  Incidentally, the HDD of a portable HDD player is generally configured with a large capacity capable of recording 1000 or more songs. On the other hand, the display range on the display unit is about several songs even if it can be displayed at one time. Therefore, in the portable HDD player, when a desired song is played, it is necessary to scroll the display screen to change the display contents sequentially by the operation of the operation button, and to let the user select the song to be played.

  However, in the above-described method in which the display content of the display unit is changed only by manual operation, when 1000 or more songs are recorded on the HDD, the user can finally select a desired song while viewing the display unit. In this case, the operation button has to be pressed many times, and the operation is troublesome.

  The present invention has been made to solve the above-described problems, and its purpose is to reduce the user's operational burden when changing the display content of the display unit, thereby improving the convenience of the apparatus. It is an object of the present invention to provide an electronic device that can be made to operate.

  (1) An electronic apparatus according to the present invention is an electronic apparatus including a display unit that displays information and a control unit that controls display of information on the display unit, and detects an attitude change of the apparatus. The apparatus further includes a detection unit, and the control unit changes the display content of the information on the display unit in response to a change in the posture of the apparatus detected by the posture detection unit.

  According to the above configuration, when a change in the posture of the apparatus (for example, the inclination of the apparatus from the reference position) is detected by the posture detection means, the control means displays information on the display unit in response to the change in the posture. Change the content. Here, the change of the display content includes, for example, scrolling of the display content. This scroll includes not only the operation of sequentially shifting the display contents in one direction but also the operation of switching to the display showing the detailed contents of the information displayed on the display unit. In other words, the change in display content refers to a change in the displayed content itself, and is a concept different from a change in display direction (display content is the same) that changes from vertical writing to horizontal writing.

  In this way, the display content on the display unit changes only by changing the attitude of the device, so that the conventional cumbersome manual operation of pressing the operation button many times is not necessary when changing the display content. Can do. Therefore, according to the said structure, the operation burden of the user who uses an apparatus can be reduced, and the convenience of an apparatus can be improved.

  (2) In the electronic device of the present invention, the control unit may be configured to change the display content in a manner corresponding to a tilt direction from a reference position of the device. Note that the tilt direction of the apparatus can also be referred to as the rotation direction of the apparatus.

  For example, when the device is tilted (rotated) in any direction from the reference position, the control means sequentially shifts the display contents on the display unit, while the device is tilted in a direction different from the above direction from the reference position. In the case of (turned), the display contents on the display unit are further switched to the detailed display. Thus, since the control means changes the display content in a manner corresponding to the inclination direction from the reference position of the apparatus, it is possible to provide variations in how the display content is changed.

  (3) In the electronic device according to the present invention, the control means may be configured to scroll the display content in a direction corresponding to a tilt direction from a reference position of the device.

  For example, when the position of the device in which the display unit is in the vertical direction is set as the reference position, when the device is tilted from the reference position so that the display unit is directed upward, the control unit is configured in a direction corresponding to the tilt direction (for example, the display unit The display content is scrolled in the upward direction on the display screen. Therefore, the user can perform scrolling of the display contents with a simple operation of tilting the apparatus.

  (4) In the electronic device according to the present invention, the control unit may be configured to scroll the display content at a speed corresponding to an inclination amount from a reference position of the device.

  According to the above configuration, when the tilt amount from the reference position of the apparatus is small, the control means scrolls the display content at a small speed corresponding to the tilt amount, while when the tilt amount is large, The display contents are scrolled at a large speed corresponding to the tilt amount. Accordingly, the scrolling speed of the display content can be changed only by adjusting the tilt amount of the device, so that desired information required by the user can be displayed on the display unit more quickly.

  (5) In the electronic device according to the present invention, the control means may change the display content when the device is tilted by a predetermined amount in the direction opposite to the tilt direction of the device corresponding to the current scroll direction of the display content. The structure which stops a scroll may be sufficient.

  For example, when the current tilt direction of the device corresponds to the direction in which the display content is scrolled upward on the display unit, the tilt direction is such that the device scrolls in the direction opposite to the tilt direction (the scroll direction is scrolled downward). ), The control means stops the scrolling of the display content in the upward direction. Here, the predetermined amount may be, for example, an amount of inclination up to the original position (reference position) of the apparatus, or an amount of inclination up to a range where the reference position has a slight margin. May be. With such a configuration, it is possible to avoid the inconvenience that desired display content disappears from the display screen due to excessive scrolling by a simple operation (adjustment of the tilt direction of the apparatus). In addition, if the device is not tilted by a predetermined amount, the scrolling of the display contents will not stop. Therefore, the scroll speed can be finely adjusted by adjusting the tilt of the device within the range until the device tilt amount reaches the predetermined amount. You can also

  (6) The electronic device of the present invention further includes a reproducing unit that reproduces information selected and displayed on the display screen of the display unit, and the control unit corresponds to a current scrollable direction of the display content. When the apparatus is tilted in a direction different from the tilt direction of the apparatus, the information that is selected and displayed may be reproduced by the reproducing unit.

