  The present invention relates to a swing-type light-emitting display device that displays a symbol on a swing locus of a bar-shaped member on which a plurality of light-emitting elements are arranged by using light emission afterimages of the plurality of light-emitting elements.

  In this type of swing-type light emitting display device, a plurality of light emitting elements are controlled by the light emission control unit so that a pattern can be displayed when the rod-shaped member is swung, and the light emission patterns of the plurality of light emitting elements are switched every minute time. (See Patent Documents 1 and 2). In the swing-type light-emitting display devices of Patent Documents 1 and 2, a plurality of light-emitting elements that can display the same or different symbols for the forward and backward swings when the rod-shaped member is swung to reciprocate.

  In the conventional swing type light emitting display device, in the case where the switching order for sequentially switching a plurality of light emitting patterns and the switching time cannot be adjusted and controlled, a bar shape is used so that characters such as characters are properly displayed by the light emission afterimages of the plurality of light emitting elements. It is difficult to swing the member. In other words, since the plurality of light emitting elements are controlled so as to achieve the predetermined switching order and switching time, when the rod-shaped member is swung, the swing direction of the rod-shaped member is opposite to the normal direction. In many cases, characters are displayed in reverse video.

  For example, when the rod-shaped member is swung in the normal direction, as shown in FIG. 5, when the character “SKE” is displayed, when the swing direction of the rod-shaped member is opposite to the normal direction, FIG. As shown, the reverse character of “SKE” is displayed.

  In the swing-type light emitting display device of Patent Document 2, when a bar-like member is swung in accordance with the performance tempo output from the speaker, characters are displayed neatly in one swing, that is, depending on the tempo of this performance. The timing for switching the swing direction of the rod-shaped member is notified. However, the normal swing direction of the bar-shaped member cannot be known except by looking at the actually displayed pattern. Therefore, the swing direction of the bar-shaped member is opposite to the normal direction, and the characters are displayed in reverse video. The problem of increasing the number of cases is not improved.

  In the swing-type light-emitting display device of Patent Document 1, characters are appropriately displayed in a normal size that does not invert with an appropriate size for each swing according to the swing direction and swing speed of the bar-shaped member detected by the angular velocity detector. As described above, the switching order for sequentially switching a plurality of light emission patterns and the switching time are adjusted and controlled. However, it is difficult to accurately detect and control the swing direction and swing speed of the rod-shaped member, and to accurately adjust and control the switching order and switching time. In addition, the load for controlling a plurality of light emitting elements is increased, and angular velocity detection is performed. Since it is necessary to provide a separate vessel, the manufacturing cost increases.

(First to thirteenth LEDs 3a to 3m) and a light emission control device 4 (light emission control means) for controlling the plurality of LEDs 3 so that the symbols can be displayed by the light emission afterimages of the plurality of LEDs 3 on the swing locus when the rod-like member 2 is swung. 4).

  As shown in FIGS. 1 to 3, the rod-shaped member 2 is composed mainly of a synthetic resin material, and includes an LED mounting tube portion 2 a to which a plurality of LEDs 3 are mounted, and a grip tube portion 2 b that can be held by hand. Have The plurality of LEDs 3 are arranged at equal intervals and mounted on, for example, one strip-shaped substrate, and this substrate is fixed inside the LED mounting cylinder portion 2a. A plurality (13) of holes are formed in the LED mounting cylinder portion 2a at equal intervals in the length direction of the rod-like member 2, and a plurality of LEDs 3 face the outside from the plurality of holes.

  The number of LEDs 3 is 13 in this embodiment, but is not limited thereto. About the luminescent color of several LED3, it is preferable that it is fundamentally all set to the same color (for example, blue). However, a plurality of colors can be mixed. In this case, three LEDs having different emission colors are arranged in a group to form one set, and the three LEDs are arranged in the length direction of the plurality of sets of rod-shaped members 2. May be. Various light emitting elements can be applied instead of the LED 3. Without forming the plurality of holes in the LED mounting tube portion 2a, the LED mounting tube portion 2a is made transparent (or translucent), and light emitted from the LED 3 provided inside the LED mounting tube portion 2a is transmitted to the outside. May be.

