Abstract
Abstract An input unit disposed between a mouse and a computer, the mouse being adapted to output a predetermined count number of pulse signals according to an amount of movement of the mouse. This output unit includes a count number converting device for gradually varying the count number of pulse signals outputted from the mouse and for outputting the varied count number to the computer. Preferably the count number converting device should be built in the mouse.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
154 words
An input unit disposed between a mouse and a computer, said mouse being adapted to output a predetermined count number of pulse signals according to an amount of movement of the mouse, said input unit comprising, count number converting means for varying the count number of pulse signals outputted from the mouse and for outputting the varied count number to the computer, said converting means including a latch circuit for converting the pulse signals from the mouse to a predetermined count number and for outputting the predetermined count number to the computer; a switch circuit for setting the count number of pulse signals to be outputted to the computer; and a count circuit for counting the pulse signals from the mouse based on a driving signal from said switch circuit and for providing a control signal to said latch circuit to very the count number of pulse signals to be outputted to the computer.
Claim 2
Dependent Claim
154 words
An input unit disposed between a mouse and a computer, said mouse being adapted to output a predetermined count number of pulse signals according to an amount of movement of the mouse, said input unit comprising, count number converting means for varying the count number of pulse signals outputted from the mouse and for outputting the varied count number to the computer, said converting means including a latch circuit for converting the pulse signals from the mouse to a predetermined count number and for outputting the predetermined count number to the computer; a switch circuit for setting the count number of pulse signals to be outputted to the computer; and a count circuit for counting the pulse signals from the mouse based on a driving signal from said switch circuit and for providing a control signal to said latch circuit to very the count number of pulse signals to be outputted to the computer.
Claim 3
Dependent Claim
58 words
An input unit according to claim 1, further including: a push-button switch disposed in said switch circuit for gradually setting the count number of pulse signals to be outputted to the computer; and an indicating means for indicating, based on the driving signal from said switch circuit, the step of the count number set by said push-button switch.
Claim 4
Dependent Claim
151 words
An input unit for inputting pulse signals to a computer, comprising: a mouse for outputting a predetermined count number of pulse signals according to an amount of movement of said mouse; and a count number converting means for varying the count number of pulse signals outputted from said mouse and for outputting the varied count number to the computer, said converting means including a latch circuit for converting the pulse signals from the mouse to a predetermined count number and for outputting the predetermined count number to the computer; a switch circuit for setting the count number of pulse signals to be outputted to the computer; and a counter circuit for counting the pulse signals from the mouse based on a driving signal from said switch circuit and for providing a control signal to said latch circuit to vary the count number of pulse signals to be outputted to the computer.
Claim 5
Dependent Claim
151 words
An input unit for inputting pulse signals to a computer, comprising: a mouse for outputting a predetermined count number of pulse signals according to an amount of movement of said mouse; and a count number converting means for varying the count number of pulse signals outputted from said mouse and for outputting the varied count number to the computer, said converting means including a latch circuit for converting the pulse signals from the mouse to a predetermined count number and for outputting the predetermined count number to the computer; a switch circuit for setting the count number of pulse signals to be outputted to the computer; and a counter circuit for counting the pulse signals from the mouse based on a driving signal from said switch circuit and for providing a control signal to said latch circuit to vary the count number of pulse signals to be outputted to the computer.
Claim 6
Dependent Claim
