DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
First Embodiment

A first embodiment of the present invention will be described with reference to FIGS. 1 to 4. FIG. 1 is a perspective view of a portable terminal apparatus; FIG. 2 is a side view of a closed state of the portable terminal apparatus; FIG. 3 is a front view of an opened state of the portable terminal apparatus; and FIG. 4 depicts right rotation (left rotation) of a movable case of the portable terminal apparatus in the opened state.

This portable terminal apparatus 2 is an example of a rotatable and/or openable/closable electronic device that includes a plurality of movable units such as an opening/closing unit and rotating units, and includes a fixed case 4 that is an operation-side case and a movable case 6 that is a display-side case, as shown in FIGS. 1 and 2. A movable arm 8 is attached to the fixed case 4 with a hinge 10 that is an opening/closing unit; a rotation module 12 is attached to the movable arm 8 and acts as a rotation supporting unit; and the movable case 6 is fixed to the rotation module 12. In this case, the movable case 6 can be opened and closed by the rotation around the hinge 10, and the movable case 6 can be rotated by a predetermined angle to the right or left from the center position (reference position of rotation) by the rotation around the rotation module 12.

As shown in FIG. 3, a rotation center Oa of the movable case 6 is established in the vicinity of the hinge 10 and a peripheral edge 14 is formed as a half-circle edge on the movable case 6. The fixed case 4 is disposed with an input operation unit 16 including a plurality of keys such as symbol keys and cursor keys, and the movable case 6 is disposed with a displaying unit 18 that is a displaying unit including an LCD (Liquid Crystal Display) device, etc. The displaying unit 18 is a rectangular shape that has vertical and horizontal sides with different lengths, and displays a vertically elongated vertical screen or horizontally elongated horizontal screen depending on a rotation angle θ (between 0 to 90 degrees to the right or left) of the movable case 6.

Since the portable terminal apparatus 2 includes the hinge 10, the movable case 6 can be opened and closed along with the movable arm 8. That is, the movable case 6 can be closed along with the movable arm 8 as shown in FIG. 1 or can be maintained in an opened state as shown in FIG. 3. As shown in FIG. 4, the movable case 6 can be rotated by the rotation module 12 by a predetermined angle, for example, 90 degrees, around the rotation center Oa to the right (an arrow A) or left (an arrow B) to form an L-shape with the fixed case 4. In the opened state shown in FIG. 4, a is a center position (right/left rotation start point) conforming to the center line of the movable case 6; b is aright rotated position (right rotation end point) of the movable case 6; and c is a left rotated position (left rotation end point) of the movable case 6.

In the opened state of the movable case 6, if the movable case 6 is located at the center position a, the displaying unit 18 can display a vertical screen as shown in FIG. 3; if the movable case 6 is located at the right rotated position b, the displaying unit 18 can display a horizontal screen as shown by solid lines of FIG. 4; and if the movable case 6 is located at the left rotated position c, the displaying unit 18 can display a horizontal screen as shown by dotted lines of FIG. 4.

A controlling method of the portable terminal apparatus will be described with reference to FIGS. 1 to 4 and FIG. 5. FIG. 5 is a flowchart of process procedures that are an example of a controlling method of the portable terminal apparatus.

In this controlling method, it is detected whether the movable case 6 is in the opened state or closed state (step S1) and, in the case of the closed state, the displaying unit 18 displays nothing since the fixed case 4 overlaps the movable case 6 to hide the displaying unit 18 (step S2).

If the movable case 6 is in the opened state (FIG. 3) and the rotation angle of the movable case 6 is zero degrees, the movable case 6 is located at the center position a and the displaying unit 18 displays the vertical screen (step S3).

If the movable case 6 is in the opened state (FIG. 3) and the movable case 6 is rotated to the right or left, based on the detection of the rotation (step S4), the displaying unit 18 displays the horizontal screen depending on the rotated position (step S5).

The vertical or horizontal screen deployed on the displaying unit 18 is controlled to become a screen layout corresponding to a vertically elongated screen display for the vertical screen or a screen layout corresponding to a horizontally elongated screen display for the horizontal screen. The screen layout as used herein generally refers to setting or changing factors such as alignment, arrangement, and direction of display elements such as characters, graphics, images, and icons displayed on the screen.

