Description

  The present invention relates to a portable terminal device and a program which are formed by connecting a plurality of housings constituting a device main body so as to be rotatable by a rotary hinge mechanism.

  In recent years, there are many types of mobile phones with various designs. From the overall shape characteristics, “straight type mobile phone”, “folding type mobile phone”, “slide type mobile phone”, “ It can be classified into “rotary type mobile phones”. In this case, except for the “straight-type mobile phone”, the main purpose is compact storage in consideration of portability, and the form of the telephone body can be changed to a plurality of styles depending on the movable part. For example, in the case of an open / close foldable mobile phone that is currently popular, two styles (closed style and open style) in which the two casings constituting the telephone body are folded and closed are closed. Can be changed.

By the way, conventionally, in a foldable mobile phone that is openable / closable, a mobile phone wireless device that detects a closed style and an open style using a Hall IC and a magnet is known (see Patent Document 1). On the other hand, in the case of a foldable mobile phone, a foldable / rotary (composite) mobile phone is known in which a display housing having a display screen is rotatably attached to a main body housing having a keyboard. (See Patent Document 2).

  However, in the above-described folding / rotating (composite) mobile phone of Patent Document 2, it is determined whether the display screen is reversed by rotating the display housing by 180 ° with respect to the main body housing. For example, when a mechanical switch is used as a means for detection, it becomes difficult to mount at high density and a problem is caused in durability, and a magnetic sensor (Hall element) as described in Patent Document 1 is used. If used, the weak magnetic field magnetized in the surrounding metal part may adversely affect the magnetic sensor and cause malfunction. That is, when the display housing is inverted, the magnetic sensor and the magnet face each other, and the magnetic sensor reacts to turn on its output, thereby detecting the reverse state of the display screen. However, when a magnetic sensor is attached to a metal bracket to maintain the strength of the hinge mechanism connection part (such as a bracket) that allows the main body housing and display housing to rotate, the magnetic sensor and the magnet If the sensor facing is turned on, the metal bracket is magnetized by the magnetic force from the magnet, and even if the display housing is returned from the inverted state to the original state, the magnetic sensor does not turn off and remains on. There was a risk of becoming.

  An object of the present invention is to output a magnetic sensor that reacts when a magnetic sensor and a magnet arranged in the vicinity of a hinge mechanism that rotatably connects a plurality of housings constituting the apparatus main body approach each other. Even if the state of turning on continues, when the magnetic sensor and the magnet are separated from each other, the magnetic sensor can be surely turned off.

  According to the first aspect of the present invention, when a magnetic sensor and a magnet arranged in the vicinity of a hinge mechanism portion that rotatably connects a plurality of housings constituting the apparatus main body approach each other, the magnetic sensor reacts. Turning on, the mobile terminal device detects that the configuration of the device main body has changed from the first style to the second style, and the magnetic sensor and the magnet approach the second style. When changing to the first style by rotating any of the cases via the hinge mechanism, another magnet having a magnetic pole opposite to the magnet is provided at a position approaching the magnetic sensor, When the magnetic sensor approaches the other magnet, the magnetic sensor is configured to be in a non-reactive off state by the reverse magnetic pole.

The invention described in claim 1 may be as follows.
In order to maintain the strength of the portion connecting the hinge mechanism and the housing, the bracket of the hinge mechanism is made of a metal member, and the magnetic sensor is attached to the metal bracket.

  When the display unit having a different aspect ratio in accordance with the change from the first style to the second style or from the second style to the first style is changed from the portrait screen to the landscape screen or from the landscape screen to the portrait screen. Further, display control means is provided for changing the data display direction based on the output from the magnetic sensor that is turned on and off in accordance with the change in the style.

  The main body of the apparatus has a main body housing provided with a key operation unit and a display housing provided with a display unit attached to be openable / closable via a hinge mechanism unit, and the display housing is provided via the hinge mechanism unit. A foldable / rotary apparatus body that is rotatably attached to the main body housing and the display housing in a state in which the main body housing and the display housing are opened via the hinge mechanism, and the main body housing and the display housing. The display housing is moved through the hinge mechanism portion from the state in which the display housing is rotated in the reverse direction through the hinge mechanism portion or the display housing is rotated in the reverse direction with the body open. It can be changed to a style in which the main body case and the display case are overlapped by folding the case (the invention according to claim 4).

