DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to an electrophotographic copying machine,
The present invention relates to a film-shaped electrode used for arranging electrodes of an electrodeless lamp used as a light source lamp of an OA device such as an image scanner, a method of manufacturing the same, a manufacturing apparatus thereof, and a lamp using the film-shaped electrode.

[0002]

2. Description of the Related Art Conventionally, a cold cathode discharge lamp has been used as a light source for OA equipment. However, since the cold cathode discharge lamp has a low luminous efficiency and a low luminous speed, an electrodeless lamp in which these are improved has recently been awarded in OA equipment which requires high performance.

[0003] This electrodeless lamp is, as shown in FIG.
A rare gas such as xenon is sealed in the hollow of the cylindrical glass tube 31 whose both ends are closed.
An electrode member 32 as shown in FIG. The electrode member 32 includes a transparent film 33, a pair of rectangular aluminum electrodes 34 arranged in parallel on one surface of the transparent film 33, and a rectangular aluminum electrode 3.
4 and a connection terminal 35 attached to the top of the connector 4. The transparent film 33 and the rectangular aluminum electrodes 34 are adhered to each other by a film-side pressure-sensitive adhesive layer formed on the entire surface of the transparent film 33. On the surface opposite to the attachment surface), an adhesive layer for attaching electrodes is formed. The electrode member 32 is attached to the glass tube 3 by utilizing the adhesive strength of the film-side adhesive layer and the electrode-adhering adhesive layer.
1 is attached to the outer peripheral surface.

In order to automate and simplify the operation of attaching such electrode members 32 to the outer peripheral surface of the glass tube 31, a large number of electrode members 32 as shown in FIG. The film electrode 37 detachably attached to the strip separator 36 is mechanically manufactured in series using the adhesive force of the layer and the pressure-sensitive adhesive layer for electrode attachment, and then the electrode members 32 are separated one by one from the separator 36. It has been proposed to peel it off and attach it to the outer peripheral surface of the glass tube 31.

[0005] The film-like electrode 37 can be manufactured, for example, as follows. That is, first, an acrylic pressure-sensitive adhesive is applied to one surface of the belt-like separator 36 by a comma coater or the like to form a pressure-sensitive adhesive layer for electrode attachment, and a belt-like aluminum sheet 38a is formed on the surface of the pressure-sensitive adhesive layer for electrode attachment. Electrode base material 38 obtained by dry laminating (a roll-shaped wound body, see FIG. 12)
Prepare Next, as shown in FIG. 12, the aluminum sheet 38a on the surface is half-cut by the half-cutting device 20 while the aluminum electrode base material 38 is fed out in a band shape, so that a strip-like aluminum electrode shape is developed (the cut portion is formed). shown by a dotted line L _11). At this time, 2
A set of individual strip-shaped aluminum electrodes 34 are juxtaposed at predetermined intervals. Next, an unnecessary portion of the aluminum sheet 38a is sequentially peeled off by the unnecessary aluminum removing device 21 to form a pair of strip-shaped aluminum electrodes 34. In this manner, a film 39 with electrodes, in which a large number of strip-shaped aluminum electrodes 34 are attached to the separator 36, is obtained, and is wound up in a roll. When the unnecessary aluminum portion is peeled off, the pressure-sensitive adhesive layer for electrode attachment at that portion is removed together with the unnecessary aluminum portion.

On the other hand, a silicone-based pressure-sensitive adhesive is applied to one surface of a strip-shaped transparent film 33 by a comma coater or the like, and a laminated film 40 having a film-side pressure-sensitive adhesive layer formed thereon.
Is prepared (see FIG. 13). In addition, the laminated film 4
0, when a roll-shaped wound body is used for easy storage and transportation, a separator for protecting the pressure-sensitive adhesive layer is attached to the surface of the pressure-sensitive adhesive layer on the film side, and the separator for protecting the pressure-sensitive adhesive layer is used at the time of use. The separator may be peeled off.

