Abstract
A signal converter for use in a recording or displaying device which can be used to change the size of characters to be recorded or displayed. By using instruction signals or enlargement codes, a part (for example the upper or lower half) of a character field and hence a corresponding part of a character may be enlarged, and then the enlarged upper and lower halves are combined to form an enlarged character for recording or display. Any number of characters in a row of characters may be changed in size by using the signal converter, and specified portions of different characters may be enlarged and then combined.
Claims23
A character size changing device comprising:
- (a) pattern signal output means responsive to an input information signal for developing pattern signals;
- (b) pattern output means responsive to the pattern signals developed from said pattern signal output means for producing visible character patterns;
- (c) storage means for storing therein information signals to be applied to said pattern signal output means and instruction signals for designating a part of the visible patterns to be produced by said pattern output means and specifying the size of the visible patterns;
- (d) read-out means for reading out information and instruction signals stored in said storage means;
- (e) transmission means for transmitting the information signals read out from said storage means to said pattern signal output means;
- (f) discrimination means for discriminating the presence of an instruction signal in the signals read out from said storage means;
- and
- (g) control means for controlling said pattern signal output means to cause, when no instruction signal is discriminated by said discrimination means, said pattern signal output means to develop all the pattern signals corresponding to a read-out information signal and to cause, upon detection of a read-out instruction signal, the pattern signal output means to develop a part of the pattern signals corresponding to the part of the visible pattern designated by the discriminated instruction signal.

A character size changing device comprising:
- (a) pattern signal output means responsive to an information signal and a row indication signal for developing pattern signals corresponding to the rows designated by the row indication signal for the pattern signals corresponding to the information signal;
- (b) pattern output means responsive to the pattern signals developed from said pattern signal output means for producing visible character patterns;
- (c) storage means for storing therein the information signals to be applied to said pattern signal output means and instruction signals designating a part of the visible patterns to be produced by said pattern output means and specifying the size of the visible patterns;
- (d) read-out means for reading out the information and instruction signals stored in said storage means;
- (e) delivery means for delivering the information signals read out from said storage means to said pattern signal output means;
- (f) discrimination means for discriminating the presence of an instruction signal in the signals read out from said storage means to produce an output signal;
- and
- (g) control means including row indication signal generating means for generating row indication signals, said control means causing said row indication signal generating means to generate a row indication signal designating one row when said discrimination means discriminates the presence of an instruction signal in the signals read out from said storage means, and said control means causing said row indication signal generating means to generate a row indication signal designating another row when said discrimination means discriminates the absence of an instruction signal in the signals read out from said storage means.

A character size changing device comprising:
- (a) storage means for storing therein information signals and instruction signals designating a part of the information signal to be developed;
- (b) read-out means for reading out the information and instruction signals stored in said storage means;
- (c) pattern signal generating means responsive to an information signal read out from said read-out means for generating pattern signals corresponding to said read out information signal and delivering a sequence of the pattern signals in response to read-out pulses applied thereto;
- (d) pattern output means responsive to the pattern signals developed from said pattern signal generating means for producing visible character patterns;
- (e) delivery means for delivering the information signals read out from said storage means to said pattern signal generating means;

- (g) pulse generating means for generating the read-out pulses in response to which the pattern signals are read out sequentially from said pattern generating means;
- and
- (h) control means for controlling said pulse generating means to cause, when the presence of an instruction signal is not discriminated by said discrimination means, said pulse generating means to generate read-out pulses of a first frequency and to cause, when the presence of an instruction signal is discriminated by said discrimination means, said pulse generating means to generate second read-out pulses of a second frequency different from said first frequency.
