Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a disk reproducing apparatus for reproducing a disk such as a CD and a DVD, and more particularly to a disk reproducing apparatus having a function of preventing a disk loaded in a main body from being illegally ejected.

[0002]

[Prior art]

 2. Description of the Related Art Conventionally, retailers of discs such as CDs and DVDs have prepared playback devices for listening as one of customer services. The customer listens to the disk using the playback device for trial listening and purchases the favorite disk. In order to promote the sales of the playback devices, the retailers of the playback devices play back the discs with the playback devices arranged in the store to appeal to the customers the performance of the playback devices.

By the way, a general reproducing apparatus has a configuration in which a loaded disc can be easily ejected (taken out) in consideration of operability in disc replacement or the like. Specifically, the disc loaded on the main body is ejected by operating an eject switch provided on the main body. Therefore, the disc loaded on the main body may be operated by the customer without permission to operate the eject switch to damage the ejected disc. There was also a problem of disk theft.

In order to solve this problem, there has been proposed a reproducing apparatus having a function of setting whether to prohibit ejection of a disc loaded in a main body (Japanese Patent Laid-Open No. 7-37320).

[0005]

[Problems to be solved by the invention]

 However, the above device must release the prohibition of the ejection of the disk when exchanging the disk with the main unit, and after exchanging the disk, set the prohibition of the ejection of the disk again. A clerk sometimes forgot to set the eject prohibition of a disk after this disk replacement. Therefore, it could not be said that it was sufficient to prevent the above-mentioned damage and theft of the disk.

The purpose of this invention is not to provide a function to prohibit the ejection of a disc, but to complicate the ejecting operation of the disc, thereby almost surely preventing damage or theft of the disc loaded in the main body. An object of the present invention is to provide a disk reproducing apparatus.

[0007]

[Means for Solving the Problems]

 The disk reproducing apparatus of the present invention has the following configuration in order to solve the above problem.

(1) Loading means for setting a disk at a predetermined position on the main body, ejecting means for discharging the disk set at the predetermined position by the loading means to the outside of the main body, and the predetermined position by the loading means When a specific key provided on the main body of the apparatus is operated, the specific key is turned on when a specific key provided on the apparatus main body is operated. A control unit that executes a first process if the operation is continued for less than a predetermined time; and executes a second process if the operation is continued for a predetermined time or more. The second process executes the ejecting unit. This is the processing to be performed.

In this configuration, when a specific key provided on the apparatus main body is continuously operated for a predetermined time or more, the disc loaded on the main body is ejected. However, if the time during which the specific key is continuously operated is shorter than the predetermined time, another process is executed.

Here, if the predetermined time is set to several seconds, for example, 5 seconds, a person who does not know that the disc is not ejected unless a specific key is continuously operated for 5 seconds or more is pressed for about 1 second. Even if you do it, you do not keep it for more than 5 seconds. If the time during which a specific key is continuously operated is shorter than the predetermined time, another process other than the ejection process is executed. Therefore, the specific key is recognized as a key to be operated when executing this another process, and a person who does not know the ejecting method of the disc does not continue to operate for more than 5 seconds. Therefore, it is possible to almost certainly prevent the disc loaded on the main body from being ejected without permission.

[0011] The specific key may be, for example, a key operated when stopping the reproduction, a key operated when starting the reproduction, or a key other than this. It may be.

In addition, since there is no need for a dedicated key to be operated when the disc is ejected to the main body, the number of operation keys in the main body can be reduced, and the effect of reducing the cost of the main body can be obtained.

(2) There is provided receiving means for receiving a control signal transmitted from the remote control device, wherein the control means executes a process based on the control signal received by the receiving means, and A key for transmitting a control signal for causing the means to execute the second process is provided independently.

In this configuration, since the remote control device is provided with a dedicated key to be operated when ejecting a disk, the use of the remote control device can prevent the operability in disc replacement or the like from being lowered.

