Abstract

Abstract An electronic apparatus such as a compact computer, a compact information processor, and a compact word processor comprises a pivotal cover carrying a display. The pivotal cover is closed on a keyboard of the electronic apparatus. The display is secured on a surface of the pivotal cover facing a surface of the keyboard during the closing. The pivotal cover is opened to uprise the display with an inclination angle to operate the display. The inclination angle of the pivotal cover can be controlled with a help of gears and dampers provided in two legs of the pivotal cover.

Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 330 words
An electronic apparatus comprising: a body having a front portion, a rear portion, an upper face and sidewalls extending from said front portion to said rear portion for defining a housing therebetween, a socket is provided in one sidewall and is positioned adjacent to said rear portion; a keyboard located on the upper face of said body and being positioned adjacent to said front portion of said body; a cover, having an inner face and leg members, said leg members being pivotably mounted on said sidewalls of said body for covering and protecting said keyboard when said cover is in a closed position; a display located on the inner face of said cover; a paper feed device having a retractable rotatable paper feed handle positioned within the socket of said body during a nonoperational mode and extendable from said socket and manually manipulated for paper feeding during an operational mode; said paper feed device comprises: a paper feeding roller having two ends and a roller axis; a rod, having two ends, colinear with said paper feeding roller axis with one end operatively connected to and extending from one end of said paper feeding roller; a boss operatively attached to the other end of said rod, said boss including a pin extending from said boss and substantially perpendicular to the feeding roller axis, said boss including a hole substantially perpendicular to said feeding roller axis in which a spring and a ball are positioned with said spring biasing said ball from said hole in said boss; said retractable rotatable paper feed handle including a hollow shaft in which said boss is slidably received, the hollow shaft including a groove into which said pin of said boss is received constituting stops for said pin, the hollow shaft including two holes into which alternatively said ball can be biased constituting a click mechanism for substantially retaining said retractable rotatable paper feed handle in either a retracted nonoperational mode or an extended operational mode.
Claim 2
Dependent Claim 330 words
An electronic apparatus comprising: a body having a front portion, a rear portion, an upper face and sidewalls extending from said front portion to said rear portion for defining a housing therebetween, a socket is provided in one sidewall and is positioned adjacent to said rear portion; a keyboard located on the upper face of said body and being positioned adjacent to said front portion of said body; a cover, having an inner face and leg members, said leg members being pivotably mounted on said sidewalls of said body for covering and protecting said keyboard when said cover is in a closed position; a display located on the inner face of said cover; a paper feed device having a retractable rotatable paper feed handle positioned within the socket of said body during a nonoperational mode and extendable from said socket and manually manipulated for paper feeding during an operational mode; said paper feed device comprises: a paper feeding roller having two ends and a roller axis; a rod, having two ends, colinear with said paper feeding roller axis with one end operatively connected to and extending from one end of said paper feeding roller; a boss operatively attached to the other end of said rod, said boss including a pin extending from said boss and substantially perpendicular to the feeding roller axis, said boss including a hole substantially perpendicular to said feeding roller axis in which a spring and a ball are positioned with said spring biasing said ball from said hole in said boss; said retractable rotatable paper feed handle including a hollow shaft in which said boss is slidably received, the hollow shaft including a groove into which said pin of said boss is received constituting stops for said pin, the hollow shaft including two holes into which alternatively said ball can be biased constituting a click mechanism for substantially retaining said retractable rotatable paper feed handle in either a retracted nonoperational mode or an extended operational mode.
