  Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

  As shown in FIG. 1 and FIG. 5, the mirror opening device includes a substantially cylindrical barrel frame member 31 having an opening on the upper surface, a mirror lid 1 provided so as to cover the opening of the barrel frame member 31, and a barrel frame. A push-up device 40 that is provided inside the member 31 and applies external force from the lower side of the mirror lid 1 and a discharge device 50 that is provided inside the barrel frame member 31 and discharges a piece of paper upward from the opened opening. Prepare.

  As shown in FIG. 1, the barrel frame member 31 has an opening that opens the upper surface, extends in the height direction, and has a substantially cylindrical side surface portion 31 a having a constriction in the vicinity of the intermediate portion in the height direction, and It is formed in the bottomed cylinder shape provided with the bottom face part 31b. The opening is provided with an edge member 31c for placing the mirror lid 1 at a predetermined position. Moreover, although not shown in figure, various decorations are given to the outer periphery of the side part 31a. For example, a persimmon (rather) is wound around the outer periphery of the barrel frame member 31, and a registered liquor name, company name, pattern, etc. are written on the surface of the side surface portion 31 aq of the barrel frame member 31. It is.

  The mirror lid 1 will be specifically described with reference to FIGS. In addition, the line segment T shown with a dashed-dotted line in FIG.1 and FIG.2 etc. shows the centerline which bisects the mirror opening apparatus horizontally along the boundary between the inner side plate member 1b and the inner side plate member 1c, The outer plate member 1a and the inner plate member 1b side from the center line T are referred to as the “left” side, and the outer plate member 1d and the inner plate member 1c side from the center line T are referred to as the “right” side. The mirror lid 1 has a symmetrical configuration with respect to the center line T as a boundary. Therefore, the description will be omitted as appropriate based on this.

  As shown in FIGS. 1 and 2, the mirror lid 1 is arranged adjacent to each other in the same direction in the plane direction to form a disk shape, thereby forming an outer plate member 1a, an inner plate member 1b, an inner plate member 1c, and an outer plate. Hinge 2a to 2c for connecting the plate member 1d with the outer plate member 1a and the inner plate member 1b adjacent to the outer plate member 1a, and the inner plate member 1c adjacent to the outer plate member 1d and the outer plate member 1d. Hinges 2d to 2f are provided, and the inner plate members 1b and 1c are configured to be rotatable so as to open a so-called double-sided opening on the upper side.

  Also, fixing members 3a and 3b provided on the outer plate member 1a and fixing members 3c and 3d provided on the outer plate member 1d, tension spring members 4a to 4d fixed to the fixing members 3a to 3d, and a tension spring An elastic member 6a that connects the member 4a and the tension spring member 4b via a predetermined path, and an elastic member 6b that connects the tension spring member 4c and the tension spring member 4d via a predetermined path are provided.

  Further, each of the outer plate member 1a, the inner plate member 1b, the inner plate member 1c, and the outer plate member 1d has a plate shape with a predetermined thickness, and has a width L1 in the planar direction as shown in FIG. Further, the outer plate member 1 a, the inner plate member 1 b, the inner plate member 1 c, and the outer plate member 1 d are placed in a state where a disk shape is formed by the edge member 31 c of the barrel frame member 31. Since the outer side plate members 1 a and 1 d are fixed to the edge member 31 c of the barrel frame member 31, the placed state is maintained even when an external force is applied.

  The inner plate member 1b is adjacent to the outer plate member 1a, and as described above, is connected by hinges 2a to 2c on the upper side of the portion adjacent to the outer plate member 1a. Accordingly, the inner plate member 1b is configured to be rotatable about the hinges 2a to 2c as the rotation axis. 2 and 3, the inner plate member 1b has a stopper member 5a on the lower surface side. The stopper member 5a is configured to be able to hook and hold the string-like member. The end surface 7a of the inner plate member 1c on the side adjacent to the inner plate member 1b is formed such that the upper end side of the end surface 7a forms an acute angle with the upper surface of the inner plate member 1b. By doing so, when the inner plate member 1b rotates, it does not contact the adjacent inner plate member 1c.

