Description

  The present invention relates to a portable terminal, and more particularly to a portable terminal that suitably prevents malfunction of a contact-type input unit.

  2. Description of the Related Art In recent years, mobile terminals, in particular mobile phones, have adopted housings configured in various types such as a slide type, a foldable type, a swivel type, and a reversible type.

  For example, a portable terminal having an opening / closing structure can be carried in a compact state by maintaining the closed state. Moreover, the portable terminal maintains an open state when in use, so that keypads such as operation keys are widely exposed, and various functions can be used with good operability.

A mobile phone configured in these various types has advantages and disadvantages for each type, and various techniques have been disclosed in the past to reduce these disadvantages (see, for example, Patent Document 1). .)

  On the other hand, various input devices that can perform an input operation of an operator easily and quickly are also known. In particular, in recent years, a technology that incorporates a touch sensor that can perform an input operation when an operator touches a portable terminal with a finger has come to be widely known. Since the touch sensor accepts input by contact, there is a high possibility of malfunction due to unintended contact. For this reason, it is conceivable that the mobile terminal is provided with a function of turning off the touch sensor at a predetermined timing.

  Here, when the mobile terminal having the open / close structure is operated to change between the open state and the closed state, the case of the mobile terminal is held by one or both hands of the operator, and is slid or rotated. Will be performed.

  With respect to the mobile terminal equipped with the touch sensor described above, a case where an operator's finger performing an operation of transitioning between the open state and the closed state is inadvertently touching the touch sensor is assumed. For this reason, there is a problem that during the operation of making a transition between the open state and the closed state, there is a very high possibility that a process accompanying the touch sensor touch will malfunction. Further, with the recent miniaturization of portable terminals, devices such as touch sensors, operation keys, and displays are densely packed, and the frequency of occurrence of unintentional touch sensors can be increased.

  The present invention has been made in consideration of such circumstances, and a portable terminal capable of preventing malfunction caused by unintentional contact with a contact-type input means that occurs during a transition operation between states of different housings. The purpose is to provide.

  In order to solve the above-described problem, a mobile terminal according to the present invention includes a housing capable of performing a transition operation between a first state and a second state different from the first state, and the surface of the housing A contact type input means for receiving an input of an instruction by detecting the start and end of contact, and start and end of a transition operation between the first state and the second state of the housing A detection means for detecting, and a control means for causing the contact-type input means to enter an off state in which no input is received when the start of the transition operation of the housing is detected by the detection means. To do.

  In addition, the mobile terminal according to the present invention is provided on a housing capable of transitioning between a first state and a second state different from the first state, and on the surface of the housing, and starts contact.

  The portable terminal according to the present invention can prevent malfunction caused by unintentional contact with the contact-type input means, which occurs during the transition operation between states with different housings.

  An embodiment of a portable terminal according to the present invention will be described with reference to the accompanying drawings. FIG. 1 is a diagram showing an external configuration of a slide type mobile phone 1 which is an example of a mobile terminal according to the present invention. FIG. 1A shows a configuration of an external appearance viewed from the front when the mobile phone 1 is extended and the second operation unit 21 is exposed (open state). FIG. 1B shows an external configuration viewed from the front when the cellular phone 1 is contracted and the main surface of the lower housing 12 and the back surface of the upper housing 13 overlap each other (closed state).

  In the mobile phone 1 shown in FIG. 1, the display 14 on the main surface of the upper housing 13 is always exposed. When the upper housing 13 is slid in the arrow X direction with respect to the lower housing 12 from the closed state in which the upper housing 13 illustrated in FIG. The second operation unit 21 on the lower housing 12 appears in the open state shown in FIG. The open state and the closed state correspond to a “first state” and a “second state”, or a “second state” and a “first state”, respectively.

  The display 14 occupies most of the area on the main surface of the upper housing 13. The display 14 can display e-mail content, a simple homepage, etc. in addition to the radio wave reception state and the remaining battery level. The display 14 is a display composed of, for example, an LCD (Liquid Crystal Display), an organic EL (ElectroLuminescence) display, or an inorganic EL display.

