Description

  The present invention relates to a connecting structure capable of reversing the front and back in reverse by rotating one casing with another casing in an inverted state from the overlapping state, and also includes such a connecting structure. The present invention relates to an electronic information display device, and more particularly to an electronic information display device configured such that each side of a casing does not protrude from the overlapping surface of a second casing when re-superimposed.

Electronic information display devices, in particular portable electronic information display devices such as notebook computers and mobile phones, are generally used when the display panel for displaying images etc. is closed when facing non-use. In some cases, an opening / closing mechanism for opening the display panel from the main body is provided. By opening and closing using such an opening and closing mechanism, it protects the display panel from being damaged when not in use, prevents operation errors such as operation keys provided on the main body, and makes the device compact. It is easy to carry and can be operated while viewing the image displayed on the display panel during use. Many electronic information display devices provided with such an opening / closing mechanism have been disclosed (for example, see Patent Document 1).
JP 2005-166546 A

  However, some electronic information display devices having a conventional opening / closing mechanism have not been considered for downsizing. Such an electronic information display device increases in size when the display unit is opened 90 degrees or more during operation (during use). For example, when the display unit is opened 180 degrees, the combined area of the display panel and the main body is as follows. This is about twice that of the closed state. For this reason, for example, it was impossible to work in a narrow space on a desk in such a state. In addition, the operation on the palm of the hand may be difficult. In order to prevent the area of the device from increasing in such an open state, there is an electronic information display device having a fixed display panel. In this case, however, the display surface of the display panel is always provided. Since it is exposed, it may not be possible to achieve compactness in the closed state. In addition, there is a problem that it is impossible to protect the display panel so as not to be damaged or to prevent erroneous operation of an operation key provided on the main body portion.

  Also, in order to prevent the bottom area of the device from increasing when the display unit is turned upside down, the display unit is opened once in the horizontal direction (rotation direction with the center line connecting the center of the top and bottom of the display unit as the rotation axis) There is a type that allows the display unit to be superimposed on the main unit again after being reversed, but this opening operation requires three actions of “open, rotate, and close”. It has not been fully resolved. In addition, for the same purpose, there is a type that can be turned upside down by rotating the display unit about 360 degrees around the contact point between the display unit and the main unit. In this case, it is necessary to “carry” the display surface facing away from the user, so that the inconvenience of operation has not been fully resolved.

  Therefore, the problem to be solved by the present invention includes an open / close mechanism for closing the display panel so as to face the main body when not in use and opening the display panel from the main body when in use. Applicable to an electronic information display device, by rotating one casing with another casing in the direction of reversing the front and back by reversing the front and back, that is, simply “open (= turn)”.

<Overview>
The connection structure of the present embodiment is formed by connecting the first casing and the second casing, and the second casing is in a state where the second casing is overlapped with the first casing. The operation of rotating the front and back in the direction of reversing on the first housing and the operation of reversing the front and back of the second housing from the original overlapping state in reverse is there. Such a connection structure is used in an electronic information display device having an opening / closing mechanism for closing the display panel so that the display panel faces the main body when not in use and opening the display panel from the main body when using. Applicable.