  The apparatus main body is a rotary apparatus main body in which a main body housing including a key operation unit and a display housing including a display unit are rotatably attached via a rotary hinge mechanism unit. It is possible to change between a style in which the main body casing is overlapped on the lower side and a style in which one casing is rotated with respect to the other casing via the rotary hinge mechanism ( Invention of Claim 5).

  When a magnetic sensor and a magnet arranged in the vicinity of a hinge mechanism that rotatably connects a plurality of housings constituting the apparatus main body approach the computer, the magnetic sensor reacts and turns on. Thus, it is detected that the form of the apparatus main body has changed from the first style to the second style, and by rotating any of the cases from the second style via the hinge mechanism, the magnet and Detects that the magnetic sensor has changed from the second style to the first style due to the non-reactive off state due to the reverse magnetic pole when the magnetic sensor approaches another magnet with a reverse magnetic pole And a display unit having a different aspect ratio in accordance with the change from the first style to the second style or from the second style to the first style is a portrait screen to a landscape screen. Is a program for realizing a function of changing the display direction of data based on the output from the magnetic sensor that is turned on / off according to the change of the style when the screen is changed from the landscape screen to the portrait screen (claim) (Invention of Item 6)

  According to the first aspect of the present invention, when the magnetic sensor arranged near the hinge mechanism and the magnet approach each other, the magnetic sensor reacts and is turned on so that the first style changes to the second style. In the portable terminal device that detects that the magnetic sensor is changed to the magnetic sensor, when the magnetic sensor and the magnet are changed from the second style in which the magnet is approaching to the first style, the magnet has a magnetic pole at a position that approaches the magnetic sensor. Since the other reverse magnet is provided, even when the magnetic sensor is kept on, the magnetic sensor can be reliably turned off when the magnetic sensor and the magnet are separated. In other words, when the magnetic sensor is changed from the second style to the first style, the magnetic sensor is in an unresponsive OFF state by the reverse magnetic pole, so that it is possible to reliably prevent the malfunction of the sensor, It is also effective against malfunctions caused by external magnetic field effects.

  According to the second aspect of the present invention, in addition to having the same effect as the first aspect of the present invention, since the magnetic sensor is attached to the metal bracket of the hinge mechanism, even if the metal bracket or the like is magnetized, It is possible to reliably suppress adverse effects due to the weak magnetic field. That is, in order to prevent malfunction of the magnetic sensor, it is not necessary to use a non-magnetic material such as a synthetic resin for the bracket of the hinge mechanism, and the strength of the part can be maintained by using a metal.

According to the invention described in claim 3, in addition to the same effect as the invention described in claim 1, the change from the first style to the second style or from the second style to the first style is accompanied. When the display section with a different aspect ratio is changed from a portrait screen to a landscape screen or from a landscape screen to a portrait screen, the display direction of the data is changed based on the output from the magnetic sensor that turns on and off according to this style change. Since the change is made, it is possible to display data in a display mode suitable for a landscape screen and a portrait screen. In this case, the magnetic sensor can be reliably turned on / off according to the style change and is not affected by the external magnetic field, so the data display direction must be changed reliably according to the portrait screen or landscape screen. Is possible.
Note that the invention described in claim 6 has the same effects as those of the invention described in claims 1 and 3.

  In the portable terminal device, a main body housing including a key operation unit and a display housing including a display unit are attached to be able to be opened and closed via a hinge mechanism unit, and the display housing is disposed via the hinge mechanism unit. Further, it may be a foldable / rotary (composite) portable terminal device that is rotatably mounted (invention of claim 4). Further, it may be a rotary type portable terminal device in which a main body casing provided with a key operation unit and a display casing provided with a display unit are rotatably attached via a rotary hinge mechanism unit. Described invention).

