A paper-sheet counting machine (10) includes: a recognition and counting unit (24) configured to count paper sheets; a stacking unit (26) configured to stack therein the paper sheets that have been counted by the recognition and counting unit (24), an opening being provided in a front face of the stacking unit (26); a rotary guide unit (28) provided to the stacking unit (26) and configured to allow the paper sheets that have been counted by the recognition and counting unit (24) to be stacked in the stacking unit (26); a shutter (40) configured to close the opening provided in the front face of the stacking unit (26); a shutter drive unit (50) configured to drive the shutter (40) to open and close the opening provided in the front face of the stacking unit (26); and a control unit (70) configured to control the shutter drive unit (50).

The pinch roller mechanism comprises: a slider which is supported by a rail movably in a left-right direction; a roller support member which moves in an up-down direction while being supported by the slider, and a pinch roller which is rotatably supported by the roller support member. The slider includes a window that exposes the pinch roller diagonally upward on the upstream side in the conveyance direction.

There is provided a feed apparatus including: a support unit supporting a sheet; a feed roller; a first arm; a recess portion; a second arm; a biasing member; an operation lever; and an engagement portion. The engagement portion is configured to be separated from the second arm at the first position in a case that the feed roller abuts against the support surface. The engagement portion is configured to be engaged with the second arm in a case that the first arm swings in a direction in which the feed roller is separated from the support surface. The second arm is configured to swing from the first position to the second position in conjunction with swing of the first arm in a direction in which the feed roller is further away from the support surface.

An operation knob that turns a drum is exposed at the outer side of a left side face of a temporary holding section, and a knob cover is disposed at the outer side of the operation knob. When an opening guide of the temporary holding section is in a closed state and is closed onto the upper side of the drum, the knob cover is put into a covering state, via a stud, preventing operation of the operation knob. When the opening guide of the temporary holding section is turned in an opening direction from the closed state and opens apart from the upper side of the drum, the knob cover is turned in an exposing direction by the action of a spring and put into an exposing state.

A feeding unit to feed blanks in a packer machine having: a frame; a hopper for holding a stack of blanks, supported by the frame, and having a pick-up opening, through which one blank at a time can be retrieved from the stack; and a conveyor, supported by the frame, which moves the blanks along a moving path ending in the hopper. The feeding unit can be adjusted by a format change operation to accommodate blacks of different formats by changing the feeding unit from a first configuration for containing a first format of blanks, to a second configuration for containing a second format of blanks, different from the first format. The hopper has a reference element, which, in use, is placed in contact with the stack of blanks to establish reference positions for the blanks relative to the frame that do not move due to a format change operation.

This disclosure relates generally to medical devices, particularly to drawer-type paper tray structures for loading paper into electrocardiograph machines. A paper tray structure provided comprises a paper tray and a door component. The door component comprises a door located in front of the paper tray. The door component is connected to the paper tray movably and is configured to move repeatedly between a first position and a second position relative to the paper tray; the paper tray comprises a first restriction surface and a second restriction surface corresponding to the first and second positions respectively.

A sheet feeding device includes: a main assembly; a holding unit detachably mountable to the main assembly; a portion-to-be-engaged provided on the main assembly; a rotatable member, provided in the holding unit, for feeding a sheet; and a guiding member for guiding feeding of the sheet. The guiding member is provided in the holding unit and includes an engaging portion engageable with the portion-to-be-engaged. The guiding member is movable between an engaging position where the portion-to-be-engaged and the engaging portion are engaged with each other to guide the sheet and a guiding position where the portion-to-be-engaged and the engaging portion are disengaged from each other to guide demounting and mounting of the holding unit.

An image forming apparatus includes a first sheet-transport-path portion that allows a sheet to be transported toward an image forming unit included in an image forming apparatus body; a second sheet-transport-path portion that allows a sheet fed from sheet trays, holding sheets and vertically stacked in multiple rows one above another, to be transported toward the image forming apparatus body; and an opening-closing member supported so as to be movable around a rotation axis between an open position, in which the opening-closing member collectively opens the first sheet-transport-path portion and the second sheet-transport-path portion to an outside, and a closed position, in which the opening-closing member collectively closes the first sheet-transport-path portion and the second sheet-transport-path portion.

An image recording apparatus includes: a housing including a frame and a conveyance path; a recording device which records an image on a sheet conveyed along the conveyance path; a first roller located upstream of the recording device; a second roller opposed to the first roller; a guide member pivotable between a first position for partly defining the conveyance path and a second position where the conveyance path is open; a roller holder coupled to the guide member and supporting the second roller; an urging portion which urges the second roller toward the first roller; and an engaging portion supported by the roller holder and configured to, when the guide member is located at the first position, be engaged with the frame to position the roller holder to a third position where the second roller contacts the first roller by an urging force of the urging portion.

A recording device includes an edge detection unit configured to detect an edge of a medium on a conveyance path, and a control unit configured to receive detection information from the edge detection unit, wherein the control unit acquires, based on the detection information from the edge detection unit, a direction of skewing of the medium and/or an amount of the skewing on the conveyance path and outputs skewing information including the direction of the skewing and the amount of the skewing.
