DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a jig in which a front end surface of a moving member which protrudes and retracts from a jig main body with respect to a work such as a work to be processed, a work to be transferred, and the like.

[0002]

2. Description of the Related Art In the manufacture and transportation of articles, various jigs are used as needed for workpieces in the manufacturing process or during transportation. For example, for a film-shaped work, a pin, which is a moving member, protrudes and retracts from the jig main body to carry or position, or the conveying member has irregularities, and any of the irregularities is determined by a jig. When it is necessary to perform correction, a correction member as a moving member is protruded and retracted from the jig body to cover the uneven portion so that even if there is an uneven portion, there is known a device that does not hinder work. .

In the following, for convenience of description of the present invention, attention will be given to an IC card transport jig used for various electronic devices.

[0004] An IC card is generally constructed by embedding an IC module in a plastic card base material.
On the front and back surfaces of the card, characters and graphics are printed.

[0005] In recent years, printing of IC cards has been performed by continuous printing. For example, as shown in FIG.
The C cards 1, 1 are mounted on a large-diameter printing roller R, and these are slidably contacted with the transfer rollers r, r to perform printing. As shown in FIG. 10, the print roller R is provided with jigs 2 and 2 for holding a work (IC card), which are jigs for a work (IC card).

The jig 2 for holding an IC card includes a jig main body 2a.
Of the jig body 2a is provided as a suction surface plate 2b, which is a contact surface plate for contacting and adsorbing an IC card. I have. That is, a large number of through holes 2c, 2c are formed in the suction face plate 2b, and air is sucked from the through holes 2c, 2c by driving a suction pump (not shown) to be supplied to the suction face plate 2b of the jig main body 2a. IC cards 1 and 1 to be sucked and held.

Since the IC cards 1 and 1 have the IC module embedded in the card base as described above, the card base has a recess 1a for embedding the IC module. This recess 1a for embedding is shown in FIG.
As shown in the figure, it is usually formed in two stages by providing a step portion,
The central portion is formed in the thinnest portion 1b. Further, there are two types of IC modules buried in the card base, eight terminals according to the ISO standard and six terminals according to the ISO standard. Therefore, in order to ensure that each IC module is embedded, the embedding recesses 1a are provided for the six terminals shown in FIG. 11 (2) and for the eight terminals shown in FIG. 11 (3). These recesses have the same depth but have slightly different shapes. That is, it is known that the entire position where the module including the embedding concave portion 1a and the thinnest portion 1b is embedded is different, and particularly, the shift t of the center position of the thinnest portion 1b is 0.25 mm according to the ISO standard. ing.

[0008]

When an IC card is held by an IC card holding jig and printing is performed, as shown in FIG.
When the front surface of the card 1 faces the suction face plate 2b of the jig main body 2a, the IC card 1 comes into contact with the suction face plate 2b and is sucked by the suction face plate 2b by the suction force from the through holes 2c. This causes a problem in the thinnest portion 1b of the embedding recess 1a. That is, as shown in FIG.
b is sucked toward the suction face plate 2b and curved. Then, on the back side of the IC card 1, the portion of the thinnest portion 1b is depressed, so that the sliding contact of the transfer roller is not sufficiently performed at the time of printing, which causes a problem that the print quality is deteriorated.

In this case, the through holes 2c, 2c are arranged so as not to correspond to the embedding recess 1a in consideration of the positions of the through holes 2c, 2c so that the thinnest portion 1b is not sucked toward the suction face plate 2b. It was found that the thinnest portion 1b was sucked toward the suction face plate 2b and bent to a greater or lesser degree due to leakage of the suction air.

When the front and back sides of the IC card are reversed, that is, when the back side of the IC card is attracted to the suction face plate, the above-described inconvenience does not occur. However, it is conceivable to separately attach an appropriate supplementary member to the corresponding location of the suction face plate, but it takes time and effort to attach and detach the supplementary member, and there remains uncertainty about the positional accuracy and height accuracy of the attachment. Furthermore, there is a problem in durability against continuous printing, which is not preferable.

The present invention has been made in view of the above circumstances, and in printing such an IC card having, for example, an IC module embedding recess as described above, avoids printing failure on the back surface of the embedding recess. It is a first object of the present invention to obtain a jig in which a tip end surface of a moving member that protrudes and retracts from a jig main body, such as an IC card holding jig capable of engaging and disengaging from a workpiece.

Further, in addition to the structure of the jig described above, the present invention is also applicable to the case where the position of the thinnest portion of the recess for embedding an IC module is different in each of two types of IC modules, for example, 6 terminals and 8 terminals. A jig that can be applied even when the tip end surface of a moving member that protrudes and retracts from the jig main body at a position where it is disengaged from the work is different, such as an IC card holding jig that can also be applied. This is the second purpose.

[0013]

According to the present invention, there is provided a jig in which a distal end surface of a moving member which protrudes and retracts from a jig body is engaged with and disengaged from the work. A through-hole formed in the contact face plate, a moving member mounted in the through-hole, and a distal end portion of which is provided so as to be able to protrude and retract from the outer surface of the contact face plate;
A jig for a work, comprising: a position regulating means for stopping at both a position corresponding to the outer surface of the contact face plate and a position protruding from the position by a predetermined dimension.

