Abstract

PURPOSE:To listen to an alarm tone through easy operation all the time by generating the alaram tone when an external operation member moves from the 2nd to the 1st stable position. CONSTITUTION:Switching circuits SW1-SW3 are used in combination to perform display switching through a display switching circuit 4, make a time correction through a time counting circuit 3, set an alaram time through an alarm time storage circuit 10, and listen to the alaram tone through an alarm control circuit 12. The alarm control circuit 12 sends a signal from an alarm signal generating circuit 9 to a speaker driving circuit 13 to generate the alarm tone by the speaker 14. When the stem moves from the 2nd stage to the 1st stage, the switching circuit SW1 has transition from an H state to an L state. Its falling signal is utilized to transfer a listening signal to the alarm control circuit 12 through an operation control circuit 8, thereby generating the alarm tone.

Description

[Detailed description of the invention] The present invention relates to a γ2-man electronic watch.

The present invention is particularly useful for adjusting the time of an electronic clock by adjusting the alarm time, controlling an alarm device, or calling up an additional device. This invention relates to an electronic watch with an alarm that operates in a manner that includes the direction of rotation.

An object of the present invention is to provide an electronic watch with an alarm that allows you to listen to the alarm sound at any time with simple operations.

Another object of the present invention is to provide an electronic watch with an alarm that allows you to listen to the alarm sound without sacrificing the design or waterproof performance.

Another object of the present invention is to provide an electronic time side with an alarm that allows operation confirmation of the operating member to be confirmed by an alarm sound.

2. Description of the Related Art With the recent development of electronics technology, high-fa electronic watches are being produced that incorporate various additional devices in their electronic circuit configurations. Electronic watches with alarms have also been provided with other additional devices, such as Nutvub watches, world clocks, calculators, and the like. These electronic watches require easy and reliable operating means for additional devices. These operating means require switch means for adjusting the time (9:09:01 decoration), adjusting and switching the alarm time, switching with additional devices, and controlling. In order to reduce the number of buttons from the viewpoint of design, waterproofness, and usability, conventionally, the operation button for operating the button from the outside has been made up of multiple operation buttons. For example, the position of the push-in, pull-out, and pull-out may be performed in multiple stages depending on the direction of rotation.

The electronic clock with alarm is one that sets an alarm at a predetermined time and emits an alarm sound when the clock time matches the alarm time. However, there are cases where the user wants to hear the alarm sound at a time other than the set time of the Okinami Ktd alarm (currently called preview listening). For example, when purchasing H1. It is also necessary in watch manufacturing to check whether the alarm function is normal. However, when listening to the alarm, it was necessary to adjust the alarm time to the current clock time. Therefore, in order to easily listen to an alarm at any time, conventional alarm listening has been performed by using a special button or by operating a plurality of buttons condensed. ]7 However, from the design, waterproof, and usability standpoints, increasing the number of buttons is not a good idea. However, if the number of buttons is reduced and a single button is provided with multiple functions, the operation method tends to become complicated due to the increasing number of additional devices. In addition, adding an alarm listening function would require an even more complicated operation method, so it would be necessary to sacrifice operability, improve the precision of other additional functions, or provide a specific button. It was necessary to increase the number of buttons, and if this was not possible, it was customary not to include an alarm preview.

The present invention has focused on such drawbacks and provides an electronic time side with an alarm that allows a single button to have multiple functions and allows users to listen to the alarm sound at any time with a simple operation. This will be explained below with reference to the drawings.
