Description

  The present invention relates to a small tool storage structure and a tool storage / removal method in an optical electronic apparatus, and more particularly to a driver storage structure provided in a lens cap and a driver storage / removal method.

  As accessories attached to products such as electronic devices, a remote controller, a handle, a power cable, a small driver for maintenance, etc. are generally prepared. Of these, drivers that are small and highly likely to be lost are conventionally stored in product packaging boxes in sachets, and the user needs a driver for work such as lamp replacement on the product. In some cases, the driver was taken out of the packaging box.

However, in such a situation, there is a problem that the driver is lost or not in time when necessary. The reason is that the storage location of the driver is not clear, and the product main body and the driver storage portion are not always in the same location. A similar problem has occurred in projectors, which are optical electronic devices that have been rapidly increasing in demand recently. Various countermeasures have been proposed as a method for storing tools. For example, patent literature describes a general method for storing tools. 1 discloses a fixing method by hanging a hook. Japanese Patent Application Laid-Open No. 2004-26883 discloses a tool mounting portion provided on an inner surface of an opening / closing door with a dedicated tool for removing a lid member for closing an opening for attaching an optional device provided on a side surface of the image forming apparatus. An image forming apparatus provided with a tool mounting unit attached to the tool mounting unit and having a function such as detection of opening / closing of an open / close door is disclosed. Further, in Patent Document 3, as a storage structure for mounting a dedicated tool on a housing, a base embedded with a magnet that is in surface contact with substantially half of one side of the dedicated tool, and a substantially half of the other side that is not in surface contact. A housing having a storage structure including a recess provided corresponding to a position is disclosed.

  In the fixing method by hanging the hook described in Patent Document 1, the tool is only fixed in the vertical direction with respect to the surface to which the hook is fixed, and is not fixed in the horizontal direction with respect to the surface. It cannot be applied to storage of tools for electronic devices such as projectors. Moreover, in the storage structure of the exclusive tool described in Patent Document 2, since it is attached to the tool mounting portion provided on the inner surface of the wide open / close door, it can be easily attached and detached. Is difficult. The storage structure described in Patent Document 3 can be stored in a narrow space, but there is a problem that it is necessary to provide a magnet and there is a concern about the influence on the surroundings.

  For example, a small driver provided in a projector or the like is used when a handle is attached or a lamp is replaced. Since this small driver is small, it is easy to lose it, and it is not always necessary when using the product, so it is easy to get out of hand when necessary. It is conceivable to store a small driver in the product body, but there are several problems. The projector is provided with an opening for lamp replacement and a lamp cover for closing the opening. When an opening / closing structure is provided in the housing of the product main body so that the small driver is stored inside the product, the user may confuse the lamp cover and the door of the tool storage unit. Opening the lamp cover carelessly is dangerous because the lamp is hot immediately after use. Furthermore, when trying to store a small driver inside the product body, it hinders the design in consideration of the freedom of layout of internal parts and miniaturization. Although a storage method in which a tool is attached to the surface of the product main body without providing an opening / closing shape is conceivable, the appearance of the product appearance is greatly impaired. Further, if additional parts are required for storing the tool, it is disadvantageous in terms of cost and product assembly.

  An object of the present invention is to provide a storage structure for a small tool that is provided in an optical electronic apparatus and that allows a small tool to be easily taken out and that does not require special processing on a housing.
