Abstract
Abstract A thermal transfer recording apparatus according to the invention is constructed so that information is recorded by transferring ink from a thermal transfer ribbon to the surface of a transfer sheet by means of a thermal head, and that a second unit can be swung up to be separated from a first unit as required. Sag of the thermal transfer ribbon is removed by feeding the ribbon for a predetermined length when it is detected that the second unit is set on the first unit. Thus, fusion of ink on the thermal transfer ribbon at the start of recording can be prevented.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
136 words
A thermal transfer recording apparatus in which ink on a thermal transfer medium is transferred to an objective material for transfer so that information is recorded on the objective material, and which comprises: a first unit and a second unit swingably attached thereto, said first unit containing therein holding means holding the thermal transfer medium and take-up means driven by a drive source to wind the thermal transfer medium from the holding means, regulating means for regulating the driving timing of the drive source; and detecting means for detecting that the second unit is set on the first unit and outputting a detection signal, wherein said regulating means, receiving the detection signal from the detecting means, causes the drive source to actuate the take-up means, whereby the thermal transfer medium is wound for a predetermined length.
Claim 2
Dependent Claim
136 words
A thermal transfer recording apparatus in which ink on a thermal transfer medium is transferred to an objective material for transfer so that information is recorded on the objective material, and which comprises: a first unit and a second unit swingably attached thereto, said first unit containing therein holding means holding the thermal transfer medium and take-up means driven by a drive source to wind the thermal transfer medium from the holding means, regulating means for regulating the driving timing of the drive source; and detecting means for detecting that the second unit is set on the first unit and outputting a detection signal, wherein said regulating means, receiving the detection signal from the detecting means, causes the drive source to actuate the take-up means, whereby the thermal transfer medium is wound for a predetermined length.
Claim 3
Dependent Claim
44 words
The thermal transfer recording apparatus according to claim 1, further comprising a power switch adapted to be turned on when the second unit is set on the first unit and to be turned off when the second unit is separated from the first unit.
Claim 4
Dependent Claim
24 words
The thermal transfer recording apparatus according to claim 2, wherein said detecting means outputs the detection signal when the power switch is turned on.
Claim 5
Dependent Claim
45 words
The thermal transfer recording apparatus according to claim 3, wherein said power switch has an actuator, and said second unit has a push piece adapted to press the actuator to turn on the power switch when the second unit is set on the first unit.
Claim 6
Dependent Claim
38 words
The thermal transfer recording apparatus according to claim 4, further comprising a case covering the power switch and having a slit through which the push piece can pass when the second unit is set on the first unit.
Claim 7
Dependent Claim
35 words
The thermal transfer recording apparatus according to claim 1, wherein said holding means includes back tension means adapted to apply back tension to the thermal transfer medium while the thermal transfer medium is being wound.
