An image forming apparatus of an embodiment includes an image forming unit, a waste toner collection container, a paddle motor, and a controller. The controller acquires a replenishment amount for each toner cartridge, when the image forming component is replenished with the toner from the plurality of toner cartridges, sets a coefficient for each replenishment amount of the toner cartridges, at least one of each set coefficient is different from the others, each of the replenishment amount is corrected by each coefficient, and drives the paddle motor according to a cumulative amount of each corrected replenishment amount.

Image forming apparatus and control method for collecting waste toner in a waste toner collection container

An image forming apparatus of an embodiment includes an image forming unit, a waste toner collection container, a paddle motor, a memory unit, and a control unit. The image forming unit forms a toner image on a sheet using a toner replenished from a toner cartridge containing the toner. The waste toner collection container contains a waste toner generated in the image forming unit. The paddle motor rotates a stirring paddle provided in the waste toner collection container. The memory unit stores a coefficient for each type of toner. The control unit acquires a count value, which is a value related to a replenishment amount, corrects the count value with the coefficient corresponding to the type of toner, updates a cumulative count value with the corrected count value, and drives the paddle motor according to the updated cumulative count value.

A wireless network system includes a user device, a client and an access point. In the wireless network system, a wireless network mode of the client is started in an AdHoc mode in response to specific operation, a wireless network mode of the user device is switched to an AdHoc mode when it is detected that the wireless network mode of the client is started in the AdHoc mode. Then, infrastructure network information including a network name and an encryption key for setting the wireless network communication in the infrastructure mode is transmitted from the user device to the client, and the wireless network mode of the client is switched to the infrastructure mode on the basis of the infrastructure network information.

According to one embodiment, a toner supply device includes a motor and an estimating unit. The motor rotates a toner container that supplies a toner to an image forming apparatus. The estimating unit estimates a toner residual amount in the toner container at a second point in time on the basis of a total rotation time representing time in which the motor rotates in a period of use from a first point in time when the toner container is attached to the image forming apparatus to the second point in time.

An image forming apparatus includes an apparatus body which includes an attachment portion, a standby tray which is provided adjacent to the attachment portion of the apparatus body and stacks a paper thereon, a paper feeding tray stacks the paper thereon, a movement mechanism which moves the paper from the paper feeding tray located at the mounted position onto the standby tray along the paper conveying path, a holder member which moves to a first position so as to hold the paper at a predetermined position on the paper feeding tray and moves to a second position so as to recede from the paper conveying path, and a lock mechanism which engages with the holder member so as to hold the holder member at the first position when the paper feeding tray is located at the withdrawn position.

Image forming apparatus and control method thereof

An image forming apparatus according to the present invention includes: a first sheet feeding unit; a second sheet feeding unit provided adjacent to the first sheet feeding unit; one or plural first shutter(s) provided in the first sheet feeding unit; a driving unit that drives the first shutter(s); and one or plural second shutter(s) provided in the second sheet feeding unit, the second shutter(s) opening and closing in association with the opening and closing of the first shutter(s) driven by the driving unit. According to the present invention, when plural shutters for designating a stacking range of sheets are provided, an operation of any one of the shutters can be suitably associated with operations of the other shutters.

Upon receipt of an IR code from a remote controller, a peripheral device control apparatus generates, on the basis of peripheral device control information acquired from a server, a code for causing a peripheral device, which is an object of remote control by the control apparatus, to perform an operation as instructed by the received IR code, and then the control apparatus outputs the generated code as an IR code via an infrared ray generation section. In this way, the peripheral device control apparatus can readily control any one of a plurality of types of peripheral devices, in response to a user just giving an operation signal to a single input section.

Audio data which are read out from a compact disc drive are written into a hard disk drive () at a rate that is higher than an audio playback rate. The written audio data are read out at a rate which is higher than the audio playback rate, and than output to audio output interfaces (buffer memories). The audio output interfaces read out the audio data at the playback rate and output the data. Since the hard disk drive () can perform reading/writing at a rate which is sufficiently higher than the playback rate of audio data, monitoring is enabled while performing ripping.

When an emphasis setting of a next track is different from that of a current track, a silent signal having the emphasis setting of the next track written in its subcode information is output for a predetermined time prior to reproduction of the next track. The emphasis setting is changed for the next track while the silent signal is being output, so that the next track can be reproduced appropriately without involving an unwanted lack in its leading portion.

Method and apparatus for recording digital audio to compact disc from a mass storage device

When a write operation is to be performed for writing digital audio data (track), stored on a hard disk, to a CDR disk in an audio-digital-signal recording apparatus, control is performed, prior to execution of the write operation, such that the digital audio data stored on the hard disk can not be accessed by any other operation than the write operation, to thereby cause the other operation to regard the digital audio data as already erased from the storage section. After completion of the writing or copying of the digital audio data to the disk-shaped storage medium, the digital audio data are actually erased from the hard disk. Thus, even when power failure or shutdown occurs immediately after the copying of the digital audio data and before initiation of the audio data erasure from the hard disk, any operation, other than the write operation, can be prevented from accessing the digital audio data, so that the copyright on the digital audio data can be protected. As a result, the digital-audio-signal recording apparatus can prevent chain-like digital copying and thus can be properly used as consumer equipment.

The present invention provides an audio data recording medium reproducer, wherein CPUwhich writes audio data read by readerinto buffer memoryand buffer memory controllerwhich transfers the data to buffer memoryand inputs it into DACat a predetermined data rate are connected by a bus, and furthermore, CPUfor controlling a user interface is separately provided. Provision of a plurality of such simple controllers reduces costs to be lower than in the case of providing one high-performance controller. Furthermore, it also becomes possible to separately construct the respective functional parts as units.
