Description

  The present invention relates to various types of control circuit boards installed in gaming machines such as pachinko machines, slot machines, and pachislot machines, and to protective covers that are coated to protect the control circuit boards.

  The protective cover for protecting the control circuit board, in particular the control circuit board protective cover used in pachinko machines, etc., is made of transparent synthetic resin so that the control circuit board can be seen from the outside. ing. At the same time, the control circuit board covered with the protective cover is a defined board, and the person who is the manufacturer and the control number can be identified immediately. Is marked with an identification.

This identification display is obligatory and is generally performed by pasting a display sheet made of paper or a synthetic resin sheet. As described above, this display sheet is usually attached to an easily visible portion of the front surface portion of the protective cover with an adhesive.
The sticking of the seal may be obligatory and is extremely common, and needless to say, for example, as disclosed in Japanese Patent Application Laid-Open No. 11-76561.
Japanese Patent Laid-Open No. 11-76561, claim 1 in claims, paragraphs 0009, 0010, 0012, 0017 of the specification, and FIGS. 1 and 4 of the drawings.

In this way, the protective cover of the control circuit board in the gaming machine is attached with a display sticker as an identification display. However, when the gaming machine is discarded, the control circuit board that is also discarded is recycled. When rotated, there was a problem that the seal attached to the protective cover hinders reuse.
In other words, the protective cover of the control circuit board to be disposed of is removed from the board, and then reused for pulverization and recovered as a resource. At this time, it is necessary to remove the display seal from removing impurities. There is. This display sheet is firmly bonded to prevent unauthorized replacement during use, that is, to prevent unauthorized actions due to display changes due to replacement, and therefore cannot be easily peeled off. It has become a thing.

  Conventionally, in such a situation, a great deal of effort has been taken to remove the seal, but since it is strongly bonded, it cannot be completely removed, There was a problem that the adhesive used for adhesion remained on the protective cover and this was mixed into the synthetic resin during resource recovery, resulting in deterioration of its physical properties and quality.

  The present invention has been developed to improve the above problems in view of the problems associated with the identification display for the conventional protective cover described above, that is, the problems at the time of resource recovery resulting from the display method by attaching the display sticker. It is.

  As is apparent from the above, the display seal on the conventional protective cover is firmly bonded with a strong adhesive, making it difficult to peel off, leaving a part of it or leaving the adhesive attached. Thus, when recovering the used synthetic resin, these are mixed as impurities, which deteriorates the physical properties and quality of the synthetic resin. Therefore, in the present invention, a display seal used for identification display from the protective cover is provided. In addition to improving the efficiency of recycling work, it is possible to easily and surely remove other identification items at the beginning, and to prevent the contamination of impurities and maintain the physical properties and quality of the recovered synthetic resin. It is an object of the present invention to provide an improved protective cover for a control circuit board so that it can be used.

  In order to achieve the above-mentioned object, the present invention provides a protective cover made of synthetic resin for covering a control circuit board, wherein a trapezoidal display raised portion protruding from the surface portion is formed on the front surface portion of the protective cover. In addition, a display sticker, a print for identification display, or a display body for identification display such as an ID chip on which the identification display is recorded is pasted or embedded on the upper surface of the raised portion. It is in.

  The protective cover is formed of a transparent synthetic resin as described above, and is formed in a shallow box shape so as to cover the entire surface of the control circuit board having a plate shape, and faces the surface of the substrate. The display raised portion is formed on the front surface portion.

The display raised portion is integrally formed when the protective cover is formed. And this display protruding part is formed in the shape of a table | surface in the state which protruded from the front surface part of the protective cover, and forms the upper surface in the area which can attach display bodies, such as a display sticker.
When the display body is flat like a display sticker, the entire surface is smooth so that it can be clearly displayed. In the case of a display body such as an ID chip, the chip is embedded at a height that can be embedded. Will do.

  By the way, the height of the display raised portion is, as will be described later, when removing the display attached to the upper surface of this raised portion, only the upper surface portion of the display raised portion, that is, the surface layer portion, without the cutting cutter scraping off the front surface portion. As long as the height that can be scraped off is ensured, it is not necessary to be higher.

  In other words, the height of the display raised portion is a height for preventing the cutter blade edge from coming into contact with the front surface portion and scraping off the protective cover main body during the cutting operation by the cutter. When moving along the front surface portion in parallel, it is only necessary to secure a height at which only the upper surface portion of the display raised portion, that is, the surface layer portion to which the display body such as the display sticker is fixed can be scraped off.

  The display raised portion thus formed has a flat upper surface, which facilitates sticking of the display sticker, and along the peripheral portion of the upper face to prevent peeling of the attached display sticker. Forming a surrounding projection and preventing the display seal from being peeled off from the peripheral edge by an external force.

  It is desirable that the surrounding protrusions have a height that preferably exceeds the thickness of the display sticker to be attached, but even if the height is equal to the thickness or slightly raised from the upper surface, it works effectively. It will be.

