BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a document camera for photographing an object on a platen with image pickup means.

[0002]

2. Description of the Related Art A conventional example of a document camera is shown in FIGS.
Will be explained.

FIG. 10 is a perspective view showing a state in which a document image is photographed by the conventional document camera, and FIG. 11 is a side view showing a state in which the document camera shown in FIG. In the figure, 101 is a document table unit, 102 is a document table formed on the document table unit 101, 102a is a document placed on the document table 102, and 103 is a document table unit 101 for operating the document camera. An operation panel provided at an end portion, which is configured by an electric switch or the like.

Reference numeral 105 denotes a lower camera arm, and 105a denotes a rotary shaft installed on the lower camera arm 105. The lower camera arm 105 is rotatable around the rotary shaft 105a in the direction of the arrow L in the drawing so as to be rotatable around the platen unit 101. Held in. Reference numeral 106 denotes an upper camera arm, and the lower camera arm 105 and the upper camera arm 106 are configured to be extendable and contractible in the axial direction.

Reference numeral 107 denotes an image pickup unit, and 108 denotes a document table 1.
02 is a photographing lens for photographing the original 102a. Here, the imaging unit 107 is held by the upper camera arm 106 so as to be rotatable about the axis of the upper camera arm 106 (rotatable in the direction of arrow J in the drawing).

Reference numeral 109 is a right illumination unit, 109a is a fluorescent lamp of the right illumination unit 109, 110 is a right illumination arm, and the right illumination arm 110 is held by the document table unit 101 so as to be rotatable in the direction of arrow N in the figure. There is. The right lighting unit 109 is held by the right lighting arm 110 so as to be rotatable in the direction of arrow Q in the figure. 111 is a left lighting unit,
111a is a fluorescent lamp of the left illumination unit 111, 112 is a left illumination arm, and the left illumination arm 112 is held by the document table unit 101 so as to be rotatable in the arrow M direction in the drawing.

The left illumination unit 111 is held by the left illumination arm 112 so as to be rotatable in the direction of arrow R in the figure.
Reference numeral 113 denotes a lock release lever that releases a lock state of a lock device (not shown) that locks the lower camera arm 105 with respect to the document table unit 101. The lock release lever 113 is moved in the direction of arrow O to bring the lock state. It can be canceled.

Next, the structure when the document camera is in the original photographing state will be described.

In the document camera, as shown in FIG. 10, a photographing lens 108 is arranged above the document table 102 so that the light beam from the document table 102 is incident. The position of the image pickup unit 107 holding the taking lens 108 is determined by this. In the image pickup unit 107, a photoelectric conversion element of CCD (not shown) is arranged at the image forming position of the taking lens 108, and an electric signal output from this photoelectric conversion element is converted into a video signal by a control circuit (not shown).
Then, the video signal is output to a device (not shown) such as a projector electrically connected to the document camera. Moreover, FIG.
In the state shown in 0, the illumination state of the original 102a can be adjusted by rotating the right illumination unit 109 and the left illumination unit 111 in the directions of arrows Q and R in the drawing, respectively.

Next, the setting operation from the document photographing state of the document camera to the housed state will be described.

When the document camera is in the state shown in FIG. 10 (original image pickup position), the image pickup unit 107 is moved to the arrow J.
Rotate in the direction. Then, by pushing the upper camera arm 106 into the lower camera arm 105 (in the direction of arrow K in the figure), the length of the entire camera arm is shortened and the position of the image pickup unit 107 is brought closer to the document table 102. Then, the lock release lever 113 is moved in the direction of the arrow O in the figure to move the lower camera arm 10 to the document table unit 101.
The fixed state of 5 is released, and the lower camera arm 105 is rotated in the direction of the arrow L in the drawing about the rotation shaft 105a to move the image pickup unit 107 on the document table 102. Here, the positional relationship between the image pickup unit 107 and the document base unit 101 is automatically fixed again at a position near the position where the image pickup unit 107 contacts the document base unit 101. Further, in this fixed state, the lock release lever 113 is moved in the direction of arrow O in the figure to release the fixed state, and the lower camera arm 105 with respect to the original table unit 101.
That is, the image pickup unit 107 can be moved.

Next, the left illumination arm 112 is rotated in the direction of arrow M in the figure, and the left illumination unit 111 is rotated in the direction of arrow R in the figure so as to obtain the configuration of FIG. This state is shown in FIG. Then, from this state, the right illumination arm 110 and the right illumination unit 109 are also rotated in the direction of the arrow N in the figure, and the right illumination unit 109 is moved to the arrow Q in the figure so that the storage state of the document camera becomes smaller.
Rotate in the direction. In this way, the left and right illumination units 109 and 110 are folded to bring the document camera into a stored state (not shown). Further, the setting operation from the housed state of the document camera to the document photographing state is performed in the reverse order of the setting operation from the document photographing state to the housed state.

