Description

  The present invention relates to a hinge type solenoid and a winning device for a gaming machine including the hinge type solenoid.

  A solenoid is mounted on a gaming machine such as a pachinko machine as an electro-mechanical converter, and a plunger type solenoid and a hinge type solenoid are generally known. Among these, the plunger type solenoid reciprocates so that when the coil wound around the fixed core is excited or demagnetized, the plunger (movable core) arranged in the fixed core moves into and out of the fixed core. Move linearly. On the other hand, when the coil wound around the fixed core is excited or demagnetized, the hinge type solenoid causes the flapper (movable plate) held by the housing (yoke) to swing relative to the fixed core. Since it swings so as to approach and separate, it is also called a flapper type solenoid or a magnet type solenoid.

  The plunger of the plunger-type solenoid always starts with a monotonous linear motion, but the flapper of the hinge-type solenoid can be given a decorative usage pattern or a custom-made design by applying a change in shape or movement. By the way, as shown in Patent Document 1, the flapper of the hinge type solenoid is supported at two points on the housing so that the left and right protrusions form a swing fulcrum, or as shown in Patent Document 2, the housing is bent. Generally, the left and right engaging protrusions are supported at two points so as to be able to swing, and the swinging motion is repeated while being in frictional contact between the housing and the metal. In Patent Documents 1 and 2, when trying to realize a support structure in which the flapper is supported evenly on the left and right with respect to the housing and the swinging motion can be smoothly performed over a long period of time, the flapper and the housing are partially bent or crimped. It is necessary to adopt a special support structure that requires precise metal processing. Such a support structure requires cumbersome processing work and mounting work, and may require special jigs and tools, which may increase the manufacturing cost required for metal processing and assembly of the flapper and housing. .

  Further, since the flapper and the housing are always in metal contact in the swing support portion of Patent Documents 1 and 2, noise and wear are inevitable in the metal contact (swing support) portion. Therefore, in the case of hinge-type solenoids, there has been a contrivance to prevent the deterioration of the environment due to noise and the reduction of life due to wear by preventing or suppressing the occurrence of noise and wear due to metal contact between the flapper and the housing. Various things have been done. For example, in Patent Documents 3 and 4, the flapper is supported at two points on the housing in a swingable manner with a cushioning member such as rubber or resin interposed between the left and right support portions where the flapper contacts the housing. ing. On the other hand, in Patent Document 5, a flapper whose entire surface is coated with an elastic thin film layer such as rubber or resin is supported by a housing in a swingable manner.

  However, in the former (Patent Documents 3 and 4), since the buffer members are interposed in the gaps between the left and right contact portions of the flapper and the housing, the left and right buffer members are changed for each individual and according to the change over time. If the thickness or the like is not adjusted, the flapper may not be able to swing smoothly. In the latter (Patent Document 5), since the entire surface of the flapper is coated with an elastic thin film layer, if the elastic thin film layer is thin, the metal background may be immediately exposed at the contact portion with the housing. On the other hand, if the elastic thin film layer is thick, the flapper suction performance by the iron core may be lowered, so that it is difficult to adjust the thickness of the elastic thin film layer.

Japanese Patent No. 2957343 Japanese Patent No. 3585543 Japanese Patent No. 311297 Japanese Patent Laid-Open No. 11-195525 JP 2000-1114035 A

  The object of the present invention is to eliminate a troublesome metal processing operation and mounting operation such as bending or caulking a movable plate or a housing, suppressing the manufacturing cost, and allowing the movable plate to smoothly perform a swinging motion over a long period of time. It is an object to provide a hinge-type solenoid having a hinge and a winning device for a gaming machine including the hinge-type solenoid. Alternatively, a hinge-type solenoid having a holding structure that reduces the occurrence of noise and wear by avoiding metal contact between the movable plate and the housing, and the movable plate can smoothly swing over a long period of time, and its hinge type Provide a gaming machine winning device equipped with a solenoid.

