Abstract

This invention relates to an anti-handshake button structure of an imaging device. It comprises of a cantilever and a switch component. The cantilever has two terminals and is elastic. One terminal is fixed so the cantilever can be attached and fixed at the shell of an electronic product. The other terminal of the cantilever is movable; furthermore, the aforementioned switch component is set up on the movable terminal of the cantilever. The switch component has a contact point which is activated and deactivated after be pressured. Since the switch component is mounted on the movable terminal of the cantilever and when the contact point on the switch component is pressured, the pressure resistance of the movable terminal of the cantilever is smaller than the conducting pressure resistance received at the contact point of the switch component. Therefore, even the movable terminal is displaced, the switch component remains stationary. Until the conducting pressure resistance at the contact point of the switch component is smaller than the pressure resistance of the movable terminal, the switch component is then being pressed and triggered an activation action. Utilizing the aforementioned cantilever type of design, the goal of anti-handshake is achieved with super low cost.

Description

Anti-shock button structure of camera

The invention relates to a button structure, in particular to an anti-shock button structure of a camera device, which is a cantilever design that generates a long touch stroke when the button is pressed, and absorbs the hand vibration during the stroke. The button design for the anti-shock.

Despite the rapid development of electronic technology, many devices have moved in the direction of automation control, but there are still many devices or devices that rely on manual operations, such as camera devices used in daily life, such as digital cameras, digital cameras (DV), and nets. When a still camera (camera) is used for capturing a still image (photographing), the camera must press the shutter by hand after confirming that the framing meets the requirements. Although it is a very simple button action, not everyone can cope with any situation at any time and place. One of the biggest problems when people take pictures is the hand shake problem, which is blurred by the hand vibration when the shutter is pressed. This condition is particularly prone to low light sources or under-lit operating environments.

In order to solve the aforementioned hand-shock problem, many digital cameras and digital cameras have built-in anti-shake (AS) functions. The technical principles of anti-shake can be divided into optical or digital (using software or The firmware is compensated). However, whether it is optical anti-shake or digital anti-shake, whether it is from a cost or technical point of view, there is a certain level of questioning, so it is easy for the average consumer to find digital cameras and digital cameras of a certain specification or more. Camera phones will be equipped with anti-shake function. As for lower-end digital cameras and digital cameras, almost no anti-shake function is available. Under the consideration of technical cost, the foregoing situation may be understandable, but it is not changed to the fact that even low-end products have strong demand for anti-shake function. Therefore, under the consideration of cost and technical considerations, the anti-shock function of low-end products is given, and even as an auxiliary design of high-order product vibration suppression system, it is necessary to actively seek feasible solutions.

Accordingly, it is a primary object of the present invention to provide an anti-shake button structure that employs a cantilever-to-button support to create a longer actuation stroke when the button is touched and absorbs hand vibration during the process to obtain an arm defense The effect of the hand shake.

The technical means for achieving the foregoing purpose is that the anti-shock button structure comprises: a cantilever having two ends and being elastic, one end being a fixed end and the other end being a movable end; and a switching element being located at the cantilever activity On the end, the switching element has a contact for generating a switching action after being pressed; the fixed end of the cantilever is fixed to a casing of an electronic product, and the electronic component is provided as a switch button by the other switching element. Since the switching element is disposed on the movable end of the cantilever, when the contact on the switching element is pressed, the resistance of the movable end of the cantilever is lower than the resistance of the contact on the switching element, so the movable end of the cantilever will be displaced but the switch When the component does not operate, the resistance of the contact of the switching element is less than the resistance of the active end, and then it is touched and generates a switching action; the cantilever design described above can be realized at a low cost, and is suitable for low-order electronic products. Anti-shake function.

Referring to a first embodiment of the present invention, the first embodiment is mainly composed of a cantilever (10) and a switching element (20). In this embodiment, the cantilever (10) is elongated. The plate shape may be made of metal or plastic, and has an elastic member that is relatively curved and automatically reset at both ends due to the elongated shape; based on the above characteristics, the present invention makes the end of the cantilever (10) a fixed end (11). For mounting purposes, the cantilever (10) is a movable end (12) opposite the other end, and the switching element (20) is provided on the movable end (12).

The completion, so that the resistance of the cantilever (10) movable end (12) is lower than the contact point (21) on the pressing switch element (20) to cause the resistance of the switching action, which means the activity of the cantilever (10) When the end (12) is pressed, the cantilever (10) will be deformed before the switching element (20) generates a switching action to extend the stroke of the switching element (12) from being triggered to actually generate the switching action, and in the stroke Fully absorb the hand vibration generated when the user touches the button.

The aforementioned button anti-shock structure is mainly used in various camera devices, such as digital cameras, digital cameras, network cameras, camera phones, and other portable electronic devices with camera functions. A possible implementation is further as follows: Still referring to the first figure, the button anti-shock structure of the present invention is installed in the casing (30) of any of the foregoing image capturing devices, the casing (30) is provided with a button (31) which can be pressed down by pressing. In this embodiment, a button hole (32) is formed in the casing (30) for the button (31) to be accommodated therebetween. And the upper end of the button (31) protrudes beyond the casing (30); it is understood by those of ordinary skill in the art that the button (31) is not necessarily in the aforementioned form, and the button on the casing (30) The hole (32) is also not necessarily present, and the button (31) may be a film construction that directly forms a microprojection on the casing (30) for depressing.
