Description of the Invention: [Technical Field] The present invention relates to an automatic paper feeding device, and more particularly to an automatic paper feeding device provided with a document size detecting device. [Prior Art] A general automatic paper feeding device is used in conjunction with a scanning device. Since A4 size documents are most widely used, most of the automatic paper feeding device paper feed and paper output cassettes are specifically designed to be A4 size. In this case, there is no need to set the file size detecting device. In the case of an automatic paper feeding device that can feed A3 file size, in addition to the larger A3 size document, the A4 size document can also be fed using the horizontal feeding method, and the scanning size is twice the size of the A4 size. In this case, it is necessary to set a file size detecting device to determine whether the file to be scanned is A4 size or A3 size. Of course, file size detection will also be required in the case of scanning such as A5, B4, and B6. Taiwan Patent No. 588545 proposes a document size detecting device with an automatic paper feeding device. Please refer to the first figure, which is a schematic diagram of the file size detecting device and the automatic paper feeding device of the Taiwan Patent Publication No. 588545. A first paper guide 14 and a second paper guide 16 are disposed on both sides of the paper feed 10 of the automatic paper feeding device, and the first paper guide 14 and the second paper guide 16 are movable to be close to or away from each other, the paper tray 1 The paper has a paper placement surface 13 on which the document is placed, wherein the first paper guide 14 and the second paper guide 16 protrude from the front surface 13 of the first surface. Further, the back surface of the paper insertion surface 13 is defined as the bottom 15 of the paper feed cassette 1 , and a document size detecting device 20 is further disposed at the bottom 15 of the paper feed cassette 1 . 5 1333931 Please refer to the second figure, which is a schematic diagram of the document size detecting device 2 of the Taiwan Patent Publication No. 588545, including the sensing element and the plurality of ribs 42. The document size reading device module 30 disposed on the bottom portion 15, the first channel 33, the second channel 35, and the third channel 37
且凸肋42可隨著第一導紙器14而移動。感應元件模組如又包括第一 感應元件組32、第二感應元件組34以及第三感應元件虹36，其中第 一感應元件組32由第一感應元件32A、32B所組成且第—通道33位 於第一感應元件32A與32B之間，第二感應元件組34由第二感應元 件34A、34B所組成且第一通道35位於第二感應元件34a與34B之間 第三感應元件組36由第三感應元件36A ' 36B所組成且第三通道37 位於第三感應元件36A與36B之間。 當不同尺寸之文件（未標示於圖中）被放置於進紙匿1〇(如第一圖中 所示）上時，第一導紙器14以及第二導紙器16會根據文件之尺寸而移 動至使文件可平坦地被放置於進紙匿.10上之位置，此時，第一導紙器 14 一移動，複數凸肋42也會隨其移動，因應文件尺寸之不同，第一 導紙器14之位置不同，複數凸肋42之位置也隨著不同，再加上複數 凸肋42與複數通道之位置會產生複數種情況，而習知文件尺寸偵測裝 置20(如第一圖中所示）是根據凸肋42是否進入通道内之複數種情況來 判斷文件之尺寸。 。疋義通路狀態之數位訊號為邏輯1以及斷路狀態之數位訊號為邏 輯〇並將此定義設定於文件尺寸判斷裝置20中。當複數凸肋42皆未 進入第一通道33、第二通道35以及第三通道37内時，也就表示第一 忍'、元件.，且32、第一感應元件組μ以及第三感應元件組36未被凸肋 2所阻隔而皆呈現通路狀態，因此文件尺寸判斷裝置20則獲得三個 位元的之數位訊號，即「111」。 i 6 1333931 當第一感應元件組32被凸肋42阻隔而呈現斷路狀態，第二感應 元件組34以及第三感應元件組36未被凸肋42所阻隔而皆呈現通路狀 態，文件尺寸判斷裝置20獲得之三個位元之數位訊號為「〇11」。以此 類推，共產生8(2的三次方)種情況，故可判斷8種文件尺寸。雖然如 此，但習知文件尺寸判斷裝置2〇的結構太過複雜，並且另外需要定義 二個位兀之數位訊號代表何種文件尺寸，不僅是結構上複雜，數位電 路系統也太過複雜，實不符合經濟效應。 【發明内容】 本發明之目的在提供一種具有文件尺寸偵測裝置之自動饋紙裝置，特 別是關於-種具有簡單結構之文件尺寸偵測裝置之自動饋紙裝置。 • 於—難實施财，本發明提出-種具有文件尺寸制裝置之自動績紙 裝置’自動饋紙裝置包括—進紙E用以放置文件於其上，特徵在於自動饋 紙裝置包含文件尺寸偵測裝置，且文件尺寸_裝置包括： 鲁 第一導紙板，包括： 第一擋紙片’用以固定文件於進紙g之表面上； 第-齒條’設置於進紙£之底部；以及 肋片，設置於進紙匣之底部； 第二導紙板，包括： 第二擋紙片，用以固定文件於進紙臣之表面上；以及 第二齒條’設置於钱g之底部； 第長升v穿孔位於進紙昆上，且第一導紙板穿過第一長形穿孔，使得 i 7 1333931 第一擒紙片位於進紐之表面上，且第一齒條及肋片係位於進難之底部； 第二長形穿孔，位於進紙m導紙板穿過第二長形穿孔，使得 第二擔紙片位於進紐之表面上，且第二齒條係位於進紙£之底部； 齒條移動裝置，用以與第-齒條以及第二齒條屬合而使第一以及第二導 紙板分別於第一以及第二長形穿孔中移動；以及 複數感測裝置，設置於進紙£之該底部，每一感測裝置具有一光發射器 以及-光接收器，其中藉由移動第-導紙板使肋片被移動至光發射器與光 •接收器之間。 於一較佳實施例中，第一導紙板中之第一擋紙片、第一齒條以及肋片 係一體成型。 於—較佳實施例中’第二導紙板中之第二擋紙片以及第二齒條係一體 成型。 • 於—較佳實施例中，齒條移動裝置包括一齒輪、一轉盤以及一轉軸。 8 1333931 【實施方式】And the rib 42 can move with the first paper guide 14. The sensing element module further includes a first sensing element group 32, a second sensing element group 34, and a third sensing element rainbow 36, wherein the first sensing element group 32 is composed of the first sensing elements 32A, 32B and the first channel 33 Located between the first inductive elements 32A and 32B, the second inductive element group 34 is composed of the second inductive elements 34A, 34B and the first channel 35 is located between the second inductive elements 34a and 34B. The three sensing elements 36A' 36B are formed and the third channel 37 is located between the third sensing elements 36A and 36B. When documents of different sizes (not shown in the figure) are placed on the paper feed (as shown in the first figure), the first paper guide 14 and the second paper guide 16 are moved according to the size of the document. So that the document can be placed flat on the paper feed. 10, at this time, as the first paper guide 14 moves, the plurality of ribs 42 also move with