An electrostatic recording apparatus includes a developing agent carrier member provided to extend along a predetermined path. A developing agent convey unit conveys a developing agent along the surface of the developing agent carrier member. The developing agent carrier member has a step in a developing agent convey direction of its surface. A plurality of recording electrodes are aligned on an upper surface of the step of the developing agent carrier member and spaced apart from each other with gaps therebetween in a direction perpendicular to the developing agent convey direction, and project uniformly from the step. An opposite electrode is disposed to oppose the plurality of recording electrodes. A leaf spring member supports at least portions of the plurality of recording electrodes projecting from the step and can swing the projecting recording electrodes in directions to approach to and to separate from the opposite electrode. A voltage applying unit applies recording voltages to the plurality of recording electrodes in accordance with recording data to selectively transfer the developing agent conveyed along the surface of the developing agent carrier member to the opposite electrode.

Electrostatic recording apparatus capable of maintaining constant gap

An electrostatic recording apparatus includes a developing agent carrying member having a surface for carrying a developing agent thereon. A plurality of recording electrodes are arranged on the surface of the developing agent carrying member in parallel to each other at a predetermined gap while being electrically insulated from each other. An electrode cylinder is arranged to oppose the plurality of recording electrodes at a predetermined gap. A developing agent convey section conveys the developing agent such that a circulating convey path is formed along the surface of the developing agent carrying member. A voltage control section outputs a control signal including recording data. A recording electrode drive section is provided inside a space defined by the circulating convey path. Upon reception of the control signal from the voltage control section, the recording electrode drive section applies a recording voltage to the plurality of recording electrodes in accordance with the recording data, and selectively transfers the developing agent conveyed by the developing agent convey section to the electrode cylinder, thereby forming a recording image.

An electrostatic recording apparatus includes a magnet roll for conveying a developing agent along a predetermined developing agent convey path. A plurality of recording electrodes are arranged to oppose the magnet roll and along the developing agent convey path. An opposite electrode has a portion opposing the plurality of recording electrodes and is arranged with a predetermined gap from the plurality of recording electrodes. A voltage applying unit applies a recording voltage corresponding to supplied dot recording information to each of the plurality of recording electrodes to generate a transferring electric field for transferring the developing agent to the opposite electrode between the opposite electrode and the plurality of recording electrodes, thereby forming a dot recording image corresponding to the dot recording information on the opposite electrode. The voltage applying unit applies, between the plurality of recording electrodes and the opposite electrode, a recovering electric field for recovering a part of the developing agent transferred on the opposite electrode to the plurality of recording electrodes within one-dot recording period in which one dot of the dot recording information is recorded in the conveying direction of the developing agent.

An electrostatic recording apparatus includes a developing agent carrier member arranged along a predetermined developing agent convey path. A developing agent conveying section conveys a developing agent along a surface of the developing agent carrier member. A plurality of recording electrodes are arranged on the surface of the developing agent carrier member at a predetermined pitch. An opposite electrode is arranged to oppose the plurality of recording electrodes at a predetermined gap. A voltage applying section applies a voltage corresponding to recording information to each of the plurality of recording electrodes to selectively transfer the developing agent, which is conveyed along the surface of the developing agent carrier member, to the opposite electrode. The developing agent carrier member has a step at a portion on its surface shifted to an upstream side of a developing agent convey direction from a position closest to the opposite electrode. At least distal end portions of the plurality of recording electrodes project from this step toward the closest position to form projections. The projections are swingable in a direction of approaching or going away from the opposite electrode.

In an intelligent card, a keyboard has numeric keys for entering identification information and a collation execution key. A solar cell, a display device and an IC chip for performing arithmetic operations and card identification are incorporated in a case. The IC chip includes a nonvolatile memory for storing predetermined identification information. The predetermined identification information is compared with the input identification information entered at the keyboard upon operation of the key, thereby performing card identification.

An apparatus for detecting the stop of a magnetic tape traveling in a magnetic recording and reproducing device which carries out a plurality of functional modes and in which the magnetic tape travels at a speed corresponding to a selected functional mode, wherein a pulse generator produces one pulse per rotation of a magnetic tape-driving section. A time interval between the respective pulses issued from said pulse generator is determined from a number of reference pulses having a reference frequency which are delivered from a reference pulse generator and are later counted by a counter. A longer traveling time of a magnetic tape than that specified for the different functional modes is preset in a numeral code generator in the form of a numeral code. When the traveling time of a magnetic tape is found to be longer than that present for a selected functional mode, a detection signal based on an output count from the counter is issued to judge whether the magnetic tape has ceased to run.

A synchronous control apparatus in a multi-circuit system is provided with a first circuit which operates receiving a constant power supply and a second circuit which operates receiving a power supply at need, with a plurality of operation modes. The operation mode of the first or second circuit is selected by a mode selection circuit. When the mode selection circuit selects another operation mode, a synchronous control circuit provided in the first circuit transfers an initializing signal in synchronism with the first circuit to the second circuit. The second circuit is initialized in synchronism with the first circuit.
