Electronic device, gaming device, and method of manufacturing electronic device

Technical field

[0001] The present invention relates to an electronic device (for example, a gaming device) including a display device and a method for manufacturing the same.

Background art

[0002] Recent gaming devices (electronic devices) such as pachinko machines and slot machines have a display device for effect display in order to enhance the fun of the game. When the display device that is powerful is a liquid crystal display device, a glass substrate (referred to as a TFT substrate) including a TFT (Thin Film Transistor) and a glass substrate (referred to as a CF substrate) including a color filter (Color Filter) are used. A liquid crystal display panel with a liquid crystal in between is included.

[0003] Such a liquid crystal display panel is vulnerable to impacts, and in particular, polarizing plates attached to both surfaces (front and back surfaces) of the liquid crystal display panel are easily damaged. And the crack which arose in the polarizing plate or the liquid crystal display panel deteriorates the display performance of a liquid crystal display device. Therefore, a gaming device such as Patent Document 1 has a protective cover for protecting the liquid crystal display panel.

[0004] An example of the protective cover is shown in the cross-sectional view of FIG. 14A. As shown in FIG. 14A, a protective cover 102 for protecting the display surface of the liquid crystal display device 101 is attached to the casing 104 of the gaming device 149 that accommodates the liquid crystal display device 101 and the bezel 103 that holds the liquid crystal display device 101. ing. Therefore, the liquid crystal display device 101 after being attached to the housing 104 is sufficiently protected by the protective cover 102.

Patent Document 1: JP 2004-298542 A (see FIG. 4)

Disclosure of the invention

Problems to be solved by the invention

However, in the case of the gaming device 149 as shown in FIG. 14A, the liquid crystal display device 101 before being attached to the housing 104 is not protected by the protective cover 102. Therefore, the liquid crystal display panel 119 may be damaged in the process of attaching the liquid crystal display device 101 to the housing 104. Therefore, as shown in FIG. 14B and FIG. A protective cover (temporary protective cover 150) that temporarily protects the liquid crystal display panel 119 is attached to the display device 101 on the bezel 103 via a force tape 151 (FIG. 14B shows a single-sided tape 15 la). Figure 14C shows a 15 lb double sided tape).

[0006] However, attaching such a temporary protective cover 150 to the bezel 103 via the tape 151 not only hinders efficiency in the manufacturing process of the gaming machine, but also increases the cost of the gaming machine 149. Will also be connected.

The present invention has been made to solve the above problems. The object of the present invention is to provide an electronic device (for example, a gaming device) capable of protecting the display surface of the display device in the manufacturing process while being efficiently and inexpensively manufactured, and a method for manufacturing such an electronic device. Is to provide.

Means for solving the problem

[0008] The present invention includes a housing that houses a display device, a frame that holds the display device, and a protective cover that protects the display surface of the display device, and the protective cover is attached to the frame. This is an electronic device that includes an appendix.

[0009] When such an attachment portion is provided, for example, on a frame, a protective cover is further attached to the frame holding the display device. Therefore, these can be handled as one module (display module). In addition, the display module always protects the display surface of the display device with a protective cover. Therefore, even when both are in contact with each other when the display module is attached to the housing, the display surface of the liquid crystal display device and the housing cannot be in direct contact with each other by the protective cover.

[0010] It should be noted that the effect of avoiding contact between the display surface of the liquid crystal display device and the housing is obtained by the above-described method for manufacturing an electronic device, that is, the display device and a frame body that holds the display device. The manufacturing method of the electronic device including the protective cover for protecting the display surface of the display device and the housing for housing the protective cover includes a protective cover attaching step for attaching the protective cover to the frame body. It can be said that the effect is brought about.

More specifically, in the method for manufacturing an electronic device, a protective cover attaching step, a display device holding step for holding the display device on the frame, and the display device, the frame, and the protective cover are accommodated in the casing. If the housing housing process is included, the maintenance is performed before the housing housing process. When the protective cover attaching process and the display device holding process are completed, it is desired. If this is the case, the display module is attached to the housing, and the display surface of the display device and the housing can be reliably prevented from contacting each other.

