On the surface of an insulating substrate 51 made of ceramics or the like, an arc-shaped resistor 5 2 is provided around a hole (not shown) provided at the @center portion, and an end portion of the resistor 5 2 is provided at the same time. An electrode portion 53 is provided as a terminal. The rotating body 5 4 made of a metal sheet includes an upper panel 5 5 and a disk-shaped expansion portion 5 6 that expands the center of the upper panel 5 5 downward, and a connection portion 5 7 to the upper panel 5 5. At the same time, the connecting portion 57 is bent into a U-shaped sliding piece 5 8 below, and a cross-shaped screwdriver slot 59 is formed across the upper panel 55 and the expansion portion 56. Printed by the Intellectual Property of the Ministry of Economic Affairs / Employee Consumer Cooperative, and the expansion portion 56 has a bottom wall 56b with a hole 5 6 a. At the same time, the slot portion 5 9 a of the screwdriver slot 5 9 is located on the upper panel 5 5 The center c is connected to the line S where the central portion of the lateral width A of the connecting portion 57 is connected. In addition, the rotating body 54 constructed in this way is configured by a metal sheet disposed on the lower portion of the insulating substrate 51 in a state where the bottom wall 5 6 b of the expansion portion 56 is placed on the insulating substrate 51. The projection of the terminal 6 0 (not shown in this paper is fully applicable to the Chinese National Standard (CNS) 8-4 specifications (210X 297 mm) -4- 538417 A7 B7 V. Description of the invention (2)). Hole 5 6 a. Then, the protruding end of the terminal 60 is riveted so that the rotating body 5 4 is mounted on the insulating substrate 51 and is allowed to rotate, and at the same time, the sliding piece 5 8 is in contact with the resistive body 5 2. status. With such a structure, a chip-shaped variable resistor is formed. If a cross-head screwdriver (not shown) is inserted into the screwdriver slot 5 9 to rotate the rotating body 5 4, the rotating body 5 4 uses the terminal 6 The protrusion of 0 rotates around the axis, and at the same time, the sliding piece 58 slides on the resistor 52 to adjust the resistance 値. In addition, since the groove portion 5 9 a of the screwdriver groove 5 9 is located on the cliff S that connects the center C of the upper panel 5 5 and the central portion of the width A of the connecting portion 57, the upper panel 5 5 The central portion of the connecting portion 57 connected to the sliding piece 5 8 is thinner and its strength is reduced. Therefore, when the rotating body 5 4 is rotated by the screw B, the connecting portion 5 7 is distorted and bent, which affects the sliding. The normal rotation of the sheet 58. (Problems to be Solved by the Invention) In the conventional chip variable resistor, the slot portion 5 9 a of the screwdriver slot 5 9 is located to connect the center c of the upper panel 5 5 and the center portion of the width A of the connection portion 57. Line S, the center portion of the connecting portion 57 connecting the upper panel 5 5 and the sliding piece 5 8 becomes thinner and its strength decreases. Therefore, when the rotating body 54 is rotated by a screwdriver, the connecting portion 5 7 will cause distortion and bending, affecting the normal rotation of the sliding plate 58. Therefore, the purpose of the present invention is to provide a paper ruler that can increase the connection part. It is applicable to the Chinese National Standard (CNS) A4 specification (210X297 mm) (please read the precautions on the back before filling this page).

The Phillips screwdriver slot 7 'on the panel 6 is bent into a U-shape, and the base 9 and the upper panel 6 are stacked on top of each other. At the same time, the setting position of the groove portion 7 a of the screwdriver slot 7 is separated from the paper. And applicable Chinese National Standard (CNS) M specifications (210x297 mm) (please read the precautions on the back before filling out this page), 1T Wisdom of the Ministry of Economic Affairs 4¾ Printed by the Employee Consumer Cooperative -10- 538417 A7 B7 V. Description of the invention (8). The center C of the upper panel 6 and the horizontal portion of the connecting portion 8 The line S connecting the central portion of A, therefore, the central portion of the connecting portion 8 is connected to the upper panel 6 at a wider portion 6 and its strength is increased. Therefore, when the rotating body 5 is rotated by a screwdriver, the connecting portion 8 will not produce twists and bends, and the basic reference [3 9 can rotate normally without affecting the sliding part 9 a. In addition, two adjacent groove portions 7 a of the screwdriver slot 7 are arranged at positions symmetric to the connection line S of the center c of the upper panel 6 and the center portion of the width A of the connection portion 8. Therefore, the central portion of the connecting portion 8 is connected to the upper panel 6 at its wider portion 6 b, and the strength can be increased. Furthermore, the groove portion 7 a of the screwdriver groove 7 is located on both sides of the line S connecting the middle portion of the upper panel 6 and the central portion of the width A of the connection portion 8, and the opposite 2 The groove portions 7 a and the front end portion 7 b are located close to the connection portion 8. The width A of the connection portion 8 formed at the same time is equal to or exceeds the front ends of the two groove portions 7 a which are close to the connection portion 8. The width B between the sections 7b. Therefore, the width A of the connecting portion 8 can be increased, and the strength can be further increased. In addition, the central portion of the base portion 9 is provided with a swollen portion 10 having a recessed portion 10 a in the central portion in a state connected to the base portion 9, and a part of the recessed portion 10 a faces the screwdriver groove 7. Lower, the upper panel 6 is located on the expansion part 10, so the screwdriver is inserted into the screwdriver groove 7 and Ken goes deep into the recess 10a, which is easy to operate during adjustment.
