Description

  The present invention relates to a portable terminal device and a program capable of changing the form of the apparatus main body to a plurality of styles.

  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 in widespread use, the two casings constituting the telephone body can be changed into two styles of a folded closed state and an opened state.

By the way, in a mobile phone having a key lock function, it is possible to prevent an erroneous operation when not in use such as when carrying it. For example, if the asterisk key is continuously pressed for 2 seconds, the key lock is turned on (enabled). When the asterisk key is pressed again for 2 seconds from the key lock ON state, the key lock is released and the key lock can be set to the OFF state (invalid). Here, conventionally, it is possible to perform a key lock operation in a stowed state (case closed state) without taking out from a pocket or the like in a mobile phone such as a folding type, a flip type (rotating type), and a sliding type. A mobile phone with a key lock function is known (see Patent Document 1).

  However, in the above-described mobile phone with a key lock function, the key lock can be performed by operating the keys that can be operated with the casing closed in a predetermined order a predetermined number of times. However, since ON / OFF of the key lock is based on the key operation, there is a risk of forgetting the operation.

  On the other hand, mobile phones with television receivers or mobile phones with image playback function that can play back recorded TV programs have begun to be put to practical use. Furthermore, the phone main body is not limited to the style in which the two cases are closed and the style in which it is opened, but there are also known models that can be changed to three or more styles, such as a style suitable for watching TV programs. . In this case, for example, when the key lock function is OFF when no key operation is required, such as when watching a TV program for a long time, or conversely when dialing or creating an e-mail, etc. When the key lock function is in the ON state, it is necessary to perform a key lock setting / release operation each time. This is not limited to the increase in the number of functions and the number of styles of mobile phones, and there is a risk that problems similar to those described above may occur in various cases.

  An object of the present invention is to enable automatic control of the validity or invalidity of a key lock for each style in a portable terminal device capable of changing the form of the apparatus main body to a plurality of styles.

The present invention is a portable terminal device capable of changing the form of the apparatus main body to a plurality of styles in accordance with relative changes of a plurality of housings constituting the apparatus main body, the key input means including a plurality of keys, For each style of a plurality of styles, setting storage means for storing the key lock setting or unlock setting , detection means for detecting the style of the apparatus main body, and operation when the key lock setting operation is performed by the user The key operation on each key in the key input means is controlled to be invalid according to the control, and the key lock setting is controlled to be stored in the setting storage means in association with the style of the apparatus body at that time, while the user When the unlock setting operation is performed by the control, the key operation for each key in the key input means is controlled to be valid according to the operation. A setting control means for controlling so as to set store unlocking setting in the setting storage unit in association with the style of the apparatus main body at this time, when the style of the apparatus main body is changed, corresponding to the changed style Then, the contents stored in the setting storage means are read, and when the key lock setting is set and stored, the key operation on each key in the key input means is controlled to be invalid, while the unlock setting is stored in the setting. If it is, key control means for controlling the key operation of each key in the key input means as valid is provided .

According to the present invention, it is possible to automatically control whether the key lock is enabled or disabled according to the style after the change by simply changing the style without performing the key lock setting operation or the release operation. It can be greatly reduced.

Embodiments of the present invention will be described below with reference to FIGS.

The rail members 7a and 7b on the lower housing 2 side are shorter than the rail members 6a and 6b on the upper housing 1 side, and are at least the vertical width (length in the sliding direction) of the key operation unit 5. When set to "open style" by shortening, all of the key operation unit 5 appears. The slide mechanism is provided with a stopper (not shown) for restricting the slidable range and preventing the rail from being detached.

