摘要

The bookrest (1) has several ribs (10) with through apertures, through which an axial element (20) passes, and an arresting mechanism (30, 31) by means of which the ribs lined up on the axial element (which may be rigid or flexible) can be locked relative to each other. The arresting mechanism may include arresting holes through which an arresting bar can pass.
