Abstract

A substantially ring shaped resistor unit and an conductor unit with a certain space therebetween are provided under an operating unit having a substantially disc shape or a substantially ring shape. When an operating unit is depressed, the resistor unit and the conductor unit are contacted with each other at a position at which the depression is provided. Based on the contact, a controlling part detects the position at which the depression is provided, and a transmitting part transmits a remote control signal corresponding to the position at which the depression is provided.

Claims

1. A remote control transmitter, comprising:

a wiring board where electronic components for generating a remote control signal are mounted;

a housing for installing the wiring board;

an operating unit disposed at an upper face of the housing, an arbitrary portion of an outer part of the operating unit can be moved in a depressed direction;

a resistor unit and a conductor unit provided under the operating unit in parallel and opposed to each other with a certain space therebetween;

a controlling part electrically connected to the resistor unit and the conductor unit; and

a transmitting part for transmitting a remote control signal in response to an instruction from the controlling part,

wherein the remote control transmitter is structured such that, when the operating unit is depressed, the resistor unit and the conductor unit are contacted with each other at a position at which the depression is provided, and

wherein the controlling part electrically detects the position at which the resistor unit and the conductor unit are contacted with each other to instruct the transmitting part to transmit a remote control signal corresponding to the detected position.

2. The remote control transmitter according to claim 1,

wherein the operating unit has a substantially disc shape or a substantially ring shape;

the resistor unit has a substantially ring shape; and

the conductor unit has a substantially ring shape.

3. The remote control transmitter according to claim 2,

wherein the operating unit is provided at the upper face of the housing so as to be tilted in a direction along which the operating unit is depressed.

4. The remote control transmitter according to claim 3,

wherein the controlling part is electrically connected to a pair of outer part provided in one diameter direction of the resistor unit and another pair of outer part provided in another diameter direction substantially orthogonal to the one diameter direction;

and

when the resistor unit is contacted with the conductor unit, the controlling part detects a position at which the resistor unit is contacted with the conductor unit based on resistance between the conductor unit and the electrically connected each outer parts of the resistor unit.

5. The remote control transmitter according to claim 4,

wherein the controlling part applies a voltage to the pair of outer parts provided in one diameter direction of the resistor unit to measure a voltage outputted from the conductor unit, and also applies a voltage to the another pair of outer parts provided in another diameter direction substantially orthogonal to the one diameter direction of the resistor unit to measure a voltage outputted from the conductor unit and, when the resistor unit is contacted with the conductor unit, the controlling part detects a position at which the resistor unit is contacted with the conductor unit based on the measured voltages from the conductor unit.

6. The remote control transmitter according to claim 5,

wherein the resistor unit is confronted with and provided under the operating unit;

and

the conductor unit is confronted with and provided under the resistor unit.

7. The remote control transmitter according to claim 5,

wherein the conductor unit is confronted with and provided under the operating unit;

and

the resistor unit is confronted with and provided under the conductor unit.

8. The remote control transmitter according to claim 1,

wherein a depressible unit is provided at a center part of the operating unit.

9. A transmitting and receiving device, comprising:

the remote control transmitter according to claim 1 and a receiver having a reception part and a display part,

wherein, the remote control transmitter transmits a remote control signal by operating the operating unit, and

wherein the reception part of the receiver receives the remote control signal, and controls the display part based on the received remote control signal.
