JP4201084B2 - Lid opening / closing device for recording / reproducing apparatus - Google Patents

Description

  The present invention relates to a lid opening / closing device that is provided for loading / unloading a cartridge containing a recording medium into / from a recording / reproducing apparatus.

As a specific example of this type of recording / reproducing apparatus, a portable MD player that sets and reproduces a cartridge containing a mini-disc (MD) as a recording medium can be given as an example.
The portable MD player has a main body cabinet, a lid body whose base end is pivotally supported by the main body cabinet so as to be openable and closable, and a cartridge holder attached to the lid body side. The cartridge held by the cartridge holder is rotated by a driving means provided in the main body cabinet, and the cartridge is accessed by an optical pickup unit as an access means provided in the main body cabinet. Some have a magnetic head and can be recorded on a recording medium of a cartridge.

  When the cartridge is loaded into the portable MD player, the cartridge holder insertion slot appears by opening the lid, and the cartridge is manually inserted to the far end, and then the lid is closed. Is connected to driving means provided in the main body cabinet.

  Here, even if the lid is opened, if the lid and the cartridge are in close contact with each other, the cartridge may interfere with the front part of the lid when removing the cartridge, or it may be difficult to remove the cartridge. When the lid is opened, the opening angle of the lid is larger than the opening angle of the cartridge holder. Thus, when the lid is opened, the cartridge is positioned slightly apart from the lid, and the cartridge interferes with the front portion of the lid as compared with the case where the lid and the cartridge are in close contact with each other. This also prevents the cartridge from being easily grasped by hand. In this configuration, when closing the lid, the cartridge is first stored in the main body cabinet at a position before the lid is completely closed, and then the lid is further closed, It will be closed to the closing completion position.

  However, with this configuration alone, even when the lid is open, the cartridge is in a deep position between the lid and the main body cabinet, and thus the drawback that it is difficult to remove the cartridge cannot be completely eliminated.

  In order to completely eliminate this drawback, a cartridge in which the cartridge comes out on the front side of the lid when the lid is opened has been put into practical use. As a specific configuration, a slider that engages with an engagement recess formed in the cartridge is slidable with respect to the cartridge holder, and a mechanism that interlocks the slider with the movement of the lid is provided.

  According to this configuration, when the lid is opened, the slider moves to the near side in conjunction with the movement of the lid, and the near side portion of the cartridge is pulled out to the near side from the lid. This makes it easy to grasp and take out, and the operability is extremely good. In addition, it is not necessary to move the cartridge to the back end of the cartridge holder, it is only necessary to insert the cartridge to a position where the engagement recess of the cartridge engages with the slider. When the lid is closed, the cartridge automatically moves to the back side. Can be driven without any trouble.

  However, if the slider moves to the near side in conjunction with the movement of the lid, the lid is moved from the open position to the near position before the cartridge is stored in the main body cabinet (the closed position and the near position). In addition, the slider and the cartridge are also moved during the closing operation from the pre-closing position to the closing completion position. The length in the depth direction of a recording / reproducing apparatus such as a portable MD player must be made longer by the moving distance up to this point, leading to an increase in the size of the recording / reproducing apparatus.

In response to this, there has been proposed a recording / reproducing apparatus that can perform a cartridge handling operation satisfactorily but does not require a longer dimension in the depth direction (Patent Document 1, etc.).
As shown in FIGS. 8 to 12, the recording / reproducing apparatus includes a first link 101 having one end connected to a link base 100 attached to a side surface of the main body cabinet 90, and the other end of the first link 101. The second link is connected to the cartridge guide piece 104 of the cartridge holder 110 so that the slider 103 is integrally formed on the other end side. 105, a link plate 121 attached to the side surface of the lid 120, a shaft 108 that connects the base end of the cartridge guide piece 104, the base end of the link base 100, and the base end of the link plate 121, and the like. ing. In FIG. 8, 130 is an opening knob for opening the lid 120, and 131 is a lock lever for maintaining the lid 120 in the closed position.

  Here, a long hole 103b is formed in the slider 103 of the second link 105, and a pin 109 attached to the cartridge guide piece 104 is slidably engaged with the long hole 103b. Further, the pin 102 that connects the first link 101 and the second link 105 is slidably supported along the long hole 121 a of the link plate 121. The slider 103 is formed with an engaging convex portion 103 a that is elastically deformed and engaged with the cartridge 111.

