Abstract

PURPOSE:To supply toner smoothly to a device by one touch without causing toner staining by providing a toner cartridge case with a stopper mechanism and a rotary lid mechanism. CONSTITUTION:A rotary lid 4 which rotates as shown by an arrow and has an aperture at the bottom part is provided to the bottom part of a main case body 1 and a lever 5 is fitted to the shaft of the rotary lid 4; and the lever 5 is energized with a spring 6 in the closing direction of the rotary lid and a stopper pin 7 for rotation control in a specific direction is inserted into the lever 5. When the rotary lid 4 is rotated through the rotation of the lever 5 by up to 90 deg., the lid becomes vertical and the bottom part of the main case body 1 is fully open, thereby supplying toner to a printer.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a toner cartridge for an electrophotographic printer.

[Conventional technology]

A conventional toner cartridge for replenishing toner in an electrophotographic printer has a structure in which the bottom of the case body 1 is sealed with a slide t2, as shown in FIG. Toner was supplied to the printer by removing the stopper pin 3, sliding the slide lid 2 in the direction of the arrow, and opening the bottom.

[Problem that the invention seeks to solve]

In the conventional toner cartridge described above, toner often adheres to the slide lid 2, and when the slide lid 2 is removed, toner adheres to the exterior of the device, making the device easily dirty and difficult to handle. Furthermore, after the cartridge is attached to and removed from the apparatus, two operations are required: pulling out the stopper pin and pulling out the slide cover, which has the disadvantage of being difficult to handle.

An object of the present invention is to provide a toner cartridge that simplifies toner replenishment work and prevents toner staining.

[Means to solve the problem]

The present invention provides a toner cartridge for supplying toner to the printer by unsealing the bottom of the case body that is attached to the cradle of an electrophotographic printer. A rotary lid is provided which opens the bottom part by a lever, and the rotary lid is always biased in the closing direction.Furthermore, a stopper pin for regulating rotation in a specific direction is inserted into the lever of the rotary lid, and the This toner cartridge is characterized in that a release pin for removing the stopper pin is embedded.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings.

In FIG. 1, the toner cartridge according to the present invention is
At the bottom of the case body 1 that is attached to an electrophotographic printer,
A rotary lid 4 that opens the bottom by rotating in a specific direction (direction of the arrow) is provided, a lever 5 is attached to the shaft of the rotation 114, and the lever 5 is attached by a spring 6 in the direction in which the rotary lid closes (in the direction opposite to the arrow). In addition, a stopper pin 7 for regulating rotation in a specific direction is inserted into the lever 5. On the other hand, the cradle 8 of the printer is provided with a release pin 9 for removing the stopper pin 7.

The lever 5 is always pulled back toward the case body 1 in the opposite direction of the arrow by a spring 6, and the stopper pin 7 of the case body 1 prevents the toner cartridge alone from falling in the direction of the arrow.

In the embodiment, when the toner cartridge case is mounted on the cradle 8 of the printer, the stopper pin 7 of the case body 1 is pulled out from the lever 5 by the release pin 9 of the cradle 8, and the lever 5 can be tilted in the direction of the arrow. can. When the rotary lid 4 is rotated to the maximum of 90 degrees by operating the lever 5, it becomes vertical and the bottom of the case body 1 is fully opened, allowing toner to be supplied to the printer.

〔Effect of the invention〕

As described above, the present invention has the effect that toner can be smoothly supplied to the device with a single touch without causing toner contamination by providing the toner cartridge case with a stopper mechanism and a rotating lid mechanism.
