  By the way, the mechanism that “sounds when the lid is opened” is aimed at enhancing the “directivity” of entertainment products such as CDs and DVD products and inspiring consumers to purchase, but the music that is generated, etc. If the “Gimmick” is the same every time, the buyer may get bored. On the other hand, when a sound is generated every time the case lid is opened, it may be assumed that the purchaser feels annoying or annoying.

  Furthermore, an optical sensor, a speed sensor, or the like may be used when detecting the opening / closing of the lid that triggers the occurrence of a gimmick. However, in order to operate the sensor, it is necessary to pass a current little by little even while the lid is closed. Therefore, when applied directly to a media case such as a CD or DVD, current continues to flow through the sensor or the like even during storage in a warehouse or at a store. Then, when the storage period or display period is long (for example, half a year), the battery as the energy source is completely discharged, and a “gimmy” does not occur when the purchaser purchases the CD or DVD. Can happen.

  The present invention pays attention to the above points, and an object of the present invention is to improve the production effect by the gimmick so that it can be enjoyed repeatedly. Another object is to prevent unnecessary battery consumption and to generate a good gimmick at the time of purchase.

  In order to achieve the above object, the present invention includes sensor means for detecting an external action, gimmick generating means for generating a gimmick when the action is detected, and power supply means for supplying driving power to each part. A media case, comprising: gimmick changing means for changing the contents of the gimmick generated by the gimmick generating means in response to detection by the sensor means.

  One of the main forms is characterized in that the sensor means detects an action related to opening and closing of the lid of the media case. One of the other forms is characterized in that the gimmick generating means generates at least one gimmick that can be sensed by human senses. Yet another embodiment is characterized in that the gimmick generating means generates a plurality of types of gimmicks. Yet another embodiment is characterized in that the gimmick generating means generates one kind of gimmick by changing the mode. Yet another embodiment is characterized in that the power supply means includes means for starting the supply of drive power when detection is made by the sensor means. Alternatively, the power supply means includes means for completely stopping the supply of drive power. Yet another embodiment is characterized in that the gimmick changing means changes the contents of the gimmick in response to detection by a plurality of sensor means. The above and other objects, features and advantages of the present invention will become apparent from the following detailed description and the accompanying drawings.

  According to the present invention, when the action from the outside is detected and the gimmick is generated thereby, the contents of the gimmick change, so that the production effect is improved and can be enjoyed repeatedly.

The image signal generation circuit 150 is a circuit that generates an image signal based on input data, and the generated image signal is reproduced and output as an image on the display body 152.

  FIG. 3 shows a state in which the gimmick generating device 100 shown in FIG. 2 is attached to the disk case 10 shown in FIG. The illustrated example includes an open / close sensor 202 in the sensor group 200, and includes an audio signal generation circuit 120 and a sounding body 122 as the gimmick generation means 104. The power source 106, the main switch 108, the open / close sensor 202, the detection identification circuit 220, the gimmick data extraction circuit 110, and the audio signal generation circuit 120 are housed in appropriate positions in the gap formed between the case body 12 and the disk tray 14. ing. Among these, the open / close sensor 202 is provided at a position where the ON / OFF operation can be performed in accordance with the opening / closing of the lid 13. The longitudinal section is shown in FIG. As shown in the figure, the open / close sensor 202 is provided on a substrate 202A, and includes a fixed piece 202B and a slide piece 202C that can slide in the direction of arrow F1. One end of the fixed piece 202B is fixed on the substrate 202A, and the other end can contact the slide piece 202C. On the other hand, the slide piece 202 </ b> C is configured to slide in conjunction with opening and closing of the lid 13. Thereby, the fixed piece 202B and the slide piece 202C are in an electrically non-contact OFF state when the lid 13 is closed, and conversely, when the lid 13 is opened, they are in an electrically contacted ON state. . Thereby, opening / closing of the lid 13 is detected.

  Such an open / close sensor 202 is connected to the detection identification circuit 220. For example, each time the opening / closing sensor 202 detects the opening of the lid 13, the detection identification circuit 220 operates by the counter 224 and stores the count value in the set value memory 222. The set value memory 222 is configured by a non-volatile memory such as a flash memory, and the count value is stored even when the supply of power is interrupted. The radio timepiece 226 will be described later.