  The inner plate member 1c is only bilaterally symmetric with respect to the inner plate member 1b and the center line T, and has the same configuration, so the description thereof is omitted. In addition, about the member corresponding to the member which the inner side board member 1b has, a code | symbol is attached | subjected corresponding to the stopper member 5b and the end surface 7b.

In addition, as shown in FIG. 2, the fixing members 3a and 3b are provided at two locations that divide the arc into approximately three equal parts in the portion of the outer plate member 1a that forms the disc-shaped arc. It is preferable that the fixing members 3a and 3b have transparency to such an extent that they cannot be visually recognized even when viewed from a certain distance. The fixing members 3a and 3b are provided on the upper surface or the side end surface of the outer plate member 1a.

  Each of the spring members 4a and 4b has a predetermined biasing force and is connected to each of the fixing members 3a and 3b. Similarly, the tension spring members 4a and 4b preferably have transparency to the extent that they cannot be visually recognized.

  The elastic member 6a applies a force to each of the inner plate members 1b and 1c in such a manner that they are pulled in a plane direction toward the adjacent outer plate members 1a and 1d, and is hinged when an upper external force is applied. It is provided in a state where it is rotated by applying a rotational force with 2a to 2c as a rotation axis.

  Specifically, as shown in FIGS. 2 and 3, the elastic member 6a is connected to the side opposite to the fixing member 3a side of the tension spring member 4a, and the surface of the inner plate member 1b adjacent to the outer plate member 1a. Is passed through the center plate T side end surface 7a of the inner plate member 1b, folded back to the back surface, hooked by the stopper member 5a, and the inner plate member 1b end surface 7a on the center line T side folded back again. It passes through the surface of 1b and is connected to the side opposite to the fixing member 3b side of the tension spring member 4b.

  Here, the action of the elastic member 6 will be described in detail. As shown in FIG. 4A, the elastic member 6a is connected to the tension spring member 4b connected to the fixing member 3b by its own elastic force. The force S2 is generated at the position P2, and the force S1 is generated at the position P1 (the upper end of the end surface on the center line T side) of the end of the inner plate member 1b. In the state of FIG. 4A, the force S1 and the force S2 generated on the elastic member 6a are substantially in the same plane as the plane formed by the outer plate member 1a and the inner plate member 1b. The elastic force is in a balanced state (equilibrium state). Therefore, the outer side plate member 1a and the inner side plate member 1b are stationary in a state as shown in FIGS. 1 to 3 and FIG.

  In the above-described equilibrium state, an external force F0 is applied from the lower side to the upper side in FIG. 4B near the position P1 of the inner plate member 1b, whereby the force S1 at the position P1 is hinged 2c ( It is decomposed in the tangential direction of the circle C2 with the position P3) as the center. Here, when the force disassembled in the tangential direction is a force F1, the force F1 becomes a force for rotating on the inner plate member 1b with the hinge 2c (position P3) as a rotation axis (that is, a rotational force), and upward ( The inner plate member 1b starts to rotate toward the counterclockwise direction in FIG.

  Further, as shown in FIG. 4C, the inner plate member 1b that has started to rotate is further rotated by the force F1 of the tangential decomposition component of the force S1 and rotated vigorously. As shown in FIG. 4D, as a result, the outer plate member 1a and the inner plate member 1b collide so as to face each other. At this time, when the outer plate member 1a and the inner plate member 1b collide, a high impact sound such as a clapping sound is emitted.

  Thus, when a predetermined external force F0 is applied upward to the inner plate member 1b by the elastic member 6a that has retained the elastic force in the plane direction, a predetermined force (here, (Rotating force) is applied from the elastic member 6a, and the inner member 1b rotates about the hinges 2a to 2c as the rotation axis.

