Abstract

(57) [Summary] [Purpose] To provide a notebook-sized compact electronic computer with good operability and easy-to-see display screen. [Structure] The present invention is a notebook-sized small-sized computer having good operability and an easy-to-see display screen, which is pivotally supported at least on the back plate and the back plate having a torque of a specified value or more. (EN) Provided is an opening / closing mechanism for a small computer including a lower cover and an upper cover which is rotatably supported with a torque smaller than that of the lower cover and has a display portion on its inner surface.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an opening / closing mechanism of an improved small-sized electronic computer of a type in which an upper cover having a display section is opened / closed.

[0002]

[Prior art and its problems]

 The opening / closing mechanism of the conventional notebook type small electronic computer has been of a type that opens from the closed state so as to be flat on the table (for example, JP-A-2-259865). On the other hand, the opening / closing mechanism of the upper cover provided with the display portion of the portable office automation equipment is generally arranged in the main body by a support shaft provided with a friction mechanism or a click mechanism. When these conventional techniques are applied to the opening / closing mechanism of a notebook-sized compact electronic computer, there are problems that the display screen is difficult to see or the opening / closing operation of the top cover is difficult.

[0003]

[Means for Solving the Problems]

 The present invention solves these problems, and is a notebook type small computer with good operability and easy-to-see display screen. It has at least a back plate and a shaft support that has a torque higher than a specified value with the back plate. (EN) An opening / closing mechanism for a small electronic computer, which includes a lower cover and an upper cover that is pivotally supported with a torque smaller than the torque of the lower cover and has a display unit on the inner surface.

[0004]

[Action]

 According to the configuration of the present invention, when the upper cover having the display unit is opened, the upper cover first opens to the upper position, and the operation is performed at that position. The cover is in the horizontal position and can be operated even in this state.

[0005]

Embodiments of the present invention will be described below with reference to the drawings. 1 to 3 show an embodiment of the present invention, FIG. 1 is a schematic view of a state in which an upper cover is opened upward, FIG. 2 is a schematic view of a state in which a keyboard is removed, and FIG. Is a schematic diagram of In FIG. 1, 1 is a lower cover, 2 is an upper cover, 3 is a back plate, 4 is a binder provided on the back plate 3, and 5 is a keyboard bound to the binder 4. In FIG. 2, the same members as those in FIG. 1 are designated by the same reference numerals, and 13 is a lower shaft support portion of the lower cover 1 and the back plate 3, which rotates with a torque equal to or more than a specified value. , 23 are upper shaft support parts of the upper cover 2 and the back plate 3, and rotate with a smaller torque than the lower shaft support part 13.

Next, the operation of this embodiment will be described with reference to FIG. First, when the upper cover 2 is closed and the upper cover is lifted, the lower shaft support 13 does not rotate, but only the upper shaft support 23 rotates to move the upper cover as shown in FIG. Is opened upward, and while watching the display screen provided on the upper cover, operate the computer 5 by operating the keyboard 5 on the lower cover (not shown), and further open the upper cover 2 to open the upper shaft this time. Since the supporting portion 23 does not rotate any further, the lower shaft supporting portion 13 rotates to open the upper cover so as to be substantially horizontal on the desk as shown in FIG.

[0007]

[Effect of the device]

 As described above, according to the mechanism of the present invention, operability is good such that the keyboard bound to the back plate does not move even if the angle of the upper cover is changed near the upper side.
