Description

[Detailed description of the invention]

[0001]

[Industrial applications]

 The present invention relates to a scanner that integrates an automatic sheet feeding type scan and a flatbed type scan.

[0002]

[Prior art]

 At present, the type of scanner is determined according to the scanning range and the size required by the user.For example, when the scanning range is relatively large, a flatbed scanner is automatically supplied without the need for portable, space-saving. If you want to be able to do paper, choose an upright scanner. A flatbed and upright dual-integrated scanner with the ability to scan larger areas and automatically feed paper to the flatbed scanner is now available. You can now choose. However, since the flatbed optical scanning parts are provided below the transparent plate of the flatbed main body and the automatic paper feeder is provided on one upper side of the flatbed main body, the automatic paper feeder occupies the scan range portion of the flatbed main body, The paper feeder can only feed single-sheet paper, and the automatic paper feeder that inserts paper cannot feed the paper stably.After the paper is caught between the rollers, the paper must be fed by the roller. If there is an error, the scanning quality of the entire paper cannot be assured, and it is necessary to add an extension structure before being caught by the rollers. Since the paper feed is stabilized by the support of the extension structure, the dust prevention lid of the automatic paper feeder is currently extended, but the extension of the dust prevention lid is not long enough to achieve the expected effect. Is impossible.

[0003]

[Problems to be solved by the invention]

 An object of the present invention is to improve a scanner structure having an automatic paper feed type scan and a flatbed type scan function.In particular, the extension structure of the automatic paper feed type scan is strengthened, and the feeding stability is improved. The main feature is that it has the effect of continuously feeding paper at the same time, and when switching to flatbed scanning, the scanning space of the flatbed body is not occupied by the addition of an automatic paper feeder. Another object of the present invention is to integrate an opaque reading structure and a transparent reading structure, and is characterized by changing a current single-function scanner. Still another object of the present invention is for a case where the paper is fed to the scanner and the paper is jammed.However, due to the design of the one-way bearing in the transmission system, the directly jammed paper is pulled back in the direction opposite to the inserting direction. Resolve the jam.

[0004]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, the improvement of the scanner structure of the present invention is to provide an automatic paper feeder at a position where the flat base body and the lid of the scanner are connected to each other, and to connect the automatic paper feeder with the lid and the flat base body. The separation method is set by a changeover switch provided on the lid. In other words, when the user sets the lid as an extension tray for continuous paper feeding, when the changeover switch is switched to the automatic paper feeding type scan, the automatic paper feeding device is fixed on the flat base body, the lid is separated, and the lid is separated. When opened, the dust-proof lid of the automatic paper feeder is raised at the same time, and the automatic paper feeder can perform stable continuous paper feeding. Also, when the changeover switch is set to a flatbed type scan, the automatic paper feeder is separated from the flatbed main body and integrated with the lid, so that when the user opens the lid, the automatic paper feeder is lifted together with the lid. Therefore, by providing a scan space to the main body of the flat base and expanding the scan range, it is possible to achieve the dual effect of continuous feed automatic scan and expansion of the flat base type scan range. In addition, the present invention has a reflection type reading function as described above, and can also read a transparent type.However, in order to achieve the latter effect, a transparent plate through which a light emission source is passed is particularly provided on the inner surface structure of the lid. Measure and allow light to pass through a transparent one, creating a scan reading effect. At the same time, the scanner of the present invention has a one-way bearing in the paper feed transmission system to eliminate the risk of paper jams during scanning and reading.If a paper jam occurs, pull back in the paper insertion direction and pull the scanner back. Solve the problem without opening it.

[0005]

[Embodiment of the invention]

