In a skin needle manufacturing apparatus, a material melted in a syringeis discharged from a fine holeof a pin memberand is caused to adhere to a base. A computercauses a drive mechanismto separate the pin memberfrom the base. Then, the materialhaving adhered to the pin memberand the baseis drawn out. A projection portionformed of a part of the material, which has adhered to the base, is formed into a skin needle. Consequently, a skin needle can relatively easily be manufactured without requiring excessive time, effort, and cost.

Skin needle manufacturing apparatus and skin needle manufacturing method

The disclosed herein is a novel and less expensive optical path switching apparatus for switching at least one input optical path selectively into at least one output optical path which comprises; switching means for switching the input optical path selectively into the output optical path which has at least one switching optical path to permit a light beam to pass thereon, inputting means for inputting at least one light beam to the switching means, and outputting means for outputting at least one light beam from the switching means, the switching means being essentially consisting of (i) a housing, (ii) at least one switching element having a first reflection surface to reflect the light beam inputted from each of input optical paths and a second reflection surface to reflect the light beam reflected from the first reflection surface toward the output optical path of the outputting means, and a reflection space formed between the first and second reflection surfaces of a switching element body, and (iii) at least one actuation element to actuate the optical path switching element for assuming two different positions including, a first position in which the input optical path of the inputting means is switched to the output optical path and a second position in which the input optical path is not switched to the output optical path of the outputting means.
