Description

  The present invention relates to a detachable recording medium socket device, and more particularly to a socket device effective when a plurality of hard disks, floppy (registered trademark) disks, and memory cards are mounted as recording media.

  2. Description of the Related Art Conventionally, semiconductor recording media, magnetic recording media, magneto-optical storage media, etc. that retain information therein are used as recording media that are widely used in devices such as personal computers (PCs). In addition, digital data to be recorded is not limited to text data such as characters, but has been recorded and accumulated for large-capacity moving images such as still images and audio data from digital cameras and digital video. .

  Video tape recorders are widely used as devices for recording and storing television broadcasts, etc., but video tape recorders using video tape as recording media are widely used. The recording system used has appeared, and further, a device that has a built-in hard disk device having a recording capacity of several tens of gigabytes and capable of recording a broadcast for a relatively long time has appeared.

  As described above, when the capacity of data to be recorded increases, if the recording medium is built in and fixed in the device and cannot be easily exchanged, the capacity becomes insufficient and new data cannot be recorded additionally. It was. For this reason, in order to increase the recording capacity, a method has been adopted in which the number of mounted storage devices is increased simultaneously with efforts to improve the recording density of the medium itself.

  In response to such demands, a proposal has been made for a hard disk mounting device that allows a plurality of hard disks to be mounted and driven, while considering that a hard disk with a full capacity can be replaced with another new hard disk. For example, Japanese Patent Application Laid-Open No. 6-309859 proposes a hard disk mounting apparatus in which thin box-shaped hard disks are mounted in multiple stages in the thickness direction and are made detachable from the front side of the apparatus as a device main body storage device for hard disks.

  This hard disk mounting apparatus is set with a metal storage case of a predetermined size so that a predetermined number of hard disks can be incorporated therein. Shelf-shaped guide rails are provided on the left and right sides of the inner surface of the storage case. A hard disk is placed on the guide rail from the front and slid rearward, and the connector on the hard disk side is connected to the connector for connection provided on the back. Mount to the storage position to be joined. After that, the mounting opening is closed to prevent the hard disk from popping out, and the panel, which is a plate-like component having a pressing function, is fixed to the storage case with a mounting screw.

  However, the above-mentioned hard disk mounting device requires a dedicated mounting device depending on the number of hard disks mounted therein, and for example, it is necessary to prepare a completely different mounting device in the case of mounting two units and in the case of three units, It is not possible to easily add more hard disks than the predetermined number of attachment devices.

  In addition, when the capacity of the hard disk already inserted is full, or when the hard disk needs to be replaced due to failure, a tool such as a screwdriver is prepared and screwed to the front of the mounting device. The troublesome work of removing the panel and pulling out the hard disk along the rails is necessary.

  In addition, when multiple hard disks are installed and the space between adjacent hard disks is set narrow to reduce the installation space, fingers cannot be caught during removal. There is also a disadvantage that the target hard disk cannot be removed without first removing the hard disk that is located on the outermost side and is easy to remove.

  Therefore, although the installation space becomes large, either a clearance should be given priority to the detachability, or the other way around, either one has to be sacrificed.

  Therefore, the present invention has been made to provide a socket device for a recording medium such as a hard disk which is considered to be able to be removed and solves the above-mentioned problems, and a thin configuration in which a plurality of sockets are closely mounted in a stacked manner is possible.

(Example)
Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 2 is an external view showing an electronic device 30 such as a PC (Personal Computer) or a video deck in which the socket device 10 of the present invention is mounted. In the figure, four socket devices 10 are mounted inside the electronic device 30 in a stacked state, and a maximum of four hard disks 20 that can be attached to and detached from the socket device 10 can be inserted. An entrance 11 is provided on the front surface 31 of the device. Of the four socket devices 10, 10 ′, 10 ″, 0 ′ ″, the leftmost mounted socket 10 indicates that the hard disk 20 is not mounted, and the center two 10 ′, 10 ′. 'Indicates a state in which the hard disk 20 is completely inserted and usable, and the rightmost socket device 10''' indicates a state in which the hard disk 20 is removable from the socket device 10 or a state in which it is inserted.