<Configuration>
(Description of structure / Definition of terms)
FIG. 1 is a conceptual diagram illustrating an example of a configuration of a connection structure according to the present embodiment. The connection structure of the present embodiment is formed by connecting the first casing and the second casing, and the second casing is in a state where the second casing is overlapped with the first casing. Is configured to be linked to the operation of rotating the front and back of the second casing in reverse from the initial overlapping state. In the present invention, the “casing” refers to a container for storing equipment. As for the shape, a substantially rectangular parallelepiped shape is typically considered, but any shape may be used as long as the second housing can be overlapped with the first housing. In addition, in the following description, “state when not in use” and “when in use” are described according to the state. Here, the state when “not in use” means a state when the connection structure is not used. Say. This connection structure is formed by connecting the first casing and the second casing. The “second casing” refers to the casing that is used during use, and the “first casing” Indicates the casing that holds the second casing. For example, in the case of a desktop television of a type that is divided into a main body portion and a display portion and is used by opening the display panel from the main body at the time of use, the display panel corresponds to the second housing and the main body corresponds to the first housing. Further, the “state in use” means a state when the connection structure is used, and has a use surface of the second housing (for example, the display surface of the display panel in the case of the desktop TV in the above example). Indicates the state where the surface) appears on the front side. On the other hand, the time of non-use refers to a state where the use surface of the second housing appears on the side facing the first housing (in a flat state, the use surface is turned down). The term “use” as used herein refers to use as the original purpose so that “viewing” corresponds to this in the case of a desktop television. In this case, the “use surface” refers to a surface that appears on the front side in order to use it directly at the time of use (“view the TV screen” according to the above example). There is no problem in that the opening operation button used when performing (and therefore not in use) is provided on the surface when not in use.
First, Fig.1 (a) shows the state of the connection structure at the time of non-use. As shown in the figure, the connection structure of the present embodiment includes a first casing 0101 and a second casing 0102 superimposed on the first casing 0101, and the first casing and the second casing. The casings are connected by a connecting portion 0104. When using this connection structure, as shown in FIGS. 1B to 1H sequentially, the second casing 0102 is rotated in the reverse direction so that the front and back sides are reversed. Fix the second housing so that the usage surface of the second housing is on the front side. Accordingly, in the non-use state shown in FIG. 1A, the use surface 0102a appears as the back side, that is, the surface facing the first housing. In the example of FIG. 1, the connection part has a pivot support structure, and the second casing rotates in the direction of arrow A shown in FIG. As shown in FIG. 1 (h), the second casing rotates 180 degrees at the same time as the second casing rotates at the same time and the use surface 0102a is moved. Appears on the surface. That is, FIG. 1 (h) shows a state in use.

(Other configuration examples)
“Interlocking” in the present embodiment is not limited to the case where the rotation and horizontal movement of the second casing are performed simultaneously in parallel as in the example of FIG. It is a concept that includes the case where the other is made after that. Thus, the configuration may be such that after the completion of all or a part of one, the other is made. For example, in FIG. 2, first, the second housing moves horizontally in the direction of arrow B shown in FIG. 2 (a) to the state of FIG. 2 (b). An example of rotating 180 degrees in the direction of arrow A shown in FIG. 2 (b) without movement (FIG. 2 (c) shows a state rotated to 90 degrees in the middle, and FIG. 2 (d) shows a state rotated 180 degrees). . In contrast to this, in FIG. 3, first, the second casing rotates 180 degrees in the direction of arrow A shown in FIG. 3A without horizontal movement of the connecting portion (FIG. 4B shows 90 degrees in the middle). 3 (c) shows a state rotated 180 degrees), and then the second casing moves horizontally in the direction of arrow B shown in FIG. 3 (c). . In addition, the combination type in these cases, for example, the second casing is first rotated 90 degrees without horizontal movement of the connecting portion, and then the second casing is in a state of 180 degrees throughout the remaining period. You may make it move horizontally, rotating.

(Comparison between the two)
However, the connection structure shown in FIGS. 2 and 3 is generally simpler and less expensive to manufacture than the connection structure shown in FIG. For example, in the case of FIG. 1, as will be described in detail later, for example, a cylindrical gear and a linear gear (linear gear) are transmitted to transmit rotation, and the casing is moved horizontally along with the rotational movement (or horizontal A mechanism for rotating the housing as it moves is required, but in the examples of FIGS. 2 and 3, such a mechanism is not necessarily required, and a simply rotatable part or a slidable part is provided. Just do it. However, on the other hand, the connection structure shown in FIG. 2 and FIG. 3 is narrow because the second casing protrudes outside the first casing even if temporarily used, and the entire area increases. When opening and closing on the table, it is necessary to secure the space. In addition, the connection structure of FIG. 1 can flip the second casing upside down with only one action of “open (= turn)”, but the connection structure of FIG. 2 and FIG. To do this, two actions of “slide and turn” are required. However, since there is no need for troublesome operations such as “holding” like a conventional device that can be turned over by two actions, there is no change in that the front and back can be reversed and reversed with a simple operation. Thus, both the connecting structure as shown in FIG. 1 and the connecting structure as shown in FIGS. 2 and 3 have their respective characteristics, so that the front and back sides are reversed by rotating the second casing in the reverse direction. It is an appropriate design matter for a person skilled in the art to take into consideration the manufacturing cost and the usage situation of the connection structure, in particular, what configuration is taken as the configuration for re-superimposing the connection structure.

