Further, when the entire display unit 11 is wound up, a release button is provided, and by operating the release button, the linkage with the feeding mechanism is released to make the winding shaft 14 free, and the winding shaft 14 is The display unit 11 may be entirely rewound by urging in the rewind direction by a spring and utilizing the urging of the spring.

  As shown in FIG. 2, the display device 10 includes an attitude detection unit 25, a drawer length detection unit 26, a RAM 28, a ROM 29, a power supply controller 30, a battery 31, an IF driver 32, an operation unit 17, a display driver 34, a display unit 11, The card controller 35, the card slot 36, the USB controller 37, the USB connector 38, the wireless transmission / reception unit 39, the wireless driver 40, and a CPU 41 that comprehensively controls them are configured. These are built in the storage unit 12.

  The wireless driver 40 acquires content from the content server 43 via the access point 42 that is wirelessly connected to the wireless transmission / reception unit 39. The card controller 35 acquires content from the card memory 46 set in the card slot 36. The USB controller 37 acquires content from an external storage device 47 such as a PC (personal computer) or a digital camera connected to the USB connector 38. The RAM 28 stores content data. The ROM 29 stores a display control program and the like. The power supply controller 30 supplies the power of the battery 31 to each unit in response to the ON operation of the power button 20, and cuts off the power supply in response to the OFF operation.

  The attitude detection unit 25 is a sensor that detects the attitude of the display device 10, and detects the orientation of the display surface 13 in four orientations using a sensor that includes, for example, an acceleration sensor and a gyro sensor. The orientations in the four directions are as follows: the end 16 is drawn upward from the storage unit 12 with the display surface 13 facing forward, the upper vertical is drawn downward, the left horizontal is drawn left, and the right horizontal is drawn right. There are four postures.

  The drawer length detection unit 26 includes an encoder including a nip roller that nips both ends of the display unit 11 inside the storage unit 12 and a pulse sensor that detects a rotation angle of the nip roller. Alternatively, the winding length is detected. The drawer length detection unit 26 detects the length of the bent portion and the flat portion by stacking, for example, ribbon-shaped curvature sensors in the longitudinal direction of the display surface 13 instead of the encoder. It is good also as composition to do.

  The display driver 34 has a VRAM and drives the display unit 11 to display content data once stored in the VRAM. Content data is transferred from the RAM 28 to the VRAM via the CPU 41. The CPU 41 has an image processing unit 45. The image processing unit 45 performs image processing of the content data so that initial display, additional display, and scroll display determined according to information on the amount of withdrawal and the orientation of the display device 10 at that time.

The battery 31 and the electric board constituting each part are preferably arranged in a space that does not hinder the rotation of the take-up shaft 14 inside the storage part 12. Moreover, when using organic EL as the display part 11, you may arrange | position driver circuits, such as organic TFT which has flexibility, between the display surface 13 and the edge of the width direction.
Furthermore, it is possible to improve the portability and the storage property by separating the electric substrate and the display unit 11 from the storage unit 12 and connecting them to each other by wire or wirelessly.

The operation of the above configuration will be described. In the following description, the display device 10 displays electronic content such as books, magazines, and newspapers.
The content data is acquired in the RAM 28 by reading from the card memory 46 or the external storage device 47 or by receiving it manually or automatically from the content server 43 using the wireless transmission / reception unit 39. This is done even when the power is off.

When the user displays and reads a specific page of content, the power button 20 is turned on as shown in FIG. 3 (S-1). Thereafter, the CPU 41 monitors the drawer length detection unit 26 and the posture detection unit 25 (S-2).
The user pinches the end portion 16 and pulls the display unit 11 from the entrance / exit 21 in one direction. This drawer operation is detected by the CPU 41 based on information obtained from the drawer length detector 26 (S-3). Thereby, the CPU 41 is configured to display the image based on the information obtained from the drawer length detection unit 26 and the posture detection unit 25 (S-4) so that the content is displayed as follows based on the detected posture. The processing unit 45 is controlled to display the content on the display surface 13.

  When it is detected as a vertically long posture ("Y" side in S-5), as shown in FIG. 4, the display unit 13 is facing forward and the end 16 is pulled upward with respect to the storage unit 12. Therefore, the left corner of the drawer start end 15 is set as the display start position 50, and the display origin (coordinate origin) is set at this position to display the content 51 (S-6).

  When it is detected as a vertically long posture (“Y” side in S-7), as shown in FIG. The position shifted from the left corner 52 by the length of the drawer is set as the display start position 53, and the content 54 is displayed with the display origin set at this position (S-8).

  When the left side orientation is detected ("Y" side of S-9), the end 16 is pulled out to the left with respect to the storage unit 12 as shown in FIG. The upper corner is set as the display start position 55, and the display origin is set at this position to display the content 56 (S-10).

