An electronic device support stand is a support stand for electronic devices that enables rotating the supported electronic device in a confined space with substantially no force while holding the electronic device securely. The electronic device support stand has a holding unit configured to hold an electronic device; and a base unit that supports the holding unit. The holding unit includes a pivot mechanism enabling rotating the supported electronic device with substantially no load around an axis parallel to the surface on which the base unit is placed.

The temperature of heat elements of a thermal head can be controlled with high precision by a process with a low processor load. A printerthat prints on thermal roll paperbased on print data has a thermal headwith multiple heat elementsarrayed in a sub-scanning direction CR perpendicular to the conveyance direction F of the thermal roll paper. The printerhas a current control unitthat segments the heat elements of the thermal headinto plural blocks, and controls the energize timing of the heat elements in each block based on the number of heat elementsthat are energized in the thermal head

Printing device, control method of a printing device, and a storage medium

Swinging open the upstream-side cover part () and downstream-side cover part () of the check scanning apparatus () on a common support pivot () opens a U-shaped check transportation path (). The check transportation path () can be opened with a simple single-action operation to remove checks () jammed in the check transportation path () and for maintenance of the magnetic head () and contact image sensors (and). When the task is completed, the open check transportation path () can also be returned to the original closed position by a simple single-action operation. If only those parts that require maintenance are exposed when the check transportation path is open, tasks that require opening the transportation path can be done without damaging other parts and without soiling the operator's fingers.

Check processing device

A head performs recording or reading information with respect to a sheet-shaped recording medium. A pair of rollers sandwich therebetween and transport the recording medium in a transport path of the recording medium passing through the head. A cantilevered frame extends while being cantilevered in a direction traversing the transport path. One end of an opening and closing unit is rotatably supported by the cantilevered frame. The opening and closing unit is revolvable around the one end to move between a closed position where the opening and closing unit covers at least a transport portion by the pair of rollers in the transport path and an open position where the transport position is exposed to the outside.

Recording medium processing apparatus

A media processing device enables opening an openable unit so that the media transportation path is open with a minimal operation and little operating force. The media processing device has an openable unit that can rotate on a first pivot axis CLfrom a closed position to an open position; a lock member that can move to a locked position where it locks the openable unit in the closed position and an unlocked position where the lock is released; and an operating lever that can rotate on a second pivot axis CLthrough a range from a first pivot position passed a second pivot position to a third pivot position. A first cam mechanism converts rotation of the operating lever from the second pivot position to the third pivot position to rotation of the openable unit from the closed position to the open position.

Media processing device

A scanner unit includes a scanner for imaging a print medium, a base unit that supports the scanner, a pressure feed roller disposed opposite the scanning surface of the scanner, a guide member for guiding the print medium to the scanner, a frame member that supports the pressure feed roller and the guide member, and a motor that drives the pressure feed roller. The frame member is supported pivotably to the base. In other embodiments the scanner unit can include a roller shaft such that the pressure feed roller is coaxially affixed to the roller shaft and the frame member supports the roller shaft, a first gear on the roller shaft, and a second gear that transfers drive power from the motor to the second gear.

Media processing apparatus and scanner unit

The medium conveying mechanism includes a motor, a driving pulley adapted to be rotated by the motor, an endless belt wound around the driving pulley and adapted to be moved by the driving pulley in a belt moving direction, a first driven pulley around which the endless belt is wound and adapted to be rotated by the endless belt, a first conveying roller disposed on the medium conveying path and adapted to be rotated by the first driven pulley to convey the medium, and a first pressure roller disposed to correspond to the first conveying roller so as to press the medium against the first conveying roller. A distance in the medium conveying path between the information reading position and a nip portion between the first conveying roller and the first pressure roller is shorter than a distance between a leading end of the conveyed medium and back end of the recording area. The first driven pulley is disposed upstream from the driving pulley in the belt moving direction.

Medium processing apparatus

A media processing device can convey checks at a constant speed passed an information reading position without slipping and without increasing the relay capacity of the transportation roller. The check processing devicehas two transportation rollersandbetween the scanning positionA of the contact image scannerand the separation rollerand retard rollerthat produce a transportation load or transportation load variation. The upstream-side transportation rollerturns faster than the downstream transportation rollerso that the checksare fed with slack between these transportation rollersand. Because of this slack in the partof the checkbetween the transportation rollersand, the transportation load from the separation mechanism does not act on the downstream transportation roller. The transportation load acting on the transportation rollerthat feeds the checksto the scanning positionA can thus be reduced, variation in the transportation load can be suppressed, checks can be conveyed at a constant speed to the scanning positionA, and a drop in the reading accuracy of the contact image scannercan be prevented.

A scanner unit that includes a scanner for imaging a print medium, a base that supports the scanner, a pressure feed roller disposed opposite the scanning surface of the scanner, a guide member for guiding the print medium to the scanner, a frame member that is supported pivotably to the base, and a motor that is supported on the base. The frame member supports the pressure feed roller and guide member and the motor drives the pressure feed roller.

A media transportation mechanism comprising a first transportation roller pair and second transportation roller pair disposed in the transportation path on the upstream and downstream sides, respectively, of image scanners convey a slip over a sliding guide surface. The first transportation roller pair produces a feed force towards the sliding guide surface so as to push the leading end edge of the slip to the sliding guide surface. The second transportation roller pair produces a feed force in the direction away from the sliding guide surface so as to push the trailing end edge of the slip to the sliding guide surface.

A stepped support parthaving support surfacestopositioned to the scanner feed rollerside of the scanning surfaceis disposed to the edge of the scanning surface

Scanner unit and a hybrid apparatus using it

A platen gap adjustment assembly for a printing apparatus including a printer using the platen gap adjustment assembly to adjust the platen gap between a platen and a print head when printing on a print medium transported between the platen and the print head. The platen gap adjustment assembly includes a guide shaft, which slidably supports a carriage carrying the print head and a pair of mounting members each supporting the guide shaft. The mounting members have positioning engagement parts for holding or maintaining the position of an eccentric shaft in a given position which controls the position of the positioning engagement parts relative to the mounting members. An urging member urges one of the mounting members with the guide shaft fit therein in the direction for causing the positioning engagement parts into one of a given set of positions.
