When the operation dial 69 is rotated, the lock pin 72 is connected to the moving member 70, and the tip of the lock pin 72 that protrudes from the side of the apparatus body 2 is stored in the corresponding support column 31. The lock hole 80 is inserted and locked.

  In the above-described embodiment, the rotation shaft support portion 12, the shaft holder 17, the rotation center shaft 19, the rotation shaft center portion 20, the one-way clutch 22, the support shaft rotation shaft 23, and the shaft portion 56 are all hollow. Yes, the holding plates 45 and 63 are provided with an insertion hole in the center so that a wire harness for ensuring electrical connection can be inserted.

  A control unit (not shown) that performs predetermined control based on operations of various operation buttons 15 and the like of the operation panel unit 13 is disposed in the apparatus main body 2. In addition, the electrical connection between the control unit and the control circuit unit (not shown) of the imaging camera 3 is sequentially inserted through the hollow rotation shaft support 12, the rotation center shaft 19, the one-way clutch 22, and the like. It is ensured by a wire harness (not shown) routed around the rotation support 31, the slide support 35 and the illumination lamp support 6. Furthermore, various connection sockets and the like for ensuring connection with a power source and external devices are disposed on the back surface and side surface of the apparatus body 2.

  In the storage form of the material presentation device 1 described above, the imaging camera support column 4 and the illumination lamp support column 6 are both tilted on the left side surface of the device body 2 as shown in FIG. The right-angle bent part 54 and the camera support part 55 of the imaging camera support column 4 are tilted to the near side in front of the apparatus main body 2. The imaging camera 3 attached to the camera support part 55 is located in a space formed by the front side of the apparatus main body 2 and the side part of the operation panel part 13. The illumination lamp chamber 66 formed in the right-angled bent portion 65 of the illumination lamp support 6 is tilted to the upper surface on the near side of the apparatus main body 2.

  In order to shift from the storage mode to the setup mode of FIG. 1, first, when the imaging camera column 4 is locked at the storage position, the lock mechanism 68 is unlocked. The lock mechanism 68 rotates the operation dial 69 to move the operating member 70, and moves the tip of the lock pin 72 backward from the lock hole 80 of the rotation column 31 into the apparatus main body 2 by an interlocking member interlocked therewith. To do. Subsequently, the rotating column 31 of the imaging camera column 4 is rotated to stand. The rotating support column 31 has a protrusion 64 formed on the side of the support column cover 32b, and the illumination lamp support column 6 that is pressed in contact with the protrusion 64 rotates in conjunction with it.

  The rotation shaft 23 for the rotation column 31 is inserted into a one-way clutch 22 that is inserted into the rotation shaft center portion 20 of the rotation shaft support 12. The one-way clutch 22 is set so as to be free with respect to rotation in the direction in which the rotary support 31 is raised. Therefore, the imaging camera column 4 can be raised with a relatively small force. The one-way clutch 22 exhibits a clutch function with respect to rotation in a direction in which the rotating column 31 is tilted. Therefore, when tilting the pivot column 31, the pivot shaft center portion 20 rotates against the column holding bracket 18 against the braking force by the clutch function of the one-way clutch 22. The imaging camera column 4 can be held at an arbitrary rotation angle by the free stop function based on the frictional resistance at this time.

  As described above, when the rotating column 21 rotates, the slide mechanism 35 operates to slide the slide column 33. The large-diameter gear 37 of the belt transmission device portion 36 of the slide mechanism 35 is rotatably inserted into a gear shaft support portion 40 that is inserted into the rotation center shaft 19 that passes through the rotation column 31. When the rotating column 21 rotates in the standing direction, the large-diameter gear 37 and the gear shaft support unit 40 rotate relatively in the direction opposite to the rotating direction of the rotating column 21. The small diameter gear 38 whose rotation is transmitted by the toothed belt 39 rotates in the same direction as the large diameter gear 37. The rack 48 is moved by the rotation of the gear 47 of the gear rack portion 46 fixed to the small diameter gear 38. Since the rack 48 is attached to the connecting portion 53 of the slide column 33 to which the slider 49 is connected, the slide column 33 is pushed out from the tip opening 31a of the rotating column 21, and the imaging camera 3 is automatically set to a predetermined position. Set up in position (Figure 4).

  When tilting the rotating column 21, the large-diameter gear 37 and the gear shaft supporting portion 40 are relatively rotated in a direction opposite to the rotating direction of the rotating column 21, and the slide column is operated by an operation reverse to the above. 33 is automatically pulled into the rotating column 21 (FIG. 5). When an unexpected force that slides the slide column 33 is applied from the outside, the large-diameter gear 37 and the gear shaft support portion 40 are relatively rotated so that the toothed belt 39 is not overloaded. The toothed belt 39 is protected from being cut.

  Moreover, when the imaging camera support column 4 stands, the illumination lamp support column 6 stands up in conjunction with it. In this set-up position, the illumination lamp chamber 66 is positioned slightly lower on the rear side of the imaging camera 3 when viewed from the front of the apparatus body 2. As shown in FIG. 8, since the illumination window 67 of the illumination lamp chamber 66 is inclined such that the front side 67a is higher than the back side 67b, the lamp light illuminates the central portion of the material placement surface 11. Can do. Furthermore, in the presentation using this material presentation apparatus 1, since the operation panel part 13 faces the presenter side, the illumination window 67 of the illumination lamp chamber 66 does not enter and viewers do not feel dazzling.

  In the illumination lamp column 6 interlocked with the rotating column 21, the spacer 59, the shaft cover 60, the spacer 61, and the wave washer 62 are inserted into the shaft portion 56, and the wave washer 62 is pressed. As a result, the illumination lamp column 6 has a free stop function in which a predetermined brake acts on the rotation relative to the rotation column 31. Therefore, as shown in the two-dot chain line in FIG. It can be tilted to an arbitrary position behind the camera column 4.

  At the storage position where the imaging camera column 4 and the illumination lamp column 6 are tilted, the operation dial 69 is rotated, and the lock pin 72 is engaged with the lock hole 80 provided in the rotation column 31 and locked. Thereby, it can prevent that the imaging camera support | pillar 4 rotates unexpectedly at the time of conveyance.

  As is clear from the above description, the document presentation device 1 according to the embodiment rotates the imaging camera column 4 and tilts it to the storage form, so that the imaging camera column 4 is rotated by the manual operation dial 69. Since the lock mechanism 68 for locking the device to the apparatus main body 2 is provided, it can be locked only when the user desires, and it is easy to use. Therefore, no large force is required when raising the imaging camera support column 4.

  Further, the lock mechanism 68 includes an operation dial 69 that appears on the upper surface of the apparatus main body 2, an operation member 70 that engages and interlocks with the operation dial 69, and a lock pin 72 that engages and interlocks with the operation member 70. Since the lock pin 72 is engaged and locked in the lock hole 80 provided in the imaging camera support column 4 by the operation of the operation dial 69, the entire structure of the lock mechanism 68 is made compact. And can be incorporated into the apparatus main body 2. Further, since the operation dial 69 appears on the upper surface of the apparatus main body 2, the operability is improved.
