[0017]
(Embodiment 1)
FIG. 1 is a top view showing a configuration of a remote control device using the operating device according to the first embodiment of the present invention, FIG. 2 is an exploded perspective view of the operating device in the same embodiment, and FIG. FIG. 4 shows a bottom view of the jog shuttle. In FIG. 1, reference numeral 1 denotes a remote controller that transmits a control signal to a controlled device such as a video tape recorder by a wireless signal such as an infrared ray, and 2 is an operation button that can perform various operations such as setting of reserved recording and playback / fast-forwarding. Thus, a plurality of remote controllers 1 are provided on the top surface or the back surface. Reference numeral 3 denotes a jog shuttle which is a rotation operation means that can perform operations such as fast-forward reproduction and frame advance by rotating clockwise or counterclockwise as indicated by an arrow A. On the inner surface of the jog shuttle, as shown in FIG. A protrusion 3a is provided. When the jog shuttle 3 rotates, the protrusion 3a contacts the switch 6 and repeats the ON / OFF operation. 4 is a sensor which is a detecting means provided on the upper surface of the jog shuttle 3, and the shape is slightly depressed so that the user's finger can be inserted, and the user can easily transmit the rotational force to the jog shuttle 3. I am doing so. The sensor 4 detects that a part of the user's body (finger in this example) is touched, and switches between jog operation and shuttle operation according to the detection result. ing. Further, as a sensor device used for this sensor, a temperature sensor by temperature detection, a pressure sensor for detecting a finger pressing force, or the like was used. In the present embodiment, the jog mode is set when the sensor 4 detects a contact state of a finger or the like, and the shuttle mode is set when the sensor 4 does not detect it. This is also one of the embodiments, and may be set to the shuttle mode when the sensor 4 detects it and to the jog mode when it is not detected.
[0018]
In FIG. 2, reference numeral 5 denotes a printed circuit board on which the jog shuttle 3 and other circuits are mounted, and reference numeral 6 denotes a plurality of protrusions 3 a provided on the inner surface of the jog shuttle 3 as the jog shuttle 3 rotates. It is a switch that performs an OFF switching operation. Here, the switch 6 is a switch that is OFF in a normal state and can be turned ON in two directions, such as a 2-way detector switch. This switch is merely an embodiment, and it goes without saying that other switches may be used as long as they perform the same operation.
[0019]
Here, the jog mode means that the user touches the sensor 4 to enter the jog mode, and the jog shuttle 3 is rotated so that the projection 3a turns on the switch 6 once so that the television image is received. In this mode, the video on the device can be sent one frame (one frame) forward or backward. The shuttle mode is a mode in which the user can perform fast forward playback, rewind playback, slow playback, and the like by rotating the jog shuttle 3 without touching the sensor 4. The speed can be varied in 7 steps from slow playback to fast forward playback.
[0020]
For example, when the jog shuttle 3 is slightly rotated in the forward direction and the projection 3a turns on the switch 6 once, slow playback at the lowest speed starts on the screen, and further rotation causes the second projection to switch the switch 6 on. When turned on for the second time, slow playback is performed at a speed slightly faster than the slow playback described above. Similarly, faster slow playback at the third time, normal playback at the fourth time, fast forward playback at slightly higher speed at the fifth time, and fast forward playback that becomes faster at the sixth time and the seventh time are performed. In this embodiment, a total of seven steps of variable speed reproduction is possible, but the number of steps is not limited to seven. In addition, the jog shuttle 3 is configured to rotate once in the forward direction and in the reverse direction. In the jog mode, an infinite number of frames can be fed as long as there is a tape, but in the shuttle mode, Only the number of steps set in advance can be operated, and even if an operation exceeding the setting is performed, the operation is fixed at the maximum speed (fast forward playback at the highest speed) or at the lowest speed (slow playback at the lowest speed).

Reference numeral 36 denotes an operation unit that is an operation unit that controls the operation of the internal circuit based on the jog signal from the jog signal generation unit 34 or the shuttle signal from the shuttle signal generation unit 35.
[0022]
The operation of the operation device of the present embodiment configured as described above will be described below.
[0023]
First, the operation in the jog mode will be described.
[0024]
The jog mode can be operated by rotating the jog shuttle 3 clockwise or counterclockwise with the sensor 4 provided on the upper surface of the jog shuttle 3 detecting that the finger of the user has touched. it can.
[0025]
First, the video tape is set to the playback mode by pressing the playback button in the operation button 2 of the remote controller 1. When the jog shuttle 3 is slightly rotated clockwise from this state, the protrusion 3a turns on the switch 6 once. Then, on the screen of the television receiver, the image being reproduced is temporarily stopped as a still image. Further, when the jog shuttle 3 is slightly rotated in the clockwise direction and the second protrusion 3a performs the second ON operation of the switch 6, an image is sent by one frame on the screen. Similarly, when the jog shuttle 3 is rotated, every time the projection 3a turns on the switch 6, the image is sent one frame at a time. So-called frame-by-frame playback is possible. Similarly, when the jog shuttle 3 is rotated in the counterclockwise direction, the projection is operated to turn on the switch 6 in the reverse direction, whereby an image is sent one frame at a time in the reverse direction.
[0026]
The above operation will be described with reference to FIG. First, when it is detected that the user has touched the sensor 31, the detection signal is input to the control unit 33. When the user rotates the jog shuttle, the switch 32 is turned on and the signal is input to the control unit 33. Since both signals from the sensor 31 and the switch 32 are input, the control unit 33 determines that the jog mode is selected, and outputs a control signal to the jog signal generation unit 34 so as to generate a jog signal. The jog signal generation unit 34 generates a jog signal for performing a frame advance operation based on the control signal and outputs the jog signal to the operation unit 36. The operation unit 36 performs a frame advance operation on an internal circuit or mechanism by the jog signal. Control the behavior to do.
[0027]
Next, the operation in the shuttle mode will be described.

