Description

  The present invention relates to a disc player that reproduces and outputs a disc of CD or DVD, and in particular, when a disc inserted into the disc player is not ejected for some reason even when an eject button is pressed, it is safely and reliably ejected. The present invention relates to a disc player with a disc forced ejection function.

  With respect to CD players that reproduce and output CD discs, CD players that record various types of audio data have become popular, and CD players that reproduce and output such various CDs have become popular. As for DVD players that reproduce and output DVD discs, DVD players that reproduce and output DVD discs that record video and audio in various recording formats are widely used. Also, disk players that play both CDs and DVDs have become widespread. Hereinafter, players that play and output various types of discs, such as these CD players and DVD players, are collectively referred to as “disc players”.

  The above-described disc player has been rapidly advanced by many technological developments to improve performance, and playback performance, operability and the like have been improved. However, even now, due to various causes, a disc inserted into a player is often not ejected even when a disc eject button provided in the player is pressed.

  That is, the disc player currently widely used, for example, as shown in FIG. 5 (a) shows the appearance of an in-vehicle disc player, with respect to the disc drive portion provided at the center of the machine body. Then, a disk is inserted as shown in the figure, and this is rotationally driven, and data at a predetermined position on the disk is read by a pickup and reproduced and output. In order to take out the disc, an eject button provided on the machine body is pressed, and after the disc stops rotating, the disc is pushed out and ejected.

  In this disk player, whether the disk is inserted or ejected is present in each position shown as the light emitting / receiving elements A to C in FIGS. 5B and 5C. A pair of light emitting elements and light receiving elements as shown in FIG. As a result, as shown in FIG. 5B, the signal of the light receiving element receiving the light from the light emitting element is detected, and when receiving the light, it is recognized that there is no disk between the light emitting element and the light receiving element. To do. On the other hand, as shown in FIG. 5C, when the disc is inserted between the light emitting element and the light receiving element, the light receiving element does not receive light from the light emitting element. Recognize that a disk exists.

  When detecting whether or not a disk exists between the light emitting element and the light receiving element as described above, for example, as shown in FIG. 6, there is a disk having a light transmission part depending on the type of the disk. To do. FIG. 1A shows an example of a cleaning disk as an example of such a disk, and shows a schematic view of the surface of the disk.

  Some of the discs have a transparent portion as shown in an enlarged view in FIG. When this disc is inserted into the disc player, when the light emitting / receiving element is located in this transparent part, the light receiving element receives the light of the light emitting element through the transparent part. Recognize that no disc is inserted.

  Therefore, for example, as shown in FIG. 6 (c), even if the presence of the disk is detected by the light emitting / receiving elements A and B, the presence of the disk is detected by the light emitting / receiving element C because the disk is almost ejected. The state is the same as the state of not detecting. That is, since the light emitting / receiving element C does not recognize the presence of the disc as described above even though the disc is inserted as shown in FIG. Erroneously detects that the disc is being ejected.

  Therefore, even if the eject button of the disc is pressed in the state as shown in FIG. 6D, it is determined that the disc player gives an eject instruction even though the disc is ejected, and the eject operation is performed. Not to do. Therefore, the user forcibly repeats an operation for instructing to remove the disk, for example, by pressing and holding the eject button for a while.

As described above, the state in which the disc is not ejected even when the eject button is pressed even though the disc is inserted into the player is shown as the main cause of the abnormality in FIG. 7 described later. ,
(A) Mechanism drive control unit becomes abnormal due to the influence of disturbance such as electrostatic noise (b) It becomes frozen due to a potential software failure (c) The disk is inserted by inserting a beam of light from the West, etc. into the mechanism Non-detection of insertion (d) There are various causes such as non-detection of the disk due to the transparent part of the disk such as sensor breakage and peeling of the disk coating.

  In addition, when the eject operation button is pressed for a long time and a carry-out operation different from the normal eject operation is performed, the transport motor is intermittently operated so that a disk or a foreign object is inserted into the insertion slot of the housing. Patent Document 1 discloses a technique in which a disk or a foreign object can be held and removed by hand before the disk or a foreign object falls from the insertion slot by slowly ejecting the disc and the foreign object from the insertion port. Further, in a slot loading type disk device, Patent Document 2 discloses a technique in which an initialization operation is performed once immediately after power-on to perform an initialization operation so that the disk device can be started smoothly.

