Claims

[Claim for Utility Model Registration] A pen block that feeds paper in the X direction by a drive roller and a pinch roller, has two movable pinch rollers, and freely moves in the Y direction perpendicular to the X direction. In an initial state detection device for a recording device that detects the initial setting of the recording device, a position indicator is provided to indicate the position of the pen block, and the setting position of the movable pinch roller is changed according to the paper width of the recording paper used. , an optical sensor mounted on the pen block to detect transmission of light in the X direction; a home position light shielding plate provided at a position to block the light of the optical sensor to indicate a reference point of the recording device in the Y direction; A Y-side light shielding plate that is fixed to the first movable pinch roller and is provided at a position that blocks the light from the optical sensor and has a different length in the Y direction from the home position light shielding plate; a second movable pinch roller; a Y-side light shielding plate that is fixed at a position to block light from the optical sensor and has a length in the Y direction different from that of the home position light shielding plate; is driven in the direction of the home position light shielding plate to measure its position, and then driven in the opposite direction to measure the position of the -Y side light shielding plate and the +Y side light shielding plate. An initial state detection device for a recording device, comprising: control means.
