【Example】

 An embodiment of the present invention will be described below when it is applied to a tracking device for a video camera. In FIG. 1, the tracking device is provided with a platform 11 so as to be horizontally rotatable on a tripod 10. A drive mechanism by a motor, a control unit (not shown), and the like are built in the platform 11. On the upper surface of the platform 11, a camera mount 12 is installed so as to be rotatable in the vertical direction, as shown simply in FIG. A video camera 13 is set on the camera mount 12. Infrared sensors 14 for receiving infrared light are installed on the front surface and both side surfaces of the platform 11. Both sides of the platform 11 are further provided with support members 15R and 15L extending in the horizontal direction away from the platform 11 and a support member 15U extending upward. Ultrasonic wave receivers 16R, 16L and 16U for receiving ultrasonic waves are provided at the tips of the support members 15R, 15L and 15U, respectively. The signals detected by the infrared sensor 14 and the ultrasonic wave receivers 16R, 16L, 16U are supplied to the control section in the platform 11 via a signal processing circuit described later.

Referring to FIG. 3, transmitter 20 is attached to a subject (not shown) such as a human body. This transmitter 20 rotates in the left-right direction and in the up-down direction with respect to the infrared sensor 14 and the ultrasonic wave receivers 16R, 16L, 16U installed on the platform 11 shown in FIG. It is for transmitting a signal to indicate.

Further, the internal circuit configuration will be described with reference to FIG. 4, which schematically shows the internal circuit configuration. The oscillator 20 serves as an oscillating source, and continuously transmits pulsed ultrasonic waves of a constant cycle. It has a section 21 and an infrared irradiation section 22 for irradiating infrared rays as radio waves as needed. The ultrasonic wave transmission unit 21 includes an ultrasonic wave oscillation IC unit 211, a square wave oscillation IC unit 212, a NAND gate 213, an amplifier 214, and an ultrasonic wave emission unit 215.

On the other hand, the infrared irradiating section 22 has an LED (light emitting diode) IC section 221 and a light emitting section 222 including a light emitting diode for infrared rays, and instructs the above-mentioned left / right and up / down rotation. It has operation buttons 223L, 223R, 223U, and 223D for activating the sending of the left-right movement instruction signal, the right rotation instruction signal, the upward rotation instruction signal, and the downward rotation instruction signal. Further, the operation mode of the oscillator 20 is stopped, the ultrasonic wave transmission unit 21 is turned on [hereinafter, this is referred to as an ADF (Automatic Diction Finder) mode], and the infrared irradiation unit 22 is turned on [hereinafter, this is referred to as REM ( Remote mode).] The operation mode changeover switch 224 for setting which mode is selected.

By the way, as is apparent from FIG. 3, the oscillator 20 has a case 201 in which the main circuits of the ultrasonic wave transmitter 21 and the infrared ray irradiator 22 are built. The main surface of the case 201 is divided into a plurality of blocks in the longitudinal direction of the case 201. That is, the main surface of the case 201 includes a first upper block surface A and a second upper block surface B adjacent to the first upper block surface A and slightly lower than the first upper block surface A. And a third upper surface block surface C that is adjacent to the second upper surface block surface B and that is lower than the second upper surface block surface B. The ultrasonic wave emitting section 215 is located near the tip of the first upper block surface A of the case 201, and the infrared ray emitting section 222 is located at the tip of the first upper block surface A of the case. Then, on the second upper block surface B of the case 201, a spring property for hanging the transmitter 20 on a chest pocket or the like of a person's clothing as a subject is placed at a position closer to the center than the installation location of the ultrasonic wave emitting portion 215. There is a hook (mounting member) 225 with a groove. That is, the hook 225 and the operation mode changeover switch 224 are provided on the second upper surface B.

The third upper block surface C is provided with four operation buttons 223L, 223R, 223U, 223D arranged in a direction orthogonal to the longitudinal direction. Furthermore, a battery (not shown) is housed inside the case 201 at the rear portion in the longitudinal direction of the case 201 adjacent to the third upper block surface C.

When the transmitter 20 is used in the REM mode, the transmitter 20 is grasped by a hand, and the light emitting portion 222 is directed toward the platform 11, and any one of the operation buttons 223L, 223R, 223U, and 223D is operated with fingers. Press and hold By this operation, any one of the above-described four types of rotation instruction signals is selectively emitted. Further, when the transmitter 20 is used in the ADF mode, as shown in FIG. 5, the transmitter 20 is hung on the opening edge of the chest pocket 300 of clothes, and pulsed ultrasonic waves having a constant period are continuously supplied. Send to. In other words, when the transmitter 20 is used in the ADF mode, ultrasonic waves are continuously transmitted, so that it is not necessary to hold it by the hand, and it is highly likely that the head 20 always faces the head 11 of the chest pocket of clothes. Just multiply by 300. At this time, it is desirable to place the ultrasonic wave emitting portion 215 in a state of being exposed from the chest pocket 300, and this is possible due to the positional relationship between the ultrasonic wave emitting portion 215 and the hook 225 described above. That is, as shown in FIG. 5, the first block surface A is mounted in a state of being exposed from the chest pocket 300. In this way, the ultrasonic wave emitting portion 215 may be provided in a part of the case 201 that does not obstruct the ultrasonic wave emitting direction in the case 201. In this state, the portion of the case 20 other than the first block surface A is hidden inside the chest pocket 300, so that it can be made visually inconspicuous. It should be noted that the transmitter 20 can be mounted by the hook 225 even when the subject does not move, and can be used in the ADF mode.

[0016]

[Effect of the device]

 As described above, when the transmitter is used in the REM mode, the transmitter has four types of rotations by holding the light emitting part toward the pan head and pressing one of the operation buttons with the fingers. When any one of the instruction signals is selectively emitted and the transmitter is used in the ADF mode, ultrasonic waves can be continuously transmitted while the transmitter is attached to the moving object by the attachment member, so that clothes etc. Can always be left exposed without obstructing the ultrasound emitter. In addition, when the transmitter is attached to the chest pocket of clothes, most of the transmitters are hidden in the chest pocket of clothes, which makes them visually inconspicuous.
