Facsimile machine with facsimile data receiver and external computer

Transmission, speed at which data is transmitted over a digital transmission line between a transmission device and a remote device, is set by transmitting an inquiry command to the remote device at a predetermined transmission speed; receiving, from the remote device, a response to the inquiry command; determining based on the content of the response any transmission speeds common between the remote device and the transmission device; and setting transmission speed at which transmission between the transmission device and a remote device is to be performed to one of the transmission speeds common between the remote device and the transmission device.

Method and device for setting speed of data transmission

A facsimile machine including a first facsimile-data transmitter and/or a first facsimile-data receiver, a first telephone set, a data receiver including a connector connectable to an external computer for receiving, from the computer, designating data designating a second telephone set, and a calling device which calls the second telephone set designated by the designating data, so as to connect the first telephone set to the second telephone set via a communication line.

Facsimile machine

A facsimile machine including a first facsimile-data receiver including a connector connectable to an external computer for receiving, from the computer, facsimile data including image data representing an image, and receiver-designating data designating a second facsimile-data receiver to which the facsimile data are transmitted, a facsimile-data transmitter which transmits the facsimile data to the second facsimile-data receiver designated by the receiver-designating data, a recorder which records, on a recording medium, the image represented by the image data of the facsimile data, a memory which stores self-designating data designating the first facsimile-data receiver, the receiver-designating data and the self-designating data being of same kind of data as each other, so that the receiver-designating data are comparable with the self-designating data, and a control device which controls the recorder to record the image represented by the image data when the receiver-designating data are identical with the self-designating data, and does not control the recorder to record the image when the receiver-designating data are not identical with the self-designating data.

Facsimile machine connectable to an external computer

A request command is transmitted from a computing device to a facsimile device to request function list data of the facsimile device, representing adjustable functions, possible function settings, and/or current function settings of the facsimile device. The facsimile device receives the request command and responds by sending a description of its functions, corresponding possible function settings, and/or current function settings as function list data to the computing device. The function list data and settings are displayed at the computing device when a remote setup routine is executed, and a user can identify the functions and function setting options of the connected facsimile, and set function settings by an input device. The computing device sends the desired function settings to the facsimile device, and the facsimile device changes its function settings according to those received.

Facsimile system and method for controlling facsimile system

In this facsimile machine, it is determined whether data to be stored in a RAM is image data, and, if the data is image data, a normal cluster for writing the image data into is ensured. If the data is not image data, a defective cluster is selected, and the data is written into the defective cluster. In this case, if no defective cluster is selected, a normal cluster is selected, and the data is written into the normal cluster. Upon termination of the data writing operation, the data is managed on a classification (kind) basis. Accordingly, a facsimile machine is provided that is low in price and can easily carry out individual management for preservation of data while maintaining preservation (storage) quality of data even when a semiconductor memory that is not guaranteed in quality is used as the storage medium for the data.

An image recording apparatus which records an image of an original document on an image receiving sheet with the use of a photosensitive recording medium, the image receiving sheet having front and rear faces differing in reflection ratio. To detect error in sheet face orientation, a sheet face sensor unit is provided upstream of a pressure developing unit which discriminates a face of the image receiving sheet. The sensor unit includes a light emitting element for emitting light toward the face of the image receiving sheet and a light receiving element for receiving light emitted from the light emitting element and reflected on the face of the image receiving sheet. A central processing unit is supplied with data representative of amounts of light emitted from the light emitting element and light received at the light receiving element, wherein the central processing unit computes a reflection ratio based on the data supplied thereto and produces a discrimination signal indicative of an error in sheet face orientation of the image receiving sheet based on the reflection ratio being computed.

Image recording apparatus having front/rear sheet face sensor

In a pressure developing device employed in an imaging device like a duplicating machine, an optical printer etc., pressure force for evenly pressurizing a recording medium is capable of being varied in accordance with the width of the recording medium to be pressurized.

Pressure developing device

An image recording apparatus adapted to record an image on an image receiving sheet selected from plural kinds of sheets using a photosensitive recording medium, wherein the photosensitive recording medium is exposed to light emitted from an exposure lamp to form a latent image thereon. In view of the fact that a photosensitivity of the recording medium varies depending upon ambient temperature and/or humidity, at least the ambient temperature is detected so that an exposure amount applied to the photosensitive recording medium is controlled in response to the sensed temperature and the kind of the sheet on which the image is formed.
