An indexing line guide for a copy stand having an upright pallet for supporting sheets with horizontal lines of text to be copied. The pallet has a guide rail along one side edge, the rail having a row of rack teeth on the rearward side. A slide is received on and secured to the rail for longitudinal movement, the slide including a line guide that extends over and parallel to the lines of text on the sheet. The slide has an escapement that cooperates with the rack teeth as the guide rail and which is actuated by a lever adapted to be tapped by the user. When the lever is actuated, a pair of teeth in the escapement reverse their relation to the rack teeth momentarily and then reengage the rack teeth at the next lower position. With this operation, the line guide is repositioned immediately below the next line of text on the sheet to be copied.
