  FIG. 1 is a diagram showing an appearance of a display device 1 according to an embodiment of the present invention. The display device 1 includes a display panel unit 11 and a main body unit 12. The display panel unit 11 includes an LCD (Liquid Crystal Display) and displays an image. The display panel unit 11 is formed to be a square when viewed from the front.

  The main body 12 controls display of images on the display panel unit 11 and functions as a pedestal that supports the display panel unit 11.

  The main body 12 supports the display panel 11 so that it can rotate with respect to the main body 12.

  In the state where the screen 15 of the display panel unit 11 is horizontally long, the left and right side surfaces and the upper and lower side surfaces of the display panel unit 11 form one plane with the left and right side surfaces and the upper and lower side surfaces of the main body unit 12, respectively. To do. Even when the display panel unit 11 is rotated and the screen 15 of the display panel unit 11 is vertically long, the left and right side surfaces and the upper and lower side surfaces of the display panel unit 11 are the left and right side surfaces of the main body unit 12 and One plane is formed with each of the upper and lower side surfaces.

  A screen having the short side of the screen 15 as vertical and the long side of the screen 15 as horizontal is referred to as a horizontally long screen, and the screen having the short side of the screen 15 as horizontal and the long side of the screen 15 as vertical is referred to as a vertically long screen. This is called a screen.

  The logo display unit 13 displays a mark when the screen 15 of the display panel unit 11 is horizontally long. The logo display unit 14 displays a mark when the screen 15 of the display panel unit 11 is vertically long. The mark is a mark referred to in the trademark law, and is a character, a figure, a symbol, a three-dimensional shape, a combination thereof, or a combination of these and a color.

  For example, the logo display unit 13 and the logo display unit 14 include a portion that transmits light in the shape of a mark and a portion that does not transmit light, and the logo display unit 13 and the logo display unit are disposed inside the display panel unit 11. The mark is displayed by causing the light source provided for each of the 14 to emit light.

  Hereinafter, the mark displayed on the logo display unit 13 when the screen 15 of the display panel unit 11 is horizontally long is also referred to as a horizontal screen logo, and the logo display unit 14 when the screen 15 of the display panel unit 11 is vertically long. The mark displayed on is also referred to as a vertical screen logo.

  The screen 15 is an area where an image is displayed. The aspect ratio of the screen 15 is 3 to 4.

  FIG. 2 is a diagram illustrating an internal mechanism of the display device 1. Inside the display device 1, a slider 31, a panel body connecting shaft 32, a guide rail 33, a spring 34, a damper 35, a guide 36, and a bearing 37 are provided. FIG. 3 is an enlarged view showing the configuration of the slider 31, the panel body connecting shaft 32, the guide rail 33, the spring 34, the damper 35, the guide 36, and the bearing 37.

  The slider 31 holds the panel body connecting shaft 32 so as to be movable up and down. That is, the slider 31 supports the panel main body connection shaft 32 and is provided so as to be movable up and down along the guide rail 33.

  The panel main body connection shaft 32 is a pivot point of the display panel unit 11 (the sliding tape portion in the figure), and pivotally supports the display panel unit 11. For example, the portion supported by the slider 31 of the panel body connecting shaft 32 is formed in a circular shape. A portion of the panel main body connecting shaft 32 supported by the slider 31 is fitted in a hole of the slider 31 formed in a circle corresponding to this portion, so that the panel main body connecting shaft 32 is rotatable with respect to the slider 31. And is held by the slider 31.

  The guide rail 33 is provided in the main body 12 and fits to both the left and right sides of the slider 31 to restrict the trajectory of the slider 31 moving in the vertical direction. In the example shown in FIGS. 2 and 3, the guide rail 33 regulates the locus of movement of the slider 31 so that the slider 31 moves up and down on a straight line in the vertical direction.

  The spring 34 is a so-called coil spring. One end of the spring 34 is fixed to the portion of the main body 12 above the slider 31, and the other end is fixed to the slider 31. The spring 34 applies a biasing force in the pulling direction to the main body 12 and the slider 31. That is, the spring 34 applies an upward force to the slider 31.

  If the magnitude of the upward force applied to the slider 31 by the spring 34 cancels the weight of the display panel unit 11, the user can lightly rotate the display panel unit 11, for example, with one finger. Can be made.

  The spring 34 only needs to apply an upward force to the slider 31, and is not limited to a coil spring but may be a torsion spring or a spiral spring. In place of the spring 34, an air cylinder may be provided. Furthermore, an upward force may be applied to the slider 31 by an elastic body such as rubber. Furthermore, an upward force may be applied to the slider 31 using a repulsive force or attractive force of magnetic force.

