Abstract
Abstract An electronic apparatus has a first and a second engaging portion. After the first engaging portion has mated with a hook portion included in a battery pack, the battery pack is pressed against the casing of the apparatus. As a result, a lock lever extending from the battery pack bends in a first direction and mates with the second locking portion. A wall portion is formed in the battery pack outboard of the lock lever and provided with adequate strength and elasticity. The wall portion protects the lock lever from damage when an excessive force, tending to bend the lock lever in a second direction opposite to the first direction, acts on the lever.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
171 words
A structure for removably holding on a casing of an electronic apparatus a battery pack which accommodates batteries for feeding power to said electronic apparatus, said structure comprising: a first and a second flat engaging portion extending from said casing in opposite directions for locking said battery pack in a longitudinal direction; a hook portion provided on one end of said battery pack in the longitudinal direction for mating with said first engaging portion; an elastic lock lever extending from the other end of said battery pack with respect to the longitudinal direction for mating with said second engaging portion due to elasticity when said battery pack is pressed against said casing after said first engaging portion and said hook portion have mated with each other, thereby locking said battery pack to said casing; and a wall portion extending from said battery pack outboard of said lock lever for protecting said lock lever from damage when an excessive force, tending to bend said lock lever outward, acts on said lock lever.
Claim 2
Dependent Claim
171 words
A structure for removably holding on a casing of an electronic apparatus a battery pack which accommodates batteries for feeding power to said electronic apparatus, said structure comprising: a first and a second flat engaging portion extending from said casing in opposite directions for locking said battery pack in a longitudinal direction; a hook portion provided on one end of said battery pack in the longitudinal direction for mating with said first engaging portion; an elastic lock lever extending from the other end of said battery pack with respect to the longitudinal direction for mating with said second engaging portion due to elasticity when said battery pack is pressed against said casing after said first engaging portion and said hook portion have mated with each other, thereby locking said battery pack to said casing; and a wall portion extending from said battery pack outboard of said lock lever for protecting said lock lever from damage when an excessive force, tending to bend said lock lever outward, acts on said lock lever.
Claim 3
Dependent Claim
39 words
A structure as claimed in claim 1, wherein said wall portion has strength and elasticity which prevent said lock lever from bending outward against the excessive force, while insuring engagement of said lock lever with said second engaging portion.
Claim 4
Dependent Claim
103 words
A structure for removably holding on a casing of an electronic apparatus a battery pack which accommodates batteries for feeding power to said electronic apparatus, said structure comprising: an accommodating portion provided in said casing for accommodating said battery pack; a first and a second engaging portion formed in said accommodating portion; a hook portion formed in said battery pack for mating with said first engaging portion; a swayable lock lever extending from said battery pack and terminating at a lug engageable with said second engaging portion; and member provided in said battery pack for limiting a swaying motion of said lock lever.
Claim 5
Dependent Claim
103 words
A structure for removably holding on a casing of an electronic apparatus a battery pack which accommodates batteries for feeding power to said electronic apparatus, said structure comprising: an accommodating portion provided in said casing for accommodating said battery pack; a first and a second engaging portion formed in said accommodating portion; a hook portion formed in said battery pack for mating with said first engaging portion; a swayable lock lever extending from said battery pack and terminating at a lug engageable with said second engaging portion; and member provided in said battery pack for limiting a swaying motion of said lock lever.
Claim 6
Dependent Claim
19 words
A structure as claimed in claim 3, wherein said lock lever comprises an elastic member made of a plastic.
