150:

These and other objects and advantages of the present invention will become more apparent from the following detailed description of the present invention when taken in conjunction with the accompanying drawings.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a schematic block diagram of a character data scroll apparatus of a microwave oven according to a preferred embodiment of the present invention. The apparatus includes a speed control switch 110, a memory 120, a timer 130, a microcomputer 140, 150).

1, the speed control switch 110 provides a switching signal for controlling the scroll speed of character data to the microcomputer 140 on the basis of a user's operation signal, and the memory 120 stores various functions of the microwave oven The timer 130 counts the current time and provides the counted value to the microcomputer 140. [

Here, the character data stored in the memory 120 includes control bits (for example, scroll repetition, scroll end, next character data scroll, etc.) for controlling the scroll state of character data.

The microcomputer 140 receives the character data corresponding to the currently performed function of the microwave oven from the memory 120 and generates a control signal for displaying the character data on the display unit 150. Then, The microcomputer 140 generates a control signal for controlling the control bit to be scrolled according to the control bit and the microcomputer 140 adjusts the control bit through the speed control switch 110 using the current time counted by the timer 130, And generates a control signal for scrolling the character data one character at a time according to the scroll speed.

The display unit 150 displays character data from the memory 120 provided through the microcomputer 140 on the basis of a control signal for display from the microcomputer 140 and then outputs a scroll control signal The character data is scrolled and displayed one character at a time.

The operation of scrolling a character scroll device and characters of a microwave oven according to the present invention, which is made up of the above-described components, will be described in more detail with reference to FIG. 1 to FIG.

First, when the user operates the speed control switch 110 to set a desired scroll speed (step 202), a switching signal corresponding to the switching signal is provided from the speed control switch 110 to the microcomputer 140, The controller 150 fetches character data corresponding to a function currently performed by the microwave oven from the memory 120 and generates a control signal for displaying the character data in the display unit 150. [

The character data retrieved from the memory 120 based on the display control signal from the microcomputer 140 is provided to the display unit 150 through the microcomputer 140 and displayed through the display unit 150 At this time, the microcomputer 140 checks whether the character data fetched from the memory 120 is character data to be scrolled (step 208).

If it is determined in step 208 that the character data fetched from the memory 120 is character data to be scrolled, the microcomputer 140 checks the control bits included in the fetched character data (step 210).

If the control bits included in the character data are scrolling repeatedly as a result of the check in step 210, the process returns to step 204 to repeat the steps 204, 206, and 208. In step 210, If the control bit is the next character data scroll, the next character data stored in the memory 120 is fetched (step 216).

At this time, the microcomputer 140 compares the time counted by the timer 130 with the time corresponding to the scroll speed set through the speed control switch 110 (step 218), and the time counted by the timer 130 is controlled by the speed control The microcomputer 140 generates a control signal for scrolling the character data displayed on the display unit 150, if the time corresponding to the scroll speed set through the switch 110 is reached.

Accordingly, the current character data displayed on the display unit 150 is scrolled one character on the basis of the scroll control signal from the microcomputer 140, and one character of the next character data fetched from the memory 120 is displayed on the display unit 150 (Steps 220 and 222).

As a result of the control bit check in step 210, if the control bit included in the character data is scrolled, the microcomputer 120 generates a control signal for stopping the scrolling of the character data, If the control bit is not the scroll end, the process returns to step 210 and repeats steps 210-222.

If the current character data is character data to be scrolled while the current character data on the function currently being performed by the microwave oven is extracted from the memory 120 and displayed on the display unit 150, The scroll control signal from the microcomputer 140 based on the control bit contained in the character data is displayed on the display unit 150 while being scrolled by one character on the basis of the scroll control signal from the microcomputer 140. In this case, Is controlled. On the other hand, the scroll speed of the character data is determined based on the switching signal from the speed adjustment switch 110 controlled by the user.

Meanwhile, in the embodiment of the present invention, the operation of scrolling the current character data or the next character data one character at a time is mainly described, but a person skilled in the art may refer to the display unit 150 It is easy to see that the character data can be blinked.

Therefore, by using the present invention, character data is displayed on the display unit 150 while being scrolled at predetermined time intervals, so that not only character data for each function of the microwave oven can be displayed in various ways, There is an advantage.
