Abstract
A two-way positionable copyholder is provided. A copy support member of the copyholder which receives a document to be transcribed is manually raiseable or lowerable and forwardly or rearwardly tiltable. To this end, the copyholder is provided with a slidable front support leg and a pivotable rear support leg. The front supporting leg engages a rear side of the copy support member, and the pivoting rear supporting leg mounts to the front support leg. A connecting member or tension bar connects the front and rear legs together. A forward end of the connecting member is pivotally mounted to the sliding support leg, whereas a rear or free end of the connecting member is detachably mounted at selected positions along the rear pivoting leg. The height of the copy support member is varied by sliding the front leg with respect to the support member. The angle or tilt of the copy support member is varied by repositioning the free end of the connecting member along the rear leg.