  The surrounding protrusions are preferably continuous ridges along the peripheral edge of the upper surface, but even if they are discontinuous, they receive external forces due to contact or collision of objects and act directly on the peripheral edge of the display sheet. It is effective in avoiding the problem.

  The protective cover of the present invention configured as described above is a method of identifying and displaying on the upper surface by printing with ink, in addition to displaying the display sticker on the upper surface of the display ridge formed on the front surface portion thereof, Alternatively, it is possible to display by pasting or embedding an ID chip on which identification information is recorded, and these display bodies are cut off from the protective cover in the same manner as the display seal by cutting the display ridges along the upper surface. Can be removed.

  By the way, in the present invention, when a display body such as a display sheet is removed from the protective cover, it is cut by a cutter and removed together with a part of the material. In this case, the cutter used is the upper surface layer portion of the display raised portion. In this case, it may be thinly scraped, and therefore the type and shape of the cutter are not specified.

In addition, a rotary cutter having a cutting blade on the peripheral surface is suitable as a cutter for cutting and removing more efficiently.
The rotation axis of the rotary cutter is supported horizontally, the protective cover is moved in the direction perpendicular to the rotation axis below, and the upper surface of the display ridge raised on the front surface is the peripheral surface of the cutter If the contact is made, the upper surface portion can be peeled off thinly in parallel with the front surface portion by the rotating blade edge, and the material is not scraped off more than necessary and is not wasted.

  And in this case, a guide stand that guides the protective cover in a direction perpendicular to the rotation axis of the rotary cutter on the bed that is horizontally supported, and if the protective cover is fed into the guide, It is possible to continuously remove the upper surface portion of the display raised portion, and a rapid processing operation can be expected.

  Since the present invention is configured as described above, it is not necessary to peel off the display sheet to be attached to the surface of the protective cover. Therefore, the display sheet can be attached with a strong adhesive, but this is not necessary when removing the display sheet. Since it can be removed from the protective cover without being influenced by the adhesive strength of the adhesive and without leaving the adhesive, impurities can be mixed in when recovering the synthetic resin used when the protective cover is disposed of. The synthetic resin used can be recovered in a state with high physical properties and quality.

  Further, the protective cover of the present invention is attached to the inside of the upper surface surrounded by the protrusion even when it is on the upper surface of the raised display protrusion when the surrounding protrusion is raised along the peripheral edge of the upper surface of the display protrusion. Even if an external force from the side is applied to the display body such as a display sticker, the display sticker is protected by the protrusions, so that it is not peeled off from the edge of the seal and a stable fixed state can be obtained.

Of course, the protective cover according to the present invention is easy to scrape with the cutter as described above because the display raised portion is lifted from the front surface portion of the protective cover when the display body is removed. There is an advantage that impurities can be removed continuously reliably and quickly.
Next, an embodiment of the protective cover according to the present invention will be described, and the features thereof will be clarified.

FIG. 1 is a schematic perspective view of a protective cover according to the present invention, and FIG. 2 is a central longitudinal front view of FIG.
The protective cover 1 covers a game control circuit board (not shown) for controlling a game provided on the back of the pachinko gaming machine, and forms a circuit box in cooperation with a lower cover (not shown). In this case, the game control circuit board is housed and protected.

  As described above, the protective cover 1 is formed into a plate shape by forming a synthetic resin material having light permeability so that the internal game control circuit board can be visually recognized from the outside, in this case, polycarbonate in a box shape. The opening is closed by tying with the lower cover, and the game control circuit board inserted between the two is enclosed and sealed, and the protective cover 1 (here, the upper cover for the lower cover). The surface of the game control circuit board can be seen through the front surface portion 1a.

In the figure, reference numerals 2 and 3 denote large and small display raised portions formed so as to protrude from the front surface portion 1a of the protective cover 1 and to be raised.
The display raised portions 2 and 3 are game control circuit boards (in this case, game control circuit boards that are required to be displayed on the protective cover 1, but they are main body control circuit boards or other circuit boards. The display sticker for displaying the model name of the pachinko gaming machine is displayed on the large display raised portion 2 and a small display. A display seal 5 with a management number for managing the game control circuit board used in the pachinko gaming machine so that the game control circuit board used in the pachinko gaming machine is not illegally changed, changed, or modified is provided on the raised portion 3. It is pasted.

The two display raised portions 2 and 3 are integrally formed so as to protrude from the front surface portion 1a when the protective cover 1 is formed. These display ridges are formed in such a size that the upper surfaces 2a and 3a are aligned with the display seals 4 and 5 and can be attached.
These display raised portions 2 and 3 are formed at an arbitrary height from the front surface portion 1a, but when the surface is raised with a cutter as will be described later, the display raised portions 2 and 3 are not cut away. It is sufficient that the upper surface portion, that is, the display portion can be scraped off, and it is sufficient if it is formed to a height of 2 to 3 mm from the viewpoint of material saving.