[0012] By the way, the attachment portion is provided in a facing portion which is a part of the frame body positioned on the display surface side when the display device is held by the frame body. Further, it is desirable that the facing facing portion has a thickness that separates the protective cover and the display surface. If this is the case, a gap (clearance) is created between the protective cover and the display surface, preventing contact between the protective cover and the display surface.

[0013] In addition, the shape of the mounting portion is not limited. For example, the attachment portion may have a groove that is attached to the frame body by inserting a protective cover. And if it is an attaching part which has such a groove | channel, it will become possible to attach or detach the protective cover to a frame body according to the slide of a protective cover by utilizing a groove | channel. For this reason, it is easy to replace the protective cover for powerful electronic devices.

[0014] When the protective cover is inserted into the groove, the mouth portion of the groove into which the protective cover first enters is the inlet, and the mouth portion of the groove facing the inlet is the outlet. Then, the gap between the protective cover thickness direction at the inlet and the gap between the protective cover thickness direction at the outlet is the gap between the protective cover thickness direction at the inlet longer than the protective cover thickness. It is preferable that the distance is longer than the interval of sandwiching the thickness direction of the protective cover at the outlet. In this way, there is a margin at the entrance of the groove, and the protective cover can be easily inserted into the groove.

[0015] Further, the length of the opposing grooves in which the length connecting the inlets in the opposing grooves and the length connecting the outlets in the opposing grooves is longer than the length of the protective cover sandwiched between the opposing grooves. The length connecting the inlets should be longer than the length connecting the outlets in the opposite grooves. Even in this case, there is a margin at the entrance of the groove, and the protective cover can be easily inserted into the groove.

[0016] As an example of a groove in which the length connecting the inlets in the opposing grooves is longer than the length connecting the outlets in the opposing grooves, the groove depth of the inlet is greater than the groove depth of the outlet. The groove is also long. [0017] Also, when the protective cover is inserted into the groove, a first ridge that makes point contact or line contact with the protective cover or a first sliding material that slides the protective cover is provided at a location that contacts the protective cover. It is desirable. The protective cover is preferably provided with a second ridge that makes point contact or line contact with the contact object, or a second sliding member that slides the protection cover itself with respect to the contact object. If these are the case, the protective cover moves smoothly between the grooves.

[0018] It should be noted that the above-mentioned contact portion and the above-described contact object are preferably the inner surface of the groove or one surface of the facing portion provided with the attachment portion.

[0019] In addition, it is desirable that the electronic device includes a drop-off prevention unit that prevents the frame cover from falling off. And it is desirable for this drop-off prevention part to stop the movement of a protective cover, for example by engaging with the protective cover attached to the frame. In this way, the protective cover cannot be removed from the completed display module, and the display module securely protected by the protective cover can be attached to the chassis.

[0020] Note that the drop-off prevention unit separates from the protective cover when the protective cover is attached to the frame and when the protective cover is released from the frame, and the protective cover is attached to the frame. In the case of the first wearing, it is desirable that it comes into contact with the protective cover. This makes it easy to attach and remove the protective cover

[0021] There are various electronic devices as described above. As an example, there is a gaming device (for example, a slot machine or a pachinko machine).

The invention's effect

According to the present invention, the protective cover that protects the display surface of the display device is attached to the frame that holds the display device. Therefore, a module consisting of a display device, a protective cover, and a frame (referred to as a display module) is completed and can be handled in units of the display module.

[0023] Then, in the manufacturing process of the electronic device, the display module whose display surface is protected by the protective cover is attached to the casing. Therefore, contact between the display surface and the housing is avoided by the protective cover. In addition, a member that temporarily protects the display surface (temporary protective cover, etc.) Is no longer necessary, and electronic equipment can be manufactured inexpensively and efficiently.

BEST MODE FOR CARRYING OUT THE INVENTION

[Embodiment 1]

An embodiment of the present invention will be described below with reference to the drawings. Note that, for the sake of convenience, depending on the drawing, the member number or the like may be omitted. [0027] [1. Pachinko machine]

A gaming machine such as a slot machine or a pachinko machine can be said to be an electronic device. Hereinafter, a pachinko machine as shown in FIG. 13 will be described as an example of an electronic device. FIG. 1 shows a partial cross section of the pachinko machine 49 shown in FIG. As shown in FIG. 1, the pachinko machine 4 9 includes a liquid crystal display device (display device) 1 that displays information required for a game, a protective cover 2 that protects the liquid crystal display panel 19 of the liquid crystal display device 1, and a liquid crystal display. It has a bezel 3 for holding the device 1 and a housing 4 for mounting them.

