Then, the lid 220 is attached to the housing 110 so as to rotate so as to be fitted into the rib 112 so that the semicircular side becomes a rotational end, and to open and close the opening 111.

Further, as shown in FIG. 1 and FIGS. 3 to 5, the temporary placement piece 113 can be inserted into the lid 220 at a position corresponding to the temporary placement piece 113 of the peripheral portion 222. A concave notch 223 is provided. Further, the lid 220 is positioned at the approximate center of the semicircular portion of the peripheral portion 222 and protrudes in a tongue shape toward the side from which the peripheral portion 222 protrudes. A locking piece 224 is provided as a possible locking part. The locking piece portion 224 is provided with a locking pin portion 224A that protrudes in a substantially cylindrical shape at the distal end portion of the surface of the lid body 220 facing the rotation base end side. Further, the lid 220 has a diameter dimension that allows the cylindrical portion 212A1 of the turntable 212A to be fitted to the inner peripheral side with the locking claw portion 212A3 not in contact with the center of the semicircular portion of the lid plate portion 221. The pressing part 225 protruding in a substantially cylindrical shape Is provided. As will be described in detail later, the lid 220 rotates the locking piece 224 so that it is disengaged from the engagement / disengagement recess 114 while the locking piece 224 is disengaged by the movement restricting portion 230. An urging member is provided. As the biasing member, an elastic member such as a coil spring, a leaf spring, or rubber can be used, and a configuration in which the lid 220 is rotated by driving a motor or the like can be applied.

[0017] The movement restricting section 230 detects a movement restricting cam 231 as shown in FIGS. 3 to 5, a movement restricting drive section (not shown) that moves the movement restricting cam, and that the movement restricting cam is moved. And a detection switch. The movement restricting cam 231 is made of, for example, a metal plate or a synthetic resin plate, is formed in a longitudinal plate shape, and is slidably disposed in a longitudinal direction at a position substantially facing the engaging / disengaging recess 114 in the housing 110. Yes. The movement restricting drive unit is, for example, a motor or a solenoid that moves the movement restricting force 231 in the longitudinal direction.

[0018] Then, the movement restricting cam 231 has a locking pin portion 224A of the lid 220 inserted through the engaging / removing recess 114 at an edge facing the engaging / disengaging recess 114 in the longitudinal direction. A notch recess 232 is provided as a joint. This notch recess 232 is formed with a notch 232A notched in the width direction of the movement restricting cam 231 and a notch formed in a direction that is continuous with the insertion part 232A and intersects the width direction of the movement restricting force 231. The moving part 232B thus formed, a switching part 232C continuously formed in the longitudinal direction of the movement restricting cam 231 that is continuous with the moving part 232B, and a longitudinal direction of the movement restricting cam 231 that is continuous with the switching part 232C. It has a return portion 232D that is notched and inclined toward the edge, and a fixed portion 232E that is continuous with the return portion 232D and is notched along the longitudinal direction of the movement restricting force 231. In addition, the notch recess 232 has a dimension from the one edge in the longitudinal direction of the movement restricting cam 231 to the switching portion 232C, that is, in a state where the locking pin portion 224A is positioned at the switching portion 232C, as shown in FIG. In a state where the optical disk 1 is pivotally supported on the table 212A, the pressing portion 225 of the lid 220 abuts so that the flange 212A2 of the turntable 212A and the optical disk 1 are held. Further, as shown in FIG. 5, when the notch recess 232 is positioned at the fixed portion 232E where the locking pin portion 224A is positioned at the end portion on the one edge side of the movement restricting cam 231 in the return portion 232D, As shown in FIG. 5, the pressing portion 225 of the lid 220 is separated from the optical disc 1 in a state where the optical disc 1 is pivotally supported on the turntable 212A. It is formed so as to be in a positional relationship.

[0019] Then, the movement restricting cam 231 is moved by the movement restricting drive unit so that the insertion portion 232A faces the engagement / disengagement recess 114 when the lid 220 is opened. Further, as shown in FIG. 3, the movement restricting cam 231 is configured so that the cover 220 is further closed when the locking pin portion 224A is engaged with the insertion portion 232A of the notch recess 232, and the biasing force of the biasing means is , The locking pin part 224A enters the moving part 232B and is moved in the longitudinal direction as shown in FIG. 4 by the force of the pressing force that the user closes the lid 220. . Due to the movement of the movement restricting cam 231, a detection switch (not shown) detects the movement of the movement restricting cam 231, the movement restricting drive unit is operated, and the movement restricting cam 231 is moved by the locking piece 224 along the longitudinal direction. Move in the direction indicated. Due to the movement of the movement restricting cam 231, the locking pin portion 224A enters the moving portion 232B force switching portion 232C, the return portion 232D, and the fixed portion 232E. When the movement restricting cam 231 is moved by the movement restricting drive unit until the locking pin portion 224A enters the fixed portion 232E, the detection switch detects that fact and the drive of the movement restricting drive unit is stopped.

