An image forming machine having a reversing transport path in which a transport direction of a sheet introduced from an image forming transport path is reversed, a returning path in which the sheet reversely transported from the reversing transport path is returned below the image forming transport path with the directions of the face and back of the sheet being unchanged, and an inverting transport path in which the sheet from the returning path is turned upside down and readmitted into an upstream portion of the image forming transport path. A finisher including a sheet receiving stand placed below the returning path is provided, and at least one send-in unit for selectively sending in different length sheets onto the sheet receiving stand is disposed in the returning path.

A feeder apparatus arranged on a side of a main body of an image forming apparatus is provided with a top door and a vertical door. The top door is provided in an opening defined above a sheet stacker, and the vertical door is provided in an opening defined on a side of the sheet stacker to enable an operator to replenish sheets inside the feeder apparatus. Switches are provided to detect as to whether the top door or the vertical door is opened. The feeder apparatus is constructed in such a manner that upward movement of the sheet stacker is suspended when the top door is detected to be opened and that upward and downward movement of the sheet stacker is suspended when the vertical door is detected to be opened.

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.

In a motor-driven slide type variable resistor, the tensioning of a toothed loop belt joined to an operating lever is adjusted with a pin adjusted to change the distance between a toothed pulley and a follower pulley in order to adjust a traveling speed of the operating lever. The variable resistor has little variations of the traveling speed of the operating lever and is accurate

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.

An encoder is connected to the drive system of the optical system of an image forming apparatus including an optical system for exposing a document image to a light and scanning the document image, a home position switch for detecting the optical system when it comes to the vicinity of the starting position, and a resist roller for setting the feeding start timing of a transfer sheet to the transfer section, and, on reproducing the above document image on a transfer sheet, when the pulse signals coming from the encoder, which are counted from the time when the optical system passes through the home position switch, reach the appointed value, the above resist roller operates.

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.

A novel D-amidase is described. The enzyme specifically hydrolyzes D-.alpha.-alanineamide into D-.alpha.-alanine. It is produced by culturing a microorganism belonging to the genus Arthrobacter, and is useful as an enzyme for efficiently producing D-.alpha.-alanine having a high optical purity and/or L-.alpha.-alanineamide from DL-.alpha.-alanineamide or D-.alpha.-alanineamide at low cost.

An electronic timepiece includes a primary timepiece circuit unit including a frequency supply for providing a relatively high frequency signal, a frequency converter responsive to the relatively high frequency signal to provide a relatively low frequency time unit signal, timing signals, and a plurality of word pulses indicative of a plurality of data words representing time data concerning the current time, and a set of additional data other than the time data, a timekeeping register arranged to store the time data and the additional data, and display elements for displaying the time data and the additional data. A secondary timepiece circuit unit includes a register arranged to store the additional data to be transferred to the timekeeping register.
