Formation method to scale (look and recognize labelling) 23 describes.Scale 23 forms in the following manner: to the predetermined position irradiated with pulse laser of the outer surface of the crust 27 that contains developer, utilize its this energy to make chromogenic reagent.
The pulse laser of irradiation can be enumerated for example carbon dioxide gas laser, He-Ne laser instrument, ruby laser, semiconductor laser, argon laser, excimer laser, YVO
4Laser instrument, YAG laser instrument etc.These laser powers are big and have an effect on surface that powerful fusing forms the resin material of crust 27.
Thermoplastic resin, heat-curing resin or rubber are being carried out under the situation of laser labelling, wavelength 1064nm, the 532nm of pulse laser 2,355nm all can carry out laser labelling.
Therefore, as pulsed laser light source 1, use and for example export that wavelength is the Nd:YVO of the pulse laser 2 of 1064nm
4Laser instrument is (hereinafter referred to as YVO
4Laser instrument).Pulsed laser light source 1 also can use for example exports that wavelength is the Nd:YAG laser instrument (hereinafter referred to as the YAG laser instrument) of the pulse laser 2 of 1064nm.These YAG laser instrument and YVO
4Laser instrument is changed the pulse laser 2 that exportable wavelength is 355nm, 532nm by half-wavelength.
Thermoplastic resin, heat-curing resin, thermoplastic elastic body are being carried out under the situation of laser labelling, all can carry out laser labelling from wavelength 1064nm, 532nm, the 355nm of the pulse laser 2 of pulsed laser light source 1 output.

Below, the laser labelling that uses laser marking device is described.
9 pairs of controllers 8 are set flag condition from the configuration part.About flag condition, for example in each following scope, set flag condition: the spot diameter r of pulse laser 2 be 5~100 μ m, pulse laser 2 hachure at interval h be that the Q-switch frequency Qf of 1~80 μ m, pulse laser 2 is that the scanning speed Sp of 0.1~100kHz, pulse laser 2 is 1~3000mm/sec.
The special flag condition of setting following degree: the spot diameter r of pulse laser 2 is that 40 μ m are following, the hachure of pulse laser 2 at interval h be that the Q-switch frequency Qf of 30 μ m, pulse laser 2 is that the scanning speed Sp of 30kHz, pulse laser 2 is 2~3000mm/sec.
Thus, the pulse laser of exporting from pulsed laser light source 12 scans along Y direction by Y-axis scanning device 6, and scans along X-direction by X-axis scanning device 5, and incides f θ lens 7.The pulse laser 2 that incides f θ lens 7 is as putting photoscanning on the surface of endoscope 10.The spot diameter r of the pulse laser 2 of this moment assembles by f θ lens 7, thereby forms 5~100 μ m, forms especially below the 40 μ m.
When pulse laser 2 was radiated on the surface of the crust that will form scale 23 27 of endoscope 10, crust 27 colors became white color system.Pulse laser 2 scans on the XY direction of principal axis by each pulse.Like this, the part color of the crust 27 of irradiated with pulse laser 2 becomes white color system by scanning.
That is, before irradiated with pulse laser 2, the color of the outer surface of crust 27 is black.With pulse laser 2 irradiation during to the outer surface of crust 27, crust 27 contained carbon blacks absorb pulse laser 2, are present in the carbon gasification of this illuminated portion.Disappear or tail off at the black content in this stage.
The resinous principle of crust 27 absorbs pulse laser 2 and converts light to heat.The heat that produce this moment makes the macromolecule of thermoplastic resin decompose concurrent bubble.Thus, since different in the part of foaming with the part refractive index that does not have irradiated with pulse laser 2, so do not become black.But diffuse-reflectance takes place in the surface of crust 27 of having shone the part of pulse laser 2, and whitening.Its result is for having formed scale 23 in endoscope 10.
In for example insertion section of endoscope 10 flexible pipe 11, operating portion 12, adapter portion 13, except the display part 21 that is constituted by scale 23 and numerical value 24, also have each display part 22,17~19,20 by laser labelling.Each display part 22,17~19,20 also is to make the part color of crust 27 become white color system by crust 27 irradiated with pulse laser 2 to endoscope 10 to form.
