It is an object to identify which of a plurality of rotationally moving drawing pockets a drawing object has entered into, without using a detecting means unit that moves together with the drawing pockets, from a result of detection by a fixedly arranged detecting means unit.The present mechanical drawing machine includes a drawing pocket forming member which can hold a drawing object having entered into each drawing pocket inside of the drawing pocket while rotationally moving so as to pass through a site adjacent to a stationary base, an object detecting unit which is provided on the stationary base, and detects that a drawing object which is held inside of the drawing pocket has passed through an object detecting site on an orbit of the drawing pockets, a mark forming and moving member which forms a plurality of mutually different marks corresponding to the drawing pockets, respectively, and rotationally moves the marks in synchronization with rotational movement of the drawing pocket forming member, a mark content reading unit which is provided on the stationary base, and reads a mark content when each mark passes through a mark detecting site on an orbit of the marks, and a pocket identifying unit which, based on a timing at which the object detecting unit detected passage of a drawing object or a mark content read by the mark content reading unit, identifies a drawing pocket into which the drawing object has entered.
