The marking device 1 includes a ribbon traveling mechanism 9 for traveling a coloring ribbon 11 for coloring characters formed on the medium 2, a ribbon frame 10 to which the ribbon traveling mechanism 9 is attached, a ribbon When the frame 10 is rotatably supported and the coloring ribbon 11 is on standby, the coloring ribbon 11 is placed at a position retracted from the print position of the medium 2, and when coloring, the coloring ribbon 11 is placed on the print 4 and the medium 2.
And a ribbon frame rotating mechanism 12 for rotating the ribbon frame 10 to a position where the ribbon frame 10 can be reached. In addition,
In the embodiment described below, a case where a plastic card is engraved as a typical example of the medium 2 will be described, but this is only an example of the medium 2.

First, the basic structure of the marking device 1 will be described with reference to FIGS. The marking device 1 is mainly configured by a type arm 3, a type 4, a type assembly member 5, a press-contact unit 7, and the like, as shown. The type 4 is prepared by the number of types necessary for forming the embossed character or the indented character. Each type is provided at the tip of the type arm 3 and arranged on the circumference. The type 4 is provided with upper and lower concave and convex (male and female) types, respectively, to form a set. In this embodiment, in order to form indented characters, a flat type on the upper side and a convex type on the lower side are used. As shown in FIG.

The type arm 3 has a rotating shaft 6 as shown in FIG.
And form a rotatable typesetting member 5. The print arm 3 has an elasticity so as to bend by an appropriate amount under the force and to return to its original shape when the force is removed, and is imprinted on the medium 2 by the print 4 when receiving a pressing force in the vertical direction in the figure. Is to be made. Rotary shaft 6
A type arm gear 22 is provided around the area, and a required type 4 can be selected by rotating the type assembly member 5 by driving it by meshing with a motor gear 24 of a type arm drive motor 23.

In order to press the character 4 from above and below and press it against the medium 2, the character pressing shaft 27 and the swing arm 3
A pressure contact means 7 made of 0 or the like is provided. Pressing means 7
Are the upper frame 25 and the lower frame 2 as shown in FIG.
6 are equally arranged at the respective symmetrical positions, so that the upper press-contact means 7 will be described below.

First, the print pressing shaft 27 is arranged at a position directly above the print 4 imprinted on the medium 2 in the upper frame 25, and is slidable in the vertical direction in the figure. A type pressing shaft return spring 28 is provided around the type pressing shaft 27 to urge the type pressing shaft 27 to return to its original position.
A pressing block 29 provided on the head of the type pressing shaft 27
However, the printing press shaft 27 and the swing arm 30 are rotatably connected.

The swing arm 30 is a member that pushes down the type pressing shaft 27 by leverage, and can swing around a fulcrum 31 on the upper frame 25 as shown in the figure. A rotatable cam follower 32 that follows the movement of the cam 33 is provided on the other end of the swing arm 30.

The cam 33 is a rotary member formed in a spiral shape so as to gradually increase in diameter as shown in the drawing. The cam follower 32 is moved up and down with the rotation of the cam 33 to swing the swing arm 30. A step 34 is provided between the large diameter portion and the small diameter portion of the cam 33 so that the cam follower 32 does not ride on the cam 33, and the type press shaft 27 is retracted to a predetermined position by keeping the step 34 in contact with the cam follower 32. I try to get it. The cam 33 is connected via a belt 36 to an upper cam drive motor 35 that can rotate forward and backward so that the cam 33 can freely rotate forward and backward.

The above is the configuration of the portion of the press-contacting means 7 installed on the upper side. On the other hand, the parts installed on the lower side in the drawing are the same members as those on the upper side, that is, the type pressing shaft 37, the type pressing shaft return spring 38, the pressing block 39, the swing arm 40, the fulcrum 41, the cam follower 42, the cam 43, the step 44, The lower cam drive motor 45 and the belt 46 are arranged at symmetrical positions, respectively.

