Cassette loading device having decreased loading effort

Abstract

A cassette loading facility has a guide frame arranged on a chassis in a fixed position. A receiving device is movable between a loading position, in which a cassette can be introduced and removed therefrom, and an operating position. The cassette is positioned on the chassis by means of positioning pins and catch apertures which are formed on the cassette housing. The catch apertures lock the cassette during its transportation between the loading and the operating position and also center it in the operating position. Instead of a fixed arrangement on the drive chassis, the positioning pins are fixed on a first pivoted lever which is pivotally mounted on the cassette receiving device and which can be pivoted into a first position in which the positioning pins release the cassette so that the cassette can be introduced into the cassette receiving device and removed therefrom, and can be pivoted into a second position in which the positioning pins engage with the catch apertures of the cassette whereby the pivoting of the first pivoted lever from the first position into the second position and vice versa is carried out at the loading position of the cassette receiving device. The cassette is locked in the cassette receiving device during its loading or unloading process by the positioning pins engaging with its catch apertures. Upon reaching the operating position, the lower ends of the positioning pins each engage with correspondingly arranged centering apertures in the chassis.