  As described above, in the disc player, the disc is not ejected regardless of how many times the eject button is pressed while the disc is inserted due to various causes. FIG. 7 shows such a state as a main control unit in the disc player, which controls the entire player, and inserts the disc into the player under the instruction of the main control unit. A time chart of a mechanism drive control unit that controls various mechanisms that eject and rotate the disk is shown.

  In the conventional disc player shown in FIG. 7, an instruction to eject the disc to the main control unit when the user presses the eject button of the disc player is an instruction that the main control unit ejects the disc to the mechanism drive control unit. And the mechanism drive control unit attempts to eject the disk according to the instruction.

  However, as shown in the figure, due to various causes as described above, an abnormality has occurred in the disk player before the ejection instruction, and the control unit of the disk drive mechanism does not control the operation of the disk ejection. The state where it is not ejected occurs.

  At this time, the user notices that the disc player does not operate as it is in response to the eject instruction. For example, the user can depress the eject button for 3 seconds or 5 seconds or press the eject button many times. Many. The main control unit detects that the user is performing an operation requesting forcible ejection of the disc by such a signal from the eject button, and instructs the mechanism drive control unit to perform the disc ejection operation. However, in the mechanism drive control unit, the disk drive mechanism does not operate and the disk is not ejected due to the occurrence of the abnormality.

  Therefore, although the user turns off the main power switch and tries to redo everything, many disc players remember various operating states immediately before turning off the power by the resume function even after the main power switch is turned off. Even if is inserted, all the operations are restored and recovered, so the state where the disc is not ejected continues.

  As a subsequent measure, initialization may be performed by pressing a reset button, which is provided in many disc players, which is operated at a special time, with a tool or the like. However, when such initialization is performed, all the player operation modes set by the user and data dedicated to the user are all deleted, and such setting must be performed again. You can't do it often.

  That is, since the conventional disc player is composed of functional blocks as shown in FIG. 8, for example, the above-described problem occurs. That is, in the conventional disc player shown in FIG. 8, the main control unit 51 that controls the entire disc player, and the audio and image data recorded on the disc 81 in accordance with instructions from the main control unit 51 are processed and output. In this example, an audio image control unit 61 that performs various operations driven by various motors and a mechanism drive control unit 71 that controls operation according to instructions from the main control unit 51 are shown.

  The audio image control unit 61 performs desired processing on the audio data and image data read by the pickup 84 from the disk 81 rotated by the disk rotation motor 83, and outputs the audio from the amplifier 67 to the speaker 68 for monitoring. 69 outputs an image. Therefore, the audio image control unit 61 includes a pickup operation control unit 62 that controls the pickup 84 that reads desired data from the rotating disk 81.

  The audio image control unit 61 further includes an RF signal capturing unit 63 for capturing an RF signal from the disc, a data reproducing unit 64 for reproducing audio data and image data from the captured RF signal, and audio data and image data. In this example, a waveform shaping unit 65 that performs desired waveform shaping and the like, and an image processing unit 66 that performs image processing for output to a monitor 69 are illustrated.

  On the other hand, the mechanism drive control unit 71 is provided with a disk insertion / ejection drive control unit 72 for performing control for inserting and ejecting a disk, and the disk insertion control unit 73 therein includes a disk rotation motor 83 that receives a disk inserted from the disk insertion port. The operation of mounting on the rotating table 82 that rotates is performed. In addition, a disc eject control unit 74 is provided which operates by detecting that the user has pressed the eject button 89 of the disc mainly on the inserted disc.

  In these controls, signals from the light emitting / receiving elements composed of the light emitting element 86 and the light receiving element 85 are taken in, and the inserted state and ejected state of the disc are detected as shown in FIG. The mechanism drive control unit 71 includes a disk rotation control unit 75 that controls the drive of a disk rotation motor 83 that rotates the disk 81.

