Description

Image sensing device

The present invention relates to an image sensing device, and more particularly to an image sensing device for sensing a plurality of objects having different thicknesses.

With the advancement and development of technology, the application of scanners has become more and more extensive. Generally, the scanners are provided with a paper feed/output roller to feed the objects to be scanned into/out of the scanner. During the transport of the object, the image sensor in the scanner senses the object to produce an image of the corresponding object. In general, there are two types of image sensors used in the scanner, one is a Charge-coupled Device (CCD) sensor, and the other is a Contact Image Sensor (CIS). . From the scanning quality point of view, due to the long development time and mature technology of CCD, the scanning quality of CCD is better than CIS, and the CIS scanning machine has the characteristics of low cost, light weight and ultra-thin, which is suitable for a crowded environment. Moreover, there is no need to adjust and heat the machine, so the CIS scanner starts faster than the CCD scanner. With the maturity of CIS technology, CIS scanners have replaced the trend of CCD scanners.

However, since each image sensor has a certain Depth of Field (DOF), when the user wants to use a specific scanner to scan a plurality of objects of different thicknesses, some thickness differences are large. The object cannot be effectively sensed by the image sensor of this particular scanner, resulting in an unclear image. For example, the conventional CIS has a depth of field of about +/- 0.3 mm, while a typical slide has a thickness of between about 1 mm and 3.2 mm, so it can be used to scan a slide with a thickness of 1 mm. CIS scanners cannot be used to scan slides larger than 1.6 mm thick. In addition, other items that can be scanned, such as photo paper, transparencies, general paper, etc., also have different thicknesses. When the user wants to scan a plurality of objects of different thicknesses, it is necessary to use a corresponding scanner for scanning the objects with different thicknesses. This is not only inconvenient for the user, but also increases the cost of the user to purchase different scanners.

Accordingly, it is an object of the present invention to provide an image sensing apparatus that can be used to sense a plurality of objects of different thicknesses to solve the above problems.

According to an embodiment, an image sensing device of the present invention includes a housing, an image sensor, and a transport mechanism. The image sensor and the transport mechanism are both disposed in the housing. A travel path is defined within the depth of field of the image sensor. The transport mechanism is configured to transport a plurality of objects of different thicknesses, and the center line of each of the objects is substantially maintained on the travel path, so that the image sensor senses the objects to generate an image corresponding to the objects.

According to another embodiment, an image sensing device of the present invention includes a housing, an image sensor, and a transport mechanism. The image sensor and the transport mechanism are both disposed in the housing. The transport mechanism includes a first transmission combination. The first transmission assembly includes a first transmission member and a second transmission member. The first transmission member and the second transmission member are relatively movable and drive the objects into the housing in a traveling direction, so that the image sensor senses the objects to generate an image corresponding to the objects.
