Abstract
A computer keyboard capable of displaying contact key position consists of a computer keyboard used commonly, a contact-sensitive switch arranged on the key-presses of the keyboard, a contact key position displaying controller and a contact key position display provided with light displaying blocks which are corresponding to the key-presses of the keyboard. The contact key-presses of the keyboard are pressed and the contact key position displaying controller is touched, which light sources corresponding to the light displaying blocks on the contact key position display to display the contacted key-presses. When the keyboard is used to input data or information to the computer, the input operation can be completed rapidly and accurately just through watching the contact key position display.
Description
The utility model relates to a kind of computer keyboard.
The existing actual equal no touch key of the computer keyboard level display apparatus that uses, utilize the keyboard will be when computing machine input data or information while seeing that keyboard seeing that the display fluorescent screen keys in operation, energy disperses, influence typing speed, loading error takes place simultaneously easily, and this point is more obvious for computing machine beginner performance especially.
The purpose of this utility model provides a kind of computer keyboard that utilizes keyboard can show the membrane keyboard position when computing machine input data or information.
The computer keyboard that can show the membrane keyboard position by normally used computer keyboard, be loaded on touch sensible switch, the membrane keyboard position display controller on the keyboard and have the membrane keyboard position display of corresponding light displaying block to constitute with keyboard, touch sensible switch, light displaying block light source connect with membrane keyboard position display controller by shielded conductor.Press keyboard, membrane keyboard position display controller is lighted the keyboard that demonstrates touch with the corresponding displaying block light source with button on the display of membrane keyboard position.
A kind of comparatively desirable structural shape that can show the computer keyboard of membrane keyboard position is, by normally used computer keyboard, to be loaded on touch sensible switch that keyboard connects the computer keyboard of the shown membrane keyboard position that touch sensible switch, membrane keyboard position display controller and membrane keyboard position display on the key constitute be that diaphragm type touch sensible switch, the diaphragm type character shape touch sensible switch of respective keys markup character shape is installed on the button.Any one constitutes as element circuit the control circuit of membrane keyboard position display controller by the complementary amplification switch circuit of existing time-base integrated circuit, triode.Membrane keyboard position display is made of plate-like box body, the powerful light emitting diode of display panel, plate-like box body box chamber is divided into and keyboard shape, corresponding lattice chamber, key position by dividing plate, be shaped on the figure of corresponding key shape, markup character on the corresponding plate face in display panel dative chamber, LED source is fixed in each lattice chamber.The computer keyboard that utilization can show the membrane keyboard position only need see that when computing machine input data or information membrane keyboard position display can key in operation, energy concentrates, keys in rapidly, accurately, key in the energy that operation can keep the long period and concentrate, the computing machine beginner use can very fast skilled keyboard the key entry operation.
Accompanying drawing is an embodiment of the present utility model, further specifies the utility model below in conjunction with embodiment.
Fig. 1 is the appearance assumption diagram that can show the computer keyboard of membrane keyboard position.
Fig. 2 is the A portion partial enlarged drawing (part is removed display panel) of Fig. 1.
Fig. 3 is the B portion partial enlarged drawing (sectional structure) of Fig. 1.
As shown in the figure, the computer keyboard that can show the membrane keyboard position is by normally used computer keyboard (3), be installed in the diaphragm type touch sensible switch (17) of making respective keys markup character shape on the keyboard (18), the power switch (7) that has power light, input, output wiring terminal (5), (9) and the membrane keyboard position display controller (8) of attaching plug (6) and the film key position display (1) that touches that is fixed on the graphoscope (2) when using constitute, diaphragm type touch sensible switch connects with membrane keyboard position display controller input terminal by shielded conductor (4).The display control circuit of membrane keyboard position display controller is by any one constitutes as element circuit in existing time-base integrated circuit, the complementary amplification switch circuit of triode.Membrane keyboard position display is made of plate-like box body (15), display panel (12), powerful light emitting diode (16), plate-like box body box chamber is divided into and keyboard shape, corresponding lattice chamber, key position (14) by dividing plate (13), is shaped on the figure (11) of corresponding key shape, markup character on the corresponding panel in display panel dative chamber.Powerful light emitting diode is fixed in each lattice chamber, by shielded conductor (10) with touch film key position display controller output wiring terminal and connect.Membrane keyboard position display controller connects rear indicator light by plug with supply line to be lighted, and can key in operation behind the power-on switch.Membrane keyboard position display controller is lighted the button that demonstration presses with the powerful light emitting diode of displaying block corresponding with button on the display of membrane keyboard position during button on pressing keyboard, thereby only need see in data or the information process membrane keyboard position display can rapidly, accurately be finished and keying in operation that the displaying block diode promptly extinguishes immediately after finger leaves keyboard keying in to computing machine.
Claims (2)
1, a kind of computer keyboard that shows the membrane keyboard position, it is characterized in that by normally used computer keyboard, be loaded on touch sensible switch, the membrane keyboard position display controller on the keyboard and have the membrane keyboard position display of corresponding light displaying block to constitute that touch sensible switch, light displaying block light source connect with membrane keyboard position display controller by shielded conductor with keyboard.
2, by the described computer keyboard that shows the membrane keyboard position of claim 1, it is characterized in that the said diaphragm type touch sensible switch that the film inductive switch is a respective keys markup character shape that touches, film electricity formula touch sensible switch is installed on the button, the control circuit of membrane keyboard position display controller is by existing time-base integrated circuit, any one constitutes as element circuit in the complementary amplification switch circuit of triode, membrane keyboard position display is by the plate-like box body, display panel and powerful light emitting diode constitute, plate-like box body dish chamber is divided into and the keyboard shape by dividing plate, corresponding lattice chamber, key position, be shaped on and corresponding key shape on the corresponding plate face in display panel dative chamber, the figure of markup character, light emitting diode are fixed in each lattice chamber.
