  An in-vehicle audio device that is a preferred embodiment of an electronic device according to the present invention will be described below with reference to the accompanying drawings.

  First, a schematic configuration of the in-vehicle audio device according to the present embodiment will be described. FIG. 1 is a schematic configuration diagram showing a schematic configuration of the in-vehicle audio device according to the present embodiment, and FIG. 2 is an overview diagram of the in-vehicle audio device.

  As shown in FIG. 1, the in-vehicle audio apparatus 1 includes a panel display 10, a main unit 20, a CD drive 30, and a DVD (Digital Versatile Disk) drive 40. This in-vehicle audio apparatus 1 reads and plays music information from a CD medium inserted into the CD drive 30 or a DVD medium inserted into the DVD drive 40.

  The panel display 10 includes a switch 11, a touch panel 12, a liquid crystal display 13, a tilt mechanism 14, and an open switch 15, and is rotated by the tilt mechanism 14. The main unit 20 includes an input processing unit 21, a display processing unit 22, a main control unit 24, a mechanism control unit 25, and a drive management unit 26.

  The input processing unit 21 receives inputs from the switch 11 and the touch panel and transmits them to the main control unit 24. Further, the display processing unit 22 causes the liquid crystal display 13 to display an image instructed by the main control unit 24. Further, the drive management unit 26 acquires information about the CD drive 30 and the DVD drive 40 and transmits it to the main control unit 24, and the mechanism control unit 25 receives the control from the main control unit 24, and receives the CD drive 30 and DVD. The physical operation of the drive 40 and the tilt mechanism 14 is controlled. Here, the physical operation in the tilt mechanism 14 is rotation of the panel display 10, and the physical operation in the CD drive 30 and the DVD drive 40 is an ejection operation of each medium.

  The main control unit 24 is a control unit that controls the in-vehicle audio apparatus 1 as a whole, and determines control contents and display contents based on inputs from the switch 11 and the touch panel 12 and the states of the CD drive 30 and the DVD drive 40. .

  Next, an overview of the in-vehicle audio device 1 and the rotation of the panel display 10 will be described with reference to FIG. In FIG. 2A, the in-vehicle audio device 1 has a panel display 10 disposed on the front surface of the main unit 20. The panel display 10 has a liquid crystal display 13 and a touch panel 12 superimposed on the center thereof, and a plurality of switches 11 and open switches 15 arranged on the periphery.

  The panel display 10 is rotated by a tilt mechanism 14 (not shown), and its position can be changed as shown in FIG. In the state shown in FIG. 2B, the CD drive 30 and the DVD drive 40 are exposed, and the medium can be taken in and out. That is, the user inserts and ejects CD media and DVD media in the state shown in FIG. 2B, and when it is not necessary to put in and out the media, the user can use the device in the state shown in FIG. The entire space is reduced. Here, the state shown in FIG. 2A is referred to as a panel closed state, and the state shown in FIG. 2B is referred to as a panel open state.

  In the conventional in-vehicle audio apparatus, physical operations such as the rotation of the panel display 10 and the ejection of the CD media and the DVD media are realized by operating the switch 11. However, as shown in FIG. 2, in order to enlarge the liquid crystal display 13, the number of switches 11 is limited. Therefore, in order to perform a desired operation, a plurality of switches are used in combination or pressed. It was necessary to change.

  The in-vehicle audio apparatus 1 according to the present embodiment can execute various operations including physical operations by designating icons displayed on the liquid crystal display 13. Specifically, when a predetermined switch (menu button) is designated from among the switches 11, the icon setting unit 24a in the main control unit 24 changes the states of the panel display 10, the CD drive 30, and the DVD drive 40. The acquired icon is displayed on the liquid crystal display 13 based on the acquired state. If the touch panel 12 detects designation of the displayed icon, an operation corresponding to the icon designated by the main control unit is executed.

  The processing operation in the in-vehicle audio device 1 will be further described with reference to FIG. FIG. 3 is a flowchart for explaining the processing operation in the in-vehicle audio apparatus 1. As shown in the figure, first, when a menu button which is one of the switches 11 is pressed (step S101), the drive management unit 26 acquires the states of the CD drive 30 and the DVD drive 40, and the main control. The unit 24 acquires the state of the panel display 10 (step S102).