  In the mechanism drive control instruction unit 55 of the main control unit 51 shown in FIG. 8, an operation instruction is given to the mechanism drive control unit 71 as described above. And the signal of the light receiving element 85 are detected, and the operation of the disk discharge motor 88 that drives the disk discharge lever 87 is detected. Thereby, the disc insertion detection unit 56 detects the insertion of the disc, and the disc ejection detection unit 57 detects the ejection of the disc.

  The eject button press detection unit 59 detects a user's eject instruction to the eject button 89 provided in the machine body, and the disc eject instruction unit 58 uses a disc ejection control unit in the disc insertion / ejection drive control unit 72 of the mechanism drive control unit 71. 84 is instructed to eject the disc.

  In the conventional disc player, the mechanism drive control instructing unit 55 that operates under the control of the disc player integrated control unit 52 when the user presses the disc eject button 89 is configured by the functional block as described above. Normally, the disc eject instruction unit 58 instructs the mechanism drive control unit 71 to eject the disc as described above to perform a desired operation.

  On the other hand, if the disc is not ejected even if the eject button is pressed due to the above various causes, the disc player integrated control unit 52 will give the instruction and repeat the operation no matter how much the eject button is pressed thereafter. The disc cannot be ejected. When the reset button of the disc player is pressed, all data of the disc player is initialized by the data reset unit 53 in the overall control unit for resetting various data of the disc player overall control unit as described above. There is a problem.

  Therefore, according to the present invention, when a disk drive mechanism malfunctions due to various causes during the operation of the disk player and the disk is not ejected even if the user presses the eject button, The main object is to provide a disc player with a disc forced ejection function that can perform ejection.

  In order to solve the above problems, a disk player with a forced disk ejection function according to the present invention has a drive mechanism control including an ejection control means for controlling the disk ejection operation of the disk player and a data reset means for resetting internal data. And a main control means for performing overall control of the disc player and outputting an operation instruction to at least the drive mechanism control means. In the main control means, the user performs a predetermined operation on the eject button of the disc. When it is detected that the operation has been performed, a data reset instruction for resetting the internal data is output to the mechanism drive control means.

  According to another aspect of the present invention, there is provided a disk player with a forced disk ejection function, wherein the user performs a predetermined operation on the disk ejection button continuously by pressing the ejection button a predetermined number of times. It is the operation to perform.

  According to another aspect of the present invention, there is provided a disk player with a forced disk ejection function in which the user performs a predetermined operation on a disk ejection button a predetermined number of times within a predetermined time. It is a pressing operation.

FIG. 11 is a functional block diagram mainly showing portions related to the problem of the present invention in a conventional disc player.

  Embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a functional block diagram of the present invention, and shows a functional block diagram in which the present invention can be implemented in various modes. Therefore, in the present invention, any one of these functional units can be selected and implemented in various modes. In addition, in the same figure, the function part which performs each function can be said to be a means which performs each function.

  The functional block diagram in FIG. 1 is shown in association with the functional block diagram of the conventional example shown in FIG. 8. In particular, the conventional block is different from the conventional example in the composition drive control instructing unit 5 in the main control unit 1. The control part 8 is provided and the instruction | indication signal is output with respect to the mechanism drive control part 31 from the mechanism drive control part reset instruction | indication part 15 and the mechanism drive control part forced ejection action | operation instruction | indication part 16 with the various operation | movement mentioned later. Further, the mechanism drive control unit 31 is different in that it includes a disk forced ejection drive unit 35 in the disk ejection control unit 34 and a data reset unit 37 in the mechanism drive control unit in order to respond to the instruction. An example of a block diagram is shown.

  Therefore, the other parts are the same as the functional block diagram of the conventional example shown in FIG. 8, and the main control unit 1 for controlling the entire disc player and the audio recorded on the disc 41 according to the instructions of the main control unit 1 An audio image control unit 21 that processes and outputs image data and a mechanism drive control unit 31 that controls various mechanisms driven by various motors according to instructions from the main control unit 1 are mainly provided.

