According to one embodiment, a magnetic disk device includes a memory and a controller. The memory stores, for a predetermined track on a magnetic disk in the device, a counter, a counter threshold, and weights. The weights are individually set for divided areas of the predetermined track. The weights each have magnitude inversely proportional to a guaranteed number of times of data readout. When writing to an adjacent track of one or more of the divided areas is executed, the controller multiplies a number of times of writing by the weight corresponding to the one or more of the divided areas and adds the number of times of writing to the counter. When a numerical value of the counter reaches the counter threshold, the controller executes refresh to rewrite data in the predetermined track or executes reading for determining whether or not to perform the refresh.

Magnetic disk device and control method

A transport device includes a transport member that transports a recording medium while adjusting a leading end of the recording medium, and a guide member that is disposed upstream from the transport member in a transport direction of the transport member to guide the recording medium to the transport member along a transport path, the guide member being rotatable in a direction to open the transport path while having a downstream portion in the transport direction of the transport member serving as an axis.

Transport device and image forming apparatus

A manual sheet feeding device includes: a sheet feeding rotary body configured to separate and feed recording media placed on a manual sheet feeding unit one by one; a shielding unit configured to cover an outer side surface of the sheet feeding rotary body, the shielding unit having an aperture for exposing at least a part of the sheet feeding rotary body to an outside; and an opening and closing unit configured to open and close the aperture of the shielding unit.

Manual sheet feeding device and image forming apparatus

A medium supply apparatus includes a box member, a bottom plate, and a rotary portion. A medium is stored inside the box member. The box member is inserted into and extracted from a body of an image forming apparatus. The bottom plate is disposed at a bottom portion of the box member. The medium is placed on the bottom plate. The bottom plate is lifted up by an elastic force of an elastic member. The rotary portion is attached to a side wall, among walls of the box member, positioned on a lateral side with respect to a front side toward which the box member is extracted from the image forming apparatus. The rotary portion is rotatable about a location of attachment of the rotary portion. The rotary portion includes a rear portion and a front portion. The rear portion is positioned on a rear side, in contrast to the front side, with respect to the location of attachment. The rear portion is moved upward by a reaction force applied from the body when the box member is extracted. The front portion is positioned on the front side with respect to the location of attachment. The front portion is moved downward by rotation of the rotary portion due to upward movement of the rear portion to lower the bottom plate against the elastic force.

Medium supply apparatus and image forming apparatus

An image forming apparatus includes an opening and closing unit attached to an image forming apparatus body. The opening and closing unit includes: an exterior member pivotably attached to the image forming apparatus body via a first shaft; a base member provided inside the exterior member and pivotably attached to the image forming apparatus body via a second shaft so as to be able to move with the exterior member; and an extension member attached to the base member in a manner capable of being pulled out and retracted.

Image forming apparatus with an extension for a manual feed tray

An image forming apparatus includes a sheet accommodating portion that is attachable to and removable from an apparatus body and that is capable of accommodating a sheet therein; a detecting part that detects the presence/absence of a sheet in the sheet accommodating portion; a fixing part that fixes the status of detection by the detecting part to a sheet absent state when the sheet accommodating portion is not attached to the apparatus body; an informing part that informs a user of the status of the apparatus; and a control part that causes the informing part to inform the user of the possibility of a sheet left in the apparatus when the status of detection by the detecting part changes from a sheet present state to the sheet absent state during standby when printing is not performed.

Image forming apparatus

Provided is an image forming apparatus including a main body that is provided with an insertion hole, and forms an image on a recording medium, and an insertion container in which the recording medium is stored, and that is inserted into the insertion hole, wherein the insertion container includes a first part, a second part that extends rearward in a direction of the insertion from the first part, and that is movable forward and backward in the insertion direction with respect to the first part, a fastening tool that fastens the second part to the first part, a releasing tool that releases the fastening tool when grasped, and that moves forward and backward with the second part, and a protruding tool that protrudes from the second part to the main body when the releasing tool is grasped, and that prevents the second part from being inserted into the insertion hole.

Image forming apparatus, and insertion container

Provided is a transporting device including a transport section that contacts with a material to be transported and that transports the material to be transported, a table on which the material to be transported is placed, a moving member that includes the table provided on an upper surface of the moving member so that an upper surface of the table is higher than the upper surface of the moving member in a vertical direction and moves the material to be transported, which is placed on the table, to a contact position where the material to be transported contacts with the transport section, and a positioning member that contacts with an end portion of the material to be transported in a width direction orthogonal to a transport direction in which the material to be transported is transported by the transport section.