  FIG. 10 shows an external view of the hard disk 20. The outside of the hard disk 20 is covered with a substantially flat rectangular housing, and a hard disk device surrounded by a buffer material is mounted inside. This hard disk device is provided with a connection connector 202 on one side of the casing, which serves as an interface for recording and accumulating electronic data from the outside, reading out the recorded data, and outputting the data to the outside. Further, a guide groove 201 that fits with a guide rail provided in the socket device 10 to be described later is provided on two opposing side surfaces so that the socket device 10 can be easily and reliably inserted into the socket device 10.

  When the hard disk is not installed, the insertion slot 11 is covered with the door 12 to prevent the entry of dust and dirt into the device.

  The structure of the socket device 10 having such a relationship with the device will be described below. FIG. 1 is a perspective view of the external appearance of the front surface taken out independently for explaining the configuration of the socket device 10 mounted on the electronic device 30 of FIG. 2, and FIG. 3 is a diagram further rotating FIG. FIG.

  In FIG. 1, the hard disk insertion slot 11 is covered with the door 12 provided at the right end of the figure as described above, and when the hard disk is inserted, the door 12 is pushed by the tip, and the rotation shafts provided at both ends in the longitudinal direction. It rotates about 121 and 122, is pushed by the insertion front end surface of the hard disk, and is folded and accommodated inside. The door 12 is urged by a spring or the like in a direction that always closes the opening. When the hard disk is removed from the socket 10, the door 12 is restored to the original closed state by the spring force. The rotating shafts 121 and 122 are held by left and right guide arms 131 and 132 arranged in parallel to each other, and a space in which a hard disk is mounted is formed in an inner space 133 of the guide arm portion.

  Reference numeral 40 denotes a push button for ejecting the hard disk inserted in the socket device 10 with a finger or the like, and an eject mechanism provided in the socket will be described later. Further, the entire structure denoted by 50 is an auto-eject mechanism that operates a motor 502 that is a drive source provided on the chassis 501 to electrically eject the hard disk, and details thereof will be described later.

  A connector 14 is disposed at a position opposite to the insertion slot 11, and a plurality of connection connections are formed on the front surface of the connector 14 so as to be fitted with a connector (202 in FIG. 10) provided on the front surface in the insertion direction of the hard disk. Terminal 141 is disposed. Both ends of the connector are formed at right angles to the arrangement of the terminals 141 and guide arm holding portions 142 and 143 extending in the direction of the door 12 are formed integrally with the frame of the connector 14, and left and right guide arms are formed on the outer surface thereof. 131 and 132 are fixed and parallel to each other is ensured. Further, when the guide arms 131 and 132 are attached to the left and right guide arm holding portions 142 and 143 of the connector 14, the bottom surfaces of these three members form a substantially single plane. A metal plate-like bottom plate 15 is fixed so as to cover the common bottom surface across these three members, and maintains the overall strength. The upper surfaces 134 and 135 of the left and right guide arms 131 and 132 constitute surfaces that are substantially parallel to the surface including the bottom plate 15.

  A plurality of terminals 144 for external connection are provided on the back portion of the connector 14 facing the terminal portion 141, and are fixed by soldering with pads provided on one side of the printed circuit board 145. Further, a pin terminal connector 146 and a socket type connector 147 are provided on the opposite surface of the printed board, and serve as an interface connector with the outside for electrical connection.

  On the inner surface 136 of the right guide arm 131 that surrounds the space 133 for mounting the hard disk, the guide arm of the connector 14 is projected from the position where the protruding guide rail 138 protrudes from the insertion slot 11 at a position that protrudes toward the space 133 and faces each other. It is provided toward the holding parts 142 and 143. Further, the guide rail 138 is formed so as to extend to the guide rail 146 provided on the inner side surface 144 facing the space 133 of the guide arm holding portion 142. Similarly, on the inner side facing the space 133 of the left guide arm 132 and the guide arm holding portion 143, a similar guide rail is formed at a position facing the guide rails 138 and 146.

  These guide rails 138, 146 and the opposite positions thereof are fitted with guides 201 formed on both sides of the thickness surface of the hard disk when the hard disk 20 of FIGS. 1 is joined to the connector 202 shown in FIG. 1 and the connection connector 202 provided at the leading end of the hard disk 20 in the insertion direction, to form an electrical connection. In particular, immediately before the connectors are joined, the guide groove 201 is guided by the guide rail formed integrally with the frame of the connector 14, so that unnecessary stress is not applied to each other's connector terminals and stable connection is maintained. Be drunk.

