Claim:
A battery chamber structure for an electronic apparatus, comprising: a casing having an opening, through which a battery is inserted into a battery chamber; and a battery chamber lid detachably attached to said opening to close said battery chamber, wherein said battery includes a first connector which connects to a second connector of said electronic apparatus, said second connector being provided inside said opening, said first connector connecting to a side of said second connector which faces said opening, a portion of said battery chamber lid adjacent to said first connector, when said first connector is connected to said second connector, is shaped to mechanically prevent said first connector from disengaging from said second connector when said battery chamber lid is attached to said opening, and said portion of said battery chamber lid comprises an engager which is engageable with a portion of said casing to fix said battery chamber lid to said casing, said engager facing said second connector when said battery chamber lid attaches to said opening, a gap being formed between said engager and a back surface of the first connector which faces said battery chamber lid in a disengaging direction in which said first connector disengages from said second connector, when said battery chamber lid attaches to said opening, said gap being smaller than a minimum clearance behind said back surface of said first connector which is necessary for disengaging said first connector from said second connector in said disengaging direction, wherein said engager has one of a substantially U-shaped cross section and a substantially V-shaped cross section, and comprises a crest which abuts the back surface of the first connector to prevent disengagement.
