Abstract

PURPOSE:To prolong the useful life of a top pad and effectively prevent a top face from being deformed, by a system wherein a pressing part of a top pattern forming body drives a side pattern forming body to rotate relative to a lift body through an energizing member, and a side pad can be pressed against a side face of a member to be provided with a pattern, with a transfer sheet therebetween. CONSTITUTION:Even when the thickness of a top pad 2a or a side pad 3a is reduced due to deterioration with the result of a reduction in a pressure exerted on a side face 8b of a key cap 8, appropriate pressures can be applied to a top face 8a and the side face 8b of the key cap 8 by energizing both pattern forming bodies 2, 3 while reducing the flexure quantity of a leaf spring 4, whereby patterns can be securely formed. The spring 4 is set to be deflected when an overload is about to be exerted because of the pressure reaching or exceeding a predetermined value, whereby the overload can be effectively prevented from being exerted, and deterioration of the pads can be effectively prevented. The useful life of the top pad 2a can be prolonged by reducing the thickness and enhancing the hardness of the pad.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a pattern forming device for forming patterns such as letters and symbols on the top and side surfaces of a pattern forming member such as a synthetic resin molded product.

BACKGROUND OF THE INVENTION Conventionally, this type of pattern forming apparatus has been used for forming parts such as synthetic resin molded products, for example, keyboards for bush type telephones, desktop electronic computers, typewriters, wide-band processors, personal computers, etc. It is used to completely form patterns such as letters and symbols on the top and side surfaces of keycaps used in the department. As an example of the pattern forming apparatus, as shown in FIGS. 4 and 5, an elevating body 20 is arranged to be movable up and down on a base (not shown) on which a key cap 25 as a pattern forming member is placed. , a top pattern forming body 23 which is supported to be vertically movable relative to the lift body 20 and has a top pad 23a fixed to its lower end, and a bent portion 22b of a dogleg-shaped plate material are attached to the lift body 20. The upper end connecting portion 22 is rotatably supported between the initial position C and the pressing position by the support shaft 26.
c is in contact with the upper end 23b of the top pattern forming body 23, and the side pattern forming body 22 has the side pad 22a fixed to the lower end side surface, and the side pattern forming body 22 is rotated so as to return to the initial position C. The coil spring 21 is configured to provide a biasing force. Then, attach the key cap 25 to the base above.
After placing the transfer sheet 24 on the upper side of the keycap 25, the elevating body 20 is lowered and the top surface pad 23a of the top pattern forming body 23 is used to transfer the top surface of the transfer sheet 24 made of heat-transferable dye. By pressing the pattern 24a against the top surface 25a of the keycap 25 and still lowering the elevating body 20, the top pattern forming body 23 rises relative to the elevating body 20, and the side pattern forming body 22 The side surface pattern forming body 22 is forcibly rotated around the support shaft from the initial position C toward the pressed position by pressing the connecting portion 22c upward, and the side surface made of the heat-transferable dye of the transfer sheet 24 is moved by the side surface pad 22a. By pressing the pattern 24b against the side surface 25b of the keycap 25, the heat-transferable dye of each pattern 24a, 24b is transferred to the keycap 2 by heating the keycap 25, the top pad 23a, and the side pad 22a.
The pattern is formed by moving onto the top surface 25a and side surface 25b of No. 5 (Japanese Patent Laid-Open No. 61-20000)
No. 0). The pads 23a and 22a are made of a heat-resistant elastic material such as silicone rubber.

Problems to be Solved by the Invention However, in the structure described above, the top pad 23a
is applied to the top surface 25 of the keycap 25 via the transfer sheet 24.
After contacting and being stopped by a, the top pattern forming body 23 rises relative to the descent of the elevating body 20,
By raising the connecting portion 22c of the side pattern forming body 22 at the upper end 23b of the top pattern forming body 23 by the amount of rise, the side pattern forming body 22 is rotated around the support axis, and the side pad 22a is attached to the transfer sheet 24. Since the top pad 23a is pressed against the side surface 25b of the keycap 25 through the key cap 25, when the thickness of the top pad 23a decreases during use, the amount of rise of the top pattern forming body 23 decreases.
The rotation angle of the side surface pattern forming body 22 becomes smaller, and the side surface pad 2 relative to the side surface 25b of the keycap 25
There was a problem in that the pressing force of 2a was reduced and pattern formation could not be performed well.

