The intensity of reflected light of alignment unit 38 under 35 pairs of current lights detects, to carry out calibrating (such as Fig. 6 automatically to ambient light
(A) shown in (a) in).Next in step S403, with the horizontal displacement of T-shirt pallets 31, vernier sensor 35 is right
Reflective light intensity on vernier guide rail 341 at diverse location is detected (shown in (b) in such as Fig. 6 (A)), also, is detected
Reflective light intensity by compared with the intensity of reflected light for the alignment unit 38 being detected to judge whether vernier 342 is detected
To (step S404), until ((c) in such as Fig. 6 (A) is shown) untill vernier 342 is detected.Perform step S402 to S404
Process it is corresponding with the state of the printing equipment as shown in (b) in Fig. 5.
It is detected in vernier 342 after (step S404's be), next, in step S405, control T-shirt supports
Disk 31 stops horizontal displacement to the left, and according to the location of vernier 342, controls T-shirt pallets 31 towards LED sensor 36
(to the right) horizontal displacement reaches LED sensor 36 to as the initial detecting position on the T-shirt32 surfaces indicated by vernier 342
Untill the underface of light, namely so that the vertical range between initial detecting position and the end face of printhead 37 can be passed by LED
Sensor 36 detects.Because now initial detecting position is located at the underface of the light of LED sensor 36 without stopping LED sensings
The light of device 36, then it is assumed that the vertical range between initial detecting position and the end face of printhead 37 be detected as be more than it is predetermined away from
From.The process for performing step S405 is corresponding with the state of the printing equipment as shown in (c) in Fig. 5.
Next, in step S406, control T-shirt pallets 31 shift up, until initial detecting position and printing
Untill vertical range between first 37 end face is detected as being less than predetermined distance by LED sensor 36 (in step S407 be),
That is, untill there is stop at initial detecting position to the light of LED sensor 36.Perform step S406 to S407 process with such as
The state of printing equipment shown in (d) in Fig. 5 is corresponding.
Once T-shirt pallets 31 are shifted up to the vertical range quilt between initial detecting position and the end face of printhead 37
Be detected as be less than it is predetermined apart from when, i.e. when there is stop at initial detecting position to the light of LED sensor 36, next, in step
In rapid S408, T-shirt pallets 31, which are just controlled to stop, to be shifted up, and towards the horizontal displacement of initialized location direction.Such as
Upper described, with one side horizontal displacement of T-shirt pallets 31, the detection light with LED sensor 36 on horizontal displacement direction has
