At this time, the rotary electronic parts are inserted into the holes (not shown in the figure) of the printed circuit board 7 by inserting the protrusion 1 g of the housing 1 into While the substrate 7 is positioned, the rotary electronic component is mounted in a state where the shaft portion 3 a is perpendicular to the surface of the printed substrate 7. In this way, by arranging the switch section 10 in the hollow section 1a, the overall installation area of the rotary encoder and the switch section 10 can be reduced and reduced in size. At the same time, the central section and the hollow section 1a will be operated. An operating member (not shown) of the switch section 10 and the shaft section 3 a are arranged coaxially to improve the operation performance. In addition, in the above embodiment, although the rotary encoder is taken as an example-12- This paper size applies the Chinese National Standard (CNS) A4 specification (210X 297 mm) 518623 A7 B7 Intellectual Property Bureau of the Ministry of Economic Affairs® Industrial and Consumer Cooperatives Printed 5. Description of Invention (10), but it may be a rotary electronic component such as a rotary variable resistor. Further, while the contact piece 4 is provided on the casing 1, 'the conductive pattern 2 is provided on the rotating body 3.' Furthermore, a part of the mounting member 6 other than the mounting piece 6 c may be engaged with the cutout portion 5 d of the plate spring 5. With the rotary electronic component of the present invention, the support portion 5 c of the leaf spring 5 is placed on the upper end surface 1 h of the side wall 1 d, and the upper panel 6 a of the mounting member 6 is placed on the support portion 5 c. It can be assembled in a stack-up type. Compared with the conventional method of riveting a leaf spring to a fixing portion of a mounting member, its assembly performance is better, and it is possible to provide inexpensive rotary electronic parts. In addition, since the support portion 5c of the plate spring 5 is sandwiched between the upper end surface 1h of the side wall 1c and the upper panel 6a of the mounting member 6, the plate spring 5 can be firmly attached. In addition, the support portion 5 c may slightly protrude outward from the wrist portion 5 a accommodated in the accommodation portion 1 e, so that the outer shape of the leaf spring 5 can be reduced. In addition, the mounting piece 6 c is located in the cutout portion 5 d, and the mounting piece 6 c and the support portion 5 c are engaged, so that the support portion 5 c can be firmly clamped between the upper end surface 1 h and the upper panel 5 a. , The leaf spring 5 can be firmly installed. Furthermore, when a mounting member 6 made of a thin metal plate is used, when one end of the mounting piece 6 c is bent toward the casing 1 side, the central portion of the upper panel 6 a is lifted forward and bent, thereby making the upper panel The outer periphery of 6 a is separated from the upper end by 1 h.

Description of the invention (剠) (Please Read the precautions on the back before filling this page) However, since the mounting piece 6 c is located on the notch 5 d, the outer peripheral portion of the upper panel 6 a on the mounting piece 6 c is not from the upper end 1 h side When separated, the support portion 5c can be reliably pressed, and at the same time, the mounting member 6 can be made of a thin material, which reduces the cost of the material. In addition, since the curved portion 5 e is provided on the support portion 5 c, and the curved portion 5 e is sandwiched between the upper panel 6 a and the upper end surface 1 h of the side wall 1 d, no gap is generated, and the support can be firmly clamped and supported. The part 5 c makes the installation of the leaf spring 5 more firm. In addition, the mounting member 6 is provided with a mounting leg 6 d which is bent from the upper panel 6 a and extends backward, and can be mounted on the printed substrate 7. Therefore, the mounting of the rotary electronic component to the printed substrate 7 is easier and stronger. At the same time, the switch section 10 can be arranged on the printed circuit board 7 in the hollow section 1a, so that it can be miniaturized and have good operability. In addition, while the side wall 1 d is formed into a cylindrical shape, the upper end surface 1 h covering the side wall 1 d and the upper panel 6 a in front of the accommodating portion 1 e are formed into a ring shape, so that compared with the conventional quadrangle, It can be miniaturized, reduce material costs, and obtain cheap products.