According to the present invention, in order to attain the second object, in addition to the above-mentioned configuration, the moving member is further provided such that a rotational position around the axis in the direction of the axis in which the member moves can be changed. The arrangement of the distal end surface of the moving member is a jig for a work that is deviated from the rotation center.

[0015]

The moving member mounted in the through-hole is provided by a position regulating means so that the tip end thereof can protrude and retract from the outer side surface of the contact face plate. For example, the present invention is applied to a jig for IC card printing. When the IC card is used, the tip of the IC card may be protruded from the outer surface of the suction surface plate, which is the contact surface plate, or the position corresponding to the outer surface, that is, the same surface position as the outer surface. Or set it to a concave position and use it.

In the case where the front side of the IC card is sucked by the suction face plate as the contact face plate, the moving member is projected from the outer side by a predetermined dimension, that is, by the depth of the thinnest portion, and the back surface of the IC card is Print the side. Since the distal end surface of the moving member has at least an area compatible with the thinnest portion, the distal end surface of the moving member comes into contact with the thinnest portion. Therefore, the disadvantage that the thinnest portion is sucked toward the suction face plate and curved is avoided.

Further, in the moving member, a rotation position around the axis in the direction of the projecting and retracting axis is provided so as to be changeable, and an arrangement of the distal end surface of the moving member is deviated from the rotation center. In other words, since the arrangement of the distal end face is shifted with respect to the rotation center,
When the moving member is rotated within the through hole by a predetermined angle, the position of the displaced distal end surface shifts with the rotation. By appropriately setting the amount of deviation of this deviation, for example, it is possible to apply to each of the thinnest portions of the embedding recesses where the positions are different between the six terminals and the eight terminals described above.
It is possible to obtain a jig that can be applied even when the position at which the distal end surface of the moving member that protrudes and retracts from the jig main body is disengaged from the work is different.

In FIG. 1, a through hole 2 is formed in the suction face plate 2b.
The moving member 3 is mounted in the through hole 2d. Reference numeral 11 denotes a backing plate which is fixed to the suction surface plate 2b from below the suction surface plate 2b and has a smaller diameter than the through hole 2d of the suction surface plate 2b, and through holes 11b, 11b corresponding to the through holes 2c, 2c. Are formed.

As shown in FIGS. 2 to 4, the moving member 3 has a tip portion 4 slightly smaller in diameter than the through hole 2d of the suction face plate 2b and a smaller diameter portion connected to the lower end of the tip portion 4. A shaft portion 5 is formed, and a screw portion 6 is formed at a lower end of the shaft portion 5.

As shown in FIG. 1, the movable member 3 has a screw portion 6 at the lower end inserted downward from above the through hole 2d of the suction face plate 2b, a coil spring 7 mounted on the shaft portion 5, and 6

A pair of plate members 10 and 10 are fixed to the lower surface of the backing plate 11 at positions sandwiching the through hole 11a. The distance between the plate members 10, 10 is set smaller than the longitudinal width of the locking plate 8 and larger than the lateral width of the locking plate 8.

The moving member 3 is provided so as to be able to protrude and retract from the through-hole 2d, and is provided so that the rotation position around the axis in the direction of the protruding and protruding axis can be changed. That is, the moving member 3 is provided so as to be able to rotate inside the through hole 2d. The emergence and rotation are restricted by a position restricting means described later.

In FIG. 1, reference numeral 4a 'denotes a groove formed in the front end surface 4a. A suitable driver or the like is inserted into the groove 4a' to adjust the rotation angle of the moving member 3.

In FIG. 2, when the locking plate 8 is locked to the pair of plate-like members 10, 10, the moving member 3 has a front end surface 4a of the front end portion 4 outside the suction surface plate 2b. A position corresponding to the side surface 2b ', in this example, the outer side surface 2b'
And the same plane position. And
As shown in FIGS. 3 and 4, in a state where the locking plate 8 is not locked to the pair of plate members 10, 10, that is, in a state where the locking plate 8 is directly in contact with the backing plate 11. The distal end face 4a is provided at a position protruding from the above-mentioned position (the same plane position as the outer side face 2b ') by a predetermined dimension. The predetermined dimension is the thinnest portion 1 of the IC card 1, 1 fed to the IC card holding jig of this embodiment.

Since the arrangement of the tip surface 4a is displaced from the center of rotation p, so to speak, when the moving member 3 is rotated within the through hole 2d by a predetermined angle, the position of the displaced tip surface 4a becomes It shifts with rotation. By appropriately setting the amount of deviation of the deviation, it is possible to apply the deviation amount to each of the thinnest portions of the embedding concave portions where the positions of the six terminals and the eight terminals are different.

In this embodiment, when the moving member 3 is rotated by 180 degrees, the position of the tip surface 4a which is shifted is shifted to the opposite side with the rotation, and the shift amount of this shift is reduced. Appropriately set, it is possible to apply to the thinnest part (in the case of FIG. 3) of the embedded recess of six terminals and the thinnest part (in the case of FIG. 4) of the embedded recess of eight terminals. It has been made to be.