  A first operation unit 15 for performing a limited operation is arranged in an area below the display 14. The first operation unit 15 is provided with input means including a cross key 16 having up / down / left / right direction keys, a confirmation key 17, and a touch sensor 18.

  When the cross key 16 is operated in the up / down / left / right direction, the cursor or the like displayed on the display 14 can be moved in the up / down / left / right direction. In addition, when the confirmation key 17 is pressed, various process confirmation processes are executed.

  A predetermined number (for example, four) of touch sensors 18 are arranged, and are arranged so as to surround the periphery of the cross key 16. The touch sensor 18 functions as a contact-type input unit that receives an instruction input by detecting the start and end of contact together with the control unit (the control unit 41 in FIG. 2). Various methods such as a capacitance method, a resistive film method, an acoustic pulse method, an ultrasonic method, a surface acoustic wave method, an infrared light shielding method, and an electromagnetic induction method can be applied to the touch sensor 18.

  As shown in FIG. 1A, on the main surface of the lower housing 12, for example, a second operation unit 21 that is input by pressing is disposed. The second operation unit 21 is hidden behind the upper housing 13 in the closed state. The second operation unit 21 is provided with input means including operation keys 22. The operation keys 22 can input numbers from “0” to “9”, kana characters from “a” to “wa”, and alphabets from “A” to “Z”.

  In addition, the various input means comprised by the 1st operation part 15 and the 2nd operation part 21 are an example, Comprising: The key etc. to which the other function was allocated may further be arrange | positioned.

  A microphone (not shown) (microphone 25 in FIG. 2) and a receiver (receiver 26 in FIG. 2) (not shown) are provided at predetermined positions on the lower housing 12 or the upper housing 13, and a call function can be realized. The microphone collects the voice of the user during a call and converts it into an electrical signal. The receiver converts the electrical signal into audible sound. A battery pack (not shown) is inserted into the lower housing 12 on the back side. When the mobile phone 1 is turned on by a predetermined input operation, power is supplied from the battery pack to each circuit unit to start operation.

  The mobile phone 1 is provided with magnetic sensors 24a, 24b, 24c, and 24d (magnetic sensor 24) for detecting the open state and the closed state of the housings 12 and 13. The magnetic sensors 24 a and 24 b are arranged at predetermined positions on the upper housing 13. The magnetic sensors 24 c and 24 d are disposed at predetermined positions inside the lower housing 12. The magnetic sensor 24 functions as a detection unit that detects the start and end of the transition operation between the open state and the closed state of the housings 12 and 13.

  FIG. 2 is a diagram illustrating an internal configuration of the mobile phone 1 according to the present embodiment. A radio signal transmitted from a base station (not shown) is received by an antenna 31 and then input to a receiving circuit (RX) 33 via an antenna duplexer (DUP) 32. The receiving circuit 33 mixes the received radio signal with the local oscillation signal output from the frequency synthesizer (SYN) 34 and converts the frequency into an intermediate frequency signal (down-conversion). Then, the reception circuit 33 orthogonally demodulates the down-converted intermediate frequency signal and outputs a reception baseband signal. The frequency of the local oscillation signal generated from the frequency synthesizer 34 is instructed by a control signal SYC output from the control unit 41.

  The reception baseband signal from the reception circuit 33 is input to the CDMA signal processing unit 36. The CDMA signal processing unit 36 includes a RAKE receiver (not shown). In this RAKE receiver, a plurality of paths included in the received baseband signal are despread with each spreading code (that is, the same spreading code as that of the spread received signal). Then, the signals of the respective paths subjected to the despreading process are subjected to coherent Rake synthesis after the phase is adjusted. The data sequence after Rake combining is subjected to deinterleaving and channel decoding (error correction decoding), and then binary data determination is performed. Thereby, received packet data of a predetermined transmission format is obtained. This received packet data is input to the compression / decompression processor 37.

