[0001] MICROSCOPE FOR MOBILE TERMINAL [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a microscope for a mobile terminal, and more particularly, to a microscope for a mobile terminal which is detachably attached to a mobile terminal and is capable of observing the sample through the mobile terminal.

In general, a microscope is a device that magnifies and observes microscopic objects and microorganisms, which are difficult to identify, from several tens to hundreds of times. Such a microscope includes a lens and a sample plate. Thus, the observer can enlarge and observe the sample placed on the sample plate through the lens.

In recent years, research and development of a portable microscope capable of observing a sample using a camera and a light source of a mobile terminal to improve the portability and mobility of the microscope have been continued.

A conventional portable microscope is disclosed in Korean Patent Laid-Open Publication No. 2007-0033613 (Portable Digital Microscope for Mobile Phones, 2007.03.27). The patent discloses a lens system mounted on a barrel, an image processing unit disposed on the upper side of the lens system for transmitting an image of the sample to a mobile phone, and an illumination unit disposed below the lens system for illuminating light toward the sample. The present invention is characterized in that a digital image of a sample is transmitted to a mobile phone.

However, in the present invention, since the image of the sample is converted into a digital image and is provided to a mobile phone, it is difficult to produce a microscope, and the manufacturing cost of the microscope increases. In addition, since the light provided from the illumination means toward the sample is provided only in the upper direction of the sample, the present invention has a problem in that it is difficult to observe the sample depending on the type and transparency of the sample.
