Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a motion control device,
In particular, the present invention relates to a control device that can control the operation of a device such as a camera-integrated VTR from outside the device or in the device body.

[0002]

2. Description of the Related Art Conventionally, a remote control function has greatly contributed to improving the operability of a device such as a VTR with a built-in camera, but normally, a remote control transmitter is used from outside the device. It emits infrared rays and transmits an infrared code signal (pulse code signal), and the infrared code signal is extracted by the light receiving section of the device body only in the infrared region, and then the infrared code signal is automatically adjusted to an appropriate output level. Amplitude is controlled by the gain control circuit section,
Next, the so-called pulse code signal whose amplitude was limited by the limiter circuit section was read by the microcomputer equipped in the equipment, and the function operation was started.

In addition to the configuration having the remote control function described above, a conventional control device for generating an infrared code signal from the inside of the device to control the operation of the device will be described below with reference to FIG.

The conventional control device comprises a remote control transmitter 2 for transmitting an infrared code signal which is a control signal from the outside of the camera-integrated VTR 1 which is a device, and the remote control transmitter 2 is provided in the camera-integrated VTR 1. The infrared transmitting filter 3 which receives the infrared code signal transmitted from the infrared transmitting filter 3 and transmits only the infrared region, and the infrared transmitter 4 which is mounted on the inner surface of the camera integrated VTR 1 and transmits the infrared code signal from the inside of the camera integrated VTR 1. An infrared transmission filter 5 which receives an infrared code signal transmitted from the infrared transmitter 4 and transmits only an infrared region, and an infrared code which is embedded in the cabinet inner wall of the camera-integrated VTR 1 and transmits the infrared filter 5. Light guiding pipe 6 for guiding a signal, and the above infrared transmission filter A light receiving section 7 for receiving the infrared code signal transmitted through the light source and the infrared code signal induced by the light guiding pipe 6, and an automatic gain control circuit for controlling the infrared code signal received by the light receiving section 7 to an appropriate amplitude. Part 8 and
A limiter circuit unit 9 that limits the amplitude of the infrared code signal whose amplitude is controlled by the automatic gain control circuit unit 8 into a pulse code signal, and amplifies the pulse code signal whose amplitude is limited by the limiter circuit unit 9. And a buffer 10 for outputting to a microcomputer (not shown) for shifting to a functional operation corresponding to the pulse code signal.

In the control device configured as described above, after the infrared code signal transmitted from the remote control transmitter 2 outside the camera-integrated VTR 1 passes through the light receiving path A,
The light passes through the infrared transmitting filter 3 and reaches the light receiving portion 7.
On the other hand, the infrared code signal transmitted from the infrared transmitter 4 passes through the light receiving path B, passes through the infrared transmitting filter 5, and is guided by the light guiding pipe 6 to reach the light receiving unit 7. Then, the automatic gain control circuit section 8 controls the amplitude of the infrared code signal received by the light receiving section 7 so that the gain is large when the infrared code signal is small, and the gain is small when the infrared code signal is large, and the limiter circuit section 9 is used. The infrared code signal whose amplitude is controlled by the automatic gain control circuit section 8 is amplitude-limited to a pulse code signal, and the buffer 10 amplifies the pulse code signal whose amplitude is limited by the limiter circuit section 9 and a microcomputer (not shown). No.), and the microcomputer (not shown) shifts to a functional operation corresponding to the pulse code signal.

Further, in the control device according to FIG. 8 described above, the remote control transmitter 2 having the function of the infrared transmitter 4 is, as shown in FIG. 9, a camera-integrated VTR1 and a camera-integrated VTR1. A first infrared ray receiving window 1a for receiving an infrared code signal transmitted from an external remote control transmitter 2 and a mounting portion 1b to which the remote control transmitter 2 is attachable / detachable are attached to the attaching portion 1b. Some have a second infrared light receiving window 1c for receiving the infrared code signal transmitted from the remote control transmitter 2 in the state.

The control device according to FIG. 9 uses one remote control transmitter 2 for remote operation from the outside of the camera-integrated VTR 1 and also mounts it on the mounting portion 1b to provide a device on the camera-integrated VTR 1 main body side. It can also be operated.

[0008]

However, with the above-described control device, in the case of a portable device such as a camera-integrated VTR, it becomes difficult to receive an infrared code signal from the inside of the device when used outdoors. There is a problem that it will end up. In other words, under strong sunlight outdoors, when the infrared code signal is transmitted from the infrared transmitter inside the equipment without using the remote control transmitter outside the equipment, one light-receiving unit can be shared. Therefore, it is equivalent to that the sum of the infrared ray amount as the natural energy from the outside of the device and the infrared ray amount as the infrared code signal from the inside of the device is input to the light receiving part,
For example, even if an infrared code signal from inside the device is input, if the amount of natural energy from outside the device is extremely large compared to the infrared code signal from inside the device, the amount of incident infrared light from outside the device is dominant. Then, the signal level becomes high, and the gain of the automatic gain control circuit section in the subsequent stage is also regulated. Therefore, the essential pulse code signal becomes extremely small without being amplified and does not reach the amplitude limit level in the limiter circuit part in the subsequent stage, and therefore a malfunction or instability occurs because it is input to the microcomputer as a minute signal amplitude. There is a problem of exhibiting motion.

Therefore, the present invention has been made in consideration of the above circumstances, and an object thereof is to provide an infrared code signal from an outside function path and an infrared code signal from an inside path of a device under any environment. It is an object to provide a control device that reliably selects and prevents malfunction or unstable operation.