[0028] [1 1. Liquid crystal display]

The liquid crystal display device 1 includes a liquid crystal display panel 19, a backlight unit 29, and a frame 39 on which the liquid crystal display panel 19 is mounted.

In the liquid crystal display panel 19, the active matrix substrate 11 and the counter substrate 12 facing the active matrix substrate 11 are bonded together with a sealing material (not shown), and liquid crystal (not shown) is injected between these gaps. Has been. Further, polarizing plates 13 and 13 for sandwiching the active matrix substrate 11 and the counter substrate 12 may be provided. The liquid crystal display panel 19 functions as a display panel by receiving light (planar light) from the knock light unit 29.

On the other hand, the backlight unit 29 emits light (backlight light) toward the liquid crystal display panel 19. The knock light unit 29 includes a cathode ray tube 21, a reflector 22, a light guide plate 23, a reflection sheet 24, and an optical sheet 25.

The cathode ray tube 21 emits light, and part of the light is directly incident on the outer peripheral end of the light guide plate 23. The reflector 22 guides the remaining light that is not directly incident on the outer peripheral end of the light guide plate 23 to the outer peripheral end of the light guide plate 23 by reflecting it. The light guide plate 23 converts the direct light (linear light) from the cathode ray tube 21 or the light from the cathode ray tube 21 via the reflector 22 into planar light.

[0032] The reflection sheet 24 reflects the light from the cathode ray tube 21 and the light propagating through the light guide plate 23 toward the liquid crystal display panel 19 without leaking, and the optical sheet 25 is a light guide plate. The light from 23 is diffused and spread over the entire liquid crystal display panel 19. [0033] [1 2. Protective cover]

The protective cover 2 is a light transmissive plate having an area that can cover the display surface E of the liquid crystal display device 1. The protective cover 2 protects the liquid crystal display device 1, particularly the counter substrate 12 and the polarizing plate 13 of the liquid crystal display panel 19 from an impact cover. For this reason, the protective cover 1 must be made of a material having a certain level of strength. For example, polycarbonate (Poly carbonate; PC), polymethylol methacrylate (Polymethyl methacrylate; PMMA), glass, or the like is suitable for the protective cover 2. In consideration of the convenience of handling, the thickness of the protective cover 2 is preferably about 0.3 to 5 mm.

[0034] [1-3. Bezel]

As shown in FIG. 1 and FIG. 2, the bezel (frame body) 3 covers and surrounds the periphery of the display surface E of the liquid crystal display device 1 and the outer peripheral edge of the liquid crystal display device 1. Holding. Therefore, as shown in FIG. 1, the bezel 3 includes a facing portion 3 a located on the periphery of the liquid crystal display device 1 on the display surface side, and a side surface portion 3 b located on the outer peripheral end side of the liquid crystal display device 1. Yes.

Further, the bezel 3 is provided with a mounting portion 5 for attaching the protective cover 2 to the bezel 3 itself. For example, as shown in FIG. 3 (partially enlarged view of FIG. 2), a plurality of attachment portions 5 are provided on the facing portion 3a located on the periphery of the display surface E of the liquid crystal display device 1.

[0036] Then, as shown in Fig. 1, the mounting portion 5 is connected to the support piece 5a that protrudes from the surface of the facing portion 3a (one surface of the facing portion) 3aa, and the supporting piece 5a, and the protective cover 2 And a holding piece 5b for holding down. Then, a groove G is formed by the pressing piece 5b, the supporting piece 5a, and the surface 3aa of the facing portion 3a. Therefore, the protective cover 2 is fixed to the bezel 3 by sandwiching the protective cover 2 in the groove G. That is, the protective cover 2 is attached to the bezel 3 by being inserted into the groove G.

