Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to an electronic device, and more particularly, the present invention relates to an electronic device, and more particularly, the device is composed of a plurality of parts connected via a rotation mechanism so that the housing can be folded. Regarding electronic equipment.

[Background Art] In recent years, electronic devices such as electronic desktop calculators and electronic learning machines have become significantly smaller and thinner. However, if the device is made too compact or lightweight, it is possible that the operability will deteriorate, so the device should be designed to have a small external size when carried, and a large external size when operated, so that it can be used easily with a relatively large operating surface. , foldable electronic devices have been proposed.

Foldable devices usually have a main part that houses arithmetic circuits, etc., and a peripheral part that houses a solar cell as a power source and a display unit, connected by a hinge, etc., and the device can be rotated around this part. It is designed to perform folding.

Problems to be solved by the invention] On the other hand, as is well known, small devices such as electronic desktop calculators often use LCD (liquid crystal display) units with low power consumption as display devices. LCDs have a characteristic in that viewing angles at which display contents can be easily viewed are limited, and viewing from other angles is difficult. In conventional electronic devices, the installation angle of the display device is often fixed depending on the posture of the operator, so it may not be possible to obtain a convenient viewing angle.

Furthermore, even in devices where the display angle can be changed using the above-mentioned folding structure, the display is often built into the folding section together with other operating sections and the solar cell section, making it convenient for device operation. If the opening angle of the device is set to be convenient for power generation by solar cells as a power source, it may become difficult to visually check the display. On the other hand, if the opening angle is set so that the display can be visually recognized, the solar cells may not be able to generate enough power or the operability may deteriorate.

[Efforts to Solve the Problems] In order to solve the following problems, in the present invention, the mounting is composed of a plurality of parts connected via a rotation mechanism so that the device can be folded. In electronic equipment,
A configuration is adopted in which a display unit for displaying calculation results and operating conditions is foldably connected via a rotation mechanism whose rotation center is aligned with at least the rotation mechanism.

[Sakukawa] According to the above configuration, at least one rotation mechanism that rotates multiple parts of the device and a rotation mechanism whose rotation centers coincide with each other, that is, one rotation mechanism that is almost common, are used to display images. Since the device unit can be freely rotated, it is possible to fully operate the device after satisfying all the operating conditions of the device or the operating conditions of the operator, which are determined according to the operating environment, and improve operability at that time. can be greatly improved.

[Example] Hereinafter, the present invention will be described in detail based on the example shown in the drawings.

1 and 2 are perspective views showing the structure of an electronic device employing the present invention. The electronic device shown here mainly includes a keyboard unit 1 for inputting operations, an arithmetic unit 3 housing an arithmetic circuit and holding a solar cell 5, and a display unit 6 holding a display 7. It consists of two parts.

First, in the keyboard unit 1, the keyboard 2 is configured on the inner side when folded, as in the conventional case. The keyboard 2 is constructed using a flexible printed circuit board or the like, as in the conventional case.

Further, the configuration of the arithmetic unit 3 is shown in FIG.

FIG. 3 is a cross-sectional view of the arithmetic unit 3 portion of FIG. 1 taken along line pp6. The solar cell 5 is fixed in position by a damper 10 made of a material such as urethane rubber that is mounted between the lower case 4 of the calculation unit 3 and its light receiving part is exposed through the opening 9 of the calculation unit 3. There is. L.S.
An arithmetic circuit constructed using I and the like is mounted on a printed circuit board 13 housed inside the arithmetic unit 3. The output signal line of the keyboard 2, the power output line of the solar cell 5, the output signal line for the display 7, etc. are connected to predetermined locations on the printed circuit board 13.

Next, the internal structure of the display unit 6 is similarly shown in FIG. 3. In the state shown in FIG. 1, the display unit 6 is housed in the four parts 3e on the upper surface of the arithmetic unit 3 by a folding structure which will be described later. The display 7 consisting of an LCD unit is fixed to the rear side of the display unit 6 at 56d by a positioning member such as a damper (not shown), and its display surface is fitted with a protective glass or the like on the old surface of the display unit 6. The exterior is visible from the opening 11.

The display unit 6 is configured to have dimensions that allow it to be stored in the four parts 3e on the top surface of the calculation unit 3, and in order to prevent it from jumping out from the calculation unit 3 in the storage position, the display unit 6 is constructed so that it can be stored in the front part of the display unit 6 as shown in FIG. Attach two claws 6b to the edge of the
Also, correspondence 1. of the front wall part of the fourth part 3e. A notch 3b is formed at the position shown in FIG. Therefore, the display unit 6
When the display unit 6 is stored in the recess 3e, the display unit 6 can be locked in the storage position by fitting the claw 6b and the notch 3b.

