Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an electronic device, and particularly to an electronic device having an operating section on the top surface of the device body.

[Prior Art] Keyboard devices such as electronic desktop calculators and computer devices are known as electronic devices that operate the device through operating means such as a keyboard on the top surface of the device. Various improvements have been made to this type of device to prevent fatigue from accumulating in the operator's arms and fingers even when used for long periods of time.

FIG. 3 shows an example of the conventional structure of the keyboard section of an electronic device. A keyboard 3 having a predetermined number of key tops 31 arranged therein is provided. Rubber feet 5 for installing the device are provided on the lower surface of the lower case 11. A palm rest 13 that is raised higher than the keyboard 3 is provided between the end of the keyboard 3 on the operator side and the end of the device. By placing the base portion 61 of the palm of the operator's palm on this palm rest 13, the bottle maker can continue the operation easily without applying extra force to the wrist.

[Problems to be Solved by the Invention] However, in the conventional structure shown in FIG. There was a problem that it did not fit well with the hands of other people. Also,
There is a known technique for improving the stability of the wrist by providing a recess in the upper surface of the palm rest 13 in advance in a shape that roughly corresponds to the base of the palm, but such a structure is fixedly provided. Due to individual differences, there were cases where the hands did not fit on the palm rest, making it impossible to perform operations simply by moving the fingers.

Furthermore, in the conventional structure, as shown in Fig. 3, the rubber feet on the front side of the device are located closer to the center of the device than the end on the front side of the device. There is a problem in that when a force is applied to the device, the rear part of the device lifts up in the Q direction using the rubber feet 5 on the front side as a fulcrum.

[Means for Solving the Problems] In order to solve the above problems, in the present invention, in an electronic device having an operation section on the upper surface of the device main body, the operator side end of the operation section and the main body of the device are connected. The structure was adopted.

[Function] According to the above configuration, the highly viscous fluid that makes up the palm rest deforms to fit the operator's hand according to the shape of the operator's hand. There is no problem getting worse.

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

1 and 2 are a perspective view and a side view showing the configuration of an electronic device employing the present invention. FIG. 2 shows the structure of the device from the same direction as the conventional example shown in FIG.

The illustrated electronic device l is an electronic desktop calculator, and like the conventional device, its case is composed of an upper case 12 and a lower case 11, and a keyboard 3 with key tops 31 arranged on the upper surface of the upper case. It is configured. On the other side of the keyboard 3, a display section 24 is provided that protrudes from the top surface of the upper case, and this section includes the device keyboard 3, which includes the liquid crystal display 1, etc., and the front end of the device that corresponds to the operator side. The upper case l2 between the two is cut out, and a palm rest l3 is provided in this part. As shown in FIG.
It is wrapped in 4. The flexible sheet material 14 is made of a flexible sheet such as a soft vinyl chloride sheet, polyester sheet, polyurethane sheet, polypropylene sheet, polyethylene sheet, etc., and the highly viscous fluid 4 is made of gelatin, clay, starch paste, etc.

Further, in this embodiment, the rubber feet 5 for installing the device are placed tightly against the end of the installation surface on the bottom surface of the lower case, as shown in FIG.

According to the above configuration, when the operator places the wrist or the base of the palm of the hand 6 on the palm rest 13, the highly viscous fluid 4 wrapped in the flexible sheet material 14 is placed on the hand 6.
It deforms and fits depending on the shape or how it is disciplined. Therefore, the operator's wrist is stabilized and the device can be operated with ease. The pressing force of the hand placed on the palm rest is not applied to a single point of the hand, reducing operator fatigue and greatly improving the feeling of operating the device.

In addition, in the above configuration, the rubber feet are provided at the bottom edge of the device below the palm rest, so even if force is applied from above via the palm rest by the operator's wrist, the device will not be installed as shown in Figure 3. Does not rise from the surface,
A stable installation condition can be maintained.

Although an electronic desktop calculator has been exemplified as an electronic device above, the above technology can also be applied to other devices, such as the structure of a computer keyboard itself. Although rubber feet are shown above as the installation member for the device, other types of installation members may be used. Moreover, the material of the palm rest is not limited to the above, and various materials can be used.

[Effects of the Invention] As is clear from the above, according to the present invention, in an electronic device having an operating section on the upper surface of the device main body, the operator side end of the operating section and the operator side end of the device main body are Since the palm rest is made of a flexible sheet material wrapped in a highly viscous fluid on the top surface of the device, the highly viscous fluid that makes up the palm rest deforms depending on the shape of the operator's hand. Since the electronic device fits in the operator's hand, it is possible to provide a durable electronic device that can reduce the fatigue level of the operator and improve the operational feeling without the problem of deterioration in operability due to individual differences among operators.
