Front and back panels are slidably attached to the elongate main body and configured to move in the longitudinal direction between an extended position and a retracted position. The panels include connectors configured to slide on rail members in a longitudinal direction. The connectors include a movable portion that is movable relative to a fixed portion, and which allows movement of the panel in a direction that is transverse to the longitudinal axis of the rail members. ## Claims ### Claim 1 An electronic cigarette device comprising: an elongate main body comprising a liquid store, at least one slideable panel connected to the elongate main body and movable in a longitudinal direction of the electronic cigarette device between an extended position and a retracted position, whereby the liquid store is exposed or more exposed when the at least one slideable panel is in the retracted position, and a first light source provided on the elongate main body that is configured to be rendered operable when the at least one slideable panel is in the retracted position, and that is configured to be rendered inoperable or invisible when the at least one slideable panel is in the extended position, wherein the at least one slideable panel comprises a translucent portion configured to be aligned with the first light source only when the at least one slideable panel is in the retracted position so that light from the first light source is visible through the translucent portion when the at least one slideable panel is in the retracted position, wherein the elongate main body further comprises a second light source, which is aligned with the translucent portion only when the at least one slideable panel is in the extended position so that light from the second light source is visible through the translucent portion when the at least one slideable panel is in the extended position. ### Claim 2 (depends on 1) The electronic cigarette device according to claim 1, wherein the first light source comprises a plurality of light emitting elements and each of the plurality of light emitting elements is aligned with a respective portion of the translucent portion only when the at least one slideable panel is in the retracted position. ### Claim 3 (depends on 2) The electronic cigarette device according to claim 2, wherein the respective translucent portions are divided from one another by optically opaque partitions. ### Claim 4 (depends on 1) The electronic cigarette device according to claim 1, wherein the first and second light sources are electrically connected to a printed circuit board. ### Claim 5 (depends on 1) The electronic cigarette device according to claim 1, further comprising at least one light diffuser configured to receive and diffuse light from the first light source. ### Claim 6 (depends on 1) The electronic cigarette device according to claim 1, wherein the at least one slideable panel comprises an actuator configured to activate a switch on the elongate main body to control a power supply between an operable state and an inoperable state when the at least one slideable panel is in the retracted and extended positions, respectively. ### Claim 7 (depends on 1) The electronic cigarette device according to claim 1, wherein the at least one slideable panel comprises a press-button that can activate a switch on the elongate main body to enable a production of inhalable aerosol. ### Claim 8 (depends on 7) The electronic cigarette device according to claim 7, wherein the press-button is movable from a first position towards a second position that is closer to the elongate main body, and wherein movement of the press-button from the first position towards the second position is inhibited when the at least one slideable panel is in the extended position. ### Claim 9 (depends on 8) The electronic cigarette device according to claim 8, wherein the elongate main body comprises at least one abutment, configured to inhibit movement of the press-button from the first position toward the second position. ### Claim 10 (depends on 9) The electronic cigarette device according to claim 9, wherein the abutment forms part of a light diffuser.
