According to another aspect of the present invention, in such a disk drive device, the light source control unit turns on the light source before the disk is inserted into the disk insertion / ejection opening, so that the disk is inserted / ejected. After being inserted into the exit, the light source is turned off at a predetermined timing.

In another aspect of the invention, in addition to the disk drive device of each of the above-mentioned inventions, the light source control unit ejects the disk held by the disk drive mechanism, and a part of the disk is ejected from the disk insertion / ejection opening. After the light source is turned on by being protruded to the outside, the light source is turned off after a predetermined period of time.

Preferably, the predetermined period of time is set based on the time when the disc is ejected from the disc insertion / ejection port to the outside and the disc is taken out. .

In another aspect of the present invention, in addition to the disk drive device of the above-mentioned inventions, the light source faces the surface of the light transmitting layer of the disk when the disk protrudes outside from the disk insertion / ejection opening.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the present invention will be described. In the embodiment described here, a CD player that plays a CD as a disk drive will be described.

In FIG. 1, case 2 of the CD player 1
Is provided with a disk insertion / ejection port 4 for performing insertion / removal operation of a disk D3, and a disk drive mechanism 5 for rotating and driving the disk and an optical pickup unit 6 for reading information written on the CD3. Are provided.
Further, inside the case 2, a light source 7 such as a light emitting diode and a light source control unit 8 for controlling turning on / off of the light source 7 are provided at positions where the CD 3 can be irradiated with light (this will be described later). Is provided.

In this embodiment, the light source control unit 8 inserts the CD 3 from the disk insertion / ejection port 4 and holds the CD 3 in the disk drive mechanism 5. Thereafter, the CD 3 is ejected, and a part of the CD 3 is removed. The light source 7 is turned on / off based on the position of the disk during a series of operations leading to a state where the disk is projected from the disk insertion / ejection port 4 to the outside.

More specifically, the CD 3 is mounted on the disk drive mechanism 5.
When a detection signal (referred to as a holding state detection signal s1) obtained by detecting that the state has been held is received,
A detection signal (discharge state) obtained by detecting that the CD 3 held in the disk drive mechanism 5 is ejected and a part of the CD 3 is projected outside from the disc insertion / ejection port 4 On / off control of the light source 7 is performed in response to the detection signal s2). The light source control unit 8
Has a timer 9 and, for example, controls to automatically turn off the light source 7 after a predetermined period of time after the light source 7 is turned on after the CD 3 is ejected.

By the way, as shown in FIG. 2, the CD 3 is a thin disk-shaped light transmitting layer 31 made of a transparent plastic (polycarbonate), the irregularities formed on the light transmitting layer 31 and the irregularities. An information recording layer 32 on which information is recorded, which is composed of a light-reflecting metal film portion adhered to the unevenness by vapor deposition or the like, a hard resin for protecting the information recording layer 32 and affixing a label indicating a product, etc. The protective surface 33 is composed of:

When such a CD 3 is set in the CD player 1 shown in FIG. 1, the CD 3 is inserted into the disc insertion / ejection slot 4 in the direction indicated by the arrow x in FIG. And when CD3 is inserted to a certain position,
A member (not shown) on which the CD 3 is placed is lowered and held by the disk drive mechanism 5 in a state shown by a broken line in FIG.

When the operation is started in a state held by the disk drive mechanism 5, the CD 3 starts rotating and the optical pickup section 6 also starts to drive, so that the information recorded on the information recording layer 32 of the CD 3 is read. And played. Illustration of components that are not directly related to the gist of the present invention, such as a reproduction processing unit that performs a process of reading and reproducing this information, is omitted.

Hereinafter, the lower surface of the CD 3, that is, the surface of the light transmitting layer 31 facing the optical pickup section 6 is referred to as an information recording side surface 3a. The CD 3 existing in the disc insertion / ejection port 4 in FIG. 1 is ejected from the CD 3 held by the disc drive mechanism 5 and a part of the CD 3 projects outside from the disc insertion / ejection port 4. In the following, such a state is referred to as a discharge state, and the discharge state is indicated by a symbol A in FIG.

The light source 7 emits light to the information recording side surface 3a of the CD 3 in a position close to the disk insertion / ejection port 4 in the case 2 and in the ejection state (the state indicated by A in FIG. 1). Is provided so as to be able to irradiate. In the example of this embodiment, since the CD 3 is inserted into the CD player 1 with the information recording side surface 3a facing down, the light source 7 is mounted so as to emit the light upward. Further, the light source 7 is provided so that its optical axis 7a is orthogonal to the information recording side surface 3a of the CD.

