Specifically, 50
Display of phonetic character table Display the character table with the call key, move the pointer in the character table with the cross key, and select and enter the selected character with the enter key.

In addition to the remote controller, a touch panel such as a liquid crystal and an input pen are used to input characters by handwriting or display a list of characters in two steps on the screen for input (JP-A-6-202784). Device, etc.). Further, as a general technique, there is an input device using a character keyboard.

On the other hand, although it is not specialized for the purpose of character input, as a function of the remote controller, a device for detecting the angle of the remote controller and setting the operation mode for the purpose of reducing the number of buttons on the remote controller 6-7388).

[0005]

The conventional character input using the ten-character key requires a large screen space for displaying a list of characters on the screen. As a result, it is difficult to edit the text because the text of the input characters is hidden, and other information such as a video cannot be displayed on the same screen separately from other character input. Further, finding a specific character from a list showing a large number of characters is difficult to perform visually without complicated operation.

Further, a touch panel type device using a keyboard, a liquid crystal or the like as means other than the remote controller (Japanese Patent Laid-Open No.
202784), the cost of commercialization is higher than that of the present invention using a remote controller, and the operation is based on the assumption that a small device such as a mobile terminal is used. Not suitable for use in typing.

Further, in a device (described in Japanese Utility Model Laid-Open No. 6-7388) in which operation is performed by tilting the remote controller for the purpose of reducing the number of buttons on the remote controller, two or more light sources having different wavelengths for reception and transmission are provided. Since it has to be used (requires four or more light sources for each transmission and reception), both the light emitting and receiving parts are costly and the device volume is large, which is a burden for small equipment such as remote controllers. Not suitable.

DESCRIPTION OF THE PREFERRED EMBODIMENTS First, the outline of the present invention will be described with reference to FIG. When the cursor is moved by tilting the remote controller 12, the light emitting unit of the remote controller 12 is provided with one LED or the like having high output and narrow directional angle characteristics. The light receiving unit 8 has two light receiving elements (A,
B) Prepare. In that case, the positions of the two light receiving elements (A, B) are set so as to satisfy the condition that the difference between the gains of the signals from the light emitting units is detected. Further, when the cursor is moved by shaking the remote controller 12 not to the up and down but to the left and right, two light receiving elements having the same wavelength may be provided in the left and right direction.

Embodiments of the present invention will be specifically described below. FIG. 1 is a system configuration diagram of the present invention, FIG. 2 is a block diagram, and FIG. 3 is a diagram showing a display example on a screen of a television or the like.

<Embodiment 1> When the display request button of the character line "Akasata ..." On the remote controller 10 of FIG. 1 is pressed, the light receiving portion 8 of the display 9 receives the transmission code and the character based on the code is received. Information of a plurality of characters such as lines and cursors is displayed on the screen from the storage unit 1 and the call display unit 4. At this time, it is displayed on the display unit 4 as shown in FIG. Also, when the character line display request button is pressed again, the character line disappears.

Next, press the up / down button to move the cursor 13
While moving up and down, when a character is selected from the displayed characters by the control unit 3 and the selection confirmation key is pressed, the selected character is input to the character input editing unit 5. Repeat this operation to enter characters.

In the case of a TV remote controller, it is also used as a channel setting button. For example, 1 → a, 2 →, 3 → sa ...

<Embodiment 2> In FIG. 1, a button indicating a character line "Akasata ..." On the remote controller 11 is pressed and the transmission code when the button is pressed is received by two light receiving elements. In the case of the TV remote controller 11, it is also used as a channel setting button. For example, 1 → a 2 → or 3
→ Say ...

A character line and a cursor based on the code are displayed as in the first embodiment.

Next, by tilting the remote controller 11 up and down while pressing the display button of the character line "Akasata ...", the tilt is detected by the analysis unit 2 and the cursor 13 is moved up and down by the control unit 3. Move to. By doing so, a character is selected from the displayed characters, and the character is input when the display button is released. Repeat this operation to enter characters.
At this time, the moving speed of the cursor can be arbitrarily adjusted by the cursor moving speed adjusting volume 6.

A technique for sensing the vertical tilt of the remote controllers 10 and 11 in the first and second embodiments described above on the side of the television or the like is shown in FIGS.

In FIG. 4, the amount of light received by the light receiving element A>
In the case of the amount of light received in the light receiving element B, the signal going from the analysis unit 2 to the control unit 3 in FIG. 2 becomes "1", and the cursor keeps moving upward. In the opposite case (A <B), the signal goes to "0" and the cursor continues to move down.

If the volume of the cursor moving speed adjusting volume 6 shown in FIG. 2 is raised, the moving speed of the cursor 13 becomes faster. Similarly, lowering it will slow it down. By setting this speed arbitrarily, it becomes easier to specify the character of the cursor (select the character when the button is released when the cursor matches the desired character).
