DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a key top printing device which is a key body inserted into a keyboard, and more particularly to a key top printing device for printing a display such as characters on the surface or side surface of the key top.

[0002]

2. Description of the Related Art Conventionally, as shown in FIG.
Jig 3 for holding and positioning key top 1
A steel plate 6 holding ink 7 attached to a destination where the pad printing machine 5 has been moved as a part of the pad printing machine 5; and a transfer plate attached to the tip of the soft pad printing machine 5. And a transfer body 8 made of soft rubber of a body holder 9. The printing operation of the pad printing machine 5 is as follows.
As shown in FIG. 3B, the ink 7 contained in the steel plate 6 attached to the pad printing machine 5 is fixed to the set jig 3 so that the transfer surface 10 of the key top 1 is horizontal. It is picked up and stamp-transferred to the corresponding transfer surface 10 of the key top 1. Also, the set jig is similarly moved with respect to the top surface transfer surface 11 and the other side transfer surface.

[0003]

In this conventional key-top printing apparatus, there is a setting condition of a set jig and a condition of a tilt angle at which the pad printing machine 5 can print, so that the tilt angle is about 12 degrees or more from the horizontal plane. Printing the surface is impossible,
Batch printing of the side surfaces of a plurality of key tops cannot be performed in a state in which the key tops are fixed to the keyboard, and it is necessary to print the key tops one by one on a jig. Furthermore, since key tops are printed individually,
There was a possibility that a keytop with a display other than the specified one was incorrectly inserted.

[0004]

According to the present invention, there is provided a key top printing apparatus comprising a keyboard and a key inserted into the keyboard.
The board body (hereinafter referred to as key top) is correctly
On the other hand, the key is arranged in parallel in a vertical M (M is an integer) column.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be described with reference to the drawings. FIG. 1 is an explanatory view showing the state of one embodiment of the present invention, and FIG.
FIG. 2 is a partially enlarged view of the embodiment of FIG. In FIG. 1, a keyboard 2 in which a key top 1 is inserted, a set jig 3 for holding the keyboard in an inclined state, a positioning mask 4 for positioning the key top 1, and a pad printing machine 5 similar to the conventional example are attached. Steel plate 6 engraved with characters and symbols
And a transfer body 8 holding the transfer ink corresponding to the transfer surface shape of the key top 1,
A transfer body holder 9 having a function of moving the transfer body 8 up and down. In the embodiment of FIG.
The key top 1 is mounted on a set jig 3 in a state of being inserted into the keyboard 2, and the plurality of key tops are pressed on the upper surface of the keyboard 2 by a steel-like positioning mask 4 to position the key top 1. Next, putt press 5
Picks up the ink 7 of the steel plate 6 by the transfer body 8, moves the transfer body holder 9 onto the keyboard 2, and performs printing in accordance with the transfer position. Since the plurality of key tops have different heights, the transfer body 8 is lowered stepwise in accordance with the respective key tops so as to perform imprint transfer. In addition, as shown in FIG. 2, the shape of the transfer body 8 is a curved surface of R4.5 m / m and 3 m / m.
, And can be set to be about 4 degrees wider than the shape of the key top 1, so that the key top 1 can be completely adhered to the transfer surface 10. Further, since the set jig 3 can move to the transfer surface 11 to an inclination of about 12 degrees or more from the horizontal plane, batch printing can also be performed on the transfer surface 11 together with the opening of about 4 degrees due to the curvature of the transfer body 8. It is possible.

In the embodiment shown in FIG. 1, the case where one side transfer surface 10 is transferred is exemplified.
According to the setting, the other three side surfaces including the top surface transfer surface 11 can also be transferred.

[0007]

As described above, the key top printing apparatus according to the present invention enables simultaneous printing of the top and side surfaces while the key top is inserted into the keyboard.
It is possible to make a line with top surface printing, and the number of printing steps can be reduced. Also, by performing batch printing with the key top set on the keyboard, there is also an effect that there is no risk of erroneous printing and the number of inspection steps is reduced.
