Abstract
Abstract A therapeutic educational tracing device consisting of a transparent panel having an eraseable surface, a transparency bearing indicia removably disposed to underlie the panel, a rearwardly disposed mirror angled to reflect the indicia and thus enable a child tracing the indicia to perceive his hand and the indicia in the mirror and perceptually guide his hand in tracing the indicia by a mental process.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
103 words
A perceptual educational tracing apparatus, having in combination a transparent panel member, a transparent sheet member bearing indicia, means removably holding said transparent sheet member to underlay said transparent panel member, a panel member having a mirrored surface, and means adjustably securing said first and second mentioned panel members relative to each other for reflection of said indicia upon said mirrored surface, whereby there is direct observation of the hand of the operator in tracing said indicia and an observation of said hand as a mirrored image for perceptual guidance of said hand in tracing said indicia as seen upon said mirrored surface.
Claim 2
Dependent Claim
103 words
A perceptual educational tracing apparatus, having in combination a transparent panel member, a transparent sheet member bearing indicia, means removably holding said transparent sheet member to underlay said transparent panel member, a panel member having a mirrored surface, and means adjustably securing said first and second mentioned panel members relative to each other for reflection of said indicia upon said mirrored surface, whereby there is direct observation of the hand of the operator in tracing said indicia and an observation of said hand as a mirrored image for perceptual guidance of said hand in tracing said indicia as seen upon said mirrored surface.
Claim 3
Dependent Claim
79 words
The structure set forth in claim 1, including an upwardly inclined frame member supporting said transparent panel member, an upwardly inclined frame member supporting said mirrored panel member, means hingedly connecting said frame members adjacent their upper end portions, means holding said frame members in spaced relation adjacent their bottom portions, said first mentioned frame member having a pair of oppositely facing slots rearwardly of said transparent panel member, and said transparent sheet member being disposed within said slots.
Claim 4
Dependent Claim
38 words
The structure set forth in claim 1, including a second panel member having a mirrored surface, means positioning said second panel member to reflect said indicia in cooperation with said first mentioned panel member having a mirrored surface.
Claim 5
Dependent Claim
56 words
The structure set forth in claim 1, including a second panel member having a mirrored surface, said panel members being arranged in an upright relationship and positioned to have adjacent end portions, means hingedly connecting said adjacent end portions of said panel members, and said panel members having mirrored surfaces being arranged to reflect said indicia.
Claim 6
Dependent Claim
118 words
A perceptual educational tracing apparatus, having in combination a first and second substantially rectangular frame members in plan in opposed upright angled relationship to one another, means hingedly connecting said frame members at their adjacent upper portions, means holding the lower portions of said frame members in opposed relation, a panel member substantially overlying one of said frame members, said panel member being transparent, a transparent sheet member bearing indicia thereon, means removably holding said transparent sheet member to underlay said transparent panel member, a panel member substantially overlying said other of said frame members, and said last mentioned panel member having a mirrored surface facing said first mentioned panel member and reflecting an image of said indicia.
