Description

Disc-type record carrier driving apparatus and electronic apparatus having the same

The present invention relates to a disk-type record carrier driving apparatus such as an optical disk apparatus, a magneto-optical disk apparatus, a hard disk apparatus, etc. provided with a sensing element that stores a disk-type record carrier having an information recording surface and can move relative thereto. The present invention relates to an electronic device including a mobile communication system such as a mobile system such as a personal media player, a mobile Internet device, a portable videophone terminal, a PDA, and a micro PC, or an in-vehicle navigator system.

Conventionally, an optical disk device, a magneto-optical disk device, a hard disk device, etc. provided with a sensing element that stores a disk-type record carrier and can move relative to the disk-type record carrier is a disk cartridge that contains a disk-type record carrier having an information recording surface. A main body provided with a spindle motor for storing and opening the disk cartridge in one side wall; and a spindle motor for rotating the disk-type record carrier in the approximate center of the storage; A cartridge pin that protrudes from the main body portion toward the inside of the storage portion and fits into the insertion groove of the disk cartridge and is regulated to a predetermined position where the spindle motor can rotationally drive the disk type record carrier.

For example, the configuration of the positioning means will be described with reference to the perspective view of the disk device in the prior art of FIG. 12. An opening 93 for attaching and detaching the disk cartridge 92 by the chassis 90 and the top cover 91 provided on the upper side is provided on one side wall. A provided dome-shaped storage portion is formed, and a spindle motor (not shown) is disposed in a substantially circular opening 94 at the center of the chassis 90.
When the disk cartridge 92 is inserted from the opening 93 in the Y direction, which is the attaching / detaching direction, first, the hook pin 96 is inserted into the positioning groove 95 formed in an L shape on the bottom surface side of the disk cartridge 92.

Next, when the disk cartridge 92 is further advanced in the Y direction (attachment / detachment direction), the hook pin 96 moves along the guide groove 96a that is opened in an arc shape in the chassis 90, and the L-shape of the positioning groove 95 is obtained. Go into the back side along.
Finally, the front end surface of the disk cartridge 92 comes into contact with the contact surface of the stopper 97 and stops, thereby positioning the disk cartridge 92 in the insertion direction in the Y direction (the direction opposite to the opening 93 side). .
In this state, the positioning protrusions 98 formed on the chassis 90 are also fitted into the positioning grooves 95, and the gap is set small, so that the disk cartridge 92 is positioned in the Y direction. Is called.

The front end surface of the disk cartridge 92 is in contact with the contact surface of the stopper 97, and the position in which the positioning protrusion 98 is inserted into the positioning groove 95 is such that the disk accommodated in the disk cartridge 92 is a spindle motor. The hook pin 96 is inserted into the L-shaped positioning groove 95 so that the disk cartridge 92 is held at this predetermined position without rattling. The disk cartridge 92 is pressed toward the insertion direction in the Y direction (the direction opposite to the opening 93 side).
That is, the positioning projection 98 acts so as not to be displaced in the X direction, the stopper 97 acts so as not to be displaced in the insertion direction in the Y direction, and the hook pin 96 in the direction of the opening side in the Y direction. Is working so as not to be displaced.
With the above configuration, the disk cartridge 92 can be regulated at a predetermined position where the disk accommodated in the disk cartridge 92 can be rotationally driven by a spindle motor (see, for example, Patent Document 1).

JP-A-8-315534

However, in the conventional configuration, the disk cartridge 92 can be regulated to a predetermined position where the disk accommodated in the disk cartridge 92 can be rotationally driven by the spindle motor. When mounted on an electronic device such as a mobile system or an in-vehicle navigator system, when a shock such as a large vertical vibration or a drop is applied, the disk cartridge 92 is not only in the X direction or the Y direction in the storage unit of the disk device described above. Trying to move greatly in the Z direction too.
For this reason, for example, there is a possibility that the disk cartridge 92 is displaced from a predetermined position and becomes inoperable because it is disengaged from the positioning projection 98 that regulates the X direction or the hook pin 96 that regulates the direction of the opening side in the Y direction. 93, the disk cartridge 92 is displaced so as to jump out greatly, and there is a problem that it may collide with the inner wall of the electronic device or other components to be damaged.
In particular, even when the mobile phone is subjected to vibration / drop impact as required for vibration resistance and shock resistance, the disk cartridge 92 is relatively high in the height direction (Z ), And contact with any surface of the chassis 90 and any one of the top covers 91 provided on the upper side of the chassis 90, it is possible to avoid impact loads from being concentrated on one point, There is little damage caused.

On the other hand, even if the height is set such that the positioning protrusion 98 and the hook pin 96 are not removed, the disk cartridge 92 is not fixed in the disk storage portion, so the disk cartridge 92 is not attached to the disk device. If the disc cartridge is displaced relative to the Y direction (attachment / detachment direction), a direction perpendicular thereto (X direction), or a rotation direction (θ direction) on the XY plane when a rotational moment is applied, An impact load is concentrated on the positioning projections 98 and the hook pins 96 serving as the contact portions.
As a result, when the impact load is large, the positioning protrusion 98 and the hook pin 96 are plastically deformed or broken from the base, or the disk cartridge 92 is positioned beyond a predetermined position range to be regulated in the attaching / detaching direction (Y direction). In the direction in which the disc cartridge is displaced and becomes inoperable, the disk cartridge pops out of the opening, or the direction (X direction) or the rotational direction (θ direction) is perpendicular to the attaching / detaching direction, the side wall of the storage unit is plastically deformed, There is a possibility that the disk cartridge 92 does not return to a predetermined position even after receiving an impact, and the rotation drive for recording / reproducing cannot be continued, or the smooth sliding property of the disk cartridge 92 is not secured and the detachment operation cannot be performed. There was also a problem that this occurred.
In particular, in the mobile electronic devices described above, it is very important to realize a reduction in size and weight and a reduction in thickness as well as an improvement in basic performance. The same lightweight and low-rigidity resin material as that of the main body is used, and the size of these restricting members is also required to be smaller along with the downsizing of the disk cartridge 92. Therefore, the above-described new problem arises and the size of the disk device is reduced. It was a big reason to inhibit the conversion.