Means for Solving the Problems and Effects of the Invention

In order to solve the above problems, the hinge type solenoid of the present invention is
A metal housing having an iron core on which a coil is wound and constituting a yoke, and a metal housing that is held in the housing and swings toward or away from the iron core when the coil is excited or demagnetized. In a hinge-type solenoid provided with a movable plate,
The movable plate has a hinge portion for supporting the intermediate portion as a pivotable fulcrum portion so that one end portion side of the movable plate faces the iron core, and is attached and fixed to the housing. A movable plate holding member made of molecular material;
A movable plate that is disposed on the other end side of the movable plate (for example, between the movable plate holding member and the other end side of the movable plate) and is released from being attracted by the iron core as the coil is demagnetized. A return means for rotating and returning,
In the excitation state of the coil, one end side of the movable plate is attracted to the iron core and the fulcrum portion is supported by the hinge portion, and rotates in one direction (the direction in which the one end portion side of the movable plate approaches the iron core). While
In the demagnetized state of the coil, the movable plate is released from being attracted to the iron core on one end side, and the fulcrum portion is supported on the hinge portion by the return means (on one side of the movable plate). The rotation is returned in the direction in which the side is separated from the iron core).

  In this hinge type solenoid, the hinge part of the movable plate holding member made of polymer material fixed to the metal housing holds the fulcrum part of the metal movable plate in a swingable manner, so that the movable plate and the housing are bent. It is possible to eliminate troublesome metal processing work and attachment work such as crimping and caulking. In addition, the movable plate holding member can be integrally formed with the movable plate and the housing by injection molding, etc., so that the movable plate can be smoothly oscillated over a long period of time while suppressing manufacturing costs. The structure can be realized. In addition, since the hinge portion of the movable plate holding member can hold the fulcrum portion of the movable plate over the entire width, the movable plate is less likely to be twisted and bent, and the swing motion can be supported in a stable posture. In addition, the movable plate and the housing are less likely to be in direct metal contact, and noise and wear are reduced at the contact point between the two, realizing a holding structure that allows the movable plate to smoothly swing over a long period of time. It becomes easy to do. Such a movable plate holding member may be divided into a plurality of partition portions and fixedly attached to the housing, and a hinge portion may be formed by the plurality of partition portions.

  The “hinge portion” can be formed by a punched insertion hole (through hole) or a notch-shaped recess (opening). In addition, the “polymer material” includes a synthetic resin (plastic) that exhibits plasticity near normal temperature and an elastomer that exhibits rubber-like elasticity near normal temperature. Further, the “returning means” has a function of always urging one end of the movable plate in the longitudinal direction in a direction away from the iron core, and in addition to a spring member such as a coil spring, a torsion coil spring, a leaf spring, a permanent magnet It may be used. By the way, in order to attach and fix the movable plate holding member made of a polymer material to the metal housing, the movable plate holding member is engaged and fixed to the housing by using the elasticity of the movable plate holding member, or the movable plate holding is performed by insert molding The member may be integrated with the housing, but the movable plate holding member may be attached and fixed to the housing by a fastening means such as a screw or an adhesive means such as affixing.

  The movable plate holding member is capable of detachably holding the movable plate by supporting the movable plate (the fulcrum portion thereof) with a hinge portion in a state before being fixed to the housing. In the fixed state, the fulcrum portion of the movable plate is supported by the hinge portion so as to be swingable in a state in which it cannot be attached and detached.

  By assembling the movable plate holding member to the housing, the movable plate holding member or the movable plate (fulcrum portion) can be attached to the housing, so that the degree of freedom in design for these members is improved.

  The hinge part of the said movable plate holding member is formed in the flat insertion hole for inserting a movable plate from the other end part side or one end part side, and supporting a fulcrum part. When the hinge portion of the movable plate holding member is formed with an insertion hole (through hole), the fulcrum portion of the movable plate is held by the inner wall surface of the insertion hole over the entire width, so the movable plate (fulcrum portion) is supported by the hinge portion. Strength is improved.

  Such an insertion hole can be formed, for example, as a rectangular hole that opens slightly larger than the cross-sectional shape of the inserted movable plate. The movable plate can be formed by bending a thin metal plate at a plurality of locations in the longitudinal direction, for example.

  The movable plate holding member slides with respect to the housing in the coil adsorption direction (specifically, a direction intersecting (for example, orthogonal to) the insertion direction of the movable plate), and between the movable plate holding member and the housing. Is provided with a plurality of engaging portions. The plurality of engaging portions facilitate the assembly of the movable plate holding member and the housing, and consequently the assembly of the hinge type solenoid as a whole. In addition, since the sliding direction of the movable plate holding member is different from the insertion direction of the movable plate, when the movable plate holding member is attached to the housing, the movable plate holding position (fulcrum) of the movable plate holding member is shifted. Hateful. Even if there is a difference in thermal expansion between the movable plate holding member and the housing made of different materials, the fixed state of both can be maintained through the plurality of engaging portions, so that the movable plate holding member and the housing are assembled. The accuracy, and thus the assembly accuracy of the hinge type solenoid as a whole, is improved.

