In spite that I had planned an innovartive one, but the client prefers the standard type such as the last AL107-BINO.This is the center base bar that represents the core of the slide mount.
Another innovative idea is coming for the new SKY90-BINO. It is very easy for me to produce the tratidional type of binoscope that had already made for many times, but there will be no thrill in making such banal ones.
I found the light weigt mount I had made for the commercial binocular can be used on the smaller EMS-BINO. So,I have made a simple holder as a prototype.
I will show the pictorial above to explain the mechanism of X-Y knobs.
The three screws on the left EMS (first) housing are the first step to understand the X-Y adjusting mechanism on the right EMS. In the case of the left EMS, vertical or horizontal image shift can be caused by turning a pair of the screws at a time, with the green circled screw in common. Note that all of the three screws are pull ones. and the single center set screw is the pushing one to adjust the height of the mirror surface. So, if you replace the green circled pulling screw for a pulling mechanism by a coil spring you can move the image in the X(blue) and the Y(red) directions respectively by each single knob.
I am adding the diagram because the former image seems to be difficult to understand. 当初の説明図が分かりにくいようなので、追加の図を作成しました。(2025,2/18) ネジの操作は2本ずつセットで行う、ということです。シーソーの原理なので、片方を締めるためには、相手のネジを緩める必要があります。下にシーソーの絵を挿入しますね。