[0015] (3) There is provided a receiving means for receiving a control signal transmitted from the remote control device, wherein the control means is a means for executing a process based on the control signal received by the receiving means, and When the specific key is continuously operated for a predetermined time or more before a predetermined time elapses after receiving the transmitted specific control signal, the ejecting means is executed.

With this configuration, when the remote control device is operated to cause the main body to receive a specific control signal, and thereafter the specific key is continuously operated for a predetermined time or more, the disc loaded in the main body is ejected. Is done. Therefore, the disc loaded on the main body can be more reliably prevented from being ejected without permission.

[0017]

[Embodiment of the invention]

 Hereinafter, a disc reproducing apparatus according to an embodiment of the present invention will be described.

FIG. 1 is a diagram showing a configuration of a disk reproducing apparatus according to this embodiment, and FIG. 2 is a front view of the disk reproducing apparatus. The disc reproducing apparatus 1 includes a control section 2 for controlling the operation of the main body, an operation section 3 for performing an input operation on the main body, a reproducing section 4 for reproducing a disc loaded on the main body, and a remote control device 10. A receiving unit 5 for receiving the transmitted control signal and an output unit 6 for outputting a video based on the video signal reproduced by the reproducing unit 4 and an audio based on the audio signal are provided.

The disc reproducing apparatus according to the embodiment is a reproducing apparatus for reproducing a DVD, and is a so-called DVD combo having a display device at the output unit 6. On the front of the main unit, as shown in FIG. 2, a stop key 21 for stopping the disk playback operation in the playback unit 4 as the operation unit 3, a playback key 22 for starting the playback operation, and a winding for returning the playback position of the disk. A return key 23 and a fast-forward key 24 for fast-forwarding the playback position of the disc are provided, but an eject key operated when ejecting the disc is not provided.

The remote control device 10 is provided with a dedicated key for transmitting a control signal for instructing the ejection of the disc to the disc device 1 main body.

The disc is placed on a tray 11 shown in FIG. The tray 11 is configured to be movable in the direction indicated by the arrow in FIG. FIG. 2 shows a state where the tray 11 protrudes from the main body. In this state, the disk is loaded on the tray 11 and the tray 11 is stored (pushed) into the main body, whereby the disk is loaded. In addition, when the disc is ejected, the tray 11 is pushed out of the main body to be in the state shown in FIG. The tray 11 is configured to be movable in a direction indicated by an arrow in FIG. 2 by a motor (not shown).

Next, the operation of the disk reproducing apparatus 1 according to this embodiment will be described.

FIG. 3 is a flowchart showing the operation of the disk reproducing apparatus according to this embodiment. The disc reproducing apparatus 1 determines whether or not an input operation has been performed on the operation unit 3 or whether or not a control signal has been received from the remote control device 10 in the receiving unit 5 (s1, s2).

When the receiving section 5 receives the control signal from the remote control device 10, the disc reproducing apparatus 1 executes a process according to the received control signal (s 3). For example, if the received control signal is a control signal for instructing the start of reproduction, the reproduction section 4 starts reproduction of the disk loaded on the main body. If the control signal is an instruction to stop the reproduction, the reproduction of the disc in the reproduction unit 4 is stopped. Further, if it is a control signal for instructing the ejection of the disc, the tray 11 is made to protrude from the main body.

The remote control device 10 is managed in a store, and is not used by a customer who listens to a disk for trial listening. The customer who listens to the disk operates keys provided on the operation unit 3.

When a key of the operation unit 3 is operated, the disk reproducing device 1 determines whether the operated key is the stop key 21 (s4). If it is determined that the key is not the stop key 21, a process corresponding to the operated key is executed (s5). For example, when the reproduction key 22 is operated, the disk reproducing apparatus 1 starts reproducing the disk loaded on the main body in the reproducing section 4.

When determining that the stop key 21 has been operated, the disc reproducing device 1 determines whether the stop key 21 has been operated for 5 seconds or more (s6). Here, if it is determined that the operation has not been continued for 5 seconds or more, a stop process for stopping the playback process of the disc in the playback unit 4 is executed (s8). In addition, when the disc reproducing device 1 determines that the stop key 21 has been continuously operated for 5 seconds or more, the disc reproducing device 1 executes an eject process for causing the tray 11 to protrude from the main body (s7).