  The compression / decompression processing unit 37 is configured by a DSP (Digital Signal Processor) or the like, and the received packet data output from the CDMA signal processing unit 36 is separated for each medium by a demultiplexing unit (not shown). Each data is decrypted. For example, in the call mode, audio data corresponding to call voice included in the received packet data is decoded by a speech codec. Also, if the received packet data includes moving image data, such as the videophone mode, this moving image data is decoded by a video codec. Further, if the received packet data is a download content, the download content is decompressed, and then the decompressed download content is output to the control unit 41.

  The digital audio signal obtained by the decoding process is supplied to the PCM codec 38. The PCM codec 38 PCM-decodes the digital audio signal output from the compression / decompression processor 37 and outputs the analog audio data signal after PCM decoding to the reception amplifier 39. The analog audio signal is amplified by the reception amplifier 39 and then output from the receiver 26.

  The digital moving image signal decoded by the video codec by the compression / decompression processing unit 37 is input to the control unit 41. The control unit 41 displays a moving image based on the digital moving image signal output from the compression / decompression processing unit 37 on the display 14 via a video RAM (for example, a VRAM) (not shown).

  Further, when the received packet data is an electronic mail, the compression / decompression processing unit 37 supplies the electronic mail to the control unit 41. The control unit 41 stores the electronic mail supplied from the compression / decompression processing unit 37 in the storage unit 42. And the control part 41 reads this electronic mail memorize | stored in the memory | storage part 42 according to operation of the operation key 22 as an input part by a user, and displays the read electronic mail on the display 14. FIG.

  On the other hand, in the call mode, the voice signal (analog audio signal) of the speaker (user) input to the microphone 25 is amplified to an appropriate level by the transmission amplifier 40 and then PCM encoded by the PCM codec 38. The digital audio signal after the PCM encoding is input to the compression / decompression processing unit 37. Further, an electronic mail which is text data created by the control unit 41 is also input to the compression / decompression processing unit 37.

  The compression / decompression processor 37 compresses and encodes the digital audio signal output from the PCM codec 38 in a format corresponding to a predetermined transmission data rate. Thereby, audio data is generated. The compression / decompression processing unit 37 compresses and encodes the digital moving image signal output from the control unit 41 to generate moving image data. Then, the compression / decompression processing unit 37 multiplexes these audio data and moving image data by a demultiplexing unit (not shown) according to a predetermined transmission format and then packetizes them, and the packetized transmission packet data is transmitted to the CDMA signal processing unit 36. Output to. Note that the compression / decompression processing unit 37 also multiplexes the e-mail into the transmission packet data even when the e-mail is output from the control unit 41.

  The CDMA signal processing unit 36 performs spread spectrum processing on the transmission packet data output from the compression / decompression processing unit 37 using a spreading code assigned to the transmission channel, and transmits the output signal after the spread spectrum processing to the transmission circuit ( TX) 35. The transmission circuit 35 modulates the signal after the spread spectrum processing using a digital modulation method such as a QPSK (Quadrature Phase Shift Keying) method. The transmission circuit 35 combines the digitally modulated transmission signal with a local oscillation signal generated from the frequency synthesizer 34 and frequency-converts (up-converts) the signal into a radio signal. Then, the transmission circuit 35 amplifies the radio signal generated by this up-conversion with high frequency so that the transmission power level instructed by the control unit 41 is obtained. The radio signal amplified by the high frequency is supplied to the antenna 31 via the antenna duplexer 32 and transmitted from the antenna 31 to a base station (not shown). The mobile phone 1 is also provided with a clock circuit 45 that measures the current accurate time and a predetermined time.

  The control unit 41 includes a CPU (Central Processing Unit), a ROM (Read Only Memory), a RAM (Random Access Memory), and the like. The CPU executes various processes according to programs stored in the ROM or various application programs loaded from the storage unit 42 to the RAM, generates various control signals, and supplies them to the respective units, thereby supplying the cellular phone 1. Overall control. The RAM appropriately stores data necessary for the CPU to execute various processes. The control unit 41 also includes a video RAM, and temporarily stores information related to the video displayed on the display 14. The control unit 41 functions as a control unit in the present embodiment.

