Problems solved by technology

Since the jog shuttle knob 1 in the prior art needs to be equipped with five-press switches 16a-16e to perform the five-way key function, for the jog-shuttle knob 1, adding five-press switches 16a-16e will increase the manufacturing cost and the complexity of circuit wiring

Embodiment Construction

[0049] In order to have a further understanding of the purpose, structure, features, and functions of the present invention, the following detailed descriptions are provided in conjunction with the embodiments.

[0050] Certain terms are used in the description and claims to refer to particular elements. Those of ordinary skill in the art will appreciate that manufacturers may refer to the same element by different terms. The specification and claims do not use the difference in name as a way to distinguish components, but use the difference in function of components as a criterion for distinguishing. "Include" mentioned throughout the specification and claims is an open term, so it should be interpreted as "including but not limited to".

[0051] see Figure 2 to Figure 5 , figure 2 It is a schematic top view of the multi-directional key structure 3 according to an embodiment of the present invention, image 3 for figure 2 The cross-sectional schematic diagram of the m...

Abstract

The invention discloses a multi-direction key structure and an execution method of direction keys thereof. The multi-direction key structure comprises a base, a cover, a first optical coupler, a second optical coupler and a processor. The cover is movably disposed on the base and comprises two sidewalls facing the base; the first optical coupler is disposed on the base between the base and the cover; the second optical coupler is disposed on the base between the base and the cover; the processor is electrically connected to the first optical coupler and the second optical coupler. When the cover is under pressing, the two sidewalls cover at least one of the first optical coupler and the second optical coupler, so that the processor executes functions of the corresponding direction keys according to covering signals generated by the first and second optical couplers.

Description

technical field [0001] The present invention relates to a multi-directional key structure and a method for executing the function of the direction key, in particular to a multi-directional key structure and a method for executing the function of the direction key by using two optical couplers to perform the function of the direction key without pressing a switch. Background technique [0002] see figure 1 , figure 1 It is a schematic top view of a jog shuttle knob 1 with a five-way key function in the prior art. Such as figure 1 As shown, the jog shuttle knob 1 includes a base 10, a cover 12, two optical couplers 14a, 14b, and five push switches 16a-16e. The two optical couplers 14 a, 14 b and the five push switches 16 a - 16 e are all disposed on the base 10 and between the base 10 and the cover 12 . When the user operates the cover 12 to rotate clockwise or counterclockwise relative to the base 10, the two optical couplers 14a, 14b can be shielded successively through ...
