Claims

[Claims for Utility Model Registration] A recording paper holder that rotatably holds a roll of recording paper, and a recording paper holder that pulls out the recording paper from the recording paper holder, forms an image on the recording paper, and transports the recording paper. an image forming section consisting of a platen roller and a recording head; a cutting section that cuts the image-formed recording paper conveyed from the image forming section in response to an external command; A discharge roller that discharges the recording paper conveyed from the image forming section to the outside; a drive source that rotationally drives the platen roller and the discharge roller; and a normal rotation that discharges the recording paper when the drive source rotates normally. a power transmission mechanism that transmits the driving force of the drive source to the platen roller and the discharge roller in the reverse direction to return the recording paper to the recording paper holder side when the drive source is reversed; , a clutch that interrupts a power transmission system from the power transmission mechanism to the ejection roller, and a clutch that interrupts the power transmission system from the power transmission mechanism to the ejection roller; An image recording device characterized by comprising: a cutoff mechanism that cuts off the connection of the .
