Abstract

PROBLEM TO BE SOLVED: To solve the problem that a locking member gives inserted load and detection of completion of locking cannot be securely performed when a case where a disk, etc., slides is inserted in a casing and locked. SOLUTION: A locking member 11 moves to an unlocking direction, and is held by a holding member 14 until a case M is inserted. When the case M is inserted and the holding member 14 is pushed by the case M, regulation of the locking member 11 by the holding member 14 is canceled, and the locking member 11 moves in the locking direction, and the case M is locked by the locking member 11. Because the locking member 11 is held to the unlocking direction, the loading when inserting the case M is small. Besides, when the locking member 11 moves in the locking direction, a switch 19 operates and output of the completion of locking is obtained.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a recording and / or reproducing apparatus in which a plurality of disks or a single disk, or a case containing a recording medium such as a magnetic disk, a magnetic tape, or a storage element is mounted. .

[0002]

2. Description of the Related Art In a disk selection type disk drive for a vehicle or the like, a case is mounted in a mounting area in a housing. A plurality of disks are housed in this case so as to be able to be pulled out, or a plurality of trays on which disks are placed are housed so as to be able to be drawn out.

A disk drive is provided at a position facing the mounting area. When the disk drive unit moves in the direction in which the disks in the case are arranged and stops, any disk in the case is selected. Then, the selected disk is mounted on the disk drive means from inside the case, and a recording operation and a reproducing operation are performed.

In this type of disk drive, it is necessary to lock the case so that the case is not ejected when the case is inserted into the mounting area. By locking the case in the mounting area, it is possible to prevent the case from moving when the disk is being transferred between the case and the disk drive unit.

A lock device for locking the case includes a lock member that engages with the case when the case is inserted into a mounting region, and a lock member that urges the lock member in the direction of engagement with the case. Generally, a biasing means and a lock releasing member for moving the lock member in a direction in which the lock member is disengaged from the case when discharging the case are provided.

[0006]

However, in the conventional lock device, when the case is pulled out of the mounting area, the lock member is moved in the lock direction by the urging means. Therefore, it is necessary to perform an operation of forcibly inserting the case into the mounting area while moving the lock member in the unlocking direction by an inclined portion or the like formed on the case. In the process of mounting the case in the mounting area, the biased lock member slides on the case from the side.

As described above, the reaction force and the resistance applied to the case when the case starts to be inserted into the mounting area and in the process of inserting the case all the way are increased, and the case cannot be inserted smoothly. Further, when the lock is released and the case is to be discharged from the mounting area, the lock member receiving the urging force may slide on the case to generate a frictional force, and the case may not be discharged smoothly.

In this type of apparatus, it is necessary to detect that the case is securely mounted in the mounting area. Conventionally, the case is directly detected to detect whether or not the case has been mounted to a predetermined position.
However, in this detection method, there is a possibility that a detection output of completion of mounting is output when the lock member is not securely engaged with the case due to an error in the mounting position of the switch.

There is also a method in which when the lock member is engaged with the case, the position of the lock member is detected to recognize that the lock is completed. However, in this detection method, even when the case is ejected to the mounting area, the lock member moves to the lock position by the urging force of the urging member, so that the same detection output as lock completion is output. Occurs.

The present invention solves the above-mentioned conventional problems. When a case is inserted into a mounting area, a lock member does not hinder the operation of inserting the case, and the load at the time of inserting and discharging the case is reduced. It is an object to provide a recording and / or playback device that can.

It is another object of the present invention to provide a recording and / or reproducing apparatus capable of obtaining a mounting completion detection output when a case is mounted in a mounting area and securely locked.

Further, the present invention provides a recording and / or recording apparatus capable of applying a certain urging force to a lock member or the like with a minimum number of parts.
Another object is to provide a playback device.