  Further, in order to be able to detect whether it is set to “close style” or “open style”, a magnet 8 is provided at a predetermined position on the lower surface of the upper housing 1, and the lower housing is also provided. A magnetic sensor 9 is provided at a predetermined position on the upper surface 2. That is, the magnet 8 and the magnetic sensor 9 constitute a style detection unit that detects the current style. As shown in FIG. 3, in the “open style”, the magnet 8 and the magnetic sensor 9 are opposed to each other. Although the detection signal of the sensor 9 becomes a high level, in the “closed style”, the detection signal of the magnetic sensor 9 becomes a low level as the magnet 8 and the magnetic sensor 9 are separated from each other. The style detection unit is not limited to magnetic means, and may detect, for example, “closed style” or “open style” by turning on / off the microswitch, or by other mechanical means or optical means. You may make it do (it is the same below).

FIG. 4 is a block diagram showing basic components of the mobile phone device.
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 configured by, for example, a ROM (flash memory or the like), and has a program area and a data area. In the program area, FIGS. A program for realizing the present embodiment is stored in accordance with the operation procedure shown in FIG. 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 input / output peripheral devices, the CPU 11 includes a key operation unit 4 on the upper housing 1 side, a key operation unit 5 on the lower housing 2 side, a display unit 3 on the upper housing 1 side, and a magnetic sensor 9. The camera imaging unit 26 and the charging connector unit 27 are connected. For example, the magnetic sensor 9 outputs a high level detection signal when the magnet 8 and the magnetic sensor 9 face each other in the “open style”, and when the magnet 8 and the magnetic sensor 9 are separated in the “close style”. The CPU 11 outputs a low level detection signal, and the CPU 11 determines whether it is set to “open style” or “close style” based on the detection signal from the magnetic sensor 9.

  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 (not shown), and a secondary battery in the mobile phone is charged by a charging current from the charging stand.

FIG. 5 is a diagram showing the configuration of the key lock control table 28 provided in the internal memory of the mobile phone device.
The key lock control table 28 stores and manages key control information indicating whether the key lock is valid or invalid corresponding to a plurality of styles “close style” and “open style” of the apparatus main body. A case where “lock ON” indicating the validity of the key lock is stored corresponding to “closed style” and “lock OFF” indicating the invalid key lock is stored corresponding to “open style” is illustrated. ing. The contents (key control information) of the key lock control table 28 are arbitrarily set in advance by the user. At that time, the key control information for each style is not limited to the input setting. For example, when arbitrary key control information is selected and set for each style, the setting method is arbitrary.

  Next, the operation concept of the mobile phone device in this embodiment will be described with reference to the flowcharts shown in FIGS. Here, each function described in these flowcharts 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, the program / data supplied externally via the transmission medium can be used to execute the operation specific to this embodiment.

FIG. 6 and FIG. 7 are flowcharts showing the operation of the mobile phone device that starts to be executed when the power is turned on.
First, when the power is turned on, the standby mode is set, and a preset wallpaper image is read and pasted and displayed (step S1), the CPU 11 acquires a detection signal of the magnetic sensor 9. The current style is determined (step S2). In this case, in the “open style”, the magnet 8 and the magnetic sensor 9 face each other so that the detection signal of the magnetic sensor 9 becomes a high level, and in the “closed style”, the magnet 8 and the magnetic sensor 9 are separated from each other. Since the detection signal 9 becomes a low level, the current style can be determined based on the detection signal from the magnetic sensor 9.

  If “close style” is set (YES in step S3), the key lock control table 28 is accessed to read the setting content corresponding to “close style”. In the example of FIG. "Lock ON" indicating the validity of is read (step S4). If “open style” is set (NO in step S3), the key lock control table 28 is accessed to read the setting contents corresponding to “open style”. In the example of FIG. “Lock OFF” indicating invalidity is read (step S5). Then, it is determined whether or not the setting content read from the key lock control table 28 is “lock ON” (step S6). If it is “lock ON”, it is set to a lock ON state for operating the key lock function (step S6). S7). Accordingly, in this lock ON state, all other keys are set to an operation invalid state except for some of the keys described above.