  In addition, since the right side of the center line T of the mirror lid 1 has the same configuration as the configuration on the left side of the center line T described above, similarly, by the elastic member 6b that holds the elastic force in the plane direction, When a predetermined external force is applied upward, a predetermined force is applied to the inner plate member 1c from the elastic member 6b, and the inner member 1c rotates about the hinges 2d to 2f as the rotation axis.

  In this way, the opening of the apparatus can be opened vigorously with a simple configuration by the action of the elastic member 6.

  As shown in FIGS. 5 and 6, a push-up device 40 and a discharge device 50 are arranged inside the barrel frame member 31.

  The push-up device 40 includes a push-up device control device 41, a push-up device drive unit 42, and a push-up member 43.

  The push-up device control device 41 receives signals from a control unit 41 a that controls the operation of each component (including the push-up device drive unit 42) of the push-up device 40 and a remote controller (hereinafter referred to as “remote control”) 70 described later. And a transmission / reception unit 41b that transmits a signal for operating each component of the push-up device 40 according to the received signal (see FIG. 8).

  The push-up device drive section 42 receives a drive signal from the push-up device control device 41 and drives it, and a gear box 42b that houses a plurality of gears that transmit the drive force from the drive motor 42a. And a lift member 42c that is rotated by a driving force transmitted through the gear box 42b. In other words, the driving device 42 for the lifting device is driven by the driving motor 42a based on the driving signal transmitted from the controlling device 41 for the lifting device, and is lifted via the gear box 42b by the driving of the driving motor 42a. The member 42c is rotated upward (counterclockwise in FIG. 6).

  As shown in FIG. 6, the push-up member 43 includes a rectangular push-up portion 43a positioned below both of the inner plate members 1b and 1c of the lens cover 1, and a vertical bar portion 43c extending downward from the push-up portion 43a. And a lower end portion 43b that is positioned at the lower end of the vertical bar portion 43c and that is in contact with the lift member 42c. The push-up member 43 is made of a transparent plastic. A plurality of fasteners 44 that restrict movement in the left-right direction are provided around the vertical bar portion 43c. The fastener 44 is, for example, a U-shaped metal member, surrounds the vertical bar portion 43 c with a space, and is fixed to the inner wall surface of the barrel frame member 31. By this fastener 44, the upward movement of the push-up member 43 is guided. That is, the push-up member 43 is restricted from moving in the left-right direction and can move only in the up-down direction.

  As described above, in the push-up device 40, the drive motor 42a is driven based on the drive signal sent from the push-up device control device 41, so that the lift member 42c is moved upward via the gear box 42b (see FIG. 6 in the direction indicated by arrow Z1). By the rotation of the lift member 42c, the lower end portion 43b of the push-up member 43 is lifted upward, and the push-up member 43 rises in the direction indicated by the arrow Z2 in FIG. As a result, the pushed-up portion 43a of the pushed-up member 43 pushed up pushes both the inner side plate members 1b and 1c of the mirror lid 1 located above from below. The push-up force by the push-up member 43 becomes a predetermined external force applied to the above-described inner plate members 1b and 1c of the lens cover 1, and the inner plate members 1b and 1c are indicated by arrows Z3 and Z4 in FIG. The double door is opened and the mirror lid 1 is opened. That is, the opening of the barrel frame member 31 can be opened with mechanical force.

  The above-described push-up device 40 needs to be provided at a position where the push-up portion 43a pushes up both the inner plate member 1b and the inner plate member 1c of the mirror lid 1. That is, the push-up device 40 is disposed above the push-up portion 43a so that at least the inner plate member 1b and the inner plate member 1c are both disposed. In addition, you may make it respond | correspond by changing the magnitude | size of the pushing-up part 43a suitably.

  As shown in FIG. 7, the discharge device 50 is electrically connected to the discharge device control device 51, the discharge device control device 51 through the conductors 51 c, and in response to a signal from the discharge device control device 51. The first discharge part 52 and the second discharge part 53 for discharging the paper piece P upward are provided. Further, the discharge device control device 51, the first discharge portion 52, and the second discharge portion 53 are fixed on the same base 54.

