DETAILED DESCRIPTION OF EXEMPLARY EMBODIMENTS
A detailed explanation of a digital camera according to an exemplary embodiment of the present invention will now be made with reference to the drawings attached hereto.
Referring to FIGS. 1A, 1B, 1C and 2, a digital camera 100 according to an embodiment is shown. The digital camera 100 includes a housing 10, a locating post 11, a rotatable assembly 12, an elastic element 13, a contact sheet 14, a pivot release 15, and a shutter button 16. FIGS. 1A-1C show the rotating assembly 12 of a digital camera 100 first in a right-hand operation position, then being rotated to a left-hand operation position, and finally in the left-hand operation position.
The housing 10 is configured for holding and protecting camera components, such as, a touch screen, a lens assembly, and so on therein.
The digital camera 100 includes a focusing circuit, an exposure assembly, a zoom code input circuit, a main circuit board, and a central processing unit (CPU) (not shown). These electronic elements, such as the focusing circuit, the exposure assembly, are mounted on the main circuit board. The CPU is electronically connected to the focusing circuit, the exposure assembly, and the zoom code input circuit, and performs general various operations of the digital camera, such as photometering, automatic focusing (AF) etc. The CPU carries out a predetermined operation in response to usage of the shutter button 16 and the exposure assembly.
The locating post 11 is fixed to the housing 10 and configured for locating the rotatable assembly 12, the elastic element 13, the contact sheet 14, and the pivot release 15.
Referring also to FIG. 3 and FIG. 4, the rotatable assembly 12 includes a base 120, a cover 121 covering the base 120, and a circuit board 122. The base 120 defines a base hole 123 therein for passage of the locating post 11 and the pivot release 15. The base hole 123 includes a main opening 124 and two branch slots 125 respectively extending from two opposite sides of the main opening 124. The locating post 11 passes through the main opening 124. The cover 121 includes a cover base 1211, a sidewall 1212 integrally formed with the cover base 1211, a cover hole 1213 defined in the base 1211, and a shutter opening 1214. The sidewall 1212 is perpendicular to the cover base 1211 and forms a receiving chamber (not labeled) together with the cover base 1211 and the base 120 for containing the circuit board 122. The cover hole 1213 is configured for passage of the locating post 11. The shutter opening 1214 is configured for passage of the shutter button 16. The circuit board 122 is interposed between the base 120 and the cover 121, and has a pad 126 configured for electronically contacting with the shutter button 16 to trigger the exposure assembly. The rotatable assembly 12 may be fixed to the housing through some conventional method known in the art, such as screws 129, when the position of the shutter button 16 is determined.
The elastic element 13 may be a coil spring and wraps around a portion of the locating post 11 thereby pushing the contact sheet 14 along the locating post 11 to a predetermined position.
The contact sheet 14 is interposed between the elastic element 13 and the pivot release 15 and includes a body 141 and two spring fingers 142 respectively extending from two opposite sides of the body 141. The body 141 and the two spring fingers 142 have different planes for tilting towards the pivot release 15. Generally, the two springs fingers 142 are respectively received in the two branch slots 125 of the base 120 and electrically contact with the circuit board 122. Once the pivot release 15 presses the body 141 of the contact sheet 14 downwardly, the two spring fingers 142 are disengaged from the circuit board 122. Thus, the rotatable assembly 12 can be rotated to change the location of the shutter button 16. The contact sheet 14 also include an opening 143 for passage of the locating post 11 and at least one locating hole 144 for locating the contact sheet 14 in cooperation with the pivot release 15. In the present embodiment, the contact sheet 14 includes two locating holes 144.
Referring also to FIG. 5, the pivot release 15 caps the locating post 11 and includes a cylinder-shaped portion 151, a pressing portion 152 connected to the cylinder-shaped portion 151, and two protruding pins 153. The cylinder-shaped portion 151 passes through the cover hole 1213 and the main opening 124 of the base hole 123, and contacts the body 141 of the contact sheet 14. The pressing portion 152 including an enlarged portion 154 and a narrow portion 155 connected to the enlarged portion 154. The dimension of the enlarged portion 154 is greater than that of the cover hole 1213 and the main opening 124 such that the enlarged portion 154 can be clamped and contained between the base 120 and the cover 121 to locate the pivot release 15. The two protruding pins 153 have a greater length than that of the cylinder-shaped portion 151 and are inserted into the corresponding locating holes 144 for further locating the contact sheet 14.
The shutter button 16 can be either left side or the right side of the camera via rotatable assembly 12 for right-handed of left-handed users to use. The shutter button 16 is electronically connected to a shutter of the lens assembly. When the shutter button 16 is located at the left side of the digital camera 100, it is convenient for left-handed users to operate the digital camera 100 and when it is at the right side of the digital camera 100, the shutter button 16 is convenient for right-handed users to operate.
As described above, the rotatable assembly 12 may help users to select one of the left side and the right side of the digital camera 100 as desired for left-handed or right-handed operation of the digital camera 100.
It should be understood that the above-described embodiments are intended to illustrate rather than limit the invention. Variations may be made to the embodiments without departing from the spirit of the invention. Accordingly, it is appropriate that the appended claims be construed broadly and in a manner consistent with the scope of the invention.
