Abstract

An annular operation unit is formed as an outer shape to cover entire outline of a surface of a case, and inputting switches and displaying unit are attached inside of an opening at the center side of the annular operation unit, allowing the annular operation unit to have a size to perform fine rotational operations in case the entire size of the remote control transmitting device is miniaturized.

Claims

1. A remote control transmitting device comprising:

a case;

an operating unit rotatably attached to the case;

rotation detecting device detecting an angle of rotation of the operating unit around a rotation center axis;

a displaying unit displaying a plurality of control content that controls a controlled device;

an operating signal generating device generating control data for controlling the controlled device using selected control content, from the angle of rotation detected; and

a transmission device transmitting control data to the controlled device;

wherein the operating unit is attached to the case so as to cover the entire outline of a surface of the case; and

wherein the displaying unit is attached to a case disposed inside of the surface outline of the operation unit.

2. The remote control transmitting device as set forth in claim 1, wherein:

the outline of a surface of the case is formed in a circle; and

the operating unit is guided rotatably by a guiding unit formed along the circle outline of the case.

3. A remote control transmitting device comprising:

a case;

an annular operating unit rotatably attached to the case;

rotation detecting device detecting an angle of rotation of the annular operating unit around a rotation center axis;

a displaying unit for displaying a plurality of control content that controls a controlled device;

an inputting switch, connected to the case, for selecting, by an inputting operation, specific control content from a plurality of control content that is displayed on the displaying unit;

an operating signal generating device generating control data for controlling the controlled device using selected control content, from the angle of rotation detected by the rotation detecting device, in a control mode wherein specific control content has been selected by an inputting operation of the inputting switch; and

a transmission device transmitting control data to the controlled device;

wherein the annular operating unit attached to the case so as to cover the entire outline of a surface of the case; and

wherein the inputting switch and displaying unit attached to a surface of a case that is exposed to an opening at the rotational center side of the annular operation unit.

4. The remote control transmitting device as set forth in claim 3, wherein:

the case has a large diameter disc portion and a small diameter disc portion disposed on the same center line of the large-diameter disc unit at the upper side of the surface of the large diameter disc portion; and

the annular operation unit is rotatably attached around a rotation center axis of the annular operating unit, between a first ring guide unit formed downward along the outer peripheral edge of the small diameter disc portion and a second ring guide unit that is formed upward along the outer peripheral edge of the large diameter disc portion.

5. The remote control transmitting device as set forth in claim 3, wherein:

the case has two or more annular operation units each of which is attached separately and rotatably in rotation around the same rotation center axis, and, has a plurality of rotation angle detecting devices, per each annular operation unit, detecting the rotation angle of the annular operating unit around a rotation center axis; and

the entire outline of the surface of the case is covered by an annular operation unit having the largest diameter among the plurality of the annular operating units; and

the inputting switch and displaying unit are attached to a surface exposed to an opening at the center side of the annular operation unit having the smallest diameter.

6. The remote control transmitting device as set forth in claim 3, further comprising:

a luminescent displaying device installed to the annular operating units; and

wherein the luminescent displaying device produces luminescence in variant colors by control content selected by inputting operation.

7. The remote control transmitting device as set forth in claim 3, wherein:

the rotation detecting device detects the direction and angle of rotation of the annular operating units around a rotation center axis; and

the operating signal generating device generates control data for operating the controlled device rotationally using selected control content, from the direction and angle of rotation detected by the rotation detecting device, in a control mode wherein control content to operate rotationally the controlled device has been selected.

8. The remote control transmitting device as set forth in claim 7, further comprising:

a guide displaying device installed to the annular operation, said guide displaying device displaying a direction of rotation of the controlled device in a control mode wherein control content to operate the controlled device rotationally is selected; and

in said control mode, when annular operation units are operated rotationally in a direction of rotation displayed by the guide displaying device, the operating signal generating device generates control data for controlling the rotation of controlled device in a rotational operation direction displayed by the guide displaying device using a rotating direction and an angle detected by rotation angle detecting device.

9. The remote control transmitting device as set forth in claim 3, wherein:

the transmission device is a RF transmitting module which transmits control data to the controlled device using RF signals.