Although not shown in detail, for example, a card as the medium 2 to be engraved is moved to a predetermined position by a transport mechanism 47 as a card transport mechanism including a card stacker, a card hopper, a card holding mechanism, and the like. Is done. According to the transport mechanism 47, the medium 2 can be moved back and forth and right and left in a plane. For convenience, the card longitudinal direction is the Y transport direction of the medium as shown in FIG. Is referred to as a medium X transport direction.

In the present invention, when the marking device 1 forms an indent character, a coloring ribbon 11 is positioned between the surface of the medium 2 and the upper print 4 to color the surface of the medium 2 with a front indent; Contrary to this, description will be made using the expression of back indent coloring on the back side of the medium 2, and in the present embodiment, a configuration is adopted to enable both front indent and back indent. . That is, here, the position of the ribbon running route 14 can be changed, and the indented character is formed while coloring only when necessary, while escaping when unnecessary. Note that the front of the medium (card) 2 is the side that protrudes from the surface of the medium 2 when embossed characters are formed.

To do so, in the marking device 1, the ribbon frame 10 is provided rotatably, and the ribbon frame 10 is moved by the solenoid 13 as a driving means. Therefore, the ribbon frame 10 and the ribbon frame rotating mechanism 12 will be described below.

The ribbon frame 10 includes a ribbon supply spool 57 and a ribbon take-up spool 21 as shown in FIG.
And a ribbon running mechanism 9 so that the coloring ribbon 11 can be supplied during indent character formation. The ribbon supply spool 57 and the ribbon take-up spool 21 are rotatably mounted on the left and right sides of the ribbon frame 10, and can be removed along the center axis at the time of replacement.

First, regarding the ribbon winding side,
As shown in FIG. 9, the ribbon take-up spool 21 has a flange 48 and a holding flange (ribbon take-up flange) 1.
9 is used, and the used coloring ribbon 11 is wound up by rotating. The ribbon take-up spool 21 has the shaft 4
9 and is held down by a ribbon take-up flange mounting knob 20 (hereinafter simply referred to as the knob 20), and rotates together with the shaft 49. The shaft 49 includes a spool boss 70 that is supported by the ribbon frame 10 and fixed thereto. Further, the ribbon take-up spool 21 is provided with irregularities 71 that fit into the spool boss 70 and transmit the rotational force, as shown in FIG.

The holding boss 50 is attached to the tip of the shaft 49 by, for example, a screw 74 as shown in the present embodiment. A knob 20 is provided between the holding boss 50 and the ribbon take-up flange 19 so as to be slidable in the axial direction and rotatable about a shaft 49.
, The knob 20 is urged toward the holding flange 19 side.

Further, two protrusions 68 are formed around the knob 20 at intervals of 180 degrees, for example, as shown in FIG. On the other hand, two grooves 69 through which the projection 68 can pass are formed on the inner periphery of the holding flange 19 and the ribbon take-up spool 21. The inner diameter of the hollow ribbon take-up spool 21 is formed to be slightly larger than the outer diameters of the holding boss 50 and the knob 20. Therefore, the ribbon take-up spool 21 is moved to the ribbon frame 10
When mounting on the first, the fitting is inserted so that the protrusion 68 passes through the groove 69 and shifted to the flange mounting position. Then, the knob 20 is pulled up to the near side, and the protrusion 68 is twisted until the protrusion 68 does not overlap the groove 69. I just need. When the user releases the knob 20 at this position, the projection 68 engages with the portion other than the groove 69, and the ribbon take-up spool 21
So that it does not come off during rotation.

On the other hand, the protrusion 68 is engaged with the groove 69 until the knob 20 is pulled up. Therefore,
By twisting the knob 20 in this state, the ribbon take-up spool 21 can be rotated together with the knob 20 by the same amount.

On the back side of the ribbon frame 10, a ribbon winding motor 55 for rotating the ribbon winding spool 21 is provided. Further, a reduction gear 54 is provided on a shaft 49 of the ribbon take-up spool 21 as shown in FIG. 9 so as to mesh with a gear 56 of a ribbon take-up motor 55 so as to rotate.

