Abstract
Abstract A device for recording characters on a recording carrier uses mosaic recording mechanisms. In addition to the recording of the characters in the required character height, additional recording members are arranged in the recording head and a control device for the mosaic recording mechanism is constructed in an expanded manner so that alternately a height-extended character formation can be executed over all recording members. The device is suitable for recording capital and small letters, and the control apparatus is constructed so that all alternatively the capital letters and numerals can be recorded in an extended manner by an additional amount provided for the short heights of the small letters. The control apparatus for each of the two character heights to be formed by the mosaic recording head has its own character generator and switching means are provided so that the two character generators can be alternately effective for activating the mosaic recording head.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
118 words
A device for recording characters on a recording carrier, comprising: recording means comprising a mosaic recording head including a plurality of first recording members which may be activated to record characters of a first height and a plurality of second recording members which may be activated to extend the recording height to a second height; and recording height control means connected to said recording head and including a signal input, said recording height control means responsive to first input signals to selectively activate said first recording members to record characters of the first height and responsive to alternately received second input signals to selectively activate said first and second recording members to record characters of the second height.
Claim 2
Independent Claim
118 words
A device for recording characters on a recording carrier, comprising: recording means comprising a mosaic recording head including a plurality of first recording members which may be activated to record characters of a first height and a plurality of second recording members which may be activated to extend the recording height to a second height; and recording height control means connected to said recording head and including a signal input, said recording height control means responsive to first input signals to selectively activate said first recording members to record characters of the first height and responsive to alternately received second input signals to selectively activate said first and second recording members to record characters of the second height.
Claim 3
Dependent Claim
132 words
The device of claim 1, wherein said recording height control means comprises: a decoder for receiving and decoding first and second input signals and providing first output signals representing first character signals and first character height signals and second output signals representing second character signals and second character height signals; first and second character generators connected to receive said first and second character signals and provide corresponding character control signals; gating means connected to said first and second character generators to receive said character control signals and connected to said recording means; and gate control means connected to said gating means and connected to said decoder to receive said first and second character height signals and open said gating means for the character control signals associated with the received character height signals.
Claim 4
Dependent Claim
89 words
The device of claim 2, wherein said gating means comprises a plurality of first AND gates each having an input connected to said first character generator and an output connected to said recording means, and a plurality of second AND gates each having an input connected to said second character generator and an output connected to said recording means, and said gate control means comprises a bistable circuit having inputs connected to said decoder and a pair of oppositely active outputs connected to respective ones of said AND gates.
Claim 5
Dependent Claim
12 words
The device of claim 3, wherein said bistable circuit comprises a flip-flop.
Claim 6
Dependent Claim
25 words
The device of claim 3, wherein said recording means comprises an amplifier connected between said outputs of said AND gates and said mosaic recording head.
Claim 7
Dependent Claim
49 words
The device of claim 1, wherein said first recording members correspond to capital letters, said second recording members corresponds to lower case letters, and said recording height control means comprises means for providing an extended height recording of said capital letters by the height of the lower case letters.