  The right end of the slider 31 is a rack 31A that is a flat plate provided with teeth. The teeth of the rack 31A mesh with the gear 35A of the damper 35 that is a pinion. The damper 35 gives resistance when the gear 35A of the damper 35 rotates counterclockwise in the figure, and does not give resistance when the gear 35A of the damper 35 rotates clockwise in the figure. That is, the damper 35 suppresses the speed at which the slider 31 descends by applying resistance to the gear 35A meshing with the rack 31A.

  Thereby, when the display panel part 11 descend | falls, it can prevent that the display panel part 11 falls suddenly with its own weight, or rotates. As a result, when the user rotates the display panel unit 11, for example, the user can be prevented from getting injured with a finger between the display panel unit 11 and the main body unit 12, and the display panel can be more safely operated. The part 11 can be rotated.

  The damper 35 is not limited to a rotary type, and may be a direct acting type. The damper 35 may be any type that utilizes solid friction, fluid friction, or magnetism.

  The guide 36 is provided in the main body 12 integrally with the guide rail 33. The guide 36 is arranged so that the display panel unit 11 is lifted with respect to the main body unit 12 when the display panel unit 11 is rotated and is tilted with respect to the main body unit 12. Regulate the vertical position. If it demonstrates in detail, the guide 36 is formed so that the center part may become high and the both sides may become low. The guide 36 has a shape that sandwiches a bearing 37 that is fixed to the main body 12 from the upper side and the lower side.

  When the display panel unit 11 is rotated, the bearing 37 slides inside the guide 36. When the bearing 37 moves while sliding inside the guide 36, the vertical position of the bearing 37 is regulated by the guide 36. In other words, the vertical position of the bearing 37 is increased at the center of the guide 36, and the vertical position of the bearing 37 is decreased at both ends of the guide 36.

  Since the bearing 37 is fixed to the display panel unit 11, when the bearing 37 moves along the guide 36, the height of the display panel unit 11 changes.

  In this way, the display panel unit 11 is pivotally supported by the panel body connecting shaft 32. The slider 31 holds the panel body connecting shaft 32 so as to be movable up and down. The position of the slider 31 is regulated by the guide rail 33 so as to move on a straight line in the vertical direction. Further, the vertical position of the display panel unit 11 is regulated by the guide 36.

  As shown on the left side of FIG. 4, in the state where the screen 15 of the display panel unit 11 is horizontally long, the display panel unit 11 is positioned at the same height as the main body unit 12. In this case, each of the left and right side surfaces and the upper and lower side surfaces of the display panel unit 11 forms one plane with each of the left and right side surfaces and the upper and lower side surfaces of the main body unit 12.

  When the display panel unit 11 is rotated clockwise by the user, the bearing 37 is lifted by the guide 36, so that the display panel unit 11 rises with respect to the main body unit 12.

  When the display panel unit 11 is rotated clockwise up to 45 degrees from the state in which the screen 15 is horizontally long, the display panel unit 11 is at the highest position with respect to the main body unit 12 as shown in the center of FIG. To rise.

  Thereby, it can prevent that the display panel part 11 collides with the surface in which the display apparatus 1 is installed.

  The angle formed by the surface on which the display device 1 is installed and the axis parallel to the longitudinal direction of the screen 15 of the display panel unit 11 is referred to as the angle of the display panel unit 11. For example, the angle of the display panel unit 11 when the screen 15 is horizontally long is referred to as 0 degrees, and the angle of the display panel unit 11 when the screen 15 is vertically long is referred to as 90 degrees.

  When the display panel unit 11 is further rotated clockwise beyond 45 degrees, the bearing 37 is pushed down by the guide 36, so that the display panel unit 11 is lowered with respect to the main body unit 12.

  When the display panel unit 11 is turned 90 degrees from the state in which the screen 15 is horizontally long and the screen 15 is in the state in which the screen 15 is vertically long, the height of the display panel unit 11 is the same as the height in the state in which the screen 15 is horizontally long. It will be the same.

  As a result, in the state where the screen 15 is vertically long, each of the left and right side surfaces and the upper and lower side surfaces of the display panel unit 11 forms one plane with each of the left and right side surfaces and the upper and lower side surfaces of the main body unit 12.

  Even when the display panel unit 11 is rotated counterclockwise up to 45 degrees from the state in which the screen 15 is vertically long, as shown in the center of FIG. Ascend to the highest position.

