and the control unit causes the illumination mechanism to emit the illumination pattern indicating at least one of the outer periphery of the printing range, the center position of the printing range or any corner position of the outer periphery of the printing range, based on the light emission pattern information. ### Claim 4 (depends on 2) The recording device according to claim 2, wherein the light emission pattern information corresponds to information representing an external shape of a pattern included in print data; and the control unit causes the illumination mechanism to emit the illumination pattern indicating the external shape of the pattern, based on the light emission pattern information. ### Claim 5 (depends on 1) The recording device according to claim 1, wherein the illumination instruction information includes information representing a color of the illumination pattern emitted by the illumination mechanism; and the control unit changes the color of the illumination pattern, based on the information representing the color of the illumination pattern. ### Claim 6 (depends on 1) The recording device according to claim 1, further comprising a colorimeter mechanism configured to measure a color tone of the medium, wherein the control unit automatically changes a color of the illumination pattern in accordance with measured color tone information. ### Claim 7 (depends on 1) The recording device according to claim 1, wherein the illumination instruction information includes information representing a light quantity of the illumination pattern emitted by the illumination mechanism; and the control unit changes the light quantity of the illumination pattern, based on the information representing the light quantity. ### Claim 8 (depends on 1) The recording device according to claim 1, further comprising an illuminometer mechanism configured to measure an illuminance of the placing surface on which the medium is placed, wherein the control unit automatically changes a light quantity of the illumination pattern in accordance with the illuminance measured. ### Claim 9 A control method for a recording device, the recording device comprising: a recording unit configured to perform recording on a medium; a placing part including a placing surface for placement of the medium, the placing part being configured to move in a front-rear direction including a position facing the recording unit; an illumination mechanism disposed at the placing part and configured to emit light from a light source provided inside the placing part in an illumination pattern toward the placing surface; and an input unit configured to receive illumination instruction information specifying the illumination pattern, wherein the illumination pattern of the illumination mechanism is configured to be changed based on the illumination instruction information received by the input unit, the illumination mechanism includes a plurality of light shielding plates corresponding to the illumination pattern, and the illumination instruction information includes information specifying the light shielding plate; and the control unit makes a notification of the information specifying the light shielding plate. ### Claim 10 A recording system comprising: a recording device; a host device; a recording unit configured to perform recording on a medium; a placing part including a placing surface for placement of the medium, the placing part being configured to move in a front-rear direction including a position facing the recording unit; an illumination mechanism disposed at the placing part and configured to emit light from a light source provided inside the placing part in an illumination pattern toward the placing surface; and a reception unit configured to receive an illumination instruction information specifying the illumination pattern from the host device; and a recording side control unit, wherein the host device includes: a transmission unit, and a host side control unit, the host side control unit transmits the illumination instruction information to the recording device by using the transmission unit, and the illumination pattern of the illumination mechanism is configured to be changed by the recording side control unit, based on the illumination instruction information received by the reception unit, the illumination mechanism includes a plurality of light shielding plates corresponding to the illumination pattern, and the illumination instruction information includes information specifying the light shielding plate;