  Such an engaging portion is, for example, an engaging claw that is integrally formed with the movable plate holding member by injection molding or the like and can be elastically deformed, or is integrally formed with the movable plate holding member by injection molding or the like, and the engaging convex portion of the housing. Can be formed as an engaging groove into which can be fitted.

  An insertion restricting portion for restricting the amount of insertion of the movable plate into the insertion hole is formed at the fulcrum portion of the movable plate. By the insertion restricting portion, the positioning accuracy in the longitudinal direction (insertion direction) of the movable plate with respect to the movable plate holding member is improved.

  Such an insertion restricting portion can be formed on the movable plate as a wall surface that abuts the surface of the movable plate holding member at the peripheral portion of the insertion hole. When the insertion hole is a rectangular hole, positioning accuracy in the width direction and thickness direction of the movable plate with respect to the movable plate holding member is improved by the inner wall surface of the rectangular hole.

  The movable plate holding member is formed with a rotation restricting portion for contacting the movable plate and restricting the amount of rotation before the movable plate and the iron core come into contact with each other when the coil is excited. The rotation restricting portion prevents the movable plate and the iron core from coming into direct metal contact, thereby avoiding noise and wear caused by the contact between the two.

  Such a rotation restricting portion can be integrally formed on the movable plate holding member by, for example, injection molding.

  The return means is a permanent magnet that attracts the other end of the movable plate and maintains the return state in the demagnetized state of the coil, and the movable plate holding member is formed with a housing portion that houses the permanent magnet. Since the housing portion does not protrude from the movable plate holding member and the permanent magnet as the return means can be housed inside, the movable plate holding member and thus the hinge type solenoid can be reduced in size.

  Therefore, when such a hinge-type solenoid is used in a game machine winning device, it is possible to easily prevent the winning ball and the return means (permanent magnet) from interfering with each other, so that the permanent magnet (and the housing portion) can receive the winning ball path. It does not inhibit. Note that the attractive force of the permanent magnet is smaller than the attractive force of the iron core in the excited state of the coil.

  The fulcrum portion of the movable plate (flapper) can be provided with a notch groove into which the protruding wall portion of the housing (yoke) can be fitted. Thereby, the positioning accuracy in the width direction between the movable plate and the housing is improved.

Therefore, in order to solve the above problems, the hinge type solenoid of the present invention is
A metal housing having an iron core on which a coil is wound and constituting a yoke, and a metal housing that is held in the housing and swings toward or away from the iron core when the coil is excited or demagnetized. In a hinge-type solenoid provided with a movable plate,
A hinge portion for swingably supporting the movable plate so that one end portion side of the movable plate is disposed opposite to the iron core, and supported by the hinge portion with an intermediate portion of the movable plate as a fulcrum portion; A movable plate holding member made of a polymer material that is attached and fixed to the housing,
A movable plate that is disposed on the other end side of the movable plate (for example, between the movable plate holding member and the other end side of the movable plate) and is released from being attracted by the iron core as the coil is demagnetized. A return means for rotating and returning,
In the excitation state of the coil, one end side of the movable plate is attracted to the iron core and the fulcrum portion is supported by the hinge portion, and rotates in one direction (the direction in which the one end portion side of the movable plate approaches the iron core). While
In the demagnetized state of the coil, the movable plate is released from being attracted to the iron core on one end side, and the fulcrum portion is supported on the hinge portion by the return means (on one side of the movable plate). The rotation is returned in the direction in which the side is separated from the iron core).