According to the disk-type record carrier driving apparatus of the present invention, a storage part having an opening for attaching / detaching a disk cartridge provided on one side wall and a storage part are built in, and a disk-type record carrier in the disk cartridge is provided at the approximate center of the storage part. A main body provided with a spindle motor for rotationally driving, and projecting inward from the main body to the inside of the storage part and inserted into the insertion groove of the disk cartridge, and the spindle motor is regulated to a predetermined position where the disk type record carrier can be rotationally driven. The main body is formed with a displacement regulating member that protrudes so as to close the opening of the storage portion and prevents the disk cartridge from exiting the opening.
With this configuration, it is possible to prevent the disc cartridge from being displaced so as to protrude from the opening of the storage portion in the attaching / detaching direction (Y direction) even when subjected to a large vibration / impact.
Further, if the position where the displacement restricting member is formed is set within a range in which the cartridge pin is elastically deformed when the disk cartridge is displaced in the attaching / detaching direction (Y direction), the cartridge pin may be plastically deformed or broken from the root. Can also be prevented.

According to the disc type record carrier driving device of the present invention, the displacement regulating member is separated from the disc cartridge regulated at a predetermined position by a larger distance than the gap in the attaching / detaching direction between the insertion groove and the cartridge pin in the attaching / detaching direction. It is characterized by being formed at a position.
Normally, the disk cartridge insertion groove is set to be larger than the outer diameter of the cartridge pin in advance to facilitate attachment / detachment, and a gap is provided between the disk cartridge insertion groove and the cartridge pin. Has a backlash.
However, according to this configuration, even if the play is loose, the displacement restricting member is not interfered with, so that a smooth fit between the disc cartridge and the cartridge pin can be ensured.

According to the disc type record carrier driving device of the present invention, the displacement regulating member is formed with a height larger than the gap in the height direction between the upper surface of the disc cartridge regulated at a predetermined position and the upper wall of the storage portion. It is characterized by this.
With this configuration, even if the impact of vibration or dropping is large and the disc cartridge is displaced in the height direction (Z direction) in the storage portion, the height of the displacement regulating member is larger than the gap in the height direction. Displacement that jumps over the displacement regulating member can be prevented.

According to the disk type record carrier driving apparatus of the present invention, a plurality of displacement regulating members are formed so as to be substantially symmetrical with respect to the center line in the width direction of the opening.
With this configuration, in particular, even when the disk cartridge is displaced so as to protrude greatly from the opening in the attaching / detaching direction (Y direction) in the storage unit due to large vibrations or dropping impacts, the displacement regulating member is not open to the disk cartridge. Since the contact is made evenly in the width direction, the rotational moment does not act due to the movement of the center of gravity of the disk cartridge, so that it is possible to prevent the corner portion of the disk cartridge from colliding with the side wall of the storage portion and plastically deforming the side wall.

According to the disc-type record carrier driving apparatus of the present invention, the contact surface of the displacement regulating member with the disc cartridge is shaped along the outer shape of the disc cartridge.
With this configuration, the disk cartridge is greatly displaced toward the opening side in the attaching / detaching direction (Y direction) in the storage portion, and the moment of contact with the displacement restricting member does not contact the surface and concentrate the impact load on one point. Further, it is possible to prevent the contact portion of either the disc cartridge or the displacement regulating member from being damaged.

According to the disk-type record carrier driving apparatus of the present invention, a storage part having an opening for attaching / detaching a disk cartridge provided on one side wall and a storage part are built in, and a disk-type record carrier in the disk cartridge is provided at the approximate center of the storage part. A main body provided with a spindle motor for rotationally driving the disk, and projecting from the main body toward the inside of the storage part and inserted into the insertion groove of the disk cartridge, and the spindle motor is in a predetermined position where the disk type record carrier can be rotationally driven. The main body is formed with a deformation restricting member that protrudes outside the side wall of the storage unit and prevents deformation of the side wall of the storage unit.
With this structure, when a large vibration or impact is applied, a rotational moment acts on the disk cartridge, and the corner portion is displaced in a direction (X direction) perpendicular to the width direction of the opening of the storage portion. It is possible to prevent the side wall of the glass from being deformed or damaged.
Further, if the position where the deformation restricting member is formed is set within a range where the cartridge pin is elastically deformed when the corner portion of the disk cartridge is displaced in a direction (X direction) perpendicular to the width direction of the opening of the storage portion, It is also possible to prevent the cartridge pin from being plastically deformed or broken from the base.

According to the disc type record carrier driving apparatus of the present invention, the deformation restricting member protrudes to the opening side from the side wall of the storage portion in the attaching / detaching direction of the disc cartridge.
With this configuration, when a large moment of vibration or impact is applied to the disc cartridge and its side surface hits the opening of the side wall of the storage unit and jumps out, the impact load may be applied multiple times. Although it is large, even in such a case, it is possible to effectively prevent the side wall from being plastically deformed.

According to the disk type record carrier driving apparatus of the present invention, the distance between the deformation regulating member and the side wall of the storage unit is set such that the side wall of the storage unit does not undergo plastic deformation even if the side wall of the storage unit abuts against the deformation regulation member. It is a feature.
With this configuration, even if the side wall of the storage part is elastically deformed instantaneously when subjected to large vibrations / impacts, it does not reach plastic deformation, so the original shape is easily restored, so such impacts The disk cartridge can be easily returned to the specified position even after receiving an impact, and not only can the rotation drive for normal recording and playback be continued, but also the smooth sliding property of the disk cartridge can be ensured, which also affects the mounting and dismounting operations. It can be greatly reduced.