  As shown in FIGS. 1 to 4, the grip tube portion 2 b is provided with a power supply operation portion 5 that can be operated by a person using the swing type light emitting display device 1 (hereinafter referred to as a user). First and second notification LEDs 6a and 6b, which are first and second notification lights that are visible even when the user swings the rod-shaped member 2 by hand, are attached to the bottom portion 2c of the portion 2b. ing. These first and second notification LEDs 6a and 6b are each covered with a transparent or translucent cover in order to avoid external exposure. The grip cylinder portion 2b is formed with a card insertion slot 2d for inserting a memory card 7 (hereinafter referred to as MC7).

  The power supply operation unit 5 is, for example, a slide operation type that slides in a direction parallel to the length direction of the rod-like member 2, but may be a push operation type. The first and second notification LEDs 6a and 6b may be attached to the grip cylinder 2b instead of the bottom 2c. However, in this case, the first and second notification LEDs 6a and 6b are prevented from interfering with the user's hand having the grip cylinder portion 2b. The light emission colors of the first and second notification LEDs 6a and 6b may be the same color (for example, white) or different colors (for example, white and red).

  As shown in FIG. 4, in the grip cylinder portion 2b, in addition to the light emission control device 4, an LED drive circuit 8 for driving a plurality of LEDs 3 and first and second notification LEDs 6a and 6b, for MC7 A power supply circuit 10 that supplies power to the memory card reader (hereinafter referred to as MC reader 9), the light emission control device 4, the LED drive circuit 8, and the MC reader 9 is provided.

  The light emission control device 4 reads various data stored in the MC 7 via the MC reader 9 and, based on the various data, a plurality of LEDs 3 (first to thirteenth LEDs 3a to 3m) via the LED drive circuit 8. The first and second notification LEDs 6a and 6b are driven and controlled. The power supply circuit 10 includes a power supply SW 10 a that is operated via the power supply operation unit 5 to switch the power supply on and off, and a replaceable or rechargeable battery 10 b (for example, several commercially available batteries).

  By the way, when the user swings the rod-shaped member 2 by holding the grip cylinder portion 2b by hand, the plurality of LEDs 3 are substantially orthogonal to the swing surface of the rod-shaped member 2 and in a direction opposite to the user (usually in front of the user). This is the normal swing direction S of the rod-shaped member 2, and the correct swing method is to swing the rod-shaped member 2 left and right perpendicular to the length direction. Thereby, for a person who can see the swing of the rod-shaped member 2 from the side opposite to the user (hereinafter referred to as “other”), the symbols and the like are displayed by the swing of the rod-shaped member 2.

  When the light emission control device 4 swings the rod-like member 2 so as to reciprocate in the normal swing direction S, the forward swing S1 and the backward swing S2 have the same pattern (for example, “SKE” shown in FIG. 5). Are controlled so that the light emission patterns of the plurality of LEDs 3 are switched at set times, and the light emission patterns are sequentially switched in the forward swing S1. The switching order for switching and the switching order for sequentially switching a plurality of light emission patterns in the backward swing S2 are reversed.

  In this swing type light emitting display device 1, the swing direction of the bar-shaped member 2 that can display a symbol in synchronization with control by the light emission control device 4 (control to switch the light emission pattern of the plurality of LEDs 3 at every set time). Timing to switch the swing direction of the swing direction guide means 11 for notifying the forward swing S1 and the backward swing S2 and the swing direction of the bar-shaped member 2 that can display the symbol from one of the forward swing S1 and the backward swing S2 to the other. And a timing guide means 12 for informing the above.

