TW555674B - Clamping mechanism for automatic document feeder - Google Patents

Abstract

A scanner includes a hook groove and an automatic document feeder. The hook groove is formed on one side of the scanner. The automatic document feeder is provided with a hook and a force application part. The hook is used to engage with the hook groove so that the automatic document feeder can mount to the scanner. When the force application part is acted upon by a force, the automatic document feeder can be separated from the scanner. The scanner further includes a guide slope and the guide slope is arranged above the hook groove. The hook engages the hook groove through the guide slope.

f Field of invention J The present invention is related to a kind of misplacement volume seeding of a kind of Yongtian a kind of automatic paper feeder, which is applied to the scanner from :: mechanism ', and especially the misfeed of moving paper. [Invention background j Hold machine M. The scanner is a green device such as a page, graphics, and illustrations. It is used to scan photos and texts and convert them to computer. Coins or textiles and other 3D objects can be edited, stored, and rotated. Μ shapes and photos 1 , For example: formula. Sweep the time, · put the straight order into the word processing software order, store in the narrative of the festival's tongue, and scan the file into the data block order to tell the whole person and: add lively and vivid in the multimedia order 2 library or word processing soft data makes it more effective to show the many advantages in the briefing, making the broadcaster cry. Violating the main idea. As far as the company is concerned, it becomes no; lacking ::: A computer user or a paper-feeding scanner that is a public machine is A-side and has an automatic paper feeding to be automatically and conveniently fed into the scanner, only To be scanned-the speed of the scanner to scan documents can be more quickly detected on the platform. The working principle of the Yibei and My scanners is that the document to be scanned is stored in the scanner by the moving feeder: placed on the scanner The relative movement between the self-document and the optical module makes the reflection mode \ 2 & the light source module receive this reflected light signal after the second f is irradiated on the document to be scanned, and then converted into electricity. After π, optical tracing is performed. Electric alum treatment to complete the sweep

The document to be scanned is related to the light wind 2 image: quality, which has a decisive depth, and it is also related to the optical path length; ΐ: the distance between modules (that is, the scene's property = constant value, so that the scanned image has an appropriate value) And, the J scanner most urgently needed & Bai Xuer, if there is a better kind of connection between the feed: and there is a proper gap between the feeder and the optical module of the scanner Let the document to be scanned and [inventive purpose and summary] be here, the purpose of the present invention is to hold and have a suitable automatic paper feeder. Reverse ", has a proper and fixed depth of field The purpose of this book is: to propose a kind of automatic paper feeder holding machine with a card 2 to 2 arranged on the side of the scanner. The automatic paper feeder it holder can be linked with the 'drawi': : The hook groove is known to be connected, so that the automatic paper feeder and the scanner are scanned: :: r: rr = Automatic feed guide, and from the & The above 'card hook system can be more clearly and easily through the guide slope and hook groove characteristics, and advantages, and in accordance with the drawings, make In order to make the fine that the above object of the present invention to understand, several preferred embodiments of a clear hereinafter follows.] Out the preferred embodiment of the present invention, the holding mechanism provided in the automatic sheet feeder, with a system using

555674 V. Description of the invention (3) The hook on the moving paper feeder is connected to the hook groove on the scanner, so that the automatic paper feeder can be fixed on the scanner effectively. And because of this kind of fixed side: Scan :: to an appropriate and fixed scene and depth to improve the scanned image ^ According to Figure 1A ', it is shown in accordance with the preferred embodiment of the present invention to move the feeder A perspective view of the scanner. 3 of the automatic feeder 100 includes a hook 11 and a biasing portion 120. The scanner 130 has guide slopes 140 and hook grooves 150 on both sides. ’The automatic feeder 100 and the scanner 130 were originally separated. The combination of the self-feeder 100 and the scanner 130 is achieved by pressing the automatic feeder 100 so that the hook 110 can be lowered along the guide inclined surface 14 with an inclined angle and the hook groove 15 below the guide inclined surface 140 ( ) Are linked and combined. During the downward movement of the hooks 10 and 10 along the guide slope 14, the hooks 0 are gradually opened slightly as the downward displacement increases. When the hook hook no slides to the hook groove 150, the hook hook 110 firmly grasps the hook groove 150, so that the automatic feeder 100 and the scanner 130 are combined together. The urging part 12o on the automatic paper feeder 100 has a function 1 for detaching the automatic feeder ho from the scanner uo. 1 That is, pressing the urging part 12o by force, 2 can cause the hook 110 to be opened by force. The hook 100 opened by the force is no longer restricted by the restriction of the hook groove 150. At this time, if the force is raised again to raise the automatic feeder 100 ′, another automatic feeder 100 may be added. 13〇 detached. Please refer to FIG. 1B ′, which is a schematic cross-sectional view showing the separation of the automatic feeder and the scanner corresponding to FIG. U. What the automatic feeder 100 has

Description of the invention (4) The hook 11 0 is connected to the hook groove 150 of the scanner 130 through the guide bevel 140 and the automatic feeder 1 0 0 and Scanner 1 3 0 combined purpose. σ Figure 1C shows the schematic diagram of the hook 110 and the hook groove 150 after being connected. Figure 1D shows the schematic diagram of applying the force F to the force applying portion 120 to make the hook go out of the slot 150. Hook In the above-mentioned preferred embodiment, both the guide slope 140 and the hook groove 150 can be formed integrally. And the hook can be integrated with the automatic " device 100 structure. The position of the paper hook groove 150 is fixed on the scanner 30 and does not move. Therefore, as long as the hook 110 is hooked with the hook groove 15 °, the relative position between the automatic 100 and the scanner 13 ° can be determined and will not be changed ... not shown in the figure) and the optical module (Figure: : The scan image scanned by tracing 15130 can have the best [inventive effect] The date and month μ, + · i are applied to the clamping mechanism of the automatic paper feeder disclosed in the scanner 〇 embodiment, There is a suitable one, which has the advantage of being able to feed the document to be scanned and the optical module paper feeder: variable depth of field.
