- the restraining means may be a component configured to solve the above problem, without an auxiliary device such as the sensor for determining whether the rotational cover is open or closed.
- the driving cam is rotated during the driving of the clothes treatment apparatus in a predetermined direction.
- the driving cam cannot be rotated any further by the restraining means such that an initial position of the rotational cover may be identified.
- the restraining means may be means enabling aroma to be supplied accurately according to a clothes treating course selected by the user, when a clothes treating course selected by the user does not require a aromatic fragrance supplying step after the abnormal condition is solved, or when a clothes treating course selected by the user is set to supply aroma to the clothes at a specific point after the clothes treatment apparatus is put into operation, for example, several minutes after a clothes treating course is implemented and several minutes before the driving of the clothes treatment apparatus is completed.
- control part (not shown) is required to control the motor and detailed description thereof will be provided in description of FIG. 13.
- FIG. 10 is an exploded perspective view partially illustrating that the driving cam 513 is separated from a rotational shaft 5121 of the motor 512 and FIG. 11 is a rear view of the driving cam 513.

- the rotational shaft 5121 of the motor 512 is inserted in a shaft inserting groove 5131 provided in a rear surface of the driving cam 513.
- the projection is insertedly received in the projection receiving groove 533.
- the projection 531 is an alternated long and short line in FIG. 11.
- the configuration of the projection and the projection receiving groove 533 used to determine the rotational angle of the driving cam 513 may be set variously.
- the shapes of the projection 531 and the projection receiving groove 533 may be determined to allow the driving cam to be rotated in a range of 180 degrees or less along a clockwise or counter-clockwise direction (along a main direction or a reverse direction). That is, when the shape of the projection receiving groove 533 is provided to receive the projection 531 from A position (0°) to B position (270°) as shown in FIG.
- the shape of the projection 531 may occupy a corresponding length of a circumference in a range of 0° to 90°, for example, a length of a circumference corresponding to A position to C position, to be rotatable inside the projection receiving groove 533 in a range of 180 degrees or less.
- an end of the projection 531 may contact with B position (0°) of the projection receiving groove 533 and the other end of the projection 531 is located at C position (90°) inside the projection receiving groove 533.
- the driving cam 513 tries to rotate in a clockwise direction, the projection 531 is interfered with by the projection receiving groove 533 and the rotation of the driving cam 513 is restrained.
- the driving cam 513 when the driving cam 513 is rotated to 180° along a counter-clockwise direction, the end of the projection 531 is located at D position inside the projection receiving groove 533 by the rotation of the projection receiving groove 533 and the other end of the projection 531 is located at B position inside the projection receiving groove 533.
- the projection receiving groove 533 interferes with the projection 531 and the driving cam 513 is prevented from rotating any further in the counter-clockwise direction. In other words, the driving cam 513 reaches the final position where the driving cam 513 cannot be rotated any further along the counter-clockwise direction.
- the rotational angle of the projection 531 may be restrained by the interference between the ends of the projection 531 and the projection receiving groove 533.
- the rotational angle of the driving cam 513 may be limited to 180° as shown in FIG. 11.
- the end of the projection receiving groove contacts with the end of the projection to prevent the driving cam from being rotated any further such that it may be determined that the driving cam reaches the final position.
- the driving cam is rotated 180° along a different direction (the other one of the main and reverse directions, that is, the clockwise and counter-clockwise directions)
- the other end of the projection receiving groove contacts with the other end of the projection and the driving cam is prevented from rotating any further such that the control part may determine that the driving cam is located at the initial position.
- the clothes treatment apparatus sets the state of the rotational cover being closed as the initial position of the driving cam described above.
- the rotational cover may be open according to the rotational angle of the driving cam. Because of that, the clothes treatment apparatus according to this embodiment may prevent the rotational cover from being open at a smaller angle than a preset opening angle or the aroma from being exposed to the accommodating space by incomplete closure of the rotational cover. Another effect that the rotational cover is kept open If the driving of the clothes treatment apparatus is stopped by an abnormal condition, with the rotational cover being open may be embodied by the restraining means and the control part (not shown).
- FIG. 12 is a conceptual diagram illustrating control for the driving cam 513 performed by the control part, if the rotational cover fails to reach the final position because the driving of the clothes treatment apparatus is stopped by the abnormal condition.
- FIG. 12 illustrates movement of the driving for explanation sake.
