め、しだいにピン２が緩み、回路基板１との接触
不良をおこし、導通不良となるおそれがあつた。 The conventional electronic needle alignment switch structure, as shown in FIG. 1, involves fitting a pin 2 forming an electrical contact into a hole 1a formed in a circuit board 1, and then soldering it.
It was fixed to the circuit board 1 by a method such as soldering or caulking. Furthermore, the rising portion 2a of the pin 2
The switch spring 3, which is provided so as to be able to swing freely, is brought into contact with or released from the contact to activate the switch.
It was turned on and off. However, with such a structure, not only does it take time and effort to install the pin 2, but the cost increases due to brazing, soldering, and caulking, and the pin 2 itself is set high in the thickness direction, so the entire switch mechanism The thickness of the device had become so thick that it was impossible to make it thinner. Further, when the switch spring 3 comes into contact with the pin 2, a certain impact force is applied, so that the pin 2 gradually loosens, resulting in poor contact with the circuit board 1, which may result in poor conduction.

ON,
By turning it off, the structure is simplified, making it suitable for thinning, and providing a highly reliable switch mechanism.

台ピン１１を回転中心軸とし、左右回動する。 The present invention will be explained in detail below with reference to FIGS. 2, 3 and 4. FIG. 2 is a plan view of the electronic needle setting switch mechanism of the present invention, in which the main plate 4, the second main plate 5,
It is composed of a winding stem 6, a winding stem positioning member 7, a switch lever 8, a contact lever 9, a switch lever spring 10, a winding stem cradle pin 11, and a circuit board 1, and the winding stem 6 is made of plastic resin. By pulling the winding stem 6 to the second stage guided by the second main plate 5, the winding stem positioning member 7 is activated, and at the same time, by passing over the winding stem protrusion 6a, a click feeling is expressed and the winding stem 6 is pulled to the second stage. By engaging the cam portion 6b formed on the winding stem 6 and the switch lever protrusion 8a to rotate the winding stem 6 left and right, the switch lever 8 is interlocked with the winding stem 6 and the winding stem holder pin 11 as the center axis of rotation, and rotates left and right.

ゾ下に配置してある。 In addition, the cam portion 6b formed on the winding stem 6 has a larger cam angle when the winding stem 6 rotates in the A direction, so that the cam portion rotates in the A direction to allow escape due to elastic deformation of the switch lever 8. The contact lever 8 is shaped like an ellipse so that the left and right rotational movements of the contact lever 8 have the same stroke. Further, the hole 8b formed in the switch lever 8 and the contact lever arm 9a are interlocked, and the pin 9 connected to the contact lever 9 is inserted into the hole 5a formed in the second base plate 5 and the hole 1b formed in the circuit board 1.
b engages with the contact lever 9 and becomes the center of rotation of the contact lever 9, and the protrusion 9 formed on the contact lever 9
At c, the switch operation is turned on and off by contacting the electrode part 1d formed on the bottom surface of the circuit board 1.
Normally, the contact lever protrusion 9c is located in the hole 1c formed in the circuit board.
located within. Furthermore, a switch lever spring 10 for returning the contact lever 9 to its normal position is engaged with the switch lever arm 8c, and
The switch lever spring 10 is guided by a lever spring fulcrum pin 12 and a lever spring positioning pin 13.
At points a and 10b, the contact lever 9 returns to its normal position. Further, the switch lever 8 is arranged below the winding stem 6 tenon.

By rotating left and right, the switch lever 8 is rotated by the cam portion 6b formed on the winding stem,
Furthermore, the contact lever 9 that is interlocked with the switch lever 8 rotates, and the protrusion 9c formed on the contact lever is rotated.
, it comes into contact with the electrode portion 1d formed on the lower surface of the circuit board 1. Further, the contact lever 9 returns to the normal position by the switch lever spring 10 engaged with the switch lever 8.
