Various embodiments of a printer modification system for modifying a printer to accommodate different sized documents such as elections documents are disclosed herein.

An example paper cassette includes a cassette portion; a sliding portion to slide relative to the cassette portion to adjust a length of the paper cassette, the sliding portion initially being in a shipping position defining a shipping length of the paper cassette and deployable to different deployment positions at which the paper cassette is longer than the shipping length; and a length selection mechanism to: mechanically select one deployment position of the different deployment positions, while the sliding portion is in the shipping position; lock the sliding portion at the one deployment position, relative to the cassette portion when the sliding portion first slides from the shipping position.

According to one embodiment, an image processing device includes a cassette main body, a device main body, a handle, and a pressing member. The cassette main body contains a sheet. The device main body stores the cassette main body retractably in a first direction. The handle is displaceably supported by the cassette main body. The pressing member is supported by the cassette main body. The pressing member presses the device main body in a second direction opposite to the first direction in conjunction with displacement of the handle with respect to the cassette main body.

There is provided a sheet storage device including a regulation unit that includes a first contact portion configured to contact a stacking unit, and a second contact portion configured to contact a facing member. The first contact portion contacts the stacking unit in a state of being urged toward the stacking unit. The second contact portion contacts the facing member in a state of being urged toward the facing member.

A rotary wire-receiving rack includes a winding structure, a shaft, a first handle, a lid, a locking slider, and a second handle. The winding structure includes two bars arranged longitudinally in parallel and two rods arranged horizontally in parallel for winding cables. Both ends of the two rods are linked to the bars respectively. The shaft is arranged parallel to and located between the rods. The shaft is pivoted on the bars. The first handle and the lid are respectively fixed at the two ends of the shaft. The lid has a locking hole, and the locking slider is slidably installed on the shaft near the locking hole. The locking slider is formed with a locking pin that cooperates with the locking hole. The second handle is pivoted at the end of the bar which closing to the locking hole and having a recess for clamping a cable.

In a lock member of a pull-out lock device, while two adjacent sheet containers are both located at an accommodated position in an image-forming apparatus main body, a contact member is in contact with one of the sheet containers and thus the lock member rotates around a rotation axis, and a lock moves to an unlock position to allow the other sheet container to move in a pull-out direction, and while the other sheet container is located at the accommodated position and the one of the sheet containers is pulled out from the accommodated position in the pull-out direction and thus the contact between the one of the sheet containers and the contact member is removed, the lock member rotates around the rotation axis and the lock moves to a lock position to prohibit the other sheet container from moving in the pull-out direction.

A sheet supporting apparatus includes a body, a supporting portion configured to be held in an elevating manner by the body and to support a sheet, a sheet regulation portion regulating a position of the sheet supported on the supporting portion, a movement portion capable of moving between a first position where the sheet regulation portion regulates the position of the sheet supported on the supporting portion, and a second position where the supporting portion is regulated from elevating with respect to the body, and a movement regulation unit regulating the movement portion from moving to the second position.

A sheet processing apparatus has a main body with an insertion slot for a sheet cassette. The sheet cassette has a moveable pin member. A housing in the main body includes a lever partially rotatable about a first axis. The lever has a pin engagement portion at an end of the lever that rotates about a second axis and has an engagement groove into which the pin member can be inserted from a first pin engagement position and a second pin engagement position when the lever has rotated about the first axis. An elastic member applies a force to the lever to rotate the lever toward the insertion direction of the cassette. The housing includes a chassis having a guide groove extending along the insertion direction. The guide groove includes an inclining portion that is inclined with respect to the insertion direction.

To enable placement of a regulating member which regulates a position of an end of a paper sheet at a desired position, and stable sheet feeding. A fixing member for standard size (33) is guided to engage with a fixing hole for standard size (42) and, in a state where the fixing member for standard size (33) positions a trailing end regulator (24), a fixing member for non-standard size (34) does not engage with a rack aear (43).