Therefore, this controlling method includes the following process procedures for displaying the vertical screen or the horizontal screen and changing the screen layout corresponding to each screen, correspondingly to the opening/closing operation of the fixed case 4 and the movable case 6, the rotating operation of the movable case 6, etc.

a) Detection of Opening/Closing or Rotation of Movable Case 6

The movable case 6 is opened and closed with the movable arm 8 and the hinge 10 relative to the fixed case 4. In either the opened or closed state, the movable case 6 can be rotated on the movable arm 8. To change the display form depending on whether the movable case 6 is in the opened state or the closed state and depending on the rotation angle, a open/close sensor 112 (FIG. 13) of a sensor unit 96 detects the opened state or the closed state and rotation sensors 42, 44 (FIGS. 6 and 13) detect the rotation angle θ of the movable case 6.

b) Screen Switching

If the movable case 6 is in the opened state and located at the center position a, the displaying unit 18 displays the vertical screen. If the movable case 6 is rotated to the right rotated position b, the displaying unit 18 displays the horizontal screen, or if the movable case 6 is rotated to the left rotated position c, the displaying unit 18 is switched to the display aspect of the horizontal screen. If the movable case 6 is returned to the center position a from the horizontal screen display position, the displaying unit 18 is switched to the display of the vertical screen. The display aspect of the screen of the display unit 18 is switched based on the open/close detection and the rotation detection by a control program described later.

c) Screen Layout Changing Control

With regard to the vertical or horizontal screens acquired by the above screen switching, the screen display is switched to a vertical screen layout for the vertical screen and switched to a horizontal screen layout for the horizontal screen. In the case of the horizontal screen, the screen display may be switched to a screen layout corresponding to the right side for a right horizontal screen and switched to a screen layout corresponding to the left side for a left horizontal screen. The screen layouts are set and controlled by the control program described later.

A configuration example of the portable terminal apparatus 2 will be described with reference to FIGS. 6 to 12. FIG. 6 is an exploded perspective view of the portable terminal apparatus; FIG. 7 depicts a position of a rotation lock mechanism of the portable terminal apparatus; FIG. 8 depicts a top side of a movable rear-case; FIG. 9 depicts a rear side of a movable arm; and FIGS. 10, 11, and 12 depict a stopper configuration and operation thereof. In FIGS. 6 to 12, the same reference numerals are added to the same portions as FIGS. 1 to 4.

As shown in FIG. 6, the fixed case 4 includes a fixed front-case 20 and a fixed rear-case 22, and a bearing 24 of the hinge 10 is formed on the longitudinal edge of the fixed front-case 20. The bearing 24 is disposed with a bearing hole 26. A fixed substrate, etc., are mounted to the fixed rear-case 22.

The movable case 6 includes a movable front-case 28 and a movable rear-case 30, and the rotation module 12 is attached to a round portion 32 of the movable rear-case 30. A through-hole 36 is formed at a rotation center portion of the rotation module 12 and the through-hole 36 is used to allow cables not shown to pass through.

The movable front-case 28 is disposed with a movable substrate 40, and the movable substrate 40 is disposed with the rotation sensors 42, 44 that detect the rotation direction and the rotation angle θ of the movable case 6.

The movable arm 8 includes an arm 46 and an arm cover 48. To a round portion 50 of the arm 46, the movable rear-case 30 of the movable case 6 is fixed with a fixing means, for example, a plurality of screws 52, along with the above rotation module 12. Bearings 54, 56 of the hinge 10 is formed on the arm 46, and the bearing 24 of the fixed case 4 is inserted into an interval 58 between the bearings 54, 56. A hinge module 60 is a hinge axis reaching the bearing 24 of the fixed case 4 and is inserted and fixed in the bearing 54, and a hinge module 62 also is a hinge axis and is inserted and fixed in the bearing 56. The hinge module 62 may be configured as a cable guide to allow cables not shown to pass through.

The arm 46 of the movable arm 8 is disposed with a plurality of magnets, i.e., three magnets M2, M3, M4, on the same trajectory as the rotation sensors 42, 44 disposed on the movable front-case 28 of the movable case 6. The center position a, the right rotated position b, or the left rotated position c of the rotating movable case 6 is detected by the rotation sensors 42, 44 and the magnets M2, M3, M4.

The arm cover 48 includes a lid 64 that covers the top surface of the arm 46 and covering portions 66, 68 that cover the bearings 54, 56. The lid 64 is bonded to the arm 46 to protect the top surface of the arm 46, and the covering portions 66, 68 cover peripheral walls of the bearings 54, 56 to reinforce and protect the bearings 54, 56.

The hinge 10 includes the bearing 24 of the fixed case 4, the bearings 54, 56 of the movable arm 8, and the hinge modules 60, 62 as above and supports the movable arm 8 on the fixed case 4 in an openable/closable manner (allowing 180-degree opening/closing in this embodiment). The rotation module 12 rotatably supports the movable case 6 on the movable arm 8.

