  • Publication number: 20210155019
    Abstract: A medium transport apparatus includes a body portion, an inversion unit, and an extension unit. The body portion has a second manual feed path for a sheet material. The inversion unit is configured to be mounted on and separated from the body portion, covers the second manual feed path when the attachment/detachment portion is mounted the body portion, and exposes a portion of the second manual feed path when the attachment/detachment portion is separated from the body portion. The extension unit is configured to be attached to and detached from the attachment/detachment portion. The extension unit extends, in a state in which the inversion unit is separated, the second manual feed path in a transport direction of the sheet material by being detached from the inversion unit and attached to the body portion.

  • Patent number: 10876483
    Abstract: A control device for an internal combustion engine is configured, where a designated cam switching condition is met, to execute a boost pressure control processing and an air amount control processing. In the boost pressure control processing, the control device controls a boost pressure control device such that a boost pressure control parameter does not increase in synchronization with execution of a cam switching operation and decreases in accordance with an increase of a required engine torque after the execution of the cam switching operation. In the air amount control processing, the control device controls the opening degree of a throttle valve to its closed side in synchronization with the cam switching operation such that a difference of an in-cylinder charge air amount is not produced before and after the execution of the cam switching operation.
