The amount-

The money amount display unit 300 is installed in the main body 100 and may include a controller 310 and a display 320.

The display 320 is preferably disposed on the outer surface of the main body 100.

In the controller 310, an amount corresponding to the weight of money including a coin or a banknote is set in advance.

The controller (310) is electrically connected to the weight measuring unit (200).

The controller 310 may display the amount corresponding to the weight measured and transmitted from the weight measuring unit 200 through an external display 320.

In the meantime, the main body 100 according to the present invention is further provided with an image sensor 340 which can acquire an image of money placed on the seating part 110. [

The image sensor 340 may transmit the acquired image to the controller 310 in the form of an electrical signal.

The controller 310 receives the image obtained from the image sensor 340 and processes the image by image processing to discriminate and determine whether the money is a coin or a bill.

The reference image for determining whether a coin or a banknote is present may be preset in the controller 310 as described above.

The controller 310 does not display the amount corresponding to the weight measured by the weight measuring unit 200 through the display 320 when the image processing result is not an image for a coin or banknote.
