Abstract

Abstract A toy computer is presented which contains a keyboard providing for input and operation with two numbers or characters, simulates the internal computation like a real computer by a series of flashing lights, and produces the answer at one location on a panel. The two characters are input by depressing two keys, but the answer is not produced until a compute knob is turned, and a short cycle of flashing lights has occurred.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 143 words
A toy computer for performing a mathematical operation with two characters, said computer comprising a housing, an answer window on said housing, an answer member movably mounted in said housing, a keyboard comprising first and second groups of keys movably mounted on said housing and representing, respectively, first and second sets of characters, said answer member having a surface bearing thereon, in a fixed orderly array, representations of all solutions that can result from performing said mathematical operation with any two characters selected one from each said set, means connected to said answer member and to each said key for moving said answer member in response to movement of said keys whereby sequential actuation of two keys, one of each said group, produces sequential movements of said answer member to align with said answer window the solution representation corresponding to said two keys.
Claim 2
Dependent Claim 143 words
A toy computer for performing a mathematical operation with two characters, said computer comprising a housing, an answer window on said housing, an answer member movably mounted in said housing, a keyboard comprising first and second groups of keys movably mounted on said housing and representing, respectively, first and second sets of characters, said answer member having a surface bearing thereon, in a fixed orderly array, representations of all solutions that can result from performing said mathematical operation with any two characters selected one from each said set, means connected to said answer member and to each said key for moving said answer member in response to movement of said keys whereby sequential actuation of two keys, one of each said group, produces sequential movements of said answer member to align with said answer window the solution representation corresponding to said two keys.
Claim 3
Dependent Claim 189 words
A toy computer as in claim 1 for simulating a real computer by means of flashing lights, said computer comprising a compute knob on said housing, a row of windows on said housing, a torsion spring wound light oscillating cylinder mounted in said housing behind said row of windows and operatively connected to said compute knob, a battery powered bulb mounted in said housing behind said light oscillating cylinder, a rotatable cam mounted in said housing, an answer window cover slidably mounted over said answer window in said housing, said cylinder having off centered longitudinally spaced holes through it perpendicular to its axis and angularly spaced around the cylinder, said holes being in line one at a time with the row of windows on computer housing upon respective orientation of cylinder, whereby actuation of said compute knob allows rotation of said light oscillating cylinder thereby producing flashes of light in sequence at each window as the cylinder rotates through one revolution, means operatively connecting said cylinder to said cam for rotating said cam for effecting the release of said answer window cover from in front of said answer window.
Claim 4
Dependent Claim 45 words
A toy computer as claimed in claim 1, including a series of windows in said housing and a series of small bulbs located at said windows and means including a rotating contact for causing said bulbs to light at random thereby simulating a real computer.