[0007] Then, as shown in FIG. 13, the electrode-attached film 39 and the laminated film 40 (both in a roll form) are fed out and passed between the opposing movable rollers 22. And the surface of the laminated film 40 on which the film-side pressure-sensitive adhesive layer is formed is joined to integrate the two. At this time, the connection terminal 3 is connected to one end of the strip-shaped aluminum electrode 34.
It is preferable to interpose an ear separator 41 between the electrode-attached film 39 and the laminated film 40 as shown in FIG. This is for making it easier to peel off one end 33a of the transparent film 33 described later. Further, in the integrated film, the strip-shaped aluminum electrode 34 is covered with the transparent film 33, and the separator 36 side is kept flat.

Next, from the integrated film, a transparent film 3 between one set of strip-shaped aluminum electrodes 34 and another set of strip-shaped aluminum electrodes 34 adjacent thereto is formed.
3 of at least a portion nicking L ₁₂ by partly cutting apparatus 23. The cut L ₁₂ are two between pairs adjacent to each other.

Subsequently, the unnecessary portion 3 of the transparent film 33
Remove 3b. Then, ear separator one end 33a of the portion of the transparent film 33 sandwiched by the slit L ₁₂ (1 set of partial covering the strip-shaped aluminum electrode 34) 4
1 and raise the one end 33a by about 90 °. Then, the one end portion 33 is formed by the ear separator 41.
a is held upright at about 90 °. Then, a conventionally known thermosetting conductive adhesive is applied to the exposed end surface of the strip-shaped aluminum electrode 34 by a dispenser 42. Then, the connection terminal 35 is mounted on one end of the strip-shaped aluminum electrode 34 by placing the connection terminal 35 on the application surface. Then, the ear separator 41 is wound up, and one end 3 of the peeled transparent film 33 is so exposed that the connection terminal 35 of the strip-shaped aluminum electrode 34 is exposed from one side edge of the transparent film 33 to the outside.
3a is attached again by a roller (not shown) to complete the film electrode 37. The film-like electrode 37 completed in this way is used for connection terminals 3 during storage and transportation.
5 is wound in a roll shape while sandwiching the cushion member 43 so as not to damage the cushion material 43, and is supplied to a production line of an electrodeless lamp after the curing process of the thermosetting conductive adhesive.

In the production line of the electrodeless lamp,
First, the film-shaped electrode 37 (roll-shaped wound body) is paid out, and is separated into the electrode member 32 and the separator 36 in the middle of the feeding. After this separation, the electrode member 32 is supplied to the glass tube 31 transport line, and is adhered to the outer peripheral surface of each glass tube. This attachment is performed on both connection terminals 3 of the electrode member 32.
In a state where 5 is positioned at one end of the glass tube, the operation is performed such that both strip-shaped aluminum electrodes 34 face each other. Thus, the electrodeless lamp is completed.

[0011]

However, the process of attaching the connection terminal 35 and the process of curing the thermosetting conductive adhesive in the process of manufacturing the film electrode 37 require a long working time, and the film-like electrode 37 requires a long working time. Electrode 3
7 occupies most of the manufacturing time. Therefore, the productivity of the film-shaped electrode 37 is low. Further, the connection terminals 34 and the conductive adhesive are expensive. As a result, the cost of manufacturing the film electrode 37 increases. Moreover, when one end of the transparent film 33 is peeled off, a streak-like fold is formed on the transparent film 33.

The film-like electrode 37 is wound into a roll as shown in FIG. 13 in consideration of easiness of storage and transportation. However, as shown in FIG. 14, the connection terminal 35 and the portion of the strip-shaped aluminum electrode 34 to which the connection terminal 35 is adhered are thicker than other portions, so that the thickness sandwiches the cushion material 43. Otherwise, the film electrode 37 cannot be neatly wound into a roll. For this reason,
It takes time and effort to wind up the film-like electrode 37 in a roll shape, and the manufacturing cost increases.

The summary of the

That is, in the film-like electrode of the present invention, the connection terminal and the strip-like electrode constituting the electrode member are integrally formed of the same material. Therefore, the step of attaching the connection terminals and the step of curing the thermosetting conductive adhesive, which occupy most of the production time of the film-like electrode, become unnecessary, and the production time of the film-like electrode is greatly shortened and the production volume is reduced. And an expensive connection terminal and the conductive adhesive are not required. As a result, there is an advantage that the manufacturing cost of the film electrode is reduced. In addition, there is no need to use an ear separator in the production process of the film-like electrode, and the transparent film does not have streak-like folds. In addition, since the connection terminal portion is as thin as the other portions, when the film-shaped electrode is formed into a roll shape, it can be formed into a clean roll shape without sandwiching a cushion material. For this reason, there is an advantage that a cushion material is not required, and costs for storage and transportation of the film electrode are reduced.

