Preferably, a groove is provided in the bottom of the rest to allow the rest to fit over the handle of an amplifier. The image processing device generates a binary image by detecting edges of the photographed image, erases edges contacting an outermost edge of the photographed image, and extracts the areas based on the binary image from which some of the edges are erased. , a transmission gate for inputting an inputted pulse signal a and controlling the passage of the inputted pulse signal a in response to the application of two delayed pulse signals from among the plurality of different delayed pulse signals b1, b2,. Given a parameter name, the code may be executed for determining the price in an event scope.