According to the disk-type record carrier driving apparatus of the present invention, a storage part having an opening for attaching / detaching a disk cartridge provided on one side wall and a storage part are built in, and a disk-type record carrier in the disk cartridge is provided at the approximate center of the storage part. A main body provided with a spindle motor for rotationally driving, and projecting inward from the main body to the inside of the storage part and inserted into the insertion groove of the disk cartridge, and the spindle motor is regulated to a predetermined position where the disk type record carrier can be rotationally driven. A displacement regulating member that protrudes to close the opening of the storage portion and prevents the disk cartridge from coming out of the opening, and protrudes outside the side wall of the storage portion. And a deformation restricting member for preventing the deformation of the material.
This configuration prevents the disc cartridge from being displaced so as to protrude from the opening of the storage portion in the attaching / detaching direction (Y direction) even when subjected to large vibrations / impacts, and a rotational moment acts on the disc cartridge. Even when the disk cartridge is displaced in the rotation direction (θ direction), it is possible to prevent the side wall of the storage unit from being deformed by the collision with the corner part of the disk cartridge.
In particular, in the case of a drop impact, it is expected that a large impact load will continuously be applied in two directions at right angles to each other because it collides with the floor surface multiple times. Forming the displacement restricting member and forming the deformation restricting member on the side wall located perpendicular to the width direction of the opening is a very effective configuration for greatly reducing the impact of the drop impact.

According to the electronic apparatus of the present invention, any one of the above-described disk-type record carrier driving devices is provided.
With this configuration, even electronic devices that are small and light and thin that are easily affected by vibrations and shocks are affected by large changes such as popping out of the disk cartridge of the disk-type record carrier driving device mounted inside. Accidents such as damage to the internal components of the device, damage to the optical disk, or loss of optical disk attachment / detachment due to deformation of the storage part are prevented, and the effects of vibration and shock are greatly reduced, resulting in higher reliability. Can be provided.

According to the disk-type record carrier driving apparatus according to the present invention, it is possible to prevent the disk cartridge from being greatly displaced from the storage portion even when subjected to a large vibration / impact, despite being downsized and lightweight and thin.
According to the electronic apparatus provided with the disk-type record carrier driving apparatus according to the present invention, the influence of vibration and impact can be largely prevented despite the reduction in size and weight and thickness of the electronic apparatus, thereby ensuring higher reliability.

First, the disk-type record carrier driving apparatus 11 according to the first embodiment of the present invention shown in FIG. 1 has a disk cartridge C containing a small-diameter optical disk D having a diameter of about 32 mm indicated by a broken line as a disk-type record carrier. This is a state before being inserted into the storage unit 12 and stored in the built-in storage unit 12.
As its configuration, there is a storage section 12 in which a disk cartridge C containing an optical disk D having an information recording surface is first inserted from the front opening 12a and is further slid along the side wall 12b.
Next, the storage unit 12 is closed while rotating with the side opposite to the opening 12a as a support shaft in a state in which the disk cartridge C is stored, but the main body unit 13 incorporates the storage unit 12 to store the disk cartridge. It has a mechanism for restricting C to a predetermined position of the main body 13, and when the storage unit 12 is closed (see FIG. 2), it is positioned substantially at the center of the storage unit 12 and rotationally drives the optical disk D in the disk cartridge C. The spindle motor 13f for controlling the rotation of the spindle motor 13f, the optical pickup 13g for converting optical information into electrical information through laser light in a non-contact manner while moving in the radial direction around the spindle motor 13f, and external control The main part 13b including components such as a hardware part (not shown) for performing communication of the above and the main components from the upper chassis 13 And it is configured so as to sandwich between the bottom chassis 13c from the lower side.
And the front-end | tip part of the flat connection part 13d which protruded from the predetermined position of the side surface of the main-body part 13 is hold | gripped, and the anti-vibration part 14f which protrudes only predetermined distance from the front-end | tip surface is provided. As the material, it is more preferable to select an elastomer as a material that absorbs vibration and impact.

In other words, the disk-type record carrier driving device 11 includes a storage unit 12 for storing the disk cartridge C, and a main body provided with a spindle motor 13f that rotates and drives the optical disk C in the approximate center of the storage unit 12. It is comprised from the part 13, and the anti-vibration part 14f which protruded from the predetermined position of the side surface of the main-body part 13, etc.
Here, the flat connecting portion 13d is provided so as to protrude from the side surface of the main portion 13b by integral molding using a resin material considering heat resistance such as PPE, PBT, ABS, and PC.

When the disk cartridge C is slid from the opening 12a in front of the storage unit 12 and is stored in the storage unit 12 in a state where the disk cartridge C is stored in the storage unit 12, the main unit 13b is closed. The cartridge pin 15 is inserted into the insertion groove C1 formed so as to penetrate the disk cartridge C and is regulated to a predetermined position where the spindle motor 13f can rotationally drive the optical disk D, with respect to the center line in the width direction of the opening 12a. It is provided so that it may protrude toward the inner side of the storage part 12 in two places which become substantially symmetrical.

Further, the cartridge pin 15 is formed of a resin material integrally with the main portion 13b so as to be easily inserted and guided, and has a cylindrical shape with a pointed tip formed at the tip thereof.
That is, when the storage portion 12 is closed while rotating with the side opposite to the opening 12a as a support shaft in a state in which the disc cartridge C is stored, the insertion groove C1 of the cartridge disc and the cylindrical portion of the cartridge pin 15 Since the gap is set to be as small as possible, the spindle motor 13f is restricted to a predetermined position where the optical disk D can be rotationally driven.

Further, an upper portion of the main portion 13b constituting the main body portion 13 protrudes to close the opening 12a when the storage portion 12 is closed (see FIG. 2), thereby preventing the disc cartridge C from exiting the opening 12a. Displacement restricting members 16 are formed at two locations that are substantially symmetrical with respect to the center line in the width direction of the opening 12a.
With such an arrangement, even when the disk cartridge C is displaced so as to protrude greatly from the opening 12a in the attaching / detaching direction (Y direction) in the storage portion 12, the displacement regulating member 16 is greatly affected by vibration or dropping. Since the disk cartridge C is uniformly abutted in the width direction of the opening 12a, the rotational moment does not act due to the movement of the center of gravity of the disk cartridge C. Therefore, the corner portion Cc (see FIG. 3) of the disk cartridge C is the storage portion. It is possible to prevent the side wall 12b from colliding with the side wall 12b and causing the plastic deformation of the side wall 12b.