Further, it is preferable that the slack of the coloring ribbon 11 can be eliminated when the coloring ribbon 11 is attached. The marking device 1 is provided with the above-described knob 20, and is provided with the slack. It can also be used as a removing means. That is, when the ribbon take-up spool 21 is set on the ribbon frame 10, the knob 2
Turn 0 to rotate the ribbon take-up spool 21 together,
The slack of the coloring ribbon 11 can be removed. After the slack is removed, the tab 20 can be pulled up and twisted to function to bias the ribbon take-up spool 21 as described above.

On the other hand, the ribbon supply spool 57 has basically the same structure as the paired ribbon take-up spool 21 as shown in FIG. 8, and is arranged at a symmetrical position as shown in FIG. It is. However, as shown in FIG. 8, the ribbon supply spool 57 has a structure in which the coloring ribbon 11 is fed under tension so that it can rotate freely without being connected to a motor or the like.

Therefore, a mainspring 52 is provided inside the friction boss 53 on the back side of the ribbon frame 10, and furthermore, the mainspring is rotated when a predetermined torque or more is applied so that no extra tension is applied to the coloring ribbon 11. , So that a constant tension is applied. The mainspring 52 is turned on when the coloring ribbon 11 becomes slack.
Is also rotated to absorb the slack of the coloring ribbon 11.

In this manner, the ribbon supply spool 57 is provided with friction as needed, so that it does not rotate more than necessary when receiving tension (by applying a constant tension to the coloring ribbon 11). Coloring ribbon 11
It is preferable to prevent slack. Alternatively, it is more preferable that the slack is positively removed by the back tension and the friction mechanism.

Next, a configuration for guiding the coloring ribbon 11 from the ribbon supply spool 57 to the ribbon take-up spool 21 will be described. Coloring ribbon 11 supplied
7 is guided by a guide roller 58 and a ribbon guide 59 on the supply side and passes through the ribbon traveling route 14 as shown in FIG.
Is guided to the ribbon take-up spool 21.

In this embodiment, as shown, the ribbon arms 15, symmetrical to the supply side and the winding side, respectively.
15 are provided so as to be swingable, and ribbon guides 59, 59 are attached to the respective ends thereof, whereby each of the ribbon guides 59, 59 is provided.
The height of 59 is variable, and accordingly the ribbon traveling route 1
4, so that the height can be changed. In this case, the ribbon arm fulcrum 17 which is the swing center of the ribbon arm 15
The position of the ribbon arm 1 is not particularly limited.
It is preferable that the length of the entire route of the coloring ribbon 11 does not change as much as possible when the 5 swings. Therefore, in the present embodiment, the ribbon arm fulcrum 17 is provided at a position as shown in FIG. 7 so that the root length of the coloring ribbon 11 hardly differs even if the ribbon arm 15 swings.

Another roller 60 is provided on the other end of the ribbon arm 15. Further, a cam 61 for guiding the roller 60 is provided on the ribbon frame support plate 62 as shown in FIG. The cam 61 is formed so as to face obliquely upward and forward of the marking device 1 as shown. Accordingly, when the ribbon frame 10 is at the retracted position shown in FIG. 1, the roller 60 is located at the rearmost position and is lowered. On the other hand, when the ribbon frame 10 is at the back indent position shown in FIG. . At this time, the ribbon arm 15 swings according to the movement of the roller 60, and the ribbon guide 59 located on the opposite side of the roller 60
Moves in the opposite direction to 0. Therefore, the ribbon guide 59
Rises when the ribbon frame 10 is in the retracted position,
Lower at the back indent position. As a result, the coloring ribbon 1
1 is located on the upper ribbon running route 14 indicated by the imaginary line in FIG. 7 when in the retracted position, while it is moved downward and slid down to the lower side of the medium 2 when changing to the back indent position. I do. Therefore, when coloring is necessary for the indented indented character, the ribbon running route 14 may be changed so that the coloring ribbon 11 is inserted into the medium 2 and the type 4 so as to be located therebetween.

