Next, the detailed operation of FIG. 1 will be explained by taking the cases of FIGS. 2A and 3A as examples. First, start address a of sentence block A.

The end address b and pause time α are stored in the memory section (7b).
, (7c), (7d) area BG, , E Dl % P
S, -4-1 are read out and placed in the start address setting means (52), the end address setting means (53) and the pause time setting means (54). Then, the start address a of the start address setting means (52) is loaded into the address counting means (10). Also, the pause time α of the pause time setting means (54) is loaded into the pause time counting means (55). Then, by supplying a clock signal from the AND gate (57) to this address counting means (10), this is counted so as to add this from address a, and accordingly, RAM (
9), sentence block A is read out. Then, in the comparison means (56), the address counting means (1
0) and the end address b of the end address setting means (53) are compared, and if they match, a matching output is obtained from the comparing means (56) and supplied to the control means (50), As a result, a control signal is obtained from the control means (50), the AND gate (57) is turned off, the address counting means (10) stops counting, and the pause counting means (55) turns off the AND gate (58). This is counted to be subtracted from the initial value α by the clock signal from B, and when the count content of A reaches O, the start address b+1, end address C, and pause time β of sentence block B are stored in the memory section. Regions BG, , ED, , PS in (7b), (7c), and (7d).

Street → Read from 〒 and start address setting means (52)
, are respectively set in the end address setting means (53) and the pause time setting means (54). Then, the same operation as described above is repeated for the next sentence block B1.

Note that the sentence number stored in the memory section (7a) is displayed on the display device (12) or (22).

Note that the number of times the sentence blocks are divided and the number of times they are grouped is arbitrary, and it is also possible to perform these processes overlappingly. Furthermore, the value of the number n of storage areas is arbitrary, and when this n is small, the contents of the storage area are erased and a new sentence number, start address, end address, and pause time are written in each storage area. You can also do it.

〔Effect of the invention〕

According to the present invention described above, it is possible to obtain a learning material creation device that can easily combine a plurality of sentences or separate sentences.