The shuttle mode can be operated by rotating the jog shuttle 3 clockwise or counterclockwise while the user does not touch the sensor 4.
[0029]
First, the playback button in the operation button 2 is operated to bring the video tape into a playback state, and then when the jog shuttle 3 is slightly rotated clockwise, the first protrusion 3a turns on the switch 6 for the first time. At this time, the shuttle mode is turned ON, and slow playback at the lowest speed starts on the screen of the television receiver. When the jog shuttle 3 is further rotated in the clockwise direction and the second protrusion 3a turns the switch 6 to the second ON state, the slow reproduction is performed slightly faster than the slow reproduction described above. In the same manner, even faster playback is performed by the third switching operation, and normal playback is performed by the fourth switching operation. Further, when the jog shuttle 3 is rotated and the fifth switching operation is performed, fast-forward playback is performed faster than normal playback. Faster fast-forward playback can be performed by the sixth switching operation, and fast-forward playback at the maximum speed can be performed by the seventh switching operation.
[0030]
The above operation will be described with reference to FIG. First, when the user rotates the jog shuttle without detecting that the user touches the sensor 31, the switch 32 is turned ON, and only the signal from the switch 32 is input to the control unit 33. Since only the signal from the switch 32 is input, the control unit 33 determines that the mode is the shuttle mode, and outputs a control signal to the shuttle signal generation unit 35 so as to generate a shuttle signal. The shuttle signal generator 35 generates a shuttle signal for performing a shuttle operation such as fast forward / rewind playback or slow playback based on the control signal, and outputs the shuttle signal to the operating unit 36. The operating unit 36 uses the shuttle signal to generate an internal circuit. And the mechanism are controlled to perform operations such as fast forward / rewind playback and slow playback.
[0031]
In this embodiment, since variable speed playback is performed in a total of seven stages, ie, three slow stages, three fast-forward playback stages, and normal playback, the jog shuttle 3 is further rotated in the fast-forward playback at the highest speed in the seventh stage. However, the maximum speed remains fixed.
[0032]
On the other hand, when the jog shuttle 3 is rotated in the counterclockwise direction from the normal playback state, reverse slow playback starts, and the switch 6 is switched in the counterclockwise direction by further rotating in the counterclockwise direction. In addition, it is possible to perform reverse-shifted reproduction in a total of seven stages including normal reverse reproduction and three-stage rewind reproduction. Also in this example, the reverse-shifted reproduction is performed in seven stages, and even if the jog shuttle 3 is further rotated counterclockwise from the highest-speed rewind reproduction state, the highest-speed rewind reproduction remains the fixed speed. . When the shuttle mode is to be canceled, it is reset by pressing, for example, the playback button in the operation button 2.
[0033]
As described above, according to the present embodiment, the sensor 4 is provided on the upper surface of the jog shuttle 3 to detect whether or not the user is touching and to switch between the jog mode and the shuttle mode. Thus, the operability can be improved, the configuration can be simplified, and the apparatus can be downsized. In addition, since the sensor 4 is provided in the indentation for jog operation that has been conventionally provided, it is not necessary to provide a space for the sensor on the jog shuttle, and the size of the apparatus is not increased.
[0034]
In this embodiment, the sensor is provided on the upper surface of the jog shuttle. However, the position where the sensor is provided is not limited to the upper surface of the jog shuttle. For example, the entire circumference of the side surface of the jog shuttle is used as a sensor. Even if the operation is detected, the operability can be improved.

The sensor 12 detects that a part of the user's body (finger in this example) is touched, and switches between jog operation and shuttle operation according to the detection result. ing. Furthermore, as a sensor device used for the sensor 12, a temperature sensor by temperature detection, a pressure sensor for detecting a finger pressing force, or the like was used. In the present embodiment, the jog mode is selected when the sensor 12 detects a contact state of a finger or the like, and the shuttle mode is selected when no contact is detected. This is also one of the embodiments, and may be set to the shuttle mode when the sensor 4 detects it and to the jog mode when it is not detected.

Further, when the jog shuttle 11 is slightly rotated in the clockwise direction and the second protrusion 3a performs the second ON operation with respect to the switch 6, an image is sent by one frame on the screen. Similarly, when the jog shuttle 11 is rotated, every time the projection 3a turns on the switch 6, an image is sent one frame at a time. So-called frame-by-frame playback is possible. Similarly, when the jog shuttle 11 is rotated in the counterclockwise direction, the projections turn on the switch 6 in the reverse direction, whereby images are sent one frame at a time in the reverse direction.
[0040]