Next, the ribbon frame rotating mechanism 12 will be described. The ribbon frame 10 is shown in FIGS. 1 to 3 so that the ribbon traveling route 14 can be moved between the medium 2 and the type 4 when the indentation of the medium 2 needs to be colored.
As shown in FIG. 7, the hologram is rotatably attached to a fulcrum 63 on a ribbon frame support plate 62. In the present embodiment, the center of rotation on the ribbon frame 10 is disposed slightly rearward as shown in FIG. 1, so that the ribbon frame 10 in a natural state receiving no force is inclined obliquely as shown in FIG. 1. I am trying to become. However, in addition to returning to the retracted state by its own weight, the urging force such as a coil spring or a cam can be used to always apply a rearward urging force to the ribbon frame 10. Needless to say.

When the ribbon frame 10 is not restrained at all, the ribbon frame 10 can rotate forward at least until the ribbon frame 10 reaches a horizontal state as shown in FIG. In the engraving device 1, the ribbon supply spool 57, the ribbon take-up spool 21, and the ribbon frame 10 to which the ribbon traveling mechanism 9 is attached.
While supporting the ribbon frame 10 rotatably,
When the coloring ribbon 11 is replaced, the ribbon frame 10 is provided with a ribbon frame rotating means for rotating the ribbon frame 10 from the type arm 3 to a horizontal state above the drawing, so that the ribbon frame 10 can be replaced when the coloring ribbon 11 is replaced. It is manually rotated so as to be in a horizontal state to improve visibility and operability at the time of replacement. Therefore, when the coloring ribbon 11 is replenished in the marking device 1, the ribbon take-up spool 21 and the ribbon supply spool 57 are kept in this horizontal state.
Can be replaced, the operation is simple, and the coloring ribbon 11 can be reliably hung on the ribbon guide 59 or the like. In this case, it is preferable to keep the ribbon frame 10 horizontal as shown in FIG. 3 in order to facilitate the work. In the present embodiment, the ribbon frame 10 is engaged with the horizontal state of the ribbon frame 10 (not shown) to maintain the state, and a stopper which can be manually released is provided to fix the ribbon frame 10. Further, in the present embodiment, the spool is replaced in the horizontal state. However, the present invention is not limited to this horizontal state, and any position may be used as long as the spool can be easily replaced. The ribbon frame rotating means includes a ribbon frame rotating mechanism 12 for rotatably supporting the ribbon frame 10 and a means for rotating the ribbon frame 10 to a predetermined position (for example, using a solenoid 13 in addition to manual operation). And may use a coil spring or the like (not shown) to urge the ribbon frame 10).

The ribbon frame 10 is normally in an inclined state (retracted state) as shown in FIG. 1 as shown in FIG. 1. It is sufficient to rotate the ribbon frame forward as shown in FIG. 2 only when performing back indentation. . The means for rotating in this manner is not particularly limited, but in the present embodiment, the ribbon frame 10 is rotated using the solenoid 13 as a driving means. In this case, the ribbon frame 10 may be directly extruded by the solenoid 13,
Here, as shown in FIG. 3, a swinging member 64 that swings in response to the movement of the tip of the plunger of the solenoid 13 and that pushes out and rotates the back surface of the ribbon frame 10 is interposed as shown in FIG. As shown in FIG. 3, the swing member 64 is provided with an urging spring 67 so as to always urge the rocking member rearward.

Here, since the ribbon running route 14 must be accurately moved between the medium 2 and the lower print 4 at the time of back indentation, the ribbon frame 10 is positioned as accurately as possible in the vertical state shown in FIG. Is preferred. Therefore, in the present embodiment, a hook-shaped stopper 16 for regulating the position of the ribbon frame 10 at the time of back indentation is provided. The stopper 16 has a hook for hooking on the upper side as shown in FIG. 3, and is provided integrally with the above-mentioned swinging member 64 so as to swing together.
On the other hand, as shown in FIG. 7, a vertical hole 65 that engages with the stopper 16 is provided on the ribbon frame 10 side.