The above-described hinge type solenoid can also be expressed as follows.
A metal housing having an iron core on which a coil is wound and constituting a yoke, and a metal housing that is held in the housing and swings toward or away from the iron core when the coil is excited or demagnetized. In a hinge-type solenoid provided with a movable plate,
The movable plate having a flat insertion hole through which the movable plate is inserted from the other end side or the one end side so that one end portion side of the movable plate is disposed to face the iron core. A movable plate holding member made of a polymer material attached and fixed to the housing in a state where the insertion hole is supported as a fulcrum that can swing the intermediate portion of
A movable plate that is disposed on the other end side of the movable plate (for example, between the movable plate holding member and the other end side of the movable plate) and is released from being attracted by the iron core as the coil is demagnetized. A return means for rotating and returning,
In the excitation state of the coil, one end side of the movable plate is attracted to the iron core and the fulcrum portion is supported by the hinge portion, and rotates in one direction (the direction in which the one end portion side of the movable plate approaches the iron core). While
In the demagnetized state of the coil, the movable plate is released from being attracted to the iron core on one end side, and the fulcrum portion is supported on the hinge portion by the return means (on one side of the movable plate). (The direction in which the side is separated from the iron core) is returned to the rotation.

Further, the assembly method of the hinge type solenoid can also be expressed as follows.
A metal housing having an iron core on which a coil is wound and constituting a yoke, and a metal housing that is held in the housing and swings toward or away from the iron core when the coil is excited or demagnetized. In a method for assembling a hinge-type solenoid comprising a movable plate,
With respect to the flat insertion hole formed in the movable plate holding member made of a polymer material, the movable plate is moved to the other end side or one end portion so that the one end side of the movable plate is disposed to face the iron core. An insertion process to be inserted from the side,
An attaching step of attaching and fixing the movable plate holding member to the housing in a state where the insertion hole holds the intermediate portion of the inserted movable plate as a pivotable fulcrum portion.

  In such a hinge type solenoid or a method of assembling the hinge type solenoid, the movable plate holding member is attached and fixed to the housing in a state where the insertion hole of the movable plate holding member holds the middle portion of the movable plate in a swingable manner. Therefore, troublesome metal processing work can be eliminated, and attachment work becomes easy. In addition, since the insertion hole of the movable plate holding member can hold the fulcrum portion of the movable plate over the entire width, the movable plate is less likely to be twisted and bent, and the swing motion can be supported in a stable posture.

Therefore, in order to solve the above-mentioned problem, the prize winning device for gaming machine of the present invention is

The movable plate of the hinge-type solenoid is characterized in that the rotating blade piece is rotationally displaced about its rotational axis via the transmission member.

  As a result, the movable function of the hinge-type solenoid enhances the decorative function, while the deterioration of the game environment due to noise from the hinge-type solenoid and the decrease in the life of the hinge-type solenoid due to wear can be avoided. A winning device can be easily realized. In addition to the double wing type provided with a pair of left and right rotating wing pieces, the rotating wing piece is provided only on one of the left and right sides, and the other is also applied to the single wing type provided with a fixed wall portion. it can. In the case of the double blade type, the pair of rotating blade pieces can be rotationally displaced individually or simultaneously around the rotational axis.

  In such a prize-winning device for gaming machines, the following means may be employed in order to reduce the size of the entire device and install it in a narrow arrangement space in the gaming machine.

  For example, the transmission member is a lifting member that converts the swinging motion of the movable plate in the hinge-type solenoid into its own vertical lifting motion, and converts the lifting motion into the rotational motion of the rotating blade piece and transmits it. There may be. The movable board, the lifting member (transmission member) and the rotary wing piece are made different in type and direction of movement, and combined with the lifting member to reduce the size of the winning device, so that a narrow arrangement space in the gaming machine Also, a winning device can be installed.

Example 1
Hereinafter, embodiments of the present invention will be described with reference to examples shown in the drawings. 1 is an overall perspective view showing an example of a hinge-type solenoid (hereinafter also simply referred to as a solenoid) according to the present invention, FIG. 2 is an exploded perspective view thereof, and FIG. 3 is an overall perspective view seen from a direction different from FIG. FIG. 4 is an exploded perspective view thereof. As shown in FIGS. 1 to 4 (for example, FIGS. 1 and 3), the solenoid 10 has an iron core 2 around which a coil 1 is wound, and is made of a metal (for example, a steel plate) that constitutes a yoke having an L-shaped cross section. A housing 3, a flapper holder 5 (movable plate holding member) made of a polymer material (for example, synthetic resin) fixed to the housing 3, and a metal (for example, swinging held by the housing 3 via the flapper holder 5 A steel plate) flapper 4 (movable plate), and a permanent magnet 6 (return means) that acts to keep the flapper 4 away from the iron core 2 at all times. The flapper 4 swings so as to approach or separate from the iron core 2 when the coil 1 is excited (energized) or demagnetized (de-energized).