  On the other hand, the count value of the detection identification circuit 220 is output to the gimmick data extraction circuit 110. The gimmick data extraction circuit 110 includes a plurality of gimmick data as a data list 112 and has a function of extracting gimmick data corresponding to an input count value from the data list 112. The extracted gimmick data is supplied to the audio signal generation circuit 120, where a corresponding audio signal is generated and supplied to the sound generator 122.

  The sounding body 122 is provided in the clamper 20 of the disk tray 14. FIG. 1C shows a cross section viewed in the direction of the arrow along the line # B- # B in FIG. As shown in the figure, the clamper 20 is constituted by a central convex portion 20A and a peripheral pedestal portion 20B. Further, the convex portion 20A is provided with an opening 20C and a slit 20D. A sounding body (speaker) 122 is fixed in the pedestal portion 20B by, for example, a ring-shaped double-sided tape or an adhesive 122A. Furthermore, in this embodiment, a ring-shaped seal 40 is provided around the sounding body 122 by double-sided tape or hot melt. As a result, a closed space or an air chamber 40 </ b> A is formed between the case body 12 and the disk tray 14 on the back side of the sound generator 122. A lead wire 122B that supplies an audio signal from the audio signal generation circuit 120 to the sounding body 122 passes through the seal 40 and is connected to the terminal 122C of the sounding body 122.

  Next, the operation of this embodiment will be described. In the disc case 10, the DVD is stored in the storage tray 16 in the disc tray 14. In this state, the main switch 108 is OFF, and power is not supplied to each part. Then, when purchasing a DVD, the main switch 108 is switched from OFF to ON by a store clerk or the purchaser himself. Then, it will be in the state in which the electric power supply from the power supply 106 with respect to each part of the gimmick generator 100 is possible.

  In this state, when the purchaser opens the lid 13 of the disk case 10, this is detected by the open / close sensor 202. When the detection result is supplied to the power supply 106 via the main switch 108, driving power is supplied from the power supply 106 to each part of the gimmick generator, and each part starts operating. When the detection result of the open / close sensor 202 is input to the detection identification circuit 220, the detection identification circuit 220 counts up by “1” using the function of the counter 224. This count value is stored in the set value memory 222 and supplied to the gimmick data extraction circuit 110. The gimmick data extraction circuit 110 extracts gimmick data corresponding to the count value “1” from the data list 112. The extracted gimmick data is supplied to the audio signal generation circuit 120, where an audio signal is generated based on the gimmick data. The generated sound signal is supplied to the sound generator 122 and reproduced and output as sound.

Examples of the gimmick data and its reproduction mode are as follows.
(1) Two musics 1 and 2 are prepared. Music 1 is reproduced when the count value is an odd number, and music 2 is reproduced when the count value is an even number. That is, every time the lid 13 is opened and closed, the music 1 and 2 are repeatedly reproduced alternately.

  (2) Prepare normal music, voice (such as a bird's voice), and sound effects (such as beeps and waves) and play them in sequence each time you count up. That is, every time the lid 13 is opened and closed, it is repeatedly reproduced in the order of music → voice → natural sound (sound effect) → music. Note that music, voice, sound effects, etc. may be recorded actual sounds or may be artificially generated.

  (3) When the DVD stored in the disc case 10 is like a content starring a specific popular group, messages MA, MB,... Of members A, B,. They are played back in sequence at each count-up. That is, each time the lid 13 is opened and closed, messages are reproduced in the order of message A of member A → message MB of member B.

  (4) When the DVD stored in the disc case 10 is a horror movie, prepare a squeaking sound like opening a ruined door that is the stage of the movie. During the operation of opening the lid 13, the squeaking noise is generated. Further, when the lid 13 is closed, a squeaking noise is generated similarly. That is, the rubbing sound of the ruined door is reproduced when the lid 13 is opened and closed. A plurality of itching sounds 1 and 2 may be prepared, and itching sound 1 may be a sound when the lid 13 is opened, and itching sound 2 may be a sound when the lid 13 is closed.

  As described above, the count value is stored / saved in the nonvolatile setting value memory 222. Therefore, even if the purchaser turns off the main switch 108, the count value is stored. For this reason, even when the main switch 108 is turned on again, the count value changes continuously without being reset. Therefore, even if the main switch 108 is turned off, the contents of the gimmick change continuously. It becomes like this. For example, in the example (2), music is repeatedly reproduced in the order of music → voice → natural sound → music → voice → natural sound →.

