However, in the conventional book surface cleaning apparatus, it is necessary to specially provide a precise positioning device and a take-out device because the book is easily damaged, and the mechanism is generally complicated. Tend to. Further, in a cleaning device of a type in which a book is set horizontally, cleaning is performed by vibration while the book is placed on a horizontal table, but since the surface pressure is different between the upper surface and the lower surface of the book, the upper and lower surfaces of the book are And the finished condition is different, and cleaning unevenness is likely to occur. To avoid this, the book can be turned upside down and cleaned again, but in such a case, the work becomes twice and the work efficiency is reduced by half. In a one-step book cleaning device,
In general, there is a problem in that it is difficult to precisely and reliably remove dirt from a book. The present invention has been made in view of the above problems, and an object of the present invention is to provide a simple book surface cleaning device that can automatically and finely remove dirt on a book surface and has high cleaning efficiency.

[0004]

SUMMARY OF THE INVENTION Accordingly, the present invention is a book surface cleaning apparatus for removing dirt from the book surface by vibrating the book while sandwiching the book between a pair of diaphragms to which a wiping member is attached. A pair of cleaning units having the diaphragm are provided so as to be able to approach and separate from each other, a resonance piece is fixed to an elastic body connected to the diaphragm, and the resonance piece is vibrated by energizing an electromagnet. Features.

[0005] Items to be cleaned are CDs in addition to books.
And a storage case for a magnetic recording medium, and the dirt on the surface thereof is removed using minute vibration. The vibrating means for generating vibration on the diaphragm uses an electromagnet and a resonance piece facing the electromagnet, and the resonance piece is connected to an elastic body coupled to the diaphragm. On the surface of the diaphragm, a wiping member that contacts the book is fixed, and this wiping member may be directly attached to the diaphragm, or indirectly attached via a fastening means such as a hook-and-loop fastener.

In 9, a towel 20 for applying a detergent and wiping off stains on the book 3 is detachably attached and can be replaced. Both ends of the towel 20 are fixed to the upper surface ends of the cleaning units 4 and 5 with fixing fittings 21.

Therefore, the towel 2 is attached to the hook-and-loop fastener 19.
The vibrations generated on the diaphragms 16 and 17 are directly transmitted to the towel 20, and the dirt on the book 3 is wiped off by the vibration friction of the towel 20 because the zeros are integrally polymerized and adhered. In this embodiment, one towel 20 is suspended between the left and right diaphragms 16 and 17 in a concave shape (U-shape), and
Although the both ends of 0 are fixed by the fixing bracket 21,
The two towels 20 may be separately fixed to the left and right diaphragms 16, 17, respectively.

Next, the structure of the vibrating section of the cleaning unit 5 will be described. Since the vibrating section of the cleaning unit 4 has the same structure, the description thereof will be omitted. As shown in FIGS. 3 and 4, a vibrating body base 22 is provided below the cleaning unit 5, and three fixing portions 2 are provided on the upper surface of the vibrating body base 22.
3, 24 and 25 are provided at intervals in the width direction. Each of the fixing portions 23 and 25 has a leaf spring (elastic body) 2.
The lower ends of the plate springs 6 and 27 are attached, and the upper ends of the leaf springs 26 and 27 are fixed to the diaphragm 17 at angles 28 having an L-shaped cross section.
29 are connected by bolts. An iron resonance piece 30 is fixed to the right surface of the angle 28.

An electromagnet 32 is fixed to the upright portion 31 connected to the fixed portion 24 in the vicinity of the resonance piece 30, and the electromagnet 32 includes a laminated core and a wound coil. An oscillating current is supplied to the electromagnet 32 via a power switch (not shown). The power switch is provided in a control box (not shown) separately installed outside the cleaning unit 5. The control box is provided with a dial for setting and changing the output and frequency of the oscillating current. Therefore, when the power switch is turned on, an oscillating current is supplied to the electromagnet 32, whereby the resonance piece 30 vibrates and minute vibration is transmitted to the diaphragms 16 and 17 via the leaf springs 26 and 27. It is supposed to be.

Next, a procedure for using the book surface cleaning device will be described. First, one towel 20 is hung in a concave shape between the left and right cleaning units 4 and 5, and
The towel 20 is overlaid on the hook-and-loop fastener 19 on the top 7 and brought into close contact therewith. At this time, both ends of the towel 20 are firmly fixed with the fixing brackets 21 so that wrinkles do not occur on the towel 20. Next, an appropriate amount of detergent is spray-applied to the surface of the towel 20 in close contact with the hook-and-loop fastener 19 by spraying. After the application, the power switch is turned on, and an oscillating current is supplied to the electromagnet 32. Then, the resonance piece 30 vibrates according to the frequency of the oscillating current, and the vibrating plates 16 and 17 vibrate via the leaf springs 26 and 27. At this time, depending on the size of the book 3, the degree of dirt, and the like, the vibration width of the diaphragms 16 and 17 becomes an appropriate amount.
The output of the vibration is appropriately adjusted by the dial of the control box.

Next, the book 3 is inserted between the left and right diaphragms 16 and 17, and the book 3 is set on the concave lower bottom portion of the towel 20 so that the spine of the book 3 faces downward.
Pull the operation handle 10 to the near side (the left side in FIG. 1). Then, the right cleaning unit 5 approaches the left cleaning unit 4, and the book 3 is lightly held between the left and right diaphragms 16 and 17. As a result, a small vibration is applied in a state where the towel 20 is in close contact with both surfaces of the book 3,
Wiping cleaning of the surface is started. In this case, towel 2
0 is integrally adhered to the hook-and-loop fastener 19 over the entire area, so that vibration from the diaphragms 16 and 17 is
0 is directly transmitted to the book 3 on the
0 effectively wipes it off.

After the book 3 has been cleaned for an appropriate period of time, the operating handle 10 is pulled further strongly to the front. Then, the oscillating frictional force of the diaphragm 17 against the book 3 increases, and the lower bottom tapered surface 18 causes the book 3 to largely move upward. Therefore, the book 3 can be taken out of the left and right cleaning units 4 and 5 by quickly grasping the upper part of the book 3 that has protruded from the cleaning units 4 and 5.

Thereafter, when the book 3 is taken out, the operation handle 10 is returned to the original position, the right cleaning unit 5 is moved away from the cleaning unit 4, and the degree of dirt of the book 3 is confirmed. If the degree of dirt removal of the book 3 is insufficient, the book 3 is inserted and set again between the left and right vibrating bodies 16 and 17, and the operation handle 10 is pulled toward the user.
The book 3 is wiped and cleaned as described above. At this time, if the amount of the detergent applied to the towel 20 is small, an appropriate amount of the detergent is replenished to the towel 20 by spraying.

Thus, the cleaning of the book 3 is completed. When another book 3 is to be subsequently cleaned, the book 3 may be inserted between the left and right diaphragms 16 and 17, and the wiping and cleaning with the towel 20 may be repeated according to the above-described procedure.
When the surface of the towel 20 becomes dirty due to long-term use, the dirty towel 20 is removed from the hook-and-loop fastener 19 and replaced with a new towel 20.

As described above, the book 3 is moved to the left and right vibrators 16,
17, the book 3 can be easily wiped only by an energizing operation. Also, the book 3 after wiping
Can be taken out simply by pulling the operation handle 10, and there is no need to specially install a book 3 take-out device. Further, since the vibrators 16 and 17 generate vibration using the electromagnet 32 and the leaf springs 26 and 27,
There are advantages such as a simple and compact structure, no consumables, few failures, and low noise.
