Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
122 words
1 . A computer comprising: a base having a key input section; a built-in unit provided at a side portion of the base, the built-in unit being capable of sliding between an accommodation position where the built-in unit is accommodated inside an accommodation space inside the base and a protruding position where the built-in unit protrudes from the inside of the base, the built-in unit including an input section having a numerical keypad; and switching means, disposed between the base and the built-in unit, for performing a switching operation so that, when the built-in unit is at the protruding position, a numerical keypad operation signal from any one of the numerical keypad keys can be applied to a circuit in the base.
Claim 2
Dependent Claim
122 words
1 . A computer comprising: a base having a key input section; a built-in unit provided at a side portion of the base, the built-in unit being capable of sliding between an accommodation position where the built-in unit is accommodated inside an accommodation space inside the base and a protruding position where the built-in unit protrudes from the inside of the base, the built-in unit including an input section having a numerical keypad; and switching means, disposed between the base and the built-in unit, for performing a switching operation so that, when the built-in unit is at the protruding position, a numerical keypad operation signal from any one of the numerical keypad keys can be applied to a circuit in the base.
Claim 3
Dependent Claim
28 words
2 . A computer according to claim 1 , wherein the key input section on the base does not have an input section exclusively for the numerical keypad.
Claim 4
Dependent Claim
