DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] Hereinbelow, embodiments of the present invention will be described in detail based on the drawings.

[0024] FIGS. 1 to 3 illustrate embodiment 1 of the invention. As illustrated in FIGS. 1 and 2, an electronic scale 1 according to embodiment 1 includes a scale body 2 and a lid member 3 that is capable of closing a top surface of the scale body 2.

[0025] Peripheral surfaces of the scale body 2 are covered with a comparatively flat case 4 made of resin and a top surface of the case 4 is provided with a weighing tray 5 on which an object A to be weighed is to be laid, a display portion 6 which displays a weight of the object A to be weighed, and various operation buttons such as an ON/OFF switch 7, a working amount corrective operation button 8, and a reset button 9, as illustrated in FIG. 3.

[0026] A weight detection device that measures the weight of the object A to be weighed laid on the weighing tray 5, a control circuit board that includes an operation portion, a storage portion, and the like, a power supply, and the like are incorporated in the case 4, though not illustrated, and a connector 11 for detachable connection of a storage medium B such as a USB memory is provided on a side surface of the case 4 (FIGS. 1 and 2).

[0027] The lid member 3 is mounted at one end of the scale body 2 so as to be capable of opening and closing and so as to stop with a click in a state of rising to a predetermined angle.

[0028] A camera 12 such as a CCD camera and a lighting system 10 such as an LED are installed on a surface of the lid member 3 that faces the scale body 2. The camera 12 is installed in and at a position and an angle that enable imaging of the top surface of the scale body 2 including the weighing tray 5 and the display portion 6 when the lid member 3 opens to the predetermined angle and stops with a click.

[0029] The lighting system 10 automatically emits light when the object A to be weighed is laid on the weighing tray 5 or emits light upon operation of an operation button, and thereby radiates the light toward the top surface of the scale body 2 including the weighing tray 5 and the display portion 6.

[0030] Angles of the camera 12 and the lighting system 10 may be adjustable.

[0031] When the object A to be weighed is laid on the weighing tray 5 after exposure of the surface of the scale body 2 with the rising of the lid member 3 to the predetermined angle and attainment of drive status with operation of the ON/OFF switch 7, the weight detection device measures the weight of the object A to be weighed and the weight is displayed as numbers on the display portion 6.

[0032] Subsequently, the camera 12 images the top surface of the scale body 2 including the weighing tray 5 and the display portion 6 and image data resulting from the imaging by the camera 12 is saved in the storage portion of the control circuit board. The imaging by the camera 12 may be automatically carried out after the weight is displayed on the display portion 6 or may be carried out upon operation of an operation button.

[0033] The connection of the storage medium B to the connector 11 of the scale body 2 enables saving in the storage medium B of the image data resulting from the imaging by the camera 12.

[0034] The electronic scale 1 may transmit the weight of the object A to be weighed that is a measurement result and the image data resulting from the imaging by the camera 12 to electronic equipment, not illustrated, external to the electronic scale 1 with use of means of communication such as Bluetooth (registered trademark) communication or wifi (registered trademark) communication.

[0035] In case where the object A to be weighed is a denture, a filling for a tooth, or the like that is produced by working of expensive precious metal, it is common that a contractor asked for the working informs a client of a value obtained by multiplication of an actual weight by a given coefficient (about 1.05 to 1.15) larger than 1 for the precious metal lost due to the working such as polishing and charges an amount of money corresponding to the weight corrected for a working amount.

[0036] Therefore, a configuration is convenient in which operation of the working amount corrective operation button 8 causes the display portion 6 to display the value obtained by the multiplication of the weight of the object A to be weighed, measured by the weight detection device, by the predetermined coefficient, as a working amount corrected value, and causes the camera 12 to image the object A to be weighed on the weighing tray 5 and the weight displayed as the working amount corrected value, because need for troublesome calculation such as the multiplication by the correction coefficient is eliminated.

[0037] FIG. 4 illustrates embodiment 2 of the invention.

[0038] In embodiment 2, the camera 12 and the lighting system 10 are provided on the top surface of the scale body 2.

[0039] The lid member 3 includes reflection means 13 that reflects an image of the top surface of the scale body 2 including the weighing tray 5 and the display portion 6 toward the camera 12 when the lid member 3 opens to a predetermined angle, on a surface of the lid member 3 that faces the scale body 2. The reflection means 13 may be a mirror, a metallized layer having high reflectance, or the like, for instance.

[0040] Upon the rising of the lid member 3 to the predetermined angle, the operation of the ON/OFF switch 7, and laying of the object A to be weighed on the weighing tray 5, accordingly, the weight of the object A to be weighed is displayed on the display portion 6, the reflection means 13 reflects the image of the top surface of the scale body 2 toward the camera 12, and the camera 12 simultaneously images the object A to be weighed on the weighing tray 5 and the display portion 6 on which the weight is displayed.

[0041] For a reason that the other configurations and the other methods of use are the same as those of the embodiment illustrated in FIGS. 1 to 3, identical parts are provided with common reference characters and detailed description thereof is omitted.

[0042] Image processing in which an image resulting from the imaging as a mirror image is inverted for improvement in visibility may be carried out.