Hereinafter, embodiments of the present invention will be described with reference to FIGS.
FIG. 1 is an external view of a folding / rotating (composite type) camera-equipped mobile phone device in this embodiment. FIG. 1 (A) is a front view showing a state in which the device main body is closed, and FIG. It is a front view of the state which opened the apparatus main body.
The apparatus main body is composed of two housings 1 and 2, and a main body housing (lower housing) 1 having a key operation unit 3 and a display housing (upper housing) having a display unit 4. 2 is attached via a hinge mechanism part (connecting part) 5 with a housing.

  The hinge mechanism unit 5 with a casing has a folding structure (open / close hinge mechanism) that connects the main body casing 1 and the display casing 2 so as to be openable and closable, and the display casing 2 with respect to the main body casing 1. It has a rotating structure (rotating hinge mechanism) connected so as to be rotatable by 180 °. In this case, in a state in which the main body housing 1 and the display housing 2 are opened, the display housing 2 is rotated 180 ° via the rotation support shaft 5A constituting the rotation structure of the hinge mechanism portion 5 to thereby display the display portion. It is possible to invert 4 in the reverse direction (back side). When the apparatus main body is opened, the main body housing 1 and the display housing 2 can be opened to 180 ° or a predetermined angle (for example, 135 °).

2A shows a state in which the display housing 2 is rotated 180 ° and the display unit 4 is reversed in the reverse direction (rear side), and FIG. 2B shows the display unit 4 rotated in the reverse direction. It is the figure which showed the state which superimposed the display housing | casing 2 on the main body housing | casing 1 from the state.
The state in which the display housing 2 overlaps the main body housing 1 as shown in FIG. 1A is referred to as “closed style”, and the main body housing is shown in FIG. 1B. 1 and the display housing 2 are opened in the “forward open style”, and the display housing 2 is rotated 180 ° and the display unit 4 is inverted in the reverse direction as shown in FIG. Is called “inverted open style”, and the state in which the display housing 2 is superimposed on the main body housing 1 from the state in which the display unit 4 is reversed in the reverse direction as shown in FIG. 2B is called “view style”. . Here, the “inversion open style” shown in FIG. 2A is a transitional style in the process of changing from the “normal rotation open style” to the “view style”.

  The key operation unit 3 provided in the main body housing 1 corresponds to a menu key 3A for calling a main menu, a mail key 3B for calling a mail menu, and a phone book key 3C for calling a phone book in four directions. In addition to a cursor key 3D for selecting a menu item and the like, a determination key 4E used for determining an item selected by the cursor key 3D, and a start for instructing the start of call transmission / response reception (on-hook) A key 4F, a power on / off key 4G, a numeric key 4H for dial input, numeric value, character input, and the like are provided. In addition, side keys 6 are arranged on both sides of the display housing 2. A photographing lens 7 is provided on the back side of the display housing 2. The magnetic sensor 8 and the magnets 9 and 10 provided in the vicinity of the hinge mechanism unit 5 will be described later.

 The display unit 4 is, for example, a color liquid crystal screen, a high-definition display with different aspect ratios, a standby screen, a menu screen, a mail creation screen, a phone book output screen, a finder screen during camera shooting, and playback of camera images. Functions as a screen. The display unit 4 is used as a portrait screen in the “forward rotation style” shown in FIG. 1B, and is used as a landscape screen in the “view style” shown in FIG. 2B. The data display orientation is changed according to the portrait screen and landscape screen. That is, as shown in FIG. 3 (A), data is arranged and displayed along the short side direction on the vertically long screen, and data is arranged along the long side direction on the horizontally long screen as shown in FIG. 3 (B). Therefore, if the same data is displayed with the same character size and character pitch, the horizontal screen can display a lot of data in the column direction (horizontal direction). A lot of data can be displayed in the row direction (vertical direction).

