Description

[Detailed Description of the Invention] This invention relates to a stamp attachment/detachment structure that allows a stamp stand in a stamp printing device to be attached to a stamp mount very easily and accurately.

In general, conventional structures for easily attaching and detaching a stamp mount to and from a stamp mount attached to a stamp printing device such as a label printer include those shown in FIGS. 1 and 2, for example.

First, in the example shown in FIG. 1, 1 is a main shaft for attaching a stamp mount 2 to a stamp printing device (not shown), and 3 is a plate-shaped magnet stuck to the inside of the stamp mount.

Reference numeral 4 denotes a stamp stand with a stamp (not shown) to be printed on its underside, and 5 a holder made of a magnetic material such as a mild steel plate, which is fixed to the stamp stand. Further, the stamp mount 2 is formed in a U-shape as shown in FIG. 1, and the stamp holder 4 is fitted into the inside of this U-shape with almost no gap. Therefore, the stamp base 4 fitted into the stamp mount 2 is held by the holder 5 being attracted to the magnet 3, and the printing position will not shift due to repeated printing operations.

However, in order to fit the stamp holder 4 to the stamp mount 2, the holder 5 must be placed against the magnet 3.
The handle 5a, which is formed integrally with the holder 5, is held by hand and lifted in the direction of arrow A so that the respective surfaces are substantially parallel to each other. As shown in FIG.
After the stamp is removed from the stamp mount 2, it must be reattached.

Next, in the example shown in FIG. 2, 6 is a stamp mounting base, and 7 is a stamp base. 8, 8 are guide grooves provided inside the legs 6a, 6a of the stamp mount 6, and 9, 9 are bead portions provided on both sides of the stamp holder 7 in the longitudinal direction. The parts are formed so as to be slidable with each other and to fit together with almost no gap.

To fit the stamp holder 7 to the stamp holder 6, hold the handle 7a of the stamp holder 7 in the direction indicated by the arrow B so that both bead parts 9, 9 begin to engage with both guide grooves 8, 8 almost simultaneously. All you have to do is push it in the direction you want, but if you don't concentrate enough on this operation,
It is not easy to engage the bead portions and the guide grooves almost simultaneously.

If the stamp pad 7 is pushed in the direction of arrow B with either of the bead portions 9, 9 engaged with the guide groove 8 first, the stamp pad 7 will not slide smoothly into the guide groove 8. Instead, there are cases where they become stuck to each other and cannot move.

In the above-mentioned conventional example, it is difficult to quickly replace the stamp pad during printing because it takes care and effort to attach the stamp pad, and the handle of the stamp pad is attached to the front of the printing device (not shown). Because it was installed in the same direction, the label (not shown) was fed in the same direction as when it was being peeled off, which caused problems such as complicating the work.

This invention was made by focusing on such conventional problems, and a locating shaft is provided on either the stamp holder or the stamp mount, and the other is provided with a locating shaft.
A stamp stand attachment/detachment structure is provided with a guide groove that fits into the locating shaft and allows the stamp stand to rotate around the locating shaft, and a handle formed by bending one end of the stamp stand. This aims to solve the above problems.

This invention will be explained below based on the drawings.

3 to 5 are diagrams showing an embodiment of this invention. First, to explain the structure, 11 is a stamp mount, 12 is a magnet fixed to the stamp mount, 13 is a notch formed for positioning the stamp holder, which will be described later, and 14 is a stamp mount. 11
It is a locating axis installed upright at one end of the .

15 is a stamp stand; 16 is a holder for the stamp stand made of a magnetic material such as a mild steel plate; one end is provided with a guide groove 17 that engages with the locating shaft 14 of the stamp mount 11; A handle 18 is formed by bending the holder 16 at a substantially right angle. Numeral 19 is a protrusion that engages with the notch 13 of the stamp mount 11 to position the stamp holder 15. Reference numeral 20 denotes a stamp body having a printing part (not shown) on the lower surface in the figure, and is fixed to the holder 16.

Next, the action will be explained.

First, when attaching the stamp pad 15 to the stamp pad 11, the locate shaft 14 is brought into contact with the guide groove 17 of the stamp pad 15, and the holder 16 is
The upper surface is brought into sliding contact with the lower surface of the magnet 12, and then the fourth
As shown in the figure, place the stamp pad 15 on the locate axis 1.
5 in the direction of arrow C, the rotation stops at the position where the protrusion 19 engages with the notch 13 of the stamp mount 11. At this time, as shown by the solid line in FIG. 4, the holder 16 comes into full sliding contact with the magnet 12 and is held in the most strongly attracted state.

Note that at the time when the locate shaft 14 is brought into contact with the guide groove 17, a portion of the holder 16 is attached to the magnet 1.
2, and as the stamp pad 15 is rotated in the direction of arrow C, the sliding area with the magnet 12 increases and the attraction force increases, so the force that holds the stamp pad 15 upward during the installation process is Almost unnecessary.

Next, when removing the stamp pad 15 from the stamp mount 11, push the end of the handle 18 with your fingertip in the direction opposite to the arrow C.
rotates around the locate shaft 14, and can be easily removed from the stamp mount 11 when the attraction area of the holder 16 to the magnet 12 becomes small.

As explained above, according to this invention, in a stamp stand detachable structure in which a stamp stand is fitted and attached to a stamp mount, a locating shaft is provided on either the stamp stand or the stamp mount. , on the other hand, a guide groove that fits into the locating shaft and allows the stamp holder to rotate about the locating shaft; and a handle formed by bending one end of the stamp holder. Because it is a device, it can be attached to and removed from the stamp holder accurately and extremely easily by simply rotating the stamp holder around the locating axis, and the handle is formed in the horizontal direction of the stamp holder, making the work easier. In addition, as shown in FIG. 5, many types of stamp pads can be stored in a storage box or the like with their longitudinal end surfaces as the bottom surface, resulting in good storage efficiency.