  As specifically shown in FIG. 2, the flapper 4 is formed by bending a thin metal plate at a plurality of locations in the longitudinal direction, of which the middle portion in the longitudinal direction is formed as a flat middle bent portion 40. The flapper holder 5 is held swingably. That is, a notch groove 43 is formed on both sides of the center portion of the intermediate bent portion 40 of the flapper 4 in the longitudinal direction, and a portion excluding the notch grooves 43 on both sides at the center portion in the longitudinal direction is a fulcrum portion as a swing center 40c (details will be described later). Further, one end in the longitudinal direction of the notch groove 43 is divided into a wide portion 40a and the other end is formed into a narrow portion 40b. Furthermore, the one end portion (wide portion 40a) in the longitudinal direction of the intermediate bent portion 40 has a predetermined step, extends in parallel with the same width as the wide portion 40a, and is opposed to the iron core 2 and opposed to the iron core 2. A portion 41 is formed (the width is narrow at the tip of the core facing portion 41). On the other hand, on the other end portion (narrow portion 40b) side, a magnet facing portion 42 that is bent in an L shape (orthogonal shape) with the same width as the narrow portion 40b and is disposed to face the permanent magnet 6 is formed. .

  A flat rectangular hole 50 (insertion hole) that is wider than the narrow portion 40 b and narrower than the wide portion 40 a and opens larger than the thickness of the flapper 4 is formed through the lower portion of the flapper holder 5. The intermediate bent portion 40 (fulcrum portion 40 c) of the flapper 4 inserted through the rectangular hole 50 is swingably held by the flapper holder 5. Specifically, when the flapper 4 is inserted into the rectangular hole 50 from the magnet facing portion 42 side, the wall surface 43a on the wide portion 40a side forming the cutout groove 43 in the intermediate bent portion 40 is the flapper in the peripheral portion of the rectangular hole 50. The side surface of the flapper 4 is restricted by the vertical surface of the rectangular hole 50 and swings about the fulcrum 40c.

  Thus, the rectangular hole 50 (the inner wall surface 50a thereof) functions as a hinge portion that holds the fulcrum 40c of the swing over the entire width in the intermediate bent portion 40 of the flapper 4 (FIGS. 5C and 6C). B)). The flapper 4 (the intermediate bent portion 40) is positioned with respect to the flapper holder 5 in the width direction and the thickness direction by the inner wall surface 50a of the rectangular hole 50. Further, the wall surface 43 a on the wide portion 40 a side of the notch groove 43 formed in the intermediate bent portion 40 abuts on the flapper holder 5 when the flapper 4 is attached to the flapper holder 5, and the flapper 4 with respect to the rectangular hole 50. It functions as an insertion restricting portion for restricting the insertion amount in the longitudinal direction (see FIG. 5D).

  Further below the rectangular hole 50 of the flapper holder 5, a receiving portion 53 is provided for receiving the wide portion 40a of the intermediate bent portion 40 of the flapper 4 from below when the coil 1 is demagnetized (non-energized). The receiving portion 53 is formed integrally with the flapper holder 5 (see FIG. 5C).

  The permanent magnet 6 is housed in a housing portion 54 that is formed in a depression at the center of the flapper holder 5, and has a function of attracting the magnet facing portion 42 of the flapper 4 to maintain the return state when the coil 1 is demagnetized (non-energized). Have Therefore, the attractive force of the permanent magnet 6 is set to be smaller than the attractive force of the iron core 2 when the coil 1 is excited (energized). Therefore, when the flapper 4 swings around the fulcrum portion 40c, when the iron core facing portion 41 is rotated so as to approach the iron core 2, the magnet facing portion 42 is separated from the permanent magnet 6 (FIG. 6B). When the iron core facing portion 41 is turned away from the iron core 2, the magnet facing portion 42 approaches the permanent magnet 6 (see FIG. 5C). However, since the permanent magnet 6 is accommodated in the accommodating part 54, the magnet facing part 42 does not contact the permanent magnet 6 directly, and generation | occurrence | production of noise is prevented.

  FIG. 7 is a perspective view in which the form during assembly is viewed from two different directions. Specifically, the process of assembling the housing 3 to which the coil 1 and the iron core 2 are attached and the flapper holder 5 to which the flapper 4 and the permanent magnet 6 are detachably attached is shown in FIGS. 7 (A) and 7 (B). Yes. The flapper holder 5 and the housing 3 slide relative to each other in the vertical direction (that is, the direction orthogonal to the insertion direction of the flapper 4), and are integrated by a plurality of engaging portions provided therebetween.