The movable arm 8 rotatably supporting the movable case 6 via the rotation module 12 and the movable case 6 made rotatable on the movable arm 8 by a rotation module 34 are disposed with a rotation lock mechanism 70 (FIG. 7, etc.) that determines the center position, i.e., zero-degree position, of the allowable left/right rotation angles of 90 degrees of the movable case 6 and a stopper mechanism 72 (FIG. 10, etc.) that determines a rotation range of the allowable left/right rotation angles of 90 degrees.

In this embodiment, as shown in FIG. 6, a pin-engaging portion 74 of the rotation lock mechanism 70 is integrally formed with the movable rear-case 30. As shown in FIG. 8, the pin-engaging portion 74 is located outside of the rotation module 12 and projects from the top surface of the movable rear-case 30. A lock pin 76 engaging with the pin-engaging portion 74 is attached to the arm 46 of the movable arm 8 and is disposed within the arm 46 in this embodiment.

As shown in FIG. 9, the rotation lock mechanism 70 is a mechanism for fixing and retaining the movable case 6 rotatably supported via the rotation module 12 by the movable arm 8 at a position conforming to the fixed case 4, i.e., at the center position a. Fixing and retaining of the movable case 6 on the movable arm 8 generate a retaining state that allows a user to recognize the position as a reference position and to the extent that the movable case 6 is not moved unless the user applies a force in the left or right direction with the intention to rotate the movable case 6 and are not assumed to be a lock state that does not allow the movement thereof. The movable case 6 is retained to the extent that the movable case 6 is not rotated by the load of the normal rotating operation.

In this embodiment, to fix and retain the movable case 6 at a position conforming to the fixed case 4, i.e., at the center position a, the rotation lock mechanism 70 is disposed on a virtual center axis 78 (FIG. 7) penetrating the rotation center Oa of the rotation module 12 fixed to the movable arm 8.

As shown in FIG. 10, the stopper mechanism 72 is a configuration that sets the maximum rotation angle of the right/left rotation of the movable case 6, centering on the rotation lock mechanism 70, to stop the movable case 6 at the maximum rotation angle. In this embodiment, the pin-engaging portion 74 is also used as a stopper portion and the stopper surfaces 80, 82 are formed on the pin-engaging portion 74.

For this pin-engaging portion 74, an arc-shaped groove 84 is formed for inserting the pin-engaging portion 74, and stoppers 86, 88 are formed at the ends of the groove 84, coming into contact with the stopper surfaces 80, 82 of the pin-engaging portion 74. Specifically, the stopper surface 80 is applied to the stopper 86 and the stopper surface 82 is applied to the stopper 88 to block the rotation of the movable case 6. The blocking positions are the positions b, c, which are at 90 degrees to the left/right from the center position a.

In such a configuration, when the movable case 6 located at the position shown in FIG. 10 is rotated counterclockwise, the stopper surface 80 of the pin-engaging portion 74 is applied to the stopper 86, which is the end of the groove 84, and the movable case 6 is stopped at the position of 90 degrees counterclockwise (on the observer's right), as shown in FIG. 11. When the movable case 6 located at the position shown in FIG. 10 is rotated clockwise, the stopper surface 82 of the pin-engaging portion 64 is applied to the stopper 88, which is the end of the groove 84, and the movable case 6 is stopped at the position of 90 degrees clockwise (on the observer's left), as shown in FIG. 12.

A circuit configuration of the portable terminal apparatus 2 will be described with reference to FIG. 13. FIG. 13 is a block diagram of an electric circuit of the portable terminal apparatus 2. In FIG. 13, the same reference numerals are added to the same portions as FIGS. 1 to 12.

In addition to a telephone function, an e-mail transmission/reception function, etc., the portable terminal apparatus 2 includes a control function for changing a display form depending on the opening/closing operation of the fixed case 4 and the movable case 6, the rotating operation of the movable case 6, etc.

The portable terminal apparatus 2 includes the input operation unit 16, the displaying unit 18, a CPU (Central Processing Unit) 90, a memory unit 92, a power source unit 94, the sensor unit 96, a radio unit 98, and an acoustic unit 100. The input operation unit 16 includes a plurality of keys and is used to enter telephone numbers and characters for creating e-mail documents, etc. The displaying unit 18 displays the vertical screen or horizontal screen and is switched to different screen aspects and controlled to become a screen layout corresponding to the vertical screen or horizontal screen depending on the opened/closed state and the rotation angle of the movable case 6.