One way to solve this problem is to
The pressing force of the top pad 23a against the keycap 25 is increased in advance by the decrease in pressing force due to deterioration of the key cap 3a, etc., so that even if the thickness of the top pad 23a decreases due to deterioration, etc., the pressing force by the top pad 23a can be increased. It is considered that the pressure can be maintained at an appropriate value.

However, if an unnecessarily large pressing force is applied to the top pad 23a, an overload will be applied to the top pad 23a, resulting in premature damage to the top pad 23a.
3a is severely deteriorated, and an overload acts on the top surface 25a of the keycap 25 rather than the top pad 23a, causing the top surface 25a of the keycap 25 to easily deform.

Therefore, an object of the present invention is to solve the above-mentioned problem, and to prevent the top surface pattern forming body from exerting an undue pressing force on the pattern forming member. It is an object of the present invention to provide a pattern forming device that can reliably form a pattern on a side surface, improve the life of a top pad, and effectively prevent deformation of the top surface of a pattern forming member.

Means for Solving the Problems In order to achieve the above object, the present invention includes a biasing member between the top pad and the side pad, so that the thickness of the top pad is reduced to prevent the top from turning. Even if the upper limit of the formed body decreases, the side surface pattern forming body is rotated by a predetermined amount by the biasing force of the biasing member, so that the side surface pad is reliably pressed against the side surface of the pattern forming member. That is, either between the pressing part of the top surface pattern forming body and the top surface (rad) or between the pressing part of the top surface pattern forming body and the connecting part of the side surface pattern forming body. A biasing member is interposed between the top surface pattern forming body and the upward movement of the top surface pattern forming body relative to the elevating body so that the pressing portion of the top surface first turn forming body presses the connecting portion of the side surface pattern forming body via the biasing member. While pressing the side surface 7 to rotate the turn-forming body relative to the elevating body, the biasing force of the biasing member causes the side pad of the turn-forming body to be pressed against the side surface of the pattern-forming member. The structure is such that it can be pressed and biased through the transfer sheet.

Effect of the Invention In the above structure, the elevating body moves up and down with respect to the pattern forming member on the base, and the top pad of the top pattern forming body of the elevating body moves the heat transferable dye of the transfer sheet. At the same time, the top pattern forming body of the elevating body contacts the pattern forming member via the transfer sheet and its descent is regulated, and then the above When rising relative to the elevating body, the pressing portion of the top pattern forming body presses the biasing member. At this time, the biasing member presses the connection portion of the side pattern forming body without bending much to rotationally drive the side pattern forming body, and the side pad of the side pattern forming body causes the heat transfer of the transfer sheet to be A side pattern made of dye is pressed onto the side surface of the pattern forming member. When the thickness of the top pad deteriorates due to use, etc., and the amount of rise of the top pattern forming body decreases, the biasing force of the biasing member is applied to the top pattern forming body and the side pattern forming body. The side pattern forming body is reliably pressed against the side surface of the pattern forming member through the transfer sheet. When the top surface pattern and the side surface pattern of the transfer sheet are pressed against the top surface and side surfaces of the pattern forming member, respectively, the respective patterns are formed.

Embodiments of the present invention will be described in detail below with reference to FIGS. 1 to 3.

As the elevating body 1 descends, the top pattern forming body 2 whose descent is prevented by the key cap 8 rises with respect to the elevating body l, and the engaging protrusion 2e of the top pattern forming body 2 moves forward. The urging force of the returning coil spring moves the front side pattern forming body 3 from the initial position A to the pressing position B via a plate spring 4 made of metal, for example, as a biasing member provided on the connecting portion 3d of the side pattern forming body 3. The front side pattern 9b of the transfer sheet 9 is applied to the keycap 8 by the front side pad 3a of the front side pattern forming body 3.
The pattern of the transfer sheet 9 is transferred to the keycap 8 by pressing the front side surface 8b of the keycap.