[0013]

According to the present invention, there is provided a mounting area into which a case containing a recording medium is inserted, and recording and / or recording of data on the recording medium mounted in the mounting area.
Or a recording and / or reproducing apparatus having means for performing reproduction, wherein a lock member that moves in a direction crossing an insertion direction of the case and engages with the case is provided in the mounting area; First urging means for urging the lock member in the lock direction for engaging the case, a lock release member for pressing the lock member in a lock release direction for disengaging the case from the case, and the case is inserted. A holding member that is sometimes pushed in the insertion direction by the case, and a second urging unit that urges the holding member in a discharge direction opposite to the insertion direction, wherein the holding member includes the lock member. When the lock member moves in the lock release direction and the holding member moves in the discharge direction, a regulating portion that regulates movement of the lock member in the lock direction is provided. It is an butterfly.

According to the present invention, when the case is discharged, the lock member is moved and held in the unlocking direction by the holding member. Therefore, when inserting the case, an excessive insertion load is not applied to the case due to the urging force of the lock member. Further, the holding member is moved by being pushed by the case to be inserted, and the movement releases the holding of the lock member. Therefore, when inserting the case, the lock member can be reliably moved in the locking direction.

For example, the restricting portion is a concave portion having an opening directed in the discharge direction, and a convex portion provided on the lock member is held by the concave portion, and the lock member moves in the lock direction. Is regulated.

A single spring member having a pair of elastic arms is attached to the mounting area, and one elastic arm of the spring member is hooked on the lock member to allow the first attachment member to be engaged. The other elastic arm may be hooked on the holding member to serve as the second urging means.

By performing the first urging means and the second urging means with a common spring member, the number of components can be reduced, and the lock member and the holding member can be surely urged by the spring member. . The spring member is a torsion spring, a wire spring, a leaf spring, or the like.

Further, a detection means for detecting that the lock member has reached a position where it engages with the case may be provided.

When the case is mounted, the lock member engages with the case to be in a locked state. By directly detecting that the lock member has reached the locked state,
The lock completion of the case can be reliably detected. Further, since the lock member is positioned in the unlocking direction and held by the holding member until the case is mounted, erroneous detection that a lock completion signal is issued in a state where the case is not locked can be prevented.

For example, in the case, a plurality of discs as the recording medium are removably stored as the recording medium, and at a position facing the mounting area, means for recording and / or reproducing data on and from the recording medium is provided. Disk driving means for driving a disk pulled out of the case is provided, and the disk driving means is raised and lowered in a direction in which the disks are lined up by an elevating drive member so that it can face any disk in the case. The unlocking member is moved in the unlocking direction in a surplus process of the elevating drive member after the case reaches the limit position of the elevating operation.

By operating the unlocking member by the lifting drive member, the device can be configured with a minimum power such as a motor.

The present invention also relates to a case where one disk is stored in a case and only one disk is mounted in a mounting area, and a case where a magnetic disk or a magnetic tape is stored in a case. Alternatively, an element such as an IC or a memory may be housed in a case, and the case may be mounted in a mounting area.

Next, the operation of the above device will be described. When the pinion gear 23 is driven by the power of the motor, the unlocking member 21 rotates clockwise and counterclockwise by meshing with the sector gear 21a. As a result, the lifting drive members 41 and 42 are driven in the Y1-Y2 direction.

FIGS. 1 and 2 show a state immediately after the case M in the mounting area I is discharged. In FIGS. 1 and 2,
The unlocking member 21 rotates to the clockwise end point, the lifting / lowering driving member 41 moves to the end point in the Y1 direction, and the lifting / lowering driving member 42
It is located at the end point in two directions. As shown in FIG. 1, at this time, shafts 32, 32 provided on the disk drive means 31 are provided.
Is located at the Y2 side end within the linear portions 46b, 46b of the lifting drive units 46, 46 of the lifting drive member 41, and the disk drive unit 31 is lowered to the lowermost position. At this time, as shown in FIG. 2, the pressing portion 21b of the unlocking member 21 is in contact with the pressed piece 11c of the locking member 11.

The unlocking member 21 is changed from the state shown in FIGS.
Is slightly rotated in the counterclockwise direction, and when the unlocking member 21 reaches the position (iii) shown in FIG. 2, the pressing portion 21b separates from the pressed piece 11c. At this time,
The lifting / lowering driving member 41 is slightly moved in the Y2 direction by the lock release member 21 to reach the position (ii), and the linear driving portions 46 of the lifting / lowering driving portions 46 of the lifting / lowering driving member 41 are moved.
The end (i) on the Y1 side of b, 46b reaches the position of the shafts 32, 32.

