A sheet conveyance apparatus configured to convey a sheet includes a casing, a belt unit, an accommodating unit, a moving unit, and a rotary member. The accommodating unit and the belt unit move to a first state, a second state, and a third state. In the first state, the accommodating unit is positioned at a closed position and the belt unit is positioned at a first position to convey the sheet by a conveyance belt. In the second state, the accommodating unit is positioned at an opening position and the belt unit is positioned at the first position to open a sheet conveyance path. In the third state, the accommodating unit is positioned at the opening position and the belt unit is positioned at a second position to allow the conveyance belt to attach to and detach from the belt unit.

Sheet conveyance apparatus and image forming apparatus

When a developing device including a developer carrying member, a regulating blade, and a developing device frame including first and second ribs is seen in a cross section perpendicular to a rotational axis of the developer carrying member, the first and second ribs are provided at a predetermined gap in a direction from a position where the regulating blade is closest to the developer carrying member toward a rotation center of the developer carrying member. The first and second ribs have first and second supporting surfaces, respectively, each supporting the regulating blade and having a width of 3.0 mm or less. In a state that the regulating blade is supported by the first and second supporting surfaces, the regulating blade is fixed to the mounting portion in a region of the regulating blade corresponding to a maximum image region of an image bearing member.

Provided is an information processing system that identifies communication terminal identification information of a portable communication terminal used by a user when the user uses communication through an access point. An information processing system includes a communication terminal identification information storage unit that stores the communication terminal identification information of the portable communication terminal that performs communication using the wireless communication device, a person identifying information comparison processing unit that determines whether there is a same person using at least two or more pieces of person identifying information acquired in a person identifying information acquisition device in a certain wireless LAN communication spot where the wireless communication device exists, and a communication terminal identification information narrowing-down processing unit that performs, from the communication terminal identification information storage unit, processing for narrowing down the communication terminal identification information of the portable communication terminal of the user who performs communication using the wireless communication device, by extracting pieces of communication terminal identification information corresponding to the respective pieces of person identifying information from the communication terminal identification information storage unit, and identifying common communication terminal identification information, when existence of the same person is determined as a result of the determination.

Information processing system

A communication terminal identification information identifying processing system includes a person recognition processing unit that performs person recognition processing based on image information obtained by capturing a wireless LAN communication spot by a capturing device, a communication terminal identification information acquisition processing unit that acquires communication terminal identification information, a communication terminal identification information storage unit that stores, for each person, candidate communication terminal identification information of the portable communication terminal used by the person, a communication terminal identification information comparison processing unit that compares the candidate communication terminal identification information of the portable communication terminal stored in the communication terminal identification information storage unit and the communication terminal identification information acquired in the communication terminal identification information acquisition processing unit, and generates new candidate communication terminal identification information, and an output processing unit that outputs a part or all of the candidate communication terminal identification information.