  According to the above configuration, when the device is tilted in a direction different from the tilt direction of the device corresponding to the scrollable direction (for example, the vertical scroll direction of the display content) of the current display content on the display unit, the control means controls Thus, the information (for example, music piece) selected and displayed on the display screen of the display unit is reproduced by the reproducing means. Thereby, the user can select desired information and reproduce it on the apparatus only by performing an operation of adjusting the tilt direction of the apparatus (without performing a complicated operation such as pressing an operation button).

  (7) An electronic device according to the present invention includes an operation unit for manually changing the display content, and a trigger unit for turning on / off the operation of the control unit based on detection of a posture change of the posture detection unit. May be provided.

  According to said structure, the user can change the display content in a display part by any one of the attitude | position change of an apparatus, and the manual operation in an operation part by operating a trigger means. . Thereby, the user can select an easy-to-use method and use the apparatus. For example, when the amount of information to be displayed on the display unit is originally small, there are cases where the device can be used more easily by changing the display content by an operation on the operation unit. Therefore, according to the above configuration, the convenience of the apparatus is increased in that both of the above methods can be selectively used.

  According to the present invention, since the display content on the display unit changes only by changing the attitude of the device, the cumbersome manual operation of pressing the operation button many times is not necessary when changing the display content. can do. As a result, the operation burden on the user who uses the apparatus can be reduced, and the convenience of the apparatus can be improved.

  An embodiment of the present invention will be described below with reference to the drawings.

  FIG. 2 is a perspective view showing an external configuration of a portable HDD player (also simply referred to as a device) as an example of an electronic device according to the present invention. This apparatus has a display unit 2 and an operation unit 3 on the same surface of a substantially rectangular parallelepiped main body 1.

  The display unit 2 displays information (for example, song title and track number) recorded in the HDD 11 to be described later, the current operation state of the device (for example, whether or not playback is in progress), and the like. It is configured. As the display data displayed on the display unit 2, for example, the same data as shown in FIGS. 8A to 8F can be considered.

  The operation unit 3 is manually pressed to change the display content on the display unit 2 and to control the operation of the apparatus. More specifically, the operation unit 3 includes a VOLUME (+) / up scroll key 4, an FF / right scroll key 5, a VOLUME (−) / down scroll key 6, a REW / left scroll key 7, and PLAY. A / PAUSE key 8 and a MENU key 9 are provided.

  The VOLUME (+) / up scroll key 4 is a key for increasing the volume and scrolling the display content on the display unit 2 upward. The FF / right scroll key 5 is a key for fast-forwarding the music to be reproduced and scrolling the display content on the display unit 2 in the right direction. The VOLUME (−) / down scroll key 6 is a key for volume down and scrolling the display content on the display unit 2 downward. The REW / left scroll key 7 is a key for rewinding the music to be reproduced and scrolling the display content on the display unit 2 in the left direction. The PLAY / PAUSE key 8 is a key for instructing playback and pause of the music selected and displayed on the display unit 2. In FIG. 2, the selection range in the display unit 2 is indicated by a mesh portion (the same applies to other drawings). The MENU key 9 is a key for causing the display unit 2 to display a menu screen (see FIG. 8A).

  A main body scroll ON / OFF button 10 is provided on one side surface of the main body 1. The main body scroll ON / OFF button 10 is a trigger means for turning ON / OFF the operation of the CPU 13 based on detection of a change in posture of an acceleration sensor 12 described later. For example, if the main body scroll ON / OFF button 10 is turned OFF, the user can manually input the operation unit 3 to change the display content on the display unit 2 or cause the apparatus to perform a predetermined operation. it can. On the other hand, if the main body scroll ON / OFF button 10 is turned on, the display content on the display unit 2 is changed based on the attitude detection of the apparatus under the control of the CPU 13. Although this point is the most characteristic part of the present invention, the detailed operation will be described later.

