Abstract: When an enlargement print key is pressed, a label producing apparatus enters a mode for setting the enlargement magnification used for enlargement printing. Next, a number key is operated to actually set the enlargement magnification. After the creation of print image data, respective data are taken from a table in which the respective data about widths of printing tapes, the number of printing tape segments based on width of tape and enlargement magnification, and "an enlargement start bit position," "an enlargement end bit position," "an enlargement work start bit position 1," "an enlargement work start bit position 2" and "the number of shifts for adjustment" with respect to each tape width which have been specified to thereby create one-dot string data. When it is desired, for example, to scale up and print data associated with a 12-mm tape width in 3.times. magnification, the enlargement print data is printed on the corresponding printing tape by being divided into three at 12-mm width intervals.

Abstract: A spread spectrum communication device according to the present invention includes a transmitter and a receiver, and suppresses demodulation errors to a minimum value, even if there exit a plurality of narrow band disturbing signals. In the transmitter, a first PN (pseudo noise) code from a fist PN code generator and a second PN code having a delayed phase coming from a shift register are inputted to a multiplexer and switched according to an exclusive logic sum of data and a disturbing signal.

A correlation pulse thus obtained is applied to two AND gates. Two time window pulses are each applied to two multiplexers nd are switched by a control signal, the outputs of the multiplexers being respectively applied to these AND gates.