FIG. 4 is a view for explaining the peripheral portion around the hinge mechanism portion 5 for connecting the main body housing 1 and the display housing 2 so as to be openable and closable and rotatable, and is shown in FIG. As shown, the “inverted open style” state in which the display housing 2 is inverted is shown.
As described above, the hinge mechanism unit 5 includes the open / close hinge mechanism that connects the main body housing 1 and the display housing 2 so as to be openable and closable, and the rotary hinge mechanism that rotatably connects the open / close hinge mechanism and the rotary hinge. Each mechanism operates independently. In addition to being able to rotate the display housing 2 by 180 °, it is of course possible to be able to rotate 360 °, and the rotation direction is not limited to clockwise and counterclockwise, but may be freely rotatable.

  The vertical axis (rotating support shaft) 5A constituting the rotary hinge mechanism and the horizontal axis (opening / closing support shaft) 5B constituting the open / close hinge mechanism are orthogonal to each other, and the open / close support shaft 5B serving as the horizontal axis is the hinge housing. It is housed inside 5C and, for example, is rotatably supported on both side plates of the hinge housing 5C. The rotation support shaft 5A, which is the vertical axis, has a lower end portion fixed to a bearing member 5D provided inside the hinge housing 5C, and a bracket on the upper end portion that stands up from the center portion of the bearing member 5D. 5E is rotatably attached. On the contrary, the lower end portion of the rotation support shaft 5A may be rotatably attached to the bearing member 5D, and the bracket 5E may be fixedly attached to the upper end portion.

  The bracket 5E is provided with mounting plates 5E1 and 5E2 for fixing the lower end portion of the display housing 2 to the left and right of the rotating support shaft 5A by means such as screws. In this case, in this embodiment, a bracket made of metal (made of a magnetic material such as iron) is used to maintain the overall strength including the mounting plates 5E1 and 5E2. Of the mounting plates 5E1 and 5E2, one of the mounting plates, that is, the right mounting plate 5E1 in the illustrated example, has a magnetic sensor 8 fixed in the vicinity of the lower end thereof.

  The magnetic sensor 8 is constituted by, for example, a digital type Hall element. In the “view style” shown in FIG. 2B, the magnetic sensor 8 is formed of the bearing member 5D in the hinge housing 5C as shown in FIG. By approaching (oppositely facing) the magnet 9 disposed on the upper surface (the magnet disposed on the right side in FIG. 4), the magnetic sensor 8 reacts and is turned on to detect the “view style”. It is possible. That is, the magnetic sensor 8 and the magnet 9 constitute a style detection unit, and an output signal (style detection signal) thereof becomes a high level / low level corresponding to the on / off of the magnetic sensor 8. In this case, the magnetic sensor 8 is “ON” in the “view style”, and the magnetic sensor 8 and the magnet 9 are separated from each other in the “forward rotation open style” shown in FIG. Since the magnetic sensor 8 is located on the opposite side (left side in FIG. 4) of the magnet 9, the magnetic sensor 8 is turned off. Hereinafter, the magnet 9 is referred to as a style detection magnet.

  In addition to the style detection magnet 9, a malfunction prevention magnet 10 is disposed on the upper surface of the bearing member 5D of the hinge housing 5C. The malfunction prevention magnet 10 is a magnet having a magnetic pole opposite to that of the style detection magnet 9. For example, the style detection magnet 9 is an “N pole” as a magnetic pole on the end side facing the magnetic sensor 8. If there is, the malfunction preventing magnet 10 is arranged to be “S pole”. Further, when the display housing 2 is rotated 180 ° from the inverted state, that is, when the “inverted open style” or “view style” is changed to the “forward open style”, the malfunction preventing magnet 10 is moved to the magnetic sensor. 8 is arranged on the opposite side of the style detecting magnet 9 so as to be in a positional relationship opposite to that of FIG.

