  • Publication number: 20240149642
    Abstract: A vehicle air conditioner for minimizing the leakage of air through a dual blocking structure between upper and lower flow paths, and having a dual blocking structure. An air-conditioning case having an inner air flow path is divided into an upper flow path and a lower flow path. A heat exchanger for cooling and a heat exchanger for heating are provided in the air flow path of the air-conditioning case. A member having through-holes is disposed downstream of the heat exchanger for heating in the flow direction of air and allows the air that has passed through the heat exchanger for heating to pass therethrough. The member having through-holes has a horizontal member dividing the upper flow path from the lower flow path. A leakage-preventing means is overlapped with the horizontal member so as to prevent the air in the upper flow path and the lower flow path from mixing.

  • Publication number: 20230129634
    Abstract: According to examples, an apparatus may include an input tray coupled to a media path and an output tray to receive media from the media path. The output tray may be automatically positioned to an open position based on the media being inputted into the input tray. A movable section may be movably coupled to the output tray. In some examples, the movable section may automatically move relative to the output tray based on the output tray being automatically positioned to the open position.

  • Patent number: 11383524
    Abstract: In some examples, an apparatus can include a supply reservoir including print substance, and a rotary valve having a central rotary axis, where the central rotary axis is perpendicular to a height of the supply reservoir, where the rotary valve is in a closed position such that the print substance is unable to be supplied from the supply reservoir.

  • Patent number: 10730709
    Abstract: In an example implementation, an example printer system includes a lift, an indicator, a trigger, and a reset mechanism. In an example implementation, a lift is orientable by an amount of media when adjacent to the lift and a trigger has a first portion engageable with the lift at a first orientation of the lift. In an example implementation, the trigger causes the indicator to move towards a first location relative to an aperture defined by an exterior surface in response to engagement with the lift. In an example, the reset mechanism has a first portion engageable with the lift at a second orientation of the lift and the reset mechanism causes movement of the indicator away from the first location in response to engagement with the lift.

  • Patent number: 10435265
    Abstract: A system for presenting media sheets includes a finisher output bin assembly. The finisher output bin assembly includes a translatable output floor, and a guide substrate coupled to the translatable output floor to guide the translatable output floor relative to the guide substrate in at least one coordinate direction. The finisher output bin assembly includes an output structure mechanically coupled to the translatable output floor to drive the translatable output floor relative to the guide substrate.

  • Publication number: 20190208069
    Abstract: According to an example, a printing apparatus may include a first output bin, a second output bin, a first light source positioned to illuminate a portion of the first output bin, a second light source positioned to illuminate a portion of the second output bin, and a controller. The controller may activate the first light source in response to a media being outputted to the first output bin and may activate the second light source in response to a media being outputted to the second output bin to direct a user to the first output bin and/or the second output bin containing a most recently printed media.