  By the way, as a change of the display content in the display part 2, there is scrolling of the display content as described above. This scroll includes a vertical scroll and a horizontal scroll. The scroll in the vertical direction is simply an operation of sequentially shifting the display contents in the vertical direction. On the other hand, scrolling to the right includes not only the operation of sequentially shifting the display content to the right, but also the operation of switching to a display showing the detailed content of the information displayed on the display unit. Further, the scrolling to the left includes not only the operation of sequentially shifting the display contents to the left, but also the operation of switching the display to the category (folder) including the above information.

  Next, the internal configuration of the portable HDD player will be described with reference to FIG. FIG. 1 is a block diagram showing an electrical connection configuration inside a portable HDD player.

  The portable HDD player includes an HDD 11, an acceleration sensor 12, a CPU 13, and a memory 14 in addition to the display unit 2, the operation unit 3, and the main body scroll ON / OFF button 10.

  The HDD 11 can record, for example, music data of 1000 songs or more, but also functions as a playback unit that plays back information (song) selected and displayed on the display screen of the display unit 2.

  The acceleration sensor 12 is posture detection means for detecting a change in the posture of the apparatus. More specifically, the acceleration sensor 12 detects the tilt direction of the device (hereinafter referred to as the X direction) corresponding to the up / down scroll direction on the display unit 2 and also the tilt direction of the device corresponding to the left / right scroll direction. (Hereinafter referred to as the Y direction) is detected, and a voltage corresponding to the amount of inclination (tilt angle) of the device in each of the X direction and the Y direction is output to the CPU 13. Such detection of the tilt directions in the X direction and the Y direction can be performed by appropriately setting the mounting direction of the acceleration sensor 12 on a substrate (not shown). Further, if the direction in which the acceleration sensor 12 is mounted on the substrate is changed, it is possible to detect the tilt direction of the apparatus different from the tilt direction.

  Here, in FIGS. 3A, 3B, and 3C, the position of the apparatus in which the display unit 2 and the operation unit 3 face the front is used as a reference position, and the display unit 2 and the operation unit 3 gradually turn upward. Thus, the side views of the apparatus when the upper part of the main body 1 of the apparatus is tilted from the reference position with the horizontal direction as the rotation axis are respectively shown. In the present embodiment, the X direction indicates a direction in which the upper portion of the main body 1 rotates toward the front or the back side with the horizontal rotation axis as a center. The more the device is rotated forward, the larger the output value in the X direction of the acceleration sensor 12 is, and the more the device is rotated in the back, the smaller the output value in the X direction of the acceleration sensor 12 is. . The increase / decrease direction of the output value in the X direction can be changed by changing the direction in which the acceleration sensor 12 is attached to the substrate.

  FIG. 4A shows a bottom view of the apparatus in the state of FIG. 3A, and FIG. 4B shows the right end (or left end) of the apparatus as a reference with the vertical direction as the rotation axis. The bottom view of an apparatus at the time of rotating from a position is shown. In the present embodiment, the Y direction indicates a direction in which the right end of the apparatus rotates toward the front or the back side about the vertical rotation axis. Then, the more the right end of the device is rotated forward, the larger the output value in the Y direction of the acceleration sensor 12, and the more the right end of the device is rotated inward, the more the output in the Y direction of the acceleration sensor 12 is. The value becomes smaller. The increase / decrease direction of the output value in the Y direction can be changed by changing the direction in which the acceleration sensor 12 is attached to the substrate.

  The CPU 13 is a control unit that controls display of information on the display unit 2, and creates appropriate data to be displayed on the display unit 2. In addition to controlling the operation of each unit, the CPU 13 performs processing for expanding music data, processing corresponding to input from the operation unit 3, processing for input from the main body scroll ON / OFF button 10, input from the acceleration sensor 12. The process etc. are also performed.

  The memory 14 stores a program for operating the CPU 13 and saves data necessary for the music data expansion process.

  Next, the operation of the apparatus in this embodiment will be described. In the following description, in order to facilitate understanding of the description, it is assumed that the display state of the display unit 2 is a state in which a music title name is displayed as shown in FIG.

  In order to select a song that the user wants to play, first, the main body scroll ON / OFF button 10 of the apparatus is pressed to turn on the main body scroll. Thereby, the scroll of the display screen currently displayed on the display part 2 will be in the state which can change according to the state (attitude) of an apparatus.

