Indication structure for paper reserves adapted for auto document feed apparatus
View Patent ↗An indication structure for paper reserves adapted for auto document feed apparatus includes a housing, a feed module, a printer module, a support element, an elasticity element, a light source, a shield element and a transparent element; wherein, the shield element is arranged on a radiation path of the light source, to shield the part of light, the transparent element is mounted in an opening of the housing, for providing the light radiated out. Whereby, using the simple structure to improve higher manufactured cost, processes and longer time of fabrication.
1. An indication structure for paper reserves adapted for an auto document feed apparatus having a housing, at least one opening arranged thereon, a support element received in the housing, an elasticity element fixedly positioned between the housing and the support element, to contact with the support element elastically; the indication structure for paper reserves, comprising:
a light source received in the housing to radiate light; and
a shield element arranged on a radiation path of the light source to shield a part of the light;
whereby the paper reserves are indicated though the light obvious from the opening.
2. The indication structure as claimed in claim 1 , wherein the light source is a light emitting diode (LED).
3. The indication structure as claimed in claim 1 , wherein the shield element is the paper.
4. The indication structure as claimed in claim 1 , wherein the shield element is a non-transparent element.
5. The indication structure as claimed in claim 4 , wherein the non-transparent element is a plate with a protrusion to contact with the support element.
6. The indication structure as claimed in claim 1 , further comprising a transparent element is mounted on opening for observing.
7. The indication structure as claimed in claim 6 , wherein the transparent element is a piece of optical transparent plastic or optical glass.
8. An indication structure for paper reserves adapted for an auto document feed apparatus, comprising:
a light source received in a housing of the auto document feed apparatus to radiate light; and
a shield element arranged on a radiation path of the light source to shield a part of the light;
whereby the paper reserves are indicated though the light obvious from an opening on the housing.
9. The indication structure as claimed in claim 8 , wherein the light source is a light emitting diode (LED).
10. The indication structure as claimed in claim 8 , wherein the shield element is paper.
11. The indication structure as claimed in claim 8 , wherein the shield element is a non-transparent element.
12. The indication structure as claimed in claim 11 , wherein the non-transparent element is a plate with a protrusion to contact with a support element received in the housing.
13. The indication structure as claimed in claim 8 , further comprising a transparent element mounted on the opening of the housing for observing.
14. The indication structure as claimed in claim 13 , wherein the transparent element is a piece of optical transparent plastic or optical glass.