  Subsequently, the icon setting unit 24a sets an icon to be displayed based on the drive state and the panel display state acquired in step S102 (step S103), and displays the icon on the liquid crystal display 13.

  Thereafter, an operation on the touch panel 12 is accepted (step S104), a control operation corresponding to the icon designated on the touch panel is executed (step S105), and the process is terminated.

  Next, a specific example of a display screen on the liquid crystal display 13 will be described. FIG. 4 is an explanatory diagram illustrating a display example of the liquid crystal display. As shown in the figure, the liquid crystal display 13 displays icons 51 to 55. The icon 51 is an icon corresponding to the discharge of the CD media, and the icon 52 is an icon corresponding to the discharge of the DVD media. The icon 53 is an icon that rotates the panel display 10 to make the panel open, and the icon 54 is an icon that rotates the panel display 10 to make the panel closed.

  Further, the icon 55 is an icon for adjusting the inclination of the panel display 10 to an arbitrary angle between the panel open state and the panel closed state. The icons 51 to 54 detect contact with the icon and execute a control operation, while the icon 55 accepts designation of an inclination amount in addition to execution of control. That is, the icon 55 functions as a virtual input unit that accepts an analog input.

  The icon 51 is a display indicating the state of the CD drive 30, and the icon 52 is a display indicating the state of the DVD drive 40. Specifically, the icon 51 indicates that a CD is being played, and the icon 52 indicates that no media is inserted in the DVD drive. Thus, by associating the icon image with the state of the drive, it is possible to check whether the medium is inserted and the reading state of the medium even in the panel closed state.

  Further, in FIG. 4, the icons 51, 53, and 55 are displayed brighter than the icons 52 and 54. This has an effect of highlighting an icon corresponding to a process that can be executed in the current state. That is, in the state shown in FIG. 4, since the DVD medium is not inserted, the icon 52 corresponding to the discharge of the DVD medium is darkly displayed. Similarly, since FIG. 4 shows the panel closed state, the icon 54 corresponding to the panel close is also displayed darkly.

  Needless to say, icons that do not need to be executed are not displayed darkly in this way, but only executable icons may be selectively displayed without displaying them.

  The icon setting process (step S103 in FIG. 3) to be displayed will be further described. FIG. 5 is a flowchart for explaining the processing operation for selecting the display content of the icon. As shown in the figure, the icon setting unit 24a first checks the state of the CD drive 30 (step S201).

  If a medium is inserted (set) in the CD drive 30 (step S202, Yes), the icon setting unit 24a determines whether the medium is being read (step S203), and the medium is being read. If present (step S203, Yes), an icon indicating that the medium is being used is selected (step S205). On the other hand, if the medium is not being read (step S203, No), the icon setting unit 24a selects an icon indicating the presence of the medium (step S204). If no media is inserted (set) in the CD drive 30 (step S202, No), the icon setting unit 24a selects an icon indicating that there is no media (step S206).

  Subsequently, the icon setting unit 24s checks the state of the DVD drive 30 (step S207). If a medium is inserted (set) in the DVD drive 40 (step S208, Yes), the icon setting unit 24a determines whether the medium is being read (step S209), and the medium is being read. If present (step S209, Yes), an icon indicating that the medium is being used is selected (step S211). On the other hand, if the medium is not being read (No at Step S209), the icon setting unit 24a selects an icon indicating the presence of the medium (Step S210). If no media is inserted (set) in the DVD drive 30 (No at Step S208), the icon setting unit 24a selects an icon indicating that there is no media (Step S212).

  Thereafter, the icon setting unit 24a selects an icon indicating the tilt state (tilt state) of the panel display 10 (step S213), determines the arrangement of each selected icon (step S214), and ends the process.

  In this way, by acquiring the current drive and panel display status and displaying the physical processing operations that can be executed as icons, the physical operations can also be operated with icons. And can be executed with a small number of operations.

