PURPOSE:To obtain the electronic black board device of a built-in printing device type, in which a recording paper is easily exchanged by providing a notch or a hole at the terminating part of a sheet, and at the same time, installing a printing part in a cubicle corresponding to the position of the notch or the hole. CONSTITUTION:When the recording paper 6 is used up to a terminal, a detecting lever 19 rotates in the direction of an arrow mark A to a dotted line position. An end sensor 20 detects the terminal of the recording paper 6, and informs it to a controlling part 13 through a print controlling part 21. The controlling part 13 switches a switch 13a to a motor 12a, and makes the motor 11a rotate, and makes the sheet 5 move until a mark sensor 14 detects an end mark 15, and makes it stop, and makes the displaying means 9b of an operating part 9 light. An operator can exchange the recording paper 6 easily from a face side by taking out only the front face cover 2 of the printing device 2. The terminal part of the sheet 5 is formed so that a right side and lower part is diagonally cut into a notch part 5a, and the printing device 2 is installed at the rectangular notch part of a supporting plate 10 corresponding to the position of the right and lower part of the said right-angled triangle.