[0037] In the above description, the force that causes the groove G to be generated between the support piece 5a and the pressing piece 5b of the attachment portion 5 and the surface 3aa of the facing portion 3a is not limited to this. For example, the groove G may be carved in the mounting part 5 itself as shown in FIG. 4, or the groove G itself carved in the facing part 3a may be the mounting part 5 as shown in FIG. . In short, the part that creates or has the groove G is the mounting part 5. [0038] The number of the attachment portions 5 may be singular or plural. As an example of the plurality of mounting portions 5, as shown in FIG. 6, two facing portions 3a '3a constituting the long side of the bezel 3 and two facing portions constituting the short side of the bezel 3 A plurality of mounting portions 5 are provided on one of the 3a, and the extending direction of the pressing pieces 5b in each mounting portion 5 (the extending direction of the pressing pieces 5b extending from the support piece 5a) is a bezel. You can list the ones that face the inside of 3.

[0039] In this manner, the protective cover 2 is provided with the mounting portion 5, and is slid through the facing portion 3a constituting the short side, and is generated by the installation of the mounting portion 5. {The white arrow in Fig. 6 indicates the sliding direction (however, the insertion direction); the same applies to Fig. 7, Fig. 9 and Fig. 12}). As a result, three of the four sides at the periphery of the protective cover 2 are fixed by the groove G, and the protective cover 2 is attached to the bezel 3. However, if the protective cover 2 slides in the direction opposite to the slide insertion, the strong protective cover 2 will release the groove G force. Therefore, the groove G makes it possible to attach / detach the protective cover 2 to / from the bezel 3! /.

[0040] [1-4. Case]

The casing 4 is not particularly limited as long as it can accommodate the liquid crystal display device 1, the bezel 3, and the protective cover 2. Further, the material of the housing 4 is not particularly limited, and the resin may be a metal.

[0041] [2. Summary]

In the pachinko machine 49 as described above, the mounting portion 5 for attaching the protective cover 2 is included in the bezel 3 that holds the liquid crystal display device 1. Therefore, the manufacturing process of the pachinko machine 49 includes a protective cover attaching step of attaching the protective cover 2 to the bezel 3 itself using the attaching portion 5.

In this manner, the liquid crystal display device 1 is held by the bezel 3 to which the protective cover 2 is attached via the attachment portion 5. Then, when the liquid crystal display device 1 (display module; see later) is housed in the housing 4 (in the housing housing process), the housing 4 and the display surface E of the liquid crystal display device 1 are likely to come into contact with each other. Even so, the protective cover 2 protects the display surface E. Therefore, damage to the display surface E in the liquid crystal display device 1 is suppressed.

[0043] It should be noted that the damage suppression effect includes a protective cover attaching step, a display device holding step for holding the liquid crystal display device 1 on the bezel 3, and a liquid crystal display device 1, bezel 3, and In the manufacturing process of the pachinko machine 49 including the housing housing process for housing the protective cover 2, the protective cover mounting process and the display device holding process are completed before the housing housing process. It can also be said to be an effect resulting from this.

[0044] If a module including the liquid crystal display device 1, the bezel 3, and the protective cover 2 completed after the protective cover attaching step and the display device holding step is a display module, the display module is a powerful display module. The included protective cover 2 can be used for the pachinko machine 49 that is the final product.

[0045] Therefore, during the manufacturing process of the pachinko machine 49, a separate member for temporarily protecting the display surface E is not necessary. In other words, when the display module is attached to the housing 4, there is already a protective cover 2 that protects the display surface E, so that a separate member becomes unnecessary. Therefore, since there is no process for attaching another component to the display surface E, the manufacturing process of the pachinko machine 49 can be made more efficient. Moreover, since no separate member is required, the cost of the pachinko machine 49 can be reduced.

[0046] Further, when the liquid crystal display device 1 is held by the bezel 3, the mounting portion 5 is a facing portion 3a that is a part of the bezel 3 positioned on the display surface side (more specifically, the surface of the facing portion 3a 3aa). Further, the facing portion 3a that is applied has a certain thickness.

