    • A marker device is disclosed which is of the type in which marks are recorded by creating points or lines of contact between two adjacent layers (1,2,130,140), and erasure is effected by separating said layers by effecting relative movement between a cursor (41,125,126) and said layers. The device comprises a cursor which forms one limb of a frame (4,120); and the central open part of said frame defines the area (45) where marks can be recorded. In one embodiment, the frame is disposed between the working layers and is withdrawn from the body of the device to effect erasure. In a second embodiment, the frame includes a front portion (124) having two bars (125,126) which define between them a slot (127); the upper of the working layers passes through the slot, and erasure is effected by drawing the layers out of the frame so that the upper layer passes over one of the bars and under the other.
    • 公开了一种标记装置,其是通过在两个相邻层(1,2,130,140)之间产生点或接触线来记录标记的类型,并且通过实现光标(41,125,126)之间的相对移动来分离所述层来实现擦除, 和所述层。 该装置包括形成框架(4,120)的一个肢体的光标; 并且所述框架的中央开口部分限定可以记录标记的区域(45)。 在一个实施例中,框架设置在工作层之间并且从设备的主体中取出以实现擦除。 在第二实施例中,框架包括具有两个杆(125,126)的前部(124),它们在它们之间限定一个狭槽(127); 工作层的上部通过狭槽,并且通过将层从框架中拉出来使得上层通过其中一个杆并且在另一个之上。