  For example, a pair of left and right outward engaging claws 51, 51 (engagement portion) integrally formed with the flapper holder 5 are formed in a pair of left and right engagement recesses 31, 31 (engagement portion) formed in the housing 3. On the other hand, they engage with each other while being elastically deformed. In addition, a pair of left and right engaging projections 32 and 32 (engagement portion) formed in the housing 3 are fitted into a pair of left and right engagement grooves 52 and 52 (engagement portion) formed integrally with the flapper holder 5. To do. As a result, the flapper holder 5 is assembled to the housing 3. That is, the flapper 4 can be attached to the housing 3 in a swingable manner simply by assembling the flapper holder 5 temporarily holding the flapper 4 to the housing 3.

  That is, as shown in FIG. 7, in a state before the flapper holder 5 is attached and fixed to the housing 3, the rectangular hole 50 of the flapper holder 5 supports the flapper 4 (the fulcrum portion 40 c), and the flapper 4 is detachable. Can be retained. On the other hand, in the state after the flapper holder 5 is attached and fixed to the housing 3 as shown in FIG. doing.

  As shown in FIGS. 4 and 7, a pair of left and right projecting wall portions 33, 33 are formed between the engaging convex portions 32, 32 of the housing 3 by a notch k narrower than the rectangular hole 50. In the assembly process of the flapper holder 5 and the housing 3, the protruding wall portions 33 and 33 are fitted into the notch grooves 43 and 43 formed in the intermediate bent portion 40 of the flapper 4. The flapper 4 (the fulcrum portion 40 c) is positioned with respect to the housing 3 by the protruding wall portions 33 and 33 and the cutout grooves 43 and 43. At this time, the sheet metal of the housing 3 and the resin of the flapper holder 5 partially overlap, and at least the notch k is formed larger than the rectangular hole 50 in the height direction. That is, the flapper 4 is positioned with a clearance from the end face of the sheet metal of the housing 3, and is held swingably in the rectangular hole 50 of the flapper holder 5 without contacting the housing 3.

  Next, the operation of the solenoid 10 will be described. As shown in FIG. 6, when the coil 1 is excited (energized), the iron core facing portion 41 of the flapper 4 is attracted to the iron core 2 and held by the inner wall surface 50 a (lower wall surface) of the rectangular hole 50 of the flapper holder 5. While being done, it pivots upward about the fulcrum 40c. Thereby, the iron core facing portion 41 is attracted to the iron core 2, and the magnet facing portion 42 is separated from the permanent magnet 6 (see FIG. 6B).

  As shown in FIG. 5, when the coil 1 is demagnetized (non-energized), the suction of the iron core facing portion 41 to the iron core 2 is released, so that the flapper 4 is caused by its own gravity and the attractive force of the permanent magnet 6. While being held in the rectangular hole 50 of the flapper holder 5, it is turned downward and returned to the center of the intermediate bent portion 40. As a result, the iron core facing portion 41 is separated from the iron core 2, and the magnet facing portion 42 is close to the permanent magnet 6. When the intermediate bent portion 40 of the flapper 4 comes into contact with the receiving portion 53, the rotation of the flapper 4 is stopped (see FIG. 5C).

  In this way, the rectangular hole 50 of the flapper holder 5 made of synthetic resin fixed to the metal housing 3 holds the fulcrum 40c of the metal flapper 4 in a swingable manner, so that the flapper 4 and the housing 3 are connected to each other. It becomes difficult for the metal to come into direct contact with each other, and the occurrence of noise and wear at the contact portion between the two is reduced. Further, the flapper holder 5 includes a rectangular hole 50 that is an engagement portion with the flapper 4, a receiving portion 53, an engagement claw 51 that is an engagement portion with the housing 3, an engagement groove 52, and a permanent magnet. Since the six accommodating portions 54 can be integrally formed by injection molding or the like, it is possible to realize a holding structure in which the flapper 4 can smoothly perform a swinging motion over a long period while suppressing the manufacturing cost. In addition, since the hinge portion of the flapper holder 5 is formed by the rectangular hole 50 and the fulcrum portion 40c of the flapper 4 is held so as to be swingable over the entire width, the support strength of the intermediate bent portion 40 in the rectangular hole 50 is improved. The flapper 4 is less likely to be twisted or bent, and can support a swinging motion in a stable posture.

