A portable telephone set of slide type comprising a main casing, a movable casing, the two casings being slidably coupled and capable of being locked to each other, and a lock releasing means for releasing the lock, wherein:
- the portable telephone set further comprises an illuminating means for illuminating the lock releasing means from the inner side, and further comprises a detecting means for detecting the advanced position of the main casing and the movable casing, a condition of the illuminating means being controlled according to whether the main casing and the movable casing have been retreated or advanced.
A portable telephone set comprising:
- a main casing,
- a movable casing,
- a slidable locking means for slidably locking the main and movable casings to each other,
- a lock release operator disposed on one side of the main or movable casing and operable for releasing the state of lock of the main and movable casings brought about by the slidable locking means, and
- an illuminating means for illuminating the lock releasing means from the inner side, wherein,
- the neighborhood of a part, in which the lock release operator of the main or movable casing is disposed, is at least partly made of a light-transmitting material, the illuminating means being “on”/“off” controlled at a call arrival call time or a main reception time and
- further comprises a detecting means for detecting the advanced position of the main casing and the movable casing, a condition of the illuminating means being controlled according to whether the main casing and the movable casing have been retreated or advanced.
