A printer according to the present disclosure includes a head printing on a work, a driving motor moving at least one of the head and the work in order to change a print position on the work, a rotary encoder and an encoder counter determining a position of the head relative to the work, a control device supplying electric power to the encoder after excitation of the driving motor is turned off during printing and enabling the encoder counter to continue counting. ## Claims ### Claim 1 An inkjet recording apparatus comprising: a recording head recording on a recording medium; a driving motor moving at least one of the recording head and the recording medium in order to change a recording position on the recording medium; position determining means for determining a position of the recording head relative to the recording medium; and controlling means for controlling the position determining means such that the relative position of the recording head is continuously determined by the position determining means after an emergency stop command is generated during recordation to turn off excitation of the driving motor. ### Claim 2 (depends on 1) The inkjet recording apparatus of claim 1, wherein the position determining means comprises: a rotary encoder detecting a rotor position of the driving motor; and an encoder counter counting a signal output from the rotary encoder. ### Claim 3 (depends on 2) The inkjet recording apparatus of claim 2, wherein the controlling means supplies electric power to the rotary encoder and enables the encoder counter to continue counting the signal output from the rotary encoder after the emergency stop command is generated such that the relative position of the recording head is continuously determined by the position determining means. ### Claim 4 (depends on 1, 2, 3) The inkjet recording apparatus of any one of claims 1-3, further comprising position extracting means for extracting from the position determining means a position of the recording head relative to the recording medium at a time when a restart command is generated after the emergency stop command is generated. ### Claim 5 (depends on 4) The inkjet recording apparatus of claim 4, further comprising motor control means for controlling the driving motor to move the recording head from the relative position extracted by the position extracting means to a restart position. ### Claim 6 (depends on 4) The inkjet recording apparatus of claim 4, wherein the position extracting means further extracts from the position determining means a position of the recording head relative to the recording medium at a time when the emergency stop command is generated. ### Claim 7 An inkjet recording apparatus comprising: a recording head recording on a recording medium; a first driving motor moving the recording head in a scanning direction; a second driving motor moving the recording head or indirectly moving the recording medium in a vertical scanning direction which is perpendicular to the scanning direction and is parallel to a recording side; first position determining means for determining a position of the recording head relative to the recording medium in the scanning direction; second position determining means for determining a position of the recording head relative to the recording medium in the vertical scanning direction; and controlling means for controlling the first and second position determining means such that the relative positions of the recording head are continuously determined by the first and second position determining means, respectively, after an emergency stop command is generated during recordation to turn off excitation of the first and second driving motors. ### Claim 8 (depends on 7) The inkjet recording apparatus of claim 7, wherein the second driving motor moves the recording head indirectly. ### Claim 9 (depends on 1, 7) The inkjet recording apparatus of claim 1 or 7, further comprising: protecting means for protecting the recording head during the recordation; and detecting means for detecting opening or closing of the protecting means during the recordation, wherein the detecting means generates the emergency stop command when the opening of the protecting means is detected. ### Claim 10 (depends on 1, 7) The inkjet recording apparatus of claim 1 or 7, further comprising ink curing means for curing Ultraviolet (UV) ink ejected by the recording head on the recording medium. ### Claim 11 A control device for controlling an inkjet recording apparatus comprising a recording head recording on a recording medium, a driving motor moving at least one of the recording head and the recoding medium to change a recording position on the recording medium, and position determining means for determining a position of the recording head relative to the recording medium, the control device comprising: controlling means for controlling the position determining means such that the relative position is continuously determined by the position determining means after an emergency stop command is generated during recordation to turn off excitation of the driving motor. ### Claim 12 (depends on 11) A program for enabling a computer to function as the controlling means in the control device of claim 11. ### Claim 13 (depends on 12) A computer-readable recording medium recording the program of claim 12.
