Abstract: Provided is a touch-panel-integrated display device that, even in a case where it is caused to operate in the wake-up mode, flicker does not occur when the device returns from the sleep state. The touch-panel-integrated display device includes a plurality of electrodes provided in the display area, and a plurality of lines that are connected with the electrodes, wherein a touch scan signal is supplied to the plurality of lines, and a touch operation is detected based on changes in capacitances of the electrodes. When a predetermined time has elapsed since the last time a touch operation was detected, an operation state is shifted to a sleep state in which updating of display in the display panel is stopped. When a touch operation is detected by a detection circuit in the sleep state, the updating of the display in the display panel is resumed.

Abstract: 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.

Abstract: A facsimile apparatus and a telephone set are connected to one telephone line in parallel with each other. A voltage variation .DELTA.V caused by closing and opening of a DC circuit of the telephone set is detected via an off-hook detector of the facsimile apparatus to establish the operation mode of the telephone set. The detected operation mode of the telephone set is stored in a RAM. The detected mode of the telephone set, and thus the closing and opening of the DC circuit of the telephone set, is displayed and/or printed.

Abstract: A facsimile apparatus capable of conserving the recording paper and using a limited amount of the recording paper effectively is disclosed. In the case where what is called the total blank line data with the entire line representing blank (data zero) data at the time of receiving are successively received are received successively, the subsequent successively-received total blank line data are not printed by the recorder on the recording paper. The recording paper is thus printed omitting the unrequited marginal portion, and therefore a limited amount of recording paper is used effectively without adversely affecting the effective image data.

Abstract: 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.

Abstract: A facsimile apparatus (1) is provided with a function of making a facsimile communication through a telephone line (2). The facsimile apparatus includes: a memory device (8) for storing information to indicate a condition related to the facsimile communication; a voice data storing device (15) for storing predetermined various kinds of voice data; a speech signal synthesizing device (16) for synthesizing a speech signal on a basis of the stored information and the stored voice data; and a transmitting device (3) for transmitting the synthesized speech signal onto the telephone line (FIG. 1).

Abstract: Here is disclosed a printer which, in an image mode of a standard resolution, decodes encoded image data of one line and executes printing on recording paper (22) twice based on the decoded image data. This printer can be applied to a facsimile apparatus. Such a printer comprises a detector (12) which detects whether the decoding has been completed up to the midpoint of each line. At the same time that the decoding of one line is started, a first printing is started based on other already decoded data, and at the same time that the completion of decoding up to the midpoint is detected, a second printing is started. Each time the first or the second printing is completed, the recording paper (22) is conveyed by a pulse motor (18) by a predetermined amount by the beginning of the subsequent printing. Therefore, irregularities in the printing operation and conveyed amount of the recording paper (22) can be diminished.

Abstract: When a number of exothermic elements arranged linearly are used for printing, driving data are inputted to the gate circuits of each exothermic element, and the gate circuits are controlled by the strobe signals in the conducting/nonconducting state. The circuit gates are divided into groups and the strobe signals different for each group are inputted in sequence. At printing, when there is the group having a relatively small number or no exothermic elements being heated and driven, and the strobe signal is given to each group successively for any groups, the necessary driving time may be wasted. The operating speed many be improved if a plurality of strobe signals are outputted in parallel when the number of exothermic elements being heated and driven is relatively small, and if the corresponding strobe signals are stopped when there is no exothermic element, and outputting the next strobe signals immediately in both cases.

Abstract: A group III facsimile apparatus is provided with a detachable image reading unit for hand held scanning of large or bulky originals. Lines of image data from the image reading unit are stored in a memory, and then read out and converted to modified Huffman (MH) running length code for transmission. Fill bits are added where necessary so that each line has a minimum transmission time of 10 milliseconds. A group III facsimile apparatus normally automatically disconnects from a transmission when no data has been transmitted for five seconds. To keep this from happening while an original is being scanned slowly by hand, enough fill bits are added to make each line a minimum transmission time of one second when the number of lines of image data in the memory is less than 10.

Abstract: An image data transmission apparatus, which may be used as a facsimile apparatus, includes an image data reader which is detachably connected to the main body. The reader can read image data from an original fed past the reader, or it can be detached and used to scan an original. A device exists within the apparatus, which detects the mounting or unmounting of the reader, and if it is detected to be unmounted and not being used, power will be shut off. Further, a device exists, within the apparatus, which, when the reader is detected as mounted, will print read data. Also, when the reader is detected as unmounted, read data will be stored in memory. Thus, a speedy and power efficient image data transmission apparatus has been created.

Abstract: In a facsimile circuit monitor system, a control signal to be transmitted or received is initially converted into an easily stored code to be stored in a memory. When a certain signal has been received, a signal level is calculated on the basis of actual gain of an AGC (automatic gain control) and stored in the memory so that information stored in the memory may be outputted.
