Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial field of application) The present invention relates to a small electronic device such as a laptop computer or a word processor, and in particular, its plate-shaped display portion can be opened and closed with respect to the device body. The improvement of the display opening / closing structure for small electronic devices.

(Prior Art) For small electronic devices such as laptop computers and word processors, by integrally forming each device such as a display, a printer, and a floppy disk connected to them, at the same time, it is easy to use. , There are some that enable downsizing of the entire device and portability.

For example, the display unit is incorporated into a plate-shaped display panel, a rotary shaft is provided below the display panel, and a support hole for supporting the rotary shaft is provided on the main body side to provide a rotatable mechanism with a fulcrum. Further, the display panel also serves as a lid on the front of the main body of the device, and when it is stored, the display surface is directed downward toward the front of the device and closed as a lid on the front of the main body, and when used, the display surface is expanded toward the front of the device.

There is also a printer having a print output function by integrally forming a printer on the rear part of the device behind the display panel.

(Problems to be solved by the invention) However, by consolidating each of these devices to form one electronic device, conversely, it is difficult to use.

For example, in the case of a small electronic device in which the printer as described above is configured behind the display panel and the display panel is expanded when the device is used, the display panel is viewed from the operator who sits in front of the device and operates. Since there is a problem that the rear printer is hard to see, it is difficult to see.

In view of such conventional circumstances, the present invention provides a compact electronic device in which at least a display panel and a printer are integrally formed in the above-described structure, from the bottom of the device body to the tip of the display panel when the display panel is opened. It is an object of the invention to provide a small electronic device having a structure in which the height behind the display panel can be easily seen while keeping the height low and the vertical dimension of the display panel itself is not reduced.

[Structure of the Invention] (Means for Solving the Problem) In order to achieve such an object, the plate-shaped front portion is rotated around the lower rotation shaft and the support hole of the main body supporting the rotation shaft as a fulcrum. This is a small electronic device that can be moved freely and closes as a lid on the front of the main unit with the display surface facing down in the front of the device when stored, and is installed at the bottom of the display in a small electronic device that expands with the display surface facing the front of the device when used. A long groove substantially parallel to the display surface, into which the rotary shaft is slidably fitted, and one end fixed to the inside of the display part, and the other end locked to the rotary shaft fitted into the long groove. A spring that pulls the
The spring supports the lower end of the display portion that is pressed against the main body by pulling the rotating shaft by the spring, and pushes the display portion upwards against the spring when the storage portion is housed, and when using, the display portion is moved according to the spring. A small electronic device including a curved surface portion for guiding provided below the supporting hole of the main body, which is dropped downward, was devised.

(Operation) In the case of a small electronic device having such a configuration, by opening a plate-shaped display unit that is closed as a lid at the front of the device body when it is stored, the lower side of this display unit is It becomes possible to dive in and hold the height from the bottom of the main unit to the tip of the display unit low.

That is, the rotating shaft at the lower part of the display is always attracted to the upper part of the display by the spring. Therefore, the lower end of the display portion is always pressed downward (on the main body side) against the main body that holds the rotary shaft by the support hole. A curved guide surface is provided on the main body side against which the lower end of the display portion is pressed, and the display portion moves up and down according to the shallow depth of the curved guide surface.

The guide curved surface is formed so as to be shallow at the position where the display unit is stored and deep at the angle range when used. Therefore, at the time of storage, the display unit is pushed up against the tension of the spring and is closed as a lid that covers the front of the device. On the other hand, during use, the display unit is pushed down toward the lower main body in accordance with the tension of the spring, and the height of the tip of the display unit from the bottom surface of the device decreases.

(Embodiment) FIGS. 1 to 3 are perspective views of a small electronic device according to an embodiment to which the present invention is applied. FIG. 1 is a storage (portable) state in which lids of respective parts are closed, and FIG. Shows the use state with the lid opened, and FIG. 3 shows the state with the lids of these parts removed.

Reference numeral 1 is a main body of a small electronic device such as a laptop computer or a word processor. In this body 1,
For example, a display unit 2 incorporating a display using a liquid crystal device (LCD) or plasma as a plate-shaped display panel.
However, the lower part thereof is rotatably mounted around the center of rotation.

When the display unit 2 is opened, the keyboard 4 arranged below the display unit 2 can be seen, and the display surface 6 of the display unit 2 can also be seen from the front side of the device.

Further, a printer 8 for outputting prints is attached to the rear portion of the main body 1 together with a dedicated lid, and a floppy disk device (FDD) 3 is arranged on the side surface of the main body 1.

FIG. 3 is a view in which the display section 2 and the lid section of the printer 8 are removed, and shows a mounting configuration of the display section 2 to the main body 1.
The rotation shaft 9 which is the rotation center of the display unit 2 and the support hole 10 which rotatably supports the rotation shaft 9 are visible. Rotating shaft 9
Slides in the direction of arrow E in FIG. 3 within the range of the long groove 11 which is an opening provided on the side surface of the display unit 2. That is, the rotating shaft 9 can be displaced with respect to the display unit 2.