  The storage unit 42 includes, for example, a flash memory element that is an electrically rewritable and erasable nonvolatile memory, an HDD (Hard Disc Drive), and the like, and various application programs executed by the CPU of the control unit 41 and various types The data group is stored. The power supply circuit 44 generates a predetermined operating power supply voltage Vcc based on the output of the battery 43 and supplies it to each circuit unit.

  FIG. 3 is a diagram for explaining the transition operation from the closed state to the open state of the mobile phone 1 in the present embodiment. Note that the description of the transition operation from the open state to the closed state of the mobile phone 1 is the reverse of the transition operation from the closed state to the open state in FIG.

  As shown in FIG. 3, when the lower housing 12 and the upper housing 13 are slid to change from the closed state to the open state, the operator holds the finger on the upper housing 13 as shown in FIG. There is a high possibility of pressing against any position (in the figure, the area where the touch sensor 18 is disposed). After that, as shown in FIG. 3 (B), the operator slides the upper casing 13 in the direction of the arrow X, thereby changing the state of the mobile phone 1 to the open state shown in FIG. 3 (C). Let At this time, the operator's finger that slides the upper housing 13 is very likely to contact the touch sensor 18.

  The mobile phone 1 according to the present embodiment can suitably prevent a malfunction caused by an unintended contact with the touch sensor 18 during the transition operation between the open state and the closed state of the casings 12 and 13. it can.

  In the input process during the case transition operation described below, the mobile phone 1 detects the end of the transition operation after the start of the transition operation of the cases 12 and 13 until the end of the transition operation is detected. By turning off the power supply, it is possible to prevent an erroneous operation due to an unintended contact with the touch sensor 18.

  Here, the cellular phone 1 detects the detection levels of the magnetic sensors 24a and 24b provided in the upper casing 13 by the magnetic sensors 24c and 24d of the lower casing 12 shown in FIG. The end and the current state (open state and closed state) of the casings 12 and 13 are detected.

  The start of the transition operation from the closed state to the open state in the present embodiment corresponds to the time when the detection signal of the magnetic sensor 24a detected by the magnetic sensor 24d has shifted to a predetermined level or less. The end of the transition operation from the closed state to the open state corresponds to the time when the detection signal of the magnetic sensor 24b detected by the magnetic sensor 24c has shifted to a predetermined level or higher. The start of the transition operation from the open state to the closed state corresponds to the time when the detection signal of the magnetic sensor 24b detected by the magnetic sensor 24c shifts to a predetermined level or less. The end of the transition operation from the open state to the closed state corresponds to the time when the detection signal of the magnetic sensor 24a detected by the magnetic sensor 24d has shifted to a predetermined level or higher. The arrangement of the magnetic sensors 24a to 24d is not limited to this. Also, the number is not limited. Further, it may be determined mechanically whether the state is (A) or (C) in FIG.

  FIG. 4 is a flowchart illustrating an input process during a case transition operation executed by the control unit 41 of the mobile phone 1 according to the present embodiment. The input processing during the case transition operation is performed after the mobile phone 1 receives an instruction to turn on the power by a predetermined input operation or after the operation lock of the first operation unit 15 and the second operation unit 21 is released. (It may be applied to unlocking some operation units, or may be applied to unlocking the jog dial 17 and unlocking the touch sensor 18; the same applies hereinafter). It starts when the execution of is started. In addition, the touch sensor operation is not input simply by touching, but a predetermined time elapses from the contact (long press operation) or the end of contact is detected before the predetermined time elapses from the contact (short press operation) ).

  In step S <b> 1, the control unit 41 turns on the touch sensor 18. The touch sensor 18 can accept an input operation by detecting the start of contact (hereinafter referred to as touch) and the end of contact (hereinafter referred to as release).

  In step S2, the control unit 41 determines whether or not the input process has been completed. The input process is ended when the mobile phone 1 receives an instruction to turn off the power by a predetermined input operation or when the operation lock of the first operation unit 15 or the second operation unit 21 is set. If the control unit 41 determines that the input process has ended, the control unit 41 ends the input process during the case transition operation.

