The lid 220 is pivotally supported by a pivotal support (not shown) provided on the rib 112 in a state of being a rotation center axis in the width direction in the vicinity of the end on the prismatic portion side of the peripheral edge 222. A shaft member is provided. The lid body 220 is attached to the housing 110 so as to rotate in a state in which the semicircular side is inserted into the rib 112 so that the semicircular side becomes a rotational end, and to open and close the opening 111.

  Further, the lid 220 is positioned on the rotation base end side which is the shaft member side on the surface on which the peripheral edge portion 222 of the lid plate portion 221 protrudes, and the position where the lid 220 is inserted into the slit of the housing 110 by the rotation. A locking pin portion 223 as a locking portion that makes a pair is projected. These locking pin portions 223 are formed in a columnar shape that is convex so as to protrude in the rotation direction in which the lid body 220 is rotated in the closed state, and the distal end portion is curved in at least the rotation direction of the lid body 220. Is formed.

  As shown in FIG. 1, the cover body 230 is made of, for example, a synthetic resin and includes a rectangular plate-like cross-linking plate portion 231. At one edge in the longitudinal direction of the bridge plate portion 231, a protective portion 231 </ b> A that protrudes in a tongue shape toward the side is provided in series. Further, at both ends in the longitudinal direction of the bridging plate portion 231, flange portions 232 that are stepped on one side and project in a hook shape in the longitudinal direction are provided. Further, the flange portion 232 is a guide that is fitted into and engaged with the slit of the housing 110 in a bottomed cylindrical shape on the surface of the flange portion 232 that is stepped with respect to the bridging plate portion 231. A portion 233 is provided. The guide portion 233 is an engagement recess 234 as an engagement portion that opens toward the side on the inner peripheral side from which the bridging plate portion 231 protrudes with respect to the flange portion 232.

As shown in FIGS. 2 to 4, the cover 230 is disposed in a state where the shallow side where the inclined surface 234 </ b> A of the engagement recess 234 is inclined is positioned on the rotation base end side of the lid 220. Further, an elastic member 235 such as a coil spring is attached to the cover body 230 between the end surface of the guide portion 233 and the base portion 211 of the main body portion 210. Then, the cover 230 receives the pickup lens 213A of the information processing unit 213 in the standby position in a state in which a tensile force that is a restoring force due to elastic deformation of the elastic member 235 is applied and is always pulled toward the turntable 212B. It is located in the state covered with 231A. Further, when the pressing force that the locking pin portion 223 of the lid body 220 engages in the engagement recess 234 and slides on the inclined surface 234A is applied, the cover body 230 is elastically deformed to pull the elastic member 235. The state is moved away from the turntable 212B, and the state where the protection lens 213A covers the pickup lens 213A is released, that is, the pickup lens 213A is exposed.

  In order to detect that the lid 220 has been opened or to detect that the cover 230 is located at a position that covers the pickup lens 213A, for example, a detection switch (not shown) is provided on the pedestal 211 or the like. Based on the detection signal output from the detection switch, the control unit of the main body unit 210 may perform control to move the information processing unit 213. Further, the control unit may recognize that the lid 220 is opened based on an operation signal indicating that the lid 220 is opened by an input operation of the operation unit, and the information processing unit 213 may be moved.

[Operation of imaging device]
Next, the operation of the imaging apparatus 100 will be described.

  First, the user operates the operation unit to rotate the lid body 220 to open the opening 111 on one side surface of the housing 110 as shown in FIG. The rotation of opening the lid 220 releases the state where the locking pin portion 223 of the lid 220 is engaged with the engagement recess 234 of the cover 230 and the movement is restricted, as shown in FIGS. 1 and 2. In addition, the cover 230 is moved to the turntable 212B side by the tensile force of the elastic member 235, and the protection unit 231A is in a state of covering the pickup lens 213A of the information processing unit 213. In this state, the user pivotally supports the optical disc 1 on the turntable 212B. When the optical disc 1 is mounted, the outer edge portion of the optical disc 1 is placed on the protective portion 231A and brought into contact with the one side edge of the bridging plate portion 231, and the turntable 212B is inserted into the hole portion 1A. It is easy to put it on. Since the pickup lens 213A is covered with the protection unit 231A at the time of mounting, the user's hand and the optical disc 1 do not contact the information processing unit 213, and the information processing unit 213 is protected.

  Then, when the user performs an operation of rotating and closing the lid 220 in a state where the opening 111 is closed, the locking pin portion 223 of the lid 220 is inserted into the engagement recess 234 of the cover 230. It becomes a state to do. Further, when the user rotates the lid body 220 in the closed state, the distal end portion of the locking pin portion 223 comes into contact with the inclined surface 234A of the engaging recess 234 as shown in FIG. Furthermore, the pressing force that presses the lid 220 by the user against the housing 110 acts, so that the tip of the locking pin portion 223 slides on the inclined surface 234A by the component force of the pressing force, and the covering 230 is The elastic member 235 is elastically deformed so as to be pulled, and is moved away from the turntable 212B. When the lid 220 is closed, as shown in FIG. 4, the engaging pin portion 223 is engaged with a state where it is extended to a deep position of the inclined surface 234A of the engaging recess 234, and the pickup lens 213A is opposed to the position. Then, the protection portion 231A is retracted and the covering state is released, and the pickup lens 213A is exposed. Furthermore, the cover 230 is separated from the periphery of the optical disc 1 that is pivotally supported by the turntable 212B. As a result, information processing of the optical disc 1 becomes possible. In this state, the image data and sound data generated are recorded on the optical disc 1 by operating the operation unit to perform imaging and recording. Further, the image data and sound data recorded on the optical disc 1 are appropriately reproduced on the display unit and the sound generation unit by a predetermined input operation of the operation unit.

