Solenoid body 23 housing solenoid 22
is formed in the shape of a box frame with openings on the front and rear sides, and is sandwiched between the mounting plate 20 and the base plate 13, and is attached to the two protrusions 24 provided on the base plate 13 and the mounting plate 20. It is fixed by hooking the opening part. The plunger 25 of the solenoid 22, which is moved up and down with respect to the solenoid body 23, or its upper and lower ends protrudes from the upper and lower surfaces of the solenoid body 23.

Like the solenoid body 23, the drive body 26 is formed in the shape of a box frame with open front and rear surfaces, and is fitted so as to surround the solenoid body 23 from the outside. The upper and lower plates are attached to the upper and lower ends of the plunger 25 via U-shaped grooves 27a and 27b, respectively, so that the driving body 26 and the plunger 25 act as guide parts that slide on the left and right sides. It is configured to be movable up and down using the side surface of the main body 23 as a guide. Note that a plunger 2 is provided between the lower part of the driver 26 and the solenoid body 23.
A return spring 28 wound around the plunger 25 is loaded and acts to always urge the plunger 25 downward. Furthermore, the vertical movement of the front and rear opening end surfaces of the driving body 26 is guided while being in sliding contact with the substrate 13 and the mounting plate 20, respectively.

An actuating piece 29 is protruded from the substantially lower front surface of one side plate 26a of the drive body 26, and this actuating piece 29 passes through the guide groove 17 and extends to the side of the guide piece 8. The operating shaft 9 is loosely fitted into an engagement groove 30 formed in the engagement groove 30 .

Next, the operation of this embodiment configured as above will be explained.

Now, when the solenoid 22 is excited by the action of the detection device according to the predetermined winning condition, the plunger 2
5 is raised against the elasticity of the spring 28, and the driving body 26 is moved upward together with the plunger 25 mainly using the left and right side surfaces of the solenoid body 23, the base plate 13, and the mounting plate 20 as guides.
