Problems solved by technology

[0005] However, even if the power consumption can be reduced, there is a limit to the transmission speed of SDIO. Therefore, if the frequency band of wireless LAN is very wide, the frequency band cannot be fully and effectively used, and the overall communication speed is not as fast as that using PCIe or The case of USB

Abstract

A wireless communication unit includes a low-speed communication IF and a high-speed communication IF. A controller includes a low-speed communication IF and a high-speed communication IF. The low-speed communication IFs are SDIO communication IFs and the high-speed communication IFs are USB communication IFs. The controller switches SDIO and USB according to a state of an image forming apparatus.

Description

technical field [0001] The present invention relates to an image forming apparatus that performs wireless communication with external equipment. Background technique [0002] An image forming apparatus is generally equipped with a wireless LAN function. As a method of installing a wireless LAN function, generally, a substrate called a wireless LAN module is prepared, and the substrate is communicably connected to a main controller of the image forming apparatus. There are various communication methods between the wireless LAN module and the main controller. For example, there are known high-speed peripheral component interconnection (PCIe, PCI (Peripheral Component Interconnect) Express), universal serial bus (USB, Universal Serial Bus), safe digital input and output (SDIO, Secure Digital Input / Output) communication methods, but these communication methods differ in communication speed and power consumption, and are used differently according to the purpose or application....