As described above, according to this embodiment, there are the following effects.
(1) Each time the lid 13 of the disc case 10 is opened and closed, a different gimmick is generated, so that the effect of production is improved and it can be enjoyed repeatedly.
(2) When the DVD is purchased, the main switch is turned on to supply the drive power to each part, so that unnecessary battery consumption can be prevented. In addition, by switching the main switch, it is possible to arbitrarily set the stop and restart of the gimmick generation.

Next, Example 2 will be described. In this embodiment, the light emission signal generation circuit 130 and the light emitter 132, the vibration signal generation circuit 140 and the vibration body 142, the image signal generation circuit 150, and the display body 152 shown in FIG. Of these,
(1) Light emission signal generation circuit 130: a circuit for generating a light emission signal based on the gimmick data supplied from the gimmick data extraction circuit 110,
(2) Vibration signal generation circuit 140: a circuit for generating a vibration signal based on the gimmick data supplied from the gimmick data extraction circuit 110,
(3) Image signal generation circuit 150: a circuit for generating an image signal based on the gimmick data supplied from the gimmick data extraction circuit 110,
It is. Both are provided in the vicinity of the audio signal generation circuit 120 described above.

  The light emitter 132 is configured by a light emitting diode or the like, and is provided at an appropriate position such as the disk tray 14 of the lid 13 or the inside of the lid 13 (not shown). The vibrating body 142 is configured by a piezoelectric element or the like, and is provided at an appropriate position of the case 10 (not shown). The display body 152 is configured by a liquid crystal display or the like, and is provided at an appropriate position of the case 10 (not shown).

  Next, the operation of this embodiment will be described. In the above embodiment, sound is output based on the gimmick data extracted by the gimmick data extraction circuit 110. In this embodiment, the gimmick data is converted into a light emission signal generation circuit. 130, the vibration signal generation circuit 140 and the image signal generation circuit 150 are supplied, and the light emitter 132 emits light, the vibration body 142 vibrates, or an image is displayed on the display body 152.

Examples of gimmick data and its reproduction output modes include the following.
(1) A plurality of emission colors are prepared, and the light emitter 132 emits light of different colors depending on the count value. For example, “blue” and “red” colors are prepared. When the count value is an odd number, “blue” light emission is performed, and when the count value is an even number, “red” light emission is performed.

  (2) A plurality of blinking intervals are prepared, and the light emission interval of the light emitter 132 is changed according to the count value. For example, the blinking interval is shortened when the count value is an odd number, and the blinking interval is increased when the count value is an even number.

  (3) A plurality of vibration frequencies are prepared, and the vibration frequency of the vibrating body 142 is changed according to the count value. For example, when the count value is an odd number, the vibration frequency is increased, and when the count value is an even number, the vibration frequency is decreased.

  (4) A plurality of movies (one scene) recorded on the DVD are prepared, and the scenes displayed on the display body 152 are sequentially switched according to the count value. When reproducing an image, the sound corresponding to the image may be reproduced by combining the above-described first embodiment.

  (5) The above light emission, vibration, and image display (and sound reproduction) are appropriately combined according to the count value. Further, instead of changing the contents of the gimmick at every count, the contents of the gimmick may be changed every several counts, for example, every three counts.

  Thus, according to the present embodiment, in addition to the sound of the above embodiment, gimmick generation by light emission, vibration, and image display is performed, so that the performance is further improved.

Next, Embodiment 3 of the present invention will be described. In the present embodiment, the state of opening and closing of the lid 13 is captured using various sensors, and a gimmick is generated based on that. In this embodiment, in addition to the open / close sensor 202 of the above embodiment,
1) Speed (angular speed) sensor 204... Sensor that detects the opening and closing speed of the lid 13
2) Acceleration sensor 206... Sensor for detecting acceleration of opening / closing of the lid 13,
3) Angle sensor 208... Sensor for detecting the opening / closing angle of the lid 13
4) Illuminance sensor 210: a sensor for detecting the brightness outside the case,
Are provided. The detection results of these sensors are all supplied to the detection identification circuit 220.

  Next, the operation of the present embodiment will be described. In this embodiment, the state of opening and closing of the lid 13 is detected in more detail by various sensors included in the sensor group 200, and the gimmick is determined based on the detection results. appear.

