    摘要: A data conversion unit includes a first input/output unit, a second input/output unit, an encoder, a decoder, a random number generator for generating random number data, and a control unit which selects a first, second and third setting function. The first setting function sets the data conversion unit to input data from the first input/output unit, encode data by the encoder, and output the encoded data from the second input/output unit. The second setting function sets the data conversion unit to input data from the first input/output unit, replace the data with the random number data generated by the random number generator, and output the random number data from the second input/output unit. The third setting function sets the data conversion unit to input encoded data from the second input/output unit, decode the encoded data by the decoder, and output the decoded data from the first input/output unit.

    摘要: The disclosure describes a print tape which allows a separating sheet to be removed easily and quickly without bending the print tape and a tape cassette containing the tape. The print tape is accommodated in the tape cassette and has a tape base material, an adhesive agent layer and a separating sheet. Side portions are each provided adjacent both sides, in a width direction, of the tape base material. A back scoring portion is provided in a center in the width direction of the separating sheet. Therefore, both sides in the width direction of an end portion of the print tape can be gripped and pulled in a direction in which they separate from each other. As a consequence, the separating sheet separates along the back scoring and a center portion of the tape base material is freed for application. Because of the structure, the separating sheet can be peeled easily and quickly from the printed base material without bending the print tape.