The CPU 90 executes a program in the memory unit 92 to load the detection information and the control information such as loading the input of the input operation unit 16 and the detection signal of the sensor unit 96, to read and write the information of the memory unit 92, and to perform various controls such as the screen control of the displaying unit 18. With regard to the vertical screen and the horizontal screen, the CPU 90 controls the screen layout corresponding to each screen and launches an optimum function for each screen and, in the function corresponding to the vertical screen, the CPU 90 is used for the menu list display, the data list display, the telephone history display, etc., utilizing the spread in the up/down direction of the vertically elongated vertical screen. In the function corresponding to the horizontal screen, the CPU 90 is used for the panoramic display of a camera image, the English text display, the processing thereof, the deployment of television broadcasting reception images, etc., utilizing the spread in the width direction of the horizontally elongated horizontal screen.

The memory unit 92 stores a control program including processes such as execution of functions corresponding to the screen switching, the screen layout switching, and the opening/closing or rotating (screen), other programs, and various data and is a recording medium including an SDRAM (Synchronous Dynamic Random-Access Memory) 102, an execution flash memory 104, and an archive flash memory 106 in this embodiment. The SDRAM 102, the execution flash memory 104, and the archive flash memory 106 are connected to the CPU 90 through a bus 108.

The SDRAM 102 configures a work area, executes the program read and loaded from the archive flash memory 106, and generates calculation processes and control information. The execution flash memory 104 stores various data and constructs a database, etc. The archive flash memory 106 stores various programs such as the OS (Operating System) and control program.

An external memory IF (interface) 110 is connected to an external memory, such as a memory card, and the external memory stores the address data, such as telephone numbers and e-mail addresses, and various contents.

The power source unit 94 includes a battery, a battery charging circuit controlled by the CPU 90, a stabilizing circuit, a power source controlling circuit, etc., and supplies power to various function units such as the radio unit 98.

The sensor unit 96 detects the opening/closing of the movable case 6 due to the movable arm 8, the rotation angle θ (between 0 to 90 degrees to the right or left) and the rotation direction of the movable case 6. Therefore, the sensor unit 96 includes the open/close sensor 112 and the rotation sensors 42, 44. The open/close sensor 112 detects presence of magnetic flux from the magnets M (FIG. 6) to generate detection output that represents whether the movable case 6 is in the opened state or closed state. The rotation sensors 42, 44 are disposed on a movable substrate 40 of the movable case 6, and the disposed positions of the three magnets M2, M3, M4 (FIG. 6) conform to positions on the trajectory of the rotation sensors 42, 44 of the rotating movable case 6.

For example, when located at the center position a (FIG. 3) of the movable case 6, since the rotation sensor 42 overlaps the magnet M2 and the rotation sensor 44 overlaps the magnet M3, the output indicating the center position a of the movable case 6 can be acquired from the rotation sensors 42, 44. At the center position a, for example, the same high-level or low-level output can be acquired from the rotation sensors 42, 44. If the movable case 6 is rotated to the right or left, the magnetic forces from the magnets M2, M3, M4 affecting the rotation sensors 42, 44 are changed, and the rotation sensors 42, 44 generate the output corresponding to the change. The change in the output is generated from the left/right rotation angle θ of 20 degrees and, therefore, represents the rotation direction to the right or left. The output indicating a position of 90 degrees to the right or position of 90 degrees to the left can be acquired from the rotation sensors 42, 44. For example, when the high-level output is acquired from the rotation sensor 42 and the low-level output is acquired from the rotation sensor 44, the output indicates the position of 90 degrees to the right, and when the output is acquired inversely, the output indicates the position of 90 degrees to the left.

The radio unit 98 performs transmission/reception for voice communication or data communication such as e-mail through an antenna 118 and performs the modulation process of voice and data, the demodulation process of voice and data from radio signals, etc.

The acoustic unit 100 outputs received voice through a speaker 120 or captures from a microphone 122 and amplifies voice to be transmitted, etc.

The screen aspect of the displaying unit 18 will be described with reference to FIGS. 14A to 16B. FIGS. 14A and 14B depict a vertical screen display and FIGS. 15A to 16B depict horizontal screen displays. In FIGS. 14A to 16B, the same reference numerals are added to the same portions as FIGS. 1 to 13.

When the movable case 6 is in the opened state, the screen aspect of the displaying unit 18 changes depending on the rotation of the movable case 6, and the vertical screen display (FIGS. 14A and 14B) and the horizontal screen display (FIGS. 15A to 16B) are acquired.