  The discharge device control device 51 receives a signal from the control unit 51a that controls the operation of each component (including the drive motor 524 and the drive motor 534) of the discharge device 50, and a remote controller 70 that will be described later. A transmission / reception unit 51b that transmits a signal for operating each component of the emission device 50 according to the signal is provided (see FIG. 8).

  The first discharge section 52 is provided on the power supply section 525 that supplies power to the first discharge section 52, the holder 521 that holds the paper piece P, the leaf spring 522 that is fixed to the base portion 54, and the upper portion of the leaf spring 522. , A drive motor 524 that is driven based on a drive signal transmitted from the discharge device control device 51 and a paper piece P that is held by the holder 521 and that protrudes from the drive motor 524 And a pickup roller 523 that rotates about the axis as a rotation axis.

  The holder 521 holds a paper piece P having a predetermined size. In this embodiment, it is assumed that a bill-size paper piece can be held. Further, the holder 521 can be appropriately replaced according to the size of the paper piece P to be discharged. The front portion of the holder located on the pickup roller 523 side in the holder 521 is formed with a height that does not prevent the pickup roller 523 from contacting the paper piece P. For example, as shown in FIG. 7, the front surface portion of the holder extends to a height approximately half the height of the paper piece P.

  The drive motor 524 is driven on the basis of a signal indicating drive from the remote controller 70 received by the discharge device control device 51, and transmits drive force via a drive shaft protruding from the drive motor 524. That is, the drive motor 524 rotates the pickup roller 523 in the clockwise direction in FIG. 7 via the drive shaft. Further, the drive motor 524 provided in the leaf spring 522 receives a force on the left side in FIG. 7 by the urging force of the leaf spring 522.

  The pickup roller 523 has a frictional force on the surface since the elastic member is coated on the surface. Accordingly, the pickup roller 523 is provided so as not to slide with the paper piece P provided by the frictional force of the surface. Further, since the drive motor 524 receives force from the leaf spring 522 fixed to the base 54 in the left direction in FIG. 7, the pickup roller 523 having the drive shaft of the drive motor 524 as the rotation shaft is attached to the leaf spring 522. Under the influence of the force, the paper piece P held by the holder 521 is abutted with an appropriate strength. As a result, the pickup roller 523 can discharge the paper pieces P to be placed upward so as to be sequentially hooked up.

  As described above, in the first discharge unit 52, the drive motor 524 is driven based on the signal to drive from the discharge device controller 51, and the pickup roller 523 is rotated by the drive of the drive motor 524, As the pickup roller 523 rotates, the paper piece P placed against the pickup roller 523 is hooked and sequentially discharged upward (clockwise in FIG. 7).

  The second discharge unit 53 has a configuration similar to that of the first discharge unit 52 described above, and is configured symmetrically with respect to the control device 51 for the discharge device. Is omitted. Note that members corresponding to the members of the first discharge unit 52 are denoted by reference numerals corresponding to the power supply unit 535, the holder 531 to be held, the leaf spring 532, the drive motor 534, and the pickup roller 533.

  The discharge device control device 51 receives two types of signals from the remote controller 70. One is a signal for driving the first emission part 52, and the other is a signal for driving the second emission part 53. Therefore, the control device 51 for the emission device receives the signal transmitted from the remote controller 70, receives the received signal by distinguishing whether the received signal is the first emission portion 52 or the second emission portion 53, and receives the corresponding signal. It is transmitted to either the first discharge part 52 or the second discharge part 53 and driven. The discharge device control device 51 can also receive a plurality of signals simultaneously.

  FIG. 8 is a block diagram showing an electrical configuration of the push-up device 40, the discharge device 50, and a remote controller 70 described later. A dashed line in FIG. 8 indicates a path of a signal to be transmitted and received, and a direction in which an arrow of the dashed line is directed indicates a direction in which a signal is transmitted.

  The remote controller 70 includes a remote controller control unit 71 that controls each component included in the remote controller 70, an operation unit 73 that receives a request from the operator, and a remote controller that transmits the request received by the operation unit 73 to the push-up device 40 and the discharge device 50. A transmission unit 72.

