Description

Driving Apparatus, and Turn Tripod for Loading and Turning a Digital Camera}

The present invention relates to a rotary drive equipped with a digital camera and a rotating tripod for mounting a digital camera equipped with the rotary drive, and particularly, to automatically take a panorama shot of a subject while rotating the digital camera at a place other than a studio. The present invention relates to a rotary drive device for mounting a digital camera suitable for carrying out the operation and a rotary tripod installed with the rotary drive device.

Conventionally, a technique of combining a plurality of image documents to form a group of image documents, and allowing a plurality of image documents constituting the group of image documents to be sequentially displayed alternately, to give a three-dimensional effect to the image document is known. It is widely used.

This technology is based on the user's request to carefully examine the object in the Internet shopping mall, and to check the object back and forth and right and left, and can be immediately checked with a web browser without a separate plug-in, and instead of a relatively large video, There is an advantage in that the capacity can give a three-dimensional stereoscopic effect.

Thus, such a 3D image effect, such as in the Internet shopping malls to give a "looking effect" to the clothes, sculptures, etc., which require a lot of three-dimensional observation, or to the "use view effect" for multi-functional furniture, special design, etc. that require a lot of usage check Grant a "open effect" to a product, such as a refrigerator that has a high demand for internal observation, or grant a "look around effect" (panoramic effect) to the entire interior of the building or surrounding landscape, etc. It is widely used for the purpose.

Many photographic images to be used for this purpose are obtained by multiple photographing of a subject using a digital camera. In addition, in order to efficiently perform such a plurality of photographing, a separate auxiliary device is used in addition to the digital camera.

Recent developments in using assistive devices to efficiently perform shooting on a subject to which the "looking effect" is to be applied include a turntable on which the subject is placed, a controller for controlling the rotation angle of the turntable, a digital camera and a digital camera. An automatic shooting device configured as a control device for controlling the shooting of the camera is mentioned. According to this automatic photographing apparatus, the photographer places a subject on the turntable, sets the number of photographed images to be obtained in one turn of the turntable, and then orders the photographing to automatically perform a plurality of shots while the turntable rotates to the desired number of subjects. It is easy to obtain a number of images.

On the other hand, a plurality of image capturing (panorama photographing) for imparting a "touring effect" to the inside of a building, etc., is required for an automatic photographing apparatus as described above. However, at the moment, it uses only simple aids and is essentially a level of panorama shooting while turning the camera by hand.

U.S. Patent No. 5,870,642 discloses a support for assisting in rotating the panoramic digital camera by a predetermined angle in such a manual panoramic shooting.

U.S. Patent No. 5,752,113 discloses a panoramic camera mount designed to be rotatable to provide convenience to a panoramic photographer. However, the camera mount is generally operated manually, and although it is described that the mount can be rotated by a server motor, it does not disclose the specific assembly state causing the rotational drive. In addition, since the rotation control function is intended to be applied to a part of the camera mount, it is a unique function of the existing camera mount, so that it can be fixed in two directions (i.e., left, right, up and down) to change the view point of the camera. The ability to bend freely cannot be omitted, which does not solve the problem of the overall complexity of the mount. As a result, in order to be able to fixably rotate in three directions, it is impossible to use a method such as embedded in a housing, thereby making it impossible to make the article light and small. In addition, when the camera mount is automatically rotated by using a motor, it does not solve the problem that the wiring such as a transmission path for transmitting the image photographed by the camera is twisted during shooting.

U.S. Patent Nos. 5,950,018 and 6,192,196 disclose a panoramic photographing camera configured to allow the housing of the camera to rotate about an axis of rotation. However, the technique disclosed in this publication requires the use of a specific camera for panorama shooting, and it is difficult to mount a general-purpose digital camera. For this reason, there is a problem that the degree of freedom in camera selection is poor.

Therefore, as a new type of panoramic shooting aid, various types of digital cameras can be mounted in various ways, and the mounted digital camera can be freely rotated more than 360 degrees without any obstacle of wiring, thereby automating the panorama shooting process. There is a need for the design of a digital camera rotational drive device suitable for the following.

SUMMARY OF THE INVENTION The present invention has been made to realize the above-mentioned conventional requirements, and is a photographing assist mechanism capable of automatically performing panorama shooting while rotating a digital camera, a video camera, and the like. It is a technical object of the present invention to provide a rotary drive device that can be used and a rotary tripod for mounting a digital camera equipped with the rotary drive device.

