An electronic apparatus comprising: a flexible display wound at an edge of the electronic apparatus and configured to be exposed on a front side and a rear side, wherein the edge is located between the front side and the rear side, and the size of the portion of the flexible display that is exposed on the front side is changeable, wherein the rear side is located opposite to the front side; a first sensor; and a motor for controlling the size of said exposed portion of the flexible display on said front side in response to a signal from said first sensor; characterized by: the first sensor being a pressure sensor disposed at a specific position at the rear side of the electronic apparatus in the base part of the fixed part and configured to sense a pressure applied at said specific position, the apparatus comprising a fixed part and a variable part, wherein the fixed part and the variable part are slideably engaged and relatively moveable in a sliding manner such that when the variable part, while remaining slideably engaged with the fixed part, slidably moves away from the fixed part, the exposed flexible display portion on the front side increases in size in the moving direction and when the variable part slidably moves towards the fixed part, the exposed flexible display portion on the front side decreases in size in the moving direction, and a controller configured to control the motor to increase said size of the portion of the flexible display exposed on the front side by moving away said variable part from said fixed part when the pressure detected by the first sensor is greater than a predetermined value. a flexible display wound at an edge of the electronic apparatus and configured to be exposed on a front side and a rear side, wherein the edge is located between the front side and the rear side, and the size of the portion of the flexible display that is exposed on the front side is changeable, wherein the rear side is located opposite to the front side; a first sensor; and a motor for controlling the size of said exposed portion of the flexible display on said front side in response to a signal from said first sensor; characterized by: the first sensor being a pressure sensor disposed at a specific position at the rear side of the electronic apparatus in the base part of the fixed part and configured to sense a pressure applied at said specific position, the apparatus comprising a fixed part and a variable part, wherein the fixed part and the variable part are slideably engaged and relatively moveable in a sliding manner such that when the variable part, while remaining slideably engaged with the fixed part, slidably moves away from the fixed part, the exposed flexible display portion on the front side increases in size in the moving direction and when the variable part slidably moves towards the fixed part, the exposed flexible display portion on the front side decreases in size in the moving direction, and a controller configured to control the motor to increase said size of the portion of the flexible display exposed on the front side by moving away said variable part from said fixed part when the pressure detected by the first sensor is greater than a predetermined value. the first sensor being a pressure sensor disposed at a specific position at the rear side of the electronic apparatus in the base part of the fixed part and configured to sense a pressure applied at said specific position, the apparatus comprising a fixed part and a variable part, wherein the fixed part and the variable part are slideably engaged and relatively moveable in a sliding manner such that when the variable part, while remaining slideably engaged with the fixed part, slidably moves away from the fixed part, the exposed flexible display portion on the front side increases in size in the moving direction and when the variable part slidably moves towards the fixed part, the exposed flexible display portion on the front side decreases in size in the moving direction, and a controller configured to control the motor to increase said size of the portion of the flexible display exposed on the front side by moving away said variable part from said fixed part when the pressure detected by the first sensor is greater than a predetermined value.
