Abstract

PURPOSE:To offer an electronic equipment of simple, inexpensive structure which is excellent in operativity and reduces fatigue even when the equipment is used for a long time by providing a member which shields a keyboard and using this keyboard shield member as a palm rest during equipment operation. CONSTITUTION:The keyboard cover 8 has side places 8h and is provided with lock means 8a' composed of recessed or projection parts inside of the forward prolongation parts of the side plates, and lock means 8a composed of projection or recessed parts are provided to an equipment housing 5 at corresponding positions. Therefore, the keyboard cover 8 is fixed to the equipment housing 5 firmly by those lock means when mounted and also detached by spreading the prolongation parts of the side plates of the keyboard cover 8. Consequently, the keyboard cover 8 forms a slanting surface connecting with a keyboard part and an operator can rest his or her hands on this part during operation.

Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to electronic equipment, and more particularly to electronic equipment having a keyboard, such as a typewriter or word processor.

[Prior Art] In recent years, devices with keyboards such as electronic typewriters, word processors, and personal computers have become smaller and more portable devices are being produced.

FIG. 1 shows the general structure of a device of this type.

The device shown in FIG. 1 has a keyboard 1 and a display section 2 arranged on the top surface of a device housing 5, and a printer 3 and a power supply section 4 inside.
, and a board 6.7 on which a power supply circuit, a drive circuit, a control circuit, etc. are mounted. In order to house various functional parts as described above, the equipment housing 5 includes boards 6 and 7.
In many cases, keyboards have a plurality of keyboards, and therefore there is a limit to how thin the entire device can be made to be, and it is becoming difficult to reduce the height h of the operating surface of the keyboard l.

Furthermore, due to miniaturization and design constraints, it is becoming difficult to maintain a large gap between the front end of the keyboard l and the front end of the device housing 5, and as a result, the operator has no member to rest his hands during operation. However, when operating the keyboard, the user is forced to hold his or her hands in the air, which causes fatigue and reduces efficiency when used continuously for a long period of time.

[Purpose] The present invention has been made in view of the above problems, and it is an object of the present invention to provide an electronic device that has a simple and inexpensive structure, has good operability, and is less tiring even when used for a long time. .

[Structure of the Invention] In order to achieve the above object, the present invention provides an electronic device having a device casing with a keyboard, and provides a member for concealing the keyboard, and the keyboard concealing member is used as a palm rest when operating the device. A configuration was adopted.

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

[First Embodiment] FIGS. 2 to 4 are side and perspective views showing the structure of an embodiment of an electronic typewriter according to the present invention. In FIG. A keyboard l is provided on the top surface of this device housing 5, and
Although not shown here, it is assumed that the keyboard has a functional section similar to that shown in FIG. 1 in front of or inside the keyboard. A keyboard cover 8 made of plastic or the like is provided to hide the keyboard.

The keyboard cover 8 is formed into a substantially trapezoidal box shape as shown by broken lines in FIGS. 2 and 3, and is configured to cover the keyboard 1, so that dust, dirt, etc. can be removed from the gaps between the keys of the keyboard when the device is not in use. It is designed to prevent intrusion.

As seen in the perspective view of FIG. 4, the keyboard cover 8 has a side plate 8h, and a locking means 8a' consisting of a recess or a protrusion is provided on the inside of this forward extending portion. As shown in FIG. 3, a locking means 8a consisting of a corresponding convex portion or concave portion is provided at a corresponding position. Therefore, when the keyboard cover 8 is attached, the locking means securely fixes the keyboard cover 8 to the device housing 5, and the keyboard cover 8 can be removed by, for example, expanding the extended portion of the side plate of the keyboard cover 8.

When using the device, as shown in FIG. 3, the keyboard cover 8 is removed as described above, and the side plate 8 is
A locking means 8 in which a locking means 8a' of h is provided at the front of the equipment casing.
a” (see Figure 2) to secure it.

As a result, as shown in FIG. 4, the keyboard cover 8 becomes a slope that is continuous with the keyboard section, and the operator can rest his hands on this part during operation.
Furthermore, since the wrist part can be placed on the keyboard cover 8 at all times, there is little fatigue even when using the device for a long time, and work efficiency is not reduced.

As described above, this embodiment has a structure in which a removable keypad cover is provided, which improves the operability of the keyboard, and also allows the keyboard cover to be used as a keyboard cover when not in use. It is possible to provide an electronic device that requires less desk space and has an excellent design.

[Second Embodiment] FIGS. 5 to 8 show a second embodiment of the present invention. In this embodiment, a part of the keyboard cover is constructed as a rotatable foldable member. There is.

That is, a part of the keyboard cover consists of a box-shaped keyboard cover 9 similar to that of the previous embodiment, and a flat printer cover 10 rotatably connected to the box-shaped keyboard cover 9 via a hinge portion 9b. As shown in FIG. 5, the keyboard cover 9 is rotatably coupled to the device housing 5 by a locking portion 9a. The locking portion 9a has a shaft inside thereof, and this shaft engages with the bearing portion 5a shown in FIG.

In the above configuration, when the device is not in use, the keyboard cover 9 and printer cover 10, which have approximately the same width W as the device casing 5, are spread over the top surface of the device casing 5, as shown in FIGS. 5 and 6. Furthermore, the keyboard cover 9 covers the keyboard l, and the printer cover 10 covers the mechanical part 5b of the printer (see FIG. 8).

Therefore, when the apparatus is not in use, the keyboard cover 9 and the printer cover 10 completely prevent dirt and dust from entering the apparatus.

On the other hand, when using the device, the keyboard cover 9 is rotated around the bearing portion 5a as shown by arrow A in FIG.
Further, the printer cover 10 is rotated inward via the hinge portion 9b so as to be folded up. This results in
As shown in FIGS. 7 and 8, the printer cover 10 is folded over the keyboard cover 9, so that the upper surface of the printer cover 10 has approximately the same angle of inclination as the keyboard l. As a result, the keyboard cover 9 and printer cover 10 function together as a palm rest.
Operability can be improved in the same way as in the previous embodiment.

As described above, this embodiment has a structure with a foldable keyboard cover, which not only makes the keyboard extremely easy to operate, but also protects the keyboard and printer mechanism when not in use. It is possible to provide an electronic device that requires less desk space and has an excellent design.

Although the embodiments related to typewriters, word processors, etc. have been described above, the present invention is not limited thereto, and can be applied to various devices as long as they have a keyboard.

[Effects] As is clear from the above description, according to the present invention, in an electronic device having a device case having a keyboard, a member for concealing the keyboard is provided, and this keyboard concealing member is used as a palm rest when operating the device. The structure is easy to operate, allows for efficient work with less fatigue even when used for long periods of time, has an excellent design, does not require a large work space, and eliminates dust and dirt. It is possible to provide an excellent electronic device that is less likely to malfunction due to intrusion of dust or the like.
