Description

  The present invention relates to a low-pass filter cleaner for cleaning a low-pass filter in an interchangeable lens digital camera.

  In general, in interchangeable lens digital cameras such as digital SLR cameras, fine dust and dirt accumulate in the mirror box during lens replacement, and the dust and dust are rolled up by moving the mirror up and down during shooting. Adhering to the low-pass filter is a well-known phenomenon. The cleaning operation of the low-pass filter when dust or dirt adheres to the low-pass filter in this way is conventionally requested by the manufacturer's service center or the user receiving a training for cleaning performed by the manufacturer. (Applicant did not know prior art documents related to the present invention because it was devised based on publicly known public technology).

  However, in the above-described conventional cleaning method, it is necessary to request a maker's service center or receive a maker's training, so that the cleaning work takes much time and effort.

  The present invention has been made to solve the above-described problems, and provides a low-pass filter cleaner that allows the user to easily clean the low-pass filter and reduce the time and effort required for the cleaning work. It is intended to do.

  To achieve the above object, the present invention is a low-pass filter cleaner for cleaning a low-pass filter in an interchangeable lens digital camera, and a cleaning brush is attached to the tip so as to be in contact with the low-pass filter. An elongated intake cylinder, and an intake fan connected to the proximal end side of the intake cylinder so as to generate an air flow from the distal end side to the proximal end side in the intake cylinder. .

  The intake cylinder may be formed of a material that is likely to generate static electricity.

  The intake fan is housed in a case, and the case includes a cover member connected to a proximal end portion of the intake cylinder so as to cover the upstream side of the intake fan, and the cover member You may form with the material which is easy to generate | occur | produce.

  Further, a static electricity generating brush is provided on the outer peripheral portion of the intake fan so as to be in contact with the inner surface of the case, and is generated between the static electricity generating brush and the inner surface of the case as the intake fan rotates. It may be configured such that static electricity is generated in the case and the intake cylinder due to friction.

  According to the present invention, various excellent effects can be obtained, such as the user can easily remove the dust and dust around the low-pass filter and its surroundings, and the labor and time of the cleaning work can be reduced. Can do.

  Hereinafter, embodiments of the present invention will be described with reference to FIGS. Here, FIG. 1 is a cross-sectional view showing a low-pass filter cleaner according to the present embodiment, FIG. 2 is a plan view showing a suction fan of the low-pass filter cleaner, and FIG. 3 shows a suction fan of the low-pass filter cleaner. FIG. 4 is a plan view showing a tip member of a low-pass filter cleaner, and FIG. 5 is a perspective view showing a tip portion of the low-pass filter cleaner.

  A low-pass filter cleaner 1 according to the present embodiment includes a cylindrical box-shaped case 2 and a plurality of batteries 3 (in this case, six rechargeable dry batteries) housed on the base end side inside the case 2; Intake fan 4 and intake fan electric motor 5 housed on the front end side inside case 2, intake cylinder 6 connected to the front end side of intake fan 4, and tip member 7 attached to the front end of intake cylinder 6 The cap 8 is provided on the case 2 so as to accommodate the intake cylinder 6 and the tip member 7.

  The case 2 is formed of a material that easily generates static electricity, such as polycarbonate, and includes a case body 9 having a cylindrical shape with a proximal end closed, and a cover member 10 that is screwed into a distal end portion of the case body 9. It is configured. The cover member 10 is attached to the case body 9 so that about half of the threaded portion 11 formed on the outer periphery is exposed, and covers the upstream side of the intake fan 4. A power switch 12 is attached to the peripheral wall of the case body 9 in the vicinity of the electric motor 5, and an exhaust port 15 is provided on the downstream side of the intake fan 4.

  As well shown in FIGS. 2 and 3, the intake fan 4 has, for example, a fan diameter of about 5 cm and has a flat cylindrical outer shape. The static electricity generating brush 13 is attached in an oblique direction so as to be able to contact the inner surface of the case main body 9.

  The intake cylinder 6 is formed in an elongated cylindrical shape by a material that easily generates static electricity such as polycarbonate. In the present embodiment, for example, the length is about 5 cm, the outer diameter is about 9 mm, and the inner diameter is about 8 mm. The base end portion is set and attached to the cover member 10.

  The tip member 7 is fitted to the tip of the intake cylinder 6 and, as well shown in FIGS. 4 and 5, the tip of the tip member 7 is cleaned so as to be in contact with a low-pass filter (not shown) of the digital camera. A brush 14 is attached.

  The cap 8 is formed in a cylindrical shape whose front end side is closed in a hemispherical shape, and a base end portion is formed so as to be able to be screwed into the threaded portion 11 of the cover member 10, and is detachable from the case 2. It has become.

  Next, the operation of the low-pass filter cleaner 1 according to the present embodiment will be described.

  First, with the cap 8 removed from the case 2 and the power switch 12 turned on, the cleaning brush 14 of the tip member 7 is brought into contact with the low-pass filter, and fine dust and dirt adhering to the surface of the low-pass filter Remove. Then, these dusts and dirt are sucked into the intake cylinder 6 by the air flow from the front end side to the base end side generated in the intake cylinder 6 as the intake fan 4 rotates, and then are discharged from the exhaust port 15 to the outside. To be discharged.

  At this time, as the intake fan 4 rotates, static electricity is generated in the case body 9, the cover member 10, and the intake cylinder 6 due to friction generated between the static electricity generating brush 13 and the inner surface of the case body 9. Not only dust and dust adhering to the low-pass filter but also fine dust and dust around the low-pass filter can be adhered to the intake cylinder 6 and the cover member 10 and removed.

  As described above, according to the low-pass filter cleaner 1 according to the present embodiment, the user can easily remove the dust and dust around the low-pass filter and the surrounding area, thereby reducing the labor and time of the cleaning work. can do. Further, the low-pass filter cleaner 1 has a compact and lightweight structure, so it can always be carried to the photographing destination and has a cylindrical shape that is easy to operate with one hand. Can increase the sex.

  In the above-described embodiment, the electric motor 5 is driven by the battery 3. However, the electric motor 5 can be driven by a commercial power source by connecting a cable with an outlet.