 FIGS. 1 to 6 show an embodiment of the present invention. A scanner 10 according to this embodiment is a combination of an automatic sheet feeding type scan and a flatbed type scan structure, and is integrated on a flatbed body 11. A transparent plate 111 is provided for convenient scanning by placing paper on the transparent plate 111. On both upper sides of the outer edge of the transparent plate 111, cut grooves 112 are provided, respectively. Is provided with a cutout, and the lid 12 to which the two shaft arms 122 and 122 are attached is connected by a shaft. The lid 12 can be opened and closed because its two shaft arms 122 and 122 are connected by the main shaft 121 on the flat base body 11, and at the same time, a transparent plate provided with a light emitting source is provided inside the inner surface of the lid 12. This makes it possible to scan and read transparent ones (eg, positive and negative films, slides, X-ray films, etc.), adding selectivity and functionality as a scanner to read opaque ones. Next, the automatic paper feeder 20 is connected near the cut end of the lid 12 by a shaft. The point of the automatic paper feeder 20 is that it is connected to the shaft arms 122 and 122 of the lid 12 by the first shaft 21, and the first shaft 21 is controlled by the main shaft 121 by contacting the main shaft 121. The second shaft 22 provided in the automatic paper feeder 20 is in contact with the first shaft 21 and controls the opening and closing of the dust prevention cover 221 at the paper insertion opening of the automatic paper feeder 20. Further, a changeover switch 13 is provided on the side edge of the cut. The changeover switch 13 is a two-stage switch for selecting an automatic sheet feeding type scan or a flatbed type scan. The changeover switch 13 fixes the rotation of the interlocking shaft 131 to the rotating piece 132 below it. Then, a switching effect is created. That is, the rotating piece 132 pushes the symmetrical side and comes into contact with the protection piece 232 in the perforation of the automatic sheet feeding apparatus 20. The protective piece 232 is fixed on a shaft 23 attached to the other end of the automatic paper feeder 20, and hook portions 233 are provided at both ends of the shaft 23. When the rotating piece 132 of the changeover switch 13 pushes and opens the protection piece 232 by the elastic part 231 provided on the shaft 23, the automatic sheet feeding is fixed to the flat base body 11 cut groove 112 by the hook 233. The apparatus 20 leaves the flat base body 11 and is connected to the lid 12, so that a flat base scan is performed. As shown in FIG. 6, when the automatic sheet feeder 20 is opened together with the lid 12, the flat base body 11 is also opened, thereby expanding the scan plane range of the flat base body 11 (currently, A4 is regarded as the maximum range). Do). When the switch 13 of the flatbed type scan set above is changed to the automatic paper feed type scan and switched, when the rotary piece 132 of the switch 13 is returned to the original position, the protective piece 232 which presses the automatic paper feeder 20 is set. The elastic part 231 of the automatic sheet feeder 20 returns to its original shape, and the hook 233 is also fixed in the cut groove 112 of the flat base body 11. At this time, the automatic sheet feeding device 20 is separated from the lid 12 and is connected to the flat base body 11. Once the lid 12 is opened, the first shaft 21 of the automatic sheet feeder 20 rotates by receiving the movement of the main shaft 121, and indirectly transmits the movement to the second shaft 22, whereby the dust-proof lid 221 is opened. It is. In this way, the lid 12 is opened at the same time as the dust prevention lid 221, and the lid 12 serves as an extension tray for feeding the paper of the automatic paper feeder 20, supports the rear weight of the paper, and increases the stability during paper feeding. In addition to raising the height, it can place dozens of sheets of paper for scanning, creating the effect of continuous paper feed scanning.

As shown in FIG. 7, a transmission system 30 is for transmitting a movement exclusively for the automatic sheet feeder 20 to perform a scanning operation. In this transmission system, a motor 31 mainly moves a transmission rod 32. The other end of the transmission rod 32 is connected to the driving gear 33, and the driving gear 33 moves simultaneously with the transmission rod 32, and the internal gear 34 meshed with the outer edge of the driving gear 33 is controlled by the rotation of the driving gear 33. . A central gear 35 is provided at the center of the internal gear 34, and the central gear 35 moves a page feed gear 37 on the outer edge of the central gear 35, and a one-way bearing 371 is provided on the page feed gear 37 and a page feed roller 372 is provided. Connected and meshed with the outer edge of the page feed gear 37 is a page dividing gear 36, a one-way bearing 361 is attached to the page dividing gear 36, and the one-way bearing 361 is connected to a page dividing roller 362. . Once the object to be scanned is put into the page separation roller 362, the page separation page and the page separation roller 362 are used to separate the pages one by one, and then the scanning process is started. If a paper jam occurs during the paper feeding process, the difference from the traditional scanner is the operation of removing the jammed paper by opening the transmission system. The present invention has a structure in which one-way bearings 371 and 361 are provided on the page feed gear 37 and the page division gear 36, and both are controlled by the page feed gear 37 and the page division gear 36, and rotate only in one direction. . Once the rotation is stopped (for example, in the case of a paper jam), the page feed gear 37 and the page split gear 36 are both stopped, and the one-way bearings 371 and 361 are turned off when there is no power source. Then, the page separating roller 362 is rotated in the forward direction and the opposite direction. This allows the jammed paper to be pulled back in the opposite direction to the paper entry direction, a task that is limited in traditional scanners (easily breaking the transmission system), even in the case of a paper jam. However, the transmission system 30 of the present invention must not be opened or separated, and has the effect of quickly removing a paper jam as long as the jammed paper is removed.

[0007]

[Effect of the invention]

 (1) If the scanner that combines the automatic paper feed type and the flatbed type is switched and the setting is changed to the automatic paper feed scan type, the automatic paper feeder is hooked on the flat base body and fixed. Connect and separate the automatic paper feeder and lid at the same time. When the lid is opened, the dust prevention lid of the automatic paper feeder is simultaneously lifted, so that the lid and the dust prevention lid are opened at the same time. This not only adds the extra length required by the dust-prevention lid, but also increases paper feed stability and allows several tens of sheets of paper to be placed on the lid, increasing the effectiveness of continuous paper feed scanning. Spawn. (2) If the scanner is switched to flatbed scanning, the automatic paper feeder is separated from the flatbed body and connected to the lid. When the lid is opened, the automatic paper feeder rises with the lid. The automatic paper feeder that is hooked and fixed to a part of the scan area of the flat base unit returns the occupied scan area, and the present invention has a relatively large scan space compared to the conventional product. (3) In addition to being able to read opaque objects, the scanner of the present invention has the effect of reading transparent objects, and if a paper jam occurs, pull the paper back in the direction opposite to the paper feeding direction. It has the effect of quickly solving the problem.
