Description

Tray Mobile Optical Scanning Device

The utility model relates to a built-in cassette type optical scanning device, in particular to a paper cassette moving optical scanning device which is provided with a cassette transmission device and placed in the disk drive of a personal computer to scan transmissive and reflective manuscripts.

The optical scanner in the prior art has reduced the scanner to a size close to that of an ordinary optical disc drive, and can be combined with a personal computer and built into the position of the magnetic disc drive. In this way, the scanned image data can be directly transferred to the computer for processing. Due to the reduction in size, further simplification of the internal structure of the optical scanner has become the focus of the design.

The products currently on the market are only roller-feed scanners, and their internal structures are very complicated. Referring to the side view of the roller-feed scanner shown in FIG. 1 , the scanner is installed in a box-shaped machine box, and the lamp device 101 and the image reading device 102 are both fixed. When the document enters, the document is placed in the gap between the upper paper guide 103 and the lower paper guide 104, and then the roller 105 is rotated. When the roller 105 rotates and touches the document, the document will be introduced into the body. Scanning occurs simultaneously when the file is imported. There is a transparent reading window 106 below the lower paper guide sheet 104 . The light source of the lamp device 101 can shine on the document through the reading window 106 . The reflected image is transmitted to the image reading device 102 through the mirror 107 . After scanning is finished, the roller 105 sends out the document again.

In addition to the complex structure of this design, the file is driven by rollers, and it is easy to scratch the surface of the file and generate paper dust. Paper dust is easy to adhere to the reading window 106 or the mirror 107, which affects the scanning quality. Moreover, when the paper is inserted into the roller 105, the force is difficult to control, and the paper cannot be fed when the set friction force between the roller and the paper is not reached. In addition, the design of the upper paper guide 103 and the lower paper guide 104 is not ideal. When scanning, the paper or photo may be skewed, so that the scanned image is elongated.

The purpose of this utility model is to provide a carton transmission device, which simplifies the structure of the carton mobile optical scanning device with the function of scanning reflective manuscripts and penetrating manuscripts. It fixes the main optical elements in the body and reduces the length of the optical path. errors and improve image quality.

The purpose of this utility model is achieved by providing a paper box mobile optical scanning device, which is installed in a box-shaped machine box, placed in the position of the disk drive of the personal computer, and it scans the reflected manuscript and the penetrating document.

The utility model also provides a carton transmission device installed in a box-type optical scanning device for scanning reflective and penetrating manuscripts. The box-type optical scanning device at least includes an upper lamp device, a lower lamp device, An image reading device and a box-type machine box, the paper box transmission device includes: a paper box, located in the middle of the box-type machine box, supported by a group of supporting elements and carrying documents in it; a driving gear , connected to a motor, and driven by the motor to rotate; a reduction gear, meshed with the driving gear to rotate; an idler wheel, meshed with the reduction gear to rotate; a passive roller, connected to the an idler, and rotates with the rotation of the idler; and a roller, located at the opposite end of the passive roller in the box-type case, and connected with the passive roller by a traction device; the passive The roller and the roller rotate and simultaneously push the paper cassette.

The advantage of the device of the present invention is that it effectively utilizes the space of the box-type scanner, simplifies the overall structure of the box-type scanner, and because the optical element is fixed, the optical path is stable, the quality is reliable, the assembly and maintenance are easy, and there are few parts ,cut costs.

Below in conjunction with accompanying drawing, describe embodiment of the present utility model, wherein:

FIG. 1 is a schematic diagram of an existing roller-loaded cassette-type optical scanner;

Fig. 2A is the bottom view of the utility model;

Fig. 2B is the front view of the utility model;

Fig. 3A is a partial perspective view of the utility model;

Fig. 3B is a partial perspective view of another embodiment of the present invention.

The utility model includes a carton transmission device which reduces the volume of the box-type scanning device, and simplifies the internal structure of the box-type scanning device. As shown in Figures 2A and 2B, the utility model is installed in a box-shaped machine box 201, and a paper box 202 is provided in the center of the machine box to carry penetrating and reflective manuscripts, such as 4×5 or 4×6 in size negatives, photographs or business cards etc. Both sides of the paper cassette 202 have a support member 203, such as a shaft. In order to allow light to penetrate the document, the paper box 202 includes a transparent upper cover (not shown in the figure) and a transparent flat base 2021 .

The movement of the paper cassette 202 is controlled by a cassette transmission device 204 . The carton transmission device 204 includes a driving gear 2041 , a reduction gear 2042 , an idler wheel 2043 , a set of rollers 2044 and a traction device 2045 . The driving gear 2041 is connected to the motor 2046 and driven by the motor 2046 to rotate. The driving gear 2041 rotates and drives the reduction gear 2042 at the same time. The reduction gear 2042 then drives the idler gear 2043 that engages. The idle wheel 2043 rotates and drives a passive roller 2044 . Passive roller 2044 is connected with a roller 2047 by a traction device 2045, and traction device 2045 can be endless belt or steel rope, and joins one side of paper box 202, as shown in Figure 3A, traction device 2045 is enclosed within passive roller 2044 and On the roller 2047, when the passive roller 2044 and the roller 2047 rotate, the traction device 2045 can be driven to make the paper box 202 move linearly on the shaft 203. The traction device 2045 can also be a lead screw, as shown in Figure 3B, the lead screw 2045 has the function of supporting the paper box 202 and transmission simultaneously, so when using the lead screw 2045, it is not necessary to install the original shaft 203, of course, the passive roller 2044 Also will have corresponding structure with roller 2047.

In order to make the movement of the paper cassette 202 more stable, there is a guide sleeve 205 at the front end of the paper cassette 202 , which is inserted into the shaft 203 so that the paper cassette 202 can move back and forth on the shaft 203 . There is a roller 206 (as shown in FIG. 2B ) at the bottom of the front end of the paper box 202 to support the paper box 202 when moving, so that the paper box 202 can be kept in balance during linear motion. There is an induction device (not shown) below the front end of the paper cassette 202, which can detect the moving position of the paper cassette 202. When the paper cassette 202 moves out to the end point or returns to the starting point, the induction device can send a control signal to stop the motor 2046 from rotating. .

Because the utility model replaces the transmission of scanning by the movement of the paper cassette 202, the light source and image reading device are fixed. The lower lamp device 207 is fixed under the front end of the box-shaped machine box 201 to provide a light source for reflecting manuscripts. The lower light tube device 207 includes a light tube 2071 and a reflector 2072. The reflector 2072 is located below the light tube 2071 so that the light source illuminates from bottom to top.
