Abstract

PURPOSE:To offer an electronic equipment of simple, inexpensive structure which has good operativity and reduces fatigue even in long-time use by providing a palm rest means which is turnable and can be put in the equipment housing at the front side end part of a keyboard to the equipment housing. CONSTITUTION:The palm rest 8 is turned around bosses 8a as shown by an arrow P and stored as shown by a two alternate long and short dashes line when the equipment is not used. At this time, lock means such as claws are provided between side plates 8h nearby the bosses 8a and flanks of the equipment housing 5 so that the palm rest 8 does not move at a store position shown in a figure. While the palm rest 8 is open, the flat part 8b of the palm rest 8 forms a slanting surface connecting with a keyboard part and an operator can rest his or her hands on the part during operation and place his or her wrist parts on the palm rest 8 at any time, so the fatigue is small and the operation efficiency does not decreases even when the equipment is used for a long time.

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.

In addition, due to miniaturization and design constraints, it is becoming difficult to maintain a large gap 1 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-mentioned problems.
The purpose of the present invention is to provide an electronic device that has an inexpensive structure, has good operability, and causes less fatigue 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 having a keyboard. A configuration with a retractable palm rest has been adopted.

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

2 and 3 are side and perspective views showing the structure of an embodiment of an electronic typewriter according to the present invention. In FIG. A keyboard 1 is provided on the top surface of the computer 5, and although not shown here, it is assumed that the keyboard has functional sections similar to those shown in FIG. 1 in front of or inside the keyboard. In this embodiment, a palm rest 8 is provided at the front end of the device housing 5 .

That is, as shown in FIGS. 2 and 3, the palm rest 8 has a flat portion 8b that has almost the same inclination angle as the keyboard surface of the device housing 5 when opened, and a flat portion 8b.
It consists of side plates 8h, 8h integrally formed in an elliptical shape to ensure the above-mentioned angle of the flat part on the left and right sides. Inside the side plate 8h of the palm rest 8, there are four parts 8g each on the left and right sides.
These four parts 8g are fitted with bosses 8a provided on the front side of the side surface of the device housing 5, so that the device housing 5 and the palm rest 8 are swingably coupled.

In such a configuration, when the device is not in use, the palm rest 8 is rotated about the post 8a in the direction of arrow P in FIG. 3, and is stored in the position shown by the two-dot chain line in FIG.

At this time, it is preferable to provide a locking means (not shown) such as a claw between the side plate 8h near the post 8a and the side surface of the device housing 5 so that the palm rest 8 does not move at the illustrated storage position.

As shown in FIG. 3, when the palm rest 8 is open, the flat part 8b of the palm rest 8 becomes a slope that is continuous with the keyboard part, and the operator can rest his hands on this part during operation. Since the wrist part can be placed on the palm rest 8 at all times, there is little fatigue even when using the device for a long time, and work efficiency is not reduced.

As shown by reference numerals 8c and 8d in FIG. 3, the cross section of the palm rest 8 is thin at the flat portion 8b, and thickened by rounding the front side thereof. Therefore, the second
As shown in the figure, the groove 8 for storing the meat pressure part on the front side
If the palm rest 8 is provided on the bottom surface of the device casing 5, the palm rest 8 can be sufficiently stored within the height of the bottom of the device casing 5, which is provided by the rubber feet 81 and the like. Furthermore, a rectangular opening 8e is provided at the front center of the palm rest 8, and the device housing 5 can be carried using this opening 8e as a handle.

As described above, according to this embodiment, the structure includes a foldable palm rest, which makes the keyboard extremely easy to operate, and also allows the palm rest to be stored when not in use, so it can be placed on the desk. It is possible to provide an electronic device that requires less space and has an excellent design. Further, by providing the palm rest with a portion that functions as an integral handle, it also has the effect of facilitating the transportation of the device.

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 casing having a keyboard, the device casing at the near end of the keyboard can be rotatably attached to the device casing. It has a structure with a palm rest that can be stored in the machine, making it easy to operate, allowing for efficient work with less fatigue even when used for long periods of time, and having an excellent design that does not require a large work space. and can provide excellent electronic equipment.