The stopper 16 is normally lowered as shown in FIG. For this reason, the claw of the stopper 16 does not catch on the vertical hole 65, and is in a state in which the restriction on the ribbon frame 10 is not performed. Therefore, the ribbon frame 10
Can be manually rotated freely from the retracted position shown in FIG. 1 to the horizontal position shown in FIG. 3 without being restricted by the stopper 16.

On the other hand, when the ribbon frame 10 is rotated forward not by the manual operation but by the action of the solenoid 13, the stopper 16 functions and the movement is restricted, so that the ribbon frame 10 stops in the vertical posture shown in FIG. That is, when the solenoid 13 is excited in the retracted state shown in FIG.
The plunger pops out and rotates the ribbon frame 10 forward through the swing member 64. At this time, the stopper 16 also swings at the same time, rises in the vertical hole 65, and hooks the claw on the ribbon frame 10. That is, the solenoid 13
When the ribbon frame 10 is actuated, the ribbon frame 10 is rotated,
Can be stopped at a predetermined vertical position (back indent position).

Here, as described above, the stopper 1
6, the ribbon frame 10 is positioned, but it can also be positioned by other methods. For example, the stopper 16 is connected to the ribbon frame 10
The position of the ribbon frame 10 may be adjusted to a predetermined position by engaging a solenoid 13 or a cam. In addition,
When the ribbon frame 10 is positioned by the stopper 16, the solenoid 13, and the cam, it is desirable that fine adjustment can be performed. Therefore, in the present embodiment, as shown in FIG.
The stop position of the ribbon frame 10 can be finely adjusted by turning the adjustment screw 66.

Further, in the marking device 1 which can rotate until the ribbon frame 10 becomes horizontal as described above, the stopper 16 is provided so as to regulate the rotation of the ribbon frame 10 but not to hinder it. Needless to say. In the marking device 1, when the ribbon frame 10 is manually rotated, the stopper 16 always passes through the vertical hole 65 and does not hit the periphery thereof.

It is preferable that the ribbon frame 10 is provided with a fixing means for non-rotatably fixing the ribbon frame 10 to the ribbon frame support plate 62 as necessary. In this embodiment,
As shown in FIG. 6 and FIG.
A screw hole 72 is provided at the tip of the
A screw hole 73 corresponding to the screw hole 72 is provided above. According to this, when transporting the marking device 1, the ribbon frame 10 can be attached to the ribbon frame support plate 62 with screws, and the ribbon frame 10 can be prevented from rattling. Further, although not particularly shown, another screw hole may be provided so as to be fixed in the retracted state shown in FIG. In this case, when only the units forming the indented characters and the embossed characters are transported, the unit is fixed at the position shown in FIG. 1 so as not to enlarge the entire unit. It is also possible to appropriately adopt a fixed state according to the transportation mode, such as fixing at a horizontal position shown in FIG.

The operation of the marking device 1 will be described below. In addition, the marking device 1 is a shared machine that can independently form an embossed character and an indented character (including both a front indent and a back indent). Therefore, the embossed character and the indented character are appropriately selected. Can be done.

First, in the case where only processing for forming an embossed character on the surface of the medium 2 is performed, assuming that coloring is not necessary, the coloring ribbon 11 needs to be retracted from the position of the type 4. Therefore, in this case, the ribbon frame 10 is not rotated, and the coloring ribbon 11 remains in the retracted state as shown in FIG. Then, the type arm drive motor 23 is driven to rotate the type assembly member 5 to appropriately select the type 4, and the medium 2 is moved by the transport mechanism 47 so that the character position matches the position of the type 4. Also, the upper and lower cam drive motors 35 and 45 are operated to drive the cams 33 and
When the 43 is rotated, the upper and lower swing arms 30 and 40 swing about the fulcrums 31 and 41, and push down the print pressing shaft 27 via the pressing blocks 29 and 39 (push up the print pressing shaft 37) and print the print 4. , 4 are pressed against the medium 2 from above and below to imprint.