From the viewpoint of availability, an acrylic pressure-sensitive adhesive containing an acrylic ester-based copolymer as a main component is preferable. That is, since the acrylic pressure-sensitive adhesive is resistant to light and temperature changes, its adhesive strength does not decrease even when used for an electrodeless lamp, and excellent adhesive strength can be maintained for a long period of time.

In this embodiment, the film-shaped electrode 1 is arranged in parallel with a separator 7 made of a PET band-shaped sheet having one surface subjected to a release treatment, and on one surface of the separator 7 in a state perpendicular to the longitudinal direction. And a plurality of sets of electrode members 5. The electrode member 5 includes a transparent film 2 made of PET, and a pair of strip-shaped aluminum electrodes 4 with connection terminals arranged side by side on one surface of the transparent film 2. The transparent film 2 and the strip-shaped aluminum electrode 4 with both connection terminals are adhered by a film-side pressure-sensitive adhesive layer 3 (consisting of a silicone-based pressure-sensitive adhesive layer) formed on the entire surface of the transparent film 2. On the exposed surface of the strip-shaped aluminum electrode 4 with connection terminals (the surface opposite to the surface to which the transparent film 2 is adhered), an acrylic adhesive is applied to the exposed surface except for the tip of the connection terminal 4a to be described later. An electrode-applied pressure-sensitive adhesive layer 6 composed of a layer is formed. Then, utilizing the adhesive strength of the film-side adhesive layer 3 and the electrode-adhering adhesive layer 6,
Each electrode member 5 is detachably attached to one surface of the separator 7.

The strip-shaped aluminum electrode 4 with connection terminals is made of one piece of aluminum foil, and is formed from the top (one end) of the strip-shaped aluminum electrode portion 4b.
The connection terminal 4a formed in a rectangular shape (the connection terminal 4a
Is narrower than the aluminum electrode portion 4b). And the aluminum electrode part 4
b and the base end of the connection terminal 4a are adhered to one surface of the transparent film 2 via the film-side adhesive layer 3, and the connection terminal 4a
Of the transparent film 2 protrudes from the outer peripheral portion of the transparent film 2. In addition, the base ends of the aluminum electrode portion 4b and the connection terminal 4a are detachably attached to one surface of the separator 7 via the electrode sticking adhesive layer 6 as described above.

The film-like electrode 1 can be manufactured, for example, as follows. That is, first, an acrylic adhesive is applied to a portion of one surface of the strip-shaped separator 7 other than a portion corresponding to the tip of the connection terminal 4a using a comma coater, a lip coater, a reverse coater, a fauten coater, a gravure coater, or the like. To form a pressure-sensitive adhesive layer 6 for electrode bonding, and a base material 9 (roll-shaped) for aluminum electrode obtained by dry laminating a belt-shaped aluminum sheet 8 on the surface of the pressure-sensitive adhesive layer 6 for electrode bonding. A winding body (see FIG. 3) is prepared. Next, as shown in FIG. 3, while the aluminum electrode base material 9 is being unwound in a belt shape, the aluminum sheet 8 on the surface is cut by a rotary cutter (not shown in FIG. 3) on the outer peripheral surface of the rotary cutter. (The cutter part of the shape corresponding to the aluminum electrode 4 with a terminal is formed.)
By then half-cut (shown cut portion by a dotted line L ₁₎ to express the connection terminal with strip aluminum electrode 4 of the electrode shape (strip shape in which the convex portion is projected from the one end portion).
At this time, the two rectangular aluminum electrodes 4 with connection terminals are arranged side by side at a predetermined interval. Also,
The connection terminals 4a are all formed so as to face in the same direction. Next, an unnecessary portion of the aluminum sheet 8 is sequentially peeled off by the unnecessary aluminum removing device 21 to form a pair of strip-shaped aluminum electrodes 4 with connection terminals. In this manner, a plurality of sets of strip-shaped aluminum electrodes 4 with connection terminals are obtained, and the film 10 with electrodes attached to the strip-shaped separator 7 via the pressure-sensitive adhesive layer 6 for electrode attachment is obtained, and is wound into a roll.
When the unnecessary aluminum portion is peeled off, the pressure-sensitive adhesive layer 6 for attaching the electrode at that portion is removed together with the unnecessary aluminum portion.

