A sheet-feeding cassette includes: a first tray having a first wall section and a sheet-urging plate; and a second tray having a second wall section, the second tray being coupled to the first tray in a movable manner whereby an interval between the first wall section and the second wall section is changeable. A wall surface of the second wall section, which comes into contact with the sheet, comes to a position upstream of an upstream end portion of the first tray main body. A downstream end portion of the second tray in the sheet-feeding direction comes to a position downstream of an upstream end portion of the sheet-urging plate in the sheet-feeding direction.

An image-forming device includes a photosensitive drum, a transfer roller, a guide plate for guiding the paper toward the photosensitive drum, and a sponge fixed to the bottom surface of the guide plate. The sponge is softer than the guide plate, so that it can absorb vibrations in the guide plate when the trailing edge of the paper leaves the guide plate.

A shifting mechanism shifts at least one of a sheet accommodating portion and feeding portion, thereby changing a position of the feeding portion relative to sheets. A pressure changing mechanism changes pressure between first and second separating portions. A contact force controlling portion controls the shifting mechanism to provide a first contact force when the feeding portion starts a feeding operation, and controls the shifting mechanism, at a first timing, to reduce the contact force from the first contact force to a second contact force. A pressure controlling portion controls the pressure changing mechanism to provide a first pressure between the first and second separating portions when the feeding portion starts the feeding operation, and controls the pressure changing mechanism, at a second timing, to reduce the pressure from the first pressure to a second pressure while nipping the separated sheet between the first and second separating portions.

A sheet-feeding cassette includes: a stacking member including first engaging sections and second engaging sections provided at intervals which are smaller than those of the first engaging sections; and a regulatory member regulating the position of sheets, the regulatory member including an operation section that is operated at the time of movement of the regulatory member and is capable of being displaced, a first engaged section that is capable of engaging with the first engaging sections and is elastically deformable, and a second engaged section that is capable of engaging with the second engaging sections. The second engaged section is displaced in a direction so as to be disengaged from the second engaging sections in accordance with displacement of the operation section, and the first engaged section is elastically deformed as a result of being interlocked with the second engaged section according to displacement of the operation section.
摘要:
A time required for an output voltage of a source follower to rise from Low to a predetermined voltage depends on a bias voltage. Therefore, by setting a converged voltage of an output voltage to be high by increasing the bias voltage, the time required to rise up to the predetermined voltage can be reduced. Therefore, a first source follower which is biased so that the converged value of the output voltage becomes a predetermined Hi voltage when an input data signal goes from Low to Hi, and a second source follower which is biased so as to become the Hi voltage after a period of one clock when an input data signal goes from Low to Hi, are used. The two source followers are operated with appropriate timing.
