Positioning device for a sample carrier

摘要

The invention relates to an apparatus (100) for positioning a sample carrier plate, wherein the apparatus (100) comprises a main body (102) for receiving the sample carrier plate, positioning stops (106, 108) which are disposed in opposing first corner regions of the main body and are prestressed for clamping the sample carrier plate and mounted displaceably, an actuating device (114) which is disposed in a second corner region of the main body and is equipped such that by actuating the actuating device (114) the positioning stops (106, 108) can be transferred between an operating state engaging the sample carrier plate and an operating state releasing the sample carrier plate, and comprises a force transmitting element (118) which is equipped to transmit an actuating force from the actuating device to the positioning stops.

1. An apparatus for positioning a sample carrier plate, wherein the apparatus comprises:
a main body for receiving the sample carrier plate; positioning stops, which are disposed in diagonally opposing first corner regions of the main body and are prestressed for clamping the sample carrier plate and mounted displaceably; an actuating device which is disposed at the main body and is adapted such that by actuating the actuating device, the positioning stops can be transferred between an operating state engaging the sample carrier plate and an operating state releasing the sample carrier plate, the actuating device comprises a linear guide device which enables a forward or backward movement for transferring the actuating device between the operating states; a force transmitting element which is adapted to transmit an actuating force from the actuating device to the positioning stops, the force transmitting element comprises a rotatably mounted coupling disk; a coupling rod pivotably connected in an articulated manner by a first rotatable connecting element to the rotatably mounted coupling disk and pivotably connected in an articulated manner by a second rotatable connecting element to the linear guide device of the actuating device, further coupling rods, each of which is coupled to the respective positioning stop and to the rotatably mounted coupling disk, wherein two of four corners of the main body, which is substantially rectangular, are provided with the positioning stops and another one of the four corners is provided with the actuating device as functional components.