[0013]

However, in the document camera of the conventional example, in the housed state, the taking lens 108, which is a delicate component having relatively weak strength, the fluorescent lamps 109a of the left and right illumination units 109 and 111, 1
11a and the operation panel 103 are exposed to the outside. Therefore, there is a serious problem that the fluorescent lamps 109a and 111a are destroyed due to an inadvertent impact when the document camera is stored, or the lens surface is soiled by touching the taking lens 108. . In order to solve this problem, the taking lens 108 such as a protective cover and a lens cap, the fluorescent lamps 109a and 111a of the left and right illumination units 109 and 111, and the dedicated protection member for the operation panel 103 are required, and the document camera The structure becomes complicated.

Further, since the upper camera arm 106 is pushed into the lower camera arm 105 (in the direction of arrow K in the figure), the image pickup unit 107 and the original table unit 10 are arranged.
1 may be connected and the electric signal line (not shown) passing through the camera arms 105 and 106 may be largely loosened, but the electric signal line may be disconnected due to repeated expansion and contraction operations of the upper camera arm 106 and the lower camera arm 105. There is.

In order to avoid this, if the upper camera arm 106 and the lower camera arm 105 are integrated, the image pickup unit 107 projects toward the front from the front portion (operation panel 103) of the document table unit 101 when the document camera is stored. Therefore, not only the size of the document camera when stored is increased, but also the image pickup unit 107, which has a relatively low mechanical strength, is likely to be impacted from the outside during storage, so that the document camera is easily damaged. Further, at this time, in order to prevent the image pickup unit 107 from projecting forward from the front portion (operation panel 103) of the document table unit 101,
It is necessary to further increase the size of the document table unit 101.

Further, when the document camera is stored, the document table 1
Since 02 is exposed to the outside, it is easily stained.

In order to solve these problems, the original document holding means, the image pickup means for photographing the original document held by the original document holding means, and the original table and the only one provided on the optical path of the image pickup means. This is possible by providing a reflecting means and a movable holding means for holding the image pickup means and the reflecting means.

However, with such a construction, there is a problem that the reflecting means is in front of the user's eyes, and a large force is erroneously applied to the reflecting means to destroy the reflecting means. or,
Since the reflecting means is between the image pickup means and the document table, there is a problem that it is difficult to install measuring equipment at the time of assembly and adjustment (for example, when taking a zoom balance of the lens, adjust with a collimator).

The present invention has been made in view of the above problems, and its object is that it has better operability than conventional ones, has a simple structure, and is protected from damage due to inadvertent force from the outside. It is to provide a document camera that can be easily assembled and adjusted.

[0020]

In order to achieve the above object, the present invention provides a document holding means, an image pickup means for photographing a document held by the document holding means, the document holding means and the image pickup means. The only reflection means provided on the optical path,
The movable holding means holds the imaging means and the reflecting means, and the reflecting means is rotatably supported by the movable holding means and can be held at a photographing position. It is characterized in that it is configured to rotate when added.

The document camera has a lock device (not shown) for fixing the relay unit 5 to the document table unit 1 and a lock release device (not shown) for releasing the fixed state in the original photographing state and the stored state.

Similarly, a lock device (not shown) for fixing the image pickup unit 7 to the relay unit 5 in the document photographing state and the housed state of the document camera, and a lock releasing device (not shown) for releasing the fixed state. Have. Further, the rotary shaft 6, the rotary shaft 10 and the rotary shaft 12 are configured in parallel. The electric signal line 20 passes through the center of the rotary shaft 6 and the rotary shaft 10 or in the vicinity thereof to connect the control circuit 15, the document illumination unit 9 and the image pickup control circuit 17. Further, the electric signal line 21 passes through the center of the rotary shaft 6 and the rotary shaft 12 or in the vicinity thereof to connect the control circuit 15 and the display panel 13.

Next, the configuration when the document camera is in the original photographing state will be described.

As shown in FIGS. 1 and 4, the document camera reflects the light beam 8d from the document table 2 by the reflecting mirror 14 and enters the taking lens 8 as the light beam 8c into the taking lens 8 and the taking lens 8. Are arranged. The positions of the mirror unit 11 and the image pickup unit 7 are determined along this light flux. When the mirror unit 11 is set at the shooting position, the positioning pin 22 is fitted in the shooting position recess 5e and is held at the shooting position.

Next, at the time of assembly and adjustment, the mirror unit 11
In order to retreat to the outside of the photographing optical path, a predetermined force (for example, 5 kg) or more is applied and rotated in the direction of the arrow Y in FIG. The spherical portion 22a of the positioning pin 22 rides on the sliding portion 5f, the positioning pin 22 moves against the force of the biasing member 23, and escapes from the photographing position recess 5e. After that, the positioning pin 22 slides on the sliding portion 5f, falls into the recess 5g outside the optical path, and is fitted again. As a result, the mirror unit 11 is set outside the image-taking optical path, the measuring equipment can be set directly on the image-taking lens 8, and the zoom balance adjustment and the like can be easily performed. This state is shown in FIG.