  When the lid 220 is accidentally opened while the optical disc 1 is rotated by the disc rotation driving unit 212 for information processing or the like, as described above, the locking pin portion 223 of the lid 220 is used. The engagement state of the cover 230 with the engagement recess 234 is released. Accordingly, the cover 230 is moved to the turntable 212B side by the tensile force of the elastic member 235, and the cover 230 comes into contact with the periphery of the optical disc 1. For this reason, the cover 230 acts as a brake for the rotating optical disk 1 and immediately stops the rotation of the optical disk 1, so that the rotation is already stopped when the lid 220 is opened and the user touches the optical disk 1. Inconvenience does not occur.

[Operational effects of the imaging device]
As described above, in the above-described embodiment, the turntable 212B that faces the opening 111 of the housing 110 and rotatably holds the optical disk 1 and the optical disk 1 that faces the opening 111 and is held on the turntable 212B. A lid body 220 that closes the opening 111 so as to be openable and closable is provided in a housing 110 in which a main body 210 including an information processing unit 213 that performs information processing is disposed. The lid 220 covers the pickup lens 213A of the information processing unit 213 with the opening 111 opened, and covers the pickup lens 213A when the lid 220 closes the opening 111. A cover 230 is provided that is released from the state and is moved to a position away from the outer periphery of the optical disk 1 that is pivotally supported by the turntable 212B. For this reason, even if the lid 220 is opened when the optical disk 1 is attached / detached, and the information processing unit 213 is exposed, the cover 230 that moves without touching the user's hand or the optical disk 1 is provided. The information processing unit 213 can be reliably protected. Then, in a configuration in which the turntable 212B having a self-chucking function is provided and the processing space of the optical disc 1 is opened and closed by the lid 220, such as an imaging device or a portable disc drive, the user's hand when the optical disc 1 is attached or detached. This is particularly effective because the optical disc 1 itself and the optical disc 1 are easily touched.

  Then, a locking pin portion 223 is provided in the lid body 220, and an engagement recess 234 in which the locking pin portion 223 is engaged and disengaged according to opening and closing of the lid body 220 is provided in the cover body 230. The locking pin portion 223 and the engagement recess 234 cover the information processing unit 213 by the engagement pin portion 223 engaging with the engagement recess 234 when the lid 220 is closed by closing the opening 111. It is configured to be moved from the position. Therefore, a configuration in which the information processing unit 213 is always covered with the elastic member 235 or the like when the lid 220 is opened, and the cover 230 is moved when the lid 220 is closed can be easily obtained. With this configuration, it is possible to easily obtain a state in which the information processing unit 213 is reliably protected.

  Further, an elastic member 235 is provided as a configuration for moving the cover body 230 when the cover body 230 always covers the information processing unit 213 and the lid body 220 is closed. For this reason, the structure which can protect the information processing part 213 reliably with a simple structure is easily obtained. Therefore, an increase in the size of the disk drive unit 200 is suppressed, and an electric device having other functions such as the imaging device 100 can be easily provided while preventing an increase in size.

  Further, the locking pin portion 223 of the lid body 220 is formed in a column shape projecting in the turning direction in which the lid body 220 is rotated in the closed state, and the locking pin portion 223 can be engaged and disengaged. The engaging recess 234 of the cover body 230 is formed in a concave shape having an inclined surface for moving the cover body 230 by sliding the tip of the 223. For this reason, the structure which moves the cover body 230 to the state which covers the information processing part 213 by the opening and closing of the cover body 220, and the state which cancels | releases a cover by simple structure is obtained.

  Further, the cover body 230 is in contact with the outer peripheral edge of the optical disc 1 held on the turntable 212B with the lid body 220 opened with the opening 111 open. For this reason, even if the lid 220 is accidentally opened, the rotation of the optical disc 1 is immediately stopped. Since the lid 220 is opened and the user can touch the optical disc 1, the rotation has already stopped. In addition, it is possible to prevent inconveniences such as damage to the optical disk 1 and the disk rotation driving unit 212 and discomfort to the user due to the rotating optical disk 1, and the optical disk 1 can be immediately replaced, so that convenience can be improved.

  In the state where the lid 220 is opened, the control unit of the main body unit 210 controls the information processing unit 213 to be positioned at the standby position farthest from the turntable 212B, and the information processing unit 213 at the standby position is controlled. A cover 230 is disposed so as to cover the pickup lens 213A. For this reason, it is not necessary to cover the entire moving range of the information processing unit 213 to which the cover 230 moves, the size can be reduced, the moving distance of the cover 230 can be set to a minimum, and the size can be easily reduced.

