Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an information processing apparatus having a display means that can arbitrarily change the display direction.

In recent years, the scope of use of this type of information processing apparatus has expanded, and users and usage methods have become more diverse.
However, in general, in this type of device, in a type in which an operating section such as a keyboard and a CRT display are integrally provided, the direction of the CRT display with respect to the operating section is fixed in a constant state. In addition, if the CRT display is configured as a separate unit, the CRT
Changing the direction of the display required lifting it up and changing its direction, which was a time-consuming task. Therefore, it depends on the purpose.
There is a need for a CRT display whose orientation can be arbitrarily and easily changed.

The present invention satisfies these demands and aims to reduce the size of the device, and will be described below along with embodiments thereof.

In FIG. 1, 1 is a main body in which electronic circuits and other devices are housed, 2 is an input section consisting of a keyboard, etc., 3 is a display section using a CRT, and 5 is a display surface. 4 is the lid of the storage section that stores the floppy disk. 6 is a desk portion located on the upper surface of the main body 1, and 7 is a rotary portion that rotatably supports the display portion 3 with respect to the desk portion 6.

In such a device, an operator can easily rotate the display section 3 to direct the display surface 5 in any direction. In this state, the input unit 2 can be operated to input information and perform information processing.

Next, details of the mechanism for changing the direction of the display section 3 described above will be explained with reference to FIGS. 3 and 4. In the figure, a desk part constituting the board has a protrusion 8 for receiving the display part 3. This protrusion 8
A sliding member 9 is added to the surface. Note 1
0 is a fixing screw. On the other hand, a cylindrical side wall 11 is added to the bottom surface of the display section 3 to cover the entire rotation mechanism. A protrusion 12 is provided inside the side wall 11, and a cylindrical portion 13 that fits into the inner peripheral portion of the sliding member 9 is further provided in a part of the protrusion 12.
Discs 14 and 15 shaped like sheet metal are added to the surface of the projection 12. Similarly, the ring 16 also has a protrusion 1.
It is added to 2. The sliding member 9 has an elongated hole shape as shown in FIG. Therefore, display section 3
An annular ring 16 attached to the bottom surface of the member 9 fits inside the member 9, and can be moved in the left-right direction by an elongated hole size S inside the member 9, as shown in FIG. Note that the position of the side wall during movement is 11'. Further, during movement, the disc 15 and the member 9 slide. The signal lines etc. of the display section 3 are connected through the holes 17 and 18.
Can be connected to the main body of the device.

Additionally, gear teeth are formed around the circumference of the disc 14. Note that this tooth portion is shown at an angle in Fig. 2.
It may be partial, such as within CC. Furthermore, a rack 19 is separately fixed to the desk portion 6.
The teeth of the rack 19 and the disc 14 are engaged with each other. The disk 15 is connected to the disk 1 when the display means moves.
4 is a spacer that comes into direct contact with the sliding member 9 and prevents the member 9 from being scratched by burrs of the teeth or the like. The sheet metal member 20 is a stopper for ensuring engagement between the disc 14 and the rack 19 and preventing them from coming off.

Next, the operation of the above embodiment will be explained. now,
In order to change the direction of the display surface 5 of the display unit 3, the first
When a force is applied to rotate the disk in the direction of figure D, the disk 1
Due to the engagement of the teeth 4 and the rack 19, the disk 1
4 rolls on the rack 19 and is displaced to the right. At the same time, the display section 3 is rotated by an angle θ from the front direction. In other words, the direction of the display unit 3 rotates by θ, and the center of rotation moves by S. Therefore, the left end of the display section 3 is kept at an approximately constant position due to the amount by which the portion that houses the floppy disk protrudes toward the lid 4 as it rotates and the amount by which the center of rotation moves in the opposite direction. is maintained. Therefore, there is no risk of the left end protruding toward the lid 4 as the display section 3 rotates, which would impede the opening and closing of the lid 4, unlike when the display section 3 is simply rotated around a single fixed axis. . This state continues until the rotation angle θ is reached. The relationship between θ and the movement amount S of the center of rotation is disk 1
It is determined by the pitch circle diameter of 4.

In this embodiment, the pitch circle diameter of the gear, the rotation angle, Mutual positional relationship, disk 1 on the display section
Conditions such as the position of No. 4 are appropriately set. The range in which the disc 14 can roll on the rack 19 is determined by the inner circumference of the sliding member 9 fixed to the desk portion 6. When the display unit 3 rotates by θ and the center of rotation is displaced by S, the ring 16 comes into contact with the inner wall at the right end of the member 9 and cannot be displaced any further. The allowable rotation angle of the display unit 3 depends on the shape of the inner fitting part of the member 9 (the fitting part with the ring 16),
Determined by dimensions.

In another embodiment, as shown in FIG. 5, the combination of the disc 14 and the rack 19 can be changed to a combination of gears 31 and 32, and the stopper 30 can be made curved. Furthermore, as shown in FIG.
If 3 is composed of a roller, a belt, etc., it can be brought into rolling contact with the gear without sliding, and the rotation of the display section can be made smooth.

As is clear from the above embodiments, according to the present invention, even when the display section is rotated, the center of rotation moves, and the position of one end hardly changes. Therefore, the entire device can be downsized without causing any trouble in opening and closing the lid of the floppy disk or the like. At the same time, the installation space of the device can be reduced, and the space can be used effectively.