The light source 7 is in a non-lighting state when the CD 3 is held in a state where it can be reproduced by the disk drive mechanism 5 (a state shown by a broken line in FIG. 1).
Is turned on when the is in the discharge state (the state shown by A in FIG. 1).

To put the CD 3 in the ejected state (the state shown by A in FIG. 1), the user may press the eject button (not shown) or the like. The discharging operation may be automatically performed when the processing is completed.

The color of the light emitted from the light source 7 may be colorless, but may be a specific color. When we actually experimented in a dark place, we found that orange and green colors did not give any visual discomfort, were excellent in design, and were excellent in informing the user. It turned out to be obtained. The light source 7 is not limited to a light emitting diode, but may be a light emitting element using an ordinary bead ball or EL.

Also, even before the CD 3 is inserted into the disc insertion / ejection slot 4, when the CD player 1 is in an operable state (power switch is on),
The light source 7 is turned on, and the light source 7 is turned off when the CD 3 is held in the disk drive mechanism 5 in a reproducible state.

After the CD 3 is in the discharging state as shown in FIG. 1A and the light source 7 is turned on, the light source 7 is turned off automatically after a predetermined time predetermined by the timer 9 as described above. Turn off the light. For a certain period of time until the light is turned off, considering the possibility that a plurality of CDs are successively reproduced one after another, such as pulling out the CD and inserting the next CD after the reproduction of one CD is completed. It is desirable that the time be determined in consideration of the time required for a series of operations of selecting the next CD and inserting it.

This means that until the next CD is inserted,
This is because keeping the light source 7 turned on and brightening the disc insertion / ejection port 4 makes it easier to insert each CD when playing back a plurality of CDs continuously. When a new CD is inserted into the disc insertion / ejection slot 4 before the elapse of a predetermined period of time after the timer 9 starts operating (starts counting), the timer 9 is activated.
Reset. In addition, as this fixed time, CD3
It is preferable that the discharge of is detected by the light receiving element 10 disposed inside the upper surface of the case or the like, and a predetermined time is set based on the detection time.

The specific operation of such a configuration will be described with reference to the time chart of FIG.

First, when the user sets the CD player 1 in an operable state (for example, a state in which a power switch or the like is turned on) (time t1 in FIG. 3), the light source 7 is turned on. As a result, the light from the light source 7 is transmitted to the disc insertion / ejection port 4.
And the area around the disk insertion / ejection port 4 becomes bright. Thereby, even in the dark, the user can easily find the disc insertion / ejection port 4 by relying on the light, and can insert the CD 3 smoothly. Even if the disc insertion / ejection port 4 is provided with a sheet for preventing dust from entering, even if the light from the light source 7 hardly exits to the outside, light leaks from around the sheet or the CD 3 When the disc is slightly entered, the area around the disc insertion / ejection port 4 becomes sharply bright, and the insertion operation of the CD 3 becomes smooth.

Then, the CD 3 is inserted into the disc insertion / ejection port 4
3 and held by the disk drive mechanism 5 (FIG. 3).
At time t2), the holding state detection signal s1 is output and the light source 7
Is turned off, and thereafter the reproduction operation of CD3 is performed. Then, it is assumed that after the reproduction of the CD3 is completed, the CD3 is automatically discharged as shown by A in FIG. 1 (time t3 in FIG. 3). As a result, the discharge state detection signal s2 is output, the light source 7 is turned on, and the light emitted from the light source 7 is applied to the information recording side surface 3a of the CD3.

As a result, the light enters the light transmitting layer 31 of the CD 3, is reflected by the information recording layer 32, and leaks from the side surface 3b of the CD 3. In other words, the light emitted from the light source 7 leaks out from the side surface 3b of the part that protrudes to the outside of the CD 3 in the discharged state (the state indicated by A in FIG. 1) and becomes slightly brighter. The user recognizes that the CD3 has been ejected by the light that leaks out, and the discharged CD3
Can be surely known. Further, the light leaking from the side surface 3b of the CD 3 shines on the CD 3, thereby improving the sense of quality and design of the entire device.

After the reproduction is completed, the light source 7 is similarly turned on even if the user operates the discharge button or the like to discharge the image. Further, even when the user manually stops the reproduction during the reproduction and ejects the CD 3, the light source 7 is similarly turned on.

After the CD 3 is ejected (the state indicated by A in FIG. 1) and the light source 7 is turned on, the timer 9 starts counting and a predetermined period of time (referred to as Δt) is reached. After elapse, the light source 7 is automatically turned off (time t5 in FIG. 3). However, if a new CD 3 is inserted into the disc insertion / ejection slot 4 before the timer 9 starts counting and a predetermined time Δt elapses (for example, time t4 in FIG. 3), the timer 9 starts counting. Is reset, and thereafter, when the above-described operation is performed, that is, when the new CD 3 is held by the disk drive mechanism 5 (corresponding to time t2 in FIG. 3), the light source 7 is turned off, and thereafter, a new CD 3
3 is repeated.

