Abstract
Abstract A portable radio telephone set comprises a telephone number generating apparatus and a telephone number transmitting apparatus which are preferably contained in a pencil shaped body (1). The telephone number generating means generates a telephone number signal, for instance, by sensing the motion of a ball (11) provided on a lower end of the body. The ball is moved to draw a telephone number on a surface of an article. The telephone number signal is modulated in the telephone number transmitting apparatus to be transmitted to air by an antenna (6) which is provided on an upper end of the body. <IMAGE>

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
66 words
A portable radio telephone set, comprising: means for generating pattern signals of letters indicative of a telephone number; a memory for storing patterns of letters; means for comparing said pattern signal and said stored pattern to generate a coincidence signal therebetween; and means for transmitting a telephone number signal to a station of a called party, said telephone number signal being provided by said coincidence signals.
Claim 2
Dependent Claim
113 words
A portable radio telephone set, according to claim 1, wherein: said generating means, said memory, said comparing means, and said transmitting means are contained in a main body having a pencil shape, said main body being held by a hand of an operator; said generating means includes a ball partly protruded out of a first end of said main body and rotating on a plane, means for detecting moving distances in first and second directions orthogonal to each other of said ball, and means for defining a pattern of a letter by said moving distances; and said transmitting means is connected to an antenna provided on a second end of said main body.
Claim 3
Dependent Claim
52 words
A portable radio telephone set, according to claim 2, wherein: said detecting means includes first and second photo-interruptors each having a light-passing and shielding gear which is rotated in a corresponding one of said first and second directions by said ball, said gear being positioned between said light emitting and receiving devices.
Claim 4
Dependent Claim
148 words
A portable radio telephone set, comprising: a ball rotating to be moved on a surface of an article by manipulation of an operator; first and second encoders for generating first and second signals of ball moving distances in first and second directions orthogonal to each other; means for generating pattern signals of letters in accordance with said first and second signals; a first memory for storing patterns of letters; a second memory having a first region for storing said pattern signals temporarily and a second region for storing said pattern signals transferred from said first region in non-volatile mode; means for comparing a pattern defined by said pattern signals with a pattern of said first memory to generate a coincidence signal; means for modulating a telephone number obtained from patterns determined by said coincidence signals; and means for transmitting said modulated telephone number to air by an antenna.
Claim 5
Dependent Claim
37 words
A portable radio telephone set, according to claim 4, wherein: said second memory stores a telephone number of a called party and a station name corresponding to said telephone number in the form of said pattern signals.
Claim 6
Dependent Claim
76 words
A portable radio telephone set, according to claim 4, wherein: said ball is partly protruded out of a first end of a pencil shaped main body; said first and second encoders, said generating means, said first memory, said second memory, said comparing means, said modulating means, and said transmitting means are contained in said pencil shaped main body; and said antenna is provided on a top of a second end of said pencil shaped main body.
Claim 7
Dependent Claim
109 words
A portable radio telephone set, comprising: means for scanning letters defined on a sheet material to generate pattern signals of said letters; a first memory for storing patterns of letters; a second memory having a first region for storing said pattern signals temporarily and a second region for storing said pattern signals transferred from said first region in non-volatile mode; means for comparing a pattern defined by said pattern signals with a pattern of said first memory to generate a coincidence signal; means for modulating a telephone number obtained from patterns determined by said coincidence signals; and means for transmitting said modulated telephone number to air by an antenna.
Claim 8
Dependent Claim
37 words
A portable radio telephone set, according to claim 7, wherein: said second memory stores a telephone number of a called party and a station name corresponding to said telephone number in the form of said pattern signals.
Claim 9
Dependent Claim
75 words
A portable radio telephone set, according to claim 7, wherein: said scanning means is provided at a first end of a pencil shaped main body; said first and second encoders, said generating means, said first memory, said second memory, said comparing means, said modulating means, and said transmitting means are contained in said pencil shaped main body; and said antenna is provided on a top of a second end of said pencil shaped main body.
Claim 10
Dependent Claim
46 words
A portable radio telephone set, according to claim 7, wherein: said scanning means, includes: a light source for emitting light to said sheet material; means for receiving light reflected from said sheet material; and means for generating said pattern signals by intensity of said received light.
