がきわめて簡単である。 Accordingly, in the present invention, in order to accurately measure the transmittance (actually reflectance) of light rays in the sebum part attached to the collecting surface, the collecting surface is colored dark to absorb as much of the transmitted light as possible. In addition, the light source uses red light from a light emitting diode, which is most suitable for transmitting through paper, and in order to make the light projected onto the collection surface and the light reflected from the collection surface as uniform as possible, a light emitting diode connected to the light emitting diode is used. A detector (optical sensor) is used in which an optical fiber is arranged in the center and a light receiving optical fiber connected to a phototransistor is arranged around the outer periphery. Furthermore, the collection device only needs to be inserted into the measurement section of the main body of the device, making the measurement operation extremely simple.
以下、本発明の実施例を図面に基づいて説明す

脂量を正確に測定するための重要な条件である。 As shown in FIGS. 2 to 4, the collector 1 includes a cylindrical holder 3 and a movable holder that is slidably fitted into the holder and has a rounded collection surface 5 at its tip. It consists of a rod 4, a push spring 6 that is installed inside the cylindrical holder 3 and urges the movable rod 4 to protrude freely, and a cylindrical cap 7 that is fitted onto the tip of the movable rod 4, and the collection surface 5 is dark. It is colored dark. Then, as shown in FIG.
As shown in the figure, collect sebum by pressing it against the skin area where you want to measure the amount of sebum. At that time, the movable rod 4 moves backward with respect to the holder 3, and its protruding step portion 4a
When the holder 3 is pressed until it comes into contact with the locking step 3a of the holder 3, the collection surface 5
can be pressed against the skin surface, and sebum can always be collected under the same conditions. This is an important condition for accurately measuring the amount of sebum.
脂吸収紙８には化粧用に市販されている脂取り

８はエーテル液につけて脱脂処理して使用すれば
より効果的である。 As the oil-absorbing paper 8, oil-absorbing paper commercially available for cosmetic use is used. Grease-absorbing paper is advantageous because it is inexpensive and does not cause chemical reactions with sebum or other secretions from the skin. Note that it is more effective to use the fat-absorbing paper 8 after soaking it in ether solution and degreasing it.
上述のようにして皮脂を採集し、少し時間をお

より皮脂量をデジタル表示する。 When the red light emitted by the light emitting diode 14 is projected onto the fat-absorbing paper 8 attached to the collection surface 5 through the light-emitting optical fiber 11, the red light is absorbed by the sebum 9 of the fat-absorbing paper 8. It is transmitted through the areas where the sebum 9 is attached and is absorbed by the dark-colored collection surface 5, but it is reflected at the areas where the sebum 9 is not attached and is transmitted to the phototransistor 15 through the light-receiving optical fiber 12, where it is converted into an electrical signal corresponding to the amount of light. converted. This electrical signal and an electrical signal corresponding to the amount of red light emitted by the light emitting diode 14 are sent to the light receiving circuit 16, and an electrical signal corresponding to the amount of sebum 9 is obtained based on the difference between the two electrical signals. Furthermore, this electrical signal is amplified by an amplifier circuit 17 and then sent to an A-D converter circuit 18.
The sebum amount is converted into a digital signal by the digital display 19, and the amount of sebum is digitally displayed.
