DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an information receiving apparatus for receiving character information transmitted from an external information transmitting apparatus by using radio waves of teletext broadcasting.

[0002]

2. Description of the Related Art Conventionally, in text multiplex broadcasting using FM radio waves or the like, information transmitted from an information transmitting apparatus is defined as one screen composed of a fixed format (for example, three lines of 15 characters per line). Are set, and one program is composed of a plurality of pages. In this case, the first line of the above-mentioned page is used as a header for displaying a source of information, etc., as 2,
The third line is used as a text for displaying the content of the information.

On the other hand, recently, as a receiving apparatus for receiving the transmitted character information, a memory function for storing the received information, a function for calling and displaying the stored contents,
A product having various functions such as a function of switching between a normal three-line display screen mode and a four-line display screen mode for displaying two pages of text on one screen has been commercialized.

[0004]

However, in the case where the receiving apparatus is provided with various functions, if an operation switch is provided for each function, the number of switches increases, the size of the apparatus itself increases, and the cost increases. There's a problem.

In order not to increase the number of switches,
By operating a plurality of existing switches in a predetermined order,
If the two functions are realized, the number of operations increases, and the operation becomes complicated.

The present invention has been made in view of the above problems, and has as its object to provide an information receiving apparatus that can prevent an increase in the number of switches and a complicated operation even when various functions are provided. I have.

[0007]

As shown in FIG. 9, the invention according to claim 1 is an information receiving apparatus for receiving character information transmitted from an external information transmitting apparatus 3 using a radio wave of a text multiplex broadcast. 2, a receiving means 50 for receiving the transmitted character information, a display means 51 for displaying the received character information, a function setting means 52 for assigning a predetermined function to a predetermined operation switch, A display control means 53 for displaying the contents of the function on the display means, and a function setting control means 54 for changing the contents of the function assignment by the setting means.

According to a second aspect of the present invention, in the first aspect, the display control means 53 displays the assignment of the function together with the character information received by the receiving means 50.
1 is displayed.

[0009]

According to the information receiving apparatus of the first aspect, the character information received by the receiving means is displayed on the display means. A predetermined function is assigned to a predetermined operation switch by the function setting means 52, and the contents of this function are displayed on the display means 51 by the display control means 53. Further, the contents of the above functions are changed by the function setting control means 54.

As described above, an arbitrary function is assigned to the operation switch and changed, so that it is possible to prevent the number of operation switches from increasing with an increase in the functions of the receiving device, and to prevent an increase in cost. In addition, since the content of the assigned function is displayed, there is an effect that the operation can be easily performed.

According to the information receiving apparatus of the second aspect, the function contents assigned to the operation switches are displayed on the display means 51 together with the character information by the display control means 53.

As described above, the function contents of the operation switch are displayed together with the received character information. Therefore, when the function of the switch is changed, it is possible to respond only by changing the display contents. For example, engraving, screen printing, etc. The nameplate with
Since the space for attaching the panel can be eliminated, labor and cost can be reduced.
