BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a clock device used for, for example, an alarm clock.

[0002]

2. Description of the Related Art Alarm clocks that output an alarm sound at a preset time, and wake up a sleeping user or the like, for example, have been widely used. For example, when an alarm sound is output from an alarm clock to a sleeping user, the user who wakes up with the alarm sound usually stops the alarm sound by pressing a silence stop button and simultaneously checks the current time. For this reason, this type of alarm clock is often placed in a position where the user can easily recognize the time at any time within the reach of the user.

[0003]

An alarm clock alarm switch is generally provided at the top of a clock device.
For example, the alarm sound can be easily stopped by reaching for the hand even if the user is on the floor. On the contrary,
Similarly, if the user tries to check the current time while lying on the floor, it is difficult to recognize the time and may recognize an incorrect time. A similar situation often occurs when the upper body cannot be raised for some reason.

[0004] In addition, for example, a wall clock may be slightly tilted in order to enhance the recognizability of the time and the like and to provide a decoration and a hobby, but in such a case, a conventional wall clock may be used. Then, the watch body must be tilted in some way and fixed to the wall in that state. Further, once the timepiece is fixed, it is extremely difficult to change its inclination angle.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned circumstances, and an object of the present invention is to be able to quickly and accurately recognize a display time irrespective of an installation state, with a simple structure. Another object of the present invention is to provide an interesting and interesting timepiece device in which the display angle of the dial can be set arbitrarily.

[0006]

In order to achieve the above object, a timepiece apparatus according to the present invention comprises a housing, a dial housed inside the housing and having a movement fixed to a back side thereof, A dial formed on the inner surface side of the housing and rotatably supporting the dial housed inside the housing in a direction along the inner surface of the housing, when the dial is rotated, the dial is moved to its rotational position.

A support portion rotatably supported in a direction along the inner surface of the housing, and a support portion for holding the dial at its rotational position when the dial rotates, and a rotation angle of the dial when the dial rotates And a pointer driving means for driving the pointer by the detected angle based on the angle detected by the angle detecting means, and a support formed on the inner surface of the housing includes a movement. Is fixed.

According to the timepiece device of the present invention, the dial supported by the supporting portion inside the housing is moved, for example, by moving a part of the dial exposed to the outside of the housing, so that the inside surface of the housing can be moved. Rotate in the direction along. When the movement of the exposed dial portion is stopped, the dial is held at the stop position by the above-described support. At this time, since the movement is fixed to the back side of the dial, the hands also move by the same rotation angle in accordance with the movement of the dial. As a result, even if the dial is rotated, the display time is always displayed at an accurate time.

Further, according to the timepiece device of the present invention, the dial supported inside the housing by the support portion is moved, for example, by moving a part of the dial exposed to the outside of the housing. It rotates in the direction along the inside of the body. When the movement of the exposed dial portion is stopped, the dial is held at the stop position by the above-described support.
At this time, since the movement is fixed at a predetermined position by the support portion, the movement does not rotate with the rotation of the dial.
In this case, since the position of the hands and the dial face are shifted from each other, when the rotation angle of the dial is detected by the angle detection means, the hands are moved by the hands only by the rotation angle of the dial based on the detection result. Move and always accurate time display is maintained.