Further, on the upper part of the main part 13b constituting the main body part 13, deformation regulating members 17 for preventing the deformation of the side wall 12b of the storage part 12 when the storage part 12 is closed (see FIG. 2) are provided on both sides. It is formed so as to protrude outside the side wall 12b.
Here, each of the displacement regulating member 16 and the deformation regulating member 17 is formed by integral molding with the same resin material as that of the main portion 13 like the cartridge pin 15.

Next, in the state shown in FIG. 2, the disk cartridge C shown in FIG. 1 is stored in the storage portion 12, the cartridge pin 15 described above is inserted into the insertion groove C1 of the disk cartridge C, and the spindle motor 13f is connected to the optical disk. This is a state in which D is regulated at a predetermined position where D can be rotationally driven.
At the same time, this state is a state in which the operation of reproducing the information from the information recording surface of the optical disc D or newly recording the information on the recording surface is possible. The cartridge C is defined at a predetermined position in two directions, ie, the width direction (X direction) of the opening 12a and the attaching / detaching direction (Y direction) positioned at right angles thereto.
As is clear from this figure, the disc type record carrier driving device 11 is a mobile system such as a personal media player, a mobile Internet device, a mobile phone, a portable videophone terminal, a PDA, a micro PC, or a vehicle-mounted one. In order to facilitate mounting on a thin electronic device including a mobile communication system such as a navigator system, the main body 13 of the present device has a flat, substantially rectangular parallelepiped shape having all six surfaces.

Here, the opening 12a side of the storage unit 12 connected in a direction perpendicular to the upper surface of the upper chassis 13a and the lower surface of the lower chassis 13c constituting the pair of main surfaces (in this figure). The right front side surface and the back side surface located on the opposite side constitute a pair of main side surfaces, and are connected in parallel to each other in a direction perpendicular to the main surface and the main side surfaces. The surface on the side where 13e is locked and the surface positioned on the opposite side constitute a pair of sub-side surfaces.
Here, the locking portion 13e is for controlling the angle at which the storage portion 12 is opened to the maximum by engaging with the trapezoidal opening of the lower chassis 13c constituting the sub-side surface. The opening / closing angle of the storage unit 12 is determined by appropriately setting the opening.
The main side surface and the sub-side surface on the front side have a substantially L-shaped vibration isolating portion 14f as viewed from the main surface side, and the main side surface on the back side has a substantially I-shaped vibration isolating portion 14r as viewed from the main surface side. (See FIG. 3) is provided so as to cover the tip of the connecting portion 13d protruding from each side surface.

Next, FIG. 3 shows a plan view in which upper movable parts such as the upper chassis 13a and the storage unit 12 described above are removed for more detailed explanation.
In addition, the positional relationship between the disk cartridge C and the displacement restricting member 16 and the deformation restricting member 17 formed on the main portion 13b is shown, but the cartridge pin 15, the displacement restricting member 16 and the deformation restricting member 17 are shown for easy understanding. It is painted black.

As is clear from this figure, the state where the disk cartridge C is regulated at a predetermined position is two places on the corner Cc side on the arcuate front end surface C2 side of the arcuate shape of the disk cartridge C which is the lower side in this figure. The cartridge pin 15 formed so that a gap with the insertion groove C1 provided in the substantially circular shape is as small as possible is inserted, and the cartridge pin 15 is positioned substantially at the center of the insertion groove C1. It is.
In this state, a gap, which is a dimensional difference between the inner diameter of the insertion groove C1 and the outer diameter of the cartridge pin 15, is set to about 0.1 mm, for example, so that the disc cartridge C is attached to and detached from the main portion 13b. Predetermined positioning is performed in two directions (Y direction) and a direction (X direction) perpendicular thereto.

The main portion 13b has an opening 12a (see FIG. 2) of the storage portion 12 at a position away from the arcuate front end surface C2 side of the disc cartridge C which is the lower side in the drawing in the attaching / detaching direction (Y direction). Displacement restricting members 16 that protrude so as to close and prevent the disk cartridge C from exiting the opening 12a are formed at two locations.
As will be described in detail later, as shown in this figure, the displacement regulating members 16 formed at two locations are arranged so as to be substantially symmetrical with respect to the center line in the width direction of the opening 12a. The displacement regulating member 16 is also formed at a position away from the front end face C2 of the disk cartridge C in the attaching / detaching direction (Y direction) by a distance larger than the gap in the attaching / detaching direction (Y direction) between the insertion groove C1 and the cartridge pin 15. ing.

The displacement regulating member 16 is formed at a height larger than the gap in the height direction (Z direction) between the disk cartridge C mounted in the storage unit 12 and the inside of the storage unit 12. The contact surface with the disk cartridge C has a shape along the outer shape of the disk cartridge C (see FIG. 6B).

Next, FIG. 4 also shows a cross section of the upper wall 12c of the storage unit 12 in order to show the relationship between the disk cartridge C and the displacement regulating member 16 in detail.
As described above, the cartridge pin 15 is integrally molded with the main portion 13b of a resin material so as to be easily guided by being inserted into the insertion groove C1 of the disk cartridge C, and has a pointed head formed at the tip thereof. Yes.
In addition, since the disk cartridge C is regulated at a predetermined position, the cartridge pin 15 is positioned substantially at the center of the insertion groove C1, but the insertion groove C1 of the cartridge disk C and the cylinder of the cartridge pin 15 are arranged. The gap S with the shape portion is set so as to have a predetermined backlash for easy attachment / detachment.
Accordingly, the gap S is equal to the dimensional difference between the inner diameter Dc of the insertion groove C1 of the disk cartridge C and the outer diameter Dp of the cartridge pin 15 in a state where the spindle motor 13f is regulated at a predetermined position where the optical disk D can be rotationally driven. , S = Dc−Dp.

