摘要： Motor-control device for an image forming apparatus includes a motor, an encoder, a microcomputer, and a driving circuit. The encoder generates a pulse signal in response to rotation of the motor. The microcomputer includes a CPU, a RAM and a ROM. The CPU detects actual rotational speed of the motor based upon the pulse signal generated by the encoder. The CPU cyclically provides a driving signal by comparing the actual rotational speed with a predetermined target rotational speed of the motor. An operating cycle is proportional to a cycle of the pulse signal generated by the encoder. The driving circuit drives the motor based upon the driving signal provided by the CPU. The CPU determines the operating cycle based upon the predetermined target rotational speed. The CPU also determines whether the motor condition is normal or abnormal by comparing the driving signal with a predetermined reference driving signal.

摘要： An image recording apparatus for recording an image of an original on a developer sheet with the use of a microcapsule, in which the developer sheet and the microcapsule sheet having a surface coated with immense number of photosensitive and pressure-rupturable microcapsules are subjected to pressure development by a pair of pressurizing rollers. To ensure that the pressure development is performed under the condition where the developer sheet and the microcapsule sheet are superposed one on the other, the nip and retract timings of the pressurizing rollers are determined properly according to the present invention. For example, the developer sheet is conveyed at a speed asynchronous with the microcapsule conveying speed and the conveyance of the developer sheet is stopped after its leading edge is introduced between the rollers held in spaced apart condition. The rollers are brought to the nip position to thereby start the pressure development when the exposure start line on the microcapsule sheet is in alignment with the leading end of the developer sheet. The retract timing is determined, for example, depending upon the size of the developer sheet.

摘要： An image forming apparatus has a thermal fixing unit which includes a heater to thermally fix an image on a recording medium. The temperature in the apparatus goes down when a replaceable unit is exchanged. A temperature sensor detects the reduction in temperature. A status sensor detects an exchanging state in which the replaceable unit is exchanged and outputs a detection signal indicating the exchanging state. A CPU judges that the heater is properly operating even if the temperature signal indicates the reduction in temperature when the detection signal is outputted.

摘要： Sheet loading in an image recording apparatus is automatically performed by drawing the leading edge of an elongated, web-like image photosensitive recording medium out of a sheet cartridge, passing it through a predetermined sheet feed path provided between the sheet cartridge and a take-up shaft, and attaching the leader portion of the recording medium to the take-up shaft. A plurality of sensors are disposed alongside the sheet feed path for sensing that the sheet loading is being appropriately performed. The recording medium is successively moved to each of the sensors, and if the recording medium is not sensed thereby, it is rewound around the cartridge shaft.

The single specific process unit is controlled by the general-purpose process unit. The specific process unit implements only two tasks, one task being compression of the image data in the compression format for each of the plurality of functions, the other task being expansion of the image data which has been compressed for each of the plurality of functions. The output unit outputs the image data. The general-purpose process unit determines which the general-purpose process unit or the specific processing unit should implement the compression/expansion.
