At least one embodiment of the invention relates to the fastening and fitting of a built-in unit on a switchboard, which has a through-opening for this purpose, a collar, which is arranged on the built-in, limiting the action of plugging through the built-in unit, and at least one fixing and clamping device ensuring that the built-in unit is pressed correspondingly against the switchboard. In order to specify simple fastening including fitting which can be carried out by a single person, at least one embodiment of the invention proposes that holders arranged on both sides of the built-in unit and having mounts with holding lugs, which are arranged thereon and engage in corresponding depressions and/or apertures of the built-in unit, are provided, that each mount has a web, on which a slide, which latches in stepwise, can be moved toward the switchboard rear side, as a result of which it presses the holding lugs against the depressions and/or apertures and thus fixes the built-in unit in the through-opening first in the intended position, and that sealing of the through-opening takes place by means of clamping elements, which press against the switchboard rear side.

A liquid jet recorder having a jet ejecting arrangement, and which is connected to a pressure medium conduit for the jet-like ejection of an electrically-conductive recording liquid against a spot on a recording carrier. The liquid ejecting arrangement consists of a plurality of jet nozzles wich are jointly supplied from a common pump, which are so directed that the liquid jets ejected therefrom impinge directly adjacent each other against the recording carrier, and the liquid jets from all nozzles penetrate through a common control electrode. The number of jet nozzles in the inventive liquid jet recorder is coordinated with the desired image results and with the desired recording velocity.
