There is something that was done.

By the way, as a surveillance camera, a camera capable of rotating an imaging lens or the like in a predetermined direction such as up, down, left and right has been developed.
Specifically, in order to prevent a failure due to vibration or shock during transportation, the lens can be tilted and rotated in the transportation mode (for example, see Patent Document 1), or by rotating the dial in a predetermined direction. A device configured to be adjustable in tilt (for example, see Patent Document 2) has been developed. In addition, a mechanism for rotating the imaging unit using a fan-shaped spur gear has been developed (see, for example, Patent Document 3).

A pan / tilt head structure for a television camera is also known which is miniaturized by unitizing the whole when the television camera is configured to be pan and tiltable (see, for example, Patent Document 4).

A spring locking portion 1624 for locking a spring member 18 (see FIG. 3) that connects the two is provided.
As a result, since the imaging unit holder 16 and the cover member 1B can be connected via the spring member 18, the imaging unit holder 16 is urged in a predetermined direction, and the imaging unit holder 16 is rotated.

For example, the ROM 153 stores a travel control program 153a, a rotation control program 153b, a monitoring program 153c, and the like.

  The traveling control program 153a controls the driving of the left and right traveling motors 112L and 112R of the traveling unit 11 so as to change the traveling direction based on a control signal transmitted from the remote controller 2 and received via the communication control unit 14, for example. This is a program for causing the CPU 151 to realize the function related to the processing to be performed.

Next, the rotation operation of the imaging unit holder 16 will be described.
In the following description, first, the crank arm 1722 and the imaging unit holder 16 are in the state of FIG. 5, and from the state of FIG. 5 to the state of FIG. Further, the state changes to the state of FIG.

First, based on a predetermined operation of the operation unit 21 of the remote controller 2 by the user, a control signal related to the rotational drive of the rotation motor 171 is transmitted from the communication control unit 22.
In the apparatus main body 1, when the control signal transmitted from the remote controller 2 is received by the communication control unit 14, the CPU 151 reads the rotation control program 153 b from the ROM 153, executes the program 153 b, and receives it. The rotation motor 171 is driven to rotate according to the control signal.
Then, the crank arm 1722 rotates around the axis in the left-right direction Y based on the rotational drive of the rotation motor 171, and the protruding slider 1723 also rotates with the rotation of the crank arm 1722 (FIG. 5 → FIG. 6). At this time, the protruding slider 1723 moves along the inner surface of the engaging groove 1625 while pressing the inner surface downward. As a result, the imaging unit holder 16 rotates around the rotation shaft 1623 so that the front end surface portion 161 faces upward.

When the rotation motor 171 continues to rotate, the crank arm 1722 and the protruding slider 1723 rotate based on the rotation driving (FIG. 6 → FIG. 7). At this time, the projecting slider 1723 moves along the inner surface of the engagement groove portion 1625 while pressing the inner surface downward, and the imaging unit holder 16 further moves the front end surface portion 161 upward. It will turn around the turning shaft 1623 so as to face the direction.
Note that the state shown in FIG. 7 is a state in which the imaging unit holder 16 is rotated so as to have the maximum elevation angle.

Further, when the rotation motor 171 further rotates, the crank arm 1722 and the projecting slider 1723 are rotated based on the rotational drive (not shown), whereby the projecting slider 1723 is engaged. While moving along the inner surface of the groove portion 1625, the inner surface moves while pressing the inner surface upward, and the imaging unit holder 16 rotates about the rotation shaft 1623 so that the front end surface portion 161 faces downward. It will be done.
In this way, the crank arm 1722 and the imaging unit holder 16 change from the state of FIG. 7 to the state of FIG. 6, and further change (return) to the state of FIG. .

As described above, according to the security traveling device 100 of this embodiment, the crank arm 1722 is rotated in accordance with the rotation of the rotation motor 171, whereby the protruding slider 1723 of the crank arm 1722 is engaged with the engagement groove portion 1625. By moving it while sliding along the inner surface, the imaging unit holder 16 can be rotated around the axis in the left-right direction Y. Accordingly, the angle of view of the imaging unit 12 can be appropriately adjusted using the imaging unit holder 16 without providing a dedicated component for rotating the imaging unit 12.
In addition, since the rotation of the imaging unit holder 16 can be performed using the rotation motor 171 that rotates in one direction, the configuration of the control unit 15 such as the CPU 151 that controls the rotation motor 171 is further simplified. be able to.
Therefore, the angle of view adjustment of the imaging unit 12 when monitoring a suspicious person can be realized at a lower cost with a simpler configuration.

Furthermore, the angle of view of the imaging unit 12 can be adjusted appropriately from a remote location by remotely controlling the driving of the rotation motor 171 using the remote controller 2.
In addition, the left and right traveling motors 112L and 112R of the traveling unit 11 can be remotely controlled using the remote controller 2, and the apparatus main body unit 1 can be appropriately moved from a remote location to a predetermined imaging position. Furthermore, for example, in a state where the security mode is not set, the security traveling device 100 can be used as a remotely operated traveling toy, and the security traveling device 100 can be made more attractive.

The present invention is not limited to the above-described embodiment, and various improvements and design changes may be made without departing from the spirit of the present invention.
For example, the remote controller 2 is exemplified as one that controls driving of each part of the apparatus main body 1 such as the traveling unit 11, but is not limited to this, and for example, a rotation motor that rotates at least the imaging unit holder 16. Any device may be used as long as it can control the driving of 171.
Further, communication between the apparatus main body 1 and the remote controller 2 may be performed via a wireless network such as a wireless LAN. That is, for example, a personal computer or the like may be applied as the remote controller 2, and in this case, the operation of the apparatus main body 1 can be controlled based on a predetermined operation of an operation unit such as a keyboard, a mouse, and a joypad.
Examples of the wireless LAN include a network conforming to the Bluetooth standard and the IEEE (Institute of Electrical and Electronic Engineers) 802.11 standard.

  Furthermore, in the said embodiment, although the security traveling apparatus 100 was illustrated as a security apparatus, it can be changed suitably whether it has a traveling function.

  In addition, the shapes and the like of the respective parts such as the imaging unit holder 16 and the gear box 1721 constituting the rotation mechanism unit 17 included in the security traveling device 100 in the above embodiment are merely examples, and the present invention is not limited thereto.
