Claims

[Scope of utility model registration request]

a character extraction control unit for extracting a character program multiplexed during a vertical blanking period of a television signal; a number designating key part for designating a character program number to both sides;
A display memory for one screen is connected to the control unit and stores a designated text program, and under the control of the control unit, the text program stored in the display memory is transferred to the display unit and displayed. In the teletext broadcasting receiver, there is provided a removable multi-page memory section connected to the control section and containing one or more page memories for one screen, and a number of a text program is stored in each of the page memories. A preset memory, a dedicated switch unit having dedicated switches corresponding to the number of the page memories, a command switch unit having a preset command switch for the preset memory, and a command switch unit that detects attachment/detachment of the multi-page memory unit and attaches the unit to the control unit. an attachment/detachment detection section that outputs a detection signal or a detachment detection signal, and outputs a character program numbered in the preset memory to the page memory when the attachment detection signal is input to the control section; means for transferring the character program in the page memory to the display memory by operating the dedicated switch when the wearing detection signal is input; and display output means for outputting the text program numbered in the preset memory to the display memory.
