ledger sheet 9 or other sheet beneath which the sheet 1
and strip 20 are positioned in use. Moreover, the ?exible
line guide 10 is of a character to conform to the ledger
sheet over which it is disposed and electrostatically to hug
the same.
A hold down bar 24 comprises a generally channel
shaped plastic member 215, formed, for example, of Vinyl‘
ite, with closed ends 26 and an open bottom 27. Plastic
walls 28 extend transversely between the side walls 29,
which are closed at the top. The walls 28 are in spaced
relation with regard to the closed ends 26 and form pock
ets 30. A magnet bar 32 is secured within each pocket 30
and these magnet bars 32 are exposed through the open
bottom 27 of the generally channel-shaped member 25.
Thus, when the copyholder is slipped into the ledger,
as shown fragmentarily in FIGURE 6, and the open bot
tom of the bar 29 is placed over the upper margin of the
ledger sheet 9 and upon the metallic strip 20, as shown
in FIGURE 6 with the ledger sheet in place, and in FIG
