TITLE OF ~HE `INV~ION
STUDYING . TOOL
BACKGR<OUND OF ~H~ . XNV~ON
~ield of the Invention
The present inven~ion relates ~o a studying tool, and
more particularly, a page-releasable boo~ such as a
question-answer book.
Description of the Prior Arts
Students use workbooks to improve in their studies.
Conventional workbooks, for example, a question-answer book
are manufactured in hard cover with paper on which words of
questions and answe~s have been printed.
It is difficult to take out a sheet from the conven-
tional question-answer book. In order for the user to carry
with them only a page having questions and answers important
for the user, it is necessary to cut out the page, write
questions and answers on another sheet or copy them by a
copying machine. Doing so ta~es time and labor.
SUMMARY OF THE INVENT~ON
It is therefore the principal object of the present
invention to provide a studying tool allowing sheet materi-
als having necessary questions and answers to be torn off,
203~,09~
repeat~dly s.u~k to ~n article wi~rl ease, and ~hen adhered
to each.other after. they are torn off the article.
~ n accomplishing these and other.objects, a studying
tool according to the present invention compxises: a first
sheet material having a first printed layer., ~ormed on one
principal surface thereof, for showing a question and a
re-adhesive layer formed on the other princip~l surface
thereof; and a second sheet material having a second printed
layer, formed on one principal surface.thereof, for showing
an answer to the question and the re-adhesive layer formed
on the other principal surface thereof. In the above
construction, a plurality of the first sheet materials and
the second sheet materials are alternately adhered to each
other via the re-adhesive layer in such a manner that the
first sheet material covers the second sheet.material.
The first and second sheet materials torn off are
repeatedly adhered to an article.
~ ccording to.the present invention, the first and
second sheet material released from the studying tool can be
repeatedly stuck to an article with ease and then, torn off
the article. Thereafter, they are adhered to each other.
Therefore, the first and second shèet material having
~uestions and.answers important for the user are torn off
the studying tool and stuck to, for example, a pocket book.

Then, they can be adhered to each other and returned to the
original position of the studying tool as necessary.
These objects and other objects, features, aspects and
advantages of the present invention will become apparent
from the following detailed description of the embodiments
of the present invention when taken ln connection with the
accompanying drawings.

~ page-releasabl~ studying book 1~ as ~ studying tool
comprises a plur~lity of first sheet materials 12 and second
sheet materials 18 alternately adhered to each other via a
re-adhesive layer 14.
More specifically, the page-re~easable studying book 10
includes the rectangular first sheet material 12 consisting
of, for example, paper, synthetic paper or a synthetic resin
film.
The re-adhesive layer 14 is formed on one principal
surface of the first sheet material 12 by applying a wea~
pressure sensitive re-adhesive agent thereto.in such a
manner that the re-adhesive layer 14 has a predetermined
width and length in the vicinity of both ends o the first
sheet material 12 in the. longitudinal direction thereof.
Questions are printed on approximately the center of
the other principal surface of the first sheet material 12
by a ~nown printing machine. Thus, a first printed layer 16
is formed.
The page-releasable studying book 10 further includes
the rectangular second sheet material la having the same
width as the first sheet material 12 and being longer than
the first sheet material 12. The length of the second sheet
material 18 may be equal to that of the first.sheet material
12. The second sheet-material 18 consists of, for examplej
paper, synthetic paper or a synthe.tic resin film. The
203~9~
re-a~hes,~e layer 14 i~ dlso ~o~med by appi~ir~ a weak
p-Lessure sensltive re-adhesive agent ,to onc principal
surface of the, second.sheet material.~.8 in .such a manner
that the re-adhesive layer 14 has a predetermined width and
length i.n the. vicinity of both ends of the second sheet
material 18 in the longitudinal direction thereof.
Answers to questions are printed on approximately the
center of the other principal surface of the second.sheet
material 18 by.a known printing machine. Thus, .a second
printed layer 20 is formed.
T~,e first sheet material 12 is adhered to the second
sheet material 18 in such a manner that the first sheet
material 12 covers the second printed layer 20. The first
and second sheet materials 12 and 18 are adhered to each
other such that one of the ends .thereof .align with each
other in the longitudinal direction thereof.
Accordingly, the answers of the second printed layer 20
of the second.sheet material 18 are covered with the. first
sheet material 12.
In this manner, the page-releasable studying book lO is
formed by alternately laminating the.first and.second sheet
materials 12 and 18 with the re-adhesive layer 14.
According to the page-releasable studying book 10, as
shown in Fig. lB, the answer to the.question which have.been
printed on the first sheet material 12 can be seen by
203209~
tearing the second sheet materlal 1~ off the page-releasable
studying book 10.
Further, as shown in Fig. 3, when the user regards the
contents of the first and second sheet materials 12 and 18
as very important, the user can tear them off the page-re-
leasable studying book 10 and stick them, for example, to a
pocket book 30 via the re-adhesive layer 14. Thus, the user
can study at various places. As necessary, the first and
second sheet materials 12 and 18 may be torn off the pocket
book 30 and put back to the page-releasable studying book
10 .
It is possible to form a release layer on the other
principal surface of the first and second sheet materials 12
and 18 by applying a release agent such as silicon resin,
paraff.in or wax thereto in such a manner that the position
of the release layer corresponds to that of the re-adhesive
layer 14 formed on one principal surface thereof. The
release layer may be formed by sticking releasable paper or
a releasable film to the first and second sheet materials 12
and 18.
Although the present invention has been described and
illustrated in detail, it is clearly understood that the
same is by way of illustration and example only and is not
to be taken by way of limitation, the spirit and scope.of

the present invention being ~imited only by the terms of the
