Description

  The present invention relates to a demonstration device for an optical lens.

  In general, optical lenses made of synthetic resin have the disadvantages that they are easily charged with static electricity and easily adhere to dust, but recently, various optical lenses made of synthetic resin with countermeasures against static electricity have been developed.

  As a demonstration method to show the superiority of such an optical lens with countermeasures against static electricity, conventionally, a granular material such as polystyrene foam is sprinkled on the surface of the optical lens, and the degree of adhesion of the granular material depends on the type of lens. It was common to compare how different the two are.

  However, in the above-described demonstration method, since the granular material is sprinkled on the optical lens, it is inevitable that the granular material is scattered around.

  The present invention has been made in view of the above-mentioned problems, and it is possible not only to compare at a glance how much the degree of adhesion of powder particles caused by static electricity varies depending on the type of optical lens, but also the powder particles. An object of the present invention is to provide an optical lens demonstration device that does not scatter the body.

  Note that the optical lens demonstration device described in the present application does not correspond to any of the above-described prior art optical lens demonstration devices, and as far as the applicant knows, there is no known example similar to the present application. At the time, there is no prior art document information to be disclosed.

  In order to solve the above problems, the present invention provides a lens holding portion capable of holding at least two optical lenses, a storage container for storing the optical lens and the lens holding portion, and a lens holding portion in the storage container. And a granular material supply means capable of supplying the granular material while circulating the granular material on the surface of the held optical lens, and the storage container stores the granular material supplied from the granular material supply means to the optical lens. The optical lens demonstration device is characterized by having a transparent portion that is formed in a sealed structure and can visually recognize the powder particles adhering to the optical lens surface from the outside.

  According to the present invention, the powder particles can be supplied to the surfaces of at least two optical lenses held by the lens holding portion, and the particles attached to the surface of the optical lenses through the transparent portion of the container are externally supplied. Since it can be visually recognized, it is possible to compare at a glance how much the degree of adhesion of powder particles caused by static electricity differs depending on the type of optical lens. As a result, it is possible to make a strong impression of the superiority of an optical lens that wants to appeal that there is little adhesion of powder particles.

  Moreover, since the storage container is formed in a sealed structure, the particles are not scattered.

  Here, the granular material supply means includes a blower fan provided inside the storage container and a motor for rotating the blower fan, and the blower fan is rotationally driven by the motor and stored in the storage container. It is preferable that the powdery granular material is sucked together with air and supplied to the optical lens by stirring and circulating in the container.

  In this way, the blower fan that is rotationally driven by the motor agitates and circulates the granular material stored in the storage container and supplies it to the optical lens, so that the granular material is circulated. The apparatus can be made simple and inexpensive because it is not necessary to provide a separate circulation path.

  The powder and granular material supply means includes a battery holder that houses a battery that supplies electricity to a motor that rotates the blower fan, and a switch that turns on and off the supply of electricity from the battery holder to the motor. It is preferable.

Demonstration is possible.

  Further, the blower fan is provided so as to blow upward at the bottom of the storage container, and the lens holding part is a lattice-like structure provided substantially horizontally above the granular material stored in the storage container. A lens receiving portion, and a suction cup portion provided on a side of the lens receiving portion and detachably supporting the optical lens receiving portion on the inner wall of the receiving container; and the lens holding portion is detached from the inner wall of the receiving container. Therefore, it is preferable that the state can be changed between a state in which the blower fan can be disposed on the bottom of the container from above and a state in which the blower fan is attached to the inner wall of the container and can hold the optical lens.

  In this way, the optical lens is held by the lattice-shaped lens receiving portion provided substantially horizontally above the granular material, and the blower fan is provided upward at the bottom of the storage container. The stored granular material can be uniformly and effectively supplied to the optical lens.

  In addition, since the suction cup portion is provided on the side of the lens receiving portion, it is possible to remove the lens holding portion from the inner wall of the storage container and place the blower fan on the bottom of the storage container from above. For this reason, the apparatus can be made simpler and less expensive because it is not necessary to process the bottom of the container.

You may comprise so that the made granular material may be stirred and circulated in a storage container and supplied to an optical lens.

  In this way, since it is possible to agitate and circulate the powder particles by the air blown into the container through the air blowing hose, there is no need to provide a blower fan or a battery holder in the container, The device can be made simpler and cheaper.

  In addition, the container includes an upper-opened bottomed container that can store powder particles at the bottom, a lid that covers and seals the opening of the container, and a lid that is detachably fixed to the container.

Moreover, since the container part is comprised with the transparent material, the granular material adhering to the optical lens surface can be visually recognized from a wider external range.

  Moreover, it is preferable that the said granular material contains the powder of a polystyrene foam.

  In this way, since the powder of polystyrene foam that easily adheres due to static electricity is contained in the powder, the degree of adhesion of the powder can be clearly seen.

  As described above, according to the present invention, it is possible not only to compare at a glance how much the degree of adhesion of particles caused by static electricity differs depending on the type of optical lens, but also to disperse particles. There is a remarkable effect that there is nothing.