  Here, it is assumed that the main body scroll is turned on in the state shown in FIG. The CPU 13 stores the output value A in the X direction and the output value a in the Y direction of the acceleration sensor 12 at this time. When the apparatus is tilted from the state of FIG. 3A to the state of FIG. 3B, the output value in the X direction of the acceleration sensor 12 is smaller than the output value A obtained in the state of FIG. The output value is B. The CPU 13 compares the output value A with the output value B, and performs control to scroll the display content of the display unit 2 upward because the output value B is smaller. As a result, the display on the display unit 2 is scrolled upward.

  When the apparatus is further tilted to the state shown in FIG. 3C, the output value in the X direction of the acceleration sensor 12 becomes an output value C that is smaller than the output value B. The CPU 13 compares the output value A with the output value C, and performs control to scroll the display content of the display unit 2 further upward because the output value C is smaller. As a result, the display on the display unit 2 is further scrolled upward.

  Here, the difference between the output value A and the output value B is different from the difference between the output value A and the output value C. Utilizing this fact, the CPU 13 can also perform control to increase the scrolling speed as the difference between the output values increases. That is, the CPU 13 can scroll the display content of the display unit 2 at a speed corresponding to the amount of inclination from the reference position of the apparatus. In this case, it is possible to change the scroll speed of the display contents only by adjusting the tilt amount of the apparatus, so that desired information required by the user can be displayed on the display unit 2 earlier.

  If the device is kept tilted, the display content of the display unit 2 continues to scroll upward, so that when the desired song is displayed on the display unit 2, the posture of the device is as shown in FIG. By returning to the above, the scrolling is stopped. Here, if it does not return to the state of Fig.3 (a) correctly, it does not stop, but a user's usability increases by giving some margin.

  In this way, the CPU 13 reverses the direction (X in which the output value decreases in the X direction) opposite to the current scroll direction (upward in the above example) of the display content on the display unit 2 (X direction). The scrolling of the display content may be stopped when the apparatus is tilted by a predetermined amount in the direction in which the output value increases. Thereby, it is possible to avoid the inconvenience that the desired display content is not displayed on the display unit 2 due to excessive scrolling (the display passes) by a simple operation (adjustment of the tilt direction of the apparatus). If the device is not tilted by a predetermined amount, the scrolling of the displayed contents will not stop. Therefore, by adjusting the tilt of the device within the range until the tilt amount of the device reaches the predetermined amount, the scroll speed can be increased or decreased. Adjustments can also be made.

  At this time, the CPU 13 increases the output value in the direction different from the tilt direction of the device corresponding to the current scroll direction of the display content on the display unit 2 (for example, the direction in which the output value decreases in the X direction). The scrolling of the display content may be stopped at the moment when the device is tilted in the direction or the Y direction. Even in this case, the inconvenience that desired display content is not displayed on the display unit 2 due to excessive scrolling can be avoided by a simple operation.

  On the other hand, when scrolling the display content of the display unit 2 and selecting a song, if the main body scroll is turned on in the state of FIG. 3A, the apparatus is brought into the state of FIG. do it. That is, when the apparatus is tilted from the state of FIG. 3A to the state of FIG. 5A, the output value in the X direction of the acceleration sensor 12 is greater than the output value A obtained in the state of FIG. Becomes a large output value D. The CPU 13 compares the output value A with the output value D, and performs control to scroll the display content of the display unit 2 downward because the output value D is larger. As a result, the display on the display unit 2 is scrolled downward.

  When the apparatus is further tilted to the state of FIG. 5B, the output value in the X direction of the acceleration sensor 12 becomes an output value E that is larger than the output value D. The CPU 13 compares the output value A with the output value E, and the output value E is larger, so that the display content of the display unit 2 is further scrolled downward. As a result, the display on the display unit 2 is further scrolled downward.

  At this time, since the difference between the output value A and the output value D is different from the difference between the output value A and the output value E, the CPU 13 performs control to increase the scroll speed as the difference between the output values increases. As in the case of upward scrolling, the scrolling speed may be changed according to the tilt angle of the apparatus. Also, the method similar to the method described in the case of the up scroll can be applied to the method of stopping the down scroll.

  As described above, when a desired song appears on the display screen of the display unit 2 and falls within the selection range in the display screen, the CPU 13 performs the following control in accordance with the inclination of the apparatus.

  Now, assume that scrolling in the vertical direction is stopped in the state of FIG. The output value in the Y direction of the acceleration sensor 12 at this time is a. When the apparatus is tilted and the state shown in FIG. 4B is obtained, the output value in the Y direction of the acceleration sensor 12 becomes an output value b smaller than the output value a shown in FIG. The CPU 13 compares the output value “a” with the output value “b”. Since the output value “b” is smaller, the CPU 13 performs the reproduction process of the desired song that is finally selected.

