Claim 14:
15. An apparatus for estimating bio-information, the apparatus comprising:
an optical apparatus configured to:
induce congestion of a second portion of an object by pressing a first portion of the object; and
measure a bio-signal from the second portion; and

a processor configured to estimate the bio-information based on the bio-signal,
wherein the optical apparatus comprises:
an interface housing comprising:
a guide part defined by an interior space of the interface housing and configured to guide the object to a measurement position; and
a pressurizing part configured to induce the congestion of the second portion of the object by pressing the first portion when the object is disposed in the guide part; and

a measurer, comprising a light source and a detector, provided on an upper side of the guide part and configured to measure the bio-signal from the second portion when the object is at the measurement position,

wherein the pressurizing part comprises:
a plate configured to contact the first portion of the object; and
an elastic member that is connected to the plate and configured to deform as the first portion presses the plate,

wherein the interface housing further comprises a braking part configured to reduce movement of the plate caused by pressing of the first portion of the object, and
wherein the braking part comprises:
a first locking part connected to the plate and including a projection; and
a second locking part connected to the interface housing and having a groove configured to couple to the projection based on the first locking part being moved.