As shown in FIG. 3, this transfer sheet 9 has patterns 9 a of characters, symbols, etc. on the bottom surface of the base sheet 9 c on the base 12 side for the top surface and front surface of the keycap 8, respectively.
, 9b. The base sheet 9c may be a sheet-like material used for the transfer sheet 9, such as paper such as medium-quality paper, high-quality paper, uncoated paper such as kraft paper, metal foil such as aluminum foil, polybutylene terephthalate film, etc. , a heat-resistant synthetic resin film such as a polyethylene terephthalate film, a vinyl chloride film, a nylon film, or a laminate film of these films. The above pattern is formed by printing using ink containing a heat-transferable dye. The heat-transferable dye should preferably be one that is easily thermally diffused during heat treatment.
For example, disperse dyes, oil-soluble dyes, basic dyes, etc. are preferred.

The above pattern is formed as a set of a top surface pattern 9a and a front surface pattern 9b, and the front surface pattern 9b is the top surface pattern 9a among the four sides of the surrounding rectangle.
A cutting line 1.1 is formed on the remaining three sides excluding the tangent side.

This cutting line 11 is a half cut in which a cut is made up to half the thickness of the base sheet 9c, or

The keycap 8 is made of a material that can be dyed with a heat-transferable dye. That is, the material of the key cap 8 includes, for example, synthetic resins such as polybutylene terephthalate, polyethylene terephthalate, polycarbonate, triacetate, diacetate, polyether sulfone, aromatic nylon, and 6-row nylon, as well as metal surfaces. It is preferable to overcoat the above synthetic resin. The shape of the keycap 8 is not limited to one in which the top surface 8a is planar, but may also have a concave or convex shape.

The top pattern forming body 2 is a substantially rod-shaped body, and is fitted into the groove lb of the elevating body 1 so as to be vertically movable. Insert the protruding pin 2d into the elongated hole l.

At step a, the pattern 9a for the top surface of the transfer sheet 9 is pressed against the top surface 8a of the keycap 8 so that it comes into close contact with the top surface 8a.

A coil spring 7 for driving the top pattern forming body is provided in the recess 2c formed along the axial direction from the upper end surface of the top pattern forming body 2, and the biasing force of the driving coil spring 7 is applied to the top pattern forming body 2. is constantly biased downward against the elevating body 1. An engaging protrusion 2e as a pressing portion is formed at a predetermined location on the outer peripheral surface near the upper end of the top pattern forming body 2 so that it can engage with the connecting portion 3d of the front pattern forming body 3. Make it.

The front side pattern forming body 3 is made of a lever in the shape of an abbreviation, and the bending portion 3f of the front side pattern forming body 3 is passed through a support shaft 6 fixed to the elevating body 1, so that the front side pattern forming body 3 is vertically rotated around the support shaft. Support for reverse rotation. Front side pattern forming body 3
A front side pad 3 made of a heat-resistant elastic material such as silicone rubber with a hardness of 5 to 50 degrees is provided on the side surface of the lower end 3C.
a, the front side pad 3a allows the transfer sheet 9
The front side pattern 9b is pressed against the front side of the keycap 8, and the transfer sheet 9 is bent at the tangent edge between the top pattern 9a and the front side pattern 9b, and the area around the front side pattern 9b is pressed. The front surface pattern 9b is pressed against the front surface of the keycap 8 so as to be brought into close contact with the front surface by cutting along the cutting line 11. A protruding spring locking portion 3b is formed at a predetermined location between the bent portion 3f and the lower end 3c of the front side pattern formed body 3. The above-mentioned return coil spring 5 is
One end thereof is locked to the spring locking portion 3b and the other end is locked to the locking protrusion lO of the elevating body l, and the front side pattern forming body 3 is moved from the pressing position B shown in FIG. It is constantly urged to rotate so that it returns to the initial position A shown in FIG. A recess 3e recessed along the axial direction is formed in the upper end connecting portion 3d of the front side pattern forming body 3, and the U-shaped temporary spring 4 is fitted into the recess 3e. One end of this leaf spring 4 is engaged with the upper surface within the recess 3e, and the other end is made to protrude outside from the recess 3e to form the engagement protrusion 2e of the top pattern forming body 2.
so that it can be engaged with.

According to the above configuration, the keycap 8 is placed on the base 12, and the transfer cartridge 9 is placed above the keycap 8.

After heating the key cap 8, the top pad 2a, and the front pad 3a, the elevating body 1 is lowered toward the base 12 as shown in FIG. The top pad 2a presses the top pattern 9a of the transfer sheet 9 against the top surface 8a of the keycap 8, and the top pad 2a itself begins to deform within its elastic deformation range.