  Further, a long hole 101a is formed at a location where the first link 101 is connected to the link base 100, and the first link 101 and the link base are connected via a link support shaft 106 inserted into the long hole 101a. 100 is connected. Further, a helical spring 107 is externally mounted on the link support shaft 106, and ends of the helical spring 107 are engaged with the first link 101 and the link base 100, respectively. The helical spring 107 urges the link base 100 fixed to the main body cabinet 90 in the direction in which the first link 101 opens, that is, the side on which the lid 120 is opened.

  When the lid 120 is closed from the open posture, the first link 101 and the second link 105 are greatly bent as shown in FIG. 11 and FIG. It rotates to the attitude | position with a small bending angle as shown, and the cartridge 111 is pulled in with this in connection with this.

  However, when the lid 120 is closed to the close position as shown in FIG. 12B, the pin 109 attached to the cartridge guide piece 104 comes into contact with the end wall surface of the long hole 103 b of the slider 103. Therefore, the slider 103 and the cartridge 111 are prevented from being pulled further into the back side, and when the lid 120 is closed from the near position before closing to the closing completion position as shown in FIG. While the long hole 101a of the first link 101 slides with respect to the link support shaft 106, the first link 101 moves and rotates so as to be pushed forward.

As a result, the slider 103 and the cartridge 111 move in the front side in conjunction with the movement of the lid 120, and the slider 120 is closed when the lid 120 is closed from the close position to the closed position. 103 and the cartridge 111 can be structured not to move in the pull-in direction, and the recording of a portable MD player or the like can be performed as compared with the structure in which the slider always moves forward in conjunction with the movement of the lid. The dimension in the depth direction of the reproducing apparatus can be formed short, and the recording / reproducing apparatus can be prevented from being enlarged.
JP 2001-319405 A

  However, the recording / reproducing apparatus having the configuration shown in FIGS. 8 to 12 has a structure in which the cover 120 is biased to the opening side by the helical spring 107, and the attachment of the helical spring 107 is provided. If the weight of the lid 120 itself increases or the weight increases when other parts such as a display unit or an operation unit are attached to the lid 120, the lid can be operated even if the opening knob 130 is operated. The body 120 may not be opened well.

  As a method for preventing such a problem, an urging means including a coil spring for urging the slider 103 and the second link 105 in the forward direction along the lid 120 (a direction shown in FIG. 12) is provided. It is possible. However, when this configuration is adopted, the first link 101 connected to the second link 105 is always urged in the B direction. Therefore, even if the long hole 101a is formed in the first link 101, the first link 101 is The link 101 does not slide with respect to the link support shaft 106. As a result, the above-described operation is not performed, and the recording / reproducing apparatus is increased in size or the opening angle when the lid 120 is opened is reduced. This causes problems such as a decrease in operability.

  SUMMARY OF THE INVENTION The present invention solves the above-mentioned problem, and it is possible to maintain good operability even when the weight of a lid or the like is increased, and to open and close the lid opening / closing device of a recording / reproducing apparatus that can be formed with a short depth dimension. Is intended to provide.

  According to a first aspect of the present invention, there is provided a lid opening / closing device for a recording / reproducing apparatus, a main body cabinet, a lid pivotally supported by the main body cabinet so as to be openable and closable, and opening of the main body cabinet in conjunction with the opening of the lid. An insertion port is located between the front end portion of the lid body, a cartridge holder in which a cartridge containing a recording medium is inserted and held, and a cartridge holder slidably attached to the cartridge holder and inserted into the inserted cartridge. A holder-side slider having a cartridge engaging portion to be engaged; a lid-side slider that is slidably mounted in the depth direction on the side of the lid; one end is connected to the side of the main body cabinet, and the other end is A connection that is connected to the lid slider and rotates so that the other end approaches the tip of the lid when the lid is opened. And a biasing means for biasing the lid body in the opening direction by biasing the lid-side slider toward the distal end side of the lid body, and the cam-shaped portion between the holder-side slider and the lid-side slider. And the cartridge is moved by the holder-side slider in accordance with the opening / closing operation of the lid, and the cam-shaped portion is located before the closing position from the opening position of the lid. The holder-side slider engages with the lid-side slider and moves in the cartridge retracting direction, while the holder-side slider is formed in a shape that does not interlock from the close position to the closed position. .

