Television game console and electronic control device for controlling the allowable playing time of the television game console

Claim 2

An electronic control device for controlling the allowable playing time of a television game console, said electronic control device comprising a timer control device for interfacing said television game console with a game cartridge read only memory unit, said timer control device including a means for generating a current time clock output, a means for receiving a presettable allowable playing time range input from said television game console, and a means for electrically connecting said game cartridge read only memory unit and said television game console only when said current time output is within said allowable playing time range input.

Claim 3

The electronic control device as claimed in claim 1, wherein said timer control device comprises: p1 a timer and alarm circuit means including a counter means for generating said current time clock output, and a means for generating a disable signal when said current time clock output is not within said allowable playing time range input; and a tri-state bus control logic means for receiving said disable signal, said tri-state bus control logic means connected between a first set of address bus lines and data bus lines connected to said game cartridge read only memory unit and a second set of address bus lines and data bus lines connected to said television game console, wherein said bus control logic means enters a high impedance state upon reception of said disable signal so as to break electrical connection between said game cartridge read only memory unit and said television game console.

Claim 4

The electronic control device as claimed in claim 2, further comprising a cell means for continuously supplying electric power to said timer and alarm circuit means.

Claim 5

A television game console comprising a central processing means and an electronic control device for controlling the allowable playing time of said television game console, said electronic control device including a timer control device for interfacing said central processing means with a game cartridge read only memory unit, said timer control device including means for generating a current time clock output, a means for receiving a presettable allowable playing time range input from said central processing means, and a means for electrically connecting said game cartridge read only memory unit and said central processing means only when said current time clock output is within said allowable playing time range input.

Claim 6

A television game console comprising a central processing means and an electronic control device for controlling the allowable playing time of said television game console, said electronic control device including a timer control device for interfacing said central processing means with a game cartridge read only memory unit, said timer control device including means for generating a current time clock output, a means for receiving a presettable allowable playing time range input from said central processing means, and a means for electrically connecting said game cartridge read only memory unit and said central processing means only when said current time clock output is within said allowable playing time range input.

Claim 7

The television game console as claimed in claim 4, wherein said timer control device comprises: a timer and alarm circuit means including a counter means for generating said current time clock output, and a means for generating a disable signal when said current time clock output is not within said allowable playing time range input; and a tri-state bus control logic means for receiving said disable signal, said tri-state bus control logic means connected between a first set of address bus lines and data bus lines connected to said game cartridge read only memory unit and a second set of address bus lines and data bus lines connected to said central processing means, wherein said bus control logic means enters a high impedance state upon reception of said disable signal so as to break electrical connection between said game cartridge read only memory unit and said central processing means.

Claim 8

The television game console as claimed in claim 5, wherein said central processing means comprises: range setting means for setting said allowable playing time range input wherein said range setting means receives a preset access code input and an input access code, and wherein the range setting means includes means for permitting the resetting of said allowable playing time range input only when said input access code matches said preset access code input.
