SIGHTING APPARATUS CAPABLE OF DISPLAYING MAGNIFICATION
Provided is a sighting apparatus capable of displaying a value of magnification. The sighting apparatus includes a magnification generation module, a controller and a display unit. The magnification generation module includes a magnification pattern, which contains multiple values of magnification, and a sensing unit. When the magnification pattern is rotated, the sensing unit detects one of the magnification values from the magnification pattern. The magnification generation module generates a magnification signal corresponding to the magnification value. The controller functions to transform the magnification signal and the display unit displays the value of magnification corresponding to the magnification signal.
1 . A sighting apparatus comprising:
a magnification adjustment module, which is operated for adjusting magnification of the sighting apparatus;
a magnification generation module, which comprises a magnification pattern, which undergoes a movement in response to the operation of the magnification adjustment module, and a sensing unit, which detects the magnification pattern to obtain a current value of the magnification and generates a magnification signal corresponding to the current magnification value; and
a display unit, which displays the current magnification value corresponding to the magnification signal.
2 . The sighting apparatus as claimed in claim 1 , wherein the magnification pattern comprises a plurality of magnification sections, each corresponding to a value of the magnification.
3 . The sighting apparatus as claimed in claim 2 , wherein the magnification pattern and the magnification adjustment module synchronously movable with each other.
4 . The sighting apparatus as claimed in claim 3 , wherein the magnification adjustment module comprises a rotatable magnification adjustment ring.
5 . The sighting apparatus as claimed in claim 2 , wherein each of the magnification sections comprises a plurality of electrode zones.
6 . The sighting apparatus as claimed in claim 5 , wherein the sensing unit comprises a plurality of electrically conductive portions, which is in electrical engagement with respective electrode zones of the magnification sections so that the electrode zones detect the magnification signal.
7 . The sighting apparatus as claimed in claim 5 , wherein the magnification pattern comprises an electrically conductive ring.
8 . The sighting apparatus as claimed in claim 2 , wherein each of the magnification sections comprises a plurality of light/shade areas.
9 . The sighting apparatus as claimed in claim 8 , wherein the sensing unit comprises a plurality of light detection elements respectively corresponding to the light/shade areas of each magnification section so that the light detection elements detect the magnification signal.
10 . The sighting apparatus as claimed in claim 9 , wherein the magnification pattern comprises a disc-shaped layer of material.
11 . The sighting apparatus as claimed in claim 9 , wherein the magnification pattern comprises a rectangular layer of material forming a circumferential ring of pattern.
12 . The sighting apparatus as claimed in claim 1 further comprising a controller coupled to the magnification generation module for transformation of the magnification signal.
