Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a portable information processing device, and particularly to a portable information processing device that has a display section with a built-in large display. The present invention relates to an information processing device including a mechanism for stably holding the device.

[Conventional technology]

Conventional information processing devices of this type have been designed to be more compact, e.g., A4 size, and lighter in weight, so that users can easily use them in various locations depending on their intended use. . These information processing devices have become more compact and lightweight, and have become widespread, with the ability to be carried from indoor to indoor, indoor to outdoor, or vice versa.

The structure of this portable information processing device is such that a keyboard for inputting information, a floppy disk drive (hereinafter referred to as FDD) for recording information, and a control board for processing information are housed in the same part. The display section that performs the display is housed in a separate part and can be opened and closed to serve as a cover for the key operation section. Furthermore, the display section is held by a spring hinge structure so that the user can position it at a position that is easy to view.

[Problem to be solved by the invention]

In the above-mentioned conventional technology, in order to make the information processing apparatus smaller and lighter, the opening and closing angles of the display section and the key operation section when operating the information processing apparatus are limited.

The reason for this is that when the display section is opened and closed, the center of gravity of the display section moves, so when the opening and closing angle is increased, the center of gravity of the device itself shifts to the rear, which causes the device to become unstable (sitting) and fall backwards. . Therefore, there are methods such as limiting the opening/closing angle of the display section within a certain range, or increasing the ground contact area on the key operation section side, in other words, on the ground surface side.

However, with regard to the former, there is a problem in that, from the viewpoint of a portable information processing device, the device limits the installation location and environment of the device, as well as the operating posture of the user.

On the other hand, regarding the latter, there have been problems in that portability, which is the original appeal of the device, becomes inconvenient due to the increased size and weight of the device due to the expansion of the ground contact area, and the ease of use becomes increasingly poor.

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned problems and provide a portable information processing device in which the opening/closing angle of the display section can be set to a desired angle by the user without depending on the weight balance of the device.

[Means to solve the problem]

In order to achieve the above purpose, a stabilizing plate is provided near the hinge part that supports the key operation section and display section of the information processing device, that is, at the rear of the information processing device, so that it can be stored inside the device or attached to the underside of the ground surface. .

When the information processing device is installed on a horizontal surface and the display section is opened and closed to the maximum, this stabilizing plate is smaller than the projected area of the display section projected perpendicularly to the horizontal surface, and furthermore, it is smaller in both the stacking direction and the depth direction of the device. Set it in advance so that it is small.

[Effect]

According to the above means, when a user installs and uses an information processing device, the user is able to The opening/closing angle of the display section of the information processing device is set to a desired opening/closing angle according to the above conditions.

At this time, the center of gravity of the key operation section on the ground side does not change, but the center of gravity of the display section changes with respect to the key operation section depending on the opening/closing angle. This means that the center of gravity of the entire information processing device changes. In other words, depending on the opening/closing angle of the display section, the center of gravity of the information processing device shifts to the rear, causing the information processing device to fall backward (turn over).

Therefore, by pulling out the stabilizing plate stored inside the information processing device or under the ground surface of the device and reinstalling the device, it is possible to stabilize the information processing device whose center of gravity has moved later depending on the opening/closing angle of the display section. .

〔Example〕

An embodiment of the present invention will be described below based on the drawings.

The portable information processing device II has a keyboard 13 for inputting information, an FDD 12 for recording information, a control board 14 for processing and controlling information, and a connector 15 for connecting to an external 8-power device during output work. It consists of a key operation section 2 which is located at the rear of the device, and a display section 3 that has a built-in display 16 for displaying information. The display section 3 has a structure that can be opened and closed so as to cover the key operation section 2, and a rotating shaft 17, which is the center of opening and closing, is provided at the rear of the key operation section 2.

Further, a stabilizer plate 4 having a handle shape that can be stored inside the device is provided at the rear of the information processing device 1, so that the user can take it in and out of the device by himself when carrying it around. FIGS. 5 and 6 show the internal structure of the information processing device ll having this stabilizing plate 4.
As shown in the figure.

The stabilizing plate 4 is placed on the bottom case 5, and is clamped from above by an intermediate plate 7 having claws that fit into the sea urchin case 6. This intermediate plate 7 is fixed to a boss 8 provided on the lower case 5 with screws 9.

In addition, the size of the stabilizer 4 shown in FIG. 4 is shorter than the length of the display section 3 in the direction of the mounting depth (length BC in FIG. 4) projected perpendicularly to the ground plane in the model, and the length of the stabilizer 4 shown in FIG. Indicates that it is smaller than the width of .

Further, the shape of the grip of the stabilizing plate 4 is made partially at the same height as the reed 1o provided on the ground surface side of the lower case 5 when the information processing bag H1 is grounded on a horizontal surface.

Further, the lower case 5 is provided with a recess 18 in which the stabilizer plate 4 is hung, in order to facilitate the insertion and removal of the stabilizer plate 4.

In the above configuration, the information processing device 1 provided with the stabilizing plate 4
The operation and effects of this will be explained.

FIG. 4 is a model of the operation and center of gravity position of the information processing device 1, and the size of arrow A is the mass of the information processing device 1. The size of this arrow A is (arrow A) = (arrow B
)+(arrow C) In other words, the mass of the information processing device 1 is the sum of the mass of the key operation section 2 and the mass of the display section 3. Further, in the figure, 1a represents the center of gravity of the information processing apparatus with the display section 3 closed, 2b represents the center of gravity of the key operation section, and 3C represents the center of gravity of the display section.