  Such a connection structure includes an electronic information display device (for example, a desktop TV / video, a mobile phone, a game machine, an electronic dictionary) provided with an opening / closing mechanism for opening a display panel described later from the main body. It can be widely applied to notebook computers and the like, and is particularly useful for devices that have many opportunities to be used on a small desktop. FIG. 4 is an example of the external appearance of an electronic information display device to which such a connection structure is applied, and is a view showing the external appearance when not in use. FIG. 5 is an example of the appearance of another electronic information display device to which such a connection structure is applied, and also shows the appearance when not in use. In FIG. 4, a hatched portion is the first housing 0401, and a portion overlaid thereon is the second housing 0402. Although not shown, the connecting portion is embedded inside the casing on one side that appears on the right side of the second casing, and the second casing rotates in the direction of arrow A while the arrow B. It is structured to move horizontally in the direction. The above also applies to FIG.

<Effect>
According to the present embodiment, the operation of rotating the second casing in the reverse direction on the first casing from the state in which the second casing is superimposed on the first casing, and the initial overlapping state From the above, it is possible to provide a connection structure that is configured so that the operation of reversing the front and back of the second casing in reverse is linked, and this is closed in a manner that the display panel faces the main body when not in use, In use, the display panel can be applied to an electronic information display device having an opening / closing mechanism for opening the display panel from the main body.

<Overview>
The connection structure of this embodiment is basically the same as that of the first embodiment. However, the connecting portion between the first casing and the second casing is characterized in that it horizontally moves with respect to the overlapping surface of the first casing in accordance with the rotation operation. Moreover, the connection part is preferably a shaft support connection structure.

<Configuration>
(Definition of features and terms of composition)
An example of the connection structure of the present embodiment is the same as that shown in FIG. That is, the connection structure 0100 of the present embodiment rotates the second casing in the reverse direction from the state in which the second casing 0102 is superimposed on the first casing 0101 on the first casing. It is the connection structure comprised so that the operation | movement to perform and the operation | movement which reversely superimposes the front and back of a 2nd housing | casing reversely from the initial overlapping state. However, in the connection structure of this example, the connection portion 0104 between the first housing and the second housing moves horizontally with respect to the overlapping surface 0102a of the first housing in accordance with the rotation operation (FIG. 1). Then, it moves in the direction of arrow B). In addition, as shown in FIG. 1, it is desirable that the connection portion has a pivot connection structure that rotates the second housing around one side of the second housing. “The connection part of the first casing and the second casing moves horizontally with respect to the overlapping surface of the first casing according to the rotation operation” means that the second casing is connected to this connection part. , And the connection part moves horizontally throughout the entire rotation, and the second casing rotates 180 degrees and at the same time, the front and back inversion is completed and the use surface is the surface. To appear in

(Specific configuration according to features (1) Connection site)
Next, a specific configuration for realizing horizontal movement according to the rotation operation, which is a feature of the present embodiment, will be described. Here, first, the configuration of the connected portion will be described. FIG. 6 is a schematic diagram for explaining an example of a configuration for realizing horizontal movement according to the rotation operation of the connection structure according to the present embodiment. This figure is a side view of the second housing of the device in order to explain the structure of the connection part and the like in the example of the electronic information display device shown in FIG. 4 as a specific example of the connection structure of this example. The cover is removed so that a part of the interior can be seen. The connection part of this example forms a shaft (not shown in the figure) that forms a shaft support connection structure, and has a gear 0606 (referred to as “A gear” in this embodiment) that shares a rotation axis with itself at the tip. . This A gear is formed integrally with the shaft or fitted and fixed to the shaft, and always rotates at the same rotational speed as the rotation of the shaft forming the shaft support connection structure. FIG. 7A is a diagram illustrating an example of the shape of the shaft 0704 that forms the shaft connection structure that is the connection portion of this example and the A gear 0706 that is held at the tip thereof, in the same example as FIG. FIG. 7B is a view showing an example of the shapes of the shaft 0704 and the A gear 0706 that similarly form the shaft connection structure, and the shaft that forms the shaft connection structure that is the connection portion of FIG. And viewed from a different direction (generally, the right direction in FIG. 7A). As apparent from the comparison between FIG. 6 and FIG. 7, this axis is arranged in a form embedded in the second housing 0602, and this is why it does not appear in FIG. 6. FIG. 8 shows the shaft 0804 and the like that form an internal support connection structure by further removing the upper cover of the second housing and the side cover of the first housing from the connection structure shown in FIG. 6 for reference. It is the figure which showed the state which can be seen.