  The main control unit 1 includes a disc player comprehensive control unit 2 that comprehensively controls the entire disc player, and an audio image control instruction unit 4 that gives an operation instruction to the audio image control unit 21 from the disc player comprehensive control unit 2. And a mechanism drive control instruction unit 5 that instructs the mechanism drive control unit 31 from the disc player integrated control unit 2 in the same manner.

  The audio image control unit 21 performs desired processing on the audio data and image data read by the pickup 44 from the disk 41 rotated by the disk rotation motor 43, outputs audio from the amplifier 27 to the speaker 28, and monitors 29 The image is output to. Therefore, the audio image control unit 21 includes a pickup operation control unit 22 that controls the pickup 44 that reads desired data from the rotating disk 41.

  The audio image control unit 21 includes an RF signal capturing unit 23 that captures an RF signal from a disc, a data reproduction unit 24 that reproduces audio data and image data from the captured RF signal, and audio data and image data. 8 is provided with a waveform shaping unit 25 that performs desired waveform shaping and the like, and an image processing unit 26 that performs image processing for output to the monitor 29.

  On the other hand, the mechanism drive control unit 31 is provided with a disc insertion / ejection drive control unit 32 for performing control for inserting and ejecting a disc, and the disc insertion control unit 33 therein includes a disc rotation motor for discs inserted from the disc insertion port. A disc insertion control unit 33 for placing on the rotary table 42 that rotates at 43, and a disc ejection control unit 34 that operates by detecting that the user has pressed the eject button 49 mainly on the inserted disc. I have.

  The disk ejection control unit 34 includes a disk that is given priority over all current operations in accordance with an instruction from a mechanism drive control unit forcible ejection operation instruction unit 16 in a mechanism drive control instruction unit 5 of the main control unit 1 described later. The disk forced ejection drive unit 35 for performing the ejection operation is provided.

  Further, the mechanism drive control unit 31 includes a disk rotation control unit 36 for performing drive control of a disk rotation motor 43 that rotates the disk 41. Further, a mechanism drive control unit internal data reset unit 37 is provided, the CPU that controls various operations in the mechanism drive control unit 31 is initialized, and all stored data for performing various operations is reset. The data to be reset at this time is very different from the data to be reset by the data reset unit 3 in the general control unit provided in the disc player general control unit 2 as will be described later of the main control unit 1, and is simply for driving the mechanism. It only resets the data that is needed. In addition, since the CPU that performs the operation control in the mechanism drive control unit 31 is initialized here, it can be solved even when the operation is frozen due to a software problem.

  On the other hand, the main control unit 1 includes the disc player integrated control unit 2 as described above, and performs overall control of the entire disc player by predetermined software. Is provided with a data reset unit 3 in the overall control unit, which resets and initializes various data set by the user of the disc player when using the disc player.

  Note that when data is reset by the internal control unit data reset unit 3, it takes a lot of work to restore the original state thereafter. Therefore, in the present invention, when this is difficult to eject a disk, which is often caused by a disk player, this part is used. Without resetting, only the data necessary for mechanism drive control is reset by the in-mechanism drive control unit data reset unit 37 of the mechanism drive control unit 31 as described above.

  In the mechanism drive control instruction unit 5 of the main control unit 1 shown in FIG. 1, an operation instruction is given to the mechanism drive control unit 31 as described above. In the present invention, the disk forced ejection control unit 8 is particularly provided. And an eject button pressing detection unit 6 that detects that the user has operated the eject button 49 and a signal of the disc ejection detection unit 7 that detects the operation of the disc ejection motor 48 that drives the disc ejection rubber roller 47. It is out.

  The disc forced eject control unit 8 includes an overtime measuring unit 9 after the first press of the eject button, and measures an elapsed time since the user first pressed the eject button 49. Whether or not it is the first time the user presses the eject button at this time is determined when a certain time such as 2 seconds elapses after the eject button is pressed and then the eject button is pressed thereafter. This is the first press. Therefore, the measurement by the elapsed time measuring unit 9 after the first press of the eject button is reset when the predetermined time elapse detection unit 10 detects that a predetermined time has elapsed after the first press of the eject button, which will be described later.

