In this embodiment, there are three methods of magnet configuration (configuration of basic magnet), (configuration of adding auxiliary magnet), and (configuration of using repulsive force), and this embodiment is divided according to the configuration of the magnet. explain.

In addition, the same number is attached | subjected to the component (it applies to this Embodiment 2-10) which performs the same function as the component material used by this embodiment (1), and description is abbreviate | omitted as much as possible.
In the present embodiment, the shape of each magnet is circular or donut-shaped. However, since many modifications are possible, details will be described last with reference to the drawings.

Before starting the description of the present embodiment, the basic magnet configuration and the method of using the pressing device using the magnet as the stamping device will be described first, and the description of the detailed configuration diagram and the operation will be easy to understand later. To do. Needless to say, the pressing device can be applied to a device other than the stamping device, such as a die pressing, a punch, etc., simply as a spring.

FIG. 1 is a diagram showing the relative relationship between the first magnet 3 and the second magnet 6 with the magnetic poles oriented in the thickness direction of the magnet. In FIG. 1A, the first magnet 3 has a through hole 9 in the thickness direction, and the shape of the second magnet 6 is substantially similar to the through hole 9 in the thickness direction (not similar). Also works) and is a size that passes through. The second magnet 6 faces the first magnet 3 and the magnetic poles in opposite directions, and the surfaces of the magnets facing each other are the same poles (SS, NN), and the repulsive force (up and down arrow direction) is working.

However, in FIG. 1 (B), when it is further approached against the repulsive force and is brought closer to about 4 to 6 mm (which further varies depending on the strength of the magnetic force and the size), the through hole 9 of the first magnet 3 is reversed. The second magnet 6 is sucked by the attractive force.
At this time, due to the action of the magnetic pole on the opposite side through the through hole of the first magnet, the direction of the line of magnetic force flowing from the N pole of the second magnet 6 to the S pole of the second magnet 6 changes to the S pole of the first magnet 3. The direction of the line of magnetic force flowing from the north pole of the first magnet 3 to the south pole of the first magnet 3 changes to the south pole of the second magnet 6, and the first magnet 3 and the second magnet 6 are interlocked. It seems to construct one magnetic field line structure.
Therefore, the direction of the magnetic force reverses to the point where the balance of the magnetic force antagonizes, and the direction (up and down arrow direction) sucked into the through hole 9 of the first magnet 3.

In FIG. 1C, the second magnet 6 is sucked and held in the through hole 9 of the first magnet 3, but the magnetic pole surfaces of the first magnet 3 and the second magnet 6 are SN poles. Thus, the same is applied to the rear surface of the first magnet 3, and the portion is adsorbed in a substantially horizontal state while contacting a part thereof. Therefore, even if the second magnet 6 is moved by applying a predetermined range of force in the vertical direction (hereinafter referred to as “upward and backward”), the second magnet 6 is returned by the attractive force (hereinafter referred to as “return”) and held.

The thicknesses of the second magnet 6 and the first magnet 3 are the same, but it seems that the SN magnetic pole surface is closest and receives a strong magnetic effect. However, in order to achieve a good state when handled with a finger, the size of the first magnet 3 and the second magnet 6 and the strength of the magnetic force are adjusted.
Further, even when the second magnet 6 is thinner than the first magnet 3, the second magnet 6 can be used without any trouble, and the second magnet 6 is substantially in the center of the through hole 9 of the first magnet 3 while a part is in contact with the first magnet 3. It is held almost horizontally.

If the second magnet 6 is too thicker than the first magnet 3, the second magnet 6 is inclined in the through hole 9, and there may be a problem depending on the method of use.

Now, a method of using this basic magnet form as a pressing device will be described.
FIG. 2 shows a basic form of the pressing device according to the present invention. By providing the second magnet 6 on the pressing member 2 and fixing the first magnet 3 to the support base 4, the pressing member 2 is held in the air and functions as a pressing device. The second magnet 6 pierces the inside in the vertical direction from the operation end 1 side of the pressing moving member 2, and then is buried with the same member as the pressing moving member 2. Reference numeral 28 denotes a document (hereinafter, the pressed surface is referred to as a document).

When pressing, the side surface of the support base 4 is held with one hand and the installation surface 7 of the support base 4 is pressed against the document 28 and lightly fixed.
With the other hand, the operation end 1 of the pressing moving member 2 can be pushed down from directly above, and the document 28 can be pressed by the free end 5 of the pressing moving member 2. Further, it is possible to perform a series of operations by holding the vicinity of the operation end 1 of the pressing moving member 2 with only one hand. Reference numeral 8 denotes a hollow region.

Now, in the pressing device according to the present invention, the free end 5 of the pressing moving member 2 is engraved (hereinafter referred to as “engraved information such as letters, pictures, symbols, etc.)” to be used as a pressing device (hereinafter referred to as “ The “pressing device” functions as a “stamping device”.