In such a key lock state, when an incoming signal is detected (step S8), an incoming call corresponding process is executed to notify that, and if it is a call, a call connection is made according to the response operation, and mail is sent. If it is reception, mail reception processing is performed (step S9).
Further, in the key lock state, in order to release the lock state, the lock key is operated by determining whether or not the determination key 1F on the upper housing 1 is pressed for a long time, for example, for 2 seconds or more. It is determined whether or not (step S10). Here, even if the enter key 1F is operated, if it is pressed for less than 2 seconds, it is recognized as an erroneous operation (NO in step 10), the process proceeds to step S16 to invalidate the operation, and again the magnetic sensor 9 detection signals are obtained to determine whether the current style has been changed. If the style is not changed, the process returns to the above-described incoming / outgoing determination step S8. However, if the style change is detected, the process returns to the above-described style discrimination processing step S2.

  If the enter key 1F is pressed for a long time and the key lock release is designated (YES in step S10), the key lock state is released in response to this, and all keys are returned to the valid state (step S10). S11). At this time, the CPU 11 again acquires the detection signal of the magnetic sensor 9 to determine the current style (step S12), and performs a process of rewriting the contents of the key lock control table 28 associated with the current style. (Steps S13 to S15). That is, if the style when the lock key (decision key) 1F is operated is “closed style” (YES in step S13), the key lock control table 28 is accessed and the setting content corresponding to “closed style” is set to “ If the style at the time of operating the lock key is “open style” (NO in step S13), the key lock control table 28 is accessed to set the setting contents corresponding to “open style”. It is rewritten to “lock OFF” (step S15). Thereafter, the process proceeds to step S17 and subsequent steps in FIG. On the other hand, also when it is determined as “lock OFF” in step S6 described above, the process proceeds to step S17 and subsequent steps in FIG.

  First, when the CPU 11 detects an incoming signal in a state where the key lock is released (YES in step S17), the CPU 11 executes the above incoming response process (step S18). Whether or not the key is operated is checked (step S19). If no key is operated, the presence or absence of the style change is checked (step S20). If the style is not changed, the process returns to the above-described incoming / outgoing determination step S17. However, if the style is changed, the process returns to step S2 in FIG. Is performed. When any key operation is performed in a state where the key lock is released (YES in step S19), it is determined whether or not the operation key is the enter key 1F on the upper housing 1 ( Step S21), if it is not the enter key 1F, or if the enter key 1F is not a long press operation (NO in step S22), after the process corresponding to the operation key is executed (step S23), whether there is an incoming call Return to the determination step S17.

  On the other hand, when the enter key F is pressed for a long time when the key lock is released, it is recognized that the lock key is operated (steps S21 and S22), and the key lock state is changed from the unlocked state. (Step S24) After that, as in the case described above, the detection signal of the magnetic sensor 9 is acquired again to determine the current style (step S25), and the key lock control associated with the current style is performed. Processing for rewriting the contents of the table 28 is performed (steps S26 to S28). That is, if the style when the lock key (decision key) 1D is operated is “closed style” (YES in step S26), the key lock control table 28 is accessed and the setting content corresponding to “closed style” is set to “ If it is “open style” (NO in step S26), the key lock control table 28 is accessed and the setting content corresponding to “open style” is rewritten to “lock ON” (step S27). Step S28). Thereafter, the process proceeds to step S8 and subsequent steps in FIG.

  As described above, in this embodiment, the CPU 11 acquires the detection signal of the magnetic sensor 9 in a state where the key control information indicating the validity or invalidity of the key lock is stored and managed in the key lock control table 28 for each style. In addition to determining the current style, whether the key lock is enabled or disabled is determined based on the key control information associated with this style, and if the key lock is disabled, the key is controlled to be operable. If the key lock is enabled, the key is controlled to be inoperable. Just change the style without performing the key lock setting operation or release operation. It is possible to automatically control whether the key lock is valid or invalid, and the burden on the user can be greatly reduced.