  Further, when the display panel unit 11 is rotated counterclockwise, the bearing 37 is pushed down by the guide 36, so that the display panel unit 11 is lowered with respect to the main body unit 12.

  Even when the display panel unit 11 is rotated counterclockwise from the state in which the screen 15 is vertically long, the display panel unit 11 can be prevented from colliding with the surface on which the display device 1 is installed.

  FIG. 5 is a diagram illustrating the position of the rotated display panel unit 11. As shown in FIG. 5, when the display panel unit 11 is rotated, the lowest part of the display panel unit 11 has a certain height. For example, when the display panel unit 11 is rotated, the position of the lowest part of the display panel unit 11 is the same as that of the side surface below the display panel unit 11 in the state where the screen 15 is vertically long or horizontally long. It coincides with the position of the lower side surface of the main body portion 12 forming one surface.

  Thereby, when rotating the display panel part 11, the impression which is rotating more beautifully can be given to a user. In addition, the display panel unit 11 can be rotated more safely without a hand being sandwiched between the display panel unit 11 and the surface on which the display device 1 is installed.

  As shown in FIG. 5, the display panel unit 11 hides the guide 36 regardless of the angle of the display panel unit 11 with respect to the main body unit 12 from 0 degrees to 90 degrees.

  That is, the guide 36 regulates the vertical position of the display panel unit 11 so that the guide 36 is hidden by the display panel unit 11 when the display panel unit 11 is rotated.

  Thereby, when rotating the display panel part 11, the beauty | look of the display apparatus 1 is not impaired.

  At the beginning of the rotation of the display panel unit 11, when the display panel unit 11 is rotated, the display panel unit 11 is lifted, so that only the slider 31, the panel body connecting shaft 32, the guide rail 33, the guide 36, and the bearing 37 are used. If the user does not apply a force that supports the weight of the display panel unit 11, the display panel unit 11 cannot be rotated.

  The display device 1 is provided with a spring 34 and a damper 35 so that the display panel unit 11 can be smoothly rotated with less force.

  Since the spring 34 applies an upward force to the slider 31, the display panel unit 11 can be rotated more lightly when the display panel unit 11 rises and starts to rotate. For example, when the display panel unit 11 is rotated from a state in which the screen 15 is horizontally long to a state in which the screen 15 is vertically long, the display panel unit 11 is in a state where the angle of the display panel unit 11 is 0 degree to 45 degrees. To rise. In this case, the display panel unit 11 is raised by an upward force applied by the spring 34 in addition to the force by the user.

  The user can rotate the display panel unit 11 with less force by the upward force applied by the spring 34.

  On the other hand, when the display panel unit 11 is rotated, the display panel unit 11 tends to be lowered. Therefore, when only the slider 31, the panel body connecting shaft 32, the guide rail 33, the guide 36, and the bearing 37 are provided. If the user does not apply a force that supports the weight of the display panel unit 11, the display panel unit 11 cannot be slowly rotated.

  Therefore, a damper 35 is provided to suppress the speed at which the slider 31 descends. The damper 35 suppresses the lowering speed of the slider 31, so that the display panel unit 11 descends, and at the end of rotation, the display panel unit 11 is lighter even if the user does not support all the weight of the display panel unit 11. The panel part 11 can be slowly rotated. For example, when the display panel unit 11 is rotated from a state in which the screen 15 is horizontally long to a state in which the screen 15 is vertically long, the display panel unit 11 is in a state where the angle of the display panel unit 11 is 45 degrees to 90 degrees. Descend. In this case, the lowering speed of the display panel unit 11 is suppressed by the damper 35 in addition to the force by the user and the weight of the display panel unit 11.

  The user can slowly rotate the display panel unit 11 with less force or only the weight of the display panel unit 11 by the amount suppressed by the damper 35.

  FIG. 6 shows the magnitude of the upward force applied by the spring 34 and the rotation of the display panel 11 when the damper 35 has a characteristic that suppresses the lowering speed of the slider 31, that is, when the damping characteristic is constant. The relationship between the force required at the beginning and the magnitude of the upward force applied by the spring 34 and the time required until the display panel unit 11 is fully lowered will be shown.

  The lower axis in the figure indicates the magnitude of the upward force applied by the spring 34 (assist spring force in the figure) [N]. The right axis in the figure indicates the force [N] required to start the display panel unit 11 to rotate. The left axis in the figure indicates the time (fall time) [seconds] required until the display panel unit 11 is fully lowered.

