    摘要: Disclosed a facsimile apparatus that combines copying with transmission. An external telephone is connected to it to be remotely controlled by a remote signal including at least one DTMF signal from the external telephone. And, there is provided means for comparing the tone duration of the tone-pair signal having DTMF frequencies sent by the external telephone with a predetermined detection time, and deciding whether or not said tone-pair signal is a valid DTMF signal used for remote signals based on the compared result. Further, there is provided means for estimating the tone duration of DTMF signals that is specific to the external telephone, and setting the optimum detection time.

    摘要: In an image processing apparatus or a method for expressing a halftone-including original image with binary black-and-white pixels and reproducing the original image in the form of a binary-coded output, the feature of the present invention resides in detecting, relative to each of the pixel units obtained by scanning and sampling the original image, a first average density level representative of the average density level of the pixel unit within a first specific reference pixel region composed of pixel unit groups adjacent to the subject pixel unit on the left and right. A second average density level represents of the average density level of the pixel unit within a second specific reference pixel region composed of a pixel unit group adjacent to the first specific reference pixel region from above. The density level of the subject pixel unit is detected in accordance with the first and second average density levels, thereby enabling correction of the gradation.

    摘要: To present a facsimile apparatus capable of preventing occurrence of unsuccessful transmission and enhancing the certainty of information transmission, the manipulating procedure in the manual reception mode for receiving a facsimile signal after an incoming telephone call is provided to the telephone user. When the manual receiving mode is set in the facsimile apparatus, after receipt of the incoming call by lifting the handset of the external telephone set in response to ringing of the calling side terminal device, a CNG signal is transmitted if the calling side is a facsimile apparatus set in an automatic transmitting mode. When this CNG signal is received, the voice signal for instructing the operating procedure for receiving the facsimile signal is delivered to the external telephone set. The operating procedure for receiving the facsimile signal is delivered through the handset, so that the facsimile signal may be easily received by a user not knowledgeable or familiar with the manipulation of the facsimile apparatus.

    摘要: A communications system connected to a telephone network includes a facsimile machine and a telephone set. The telephone set includes a telephone for conducting voice communications over the telephone network and a telephone answering machine for automatically responding to calls received by the telephone set over the telephone network. One or more operational parameters of the answering machine are set to define how it automatically responds to calls. A switch connects either the facsimile machine or the telephone set to a telephone network. One or more operational parameters of the answering machine is initially detected and stored. A controller controls the switch to connect either the facsimile machine or the telephone set to a telephone network based on a comparison of the stored parameter(s) and subsequently detected operational parameter(s) detected when the answering machine responds to a call.

    摘要: A facsimile apparatus is provided which can enhance the operability and usefulness of portable image reading devices when transmitting documents and which allows effective utilization of the image reading device. The facsimile apparatus includes a main unit and a separable handscanner between which image signals and various control signals are transmitted using an optical communication technique. A document is scanned by a handscanner that generates signals representing the document image. The image signals are temporarily stored in an image memory and transmitted to the main unit when necessary. Depending on the hook state of the telephone, the main unit either transmits the received image signals to a remote station or records the image on recording paper. When the main unit receives image signals over a telephone network, the received image signals are transmitted to the handscanner for storage into the image memory when necessary. This is done for example, when the so-called memory reception mode is set or when a recording section in the main unit is in a non-normal state.

    摘要: A facsimile system includes: a telephone apparatus; a facsimile receiving device for detecting a CNG (Calling Tone) signal, which follows a call request signal from a telephone exchange, on a telephone line, and receiving a facsimile data through the telephone line if the CNG signal is detected; a switching device for selectively connecting the telephone line to either the facsimile receiving device or the telephone apparatus; a device for controlling the switching device such that the switching device connects the telephone line to the telephone apparatus if the CNG signal is not detected by the facsimile receiving device while the telephone line is connected to the facsimile receiving device; and a device for generating a control signal if the CNG signal is not detected by the facsimile receiving device. The facsimile system also includes a pseudo-call requesting device connected to the generating device and the telephone apparatus for outputting a pseudo-call request signal, which is substantially same as the call request signal from the telephone exchange, to the telephone apparatus to make the telephone apparatus ringing when the control signal is inputted from the generating device.

    摘要: A facsimile machine including an automatic dialer requiring no dial operation when calling up a specific addressee particularly an addressee requiring frequent communication, allows simplified transmission of the addressee's dial signal to the service line by using "one-touch" key operation, thus achieving an extremely simplified procedure for transmitting written messages therethrough. The automatic dialer is provided with a memory storing dial data of such a specific addressee requiring frequent communications. In response to the operation of a specific instruction key on the operation panel, the automatic dialer reads dial data from memory before delivery to the dial pulse generator circuit, which then outputs the dial pulses to the service line to activate transmission of a message through a telecopier such as a facsimile.

    摘要: The disclosure is directed to an image recording arrangement for use in a facsimile equipment and the like, adapted to effect an image recording at rough density for standard information and an image recording at high density for fine information at a density at least two times that of the rough density. The recording arrangement includes a recording head having a dot density sufficient to resolve the high density so that, during the recording at the rough density, one bit of the recording information corresponds to at least two dots of the recording head.