  As shown in FIG. 9, the remote controller 70 has an operation unit 73 including three buttons, a button 73a, a button 73b, and a button 73c. For this reason, when the operator presses the button 73a, a signal to drive the push-up device 40 (hereinafter referred to as “signal D1”) is transmitted to the transmission / reception unit 41b of the push-up device 40, and when the button 73b is pressed, A signal to drive the first discharge unit 52 (hereinafter referred to as “signal D2”) is transmitted to the transmission / reception unit 51b of the control device 51 for the discharge device, and the second discharge unit 53 is driven when the button 73c is pressed. (Hereinafter, referred to as “signal D3”) is transmitted to the transmission / reception unit 51b of the control device 51 for the emission device. The push-up device 40 and the discharge device 50 that have received the signal D1, the signal D2, and the signal D3 transmitted from the remote controller 70 are provided with the drive motor 42a, the drive motor 524, and the drive motor, respectively, based on the received signals. 523 is driven.

  Next, the operation of the mirror opening device will be described with reference to FIG.

  First, as shown in FIG. 10A, the mirror opening device is in a state where the mirror lid 1 is not open (see FIG. 10A).

  Here, the operator presses the button 73a of the remote controller 70. Then, a signal D1 for driving the push-up device 40 is transmitted from the remote controller 70 to the transmission / reception unit 41b of the push-up device control device 41. Upon receiving the signal D1, the push-up device control device 41 drives the drive motor 42a of the push-up device drive unit 42 based on the signal D1 to rotate the lift member 42c. As a result, the lower end portion 43b provided on the lift member 42c is lifted upward, and the push-up member 43 is raised. Then, the push-up portion 43a of the push-up member 43 pushes up the inner plate members 1b and 1c of the mirror lid 1 from below. When the pushing-up force is applied to the inner plate members 1b and 1c, the inner plate members 1b and 1c are rotated upward, and the mirror lid 1 is opened by the elastic force of the elastic members 6a and 6b (FIG. 10B). )reference).

  Next, in order to open the mirror lid 1, the button 73b of the remote controller 70 is pressed. Then, a signal D2 for driving the first emission unit 52 of the emission device 50 is transmitted from the remote controller 70 to the transmission / reception unit 51b of the emission device control device 51. Upon receiving the signal D2, the discharge device control device 51 drives the drive motor 524 of the first discharge unit 52 and rotates the pickup roller 523 based on the signal D2. As a result, the paper pieces P placed on the pickup roller 523 are hooked up by the frictional force on the surface of the pickup roller 523 and are sequentially discharged upward, so that the paper pieces P fly in the air (see FIG. 10C). The rotation speed of the pickup roller 523 is about 4000 to 5000 rotations per minute, and preferably about 4500 rotations per minute.

  Further, as described above, the operator may press the button 73c together with the button 73b after pressing the button 73a. By doing so, similarly to the operation of the first discharge section 52, the second discharge section 53 is driven, and the paper pieces P can be discharged simultaneously sequentially upward. That is, since the first discharge unit 52 and the second discharge unit 53 can be driven at the same time, for example, different types of paper can be discharged simultaneously from the first discharge unit 52 and the second discharge unit 53. . For example, if the paper piece P to be released at this time is a paper piece imitating money or a red and white paper piece, the appearance is more luxurious.

  As described above, by opening the mirror lid and discharging a plurality of paper pieces from the opening of the barrel frame member, the plurality of discharged paper pieces fly in the air, and it is possible to realize an effect different from a normal mirror opening. . Accordingly, it is possible to realize a mirror opening that can visually attract people who are participating in the event in which the mirror opening device is used.

  In the embodiment described above, the elastic members 6a and 6b in the lens cover 1 are not limited to those described above. For example, an elastic member as shown in FIGS. 11 and 12 may be used. In the following description, description and illustration of the same points as those described in the above embodiment will be omitted, and only different points will be described.

