screen of the display 5 by matching the positions of both the boundary lines 10a and 10b. In other words, the screens 9a, 9b, 9c can be displayed in various combinations on the display screen.

  FIGS. 11 and 12 are flowcharts showing display switching processing for the display 5 performed by the mobile terminal 1 of the third embodiment. When the lever 8e of the lever operation unit 8 is tilted to the left (step Q1), the “sent mail creation mode” and “Web mode” are canceled (step Q2), and the “received mail display mode” is set (step Q3). ). Further, when the lever 8e of the lever operation unit 8 is in the center position (step Q4), the “received mail display mode” and the “Web mode” are canceled (step Q5), and the “sent mail creation mode” is set (step Q6).

  When the lever 8e of the lever operation unit 8 is tilted to the right (step Q7), the “sent mail creation mode” and the “received mail display mode” are canceled (step Q8), and the “Web mode” is set (step Q9). ). Then, the portal website is accessed via the transmission / reception unit 12 (step Q10). The received web screen 9c is displayed on the display 5 and written into the web information display memory 24 (step Q11).
