  The above object, other objects, features and advantages of the present invention will become more apparent from the following detailed description of embodiments with reference to the drawings.

  With reference to FIG. 1, the mobile terminal 10 of this embodiment includes an antenna 12. The modulated audio signal (high frequency signal) sent from the other party is captured by the antenna 12, demodulated by the radio circuit 14, and decoded by the signal processing circuit 16. The audio data decoded by the signal processing circuit 16 is converted into an analog audio signal by the AD / DA conversion circuit 20, and the converted audio signal is output from the speaker 24 via the amplifier 22. When an incoming call operation, that is, an operation of pressing an incoming call button formed on the operation panel 40 is performed, a call can be made.

  On the other hand, when a call operation for a call is performed by the operation panel 40, the CPU 18 transmits a call signal to the other mobile terminal (not shown) through the signal processing circuit 16, the radio circuit 14 and the antenna 12. On the other hand, when the other party performs an incoming call operation, a call can be made.

  The voice signal taken in by the microphone 26 after the call is ready is amplified by the amplifier 28 and converted into voice data that is a digital signal by the AD / DA conversion circuit 20. The converted audio data is subjected to coding processing by the signal processing circuit 16 and further subjected to modulation processing by the radio circuit 14. The modulated audio signal generated by the radio circuit 14 is transmitted from the antenna 12.

  When a call end operation is performed by the operation panel 40 during a call with the other party in this way, the CPU 18 controls the signal processing circuit 16 and the radio circuit 14 to call the other party. Send an end signal. After transmitting the call end signal, the CPU 18 ends the call process. Also, when the call end signal is received from the other party first, the CPU 18 ends the call process. Thus, the call function is realized.

  When a shooting operation, that is, an operation of pressing a shooting button formed on the operation panel 40 is performed, the CPU 18 activates the camera 34. The object scene image captured by the camera 34 is converted by the camera processing circuit 36 into moving image data that is a digital signal. The converted moving image data is given to the LCD driver 30 via the CPU 18, and the LCD driver 30 converts the given moving image data into a composite video signal conforming to the NTSC system. The converted composite video signal is applied to the LCD monitor 32. As a result, a real-time moving image (through image) of the object scene is displayed on the LCD monitor 32.

  According to FIG. 2, the mobile terminal 10 of this embodiment includes an upper housing 50, a lower housing 52, and a hinge mechanism 54. The upper housing 50 and the lower housing 52 are connected to each other by a hinge mechanism 54 and can be opened and closed. The lower casing 52 is provided with a microphone 26, an operation panel 40, and an input device 42.

As shown in FIGS. 3A and 3B, the input device 42 includes a line sensor unit 44, support members 46a and 46b, and dome switches 48a to 48c. The line sensor unit 44 has a line sensor 44a in which a linear detection region extending in the left-right direction is formed, and reads a fingerprint sliding on the line sensor 44a . The elastic support members 46a and 46b support the line sensor unit 44 at both ends in the left-right direction. The dome switches 48 a to 48 c are arranged in the left-right direction corresponding to the back side of the line sensor unit 44. Each of the dome switches 48 a to 48 c transitions between an on state and an off state in response to contact with the back surface of the line sensor unit 44.

  According to FIG. 4, when the power is turned on, the CPU 18 activates the fingerprint acquisition circuit 44b. Although the motion detection circuit 44c is activated when the power is turned on, the motion information provided from the motion detection circuit 44c during activation of the fingerprint detection circuit 44b is invalidated by the CPU 18.

  When the fingerprint slides up and down the line sensor 44a, the line sensor 44a gives each of the images read in the detection area to the fingerprint acquisition circuit 44b. The fingerprint acquisition circuit 44b synthesizes the given images, converts the synthesized image thus created into digital data, and the converted digital data is output to the CPU 18. The CPU 18 performs an authentication process on the output digital data. If the processing result of the authentication process is successful, the CPU 18 stops the fingerprint detection circuit 44b, receives motion information given from the motion detection circuit 44c, and accepts pressing information from the dome switches 48a to 48c. The pressing information output from the dome switches 48a to 48c will be described later.