When the unlocking member 21 is at the position (ii), or when the unlocking member 21 is further rotated counterclockwise, the locking member 1
Reference numeral 1 denotes a state in which the lock release member 21 is not restrained. At this time, Y is always applied to the lock member 11 by the elastic arm 18a (first urging means) of the torsion spring 18.
An urging force is applied in one direction (locking direction). However, in a state where the case M is not mounted in the mounting area I, no external force is applied to the holding member 14, and the holding member 14 uses the elastic arm 18b (the second
Is applied in the X2 direction (discharge direction), and the holding member 14 is moved in the X2 direction. Therefore, as shown in FIG. 2, the restricting concave portions 15 of the holding member 14
Is held, and the movement of the regulating protrusion 13 in the Y1 direction is regulated.

As shown in FIG. 2 (iii), when the lock release member 21 is separated from the lock member 11 and the lock member 11 is regulated by the holding member 14,
The case M is mounted on the mounting area I in the X1 direction.

When the case M is inserted in the X1 direction, the lock projection 12 protruding from the guide surface 5 enters the guide groove Ma formed on the bottom surface of the case M. Then, when the case M is inserted, the guide groove Ma continues to be inserted through the lock protrusion 12. At this time, since the lock member 11 is held by the holding member 14, the lock protrusion 12 does not shift in the Y direction with respect to the opening end of the guide groove Ma, and the guide groove is simply inserted by lightly inserting the case M. Lock projection 1 on Ma
2 can enter. Therefore, when the case M is pushed into the mounting area I, the lock protrusion 12 is
There is no need to forcibly enter the inside of a, and the resistance at the initial stage of case insertion is reduced.

When the case M is inserted in the X1 direction, the upper part of the front end of the case M in the X1 direction is connected to the discharge member 27 shown in FIG.
Hit. When the case M is pushed in the X1 direction as it is, the discharge member 27 is also pushed. Since the discharge member 27 is urged in the X2 direction by the spring member, when the case M is pushed in, the insertion resistance in the X2 direction acts on the case M.

When the case M is further inserted from the position shown in FIG. 2 in the X1 direction and immediately before the case M is completely pushed into the mounting area I, the lower part of the front end of the case M is inserted into the insertion pressing piece of the holding member 14. 14c. And case M
At the time of the final pushing operation, the holding member 14 is moved together with X1.
Move in the direction. At this time, the regulating recess 15 formed in the holding member 14 is disengaged from the regulating protrusion 13 in the X1 direction, and the regulation of the lock member 11 is released. The lock member 11 whose restriction has been released tends to move in the Y1 direction by receiving the urging force of the elastic arm 18a.

Immediately thereafter, since the lock engagement groove Mb formed on the bottom surface of the case M reaches the position of the lock protrusion 12, the lock member 11 receiving the urging force of the elastic arm 18a is provided.
Moves in the Y1 direction, and the lock protrusions 12
3B, the case M is locked so as not to come out in the X2 direction, and the locked state shown in FIG. 3 is obtained. At this time,
As shown in FIG. 3, the elastic arm 18b of the torsion spring 18 is pushed in the X1 direction by the holding member 14 moving in the X1 direction, and the torsion spring 18 is deformed to a state where its elastic energy is stored. Therefore, the urging force applied to the lock member 11 by the elastic arm 18a increases, and the lock member 11 is reliably moved in the lock direction. Thus, the two elastic arms 18a and 18b of the spring member move the lock member 11 in the unlocking direction and
Is preferably installed such that the amount of deflection increases with the movement in the insertion direction.

Note that, as shown in FIG.
Moves in the Y1 direction, and the lock projections 12
Is engaged, the actuator 19a of the switch 19 is operated by the detection piece 11d formed on the lock member 11, and a detection output indicating that the lock of the case M is completed is obtained.

