BACKGROUND OF THE INVENTION At present, there are no known information devices equipped with a rotary table as described above. FIG. 5 shows a conventional structure including only a rotary table, and FIG. 6 is a sectional view of the conventional structure.

In the structure shown in FIG. 5, a rotating plate member 51 is placed on a ring-shaped rail 53 provided on a base member 52.
As shown in the figure, they come into contact and slide and rotate. The rotating plate member 5
1 is supported at its center of rotation by a boss 54 protruding from a base member 52 by a screw 55 or the like. The ring-shaped rail 53 is generally made of highly lubricating resin, or a lubricant such as grease is used between it and the rotary plate member 51.

[Problems to be Solved by the Invention] In the case of conventional information equipment, particularly information equipment such as book type (laptop) computers equipped with a display, a liquid crystal display is generally used as the display device. is widely known. Compared to cathode ray tubes, LCD displays have a narrower angle range for good visibility, and the user must be positioned directly in front of the LCD display to see the displayed content well. . Therefore, when a user wants to change the direction of use of the computer, he or she has to lift the computer and change its orientation. In addition, if multiple people are viewing the same screen, the computer must be lifted and rotated to an angle that is convenient for each user, or the users themselves must move the computer while using it. Ta.

On the other hand, in the conventional structure of the rotary table shown in FIG.
Since the rotating plate member 51 slides and rotates on the ring-shaped rail 53 provided on the base member 52, its rotatability is influenced by the friction state between the rotating plate member 51 and the ring-shaped rail 53. As the weight of the object increases, the frictional force increases and the rotation becomes less smooth.

[0006]Furthermore, the rotating table installed in information equipment should rotate as necessary and should not rotate easily, but it must rely on a very unstable force called frictional force to generate the force that controls the rotation. Because of this, it is difficult to control the quality of the rotational force of the turntable at a constant level.

[0007] The present invention has been made in consideration of these circumstances, and its purpose is to enable smooth rotation of the rotary table, generate a click motion for rotation and stop, and to An object of the present invention is to provide an information device having a rotary table capable of accurately controlling a predetermined force.

[0008]

[Means for Solving the Problems] The present invention has a rotary table that is integrally formed with or detachably arranged on the bottom surface of an information device, and the rotary table is formed integrally with the bottom surface of the information device or rotates independently. It includes a dish member and a base member, a holding member inserted between the rotating dish member and the base member holds a cylindrical shaft or a ball, and the rotating dish member holds the cylindrical shaft or the ball. or in contact with the ball, the rotating plate member rotates in the circumferential direction in cooperation with the rolling of the cylindrical shaft or the ball, and the holding member rotates in the rolling direction of the cylindrical shaft or the ball. The click mechanism member is characterized in that it is held while rotating without interfering with the rolling thereof, and further includes a click mechanism member for generating a click motion between the rotating plate member and the base member when the rotating plate member rotates. A step-shaped member is arranged between the rotary plate member and the base member.

[0009]

[Operation] In the above configuration, by installing the rotary table on the bottom of the information device, it is possible to rotate and move the information device without lifting it.
As the ball rotates, the rotary table rotates smoothly, and also rotates while generating a click motion, and can control rotation and stopping using a predetermined force.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be specifically explained below with reference to illustrated embodiments.

FIGS. 1, 2, 3 and 4 show embodiments in which the present invention is applied to a book (laptop) type personal computer, in which a turntable 13 is arranged on the bottom surface 12 of the book type personal computer 11. has been done.

The rotating plate member 21 of the rotating table 13 is formed integrally with the bottom surface 12 of the book type personal computer 11, but in the drawings after FIG. Component 21 is shown as an independent model. A cylindrical shaft 24 held by a holding member 23 is disposed between the rotary plate member and the base member.
is inserted. (See FIGS. 2 and 3) The holding member 23 is rotatable with the center hole 27 being regulated by a basically cylindrical support boss 31 formed on the rotating plate member 21. As shown in FIG. 3, the cylindrical shaft 24 is supported near the center by the holding member 23, and the shaft insertion hole 28 and the cylindrical shaft 24 are maintained at a distance that does not interfere with rotational movement. Since the shaft diameter of the cylindrical shaft 24 can be arbitrarily changed, it is possible to make the rotating table 13 thin by setting the shaft diameter small. Further, the length of the cylindrical shaft 24 can be set arbitrarily, but if the shaft length is made too long, a large difference in rotation will occur between the rotating part near the center position of the turntable and the rotating part far away, and smooth rotation will not be achieved. In that case, you may be afraid of
It is necessary to change the shaft shape to a truncated cone shape as appropriate. Furthermore, the number and position of the cylindrical shafts 24 can be set arbitrarily, but due to the influence of the rotation difference mentioned above, the positions and shaft diameters should be adjusted as appropriate to obtain smooth rotation. . Further, the same effect can be obtained by replacing the cylindrical shaft 24 with a spherical member. Also, the rotating plate member 2
1 and the base member 22 can be locked with a single touch by a claw 32 formed on an extension of the support boss 31.

The rotating plate member 21, the base member 22, the holding member 23, and the cylindrical shaft 24 are usually preferably made of various plastic materials, but may also be made of aluminum, magnesium alloy, or other various materials. It is possible.

The click mechanism member 25 has a spring and other elastic members built therein, and the click claw 41 is connected to the arrow 43.
It is elastically slidable in the direction of . Further, a step-shaped member 42 is formed inside the rotating plate member side wall 26.
When the rotating plate member 21 is rotated, the click mechanism member 2
The click pawl 5 and the step-shaped member 42 generate a click motion. If the elastic force of the elastic member in the click mechanism member that elastically presses the click claw 41 is set to an arbitrary strength, if a rotational force equal to or greater than the set value is applied to the rotary plate member 21, it will rotate, and if it is less than that, it will rotate. It is possible to hold it in a restrained state. (See Figures 2 and 4). Step-shaped member 42
can be integrally molded with the rotating plate member side wall 26.

Although this embodiment shows an example in which the rotating base 13 is integrally formed on the bottom surface 12 of the book type personal computer 11, the rotating base 13 can also be attached by screws, etc.
It is also possible to configure it so that it can be attached and detached by engaging with a hook. When the rotary table is made detachable, the user can select whether or not to use the rotary table according to his/her preference. By attaching the turntable 13 to the book type personal computer 11, the turntable can be utilized, for example, when the book type computer 11 is taken to a presentation conference on the go and used as an aid for a presentation due to its light weight. This makes it possible to easily show the display section to multiple participants sitting in various positions. Furthermore, even when an instructor and a student use one book-type personal computer 11 next to each other, the computer can be rotated alternately and used comfortably.

Note that the invention is not limited to the above-mentioned embodiments, and various modifications are possible. For example, the click mechanism member is placed on the rotary plate member side, and the step-shaped member 4
2 on the base member side, similar effects can be obtained. In addition, the cylindrical shaft that rolls within the rotary table is shaped like a gear, and the rotating plate member and the base member are also shaped like gears, and the gears are engaged, and a click motion is generated between the gear and the holding member. Even if such a structure is created, the same effect will be achieved.
