    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 imaging device employing a continuous recording sheet which carries thereon a plurality of photo and pressure sensitive microcapsules. Each microcapsule contains therein a dye precursor and a photo-curable resin. By exposing the recording sheet to an optical image, a corresponding latent image is formed thereon with hardened and unhardened microcapsules. The unhardened microcapsules are ruptured by a pressure-developing means and dye precursors streamed out of the ruptured microcapsules react to developer coated on a separate cut-sheet type developer sheet. In order to prevent the pressure-developing means from being polluted by components of microcapsules of the recording sheet, all over the portion of the recording sheet, on which an optical image is not exposed, is fully exposed to a light to harden substantially whole microcapsules carried thereon.

    摘要: An image recording apparatus for recording an image of an original on a photosensitive recording medium. Light emitted from a light source is irradiated onto the original to optically scan the original, and light reflected from or transmitted through the original is applied to the recording medium to thereby record the image on the recording medium. The density of an image to be recorded on the photosensitive recording medium is adjusted by changing the scanning speed while maintaining an amount of light emitted from a light source at constant, whereby a load imposed to the light source is reduced which may otherwise be increased if an amount of light emitted therefrom is changed to adjust the image density.

    摘要: In an image recording apparatus utilizing a photo and pressure sensitive recording medium, an exposure unit emits a light to shine upon an original, and directs the light reflected from the original, toward the recording medium to expose the same thereby forming a latent image. A pressure developing unit is provided for pressurizing the exposed recording medium to develop the latent image thereon. A transport arrangement transports the recording medium from the exposure unit to the pressure developing unit. A regular reflection unit is provided for regular-reflecting the light from the exposure unit to expose the recording medium to the regular reflection light, thereby curing the recording medium.
