Abstract

PURPOSE:To attain the adjustment of the scroll speed or the like and to improve the operability by providing a transducer detecting the depression quantity of a key switch and outputting an electric signal corresponding to the depression quantity. CONSTITUTION:Operation key switches 2-7 for scrolling or the like are provided to, e.g., right size of a keyboard main body 1 and the key switches 2-7 have a key top 8, a plunger 9 and a spring 10 energizing the key top 8 upward. A transducer 11 is provided to the lower end of the plunger 9 and the depression quantity is detected in response to a pressure exerting the transducer 11 via the plunger 9 and an electric signal corresponding to the depressing quantity is outputted. Then, the outputted electric signal is inputted to a CPU and the speed control for the scroll of the display device or the like is applied. Thus, the speed for scrolling or the like is varied in response to the key switch depressing quantity so as to improve the operability.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a keyboard used as input/output for workstations, measuring instruments, etc., and particularly to a keyboard with highly functional key switches for screen operation.

[Conventional technology]

On keyboards used as input means on workstations, etc., screen scrolling and cursor movement (
It is well known that a key switch for scrolling (hereinafter referred to as scrolling, etc.) is provided.

In conventional keyboards, such key switches have a binary detection function of on and off like other key switches. For example, scrolling or the like is performed when the key switch is in the on state when the key switch is pressed down, and scrolling or the like is performed when the key switch is in the off state when the key switch is raised when the key switch is released.

[Problem to be solved by the invention]

In the conventional keyboard mentioned above, the key switch state can be set to 2.
Since it is expressed as a value, the speed of scrolling, etc. is constant, and the operator cannot freely control this speed. As a result, if the amount of scrolling, etc. is small, care must be taken to stop at the target position, and if the amount of scrolling, etc. is large, the waiting time will be long.

The present invention has been made in view of the above circumstances, and aims to provide a keyboard that can change the speed of scrolling, etc. depending on the amount of depression of a key switch, and can improve operability.

[Means to solve the problem]

The keyboard according to the present invention is characterized in that it is equipped with a transducer that detects the amount of depression of a key switch and outputs an electrical signal corresponding to the amount of depression. This allows adjustment and thereby achieves the above objective.

〔Example〕

Hereinafter, one embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a plan view of the entire keyboard, FIG. 2 is an enlarged side view of the key switch section, and FIG. 3 is a characteristic diagram.

As shown in FIG. 1, the keyboard of this embodiment is provided with key switches 2 to 7 for scrolling and other operations, for example, on the right side of the keyboard body 1. As shown in FIG. To illustrate the functions of these key switches, key switch 2 is rROL.
L UPJ, key switch 3 is "ROLL DoWN"
”, key switch 4 is “↑”, key switch 5 is “-”
, the key switch 6 represents "↓", and the key switch 7 represents "→".

As shown in FIG. 2, these key switches 2 to 7 include a key top 8 and a plunger 9 that supports this key top 8.
and a spring 10 provided around the plunger 9 and urging the key top 8 upward. A transducer 11 is provided on the lower end side of the plunger 9, and the depression pot is detected according to the pressure acting on the transducer 11 via the plunger 9, and an electric signal corresponding to the amount of depression is output. The output electric signal is then manually inputted to a CPU (not shown), and speed control such as scrolling of the display is performed based on the CPU.

Pressing force on key top 8 and transducer 11
The relationship between the amount of electricity generated and the amount of electricity generated is such that it increases proportionally within a predetermined pressing force range, as shown by curve a in FIG. 3, for example.

According to the configuration of this embodiment, when the operator presses down the key top 8 by a large amount, scrolling, etc. is performed at high speed, and when the operator presses down the key top 8 by a small amount, scrolling, etc. is performed at low speed. Therefore, for example, the speed can be adjusted to low speed when the amount of scrolling is small, and high speed when there is a large amount of scrolling, etc., eliminating the need for extra attention and waiting time, and increasing the speed of key operation. It will be possible to make it more functional.

〔Effect of the invention〕

As described above, according to the keyboard according to the present invention, the speed of scrolling etc. can be changed according to the key switch depression 1, and the excellent effect of improving the operability is achieved.