Examples of detection by the sensor and generation of the gimmick include the following.
(1) The speed at which the lid 13 is opened is detected by the speed sensor 204, and the contents of the gimmick are changed corresponding to the detected speed. For example, when a recorded movie of sports such as the Olympics is recorded on the DVD, images of runners that run slowly and runners that run fast are prepared in the data list 112 as gimmick data. The image may be a live-action video or an animation. A speed threshold value for detecting whether the opening / closing speed of the lid 13 by the speed sensor 204 is slow or fast is set in advance and stored in the set value memory 222 of the detection identification circuit 220. When the detection identification circuit 220 identifies that the detection result of the speed sensor 204 is less than the speed threshold value, the gimmick data extraction circuit 110 extracts the gimmick data of the runner that runs slowly from the data list 112, which is the image signal generation circuit. 150. Then, the image of the runner who runs slowly is displayed on the display body 152. On the other hand, when the detection identification circuit 220 identifies that the detection result of the speed sensor 204 is equal to or greater than the speed threshold, the gimmick data extraction circuit 110 extracts the gimmick data of the runner that runs fast from the data list 112, which is the image. The signal is supplied to the signal generation circuit 150. Then, the image of the runner who runs fast is displayed on the display body 152.

  (2) When rakugo is recorded on the DVD, as the gimmick data, the slowly speaking voice and the quickly speaking voice are prepared in the data list 112, respectively. A speed threshold value for detecting whether the opening / closing speed of the lid 13 by the speed sensor 204 is slow or fast is set in advance and stored in the set value memory 222 of the detection identification circuit 220. When the detection identification circuit 220 determines that the detection result of the speed sensor 204 is less than the speed threshold, the gimmick data extraction circuit 110 extracts the gimmick data of the slowly speaking voice from the data list 112, which is the voice signal generation circuit. 120. Then, the sound of the rakugo that speaks slowly is output from the sound generator 122. Conversely, when the detection identification circuit 220 identifies that the detection result of the speed sensor 204 is equal to or greater than the speed threshold value, the gimmick data extraction circuit 110 extracts the gimmick data of the speech that is spoken early from the data list 112, which is the voice. The signal is supplied to the signal generation circuit 120. Then, the sound of the rakugo that speaks early is output from the sound generator 122. The audio data prepared in the data list 112 may be only data that speaks rakugo at a normal speed, and may be played back earlier or slower depending on the opening / closing speed of the lid 13. In addition, when it reproduces early, the voice becomes high as a result.

  (3) For example, when a horror movie is recorded on a DVD, if the lid 13 is opened at a normal speed, a part of the theme music of the movie will sound, and if the lid 13 is slowly opened, the stage of the movie It can be considered that a squeaking noise is generated as when opening the ruined door.

  The same applies to the acceleration sensor 206, the angle sensor 208, and the illuminance sensor 210. That is, different gimmick data is extracted from the data list 112 depending on whether or not the sensor detection result exceeds a threshold value stored in the set value memory 222, and is generated as sound, vibration, video, or the like.

  As described above, according to the present embodiment, since the detection operation is performed by the plurality of sensors for the opening and closing of the lid 13, various gimmicks according to the movement of the opening and closing of the lid 13 can be generated. A rich production effect can be realized.

  Next, a fourth embodiment of the present invention will be described. In this embodiment, the contents of the gimmick are changed according to the time, and a radio timepiece 226 is provided in the detection identification circuit 220. A mechanical clock can be considered as a means for measuring the time, but it is not preferable because the clock stays when the mainspring is fully extended. As for the electric timepiece, the time measurement stops when the main switch 108 is turned off, and the time measurement starts from the reset state even when the main switch 108 is turned on. Therefore, a radio timepiece 226 that can receive radio waves at the time of resetting, correct the time, and accurately measure time is employed.

  In the present embodiment, the radio clock 226 is referred to when the detection and identification by the detection and identification circuit 220 is repeated, and time information is also provided to the gimmick data extraction circuit 110. The gimmick data extraction circuit 110 extracts corresponding gimmick data from the data list 112 while referring to detection identification and time information based on the detection result of the sensor group 200, and a corresponding gimmick is generated.