[0020] On the other hand, when the user inputs an operation to open the lid 220 at the operation unit, the movement restricting drive unit is driven, and the movement restricting cam 231 is inserted in a direction opposite to the direction in which the lid 220 is closed, that is, inserted. The part 232A is moved toward the position facing the engaging / disengaging recess 114. By this movement, the lock pin 224A force, S fixed rod 232E, return rod 232D, switching rod 232C, moving rod 232B move relative to the river page. When the insertion portion 232A is moved to a position substantially opposite to the engagement / disengagement recess 114, this is detected by the detection switch, and the drive of the movement restricting drive portion is stopped. In this state, the cover 220 is rotated to the open state by the urging force of the urging means, and the opening 111 is opened.

[Operation of Imaging Device]

Next, the operation of the imaging apparatus 100 will be described.

[0022] First, the user operates the operation unit to rotate the lid 220, and opens the opening 111 on one side surface of the casing 110 as shown in FIG. In this state, the movement restricting cam 231 is positioned so that the insertion restricting portion 232A of the notch recess 232 is substantially opposed to the engagement / disengagement recess 114 by the movement restricting drive portion. Then, the optical disc 1 is inserted by the user with the lid 220 opened. By inserting the peripheral edge of the optical disk 1 between one side surface of the housing 110 and the temporary placement piece 113 on the inner peripheral side of the rib 112, as shown in FIG. The optical disc 1 is temporarily placed so as to be held between the temporary placement piece 113. Note that the hole 1A of the optical disk 1 may be placed on the locking claw 212A3 of the turntable 212A with the left side face in FIG. 1 facing upward.

[0023] In this state, the user performs an operation of rotating and closing the lid body 220 so as to close the opening 111, whereby the locking piece 224 of the lid body 220 is engaged with the engaging / disengaging recess 114. As shown in FIG. 3, the locking pin portion 224A engages with the insertion portion 232A of the notch recess 232 of the movement restricting cam 231. Further, when the user applies a pressing force to press the lid 220 against the casing 110, the locking pin portion 224A also enters the moving portion 232B force into the switching portion 232C. Due to the pressing force of this user, as shown in FIG. 4, the pressing portion 225 of the lid 220 comes into contact with the optical disc 1, and the hole 1A of the optical disc 1 rides up the locking claw portion 212A3 of the turntable 212A. Then, the cylindrical portion 212A1 of the turntable 212A is fitted into the inner peripheral side of the hole 1A, and the optical disc 1 is pivotally supported by the turntable 212A.

[0024] Furthermore, when the locking pin portion 224A also enters the moving portion 232B force into the switching portion 232C, the movement restricting cam 231 is moved in the longitudinal direction by the component force of the pressing force that closes the lid 220. This movement is detected by a detection switch (not shown), the movement restricting drive unit is driven, and the movement restricting cam 231 is moved in the direction moved by the locking piece 224 along the longitudinal direction. By the movement of the movement restricting cam 231, the locking pin portion 224A also enters the switching portion 232C, the return portion 232D, and the fixed portion 232E with the moving portion 232B force. In this state, the lid 220 is moved slightly in the opening direction, so that the pressing portion 225 is separated from the optical disk 1 pivotally supported by the turntable 212A, and the optical disk 1 is rotated by the disk rotation driving unit 212. It can rotate with 212A. Further, in this state, even when the user releases the pressing force, the locking pin portion 224A is rotated in the opening direction by the urging force of the urging means, and the state in which the lid 220 is strongly closed is maintained. . 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. [0025] When the optical disc 1 is removed, for example, the movement restricting drive unit is operated by an operation signal generated when the user performs an input operation to open the lid 220 with the operation unit, and the movement restricting cam is operated. The movement restricting cam 231 is moved to a position where the insertion portion 232A of 231 faces the engagement / disengagement recess 114. By the movement of the movement restricting cam 231, the locking pin portion 224 A positioned at the fixing portion 232 E of the notch recess 232 moves sequentially relative to the force return portion 232 D, the switching portion 232 C, and the moving portion 232 B. When the insertion portion 232A is moved to a position substantially opposite to the engagement / disengagement recess 114, this is detected by the detection switch, and the drive of the movement restriction drive portion is stopped. In this state, the cover 220 is rotated to the open state by the urging force of the urging means, and the opening 111 is opened.

