Claims

[Scope of utility model registration request]

An image buffer that stores image signals, a shift register that converts the parallel image signals stored in the image buffer into serial image signals, and a handshake that receives the image signals sent by the host device and controls the image buffer and shift register. An image signal receiving circuit for a laser beam printer, characterized in that the image signal receiving circuit comprising an image signal receiving circuit circuit is provided with an error detection circuit for detecting that a host device has transmitted an image signal at a timing that allows normal printing. Receiving device.
