Abstract
Abstract An electronic apparatus such as an electronic calculator has a detachable electric member such as an external memory card and, to avoid unfavorable effects such as destruction of memory at attaching or detaching of the electric member, the apparatus is provided with a switch which automatically turns off the power supply to the electric member when it is being attached to or detached from the apparatus.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
114 words
Electronic apparatus controlling mechanical and electrical connection to memory means, comprising: container means provided in the electronic apparatus for detachably holding the memory means; first movable means movable to a first position in which the memory means is electrically driven and to a second position in which the memory means is not electrically driven; second movable means mounted so as to be movable when said first movable means is moved from its first position to its second position; and third movable means mounted so as to be operable after movement of said second movable means; wherein the operation of said third movable means enables the memory means to be detached from said container means.
Claim 2
Dependent Claim
114 words
Electronic apparatus controlling mechanical and electrical connection to memory means, comprising: container means provided in the electronic apparatus for detachably holding the memory means; first movable means movable to a first position in which the memory means is electrically driven and to a second position in which the memory means is not electrically driven; second movable means mounted so as to be movable when said first movable means is moved from its first position to its second position; and third movable means mounted so as to be operable after movement of said second movable means; wherein the operation of said third movable means enables the memory means to be detached from said container means.
Claim 3
Dependent Claim
72 words
Electronic apparatus according to claim 1, wherein: said first movable means includes an electrical contact, a portion for limiting the movement of said second movable means and a portion for limiting the movement of said third movable means, said second movable means includes a portion for limiting the movement of said first movable means, and said third movable means includes a cover member for holding said memory means in said container means.
Claim 4
Dependent Claim
104 words
Electronic apparatus controlling mechanical connection and electrical control to memory means, comprising: container means provided in the electronic apparatus for containing the memory means; holding means movable among a first position, a second position and a third position for mechanically holding the memory means in said container means when said holding means is in the first and second positions thereof; and switch means for outputting an electrical signal to the memory means when said holding means is in the first position thereof, and for interrupting the electrical signal to the memory means when said holding means is in the second and third positions thereof.
Claim 5
Dependent Claim
104 words
Electronic apparatus controlling mechanical connection and electrical control to memory means, comprising: container means provided in the electronic apparatus for containing the memory means; holding means movable among a first position, a second position and a third position for mechanically holding the memory means in said container means when said holding means is in the first and second positions thereof; and switch means for outputting an electrical signal to the memory means when said holding means is in the first position thereof, and for interrupting the electrical signal to the memory means when said holding means is in the second and third positions thereof.
Claim 6
Dependent Claim
71 words
Electronic apparatus according to claim 3, further comprising a cover member stopped by said holding means for inhibiting removal of said memory means from said container means when said holding means is in the first and second positions thereof, and for permitting removal of the memory means from said container means when said holding means is in the third position thereof, wherein said cover member is released by said holding means.
