Abstract
A cellular phone includes a monitor portion 20 that is swingably mounted to a body. During a state from a point that the monitor portion 20 is fully closed to a point that the monitor portion 20 is opened through 45°, a shaft portion 106 of a damper member 110 prevents a shaft portion 112 from being interlocked therewith, and thus no damping force is exerted with respect to swinging of the monitor portion 20 during the above state. Thus, the monitor portion 20 can be opened speedily. When the monitor portion is opened through an angle in excess of 45°, the shaft portion 106 permits the shaft portion 112 of the damper member 110 to be interlocked therewith, and a damping force by the damper member 110 works on the shaft portion 112. Thus, the monitor portion 20 is opened slowly.
Claims26
An electronic device having a body and a lid comprising:
- a spindle portion including a mechanism for supporting and permitting the lid to be swung in a direction that said lid is opened from a closed position where the lid is closed by folding with respect to the body;
- a biasing mechanism provided on said spindle portion for biasing said lid in the direction that the lid is opened, thereby enabling the lid to perform an opening operation;
- and
- a damper mechanism for damping the opening operation of said lid, the damper mechanism being arranged to perform no damping operation during a state in which said lid, when opened, is in a range from a fully closed position to an angle less than or equal to a predetermined angle, the damper mechanism being also arranged to operate damping of the opening operation of said lid during a state in which said lid is opened through an angle in excess of the predetermined angle.
An opening/closing mechanism for an electronic device including a body and a lid, comprising:
- a spindle mechanism for supporting and permitting said lid to be swung in a direction that the lid is opened from a closed position that the lid is closed by folding with respect to the body;
- a biasing mechanism for biasing said lid in the direction that the lid is opened, thereby enabling the lid to perform an opening operation;
- and
- a damper mechanism for damping the opening operation of the lid, the damper mechanism being arranged to perform no damping operation during a state in which the lid, when opened, is in a range from a fully closed position to an angle less than or equal to a predetermined angle and to operate damping of the opening operation of the lid during a state in which the lid is opened through an angle in excess of the predetermined angle.
A folding type electronic device wherein there is provided a lid that is swingable with respect to a body, the electronic device characterized by comprising:
- a shaft portion about which the lid is swung;
- biasing means provided in said shaft portion for biasing said lid in an opening direction, thereby causing the lid to be opened;
- lock means for maintaining a closed position of said lid in a state in which an elastic force of said biasing means is accumulated;
- and
- damper means provided in said shaft portion, said damper means being arranged, after said lock means is released, to perform free running and release damping of a biasing force of said biasing means when said lid is positioned within a predetermined opening angle range, said damper means being also arranged to perform damping of a biasing force of said biasing means when said lid is positioned outside the predetermined opening angle range.