  When the magnetic sensor 8 and the style detection magnet 9 face each other, the malfunction-preventing magnet 10 continues to be in the ON state, that is, the “inverted open style” or “view style” state continues. In this case, even if the mounting plate 5E1 of the metal bracket 5E is magnetized by the magnetic force from the style detection magnet 9 and is changed to the “forward rotation open style”, the magnetic sensor 8 is turned on by the weak magnetic field. This is provided to prevent a malfunction that remains. That is, since the Hall element generally has a characteristic of reacting to a magnetic force in one direction, a new magnet 10 having a magnetic pole opposite to the magnetic pole of the style detecting magnet 9 is provided for preventing malfunction. , When changing to the “forward open style”, even if the metal bracket 5E is magnetized, it is provided to prevent it from being affected by the non-reactive off state due to the opposite magnetism. is there.

FIG. 5 is a block diagram showing basic components of a folding / rotating (composite) mobile phone device with a camera.
The CPU 11 is a central processing unit that controls the overall operation of the mobile phone device in accordance with various programs in the storage unit 12. The storage unit 12 is a non-volatile memory (internal memory), and is constituted by, for example, a ROM (flash memory or the like), and has a program area and a data area, and the operation shown in FIG. A program for realizing the present embodiment is stored according to the procedure. The memory (for example, static RAM) 13 is an internal memory having a work area, and the memory card 14 is a detachable recording medium, and is composed of, for example, a smart media, an IC card, a memory stick, etc. Image data and the like are exchanged between the two.

  A communication data processing unit 15 and an audio interface 16 are connected to the CPU 11. When a radio wave received from the antenna 17 is detected and demodulated by the wireless unit 18 and converted into a digital signal, it is given to the communication data processing unit 15. The communication data processing unit 15 determines whether the call is a call, a mail is received, or is received via the Internet. If the call is a call or a mail is received, the CPU 11 reads a ringtone set in the sound source IC unit 19 and reads an amplifier (AMP). 20, a ringing tone is generated and output from the notification speaker 21, and the notification LED 23 is driven to light through the display control unit 22. Further, if the call is a telephone call, the CPU 11 receives the audio data from the communication data processing unit 15 via the audio interface 16 when the connection with the other party is established according to the on-hook operation (response operation). 24 is generated and output. The input sound from the microphone 25 is given to the wireless unit 18 via the audio interface 16 and the communication data processing unit 15, modulated, and then transmitted from the antenna 17.

  In addition to the key operation unit 3, the display unit 4, and the magnetic sensor 8, which are input / output peripheral devices, a camera imaging control unit 26 and a charging connector unit 27 are connected to the CPU 11. The CPU 11 determines whether the current style of the apparatus main body is “open style” or “view style” based on the detection signal from the magnetic sensor 8, and changes the data display direction according to the style. . The camera imaging unit 26 includes a photographing lens, a lens / mirror block such as a mirror, an imaging element such as a CCD image sensor, a driving system thereof, a distance measuring sensor, a light amount sensor, an analog processing circuit, a signal processing circuit, a compression / expansion. A circuit or the like is provided to adjust and control the optical zoom, and to control drive control during autofocus, shutter drive control, exposure, white balance, and the like. The charging connector unit 27 is connected to a charging stand, and a secondary battery is charged by a charging current from the charging stand.

  Next, the operation concept (display processing according to the style) of the mobile phone device in this embodiment will be described with reference to the flowchart shown in FIG. Here, each function described in this flowchart is stored in the form of a readable program code, and operations according to the program code are sequentially executed. In addition, the operation according to the above-described program code transmitted via the transmission medium can be sequentially executed. In other words, in addition to the recording medium, an operation peculiar to this embodiment can be executed by using a program / data supplied externally via a transmission medium.

FIG. 6 is a flowchart showing the operation of the mobile phone device that starts executing when the power is turned on.
First, the CPU 11 acquires a style detection signal from the magnetic sensor (Hall element) 8 and checks its on / off state (step S1). Here, if the magnetic sensor 8 and the style detection magnet 9 are in a mutually opposing relationship, the magnetic sensor 8 reacts and is turned on, and its output (style detection signal) is at a high level. It is determined that the “view style” is set based on the style detection signal from the magnetic sensor 8. In this case, after the display control flag (horizontal flag) is turned on (step S2), a standby image prepared in advance is read out and displayed on the display unit 4 as a horizontal standby screen (step S3).

