Patent ID: 7161800

Claim:
An electronic apparatus which is provided with a first unit and a second unit having a unit mounting section where the first unit is removably mounted, and in which an electronic circuit is incorporated, wherein: the first unit has an engagement recess in a portion to be attached to the unit mounting section, and the unit mounting section comprises: an elastic locking section which is pushed by the first unit as the first unit moves in a mounting direction and is elastically deformed by the pushing of the first unit causing the elastic locking section to bend in a direction of an upper surface of the second unit and away from the first unit, and enters the engagement recess upon completion of the mounting thereby to lock the first unit, and which receives a movement operation in an operating direction intersecting the mounting direction when the first unit is caused to leave the unit mounting section; and a run-on section onto which the elastic locking section runs when the elastic locking section has received a movement operation in the operating direction thereby to elastically deform the elastic locking member and release the engagement recess from the engagement of the elastic locking section.
