Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to an alarm clock, and particularly to an arrangement structure of a switch operating lever for operating a bell-ringing device in order to make the clock more compact.

(Prior Art) Some alarm clocks in recent years are equipped with a ringing device that strikes a ring using the driving force of a motor.

As an example of this kind of alarm clock,
There is one disclosed in Publication No. 46240.

In the alarm clock disclosed in this document, the clock mechanical body, the battery, the bell-striking device that swings the ring and strikes the ring with a striking ball, and the motor that drives the bell-striking device are located on one side of the mounting plate. They were arranged and installed side by side.

In addition, the ring of the bell-striking device is arranged so as to face the back side of the watch body, and the motor that drives the bell-striking device is arranged so that its output shaft is perpendicular to the mounting plate. This allows more of the ringing sound to be emitted outside the case.

(Problems to be Solved by the Invention) However, this type of alarm clock requires a large installation space as a whole, making it extremely difficult to downsize the clock.

That is, since the timepiece mechanism, battery, bell striking device, motor, etc. are arranged in a plane on one side of the mounting plate, a large mounting area is required, and the timepiece inevitably becomes large. Furthermore, since the output shaft of the motor is disposed perpendicularly to the mounting plate, there is a problem in that the thickness of the watch becomes large.

Therefore, in view of the above-mentioned problems with conventional alarm clocks, the purpose of this invention is to reduce the installation space for the bell-striking device and the operating lever in a clock mechanism body equipped with a bell-striking device, thereby achieving miniaturization of the clock. It is said that

(Means for Solving the Problems) The alarm clock of the present invention has a bell-striking device driven by a motor, a battery box on one side, and the output shaft of the motor of the bell-striking device on the other side. a mechanism receiving plate that can be attached parallel to the other surface; a timepiece mechanism disposed on the mechanism receiving plate so as to overlap the motor and battery box;
A ring is attached to a mechanism receiving plate with an opening facing both sides of the timepiece mechanism body and the motor, and a striking ball that is oscillated by the motor is disposed inside the ring. It is constructed of a housing, and an operating lever for operating a motor switch, which is provided in a gap surrounded by a motor, a clock mechanism, and a battery box so as to be movable back and forth in the longitudinal direction of the battery.

(Function) Therefore, the motor of the bell striking device is installed in parallel with the battery box, and the clock mechanism body is attached to the mechanism support plate so as to overlap the battery box and the motor, and is further surrounded by the battery box, motor, and clock mechanism body. Since the operating lever for operating the motor is placed on the mechanism receiving plate in the space gap, the planar space of the receiving plate can be greatly reduced.Also, since the output shaft of the motor is parallel to the receiving plate, the thickness dimension can be reduced. This allows the watch to be made more compact.

Note that the present invention can be widely used in watches having a bell-ringing device driven by a motor, and is not limited to alarm clocks.

(Effects of the invention) As explained above, according to the invention, the battery box is integrally molded on the mechanism receiving plate, the motor of the bell striking device is provided in parallel with the battery box, and the battery box and motor are overlapped. A switch for operating a switch that controls the operation of the motor is provided on the mechanism receiving plate in the gap surrounded by the battery box, motor, and clock mechanism body. Since the operating lever is arranged, the planar space for installing the operating lever for the bell-striking device including the motor, the battery box, and the motor switch can be significantly reduced compared to the conventional case, thereby making the watch more compact.

Further, since the operating lever is held in a direction perpendicular to its movement direction by fixing the timepiece mechanism to the mechanism support plate, the mounting structure of the operating lever is extremely simple.

Furthermore, since the opening of the phosphor is directed toward the watch mechanism and motor, which are arranged so as to overlap in the thickness direction of the watch, the length to width ratio is approximately 1:1.
Particularly when it is attached to a cylindrical case, it requires a minimum amount of space, and the watch can be made more compact.

In addition, the motor has a mechanism receiving plate, a phosphor mounting base,
Since it is fixed in a state surrounded by the clock mechanism and the clock mechanism body, it becomes a strong connection structure that is resistant to shocks such as dropping.

Furthermore, since the output shaft of the motor is arranged parallel to the mechanism support plate, the thickness of the watch is reduced and the watch is made more compact. This can be set to a large value up to the length of the battery in the longitudinal direction, so the sound pressure of phosphorus is also relatively large despite the miniaturization.