At this time, at the same time, the front side pattern 9b of the transfer sheet 9 is pressed against the base 12 side by the front side pad 3a of the front side pattern forming body 3. As the elevating body 1 further descends, the top pad 2a of the top pattern forming body 2 is elastically deformed and pressing the top surface 8a of the keycap 8 via the transfer shift 9. When the key cap 8 prevents the key cap 8 from lowering, the top pattern forming body 2 begins to move upward in contrast to the elevating body 1. By this upward movement of the top pattern forming body 2, the engaging protrusion 2e of the top pattern forming body 2 engages with the protruding end of the leaf spring 4 of the front pattern forming body 3.

In a state where the front side pattern forming body 3 is not pressing the front side surface 8b of the keycap 8, that is, in a state where it can freely rotate, the leaf spring 4 hardly bends even if the top surface pattern forming body 2 contacts it. . Therefore, as the top pattern forming body 2 rises, the front side pattern forming body 3 is rotated clockwise in FIG. Pad 3a
is brought close to the front side surface 8b of the keycap 8. As the top pattern forming body 2 rises relative to the elevating body 1, the front side pattern forming body 3 rotates around the support axis, and the front side pad 3a cuts along the cutting line around the front side pattern 9b of the transfer sheet 9. 11 and press the front side pattern 9b onto the front side of the keycap 8. Further, as the top pattern forming body 2 rises, the front side pad 3a of the front side pattern forming body 3 presses the front side 8a of the keycap 8 via the front side pattern 9b of the transfer channel 9. As a result, the front side pad 3a begins to deform within its elastic deformation range, and the force pressing the transfer sheet 9 against the front side 8b of the keycap 8 gradually increases. This pressing force reaches a predetermined level, and the front surface pattern forming body 3 is about to apply an overload to the front surface 8b of the keycap 8, or the top surface pattern forming body 2 causes the keycap 8 to become overloaded. When an overload is about to act on the top surface 8a, the leaf spring 4 begins to bend, thereby preventing the overload from acting on the top surface 8 or the front side 8b of the keycap 8. Note that it is preferable that the plate spring 4 be able to bend within the recess 3e of the front side pattern forming body 3 by about 0.5 to 2.0 mm. This is because if the temporary spring 4 can be bent to this extent, even if the thickness of each pad 2a, 3a decreases due to changes over time, the amount of deflection of the leaf spring 4 will decrease, and the biasing force will be reduced. This is because the pressing force against each surface of the keycap 8 can be increased to a predetermined level by acting on each pattern forming body 2.3. That is, an additional pressing force can be applied to each surface of the keycap 8 by the amount of deflection of the leaf spring 4, as long as no overload is applied.

When the top surface pattern 9a and front surface pattern 9b of the transfer sheet 9 are pressed and brought into close contact with the top surface 8a and front surface 8b of the keycap 8, respectively, the keycap 8, the top surface pad 2a, and the front surface pad 3a are Since the transfer sheet 9 is heated in advance, each pattern 9a, 9b of the transfer sheet 9 is heated, and the heat-transferable dye of each pattern 9a, 9b is activated. When the activated state of the heat transferable dye continues for a certain period of time, the heat transferable dye transfers to the top surface 8a of the keycap 8.
and the front side surface 8b, and a predetermined pattern is formed on each surface 8b.
Formed in a, 8b.

When each of the above patterns is formed on the keycap 8,
The elevating body 1 is raised to separate the top pad 2a and the front pad 3a from the key cap 8, and the front pattern forming body 3 is rotated to the initial position A by the biasing force of the return coil spring 5, while the key cap 8 Transfer sheet 9
Let go. This completes the pattern forming work for the keycap 8.

According to the above embodiment, when the top pattern forming body 2 contacts the top surface 8a of the keycap 8 and its downward movement is restricted,
The top pattern forming body 2 rises above the elevating body 1, and the front pattern forming body 3 is rotated toward the pressing position B without bending the leaf spring 4 much at first, and the front surface pad 3
．． a to the front side 8 of the keycap 8 via the transfer sheet 9
b and press the top surface 8a and front surface 8b of the keycap 8.
The pressing force against each surface 8a reaches a predetermined pressing force.

