JPH1115586A - Ten-keyboard - Google Patents

Abstract

PROBLEM TO BE SOLVED: To eliminate the strain of a wrist and the upper parts of arms and to improve the efficiency of various input works by providing a hand rest part on the front end side of ten keyboard so that it can be freely attached/detached. SOLUTION: This ten-keyboard is composed of a ten-keyboard main body 1, various keys 2 for inputting numeric values and operation marks and the hand rest part 3 provided on the end part of the front end side of the ten- keyboard main body 1. The hard rest part 3 is freely attachably/detachable provided for the ten keyboard main body 1. Namely, an engaged projection bar is provided for a ten keyboard main body 1-side and an engaged groove is bar-provided in position corresponding to the bar on a band rest 3-side. They are mutually engaged, are slid and can freely be attached/detached. The band rest part 3 can be adjusted to band skin at the time of work by making at least a surface as a soft material by coating the surface of a base material with the soft material of rubber and soft resin or executing coating work on the surface, for example.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a separate numeric keyboard which is used by connecting to a portable personal computer such as a notebook personal computer. It is provided in.

[0002]

2. Description of the Related Art In recent years, among computers widely used in offices and homes, a so-called notebook personal computer does not employ a full keyboard such as a 106-type keyboard, and in most cases does not have a numeric keypad for inputting numerical values. . For this reason, in the case of inputting a large number of numerical values, such as a spreadsheet, it is often the case that a dedicated so-called numeric keyboard is separately connected.

[0003] This conventional numeric keyboard has a numerical value of 0 to 9 and plus,
Keys of operation symbols such as minus, enter (return) key, etc. are arranged at predetermined positions, and the key surface as a whole has a compact shape with the rear slightly higher.

[0004]

However, the above-mentioned numerical input and calculation work generally takes a long time in many cases.
However, since the conventional numeric keyboard has the above configuration,
It is difficult to hit the top key when working with the wrist on the desk surface during input work, and it is necessary to always lift the wrist to perform the work. For this reason, the wrist and the upper arm become tired, which hinders the input operation. In addition, since the numeric keypad is compact and lightweight, when a part of the hand touches the edge of the main body when the wrist is lifted, the numeric keypad is easily moved, which hinders the input operation.

[0005]

According to the present invention, in order to solve the above-mentioned problem of the conventional numeric keyboard, a means is provided in which a hand rest is detachably provided at the front end of the numeric keyboard. In addition, at least the surface of the hand rest portion is made of a soft material so that it fits into the hand skin.

Further, in such a numeric keyboard,
A means for providing a slip prevention portion on the back surface of the handrest portion is employed.

The present invention according to the present invention improves the work efficiency by carrying out a work by placing a wrist on a handrest portion whose surface is made of a soft material. Also, at this time, the rear surface shift prevention unit prevents the ten-key keyboard from inadvertently moving, thereby improving the efficiency of the input operation.

[0008]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A numeric keypad according to the present invention will be described below in further detail with reference to an embodiment shown in the drawings.
1 and 2, reference numeral 1 denotes a numeric keypad main body, reference numerals 2 and 2 denote various keys for inputting numerical values and operation symbols, and reference numeral 3 denotes a handrest provided at a front end of the numeric keypad main body. The handrest section 3 is detachably provided on the numeric keypad main body 1. That is, as shown in FIGS. 3 and 4, a fitting ridge 4 is provided on the numeric keypad main body 1 side, and a fitting groove 5 is provided at a position corresponding to that of the hand rest section 3 side so that they fit each other. In this case, it is slidable and detachable.

[0009] The handrest section 3 is, for example,
The surface of the substrate may be covered with a soft material such as rubber or soft resin, or the surface may be coated, for example, so that at least the surface is made of a soft material so that it fits into the skin during work.

Further, near the front end side of the back surface of the hand rest portion 3 and the back surface of the numeric keypad main body 1, there are provided slip prevention portions 6, 6 made of rubber feet or the like.

The method of attaching and detaching the hand rest 3 is not limited to the above embodiment. For example, the hand rest 3 and the tenon may be engaged with engaging claws at positions corresponding to each other on the numeric keyboard side. Conventionally well-known coupling methods, such as providing a blind hole and enabling detachable coupling, can be adopted.

[0012]

As described above, the ten-key keyboard according to the present invention has a hand rest portion detachably provided on the front end side thereof. It is possible to efficiently perform various input operations without tiredness and upper arms. In addition, since the surface of the handrest portion is made of a soft material, the handrest portion is adapted to the hand skin at the time of work, and work efficiency is improved. In addition, since the slip prevention part is provided on the back side of the hand rest part side, when putting the wrist on the work, the slip prevention part is pressed against the desk surface by the weight of the wrist, and the numeric keypad itself moves carelessly The input operation can be performed extremely smoothly without causing any displacement or displacement.

Furthermore, since the hand rest portion is detachable, the hand rest portion can be detached during carrying to reduce the bulk, and the material and the color of the portion can be changed to be replaced with those according to the user's preference. . Further, even when the part becomes dirty or damaged, it can be replaced at any time.
