DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pen tip cleaning apparatus for cleaning a pen tip of an ink pen such as a hollow pen by ultrasonic waves, and a holder for the ink pen used therein.

[0002]

2. Description of the Related Art An ultrasonic cleaning apparatus for applying ultrasonic vibration to a cleaning liquid in a cleaning tank to ultrasonically clean articles in the cleaning tank has been known.

[0003]

Conventionally, there is known an ultrasonic cleaning apparatus for cleaning various articles. In any case, an ultrasonic cleaning apparatus is used for cleaning an article by putting the whole article in a cleaning liquid. No ultrasonic cleaning device has been developed in which only the tip of an ink pen is immersed in a cleaning liquid. SUMMARY OF THE INVENTION It is an object of the present invention to provide a pen-tip cleaning apparatus that can perform cleaning of a pen-tip by dipping only the pen-tip of an ink pen in a cleaning liquid.

[0004]

In order to achieve the above object, the present invention provides an ultrasonic cleaning apparatus having a cleaning tank (4) supported by a main body (2) and having a magnetostrictive vibrator (12) fixed to the bottom outer wall. In the apparatus, an ink pen (26) is received at an edge (4a) of an opening of the cleaning tank (4), and a nib (26a) of the ink pen (26) is placed in a cleaning liquid (14) in the cleaning tank (4). The ink pen (2
6) A writing tool holder (16) having a pen holding hole for locking the pen is placed thereon, and a height adjusting mechanism for adjusting the height of the pen holding hole is provided. The present invention also provides an edge (4) of an opening of a cleaning tank (4) of an ultrasonic cleaning device.
a mounting surface (20a) (34a) for mounting on a);
The ink pen (26) is received, and the nib (26a) of the ink pen (26) is moved to the cleaning liquid (1) in the cleaning tank (4).
4) A pen holding hole for locking the ink pen (26) at a position inside the ink pen is provided to constitute a holder used for a pen tip cleaning device of the ink pen.

[0005]

Embodiments of the present invention will be described below in detail with reference to the accompanying drawings. Reference numeral 2 denotes a box-shaped main body that can be placed on a flat surface such as a table, and a cleaning tank 4 is formed integrally with the main body. A magnetostrictive vibrator 12 composed of a ferrite core 6, a coil 8, and a permanent magnet 10 is attached to the bottom outer wall of the cleaning tank 4. The coil 8 is connected to an output terminal of a high-frequency oscillator (not shown) built in the main body 2. It is connected. The high-frequency oscillator is connected to a power supply via a time switch (not shown) attached to the main body 2. A cleaning liquid 14 is contained in the cleaning tank 4.

Reference numeral 16 denotes a writing instrument holder made of a transparent acrylic material, and includes a shaft 18, plate-like holding plates 20, 22 and a height adjusting tube 24. The holding plates 20 and 22 have a plurality of pen holding holes 28 and 30 for vertically inserting an ink pen 26 such as a commercially available hollow pen. The holding plate 22 is fixed to the lower end of the shaft 18. The tube 24 is slidably fitted to the shaft 18, and the center of the holding plate 20 is fixed to the tube 24.

A screw hole is formed in the tube 24, and a screw portion of a molding 32 is screwed into the screw hole, and the tube 24 is fixed to the shaft 18 by the molding 32. The tube 24 and the molding 32 constitute a height adjusting mechanism. The holding plates 20 and 22 are set horizontally at a predetermined interval from each other.
8 is set vertically. The holding plate 22 is set to a size suitable for being loosely fitted to the cleaning tank 4, and is mounted on the outer peripheral portion of the holding plate 20 for mounting on the edge 4 a of the opening of the cleaning tank 4. The surface 20a is formed.

Under the plurality of pen holding holes 28 of the holding plate 20, the pen holding holes 3 of the holding plate 22 are coaxially provided, respectively.
0 is arranged, and the holding hole 30 is set to a size capable of engaging a stepped surface or a tapered surface of the lower portion of the ink pen 26. A pair of upper and lower holding holes 28 and 30 on the same axis can hold one ink pen 26 vertically, and when the ink pen 26 is inserted into the pen holding holes 28 and 30, as shown in FIG. The upper large-diameter portion is slidably held in the pen holding hole 28 in the axial direction, and the lower small-diameter portion of the ink pen 26 is slidably held in the pen holding hole 30 in the axial direction. The lower step surface or the tapered surface is locked to a plate surface around the pen holding hole 30, and the ink pen 26 is locked at a fixed position with respect to the holding plate 22 by the pen holding hole 30. ing.

The pen holding holes 28, 30 of the holding plates 20, 22
Is inserted into the cleaning liquid 14, the pen tip 26a enters the cleaning liquid 14, and the pen tip 26a
The air intake groove (not shown) immediately above the cleaning liquid 14
Is set not to enter. This is because if the air intake groove near the pen tip of a commercially available hollow pen enters the cleaning liquid 14, the ink inside the hollow pen may flow out of the air intake groove. In the above-described configuration, by exciting the magnetostrictive vibrator 12 by the high-frequency oscillator, the nib 26a of the ink pen 26 held by the writing instrument holder 16 can be ultrasonically cleaned.

The height of the ink pen 26 held by the writing tool holder 16 is adjusted by loosening the molding 32 and
Is finely adjusted in the sliding direction with respect to the tube 24, and the height of the holding plate 22 is adjusted. In the present invention, the writing instrument holder is not particularly limited to the embodiment having the two-stage structure shown in FIG.
As shown in FIG. 7, a pen holding hole 36 into which the ink pen 26 formed of a hollow pen can be inserted into a single holding plate 34 having a mounting surface 34a that can be mounted on the edge 4a of the opening of the cleaning tank 4. May be provided. When the ink pen 26 is inserted into the pen holding hole 36, its collar is locked in the pen holding hole 36, and the ink pen 26 is arranged so that only the pen tip 26 a is immersed in the cleaning liquid 14. Pen holding holes 28, 30, 36 of the holding plates 20, 22, 34
May be able to change its size.

In this case, as shown in FIG.
An adjustment plate 40 having a hole 38 is slidably mounted in a horizontal direction below 0, 22, and 34, and the adjustment plate 40 is slid in the horizontal direction. The effective diameter of 30, 36 can be adjusted. Further, as shown in FIG. 5, the pen holding holes 28, 30, 3
6 is provided with a rubber plate 44 having a slit 42 formed radially below or above, which can be freely opened and closed, and holding holes 28, 30, 3.
The ink pen 26 may be held in the elastic member 6 by the elasticity of the rubber plate 44, and the size of the pen holding holes 28, 30, and 36 may be varied. In this embodiment, a hollow pen is used as an ink pen, but the present invention is not limited to the hollow pen.

[0012]

As described above, the present invention has an effect that the tip of the ink pen can be easily ultrasonically cleaned.