The rotation of the movable case 6 is monitored; the detection information is loaded from the rotation sensors 42, 44 to the CPU 90; and it is determined from the detection information whether the displaying unit 18 is rotated to the right or left (step S12). As shown by solid lines in FIG. 4, if the movable case 6 is rotated to the right, the displaying unit 18 is in the horizontal screen state after the rotation to the right (step S13) and displays, for example, the horizontal screen 152R (FIG. 15A), and the horizontal screen display has the horizontal screen layout.

As shown by dotted lines in FIG. 4, if the movable case 6 is rotated to the left, the displaying unit 18 is in the horizontal screen state after the rotation to the left (step S14) and displays, for example, the horizontal screen 152L (FIG. 16A), and the horizontal screen display has the horizontal screen layout.

When the movable case 6 is rotated from the horizontal screen states (steps S13 and S14) and is returned to the center position a (FIG. 3), the movable case 6 goes to the vertical screen state again (step S11) and displays the vertical screen 124 (FIG. 14A), and the vertical screen display has the vertical screen layout.

In this way, the vertical screen 124 is switched to the horizontal screen 152R or the horizontal screen 152L; the horizontal screen 152R or the horizontal screen 152L is switched to the vertical screen 124; and the screen aspect is changed to the screen layout corresponding to each screen.

With regard to the horizontal screen display of the first embodiment, although the horizontal sub-display fields 156, 158 are located to the left of the horizontal main display field 154 on the horizontal screen 152L as shown in FIG. 16A, the horizontal main display field 154 may be located on the left side and the horizontal sub-display fields 156, 158 may be located to the right of the horizontal main display field 154 to generate a horizontal screen 162L as shown in FIG. 19A. In this case, since the operating area is closer to the input operation unit 16 of the fixed case 4, the input operationality is enhanced.

With regard to the above first embodiment, features will be extracted to refer to operational effects.

The portable terminal apparatus 2 includes a configuration allowing a screen portion, i.e., the displaying unit 18 to be rotated, includes the folding function, and includes a configuration allowing the movable case 6 equipped with the displaying unit 18 to be rotated from the normal vertical screen state by 90 degrees to the left or right.

The rotation and opening/closing of the movable case 6 equipped with the displaying unit 18 are detected by the sensor unit 96, and a function is included to detect whether the displaying unit 18 is rotated to the right or left.

Since the portable terminal apparatus 2 includes a configuration that is rotated from the normal vertical screen state by 90 degrees to the left or right to generated a horizontal screen, when the vertical screen 124 in the opened state is rotated 90-degree to the left or right, not only the character display is rotated 90-degree, but also the screen layout such as arrangement of icons and characters is changed to acquire an easy-to-use screen layout for the horizontal screen display. The horizontal screens 152R, 152L are changed to the vertical screen 124 and an easy-to-use screen layout is acquired for the vertical screen display.

Second Embodiment

A second embodiment of the present invention will be described with reference to FIG. 20. FIG. 20 is a flowchart of a controlling method of the portable terminal apparatus according to the second embodiment.

The portable terminal apparatus 2 according to the second embodiment includes a function of switching the screen display based on detection of the rotation and the rotation direction of the movable case 6 equipped with the displaying unit 18 and, when the vertical screen 124 (FIG. 14A) is rotated to the horizontal screen 152R (FIG. 15A) or the horizontal screen 152L (FIG. 16A) and when the horizontal screen 152R (FIG. 15A) or the horizontal screen 152L (FIG. 16A) is rotated to the vertical screen 124 (FIG. 14A), a convenient function is launched for each screen. Therefore, the portable terminal apparatus 2 according to the second embodiment includes the same configuration as the portable terminal apparatus 2 according to the first embodiment (FIGS. 1 to 4, 6, and 13).

In the controlling method of the portable terminal apparatus 2, as shown in FIG. 20, it is detected whether the movable case 6 is in the opened state or closed state (step S21) and, in the case of the closed state, the displaying unit 18 displays nothing since the fixed case 4 overlaps the movable case 6 to hide the displaying unit 18 (step S22).

When the movable case 6 is operated and goes to the opened state (FIG. 3), a function assigned to the opened state is launched (step S23), and this launch results in the vertical screen state (step S24). In this case, if the rotation angle of the movable case 6 is zero degrees, the movable case 6 is located at the center position a and, for example, the vertical screen 124 is displayed as a vertically elongated vertical screen.