  On the other hand, when the style of the apparatus main body is changed so that the position of the magnetic sensor 8 is separated from the style detecting magnet 9 and the magnetic sensor 8 and the malfunction preventing magnet 9 are opposed to each other, the magnetic sensor 8 is insensitive. Since the output (style detection signal) is at a low level, the CPU 11 determines that the “forward rotation style” is set based on the style detection signal from the magnetic sensor 8 (step S1). NO). In this case, after the horizontal flag is turned off (step S7), the standby image is read and displayed on the display unit 4 as a vertical standby screen (step S8).

  When the incoming call or mail reception is detected in the state where the standby screen is displayed in this manner (YES in step S4), in addition to notifying the incoming call, the incoming image prepared in advance is read out, and the above-described landscape flag In response to ON / OFF, the horizontal incoming screen / vertical incoming screen is displayed on the display unit 4 (step S5), and an incoming call response process corresponding to incoming / incoming phone calls is executed (step S6). When the key of the key operation unit 3 or the side key 6 is operated (YES in step S9), the horizontal screen / vertical screen is displayed and output according to whether the horizontal flag is on or off (step S9). S10) A process corresponding to the operation key is executed (step S11).

  Further, the CPU 11 monitors whether the style detection signal from the magnetic sensor (Hall element) 8 has changed (step S12), and when it detects that the output of the magnetic sensor (Hall element) 8 has changed, the CPU 11 turns off. It is determined whether the change is on or on from off (step S13). Now, when the output of the magnetic sensor (Hall element) 8 is changed from “forward rotation style” to “view style” by changing from OFF to ON, the horizontal flag is turned ON (step S14), The currently displayed screen is converted to landscape and redisplayed on the display unit 4 (step S15). Conversely, when the “view style” is changed to “forward rotation style” by changing the output of the magnetic sensor (Hall element) 8 from on to off (NO in step S13), the landscape flag is turned off. At the same time (step S16), the currently displayed screen is converted to the portrait orientation and redisplayed on the display unit 4 (step S17).

  As described above, in this embodiment, in addition to the magnetic sensor 8 and the style detecting magnet 9 in the vicinity of the hinge mechanism portion 5 that rotatably connects the main body housing 1 and the display housing 2, this style detecting magnet is used. In the “view style” state where the magnetic sensor 8 and the style detecting magnet 9 are close to each other, the magnetic sensor 8 reacts and is turned on. When the sensor 8 and the malfunction-preventing magnet 10 are returned to the “open style” in which they are close to each other, the magnetic sensor 8 is turned off in a non-reactive state due to the reverse magnetism of the malfunction-preventing magnet 10. Therefore, even if the magnetic sensor 8 is kept on (view style), the magnetic sensor 8 can be reliably turned off when the magnetic sensor 8 and the style detection magnet 9 are separated. In other words, when the magnetic sensor 8 is changed from the “view style” to the “open style”, the magnetic sensor 8 is in a non-reactive off state due to the reverse magnetism, so that it is possible to reliably prevent the magnetic sensor from malfunctioning. Is effective against malfunctions caused by external magnetic field effects.

  In this case, since the magnetic sensor 8 is attached to the metal bracket 5E of the hinge mechanism portion 5, even if the metal bracket 5E or the like is magnetized, it is possible to reliably suppress the adverse effect due to the weak magnetic field. That is, in order to prevent malfunction of the magnetic sensor 8, the bracket 5E of the hinge mechanism portion 5 does not need to be made of a non-magnetic material such as synthetic resin, and the strength of the portion can be maintained by being made of metal. It becomes.

  On the other hand, when the display section 4 having a different aspect ratio by changing from “open style” to “view style” or “view style” to “open style” is changed from a landscape screen to a portrait screen or from a portrait screen to a landscape screen. In addition, since the CPU 11 changes the data display direction based on the output from the magnetic sensor 8, the data can be displayed in a form suitable for a horizontally long screen and a vertically long screen. In this case, the magnetic sensor 8 can be reliably turned on / off according to the style change and is not affected by the external magnetic field, so that the data display direction is reliably changed according to the portrait screen or landscape screen. It becomes possible.

