| 摘要 |
The present invention refers to a housing with an ejection mechanism for storing a recording support carrier element or the like, having a top panel (1), sidewalls (3, 4), a back wall (2) between the sidewalls, an elongated insertion/ejection opening for the recording support carrier element or the like, and a spring (12) associated with one (3) of the sidewalls so as to apply a sideways force to the carrier element (20) when the latter is in a fully inserted position in the housing and to apply a force having a component in an ejection direction to the carrier element when the latter assumes an ejection position that is rotated with respect to the fully inserted position. The other sidewall (4) is joined to the back wall by an angled wall portion (14) and there is a support surface (13) between the sidewall (3) having the spring and the back wall, the said angled wall portion and the support wall being arranged in such a way that, when the carrier element is in the fully inserted position and manual pressure is applied to its front side adjacent the other sidewall, a first rear corner of the element will slide along the angled portion and a second rear corner of the element will slide on the support surface in a pre-ejection movement which is carried out substantially without friction contact between the carrier element and the side and back walls of the housing. An elastic catch (25, 26) is also described, which prevents unintentional ejection of the carrier element from within the housing whilst permitting intentional insertion and ejection thereof. A carrier element manipulator (37) is also provided in the upper panel (1) of the housing, which permits withdrawal of a cassette from the carrier element (cassette box) and its return thereto, using only one hand. |