Here, when opening the display section 3 to the key operation section 2, the center of gravity position 2b of the key operation section 2 and the center of gravity position 3 of the display section 3
c is the center of gravity position 1 of the information processing device 1, although each does not change.
Since a is a combination of the center of gravity position [2b and 3c, the center of gravity position 3c moves when the display section 3 is opened as viewed from the information processing device 11.

This is because when the opening/closing angle of the display section 3 increases (opens), the center of gravity position 1a of the information processing bag fil moves to the rear of the apparatus.

At this time, if the opening/closing angle desired by the user of the display section 3 exceeds a certain angle, the grounding balance of the information processing device 11 will be disrupted, making it unstable, and there is a risk that the display section 3 will turn over in the opening/closing direction, that is, toward the rear of the device. be.

If the information processing device 11 falls backward due to this imbalance, it will cause the following problems.

(1) If the user does not hold down the key operation unit 2 or a part of the device, the information processing bag fill will tend to fall backwards, making it extremely difficult to input information by key operation.

(2) If the device falls backward, there is a risk that parts and cases built into the display section 3 and key operation section 2 may be damaged.

(3) Similar to defect (2), but information processing device 1
External force may act on the external connector 19 connected to the connector 15 provided at the rear of the connector, damaging the connector or the vicinity of the connector.

However, the above-mentioned problem can be solved by pulling out the stabilizing plate 4 provided at the rear of the information processing device 1 from inside the device, which supports the information processing device 1 from falling to the rear due to movement of the center of gravity [1a], thereby stabilizing the device. Therefore, the user can easily obtain the desired opening/closing angle of the display unit 3 so that the device falls backward at a certain angle, and also prevents damage to built-in parts and cases due to falling, and external force applied to the connector part. can be prevented.

Furthermore, as shown in Fig. 4, the size of the stabilizing plate 4 is within the space ABCD formed by the display section 3 and the ground plane, so that the ineffective space that is shadowed on the desk by opening and closing the display section 3 can be used effectively.
There is also the effect of saving space on the desk when the information processing bag is in use.

Furthermore, since the shape of the stabilizer plate 4 has a handle shape,
When the user closes the display unit 3 and carries the information processing device 1, the user hooks his or her finger into the recess 18 provided in the bottom case 5, pulls out the stabilizing plate 4, and holds the handle to easily open the information processing bag R1. It also has the advantage of being portable.

Of course, as is clear from FIGS. 5 and 6, by giving the rear part of the information processing device 1 a more rounded shape than that of the bottom case 5 and the sea urchin case 6, the user can, for example, have a rounded shape even if the user does not use the above-mentioned carrying method. Even if you hold the stabilizer plate 4, it will not get in the way because it can be stored in the key operation unit 2.

Next, other embodiments will be explained with reference to FIGS. 7, 8, and 9.

The rotary stabilizer 24 having a handle shape is attached to the seat case 25.
The rotary shaft 27 is inserted into the rotary hole 26 formed on both the left and right sides of the rotary shaft 27, and the shape of the rotary stabilizer plate 24 keeps it inserted.

In addition, the seat case 25 is provided with a storage part for storing the rotary stabilizer 24 so that it does not protrude from the external shape of the information processing device 1 when stored, and a recess 28 is provided in the center of the groove perpendicular to the groove having the rotation hole 26. will be established. Further, ribs 29 are provided on the vertical wall of the groove.

This rib 29 is used to stabilize the rotary type when the rotary stabilizer 24 is stored in the lower case 25 to prevent the rotary stabilizer 24 from coming off from the lower case 25 when lifting the information processing device 1 or when it is not needed as a handle. This is to hold the plate 24 between the grooves.

In the above configuration, if the center of gravity of the information processing bag f[1 moves backward due to opening and closing of the display section 3 and the balance is lost, the user can move the display section desired by the user by pulling out the rotary stabilizer plate 24. 3 opening/closing angles can be easily obtained.

In addition to the above-mentioned effects, there are the same effects, such as being able to prevent damage to built-in components, cases, and connectors, and making it easier to carry.

Furthermore, as a unique effect of another embodiment, the seat case 25
By rotating and storing the rotary stabilizer plate 24 on the bottom surface, the number of parts can be reduced compared to the above embodiment, and the ease of assembling the information processing device II can be improved, so a cheaper information processing device can be provided. There is also this effect.

〔Effect of the invention〕

As explained above, according to the present invention, by providing the stabilizing plate, it is possible to prevent the information processing device from falling backward due to the movement of the center of gravity of the information processing device due to the opening and closing of the display section. The opening/closing angle of the display unit desired by the user can be easily obtained depending on the installation environment of the device, the user's operating posture, etc.

Furthermore, since the device can be prevented from falling backwards, damage to built-in components, cases, and connectors connected to external devices can be prevented.

Furthermore, since the stabilizer plate is set to a size smaller than the vertical projected area on the desk when the display is opened and closed to its maximum, it is possible to effectively utilize the ineffective space that would be in the shadow when the display is opened and closed, thereby saving space on the desk. It also has the effect of making it possible to create more space.
