<Outline of lens unit>
An outline of a lens unit according to an embodiment of the present invention will be described with reference to FIGS.

  FIG. 1 is a perspective view showing an example of a lens unit 1 according to an embodiment of the present invention. FIG. 2 is a perspective view of the lens unit 1 shown in FIG. 1 as viewed from the back side. FIG. 3 is a front view of the lens unit 1 for explaining an arrangement state of a plurality of lenses. 4 is a cross-sectional view taken along line AA in FIG. FIG. 5 is a diagram illustrating a state in which the lens unit 1 is attached to the electronic device 100. FIG. 6 is a schematic diagram for explaining the relationship between the lens of the lens unit 1 and the imaging unit 110 of the electronic device 100. In FIG. 6, for convenience of explanation, components other than the lens 42 of the lens unit 1 are omitted.

  As illustrated in FIGS. 1 to 3, the lens unit 1 includes a receiving case 2, a front case 3, a lens component 4, and a slide knob 5. The lens component 4 is provided so as to be movable inside the receiving case 2 and the front case 3, and is a component in which a plurality of lenses (lenses 42, 43, and 44 shown in FIG. 3) are integrated. Further, the lens component 4 is held by the slide knob 5 as shown in FIG. 4, and moves in the longitudinal direction in conjunction with the slide operation of the slide knob 5 in the longitudinal direction (X direction in FIG. 1) by the user. . As shown in FIGS. 5 and 6, the lens unit 1 is configured to be attachable so as to face the imaging unit 110 of the electronic device 100.

  The electronic device 100 is a notebook computer as shown in FIG. 5, for example. Note that the electronic device 100 is not limited to a notebook personal computer, and may be, for example, a tablet terminal including a single housing. The electronic device 100 includes an input side housing 102 and a display side housing 104.

  The input housing 102 has a keyboard on which operation keys (not shown) are arranged. The display side housing 104 is connected to the input side housing 102 so as to be openable and closable. Further, the display-side housing 104 is configured to be used separately from the input-side housing 102. As shown in FIG. 6, the display-side housing 104 includes an imaging unit 110 and a display screen 120.

  The imaging unit 110 is built in the display-side casing 104 and includes a lens 112 and an imaging element 114. The lens 112 collects incident light on the image sensor 114. The image sensor 114 is, for example, a CCD or a CMOS. The image sensor 114 converts the amount of incident light collected by the lens 112 for each of R, G, and B, and outputs an analog signal.

  The display screen 120 is provided on the opposite side of the display side housing 104 from the surface on which the lens unit 1 is attached. The display screen 120 displays an image obtained by imaging the subject by the imaging unit 110 or displays the subject in live view. In addition, a touch panel that can be touch-operated by the user is superimposed on the display screen 120. When the user separates the display-side casing 104 from the input-side casing 102 and uses it, the user performs a touch operation and images the subject with the imaging unit 110.

  A recess 105a (FIG. 5) is formed on the upper surface 105 of the display-side housing 104 along the longitudinal direction of the housing. The recess 105a communicates with an exhaust hole through which air in the display-side housing 104 is discharged, for example. The lens unit 1 is attached to the electronic device 100 by hooking the hook into the recess 105a. The lens unit 1 has a double-sided tape affixed to the back side, and is fixed to the display-side housing 104 with the double-sided tape.

  Incidentally, the imaging unit 110 of the electronic device 100 can capture a plurality of media having different sizes. For example, the imaging unit 110 images A4 size paper, A5 size paper, a license, or the like as a medium. As described above, when images of various sizes of media are captured, the lens 112 in the imaging unit 110 alone is not focused even if the distance between the electronic device 100 and the media is adjusted for imaging. Cases may occur. That is, an out-of-focus image is captured. In particular, when the user wants to perform OCR processing based on an image captured by the user, the OCR processing cannot be performed if the image is out of focus and is out of focus.

  Therefore, in the present embodiment, the lens unit 1 having a plurality of lenses 42, 43, and 44 can be attached to the electronic device 100. The lenses 42, 43, and 44 have lens characteristics suitable for imaging a specific medium when used in combination with the lens 112 of the imaging unit 110. For example, the lens 42 has a characteristic of focusing when imaging A4 size paper, the lens 43 has a characteristic of focusing when imaging A5 size paper, and the lens 44 has a license. Has a characteristic of being in focus when an image is captured.

  In the present embodiment, according to the type of medium that the imaging unit 110 captures, the user can select one of the lenses 42, 43, and 44 arranged along the longitudinal direction of the lens unit 1 as illustrated in FIG. Switching is possible so that one lens faces the lens 112 (see FIG. 6). For example, the user switches to the lens 42 when imaging A4 size paper, switches to the lens 43 when imaging A5 size paper, and switches to the lens 44 when imaging a license. Switching between the lenses 42, 43, and 44 is performed by sliding the slide knob 5 of the lens unit 1.

  FIG. 7 is a plan view of the lens unit 1 for explaining a plurality of positions of the slide knob 5. FIG. 7A shows the first position of the slide knob 5 in which the lens 42 of the lenses 42, 43, 44 faces the lens 112. FIG. 7B shows the second position of the slide knob 5 where the lens 43 faces the lens 112. FIG. 7C shows a third position of the slide knob 5 where the lens 44 faces the lens 112. The user places the slide knob 5 at the first position in FIG. 7A when imaging A4 size paper, and moves the slide knob 5 in FIG. 7B when imaging A5 size paper. When the license is photographed at the second position, the slide knob 5 is located at the third position in FIG.

Here, the flow of imaging of the medium S by the electronic device 100 to which the lens unit 1 is attached will be described with reference to FIGS.
FIG. 8 is a schematic diagram illustrating a state in which the medium S is imaged by the electronic device 100 in which the lens unit 1 is attached to the display-side housing 104. FIG. 9 is a diagram showing an image G of the medium S displayed in live view on the display screen 120. In FIG. 8, the display-side housing 104 to which the lens unit 1 is attached is used separately from the input-side housing 102.

  Here, it is assumed that the medium S to be imaged is A4 size paper. Since the medium S is A4 size paper, the user places the slide knob 5 at the first position in FIG. The focal lengths of the lenses 42, 43, and 44 of the lens unit 1 are set so that the focus is best when the image G is displayed on the entire display screen 120 as shown in FIG. For this reason, the user brings the electronic device 100 closer to the medium S to a position where the image G for live view display of the medium S is displayed on the entire display screen 120. Thereby, since the user can grasp | ascertain an appropriate imaging position easily, it becomes possible to acquire the clear image G easily.

Further, when the user continues to image A5 size paper or a license, the user can slide the slide knob 5 without replacing the lens unit 1 to obtain a clear image G corresponding to the medium to be imaged. It can be acquired. As described above, it is possible to appropriately image a plurality of types of media with a simple operation.