[Effects of imaging apparatus]

As described above, in the above embodiment, the opening 111, the turntable 212A that rotatably faces the opening 111, and the information processing of the optical disc 1 that is held by the turntable 212A. A lid body 220 that closes the opening 111 so as to be openable and closable is provided in the housing 110 in which the main body 210 including the information processing unit 213 is disposed. The lid 220 is provided with a pressing portion 225 that protrudes toward the turntable 212A in a state where the opening 111 is closed. Then, when the lid 220 is rotated to open and close the opening 111 by the movement restricting portion 230 disposed in the housing 110, the pressing portion is closed. The turntable 2 225 has a so-called self-chucking function. 2 The lid 220 can be rotated until it comes into contact with one surface of the optical disk 1 held by the 12A. The optical disk 1 is chucked to the turntable 212A. Further, the biasing force by the urging means is changed from the state in which the optical disc 1 is chucked by the movement restricting unit 230 to the state in which the pressing unit 225 is separated from the optical disc 1 in which the pressing unit 225 is blocked while the lid 220 closes the opening 111. Thus, the lid 220 can be moved. Therefore, the optical disc 1 can be chucked in one operation together with the operation of closing the lid 220 without performing the operation of directly pressing and attaching the optical disc 1 with the lid 220 opened and the information processing unit 213 facing. The optical disc 1 can be easily mounted without damaging it by improper pressing force, improving usability and preventing inconvenience such as damage caused by the user touching the information processing unit 213 by mistake. The

[0027] Then, a locking piece 224 having a locking pin 224A is provided on the lid 220. Further, as the movement restricting portion 230, the locking pin portion 224A of the locking piece portion 224 has a notch recess 232 that can be engaged and disengaged, and the locking pin portion 224A engages with the notch recess 232, so that the lid 220 A movement restricting cam 231 that moves in a direction intersecting or orthogonal to the turning direction is provided, and the turning state of the lid 220 is appropriately restricted in accordance with the movement state of the movement restricting cam 231, that is, the pressing portion. After the 225 presses the optical disk 1 and is chucked on the turntable 212A, the pressing member 225 is restricted from moving away from the chucked optical disk 1. Therefore, it is possible to obtain a configuration in which the optical disc 1 can be easily chucked with one operation without damaging the optical disc 1 and the information processing unit 213 with a simple configuration using a cam structure.

[0028] Further, a locking pin portion 224A is provided on one surface of the locking piece portion 224 as a locking portion, and the locking pin portion 224A can be engaged and disengaged by opening and closing the lid 220 as a locking portion. The body 220 has a configuration of a notch recess 232 that is notched so as to open in a direction along a direction along which the body 220 is rotated to close the opening 111. Therefore, the configuration in which the locking pin portion 224A is engaged with and disengaged from the notch recess 232, the movement restricting cam 231 is moved, and the movement restricting cam 231 restricts the movement in the closed state of the lid 220 can be easily obtained.

[0029] Further, as the notch recess 232, the lid body 220 is rotated to close the opening 111. The insertion portion 232A, in which the locking pin portion 224A engages and disengages in a concave shape along the rotation direction, this insertion portion And a moving part 232B formed in a direction that obliquely intersects the moving direction of the lid 220, and a notch formed in a direction that is continuous with the moving part 232B and substantially perpendicular to the rotational direction of the lid 220. The switching portion 232C is formed, and the return portion 232D is formed to be continuous with the switching portion 232C and obliquely cut out in the direction in which the insertion portion 232A opens. For this reason, the locking pin portion 224A is engaged with and disengaged from the notch recess 232, the movement restricting cam 231 is moved, and the movement restricting cam 231 restricts the movement of the lid 220 in the closed state with a simple configuration. Is obtained.

[0030] Further, as the movement restricting portion 230, it is detected by the detection switch that the movement restricting cam 231 is moved by engaging the locking pin portion 224A with the notch recess 232, and based on this detection. Then, the movement restricting cam 231 is moved by the movement restricting drive portion in the moving direction that is moved when the locking pin portion engages the notch recess 232. For this reason, when the pressing force by the user is released, the pressing portion 225 is separated from the optical disc 1 without causing the inconvenience that the locking pin portion 224A is detached from the notch recess 232 and the lid 220 is opened. The closed state can be obtained. Furthermore, even if the user does not continuously apply a large pressing force to the lid 220, the movement regulating cam 231 can be moved by the movement regulating drive unit and the state where the lid 220 is pressed can be maintained.
