A developer replenishing apparatus includes a developer housing, a replenishing developer container accommodating a developer, an adapter to be mounted detachably on the replenishing developer container, and a tentative cap to be mounted detachably on an outlet portion of the adapter. The tentative cap has a top panel wall and a skirt wall formed so as to extend downwardly from the outer peripheral edge of the top panel wall. The skirt wall is composed of opposite side walls and a rear wall, and has an opening at its front part. A shielding plate covering the upper part of the developer housing is provided with a cap fitting portion and an adapter guide portion. On the shielding plate is mounted a sealing device adapted to cover the adapter guide portion and be caused to elastically open according to the movement of the adapter.

There is disclosed a printer with a reciprocating printing head for printing in both directions, capable of achieving satisfactory print precision without complicated positioning device. In case of printing certain particular information, if the printing head is moved to the corresponding print position in a particular direction, the printing head is moved further in the particular direction and is then returned to the corresponding print position.

A printing apparatus system includes a plurality of type units each having a plurality of type elements and each being different from the others. Each type unit may be mounted in the apparatus. A detector detects which of the type units is so mounted and produces a detection signal representative thereof. The printing pressure with which each type element is imprinted on a print medium is determined in accordance with the particular type wheel mounted in the apparatus as indicated by the detection signal. Additionally, the amount of advance of an ink ribbon for imprinting a type element on a type unit is determined in accordance with the particular type unit mounted in the apparatus, again as indicated by the detection signal.

A transferring apparatus transfers a toner image formed on the surface of a photoreceptor drum onto a sheet. The photoreceptor drum surface and a transfer roller are arranged in such manner that a gap larger than the thickness of the sheet is left between the photoreceptor drum and transfer roller, and a lower guide member for guiding the sheet in such direction that the sheet abuts the drum surface at a predetermined angle is arranged between a resist roller pair and the drum. The sheet which abuts the drum surface by way of the upper surface of the guide member is in close contact with the drum surface while being bent and deformed along the drum surface. A conveying roller is provided, opposite the upper surface of the lower guide member, with a predetermined gap between, at a position close to but out of contact with the drum surface. The conveying roller may also be arranged to contact the transfer roller.

An image forming apparatus has a low body and an upper body connected to the lower body rotatable about a pivot. The upper body carries an image forming device. The lower body carries a copy paper storage unit and a paper feeding device for feeding a copy paper sheet from the paper storage unit to the image forming device. The paper feeding device is provided with a paper inverting device between the paper storage unit and the image bearing device for inverting the copy paper sheet fed from the paper storage unit. The paper feeding device is exposed to the operator when the upper body is opened.

A key device includes a plurality of coils arranged on a printed board having an insertion hole along the longitudinal direction of the insertion hole. One of the plurality of coils is an electromagnetic induction generating coil connected to a power supply, and at least two of the remaining coils are key signal generating coils. In a key main body which can be inserted/removed into/from the insertion hole, a closed circuit is formed on a printed board. In the closed circuit, a plurality of coils and capacitors arranged between the plurality of coils are formed at positions opposite to the plurality of coils arranged along the longitudinal direction of the insertion hole. A bypass is formed in each of the coils arranged in the key main body, and a coil or coils for specifying a key type by switching operations of jumper line switching sections are selected. A key signal or key signals are generated from a key signal generating coil or key signal generating coils opposite to the selected coil or coils.
摘要:
A system and method for detecting occurrence of engine knock in internal combustion engines are disclosed which include: at least one engine knock sensor installed in an appropriate position at each engine cylinder, a band pass filter for passing a particular component of an output signal from an engine knock sensor, a rectifier for rectifying the particular component of the output signal passed through the band pass filter and an integrator for integrating the rectified signal with a variable interval. A device is also provided whereby engine driving conditions are detected, the integration interval being varied according to engine driving conditions so that no overlap of the integration interval of one cylinder with the ignition timing of another occurs. The integrated value derived by the integrator is corrected according to the variable interval, and the occurrence of knock in synchronization with the corrected integrated value is verified.
摘要:
In a printing apparatus address data accesses an address of a time table to vary an impact pressure and supplementary data of each typeface (or character) of a printing type wheel. Thse data are stored in various memories. Data input/output and its processing are controlled by a plurality of microprocessors connected to each other through an interface.