In the above-described embodiment, the case where the present invention is applied to a folding / rotating (composite) mobile phone device is illustrated, but the present invention is also applicable to the rotating mobile phone device shown in FIG.
As shown in FIGS. 7A to 7C, the main body of the rotary mobile phone device has two housings 101 and 102 and a lower housing (including a key operation unit 103). (Main body housing) 101 and an upper housing (display housing) 102 provided with a key operation unit 105 in addition to the display unit 104 are rotatably attached via a rotation support shaft 106 constituting a rotary hinge mechanism unit. ing. FIG. 7A shows a state in which the apparatus main body is closed, that is, a state in which the main body housing 101 and the display housing 102 are overlapped (closed style), and FIG. 7B shows the rotation support shaft 106 as a center. (C) is a state in which the apparatus main body is opened, that is, the main body case 101 and the display case 102 are linear. A state (open style) in which 101 is rotated by 180 ° is shown.

  In this case, the detection of the above-mentioned “closed style” and “open style” is performed by, for example, a magnetic sensor and a style detection magnet (not shown) provided in the vicinity of the rotation support shaft 106, and the main body housing 101 is rotated 180 degrees. The magnetic sensor is turned “ON” when it is changed to the open style by rotating. Also in this case, a malfunction prevention magnet (not shown) having a magnetic pole opposite to that of the style detection magnet is provided, and the magnetic sensor is turned off when the magnet is changed to the “closed style”.

  In the embodiment described above, the magnetic sensor 8 and the style detection magnet 9 are opposed to each other so that the magnetic sensor 8 is turned on when changing to the “view style” of FIG. However, conversely, in the “forward rotation style”, the magnetic sensor 8 and the style detection magnet 9 may face each other and the magnetic sensor 8 may be turned on. In other words, the magnetic sensor 8 is generally turned off in the “open style” because the frequency of use in the “forward open style” is high, but in addition to the style detection magnet 9, a malfunction prevention magnet. By providing 10, it is possible to turn on the magnetic sensor 8 in the “forward rotation open style”.

  Further, in the above-described embodiment, the magnetic sensor 8 is attached to the bracket 5E and provided on the display housing 2 side. On the contrary, the magnetic sensor 8 may be attached to the upper surface of the bearing member 5D of the hinge mechanism portion 5. Good. That is, contrary to the above-described embodiment, the same effect can be obtained by providing the magnetic sensor 8 on the main body casing 1 side and providing the style detection magnet 9 and the malfunction prevention magnet 10 on the display casing 2 side.

In the above-described embodiments, the Hall element is used as the magnetic sensor, but a magnetoresistive element (MR element) may be used, and the type of the magnetic sensor is not limited.
In addition, the apparatus main body is not limited to the upper casing and the lower casing, and may be configured by three types of casings. Further, the present invention is not limited to the mobile phone device, and can be similarly applied to a mobile terminal device such as a PDA.

  On the other hand, a recording medium (for example, a CD-ROM, a flexible disk, a RAM card, etc.) on which program codes for executing the above-described units are recorded may be provided to the computer. In other words, a recording medium having a computer readable program code, and a magnetic sensor and a magnet arranged in the vicinity of a hinge mechanism portion that rotatably connects a plurality of housings constituting the apparatus main body are close to each other. When the magnetic sensor reacts and is turned on, it is detected that the form of the apparatus main body has changed from the first style to the second style. When the magnetic sensor approaches another magnet having a magnetic pole opposite to that of the magnet by rotating the casing, the magnetic sensor is turned into a non-reactive off state by the reverse magnetism, so that the second A function for detecting a change from a style to a first style, and from the first style to the second style or from the second style to the first style. When a display unit with a different aspect ratio is changed from a portrait screen to a landscape screen or from a landscape screen to a portrait screen, data is generated based on the output from the magnetic sensor that is turned on / off according to this style change. It is also possible to provide a computer-readable recording medium that records a program for realizing the function of changing the display orientation of the computer.
