Abstract
Abstract The present invention relates to a thin battery-containing structure for an electronic apparatus which includes a lock pin provided on a flexible arm of a battery holder. The lock pin is guided to a predetermined position by a guide/lock groove in a case by pressing a battery holder inward for installing a battery in the battery container of the case. The lock pin is disengaged by the guide/lock groove when further inward force is applied. Upon removal of such force, the battery holder is pressed out of the battery container.

Claim 1
Independent Claim
300 words
A thin battery-containing structure for an electronic apparatus, comprising: a battery holder; a case having a battery-storing section including means for receiving said battery holder along an insertion direction; a first terminal plate located in said battery-storing section, said first terminal plate being in contact with one electrode of a thin battery having two electrodes when said battery holder with the thin battery received therein is housed in said battery-storing section inside of said case, said first terminal plate including at least one electrical contactor means for securing the thin battery therein; a second terminal plate located in said battery-storing section, said second terminal plate being in contact with the other electrode of the thin battery at least when said battery holder with the thin battery received therein is at a housed position in said battery-storing section inside of said case, said second terminal plate being placed perpendicularly to said first terminal plate and having resilient means for, when the battery holder is at its housed position, biasing the battery holder in a direction opposite to said insertion direction and, when the battery holder is released from said housed position, actuating motion of the battery holder in said opposite direction, a lock pin integral with said battery holder and supported by a flexible arm; and a guide/lock portion, located in said case, including means for guiding said lock pin, when said battery holder is pushed into said battery-storing section until said battery holder is engaged at a predetermined point to set said housed position, and means for releasing the engagement of said lock pin when said battery holder is pushed inward from the predetermined point to thereby enable movement of said battery holder by said resilient means in the opposite direction to withdraw said battery holder from said battery-storing section.
Claim 2
Dependent Claim
300 words
A thin battery-containing structure for an electronic apparatus, comprising: a battery holder; a case having a battery-storing section including means for receiving said battery holder along an insertion direction; a first terminal plate located in said battery-storing section, said first terminal plate being in contact with one electrode of a thin battery having two electrodes when said battery holder with the thin battery received therein is housed in said battery-storing section inside of said case, said first terminal plate including at least one electrical contactor means for securing the thin battery therein; a second terminal plate located in said battery-storing section, said second terminal plate being in contact with the other electrode of the thin battery at least when said battery holder with the thin battery received therein is at a housed position in said battery-storing section inside of said case, said second terminal plate being placed perpendicularly to said first terminal plate and having resilient means for, when the battery holder is at its housed position, biasing the battery holder in a direction opposite to said insertion direction and, when the battery holder is released from said housed position, actuating motion of the battery holder in said opposite direction, a lock pin integral with said battery holder and supported by a flexible arm; and a guide/lock portion, located in said case, including means for guiding said lock pin, when said battery holder is pushed into said battery-storing section until said battery holder is engaged at a predetermined point to set said housed position, and means for releasing the engagement of said lock pin when said battery holder is pushed inward from the predetermined point to thereby enable movement of said battery holder by said resilient means in the opposite direction to withdraw said battery holder from said battery-storing section.
