A magazine for packs of blanks includes a vertical channel configured for inserting and extracting packs of blanks, a succession of groups of supporting parts movable between a retracted position to allow the packs of blanks to move along the channel towards a portion under the supporting part, and an at least partly extracted position, in which the supporting part intercepts a pack of blanks moving down the channel and provides a steady support for the pack of blanks, and transmission means configured to automatically move each supporting part from the retracted position to the at least partly extracted position when the supporting part immediately below it intercepts a respective pack of blanks, thereby defining the steady support.

A sheet storage device includes a sheet storage unit to store sheets, a regulating unit in the sheet storage unit, and a lifting unit. The regulating unit regulates a position of a rear edge portion of the sheets in a sheet conveyance direction and includes a supporting portion, an urging member, and a pressing portion having a pressing surface in which a position to be in contact with lower sheets is a pressing surface lower portion, and a position to be in contact with upper sheets located higher than the lower sheets is a pressing surface upper portion. The pressing surface can be in a first state, where the pressing surface upper portion is located downstream from the pressing surface lower portion in a pressing direction, or in a second state, where the pressing surface lower portion is located downstream from the pressing surface upper portion in the pressing direction.

A paper feed device having regulation plates that are movable on a paper feed tray for loading paper and regulate edges of the paper, includes: a driver that moves the regulation plates; and a hardware processor that acquires paper information corresponding to a characteristic of the loaded paper, and causes the driver to move the regulation plates according to the acquired paper information.

A controller drives a floating unit and a conveyor to perform a sheet feed operation, during the sheet feed operation, acquires an amount of received light at a detector during floating of sheets floated by the floating unit each time each sheet is conveyed by the conveyor, and perform a following control of lifting a stacking tray upon the acquired amount of received light being less than a threshold value. The controller, after start of the sheet feed operation, samples amounts of received light at the detector during floating of the sheets floated by the floating unit, performs a threshold value determination process of determining the threshold value by using the sampled amounts of received light, and starts the following control upon determining the threshold value.

A timing specifying device includes count processing circuitry to count an input reference clock; and timing control circuitry configured to set a parameter having an integer part and a fractional part in the count processing circuitry. The count processing circuitry counts the reference clock, outputs a timing signal indicating that a time corresponding to an integer value has passed, and counts a value corresponding to the fractional part at a timing at which the timing signal is output. The integer value is a value indicated by the integer part. The count processing circuitry stops counting of the reference clock when a value obtained by counting the value corresponding to the fractional part carries over from a fraction.

A feeding device includes an accommodation unit that accommodates paper, a feeding tray on which the paper is placed in the accommodation unit and that is controlled so as to be lifted and lowered in a case of being replenished with the paper, and a processor configured to determine a lifting and lowering speed of the feeding tray according to an operation by a user, and perform control such that a lifting and lowering speed of the feeding tray becomes slower than the determined lifting and lowering speed in a case of a state where the determined lifting and lowering speed of the feeding tray is unable to be realized.

According to aspects of the present disclosures, when a cancel command is input during a document conveying process, drive of a conveying motor is stopped. Then, a movable plate of a feed tray is moved down from a supplying position to a lowermost position being a non-supplying position, and the drive of the conveying motor is restarted. The conveying motor is driven at least until a document sheet is discharged from a conveying path.

Various embodiments of a paper feed and tray extension system for adapting printer components to accommodate election document dimensions are disclosed herein. To accomplish this, a printer feed adapter system includes a paper tray extension for implementation within an existing printer that extends a paper tray to enable the paper tray to receive sheets of paper that have required dimensions for election documents. Further, paper catch extender extends a paper catch to enable the paper catch to catch election document sheets following processing by the printer.

In a scanner, a medium transport apparatus includes an apparatus main body including a medium transport path from a supply unit, which supplies a medium, to a discharge unit, which discharges the medium, a switcher that switches an attitude of the apparatus main body with respect to a mounting surface on which the apparatus main body is mounted, and a controller that, when the attitude of the apparatus main body with respect to the mounting surface is switched, performs control in accordance with the attitude after the switching.
