<p>In a reading apparatus a work support (2), on which a record carrier such as a book or magazine can be placed, is supported by a stand (1). For the vertical adjustment of the work support (2) the stand comprises two upwardly directed longitudinal guides (3, 4) which extend parallel to ona another. Moreover, the work support (2) is movable in a horizontal direction relative to the stand (1). Between the stand (1) and the work support (2) there is arranged a weight compensation means (33) and a latching device (37). The latching device (37) comprises a latching rod (8) arranged between the longitudinal guides (3, 4) and a latching lever (38) which extends transversely of said latching rod (18) and which is provided with a hole (39) through which the rod extends. The latching lever (38) is pivotally connected to the work support (2) and is urged into an oblique position relative to the rod (18) by a spring (41). Near the end of the latching lever (38) which is remote from the latching rod (18) the lever is connected to an elastic hook (42), which is coupled to an actuating rod (43) which is arranged on the work support (2) and which is slidable in a horizontal direction. The actuating rod (43) is connected to at least one control lever (44, 45) on the sork support (2).</p> |