The timing of turning on / off the light source 7 is not set to the timing shown in FIG. 3, and there is no problem even if the light source 7 is slightly shifted back and forth. For example, CD
After the disc 3 has been inserted into the disc insertion / ejection port 4, the light source 7
Is turned off in the example of FIG.
Although the light is turned off when the disk drive 3 is held by the disk drive mechanism 5, an earlier time, for example, the CD3
May be turned off at the same time as the disc is inserted into the disc insertion / ejection port 4.

The C held in the disk drive mechanism 5
When the light source is turned on when D3 is discharged,
In the example of FIG. 3, the light source 7 is turned on when the CD 3 is in the ejected state (the state indicated by A in FIG. 1), but earlier than this, for example, when the CD 3 is held by the disk drive mechanism 5. The light source 7 can be turned on simultaneously with the start of the discharging operation for the CD 3. Further, as described above, the ejection of the CD3 may be detected by the light receiving element 10 and the timer 9 may be operated based on the detection time.

As described above, in this embodiment, by utilizing the fact that the CD 3 has the light transmitting layer 31, the light of the light source 7 is passed through the light transmitting layer 31 so that the discharged state (FIG. Side 3b of CD3 in the state indicated by A in FIG. 1)
By leaking the light of the light source 7 from the, the user can be surely recognized that the CD 3 is in the discharged state or the existence of the CD 3 in the discharged state. In addition,
Light may leak from the lower surface (the information recording side surface 3a) of the CD3, instead of the side surface 3b of the CD3.

By causing light to leak from the light transmitting layer 31 of the CD3, the user can recognize the presence of the CD3 that has been discharged after the reproduction of the CD3 has ended, for example, in a car stereo provided in an automobile running at night. CD3 that can be easily recognized and discharged in the dark
Can be prevented from being accidentally applied to CD3 and damaging CD3 without being noticed.

Also, even before the insertion of the CD 3, the vicinity of the disc insertion / ejection opening 4 becomes bright, so that the insertion of the CD 3 can be performed smoothly even in the dark. further,
Since the amount of light leaking from the CD 3 or the disc insertion / ejection port 4 is small, it does not become an obstacle. Rather, light that is generally visually pleasing, such as orange or green, is slightly emitted, leading to an improvement in design.

Although the above-described embodiment is an example of a preferred embodiment of the present invention, the present invention is not limited to this, and various modifications can be made without departing from the spirit of the present invention. is there. For example, in the above embodiment,
The timing of turning on / off the light source 7 is determined by a signal indicating the state of the CD 3 (a holding state detection signal s1 and a discharge state detection signal s).
The light source 7 was turned on / off by 2).
The timing for turning off the light source 7 in the lighting state or the timing for turning on the light source 7 in the turned off state is as follows.
The timer 9 may be used to automatically turn off or turn on the light after a certain period of time based on a certain state.

For example, the timing for turning off the light source 7 after the CD 3 is inserted into the disc insertion / ejection port 4 is as follows.
It is detected that the CD 3 has been inserted into the disc insertion / ejection port 4, the light is turned off after a predetermined period of time from that point, and the C 3 held by the disc drive mechanism 5 is detected.
When the light source is turned on when D3 is discharged,
It is also possible to detect the start of the ejection operation for the CD 3 held by the disk drive mechanism 5 and to turn on the light after a predetermined period of time based on the start of the ejection operation.

The light source 7 is provided so that its optical axis 7a is perpendicular to the light transmitting layer 31 of the CD 3. The light from the light source 7 is efficiently guided to the disk insertion / ejection port 4 side. As shown in FIG. 4, the optical axis 7a of the light source 7 is set to a CD.
You may make it arrange | position incline to the insertion / discharge port 4 side.

In the above embodiment, the light source 7 is C
Although provided so as to be able to face the information recording side surface 3a of the CD3 below D3, that is, in the discharged state of CD3 (the state shown by A in FIG. 1), the present invention is not limited to this. As shown in FIG. 5, when the CD 3 is ejected (the state indicated by A in FIG. 1), it may be provided at a position facing the side surface 3b of the CD 3. In the case of such a configuration, when the CD 3 is in a discharge state and the light source 7 is turned on, the light enters from one side 3b of the CD 3, passes through the light transmitting layer 31, and leaks from the opposite side 3b of the CD 3. . As a result, the same effect as that described in the above embodiment can be expected, and in this case, light from the light source can be guided to the disk insertion / ejection port 4 side without being reflected at a large angle. Light can often leak from the side surface 3b on the opposite side of the CD3.