The displacement restricting member 16 is also integrally formed with the main portion 13b of a resin material, and is formed at a position separated from the arc-shaped front end face C2 side of the disk cartridge C by a distance Gk in the attaching / detaching direction (Y direction). However, it is larger than the gap S and is formed at a position where Gk> S is satisfied.
That is, as described above, if the gap S, which is the dimensional difference between the inner diameter Dc of the insertion groove C1 and the outer diameter Dp of the cartridge pin 15, is set to about 0.1 mm, the distance Gk is set to a larger value. Is set.
Further, the height Hk of the displacement regulating member 16 in the height direction (Z direction) with respect to the lower surface C3 of the disc cartridge C regulated at a predetermined position is stored with the upper surface C4 of the disc cartridge C in that state. It is formed to be larger than the gap Gc in the height direction (Z direction) with the upper wall 12C of the portion 12.

Next, FIG. 5A shows that the disc cartridge C is provided with a gap S between the insertion groove C1 of the disc cartridge C and the cartridge pin 15, and the disc cartridge C is attached and detached in the attaching / detaching direction (Y direction). In this figure, the disk cartridge C is displaced to the opening 12a side of the storage portion 12 within the range of the backlash.
Here, as described above, the displacement regulating member 16 is formed at a position away from the arcuate front end surface C2 side of the disk cartridge C by a distance Gk that satisfies the relationship Gk> S in the attaching / detaching direction (Y direction). Therefore, as shown in the figure, even if the back and forth direction (Y direction) rattles toward the opening 12a, it does not come into contact with the displacement restricting member 16 and does not receive the interference, so the disk cartridge C and the cartridge pin The smooth insertion property between 15 can be ensured.

FIG. 5B shows a state in which the disk cartridge C is greatly displaced in the opening 12a side and the height direction (Z direction) of the storage unit 12 due to a large vibration or impact.
In such a state, the impact load is not only concentratedly applied to the cartridge pin 15 from the insertion groove C1, but the disk cartridge C is greatly displaced in the height direction (Z direction) by the repulsive force.

Therefore, as shown in the figure, the cartridge pin 15 is deformed so as to be bent largely from the base portion, and the upper surface C4 of the disk cartridge C is violently colliding with the upper wall 12c of the storage portion 12, while the left side in FIG. However, the front end surface C2 is prevented from coming into contact with the contact surface 16a of the displacement regulating member 16 and coming out.
Further, the height Hk of the cartridge pin 15 is formed at a height larger than the gap Gc in the height direction between the upper surface C4 of the disk cartridge C and the upper wall 12c of the storage portion 12, and therefore the height direction (Z Even if it is displaced so as to be lifted by a distance corresponding to the gap Gc in the direction), it is prevented from jumping over the displacement regulating member 16.

On the other hand, FIG. 6A shows the same state as FIG. 5A, but the cartridge pin 15 and the displacement regulating member 16 are shown in black.
Here, the front end surface C2 of the disk cartridge C is displaced toward the displacement regulating member 16, and the upper surface C4 violently collides with the upper wall 12c of the storage portion 12 as described above. The cartridge pin 15 is in a state in which it is inscribed in the insertion groove C1 while maintaining the roundness because it is a displacement within the range of looseness. It shows that.

6 (b) shows the same state as FIG. 5 (b), but the cartridge pin 15 is deformed so as to be largely bent down from the base portion, so that the roundness when viewed from above is shown. Is not maintained. In this figure, the disk cartridge C tries to jump out to the lower opening 12a side, but its front end surface C2 comes into contact with the contact surface 16a of the displacement regulating member 16, so that it is prevented from jumping out.
Further, as apparent from this figure, the contact surface 16a of the displacement regulating member 16 with the disk cartridge C has a shape along the outer shape of the disk cartridge C. Therefore, the displacement regulating member 16 and the disk cartridge At the moment of contact, the impact load is not concentrated on one point due to surface contact, and it is possible to effectively prevent the contact portion of either the disk cartridge C or the displacement regulating member 16 from being damaged.

As described above, the disk-type record carrier driving device 11 according to the first embodiment of the present invention incorporates the storage section 12 provided with the opening 12a for attaching / detaching the disk cartridge C on one side wall, and the storage section 12, and stores the storage section 12 therein. A main body portion 13 provided with a spindle motor 13f for rotationally driving the optical disc D at the approximate center of the portion 12, and projecting from the main body portion 13 toward the inside of the storage portion 12 into the insertion groove C1 of the disc cartridge C. 13f includes a cartridge pin 15 that restricts the optical disk D to a predetermined position where the optical disk D can be rotationally driven. The main body 13 protrudes so as to close the opening 12a of the storage section 12, and prevents the disk cartridge C from exiting the opening 12a. The displacement regulating member 16 is formed.

With this configuration, it is possible to prevent the disc cartridge C from being displaced so as to protrude from the opening 12a of the storage unit 12 in the attaching / detaching direction (Y direction) even when subjected to a large vibration / impact.
Further, if the position where the displacement restricting member 16 is formed is set within a range in which the cartridge pin 15 is elastically deformed when the disk cartridge C is displaced in the attaching / detaching direction (Y direction), the cartridge pin 15 may be plastically deformed or rooted. It is also possible to prevent breakage.
Further, the displacement regulating member 16 is moved from the disc cartridge C regulated at a predetermined position by a distance larger than the gap S (= Dc−Dp) in the attaching / detaching direction (Y direction) between the insertion groove C1 and the cartridge pin 15. It is the structure formed in the position away in the attachment / detachment direction (Y direction).