  In this case, key control information indicating whether key lock is enabled or disabled can be set arbitrarily for each style. For example, what style to carry and how to use it to view images. It is possible to make settings that match the individuality of the user and improve usability. Furthermore, when setting the validity or invalidity of the key lock arbitrarily for each style, the CPU 11 determines the current style and changes the contents of the key lock control table 28 corresponding to this style to the newly set contents. Thus, the contents set corresponding to the current style can be freely switched at any time from the key lock “valid” to “invalid” or “invalid” to “valid”.

  The CPU 11 determines whether the key lock is valid or invalid based on the key control information corresponding to the “open style” when the “close style” is changed to the “open style”. Only by pulling out the lower housing 2 with respect to the upper housing 1 without performing the key lock, the key lock can be validated or invalidated. Conversely, when changing from "Open Style" to "Closed Style", the key lock is enabled or disabled based on the key control information corresponding to "Closed Style". The key lock can be validated or invalidated simply by pushing the lower housing 2 into the upper housing 1 without performing the above. In addition, when the power is turned on or when the style is changed, whether key lock is enabled or disabled is determined based on the key control information corresponding to the changed style, so that special key operations are performed when the power is turned on and when the style is changed. The key lock can be validated or invalidated without any problem.

In the above-described embodiment, the case where the present invention is applied to a slide-type mobile phone device is illustrated. However, the present invention is not limited to the slide-type, and for example, a fold-type mobile phone device, a folding / rotating type (composite type) The present invention can be similarly applied to a mobile phone device and a rotary mobile phone device.
8A and 8B show a foldable mobile phone device, and FIGS. 9A to 9D show a foldable / rotary (composite) mobile phone device. (A)-(C) are the external views which showed the rotation type mobile telephone apparatus. As with the slide type described above, the folding type, folding / rotating type, and rotating type mobile phone devices are equipped with a key lock function in order to prevent erroneous operation such as carrying, and the key lock function is provided. When set to the ON state (valid state), except for the power ON / OFF key and the key to release the key lock, the processing corresponding to the operation key is executed regardless of which other keys are operated. An impossible state (operation invalid state) is set.

FIG. 8A is a front view showing a state in which the apparatus main body is closed, and FIG. 8B is a front view in a state in which the apparatus main body is opened.
The apparatus main body includes two housings 101 and 102, and an upper housing 101 including a display unit 103 and a lower housing 102 including a key operation unit 104 form a connecting unit (opening / closing unit) 105. The key lock function is turned on for each of the closed style shown in FIG. 8 (A) and the open style shown in FIG. 8 (B). Key control information indicating “valid” or “off” (invalid) is arbitrarily set in the key lock control table 28. A plurality of side keys SK are arranged on both sides of the lower housing 102. When the key lock is set, each side key SK is a key lock target.

  Although not shown in the drawings, the style detection unit in this foldable mobile phone device is attached to a connecting unit 106 that rotates as the device main body is opened and closed, and is magnetic, electrical, mechanical, and optical. The current style is detected by any means or a combination thereof. For example, if the micro switch provided in the vicinity of the connecting portion 106 is switched from “off” to “on” when the closed style is changed to the open style, the current style is changed based on the switch signal. If the switch signal output from the style detection unit is at a low level, the CPU 11 can determine that it is a closed style, and if the switch signal is at a high level, it is an open style. Note that, as a third style, a state in which the upper housing 101 is raised by about 90 ° to 120 ° with respect to the lower housing 102 may be a “view style” during image reproduction.

  FIG. 9 shows a folding / rotating type mobile phone device. The folding / rotating type mobile phone device includes an upper casing 101 having a display unit 103 and a lower part having a key operation unit 104. In addition to a foldable structure that allows the housing 102 to be opened and closed via a connecting portion (opening / closing portion) 105, it has a rotating structure that allows a part of the upper housing 101 to rotate 180 °. That is, the upper housing 101 is provided with a housing portion (base portion) 101A attached to the lower housing 102 via the connecting portion 106 so as to be openable and closable, and the base portion 101A via a rotation axis (vertical axis) 107. The display unit 103 is divided into a housing portion (display side portion) 101B that is rotatably attached, and is displayed via the rotation shaft 107 when the upper housing 101 and the lower housing 102 are opened. By rotating the side portion 101B by 180 °, the display unit 103 can be rotated in the reverse direction (back side). A plurality of side keys SK are arranged on both sides of the lower housing 102. When the key lock is set, each side key SK is a key lock target.

