The lower engaging projection (36) is engaged with the engaging portion (37) on the lower end surface of the fitting portion (20), and the lower edge of the blackboard body (1) is attached to the tray ( 8) is fitted in the fitting groove (11), and then the left and right ends of the tray (8) are connected to the end cover (2).
The blackboard is inserted by intervening in the intervention hole (28) and the front band fitting recess (29) of 2) and inserting the screw (32) into the insertion hole (33) and the screw insertion hole (21) in this state. The saucer (8) and the end cover (22) are integrally mounted on the main body (1). In this way, the left and right end surfaces of the front cover (34) and the end surface of the front fitting recess (29) of the end cover (22) are in contact with each other, and
The peripheral edge of the tray (8) is covered with the front cover (34) and the pair of end covers (22) in a state where the recess (25) is aligned with the surface of the dish (17). Chalk storage boxes (38)
Is placed on the receiving tray (8) so that the lower surface of the sweep plate (44) contacts the upper surface of the dish portion (17). In this case, the collar (4
2) and (42) slightly float above the receiving piece (16) and the front cover (34). Also, when attaching the dust collector (45),
First, the locking projection (49) is locked to the outer edge of the lower plate (23) of the end cover (22), and the entire dust catcher (45) is turned forward with the locking part as a fulcrum. Locking part (50) by moving
By this, the end cover (22) is sandwiched in the front-rear direction, and the contact portion (51) is pressed against the surface of the tray (8).

The upper surface of the piece (16) and the upper surface of the front cover (34) are in contact with each other. Then, the lower surface of the sweep plate (44) closely contacts the upper surface of the dish (17) without any gap,
In this state, the choke storage box (38) is slid toward one end where the dust collector (45) is attached. Then, the sweep plate (44)
Thereby, the powder P of chalk is swept and collected, and the powder P is stored in the powder catcher (45) via the pressure contact portion (51). Next, the dust catcher (45) is pivoted upward and rearward with the engaging portion between the engaging projection (49) and the outer edge of the lower surface plate (23) of the end cover (22) as a fulcrum to clamp it. The part (50) is to be removed from the end cover (22).

有する。As described above, according to the present invention, it is possible to efficiently sweep and collect the chalk powder collected in the saucer and store it in the dust collector, and the chalk storage box with respect to the end cover of the saucer. Since it is removable, the dust collector can be selectively attached to either the left or right end cover of the saucer, which is extremely advantageous for use, and there is a risk that chalk powder will scatter even when it is removed. It is also convenient when cleaning itself and the end of the pan by removing the dust remover.Moreover, the front opening of the storage part is inclined upward, so that the choke It is easy to put powder, and furthermore, the choke storage box is provided with sweeping plates on the left and right side surfaces of the container, that is, on both side surfaces in the direction of sliding with respect to the pan so that the lower surface of the sweep plate protrudes from the bottom surface of the container. Chalk It has the advantage that powder can be effectively swept out.