  The swing direction guide means 11 is attached to the rod-shaped member 2 and corresponds to the forward swing S1 and the backward swing S2 of the rod-shaped member 2, and the first and second notification LEDs 6a, 6b, The first and second notification LEDs 6a and 6b are attached to the rod-like member 2 so as to indicate the corresponding swing directions (forward swing S1 and backward swing S2), respectively. Yes.

  The first and second notification LEDs 6a and 6b are attached to the bottom 2c of the grip cylinder 2b. Specifically, in the vicinity of the outer periphery of the bottom 2c, the direction of the forward swing S1 from the center of the rod-like member 2 The first notification LED 6a is attached on the line, and the second notification LED 6b is attached on the direction line of the backward swing S2 from the center of the rod-like member 2. The notification of the forward swing S1 is performed by turning on the first notification LED 6a and turning off the second notification LED 6b while the forward swing S1 is to be performed. The notification of the backward swing S2 is performed by the backward swing S2. Is performed with the first notification LED 6a turned off and the second notification LED 6b turned on.

  The timing guide means 12 is configured to serve also as the first and second notification LEDs 6a and 6b, that is, the light emission control device that controls the first and second notification LEDs 6a and 6b and the first and second notification LEDs 6a and 6b. 4. The notification for switching from the forward swing S1 to the backward swing S2 is performed by switching the second notification LED 6b from the unlit state to the lit state (the first notifying LED 6a is switched from the lit state to the unlit state). The notification to switch to the forward swing S1 is performed by switching the first notification LED 6a from the unlit state to the lit state (the second notification LED 6b from the lit state to the unlit state).

Processing and control executed by the light emission control device 4 will be described in detail.
As shown in FIG. 6, this processing / control is started when the power is turned on. First, initial setting (S1) is executed, where 1 is set to the light emission pattern number n and 0 is set to the measurement time t. Set. Thereafter, various data are read from the MC 7 attached to the MC reader 9 (S2), and then it is determined whether or not the light emission control is started (S3). Here, the process waits until the determination of S3 becomes Yes. . Note that if the MC 7 is not attached to the MC reader 9 or if the data necessary for light emission control is not read from the MC 7 even if the MC 7 is attached, an error occurs and the light emission control is not started.

  Here, as shown in FIG. 7, MC7 includes data of a plurality of light emission patterns (first light emission pattern P1, second light emission pattern P2,..., Nth light emission pattern PN (N = 19)), light emission patterns. Number N (N = 19) data, light emission pattern switching time ΔT data, reciprocating same symbol designating data, and the like are stored.

  For example, the plurality of light emission patterns P1 to P19 display the characters “SKE” as shown in FIG. 8 in both the forward swing S1 and the backward swing S2. Among the light emission patterns P1 to P19, for example, in the first light emission pattern P1, all the LEDs 3 are turned off, and in the second light emission pattern P2, the LEDs 3b to 3f and 3l are turned on and the remaining LEDs 3 are turned off, and the fifth light emission pattern. In P5, the LEDs 3a, 3g, and 3m are turned on and the remaining LEDs 3 are turned off. In the eighth light emission pattern P8, all the LEDs 3 are turned on.

  The data of each light emission pattern is data for designating the LED 3 to be turned on with the light emission pattern. However, the data of each light emission pattern may be accompanied by data of the lighting time of the LED 3 that is turned on with the light emission pattern (this lighting time is equal to or shorter than the light emission pattern switching time ΔT).

  The number N of light emission patterns is the number of light emission patterns stored in the MC 7, and the light emission pattern switching time ΔT is the time from when the light emission pattern is switched to when the next light emission pattern is switched. The reciprocating same symbol designation means designation to display the same symbol in the forward direction swing S1 and the backward direction swing S2, and on the condition that the data of this reciprocating identical symbol designation has been read, the steps after S4 in FIG. Light emission control is enabled.

  Based on various data read from the MC 7, the light emission control after S4 is executed, so that the user swings the rod-like member 2 according to the guides by the swing direction guide means 11 and the timing guide means 12. As shown in FIG. 5, a desired character (“SKE”) is appropriately displayed.

