1. Field of the Invention
The present invention generally relates to an apparatus for mounting slides. Specifically, the present invention is a slide securing device using in a flatbed scanner.
2. Background Description
Nowadays flatbed scanners are fully developed computer accessories available on the consumer market. The flatbed scanner can scan colorful documentation and black-white documentation into computer files in order to preserve ordinary images or pictures. The flatbed scanner can also scan particular transparent documents, such as slides or films, by changing the light path from other direction. The transparent scanning operation can be well done in the same manner as ordinary scanning operation.
In the operation for scanning general colorful or black-white documents, the sizes of the documents usually are regular sizes, such as A4, A3, Letter or B5. The flatbed scanner is therefore comprising a document glass for positioning an original document to be scanned. Thus, for the regular sizes, the user simply follows the instructions, such as placing the original document to a predetermined position of the document glass of the scanner, selecting a corresponding size of the original document, and setting parameters of the scanning conditions in a driver program. The scanner will scan the original document by the settings. The scanner is therefore able to scan different documents by acquiring different settings.
Referring to
To solve the above-mentioned problem, a driver software implementing an automatic slide locating feature is available on the market. However, it still takes lots time to locate and scan the slides. Because the sizes of slides are regulated, it is still not efficient if a process of preselecting slides' location is needed.
Thus, there is a locating device provided for scanning original objects which have regulated sizes, for example, slides. The locating device is provided for the scanning process in a flatbed scanner. Referring to
The frame 22 of the locating device is usually made by a soft plastic material. There are several openings as the similar size of slides. However, there is not featured any fixation mechanism in the mentioned locating device. Therefore, the locating device cannot provide precise positions of slides during scanning. Moreover, even though the size of slides is regulated, the thickness of the frame of the slides will vary in different framing brands. The variant thickness of the slide frames will cause diffusion of the scanned image because the scanner cannot precisely focus on slides which have different thickness.
In Taiwan Utility Patent (Republic of China Utility Patent) No. 294,428, there is disclosed a fixation device. Once a frame holds several slides, the frame is placed into a holding member. The holding member is then inserted to a dedicated scanner for transparent scanning process. Thus, the holding member needs an upper and a lower portions for holding the frame. In addition, the dedicated scanner must implement a particular apparatus in order to scan slides via a particular method. This operation is too complicated and inconvenient to the user. In addition, because the slide is only secured by one clip, the slide is able to slip to another position. It causes differences between the actual slide position and predetermined position in the driver program. The actual slide position therefore cannot be acquired. Further, the focus of the scanner cannot be precisely achieved since the slides are not fully secured in a predetermined position and at a fixed height.
SUMMARY OF THE INVENTIONIt is therefore an object of the present invention to provide an apparatus for securing slides on a scanning system in order to acquire precise quality of scanned images.
According to the present invention, the securing cell includes plural clips to mount slides. The scanner is able to directly scan the slides by a predetermined scanning mode in order to save scanning time. Further, the present invention secures slides at a fixed height. The scanner can scan slides by a fixed focus. The scanning quality is therefore improved.
The foregoing and other objects, aspects and advantages will be better understood from the following detailed description of a preferred embodiment of the invention with reference to the drawings, in which:

Further, the aperture 33 includes a first receiving groove 43 and a second receiving groove 48.
The aperture 33 further includes a picking portion, which is located on fourth side 334 of the aperture 33. The user can pick up the slide 5 through the picking portion 44. First, the user pushes the slide 5 to the third side 333 of the aperture 33. The third edge 523 of the slide 5 presses and biases the second securing clip 42. Thus, the fourth edge 524 of the slide 5 can leave the first securing groove 43. The user therefor is able to easily remove the slide 5.
The aperture 33 would yet comprise a first support member 46 and a second support member 47. The first support member 46 extends from the bottom of the first side 331 of the aperture 33. The second support member 47 extends from the bottom of the second side 332 of the aperture 33. The slide 5 is fully supported in the securing cell 31 by the first support member 46 and the second support member 47.
In view of the convenient usage of the frame 32, the frame 32 can be manufactured the same size as the document glass 73 of the scanner 7. As shown in
Although preferred embodiments of the present invention have been described in the forgoing description and illustrated in the accompanying drawings, it will be understood that the invention is not limited to the embodiments disclosed, but is capable of numerous rearrangements, modifications, and substituting of parts and elements without departing from the spirit and scope of the invention. Accordingly, the present invention is intended to encompass such rearrangements, modifications, and substitutions of parts and elements as fall within the scope of the appended claims.