it, and the first paper guide 14 is adapted to the file size. The position of the plurality of ribs 42 is different, and the position of the plurality of ribs 42 and the plurality of channels may generate a plurality of cases, and the conventional document size detecting device 20 (as shown in the first figure) The size of the document is judged based on a plurality of cases in which the rib 42 enters the channel. . The digital signal of the state of the ambiguous path is logic 1 and the digital signal of the open state is logical 〇 and this definition is set in the file size judging device 20. When the plurality of ribs 42 do not enter the first channel 33, the second channel 35, and the third channel 37, it also represents the first end, the component, and 32, the first sensing element group μ, and the third sensing element. The group 36 is not blocked by the rib 2 and assumes a path state, so the file size judging device 20 obtains a digit signal of three bits, that is, "111". i 6 1333931 when the first sensing element group 32 is blocked by the rib 42 to assume an open state, the second sensing element group 34 and the third sensing element group 36 are not blocked by the rib 42 and are in a path state, and the file size judging device The digital signal of the three digits obtained by 20 is "〇11". By analogy, a total of 8 (2 cubics) is generated, so eight file sizes can be determined. However, the structure of the conventional file size judging device 2 is too complicated, and in addition, it is necessary to define two bits of the digital signal to represent the file size, which is not only structurally complicated, but also the digital circuit system is too complicated. Not in line with economic effects.

Please refer to the seventh figure, which is a structural diagram of a bottom view of a document size detecting device according to another preferred embodiment of the present invention. In the preferred embodiment, the document size measuring device 1 1 can identify three file sizes - A3 size, A4 size, and A5 size. Therefore, three sets of sensing devices are required to detect the A3 size first sensing device 180, respectively. (including the first light emitter 18〇1 and the first light receiver 1802), the second sensing device 丨8丨 detecting the A4 size (including the second light emitter 1811 and the second light receiver 1812) and the Detector Measuring the third sensing of the A5 size 11 1333931 device 182 (including the third light emitter 1821 and the second light receiver 1822), the situation of the first sensing device 180 of the size of the A] has been proposed in the above paragraph, so This supplement explains the case of the 8 4 size and the A5 size. When you want to set the second sensor for detecting the A4 size file, the device 181, the first guide paper 120 and the second paper guide (not shown in the figure) The distance between the two is adjusted to a file width equivalent to A4 size, about 21 mm, and the second sensing device 181 must be placed slightly below the position of the rib 12〇3 of the first paper guide 丨2〇' The ribs 1203 are located at the second light emitter 1811 and the second light receiver 丨 812 Room. The same applies to the sensing device 182. The distance between the first paper guide 120 and the second paper guide (not shown) is equal to the width of the document corresponding to A5R inch, 228 mm, The second sensing device 182 is disposed slightly below the position of the ribs 12〇3 of the first paper guide 12, such that the ribs 1203 are located between the third light emitter 1821 and the third light receiver. The seven figures are shown. The invention relates to an automatic paper feeding device with a reading size device which improves the highly complicated structure of the prior art and the digital circuit system. The invention only needs to provide a rib on the bottom of the paper guide to block the light beam. The size of the document is known by the optical receiver being unable to receive the beam. There is no need to call the multiple channels of the technology and only one path for the ribs to pass through, and the device on the path can be set to detect more files of different sizes instead of being limited to a fixed number of The size of the cow can easily change the setting position of the sensing device according to the user's needs, providing the user with a larger (four) miscellaneous M and selectivity. Correctly, the present invention only needs to determine the size of the file according to which the light receiver does not have a beam of light, and does not require a digital circuit such as the prior art. It is a simplification of the complexity of the prior art. It is only a preferred embodiment of the present invention, and is not intended to limit the scope of the application of the present invention. Equivalent to 12 1333931 variants or modifications shall be included in the scope of the patent application in this case.
