Abstract
A detector detects a size of a recording medium stored in a tray of a device. The tray includes a first regulating member that can slide in a width direction of the recording medium, and a second regulating member that can slide in a feed direction of the recording medium. A first movable member engages with the first regulating member, and a second movable member, overlapped by the first movable member, engages with the second regulating member. Both the first and second movable members rotate around a common pivot and include convex members on peripheral edges thereof. Switches are selectively pressed by the convex members when the tray is attached to the device.
Claims5
A detector for detecting a size of a recording medium in a device, comprising:
- a tray that stores the recording medium to be fed to the device, the tray being detachably attached to the device, including
- a first regulating member capable of sliding in a width direction of the recording medium according to the size of the recording medium, and
- a second regulating member capable of sliding in a feed direction of the recording medium according to the size of the recording medium;
- a first movable member that engages with the first regulating member, rotates around a pivot in conjunction with the first regulating member, and includes a plurality of first convex members on a peripheral edge thereof;
- a second movable member, overlapped by the first movable member, that engages with the second regulating member, rotates around the pivot in conjunction with the second regulating member, and includes a plurality of second convex members on a peripheral edge thereof, the first and second convex members are formed equidistant from the pivot, wherein the first convex members and the second convex members form a plurality of combined convex members;
- and
- a plurality of switches that are selectively pressed by the plurality of combined convex members when the tray is attached to the device.
An image forming apparatus comprising:
- a detector for detecting a size of a recording medium in a device, including
- a tray that stores the recording medium to be fed to the device, the tray being detachably attached to the device, including
- a first regulating member capable of sliding in a width direction of the recording medium according to the size of the recording medium, and
- a second regulating member capable of sliding in a feed direction of the recording medium according to the size of the recording medium,
- a first movable member that engages with the first regulating member, rotates around a pivot in conjunction with the first regulating member, and includes a plurality of first convex members on a peripheral edge thereof,
- a second movable member, overlapped by the first movable member, that engages with the second regulating member, rotates around the pivot in conjunction with the second regulating member, and includes a plurality of second convex members on a peripheral edge thereof equidistant from the pivot with the first convex members, wherein the first convex members and the second convex members form a plurality of combined convex members, and
- a plurality of switches that are selectively pressed by the plurality of combined convex members when the tray is attached to the device.
