The invention discloses an inner box of a tight packing box. The inner box comprises a base plate and a film arranged on the base plate; the base plate comprises a panel, a first support plate, a second support plate, a first support half body and a second support half body; the first support plate and the second support plate are symmetrically distributed on two opposite sides of the panel; the first support half body and the second support half body are symmetrically distributed on the other two opposite sides of the panel; the film coats the panel, the first support plate and the second support plate; a first folding mark is arranged between the first support plate and the panel; a second folding mark is arranged between the second support plate and the panel; a third folding mark is arranged between the first support half body and the panel; a fourth folding mark is arranged between the second support half body and the panel; the first support plate and the second support plate areboth downwards overturned relative to the panel; and the first support half body and the second support half body are both upwards overturned relative to the panel. The problems of complex corrugatedpaper packing structure, more used materials and low packing efficiency in the prior art are solved.

The invention relates to an electronic automatic recorder for certificates, which solves problems that existing information acquiring tools are image acquisition equipment such as scanners, cameras and the like which are connected with computers and have higher limitation, and image acquisition efficiency is reduced greatly due to the fact that the image acquisition equipment is connected with the computers in a wired manner. The automatic electronic recorder for certificates comprises a scanner, an electronic camera, a storage, a wire data transmission interface and an infrared adapter, wherein both the scanner and the electronic camera are connected with the storage, the storage is provided with the wire data transmission interface and the infrared adapter, and the scanner, the electronic camera and the storage are all arranged in a casing of the electronic automatic recorder.

A display device, especially a display device for displaying card-type pictures, the display device includes a casing and a light source device, the casing includes a slot structure, a transparent wall and a plurality of inner walls, the transparent The wall and the plurality of inner walls together form an accommodating space, the slot structure is arranged adjacent to the accommodating space, the slot structure has a transparent appearance wall, and the appearance wall and the transparent wall are arranged oppositely, and the light source device is located in the In the accommodating space, the light source device includes at least one light source and a light guide element, and the light source is arranged on one side opposite to the light guide element. The display device can clearly see the information on the display medium at night or when the light is dim, and the invention uses reusable transparent cards as the display medium, thereby saving paper resources.

The invention discloses a nine-lattice envelope which comprises a left base piece, a middle base piece, a right base piece, an upper left envelope piece, a lower left envelope piece, an upper middle envelope piece, a lower middle envelope piece, an upper right envelope piece and a lower right envelope piece. The right side edge of the left base piece is fixedly connected with the left side edge of the middle base piece, the left side edge of the right base piece is fixedly connected with the right side edge of the middle base piece, the upper edge of the left base piece is fixedly connected with the lower edge of the upper left envelope piece, the lower edge of the left base piece is fixedly connected with the upper edge of the lower left envelope piece, the upper edge of the middle base piece is fixedly connected with the lower edge of the upper middle envelope piece, the lower edge of the middle base piece is fixedly connected with the upper edge of the lower middle envelope piece, the upper edge of the right base piece is fixedly connected with the lower edge of the upper right envelope piece, the lower edge of the right base piece is fixedly connected with the upper edge of the lower right envelope piece, and a fold line is pressed at each connecting position. By means of the nine-lattice envelope, stamps are convenient to collect, paper resources are greatly saved, and at the same time, an envelope communication process of a specific transaction can be fully recorded on the same envelope.