On the other hand, one side of the strip-shaped transparent film 2 is coated with a silicone-based pressure-sensitive adhesive by a comma coater, a lip coater, a reverse coater, a fauten coater, a gravure coater, or the like to form a film-side pressure-sensitive adhesive layer 3. A laminated film 11 is prepared (see FIG. 4). The width of the transparent film 2 is smaller than the width of the separator 7, and the tip of the connection terminal 4 a is projected from the outer peripheral portion of the transparent film 2. When the laminated film 11 is formed into a roll-shaped wound body for easy storage and transportation, a separator for protecting the adhesive layer is attached to the surface of the adhesive layer 3 on the film side, and the laminated film 11 is used at the time of use. The adhesive layer protective separator is peeled off.

Then, as shown in FIG. 4, the film with electrodes 10 and the laminated film 11 (both rolled bodies) are fed out and passed between the movable rollers 22 facing each other. The surface of the strip-shaped aluminum electrode 4 with the connection terminal provided thereon and the surface on which the film-side adhesive layer 3 of the laminated film 11 is formed are joined together. At this time, in the integrated film, the separator 7 side is kept flat.

Next, the transparent film 2 of the integrated film is covered with the transparent film 2 in such a manner that a pair of strip-shaped aluminum electrodes 4 with connection terminals are covered with the transparent film 2 for each set.
Nicking L ₂ by partly cutting apparatus 23. The cut L2 is _two between adjacent sets. After that, the unnecessary portion 2a of the transparent film 2 is removed to complete the film electrode 1. The film-like electrode 1 completed in this way is wound into a roll and supplied to a production line for an electrodeless lamp.

In the production line of the electrodeless lamp,
First, the film-shaped electrode 1 (roll-shaped wound body) is fed out, and in the middle of the feeding, the electrode member 5 and the separator 7 are separated.
And separated into After this separation, the electrode member 5 is supplied to a step of transporting a cylindrical glass tube (translucent cylindrical body) described later, and is adhered to the outer peripheral surface of the glass tube. This sticking is performed such that the two strip-shaped aluminum electrodes 4 with connection terminals of the electrode member 5 face each other with both connection terminals 4a positioned at one end of the glass tube. Will be Thus, the electrodeless lamp is completed.

The electrodeless lamp obtained in this way is shown in FIGS. In this device, a glass tube 1 in which both end openings are closed and a rare gas such as xenon is sealed in a hollow space.
5, a white fluorescent paint 16 applied to the inner peripheral surface of the glass tube 15, and the electrode member 5 adhered to the outer peripheral surface of the glass tube 15. The electrode member 5 is attached to the outer peripheral surface of the glass tube 15 in a state where the strip-shaped aluminum electrode 4 with connection terminals is inside and the outside is covered with the transparent film 2. In addition, a pair of strip-shaped aluminum electrodes 4 with connection terminals are disposed in opposition to each other in order to effectively excite the rare gas sealed in the glass tube 15 and increase the illuminance. And
Due to wiring considerations, both connection terminals 4a are connected to the glass tube 15
Is mounted in a state of being positioned at one end opening. Then, the fluorescent paint 16 is applied to the inner peripheral surface of the glass tube 15 with only one of the gaps formed between the strip-shaped aluminum electrodes 4 having both connection terminals provided therebetween. Thereby, the illuminance is improved. In the figure, reference numeral 18 denotes a connection cord, and 19 denotes an insulating resin for ensuring insulation between both connection terminals 4a. In addition,
When the electrodeless lamp is used, a cap (not shown) is fitted to one end of the glass tube 15 so as to cover both connection terminals 4a, and the cap is filled with the insulating resin 19. It has become.