As described above, when the case M is not mounted, the lock member 11 moves and is restricted in the unlocking direction by the holding member 14, and moves in the Y1 direction only when the case M is completely mounted. Only at this time, a detection output is obtained from the switch 19. Therefore, the detection output can be obtained only when the case M is completely locked, and the problem that the detection output is erroneously obtained before the lock is completed does not occur.

In a state where the case M is mounted in the mounting area I and locked, the disk in the case M is selectively driven.

The unlocking member 21 is rotated clockwise or counterclockwise by the pinion gear 23. In the disk selecting operation, the unlocking member 21 is moved to the position shown in FIG.
3 is rotated within the angular range of the position of FIG. 3 from the position (iii) shown in FIG. When the unlocking member 21 rotates in the above range, the lifting drive member 41 moves from the position (ii) shown in FIG. 2 to the position shown in FIG. The shafts 32, 32 are guided by the ascending and descending guide portions 46a, 46a which are inclined in a stepwise manner.

The disk drive means 31 moves up and down in the disk selection drive area II under the guidance of the lift guides 46a. When the disk drive means 31 faces one of the selected trays T in the case M, the pinion gear 23 stops, and the lock release member 21 and the elevation drive member 41 stop. During this time, the rear elevation drive member 42 is moved in the opposite direction to the front elevation drive member 41.

When the disk drive means 31 stops, the tray T selected from the case M is moved to the disk drive means 31.
The disc D on the tray T is pressed by the turntable in the disc driving means 31 by the clamper 33 and clamped. Then, the disk D is driven to rotate, and recording / reproduction is performed by the head. The driven disk D is returned into the case M together with the tray T.

When discharging the case M in the mounting area I, the lock release member 21 is rotated clockwise to the final position by the pinion gear 23. At this time, the lifting drive member 41 is driven in the Y1 direction, the shaft 32 is guided to the lowermost position by the lifting guide 46a, and the disk drive unit 31 is moved to the lowermost stage. After the shaft 32 reaches the lowermost part (i) of the elevating guide 46a as shown in FIG. 1, when the elevating drive member 41 further moves in the Y1 direction, the elevating drive 4
Since the lowermost straight portion 46b of 6 slides on the shaft 32, the disk drive means 31 remains stopped at the lowermost stage.

As described above, the lock release member 21 is further moved clockwise in an extra process when the lifting drive member 41 further moves in the Y1 direction after the disk drive means 31 is moved to the lowermost stage by the lift drive member 41. To rotate.

At this time, the pressing portion 2 of the unlocking member 21
1b, the pressed piece 11c of the lock member 11 is pushed in the Y2 direction, the lock member 11 moves in the Y2 direction, and the lock protrusion 12 is disengaged from the lock engagement groove Mb on the bottom surface of the case M to lock the case M. It is released. Since the holding member 14 is urged in the X2 direction by the elastic arm 18b, this urging force is applied to the case M from the holding member 14, and the case M is pushed out in the X2 direction. At the same time, the discharging member 27 shown in FIG. 1 also presses the case M in the discharging direction (X2 direction), so that the case M receiving these forces is discharged from the mounting area I.

In the first step of discharging the case M, the holding member 14 moves in the X2 direction together with the case M, and the regulating protrusion 13 of the lock member 11 is held by the regulating concave portion 15 of the holding member 14. 11 is restricted in the Y1 direction. Therefore, when the lock projection 12 provided on the lock member 11 is located in the guide groove Ma of the case M, even if the pressing portion 21b of the lock release member 21 is separated from the lock member 11, the lock of the lock member 11 is prevented. Protrusion 12
Does not apply a pressing force to the inner surface of the guide groove Ma, so that the case M is smoothly discharged without receiving the sliding resistance with the lock projection 12.

In the present invention, the tray T
A single disk or a plurality of disks may be inserted so as to be able to be pulled out without using any of them. Further, the spring member may be a wire spring or a leaf spring having two elastic arms.

[0070]

As described above, in the present invention, when the case is not inserted, the lock member is regulated in the unlocking direction by the holding member, so that it is not necessary to forcibly move the lock member by the case when inserting the case. The case can be inserted smoothly. Further, it is possible to accurately detect whether or not the lock member is completely locked. Further, it is possible to urge the lock member and the holding member with one spring member.