  9A shows a state in which the apparatus main body is closed, FIG. 9B shows a state in which the apparatus main body is opened, FIG. 9C shows a state in which the display unit 103 is rotated in the reverse direction, and FIG. FIG. 6 is a diagram illustrating a state in which an upper housing 101 is overlaid on a lower housing 102 while 103 is rotated in the reverse direction. Here, as in the case described above, the state of FIG. 9 (A) is the closed style, and the state of (B) is the open style, but the state of (D) is the third style, that is, during image reproduction. When referred to as “view style”, this folding / rotation type mobile phone device has three types of styles, and the close style and the open style are detected by the same style detector as described above. This style (view style) is detected by, for example, a micro switch (not shown) provided in the vicinity of the rotation shaft 107.

  In this case, if the micro switch is switched from “OFF” to “ON” by rotating the display side portion 101B of the upper casing 101 by 180 °, the current style is detected based on this switch signal. Is possible. The current style may be detected by any one of magnetic, electrical, mechanical, and optical means or a combination thereof. Further, the fourth style may be the state shown in FIG. 9C, that is, the state where the photographing lens faces the face of the user (the state where the subject is photographed as a subject).

FIG. 10 shows a rotary type mobile phone device. The device main body has two housings 201 and 202, and an upper housing 201 including a display unit 203 and a key operation unit 204, A lower casing 202 having a key operation unit 205 is a rotary apparatus main body that is rotatably attached via a rotary shaft (vertical axis) 206.
FIG. 10A shows a state in which the apparatus main body is closed, that is, a state in which the upper housing 201 and the lower housing 202 are overlapped (closed style), and FIG. (C) shows a state in which the apparatus main body is opened, that is, the upper casing 201 and the lower casing 202 are linear so that the upper casing 201 and the lower casing 202 are linear. Shows a state (open style) rotated 180 °.

  In this case, the detection of the above-described closed style and open style is performed by, for example, a micro switch (not shown) provided in the vicinity of the rotation shaft 206, and the micro is obtained by rotating the upper housing 20 by 180 °. If the switch is switched from “off” to “on”, the current style can be detected based on the switch signal. In this case as well, the current style may be detected by any one of magnetic, electrical, mechanical, optical means, or a combination thereof.

  The folding type, folding / rotating type (composite type), and rotating type mobile phone devices configured in this way also have the same effects as the slide type described above. In other words, each time the style is changed, these mobile phone devices automatically change the style without performing key lock setting or release operation, and automatically enable or disable key lock according to the changed style. This can be controlled, and the burden on the user can be greatly reduced. Further, the side keys SK can be arranged on both sides of the lower housing 102 by controlling the key lock according to the style.

In the above-described embodiment, all keys except for some keys are locked when the keys are locked. However, only keys that are arbitrarily selected and designated in advance may be targeted. In this case, for example, the key type to be locked can be stored and managed in the key lock control table 28 by style. Further, the key is not limited to a push button type key, and may be a key on a touch panel, and may further be a pointing device, a slide type switch, a rotary type switch, or the like.
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. That is, it is a recording medium having a computer-readable program code, and the key lock is enabled or disabled for each style in which the form of the apparatus main body is changed in accordance with the relative change of a plurality of casings constituting the apparatus main body. A function for storing and managing key control information, a function for determining whether key lock is valid or invalid based on the key control information associated with the style when a style of the apparatus main body is detected, and a key When it is determined that the lock is invalid, the key is controlled to be operable, and when the key lock is determined to be effective, the key is controlled to be inoperable. It is also possible to provide a computer-readable recording medium in which a program for causing the program to be recorded is recorded.
