Requires a mechanism with high accuracy,
Also, in the case of driving by an electromagnetic mechanism, not only the structure becomes complicated because an effective bell sound is generated, but also the number of constituent parts of the drive circuit tends to increase because a special pulse is generated from the drive circuit. there were. Therefore, since the structure of the device becomes complicated, it is difficult to assemble and adjust, which causes a decrease in reliability of performance, and the occupied space in the timepiece structure becomes large, resulting in high manufacturing cost as a whole. There was a problem of becoming.

接点から離れるように構成されている。In order to achieve the above object, the present invention comprises a yoke composed of a plurality of magnetic pole pieces in which the outer circumference of a disk is bent at a right angle, and an electromagnetic coil is housed therein. A fixed iron core is fitted in the central hole, and the fixed iron core is fixed to the inner bottom portion of the yoke. A movable iron core is slidably provided in the central hole of the electromagnetic coil so as to face the fixed iron core.
A push bar made of a non-magnetic material is projected from one end of the movable iron core, and the other end is freely attracted and engaged with the armature so as to be separated. Further, a contact mechanism of a pair of spring materials is installed outside the bottom of the yoke, and is connected in series as a switching element to the drive circuit of the bell hammer device. The contact spring of this contact mechanism comes into contact with the push bar of the movable iron core and normally contacts the fixed contact by its own elastic bias, and at the same time presses the push bar to restore the armature,
When the armature is sucked, the push bar pushes the armature away from the fixed contacts.

継続し、連続して打鈴音を発するSince the striking device of the present invention is constructed as described above, the electromagnetic coil is energized when the drive circuit is closed by a wake signal or the like, the armature is attracted by the magnetic force generated in the yoke, and the striking ball is removed from the phosphorus. Simultaneously with the separation, the contact spring is pressed by the push bar to separate from the fixed contact, and the drive circuit once opens. Then, the armature is restored by being pressed by the elastic force of the contact spring via the push-in bar, and thus the movable iron core, and at the same time when the striking ball hits the contact spring, the contact spring again contacts the fixed contact and the drive circuit is closed. Therefore, the first wakeup signal returns the drive circuit to the closed state, and this series of operations continues until the wakeup signal ends and the drive circuit is opened, and the bell sound is continuously issued.

FIG. 1 is a sectional view and a side view of an essential part showing an embodiment of a belling device according to the first invention. As shown in the drawing, a yoke 1 is screwed to a support frame A forming a part of an alarm clock main body frame. It is fixed by (not shown) and has four bent magnetic pole pieces 1a. A fixed iron core 2 is fixed to the bottom of the yoke 1, and the fixed iron core 2 is fitted in a central hole of an electromagnetic coil 3 incorporated in the yoke 1. A hinge portion 1b is formed on one of the magnetic pole pieces 1a (the lowest portion in the figure), and the hinge portion 5a of the armature 5 is pivotally supported by the hinge pin 4. Further, as shown in FIG. 1 (b), the armature 5 has a spring shumoku 6 fixed to the upper part thereof, and the movable iron core 8 has a tip end engaged with the center part thereof. A push bar 9 made of a non-magnetic material such as plastic is projected from the rear end of the iron core 8. The electromagnetic coil 3
The center hole is set to have a hole diameter that allows the movable iron core 8 to be freely inserted and removed even if the movable iron core 8 is inserted and removed. The contact spring 10 and the fixed contact 12 are a pair of contact mechanisms each made of a spring material, and one end thereof is fixed to the support frame A. The contact spring 10 normally presses the push bar 9 of the movable iron core 8 while keeping the contact state with the fixed contact 12 by its own elastic bias, and rotates the armature 5 to the restoration position.
The tip 7 of the hammer 6 holds the phosphorus 13 in a belling state. Reference numeral 14 is a fixing screw of a pair of contact mechanisms including the contact spring 10 and the fixed contact 12.

FIG. 2 is a circuit diagram for driving the striking device of the present invention. In the figure, S 1 is a first switch that is closed by an audible signal from a watch or the like, and S 2 is a second switch that turns on and off between the contact spring 10 and the fixed contact 12. Therefore, when the switch S 1 is closed by the wake-up signal, the electromagnetic coil 3 is energized, and a magnetic field passing through the magnetic material yoke 1, the armature 5, the movable iron core 8 and the fixed iron core 2 is generated. As a result, the armature 5 is attracted to the yoke 1 and pivots on the hinge pin 4, so that the hammer 6 is swung toward the yoke 1 side and the hitting ball separates from the phosphorus 13 (broken line state in FIG. 1).

The same parts as those in FIG. 2 are given the same reference numerals as the fixed iron core 2 and the electromagnetic coil 3, and the rear protruding portion push bar 9 of the movable iron core 18 is also the same. However, in the case of the second invention, a hinge portion is not formed on the magnetic pole piece 11a of the yoke 11, and the movable iron core 18
An armature 15 is fixed at a right angle to the tip of the, and a shamoku 16 is attached to the outside thereof.
Further, the lower end portion 16b of the slum 16 is the support frame 1
It is fixed to 9A with screws or the like, and a ball 17 is attached to the upper end 16a. Therefore, when the electromagnetic coil 3 is energized, the movable iron core 18 slides horizontally (in the case of the figure) in the central hole of the electromagnetic coil 3 together with the armature 15, vibrates the spring-like shumm 16 and strikes the phosphorus 13.

The following effects are achieved. A spring material is attached to one end of a movable iron core that is electromagnetically driven, and a push bar made of a non-magnetic material is projectingly provided on the other end to penetrate the fixed iron core and the yoke, and the pair of tips is attached at the tip. Since the movable contact spring of the contact mechanism of the spring material is pressed, the contact mechanism constructed in the drive circuit of the movable iron core is turned on and off, and therefore the vibration of the spring-like shrimp is highly efficient and stable. Since it is not necessary to provide a complicated and highly accurate mechanism like the motor drive system and it is not necessary to generate a special pulse from the drive circuit as seen in the conventional electromagnetic mechanism. The circuit configuration is extremely simple, and the number of parts can be greatly reduced. Further, since the structure is simple and compact, the mechanical parts are small and have a simple shape, the parts can be manufactured and adjusted easily, the reliability can be improved, and the manufacturing cost can be reduced.