When an overload is about to be applied to 8b, the leaf spring 4 begins to bend to absorb this. Even if the top pad 2a deteriorates during use and its thickness decreases and the amount of rise of the top pattern forming body 2 decreases, or if the side pad 3a deteriorates and its thickness decreases. Even if the pressing force against the side surface 8b of the keycap 8 decreases,
The amount of deflection of the plate spring 4 is reduced, and both pattern forming bodies 2.
By applying a biasing force to 3, the top pattern forming body 2 can be lowered and the top pad 2a can be pressed against the top surface 8a of the keycap 8 with a predetermined pressure, while the side pattern forming body 3 can be rotated. By driving, the side pad 3a can be pressed against the side surface 8b of the keycap 8 with a predetermined pressure.

Therefore, an appropriate pressing force can be applied to the top surface 8a and side surface 8 of the keycap 8, and each pattern can be reliably formed. Further, when the top pattern forming body 2 is pressed against the top surface 8a of the keycap 8 and the pressing force exceeds a predetermined value and an overload is likely to be applied, the temporary spring 4 is bent. keycap 8
It is possible to effectively prevent overload from being applied to the top surface 8a and front surface 8b of the vehicle.

Further, no overload is applied to the top pad 2a of the top patterned body 2 and the front pad 3a of the front patterned body 3, and deterioration of each pad can be effectively prevented. Furthermore, if the pressing force exerted by the top pattern forming body 2 is too large with respect to the top surface 8a of the keycap 8, this can be absorbed by bending the leaf spring 4, so that the top surface pad The silicone rubber layer 2a can be made of a material having a small thickness and high hardness, that is, a material with a long life and high thermal conductivity, and the pressing force of the keycap 8 of the top pad 2a against the top surface 8a can be reduced. Fine adjustment is no longer necessary, and the adjustment effort can be saved.

Note that the present invention is not limited to the above embodiments,
It can be implemented by various other @-sama. For example, the return mechanism for the front side pattern formed body 3 is not limited to the return coil spring 5, but a spring may be used to perform the same action as described above. Furthermore, the front side pattern-formed body 3 is not limited to an L-shaped plate, but may be an elongated plate having a constant size and having a circular portion that fits into the support shaft 6. Further, the plate spring 4 is not limited to a U-shaped curved spring, but may be formed of a simple plate, or a coil spring may be formed between the engagement protrusion 2e of the top pattern forming body 2 and the front side pattern forming body 3. The same effect may be achieved by compressing the connecting portion 3d between the connecting portion 3d and the connecting portion 3d. Further, the biasing member is not limited to the leaf spring 4, but may be applied to the top pad 2a of the top pattern forming body 2 and the engaging protrusion 2.
It is also possible to provide the same effect as above by interposing the element between the element and the element e.

Effects of the Invention According to the above configuration, when the top pattern forming body contacts the top surface of the pattern forming member and its descent is regulated, the top pattern forming body rises with respect to the elevating body, and the biasing member The front side pattern forming body is rotationally driven to the pressing position side through the
The front side pad is pressed against the front side of the pattern forming member through the transfer sheet, and the pressing force against the top surface and front side of the pattern forming member reaches a predetermined pressing force, so that an overload is likely to be applied to each surface. Then, while the biasing member starts to bend, for example, the top pad etc. deteriorates and its thickness decreases, the amount of rise of the top pattern forming body decreases, and the pressing force of the side pads decreases. Even when the biasing force of the biasing member acts on both pattern forming bodies, the side pattern forming body can be rotationally driven and the side pad can be pressed against the side surface of the pattern forming member. Therefore, an appropriate pressing force can be applied to the top surface and side surfaces of the pattern forming member without applying a large pressing force greater than the appropriate level to the top surface of the pattern forming member using the top pad. Each can be formed reliably. Further, when the top pattern forming body is pressed against the top surface of the pattern forming member and the pressing force exceeds a predetermined value and an overload is likely to be applied, the biasing member is bent. It is possible to effectively prevent overload from acting on the top and front surfaces of the vehicle. Further, no overload is applied to the top pad of the top pattern formed body and the front side pad of the front side pattern formed body, and deterioration of each pad can be effectively prevented. If the pressing force from the secondary top surface pattern forming body is too large with respect to the top surface of the pattern forming member, the biasing member can absorb this force by bending. The face pad can be made to have a small thickness and high hardness, that is, it has a long life and high thermal conductivity, and there is no need to finely adjust the pressing force of the pattern forming member of the top pad against the top face. , the adjustment effort can be saved.