When the movable case 6 is in the opened state (FIG. 3), if the movable case 6 is rotated to the right or rotated to the left, the rotation and the rotation direction, i.e., right rotation or left rotation are detected (step S25).

In the case of the right rotation, the function assigned to the right rotation is launched (step S26) to form the horizontal screen state after the rotation to the right (step S27) and, for example, the horizontal screen 152R is displayed as a horizontally elongated horizontal screen. In the case of the left rotation, the function assigned to the left rotation is launched (step S28) to form the horizontal screen state after the rotation to the left (step S29) and, for example, the horizontal screen 152L is displayed as a horizontally elongated horizontal screen.

This controlling method includes the above procedures such as a) detection of opening/closing or rotation of movable case 6, b) screen switching, and c) screen layout changing control, and the processes are performed to launch the functions assigned to the opened/closed states or the right and left rotations, etc. with the control program depending on the opening/closing and the rotation direction. With the control program, the CPU 90 loads the detection information of the open/close detection and the rotation detection of the sensor unit 96, and the vertical or horizontal screen deployed on the displaying unit 18 is controlled to become the screen layout corresponding to the vertically elongated screen display for the vertical screen or the screen layout corresponding to the horizontally elongated screen display for the horizontal screen.

The function corresponding to the vertical screen is used for the menu list display, the data list display, and the telephone history display, utilizing the spread in the up/down direction of the vertically elongated vertical screen, and the function corresponding to the horizontal screen is used for the panoramic display of a camera image, the English text display, the processing thereof, and the deployment of television broadcasting reception images, etc., utilizing the spread in the width direction of the horizontally elongated horizontal screen.

In the second embodiment, in response to the detection of the rotation and the direction of the screen portion, the function of switching the screen display is launched along with the associated function that is the convenient function for the horizontal screen when the vertical screen is switched to the horizontal screen to reinforce the functionality of the portable terminal apparatus 2.

Third Embodiment

A third embodiment of the present invention will be described with reference to FIGS. 21 to 27. FIG. 21 depicts left/right rotation of the movable case of the portable terminal apparatus in the closed state; FIG. 22 depicts a right sub-screen display example; FIG. 23 depicts a left sub-screen display example; FIG. 24 depicts a horizontal main screen display example; FIG. 25 is a flowchart of a controlling method of the portable terminal apparatus; FIG. 26 is a state transition diagram of display screen mode transition; and FIG. 27 is a flowchart of operation procedures of the portable terminal apparatus. In FIGS. 21 to 27, the same reference numerals are added to the same portions as FIGS. 1 to 20.

This embodiment includes the same configuration as the first embodiment. In this case, as shown in FIG. 21, in the portable terminal apparatus 2, the movable case 6 can be rotated around the rotation center Oa of the rotation module 12 to the right (an arrow A) or left (an arrow B) while the movable case 6 is folded onto the fixed case 4, i.e., in the closed state, and a partial display area 164 of the displaying unit 18 of the movable case 6 can be viewed from backside of the fixed case 4 at the right rotated position b, as shown by solid lines.

Although the display of the displaying unit 18 is cancelled when the movable case 6 is in the closed state, if the movable case 6 is rotated to the right from the center position a, which is the reference position, a right sub-screen 170 can be displayed as shown in FIG. 22, for example. If the movable case 6 is rotated to the left from the center position a, a left sub-screen 172 can be displayed as shown in FIG. 23, for example. Although the right sub-screen 170 and the left sub-screen 172 are the same screen display in this embodiment, these screens may be symmetrically displayed.

On the right sub-screen 170 and the left sub-screen 172, a display area WS is deployed as an area that can be viewed because the area protrudes from the fixed case 4. On the right sub-screen 170 and the left sub-screen 172, an invisible area overlapping the fixed case 4 is defined as a hidden area WB and a visible area protruding from the fixed case 4 is utilized as the display are WS within an entire display area WT of the displaying unit 18. Although the display contents of the right sub-screen 170 and the left sub-screen 172 may be a portion of the display contents of the main display screen, to prevent lack of information, the display area WS displays the display contents identical or similar to the display contents of the main display screen as the right sub-screen 170 and the left sub-screen 172.

While the displaying unit 18 displays the right sub-screen 170 or the left sub-screen 172, if the movable case 6 is opened, the display contents of the right sub-screen 170 or the left sub-screen 172 may be displayed on a horizontal main screen 173 using the entire display area WT, as shown in FIG. 24, for example. The display examples of the sub-screens 170, 172 and the horizontal main screen 173 are illustrative only, and a main screen with changed display contents or other display screens may be displayed.

