An original is allowed to pass on an exposing glass along a conveying path, thereby exposing and scanning a front surface of the original and reading an image by a CCD. A back surface of the original is subsequently fed to the exposing glass along a conveying path and is allowed to pass on the exposing glass, thereby exposing and scanning the back surface of the original. The image data read by the CCD is stored into an image buffer. The order of address columns to read out the image data on the front surface and the order of address columns to read out the image data of the back surface are made opposite. Thus, a copying apparatus which can efficiently expose and scan both of the front and back surfaces of a both-side original is provided.

An image processing apparatus for outputting image data in accordance with a designated output mode is constructed by an input unit to input the image data; a memory to store the image data inputted by the input unit; an output unit capable of outputting the image data stored in the memory in accordance with the output mode; a discrimination unit to discriminate a remaining capacity of the memory; and a change unit to change the output mode in the case where it is discriminated by the discrimination unit that the remaining capacity of the memory lacks. In the case where the designated output mode is a mode for discontinuously outputting the image data inputted continuously by the input unit by the output unit, the change unit changes the mode to continuously output the image data.

A recording apparatus is disclosed which comprises a recording head accessible to a variable recording position on a recording medium; a 7-segment display device to display the variable recording position accessed by the recording head; a detecting member for detecting operating conditions of the recording medium, for example, the presence of the recording medium and the inhibition from recording of the recording medium; and a control circuit for causing the display device to display information on a predetermined operating condition of the recording medium in lieu of the recording position accessed by the recording head when the predetermined operating condition is detected by the detecting means.
摘要:
A communication system for transmitting and receiving data serially, in which informations representing the operative positions of transmitters and receivers in two stations are passed through a single communication line, thus realizing a half-duplex communication.
摘要:
A recording apparatus capable of exchanging the recording medium includes a switch arranged to operate when the recording medium is exchanged, an electronic memory for storing the output of the switch in the electrical form, and a backup battery for supplying electrical power to the memory. Despite that the main electrical power source is cut off, the memory retains the storage of the fact of whether or not an event of exchanging the recording medium has ever occurred. After the position of the recording head has been re-adjusted, the memory is erased easily and quickly.
摘要:
An auto-focusing device having a photosensor unit for receiving luminous flux from an object. Lens drive data is predetermined and stored in a storage circuit. The stored lens drive data is selected in accordance with an output from said photosensor unit, and the lens is driven according to the selected data. Each lens drive data stored in the storage circuit is associated with a respective one of a plurality of outputs from the photosensor unit at a time when an object is disposed at a predetermined distance and when luminous flux from the object is actually received by the photosensor unit.
摘要:
A camera of the type having a camera body and a lens unit for detachable joinder therewith has data storage devices and processors in both the camera body and the lens unit, the processors being mutually compatibly programmed to enhance data communication between the camera body and the lens unit. The camera body processor is adapted to transmit commands to the lens unit processor and the latter is adapted to both confirm receipt of such commands and to provide indication of modifications of such commands based on lens unit capabilities. The camera body processor has companion capabilities for effecting photo-taking operations therein in respective diverse manners based on the nature of the lens unit output thereto in response to such commands.
摘要:
A stepping motor drive device including a comparator for comparing the number of drive steps with a prescribed value and a control circuit for changing the operation of the stepping motor between a 1-2 phase excitation drive mode and a 2-phase excitation drive mode based on the comparison result of the comparator.
摘要:
A power source system including a power source device and an external device connected to said power source device, in which the connection between the power source device with the external device is firstly confirmed, then the power is supplied from the power source device to the external device when a predetermined output of said power source device has been obtained, while a first signal is transmitted from said power source device to the external device connected thereto, and the supply of power is stopped if a predetermined signal is not fed from said external device.
