Abstract: PURPOSE: To prevent a lower cover from being simply opened even when a heavy commodity is contained and packaged. CONSTITUTION: An insertion slit 22 is provided on a boundary between a bottom plate 18 and an interposing plate 21. An insertion plate 23 is extended from a lower edge of a front plate 4 (or a back plate 8). As a result, the interposing plate 21 is interposed on the inner surface of the front plate 4, the insertion plate 23 is inserted into the insertion slit 22 to be overlapped on the inner surface of the bottom plate 18, and the edge of the insertion slit 22 on the interposing plate 21 is fastened to the insertion plate 23. Then, the gravity of a commodity is applied to the bottom plate 18, and the interposing plate 21 tends to disengage from the inner surface of the front plate 4.  However, since the edge of the insertion slit 22 on the interposing plate 21 is fastened to the insertion plate 23, disengagement of the interposing plate 21 from the inner surface of the front plate 4 can be prevented. Therefore, a lower cover is not simply opened even when a heavy commodity is contained and packaged.

Title: Recognizing method and apparatus for three-dimensional shape
Inventor: IDE KENSUKE
IPC: G01B11/24
Filed: 1990-03-08
Abstract: PURPOSE:To discriminate a real image from a virtual image by a method wherein a slit beam is projected to an object to be measured, and then an angle defined by the three-dimensional shape recognized when a slit beam generator is moved and the slit beam is compared with an angle defined by the slit beam and an optical axis of a camera. CONSTITUTION:A slit beam generator 3 projects a slit beam 4 to an object 2 to be measured, while a camera 5 feeds image data of an image irregularly reflected by the object 2 to an image take-in device 6, so that a coordinate operator 7 operates the coordinates. Supposing that the coordinates of a shape X are operated from a virtual image when the slit beam 4 is irregularly reflected at the horizontal surface and regularly reflected at the longitudinal wall while the distance between the slit beam 4 and longitudinal wall is held small, an angle theta defined by an optical axis of the camera 5 and slit beam 4 is larger than an angle phi defined by the operated shape X and slit beam 4, that is, the shape not seen from the camera 5 is operated. Therefore, if the angle phi is measured by a shape inclining angle detecting device 8, and only when a real image/virtual image discriminator 9 compares and recognizes the angles as phi>theta, the shape is judged as the real image.