In the image pickup unit 7, a photoelectric conversion element such as CCD (not shown) is arranged at the image forming position of the taking lens 8.
The electric signal output from the photoelectric conversion element is converted into a video signal by the image pickup control circuit 17, and the video signal is mirror-inverted and transmitted to the control circuit 15 in the document table unit 1 via the electric signal line 20. Here, the luminous flux 8 from the document table 2
Since d is reflected only once by the reflecting mirror 14 and guided to the photographing lens 8, the video signal obtained from the photographed image is mirror-inverted. The mirror inversion process of the video signal may be performed by another part such as the control circuit 15.

The video signal is output from the control circuit 15 via the electric signal line 19 and the contact portion 16 to a device (not shown) such as a projector electrically connected to the document camera. Further, the video signal is transmitted to the display panel 13 through the electric signal line 21, and the captured video is displayed. Here, the display panel 13 is installed on the surface of the mirror unit 11 (the surface opposite to the reflecting mirror 14). Therefore, a person who operates the document camera can exchange the document 2a and operate the operation panel 3 from the operation panel 3 side, and can see the contents displayed on the display panel 13 from the same place.

Further, the display panel 13 is replaced by the mirror unit 11
By installing it above, it is not necessary to provide a dedicated holding member for the display panel 13 separately from the mirror unit 11, so that not only a document camera having a simple structure can be provided, but also a display when the document camera is housed is described in detail later. The protection member for the panel 13 may not be provided. In addition, the display panel 1 displays the state of the output image quality such as the contrast and hue of the image output to the outside.
3 may be displayed, and the content displayed on the display panel 13 is not limited to the captured image captured by the capturing lens 8.

Further, as shown in FIGS. 3 and 4, the document illumination unit 9 is provided at the end of the image pickup unit 7, and outside the light beam 8e (optical axis 8b) in the document photographing state of the document camera.
Directly illuminating the document table 2 obliquely from the side opposite to (without the reflection mirror 14). Therefore, even if the original 2a is a glossy original (reflection original) like a photograph, the original 2a taken by the taking lens 8 is attached to the original illumination unit 9.
The light source of is not reflected. Here, if the document illumination unit 9 is inside the light beam 8e (on the optical axis 8b side), the document 2a
In the case of a reflection original, the illumination is reflected by the original 2a and directly enters the photographing lens 8 as reflected light, so that a high-quality photographed image cannot be obtained.

Further, the document illumination unit 9 is the image pickup unit 7.
Since it is integrated with the image pickup unit 7, it is not necessary to provide a dedicated holding member for the document illumination unit 9 separately, and a document camera having a simpler configuration can be obtained. Furthermore,
The electric signal line from the control circuit 15 to the document illumination unit 9 and the electric signal line from the control circuit 15 to the image pickup control circuit 17 can be made common.

Further, since the document illumination unit 9 is on the side opposite to the operation panel 3, there is a large space on the operation panel 3 side, and the document illumination unit 9 is operated when the document 2a is replaced or the operation panel 3 is operated. There is no physical obstacle. That is, a person who operates the document camera can replace the document 2 a and operate the operation panel 3 without being disturbed by the document illumination unit 9.

Further, since the original document illumination unit 9 directly illuminates the original document table 2 from above without passing through the reflecting mirror 14, the original document illumination unit 9 cannot be directly seen by the person who operates the document camera. . Therefore, the person who operates the document camera can operate the document camera without feeling glare.

Next, the setting operation from the document photographing state of the document camera to the housed state will be described.

When the document camera is in the state shown in FIGS. 1 and 4 (original image pickup position), the lock state of the image pickup unit 7 is released by the lock release device (not shown), and the image pickup unit 7 is unlocked in the direction of arrow A in FIG. Rotate the imaging unit 7,
When the image pickup unit 7 is parallel to the relay unit 5 (the storage position of the image pickup unit 7), the image pickup unit 7 is locked again by a lock device (not shown) of the image pickup unit 7. In this state, since the taking lens 8 is covered by the relay unit 5 in the concave portion 5b, the taking lens 8 can be protected without attaching a lens protection member such as a lens cap to the taking lens 8 when the document camera is stored.

Next, the case of housing the mirror unit 11 will be described.

A predetermined force (for example, 5 kg) or more is applied to rotate in the direction of arrow X in FIG. Positioning pin 2
The second spherical surface portion 22a rides on the sliding portion 5d, the positioning pin 22 moves against the force of the biasing member 23, and escapes from the photographing position concave portion 5e. After that, the positioning pin 22 slides on the sliding portion 5d, falls into the storage position recess 5c, and is fitted again. As a result, the mirror unit 11 is set to the storage position. This state is shown in FIG.