  Here, the operation of moving the fingerprint by the line sensor 44a is defined as “scrolling operation”, and the operation of pressing the line sensor 44a is defined as “pressing operation”. The pressing operation includes a center pressing operation, a left pressing operation, and a right pressing operation. The left pressing operation is an operation of pressing the left side of the line sensor 44a, the center pressing operation is an operation of pressing the center of the line sensor 44a, and the right pressing operation is an operation of pressing the right side of the line sensor 44a. The scroll operation includes a right scroll operation, a left scroll operation, an up scroll operation, and a down scroll operation. The right scroll operation is an operation of sliding the fingerprint from the left to the right by the line sensor 44a, and the left scroll operation is an operation of sliding the fingerprint from the right to the left by the line sensor 44a. The operation of sliding the fingerprint from the top to the bottom, and the bottom scrolling operation, ie, the operation of sliding the fingerprint from the top to the bottom on the line sensor 44a.

  When the right scroll operation is performed, the motion detection circuit 44c detects the motion of the fingerprint slid from the left to the right by the line sensor 44a, and the fingerprint is shifted from the left to the right based on the motion information thus detected. A notice to that effect is given to the CPU 18. The CPU 18 determines whether or not the notification obtained in this way can be executed. If it can be executed, the CPU 18 performs processing according to this instruction. Note that when a left scroll operation, an up scroll operation, and a down scroll operation are performed, the same processing as described above is executed.

  On the other hand, when the center pressing operation is performed, the entire line sensor unit 44 sinks, and all of the dome switches 48 a to 48 c arranged on the back side of the line sensor unit 44 are pressed. Each of the dome switches 48a to 48c transitions from the off state to the on state, and outputs a digital signal “1”. As a result, the press information “111” is input to the CPU 18.

When the pressing information “111” is input, the CPU 18 determines that the center of the line sensor 44a has been pressed, determines whether or not the process according to this instruction is executable, and if so, executes the process according to this instruction. Do.

  When the finger is separated from the line sensor 44a, the line sensor unit 44 is pushed up by all the repulsive forces of the dome switches 48a to 48c, and the line sensor unit 44 is returned to the original position. Each of the dome switches 48a to 48c transitions from the on state to the off state, and outputs a digital signal “0”. When the pressing information “000” is input to the CPU 18, the CPU 18 determines that the finger is released from the line sensor 44 a.

  When the left pressing operation is performed, the left side of the line sensor unit 44 sinks by the left pressing operation, and the dome switch 48 a arranged on the left back side of the line sensor unit 44 is pressed. The dome switch 48a transitions from the off state to the on state, and outputs a digital signal “1”. As a result, the press information “100” is input to the CPU 18.

  When the pressing information “100” is input to the CPU 18, the CPU 18 determines that the left side of the line sensor 44 a has been pressed, determines whether or not the process according to this instruction can be executed, and follows this instruction if it can be executed. Process.

  When the finger is separated from the line sensor 44a, the line sensor unit 44 is pushed up by the repulsive force of the dome switch 48a, and the line sensor unit 44 is returned to the original position. The dome switch 48a transitions from the on state to the off state, and outputs a digital signal “0”. When the pressing information “000” is input to the CPU 18, the CPU 18 determines that the finger is released from the line sensor 44 a.

  Note that the right side of the line sensor unit 44 is not displaced by the elastic support member 46b, and the dome switches 48b and 48c are not pressed even when the input device 42 is left pressed.

  When the right pressing operation is performed, the same processing as described above is executed.

  In this manner, in the input processing device 42, in addition to the processing of the CPU 18 based on the motion information detected by the motion detection circuit 44c, the processing of the CPU 18 based on the finger pressing force and the pressing position is executed. As a result, an input device that is small and capable of inputting various instructions is realized.