Next, as shown in FIG. 8, the A gear 0806 and the shaft 0804, which forms a shaft support connection structure, are divided into a bearing portion (upper) 0812 and a bearing portion (lower side) (shown in the figure). (Omitted) are rotatably held by two bearing portions. Among the shafts and the like forming the shaft connection structure shown in FIG. 7, 0704a (the portion indicated by hatching) is a portion that is directly held by the above-described bearing portion. The shape of the remaining portion 0704b is not a cylindrical shape in this example, but a shape in which a flat plate is added thereto. This is because the connection portion embedded in the second housing is rotated along with the rotation of the second housing. This is to make the shape easy to achieve the rotation mechanism of rotating together and the A gear at the tip of the gear rotating at the same rotational speed, and the specific shape is an appropriate design matter for those skilled in the art.
In addition, in this figure, although the axis | shaft which makes a shaft connection structure appears also on the side surface on the opposite side, this may not be necessary. However, in order to smoothly rotate and horizontally move the second casing, it is desirable to have structures on both sides as shown in the figure. The above points are the same for the shafts, the display rotation shafts, and the first and second housing side slide portions that form the shaft support connection structure in the other embodiments.
FIG. 9A shows an example of the shape of a constituent member including a bearing portion (lower side) 0911 (specifically, a member in which the bearing portion and another bearing portion 0911b described later are integrally formed). FIG. FIG. 9B is a view showing an example of the shape of the bearing portion (upper side) 0912. FIG. 9C is a view showing an example of a state in which the bearing portion shown in FIG. 9A and the bearing portion shown in FIG.

(Purpose of configuration)
As described above, one of the features of the connecting portion of the connecting structure of the present example is that the bearing portion can be divided and fixed in the radial direction of the shaft. This is because each of the two divided bearing portions is sandwiched while pressurizing the shaft, and a rotational friction force is applied to the shaft. Specifically, for example, the radial receiving surface 0911a of the bearing portion (lower side) 0911 and the radial receiving surface 0912a of the bearing portion (upper side) 0912 shown in FIG. A configuration to be added is conceivable. For example, the inner diameter of the bearing portion formed when the upper and lower portions of the bearing portion are closely aligned without clamping the shaft is designed to be slightly smaller than the diameter of the shaft to be clamped. Then, the shaft is sandwiched between the divided bearing portions, and both the bearing portions are fastened with screws or the like. It is possible to adjust the opening / closing torque (rotational frictional force) of the coupling structure by controlling the load that the shaft receives from the bearing portion with the tightening torque of the screw. Alternatively, a predetermined opening / closing torque may be generated by an assembling method with dimensional accuracy calculated and designed in advance. In short, it is sufficient that the bearing portion is configured to generate a contact pressure sufficient to hold the second housing at a predetermined angle in the radial direction between the shaft and the bearing portion when the bearing portion is fixed. It is an appropriate design matter.

(Specific structure according to features (2) Second housing)
Returning to FIG. 8, the second housing further has another gear (referred to as “B gear” in this embodiment). The B gear is for transmitting the rotation of the A gear to the fixed rack gear, and includes a large gear 0807a and a small gear (not shown). The large gear and the small gear share a rotation axis. FIG. 10A is a diagram illustrating an example of the shape of the B gear 1007. Of these, 1007a is a large gear and 1007b is a small gear. FIG. 10B is a view showing an example of the appearance of the B gear 1007, as seen from a direction different from (a) (the side of the small gear 1007b).

(Specific structure according to features (3) First case)
On the other hand, in FIG. 8, the first housing 0801 has a fixed rack gear 0810. The fixed rack gear is fixed horizontally to the first housing and has a structure that does not move. FIG. 11 is a diagram illustrating an example of the shape of the fixed rack gear 1110.

(Component layout)
FIG. 12 shows the relative positional relationship between a shaft 1204 (having an A gear 1206 at the tip), a B gear 1207 (consisting of a large gear 1207a and a small gear 1207b), and a fixed rack gear 1210, which form a shaft coupling structure as a coupling part. FIG. As shown in this figure, the small gear of the B gear is arranged so as to mesh with the A gear, and the large gear of the B gear is arranged so as to mesh with the fixed rack gear. Since the small gear and the large gear share the rotation axis, as a result, the rotation of the shaft that forms the shaft connection structure that is the connection portion is transmitted in the order of the A gear, the B gear small gear, and the B gear large gear. The large gear moves horizontally on the fixed rack gear fixed horizontally to the first casing in the direction of arrow B in FIG. 6, and the connecting portion and the second casing also move horizontally in the direction of arrow B accordingly. Is realized. Or, conversely, while the large gear of the B gear rotates and moves horizontally on the fixed rack gear in the direction of the arrow B, this rotation is transmitted in the order of the small gear of the B gear, the A gear, and the shaft that forms the shaft support connection structure. The same operation may be realized. In general, when the operation is realized by motor driving, the B gear serves as a gear for transmitting the driving force of the motor, and the rotation of the B gear by this driving is transmitted to the A gear, so the latter transmission order. On the other hand, when the second casing is manually opened, the former transmission order is used. Which configuration is used is an appropriate design matter for those skilled in the art. The following description will be mainly given in the case of the former transmission order, but the reverse order is not excluded.