  At this time, the tilt direction of the apparatus is a Y direction different from the X direction corresponding to the scrollable direction (that is, the vertical scroll direction) of the current display content on the display unit 2. At this time, the CPU 13 2, the process of causing the HDD 11 to reproduce the information finally selected and displayed is performed. Note that the information finally selected and displayed means information displayed on the display unit 2 and no further switching to the detailed display of the information. As a result, the user can select a desired piece of music and reproduce it on the apparatus without performing a complicated operation on the operation unit 3 simply by adjusting the tilt direction of the apparatus.

  When the above reproduction process is performed, the apparatus automatically enters a state where the main body scroll is OFF. It is also possible to turn off the main body scroll at any time by pressing the main body scroll ON / OFF button 10 by the user.

  In the above, the control when the display data displayed on the display unit 2 is already in the state of FIG. 8E has been described, but the display contents are shown in FIG. 8A, FIG. 8B, FIG. This embodiment also applies to the case where the transition is made in the order of (c) and FIG. 8 (e), and the case where the transition is made in the order of FIG. 8 (a), FIG. 8 (b), FIG. 8 (d) and FIG. The display contents can be changed by the inclination of the device in the same manner as in FIG. For example, in each figure, scrolling up and down is performed by tilting the device in the X direction (see FIGS. 3B and 5C and FIGS. 5A and 5B), and right scrolling (switching to detailed display). ) Can be performed by tilting the device in the Y direction (see FIGS. 4A and 4B).

  From the above, the apparatus is tilted in the X direction to the state shown in FIGS. 3A to 3B and 3C when the VOLUME (+) / up scroll key 4 in FIG. 2 is pressed. The tilting of the device in the X direction to the state shown in FIGS. 3A to 5A and 5B corresponds to the case where the VOLUME (−) / down scroll key 6 is pressed. I can say that. Moreover, it can be said that tilting the device in the Y direction to the state shown in FIGS. 4A to 4B corresponds to the case where the FF / right scroll key 5 or the PLAY / PAUSE key 8 is pressed. . Note that tilting the device in the direction opposite to that in FIG. 4B corresponds to the case where the REW / left scroll key 7 is pressed.

  As described above, in the apparatus according to the present embodiment, the CPU 13 changes the display content of information on the display unit 2 in response to the change in the attitude of the apparatus detected by the acceleration sensor 12. As a result, the display content on the display unit 2 changes only by changing the orientation of the apparatus, and therefore, there is no need for troublesome manual operations such as pressing each key of the operation unit 3 many times when changing the display content. can do. Therefore, the operation burden on the user who uses the apparatus can be reduced, and the convenience of the apparatus can be improved.

  Further, the CPU 13 scrolls the display content of the display unit 2 in the vertical direction if the tilt of the device is in the X direction, and controls to switch the display content to the detailed display if the tilt of the device is in the Y direction. . Thus, since the CPU 13 changes the display content of the display unit 2 in a manner corresponding to the tilt direction from the reference position of the apparatus, various variations can be realized when the display content changes.

  Further, the CPU 13 scrolls the display content of the display unit 2 in a direction corresponding to the tilt direction from the reference position of the apparatus. Therefore, the user can cause the display content to be scrolled in a predetermined direction (a direction corresponding to the tilt direction) with a simple operation of tilting the apparatus.

  The apparatus according to the present embodiment also includes an operation unit 3 for manually changing the display content of the display unit 2 and a main body scroll ON for turning on / off the operation of the CPU 13 based on detection of the posture change of the acceleration sensor 12. / OFF button 10 is provided. Thereby, the user operates the main body scroll ON / OFF button 10 to change the display content on the display unit 2 by either one of the attitude change of the apparatus and the manual operation on the operation unit 3. be able to. Therefore, the user can select an easy-to-use method to use the apparatus, and the convenience of the apparatus increases more and more.

  In the present embodiment, the acceleration sensor 12 is incorporated in the device, and the method of scrolling the display screen in the display unit 2 corresponding to the tilt of the device has been described. However, the acceleration is not transmitted to the remote controller connected to the device but the device. By providing the sensor 12 and the main body scroll ON / OFF button 10 and supplying the output of the acceleration sensor 12 to the apparatus, it is also possible to perform scroll control of the display content of the display unit 2 by tilting the remote controller.