[0047] With this configuration, when the protective cover 2 is attached to the facing portion 3a via the mounting portion 5, the protective cover 2 is positioned on the surface 3aa of the facing portion 3a. Therefore, an interval (clearance) corresponding to at least the thickness of the facing portion 3a occurs between the protective cover 2 and the display surface E of the liquid crystal display device 1. Then, even if an impact is applied to the protective cover 2, the protective cover 2 and the display surface E of the liquid crystal display device 1 are difficult to directly contact with each other due to clearance.

In addition, the attachment portion 5 has a groove G that is attached to the bezel 3 by inserting the protective cover 2. Since there is a strong groove G, the protective cover 2 can be attached to and detached from the bezel 3 according to the slide of the protective cover 2. Therefore, if the protective cover 2 is damaged, the strong protective cover 2 can be freely replaced.

[0049] [Embodiment 2]

A second embodiment will be described. Note that members having the same functions as those used in Embodiment 1 are denoted by the same reference numerals, and description thereof is omitted. This implementation In the embodiment, the shape of the attachment portion 5 will be described in detail.

[0050] For example, as shown in FIG. 7A and FIG. 7B (a cross-sectional view taken along the line A—A ′ in FIG. 7A), when the protective force bar 2 is slid into the groove G, the protective cover 2 is The mouth portion of the groove G that enters first is the entrance G, while the mouth portion of the groove G that faces the entrance G is the exit G.

[Embodiment 3]

Embodiment 3 will be described. Note that members having the same functions as those used in Embodiments 1 and 2 are denoted by the same reference numerals and description thereof is omitted. In this embodiment, the device for realizing the smooth movement of the protective cover 2 in the groove G will be described in detail.

[0059] For example, as shown in FIG. 10, when the protective cover 2 is inserted into the groove G, the ridge (first bulge) P that makes point contact or line contact with the protective cover 2 to be covered is the facing portion 3a. It is desirable to be provided on the surface 3aa. However, the installation location of the prominent ridge P is not limited to the surface 3aa of the facing portion 3a, and may be provided inside the groove G, for example. In short, if the protective cover 2 is inserted into the groove G, it is sufficient if the first ridge P is present at the place where it comes into contact with the strong protective cover 2.

[0060] In this manner, the contact area between the first ridge P and the protective cover 2 is the same as that of the groove G itself. It is narrower than the contact area with the cover 2 (area of surface contact). As a result, the frictional resistance is lowered due to the narrow contact area, and the protective cover 2 is easily inserted into the groove G.

[0061] To slide the protective cover 2, a member (first sliding) having a relatively low friction coefficient as shown in Fig. 11 is formed on the surface 3aa of the facing portion 3a in contact with the protective cover 2 or on the inner side of the groove G. Material) Q may be provided. Even if this is the case, the protective cover 2 can easily be inserted into the groove G.

[0062] In addition, the installation location of a member that facilitates insertion of the protective cover 2 into the groove G, such as the first ridge P or the first sliding material Q, is limited to the surface 3aa of the facing portion 3a or the inside of the groove G. It will not be done. For example, the protective cover 2 itself may be provided with a member that facilitates insertion into the groove G.

[0063] That is, the protective cover 2 itself has a bulge (second bulge; not shown) that makes point contact or line contact with the surface 3aa of the facing portion 3a or the inside of the groove G (referred to as a contact object), Alternatively, a sliding member (second sliding member; not shown) for sliding the protective cover 2 against the contact object may be provided. This is because the protective cover 2 can be easily inserted into the groove G even in this case. In short, it is sufficient that there is at least one of the first ridge P, the first slide <3, the second ridge, and the second slide.

[Embodiment 4]

Embodiment 4 will be described. Note that members having the same functions as those used in Embodiments 1 to 3 are denoted by the same reference numerals, and description thereof is omitted. In this embodiment, the protective cover 2 will not be dropped from the groove G and will be described in detail.

[0065] When the protective cover 2 is attached to the bezel 3 by being inserted into the groove G, the protective cover 2 may fall out of the groove G, and as a result, the protective cover 2 may fall out of the bezel 3. possible. Therefore, it is preferable that the bottom of at least one groove G faces the direction in which the protective cover 2 moves by gravity (the direction of gravity). That is, the bottom of at least one groove G should be kept horizontal. This is because, at the bottom of the groove G, the protective cover 2 that is about to fall off the bezel 3 by gravity is fastened.