The ink case 25, the ink and penetrating material 24, and the engraving surface sponge material 34 are used, and the other parts are the same as those of the lift type stamp of the present embodiment (3). Further, since the penetrating stamp is a spring type that does not use a magnet and is commercially available, a detailed description of the internal structure is omitted.
On the other hand, it goes without saying that the stamps and stamps of the other embodiments (the embodiments 1 to 3 and 5 to 10) can be made into a lift type stamp that penetrates the inside and makes it into a penetrating type.

(Configuration to add auxiliary magnet)
From this, the embodiment which adds the 3rd magnet 19 which is an auxiliary magnet to the structure of a basic magnet is described.
FIG. 16: is a perspective view of the seal set which sees through the magnet part of this embodiment (5). Except for the configuration of the magnet, the present embodiment (1) is the same as the seal stamp set, and other drawings are omitted.

The role of the third magnet 19 is used to assist the return force of the pressing moving member and extend the return distance.
When the seal 15 becomes heavy depending on the size or material, it is difficult to return. Therefore, the third magnet 19 is added to reduce the return distance to about 8 to 12 mm (further change depending on the strength and size of the magnet). In addition, when there is no locking structure such as a seal by increasing the restoring force, the risk of dropping at the time of pressing is reduced and the functionality is improved.

The direction of the magnetic pole of the third magnet 19 is directed opposite to the second magnet 6. When approaching the first magnet 3 by pushing down, a repulsive force is exerted under the influence of the magnetic pole (N) on the opposite side of the first magnet 3. When the second magnet 6 is arranged so that the repulsive force of the third magnet 19 works in the vicinity where the restoring force of the second magnet 6 becomes weak, it functions in conjunction with it.

The direction of the magnetic pole is opposite to that of the first magnet 3. When approaching the second magnet 6 by pushing down the seal 15, the return force can be assisted by the repulsive force under the influence of the opposite magnetic pole (S) through the through hole of the fourth magnet 20.
Moreover, although illustration is abbreviate | omitted, the three magnets in the form which removed the 3rd magnet 19 can also be used.

FIG. 19 is a side cross-sectional view of a lift type stamp in which the fourth magnet 20 is added to the support base 15 side in the present embodiment (8). Except for the configuration of the magnet, the present embodiment (3) is the same as the lift-type stamp, and other drawings are omitted.

(Configuration using repulsive force)
FIG. 20 is a perspective view of the seal set of this embodiment (9) using the repulsive force of the magnet and seeing through the magnet portion. Except for the configuration of the magnet, the present embodiment (1) is the same as the seal stamp, and other drawings are omitted. The magnetic pole of the second magnet 6 is directed in the same direction as the first magnet 3, and in this case, the second magnet 6 is not held by the first magnet 3. The balance is a balance between the repulsive force between the lower surface (N) of the first magnet 3 and the lower surface (N) of the second magnet 6 and the weight of the seal 15. If it is turned upside down, it may drop, but the function is the same, and if it is taken out, it can be used as an ordinary seal.

FIG. 21 is a side sectional view of the lift stamp according to the present embodiment (10). Except for the configuration of the magnet, the present embodiment (3) is the same as the lift-type stamp, and other drawings are omitted. The first magnet 3 is fixed to the inside of the support grip 22, and the support column 26 moves inside the first magnet 3. The second magnet 6 is substantially the same size as the first magnet 3, and the direction of the magnetic pole of the second magnet 6 is directed in the opposite direction to the first magnet 3. The second magnet 6 is not held by the first magnet 3. When the stamp set 24 floats due to the repulsive force but is locked by the shape of the pressing member 31 spread, or is stationary due to the balance with the weight of the stamp set 24, but pressed, the first magnet 3 and the second magnet Return with a repulsive force of 6 (SS).

Finally, the shape of the magnet will be described.
The first magnets 3 described so far are all formed in a circular shape (including a donut shape), but may be in other shapes as long as the effects of the present invention are achieved.
For example, in addition to the basic shape shown in FIG. 22A, a shape (c) in which a portion of a donut shape is cut out, a shape (f) in which the donut shape is divided in half, a rectangular shape or (B), (d), (e), and (g) enclosed in a rectangular shape are also included in the technical idea of the present invention.
Furthermore, as shown in (h), each of the magnets can be configured by a plurality (three in the example) of magnet pieces arranged in a direction crossing the advancing / retreating direction of the pressing moving member. At this time, it goes without saying that the magnet pieces have the same magnetic pole direction. It is not hindered to appropriately change the shape of the pressing moving member in accordance with the shape or arrangement of the magnet (magnet piece).
In addition, although illustration is abbreviate | omitted, even if it divides | segments and deform | transforms into a small piece similarly to the 1st magnet 3 also in the 2nd magnet 6, the 3rd magnet 19 and the 4th magnet 20 which are auxiliary magnets, it is mutually magnetic pole direction It goes without saying that the functions are the same if they are the same.
