Abstract: An image recording apparatus includes a FAX unit (1) and a printer unit (2). The printer unit (2) has an ink-jet printing head (205), and records an image in accordance with image data received by the FAX unit (1). In this apparatus, when the power supply is turned on, the printer unit (2) performs a hard power-ON initialization process to initialize a watch-dog timer, registers, the work area of a RAM, and the like, and also initializes the RAM to erase data left in buffers. Thereafter, the printer unit transfers to a standby state. When a print request or a printer setting request is generated in the standby state, a soft power supply initialization process is executed to perform checking of the RAM, initialization of the work area, and initialization of carriage control and paper feed control, and the like. In the standby state, LEDs and the like of the printer unit are kept OFF. An operation error of the printer unit caused by remaining data can be prevented, and reliability of the apparatus can be improved. In addition, unnecessary power consumption can be prevented.

Abstract: PROBLEM TO BE SOLVED: To conduct error spread binarization processing in a short time without requiring a local memory by using a fast page mode so as to store and read error data generated in the error spread processing process to a register. SOLUTION: A contrast of consecutive 8-picture element C-J from input image data is read by registers X0-X7 by using the fast page mode. Furthermore, the contrast of B(C)-B(J) produced by the processing in a preceding line of the picture elements C J is read by registers E0-E7 by using the fast page mode similarly. Then the picture elements C are processed by using the value of the B(C) in the register E0, the contrast of the picture element C of a register X0, error data ER(A), (B) of an internal register of an error spread processing gate array caused by the processing result of the preceding picture elements A, B and the result is written in a register Y. Similarly, other picture elements D-J are processed and the error spread binarization processing is conducted in a short time without using a local memory.

Abstract: PURPOSE:To improve the operability and to simplify the processing by providing an exchange control function employing a cross point switch to a facsimile equipment being a master set. CONSTITUTION:A communication section 8 is provided with a detector 21 detecting a call signal from a line 9, a cross pint switch 22 switching the connection of facsimile equipments 10, 11 and the line 9 and a generator 23 generating a call signal. The slave facsimile equipments 10, 11 are respectively connected to the communication section 8 via the cross point switch 22 and connected to the communication line 9, the facsimile equipment main body and the other slave element by switching the cross point switch. Thus, plural facsimile equipments are used effectively with less number of lines than the number of installed facsimile equipments and convenience is improved.

Abstract: PURPOSE:To attain sure remote communication in the communication equipment implementing remote communication according to a remote command from other communication equipment by using one line selectively with other communication equipment (e.g. telephone set). CONSTITUTION:Interruption of a current of a DC loop formed by a telephone set and a line is detected by a current sensor 2. When a current interruption for 70ms or over is detected, a CML relay 1 is thrown from a telephone set (position a) to a MODEM (b) and a relay 5 is thrown from a position (d) to a position (c) to apply a DC voltage from a power supply 7 to the telephone set thereby forming a DC loop. When the current interruption within one sec is detected by the current sensor 2, the facsimile reception is transited.
