高くなるという問題があった。(Problem to be solved by the invention) However, in the former case, since the card is provided at the tip (outward) of the contact portion, each movable contact piece becomes unnecessarily long, and the main body growing. Therefore, there is a method in which a hole is provided in the middle between the fixed end of each movable contact piece and the contact part, and a card is inserted through it, but in order to ensure the strength of the perforated part, the movable contact piece must be made wide. First, there was the problem that the main body became taller.

また、後前にあっては、電磁石部の上に接点機溝部を搭
載ずろため、当然に本体は高くなり、大型化していた。Furthermore, in the rear and front sections, the contact machine groove section was mounted above the electromagnet section, which naturally made the main body taller and larger.