The right sub-screen 170, the left sub-screen 172, and the horizontal main screen 173 are illustrative only and display a plurality of messages 176 along with the battery mark 132, the radio-wave reception intensity mark 134, a plurality of time displays 138a, 138b, and 138c, and one or more icons 174 representing notification information such as incoming-call information, presence of unread e-mails, and the number thereof. With regard to the time displays 138a, 138b, and 138c, false recognition such as contents recognition changed due to viewing angles is prevented by switching the screen layouts, such as changing the display angle of the same contents, to facilitate visibility and comprehension of the display contents.

A controlling method of this embodiment includes process procedures of displaying the right sub-screen 170 and the left sub-screen 172 as shown in FIG. 25. In this controlling method, it is detected whether the movable case 6 is in the opened state or closed state (step S31) and, in the case of the opened state, the left/right rotation angle is detected and determined (step S32).

In the opened state, if the rotation angle is zero degrees, a vertical main screen (vertical main display mode) is displayed as the above vertical screen (step S33); in the case of the right rotation, a right horizontal main screen (right horizontal main display mode) is displayed as the above horizontal screen (step S34); and in the case of the left rotation, a left horizontal main screen (left horizontal main display mode) is displayed as the above horizontal screen (step S35). In this case, the screen aspect is controlled to become the vertical screen layout correspondingly to the vertical main screen (vertical main display mode) and is switched to the horizontal screen layout for the right horizontal main screen (right horizontal main display mode) or the left horizontal main screen (left horizontal main display mode).

In the closed state, the left/right rotation angle is also detected and determined (step S36). If the rotation angle is zero degrees, nothing is displayed (step S37); in the case of the right direction, the right sub-screen (sub-display mode) is displayed (step S38); and in the case of the left direction, the left sub-screen (sub-display mode) is displayed (step S39).

In the switching of the screen display of the displaying unit 18, as shown in FIG. 26, if the movable case 6 is in the closed state and the rotation angle is zero degrees, the movable case 6 is located at the center position and is in a state 1, and nothing is displayed (ST1). If this non-display state (state 1) is shifted to a state 2 where the movable case 6 is in the opened state and the rotation state is zero degrees, the vertical main display mode is initiated (ST2); if the vertical main display mode is shifted to a state 3 where the rotation state is right rotation, the right horizontal main display mode is initiated (ST3); and if the vertical main display mode is shifted to a state 4 where the rotation state is left rotation, the left horizontal main display mode is initiated (ST4). The screen aspect is switched to the vertical screen layout for the vertical main display mode of the state 2, the horizontal screen layout for the right horizontal main display mode of the state 3, and the horizontal screen layout for the left horizontal main display mode of the state 4 to perform the screen display.

If the non-display state (state 1) is shifted to a state 5 by rotating the movable case 6 to the right or left, the sub-display mode is initiated (ST5). The sub-display mode includes the right sub-display mode and the left sub-display mode depending on the rotation direction.

If the movable case 6 is closed during the state 3 (right horizontal main display mode) or the state 4 (left horizontal main display mode), the state is shifted to a state 5 (sub-display mode).

Since the modes can be switched in this way, when the movable case 6 is in a rotated state, the right horizontal main display mode or left horizontal main display mode can be shifted to the sub-display mode and the sub display mode can be shifted to the right horizontal main display mode or left horizontal main display mode by opening/closing the movable case 6. Specifically, the right horizontal main display mode can be switched to the right sub-display mode, and the left horizontal main display mode can be switched to the left sub-display mode.

The switching of the displaying unit 18 is performed by the control program of the displaying unit 18 as shown in FIG. 27. In the process procedures of the control program, the displaying unit 18 is control to become the non-display state in the state 1 (non-display) (step S41). If the detection information of the opened state is loaded from the open/close sensor 112 (step S42) and the movable case 6 is in the rotation state of zero degrees, the state 1 is shifted to the state 2 to perform the vertical main display mode and, for example, the vertical main screen is deployed on the displaying unit 18 (step S43).

While the vertical main display mode is performed, if the rotation sensors 42, 44 detect the right rotation of the movable case 6 and the detection information is loaded (step S44), the state is shifted to the state 3 to perform the right horizontal main display mode and, for example, the horizontal main screen is deployed on the displaying unit 18 (step S45).

While the right horizontal main display mode is performed, if the open/close sensor 112 detects the closed state of the movable case 6 and the detection information is loaded (step S46), the state is shifted to the state 5 to perform the sub-display mode and, for example, the right sub-screen 170 (FIG. 22) is deployed on the displaying unit 18 (step S47).

