Electronic apparatus, card-type electronic component used with the electronic apparatus, and electronic system with expanding apparatus for expanding function of electronic apparatus

Claim 2

An expanding apparatus for expanding functions of an electronic apparatus comprising: a main body having a bearing section for bearing the electronic apparatus and expanding means for expanding the functions of the electronic apparatus; a plug-in type connector provided on the main body and electrically connected to the expanding means, for removably receiving a matching plug-in type connector of the electronic apparatus loaded on the bearing section; and a support assembly for supporting the connector of the expanding apparatus to be movable between a stand-by position and a pushed in position in a predetermined direction for engaging and disengaging from the connector of the electronic apparatus, the support assembly including a support member to which the connector of the expanding apparatus is attached, the support member having a plurality of guide holes, and a plurality of guide members extending from the main body in the predetermined direction through the respective guide holes, each of the guide members having an extended end and a stopper provided on the extended end, for abutting the support member in the stand-by position to limit the movement of the connector, the extended end of each of the guide members having a diameter substantially equal to the diameter of the guide holes and each of the guide members being tapered off toward the main body.

Claim 3

An expanding apparatus according to claim 1, wherein said support assembly includes urging means fixed to the main body for urging the support member toward the stand-by position.

Claim 4

An expanding apparatus according to claim 1, wherein said support member includes a plate portion extending in a direction substantially perpendicular to the predetermined direction, said plate portion having guide holes.

Claim 5

Am expanding apparatus according to claim 3, wherein said main body includes a support frame facing the plate portion and wherein each of said guide members has a base end fixed to the support frame.

Claim 6

An expanding apparatus according to claim 4, wherein said support assembly has urging means arranged between the plate portion and the support frame for urging the support member toward the standby position.

Claim 7

An expanding apparatus for expanding functions of an electronic apparatus, comprising: a main body having a bearing section for bearing the electronic apparatus and expanding means for expanding the functions of the electronic apparatus; a plug-in type connector provided on the main body and electrically connected to the expanding means, for removably receiving a matching plug-in type connector of the electronic apparatus loaded on the bearing section; and a support assembly for supporting the connector of the expanding apparatus to allow the connector of the expanding apparatus to move in a direction for engaging and disengaging from the connector of the electronic apparatus wherein said support assembly comprises a connector holder holding the connector of the expanding apparatus, a support member for supporting the connector holder to be movable in the direction of engagement and disengagement between a stand-by position and a pushed-in position, and urging means fixed to the main body, for urging the connector holder toward the stand-by position and wherein said support member is provided with a plurality of guide holes, and said support assembly comprises a plurality of guide sleeves extending from the main body in the direction of engagement and disengagement and extending through the respective guide holes, each of said guide sleeves having a base portion rigidly fixed to the main body, an end portion extending from the main body, and a stopper provided on the end portion, for abutting the connector holder in its stand-by position to limit the movement of the connector holder, each of said guide sleeves being tapered from the end portion to the base section, the end portion having a diameter substantially equal to the diameter of the guide holes, and the base portion having a diameter smaller than the diameter of the guide holes.

Claim 8

An expanding apparatus for expanding functions of an electronic apparatus, comprising: a main body having a bearing section for bearing the electronic apparatus and expanding means for expanding the functions of the electronic apparatus; a plug-in type connector provided on the main body and electrically connected to the expanding means, for removably receiving a matching plug-in type connector of the electronic apparatus loaded on the bearing section; and a support assembly for supporting the connector of the expanding apparatus to allow the connector of the expanding apparatus to move in a direction for engaging and disengaging from the connector of the electronic apparatus wherein said support assembly comprises a connector holder holding the connector of the expanding apparatus, a support member for supporting the connector holder to be movable in the direction of engagement and disengagement between a stand-by position and a pushed-in position, and urging means fixed to the main body, for urging the connector holder toward the stand-by position and wherein said support member is provided with a plurality of guide holes, and said support assembly comprises a plurality of guide sleeves extending from the main body in the direction of engagement and disengagement and extending through the respective guide holes, each of said guide sleeves having a base portion rigidly fixed to the main body, an end portion extending from the main body, and a stopper provided on the end portion, for abutting the connector holder in its stand-by position to limit the movement of the connector holder, each of said guide sleeves being tapered from the end portion to the base section, the end portion having a diameter substantially equal to the diameter of the guide holes, and the base portion having a diameter smaller than the diameter of the guide holes.