In the case of such a configuration, the light reflecting film is not particularly required, and the light is reflected in the light transmitting layer 31 due to the difference in the refractive index between the light transmitting layer 31 and the external space, and the light is reflected on one side of the CD 3. From the side 3b of the CD 3, through the light transmitting layer 31, and leak from the side 3b on the opposite side of the CD3. Thus, in the present invention, depending on the incident angle of light,
The light reflection film is not always necessary.

Furthermore, the CD 3 may be made non-transparent so that light cannot pass through the side surface 3b. Even in this case,
After the light from the light source 7 is guided to the side surface 3b of the CD 3,
It leaks from the information recording side surface 3a of the CD 3 to the outside, not from the side surface 3b. By this light, the shape and position of the CD 3 can be visually recognized, and the same effects as described above, such as easy handling and improved visibility, can be obtained.

1, 4 and 5, the light source 7 is provided inside the case 2 of the CD player 1. In the case where the space in the case 2 has no room, Alternatively, the light source 7 may be provided outside the case. In this case, a hole for transmitting light from the light source 7 is provided in the case 2 (in some cases, a hole is already provided for some reason such as a ventilation purpose), and light from the light source 7 is transmitted to the CD.
The third light transmitting layer 31 may be reliably irradiated.

In the above description, a CD is used as an example of a disk. However, the present invention is not limited to a CD. This type of disk, that is, a light-transmitting layer is provided on at least one surface, and (For example, DV)
D is one of them), and the present invention can be applied to a disk drive device such as a disk player for reproducing these disks.

In the above-described embodiment, a CD player used in a car stereo as a disk drive has been described as an example. However, the present invention is not limited to a car stereo, and there is a possibility that the disc drive is used in a dark environment. It can be applied to all disk drives of a certain device. Further, in the above-described embodiment, the description has been given by taking the disk drive device that performs reproduction as an example, but a disk drive device that can perform not only reproduction but also recording may be used.

[0053]

As described above, claims 1 and 2
The described disk drive device turns on the light source when the disk is in the discharged state, and causes the light from the light source to leak out of the discharged disk. This allows the user to easily recognize that the disc is in the ejected state even in the dark, and prevents the disc being ejected from being accidentally subjected to excessive force and damaging the disc. it can. In addition, the shining of the disk increases the sense of quality and design.

Further, according to the present invention, the light source is turned on even before the disk is inserted into the disk insertion / ejection opening, and the disk is inserted at a predetermined timing (for example, when the disk is inserted). The light source is turned on / off so that the light is turned off at the timing when the disc is held by the drive mechanism).
Since the vicinity of the discharge port becomes bright, the disc can be inserted smoothly. In addition, when the disc is inserted and held by the disc drive mechanism, the light source is turned off, so that power consumption can be reduced. There is no significant effect, and the phenomenon that the illumination light adversely affects the reading operation of the laser light reading pickup does not occur.

According to the fourth aspect of the present invention, after the disk held by the disk drive mechanism is ejected and the light source is turned on, the light source is automatically turned off after a predetermined time. Therefore, power consumption can be suppressed as small as possible. Also, if the fixed time is a time considering the time from the end of processing for one disk to the insertion of the next disk, if the disks are to be successively changed one after another, the next disk is inserted. Until the disc is inserted, the light source can be kept lit and the disc insertion / ejection port can be kept bright until the disc is continuously replaced. Can be.

Further, in the invention according to the fifth aspect, the fixed time until the light source is turned off is determined at least on the basis of the time at which the ejected disc is taken out, so that a long time is required for the disc insertion / ejection opening. Irradiation of the disk can be ensured even if the time is maintained. Also,
Assuming that the fixed time is a time considering the time from the end of the processing for one disk to the insertion of the next disk, after the end of the processing for one disk,
When replacing disks continuously, such as inserting the next disk, keep the light source on until the next disk is inserted. Since the disk can be replaced, the operation of inserting and removing the disk when replacing the disk can be performed smoothly.

In the invention according to claim 6, the light source is provided at a position opposed to the surface of the light transmitting layer of the disk. Therefore, the light source is installed at a position very close to the disk insertion / ejection port. It is also possible to efficiently guide light to the disc insertion slot. In the invention according to claim 7, since the light source is provided at a position facing the side surface of the disk, the light from the light source can be efficiently guided to the disk insertion / ejection port side without being reflected at a large angle. Can be.