  In addition, since the cover 230 covers the pickup lens 213A of the information processing unit 213, the information processing unit 213 can be protected with a simple configuration in which the tongue-shaped protection unit 231A is provided, and the configuration can be simplified or downsized. Can be easily obtained, and the manufacturability of the cover 230 can be improved. In particular, since the optical pickup pickup lens 213A is easily protected from being easily damaged by contact with the user's hand or the optical disc 1, the information processing unit 213 is efficiently configured with a minimum configuration. Protection. Further, since the structure covers the pickup lens 213A, inconveniences such as adhesion of dust can be prevented and good information processing can be obtained. Since the tongue-shaped protection portion 231A protrudes from one side and covers the information processing portion 213, the cover 230 is in contact with the outer peripheral edge of the optical disc 1 pivotally supported by the turntable 212B. When the optical disk 1 is mounted, the optical disk 1 can be mounted easily by placing it on the protective portion 231A so as to come into contact with one side surface of the cover 230.

  Further, since the convex locking pin portion 223 is provided on the lid 220 and the engaging recess 234 is provided on the cover 230 disposed on the main body 210 side, the lid 220 can be reduced in size without increasing in size. Easy to obtain.

[Modification of Embodiment]
Note that the present invention is not limited to the above-described embodiment, and includes the following modifications as long as the object of the present invention can be achieved.

  That is, although the disk drive unit 200 provided in the imaging apparatus 100 is illustrated as the drive apparatus of the present invention, not only the imaging apparatus 100 but also a portable drive apparatus, a drive apparatus for a recording / playback apparatus, a broadcast reception such as a television or a radio. The present invention can be applied as various drive devices such as a drive device provided in a machine, a drive device of an acoustic device, or a single device or a composite form with other electric devices. In addition, the configuration in which both the reading process and the recording process are performed has been described, but the configuration may be such that only the reading process or the information processing only in the recording process is performed. Furthermore, although the optical disk 1 using light has been described as a recording medium for information processing, various methods such as a configuration in which a magnetic head serving as an information processing unit is covered for a magnetic disk, for example, can be used. The present invention is not limited to this and can be applied to various types of disk-shaped recording media such as magneto-optical disks and record disks.

  And although it was set as the structure opened and closed by rotation as the cover body 220, it is good also as a structure opened and closed by slide movement, for example. As such a configuration, for example, a locking portion protruding in a direction intersecting with the moving direction is brought into contact with one side of the cover body 230 and moved by the locking portion corresponding to the movement of the lid body 220. The structure etc. to make can be illustrated.

  Moreover, it is good also as a structure by which engagement / disengagement is reversed, such as providing the engagement recessed part 234 in the cover body 220, and providing the latching pin part 223 in the cover body 230. FIG. Furthermore, the configuration in which the cover body 230 is moved in accordance with the opening and closing of the lid body 220 is not limited to the configuration of the locking pin portion 223 and the engagement recess portion 234, and for example, the rotation base ends of the cover body 230 and the lid body 220. The cover body 230 is moved to the turntable 212B side so as to be pushed out through the connection member when the lid body 220 is opened, and the information processing section 213 is covered. Any structure can be used, such as moving the cover 230 so that the cover member 230 is pulled by the connecting member when the cover is closed. Further, as a configuration for moving the cover body 230 in accordance with the rotation of the lid body 220, a mechanical configuration by engaging / disengaging the locking pin portion 223 and the engaging recess portion 234 has been exemplified. It is also possible to employ electrical control such as detecting the above and moving the cover 230 with a driving means such as a motor.

  And although it was set as the structure which covers the pick-up lens 213A of the information processing part 213, the bridge | crosslinking board part 231 and the protection part 231A are provided in the state which covers the substantially whole information processing part 213, for example, as shown in FIG. The position facing the pickup lens 213A may be cut out approximately in the middle of the protective portion 231A protruding so as to cover the lens. Even in the configuration as shown in FIG. 5, it is possible to prevent the user's finger or the optical disc 1 from contacting the pickup lens 213A. Since the pickup lens 213A is exposed, the pickup lens 213A can be used for control of, for example, emitting light and detecting the presence or absence of the optical disc 1 with the optical pickup, thereby improving versatility. Furthermore, the area where the protective part 231A is joined to the bridging plate part 231 increases, and damage to the protective part 231A can be prevented.

  In addition, the elastic member 235 has been described. However, the elastic member 235 is not limited to a configuration in which a tensile force is applied, and may be disposed so as to apply a pressing force, such as rubber or a leaf spring. An elastic member can be used. Furthermore, the elastic member 235 may not be provided in the configuration in which the lid body 220 and the cover body 230 described above are connected.

  In the above description, the information processing unit 213 is covered with the cover 230 and is in contact with the outer peripheral edge of the optical disc 1. However, the cover 230 may be formed so as not to always contact the outer peripheral edge of the optical disc 1.

  In addition, the specific structure for carrying out the present invention can be appropriately changed to another structure or the like as long as the object of the present invention can be achieved.