In particular, the present invention is free to be installed on a tripod for a conventional camera, and is also easy to mount a notebook computer or the like as a control device for a rotary drive unit and a digital camera, and between an external power source, a digital camera, and a control device. It is an object of the present invention to provide a digital camera-mounted rotary drive device for effectively arranging wiring, and a rotary tripod for mounting a digital camera provided with the rotary drive device.

In the control box 3, a drive circuit (control board: see FIG. 3) for controlling the drive motor 21, which is also constituted by a step motor, is disposed, and the drive motor is rotated in accordance with a control signal from a notebook computer or the like. To control. Reference numeral 28 in FIG. 2 denotes an encoder for detecting the rotation speed of the motor.

As described above, the rotary drive device for mounting a digital camera constructed in accordance with the first embodiment has been described, but the present invention is not limited to this configuration.

As a modified embodiment thereof, as in the first modified embodiment shown in FIG. 4, the drive gear 124 of the drive motor 22 is engaged with the fixed gear 143 of the fixed plate 42 to rotate about the rotation axis. It may be configured to. In this case, the control box 3 on which the notebook computer is placed is disposed slightly above and compared to the case of FIG. 2, and is integrated into the housing 21 using the insertion rod 35 in the same manner.

As another modified embodiment, as in the second modified embodiment shown in FIG. 5, the drive motor 122 is laid down so that the rotation axis is in the horizontal axis direction, and the pinion type drive gear 123 is fixed to the rotation axis. The drive gear may be configured to drive on the rack-type fixed gear 243 fixed to the fixed plate 42.

In this modified embodiment, description of some parts has been omitted, but the contents are substantially the same as the foregoing description with reference to FIG.

The first embodiment and the modified example are configured such that the driving motor is rotated integrally with the rotating part, and the control box and the control computer disposed on the control box also rotate integrally with the rotating part, that is, the camera rotates integrally with the camera. There is no fear that the wiring to the control computer is twisted.

On the other hand, in the first embodiment and its modifications, the drive motor is necessarily integrated with the rotating part and configured to rotate together with the control box and the control computer, but it is not necessary to do so. That is, the driving motor generates only the power to rotate the rotating part in the fixed state, it may be designed not to rotate together. In addition, the control box on which the notebook computer is placed does not need to be integral with the rotating part and rotates together, but may be designed to be integrated with the fixing part.

FIG. 6 is a view showing a second embodiment of the present invention, in which the drive motor 52 and the control box 3 are both designed to be integrated with the fixing part 13.

In addition, the control box 3 on which a notebook computer or the like is placed is inserted into the housing 51 and has essentially the same structure and function as shown in FIG. 2 except that the position is fixed without rotation with the camera.

Meanwhile, a communication line for exchanging control signals and video signals between the digital camera 7 and the notebook computer installed in the control box 3 may be disposed outside the housing. It is more preferable to arrange the slip ring 160 inside the method. In this case, however, the slip ring unit 160 should be suitable for this purpose in consideration of the fact that the communication line is not an AC line but a DC line. In this case, it is preferable to add a special noise blocking means to block the noise that may occur in the slip ring unit 160 to the control line.

In the above-described first and second embodiments, the control box 3 is provided as a means for placing a control device such as a notebook computer on the outside of the main body 21 of the rotary drive device. It is not.

For example, as shown in Figs. 7 and 8, the installation of the control box 3 is omitted, and the function of setting the number of panorama shot images to be obtained from the digital camera as the minimum function that the control apparatus should provide. After the function of instructing the start of shooting, and the control unit 72 to perform the drive control function for controlling the drive motor in accordance with the setting and execution command in the form of a hardware, it is rotated together with the rechargeable battery 73 It is also possible to adopt a configuration in which the control panel 71 is installed inside the main body 2 and is installed outside the rotary drive main body 2 to set and execute the operation of the control unit 72.

7 and 8 illustrate a third and fourth modified embodiments, in which a control unit 72, a control panel 71, and a rechargeable battery 73 are installed in the main body 2 of the rotary drive unit of FIGS. 4 and 6, respectively. And an example of a structure in which the control box 3 is omitted.

9 and 10 are views for explaining a third embodiment of the present invention. In this third embodiment, the rotary drive body 200 of the present invention is constructed essentially the same as the drive motor 52 is designed to be integrated with the fixed portion 13 in the configuration of the second embodiment. That is, the fixing part 220 which is the lower end fixed to the tripod leg 205 and the main shaft 204 (the hatched portion from the upper left in FIG. 10 to the lower right) and the rotating part that is the upper end fixed to the camera rotating on the upper end thereof ( 210: hatched portions from the upper right of FIG. 10 to the lower left). As shown in FIG. 10, the driving motor 222 is fixedly installed in the housing 221 of the fixing part 220 to rotationally drive the rotating part 210 integrated with the housing 211.

