Description

Portable Scanner Architecture

At present, general scanners can be divided into two types: the desktop type and the portable type, which are larger in size. The difference between the two is not only the size, but also the overall scanning quality. The main reason is that the portable type scans Most of the scanners are hand-held, and the scanner is moved to scan the image in the area to be scanned. However, the stability of the scanner is not good when the user holds the scanner, and the shaking of the portable scanner leads to poor scanning quality. To solve the above-mentioned problems, the only way to meet the needs of ordinary consumers is to reduce the size of the desktop scanner significantly and completely abandon the operation mode of the hand-held scanner.

In view of the aforementioned problems, the purpose of this utility model is to develop and design a new type of portable scanner to improve the scope and willingness of consumers. The scanner is designed from the traditional bulky desktop type design to It is implemented in a portable way, and its paper feeding and photosensitive scanning devices are improved to design in the form of single-point floating. Through this design, the quality of scanning and the smoothness of paper feeding can be improved.

The portable scanner is mainly composed of an upper cover and a lower cover which are screwed together, and through the setting of the bottom low deck and the high deck in the lower cover, the contact image sensor board and the roller can be It is fixed on it, and the two sides of the contact image sensor board are separately provided with a paper input board and a paper output board. Through the sensor settings on the paper feed board and the paper output board, the smooth entry and exit of the paper can be controlled and the scratches on the paper can be reduced. As for the bottom of the aforementioned contact image sensor board, a spring is provided, so that the motion of the contact image sensor board can be implemented in a unilateral floating manner, and the roller bar can be resisted in a way that the contact image sensor board is permanently in contact with the contact image sensor board. It is beneficial to the transmission and photosensitive scanning of paper.

Advantage and effect of the present utility model are:

1. Since the contact-type image sensing board of the present invention is implemented in a fixed manner, it is only necessary to put the paper into the automatic paper feeder for scanning during the scanning operation, which can greatly reduce the volume of the scanner and can be used in portable use.

2. Since the utility model scanner is implemented in a fixed manner, there is no scanning distortion that often occurs with hand-held portable scanners

3. Since the contact image sensing board and the roller system of the present invention move in a unilateral floating manner, the quality of scanning and the smoothness of paper feeding can be greatly improved.

4. Since the utility model only needs a power supply to operate the contact image sensor board and the roller bar, the overall power consumption demand is very small, and can be directly supplied by the computer without additional power supply device.

Below in conjunction with the embodiment shown in the accompanying drawings, structure, function and feature of the present utility model are described in detail:

Figure 1 and Figure 2 show the perspective view and perspective exploded view of the utility model, which reveal the structure of a portable scanner 1 of the utility model, its overall system is a long rectangular shape, and its front and rear side edges are It is a circular convex plate-shaped paper inlet 11 and a paper outlet 12. This portable scanner 1 is mainly to screw an upper cover 2 and a lower cover 3 together, and pass through the lower cover 3. The setting of the deck 31 and the high deck 32 can respectively fix the contact-type image sensing plate 33 and the rolling bar 34 thereon, and make the rolling bar 34 can be suppressed on the upper edge central side of the contact-type image sensing plate 33, The two sides of the contact image sensing board 33 are separately provided with a paper feed board 35 and a paper discharge board 36, and are set through the sensor 351 on the paper feed board 35. responder 351, and the signal obtained by the sensor 351 drives the driving gear 37 to rotate, and then drives the passive gear 341 and the coaxial roller bar 34 to roll, and when the roller bar 34 rolls, the paper is sucked into the sensor for scanning, and is It is required that the roller bar 34 can keep in close contact with the aforementioned contact image sensing board 33 forever so as to improve its scanning quality and smooth paper feeding. Therefore, a spring 331 is fixed on both sides of the bottom of the contact imaging sensing board 33, The card points 332 provided at the two corners of the bottom edge of the contact image sensing board 33 are stuck on the lower deck 31, so that the contact image sensing board 33 can be displayed in a single-point floating manner, and the contact image The induction plate 33 offsets the rolling bar 34 in a permanent line contact manner.

Figure 3 and Figure 4 show the cross-sectional implementation diagrams (1) and (2) of the present utility model, in which the portable scanner 1 of the present utility model is disclosed, which is mainly composed of an upper cover 2 and a lower cover 3 , wherein the lower cover 3 is provided with a high deck 32, and the high deck 32 is clamped with a rolling bar 34, and the rolling bar 34 can be placed horizontally on the contact image sensing board 33, as for the aforementioned The corners on both sides of the contact image sensing board 33 are provided with a long rectangular flat card point 332, and the card point 332 is engaged with the low card seat 31 and can rotate freely in the low card seat 31. And through the action of the spring 331 arranged on the bottom edge of the touch-type image sensor board 33, the scanning state between the touch-type image sensor board 33 and the roller bar 34 is in a single-point floating line contact, and the touch-type image sensor board 33 has no The displacement is offset, and the traditional surface contact scanning method will cause the distance between the scanning end and the paper 4 to be different due to the unevenness of the paper 4, thereby reducing the overall scanning quality, and due to the contact image sensor The plate 33 can be fine-tuned freely according to the thickness of the paper 4, and the friction paper feeding method is implemented in line contact with the roller bar 34, so that no matter what the thickness of the paper 4 is, it can smoothly pass through the contact image sensor plate 33 and the roller bar 34, and the paper feeding method without traditional surface contact will cause paper jams due to the difference and change of the friction between the paper 4 and the roller 34 and the contact image sensor board 33. (See Figure 5).
