Wrist-portable electronic apparatus and air chamber device |
摘要 |
A wrist-wearable electronic apparatus has a case and a band connected to the case for attaching the electronic apparatus to a wearer's wrist. A flexible expansion chamber is provided on the wrist side of the case or the band, and a pump communicates with the interior of the expansion chamber for supplying air thereto to inflate the expansion chamber so that it can be maintained in close contact with the wearer's wrist. The pump has a pair of push-in portions on opposed lateral sides of the case or band adjacent the wrist side thereof so that the wearer can apply sideways directed forces to actuate the push-in portions to supply air to the expansion chamber. A discharge valve communicates with the interior of the expansion chamber for discharging air therefrom. The pump may be rotatably mounted to enable the wearer to position the push-in portions at desired positions to facilitate actuation thereof by the wearer.
