A photosensitive drum includes a cylindrical member having a photosensitive body disposed thereon, and first and second helical gears arranged axially side-by-side on one end of the cylindrical member. The first helical gear is disposed axially outward of the second helical gear, and the first helical gear has an outer diameter greater than an outer diameter of the second helical gear. The first helical gear meshes with a drive gear to rotatingly drive the drum. A sleeve gear of a developing sleeve is selectively engaged with one of the first and second helical gears, depending upon a kind of toner used.

Electronic equipment comprises a store for storing messages, apparatus for processing time information and generating an output at the beginning of each predetermined time period. The messages and time information may be displayed and one of the messages can be selected at random at the start of each time period and displayed with time information in response to the output of the time information processing means, the same message being prevented from being displayed more than once in a time period that is longer than the first mentioned time period.
摘要:
A printer having plural type font wheels for function symbols of different colors and plural type font wheels for numerals of different colors fitted on a rotary shaft, wherein the plural type font wheels for numerals are displaced along the shaft for each printing action. The plural type font wheels for function symbols or for numerals are provided with a mask for exposing only one type font wheel of a desired color but covering all other wheels to enable multi-color printing. The selection of the type font wheel for printing is achieved by the displacement of plural type font wheels in the digit direction with respect to the mask.
