    摘要: A sheet feeding unit includes a sheet forwarding unit for forwarding sheets from a sheet storing unit, a key input portion, a sheet detection gate, and a control unit. In one embodiment, the sheet forwarding unit repetitively performs its function after an operation start instruction until either the sheet detection gate detects a sheet from the feeding cassette or until the number of repetitions of the sheet forwarding unit reaches a predetermined number. An error process is performed when the number of repetition reaches the predetermined number without the gate detecting a sheet. Also, the sheet feeding unit compares the number of times a sheet is fed from the sheet feeding unit with the number of times the sheet if forwarding to determine the status of the feeding roller.

    摘要: A paper supplying deck is insertable into and withdrawable from a paper supplying portion of a body resulting in electrical connection between the side of the paper supplying deck and the side of the body through a drawer-type connector when the paper supplying deck is inserted and interruption of such electrical connection when the drawer is withdrawn. The paper supplying deck has a paper carrying portion with a paper width setting mechanism and a variable resistor the resistance value of which is changed in dependence on the paper width setting mechanism, thereby changing an output paper width detecting voltage. On the wide of the paper supplying deck, a resistance which prevents the paper width detecting voltage from amounting to a power source voltage even though the resistance value of the variable resistor reaches a maximum value, is connected in series with the variable resistor. On the side of the body, a pull up resistance is connected with the connector to discriminate between voltages in the connector when the paper supplying deck is mounted and when the paper supplying deck is not mounted.

    摘要: In a copying processing performed several times from the depression of a copy button of a copying machine until the surface potential of the photoreceptor drum is stabilized, a voltage sufficiently high for correcting the rise characteristic of the photosensitive layer on the drum surface is applied to a charger. A main circuit having a controlling portion to realize this corrects the output voltage of the high-voltage generating circuit which applies a high voltage to the charger to a voltage value necessary for the drum surface to be charged at a stable potential level. The main circuit charges the drum surface at the stable potential level necessary for development from copying of the first sheet.

    摘要: Rotary electronic component of the invention has a contact board and an elastic contact. The contact board, including an annular contact having an arc-segmental portion split by a slit with a predetermined width and signaling contacts disposed at spaced positions and in electrical continuation with the arc-segmental portion, is fixed in a resin molding with the annular contact exposed on the top plane of the resin molding. The elastic contact slides on the contact board along the annular contact. In this rotary electronic component, a stress occurring when the annular contact is fixed by molding on to the contact board is relaxed owing to presence of the slit. Thus, a rotary electronic component generating an electric signal with a stabilized waveform over a long time can be obtained.
