PROBLEM TO BE SOLVED: To write on a blackboard with a proper time distribution.SOLUTION: An electronic blackboard 3 comprises: a display part 31; pieces of writing data D in which a content which should be written on the blackboard in a single lesson is allocated, respectively; a writing database 242 for storing a writing plan file F, in which a writing order of the pieces of writing data D and an allocation time allocated from a lesson time as a duration for handling the content of each writing data D, are associated and stored; a CPU 35 for measuring a lapse time of lesson; and an input part 32 for inputting the writing content on the basis of a user operation, and displaying the same on the display part 31. The CPU 35 detects the writing data D corresponding to the input writing content, from the writing plan file F, then, based on the measured lapse time and the writing order and the allocation time of the pieces of writing data D, detects the writing data D of the content which should be written on the blackboard at a current time point, then when the pieces of detected writing data D do not match, notifies a user of the fact.SELECTED DRAWING: Figure 13 |