  The guide groove 201 and the guide rails 138 and 146 and the guide grooves and guide rails provided at the opposite positions are shifted from the center position in the thickness direction, so that they cannot be inserted when the upper surface and the lower surface of the hard disk are inserted incorrectly. It has been taken into account.

  Further, the guide groove 201 is not formed up to the rear end of the hard disk 20 in the insertion direction, and serves to prevent erroneous insertion at the front and rear ends in the insertion direction (see FIG. 10).

  In FIG. 3 showing the back side of the socket device 10, as described above, the socket back surface is almost entirely covered with a thin plate-like bottom plate 15, and a metal plate is used for the purpose of ensuring the overall strength. When the hard disk is inserted into the socket device 10 and is driven, it also functions as a good heat conductor that releases heat generated from the built-in motor and electronic circuit to the outside from the socket 10. Furthermore, it is possible to provide a function of grounding the potential of the bottom plate 10 to the ground level and blocking both electric noise generated from the inside during the hard disk operation and propagating to a nearby electronic circuit, or conversely, noise from the outside.

  Two positioning pins 151 and 151 protrude from the bottom plate 15 to the outside of the socket device 10 in the thickness direction. The positioning pin 151 is fitted into two positioning holes 139 and 139 which are opened at the same position facing the positioning pins 151 and 151 on the upper surface of the guide arms 131 and 132 shown in FIG. When the other socket devices 10 are mounted in the same position in the thickness direction, they are used for positioning each other. Therefore, one of the two positioning holes 139 may be a long oval hole on a line connecting both hole centers.

  FIG. 4 and FIG. 5 show the four socket devices 10, 10 ′, 10 ″, 10 ′ ″ viewed from the front side and the back side in a state where they are stacked in the same direction. 139 and positioning pins 151, 151.

  Further, FIG. 6 is used to show how the four sockets are positioned and fixed to each other. FIG. 6A is a plan view showing a state in which four socket devices 10 are stacked. FIG. 6B is a cross-sectional view cut from the portion indicated by AA in FIG. 6A, and the fixing holes in which the left and right guide arms 131 and 132 are formed in a hexagonal concave shape. A plurality of sockets are fixed to each other using the through holes 152, 152. A state in which the screw 60 and the nut 61 inserted into the through hole 152 are fixed by being fixed after being positioned by the method described later. The screw 60 penetrates through holes provided in four sockets and is screwed to a hexagon nut 61 inserted into a hexagonal concave portion for preventing rotation from the opposite side.

  Further, FIG. 6C shows a cross section of FIG. 6A in the socket stacked state cut from the portion indicated by B-B, and the positioning pin 151 of the socket device 10 located on the leftmost side is the socket device 10 on the right side. The positioning holes 139 are fitted to each other to regulate their positions. Further, the positioning pin 151 of the socket device 10 ′ is further fitted into the positioning hole 139 of the socket device 10 ″ on the right side so as to restrict the positions thereof. In this way, the adjacent sockets are sequentially regulated in the same position and in the same direction, so that all four socket devices are constrained to a fixed positional relationship.

  Thus, since all the socket devices 10 are provided with at least one pair of positioning pins 151 and positioning holes 139 and are provided with fixing through holes 152, the four shown in this example are stacked. This is not limited to the case, and it can be easily performed when two or more arbitrary numbers of socket devices are stacked and integrally mounted.

  2, when these stacked sockets are mounted inside the electronic device 30 or the like, the interval corresponding to the thickness after stacking, that is, the cross-sectional view of FIG. 6B or 6C. The mounting chassis is set on the left and right sides so that the thickness from the left side surface to the right side surface is included, and a protrusion corresponding to the positioning pin is provided on the left side surface, and a hole corresponding to the positioning hole is provided on the right side surface. Furthermore, a screw fixing fixing hole is provided at a position corresponding to the through hole 152 and is fixed with a penetrating screw using this hole.

  Alternatively, the mounting may be performed using mounting bosses 131a and 132a each having a pre-installed self-tapping screw pilot hole. These mounting bosses are formed so as to project integrally from the side surfaces of the left and right guide arms 131 and 132 made of a synthetic resin material.