Reference numeral 5 is a platen knob for moving the printing paper of the printer 8.

FIG. 4 is a cross-sectional view taken along the line AA of FIG. 3 and shows the mechanism of this one embodiment device. Reference numeral 12 is an exterior cover of the main body 1, and 13 is a base surface of the main body 1, both of which are plastic molding materials.

FIG. 5 is a perspective view showing a cross section of the BB surface of FIG. 3 with the cover of the display surface 6 of the display unit 2 removed. The rotating shaft 9 is a plastic molding material, and by the spring 14,
It is always pulled in the direction of the boss 16 which fixes one end thereof. Further, the display surface 6 is fixed by the screws 17 to the display unit cover 15
Is stuck to.

In FIG. 2, if the H dimension, which is the height from the bottom surface of the main body 1 to the tip of the display unit 2, is too high, the printed portion of the printer 8 at the rear of the main body 1 becomes difficult to see, and the printing cannot be confirmed.

In order to reduce the H dimension, the vertical dimension of the rotating display unit 2 may be reduced.
Since it also serves as a lid, it cannot be smaller than the depth dimension of the keyboard 4. In terms of use, the wider the display surface 6 is, the better the usability is, and for this reason, the vertical dimension of the display unit 2 cannot be reduced.

Further, by lowering the printer 8 further toward the rear of the main body and increasing the inclination of the display unit 2, it is possible to reduce the above H dimension and make the printed portion of the printer 8 easy to see. However, when the printer 8 is lowered, the depth dimension of the main body 1 (second
D) in the figure becomes large, which is incompatible with the miniaturization of the device.

For this reason, in this invention, the H dimension is reduced by the lower portion of the display portion 2 submerging into the device body 1 when the display portion 2 is opened and used.

In FIG. 4, 2a shows the display unit 2 in the closed state, and 2b shows the open state.

A convex portion 19 having a frictional property is projected on the display portion 2, and slides while being pressed against a guide curved surface portion 20 integrally molded with the exterior cover 12 of the main body 1.

That is, the boss 16 protruding from the cover 15 of the display unit 2
The other end of the spring 14 fixed at one end to the rotating shaft 9
Is held by a plate member 22 integrally formed with the display unit 2 by the tension of the spring 14, and the display unit 2 is always pulled in the direction of the rotary shaft 9. Since the rotating shaft 9 is rotatably held in the main body 1 by the support hole 10 provided in the main body 1, the display unit 2 is always attracted to the main body 1 side, and the convex portion 19 at the lower end of the display unit 2 is provided. Will be pressed against the guide curved surface portion 20. The plate member 22 formed integrally with the rotary shaft 9 is provided with the groove 21 formed integrally with the display cover 15.
It is like sliding inside.

In this way, the rotation shaft 9 which is the rotation center of the display unit 2 is displaced in the direction of FIG. 3E with respect to the display unit 2, and the display unit 2 moves up and down according to the shallow depth of the curved surface portion 20 for guiding. . Due to the shallow depth of the curved surface portion 20 for guide, the size of the display portion 2 submerged in the main body 1 (1, 11 in FIG. 4) changes. As shown in FIG. 4, the curved guide surface portion 20 is provided on the display portion 2 as shown in FIG.
It is formed so as to be shallow in a substantially horizontal storage state in which is closed and deep in a use range state in which the display unit 2 is raised.

At this time, the tension of the spring 14 is set so that an appropriate frictional resistance can be obtained between the convex portion 19 at the lower end of the display unit 2 and the curved guide surface portion 20, and the frictional force causes the display unit 2 to move freely. Even if you move it to the angle of, it will be locked at that position.

In this way, the display unit 2 keeps a sufficient length to cover the keyboard 4 in the housed (carrying) state, and in the used state, the lower part thereof sunk into the main body 1 and is indicated by H in FIG.
The size can be pressed down, and the printer 8 behind the display unit 2 can be easily seen. At the same time, the viewing angle between the display surface 6 of the display unit 2 and the keyboard 4 is reduced, and the range of movement of the line of sight is reduced, which reduces fatigue and improves usability.

[Effects of the Invention] As described above, in the case of a small electronic device to which the present invention is applied, the display unit rotatable with respect to the main body has a high height from the rotation axis in a stored (portable) state in which the display unit is closed. Since it becomes low in the opened use state, a device such as a printer at the rear of the device becomes easy to see and operability is improved. Also, since the display surface of the display unit is close to the operation unit such as the keyboard in front of the device,
The range of movement of the line of sight is small, fatigue is reduced, and usability is improved. Further, even if the display unit becomes large, it is not necessary to lengthen the front and rear dimensions of the device main body in order to reduce the height of the display unit, which is effective in downsizing the device.