  It is to be noted that a personal computer is used, and the personal computer is configured so that the MC 7 is mounted on the MC light reader, and various data as shown in FIG. 7 is downloaded from a predetermined site on the Internet and stored in the MC 7. it can. Further, various data as shown in FIG. 7 may be configured to be original editable using a personal computer.

  As shown in FIG. 6, when data necessary for light emission control is read from the MC 7 and the determination in S3 is Yes, first, the forward swing flag F is set to 1 (S4), and then The first notification LED 6a is turned on, the second notification LED 6b is turned off (S5), and then the plurality of LEDs 3 (first to thirteenth LEDs 3a to 3m) are switched to the nth light emission pattern (S6). In the first S6 after the power is turned on, since 1 is set to n in the initial setting of S1, the first light emission pattern P1 is switched. The user may look at the lit first notification LED 6a and perform the forward swing S1 that is the direction indicated by the first notification LED 6a.

  By executing S6, the LED 3 to be lit is turned on for a time equal to or shorter than the light emission pattern switching time ΔT, and this lighting time is determined based on the light emission time data attached to the light emission pattern data read from the MC 7. May be. After execution of S6, the measurement time t is started from 0 (S7), and then it is determined whether measurement time t ≧ light emission pattern switching time ΔT (S8), and waits until the determination of S8 becomes Yes. Is done.

  If the determination in S8 is Yes, 0 is set to the measurement time t (S9), and then it is determined whether or not the forward swing flag F = 1 (S10). At the forward swing S1, the determination at S10 is Yes, and then it is determined whether or not the light emission pattern number n = N (N = 19) (S11). If the determination at S11 is No, that is, the forward swing. When S1 is continuously performed, the light emission pattern number n is added to n + 1 (S12), and the process returns to S6. Thus, until the determination in S11 becomes Yes, as shown in FIG. 8, at the time of forward swing S1, the light emission patterns of the plurality of LEDs 3 are set at every set time ΔT such that P1 → P2 → P3. Are sequentially switched.

  When the determination in S11 is Yes, that is, when switching from the forward swing S1 to the backward swing S2, the process proceeds to S13. In S13, the forward direction swing flag F is set to 0, then the first notification LED 6a is turned off, the second notification LED 6b is turned on (S14), and then a plurality of LEDs 3 (first to thirteenth LEDs 3a to 3m). Are switched to the nth emission pattern (S6). If the determination in S11 is Yes, the light emission pattern number n (= 19) is maintained and S6 is executed, that is, the Nth (N = 19) light emission pattern is the same as the previous time, and the light emission pattern is not switched as a result. . The user may look at the lit second notification LED 6b and perform a backward swing S2 in the direction indicated by the second notification LED 6b.

  Thereafter, S7 to S10 are executed in the same manner as described above, and in the case of backward swing S2, the determination in S10 is No, then it is determined whether or not the light emission pattern number n = 1 (S15), and the determination in S15 is No That is, when the backward swing S2 is continuously performed, the light emission pattern number n is subtracted from n-1 (S16), and the process returns to S6. Thus, until the determination of S15 becomes Yes, as shown in FIG. 8, at the time of backward swing S2, the light emission patterns of the plurality of LEDs 3 are set at every set time ΔT such that P19 → P18 → P17. Are sequentially switched.

  When the determination in S15 is Yes, that is, when switching from the backward swing S2 to the forward swing S1, the process proceeds to S4. In S4, as described above, 1 is set to the forward direction swing flag F, then the first notification LED 6a is turned on, the second notification LED 6b is turned off (S5), and then the plurality of LEDs 3 (first to third LEDs 1) The thirteenth LEDs 3a to 3m) are switched to the nth light emission pattern (S6). If the determination in S15 is Yes, the light emission pattern number n (= 1) is maintained and S6 is executed, that is, the first light emission pattern is the same as the previous time, and as a result, the light emission pattern is not switched. The user may look at the lit first notification LED 6a and perform the forward swing S1 that is the direction indicated by the first notification LED 6a. Thereafter, processing and control are executed in the same manner as described above.