  A point indicated by a triangle in the figure indicates a force [N] required to start the rotation of the display panel unit 11 with respect to the magnitude [N] of the upward force applied by the spring 34. A point indicated by a square in the figure indicates a time [second] required for the display panel unit 11 to be fully lowered with respect to the magnitude [N] of the upward force applied by the spring 34.

  When an upward force of about 11N is applied by the spring 34, the force required to start the display panel unit 11 to rotate is about 16N. When an upward force of about 13N is applied by the spring 34, the force required to start the display panel unit 11 to rotate is about 15.5N. Similarly, when an upward force of about 15N or about 18N is applied by the spring 34, the force required to start the rotation of the display panel unit 11 is about 14.5N or about 13N, respectively.

  When the force required to start the display panel unit 11 is small, the user feels the display panel unit 11 lightly, and when the force required to start the display panel unit 11 is large. Feel the display panel unit 11 heavy.

  When an upward force of about 11 N is applied by the spring 34, the time required for the display panel unit 11 to be lowered is about 2.5 seconds. When an upward force of about 13N is applied by the spring 34, the time required for the display panel unit 11 to be lowered is about 3 seconds. Similarly, when an upward force of about 15 N or about 18 N is applied by the spring 34, the time required for the display panel unit 11 to be fully lowered is about 3.5 seconds or about 5 seconds, respectively.

  When the time required for the display panel unit 11 to be lowered is short, the user feels the speed at which the display panel unit 11 is lowered, and when the time required for the display panel unit 11 to be lowered is long. I feel the speed of the display panel 11 descending slowly.

  By adjusting the damping characteristic of the slider 31 and the magnitude of the upward force applied by the spring 34, the display panel unit 11 can be rotated at a more appropriate speed with a more appropriate weight. .

  For example, as an optimum operating point, in FIG. 6, a triangle indicating the force [N] required to start the display panel unit 11 to rotate with respect to the magnitude [N] of the upward force applied by the spring 34 is shown. A line connecting the points indicated by the squares indicating the time [seconds] required for the display panel unit 11 to be fully lowered with respect to the magnitude [N] of the upward force applied by the spring 34 Can be selected. For example, in this case, the force required to start the rotation of the display panel unit 11 is about 14.5 N, and the time required for the display panel unit 11 to be lowered is about 3.5 seconds.

  When the display panel unit 11 is rotated, the damping characteristic of the slider 31 and the magnitude of the upward force applied by the spring 34 can be adjusted so that the user feels better.

  When the display panel unit 11 is heavy, the effect of providing the spring 34 and the damper 35 is further increased. For example, it is more effective when the screen 15 is larger or when the density of the material forming the display panel unit 11 is larger.

  Furthermore, the display panel unit 11 can be rotated more smoothly.

  FIG. 7 is a diagram showing a sliding tape provided in the display panel unit 11. FIG. 8 is a view showing a support portion provided in the main body portion 12.

  The sliding tapes 51-1 to 51-4 are made of a material that has a small coefficient of friction and is not easily worn, such as polyethylene, fluororesin, or nylon. The sliding tapes 51-1 to 51-4 are attached to the surface of the display panel unit 11 that faces the main body unit 12.

  The support portions 61-1 to 61-4 are made of a material that is excellent in workability, such as polyacetal (POM: polyoxymethylene) resin, has a small friction coefficient, and is not easily worn. The support portions 61-1 to 61-4 are provided on the surface of the main body portion 12 and facing the display panel portion 11. For example, the support portions 61-1 to 61-4 are formed integrally with the guide rail 33 and the guide 36.

  When the display panel unit 11 is rotated, the support unit 61-1 and the sliding tape 51-1 are in a state in which the support unit 61-1 and the sliding tape 51-1 are in contact with each other in the vertical direction with respect to the rotation direction of the display panel unit 11. 1 is provided at a corresponding position so as to slide on the sliding tape 51-1. Similarly, each of the support part 61-2 to the support part 61-4 and each of the sliding tape 51-2 to the sliding tape 51-4 are arranged so that the display panel part 11 is rotated when the display panel part 11 is rotated. Each of the support portions 61-2 to 61-4 slides on each of the sliding tape 51-2 to the sliding tape 51-4 in a state in which it is struck in a direction perpendicular to the direction of rotation. Are provided at corresponding positions.