  For example, in a conventional in-vehicle audio device, when exchanging media, it is necessary to display an audio operation screen to check the operation state of the drive, to open the panel display, and to press a media eject button. On the other hand, in the in-vehicle audio apparatus 1 according to the present embodiment, the operation state of the drive can be confirmed by pressing a menu button, an icon can be displayed, and the medium can be discharged by selecting the icon.

  Further, in the conventional in-vehicle audio device, whether the touch panel is in an open state, a closed state, or a tilt is set is distinguished depending on the length of time for which a predetermined button is pressed. In the in-vehicle audio apparatus 1 in FIG. 1, it is possible to easily perform an operation by creating a dedicated icon for each.

  In this way, the physical functions can also be controlled by icons, so that the number of physical switches can be reduced without deteriorating operability, and the space allocated for operations can be reduced. Visibility can be improved by increasing the area.

  Note that the in-vehicle audio apparatus 1 includes an open switch 15 for opening the panel so that the media can be ejected even when a failure occurs in the touch panel or the main unit 20. However, since the normal operation is performed by an icon, the open switch 15 can be specialized for emergency use and can be realized by a small switch.

  By the way, when the operation to change the tilt of the panel display is realized with icons, if the operation starts when a finger touches the touch panel, the position of the finger on the touch panel changes due to the rotation of the panel display, which may cause malfunction. Become.

  Therefore, when operating the touch panel, it is desirable to start the operation after the finger or the like has moved away from the touch panel. In this in-vehicle audio apparatus 1, first, a position designation on the touch panel due to a finger contact is detected, then a position designation release due to the finger being removed is detected, and an operation is started after a predetermined time has elapsed since the position designation was released. It is said.

  FIG. 6 is a flowchart for explaining the processing operation when the touch panel is operated (step S104 in FIG. 3). As shown in the figure, when a finger or the like touches the touch panel 12, the input processing unit 21 first acquires the position information (step S301), and the main control unit 24 designates an icon designated based on the position information. Is detected (step S302).

  Thereafter, the main control unit 24 waits for cancellation of the position designation (step S303). If the finger is released from the touch panel 12 and the position designation is released (step S303, Yes), the main control unit 24 determines whether or not the designated icon is an analog icon (step S304).

  When the specified icon is an icon that specifies an analog amount such as a panel tilt (step S304, Yes), the main control unit 24 calculates a control amount based on the position information. For example, if the specified icon is an icon 55 that specifies the inclination of the panel display 10, the inclination amount of the panel display 10 is calculated from the position information.

  After the calculation of the control amount (step S306) or when the designated icon is not an analog icon (No in step S304), the main control unit 24 waits for a predetermined time (step S305) and then executes the control operation. Move on.

  In this way, by confirming that the finger has been removed from the touch panel 12 and executing the control operation after a predetermined time has elapsed, it is possible to accurately detect the designation of the icon and prevent malfunction.

  As described above, in this embodiment, the states of the panel display 10, the CD drive 30, and the DVD drive 40 are acquired, and the physical processing operations that can be executed are displayed as icons. Since a physical operation can be executed, the operation can be simplified and executed with a small number of operations.

  Therefore, the number of physical switches can be reduced without deteriorating the operability, the display area can be increased, and the visibility can be improved. Further, when the icon is specified, the control operation is executed after a predetermined time has elapsed after the finger is removed from the touch panel 12, so that it is possible to prevent an erroneous operation even for an operation involving, for example, rotation of the panel display.

  In this embodiment, the in-vehicle audio apparatus has been described as an example. However, the use of the present invention is not limited to this, and an electronic apparatus having a touch panel display and capable of performing a physical processing operation. Any device can be applied.

  For example, an electronic device in which a navigation function and a moving image reproduction function are further added to the in-vehicle audio device may be used. In this case, the DVD drive may be configured not only to read music information from the DVD medium but also to read and reproduce / display moving picture and map information. In particular, since it is desired to enlarge the display for reproducing moving images and displaying map information, the effect of the application of the present invention can be obtained more remarkably.

  As described above, the electronic device according to the present invention is particularly useful for improving the operability in a small electronic device such as an in-vehicle audio.

It is a schematic block diagram which shows the schematic structure of the vehicle-mounted audio apparatus which concerns on this Embodiment.