  According to this configuration, the portion corresponding to the slider and the second link in the conventional recording / reproducing apparatus is divided into the holder-side slider and the lid-side slider, and these sliders are connected via the cam-shaped portion. The cam-shaped portion is configured so that the holder-side slider engages and interlocks with the lid-side slider from the opening position of the lid body to the close-to-close position, so that the holder-side slider is interlocked with the movement of the lid body. It can be moved in the depth direction, and operability can be improved. Also, from the position before the closure of the lid to the closure completion position, the holder-side slider is not interlocked because the sliding of the lid-side slider and the holder-side slider is disengaged in the cam-shaped part. The depth direction dimension of the recording / reproducing apparatus can be formed shorter than in the case where the slider always moves in conjunction with the movement.

  In addition, a biasing means such as a coil spring can be used as the biasing means for biasing the lid-side slider toward the distal end side of the lid, and the biasing force to the lid-side slider by this biasing means is the force of the main body cabinet. Since the connecting link is connected to the side surface so that the connecting link rotates in the opening direction with respect to the main body cabinet, the lid is favorably biased to the open side. The portion corresponding to the slider and the second link in the conventional recording / reproducing apparatus is divided into the holder-side slider and the lid-side slider, and these sliders are connected via the cam-shaped portion. The holder-side slider can be satisfactorily controlled between the interlocking state and the non-interlocking state according to the position of the body.

  A cam hole as a cam-shaped portion may be formed in one of the slider on the holder side and the slider on the lid body, and an engaging protrusion for engaging with the cam hole may be provided on the other slider.

  As described above, according to the lid opening / closing device of the recording / reproducing apparatus of the present invention, the holder-side slider can be moved in the depth direction in conjunction with the movement of the lid, and the operability can be improved. The coil spring can be formed as a biasing means by using a biasing means that biases the lid-side slider toward the tip end side of the lid, which can prevent the enlargement of the apparatus by making the depth dimension of the device shorter. Even when the weight of the lid increases, the lid can be opened well and the holder-side slider and the lid-side slider can be connected via the cam-shaped part. Therefore, according to the position of the lid, the holder-side slider can be controlled well between the interlocking state and the non-interlocking state, the reliability is improved, and the shape of the cam shape part can be easily redesigned. Unlinked state and There is also an advantage that the capacity of the control timing and the movement range can be freely set.

The lid body side slider 10 is slidably attached to the side surface portion 6c in the longitudinal direction of the side surface portion (the depth direction of the lid body 2).

  Here, a long hole 6d for slidably guiding the connecting shaft 12b is formed in the side surface portion 6c of the unit panel 6, and a connection attached to the side surface portion 6c of the unit panel 6 is formed in the lid side slider 10. A long hole 10 a into which the shaft 12 c is inserted is formed, and thereby the lid-side slider 10 is supported so as to be slidable in the depth direction inside the side surface of the lid 2.

  Further, a tension spring 11 formed of a coil spring as a biasing means extends over a hook 6f integrally formed near the side surface portion 6c of the unit panel 6 and a locking lever 10b integrally formed with the lid-side slider 10. , And the lid-side slider 10 is urged by the tension spring 11 in the c direction (the tip end side of the lid 2). The connecting shaft 12 b that connects the connecting link 9 and the link base 8 is provided with a helical spring 21 that biases the connecting link 9 in the opening direction with respect to the link base 8. While the urging force of the helical spring 21 is relatively small, the tension spring 11 has a large urging force. The urging force of these urging means, particularly the tension spring, is used. 11, the connecting link 9 is urged in the opening direction, and the lid 2 is urged in the opening direction with respect to the main body cabinet 1.

  Further, a cam hole 10c as a cam-shaped portion is formed in the lid-side slider 10. The cam hole 10 a is adapted to engage with an engaging protrusion 13 a (see FIG. 1 and the like) of the holder-side slider 13 provided in the cartridge holder 5. Here, the cam hole 10c is shaped so that the hole shape on the side closer to the back surface of the lid 2 (the lower side in FIG. 2, that is, the upper side in the arrangement shown in FIG. 1) widens while inclining toward the tip side. Is formed.

