The present invention enables connections of electronic components of an electronic apparatus to be inspected easily and reliably. To accomplish this, an electronic apparatus including a plurality of electronic components, includes a control circuit which controls input and output of an electric signal to and from the plurality of electronic components and a plurality of inspection circuits which inspect connections of the plurality of electronic components. The plurality of inspection circuits are connected in series, the control circuit is connected to an end of the series, inspection signals output from the plurality of inspection circuits are superimposed on one another in sequence into an signal and the signal is input into the control circuit, and determination is made at the control circuit as to whether each of the plurality of electronic components is connected properly or not.

Electronic apparatus and control method thereof

An image processing system for enabling a manufacturer's image forming apparatuses to be used as far as possible by a user. Design is made to enable a manufacturer or a vendor to appeal the predominance, particularly economy, of their own image forming apparatuses by the utilization of a user interface for controlling a recording process.

Image processing system, method of controlling the image processing system and control program for the image processing system

A pattern register stores an excitation pattern of stepping motors. A first pattern control unit reads out an excitation pattern for n bits from a predetermined address of a pattern register for supplying the same to an external motor driver. A second pattern control unit reads out an excitation pattern for the same n bits as in the first pattern control unit from a predetermined address of the pastern register and supplies the same to an external motor driver. An output control unit selectively outputs a first output mode for using the first pattern control means and the second pattern control means independently, or a second output mode for using them in an interlocked manner.

Control device for stepping motor

An apparatus for executing a printing process on the basis of a print job from an external apparatus, comprises a post-processing unit which can apply post-processing for printed paper sheets using paper sheets prepared independently of the printed paper sheets; a detector for detecting in the post-processing means that the paper sheets prepared independently of the printed paper sheets are set; determination means for determining whether or not print start trigger information is attached to the print job, which indicates an instruction to start printing in response to trigger information to start printing; and print control means for, (i) when a print job designated with the post-processing by the post-processing unit is received and it is determined that the print start trigger information is attached to the received print job, delaying a process of the print job until the detector detects that the paper sheets are set, and starting execution of the print job when the detector detects that the paper sheets are set, (ii) and when a print job designated with the post-processing by the post-processing unit is received and it is determined that the print start trigger information is not attached to the received print job, starting the received print job independently of a detection by the detector.

Printing apparatus, information processing apparatus, and printing system

In a transmitting apparatusthere are provided PLL circuitfor generating high-speed clock signals up to 2times (m being a positive integer) from a basic clock signal, and a clock generating circuitfor generating a communication clock signal (S-CLOCK) and a reception timing signal (S-LATCH*) as independent clocks of any time length with using the generated high-speed clock signal as the smallest unit.

Data transmitting unit, data communicating apparatus and data communicating method

On the basis of information obtained from an IC card and concerning the physical features of a user, it is judged whether or not the user is a handicapped person. When it is judged that the user is a handicapped person, a fixed sheet supply source is not displayed on an LCD of an operation panel. When the user is a handicapped person, therefore, it is possible to inhibit sheet feeding from the fixed sheet supply source, from which it is difficult to remove a jammed sheet.

Image forming apparatus that obtains user information

An image processing apparatus is provided which comprises an image reading section for reading an original document by causing an image reading head of the image reading section to move relative to an original document; an image recording section for recording an image on a recording medium in accordance with an image signal; a power source for supplying power to the image reading section and the image recording section; and a control device for controlling the speed of movement of the image reading head according to an operating state of the image recording section. The image processing apparatus of the invention overcomes problems associated with the use of prior art image forming apparatus, such as multi-function copying machines, that include an image reading section and an image recording section, and which require the use of large-capacity power sources for supporting the electrical loads of various components that may be operating simultaneously within the individual apparatuses.

Image processing apparatus and method of controlling the same

An image processing apparatus comprises: an inserting unit to insert a memory medium such as IC card or floppy disc which can be freely attached or detached and in which programs to control the image processing apparatus have been stored; a memory to store the program which has been read out from the memory medium and kind data indicative of the kind of program; a loading circuit to load the program stored in the memory medium into the memory; and a control unit to control the image processing apparatus in accordance with the program stored in the memory. In the case where the program has already been stored in the memory, the control unit controls the loading circuit in a manner such that when the kind data stored in the memory is the data indicative of a special program, the loading of the program from the memory medium to the memory is inhibited and, when the kind data stored in the memory is not the data indicative of the special program, the loading of the program from the memory medium to the memory is executed.

Image processing apparatus which can update program

A method of managing an image forming apparatus by a remote computer comprises the steps of detecting an abnormal state in the image forming apparatus, transferring an error code corresponding to the kind of the detected abnormal state to the computer, selecting a predetermined program according to the transferred error code by the computer, transferring the selected predetermined program to the image forming apparatus by the computer, and executing the transferred predetermined program by the image forming apparatus. The predetermined program is a diagnosing program to examine the causes of a failure in the image forming apparatus.