  Since each of the sliding tape 51-1 to the sliding tape 51-4 and each of the support portions 61-1 to 61-4 abut, when the display panel portion 11 is rotated, the display with respect to the main body portion 12 is displayed. The shake (backlash) in the vertical direction with respect to the direction of rotation of the panel unit 11 can be suppressed.

  As a result, it is possible to prevent the display panel unit 11 from rattling when it is rotated, and to rotate the display panel unit 11 more smoothly.

  Further, the guide 36 moves the vertical position of the display panel unit 11 so that the support unit 61-2 to the support unit 61-4 are hidden by the display panel unit 11 when the display panel unit 11 is rotated. regulate.

If it is determined in step S12 that the angle of the display panel unit 11 is less than 20 degrees, the display panel unit 11 proceeds to step S13 because the screen 15 is in a horizontally long state, and the logo illumination lighting control unit 184 Then, the logo illumination unit 102 that illuminates the logo for the horizontal screen is turned on so as to be gradually brightened. That is, in step S13, the logo illumination lighting control unit 184 turns on the logo illumination unit 102 that illuminates the logo display unit 13 that displays the mark from the inside so as to gradually brighten.

  In step S14, the backlight lighting control unit 183 turns on the backlight 104.

  In step S <b> 15, the display instruction unit 185 instructs the motherboard 122 to display an image on the horizontally long screen 15. The operating system 201 instructed to display an image on the horizontally long screen 15 causes the display panel unit 11 to display an image on the horizontally long screen 15, and the process ends.

  As described above, when the display device 1 is activated in a state where the screen 15 is horizontally long, the mark is displayed on the logo display unit 13 before the image is displayed on the screen 15.

  In this way, when the display device 1 is activated in a state where the screen 15 is vertically long, the mark is displayed on the logo display unit 14 before the image is displayed on the screen 15.

  If it is determined in step S16 that the angle of the display panel unit 11 is less than 70 degrees, the angle of the display panel unit 11 is not less than 20 degrees and less than 70 degrees, so the logo illumination unit 102, the logo illumination unit 103, the back The process ends without turning on the light 104. In this case, when the display panel unit 11 is rotated by the user until the angle is less than 20 degrees or 70 degrees or more, the illumination switching process and the screen switching instruction process described below are performed. The logo illumination unit 102, the logo illumination unit 103, or the backlight 104 is turned on.

  As described above, since the mark is displayed on the logo display unit 13 or the logo display unit 14 before the image is displayed on the screen 15, the user can determine whether the screen 15 is in a horizontally long state or a vertically long state. Can be known before an image is displayed on the screen 15. For example, if the color of the screen 15 that is not displaying an image and the color of the display panel unit 11 are the same color, whether the screen 15 is in a horizontally long state or a vertically long state at first glance. I can't know. In such a case, before the image is displayed on the screen 15, the user feels uncomfortable with the displayed image by knowing whether the screen 15 is in a horizontally long state or a vertically long state. Is less.

  Further, as described above, the display panel unit 11 is pivotally supported by the panel main body connection shaft 32, the slider 31 holds the panel main body connection shaft 32 so as to be movable up and down, and the position of the slider 31 is up and down. The display panel portion 11 is regulated by the guide rail 33 so as to move on a straight line in the direction, and the vertical position of the display panel portion 11 is regulated by the guide 36. 11 can be rotated. Since the display panel unit 11 is rotated with the direction of rotation being constant, switching of the image display direction is not instructed many times, and the image display can be performed reliably and in a short time. The direction can be switched.

  Further, since the display direction of the image is switched when the backlight 104 is turned off, a distorted image is not displayed, and the screen can be switched without impairing the aesthetic appearance of the display device 1.

  FIG. 16 is a flowchart for explaining screen switching processing. In step S81, the operating system 201 determines whether or not the microcomputer 121 has instructed switching of the image display direction so that the image is displayed with the screen 15 being vertically long.

  If it is determined in step S81 that switching of the image display direction has been instructed to display the image with the screen 15 being vertically long, the process proceeds to step S82, and the application program execution control unit 221 of the operating system 201 The program 202 stops the slide show being executed. The application program 202 stops the slide show when the slide show is being executed, and continues the currently executed process when the slide show is not being executed.

  In step S <b> 83, the screen direction switching unit 222 of the operating system 201 switches the image display direction so that the screen 15 is displayed vertically and the image is displayed. In step S84, the application program execution control unit 221 of the operating system 201 causes the application program 202 to display a still image on the entire screen, returns to step S81, and repeats the above-described processing. For example, in step S84, the application program execution control unit 221 causes the application program 202 to display the still image that was displayed in the slide show before stopping the slide show on the entire screen. The application program 202 displays a still image on the screen 15 of the display panel unit 11 in a vertically long state on the full screen.