  On the other hand, when it is determined that the input process has not ended, the control unit 41 determines whether or not the occurrence of a predetermined event is detected in step S3. The predetermined events correspond to start and end events of transition operations of the casings 12 and 13 and touch and release events of the touch sensor 18. In the present embodiment, the description of the case where another event process (for example, pressing of the operation key 22 or incoming call) occurs is omitted. When it is determined that the predetermined event has not been detected, the control unit 41 returns to the input process end determination step S2.

  When the controller 41 detects the occurrence of the start event of the transition operation of the casings 12 and 13 in the event occurrence determination step S3, the controller 41 sets the casing operation flag to ON in step S4. In step S <b> 5, the control unit 41 turns off the power of the touch sensor 18 and turns it off so as not to accept the input of the touch sensor 18. Here, when the touch sensor 18 is turned off, the control unit 41 does not detect the touch and release of the touch sensor 18. For this reason, the cellular phone 1 does not malfunction the process assigned to the touch sensor 18 even if an unintended contact with the touch sensor 18 occurs during the transition operation of the housings 12 and 13.

  In step S6, the control unit 41 turns off the touch flag. This touch flag is normally set to ON in flag ON step S9 after detecting a touch event of the touch sensor 18 in event occurrence determination step S3. The control unit 41 discards the touch event of the touch sensor 18 that has already been generated and detected by turning off the touch flag with the start of the transition operation of the housings 12 and 13. In addition, the control part 41 maintains an OFF state as it is, when a touch flag is OFF in step S6. The control unit 41 returns to the input process end determination step S2 and repeats the subsequent processes.

  Next, when the control unit 41 detects an end event of the transition operation of the casings 12 and 13 in the event occurrence determination step S3, the control unit 41 turns off the casing operation flag in step S7. In step S <b> 8, the control unit 41 turns on the power of the touch sensor 18 and turns it on to accept the input of the touch sensor 18. In accordance with the detection of the start of the transition operation of the casings 12 and 13, this process turns on the touch sensor 18 that has been turned off in the touch sensor OFF step S5 to return it to a state in which an input operation can be accepted. It is processing. The control unit 41 returns to the input process end determination step S2 and repeats the subsequent processes.

  On the other hand, when the control unit 41 detects a touch event of the touch sensor 18 in the event occurrence determination step S3, the control unit 41 sets a touch flag to ON in step S9. The control unit 41 returns to the input process end determination step S2 and repeats the subsequent processes.

  In addition, when the occurrence of the release event of the touch sensor 18 is detected in the event occurrence determination step S3, the control unit 41 determines whether or not the touch flag is set on in step S10. When it is determined that the touch flag is off, the control unit 41 discards the release event in step S11. This is because the corresponding touch event has not occurred. When release is detected even though the touch flag is off, the touch sensor 18 remains touched before the start of the transition operation of the housings 12 and 13 and during the transition operation (the touch sensor 18 is in the off state). The case where the touch sensor 18 is released after the transition operation of the casings 12 and 13 is finished (the touch sensor 18 is in the on state) corresponds to this case.

  When it is determined that the touch flag is set on, the control unit 41 turns off the touch flag in step S12. In step S13, a predetermined process associated with the occurrence of the release event of the touch sensor 18 is detected. In other words, the control unit 41 executes a predetermined process based on an instruction that has received an input from the touch sensor 18. As described above, the control unit 41 is configured to execute a predetermined process assigned to the touch sensor 18 when a release corresponding to the detected touch is detected. The touch sensor 18 can accept different input operations depending on the time from touch to release (contact time). The touch sensor 18 is not limited to the above-described operation, and may be configured to execute a predetermined process when a touch is detected. The control unit 41 returns to the input process end determination step S2 and repeats the subsequent processes.