  The predetermined time elapsed detection unit 10 after the first press of the eject button detects whether or not the elapsed time measured by the elapsed time measurement unit 9 after the first press of the eject button first has elapsed, for example, 2 seconds set by the predetermined time setting unit 11 To do. Data indicating whether the detection result has passed or not is output to a press detection unit 13 for a predetermined number of times within a predetermined time of an eject button described later.

  The eject button press count counting unit 12 counts the number of times the user has pressed the eject button 49, and this count is also within a time period in which a predetermined time elapses after the first press of the eject button is detected. Therefore, when the predetermined time has elapsed, the measurement result of the number is reset.

  When the predetermined number of times the eject button has been pressed within a predetermined time, the detection unit 13 determines that the predetermined time has not yet elapsed after the initial pressing of the eject button for the first time. It is detected whether or not the number of times the eject button has been pressed has reached a predetermined number of times set by the eject button pressing predetermined number setting unit 14, for example, three times.

  When the detection unit 13 detects that the user presses the eject button a predetermined number of times within a predetermined time, for example, when the user detects that the user has pressed the eject button a predetermined number of times such as 3 times within a predetermined time such as 2 seconds, as described above. When it is detected that the person has repeatedly hit a predetermined number of times at a predetermined speed, the signal is output to the mechanism drive control unit reset instruction unit 15 and the mechanism drive control unit forced ejection operation instruction unit 16.

  In the mechanism drive control unit reset instruction unit 15, the mechanism drive control unit 31 is instructed to reset the data stored in the mechanism drive control unit 31, and thereby, the data in the mechanism drive control unit of the mechanism drive control unit 31. The data stored in the mechanism drive control unit 31 is reset by the reset unit 37. The data stored in the mechanism drive control unit 31 is only data necessary for driving the mechanism, and as described above, the various data in the disc player integrated control unit 2 of the main control unit 1 In contrast, erasing it does not have a significant effect on the user or on the operation of the player.

  The mechanism drive control unit forcible ejection operation instructing unit 16 instructs the mechanism drive control unit 31 to perform an operation for forcibly ejecting the disk after processing corresponding to the mechanism drive control unit reset instruction unit 15 is performed. Is output. As a result, the mechanism drive control unit 31 drives the disk ejection motor 48 with priority over other processes in the disk forced ejection drive unit 35 in the disk ejection control unit 34 of the disk insertion / ejection drive control unit 32, and the disk ejection rubber. The roller 47 is rotated to forcibly eject the inserted disc.

  In the present invention composed of the functional blocks as described above, the present invention can be implemented by sequentially operating according to the operation flow shown in FIG. That is, in the example of the disc eject process for ejecting the disc from the disc player shown in FIG. 2, the determination is made based on whether or not the eject button is initially pressed (step S1). Here, when it is determined that the user has not yet pressed the eject button, this operation is repeated to wait.

  When it is determined in step S1 that the user has pressed the eject button, the number of eject button presses is counted (step S2), and the number is set once (step S3). Next, the process proceeds to step S4, where it is determined whether or not a predetermined time such as 2 seconds has elapsed after the timer count is started. If it is determined that the predetermined time has not yet elapsed, the process proceeds to step S5 to determine whether or not the eject button has been pressed.

  When it is determined in step S5 that the eject button has not been pressed, the process returns to step S4 again to determine whether or not a predetermined time has elapsed after the timer count has started. Do not perform forced disk removal processing.

  When it is determined in step S5 that the eject button has been pressed, or when it is determined that the eject button has been pressed by returning to step S4 again as described above and proceeding to step S5 when the predetermined time has not yet elapsed. In step S6, the eject depression count is incremented by one. Therefore, when coming to step S9 in order from step S1 as described above, the eject button pressing frequency count is two.

  Thereafter, in step S7, it is determined whether or not the number of ejection has reached a predetermined number such as three. Here, it is determined that the predetermined number of times has not been reached if it has been two times as described above, and the process returns to step S4 to check whether or not a predetermined time has elapsed after the timer count is started. Here, when it is determined that the predetermined time has not yet elapsed, it is determined whether or not the eject button has been pressed in step S5 as described above. On the other hand, as described above, when it is determined in step S4 that the predetermined time has elapsed during the subsequent processing, the forced disk exclusion processing of the present invention is not performed.

