As described above, according to the present invention, the image pickup portion is rotatably attached to the support member so that the locus of the optical axis of the image pickup portion forms a circle. For example, the side surface (excluding the top surface) of a three-dimensional object placed on the table.
Also, when you want to read a range other than the readable range of the original, you can easily read the three-dimensional object or original without rotating or moving it each time, and you can make it an image input device with good operability and no hassle. it can. Further, by remotely controlling the rotation operation of the image pickup unit using a remote controller or the like, the range of use thereof is further expanded, and a more convenient image input device can be provided.

Further, a lock mechanism capable of preventing rotation of the vertical support portion is provided, and the lock mechanism folds the horizontal support portion so that the horizontal support portion rotates in the vicinity of the rotation fulcrum portion of the horizontal support portion. Since it is configured to be released by the convex portion provided in the vicinity of the fulcrum portion, the guide shaft 145 and the cam groove 116-in the rotation fulcrum portion of the horizontal support portion 3a.
Even if there is play in the Z ₂ direction (play at the root) at the position of the guide shaft 145 when fitted with 3, 116-4, there is a convex portion 53 ′ from the center of the rotation fulcrum of the horizontal support 3a. Since the distance to is short, the amount of change in the convex shaped portion 53 'with respect to the play at the root is small, and is less likely to be affected by the play. In particular, even if the guide shaft 145 is in a position where the guide shaft 145 is fitted in the cam groove 116-4 in the direction in which the convex portion 53 ′ moves away from the button 54 due to the weight of the horizontal support portion 3 a, the lock function is reliably released. It is possible to provide an image input device having high reliability.

Further, according to the present invention, since the sensor light receiving portion for receiving the light from the wireless remote controller is provided on the supporting member so as to be retractable, the sensor light receiving portion is erected from the supporting member when the wireless remote controller is used. When not in use and using the wireless remote controller, the sensor light receiving part is stored in the support member so that it can be a convenient device that does not get in the way, looks good, and does not damage the sensor due to an unexpected accident. it can. In addition, by using the sensor light receiving unit in a state of standing upright from the support member, for example, at a lecture or a presentation, the lecturer stands and explains the image of the paper attached to the wall next to the image input device while explaining the image. Since I want to read different things with the input device, I use the wireless remote controller from the side of the device to remotely control the focusing, zooming, rotation of the imaging unit, and other functions such as switches, lecturers and students. By interacting with the student, even when the student wants to perform the same remote operation from the rear of the device using the wireless remote controller, the sensor light receiving unit can detect the light from the wireless remote controller. As described above, in the remote operation using the wireless remote controller, the angle range in which the sensor light receiving unit can receive light can be widened, and the wireless remote controller can function from almost all directions. Further, since the sensor light receiving portion can be rotated or slid with respect to the support member to stand up,
It is a wireless remote control function that is easy to operate, has few components, is low in cost, and does not require space. By using such an image input device, the range of use thereof can be further expanded, and the device can be made more convenient and easy to operate.