In addition, in order to open the arithmetic unit 3 locked in the recess 3e as shown in I:, a notch 6a is provided on the edge of the display unit 6 so that a fingernail or the like can be hung thereon.
Furthermore, a notch 3a is provided in the side wall within the corresponding recess 3e.

The keyboard unit 1, arithmetic unit 3, and display unit 6 having the above-described structures are coupled as follows. As shown in FIGS. 1 and 2, the keyboard unit 1, the arithmetic unit 31, and the display unit 6 each have a hinge part 1 which is alternately assembled at the joint end.
a, 3C1 and 6C. A spring pin 8 is fitted through an opening I7 in the center of these hinge parts.

The spring pin 8 is made of a metal rod or the like having a predetermined elasticity, and has a slightly bent shape. Therefore, when the spring pin 8 is fitted into the linear opening of each hinge part la, 3c, 6c, the spring pin 8 comes into pressure contact with the inner surface of the opening of the hinge part, and the keyboard unit 1, the arithmetic unit 3, and the display unit 6 It works to hold the person at that position.

Moreover, by rotating each part against the force of the spring pin 8, the keyboard unit 1, the arithmetic unit 3, and the display unit 6 can each be swung to a desired angle.

First, store the display unit 6 in the recess 3e of the arithmetic unit 3, open the arithmetic unit 3 in the direction A in FIG. By releasing , the arithmetic unit 3 including the display unit 6 can be fixed at a desired angle by the action of the spring pin 8 . Figure 1 shows a state where the opening angle of the calculation unit 3 in the A direction is 180°, but the fourth
As shown in the figure, the position of the arithmetic unit 3 can be fixed by the spring pin 8 even at an angle within this range. Such usage is similar to a conventional folding calculator.

Also, from the state shown in FIG. 1, the notch 3a of the calculation unit 3
Insert the nail of finger F into the inside, hang it on the notch 6a of the display unit 6, and pull it in the direction B as shown in Fig. 5 to remove the nail 6b.
By releasing the notch 3b, only the display unit 6 can be opened. In this case as well, the opening angle of the display unit 6 relative to the arithmetic unit 3 in the direction B can be arbitrarily determined, and can be fixed at a desired angle by the action of the spring pin 8.

That is, considering the keyboard unit 1 as a reference, the aperture angle of the arithmetic unit 3 is arbitrary in the A direction, and the aperture angle of the 1 display unit 6 is arbitrary in the B direction with respect to the arithmetic unit 3, so in the end, the keyboard unit 1, the arithmetic unit 3, and the display unit 6 can be opened to any desired swing angle and fixed at that position.

Therefore, the opening angle of the arithmetic unit 3 is determined to be convenient for the power generation of the solar cell 5, and the opening angle of the display unit 6 is determined so as to set an appropriate viewing angle according to the operator's posture. It is possible to fully operate the device after satisfying all the operating conditions of the device or the operating conditions of the operator, which are determined according to the operating item boundaries, and the operability at that time can be greatly improved.

Further, according to the above configuration, the keyboard unit 1. The center of rotation when swinging the arithmetic unit 3 and the display unit 6 is approximately the straight line 0 at the center of the spring bin 8, as shown in FIGS. 1 and 2. That is, the keyboard unit 1, the calculation unit 3, and the display unit 6
Since the centers of rotation when swinging are all the same,
Since the common rotation mechanism of one spring pin 8 can rotate as shown in E, the structure of the device can be simpler and cheaper than when each rotation mechanism is provided independently.

The above configuration can be widely applied to electronic devices other than the calculator shown in Section F. In addition, if the device is composed of a larger number of rotatable parts than the embodiment described in E, and a plurality of rotation mechanisms are provided, the rotation center of any one of the rotation mechanisms can be used. All you need to do is connect the display units.
In addition, the display is not limited to an LCD unit, and even if it is of another type, the angle that is easy to see according to the operator's posture is 1! ;The effect of being beaten remains the same.

[Effects] As is clear from the following explanation, the present invention is effective for electric appliances in which the device is composed of a plurality of parts connected via a rotation mechanism so that the device can be folded. , the display unit for displaying the calculation results and operating status is connected in a foldable manner via at least the rotation mechanism whose rotation center is aligned with the rotation mechanism, so that it is easy to adapt to the operating environment. To provide an excellent electronic device that can completely operate a device on a hill that satisfies all the operating conditions of the device or the operating conditions of the operator determined according to the conditions, and can greatly improve the operability at that time. can.
