Abstract

PROBLEM TO BE SOLVED: To provide a three-dimensional photographing device that improves a photographing condition by a scan head. SOLUTION: An insertion/withdrawal port 16 of a case 15 is provided with a lower door 40 comprising two slide plates 41, 42 that are mated with each other, and notches 41c, 42c that surround a circumference of a three-dimensional object inserted through the insertion/withdrawal port 16 over the inside and the outside of the case 15 are provided respectively on the slide plates 41, 42 of the lower door 40. Thus, while the three-dimensional object is inserted to the insertion/withdrawal port 16 of the case 15, when the lower door 40 is closed, since the notches 41c, 42c are made approached to the outer circumference of the three-dimensional object, an external light hardly enters the case 15 and it is useful to position the three-dimensional object.

When the measuring table 11 is formed of a transparent plate such as glass, if the measuring table 11 is adhered to the back side, it does not need to be peeled or worn.

The lower door 40 and the upper door 50 are vertically arranged double with respect to the insertion opening 16 of the case 15.

The lower door 40 is used to position the three-dimensional object with the foot as a three-dimensional object inserted into the insertion / extraction opening 16 and to close a gap between the insertion / extraction opening 16 and the three-dimensional object. , Made of a lightweight synthetic resin material.

The upper door 50 protects the lower door 40 by completely covering the lower door 40 in a state where measurement is not performed, and also prevents dust from entering the case 15. It is made of a strong metal material so as not to be damaged. Knobs 51a, 52a and notches 51b, 52b into which knobs 41b, 42b of first and second slide plates 41, 42 of the lower door 40 described below are provided on the butted sides of the upper door 50. .

As shown in FIGS. 9 to 13, each of the lower doors 40 comprises a set of four slide plates 41 to 44, and is provided with respect to a guide rail 60 provided in the top plate 15a of the case 15. They are individually slidably engaged. As shown in FIGS. 12 and 13, the slide plates 41 to 44 of the lower door 40 are not separated from each other.
It is displaced up and down and has a locking piece 41a.
To 44a. As a result, FIG.
As shown in FIG. 5, the first and second slide plates 4
The positions of the butting sides 1 and 42 can be shifted to both ends of the insertion opening 16. Although the upper door 50 has the same configuration,
Illustration is omitted.

Then, of the four slide plates 41 to 44 constituting the lower door 40, the butting sides of the first and second slide plates 41 and 42 which are positioned inside and separated from each other by the palms are:
Knobs 41b and 42b are provided to protrude upward, and semicircular notches 41c and 42c are provided. These two notches 41c and 42c are circular holes surrounding the calf portion of the foot as a three-dimensional object.
Flexible light shielding members 45, such as rubber and urethane resin, are attached to the two notches 41c, 42c so as to protrude. The light shielding member 45 is provided with slits at a plurality of locations in the longitudinal direction of the notches 41c and 42c, and is easily bent up and down. As a result, when the lower door 40 is closed with the foot as a three-dimensional object inserted into the insertion / extraction opening 16, the light blocking member 45 comes into contact with the outer periphery of the calf portion of the foot. And two slide plates 41 and 42 in the lower door 40
No gap is formed between the notches 41c and 42c.

With this configuration, the three-dimensional object can be positioned by the notches 41c and 42c of the lower door 40 in a state where the three-dimensional object is put in the insertion opening 16 of the case 15, and the insertion opening 16 External light does not need to enter through a gap between the object and the three-dimensional object. Therefore, a three-dimensional object can be clearly photographed.

Further, as described above, the two notches 41b and 42b of the lower door 40 can be displaced to both ends of the insertion opening 16 when the upper door 50 is opened. The foot as a dimensional object can be inserted in the opposite direction. That is, it is possible to easily measure both the right foot and the left foot while keeping the arrangement of the three-dimensional imaging apparatus 1 at the current position, which is more preferable.

In addition, the inner surface of the case 15, the inner surface of the lower door 40, and all the components disposed in the case 15 are black so that the laser light emitted from the laser irradiation device 22 of the scan head 13 is not irregularly reflected. It is desirable that By doing so, the laser light applied to the three-dimensional object becomes clear, so that the processing of the image captured by the camera 23 of the scan head 13 can be performed with high accuracy, which is preferable.

It should be noted that the present invention is not limited to only the above embodiment, and various applications and modifications are conceivable.

For example, in the above embodiment, the measuring table 11 is mounted at the center position on the substrate 10 and the top plate 15 of the case 15 is mounted.
The insertion / extraction opening 16 is formed at the center position of the measuring table 11a.
As shown in FIG. 6, it may be installed in a state where it is offset to the footrest 7 side arranged on the side of the three-dimensional imaging apparatus 1. In other words, when a human foot is used as a three-dimensional object, one foot is inserted into the insertion / extraction opening 16 of the case 15 and measurement is performed. For example, even a person with a short inseam can measure with the shoulder width. Be able to measure.

[0036]

According to the first to sixth aspects of the present invention, the lower door is closed in a state where the three-dimensional object is inserted into the insertion / extraction opening so that the notch is made closer to the outer periphery of the three-dimensional object. This makes it difficult for external light to enter the case, and is also useful for positioning a three-dimensional object. This is advantageous in accurately recognizing a shape, such as a clear image of a three-dimensional object.

In particular, in the invention according to the second aspect, since a gap formed between the three-dimensional object and the notch of the door can be eliminated in a state where the three-dimensional object is inserted into the insertion opening, the external light to the inside of the case can be eliminated. Is improved, and the photographing conditions can be further improved.

Further, in the invention according to the third aspect, even when a three-dimensional object having a different size is inserted into the insertion opening, the positioning can be appropriately performed regardless of the size, which is preferable.

Further, in the invention according to claim 4, it is advantageous to bring the three-dimensional object inserted into the insertion / extraction opening into a predetermined posture.

According to the fifth aspect of the present invention, when a three-dimensional object is irradiated with a laser beam and photographed, the laser beam can be prevented from being irregularly reflected inside the case. This is advantageous in that image processing can be easily performed, for example, it can be sharpened.

Further, in the invention according to claim 6, in a situation where the insertion / extraction opening is arranged at the center of the case and one person's leg is used as a three-dimensional object, the width of the straddle of the case is widened and the measurement with the shoulder width is performed. In consideration of the case where it becomes impossible to perform, it is preferable that even the person with short inseam can measure with the shoulder width by offsetting the insertion / extraction opening from the center of the case.

According to the seventh and eighth aspects of the present invention, the leading end of the printed paper discharged from the discharge port of the printing apparatus can be stopped by merely inserting the leading end of the paper into the discharge window of the system rack. Can be prevented from falling inside the door without reaching the paper ejection window.
