## Background
BACKGROUND OF THE INVENTION
1. Technical Field
The present invention relates to a bio-sample image pickup device, which allows the operator to pick up the image of a bio-sample and also to view the bio-sample directly.
2. Description of the Prior Art
Please refer to FIG. 1. A conventional bio-sample image pickup device 10 is shown comprising a light source module 11, a filter 13 and an image pickup unit 15. The filter 13 is disposed between the light source module 11 and the image pickup unit 15. When in use, a bio-sample 12 is placed on the light source module 11, and the image pickup unit 15 is operated to pick up the image of the bio-sample 12 through the filter 13. The bio-sample 12 can be, for example, a DNA gel obtained through gel electrophoresis.
In actual practice, the light source module 11 can be a light box adapted to emit light L that can be blue light. The bio-sample 12 can be placed on the top side of the light source module 11 so that the emitted light L can project onto the bio-sample 12. At this time, a part of the emitted light L goes through the bio-sample 12, and the other part of the emitted light L excites the bio-sample 12 to produce a first light L1.
The filter 13 is an amber filter adapted for filtering the light L that passes through the bio-sample 12. The light L can be blue light. The wavelength of the first light L1 is greater than the light L. The filter 12 filter the light L (blue light) and allow the first light L1 to pass therethrough and to project onto the image pickup unit 15 so that the image pickup unit 15 can pick up the image of the first light L1.
The aforesaid bio-sample image pickup device 10 can pick up the image of a bio-sample 12. However, it still has drawbacks. For example, when using the bio-sample image pickup device 10 to pick up the image of a bio-sample 12, the operator may need to perform a follow-up test and analysis on a particular area of the bio-sample 12. At this time, the operator needs to remove the bio-sample 12 from the bio-sample image pickup device 10 and then place the bio-sample 12 on another light source module. Further, the operator must wear a pair of amber eyeglasses so as to see the image of the bio-sample 12 and then to cut off a part of the bio-sample 12 for test and analysis.
SUMMARY OF THE PRESENT INVENTION

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
Referring to FIG. 2A and FIG. 2B, a bio-sample image pickup device 20 in accordance with a first embodiment of the present invention is shown comprising a carrier 21, a light source module 23, a first filter 251, a second filter 253 and an image pickup unit 27. When in use, a bio-sample 22 is placed on the light source module 23, allowing the image of the bio-sample 22 to be picked up by the image pickup unit 27.
The light source module 23 is adapted for emitting light L. The light source module 23 can be a light box. When in use, the bio-sample 22 is placed on the top side of the light source module 23, allowing the emitted light L to be projected onto the bio-sample 22. At this time, a part of the emitted light L excites the bio-sample 22 to produce a different wavelength of first light L1. For example, the bio-sample 22 can be a DNA gel obtained through gel electrophoresis, and the emitted light L excites the bio-sample 22 to produce fluorescence (first light L1).
The carrier 21 is adapted for carrying the light source module 23, allowing the light source module 23 to be moved thereon. The bio-sample image pickup device 20 defines a first position P1 and a second position P2. The light source module 23 is movable between the first position P1 and the second position P2. The first position P1 can be defined as an image pickup zone. The second position P2 can be defined as an operation zone. According to this first embodiment, the carrier 21 is a sliding track. The light source module 23 is slidably mounted on the sliding track (carrier 21), and movable along the sliding track (carrier 21) between the first position P1 and the second position P2.
The first filter 251 and the second filter 253 can be identical, and adapted for filtering the light L emitted by the light source module 23, allowing the first light L1 to pass therethrough. The first filter 251 is positioned in the first position P1. The second filter 253 is positioned in the second position. When the light source module 23 and the bio-sample 22 are in the first position P1, the first filter 251 is disposed above the light source module 23 and the bio-sample 22. When the light source module 23 and the bio-sample 22 are in the second position P2, the second filter 253 is disposed above the light source module 23 and the bio-sample 22.
Further, the emitted light L can be blue light or ultraviolet light. The wavelength of the first light L1 is greater than the emitted light L. The first filter 251 and the second filter 253 are amber filters adapted for filtering blue light or ultraviolet light (the emitted light L).
The image pickup unit 27 is disposed above the first filter 251. When the light source module 23 and the bio-sample 22 are in the first position P1, the first filter 251 is disposed between the light source module 23 and the image pickup unit 27 for filtering the emitted light L that passes through the bio-sample 22, allowing the excited first light L1 to pass through the first filter 251 and to be mapped onto the image pickup unit 27 so that the image formed of the first light L1 can pick up the image of the bio-sample 22, as shown in FIG. 2A.