  When it is detected that the posture is right sideways ("N" side of S-9), the end 16 is pulled out to the right with respect to the storage portion 12 as shown in FIG. The position shifted from the upper corner 57 to the left by the length of the display is set as a display start position 58, and the content 59 is displayed with the display origin set at this position (S-11).

  Here, the display on the display surface 13 is performed on the drawn region, that is, the region exposed to the outside from the storage unit 12, and the wound region, that is, the region stored in the storage unit 12. Is hidden. Thereby, the processing load and power consumption in the CPU 41 and the image processing unit 45 can be suppressed.

  The display operation procedure described above describes the display process when the user starts to pull out the display unit 11. Thereafter, when reading the subsequent content, an operation of further pulling out the display unit 11 is performed. As shown in FIG. 8, the CPU 41 monitors the drawer length detection unit 26 and the posture detection unit 25 (S-12), and further pulls out the display unit 11 based on information obtained from the drawer length detection unit 26. Is determined (“Y” side of S-13), based on the posture information obtained from the posture detection unit 25 at that time, an image processing unit is arranged so that a page to be additionally displayed is laid out as follows. 45 is controlled and displayed on the display unit 11. “Initial drawer length” shown in FIG. 6 indicates the length of the display unit 11 that is first pulled out, and “additional drawer length” indicates the length that is pulled out next.

  When it is detected that the posture is vertically long ([Y] side in S-15), the lower side of the initial display content 60 is set as the next display area 61 as shown in FIG. That is, the display of the additional content 62 is added to the newly drawn part (S-16).

  When it is detected as a vertically long posture ([Y] side in S-17), as shown in FIG. 10, the initial display content 64 moves (scrolls) to the additionally drawn region 63, and the lower side is the next. And the additional content 66 is displayed in the next display area 65 (S-18).

  When the left side orientation is detected ("Y" side in S-19), the next display area 68 is set on the right side of the initial display content 67 as shown in FIG. 69 is displayed (S-20).

  When it is detected that the posture is horizontally long (“N” side of S-19), as shown in FIG. 12, the initial display content 71 moves (scrolls) to the additionally drawn region 70, and the next display is on the right side of the next display content 71. A display area is set, and the additional content 73 is displayed in the next display area 72 (S-21).

  As described above, the content is continuously displayed every time an operation for further pulling out the display unit 11 is performed. To further add display content of the content with the display unit 11 fully pulled out, the operation unit 17 is used. This can be done by operating the “forward” button 18.

  Further, as shown in FIG. 13, the CPU 41 monitors the drawer length detection unit 26 and the posture detection unit 25 (S-22), and winds the display unit 11 based on information obtained from the drawer length detection unit 26. When an operation to be taken is detected (“Y” side of S-23), the CPU 41 performs the following display control according to the attitude of the display device 10 at that time.

  When it is detected that the posture is vertically long (“Y” side in S-25), as shown in FIG. 14, the displayed contents 75 and 76 are wound in response to the winding operation 74 of the display unit 11. The content 78 displayed so as to move up (scroll out) by the amount of the take-up length and displayed in the wound area 77 is hidden (S-26).

  When it is detected as a vertically long posture (“Y” side of S-27), the displayed contents 80 and 81 are displayed regardless of the winding operation 79 of the display unit 11 as shown in FIG. The content 83 displayed in the wound area 82 is not displayed without being moved and displayed with respect to the section 11 (S-28).

  When it is detected that the posture is horizontally long (“Y” side of S-29), the displayed contents 85 and 86 are wound in response to the winding operation 84 of the display unit 11 as shown in FIG. The content 88 displayed to move to the left (scroll out) according to the take-up length and displayed in the wound area 87 is hidden (S-30).

  When it is detected that the posture is horizontally long (“N” side of S-29), the displayed page images 90 and 91 are displayed on the display unit regardless of the winding operation 89 of the display unit 11 as shown in FIG. 11, the page image 93 displayed in the wound area 92 is not displayed (S-31).

  Thereafter, when the CPU 41 detects an operation of pulling out the display unit 11 again based on information from the drawer length detection unit 26, the CPU 41 returns to the operation of "S-12" described with reference to FIG. 8 and described with reference to FIGS. The procedure is to repeat the display control. That is, from the state in which the display unit 11 is displaying the content 75 (FIG. 18A), the winding operation is performed on the display unit 11 (FIG. 18B), and the drawing operation is performed (FIG. 18C). In response to alternately performing the above, control is performed so that the content 75 being displayed is sent in the forward direction (drawing direction), and the new content 76 is sent in the same direction. At this time, if it is a partial drawing or winding operation, one page unit can be used, and if all the drawing or winding operations of the display unit 11 are performed, a plurality of pages can be sent to send a plurality of pages all at once. . This makes it possible to display information flexibly according to the type of content and the viewing / viewing style of the user. The operation of returning the content to the previous display can be performed by operating a “return” button 19 provided on the operation unit 17.