Usually, in order to facilitate attachment / detachment, the insertion groove C1 of the disk cartridge C is set in advance to be larger than the outer diameter Dp of the cartridge pin 15, and the gap S (= Dc−) between the insertion groove C1 of the disk cartridge C and the cartridge pin 15 is set. Dp) is provided, and the disc cartridge C is loose in the attaching / detaching direction (Y direction) by the gap S.
However, with this configuration, even if there is a backlash, the displacement restricting member 16 is not affected, so that a smooth fit between the disk cartridge C and the cartridge pin 15 can be ensured.

Further, the displacement restricting member 16 is formed with a height Hk larger than the gap Gc in the height direction between the upper surface C4 of the disc cartridge C restricted to a predetermined position and the upper wall 12c of the storage portion 12. Yes.
With this configuration, even if the disk cartridge C is displaced in the height direction (Z direction) in the storage portion 12 with a large vibration or drop impact, the height Hk of the displacement regulating member 16 is larger than the height gap Gc. Therefore, the displacement which jumps over the displacement regulating member 16 can be prevented.

In addition, a plurality of displacement regulating members 16 are formed so as to be substantially symmetric with respect to the center line in the width direction of the opening 12a.
With this configuration, in particular, even when the disk cartridge C is displaced so as to protrude greatly from the opening 12a in the attaching / detaching direction (Y direction) in the storage portion 12 due to a large vibration or drop impact, the displacement restricting member 16 can move the disk cartridge C. Since the disk cartridge C is abutted evenly in the width direction of the opening 12a, no rotational moment is applied by the movement of the center of gravity of the disk cartridge C, so that the corner portion Cc (see FIG. 3) positioned in the insertion direction of the disk cartridge C is formed. It is possible to prevent the side wall 12b from colliding with the side wall 12b of the storage unit 12 from being plastically deformed.

Further, the contact surface 16 a of the displacement regulating member 16 with the disk cartridge C has a configuration along the outer shape of the disk cartridge C.
With this configuration, the disk cartridge C is greatly displaced toward the opening 12a in the attaching / detaching direction (Y direction) in the storage portion 12, and the impact load is concentrated at one point by surface contact at the moment of contact with the displacement regulating member 16. Therefore, it is possible to prevent the contact portion of either the disk cartridge C or the displacement regulating member 16 from being damaged.

In the case of the first embodiment, for example, the total weight of the main body 13 of the disc-type record carrier device 11 is about 25 g, the outer dimensions of the main body 13 are about 44 mm in width, about 43 mm in depth, and high in height. The disk cartridge C is set to about 9.5 mm, the weight of the disk cartridge C is set to 3.8 g, the inner diameter Dc of the insertion groove C1 is set to 1.71 mm, and the outer diameter Dp of the cartridge pin 15 is set to 1.6 mm. If the gap Gc in the height direction (Z direction) between the upper surface C4 of the storage unit 12 and the upper wall 12c of the storage unit 12 is set to about 0.35 mm, the lower surface C3 of the disk cartridge C restricted to a predetermined position The height Hk of the displacement restricting member 16 in the height direction (Z direction) as a reference is set in a range of about 1.0 to 2.3 mm, and the displacement restricting member 16 is an arc of the disk cartridge C. And more preferably set in a range of about 0.11 ~ 0.5 mm distance Gk shaped for the front end face C2 side from detaching direction (Y-direction).

Next, as shown in FIG. 7, the cartridge pin 15 is integrally molded with a main portion 13b of a resin material to form a cylindrical shape, and a pointed head is formed at the tip thereof, so that the disk cartridge C is regulated at a predetermined position. Therefore, the disk cartridge C is positioned substantially at the center of the insertion groove C1.
Further, in order to ensure smooth slidability of the disk cartridge C and facilitate attachment / detachment work, the disk cartridge C is placed on the upper surface of the bottom wall 12d inside the storage portion 12, and stored with the side end surface C5. Between the side wall 12b of the portion 12 and between the upper surface C4 and the upper wall 12c of the storage portion 12 in a predetermined gap Gs and a height direction (Z direction) as appropriate in the X direction perpendicular to the attaching / detaching direction (Y direction). A predetermined gap Gc is provided as appropriate.
The main portion 13b is formed with a deformation restricting member 17 that protrudes outside the side wall 12b of the storage portion 12 and prevents the deformation of the side wall 12b of the storage portion 12, but the deformation restricting member 17 and the storage portion 12 The distance Gh from the side wall 12b is set to a distance at which the side wall 12b is not plastically deformed even when the side wall 12b of the storage portion 12 contacts the deformation regulating member 17.

Further, as shown in FIG. 8A, the inner diameter Dc of the insertion groove C1 of the disk cartridge C is between the insertion groove C1 of the disk cartridge C in which the disk cartridge C is stored in the storage unit 12 and the cartridge pin 15. A gap S having a relationship of S = Dc−Dp equal to the dimensional difference with the outer diameter Dp of the cartridge pin 15 is provided, and the disc cartridge C has a backlash in the width direction (X direction) of the opening 12a by the gap S. However, the disk cartridge C is displaced toward the side wall 12b of the storage unit 12 within the range of the play.
Even in this state, the gap between the side end surface C5 of the cartridge C and the side wall 12b of the storage portion 12 becomes small, but the side end surface C5 and the side wall 12b do not interfere with each other, and stress that gives deformation to the side wall 12b also acts. Not done.

FIG. 8B shows a corner portion Cc (front end surface C2 side of the arc-shaped front end face C2 which is greatly displaced in the rotational direction (θ direction) due to a rotational moment acting on the disk cartridge C in response to a large vibration or impact. FIG. 9 (a) shows a state in which it collides with the side wall 12b.
In such a state, the impact load is not only concentratedly applied to the cartridge pin 15 from the insertion groove C1, but the disk cartridge C is greatly displaced in the height direction (Z direction) by the repulsive force.

