A method for forming the document display device 1 from the forming material 10 will be described with reference to Figures 2 to 5. The formation of the document display device 1 from the forming material 10 includes the following steps 1 to 7. Before formation, the forming material 10 is in the state shown in Figures 2 and 3.

In the first step, the main surface portion 20 and the second side surface portion 32 are engaged. Specifically, the first engaging portion 40A of the main surface portion 20 and the second engaging portion 40B of the second side surface portion 32 are engaged. In the second step, the main surface portion 20 and the third side surface portion 33 are engaged. Specifically, the first engaging portion 40A of the main surface portion 20 and the second engaging portion 40B of the third side surface portion 33 are engaged. The first and second steps may be interchanged. FIG. 4 shows the state in which the second step has been completed. In the third step, the two second engaging portions 40B of the first side surface portion 31 are engaged with the first engaging portion 40A of the second side surface portion 32 and the first engaging portion 40A of the third side surface portion 33, respectively. The forming material 10 is formed into the state shown in FIG. 5.

In the fifth step, the fifth to seventh side portions 35 to 37 are moved forward. In the sixth step, the sixth side portion 36 is engaged with the second side portion 32. Specifically, the second engagement portion 40B of the sixth side portion 36 is engaged with the first engagement portion 40A of the second side portion 32. In the seventh step, the seventh side portion 37 is engaged with the third side portion 33. Specifically, the second engagement portion 40B of the seventh side portion 37 is engaged with the first engagement portion 40A of the third side portion 33. The sixth and seventh steps may be interchanged. After the seventh step is completed, the document display device 1 shown in FIG. 1 is formed.

The forming material 10 is configured to be changeable between a first state in which the support portion 3 is configured and a second state in which the support portion 3 is not configured. The change between the first state and the second state is performed by switching between an engaged state and a disengaged state of the first engaging portion 40A and the second engaging portion 40B. The first state is a state in which the support portion 3 can support the first mirror surface 2A and the second mirror surface 2B at a predetermined angle. In the document display device 1 in the first state, at least one of the first engaging portion 40A and the second engaging portion 40B is engaged.

The second state is a state in which the support portion 3 is not formed, and the main surface portion 20 and the mirror surface 2 provided on the main surface portion 20 are not supported at a predetermined angle. The change from the first state to the second state is performed, for example, by carrying out the assembly steps shown in Figures 4 and 5 in the reverse order. The second state includes a state in which the first engagement portions 40A and the second engagement portions 40B are all disengaged. In this case, it is the state shown in Figures 2 and 3, and the main surface portion 20 and the side surface portion 30 are formed in a flat shape.

As shown in FIG. 6, the mounting portion 4 corresponding to the opening 50 is provided with a folding piece 60. The folding piece 60 is configured to protrude toward the internal space when the document display device 1 is formed. When the document display device 1 is attached to the terminal D, the folding piece 60 at least comes into contact with the terminal D. Preferably, when the document display device 1 is attached to the terminal D, the folding piece 60 is pressed against the terminal D by the restoring force of the folding piece 60.

A method of using the document display device 1 will be described with reference to FIG.
The user prepares the manuscript M. The manuscript M may be written on paper and may be displayed on a terminal other than the terminal D on which the manuscript display device 1 is attached. The user can easily read out the manuscript M by reading the characters displayed on the first mirror surface 2A. The user can always properly display the manuscript M on the first mirror surface 2A of the manuscript display device 1 by shifting the manuscript M from one direction to the other direction. The display time of the displayed characters may be adjusted using a terminal other than the terminal D on which the manuscript display device 1 is attached. The imaging device C photographs the user with the user's line of sight facing the imaging device C. A viewer who sees the user photographed by the imaging device C recognizes that the user is speaking as if he or she is facing the user through the imaging device C, that is, without referring to the manuscript M. The viewer is, for example, a student attending a class or lecture of the user, and an interviewer of the user.

The document display device 1 of this embodiment and the function of the forming material 10 that forms the document display device 1 will be described. The document display device 1 is formed from the forming material 10 so that the main surface portion 20 and the side surface portion 30 are in a flat second state, and the document display device 1 is in a first state in which the first mirror surface 2A and the second mirror surface 2B attached to the main surface portion 20 are supported at a predetermined angle. The document display device 1 is attached to the attachment target via the attachment portion 4. At this time, the folding piece 60 is folded toward the internal space and attached. The attachment portion 4 and the folding piece 60 allow the document display device 1 to be stably fixed to the attachment target.

The document display device 1 and the forming material 10 forming the document display device 1 of this embodiment provide the following effects. The document display device 1 displays the document M in a normal state placed in front of the user in the normal state on the first mirror surface 2A. The normal state and the inverted state of the document M will be described. The normal state is a state in which the user does not have any problems reading the document M. The normal state includes a state in which the characters and figures contained in the document M are not inverted. The inverted state is a state in which the user has any problems reading the document M. The inverted state includes a state in which the characters and figures contained in the document M are inverted. The mirror surface 2 changes from one of the normal state and the inverted state to the other. The second mirror surface 2B of the document display device 1 reflects and displays the document M from the normal state to the inverted state. The first mirror surface 2A of the document display device 1 reflects and displays the inverted document M displayed on the second mirror surface 2B in the normal state. By providing the first mirror surface 2A and the second mirror surface 2B, the user does not need to place the document M in front of the user in an inverted state. This improves usability.

The length in the front-rear direction of the main opening 51 formed in the fourth side portion 34 of the forming material 10 is set to a range of 8 mm or more and 20 mm. This makes it easy to attach the document display device 1 to the terminal D, and prevents a gap from being formed between the terminal D and the mounting portion 4, thereby preventing light from entering the internal space from the mounting portion 4.

The vertical length of the side openings 52 formed in the second side portion 32 and the third side portion 33 is set to a range of 10 mm to 20 mm. Therefore, when attaching the document display device 1 to the terminal D, there is little risk that the document display device 1 will cover the display screen of the terminal D, and the user is unlikely to be prevented from viewing the display screen of the terminal D.

In the main surface portion 20 and the side surface portion 30, folds F are formed between each successive surface portion. This allows the forming material 10 to be folded in the second state. When the document display device 1 is not in use, the dimensions of the forming material 10 can be further reduced by making a valley fold at the folds F. This allows the forming material 10 to be stored, for example, in a small container, improving usability during storage or transport.
