係合して抽出するものがある。 The shift device for extracting the required single comb-shaped type bar is, for example, firstly disclosed in Japanese Patent Application Laid-open No. 54-78221.
As described in the Japanese Utility Model Publication No. 54-28013, comb-shaped type bars held by springs are extracted using a motor-driven pinion and rack mechanism, and the second type is that each comb-shaped type bar is extracted as described in Japanese Utility Model Publication No. 54-28013. The third method is one in which a belt is extracted using a belt drive mechanism by supporting the shaft so that it can move in the axial direction.
51-65015), the contents of the specification and drawings attached to the application were photographed on a microfilm, and there is one in which the protrusions on both sides of a comb-shaped type bar are engaged with a link mechanism to extract the text.

However, in the first example, these conventional shift devices have a complicated structure in which each comb-shaped active bar is supported by a spring, and the movement for moving in and out is a motor-driven pinion and rack mechanism. If we try to arrange these on both sides of the comb-shaped type bar to make the extraction operation smoother, the configuration becomes complicated, and in the second example, the guide rods that extend the entire length of the comb-shaped type bar are placed on each bar. In the third example, the structure is complicated and the comb-shaped type bar enters and exits in the axial direction, making it large in size. Since the extraction mechanism is a link mechanism, a rotary motion to linear motion conversion mechanism is required to make it motor-driven, and in order to extract the comb-shaped type bar with high precision by equalizing the movement of the link mechanisms on both sides. However, there are problems such as a complicated structure due to the need for strong and highly precise members.
