Abstract

The utility model relates to an automatic focusing starting mechanism of digital camera. A photo sensor is combined in a back release. When a finger of the user is placed on the back release to shade the photo sensor, a microprocessor detects the signal of the shaded light of the photo sensor and then controls a focusing mechanism to automatically implement the focusing. The user utilizes the light penetration or shading of the photo sensor to control the camera whether to carry out the automatic focusing. Also other touching members are used for being combined with a touching-type switch to replace the photo sensor. When the finger of the user touches the touching member, the touching-type switch can be turned on so as to ensure that the camera carries out the action of automatic focusing. The camera of the utility model delivers more convenient operation and can be better for taking ideal images.

Description

The automatic focusing actuating mechanism of digital camera

Technical field

The utility model relates to digital camera, refers in particular to the automatic focusing actuating mechanism of digital camera.

Background technology

See also shown in Fig. 1 (a), Fig. 1 (b), Fig. 1 (c), the automatic focusing actuating mechanism 10 of known digital camera is to be installed between casing 20 and the substrate 30.Automatically focusing actuating mechanism 10 comprises that shutter release button 11, spring 12, two-part switch 13 form; These spring 12 tops place shutter release button 11 inboards, and its bottom is coated on two-part switch 13 peripheries; This two-part switch 13 is incorporated into substrate 30 tops, and the top of this shutter release button 11 is subjected to the elastic force of spring 12, stretches out perforate 21 outsides of casing 20; These shutter release button 11 bottoms outwards are bent with shelves ends portion 111 and is resisted against casing 20 belows, makes shutter release button 11 can not break away from perforate 21; These shutter release button 11 inboard central authorities are extended with a bar 112, and these bar 112 bottoms are contacted with the top of two-part switch 13.When not depressing two-part switch 13 (shown in Fig. 1 (b)), the state that first switch 131 shown in Fig. 1 (c), second switch 132 all are not conducting.

See also shown in Fig. 2 (a), Fig. 2 (b), Fig. 2 (c), when the employee with this shutter release button 11 of finger presses, when making bar 112 touch first section switch of two-part switches 13 (shown in Fig. 2 (b)), first switch 131 shown in Fig. 2 (c) is conducting state, and second switch 132 still is not conducting state.The interior microprocessor of camera this moment detects this signal, promptly starts autofocus mechanism and focuses automatically.

See also shown in Fig. 3 (a), Fig. 3 (b), Fig. 3 (c), when the user more firmly pushes shutter release button 11 again, when making bar 112 further touch second section switch (shown in Fig. 3 (b)), the second switch 132 shown in Fig. 3 (c) also is conducting state.This moment, microprocessor detected this signal, promptly controlled camera and took action.

Known digital camera, the user must touch the two-part switch to the continuous two-part application of force of shutter release button, the action that starts focusing and take.If the user is unfamiliar with the mode of operation of the two-part application of force, or during misoperation, be easy to can't photograph because of pressing shutter release button, takeing for camera has problem, or promptly takes action because of not finishing automatic focusing, and absorbs unsharp image.And the mode of operation of this kind two-part application of force also is inconvenient to control strength, and is very inconvenient in the use.

Start the unhandy disappearance of focusing automatically for improving known digital camera, and propose the utility model.

The utility model content

Fundamental purpose of the present utility model is providing a kind of automatic focusing actuating mechanism of digital camera, and the user only is seated in finger on the shutter release button, can start automatic focusing, makes the shooting action simpler, convenient, more can absorb image clearly.

For achieving the above object, the utility model provides a kind of automatic focusing actuating mechanism of digital camera, be in shutter release button in conjunction with an optical inductor, this optical inductor connects circuit structure on the substrate with lead.When user's finger is placed on when covering optical inductor on the shutter release button, microprocessor detect optical inductor by the signal of shading after, promptly control Focusing mechanism and focus automatically.

For achieving the above object, the utility model provides the automatic focusing actuating mechanism of another kind of digital camera, is to touch member at shutter release button in conjunction with one, and this touches member with the contact witch in the circuit structure on the lead connection substrate.When user's finger contacts on this touch member, can start this contact witch, microprocessor is promptly controlled Focusing mechanism and is focused automatically after detecting the signal that this contact witch is activated.

The automatic focusing actuating mechanism of above-mentioned digital camera, wherein this touch member is a conducting strip.

Via above-mentioned explanation, when user's finger is placed on shutter release button of the present utility model top, do not need to pressing down the action of to focus automatically; When depressing shutter release button, the action that can take.The utility model can be exempted the user when using known digital camera to take, and the mode of operation of necessary two-stage pressing shutter release button is so make the shooting action more simple, convenient; And can avoid the user to be unfamiliar with the two-period form mode of operation and cause puzzlement when taking, or imperfect tense depress shutter release button, and photograph unsharp image in focusing.
