Claims (1)

[Claims for Utility Model Registration] (1) An actuating member that is movable in the width direction in accordance with the width size of the recording medium positioned and placed on the manual feed surface, and an actuating member that is substantially connected to the actuating member and that and a control means whose output signal can be varied in accordance with the moving distance of the actuating member, and configured to be able to control the image layout formed on the photoreceptor drum based on the output signal from the control means. An electrophotographic device characterized by: (2) Based on the control signal, adjust the image writing start position and image writing width formed on the photoreceptor drum, and select the direction in which the image is formed on the photoreceptor drum as necessary. 1. An electrophotographic apparatus according to claim 1, which is configured to be switchable. (3) A utility model registration request for switching the image forming direction when a control signal corresponding to the width size of the recording medium becomes equal to, less than or greater than a predetermined setting value. The electrophotographic device according to scope 1 or 2. (4) means for generating a reference voltage corresponding to a predetermined width size; and means for comparing a control signal voltage corresponding to the width size of the recording medium with the reference voltage; The electrophotographic apparatus according to claim 3, wherein the electrophotographic apparatus outputs a signal for switching the image forming direction when the voltage becomes lower than or higher than a reference voltage. (5) In an electrophotographic device in which a manual feed mechanism is configured separately from the device main body, the operating member is disposed on the device main body side facing the manual feed surface, the scope of utility model registration claims 1 to 4. Any one of the items up to
The electrophotographic device described in Section 1. (6) The electrophotographic apparatus according to claim 5, wherein the operating member is configured to be movable in conjunction with a paper size regulating member disposed on the manual feed mechanism side.
