## Abstract

A sheet supply device includes a sheet supply tray, a guide fence for restricting sheets along a sheet width direction, a slider block that is slidable along the sheet width direction and supports the guide fence in an upright state, a slide shaft that is inserted into a through hole formed in the slider block and guides sliding of the slider block, and a guide fence lock mechanism including a restriction member on which a hole is formed and that is attached to the slider block swingably (the slide shaft is inserted into the hole). The guide fence lock mechanism restricts sliding of the slider block by holding the restriction member in a lock state where an inner circumferential edge of the hole is pushed onto an outer circumference of the slide shaft, and allows sliding of the slider block when the restriction member is swung to cancel the lock state.

## Claims

### Claim 1

A sheet supply device comprising:
a sheet supply tray on which sheets are stacked;
a guide fence for restricting positions of the sheets along a sheet width direction perpendicular to a sheet supply direction;
a slider block that is slidable along the sheet width direction and supports the guide fence in an upright state;
a slide shaft that is inserted into a through hole formed in the slider block and guides sliding of the slider block along the sheet width direction; and
a guide fence lock mechanism including a restriction member on which a hole is formed and that is attached to the slider block swingably at a position distanced from the guide fence, the slide shaft being inserted into the hole, wherein
the guide fence lock mechanism is configured to restrict sliding of the slider block along the sheet width direction by holding the restriction member in a lock state where an inner circumferential edge of the hole is pushed onto an outer circumference of the slide shaft, and to allow sliding of the slider block along the sheet width direction when the restriction member is swung to cancel the lock state.

### Claim 2 (depends on 1)

The sheet supply device according to claim 1, wherein
the guide fence mechanism further includes
a fulcrum plate that is fixed with a vertical end of the slider block and engaged with a vertical end of the restriction member so as to function as a fulcrum when the restriction member is swung,
an elastic member that is disposed near another vertical end of the slider block and to urge the restriction member toward the guide fence, and
a lever that is fixed with another vertical end of the restriction member and configured to swing the restriction member when manually operated to distance the restriction member away from the guide fence against an urging force of the elastic member.

### Claim 3 (depends on 2)

The sheet supply device according to claim 2, wherein
the guide fence mechanism is provided in a pair, and
one guide fence mechanism of the pair is disposed at one side of the sheet supply tray with respect to the sheet supply direction, and another guide fence mechanism of the pair is disposed at another side of the sheet supply tray with respect to the sheet supply direction.

### Claim 4 (depends on 2)

The sheet supply device according to claim 2, wherein
an engagement hole is formed on the fulcrum plate,
the vertical end of the restriction member is engaged with the fulcrum plate at the engagement hole, and
the engagement hole functions as the fulcrum when the restriction member is swung.

### Claim 5 (depends on 2)

The sheet supply device according to claim 2, further comprising
a pinch plate fixed with the slider block and to be pinched together with the lever when the lever is manually operated.