  In the input processing during the case transition operation, the touch sensor 18 is turned off from the start to the end of the transition operation of the cases 12 and 13. For this reason, since the touch and release events of the touch sensor 18 do not occur from the start to the end of the transition operation of the housings 12 and 13, it is preferable to prevent the occurrence of malfunction due to the transition operation of the housings 12 and 13. be able to.

  In addition, 1. 1. Touch event of touch sensor 18; 2. Transition operation start event of the casings 12 and 13; 3. Transition operation end event of the casings 12 and 13; When events occur in the order of release events of the touch sensor 18, 2. In the flag OFF step S6 after the occurrence of the transition operation start event of the casings 12 and 13, the touch flag is set to OFF. For this reason, even if an unintended touch sensor 18 touches before the transition operation of the casings 12 and 13 starts, 4. In the flag ON determination step S10 after the release event of the touch sensor 18 is determined, it is determined that the touch flag is OFF, the detection of release is discarded, and no malfunction occurs.

  Furthermore, since the touch sensor 18 is turned off during the transition operation of the housings 12 and 13, it is effective for power saving.

  Next, input processing at the time of another case transition operation executed by the mobile phone 1 in the present embodiment will be described.

  In the input processing at the time of another case transition operation described below, the mobile phone 1 detects the touch sensor after detecting the start of the transition operation of the cases 12 and 13 until the end of the transition operation is detected. When 18 touch or release events occur, the instruction received by the touch sensor 18 is ignored by discarding the event. For this reason, the mobile phone 1 can prevent an erroneous operation due to an unintended contact with the touch sensor 18. The details of the input processing during other case transition operations will be described below.

  FIG. 5 is a flowchart for explaining an input process during another case transition operation executed by the control unit 41 of the mobile phone 1 according to the present embodiment. The other input processing during the case transition operation is performed after the mobile phone 1 receives an instruction to turn on the power by a predetermined input operation, or after the operation lock of the first operation unit 15 or the second operation unit 21. Is started when the input process is started.

  The processing from the touch sensor power ON step S21 to the event occurrence determination step S23 is substantially the same as the processing from the touch sensor power ON step S1 to the event occurrence determination step S3 in the input processing at the time of the housing transition operation in FIG. Is omitted.

  When the control unit 41 detects the occurrence of the start event of the transition operation of the casings 12 and 13 in the event occurrence determination step S23, the control unit 41 sets the casing operation flag to ON in step S24. In step S25, the control unit 41 sets the touch flag to OFF. The control unit 41 discards the touch event of the touch sensor 18 that has already occurred by turning off the touch flag with the start of the transition operation of the housings 12 and 13. In addition, the control part 41 maintains an OFF state as it is, when a touch flag is OFF by step S25. The control unit 41 returns to the input process end determination step S22 and repeats the subsequent processes.

  Next, when the control unit 41 detects an end event of the transition operation of the housings 12 and 13 in the event occurrence determination step S23, the control unit 41 turns off the housing operation flag in step S26. The control unit 41 returns to the input process end determination step S22 and repeats the subsequent processes.

  On the other hand, when the control unit 41 detects a touch of the touch sensor 18 in the event occurrence determination step S23, in step S27, the control unit 41 determines whether or not the housing operation flag is set to ON. When it is determined that the case operation flag is off, the control unit 41 sets the touch flag on in step S28. The control unit 41 returns to the input process end determination step S22 and repeats the subsequent processes.

  On the other hand, when it is determined that the case operation flag is set to ON, the control unit 41 discards the touch event in step S29. This is because the touch sensor 18 generated in spite of the transition operation of the housings 12 and 13 being performed, the generated touch event can be regarded as an unintended touch.

  In addition, when the occurrence of the release event of the touch sensor 18 is detected in the event occurrence determination step S23, the control unit 41 determines whether or not the housing operation flag is set on in step S30. When it is determined that the case operation flag is set to ON, the control unit 41 discards the release event in step S29. This is because the release of the touch sensor 18 that occurred in spite of the transition operation of the housings 12 and 13 being performed can be regarded as a release corresponding to an unintended touch.