  For example, the lens cover 10 shown in FIG. 11 includes elastic members 11a, 12a, 13a, and 14a. The elastic members 11a and 12a are flat surfaces of the lens lid 10 so as to connect the fixing members 11b and 12b provided on the upper surface of the outer plate member 1a and the fixing members 11c and 12c provided on the upper surface of the inner plate member 1b.

It is provided in a state having a predetermined elastic force (tension) in 10 plane directions. Thus, similarly to the above-described embodiment, by providing the elastic members 11a, 12a, 13a, and 14a in a state having a predetermined elastic force in the plane direction, the inner plate members 1b and 1c can be opened in a double-tone manner.

  Moreover, as shown in FIG. 12, the mirror cover 20 has elastic members 21a, 22a, 23a, and 24a. The elastic members 21a and 22a connect the fixing members 21b and 22b provided on the side surface of the outer plate member 1a and the fixing members 21c and 22c provided on the side surface of the inner plate member 1b, respectively. Are provided in a state having a predetermined elastic force.

As described above, each end has a predetermined length, one end is tied to the mallet 80, the other end is passed between the inner plate member 1b and the inner plate member 1c, and the tip is bifurcated. A mirror opening device using a transparent string member 81 connected to the stopper member 5a of the plate member 1b and the stopper member 5b of the inner plate member 1c may be used. In this case, an operator handling the wooden mallet 80 quickly pulls up the wooden mallet 80 after hitting a desired position of the mirror lid 82 with the wooden mallet 80. At this time, the pulled wooden mallet 80 is pulled away so that the distance from the stopper members 5a and 5b is longer than the length of the string member 81. By doing so, the stopper portions 5a and 5b to which the string member 81 is connected are pulled up. That is, since a force from the lower side to the upper side is applied to the inner side plate members 1b and 1c, the mirror lid 1 can be opened by a person (operator).

  Further, the operation of the push-up device 40 and the release device 50 in the mirror opening device has been described as being performed from the remote controller 70 by the operator. However, the operation of the push-up device 40 and the release device 50 is not limited to this, and the operation of the remote control timer or the like Thus, it may be controlled in time. In this way, for example, if the time is set in advance by a timer, a signal to drive the discharge device 50 may be automatically transmitted after transmitting a signal to drive the push-up device 40 from the remote controller 70. it can.

  Moreover, although the pushing-up apparatus 40 and the discharge | release apparatus 50 provided in the inside of the barrel frame member 31 demonstrated the case where it was mounted on the bottom face of the barrel frame member 31, not only this but the barrel frame member 31 of An intermediate plate for raising the bottom may be provided, and the push-up device 40 and the discharge device 50 may be placed thereon. By doing so, the discharge position of the discharge device 50 becomes higher, so that the discharged paper piece is raised higher.

  Moreover, although the case where the inner side plate members 1b and 1c are pushed up by a member having a shape such as the push-up member 43 has been described, the present invention is not limited to this and may be pushed up by wind pressure.

  In addition, although the mirror cover 1 is composed of four sheets, it may be composed of five or more sheets.

  The inner plate members 1b and 1c rotate on the upper side of the lens cover 1 when an external force is applied upward, but rotate on the lower side of the lens cover 1 when an external force is applied on the lower side. It is good.

  Moreover, although the case where three hinges are provided to connect the outer member 1a and the inner member 1b and the outer member 1d and the inner member 1c each is described, the hinge is not limited to this. Two or four or more may be used.

  Moreover, although the case where there is one push-up member 43 in the push-up device 40 has been described, the present invention is not limited thereto, and a plurality of push-up members 43 may be used. In this case, the inner plate members 1b and 1c are both pushed up at the same time.

  Moreover, although the transmission / reception unit 41b of the push-up device 40 and the transmission / reception unit 5b of the release device 50 have been described with respect to the case where signals are transmitted and received wirelessly with the remote controller 70, the present invention is not limited thereto, and signals may be transmitted and received by wire. .
