The mode of heat performance color is utilized on paper.That is, it is laminated with paper and heat is sensed and shows color
Fuel, therefore, print image (photo) or text by controlling heating temp or the fever time on head.
Fig. 1 represents conventional photo print machine (1).As illustrated, including：It is laminated with paper (P) substrate (15)；Institute
State the paper-sheets rolling wheel (40) that the bottom surface of substrate (15) protrudes；The paper (P) supplied by the paper-sheets rolling wheel (40) is discharged forwards
Platen roller (30)；It is formed at the top of the platen roller (30) and applies the head of heat to paper (P)
(ThermalPrintingHead,12a)；Control the PCB (13) of heating temp, the fever time on the head etc..Also, institute
State head (12a) and PCB (13) is formed at the bottom of thermal insulation board (12), the thermal insulation board (12) combines with upper case (10), institute
Platen roller (30) is stated to combine with lower case (20).
Reference picture 2, lower case (20) pass through hinge axis (11) and upper case (10) hinge in the front side of platen roller (30)
With reference to.When this is to supply paper (P) between platen roller (30) and head (12a) so that lower case (20) edge
Hinge axis (11) and carry out wobbling action (20- downwards>20').Also, after the upper case (10) and lower case (20)
Side is connected by spring (S), and the upper case (10) and lower case (20) flexibly carry out spinning movement.
Reference picture 3 illustrates the working condition of conventional photo-printer.Such as by (a) can be known, in head (12a) and pressure
It is less than the thickness of paper (P) formed with gap, the gap between paper roller bearing (30).Also, it is built-in with weldering in the PCB (13)

For rotate platen roller (R2) the 1st power transmission section include engaged with the travelling gear (171) and with pressure
The 1st gear (172) that the rotary shaft of paper roller bearing (R2) combines.
For rotating the 2nd power transmission section of paper-sheets rolling wheel (R1), including：The 2nd tooth engaged with the travelling gear (171)
Take turns (173), cause paper-sheets rolling wheel (R1) rotary shaft insertion clutch gear (175), by the 2nd gear (173) and clutch
Connection gear (174) that device gear (175) is attached, clutch (176).
Here, the rotary speed of platen roller (R2) is compared to paper-sheets rolling wheel (R1) faster.
The clutch gear (175) is connected to the travelling gear (171), in side formed with the 1st raised (175a).
Also, the clutch (176) causes rotary shaft (178) insertion of the paper-sheets rolling wheel (R1), and it is fixed on rotation
Axle (178), formed with the 2nd raised (176a).The paper-sheets rolling wheel (R1) rotary shaft (178) formed with ladder rib (178a),
It is fixed with meeting in the inner peripheral surface and the shape of the ladder rib (178a) of the clutch (176).
Also, formed with more than one interposed clutch between the clutch gear (175) and clutch (176)
(177)。
The both sides of interposed clutch (177) are respectively formed with the 3rd raised (177a) and the 4th raised (177b), and the described 3rd is convex
Play (177a) to engage with the described 1st raised (175a), the described 4th raised (177b) engages with the described 2nd raised (176a).
By forming described above, the revolving force of motor (M) can pass through travelling gear (171) clutch gear
(175) rotate.
Also, when clutch gear (175) rotates, the 1st raised (175a) engages with the 3rd raised (177a) so that in
Between clutch (177) rotate, by means of the rotation of interposed clutch (177), the 4th raised (177b) nibbles with the 2nd projection (176a)
Close so that clutch (176) rotates.Finally, because clutch (176) is fixed on the rotary shaft (178) of paper-sheets rolling wheel, and can make
Obtain paper-sheets rolling wheel (R1) rotation.
Also, the platen roller (R2) especially, passes through paper-sheets rolling wheel so that speed rotates faster compared to paper-sheets rolling wheel (R1)
(R1) paper (P) is supplied forwards, when the front end of paper is articulated in platen roller (R2), paper-sheets rolling wheel (R1) and platen roller
(R2) link, and paper-sheets rolling wheel (R1) is rotated with platen roller (R2) same speed.
That is, now by the 2nd power transmission section transmit slower revolving force can not paper-sheets rolling wheel (R1) continue to rotate,
Paper-sheets rolling wheel (R1) and the rotation of platen roller (R2) link.
Illustrate this process in detail below, paper-sheets rolling wheel (R1) and paper link and with platen roller (R2) same speed
During rotation, the clutch (176) for being incorporated into the rotary shaft (178) of paper-sheets rolling wheel quickly rotates compared to interposed clutch (177).
That is, the 2nd raised (176a) quickly rotates compared to the 4th raised (177b), therefore, the 4th raised (177b) can not promote again so that
2nd raised (176a) rotation.
When this state continues and causes that clutch (176) rotates one time compared to interposed clutch (177) more, on the contrary, the 2nd
Raised (176a) promotes the 4th raised (177b) to be rotated.In this condition, the 1st raised (175a) is prior to the 3rd raised (177a)
Rotation, therefore, clutch gear (175) can not cause interposed clutch (177) rotation again.That is, turn into not by clutch
Gear (175) rotates, but the state for linking with platen roller (R2) and rotating at faster speed.
If the length of paper is shorter, and when paper-sheets rolling wheel (R1) and the shorter section of platen roller (R2) linkage, can remove
Interposed clutch (177), and it is only formed with clutch gear (175) and clutch (176).If the on the contrary, length of paper
Longer, paper-sheets rolling wheel (R1) and the section that platen roller (R2) links are longer, therefore, be formed with more than two interposed clutch
(177)。
I.e., with the length of paper accordingly, in being formed without between clutch gear (175) and clutch (176)
Between clutch (177), it is different according to the length of paper or formed with more than 2.
That is, the present invention formed with interposed clutch by enabling to yardage fully to grow.
Also, it was the rotation for the revolving force platen roller (R2) that motor (M) occurs by the 1st power transmission section in the past
Axle rotates.Also the revolving force for having the opposite side for the rotary shaft for causing platen roller (R2) slows down and causes paper-sheets rolling wheel (R1) rotation
Situation.I.e. so that the 1st power transmission section of platen roller (R2) rotation and the 2nd power transmission for causing paper-sheets rolling wheel (R1) rotation
Portion is formed at the respectively different side of substrate (110).As described above, the 1st power transmission section and the 2nd power transmission section are not formed
In the identical side of substrate (110), and when being formed at different one sides, formed in the rotary shaft itself of platen roller (R2) negative
Lotus, and platen roller (R2) is distorted.So as to, paper is kept straight on without normal direction positive direction, and on the skew with straight trip.But root
According to the present invention, the revolving force of paper-sheets rolling wheel (R1) and non-reception platen roller (R2), and directly receive travelling gear (171) i.e. motor
(M) revolving force and rotate.Thus, it is possible to so that platen roller (R2) is not distorted, paper is marched forward by pros.
Accordingly, because the 1st power transmission section and the 2nd power transmission section are jointly connected with travelling gear (171), described