  The cartridge holder 5 that holds the cartridge 3 is configured as shown in FIGS. In other words, the support shaft 14a protrudes from the side surface on the base end side of the chassis 14 that holds the drive means for the recording medium, and the cartridge holder 5 is pivotally supported with the support shaft 14a as a center. A holder-side slider 13 that engages with the cartridge 3 is attached to the side surface of the cartridge holder 5 so as to be slidable in the depth direction of the side surface of the cartridge holder 5. Here, the rear end portion of the holder-side slider 13 is divided into an upper piece side and a lower piece side, and the upper end portion of the rear end portion has a rectangular hole 5j formed in the side surface portion of the cartridge holder 5 and A guided portion such as a protruding portion 13c is formed along the peripheral wall portion and the like to guide the holder-side slider 13 in the depth direction, and the lower end portion of the rear end portion is provided on the cartridge 3. An engaging convex portion 13b as a cartridge engaging portion that is elastically deformed and engaged with the mating concave portion 3a (see FIG. 5) is provided. And the cartridge 3 are configured to move integrally. Further, an engagement protrusion 13 a that protrudes to the side is formed at the front end of the holder-side slider 13, and the lid 2 and the unit panel 6 are assembled to the main body cabinet 1 to which the cartridge holder 5 is attached. Thus, the engaging projection 13a of the holder side slider 13 is inserted into the cam hole 10c of the lid side slider 10, and the holder side slider 13 and the lid side slider 10 are engaged.

  As shown in FIGS. 1, 3, 5, and 6, guide bodies 5R and 5L for introducing the cartridge 3 are formed in the insertion opening 5s of the cartridge holder 5, and the guide bodies 5R and 5L In the lower part, in order to prevent erroneous insertion of the cartridge, blocking pieces 5a and 5b extending in a plate shape are formed. Further, leaf springs 5 c and 5 d are integrally formed on the cartridge holder 5, and the cartridge holder 5 is urged in a direction away from the back side of the top surface of the lid 2 by these leaf springs 5 c and 5 d.

  In FIG. 1, reference numeral 22 denotes an opening knob slidably supported on the front surface of the main body cabinet 1, and 23 denotes a lock lever that slides integrally with the opening knob 22, with the lid 2 closed. When the opening knob 22 is slid in a predetermined direction, the lid 2 is unlocked by the lock lever 23.

  In such a configuration, when the lid 2 is closed and the opening knob 22 is slid in a predetermined direction to unlock the lid 2 by the lock lever 23, the lid-side slider 10 by the tension spring 11 is moved forward. The cover-side slider 10 is moved to the near side by the force urging to the side, and the connecting link 9 is rotated in the direction of standing from the main body cabinet 1, so that the cover 2 is opened. When the lid 2 is opened, the urging force of the leaf springs 5c and 5d formed on the cartridge holder 5 holds the cartridge holder 5 in a position slightly separated from the back surface of the lid 2 as shown in FIG. The insertion slot 5 s of the cartridge holder 5 appears between the main body cabinet 1 and the tip of the lid 2.

  In this state, the lid-side slider 10 urged toward the distal end side (eject direction) of the lid 2 by the tension spring 11 is stopped at a position where the connecting shaft 12b contacts the front end of the long hole 6d. The holder-side slider 13 is stopped at a position where the engaging projection 13a is engaged with the lower portion of the cam hole 10c of the lid-side slider 10.

  When the cartridge 3 is inserted in this state, the engaging convex portion 13b of the holder side slider 13 is engaged with the engaging concave portion 3a of the cartridge 3, and the cartridge 3 is about 5 mm from the front end of the lid 2 as shown in FIG. It is held in a posture in which the front end protrudes. As shown in FIG. 7A, the position of the holder-side slider 13 at this time is such that the engaging projection 13a is engaged with the lower portion where the width of the cam hole 10c is the narrowest. The effective length L1 from the engaging portion with 12b to the engaging convex portion 13b of the holder side slider 13 is long.

  Next, when manual operation is performed to close the lid 2, the lid-side slider 10 and the holder-side slider 13 move the tension spring 11 in a state where the effective length is long as the lid 2 rotates in the closing direction. It is quickly pulled into the back of the lid 2 against the urging force. Even during the drawing, there is no loading failure such that the cartridge 3 is sandwiched between the lid 2 and the lock lever 23 of the main body cabinet 1.

  At a position before the completion of the closing of the cartridge 3 (referred to as a position before the closing), as shown in FIG. 7B, the engaging protrusion 13a of the holder-side slider 13 extends from the minimum width portion of the cam hole 10c. In order to engage with the inclined portion 10c ′ (see FIGS. 7A and 7B) continuously connected to the maximum width portion, the engagement between the lid-side slider 10 and the connecting shaft 12b is engaged with the holder-side slider 13. The effective length L2 to the joint convex portion 13b is shorter than the effective length L1.