As described above, the disc reproducing apparatus 1 of this embodiment can eject a disc by continuously operating the stop key 21 provided on the main body for 5 seconds or more. For this reason, a person who does not know that the disc will not be ejected unless the stop key 21 is continuously operated for more than 5 seconds, that is, a customer who listens to the disc, does not keep operating the stop key 21 for more than 5 seconds. . Therefore, the disc loaded on the main body is not ejected without permission, and it is possible to reliably prevent the disc from being damaged or stolen.

In this embodiment, the ejecting of the disk is not prohibited as in the conventional device, but the operation at the time of the ejection is only complicated. There are no problems such as disk corruption or theft.

Further, as described above, the remote controller 10 is provided with a dedicated key (eject key) for transmitting a control signal for instructing the main body to eject, so that when the clerk changes the disk, Since the remote control device 10 may be used, the operability does not decrease.

Further, since the eject key is not provided in the main body of the disc reproducing apparatus 1, an effect of reducing the cost of the main body can be obtained.

In the above-described embodiment, the disc is ejected when the stop key 21 is continuously operated for 5 seconds or more. For example, the disc is ejected when the playback key is continuously operated for 5 seconds or more. The disk may be ejected when another key is continuously operated for 5 seconds or more.

Next, another embodiment of the present invention will be described. The disk reproducing apparatus 1 of this embodiment also has the configuration shown in FIG.

In the disk reproducing apparatus 1 of this embodiment, the remote controller 10 is not provided with an eject key.

FIG. 4 is a flowchart showing the operation of the disk reproducing apparatus 1 of this embodiment. The disc reproducing apparatus 1 determines whether an input operation is performed on the operation unit 3 or whether a control signal is received from the remote control device 10 in the receiving unit 5 (s11, s12). When a key provided on the operation unit 3 is operated, the disk reproducing device 1 executes a process corresponding to the operated key (s13). For example, when the reproduction key 22 is operated, the reproduction section 4 starts reproducing the disc loaded on the main body. When the stop key 21 is operated, the playback process of the disc in the playback unit 4 is stopped.

When receiving a control signal from the remote control device 10 in the receiving unit 5, a process corresponding to the received control signal is executed (s 14), and the received control signal is a control signal for instructing stop of reproduction. It is determined whether or not (s15). If the received control signal is not a control signal for instructing stop of reproduction, the disc reproducing device 1 returns to s11 and repeats the above processing.

On the other hand, if the received control signal is a reproduction stop signal, the process returns to s11 after waiting five seconds (s16).

When the stop key 21 is operated while waiting in s16 and the operation of the stop key is continued for 5 seconds or more (s17, s18), the disc reproducing apparatus 1 executes the ejection process (s17). s19).

As described above, in the disk reproducing apparatus 1 of this embodiment, the stop key of the main body is operated within 5 seconds after the receiving section 5 receives the control signal for instructing the reproduction to be stopped from the remote control apparatus 10. When the operation of the stop key continues for 5 seconds or more, the disc loaded in the main body is ejected. Therefore, the remote controller 10 is required to eject the disc loaded on the main body.

For this reason, unless the remote control device 10 is managed in a store and used by a customer who listens to the disc, the disc loaded on the main unit is not ejected without permission, and the disc is damaged or stolen. Can be reliably prevented.

It should be noted that the disc reproducing apparatus 1 of this embodiment does not prohibit the ejection of a disc as in the conventional apparatus, but merely complicates the operation at the time of ejection. There is no problem such as disk damage or theft caused by forgetting to set eject prohibition.

In the above description, when the receiving unit 5 receives the control signal instructing the stop of the reproduction, the process after s16 is executed. However, when the control unit receives another type of control signal, the process after s16 is performed. May be executed.

Further, in the above embodiment, the disc reproducing apparatus 1 is an apparatus for reproducing a DVD, but may be an apparatus for reproducing another type of disc such as a CD.