  Since the auto eject mechanism 50 is configured within the thickness of the socket device 10, it is set so that even if the socket device is stacked as shown in FIGS. 4 and 5, the adjacent devices can be stacked without competition. .

  As can be seen from these cross-sectional structural views, since the upper surfaces of the guide arms 131 and 132 and the bottom plate 15 are in close contact with each other, a thin mounting suitable for housing in a limited pace can be achieved.

  Further, a description will be given of how to deal with vibration and heat generated when a plurality of socket devices 10 are closely mounted and a hard disk is inserted and operated.

  The hard disk is written and read by a head that rotates at high speed inside the disk and moves close to the magnetic material on the disk surface. For this reason, vibration generated when the disk rotates may be transmitted from the adjacent socket to the mounting portion of the device, and may be emitted to the outside of the device as annoying noise. When a plurality of inserted hard disks are simultaneously operated, it is emitted as a larger vibration sound. FIGS. 7A and 7B are cross-sectional views taken from positions AA and BB in FIG. 6A, respectively, and vibration is caused by interposing a plate-like intermediate body 70 between the socket devices. Is absorbed. The material of the intermediate body 70 is an elastic member such as rubber that absorbs vibration, and has a suitable hardness and thickness depending on the frequency and amplitude. When it is necessary that the thickness of the intermediate inclusion 70 be thicker than the height of the positioning boss 151, a hole for fitting the positioning boss 151 into the intermediate inclusion 70 and a protrusion fitting with the positioning hole 139 on the back surface of the outer hole are provided. Provide.

  Further, in order to prevent the heat generated from the disk rotation motor built in the hard disk or the built-in electric element from accumulating, if the intermediate body 70 is made of a material having good thermal conductivity, the magnetic property of the disk surface due to high temperature can be increased. The risk of body deterioration can be reduced. Examples of the material of the intermediate inclusion 70 having this function include aluminum, copper, and high thermal conductivity graphite.

  Moreover, soft steel, stainless steel, galvanized steel plate and the like having excellent radiation heat dissipation characteristics are good on the outermost surface of the unit of the socket device, and the characteristics are further improved by applying a matte black coating on the surface.

  Further, in order to suppress both vibration and heat generation, an intermediate inclusion 70 having a composite function in which the above-described materials are laminated into a single plate shape may be used.

  Next, the hard disk ejection mechanism of the socket apparatus 10 will be described with reference to FIGS.

  FIG. 8 is a perspective view showing a state in which the push button 40 is not operated, that is, a hard disk is not inserted or is completely inserted (hard disk is not shown). The push button 40 is fixed to a narrow rectangular lever 41. The lever 41 is guided in the guide arm 132 so as to be movable only in the thrust direction, and is always urged to the right in the drawing by a spring or the like. A tip 411 of the lever 41 extends to the vicinity of the connector 14 and protrudes upward, and is in contact with the end 421 of the rotating plate 42.

  An auto-eject operating lever 412 that is bent outward at a right angle in the horizontal direction is formed near the tip 411, and a caulking shaft is fixed to the tip. A roller 413 is rotatably attached to the caulking shaft and is prevented from coming off by a retaining ring.

  The end 421 of the rotating plate 42 is held in a recess between the base of the operating lever 412 and the protrusion of the lever tip 411. The rotating plate 42 has a hollow protruding shaft processed by burring or the like so as to rotate about the rotation center 422 on the upper surface of the bottom plate 15 and protrudes downward, and is fitted to a hole formed in the bottom plate 15 so as to be rotatable. Locked.

  A slide plate 43 faces the upper surface of the rotating plate 42. Both ends of the rotating plate 42 are guided by the grooves of the left and right guide arms 131 and 132 so that the left and right can be translated in the plane direction (see FIG. 8 shows a partially broken view). A part of the slide plate 43 is provided with a folded portion 431 which is folded back with the plate thickness as a gap so as to sandwich the operating portion 423 of the rotary plate 42, and the rotary plate 42 is clockwise with respect to the rotation center 422. , The folding portion 431 is pressed by the operating portion 423, and the slide plate 43 slides in the right direction in the figure. At the left end of the slide plate 43, there are provided a pair of ejection operation parts 432 and 432 extending to the notches provided on both sides of the connector 14 and bent upward, and the hard disk is ejected by the ejection operation parts. become.