  Further, when the lid 2 is closed, the engagement protrusion 13a of the holder side slider 13 moves to the maximum width portion of the cam hole 10c as shown in FIG. While the engaging recess 3a of the cartridge 3 is engaged with the projecting portion 13b, the cartridge 3 can be completely loaded up to the mounting position with respect to the turntable 4 in the main body cabinet 1 with the minimum required pull-in amount.

  Here, the effective length L3 from the engaging portion of the lid-side slider 10 with the connecting shaft 12b to the engaging convex portion 13b of the holder-side slider 13 in the state shown in FIG. That is, the effective length is L1> L2> L3.

  Thus, from the position before closing of the lid body 2 to the closing completion position, the engagement of the lid body side slider 10 and the holder side slider 13 in the sliding direction is released in the cam hole 10c as the cam-shaped portion, and the holder side slider Since 13 is not interlocked, the dimension in the depth direction of the recording / reproducing apparatus can be formed shorter than in the case where the slider always moves in conjunction with the movement of the lid. That is, in the closed state, the total effective length dimension (L1-L3) at the time of engagement between the lid-side slider 10 and the holder-side slider 13 is shorter than the middle of the cartridge 3 being retracted. The enlargement of the depth direction of can be avoided.

  In addition, a biasing means (such as a tension spring 11 in this embodiment) that biases the lid-side slider 10 toward the distal end side of the lid 2 can employ a biasing force such as a coil spring. The urging force to the lid-side slider 10 by the above acts on the connecting link 9 connected to the side surface of the main body cabinet 1 so that the connecting link 9 rotates in the opening direction with respect to the main body cabinet 1. Even when the weight of the lid 2 itself increases, or when the weight of the lid 2 increases due to the attachment of other parts such as the liquid crystal display unit 6a and the operation buttons 6b as described above, the lid 2 can be opened. The lid 2 can be satisfactorily opened by operating the opening knob 22.

  When the opening knob 22 is operated from the closed state to instruct the ejecting operation, the lid body 2 is operated in the reverse direction by the urging force of the leaf springs 5c and 5d of the cartridge holder 5 and the tension spring 11 in the opening direction. And the cartridge 3 is ejected, and the front side portion of the cartridge 3 comes out closer to the front side than the lid 2. Therefore, it is easy to grasp the cartridge by hand and the operability is good. Further, when the cartridge 3 is inserted, the cartridge 3 is moved to a position where the engagement recess 3 a of the cartridge 3 engages with the engagement protrusion 13 b of the holder-side slider 13 without moving the cartridge 3 to the back end of the cartridge holder 5. When the lid 2 is closed, the cartridge 5 is pulled into the back side and can be driven without any trouble, and the operability is good.

  And especially according to the said structure, since the holder side slider 13 and the cover body side slider 10 are comprised so that it may interlock | cooperate via the cam hole 10c and the shape of the cam hole 10c can be changed in design easily, the holder side slider 13 There is an advantage that the allowable timing of the movement range and the timing for controlling the lid body-side slider 10 to the linked state and the non-linked state can be freely set.

  In the above-described embodiment, the cam hole 10c is formed in the lid-side slider 10 and the engaging protrusion 13a is provided in the holder-side slider 13. However, the present invention is not limited to this, and the lid-side slider 10 is engaged. A protrusion may be provided to form a cam hole in the holder side slider 13. In addition, the cam-shaped portion is constituted by the cam hole 10c of the through hole and the engaging projection 13a, but may be constituted by a cam-shaped concave portion or convex portion and a portion along the cam-shaped concave portion or convex portion.

  Further, in the above configuration, as shown in FIG. 7B, the engaging projection 13a of the holder-side slider 13 is at the cam hole at the position before the cartridge 3 is moved to the predetermined storage position in the main body cabinet 1. Engage with the inclined portion 10c ′ (see FIGS. 7A and 7B) continuously connected from the minimum width portion to the maximum width portion of 10c, and the holder side slider 13 is relative to the lid side slider 10. In this example, the holder side slider 3 is not linked to the lid body side slider 10 and does not move to the base end side of the lid body 2. However, the present invention is not limited to this. The cartridge 3 is moved to a predetermined storage position in the main body cabinet 1, and the concave portion provided in the cartridge 3 is fitted to the positioning post standing on the main body cabinet 1, so that the cartridge 3 is accurately positioned. At the time of the decided, the holder-side slider 3 may be configured not linked to the lid side slider 10, the recording medium in the cartridge 3 in either case is well mounted on the turntable 4.