  Processing according to instructions from the CPU 18 will be specifically described with reference to FIGS. 5 (A) to 5 (E) and FIGS. 6 (A) to 6 (H). When the standby screen (see FIG. 5A) is displayed on the LCD monitor 32, if the right scroll operation is performed, the main menu (see FIG. 5B) is displayed on the LCD monitor 32. When the cursor C is on the “basic setting” shown in FIG. 5B and the up scroll operation is performed, the cursor C transitions to the “camera” (see FIG. 5C), and the down scroll operation is performed. When it is performed, the transition is made to the “data folder” (see FIG. 5D). When the cursor C is on the “basic setting” shown in FIG. 5B and the right scroll operation is performed, the basic setting (FIG. 5E) is displayed on the LCD monitor 32, and the left scroll operation is performed. When done, the main menu (see FIG. 5B) is displayed on the LCD monitor 32.

When the right scroll operation is performed during the playback mode (see FIG. 6A), the fast-forward mode (see FIG. 6B) of the music function is executed, and when the center pressing operation is performed, the playback mode (see FIG. 6B) is performed. 6 (A)) is executed again. When the left scroll operation is performed during the playback mode (see FIG. 6A), the rewind mode (see FIG. 6C) of the music function is executed, and when the center pressing operation is performed, the playback mode ( 6A) is executed again. When the up scroll operation is performed during the playback mode (see FIG. 6A), a process of raising the volume by one step (see FIG. 6D) is performed among the music functions, and when the center pressing operation is performed, The playback mode (see FIG. 6A) is executed again. When a downward scroll operation is performed during the playback mode (see FIG. 6A), a process of lowering the volume by one step (see FIG. 6E) is performed in the music function, and when a center pressing operation is performed, The playback mode (see FIG. 6A) is executed again. When the right press operation is performed during the playback mode (see FIG. 6A), the forward scan mode (see FIG. 6F) of the music function is executed, and when the center pressing operation is performed, the playback mode ( 6A) is executed again. When the left pressing operation is performed during the playback mode (see FIG. 6A), the backward scanning mode (see FIG. 6G) of the music function is executed, and when the center pressing operation is performed, the playback mode ( 6A) is executed again. When the center push operation is performed during the playback mode (see FIG. 6A), the pause mode (see FIG. 6H) of the music function is executed, and when the center push operation is performed during the pause. The reproduction mode (see FIG. 6A) is executed again.

The control program of the flowchart related to the mobile terminal 10 is stored in the flash memory 38.

  According to FIG. 7, the process waits until power is turned on in step S1. When the power is turned on, in step S3, the process waits until digital data is input from the fingerprint acquisition circuit 44b. At this time, the fingerprint acquisition circuit 44b is activated, and the fingerprint acquisition circuit 44b creates a fingerprint image based on the detection result of the detection area of the line sensor 44a. When digital data is input from the input device 42, authentication processing is performed on the digital data in step S5. At this time, the approval data registered in advance in the flash memory 38 is read, and the digital data input from the input device 42 is authenticated based on the approval data.

  In step S7, it is determined whether or not the use of the mobile phone 10 should be permitted based on the result of the authentication process. If the result of the authentication process is unsuccessful, it is determined that use of this form telephone 10 cannot be permitted, and the process proceeds to step S9.

On the other hand, if the result of the authentication process is successful, it is determined that the use of the mobile phone is permitted, and the process proceeds to step S13. At this time, while the fingerprint acquisition circuit 44b is stopped, the movement information of the movement detection circuit 44c is received and the pressing information of the dome switches 48a to 48c is received.

  In step S9, a login error screen is displayed on the LCD monitor 32, and it is determined whether or not the power is turned off in step S11. If the determination result is NO, the process returns to step S3, and if the determination result is YES, this process ends.

  In step S13, it is determined whether or not motion information is given. If the determination result is NO, the process proceeds to step S21. If the determination result is YES, it is determined whether or not the process corresponding to the motion information is executable in step S17. If it can be executed, the state transition corresponding to the motion information is executed in step S19, and if it cannot be executed, the process returns to step S15.

  In step S21, it is determined whether or not pressing information has been input. If a determination result is NO, it will progress to step S15, and if a determination result is YES, it will be discriminate | determined by step S23 whether the process corresponding to pressing information is executable. If it can be executed, the process according to the pressed information is executed in step S25, and if it cannot be executed, the process returns to step S15.
