1. An assembly for measuring bio-information, the assembly comprising:
a finger contact interface configured to be actuated based on a contact force applied by a finger of a user to the finger contact interface, the finger contact interface comprising an interface body configured to contact the finger of the user on a first side of the interface body;
a bio-sensor configured to measure the bio-information of the user based on the finger being in contact with the finger contact interface;
a force sensor configured to measure the contact force of the finger applied to the finger contact interface; and
a support configured to guide movement of the finger contact interface and support the force sensor against the finger contact interface,
wherein the force sensor is provided between an outer surface of the support and a second side of the interface body opposite the first side of the interface body,
wherein the bio-sensor comprises:
a light emitter external to the support and provided in the finger contact interface, the light emitter configured to emit light to a tissue of the finger in contact with the finger contact interface; and
a light receiver provided within the support and configured to receive light reflected from an irradiated tissue of the finger in contact with the finger contact interface, the irradiated tissue being irradiated from light emitted from the light emitter,
wherein the finger contact interface comprises a light path part that extends from the light emitter to the light receiver provided within the support, and
wherein the light path part comprises a first portion having a first width and that is external to the support, a second portion having a second width less than the first width and that is both external and internal to the support, and a third portion having a third width that is less than the second width and that is internal to the support.