The display seals 4 and 5 are bonded and fixed to the display raised portions 2 and 3 through an adhesive 6 so as to be integrated.
In addition, as shown in the figure, the upper surface 2a of the display raised portion is not attached to the display seal 4 to be attached to the upper surface 2a, and is attached so as to cover almost the entire surface. This is due to the material saving of the display ridge as in the selection of the height, and it is desirable to form the display ridge as small as possible in accordance with the size of the display seal.

  FIG. 3 shows another example in which a protrusion 7 is raised along the peripheral edge of the upper surface 2a of the display raised portion 2 that is raised from the front surface portion 1a of the protective cover 1 and surrounds the peripheral edge of the display seal 4 that is pasted on the upper surface. This embodiment is shown. The protrusion 7 prevents the edge of the display seal 4 from being turned up, and prevents unauthorized replacement or concealment of the origin of the manufacturer or the like by stripping and illegal disposal.

  In the present embodiment, an example in which the display stickers 4 and 5 are used as display bodies will be described. However, as a display method, a method of directly printing using ink on the upper surfaces 2a and 3a instead of the display stickers, or an ID chip is attached. In some cases, the display stickers may be attached or buried, and at this time, these display bodies are provided at positions that are lifted from the front surface portion 1a of the protective cover.

FIGS. 4 and 5 show the operation of removing the display body after the use of the protective cover 1 is finished and the work is recycled.
In the drawing, 8 is a working bed, and 9 is a cutter device installed above the bed 8.
The bed 8 horizontally supports the protective cover 1 with the front surface portion 1a facing upward, and passes through two guide frames 10 and 10 attached in parallel with a front-rear interval on the bed 8 from right to left (arrow direction). It can be moved to.

  The cutter device 9 is located immediately above the two guide frames 10 and 10 and supports a rotary blade 12 having a large number of cutting blades 11 on the peripheral surface thereof by horizontally supporting the rotary shaft 13 thereof, thereby providing a front surface portion of the protective cover. 1a, that is, in this drawing, can be placed on the upper surface.

The cutter device 9 is supported so as to be freely slidable in a vertical direction with respect to a support column 16 that vertically mounts a case 15 that houses a motor 14, and a bearing arm 17 that is suspended in parallel with the front and rear of the case 15. The rotary shafts 13 at both ends of the rotary blade 12 are rotatably mounted. A pulley 18 is provided at a shaft end protruding rearward, and a belt 21 is stretched between the pulley 14 and a drive pulley 20 provided on the drive shaft 19 of the motor 14 so that the rotary blade 12 can be rotated by the motor 14.
In addition, it is advantageous in terms of work efficiency if the dimension in the width direction of the rotary blade 12 is set larger than the width dimension of the raised portions 2 and 3 and can be completed by a single cutting operation.

The cutter device 9 is prepared to quickly and surely remove the display body from the protective cover 1, and in the operation, the protective cover 1 is horizontally placed on the bed 8 as shown in the drawing, and the front and rear guide frames are provided. 10 and 10 are guided to the bottom of the cutter device 9.
At this time, the height of the case 15 is adjusted so that the lower edge of the rotary blade 12 is supported at a height at which the lower edge of the rotary blade 12 comes into contact with the surface layer portion of the display raised portion 2 (or 3). The display raised portion 2 is cut off together with the upper surface portion thereof and the display body provided thereon, that is, the display seal 4.

  Since the scraping by this cutter is only the surface layer portion of the display raised portion 2 protruding from the upper surface 1a of the protective cover 1, only a small amount of the synthetic resin material is scraped off together with the display body. The display body, that is, the display seal 4 is completely removed from the protective cover together with the adhesive 6, so that these impurities are not mixed in the subsequent recovery process, and the used synthetic resin can be recovered as it is. It will be possible.

  When the protective cover 1 is moved horizontally along the upper surface of the bed 8 one after another in the scraping operation of the display body and fed, the surface layer portion of each display raised portion 2 at the same height is scraped by the rotary blade 12. As a result, only the portion to which the display body adheres is scraped off during continuous work, so that waste of material is avoided and the load on the cutter device is reduced, so that work can be performed efficiently.

  Here, the case where the display sticker 4 is bonded to the display raised portion 2 as a display body using the adhesive 6 is described. However, instead of this display sticker, the upper surface 2a is printed with ink and displayed. Even when the ID chip is affixed or embedded, it can also be removed from the protective cover by the scraping operation by the cutter device 9.

  By the way, in the case where a plurality of display bulges are formed on the upper surface of the protective cover as shown in the above description such that two display bulges are bulged, the heights thereof are aligned and the moving direction during cutting If it arrange | positions so that it may arrange | position to, the cutting by the said cutter apparatus can be completed by one operation, and it is convenient.

  Further, in the present embodiment, the cutter device is used as the rotary blade 12, but it may be a single blade as long as the surface layer portion of the display raised portion is scraped off. May be of a grinder type, and its type and model are not specified.