The swing-type light emitting display device 1 described above has the following effects.
The light emission control device 4 controls the plurality of LEDs 3 so that the same symbol can be displayed by the forward swing S1 and the backward swing S2 when the rod-like member 2 is swung to reciprocate. In synchronization with the control, the swing direction guide means 11 for notifying the swing direction of the bar-shaped member 2 that can display the symbol, and the timing guide means 12 for notifying the timing for switching the swing direction of the bar-shaped member 2 that can display the symbol. Was provided.

  Accordingly, the user makes the plurality of LEDs 3 face substantially orthogonal to the swing surface of the rod-like member 2 and in the opposite direction to the user (usually in front of the user), and the swing direction guide means 11 and the timing guide means. By swinging the rod-shaped member 2 in accordance with the notification by 12, it is possible to appropriately display the symbol (“SKE”) to the other person as shown in FIG. 5 by the light emission afterimages of the plurality of LEDs 3 on the swing locus. it can.

  That is, by guiding the swing direction of the rod-shaped member 2 by the swing direction guide means 11, the characters can be displayed in the normal direction as shown in FIG. 5 without being reversed as shown in FIG. By guiding the timing of switching the swing direction of the rod-shaped member 2 by the timing guide means 12, it is possible to display characters in an appropriate size by one swing (forward swing S1 or backward swing S2).

  The swing direction guide means 11 has first and second notification LEDs 6a and 6b that are attached to the rod-shaped member 2 and correspond to the forward swing S1 and the backward swing S2 of the rod-shaped member 2, respectively. By controlling the LEDs 6a and 6b and turning on the notification LED 6a or 6b corresponding to the direction to be swung, it is possible to reliably notify the swing direction of the bar-shaped member 2 that can display the symbol. In addition, since the first and second notification LEDs 6a and 6b are attached so as to indicate the corresponding swing directions, respectively, by swinging the rod-like member 2 in the direction indicated by the lit notification LED 6a or 6b, characters are displayed. A swing that is displayed in a normal orientation can be easily realized.

  Since the timing guide means 12 is configured to also serve as the first and second notification LEDs 6a and 6b of the swing direction guide means 11, it is not necessary to provide a separate notification device for the timing guide, that is, the structure is complicated. The timing of switching the swing direction of the rod-like member 2 can be notified by suppressing the manufacturing cost from increasing.

  The light emission control device 4 controls the light emission patterns of the plurality of LEDs 3 to be switched every set time, and the switching order P1 → P2 →... → P19 for sequentially switching the light emission patterns P1 to P19 in the forward direction swing S1. Since the switching order P19 → P18 →... → P1 for sequentially switching the plurality of light emission patterns P1 to P19 in the backward swing S2 is reversed, the data amount of the plurality of light emission patterns P1 to P19 is reduced to a bar shape. The same symbol can be displayed on the forward swing S and the backward swing S2 of the member 2.

  The second embodiment is a partial modification of the first embodiment. Therefore, the description of the structure, configuration, and functions that are basically the same as those of the first embodiment will be omitted.

  When the light emission control device 4 swings the rod-like member 2 so as to reciprocate in the normal swing direction S, the forward swing S1 and the backward swing S2 have different patterns (for example, the forward swing S1 shown in FIG. 5). A plurality of LEDs 3 are controlled such that the characters “SKE” in FIG. 11 and the characters “No. 1” in the backward swing S2 shown in FIG. Control is performed so that the light emission pattern is switched every set time.

