Object loading apparatus having pressing cam for controlling inclination of object loading plate and image processing apparatus having the object loading apparatus implemented therein

Abstract

The present invention provides an object loading apparatus, including: an elastic component positioned at a bottom plate of an object feeding device; a first pivot positioned at a side plate of the object feeding device; an object loading plate rotatably coupled to the first pivot for loading objects, wherein the elastic component provides an elastic force to the object loading plate to rotate the object loading plane; a second pivot positioned at a side plate of the object feeding device; a pressing cam rotatably coupled to the second pivot; and a guiding module coupled to the pressing cam for rotating the pressing cam to make an inclination of the object loading plate of the object feeding device when the object feeding device is at an object feeding position smaller than an inclination of the object loading plate when the object feeding plate is at an object loading position.

1 . An object loading apparatus, comprising:
 an elastic component, positioned at a bottom plate of an object feeding device;   a first pivot, positioned at a side plate of the object feeding device;   an object loading plate, rotatably coupled to the first pivot, for loading objects, the object loading plate further contacting with the elastic component, wherein the elastic component provides an elastic force to the object loading plate to rotate the object loading plate around the first pivot;   a second pivot, positioned at a side plate of the object feeding device;   a pressing cam, rotatably coupled to the second pivot; and   a guiding module, coupled to the pressing cam, for rotating the pressing cam to make an inclination of the object loading plate of the object feeding device when the object feeding device is at an object feeding position smaller than an inclination of the object loading plate when the object feeding device is at an object loading position.   
   
   
       2 . The object loading apparatus of  claim 1 , wherein when the object feeding device is positioned at the object feeding position, the guiding module guides the pressing cam to rotate to a first position in order to allow the elastic component to rotate the object loading plate for making the object loading plate inclined accordingly; and when the object feeding device is positioned at the object loading position, the guiding module guides the pressing cam to rotate to a second position in order to stop the elastic component from rotating the object loading plate so the object loading plate is in a horizontal position. 
   
   
       3 . The object loading apparatus of  claim 1 , being applied in an object processing apparatus, wherein the guiding module is a guiding fillister positioned on an apparatus side plate of the object processing apparatus; and a sliding terminal of the pressing cam is movably coupled to the guiding fillister in order to rotate the pressing cam around the second pivot when the object feeding device is moving. 
   
   
       4 . The object loading apparatus of  claim 3 , wherein the object processing apparatus is a printer, a Photostat, or a multi-function printer. 
   
   
       5 . The object loading apparatus of  claim 3 , wherein the elastic component is coupled to the bottom plate of the object loading plate; a first predetermined position of the guiding fillister is not a same height as a second predetermined position of the guiding fillister; when the object feeding device is positioned at the object feeding position, the sliding terminal of the pressing cam is moved to the first predetermined position; and when the object feeding device is positioned at the object loading position, the sliding terminal of the pressing cam is moved to the second predetermined position. 
   
   
       6 . The object loading apparatus of  claim 1 , wherein the object feeding device is a paper feeder. 
   
   
       7 . An image processing apparatus comprising:
 an object feeding device, comprising:
 an elastic component, positioned at a bottom plate of the object feeding device; 
 a first pivot, positioned at a side plate of the object feeding device; 
 an object loading plate, rotatably coupled to the first pivot, for loading at least one sheet of medium, the object loading plate further contacting with the elastic component, wherein the elastic component provides an elastic force to the object loading plate to rotate the object loading plate around the first pivot; 
 a second pivot, positioned at a side plate of the object feeding device; and 
 a pressing cam, rotatably coupled to the second pivot; and 
   a housing having a cavity for accommodating the object feeding device, and a guiding module, coupled to the pressing cam, for rotating the object loading plate while the object feeding device is moved between an object feeding position and an object loading position.   
   
   
       8 . The image processing apparatus of  claim 7  further comprising a pickup roller disposed above the object loading plate. 
   
   
       9 . The image processing apparatus of  claim 8  wherein the object loading plate is rotated toward the pickup roller while the object feeding device is moved from the object loading position to the object feeding position. 
   
   
       10 . The image processing apparatus of  claim 9  wherein the loaded medium adjoins the pickup roller while the object feeding device is moved to the object feeding position.
