Abstract

PURPOSE:To realize scrolling and paging operations by a single operating device, by using an operating dial provided with functions to detect both an angle of rotation and a position of depression. CONSTITUTION:The main body 3 of a remote-control unit is provided with an operating dial 1 and other operating buttons 2. The operating dial 1 controls scrolling with its rotation and paging with its depression. By detection of four directions, including the right and left directions as well as the front and back directions, the depression of the operating dial 1 makes it possible to use a turn of a page for instruction of an operation not only in the front and back directions, but also between page blocks such as chapters or paragraphs, making it possible also to give an instruction of changing over the upward and downward directions and the right and left directions with respect to the direction of scrolling by the rotation of the operating dial 1.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a dial device for a screen display device using a cathode ray tube (hereinafter referred to as CRT) or other display element.

Conventional Technology Conventionally, when displaying and searching data stored in Videotex, etc. on a single screen of a 1T monitor, the information is organized in page units, and menus on the screen are selected in sequence as shown in Figure 4. A search method was used to obtain the desired information.

As shown in FIG. 4, menus 12 are presented on the screen of the terminal device 11, and when the user selects one of the menus 12, a page of information corresponding to the menu is displayed. When you select number 1 from the menu 3 out of 12, information page 13 will be displayed. If you select number 2, the next menu 14 will be presented, and if you specify this Sony number 1491, information page 15 will be displayed.
However, when number 2 is specified, another many page 16 is presented and the same process is repeated. When number 3 on menu 12 is specified, information page 17 is displayed.

Problems to be Solved by the Invention In the above configuration, the operation functions are limited to page-by-page operations such as page turning and page return.

Therefore, it is inconvenient when it is necessary to refer to two consecutive screens spanning several pages in the screen configuration before and after the page seam. For this reason, it is necessary to scroll line by line instead of switching page by page.

To perform this scrolling, a scrolling method has been implemented in which the display screen of a personal computer is rotated using a rotating dial, but it is not possible to switch page by page, which is effective for viewing the entire page at high speed.

The present invention is intended to solve these problems, and aims to provide a single operating device that satisfies both screen switching and line-by-line scrolling.

Means for Solving the Problems The present invention provides means for realizing scrolling and page turning operations with a single operating device by using an operating dial that has the function of detecting both the rotation angle and the pressed position. This is what we provide.

Operation In the above configuration, the scroll function and its speed are adjusted by adjusting the rotation angle of the operation dial, and the page turning function is controlled by pressing down on the operation dial. In this case, the direction of page switching can be adjusted depending on the direction of depression.

EXAMPLES Hereinafter, specific examples of the present invention will be described with reference to the drawings.

FIG. 1 is an external view of a remote control device equipped with an operation dial according to the present invention. In the figure, 1 is the operation dial;
Reference numeral 2 indicates other operation buttons, and reference numeral 3 indicates the main body of the remote control device. The operation dial 1 controls scrolling by rotating it, and page turning by pressing it down. The situation is shown in FIGS. 2 and 3.

FIG. 2 is an external view of the parts for the operation dial 1. A disk 5 for detecting the rotation angle is connected to the operation dial 1 by a rotating shaft 4, and when the operation dial 1 is turned, the disk 5 rotates. The amount of rotation can be detected by the rotation angle detection mechanism, and thereby the amount of scrolling can be controlled.

FIG. 3 is a cross-sectional view of the operation dial 1, which is connected to the rotating shaft 4 through a joint 6 so that the surface of the operation dial can be pushed down in the front-rear direction. When the operating surface of the dial 1 is pressed down, a switch 7 provided on the main body 3 of the remote control device is turned on, and a page turning function can be generated. At this time, the joint 6 may not be provided, and the displacement caused by pressing down may be absorbed as a deflection of the operation dial 1 or the rotating shaft 4. That is, page turning is controlled based on the presence or absence of deviation of the dial surface or rotation axis from the reference position, which is caused by pressing down on the dial surface.

By detecting the direction in which the operation dial 1 is pressed down, the four directions including left and right, as well as the front and back, can be used to switch pages not only forward and backward, but also for operation instructions between page blocks such as chapters and sections, and by rotating the operation dial 1. It is also possible to instruct the scrolling direction to be switched between up and down and left and right.

In addition, the detection method of the push-down direction is more effective than strict measurement.
Since it is only necessary to be able to discriminate between the directions, a method of detecting contact between the operation surface of the operation dial 1 and the surface of the remote control device main body 30 may be used.

In the above embodiment, the operation dial or moco 7 is
Although the case where it is provided in a non-device has been described, it may be provided in the display device itself.

In addition, the operation dial may be lever-shaped instead of disc-shaped. Further, when the operation dial is opened, the rotation angle and the inclination of the operation surface can be automatically returned to the reference position by a well-known mechanism using a suffling or the like.

Effects of the Invention As described above, the present invention enables not only switching between the lid and the page but also the screen using a single operating device in the operation dial of Videotex, etc., which conventionally could only switch between pages and had problems with the operability of information display. This provides a means to enable continuous scrolling of information, and has great industrial effects from the viewpoint of improving the operability of information search functions.