  If it is determined in step S81 that switching of the display direction of the image is not instructed so that the screen 15 is displayed vertically, the process proceeds to step S85, and the operating system 201 receives the screen from the microcomputer 121. It is determined whether or not an instruction to switch the display direction of the image has been instructed so that the image is displayed with 15 being horizontally long.

  If it is determined in step S85 that switching of the image display direction has been instructed so that the image is displayed with the screen 15 being landscape, the process proceeds to step S86, and the application program execution control unit 221 of the operating system 201 The program 202 stops the slide show being executed. The application program 202 stops the slide show when the slide show is being executed, and continues the currently executed process when the slide show is not being executed.

  In step S87, the screen direction switching unit 222 of the operating system 201 switches the display direction of the image so that the image is displayed with the screen 15 being landscape. In step S88, the application program execution control unit 221 of the operating system 201 causes the application program 202 to display a still image on the entire screen, returns to step S81, and repeats the above-described processing. For example, in step S88, the application program execution control unit 221 causes the application program 202 to display the still image that was displayed in the slide show before stopping the slide show on the entire screen. The application program 202 displays the still image on the screen 15 of the display panel unit 11 that is in the landscape state.

  If it is determined in step S85 that switching of the image display direction is not instructed so that the image is displayed with the screen 15 being landscape, the process returns to step S81 and the above-described processing is repeated.

  In this way, the image display direction is switched after the slide show being executed is stopped. When the image display direction is switched, a still image is displayed in full screen. That is, when the orientation of the image displayed on the display panel unit 11 is switched, the display process corresponding to the elapse of time that is continuously executed is stopped, and the display process that is not related to the elapse of time is executed. As a result, it is possible to reliably execute the process of switching the display direction of an image that requires a calculation amount.

  If the process of switching the display direction of the image is executed while the display process corresponding to the elapsed time is being executed, a large calculation load is applied. As a result, the image display is performed. The direction switching process may stop halfway.

  By stopping the display process corresponding to the lapse of time being continuously executed, the process of switching the display direction of the image is reliably executed.

  In addition, since the still image is displayed on the full screen after the process of switching the display direction of the image, the user can continue to view the image.

  As described above, appropriate delay and hysteresis control are performed for image display and mark display, so chattering is prevented and display can be switched smoothly.

  According to the present invention, even when a large number of mixed vertically long images or horizontally long images are displayed, it is possible to easily view a high-quality and larger displayed image.

  Thus, when the display of the display unit is controlled so as to switch the orientation of the displayed image, the orientation of the image can be switched. In addition, when the display unit is pivotally supported and the pivot support means is held up and down, and the display unit is rotated and tilted with respect to the pedestal, the display unit is supported with respect to the pedestal. The position of the display unit in the vertical direction is regulated so that the display unit is raised, the rotation angle of the display unit is detected, and the direction of the image displayed on the display unit is instructed to be switched according to the detected angle. When the display unit is controlled so that the direction of the image displayed on the display unit is switched in response to an instruction to switch the image direction, the display unit can be more reliably adapted to the screen rotation. You can switch the orientation of the image.

  The angle of rotation of the display unit is detected, the switching of the orientation of the image displayed on the display unit is instructed according to the detected angle, and the display unit is displayed in response to the instruction to switch the orientation of the image. When the display on the display unit is controlled so as to switch the orientation of the image, the orientation of the image can be switched more reliably according to the rotation of the screen.

  In addition, when the rotation angle of the display unit is detected and the display control unit is instructed to switch the orientation of the image displayed on the display unit according to the detected angle, more reliably, The orientation of the image can be switched according to the rotation of the screen.

  In addition, although it demonstrated that it switched by 20 degree | times or 70 degree | times, 20 degree | times or 70 degree | times is an example, Not only this but the angle used as a reference | standard can be selected arbitrarily.

  Further, the displayed image is not limited to a still image but may be a moving image.

  Although the display panel unit 11 has been described as being composed of an LCD, the display panel unit 11 is not limited thereto, and may be displayed by other methods such as an organic EL (Electro Luminescence) display or a plasma display. When a self-luminous display is provided, the brightness of the display is controlled instead of blinking the backlight 15.

  Further, the aspect ratio of the screen 15 has been described as being 3 to 4, but is not limited thereto, and may be 16 to 9 or other ratios.
