  • Publication number: 20210286308
    Abstract: When a sheet jam is detected, a processor may perform the following process. In a case where a sheet is spanning a first conveyance path and a drawer unit, the processor maintains a lock unit in a locked state by supplying power to the lock unit via the drawer unit from a power supply without depending on whether a door is in an open state or a closed state. In a case where a sheet is not spanning the first conveyance path and the drawer unit, the processor controls supplying and disconnecting of power to the drawer unit from the power supply in accordance with whether the door is in a closed state or an open state.

  • Publication number: 20210010796
    Abstract: To optimize an imaging range in a depth direction in terms of a relationship with a resolution, an OCT apparatus includes a signal processor that determines a reflected light intensity distribution of an imaging object on the basis of a spectrum of a detected interference light. The signal processor performs spectrum conversion, having a conversion characteristic with which a light source spectrum is converted to a Gaussian distribution curve, on the spectrum of the interference light, and determines the reflected light intensity distribution by Fourier-transforming a spectrum resulting from the spectrum conversion. In the conversion characteristic, the light source spectrum and the Gaussian distribution curve have center wavelengths differing from each other.

  • Publication number: 20200064768
    Abstract: A post-processing apparatus has an input terminal into which a first activation signal output from an image forming apparatus is input. A user switch is operated by a user. A generation circuitry is provided inside the post-processing apparatus. The generation circuitry, by turning on the user switch, generates a second activation signal corresponding to the first activation signal. A power source circuitry is activated in response to the first activation signal input into the input terminal. A post-processing mechanism performs a post-processing process on a sheet using an electric power supplied from the power source circuitry. When the image forming apparatus is in a state of being unable to output the first activation signal, in response to the second activation signal generated by the generation circuitry, the power source circuitry is activated.

  • Patent number: 10459391
    Abstract: An image forming apparatus that is capable of specifying a causal part of an error on the basis of an occurred phenomenon even for a low-skill operator. Causal part candidates are candidates of parts of the apparatus that can cause an error in the apparatus. An associated component is relevant to one of the causal part candidates and a state change thereof is detectable. A detector detects the state change of the associated component. A memory stores the state change of the associated component detected by the detector in association with detected time. A processor executes a function for detecting the error and a function for specifying an error causing part that is the part causing the error from among the causal part candidates based on time at which the error is detected and information stored in the memory.

  • Patent number: 10317188
    Abstract: An imaging apparatus images an imaging object which is stored in a container having an optical transparent wall part tomographically via the wall part. An FD-OCT imaging apparatus sets an optical path length of a reference light in conjunction with a setting of a focal depth such that a position corresponding to the focal depth is between a position conjugate with a first surface and a position conjugate with a second surface in a reflected light intensity distribution representing a relationship between a position in an incident direction of an illumination light and a reflected light intensity. Here, the first surface is a surface on the imaging object side out of surfaces of the wall part. The second surface is another surface on a side opposite to the imaging object out of the surfaces of the wall part.
