• the interval adjusting shaft 156 is formed with a screw thread on an outer circumference thereof.
• the roller part 154 comprising a roller 154a is connected to one end of the interval adjusting shaft 156. The roller 154a rotates in contact with the base panel 110.
• the contact between the roller 154a and the base panel 110 can be achieved by rotating the interval adjusting shaft 156 having the screw thread. More specifically, when the interval adjusting shaft 156 is rotated in a certain direction, the roller 154a approaches the base panel 110. When the interval adjusting shaft 156 is rotated in the opposite direction, on the other hand, the roller 154a moves toward the supporting bracket 153. Therefore, a contacting degree of the roller 154a with respect to the base panel 110 can be controlled through rotation of the interval adjusting shaft 156.
• the writing panel 160 may be divided into at least two parts. A rear side of the writing panel 160 is in connection with the fixing bracket 152 while a front side is formed to perform writing thereon.
