Description

DETAILED DESCRIPTION OF THE INVENTION The present invention can be used as a digital wristwatch storage device that secures a storage space for a digital wristwatch that has been removed from the wrist, and can also be used as a signal source for displaying the time of the stored digital wristwatch. The present invention relates to a completely novel digital clock that uses its own digital time display to digitally display the same time as that currently displayed by the digital wristwatch.

The present invention will be described below with reference to a first embodiment shown in FIGS. 1 and 2, a second embodiment shown in FIGS. 3 and 4, and a third embodiment shown in FIGS. 5 and 6. Two embodiments will be described in detail.

First, a first embodiment will be described. As shown in FIG. 1, a digital time display 3 is integrally provided on one side of a container body 2 provided with an upper lid 1. As shown in FIG.

A wristwatch storage recess 4 having a shape 0 adapted to the outer contour of the digital wristwatch is provided below the top 1 and inside the container 2 to store and place the digital wristwatch.

A power switch 5 is provided on the top cover 1. Then, by opening the upper case 1 and storing the digital watch in the watch storage recess 4, the digital time display body 3 will match the time currently displayed by the stored digital watch. The same time is displayed digitally.

That is, as shown in FIG.
A sensor group 7 is arranged to detect whether each display segment provided on the time display surface 6a of the digital wristwatch 6 is in a display state. 8, each display segment 9 of the digital time display 3 is operated.

Next, the second embodiment has a configuration in which an alarm mechanism is added to that of the first embodiment described above.

That is, as shown in Fig. 3, a group of keys 10 such as numeric keys are arranged on the top cover 1, and these collectively constitute a means for setting the alarm time, and when these keys are pressed, the alarm time is set. The alarm time output is stored in the storage circuit 11 as shown in FIG. And this memory circuit 1
1 and the output increased by the intensifier 8 of the sensor group 7 are compared in the alarm time determination circuit 12, and the time display of the digital wristwatch detected by the sensor group 7 is compared with the set alarm time. When they match, the alarm time determination circuit 12
The alarm device 13 is activated by the output.
Next, the third embodiment has a configuration in which a timer mechanism is added to that of the first embodiment described above.

That is, as shown in FIG. 5, a group of keys 14 such as numeric keys constituting a means for setting the timer time are arranged on the top of the upper part 1, and the timer time output generated by pressing these keys is The data is stored in the storage circuit 15 as shown in the figure. The output of this memory circuit 15 and the output multiplied by the multiplier 8 of the sensor group 7 are compared in the timer time determination circuit 16, and the time display of the digital wristwatch sensed by the sensor group 7 is set. When the set timer time coincides with the set timer time, the output of the timer time judgment circuit 16 is used to switch circuit 1 such as a relay.
7 is configured to switch. This switch circuit 17 has a connector 1 for connecting external electrical equipment.
8 are connected. In addition, in any case of the first to third embodiments described above, if the entire surface of the container body 2 (including the top lid 1) and the digital time display body 3 are magnetically shielded by a known method, television reception is possible. Even if it is placed near devices that generate magnetic fields, such as machines or radio receivers, the rate will not go awry. As described above, the digital clock of the present invention can be used as a storage container for storing a digital wristwatch that has been removed from the wrist, and can also display the digital time using the time display of the digital wristwatch as a signal source for time display. It is economical because it does not require a dedicated signal source, and is innovative as a digital clock.

Furthermore, if an alarm mechanism is added as in the invention set forth in claim 3, or a timer mechanism is added as in the invention set forth in claim 4, the utility value thereof will further increase.

Furthermore, if magnetic shielding is provided as in the embodiment of claim 2, the rate will not go out of order even in a place where a magnetic field is generated.