  In this manner, since the subsequent content is displayed even with a slight winding without pulling out the entire display unit 11, it is possible to view and appreciate the content even when the display unit 11 is slightly pulled out. For example, the convenience of the user can be improved in a small place or in a situation where the user wants to use the content immediately.

  In the above-described embodiment, as described with reference to FIG. 18, control is performed so that page advance is performed by performing a winding operation and a drawing operation, but conversely, FIG. 19A to FIG. As shown in C), in response to alternately performing the winding operation and the drawing operation, the content 75 being displayed is sent in the reverse direction (winding direction), and instead, the content 94 that is the previous page is displayed. Control may be performed so that the page is reversely displayed when is returned.

In each of the above-described embodiments, the belt-shaped display unit 11 is wound and stored in the storage unit 12. However, the present invention is not limited to this, and the sheet-like display unit 11 is not wound around the storage unit 12. It is good also as a structure accommodated so that it can be drawn out freely in a shape.
In each of the above embodiments, one side of the display unit 11 is used as the display surface 13, but display surfaces may be provided on both surfaces. In this case, the operation may be performed with the desired surface facing forward.

  In each of the above embodiments, the display unit 11 and the winding shaft 14 are described as being locked. However, the display unit 11 and the winding shaft 14 are detachably attached, and the longitudinal direction of the display unit 11 Any one of the two ends may be attached to the winding shaft 14. In this case, it is possible to wind up the display surface on either surface. It is possible to attach to the take-up shaft 14 at the user's discretion whether the take-up start / end is selected. Moreover, you may wind by making the display surface 13 into the outer side.

  Further, in the embodiment in which the display unit 11 and the winding shaft 14 are detachably provided, it is necessary to provide a drawer start end detection unit that detects the drawer start end 15. The drawer start end is the end of the display unit 11 that is the end of the winding, that is, the boundary between the display unit 11 and the entrance / exit 21 when the display unit 11 is pulled out. For example, when an illuminance sensor is used as the drawer start end detection unit, a configuration in which the bright side is the drawer start end, and when a pressure-sensitive sensor or a capacitance sensor is used, the user's hand holding the end 16 is used. And a configuration for detecting a finger.

  In each of the above embodiments, the “forward” button 18 and the “return” button 19 are provided on the operation unit 17, but instead of being provided on the operation unit 17, they may be provided in an area outside the display surface 13. Moreover, it is good also as a structure displayed on the display surface 13. FIG. In this case, a flexible touch panel may be provided on the display surface 13. And it may be configured to execute in response to detecting a specific operation (gesture operation), for example, “finger swipe (swipe)” using the touch panel. Furthermore, an area to which functions such as “feed” and “return” are allocated and an icon may be provided.

  In each of the above embodiments, the four postures determined by the CPU 41 based on the information obtained from the posture detection unit 25 are determined with reference to postures read by the user (user) with the head up. However, for example, when the user operates the display device 10 in the posture of lying down with the right side down, the CPU 41 determines that the posture is the right sideways or left sideways orientation, whereas the user is upside down or Since a display layout with a vertically long posture is desired, the display becomes difficult to see.

  Therefore, a camera unit for photographing the user's face and a face posture detection unit that detects the posture of the user's face based on a face image obtained from the camera unit are provided, and the detected face posture, for example, a normal vertical posture The four postures detected by the posture detection unit 25 may be converted based on the postures such as lower right sleep, lower left sleep, and reverse sleep. For example, when it is determined that the user is lying on the right based on the information obtained from the face posture detection unit, the “right horizontally long” posture determined from the information obtained from the posture detection unit 25 is converted into the “upper vertically long” posture. For example, even when the user is lying down, the content layout can be displayed based on the sleeping direction.

  Furthermore, when the display device 10 is rotated while the display unit 11 is pulled out and content is displayed, the display layout may be changed based on the newly changed orientation of the display device 10. Further, even if the newly changed orientation of the display device 10 is changed, the display layout may be maintained as long as the content displayed when the initial orientation is detected is still displayed.

  In the present embodiment, since the display device can be vertically and horizontally positioned and the drawer start end may be either end of the display unit, the content has a horizontal aspect of 1 as shown in FIGS. : 1 square block is stored as a unit page 95. However, it is needless to say that a general letter size aspect can be dealt with by enlarging or reducing the display device 10 in the displayable range in accordance with the vertical or horizontal position.