In the state 1 (non-display) (step S41), if the movable case 6 is rotated and the left or right rotation detection information is loaded from the rotation sensors 42, 44 (step S48), the state is shifted to the state 5 to perform the sub-display mode and, for example, the right sub-screen 170 (FIG. 22) or the left sub-screen 172 (FIG. 23) is deployed on the displaying unit 18 (step S49).

While the sub-display mode is performed, if the movable case 6 is put into the opened state, which is detected by the open/close sensor 112, and the detection information of the opened state is loaded (step S50), the rotation detection information is acquired from the rotation sensors 42, 44 (steps S44 and S51).

If the detection-information of the left-rotation of the movable case 6 is loaded from the rotation sensors 42, 44 (step S51), the state is shifted to the state 4 to perform the left horizontal main display mode and, for example, the horizontal main screen is deployed on the displaying unit 18 (step S52).

While the left horizontal main display mode is performed, if the rotation detection information indicating zero degrees is loaded from the rotation sensors 42, 44 (step S53), the state is shifted to the state 2 to perform the vertical main display mode and the vertical main screen is deployed on the displaying unit 18 (step S54).

In the process procedures, at step S43, the rotation of the movable case 6 is monitored (step S51); if the detection information indicating the left rotation is acquired from the rotation sensors 42, 44, the process goes to step S52; at step S45, the rotation of the movable case 6 is monitored (step S53); and if the rotation sensors 42, 44 detect the rotation state of zero degrees, the process goes to step S54. At step S50, the rotation of the movable case 6 is monitored (step S44); if the detection information indicating the right rotation is acquired from the rotation sensors 42, 44, the process goes to step S45; at step S52, opening/closing of the movable case 6 is monitored (step S46); and if the detection information indicating the closed state is acquired from the open/close sensor 112, the process goes to step S47.

In such an embodiment, the vertical screen layout can be applied to the vertical screen and the horizontal screen layout can be applied to the horizontal screen to achieve improvement of visibility of the screen contents of the vertically elongated vertical screen and the horizontally elongated horizontal screen, etc.

Fourth Embodiment

A fourth embodiment will be described with reference to FIGS. 28 and 29. FIG. 28 depicts an example of a sub-vertical screen display and FIG. 29 depicts an example of a horizontal screen display. In FIGS. 28 and 29, the same reference numerals are added to the same portions as FIGS. 1 to 27.

In this embodiment, the portable terminal apparatus 2 shown in FIGS. 1 to 4 and 6 to 12 is used. That is, as shown in FIG. 21 (the third embodiment), in the portable terminal apparatus 2, the movable case 6 can be rotated around the rotation center Oa of the rotation module 12 to the right (an arrow A) or left (an arrow B) while the movable case 6 is folded onto the fixed case 4, i.e., in the closed state. As shown by solid lines, the partial display area 164 of the displaying unit 18 of the movable case 6 can be viewed from backside of the fixed case 4 at the right rotated position b.

In the fourth embodiment, by rotating the movable case 6 in the closed state to the right, for example, a sub-vertical screen 178 (FIG. 28) is displayed as a vertical screen, and if the movable case 6 is opened by rotating the movable case 6 around a rotation center Ob of the hinge 10 to a direction of an arrow D, the horizontal screen 152R (FIG. 29) is displayed. In the schedule mode, a vertically elongated display area 164 is displayed on the sub-vertical screen 178 as a vertical screen for the same information, and the display aspect is controlled to become a sub-vertical screen layout. Since the entire displaying unit 18 is exposed on the movable case 6 as shown in FIG. 29 by opening the movable case 6 from the closed state, the horizontally elongated horizontal screen 152R is displayed and the display aspect is controlled to become the horizontal screen layout. In this case, while the sub-vertical screen layout displays only a calendar corresponding to the vertical main display field 126 (FIGS. 14 and 17), the horizontal screen layout displays the horizontal screen 152R (FIG. 15). The contents of the horizontal screen 152R have been described above.

Although the movable case 6 is rotated to the right in this embodiment, the same applies to the left rotation of the movable case 6; the sub-vertical screen 178 as a vertical screen is displayed by rotating the movable case 6 in the closed state to the left; and the horizontal screen 152L (FIG. 16) is displayed by putting the movable case 6 into the opened state. The aspects of the sub-vertical screen layout and the horizontal screen layout are the same as those in the case of the right rotation.
