In an example, a transmission may include a driven gear attached to a module housing of the imaging module. Further, the transmission may include a retention nose fixed or attached to the module housing. The retention nose may engage with a retention shelf of a drive housing and may retain the module housing to the drive housing such that the driven gear is operably engaged with a drive gear attached to the drive housing.

Apparatus for making flying impressions of type symbols by the use of two or more side-by-side impact wheels extending in planes parallel of the plane of a disklike-type carrier and spaced laterally therefrom. A rocking lever pivoted intermediate its ends forms the printing hammer and is actuated by coupling members independently engaged between the teeth of the rotating impact wheels. The impact wheels have teeth spaced one-half pitch apart, where two wheels are used. The teeth correspond to the characters on the type carrier, and each impact wheel has onehalf the number of teeth as the number of characters on the type carrier. The impact wheels are coupled to the type carrier to rotate therewith. The coupling members are actuated by electromagnets energized by an energy storer for the printing energy, and are selectively engaged between the teeth of the thrust wheels by the electromagnets, to actuate the rocking lever to effect the high-speed making of flying impressions of selected-type symbols. In a modified form the rocking lever moves between two stops and engages a vertically guided hammer, and moves the hammer radially to strike a recording medium against the type carrier and returns the hammer on its return stroke.

A print train of predetermined length and comprised of a plurality of type carrying blocks is provided with an increased number of hammer impactable type characters to thereby enable the realization of significantly accelerated printing speeds, the type blocks being individually and alternately driven to advance a toothed belt to which the blocks are separately coupled around a pair of rotatable sprockets, said accelerated printing speeds being realized without an accompanying degradation of printing quality resulting from the closer spacing of the adjacent characters, means being provided to shield the characters adjacent to an impacted character against the striking force of the hammer associated with such impacted character.

A machine for printing a strip of connected labels including a stack of co-axially disposed print wheels, a series of print wheel setting knobs disposed on an exterior surface of the machine and drivingly connected respectively with the print wheels by means of toothed intermediate wheels and racks and pinions for rotatably adjusting the individual wheels, a solenoid for moving the print wheels out of engagement with the intermediate wheels, and a feed wheel having a print backup boss disposed to have a nip with printing surfaces of the print wheels so that the label stock is printed as the backup boss makes a nip with printing surfaces on the print wheels as the print wheels are collectively rotated with corresponding rotation of the feed wheel.

摘要:
In a print head for a powder jet image forming apparatus according to the present invention, a grid electrode is provided between first electrodes and a developer supply roller in parallel with major surfaces of an insulating layer, and therefore, a distance between any of the first electrodes and the grid electrode is kept fixed. Thus, applying a given level of voltage to the grid electrode allows an electric field for supplying developer to the first electrodes to arise uniformly. This is effective in avoiding uneven density in the resultant image.