Processing and control executed by the light emission control device 4 will be described in detail.
As shown in FIG. 9, this processing / control is started when the power is turned on, and first, S1 to S10 are sequentially executed as in the first embodiment. Here, as shown in FIG. 10, MC7 includes data of a plurality of light emission patterns (first light emission pattern P1, second light emission pattern P2,..., Nth light emission pattern PN (N = 38)), light emission patterns. Number N (N = 38) data, light emission pattern switching time ΔT data, reciprocal non-identical designating data, and the like are stored.

  For example, in the plurality of light emission patterns P1 to P38, the character “SKE” is displayed as shown in FIG. 8 in the forward swing S1, and “No. 1” is displayed in the backward swing S2 as shown in FIG. Characters are displayed, and the light emission patterns P1 to P19 are the same as the light emission patterns P1 to P19 of the first embodiment.

  Among the light emission patterns P20 to P38, for example, in the 22nd light emission pattern P22, all the LEDs 3 are turned on, in the 28th light emission pattern P28, the LEDs 3g to 3l are turned on, the remaining LEDs 3 are turned off, and in the 35th light emission pattern P35. The LED 3g is turned on and the remaining LEDs 3 are turned off. The reciprocal non-identical symbol designation means designation for displaying different symbols for the forward swing S1 and the backward swing S2, and after S4 in FIG. The light emission control is enabled.

  As shown in FIG. 9, in S10, it is determined whether or not the forward swing flag F = 1. In the forward swing S1, the determination in S10 is Yes, and then the light emission pattern number n = N / 2. Whether or not (N = 38) is determined (S21), and if the determination of S21 is No, that is, when the forward swing S1 is continued, the light emission pattern number n is added to n + 1 (S22), and the process proceeds to S6. Return. Thus, until the determination of S21 is Yes, as shown in FIG. 8, at the time of forward time swing S1, the light emission patterns of the plurality of LEDs 3 are set at every set time ΔT such that P1 → P2 → P3. Are sequentially switched.

  When the determination in S21 is Yes, that is, when switching from the forward swing S1 to the backward swing S2, the light emission pattern number n is added to n + 1 (S23), and the process proceeds to S13. Thereafter, during the backward swing S2, the determination of S10 is No, and then it is determined whether or not the light emission pattern number n = N (N = 38) (S24). If the determination of S24 is No, the process proceeds to S22. Then, the process returns to S6. Thus, until the determination in S24 becomes Yes, as shown in FIG. 11, at the time of backward swing S2, the light emission patterns of the plurality of LEDs 3 are set at every set time ΔT such that P20 → P21 → P22. Are sequentially switched. When the determination in S24 is Yes, that is, when switching from the backward swing S2 to the forward swing S1, 1 is set to the light emission pattern number n (25), and the process proceeds to S4.

  According to the swing-type light emitting display device 1 of the second embodiment, the light emission control device 4 can display different symbols for the forward swing S1 and the backward swing S2 when the rod-like member 2 is swung so as to reciprocate. The plurality of LEDs 3 are controlled. Therefore, the user swings the rod-shaped member 2 according to the notification by the swing direction guide unit 11 and the timing guide unit 12, so that the light emission afterimages of the plurality of LEDs 3 are on the swing locus. As shown in FIGS. 5 and 11, the symbols (“SKE” and “No. 1”) can be appropriately displayed to others. The other effects are the same as those of the swing-type light emitting display device 1 of the first embodiment.

  The swing direction guide means 11 and the timing guide means 12 may be notified by sound or vibration instead of the notification LEDs 6a and 6b or in combination with the notification LEDs 6a and 6b. For example, when notifying by vibration, a vibrator is provided in the grip cylinder portion 2b of the rod-like member 2, and the notification is made by operating and vibrating one of the forward swing S1 and the backward swing S2, and the forward direction. The notification is made by not activating the vibrator on the other side of the swing S1 and the backward swing S2 so as not to vibrate.

  In addition, various modifications can be added and implemented without departing from the spirit of the present invention. For example, the rod-shaped member 2 (LED mounting cylinder portion 2a, grip cylinder portion 2b) can be applied in various structures.
