摘要:
An image forming apparatus includes an electrostatic latent image carrier carrying an electrostatic latent image and a development unit that develops the electrostatic latent image. The development unit includes a developer carrier, first, second, and third developer conveyers, and an opening area. The developer carrier is disposed opposing to the electrostatic latent image carrier. The first developer conveyer supplies a developer to the developer carrier. The second developer conveyer conveys the developer, and transports the developer to the first developer conveyer at a downstream side of the second developer conveyer. The third developer conveyer collects the developer, conveys the developer, and transports the developer to the second developer conveyer in a downstream side of the third developer conveyer. The opening area, disposed higher than a lowermost point of the first developer conveyer, allows the developer to drop from the first developer conveyer to the second developer conveyer.

In a multiple type air conditioner system which includes a plurality of outdoor units and a plurality of indoor units, the plurality of outdoor units are connected with the plurality of indoor units through a communication line, address setting is attained by generating a random address from each of all the indoor units under a command of one of the outdoor units and generating a dummy address from each outdoor unit on the basis of the random address, by obtaining a correlative relationship between the outdoor and indoor units on the basis of a variation of a physical quantity of the outdoor unit connected to the indoor unit actually operated based on the dummy address, and by updating the addresses of all the outdoor and indoor units on the basis of the correlative relationships between all the outdoor and indoor units obtained through the step.

The subscriber line interface circuit comprises subscriber nodes, reception nodes and transmission nodes, a power feeding unit, adders, impedance elements, an inverting amplifier, and a feedback element. The subscriber nodes are coupled to a subscriber terminal via a subscriber line, and the reception and transmission nodes are coupled to an exchange via a reception line and a transmission line, respectively. The feeding unit supplied a DC current to the terminal and controls the current. The first adder adds the voltage between the subscriber nodes and the voltage from the reception node. The first impedance element has an impedance corresponding to a real-number multiplication of the impedance between the subscriber nodes, and is applied with the output voltage of the first adder. The amplifier is given with the output of the first impedance element. The second impedance element, inserted in the feedback path of the amplifier, has an impedance corresponding to a real-number multiplication of the impedances of the subscriber line and the terminal. The feedback element supplies, to the feeding unit, a signal corresponding to the current flowing through the first impedance element as a control signal. The second adder adds the output voltage of the amplifier, the output voltage of the first adder and the voltage of the reception nodes, and supplies the resultant signal to the transmission nodes.

A liquid supplying device includes a pump, an operation member, an entry channel, and a shutter. The pump includes a deformable liquid container to store liquid and is configured to suck liquid from a liquid storage unit to the liquid container by increasing volume of the liquid container and supply the liquid from the liquid container to a liquid supply target by decreasing the volume of the liquid container. The operation member is operated by a user. The entry channel connects the liquid storage unit and the liquid container. The shutter moves with movement of the operation member to shut the entry channel.

An image forming apparatus includes a media roll, art image forming device, and a feeder. In the media roll, a printing medium having an adhesive face is wound in a roll shape. The image forming device forms an image on the printing medium. The feeder feeds the printing medium. The feeder includes a protection belt and a pair of rotary bodies. The protection belt presses against and protects the adhesive face of the printing medium. The pair of rotary bodies sandwich and press the printing medium and the protection belt between the pair of rotary bodies. An approach angle of the printing medium is within a range from 0° to 30° and is formed by the printing medium drawn from the media roll and approaching to between the pair of rotary bodies and an opposing face of the protection belt opposing the image forming device.

The card connector, into which an IC card having a plurality of pads arranged in parallel at front and back positions is inserted, includes a plurality of contacts each contacting a corresponding one of the plurality of pads of the IC card and a base member that supports the plurality of contacts. Each of the plurality of contacts has a first and a second elastic piece each having a contact point portion that electrically contacts a pad of the IC card. The first and second elastic pieces are formed such that contact pressures of the respective contact point portions against the pads are different from each other. The plurality of contacts is arranged on the base member in parallel at front and back positions and a first and a second contact piece are arranged in an opposite manner in contacts aligned linearly at front and back positions.

A developing unit includes a developer carrying member, a supplying compartment, a recovery compartment, and an agitation compartment. The developer carrying member develops a latent image formed on an image carrier with a two-component developer. The supplying compartment has a developer supplying transporter to supply the two-component developer to the developer carrying member while transporting the two-component developer. The recovery compartment has a developer recovery transporter to transport the two-component developer recovered from the developer carrying member. The agitation compartment has a developer agitation transporter to agitatingly transports developer. The developer agitation transporter includes a first screw having a screw pitch to transport developer to an upstream end of the supplying compartment from a downstream end of the agitation compartment. The developer supplying transporter includes a second screw having a given screw pitch, which is greater than a screw pitch of the first screw.