  Further, a plurality of engagement portions (engagement claw 51 and engagement recess 31, engagement groove 52 and engagement protrusion 32) are provided between the flapper holder 5 and the housing 3. The plurality of engaging portions facilitate the assembly of the flapper holder 5 and the housing 3, and consequently the assembly of the solenoid 10 as a whole. Further, even if a difference in thermal expansion occurs between the flapper holder 5 made of synthetic resin and the metal housing 3, the fixed state of both can be maintained through the plurality of engaging portions. As a result, the assembly accuracy of the solenoid 10 as a whole is improved.

FIG. 8 is a sectional view showing a first modification of the hinge type solenoid. In the solenoid 10 shown in FIG. 8, a coil spring 6 ′ (return means) is disposed between the flapper holder 5 (movable plate holding member) and the rear end of the fulcrum 40 of the flapper 4 (movable plate). The coil spring 6 ′ acts so as to always keep the iron core facing portion 41 of the flapper 4 away from the iron core 2, and the spring force is set to be smaller than the attractive force of the iron core 2 when the coil 1 is excited (energized). .

(Modification 1-2)
FIG. 9 is an exploded perspective view showing a second modification of the hinge type solenoid. The flapper holder 5 ′ (movable plate holding member) of the solenoid 10 shown in FIG. 9 is wider than the narrow portion 40b of the flapper 4 (movable plate) and narrower than the wide portion 40a. A recessed portion 50 ′ in which a larger flat hole is opened in a notch shape is formed, and a fulcrum portion 40 c of the flapper 4 inserted through the recessed portion 50 ′ is swingably held by the flapper holder 5.

  Specifically, when the flapper 4 is inserted from the magnet facing part 42 side into the recessed part 50 ′, the wall surface 43a on the wide part 40a side forming the notch groove 43 in the intermediate bent part 40 is the flapper on the peripheral part of the recessed part 50 ′. The holder 5 comes into contact with the surface and stops, and the fulcrum 40c is positioned in the recess 50 ′. Thus, the recess 50 '(the inner wall surface 50a') functions as a hinge portion that holds the fulcrum portion 40c of the flapper 4 so as to be swingable over the entire width.

(Modification 1-3)
FIG. 18 is an explanatory view showing a third modification of the hinge-type solenoid, showing a modification of the flapper (movable plate). In the intermediate bent portion 40 ′ of the flapper 4 ′ shown in FIG. 18, the width of the fulcrum portion 40c ′ is formed to be equal to the width of the narrow portion 40b ′, and the narrow portion 40b ′ is the longitudinal length of the intermediate bent portion 40 ′. It extends from the notch groove 43 ′ formed on both sides of the central portion in the direction to one end portion side in the longitudinal direction (iron core 2 side in FIG. 2). Furthermore, the front end portion of the narrow portion 40b ′ has a predetermined step and extends in parallel with the same width as the narrow portion 40b ′ to form an iron core facing portion 41. On the other hand, the other end side (the permanent magnet 6 side in FIG. 2) is bent in an L shape (orthogonal shape) with the same width as the wide portion 40a ′, and a magnet facing portion 42 is formed.

  Accordingly, the flapper 4 ′ is inserted into the rectangular hole 50 (see FIG. 2) from the iron core facing portion 41 side, and the wall surface 43a ′ on the wide portion 40a ′ side forming the cutout groove 43 in the intermediate bent portion 40 ′ is formed into the rectangular hole. 50 (refer to FIG. 2) abuts against the surface of the flapper holder 5 at the peripheral edge and stops, and swings around the fulcrum 40c ′.

  At the upper end of the enclosure wall 143, there are an opening stop surface 143a (first restricting portion) for restricting the opening position of the rotary blade piece 120, and a closing stop surface 143b (second restricting portion) for restricting the closing position. Are formed separately. Specifically, the release stop surface 143a abuts on the outer surface 120a of the rotating blade piece 120 in the open state to regulate the open position (see FIG. 17B). On the other hand, the closing stop surface 143b regulates the closed position by the projection 123 formed to project forward from the rotary blade piece 120 in the closed state (see FIG. 15B).

  The guide rod 112, the front wall portion 113F, and the rear wall portion 113R are each integrally formed of the base plate 110 and the synthetic resin. Further, the bearing boss portion 141, the winning prize basket 142, and the surrounding wall 143 are integrally formed with the front decorative member 140 and synthetic resin, respectively.

