Abstract
Abstract A mark indicator comprises a transparent substrate; a recessed portion formed on a rear face of the transparent substrate and having a tapered shape widened on an open side thereof and having the shape of an indicating medium; and an indicating layer of the indicating medium disposed within the recessed portion. An alternative embodiment comprises an indicating substrate composed of a transparent material; and an indicating layer member disposed on a rear face of the indicating substrate and including an indicating layer having the shape of an indicating medium and substantially a trapezoidal shape in cross section, and a transparent layer disposed in a portion of the indicating layer member except for the indicating layer and substantially having the same thickness as that of the indicating layer. A method for manufacturing a mark indicator comprises the steps of forming a projecting portion in a molding die; setting a film and an indicating layer within the molding die; and flowing a transparent material into the molding die. An alternative method for manufacturing a mark indicator comprises the steps of setting, within a molding die, a film and an indicating layer member which includes an indicating layer and a transparent layer; and flowing a transparent material into the molding die.

Claim 2
Dependent Claim
55 words
A mark indicator comprising: a transparent substrate; a recessed portion formed on a rear face of the transparent substrate and having a tapered shape widened on an open side thereof and having the shape of an indicia; and an indicating layer comprised of a solid transfer of an indicating medium disposed within the recessed portion.
Claim 3
Dependent Claim
16 words
A mark indicator as claimed in claim 1, wherein the indicating medium comprises characters and numerals.
Claim 4
Dependent Claim
25 words
A mark indicator as claimed in claim 1, wherein the indicating layer has a tapered portion and the tapered portion has a predetermined inclination angle.
Claim 5
Dependent Claim
55 words
A mark indicator as claimed in claim 3, wherein said indicating medium is in the form of an indicating layer having a trapezoidal shape in cross section, and a transparent layer disposed in a portion of the indicating medium about the indicating layer and substantially having the same thickness as that of the indicating layer.
Claim 6
Dependent Claim
16 words
A mark indicator as claimed in claim 4, wherein the indicating medium comprises characters and numerals.
Claim 7
Dependent Claim
22 words
A mark indicator as claimed in claim 4, wherein the indicating medium is transferred by pressure and heat during molding transparent material.
Claim 8
Dependent Claim
156 words
A mark indicator comprising: a transparent substrate; a recessed portion formed on a rear face of the transparent substrate and having a tapered shape widened on an open side thereof and having the shape of an indicia; a solid indicating layer of an indicating medium disposed within the recessed portion and having a tapered portion; a first colored layer disposed on the rear side of the transparent substrate and a second colored layer disposed on the first colored layer; wherein the indicating medium has the shape of a character or numeral; wherein the indicating layer is formed by transfer of a solid layer of the indicating medium within the recessed portion; wherein the first colored layer is disposed by transfer on the rear side of the transparent substrate; wherein the second colored layer is disposed by transfer on the first colored layer; and wherein the tapered portion has a predetermined inclination angle of at least 10°.
Claim 9
Dependent Claim
156 words
A mark indicator comprising: a transparent substrate; a recessed portion formed on a rear face of the transparent substrate and having a tapered shape widened on an open side thereof and having the shape of an indicia; a solid indicating layer of an indicating medium disposed within the recessed portion and having a tapered portion; a first colored layer disposed on the rear side of the transparent substrate and a second colored layer disposed on the first colored layer; wherein the indicating medium has the shape of a character or numeral; wherein the indicating layer is formed by transfer of a solid layer of the indicating medium within the recessed portion; wherein the first colored layer is disposed by transfer on the rear side of the transparent substrate; wherein the second colored layer is disposed by transfer on the first colored layer; and wherein the tapered portion has a predetermined inclination angle of at least 10°.
Claim 10
Dependent Claim
41 words
A mark indicator as claimed in claim 3, further comprising a first colored layer disposed on the rear side of the transparent substrate, and a second colored layer disposed on the first colored layer on the side opposite said transparent substrate.
Claim 11
Dependent Claim
29 words
A mark indicator as claimed in claim 8, wherein said predetermined angle is at least 10°, whereby a stereo effect is provided for said shape of the indicating medium.
Claim 12
Dependent Claim
134 words
A mark indicator comprising: an indicating substrate comprising a transparent material; at least one indicating medium disposed on a rear face of the indicating substrate, said indicating medium being formed of an indicating layer of solid material shaped into the form of an indicating character and having a color discernible through said indicating substrate; means for providing a stereo effect to said indicating medium, said means comprising said indicating character having a cross-sectional shape that tapers outwardly transversely of said indicating substrate in the direction from front to back of said indicating substrate, wherein said taper has an angle of at least 10°; a first colored layer disposed on the rear side of the transparent substrate; and a second colored layer disposed on the first colored layer on the side opposite said transparent substrate.
Claim 13
Dependent Claim
134 words
A mark indicator comprising: an indicating substrate comprising a transparent material; at least one indicating medium disposed on a rear face of the indicating substrate, said indicating medium being formed of an indicating layer of solid material shaped into the form of an indicating character and having a color discernible through said indicating substrate; means for providing a stereo effect to said indicating medium, said means comprising said indicating character having a cross-sectional shape that tapers outwardly transversely of said indicating substrate in the direction from front to back of said indicating substrate, wherein said taper has an angle of at least 10°; a first colored layer disposed on the rear side of the transparent substrate; and a second colored layer disposed on the first colored layer on the side opposite said transparent substrate.
