  • Patent number: 9141067
    Abstract: An image forming apparatus that is capable of using a residual sheet effectively even in a double-sided printing mode. A control unit controls to perform a double-sided image formation process to recording sheets. A detection unit detects a jam of the recording sheet. A determination unit determines whether residual sheets, which are recording sheets on the conveyance path other than a jamming sheet that generates a jam, are available in the image forming process resumed after the jam is removed based on the number of copies of sheets on which the same image is formed, the recording sheets on which images have been formed on one sides, and the latest recording sheet that was normally ejected. The control unit stops the process and ejects the residual sheets that are determined unavailable from the conveyance path when a jam is detected during the process.

  • Patent number: 9104163
    Abstract: Provided is an image forming apparatus capable of executing a plurality of kinds of binding process in one job. A printer control section transmits, to a finisher, a job for equal to or larger than a total number of copies being a sum of a first number of copies for performing the binding process by using a staple and a second number of copies for performing the binding process without use of the staple. On the finisher side, in accordance with the job, a finisher control section causes a stapler to perform a stapling process for the first number of copies and an eco-stapler to perform an eco-stapling process for the second number of copies.

  • Patent number: 8582126
    Abstract: A design support method of verifying control on a device of an image forming apparatus registers, in a storage device, trigger information for specifying a content of control to be executed when a start condition for switching the control state of the device is satisfied (S1002). The apparatus then registers, in the storage device, the allowable range of the state change of the device due to control switched when the start condition is satisfied (S1003). The apparatus then verifies whether the state change of the device due to the control switched when the start condition is satisfied falls outside the allowable range, by referring to the operation state of the device which is input through an input unit, and the trigger information registered in the storage device (S1004).

  • Publication number: 20120248678
    Abstract: A sheet conveying device which makes it possible to facilitate separation of multi-fed sheets. A separation pad and a separation roller separate sheets from a sheet bundle placed on a sheet tray, on a one-by-one basis. A pull-off roller section formed by a pair of conveying rollers nips and conveys a fed sheet. The two conveying rollers of the pull-off roller section have rotational axes extending in respective different directions. A registration roller further conveys the sheet conveyed by the pull-off roller section. One roller of the pull-off roller section is disposed such that the roller conveys a sheet in a direction in which the sheet is to be conveyed by the registration roller, and the other roller of the pull-off roller section is disposed such that the roller conveys a sheet obliquely with respect to the sheet conveying direction of the registration roller.

  • Patent number: 8195469
    Abstract: A speech decoding device of the invention smoothes, in decoding speech signal in a voice-less period, RMS and filter coefficients which is discontinuously transmitted, and provides them to a synthesis filter. Thereby, it is capable of preventing discontinuous changing of the filter coefficient caused by the intermittent transmission of the filter coefficient. As a result, a quality of decoding can be improved. Also, to remove an effect, caused by the smoothing process, from the filter coefficients or the RMS which are transmitted in the past frames, a smoothing factor is adjusted not to perform smoothing while a certain time period (or a certain number of frames) from when a transition is made from a voice period from a voice-less period, or when a decoded feature parameter satisfies a predetermined condition.

  • Patent number: 8111420
    Abstract: A printer control apparatus can be applied to an image forming apparatus in which a plurality of types of readers and a plurality of types of printers can be connected to a single controller, and which enables efficient transfer of image data from the reader to the printer via an image memory of the controller. The controller receives image data from a reader and temporarily stores the same in an image memory, and transmits the stored image data to a printer. The controller acquires a reader processing speed from the reader and a printer processing speed from the printer, and determines, while the image data is being written to the image memory, timing for transmitting the image data written in the memory to the printer according to a difference between the reader processing speed and the printer processing speed and a sub-scan size of the image data.