  The ejected state of the socket device 10 is shown in FIG. By manually operating the push button 40 provided on the front surface of the socket device by manual operation, the lever 41 is moved in the left direction in the figure, the rotating plate 42 is rotated clockwise around the rotation center 422, and the slide plate 43 is further moved. It slides to the right and is ejected to the outside by the eject actuating section 432 so that the hard disk can be taken out from the socket device.

  If the moving amount of the slide plate 43 is set to about 20 to 30 mm, the center of gravity of the hard disk remains inside, so that it does not jump out of the electronic device 30 shown in FIG. 2, and the protruding portion can be easily taken out from the device. .

  When the operation of the push button 40 is stopped in this state, the lever returns to the position shown in FIG. 8 by the return spring (not shown), and the rotary plate 42 returns to the position shown in FIG. Stops at this position because does not work. However, when the hard disk is inserted again, the eject operation unit 432 is pushed by the tip of the hard disk and carried to the position shown in FIG.

  Further, an auto eject mechanism which is another eject mechanism will be described.

  8 indicates an auto-eject mechanism, and is provided on a small chassis 501 attached to the side surface of the guide guide arm 132. A DC motor 502 is fixed to the chassis 501 and used as a power source. By applying a DC voltage to the DC motor 502, the rotating shaft rotates and the worm 503 press-fitted into the shaft rotates. Reference numeral 504 denotes a worm wheel gear 505 in which a lower wheel engages with the above-mentioned worm 503, and a worm wheel gear wheel 506 formed with a small gear 506, and these two elements are synthetic resin materials. And is used in the middle to transmit the rotation of the motor 502 to the next large gear 508 to reduce the rotational speed and increase the torque.

  A cam gear 507 has a large gear 508 that meshes with the small gear 506 in the lower stage, and a cam 509 formed as an integral part in the upper stage. Similarly, the cam gear 509 is inserted into a shaft crimped to the chassis 501 and is rotatably held. Yes. The cam 509 is set to rotate clockwise about the rotation axis when the DC motor 502 is driven. The cam surface of the cam 509 with which the work object comes into contact has a shape that gradually moves away from the cam rotation center as it rotates, and returns to the nearest closest position once in one rotation. In the initial position of FIG. 8, that is, the position where the hard disk is completely inserted (the hard disk is not shown), the roller 413 attached to the auto-eject operation lever 412 of the lever 41 which is the work object and the cam rotation shaft are closest. Touching in position.

  When the motor 502 is energized and rotated from this position, the cam 509 is rotated clockwise by the driving force transmission mechanism described above, and the roller 413 in contact with the cam surface is displaced away from the shaft. The lever 41 moves to the left in the figure as when operated.

  FIG. 98 shows a state in which the rotation of the cam 509 further proceeds and the roller 413 is displaced to the position farthest from the cam 509 rotation axis. At this position, the eject operating portions 432 and 432 of the slide plate 43 are located closest to the insertion slot 11 and the hard disk is ejected by this displacement stroke.

  Since the auto-eject mechanism 50 is configured to fit within a region sandwiched between the extended surfaces of the upper and lower guide arms indicated by reference numerals 134 and 135 on the upper surface of the socket device in FIG. The adjacent auto-eject mechanisms 50 do not compete with each other even if the positioning pins 151 and the positioning holes 139 are fitted and mounted in close contact with each other.

  The ejecting mechanism of the socket 10 is a so-called first manual ejecting mechanism that operates the lever 41 by operating a push button 40 provided on the entire surface of the socket device in the hard disk insertion direction, and makes the hard disk removable from the socket device. Both the auto-eject mechanisms, which are the second eject mechanisms described above, can be selectively used without contradiction. For example, the auto-eject mechanism can be operated only when the hard disk is not in read / write operation. If the drive system that controls the operation stops operating due to some inconvenience, the push button 40 is operated as an emergency eject. And take out the hard disk. In that case, the push button 40 is intentionally made small so that it is difficult to operate with a finger, or may be arranged at a position slightly retracted from the front surface of the socket device.