Therefore, as shown in the figure, the cartridge pin 15 is deformed so as to be bent greatly from the base portion, and the upper surface C4 of the disk cartridge C collides with the side wall 12b while colliding with the upper wall 12c of the storage unit 12 violently. Is elastically deformed.
Further, a large deformation stress is applied until the side wall 12b is plastically deformed. However, the side wall 12b abuts against the abutment surface 17a of the deformation regulating member 17, and the side wall 12b is prevented from further deformation. Yes.
Here, the distance Gh (see FIG. 7) between the deformation regulating member 17 and the side wall 12a of the 12 storage portion is a distance at which the side wall 12b does not plastically deform even if the side wall 12b of the storage portion 12 abuts against the deformation regulating member 16. Although it is set, the storage unit 12 may be appropriately set depending on, for example, a metal material such as SUS300 series, SUS400 series, SECC, or SPCC, a plate thickness, a dimension, and the like.

On the other hand, FIG. 9A shows the same state as FIG. 8A, but for the sake of clarity, the sectional view of the side wall 12b is shown and the cartridge pin 15 and the displacement regulating member 17 are blackened. Filled out.
Here, the deformation restricting member 17 protrudes toward the opening 12a, which is the lower side in the drawing, from the side wall 12b of the storage portion 12 in the attaching / detaching direction (Y direction).
Here, the disc cartridge C has a backlash in the width direction (X direction) of the opening 12a by the gap S described above, but the disc cartridge C is displaced toward the side wall 12b of the storage unit 12 within the backlash range. Is shown.
Even in this state, the gap Gs between the side end surface C5 of the cartridge C and the side wall 12b of the storage portion 12 is reduced, but the side end surface C5 and the side wall 12b do not interfere with each other, and stress that gives deformation to the side wall 12b is not generated. Not working.

9 (b) shows the same state as FIG. 8 (b), but a large moment or vibration is applied to the disk cartridge C due to a large vibration or shock, and the displacement is greatly displaced in the rotational direction (θ direction). The corner portion Cc on the front end face C2 side of the arc shape collides with the side wall 12b.
Therefore, since the cartridge pin 15 is deformed so as to be bent greatly from the base portion, the roundness when viewed from above is not maintained.
The disc cartridge C collides with the side wall 12b and elastically deforms it, and further attempts to apply a large deformation stress until plastic deformation, but the side wall 12b comes into contact with the contact surface 17a of the deformation regulating member 17. So it is prevented from further deformation.

As described above, the storage portion 12 having the opening 12a for attaching and detaching the disk cartridge C provided on one side wall, and the storage portion 12 are built in, and the spindle motor 13f for rotationally driving the optical disc D is provided at the approximate center of the storage portion 12. The main body 13 and the cartridge pin 15 that protrudes from the main body 13 toward the inside of the storage portion 12 and is inserted into the insertion groove C1 of the disk cartridge C, and is regulated to a predetermined position where the spindle motor 13f can rotate the optical disk D. The main body 13 has a configuration in which a deformation restricting member 17 that protrudes outside the side wall 12b of the storage unit 12 and prevents deformation of the side wall 12b of the storage unit 12 is formed.
With this configuration, when a large vibration / impact is applied, a rotational moment acts on the disk cartridge C, and the corner portion Cc is displaced in a direction (X direction) perpendicular to the width direction of the opening 12a of the storage portion 12. In addition, the side wall 12b of the storage unit 12 can be prevented from being deformed.

Further, the deformation restricting member 17 is configured to protrude toward the opening 12a from the side wall 12b of the storage portion 12 in the attaching / detaching direction (Y direction).
With this configuration, when a large vibration / impact is applied, when a rotational moment acts on the disk cartridge C and the side end surface C5 hits the opening 12a side of the side wall 12b of the storage portion 12, the impact load is reduced. Although there is a high possibility of being applied multiple times, even in such a case, the side wall 12b can be effectively prevented from being plastically deformed or damaged.
Further, the position where the deformation restricting member 17 is formed is within a range in which the cartridge pin 15 is elastically deformed when the corner portion Cc of the disk cartridge C is displaced in a direction (X direction) perpendicular to the width direction of the opening 12 a of the storage portion 12. If it is set, the cartridge pin 15 can be prevented from being plastically deformed or broken from the base.

Further, the distance Gs between the deformation regulating member 17 and the side wall 12b of the storage unit 12 is configured such that the side wall 12b is not plastically deformed even if the side wall 12b of the storage unit 12 abuts against the deformation regulation member 17. .
With this configuration, even when the side wall 12b of the storage portion 12 is momentarily elastically deformed when subjected to large vibrations / impacts, since the plastic shape is not reached, the original shape is easily restored. Even after receiving such an impact or impact, the disc cartridge C is easily returned to a predetermined position, and not only can the rotation drive for normal recording / reproduction be continued, but also the smooth slideability of the disc cartridge C is ensured and detachable. The impact on work can be greatly reduced.
Further, by forming both the above-described transition regulating member 16 and the deformation regulating member 17, the disk cartridge C can be stored in the storage portion 12 in the attaching / detaching direction (Y direction) even when subjected to a large vibration or a drop impact. The disk cartridge C can be prevented from being displaced so as to protrude from the opening 12a, and also when the disk cartridge C is displaced in the rotational direction (θ direction) due to the rotational moment acting on the disk cartridge C, It can prevent effectively that the side wall 12b of the storage part 12 deform | transforms by a collision.

In particular, in the case of an impact of dropping while mounted on an electronic device, it is sufficiently expected that a large impact load is continuously applied in two directions positioned at right angles to each other because it collides with the floor surface a plurality of times. Therefore, forming the displacement restricting member 16 on the opening 12a side of the storage portion 12 and forming the deformation restricting member 17 on the outer side of the side wall 12b positioned in the direction perpendicular to the width direction of the opening 12a is the impact of the fall. It is a very effective configuration for greatly reducing the effects of

In the case of the first embodiment, for example, the total weight of the main body 13 of the disc type record carrier device 11 is about 25 g, and the outer dimensions of the main body 13 are a width of the main body of about 44 mm, a depth of about 43 mm, and a height. Set to about 9.5 mm, the weight of the disk cartridge C was set to 3.8 g, the height was set to 2.8 mm, the inner diameter of the insertion groove C1 was set to 1.71 mm, and the outer diameter of the cartridge pin 15 was set to 1.6 mm. In this case, when the gap Gc in the height direction between the upper surface C4 of the disk cartridge C and the upper wall 12c of the storage portion 12 is about 0.35 mm, the disk cartridge C when the disk cartridge C is restricted to a predetermined position. The height Hh (see FIG. 7) of the deformation restricting member 17 in the height direction (Z direction) with respect to the lower surface C3 is set in a range of about 1.5 to 2.5 mm. And more preferably set in a range of about 0.3 ~ 0.4 mm distance Gh in the width direction of the opening 12a from the wall 12b (X direction).