[0066] However, as shown in FIG. 12, the hook provided in the facing portion 3a of the bezel 3 is also protruded. A part of the fat frame 39 may be used to prevent the protective cover 2 from falling off (this part is referred to as a drop-off preventing piece R).

[0067] When the wearing of the protective cover 2 to the bezel 3 is started, the fall-off prevention piece (drop-off prevention portion) R avoids and moves (in the direction of the arrow X) so as not to obstruct the attachment. On the other hand, when the protective cover 2 is attached to the bezel 3, the fall-off preventing piece R is locked and moved (in the arrow Y direction) so as to suppress the movement of the protective cover 2. Also, when removing the protective cover 2 from the bezel 3 (in case of dismounting), the fall-off prevention piece R can be moved in an avoidance manner.

That is, only after the protective cover 2 is attached to the bezel 3, the drop-off preventing piece R is engaged with the protective cover 2 and stops moving the protective cover 2. For this reason, the fall-off prevention piece R does not cause any obstacle when the protective cover 2 is attached / detached, but effectively stops the movement of the protective cover 2 after the protective cover 2 is attached.

[0069] Note that the avoidance movement and the locking movement described above are movements in the in-plane direction on the surface 3aa of the facing portion 3a. However, the movement of the drop-off prevention piece R is not limited to this. For example, avoidance movement and locking movement in a direction perpendicular to the in-plane direction to be applied may be used.

[0070] If this is the case, for example, the drop-off prevention piece R may be positioned on the facing portion 3a constituting the short side where the attachment portion 5 in FIG. 6 is not provided. This is because, when the protective cover 2 is attached to or detached from the bezel 3, the fall-off prevention piece R moves while avoiding being embedded in the bezel 3 so as not to obstruct the attachment. This is because, after the protective cover 2 is mounted, it moves so as to protrude from the surface 3aa of the facing portion 3a so as to suppress the movement of the protective cover 2.

[0071] In short, the fall-off prevention piece R is separated from the protective cover 2 when the protective cover 2 is attached to the bezel 3 and when the protective cover 2 of the bezel is released. After attaching the protective cover 2 to the bezel 3, it is sufficient that the protective cover 2 is in contact with the protective cover 2.

[0072] While the hole 3 is provided in the facing portion 3a of the bezel 3, the protective cover 2 is provided with a protrusion that fits into the hole, and the protrusion and the hole fit together to protect the bezel 3 from falling off. The cover 2 may be allowed to stay (in such a case, the hole can be said to be a drop-off prevention part R). Further, the shape and material of the drop-off prevention piece R are not particularly limited. For example, metal or oil Another member such as a drop-off prevention piece R may be used.

[0073] [Other Embodiments]

The present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the spirit of the present invention.

[0074] For example, the material of the attachment portion 5 is not particularly limited, and various materials may be used. Further, the mounting portion 5 described above is formed by making a cut in the facing portion 3a of the bezel 3, and bending the cut portion so as to protrude toward the surface 3aa. However, the present invention is not limited to this.

[0075] For example, the attachment portion 5 may be formed by providing another member on the surface 3aa of the facing portion 3a.

Alternatively, an opening may be provided in the facing portion 3a of the bezel 3, and a resin frame 39 that protrudes from the opening may be protruded, and the protruding portion may be used as the attachment portion 5 (this attachment portion 5 is also provided on the surface 3aa of the facing part 3a!

[0076] In addition, the mounting portion 5 is a force that has listed the one having the groove G, but is not limited thereto. For example, the mounting portion 5 may be a screw or an insertion / removal pin that can be used to stop or remove the protective cover 2 after the protective cover 2 is arranged at a desired position on the bezel 3. In short, the member required for attaching the protective cover 2 to the bezel 3 can be said to be the attachment portion 5. However, it is desirable that the mounting part 5 allows the protective cover 2 to be detached from the bezel 3, such as a groove G screw.

[0077] Finally, it is obvious that embodiments obtained by appropriately combining the techniques disclosed above are also included in the technical scope of the present invention! /.