Next, when forming the indented characters, the grooves are colored with the coloring ribbon 11. In this case, the coloring ribbon 11 is attached to the medium 2 and the lower type 4 at the time of coloring. The ribbon traveling route 14 is moved by rotating the ribbon frame 10 so as to be interposed therebetween. In this case, as described above, the solenoid 13 may be excited and the ribbon frame 10 may be rotated via the swinging member 64.
6, the movement of the ribbon frame 10 is restricted, and the ribbon frame 10 is held in the vertical state shown in FIG.

As the ribbon frame 10 rotates, the rollers 60 run up the slope of the cam 61 to swing the ribbon arm 15 and lower the ribbon traveling route 14. As a result, the coloring ribbon 11 descends while moving forward, and changes its position from the retracted state shown in FIG. 1 to a state in which lower indentation shown in FIG. 2 is possible. In the marking device 1, the ribbon frame 10 is rotated before the medium 2 is transported to the marking position, and the medium 2 is moved after the ribbon traveling route 14 is changed.

When the coloring ribbon 11 is replaced, the ribbon frame 10 is manually rotated to be in a horizontal state and then engaged with a stopper (not shown) to be fixed in a horizontal state as shown in FIG. I do. So, knob 2
Turn 0 to release the engaged state and take up the ribbon take-up spool 2.
1 and the ribbon supply spool 57 can be freely removed. When exchanging the coloring ribbon, the stopper 16 does not act because the solenoid 13 is not excited, so that the ribbon frame 10 can rotate to the horizontal position without being restricted.

The above embodiment is an example of a preferred embodiment of the present invention, but the present invention is not limited thereto, and various modifications can be made without departing from the gist of the present invention. For example, in the above-described embodiment, the case of the back indent in which the coloring ribbon 11 is sandwiched between the medium 2 and the lower print 4 has been described, but the form of the engraving is not particularly limited to this. That is, the reverse indentation is such that the coloring ribbon 11 is sandwiched between the surface of the medium 2 and the upper print 4, and the structure of the above-described marking device is appropriately changed to change the ribbon running route 14. It becomes possible by changing the moving width of the.

Further, the present invention is not limited to coloring when forming indented characters, and may be used when coloring is required when forming embossed characters.

Further, in this embodiment, the ribbon arm 15 is swung by using the roller 60 running up the cam 61, but the means for swinging is not limited to this. For example, the other end of the wire having one end fixed to the ribbon frame support plate 62 may be connected to the ribbon arm 15, and the ribbon arm 15 may be swung by pulling the wire when the ribbon frame 10 rotates.
Further, the left and right ribbon arms 15 may be connected to each other by a link, and when one of the ribbon arms 15 is swung, the other ribbon arm 15 may be swung in synchronization.

As is apparent from the above description, according to the marking device of the present invention, the ribbon frame can be rotated until it reaches a predetermined position, and therefore, the ribbon mounted on the ribbon frame can be rotated. It is possible to ensure convenience when replacing the take-up spool and the ribbon supply spool. At this time, since the rollers and guides also move from narrow places, the work of hanging a new ribbon can be easily performed.

According to the marking device of the second aspect of the present invention, the ribbon can be retracted by rotating the ribbon frame, and the marking can be performed without coloring. Also,
By moving the ribbon away from the surface of the medium at a distance, the movement of the medium is not hindered.

Further, according to the marking device of the third aspect of the present invention, since the ribbon frame is manually rotated at the time of ribbon exchange, power for rotating the ribbon frame is not required, and the apparatus is not required. Can be simplified.

According to the engraving device of the fourth aspect, at the time of indentation, the ribbon frame is rotated to a position where the ribbon faces between the print and the medium, so that engraving and coloring without coloring are performed simultaneously. Any of the indentation processes can be performed. In addition, the user can select one of them simply by rotating the ribbon frame, so that the switching is easy.

Further, the marking device according to the fifth aspect of the present invention has a simple configuration and has necessary functions since the slack of the ribbon can be removed by rotating the ribbon winding flange mounting knob.

According to the marking device of the sixth aspect,
The cam follower at the tip of the swing arm follows the rotating cam, and the swing arm is swung to press the type on the medium. In this case, since the cam transmission is used, the characters can be stamped by pressing the characters with the pressing force required for the stamping.