  The elevating member 130 is provided at the front middle lower position of the pair of rotating blade pieces 120 behind the front decoration member 140 and moves up and down by the driving force when the flapper 4 (movable plate) of the solenoid 10 rotates. Then, a transmission member is configured to convert it into a rotational motion of each rotary blade 120 and transmit it. Specifically, the iron core facing portion 41 of the flapper 4 further extends forward, and is formed in an extending portion 44 that is bent at a plurality of locations in the longitudinal direction (the end portion of the extending portion 44 has a narrow width). ). A flat engaging hole 134 (through-hole) that is wider than the extending portion 44 of the flapper 4 and opens larger than the plate thickness of the flapper 4 is formed in the lower part of the vertically rising and lowering body 131 in the lifting member 130. ) Is formed in a penetrating manner, and the distal end portion (narrow portion) of the extended portion 44 is inserted and held in the engagement hole 134.

Side walls 133 in the front-rear direction are formed at both left and right ends of the elevating body 131, and the side walls 133 extend along the inner surfaces of a pair of left and right guide wall portions 143c formed integrally with the enclosure wall 143 of the front decorative member 140. And is slidable in the vertical direction along the front wall of the front decorative member 140. That is, the extended portion 44 of the flapper 4 is an action portion, and the engaging hole 134 of the elevating member 130 (elevating body 131) functions as an actuated portion, whereby the swinging motion of the flapper 4 is caused by the elevating member 130 (elevating / lowering). It is converted into a vertical motion of the main body 131) and further converted into a rotational motion of the rotary blade 120.

  Since the separation distance L1 (distance between the support points) of the engagement pin 122 is smaller than the separation distance L2 (distance between the rotation axes) of the rotation shaft 111 (L1 <L2), the winning device 100 is compact. The side wall 133 (elevating member 130) can be moved up and down and the rotating blade piece 120 can be rotated smoothly. By providing the front decorative member 140 with a guide wall portion 143c for guiding the elevating member 130 and restricting portions 143a and 143b for restricting the rotation range (opening / closing range) of the rotating blade piece 120, the winning device 100 is further increased. Small and simple configuration.

  The light emitting substrate 150 is formed in a pseudo semicircular shape because it has a central opening 150a for allowing a winning ball to pass through in the center, and light emitting means (not shown) such as an LED for irradiating the base plate 110 with light.

Sent and detected as a winning ball.

  Further, since the enclosure wall 143 of the front decorative member 140, the front wall portion 113F and the rear wall portion 113R of the base plate 110, and the case wall portion 160b of the rear case 160 constitute a series of walls from the front side to the rear side. These have a function as a protective wall that protects the rotating blade 120 from a forced opening operation, which is an illegal act. In particular, a guide wall portion 143c that guides the side wall portion 133 of the elevating member 130 is disposed inside the enclosure wall 143, and double protection is performed (see FIGS. 15B and 17B). ).

  Next, the operation of the winning device 100 (rotating blade piece 120) will be described with reference to FIGS. 14 is a front view and a side view of the rotating blade piece 120 in the closed state, FIG. 15 is a sectional view taken along the line CC and DD, and FIG. 16 is a front view and a side view of the rotating blade piece 120 in the opened state. 17 and 17 are a C′-C ′ sectional view and a D′-D ′ sectional view, respectively.

<Closed state of rotating blade piece 120> (FIGS. 14 and 15)
As already described in the first embodiment (FIG. 5), when the coil 1 of the solenoid 10 is in a demagnetized (non-energized) state, the attraction of the iron core facing portion 41 to the iron core 2 is released. The intermediate bent portion 40 of the flapper 4 is in contact with the receiving portion 53 by being rotated downward about the fulcrum portion 40c while being held in the rectangular hole 50 of the flapper holder 5 (FIGS. 15A and 5). (See (C)). At this time, the iron core facing portion 41 of the flapper 4 is separated from the iron core 2, the magnet facing portion 42 is close to the permanent magnet 6, and the extending portion 44 stops the elevating member 130 at the lowered position. The elevating member 130 (elevating body 131) stops at the lowered position, and the protrusion 123 of the rotating blade piece 120 contacts the closing stop surface 143b of the surrounding wall 143, so that the rotating blade piece 120 is maintained in the closed state. Yes.