As can be seen from FIG. 5, at this time, the storage position of the mirror unit 11 is the same as a part of the document photographing position of the image pickup unit 7. Therefore, the storage form of the imaging unit 7 and the mirror unit 11 is smaller.
Further, at this time, since the reflecting mirror 14 is covered by the relay unit 5, the reflecting mirror 14 can be protected without attaching a protective member such as a protective cover to the mirror unit 11 or the reflecting mirror 14 when the document camera is stored.

In consideration of the photographing position, the storage position, and the frequency of use outside the photographing optical path, since the movement to the outside of the photographing optical path for assembly adjustment is small, the sliding portion 5f is higher than the sliding portion 5d. However, it is possible to make it difficult for the spherical surface portion 22a to climb up. Then, the lock release device (not shown) of the relay unit 5 unlocks the relay unit 5, and the relay unit 5 is rotated in the direction of arrow C in the figure, so that the relay unit 5 is parallel to the document table unit 1 (the relay unit 5). 5), the relay unit 5 is locked again by a lock device (not shown) of the relay unit 5. This state is shown in FIG.

As can be seen from FIG. 6, since the document illumination unit 9 and the display panel 13 are covered by the document table 2, the document illumination unit 9 and the mirror unit 11 or the display panel 13 are provided with a protective cover or the like when the document camera is stored. The display panel 13 can be protected without attaching a protection member.
Further, since the document table 2 is also covered with the relay unit 5 when the document camera is stored, the document table 2 has a structure that does not easily get dirty during storage. Further, the setting operation from the housed state of the document camera to the document photographing state is performed in the reverse order of the setting operation from the document photographing state to the housed state.

As described above, the functions of the photographing lens 8, the document illumination unit 9, the mirror unit 11, and the display panel 13, which are components having generally low mechanical strength when the document camera is stored, are relayed. Unit 5
Need not be provided with a dedicated protection member for the taking lens 8, the document illumination unit 9, the mirror unit 11, and the display panel 13, and has a simple structure when housed, resulting in an integrated and durable form, and a mechanical structure. It is possible to provide a document camera having high strength and high reliability, and when the mirror unit is in the photographing position, the arrow camera may mistakenly move in the direction of arrow X or Y in FIG.
When a directional force is applied, the spherical portion 22a rides on the photographing position concave portion 5e and the mirror unit 11 is destroyed, which can be avoided.

Further, the original table unit 1, the relay unit 5, the relay unit 5, the image pickup unit 7, and the relay unit 5
The mirror unit 11 and the mirror unit 11 are not engaged by a mechanism for expanding and contracting as in the conventional example, but are rotatably engaged by the rotary shaft 6, the rotary shaft 10, and the rotary shaft 12, respectively, and
The electric signal line 20 and the electric signal line 21 at or near the center of the rotary shaft 10, the electric signal line 20 at or near the center of the rotary shaft 10, and the electric signal line 21 at or near the center of the rotary shaft 12. Therefore, it is not necessary to greatly loosen the electric signal lines 20 and 21 in the vicinity of the mutual engaging portions of the respective units as in the case of engaging with a mechanism for expanding and contracting,
Further, since the electric signal lines 20 and 21 do not move largely during the setting operation from the document photographing state of the document camera to the housed state and during the setting operation from the housed state to the document photographing state, the electric signal lines 20 and 21 are disconnected. Also, the serious risk of connection failure can be greatly reduced, and the document camera can be made highly reliable.

Further, since the respective rotation axes are parallel, the relay unit 5, the image pickup unit 7, and the mirror unit 11 can be moved within the same rotation plane to switch the document photographing state and the storage state of the document camera. Therefore, the rotation direction of each unit is uniform, and the document camera can be easily operated.

A handle 4 provided adjacent to the operation panel 3 when the document camera shown in FIG. 6 is stored.
2 is shown in the state of being pulled out in the direction of arrow D.
As described above, when the handle 4 is provided at a position adjacent to the operation panel 3 in the document camera of the present embodiment, the handle 4 can be held in the state of FIG. 2 and the document camera can be easily carried.

As is apparent from the above description, according to the present invention, the document holding means, the image pickup means for photographing the document held by the document holding means, the document holding means and the image pickup means. And a movable holding means for holding the image pickup means and the reflecting means, the only reflecting means provided on the optical path.
Since the reflecting means is rotatably supported by the movable holding means, can be held at the photographing position, and is rotated by applying a predetermined force or more at the photographing position, the operability is better than in the past. It is possible to obtain a document camera which has a simple structure, is protected from damage due to inadvertent force from the outside, and is easy to assemble and adjust.