In the above description, the positional relationship between the displacement restricting member 16 and the deformation restricting member 17 with respect to the main body 13 is not limited to the first embodiment, and symmetry in the vertical and horizontal directions is necessary. However, the material may be set as appropriate in consideration of the material and dimensions of the members used therein, and the impact resistance and vibration resistance required for the electronic equipment on which the apparatus is mounted.

(Embodiment 2)
FIG. 10 is an exploded view of the electronic device according to the second embodiment of the present invention, and FIG. 11A is a cross-sectional view taken along the CC line after the electronic device shown in FIG. 10 is assembled. FIG. 11B is a sectional view taken along the arrow DD after the electronic device shown in FIG. 10 is assembled.
Here, the same reference numerals are used for the disc-type record carrier driving apparatus 11 described in the first embodiment, and the description overlapping therewith is omitted.

First, as shown in FIG. 10, the disc-type record carrier driving device 11 includes a vibration isolating portion 14f or a vibration isolating portion 14r protruding from each side surface. After the electronic device 100 (see FIGS. 11A and 11B) is mounted in a rectangular mounting space surrounded by the inner bottom surface 201a and the inner wall surface 201b of the lower case 201, the liquid crystal display 102 and the push button switch 103 are mounted. The upper case 101 provided with a fixing portion 101a and a fixing portion 101b (see FIGS. 11A and 11B) is overlapped on the lower portion.
As a result, as shown in FIG. 11 (a) or FIG. 11 (b), the lower case 201 extends from below to the lower surface of the vibration isolator 14f and the vibration isolator 14r provided in the disc type record carrier driving device 11. The inner bottom surface 201a (see FIG. 10) is in contact with the upper surfaces of the vibration isolating portion 14f and the vibration isolating portion 14r from above in the directions indicated by the broken arrows, respectively. Further, the inner wall surface 201b (see FIG. 10) of the lower case 201 is in contact with the left side surface of the vibration isolating portion 14f from the left in the direction indicated by the dashed line arrow, and the right side surface of the vibration isolating portion 14r is the right direction. To the inner wall surface 201b (see FIG. 10) of the lower case 201 in the direction indicated by the one-dot chain line arrow, and the other side surfaces of the vibration isolating portion 14f and the vibration isolating portion 14r are Inner wall 20 b (see FIG. 10) abuts in a direction indicated by a two-dot chain line arrow, whereby a predetermined amount is provided between the main body 13 (see FIG. 2) of the disk type record carrier driving device 11 and the inner surface of the electronic device 100. While securing the gap, the electronic device 100 can be fixed while securing a predetermined elastic force in all three directions of the vertical direction, the front-rear direction, and the left-right direction.

As a result, the shock absorption area, which is the contact area between the vibration isolator 14f and the vibration isolator 14r of the fixed portion 101a or the fixed portion 101b of the electronic device 100 and the disc type record carrier driving device 11, is increased, and the Since the entire surface of the vibration portion 14f and the vibration isolation portion 14r is in uniform contact with each other, improvement in impact resistance and vibration resistance can be realized.
In this case, the inner bottom surface 201a and the inner wall surface 201b of the lower case 201 constitute a fixing portion for the vibration isolating portion 14f or the vibration isolating portion 14r, although they are not referred to as fixing portions.

In a static state where there is no vibration or impact after the disc-type record carrier driving device 11 is mounted in a rectangular mounting space surrounded by the inner bottom surface 201a and the inner wall surface 201b of the lower case 201 of the electronic device 100. However, it is not always necessary to bring these fixed portions into contact with the three-direction contact surfaces of the vibration isolating portion 14f or the vibration isolating portion 14r. For example, in the case of the second embodiment, a maximum gap of about 0.3 mm may be provided between the fixed portion and the fixed portion.

Further, the height of the main body 13 (see FIG. 2) is added to the height of the vibration isolator 14f or the vibration isolator 14r so that the overall height of the apparatus does not increase. By bringing the fixing portion 101b of the electronic device 100 into contact with the surfaces of the vibration portion 14f and the vibration isolation portion 14r, the electronic device 100 can be easily reduced in thickness, and it is not necessary to use screws to fix the both. As a result, a more uniform fixing stress can be obtained over the entire contact surface without any local fixing stress acting, and the impact resistance of the mounted disc type record carrier device 11 despite the thinning of the electronic device 100. And vibration resistance can be improved, so higher reliability can be secured.

Furthermore, with this configuration, even a small, lightweight, and thin electronic device that is easily affected by vibrations and shocks can have a large transition such as the ejection of a disk cartridge of a disk-type record carrier driving device mounted therein. This prevents accidents such as damage to the components inside the electronic device, damage to the optical disk, or loss of optical disk attachment / detachment due to deformation of the storage unit, and the effects of vibration and shock are greatly reduced, which is higher. A reliable electronic device can be provided.

Although the present invention has been described in detail and with reference to specific embodiments, it will be apparent to those skilled in the art that various changes and modifications can be made without departing from the spirit and scope of the invention.

The present invention is built in an electronic device including a mobile communication system such as a mobile system such as a personal media player, a mobile Internet device, a mobile phone, a portable videophone terminal, a PDA, and a micro PC, or an in-vehicle navigator system. It can be applied to a disk type record carrier driving device.
