At the time when the paper document is fed into the inner portion of a printer or a copier, the printer or the copier detects the width of the paper document. According to the width of the paper document, the printer or the copier selects the print paper with a suitable size from a paper input tray. Then, the contents of the paper document are printed out and printed on the print paper.
- Conventionally, the sensors for measuring the paper width paper are installed within the paper input platform of the printer or the copier. For example, the sensors are infrared sensors, pressure sensors or any other appropriate optical sensors. Since sensors are power-consuming, the printer or the copier has to provide a lot of electric power to the sensors. For allowing the sensors to successfully detect the paper width, the problem of wasting electric power occurs.
- Moreover, since the sensors are installed within the paper input platform of the printer or the copier, the paper input platform needs to have the corresponding structures for installing the sensors. Generally, the sensors are only able to detect limited number of paper width sizes. For accurately detecting different paper width sizes, it is necessary to install many sensors within the paper input platform. Under this circumstance, the inner structure of the paper input platform is complicated. Moreover, since the sensors are bulky, the sensors occupy much inner space of the paper input platform.

FIG. 4 is a schematic perspective view illustrating the paper size detection module in a usage state according to an embodiment of the present invention. Firstly, the user places apaper 80 on thepaper support plate 91. Then, thepaper positioning block 21 is moved in the direction toward thepaper 80. Correspondingly, the slidingtrack 22 is moved in the direction toward thepaper 80. Due to the engagement between the slidingtrack 22 and theratchet 26, theratchet 26 is correspondingly rolled. As theratchet 26 is rolled, the linked slidingtrack 28 is correspondingly moved in the direction toward thepaper 80. As the linked slidingtrack 28 is moved, the linkedpositioning block 27 is moved in the direction toward thepaper 80 until thepaper positioning block 21 and the linkedpositioning block 27 are respectively contacted with the two edges of thepaper 80. While thepaper positioning block 21 is moved in the direction toward thepaper 80, the slidingtrack 22 is moved and theroller 23 is rolled with the movement of the slidingtrack 22. Consequently, theroller 23 is rolled along thecarrier plate 11 and the pressed surfaces 141. When thevertical positioning plate 212 of thepaper positioning block 21 is contacted with thepaper 80 and a specified pressedsurface 141 is pressed by theroller 23, theelastomer 14 corresponding to the specified pressedsurfaces 141 provides a force or a pressure to thesensing circuit board 12. According to the position of theelastic element 14 which provides the force or the pressure, thesensing circuit board 12 generates a paper size signal. That is, when the position of the pressedsurface 141 pressed by theroller 23 is detected by thesensing circuit board 12, thesensing circuit board 12 generates the corresponding paper size signal. After receiving the paper size signal from thesensing circuit board 12, the printer or the copier calculates the width size of thepaper 80. Then, According to the width size, the printer or the copier selects the print paper with a suitable size from a paper input tray. Then, the contents of the paper document are printed out and printed on the print paper. - Since the width of the
paper 80 is calculated according to the result of detecting the position of the pressedelastomer 14 by thesensing circuit board 12, it is not necessary to additionally install position sensors within the printer or the copier to detect the paper width. Consequently, the paper size detection module achieves the benefits of simplifying the structure, reducing the structural cost, saving the material cost and saving the structural space. Since thesensing circuit board 12 cooperates with theroller 23 and theelastomers 14 to detect the paper width, it is not necessary to additionally install sensors and the power-saving purpose is achieved. Moreover, as long as the number of theelastomers 14 is increased, the range of the paper width size can be expanded. - As mentioned above, the
elastomers 14 are protruded from theresilience plate 13, and theresilience plate 13 is clamped between thesensing circuit board 12 and thecarrier plate 11. Consequently, when theelastomers 14 are pressed by theroller 23, theelastomers 14 are not shifted. Under this circumstance, theelastomers 14 are not detached from theperforations 111 of thecarrier plate 11. - As mentioned above, the sliding
track 22 is supported by the ring-shaped raisedstructure 261 of theratchet 26. Consequently, while the slidingtrack 22 is moved, the slidingtrack 22 is continuously moved along the same horizontal line. In other words, the slidingtrack 22 is not moved aslant. - From the above descriptions, the paper size detection module of the present invention has the following features. Firstly, the
position sensing assembly 10 and the slidingblock assembly 20 are used to achieve the function of detecting the width size of thepaper 80. Secondly, since the information about the width size of thepaper 80 is realized according to the result of detecting the position of the pressedelastomer 14 by thesensing circuit board 12, the paper size detection module can achieve the benefits of simplifying the structure, reducing the structural cost, saving the material cost and saving the structural space. Thirdly, since theresilience plate 13 is clamped between thesensing circuit board 12 and thecarrier plate 11, theelastomers 14 are not shifted. - While the invention has been described in terms of what is presently considered to be the most practical and preferred embodiments, it is to be understood that the invention needs not be limited to the disclosed embodiments. On the contrary, it is intended to cover various modifications and similar arrangements included within the spirit and scope of the appended claims which are to be accorded with the broadest interpretation so as to encompass all modifications and similar structures.