  On the other hand, when it is determined that the case operation flag is off, the control unit 41 determines whether or not the touch flag is set on in step S31. If the control unit 41 determines that the touch flag is off, the control unit 41 discards the release event in step S29. This is because the corresponding touch event has not occurred.

  If release is detected even though the touch flag is off, the touch sensor 18 remains touched before the transition operation of the housings 12 and 13 starts and during the transition operation (the touch flag is off). For example, the touch sensor 18 is released after the transition operation of the bodies 12 and 13 is completed.

  If the control unit 41 determines in step S31 that the touch flag is set on, the control unit 41 turns off the touch flag in step S32. In step S33, a predetermined process associated with the detection of the release of the touch sensor 18 is executed. In other words, the control unit 41 executes a predetermined process based on an instruction that has received an input from the touch sensor 18. The control unit 41 returns to the input process end determination step S22 and repeats the subsequent processes.

  In the input processing during the other case transition operation, touch and release events of the touch sensor 18 that occur between the start and end of the transition operation of the cases 12 and 13 are discarded. For this reason, the execution instruction of the predetermined process accompanying the detection of the release of the touch sensor 18 can be ignored, and the occurrence of a malfunction due to the transition operation of the housings 12 and 13 can be suitably prevented.

  In addition, 1. 1. Touch event of touch sensor 18; 2. Transition operation start event of the casings 12 and 13; 3. Release event of touch sensor 18; 1. When events occur in the order of transition operation end events of the casings 12 and 13; 1. Touch event of touch sensor 18; 2. Transition operation start event of the casings 12 and 13; 3. Transition operation end event of the casings 12 and 13; When events occur in the order of release events of the touch sensor 18, the control unit 41 performs 2. The touch flag is turned off in flag OFF step S25 after the transition operation start event of the casings 12 and 13 occurs. That is, the control unit 41 discards the touch event detection when the transition operation of the housings 12 and 13 starts. Therefore, even if an unintended touch sensor 18 touches before the transition operation of the housings 12 and 13 occurs, 4. In the flag ON determination step S31 after the release event of the touch sensor 18, it is determined that the touch flag is OFF, and the detection of release is discarded, so that no malfunction occurs.

  According to the cellular phone 1, the touch sensor 18 is turned off or detected after the start of the transition operation of the casings 12 and 13 until the end of the transition operation is detected. By ignoring the input of the instruction accompanying the 18 touch or release event, it is possible to suitably prevent malfunction due to unintended contact with the touch sensor 18 during the transition operation of the housings 12 and 13.

  In the mobile phone 1 according to the present embodiment, an example in which a slide-type housing is applied as a housing that can perform a transition operation between the first state and the second state has been described. A mobile phone provided with another casing capable of configuring the above can be applied to the present invention. Examples of applicable cases are a so-called folding type that is hinged, a swivel type that can also rotate around a rotation axis perpendicular to the rotation axis of the hinge, and a reversible that can rotate about 360 degrees around the rotation axis of the hinge. It may be of a type.

  In addition, the arrangement of the contact type input means such as the touch sensor 18 is not limited to the arrangement shown in FIG. It only has to be done. Furthermore, the arrangement of the touch sensor 18 is not limited to the main surface of the upper casing 13, and may be on the lower casing 12 or the side surfaces of the casings 12 and 13.

  Furthermore, although the example which applied the magnetic sensor 24 as a detection means to detect the start and completion | finish of a housing | casing transition operation was demonstrated, you may replace with other means, such as an optical sensor.

  The present invention includes a PDA (Personal Digital Assistant), a personal computer, a portable game machine, a portable music player, a portable video player, other cases capable of transition operation, and a contact input means in addition to a cellular phone. It can also be applied to a mobile terminal equipped.

  Furthermore, the series of processes described in the embodiments of the present invention can be executed by software, but can also be executed by hardware.

  Furthermore, in the present embodiment, the steps of the flowchart show an example of processing that is performed in time series according to the described order. However, even if they are not necessarily processed in time series, they are executed in parallel or individually. It also includes processing.
