In some cases, the liquid crystal element must be located closer to the center of the circular substrate so as not to get too close to the edge of the circular substrate. In addition, when multiple liquid crystal elements are mounted on a board adjacent to each other in the direction in which the pins protrude, they must be mounted with appropriate spacing between these pins so that they do not touch each other. However, it had the disadvantage of requiring a large installation area.

ている。 The liquid crystal element body 2 has two parallel long sides 8 and 9.
passing through the center between and in an asymmetric state with respect to the center line 10,
A plurality of pins 3 are fixedly attached so as to protrude from the two long sides 8 and 9, respectively. That is, on one side of the center line 10, the plurality of pins 3 are spaced apart from each other by a predetermined distance at the center of the long side 8 and arranged as a central pin group 3a, and on the other side of the center line 10, the pins 3 are arranged at the center of the long side 9. They are arranged as a left pin group 3b at a predetermined distance from each other on the left side of FIG. They are spaced apart and arranged as a right pin group 3c, and the left pin group 3b and the right pin group 3c are spaced apart from each other.

る曲げ応力がかかるのを防止するためである。 The pin 3 consists of a holding part 11 and a leg part 12,
The liquid crystal element body 2 is fixedly attached to the liquid crystal element body 2 so that an electric field can be applied to the liquid crystal via the electrodes 6 and 7 while the long side edges of the liquid crystal element body 2 are held between the clamping parts 11. The electrodes 6 and 7 each consist of a segment as shown in FIG. 4, and these electrodes 6 and 7 and each pin 3 are electrically connected as shown in the same figure. In addition, leg part 1
2 is inserted into a pin hole of a socket (not shown) so as to be electrically connected. In addition, the liquid crystal element body 2
The reason why the pins 3 are provided on both sides is to prevent bending stress from being applied to the pins 3 due to external forces.

例の液晶素子１は、円形基板１３の外周端縁に、
大幅に近づけて取り付けることができる。 Therefore, the liquid crystal element 1 configured as described above
When attaching to the circular board 13 of the flowmeter,
Since the number of pins 3 in the central pin group 3a on one side of the liquid crystal element main body 2 is smaller than the number of pins on one side of a conventional liquid crystal element, it is smaller than the conventional liquid crystal element shown by the two-dot chain line in FIG. However, the liquid crystal element 1 of this embodiment shown by the solid line in FIG.
They can be mounted much closer together.
また、複数の液晶素子１を、それらの幅方向に

つて液晶素子１の取り付けの方向性を誤らず、誤
取り付けを防止することができる。 In addition, when a plurality of liquid crystal elements 1 are arranged in the width direction and attached to the flow meter board 14, the center pin group 3a is the left pin group 3b, the right pin group 3c is
Since they are arranged asymmetrically with respect to the center line 10 of the liquid crystal element body 2, the center pin group 3a is located between the left pin group 8b and the right pin group 3c, as shown in FIG. The two do not face each other and come into contact with each other. Therefore, each liquid crystal element 1 can be attached to the flowmeter substrate 14 with zero spacing between each liquid crystal element 1, and thereby the installation area of the liquid crystal element 1 can be reduced. Furthermore, if you try to attach one liquid crystal element 1 to another liquid crystal element 1 side by side in the opposite direction, the left pin group 3b and the right pin group 3c will face each other and collide, making it impossible to attach them. Therefore, the direction of mounting the liquid crystal element 1 can be corrected and erroneous mounting can be prevented.

付けることができ、便利である。 As explained above, according to this invention, a plurality of pins protruding from two parallel sides of a rectangular plate-shaped liquid crystal element body are arranged asymmetrically with respect to a center line passing through the center between the two parallel sides. In addition, since the configuration is such that the pins are provided in different areas on one side and the other side, it is difficult to arrange multiple liquid crystal elements side by side so that the pin-provided sides of the multiple liquid crystal elements are in contact with each other. Even in cases where the pins on one side and the pins on the other side overlap and interfere with each other, the mounting interval of the liquid crystal elements can be made as small as possible. The installation area of the element can be reduced. Further, a central pin group consisting of a plurality of pins is provided at the center of one side edge of the center line between the two parallel sides of the liquid crystal element body, and a left pin group consisting of a plurality of pins is placed at both end sides of the other side edge. If the right pin group is provided asymmetrically with respect to the center line, it is possible to prevent incorrect mounting of liquid crystal elements when multiple liquid crystal elements are installed in parallel, and also to prevent the liquid crystal elements from being incorrectly attached to the edge of the part to be attached such as a board. The liquid crystal element can be conveniently mounted much closer than conventional liquid crystal elements.
