Description

  The present invention relates to an enlargement imaging apparatus for magnifying and observing the surface of an object to be observed, and in particular, a beauty staff who sells cosmetics determines the optimal cosmetics, champagne, etc. according to the condition of the customer's skin and scalp. This is suitable for magnifying and observing the customer's skin, scalp, etc.

Cosmetics are applied directly to the skin to make the skin appear white or rough skin becomes smoother, so each cosmetic manufacturer offers many types of cosmetics according to the skin quality. I sell it.
Therefore, while consumers can select cosmetics that suit their skin quality from many types, they are often unable to select truly suitable cosmetics because they do not know their skin quality.

This is the same for beauty staff who sell cosmetics, and if you know exactly the skin quality of your customers, you can advise on cosmetics and skin care that are appropriate for that skin quality. The actual situation is that he advises cosmetics that will fit the customer's skin quality based on the experience and intuition he has cultivated.
Therefore, recently, various diagnostic devices have been introduced to promote the sales of cosmetics, and each company has been working hard to provide the best cosmetics for customers' skin quality.

A magnified imaging device for observing the skin is also used as one of such diagnostic devices, but there is a demand for observing by changing the magnification factor depending on the observation target.
For example, when observing the fineness of the texture formed by fine twills that run diagonally in the vertical and horizontal directions, it is preferable to image a range of 1 to 2 cm in diameter with a relatively low imaging magnification of about 20 times. When observing each of the textures (textures), it is preferable to image a very limited area having a diameter of 1 to 2 mm with a high imaging magnification of about 120 times.

However, in order to change the imaging magnification, it is troublesome to change the lens or change the illumination light intensity by operating the switch, so the applicant is troublesome to change the lens every time the magnification is changed. In addition, there has been proposed a trouble-free enlargement imaging apparatus that performs a switch operation for switching the intensity of illumination light each time the magnification is changed.
Japanese Patent No. 3626415

  According to this enlargement imaging apparatus, the imaging magnification can be switched by moving the position of the bifocal lens in the optical axis direction, and the low magnification imaging illumination and the high magnification imaging illumination are automatically switched according to the position of the lens. As a result, no switch operation is required for lens replacement or illumination light switching.

However, since imaging is performed through one observation hole during both low-magnification imaging and high-magnification imaging, the observation hole must be made relatively large with a diameter of 15 mm in accordance with a low-magnification imaging area.
Therefore, when this is pressed against the skin, the skin swells in the observation hole due to its elasticity, and when imaging at a low magnification with a deep depth of field, yet when imaging at a high magnification with a shallow depth of field Caused the problem of focusing or shifting depending on how the skin swelled.

  For this reason, during high-magnification imaging, it is necessary to cover the cap with a small-diameter observation hole to prevent the skin from rising, and there is no need to replace the lens. There is also the trouble of having to prepare a spare cap.

  Therefore, the present invention provides a technical problem that when changing the magnification, it is not necessary to replace the lens, and it is not necessary to attach and detach the cap, and it is possible to capture a focused image at both low magnification and high magnification. It is said.

  In order to achieve this object, the present invention provides an image of an observation object incident from the observation hole by bringing the observation hole of the dome-shaped imaging head formed on the imaging optical axis into contact with the surface of the observation object. In the magnifying image pickup apparatus including a magnification adjusting mechanism for changing the magnification of the image pickup device, an image pickup device for picking up an enlarged image, and an illumination system for irradiating the observation object with illumination light from the inside of the image pickup head. The magnification adjusting mechanism is configured such that the magnifying lens is attached to a rotating body whose axis is a rotation axis that is orthogonal to the imaging optical axis, and the magnifying lens rotates on the imaging optical axis by rotating the rotating substrate by 180 °. The observation hole for high-magnification imaging, which is formed so as to move to the high-magnification imaging position and has a smaller aperture than the observation hole formed in the imaging head, moves the observation hole of the imaging head during high-magnification imaging in conjunction with the rotation of the rotating body. Advancing and retracting to cover It is characterized in that it is formed.

According to the magnifying image pickup apparatus of the present invention, the magnifying lens is positioned at the high magnification image pickup position and the low magnification image pickup position by rotating the rotating body by 180 °, so that the optical magnification can be switched between the low magnification and the high magnification. .
In addition, when the rotating body is rotated, the observation aperture for high-magnification imaging with a small aperture advances on the optical axis at the time of high-magnification imaging, so the object to be observed is imaged through the observation aperture for high-magnification imaging. Since the observation hole for high-magnification imaging retracts during low-magnification imaging, the object to be observed can be imaged through the large-diameter observation hole formed in the imaging head.
Therefore, by simply rotating the rotating body, the lens position can be moved and the optical magnification can be switched. At the same time, the aperture of the observation hole can be adjusted according to the optical magnification. There is no need to perform special operations.

  In addition, when it is necessary to change the intensity of the illumination light, as described in claim 4, the low magnification imaging that irradiates the illumination light from the periphery of the magnifying lens positioned at the low magnification imaging position toward the object to be observed. When the optical magnification is changed by providing a high magnification imaging illumination system that emits brighter light than the low magnification imaging illumination system from the periphery of the magnifying lens positioned at the high magnification imaging position toward the object to be observed In conjunction with this, the low-magnification imaging illumination and the high-magnification imaging illumination may be switched on and turned on.

  In this example, when changing the magnification, in addition to replacing the lens, it is not necessary to attach and detach the cap, and in order to achieve the purpose of capturing a focused image at both low and high magnifications. Further, the magnifying lens is mounted on a rotating body whose axis of rotation is orthogonal to the imaging optical axis, and the magnifying lens is moved to the low magnification imaging position and the high magnification imaging position by rotating the rotating body by 180 °. The observation hole for high-magnification imaging having a smaller diameter than the observation hole formed in the imaging head is moved back and forth so as to cover the observation hole for low-magnification imaging during high-magnification imaging in conjunction with the rotating body.
