Description

Scan actuator

The utility model relates to a kind of scan actuator, is meant a kind of scan actuator with pallet and tooth bar transmission scan device driving force especially.

Science and technology is constantly progressive, and various new products emerge in an endless stream, and are in today of technical progress, also more and more diversified for the requirement of scanner.Except higher and accurate resolution, be built in the main standard that the host computer housing has become computer in the palpus.

Often utilize roller (Roller) to send in the scanner in the prior art,, except easy scratch is scanned, also can on image output, produce abnormal image such as heterochromatic line or black line because can adhere to dust and powder on the roller with scanned.In addition, roller type framework regular meeting holding paper causes very big inconvenience to the user; Have, the roller type framework also can't be applied in the penetration files such as transparency again.And mechanical framework and optical element can not effectively dwindle, and is built in the requirement of computer chassis in not meeting.

Another kind of more advanced and widely used mode is a plat form type scanning apparatus, it is placed in pallet top or within a card casket with scanned, send in the scanner again and scan, must not contact scanned surface like this, the scanning thing can be by scratch, simultaneously, do not resemble the dust that takes the roller type device on the normal cleaning roller yet, improve the convenience of user's operation.

General in-building type scanner is many to be gear train with the rubber covered rollers, but because the inner space of in-building type scanner is limited, so mechanical framework and optical element can't effectively dwindle, has a strong impact on the scan area of in-building type scanner.Again because be responsible for the gear set and the motor of transmission in the mechanical framework, the size that must have certain degree, and optical element is difficult for dwindling especially, has only 4 inches * 6 inches size at most, and therefore a kind of scanner with the area that more exposes thoroughly has the coml necessity.

The purpose of this utility model is to provide a kind of scan actuator, and it utilizes the driving force of pallet and tooth bar transmission scan device, reduces and uses part.

The purpose of this utility model is achieved in that promptly provides a kind of scanister, scans one scannedly, and this scanister comprises at least: one to expose this scanister outside and import scanned feed arrangement; One image that picks up this scanned image data is seized device; One gearing is controlled this feed arrangement and is exposed outsidely and import described scannedly to this scanister, controls this scanning thing the pass through stroke of this device of image scanning and the scanning that realization is seized device to this image.

The advantage of the utility model device is, it uses part few, and volume is transmitted in reduction, increases scan area, and reliable transmission can holding paper, reduces cost.

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

Figure 1A places the overall appearance figure of its gearing internal body for the utility model scan actuator pallet;

Figure 1B is drawn out to the overall appearance figure of this scan actuator engine body exterior for the utility model pallet;

Fig. 2 A is the front elevation of the utility model scan actuator;

Fig. 2 B is the vertical view of the utility model scan actuator;

Fig. 2 C is the side view of the utility model scan actuator;

Fig. 3 is the sectional view of the utility model scan actuator;

Fig. 4 A utilizes tooth bar that the synoptic diagram of driving force is provided for existing scanister;

Fig. 4 B provides the synoptic diagram of driving force for the utility model scan actuator utilizes tooth bar.

Figure 1A places the overall appearance figure of this scan actuator internal body for the utility model scan actuator pallet; Figure 1B pulls out the overall appearance figure of this scan actuator engine body exterior for pallet.By Figure 1B as can be known, almost whole pallet can expose the scan actuator engine body exterior, promotes user's operation ease, this scanning driving device also can in be built in the host computer housing.

Fig. 2 A, Fig. 2 B, with Fig. 2 C respectively to face, to overlook, to describe scan actuator with side view, the primary element of scan actuator shown in the figure comprises: tooth bar (Rack) 201, motor 202, gear set (Gear set) 203, fluorescent tube (Lamp) 204, catoptron (Mirror) 205, camera lens (Lens) 206, transmission shaft (Transmission axis) 207, anti-dazzling screen (Mask) 208, pallet 109 and panel (Plate) 210.When one scanned when being placed on the pallet, the power transmission that gear set 203 can be produced motor 202 is to tooth bar 201 and transmission shaft 207, so that pallet 209 can pass in and out between the scan actuator body; Fluorescent tube 204, catoptron 205, camera lens 206, anti-dazzling screen 208 are used to obtain image data scanned on the pallet 209.

It should be noted, the above-mentioned framework that obtains scanned image data, though with charged coupled device (Charge Coupled Device, capture framework CCD) is done explanation, but still available connect airtight the type sensor (Contact Image Sensor, CIS) or other image-taking device replace it.In addition, scanned pallet or the card casket of also can utilizing of input finished.

The inner structure of scan actuator is illustrated with the sectional view of Fig. 3.Also depict primary elements such as tooth bar 201, motor 202, gear set 203, fluorescent tube 204, catoptron 205, camera lens 206, transmission shaft 207, pallet 209 and panel 210 among Fig. 3.Please note that motor 202 and gear set 203 all are positioned at the scan actuator forefront, can make pallet 209 almost all expose outside the scan actuator body like this.

In addition, the roller seating space of tooth bar 201 cooperates heads gear set 203 to realize the transmission purpose towards the scan actuator internal body, and employed number of elements is lacked than employed roller type framework in the conventional art.Have, because roller type fabric element cost is mostly higher, but scan actuator of the present utility model only needs the element of ejection formation, therefore, reduces cost greatly again.

Fig. 4 A and Fig. 4 B describe existing scanister respectively and the utility model scan actuator utilizes the situation of tooth bar as the driving force source.Mark pallet 400, tooth bar 401, gear 405, pallet width 402 and gear width 403 among Fig. 4 A.Learn that by this figure the roller seating space of tooth bar 401 (Tooth) all is positioned at the pallet outside with gear 405, so the width that existing scanister can scan has only the length shown in the label 402 at the most.But in Fig. 4 B, because the roller seating space and the gear 205 of tooth bar 201 all are included among the pallet 200, so the scanned width that can scan is the length shown in the label 204, it is the summation of label 20 and 203 additions, and scan area is greatly increased.
