BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a multifunction display timepiece having many functions and switching between data based on the functions and a display mode indicating the functions by hands.

[0002]

2. Description of the Related Art In a conventional multifunction display timepiece, time display and data display based on additional functions are displayed by separate display means. That is, the time is displayed by the hour hand and the minute hand, and data based on the additional function, for example, temperature,
The barometric pressure and the like are indicated by a dedicated guideline or the like.

[0003]

In the conventional multifunction display clock, as the number of functions increases, the number of pointers for display also increases. I had to enlarge the department. As described above, when the display unit is large, the exterior part of the timepiece must be enlarged, and there is a problem that the design and the installation place are limited.

[0004] The present invention has been made in view of the above problems,
It is an object of the present invention to provide a multifunction display timepiece that can prevent an increase in the size of a display unit due to multifunction by switching and displaying data based on each function and its mode with an hour hand and a minute hand.

[0005]

According to the present invention, there is provided a multifunction display timepiece, comprising: a display mode changeover switch for switching a display mode; reference signal generating means for outputting a reference signal; and counting a current time in response to the reference signal. Current time storage means for storing and storing data, additional function means for outputting data corresponding to the additional function, and switching and outputting data from the current time storage means and the additional function means in response to operation of the display mode switch. Switching conversion means for converting the data into the display position of the pointer in the set display range, target position storage means for storing the display position from the switching conversion means as the movement target position of the pointer, A display position storage means for storing a current display position; and a direction comparing the target position and the display position stored in the target position storage means and the display position storage means. If there is no match, the comparison and match detection means outputs a direction signal and a step signal to the display position storage means until they match, and responds to the direction signal and the step signal from the comparison and match detection means. And a motor for driving the hands in response to the drive signals. The mode conversion data is also converted to the display position by the switching conversion means. In this case, one of the hands displays the mode, and the other hand displays the data of the selected additional function.

The switching conversion means in the multifunction display timepiece of the present invention normally outputs the display positions of the hour hand and the minute hand based on the current time data in the time display mode. When the display mode switch is operated,
The switching conversion unit converts the display position into a display position in a set display range based on data from the additional function unit in accordance with the operation, and outputs the display position. The data in the target position storage means for storing the display position is compared with the data from the display position storage means for storing the current display position. It can be displayed in response to the switch. Further, by converting the display mode data into the display position and outputting the data by the switching conversion means, the data of the additional function selected by each of the hour hand and the minute hand and the mode of the display data can be displayed. Further, since the switching conversion means converts the input data to the display position, an arbitrary display range can be set, and a display device in which a large number of additional function data are divided into a predetermined display range can be provided. Further, the comparison / coincidence detection means determines the direction when the display position data changes and outputs a signal for driving the hands until the display position data coincides with the display position, so that the comparison / coincidence detection means can reciprocate within the divided display range. Is changed, the display is moved to the set display section.
