The present invention is not limited to the above embodiment, but can be variously modified. For example, the present invention can be similarly applied to a device other than a wristwatch such as an electronic organizer.

[0069]

As described above, according to the present invention,
The members involved in the original mechanism of the device are curved surfaces such as curves,
Since the film liquid crystal device is supported by the curved surface of this member, there is no need to process a member such as a housing which is not related to the function of the device into a curved surface, thereby facilitating the manufacture, and a member not related to the device such as the housing. Even if is omitted, since the film liquid crystal device can be supported in a curved shape, the structure can be simplified and the weight can be reduced.
