Description

Technical field to which the invention belongs

The present invention relates to a memory card terminal cleaner.

Memory cards developed for PC notebook computers are currently digital cameras, digital audio players, mobile phones, and PlayStation. It is used as a portable storage medium. Memory cards are used by being inserted into dedicated slots provided in the various devices described above, but depending on the frequency of use, there is a problem with the terminal receptacle that joins the terminals of the memory card provided inside the slot (dirt due to dust etc.). There is a cleaning card of the same size as the memory card to prevent.

Problems to be solved by the invention

However, as described above, it is considered that not only the terminal receiver inside the slot is dirty but also the terminal of the memory card is dirty. To always use various devices in the best condition, the terminal holder of the slot is It is desirable to clean the terminals regularly, but the memory card terminals are formed to be recessed from the molded part of the main body, and the lengths and positions of some arranged terminals are not necessarily constant. There is currently no cleaner that can clean all terminals equally.

Means to solve the problem

In the present invention, optimal brushes for cleaning memory card terminals having different external shapes, terminal sizes, and terminal shapes are arranged radially around an axis, and the brush is rotated on one of the axes. There is a knob. The brush is fixed to the housing at one end or both ends of the shaft, and is configured to be able to rotate back and forth by a knob provided on the shaft. In order to appropriately cope with the difference in terminal size and terminal shape and enhance the cleaning effect, it is effective to change the length of the brush. For this purpose, an equal-length brush is formed eccentrically from the center of the mounting shaft so that the length of the brush extending radially from the shaft changes.
By doing so, when the shaft on which the brush is formed is rotated, cleaning is performed while the length of the brush in contact with the memory card is changed to a continuous floor with rotation. In order to obtain the same cleaning effect, in addition to the above-mentioned brushes, a type having long and short brushes of the same length on the same circumference and irregular long and short brushes on the same circumference were provided. A type or the like may be used.

The housing is provided with an insertion hole on the front surface where a memory card with different external shape (thickness, width) can be inserted, a bottom surface that is flush with the bottom of the insertion hole is provided in the housing, and the memory card is inserted into the bottom surface. In this case, a convex abutment is provided on the bottom surface of the housing so that the terminals of the memory card are set directly under the center of the radially arranged brushes to be cleaned, and one side surface extends from the insertion hole to the convex abutment. It is formed with an undercut. On the other hand, by providing a slide knob whose side is undercut to the same size so as to be symmetric to the insertion hole formed with the above-mentioned undercut, the terminal of the memory card that has a different external shape (thickness, width) can be securely placed at the cleaning position. It is configured so that it can be set and locked.

A groove corresponding to the length of the radially arranged brush is provided in the housing, and an absorbent material (sea surface, sponge, nonwoven fabric, etc.) for sucking a cleaning liquid is provided in the groove so that the absorbent material and the brush are in contact with each other. It is configured so that wet cleaning can be performed by moistening the brush by injecting a cleaning liquid into the absorbent. The absorbent material is made of a material that can effectively remove dust, dust and the like adhering to the brush during both dry and wet use.

Memory cards that are difficult to remove after cleaning the memory card terminal can be easily removed by unlocking the slide knob and then rotating the rotary knob of the brush in the opposite direction.

Embodiments and embodiments of the invention

The configuration of the present invention will be described with reference to FIGS.
The housing 1 has notches 2a and 2b for setting cleaning brushes 11 which are eccentric to the central axis 9 and arranged radially, an insertion hole 3 in which a side wall undercut surface 6 for inserting a memory card 17 is formed, and a memory card 17 A bottom surface portion 5 that contacts the bottom surface and an abutting portion 4 are formed, a slide knob 7 in which a side wall undercut surface 8 is formed is attached to the insertion hole 3, and is eccentrically arranged on a central shaft 9 engaged with a knob 10 and radially arranged. The brush 18 is formed and set in the notches 2a and 2b of the housing 1.

The lid 12 is provided with a bottle mounting box 13 and a frame 14, and an absorbent material 15 is attached to the frame 14. The lid 12 is combined with the housing 1 and a cleaning liquid bottle 16 is set in a bottle mounting box 13. In addition, the cleaning brush has a central shaft 9 other than the brush, a brush 18 having the same length on the same circumference, a brush 19 having a length on the same circumference, and a long and short brush which is not the same length on the same circumference. It is also possible to use a brush 20 or the like that is provided irregularly upward.

An embodiment of the present invention will be described with reference to FIGS.
Insert the memory card 17 on the bottom surface 5 of the insertion hole 3 provided in the housing 1 until it hits the abutting portion 4, and then operate the slide knob 7 to lock and rotate the knob 10 to clean the terminal 21 of the memory card 17. To do.

The invention's effect

Since the isometric brushes are radially decentered from the center of the mounting shaft, the length of the brush is theoretically the same as changing the length of the brush. The height of the brush changes to an unrestricted floor, so you can easily and reliably clean the tip of the brush everywhere on any type or shape of memory card.

Since both dry and wet cleaning is possible, it is possible to deal with dirt and is highly effective.