Examples of detection by the sensor group 200 and occurrence of gimmicks include the following.
(1) For example, if a movie with a Christmas theme is recorded and a gimmick occurs when the lid 13 is opened / closed by the open / close sensor 202, the DVD is recorded from 6 am to 5 pm The main theme of a movie is played, the most romantic music in the movie is played from 5:00 pm to midnight, and the Christmas carol is played from midnight to 6:00 am.

  (2) In the case of a promotion DVD for a specific singer where different gimmicks occur corresponding to the opening / closing count value of the lid 13 by the opening / closing sensor 202, for example, the count value is set from 4 am to 10 pm In response to this, a part of the recorded songs is sequentially switched and reproduced, the singer's message is reproduced from 10 pm to midnight, and light is output from midnight to 4 am.

  Thus, according to the present embodiment, the contents of the gimmick can be changed according to the time. In addition, the contents of the gimmick may be changed according to the date and time, the tides and the moon. Alternatively, the time when the lid 13 is first opened may be stored in the set value memory 222 of the detection identification circuit 220, and the gimmick may be changed according to the elapsed time.

In addition, this invention is not limited to the Example mentioned above, A various change can be added in the range which does not deviate from the summary of this invention. For example, the following are also included.
(1) In the above-described embodiment, the main switch 108 may be a switch that cuts off the power supply circuit with an insulating piece and is turned on by pulling out the insulating piece. By using such a switch, it is possible to prevent unnecessary consumption of the battery by keeping the insulating piece inserted during storage before sale or display of products. When the seller pulls out the insulating piece at the time of purchase, or the purchaser pulls out the insulating piece after purchase, preparations for the occurrence of a “gimmick” are made. In addition, various switches and power supply circuits may be used.

  (2) As the sensor group, various sensors may be used as necessary as long as they detect an external action on the case. For example, various devices such as a reed switch that detects magnetism, an infrared sensor that detects infrared light, a pressure sensor that detects pressure, an optical sensor that detects light, and a gyro that detects rotation of the case may be used. In the case of a reed switch, for example, a magnet is provided on the lid side of the disk case, and the reed switch is turned on / off as the lid is opened and closed. In the case of an infrared switch, for example, an infrared sensor is provided outside the disc case, and when the disc case is held by hand, it is detected by the infrared sensor to generate a gimmick. In the case of a pressure switch, for example, when the disk case is pushed, the pressure switch is turned on to generate a gimmick.

  (3) A plurality of sensors may be used alone or in combination. A plurality of the same sensors may be provided. For example, two angle sensors and a timer are prepared. When the first angle sensor reaches the predetermined angle θ1, the first pulse is generated, and when the second angle sensor reaches the predetermined angle θ2, the lid reaches the predetermined angle θ2. The second pulse is generated. If the time interval between the first pulse and the second pulse is measured with a timer, the opening / closing speed of the lid can be detected based on the data.

  (4) In the above embodiment, the gimmick generated corresponding to the detected content is determined, but the content of the gimmick to be generated may be random. For example, a random number table is prepared and is used to generate a random number every time the lid is opened and closed. If gimmick data is extracted from the data list 112 according to the generated random number, a different gimmick can be generated each time the lid is opened and closed. You may make it perform some calculation with respect to the said random number. Furthermore, a plurality of gimmicks may be generated based on one sensor detection, or one gimmick may be generated based on a plurality of sensor detections. The content of the gimmick can be anything as long as it can be felt by the human senses.

  (5) The circuit configuration shown in the above embodiment may be changed in design so as to achieve the same effect. For example, in the above embodiment, the radio clock 226 is used for detection and identification. However, if the clock is considered to be a time sensor, the radio clock 226 can be included in the sensor group 200, and conditions for extracting gimmick data Therefore, it is possible to include the radio clock 226 in the gimmick data extraction circuit 110, and it is possible to include the radio clock 226 in the generation circuits 120 to 150 if it is considered to be a condition when the gimmick occurs. Of course, it may be executed in software using a microcomputer.

  (6) In the above embodiment, by turning off the main switch 108, the power supply to each part can be stopped and the generation of gimmicks can be stopped. After that, you may make it stop generating a gimmick.

  (7) In the above-described embodiment, a case where a so-called button battery is used as the power source has been described, but a solar battery or the like may be used.

  According to the present invention, by applying to a media case such as a CD or a DVD, it is possible to provide a media case with added value that is rich in expression and rich in taste.