According to the film-shaped electrode of this embodiment, the strip-shaped aluminum electrode with connection terminal 4 is made of one piece of aluminum foil, and the connection terminal 4a and the aluminum electrode portion 4b are integrally formed of the same material. Since it is formed, the step of attaching the connection terminal 35 and the step of curing the thermosetting conductive adhesive, which are necessary in the conventional example, and occupy most of the manufacturing time of the film-like electrode 37, are not required. The production time of the film-shaped electrode 1 can be greatly shortened and the production amount can be increased, and expensive connection terminals and the conductive adhesive are not required. As a result, the manufacturing cost of the film electrode 1 is reduced. Further, the folds of the transparent film 33 that have occurred in the related art are eliminated. Further, since the connection terminal 4a is as thin as the aluminum electrode portion 4b, when the film electrode 1 is formed into a roll shape,
A beautiful roll shape can be obtained without sandwiching the cushion material. For this reason, a cushion material becomes unnecessary, and the cost of storage and transportation of the film-shaped electrode 1 is reduced.

The material of the transparent film 2 is P
Since ET is used, coloring and discoloration do not occur even when an electrodeless lamp is used. Further, since the width of the transparent film 2 is smaller than the width of the separator 7, the film-side pressure-sensitive adhesive layer 3 does not adhere to the movable roller 22 or other rollers.

The film-side pressure-sensitive adhesive layer 3 has a siloxane bond [-(SiO) n-] because a silicone pressure-sensitive adhesive is used as a material for forming the film-side pressure-sensitive adhesive layer 3. Excellent in heat resistance, water repellency, electrical insulation (high volume resistivity), chemical resistance and aging resistance. In addition, since this silicone-based pressure-sensitive adhesive is resistant to light and temperature changes, even when used in an electrodeless lamp, its pressure-sensitive adhesive strength is not reduced, and excellent pressure-sensitive adhesive strength can be maintained for a long period of time.

Further, since an acrylic pressure-sensitive adhesive is used as a material for forming the pressure-sensitive adhesive layer 6 for attaching the electrode, the electrode member 5 can be firmly bonded to the glass tube 15 of the electrodeless lamp, and can be obtained at low cost. In addition, since the acrylic pressure-sensitive adhesive is resistant to light and temperature changes, its adhesive strength does not decrease even when used in an electrodeless lamp, and excellent adhesive strength can be maintained for a long period of time.

According to the method of manufacturing a film electrode of this embodiment, the aluminum sheet 8 adhered to one surface of the separator 7 is half-cut by a rotary cutter, so that the manufacturing time of the film electrode 1 is extremely short. And the production can be increased.

[0043] Further, the number of cuts L ₂ Add a transparent film 2 of the integrated film are the two among the pairs adjacent to each other, a gap portion between the two cuts L ₂ is formed The gap facilitates the mechanical separation of the electrode member 5 and the separator 7 in the electrodeless lamp production line.

According to the electrodeless lamp of this embodiment, the production cost can be increased and the production cost is low. Since the electrode member 5 of the film electrode 1 is used, the production cost is low. Become.

FIGS. 7A to 7C show another embodiment of the film electrode 1 of the present invention. In this embodiment, another aluminum sheet piece 12 is adhered to the top surface of the connection terminal 4a and the aluminum electrode portion 4b of the above embodiment.
a and the top of the aluminum electrode portion 4b have a two-layer structure. The other parts are the same as in the above embodiment.

Also in this embodiment, the film-shaped electrode 1 is manufactured by dry laminating a strip-shaped aluminum sheet 8 on one surface of a strip-shaped separator 7 in the same manner as in the above-described embodiment. An aluminum tape having a pressure-sensitive adhesive layer formed on the back surface is adhered to the surface of the terminal (the end on which the terminal 4a is formed) to prepare a base material for an aluminum electrode with an aluminum tape. Then, the aluminum sheet with the aluminum tape on the surface is half-cut into a predetermined shape by a rotary cutter while the base material for the aluminum electrode with the aluminum tape is unwound in a strip shape, and the aluminum sheet piece is placed on the top of the connection terminal 4a and the aluminum electrode portion 4b. Thus, the electrode member 5 to which the electrode 12 is attached is obtained. The subsequent steps are performed in the same manner as in the above embodiment.