In addition, the control box 206 and the photographing control computer (laptop type) 208 are not mounted integrally with the rotating part or the fixing part, but are mounted on the support 213, 213 ′ fixed in the middle of the tripod 205. The control box 206 consists essentially of the same components as the example shown in FIG. 3.

Compared with the second embodiment of FIG. 6, the slip driving unit 320, 330, 340, 226, and 212 of the rotary driving device main body 200 according to the third embodiment of FIG. 10 is significantly improved compared to FIG. 6. Form. In terms of the position of the slip ring portion, in the second embodiment of FIG. 6, the slip ring portion 160 is disposed at the center of the rotating shaft, and power transmission for rotating the rotating portion is made outside the rotating shaft. However, in the third embodiment shown in Fig. 10, the power transmission shaft coincides with the center of the rotation shaft, and the slip ring portion is disposed outside the rotation shaft.

In particular, the slip ring portion according to the third embodiment of FIG. 10 is disposed in a configuration in which the disk-shaped rotating plate 212 and the rod-shaped contact holder 226 face each other to increase the reliability of signal transmission. In more detail, a plurality of annular conductors 320 made of a conductive material (for example, brass) are inserted into the rotating plate 212 that rotates about the rotating shaft 213 as part of the rotating part 210. The contact holder 226 fixed to the fixing plate 225 as a part of the fixing unit 220 is fitted with the same number of contacts 330 as the number of the annular conductors 320. The annular conductor 320 and the contactor 330 are in close contact with each other so that the electrical contact state is maintained. In addition, the compression spring 340 is installed at the bottom of the contact as an elastic member so that the electrical contact state can be maintained continuously and effectively. The compression spring 340 pushes the contactor 330 toward the annular conductor 320 to exert elasticity so that the electrical contact between the two can be more effectively maintained.

Wirings 310 and 350 are connected to each of the plurality of annular conductors 320 and the contacts 340, and the wirings are connected to the input / output connection terminals 300 and 400, respectively.

As a result of this configuration, the rotational force of the drive motor 222 is transmitted to the rotation shaft 212 shaft through the drive gear 223 and the driven gear 214, the rotary plate 212 fixed integrally with the rotation shaft is the rotation shaft 213 Although rotated around the plurality of contacts 330 is in contact with the surface of the annular annular conductor 320 of the opposite position. As a result, the electrical connection state between the fixing unit 220 and the rotating unit 210 is maintained, thereby completing the transmission path of control signals and video signals between the rotating camera 207 and the fixed photographing control computer 208. .

Meanwhile, in FIG. 10, the slip ring part is configured to secure a communication line between the annular conductor 320 fitted to the rotating plate 212 and the rod contact holder 226, but the configuration may be changed to another form.

For example, the slip ring portion of FIG. 10 may be configured to be turned upside down. That is, the annular conductor 320 is inserted into a disc-shaped fixing plate (not shown) provided on the fixing part 220 side so as to be in a fixed state, and a rod-shaped rotating bar installed to fix the contactor to the rotating part 210. It can also be configured to install on. In addition, two or more contactors 330 may be disposed symmetrically with each other so as to increase connection reliability between the contact portion 330 and the annular conductor 320 and increase durability.

In FIG. 10, reference numeral 230 denotes a bearing disposed between the fixing part 220 and the rotating part 210. The installation position and the number of installations can be changed to enhance the effect. In addition, "228" is an encoder and is engaged with the driven gear 214 to operate by receiving a rotational force. The position may be installed to move around the drive motor 222, as shown in Figure 2 (reference numeral 28). The wirings 360 and 370, which are the power supply lines and the signal lines, are connected to the connection terminal 400 to control the controller box 206 via the wiring 302 together with the communication line 350 (for example, a USB line). Is connected. 9, the communication line 350 is connected to the photographing control computer 208 via the communication line 303 (for example, a USB port) via the control box 206. The control box 206 is connected to the control computer 208 through a communication line 304 (for example, RS232) to communicate with the control computer 208 and receives the control signal from the control computer to control the driving of the motor. . Meanwhile, the wirings shown in FIGS. 9 and 10 may be modified in other forms. For example, the communication lines 301, 310, and 350 descending from the USB port of the camera pass through the rotating part 210 and the fixing part 220 of the main body 200 of the rotary drive device, and then the power supply line 360 and the signal line. It may be configured to be directly connected to the control computer 208 through a separate connection terminal without passing through the control box 206 in a state separated from the 370.
