Abstract

The utility model relates to an optical mouse, comprising a base seat. The base seat is provided with a transmitter and a receiver to get the position coordinate. A transparent or half transparent inducting board is arranged above the transmitter and the receiver. A containing room is provided to contain the inducting board, and the inducting board can move forward and backward, leftward and rightward inside the containing room. The inducting board reflects the signal transmitted by the transmitter to the receiver so as to detect the position coordinates. Thereby, when the inducting board has certain displacement, the position change of the cursor can be marked by calculating the change of the displacement so as to achieve the proposal of moving the cursor.

Description

Optical mouse

Technical field

The utility model relates to a kind of optical mouse, relates in particular to a kind ofly with the moving of tablet, and via the change that optics records displacement, comes the optical mouse of moving cursor position.

Background technology

General modal is to operate with mouse, easily says it in order to control the position of onscreen cursor, and the bottom of mouse is provided with a roller, and when mouse moved, roller can rotate and the inductor of touch mouse inside, drove cursor and moved its position.Another kind of steer mode is to accept the user with Trackpad to move on Trackpad, and utilizes the principle of electro-induction, detects amount of movement, changes the position to drive cursor.

The problem of the precision of Trackpad own and the problem of permanance are always perplexed by the user, moreover the cost of Trackpad is than higher, are subject to the external careless application of force and factor such as destroy and also make Trackpad can't really bring into play practical effect.As for mouse is one to add object, and it is unavoidable extremely to make the facts such as assembling, and especially traditional wire mouse more has the trouble of wiring, has the existence of roller pollution problems even wireless mouse still has as wire mouse.

Basically, the utilization of mouse mainly is to move essential instrument at cursor in the computer screen, but in the use of computing machine, necessarily have the existence of keyboard, mouse is if stand-alone assembly, its congenital problem is necessarily unavoidable, if mouse function can be arranged on the keyboard, greatest practicality will be arranged.

Summary of the invention

Therefore, the utility model people at first is arranged on the keyboard as basic design direction at mouse function, moreover, break away from the electro-induction use-pattern of Trackpad and the pattern that is provided with of roller, be to devote considerable time and spirit, concentrated research, study through repeatedly testing, also experience the repeatedly experience of failure, develop a kind of optical mouse now eventually, really overcome the shortcoming in the conventional mouse design, and put forward the practicality of mouse widely.

Therefore, fundamental purpose of the present utility model is providing a kind of optical mouse, comprise a pedestal, installing one transmitter and a receiver in the pedestal, with the acquisition position coordinates, one tablet is installed in the top of transmitter and receiver, and one accommodation chamber put to hold for tablet, and tablet can be done moving all around in accommodation chamber, therefore the signal that the mat transmitter is launched records position coordinates through tablet reflected back receiver, when tablet to some extent during displacement, the change of displacement calculating amount is in order to change the position of cursor.

Optical mouse of the present utility model can be arranged on the keyboard of general computing machine, or on the keyboard of mobile computer, or other has in the suitable mechanism of the device that needs moving cursor, as long as the circuit mechanism that had both deposited via keyboard or other mechanism accepts the signal of optical mouse, and, all can use optical mouse of the present utility model in order to control cursor position and to change variables manner.

Description of drawings

For being described in more detail structure of the present utility model and technical connotation, below lift a preferred embodiment now, and conjunction with figs. is illustrated, and following cited embodiment is the usefulness for explanation the utility model, and unrestricted the utility model, such as the replacement of all equivalent elements or modification must be subordinate to category of the present utility model.

Fig. 1 is that the utility model optical mouse is assembled in the synoptic diagram on the keyboard.

Fig. 2 is a sectional view, shows the relevant position of transmitter, receiver and the tablet of optical mouse of the present utility model.

Fig. 3 is a stereographic map, shows that optical mouse of the present utility model is arranged on the keyboard of mobile computer.

Embodiment

See also Figure 1 and Figure 2, optical mouse 10 of the present utility model comprises a pedestal 20, installing one transmitter 30 and a receiver 40 in the pedestal 20, transmitter 30 in order to emission signal and receiver 40 in order to receive signal, one tablet 50 is installed in the top of transmitter 30 and receiver 40, tablet 50 can be transparent panel or translucent sheet, and a housing 60 is provided with an accommodation chamber 61 and inserts to hold for tablet 50, and tablet 50 can be done all around mobile in accommodation chamber 61.

The signal of launching when transmitter 30, get back to receiver 40 through tablet 50 reflection signals, and can record a position coordinates, when tablet 50 to some extent during displacement, transmitter 30 and receiver 40 record another coordinate position, the displacement that changes of coordinate position as calculated can be in order to driving the position change of cursor, is used for the purpose of moving cursor to reach optical mouse.

As shown in Figure 3, optical mouse of the present utility model also can be arranged on the keyboard of mobile computer, no matter be desktop PC or mobile computer, because both all have keyboard, and all be preset with relevant circuit design in the keyboard, data transmission that can optical mouse is measured reaches the purpose that the driving cursor moves to main frame.

In the same manner, except general personal computer, in other appliance and electronic such as industrial computer, personal digital aid (PDA) and electronic book device or the like, owing to all depend on cursor to come operation, therefore optical mouse of the present utility model also can be applicable on the suchlike product.

Obviously, optical mouse of the present utility model is utilized photoinduction to produce cursor and is driven, in use never have wearing and tearing or pollution problems, its serviceable life and permanance are significantly to promote, and the accuracy of optical sensor is that common mechanical structure institute can not reach, therefore the utility model optical mouse practicality that can reach is that traditional product can reach, obvious sufficient tool progressive and practicality.

In sum, optical mouse of the present utility model has been improved the shortcoming of traditional antenna pedestal really, and reaches its intended purposes and effect.

Claims

1, a kind of optical mouse comprises a pedestal, installing one transmitter and a receiver in the pedestal, one tablet is installed in the top of transmitter and receiver, and a housing, is provided with an accommodation chamber in the housing and inserts, and induction pole can be done all around mobile in accommodation chamber to hold for tablet:

The signal of launching when transmitter, get back to receiver through tablet reflection signal, and can record a position coordinates, when tablet to some extent during displacement, transmitter and receiver record another coordinate position, the displacement that changes of coordinate position as calculated can be in order to driving the position change of cursor, is used for the purpose of moving cursor to reach optical mouse.