  Returning to step S4 as described above, when it is determined that the predetermined time has not yet elapsed, it is determined in step S5 that the eject button has been pressed, and in step S6, the eject button press count is incremented by one. Here, when the series of processes is performed, the eject button is pressed three times.

  Therefore, when proceeding to step S7 thereafter, if the predetermined number of times is three as described above, it is determined that the number of ejections has reached the predetermined number, and the process proceeds to step S8, where the main control unit of the disc player An instruction to initialize and reset the CPU is output to the mechanism drive control unit. With this reset instruction, the CPU of the mechanism drive control unit is initialized. Thereby, even if the software of the mechanism drive control unit is in a frozen state, the software operates normally.

  Thereafter, in step S9, the disc player main control unit outputs an instruction to perform a forced ejection operation to the mechanism drive control unit. As a result, as shown in step S10, the mechanism drive control unit resets the internal storage data and performs the operation of forcibly ejecting the disk. Thereafter, the disc eject process of the present invention returns to step S1 to determine whether or not the eject button has been pressed again.

  As a result of the above processing, when a predetermined number of times such as three times including the first eject button is reached within a predetermined time such as 2 seconds after the first eject button is pressed, that is, three times within two seconds When there is repeated hitting, the data in the mechanism drive control unit is reset and the disk is forcibly ejected. By this operation, the predetermined time can be set to 3 seconds, the predetermined number of times can be set to 4 times, and the like can be arbitrarily set and executed.

  FIG. 3 shows the operation of the eject button as described above. That is, FIG. 3 shows a state where the key as the eject button is pressed three times from the OFF state. Here, when the key is turned on for the first time after the key is turned off in the first normal state, the timer starts counting. In the normal case, the ejection operation is performed when the key is turned on for the first time.

  After that, the key is repeatedly turned on and off as described above, and in the example shown in the figure, when the key is turned off by performing the third key ON operation, the forced time has not elapsed since 2 seconds of the predetermined time has elapsed. Eject is activated. In addition to the above example, if it is within 2 seconds of the predetermined time at the moment when the key is turned on for the third time, a forced ejection may be activated.

  In addition, as described above, when the eject button is repeatedly hit within a predetermined time, the disc is forcibly ejected, and the timer and the eject button press count are reset. If not, when the predetermined time has elapsed, the timer is cleared by timeout as described in the operation flow.

  FIG. 4 is a time chart similar to FIG. 7 showing the above-described conventional example for the present invention as described above. In the same figure as FIG. 7, the main control unit and the mechanism drive control unit are provided. When the main control unit detects that the eject button has been pressed and makes an eject request to the mechanism drive control unit, The disk drive mechanism does not operate due to the occurrence of an abnormality, and the disk is not ejected in the same manner as in FIG.

  In the present invention, after that, when the user repeatedly hits the eject button a predetermined number of times within a predetermined time, the main control unit first instructs the mechanism drive control unit to reset the mechanism drive control unit, As a result, the drive mechanism of the disc player returns from the abnormal state to the normal state. Secondly, by making a forced ejection request, the mechanism drive control unit that has returned to the normal state automatically performs the disk ejection operation.

  By performing the operation as described above, the present invention eliminates the need for resetting the data of the main control unit when the disk is no longer ejected as in the prior art, and does not cause a big problem for the user. It is possible to return to normal by simply resetting. Thus, when the user subsequently depresses the eject button, the disc drive operation can be surely performed by the mechanism drive control unit that has returned to normal as described above.

  Further, after the normal recovery as described above, the disk can be automatically forcibly removed, and the disk can be ejected without waiting for the user's subsequent operation. At this time, the forced ejection is performed by detecting the continuous hitting of the eject button performed by the normal user when the disk is not ejected. Therefore, the forced ejection of the disk can be easily performed by a natural operation.

  The operation of the eject button performed by the user at this time is not limited to detecting that the eject button is pressed a predetermined number of times within a predetermined time as described above, for example, when the eject button is continuously pressed a predetermined number of times or more. Can be implemented in various ways, such as forcing a disk to be detected.
