Abstract: An electrophotographic copying machine includes a mouse connected to a main unit to input positional information for editing. When the mouse is moved on an original for editing, pulses are generated from the mouse according to a rotation of a roller, which are counted by a counter of a microcomputer. A count value of the counter is utilized as positional data. In order to display a copy quantity, there is provided a segmental display. In the editing mode, a predetermined segment of the segmental display is selectively lightened so as to display the states of sequential position designations by the mouse. Therefore, it is possible to visibly confirm the state of the position designations for editing.

Abstract: An electrophotographic copying machine comprises a mouse which is connected to a main unit by a connecting cord and is for inputting positional information for editing. The mouse has a roller whose peripheral side surface is exposed from a case. When the mouse is moved while the peripheral side surface of the roller is brought in contact with a surface of an original, pulses are generated from the mouse attending on rotation of the roller, and these pulses are counted by a counter of a microcomputer. The counted value of the counter is utilized as positional data for editing by the microcomputer. Based on that positional data, the microcomputer partially and selectively lightens of a plurality of LED elements constituting a LED array. Therefore, an electrostatic latent image on a photoreceptor-drum is partially erased so that "masking or "trimming" of an image in an area defined by the positional data is executed.

Abstract: A ceiling fan comprises a cover provided with a rotor and wings, a stator, a fixed shaft attached to the stator and a member mounted on the fixed shaft and functioning as a protection member and/or fitting member. Thereby the fan is under protection, and parts of the fan and other equipments are easily fitted thereto.
