Embodiment Construction

[0040] Preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0041] figure 1 It is a cross-sectional view showing the structure of the multifunction peripheral 1 according to one embodiment of the present invention. In this digital multifunction machine 1, it is possible to selectively perform: a copy mode in which an image of an original document is read and printed on recording paper; an image of an original document is read and transmitted, or an image of an original document is received and printed on recording paper and a print mode for printing images received from an information terminal device via a network onto recording paper, etc. The multifunction peripheral 1 generally includes a document conveyance and reading unit 2 , an image forming unit 3 , a paper feeding unit 4 , and a paper output processing unit 5 according to its structure.

[0042] Next, the operation of the digital multifunctio...

Abstract

There are provided an information processing apparatus capable of reducing power consumption more than ever without deteriorating processing efficiency in the apparatus as a whole, an image forming apparatus, and a method for controlling the information processing apparatus. When the operation mode is in a sleep mode or an energy save mode at the time of receiving a facsimile data by a FAX modem, an instruction is made not to an image processing chip but to an IO chip to perform image processing for the received facsimile data. The IO chip performs the image professing using an LCDC (Liquid Crystal Display Controller). During this time, main control sections such as an SoC is remained in the non-energized state.

Description

technical field [0001] The present invention relates to an information processing device, an image forming device, and a control method for the information processing device. Background technique [0002] The power consumption of multifunctional machines that have the functions of copiers and printers has also increased with the progress of higher functions, and it is possible to supply power to only the minimum structure according to the use status, and to stop power supply to most of the so-called It operates in the energy-saving (hereinafter referred to as "energy-saving") mode. [0003] In addition, for data communication, the MFP also has an interface for connecting to a network. Such an interface is often provided on a sub-board called a NIC (Network Interface Card), and many components such as a CPU (Central Processing Unit) for overall device control are provided on a main board. [0004] In a multifunction peripheral operating in the power saving mode, for example...
