[0029]
Hereinafter, an example of the operation of the imaging stage according to the present embodiment will be described.
[0030]
In the state in which the illumination lamp L is stored (the state of the illumination lamp L on the front side in FIG. 1) (second position), the side of the opening of the lamp cover 16 formed by the enclosure 3 and the bottom plate 4 The cam follower is engaged with the cam lever 22 so as to be rotatable by a follower pin 24 and is always pressed against the upper end surface of the linear cam 6 (7) by the spring 21. Since the recessed portion 6a (7a) on the end face is obstructed to prevent the movable arm A1 from sliding in the horizontal direction, the above-mentioned fitting is possible even when handling the lamp cover 16 and carrying the whole. There is no concern of causing problems such as separation.
[0031]
If the lamp 12 is turned on in the above state, the light is reflected by the reflector 13 and from the end surface of the light guide plate 2 via the transparent side cover 30 while being shielded from leaking outward by the fitting portion. The light is incident on the inside, and the lighting panel P for backlight illumination is caused to emit light so that photographing with backlight illumination is possible.
[0032]
On the other hand, when photographing with front light illumination, when the release knob 26 is pushed down against the force of the spring 29 (operation S1), the release knob 26 pushes the tip end of the drive end 22b of the cam lever 22 facing it downward. Therefore, the cam lever 22 rotates, and the cam follower 23 on the driven end 22a side is released from the recessed state of the recess 6a (7a) on the upper end surface of the linear cam 6 (7), and the release knob 26 is moved horizontally. Also when returning to the original position, the cam follower 23 moves again to a position where it does not fall (operation S2), and the movable arm A1 also moves in the lateral horizontal direction along with this and becomes slidable. This release operation is performed simultaneously with respect to the left and right movable arms A1, but naturally it is also possible to cancel this when only one side is locked.
[0033]
If the movable arm portion is moved further outward (operation S3), the opening of the lamp cover 16 is disengaged from the fitting with the convex edge portions of the enclosure 3 and the bottom plate 4, while the movable arm A1 is spring 21. The pair of guide pins 9 planted on the swing arm 8 are slightly slidable in the guide slits narrowed on the guide rail 5. Thus, the movable arm A1 is kept in a horizontal state until reaching the end of movement.
[0034]
As described above, the guide slit 5a provided in the guide rail 5 is provided with the notch 5b at a position facing the guide pin 9 at the end position of the lateral outward movement of the movable arm A1, and the movable arm A1 is located at this position. Thus, the spring 21 is turned upright (operation S4), and the guide pin 9 is prevented from moving by the inner edge of the notch 5b. 1 (the first position). If the lamp 12 of the lighting lamp L is turned on in the above state, the illumination light emitted from the lamp 12 is placed on the object B such as a document (not shown) or an arbitrary object placed on the object table B. Irradiation directly from above, it is possible to shoot with front light illumination.
[0035]
When storing the lighting lamp L, the procedure is reversed. That is, the movable arm A1 is rotated (inverse of the operation S4) and is slid inward while keeping the level (inverse of the operation S3), and the opening of the lamp cover 16 is formed on the convex edge of the enclosure 3 and the bottom plate 4. The cam follower 23 falls into the recess 6a (7a) at the upper edge of the guide rail 5 and the movable arm A1 is automatically locked in the position storage.
[0036]
As illustrated in FIG. 1, if a plurality of illumination lamps L are arranged symmetrically on the mounting table B, various types of illumination on the subject on the mounting table B can be performed more uniformly. Moreover, it goes without saying that the front light illumination may be performed by one illumination lamp L and the backlight illumination may be performed by the other illumination lamp L at the same time as necessary.
[0037]
As described above, according to the imaging platform of the present embodiment, it is possible to arbitrarily select and execute either the front light illumination or the backlight illumination with a simple operation, and various illuminations can be easily performed. Can be realized.
[0038]