When the light source module 23 and the bio-sample 22 are in the second position P2, the operator can see the image of the bio-sample 22 through the second filter 253 and cut off a part of the bio-sample 22. The second filter 253 in the second position P2 will filter the emitted light L, allowing the first light L1 to pass therethrough, thus, the operator can see the image of the bio-sample 22 that is formed of the first light L1 and directly cut off a part of the bio-sample 22 in the second position P2, as shown in FIG. 2B.
Further, the first filter 251 can be directly mounted on the image pickup unit 27. For example, the first filter 251 can be mounted on the lens of the image pickup unit 27. In this case, the first filter 251 filters the emitted light L, allowing the image pickup unit 27 to pick up the image of the bio-sample 22 that is formed of the first light L1. Further, the second filter 253 can be set obliquely, or arranged for allowing adjustment of its angular position, facilitating the operator to view the bio-sample 22 through the second filter 253 or to cut off a part of the bio-sample 22, as shown in FIG. 3.
FIG. 4A and FIG. 4B show a bio-sample image pickup device 30 in accordance with a second embodiment of the present invention. According to this second embodiment, the bio-sample image pickup device 30 comprises a carrier 21, a light source module 23, a filter 35 and an image pickup unit 27. When in use, a bio-sample 22 is placed on the light source module 23, allowing the image of the bio-sample 22 to be picked up by the image pickup unit 27.
The filter 35 is mounted on the light source module 21. When the light source module 23 is moved on the carrier 21, the filter 35 is moved with the light source module 23. According to this second embodiment, the filter 35 and the light source module 23 are movable on the carrier 21 between a first position P1 and a second position P2.
When in use, the bio-sample 22 is placed in between the filter 35 and the light source module 23. When the light source module 23 and the bio-sample 22 are in the first position P1, a part of the emitted light L goes through the bio-sample 22, the other part of the emitted light L excites the bio-sample 22 to produce a first light L1. The filter 35 above the light source module 23 filters the emitted light L, allowing the first light L1 to pass therethrough toward the image pickup unit 27 so that the image pickup unit 27 can pick up the image of the bio-sample 22, as shown in FIG. 4A.
When the light source module 23, filter 35 and the bio-sample 22 are in the second position P2, the operator can see the image of the bio-sample 22 through the filter 35 and cut off or a part of the bio-sample 22, as shown in FIG. 4B.
According to this second embodiment, the filter 35 is movable with the light source module 23. Therefore, the image pickup device 30 requires only one single filter 35 to filter the emitted light L in the first position P1 and the second position P2, allowing the image pickup unit 27 to pick up the image of the bio-sample 22 in the first position P1 and the operator to see the image of the bio-sample 22 in the second position P2.
FIG. 5A and FIG. 5B show a bio-sample image pickup device 40 in accordance with a third embodiment of the present invention. According to this third embodiment, the bio-sample image pickup device 40 comprises a carrier 21, a light source module 23, a filter 45 and an image pickup unit 27. When in use, a bio-sample 22 is placed on the light source module 23, allowing the image of the bio-sample 22 to be picked up by the image pickup unit 27.
The filter 45 extends from the first position P1 to the second position P2 so that a part of the filter 45 is disposed between the light source module 23 and the image pickup unit 27. When the light source module 23 is in the first position P1, the filter 45 filters the emitted light L and allows the first light L1 to pass therethrough toward the image pickup unit 27 so that the image pickup unit 27 can pick up the image of the bio-sample 22. When the light source module 23 is in the second position P2, the filter 45 filters the emitted light L and allows the first light L1 to pass therethrough, and therefore the operator can see the image of the bio-sample 22 that is formed of the first the first light L1.
According to this third embodiment, the filter 45 is set above the first position P1 and the second position P2, and adapted for filtering the emitted light L in the first position P1 and/or the second position P2. Therefore, the image pickup device 40 requires only one single filter 45 to filter the emitted light L in the first position P1 and the second position P2, allowing the image pickup unit 27 to pick up the image of the bio-sample 22 in the first position P1 and the operator to see the image of the bio-sample 22 in the second position P2.
Although particular embodiments of the invention have been described in detail for purposes of illustration, various modifications and enhancements may be made without departing from the spirit and scope of the invention. Accordingly, the invention is not to be limited except as by the appended claims.
