Abstract

PURPOSE:To tilt a display part at an angle where an operator easily look at the display part by turning this display part round a biaxial rotary shaft. CONSTITUTION:The ideal angle conversion is attained by increasing the angles toward a position 7-A from a position 7-S so that an easy-to-see angle without changing a fixed eye position, i.e., the posture and also shifting a display part 7. In other words, a single end of an arm 15 is defined as a fixed rotational center 20 with the other end of the arm 15 set at a lower part and defined as mobile rotational center 21 respectively. Thus a display part tilting means 200 is obtained. While a mobile guide means 100 is obtained by setting the lower edge of the display part along the upper surface of a casing for a display device. In such a constitution, the part 7 has an ideal movement toward position 7-B and 7-A from the initial position 7-S.

Description

[Detailed description of the invention]

[Industrial Application Field] The present invention relates to a display device for electronic equipment, and particularly to an electronic equipment display device including a liquid crystal. [Prior Art] Japanese word processors, which have become rapidly popular in recent years, are increasingly using liquid crystals as one display device, especially in portable types, in order to make the products lighter and smaller. However, due to the physical characteristics of liquid crystal, there is a limit to the angle at which display contents can be easily seen, that is, the viewing angle. Therefore, a method has been adopted in which the operator changes the posture and angle of the display surface by rotating the device around one axis. [Problems to be Solved by the Invention] In general, operators of such electronic devices have different postures that make it easier for them to operate the devices. Therefore, when the user wants to change the angle of the display device due to illumination or the like, if the user also has to change his or her posture due to the angle change, the operation becomes painful. On the other hand, in the conventional angle conversion method using one rotation center,
As shown in FIG. 6, the user had to change his or her posture in accordance with the angle change of the display device, which had an inherent element of causing pain. SUMMARY OF THE INVENTION An object of the present invention is to provide an electronic device having an easy-to-handle display device that allows an operator to easily tilt the display portion to an angle that makes it easy for the operator to view the display portion.

[Means to solve the problem]

The above problem lies in the fact that the display section 7 of an electronic device having the display section 7 and the keyboard 6 on the upper surface is such that the lower edge of the keypad holder 7 moves in the opposite direction of the keyboard 6 along a predetermined trajectory. means 100 for guiding, and the movement guiding means 1
Means 200 for tilting the display section 7 by moving the upper edge upward in accordance with the distance that the lower edge moves by 00;
It is solved by [Operation] As the display unit rotates around two rotation axes, the combined rotation center becomes the operator side space. The display section is tilted to an angle that is easy for the operator to see. [Embodiment] An embodiment of the present invention will be described below with reference to FIGS. 1 to 4. FIG. 2 is an external view of a word processor embodying the present invention. This word processor has its main components held by a lower case 1 and an upper case 2. Upper case 2
A key button 8 and the like are provided on the front edge inclined portion 3. FIG. 1 is a sectional view taken along line I-1 in 2m. The display section 7 has a lower bearing 17 provided on the upper case 2 and an upper bearing 19 provided on the display section 7, each connected by a shaft pin 16.18. By means of the connecting arm 15, position 7 shown in solid line
It has a structure that allows it to move from -5 to 1!7-A, which is indicated by the dotted line. The 3rd @ is a cross-sectional view of FIG. A lower bearing 17.17' is provided at the position of the upper case 2 corresponding to 19°19', and an upper shaft pin 18.18' is provided at the upper end between the two bearings to fit with the upper bearing 19.19'. , lower bearing 17.
The two arms 15.15', which are rotatably attached to the upper case 2, are connected by the connecting rib 14 by the arm 15.15', which has a lower shaft pin 16.16' at its lower end that engages with the lower shaft pin 17'. A gear-shaped engagement tooth portion 13 is provided approximately at the center of the connecting rib 14 . FIG. 4 is an enlarged view of the gear-shaped engaging tooth portion 13. An engaging rib 12 provided on the bottom Jll of the upper case 2 engages with the tooth groove, and is engaged and locked each time the arm 15.degree. 15' rotates by a certain angle. At this time, connecting rib 1
4 is at the level shown by the dashed line in Figure 3 due to its own elasticity! ! 14' and the angle of the arm 15.15' also changes. The angle of inclination of the display section 7 can be freely selected by changing the number of teeth of this gear-shaped engagement tooth section 13. On the main flow side, the lower edge of the 1 display moves to the opposite side of the keyboard guided by the movement guide means 100 configured as a slope of the central slope 4 of the upper case 2, and the upper edge of the 1 display moves to the opposite side of the keyboard. The lower edge of one display can be moved by a display tilting means 200 comprising an arm 15 mechanism that connects a bearing 19 provided at the bottom and a bearing 17 provided in the upper case 2 on the side opposite to the keyboard 6 from the bearing 19. Accordingly, the display section 7 moves upward, tilting and moving away from the keyboard, until it becomes at an angle that is easy for the operator to see. Next, the relationship between the rotation and movement of the display section 7 and the operator will be explained with reference to FIGS. 5 to 10. In general, the liquid crystal display section 7 has an angle that is easy for the operator to view, that is, a viewing angle .theta. in FIG. 5 due to its optical characteristics. This viewing angle θ changes not only due to the positional relationship but also due to lighting and the like. Therefore, the operator needs to adjust the angle when using the product. Conventionally, for this reason, the display section 7 was rotated around a single center of rotation, as shown in FIG. For this reason, as is clear from the figure, the operator has to change the position or posture of his or her eyes as the angle changes, causing fatigue and the like. Here, what should be the ideal angle transformation?
As shown in the figure, it is possible to set the fixed position of the eyes at an angle that is easy to see without changing the posture. As the angle increases from the position -8 to the position 7-A, the display section 7 also moves. In order to achieve this, the present invention provides an arm 15 as shown in FIG.
One end is provided as a fixed rotation center 20, and the other end is provided at the bottom of the display section 7 as a movable rotation center 21 along the top surface of the front casing to serve as a movement guide means 100.
In this example, the initial position 1!7-8 is changed to 7-B and 7-A so that the operation is close to the ideal operation. Further, as shown in FIG. 9, this operation is performed by moving the guide bar 22.24 provided in the display section 7 into the guide groove 23.24 provided in the side wall 9.
This can also be achieved by sliding 25. in this case,
The guide bar 22 and the guide groove 23 constitute a movement guide means 100, and the guide bar 25 and the guide groove 24 constitute a display tilting means 20 (l).Furthermore, as shown in FIG.
7°30, fixed rotation center 26, 29. Moving rotation center 28
．． Even in the multi-point rotation center system consisting of 31? A similar operation is obtained from -8 to 7-B' and 7-A'. In this case, as the movement guide means 100. As in the embodiment, a sloped surface on the upper surface of the casing of the present device may be used as the display section tilting means 200. This applies to the double arm 27 and 28 mechanisms mentioned above. What is common in all cases is that the composite rotation center of one display section 7 is always located above the display section 7, and as a result, an operation close to the ideal shown in FIG. 8 can be obtained. [Effects of the Invention] According to the present invention, since one display section rotates around two rotation axes, one combined rotation center becomes the space on the operator side, and the display section is tilted at an angle that is easy for the operator to see. This has the effect of reducing operator fatigue and making it easier to operate. moreover,
As the inclination angle of the display section increases, it moves away from the operator, so there is also the advantage that no oppressive feeling is caused by increasing the angle.
