  This multi-functional board surface was developed by the applicant of the present application, and the writing surface is a light color suitable for use as a screen, and the surface roughness is a range suitable for the use of chalk and markers and for wiping them. Therefore, it can be used as a chalk board, marker board, or even a screen with a single writing surface.

  The type of the board surface 7a of the sub board 7 arranged on the front side of the main board 1 is the same as that of the board surface 1a of the main board 1, and various combinations of the types of the board surfaces 1a and 7a are selected. Can do. The main board 1 and the sub board 7 are usually different types, but may be the same type. As a preferable or general combination, it is conceivable that the main board 1 is a blackboard or white board and the sub board 7 is an electronic board or screen.

  In the present invention, the sub board 7 is configured to be movable to an arbitrary position on the main board 1. For this purpose, guide rails 4 and 5 are provided along the upper and lower frames of the main board 1, and the sub board 7 is engaged with the upper and lower guide rails 4 and 5 to roll or slide. It is conceivable to install the sub board 7 by attaching rail engaging means and engaging the rail engaging means with the guide rails 4 and 5.

  Various combinations of the guide rails 4 and 5 and the rail engaging means which is a rolling means or sliding means for the guide rails 4 and 5 are conceivable, but a preferable or general combination is a guide rail having a C-shaped cross section. It is conceivable to engage the rolling wheel 8 with 4, 5 (see FIG. 2). The rolling wheel 8 preferably has a shaft 11 fixed to the upper frame 9 and the lower frame 10 of the sub board 7, and a wheel mounting plate 12 which is rotatable in the horizontal direction together with the shaft 11 at the lower end of the shaft 11.
