Description

  The present invention relates to a photosensitive drum storage container that stores a plurality of photosensitive drums.

  Conventionally, a photosensitive drum is used in an image forming apparatus such as an electrostatic copying machine or an electrostatic printing machine. The photosensitive drum includes a cylindrical portion that is configured in a cylindrical shape and has a photosensitive layer formed on the surface thereof, and a flange portion that is disposed at one end and the other end in the longitudinal direction of the cylindrical portion. Here, the photosensitive layer is formed of a material that is easily damaged. Therefore, when the photosensitive drum is transported, a plurality of photosensitive drums are accommodated in the housing case in a state where the buffer sheet is wound around the photosensitive layer, and the photosensitive layer is prevented from being damaged during the transportation.

  Further, as a technique for storing a plurality of photosensitive drums without winding a buffer sheet, a photosensitive drum storage container configured by a pair of upper and lower trays and holding a plurality of photosensitive drums sandwiched between the pair of trays is provided. It has been proposed (see, for example, Patent Documents 1 and 2).

  Further, it is configured by a single member including a sheet-like main body portion and a pair of support portions that are foldably connected to the main body portion, and the pair of support portions are bent substantially perpendicular to the main body portion. Thus, there has also been proposed a photosensitive drum storage container in which both ends of a plurality of photosensitive drums are held by a pair of support portions and a plurality of photosensitive drums can be suspended in a suspended state (see, for example, Patent Document 3). ).

  (3) The storage tray 10 is configured to include a first pressing portion 19 that presses one end of the photosensitive drum 50 and a second pressing portion 20 that presses the other end of the photosensitive drum 50. Accordingly, the photosensitive drum 50 accommodated in the accommodating recess 11 of the lower accommodating tray 10 can be pressed and supported by the first pressing portion 19 and the second pressing portion 20 of the upper accommodating tray 10, and therefore the photosensitive drum 50. Can be held more stably.

  (4) In the first embodiment, the width of the gear 52 of the photosensitive drum 50 is configured to be larger than the width of the second flange portion 53. Therefore, the area of the pressing surface of the first pressing part 19 is configured to be larger than the area of the pressing surface of the second pressing part 20. Thereby, the gear 52 is pressed by the first pressing portion 19 and the second flange portion 32 is pressed by the second pressing portion 20, thereby pressing the photosensitive drum 50 in a wider area without damaging the photosensitive layer. it can.

  (5) The photosensitive drum storage container 1 includes the lid member 40. As a result, the photosensitive drum 50 accommodated in the uppermost accommodation tray 10 can be protected by the thin cover member 40 without further stacking the accommodation tray 10 on the uppermost accommodation tray 10. Therefore, the photosensitive drum storage container 1 can be made compact.

(6) The storage tray 10 includes the first tray 10A and the second tray 10B. Further, the first tray support portion 15 and the second tray support portion 16 in the first tray 10A and the second tray 10B are connected to the first tray 10A and the second tray so that the first drum support portions 12 overlap each other in the thickness direction Z. When the tray 10B is stacked, the storage space 30 is disposed at a position where the storage space 30 is formed. Accordingly, when the storage trays 10 are stacked in a plurality of stages, the directions of the photosensitive drums 50 stored in the storage trays 10 can be matched. Therefore, the workability in taking out the photosensitive drum 50 accommodated in the photosensitive drum accommodating container 1 can be further improved.
Further, when the first trays 10A are stacked and when the second trays 10B are stacked, the first tray support portion 15, the second tray support portion 16, the first tray contact portion 17, and the second tray holder are stacked. Since the contact portion 18 is disposed at a position overlapping the thickness direction, the storage space 30 is not formed. Thereby, by stacking the first trays 10A or the second trays 10B, the plurality of first trays 10A and the second trays 10B can be stacked in a state where the thickness does not increase, thereby reducing transportation costs and storage costs. Reductions are made.
