Abstract: Needle insertion mechanisms include a housing and a needle holder, the needle holder being linearly guided by the housing to be moved along the needle-axis. A slider linearly guided by the housing and transversally moveable with respect to the needle-axis from a first to a second slider position. The needle holder is operatively coupled to the slider when the slider is in the first position, thereby retaining the needle holder in a retracted position against the bias of a spring acting on the needle holder. In the second position the slider is decoupled from the needle holder and the holder is moved into an inserted position by the spring. A blocking member arranged between the slider and the housing blocking movement of the slider into the second position, is moved by an active drive thereby unblocking the movement of the slider and subsequently moving the slider to the second position.

Abstract: Needle insertion mechanisms for an injection device include a housing, a needle holder holding a needle, a slider moveable from a first position retaining the needle holder in a retracted position towards a second position allowing movement of the needle holder to an inserted position. An intermediate member positioned between the needle holder and the slider is moveable from a blocked position to a release position releasing the needle holder for movement to the inserted position. A biased gearing between the intermediate member and the needle holder biases the intermediate member towards the release position. A lock between the intermediate member and the slider is configured to lock the intermediate member in the blocked position against the bias of the gearing. Movement of the slider towards the second position unlocks the lock and the biased gearing moves the intermediate member into the release position thereby releasing the needle holder.

Abstract: In an indicating instrument (1) with a translucent dial (8), an illuminated pointer (4) is arranged, out of the viewing direction of a viewer, behind the dial (8) on its rear, inner side (7). An additional covering glass for protecting the pointer (4) can thus be dispensed with.
