Reflective display including an integral motion sensing switch

A motion sensing switch, which recognizes motion of a reflection body moved at an upper side of a display part of a portable terminal and controls the portable terminal, comprising:

• a base which is disposed at an upper side of a main body of the portable terminal having the display part, which is outside the display part;
• a light receiving device which is disposed at the base;
• a plurality of light emitting devices which are disposed at the base so as to be symmetric with respect to the light receiving device;
• and
• a control device which operates the light emitting devices,
• wherein the light receiving device is disposed to be inclined toward the display part, and the light receiving device senses light emitted from the light emitting devices and reflected by the reflection body and transfers an operation signal to the control device, and the light emitting devices are disposed to be inclined in an opposite direction to the light receiving device, and the control device receives the operation signal and recognizes motion of the reflection body;
• and
• wherein the portable terminal is formed with a mounting groove in which the base is inserted, and
• the base comprises a first base which is inserted into the mounting groove and formed with a first inclined portion formed thereon to be inclined downward toward the display part;
• a second base which is installed at the first inclined portion and which has a through-hole formed at a center portion thereof and a second inclined portion formed around the through-hole to be inclined in an opposite direction to the through-hole;
• and a circuit board which is disposed between the first and second bases and on which the light receiving device is mounted, and
• the light receiving device is disposed at a lower side of the through-hole so as to sense the light emitted from the light emitting device through the through-hole, and
• the light emitting device is coupled to the second inclined portion and disposed to be inclined in an opposite direction to the light receiving device.
