摘要:
An image reading apparatus capable of reading documents includes a reading unit including a light emitting element, a mechanism configured to move the reading unit, and a control unit configured to control the reading unit and the mechanism both to carry out reading by turning on the light emitting element and moving the reading unit and to temporarily stop moving the reading unit upon occurrence of a predetermined factor. The control unit sets a first current value which is caused to flow through the light emitting element when reading is carried out and sets a second current value which is less than the first current value and which is caused to flow through the light emitting element when the reading unit is temporarily stopped.

A recording apparatus includes a recording unit for ejecting an ink to a recording member, a detection unit for detecting a remaining amount of ink, a memory for storing received data, and a control unit for controlling an operation of the recording unit to record an image in accordance with the received data, and controlling the memory to store image data in the memory. The control unit controls the memory in accordance with an output from the detection unit upon completion of recording of a predetermined volume of data, clears data stored in the memory when the output from the detection unit indicates a presence of ink, and preserves data stored in the memory when the output from the detection unit indicates an absence of ink.
摘要:
An image communication system equipped with an ink jet printer having multiple ink orifices permits excellent images without ink stains. The system includes a heat fusing device actuated in accordance with reception of a call signal, and image data is received after the temperature of the heat fusing device has reached to a predetermined temperature. If the predetermined temperature is not attained within a predetermined time, an error alarm is output.
摘要:
An existing printer arranged to print data from a PC (personal computer) is used as the printer unit of a facsimile apparatus. The PC uses a printer driver dedicated to an existing printer (capable of performing the same processing as the printer unit of the facsimile apparatus) as a module, serving as application software for a facsimile-apparatus control unit, for printing the data from the PC. When printing data from the PC, a command uniquely directed to the facsimile apparatus is added to the printing data generated by the PC's printer driver, and the resultant data is transmitted to the facsimile apparatus. Upon receipt of the transmitted data, the facsimile apparatus removes the added command, thus restoring the printing data generated by the printer driver, and transmits the restored data to the printer unit to perform printing. It is thus possible to use the printer unit and the printer driver which utilize existing printers, and to cause the facsimile apparatus to wait in a state of receiving a common command system.

An image reading apparatus includes a carrying unit for carrying a sheet original and a book original to a reading position, an original urging member including a reference member, closed when a sheet original is carried by the carrying unit and opened when a book original is carried by the carrying member, a reading unit for reading an image of an original carried to the reading position and the reference member of the original urging member in a closed state, and a correcting unit for correcting nonuniformity of an image signal obtained by reading an original image on the basis of a reference signal obtained by reading the reference number. When the original urging member is open, the correcting unit corrects nonuniformity of an image signal on the basis of the reference signal used upon reading of a previous original image.
摘要:
A facsimile apparatus employs an ink jet printer in which the ink discharge recovery operation by idle ink discharge from all the discharge openings of the recording head is conducted at a suitable timing instructed by a central processing unit. The timing of the idle ink discharge is determined not by a timer interruption procedure, which imposes an additional burden on the processing capacity of the central processing unit, but from the image data receiving rate and the amount of actually received data. In this manner the central processing unit can provide increased processing capacity, and the control program can be simplified and made less expensive.
摘要:
A peripheral unit is controlled by means of a driver in another apparatus, where an instruction sent to the peripheral unit contains both data produced by the driver and data produced by another application in the other apparatus. This is done by subjecting the instruction received from the other apparatus to processing in which the data produced by the other application is deleted.
摘要:
A drive control system for a stepping motor which stores values for the current driving each phase of the motor in data tables. A central processing unit drives the motor in accordance with the current values stored in the data tables. The current values are stored in the data table with corresponding addresses. The current values are read out sequentially from the addresses in the data tables. Each time the address is incremented by 1, the magnitude of the angle of rotation of the motor is set so that it is always the same.
摘要:
An ink jet recording apparatus which records on a recording medium by discharging ink on a recording medium. The ink jet recording apparatus comprises an ink jet recording head which discharges ink to record on a recording medium, a conveyance route which leads the recording medium in the exhaust direction passing above the recording head, and a cap which covers the discharge ports of the recording head provided below the ink jet recording head.