  Since it is configured and arranged as described above, as shown in FIG. 8, when the opening operation is performed in the direction of arrow A around the shaft 0804 that forms the pivot connection structure in which the second casing 0802 is a connection part, An operation of horizontally moving the second casing while rotating is realized by rotating an axis or the like embedded in the second casing. This configuration and arrangement relationship will be described in detail with reference to FIG. 12. The arrow A direction in FIG. 8 appears as the arrow A direction in FIG. 12, but the second casing (not shown) opens in this direction. As a result, the shaft 1204 embedded in the second casing rotates in the A direction, and the A gear 1206 fixed to the tip of the shaft 1204 also rotates in the arrow C direction at the same rotational speed. Then, the rotation of the A gear is transmitted to the small gear 1207a of the B gear which meshes with it, and the small gear and the large gear 1207b of the B gear sharing the rotation axis with the small gear rotate in the direction of arrow D. 1210 is moved horizontally in the direction of arrow B. Thereby, the operation | movement which moves horizontally while rotating the 2nd housing | casing is implement | achieved.

(Other arrangement examples of component parts)
In the above description, the rotation of the connecting portion is transmitted via the two cylindrical gears (the A gear directly provided at the connecting portion and the B gear directly meshing with the linear gear) and the linear gear through the second casing. However, the A gear does not directly transmit the rotation to the B gear, but further includes one or more gears between the A gear and the B gear. You may make it transmit rotation through these. In order to cover the relatively inferior point in terms of strength when the gear shape is the most general spur gear in terms of cost, for example, the gears are further interposed in this way. The purpose is to reduce the load on the gears and the like.

<Effect>
According to this embodiment, when the second casing is rotated in the reverse direction, the rotation of the connecting portion is rotated by transmitting the rotation of the shaft via the shaft that forms the shaft support connection structure and the gear connected to the shaft. Accordingly, the opening / closing operation can be smoothly performed because the first casing can be horizontally moved with respect to the overlapping surface.

<Overview>
The connection structure of the present embodiment is basically the same as that of the apparatus of the second embodiment, but the shaft that forms the shaft support connection structure is the first that faces this side from one side of the first housing in accordance with the rotation operation. It is characterized in that it moves to the opposite side of one casing.

<Configuration>
(Configuration features, definition of terms, and specific configurations related to features)
FIG. 13 is a conceptual diagram illustrating an example of the configuration of the connection structure according to the present embodiment. FIG. 13 is a perspective view illustrating the same structure as that illustrated in FIG. Hereinafter, based on FIG. 13, which is a feature of the connection structure of the present embodiment, “the shaft that forms the shaft support connection structure is a first case that faces this side from one side of the first case in accordance with the rotation operation. A specific configuration for realizing “moving to the opposite side of the body” will be described. Here, “one side of the first casing” refers to either one of the two sides 1301a and 1301b indicated by a thick line (solid line or broken line) in FIG. The “opposite side” means the remaining one of the two sides. In the following description, “one side of the first casing” is 1301a, and “opposite side of the first casing facing this side” is 1301b. In this case, the “one side of the first casing” refers to a range indicated by 1301c, that is, a range that substantially overlaps the side 1301a in the second casing. The “opposite side of the first casing facing this side” refers to a range indicated by 1301d, that is, a range that generally overlaps above the side 1301b in the second casing. Therefore, the shaft 1304 that forms the shaft connection structure moves horizontally in the direction of arrow B from the position 1301c to the position 1301d in accordance with the rotation operation. The meaning of “according to the rotation operation” is the same as that in the second embodiment. That is, the second housing rotates around this connection part as the center of rotation, the connection part moves horizontally throughout the rotation, and the second case rotates 180 degrees. At the same time, it means that the reverse side is completed and the use surface appears on the surface. As a result, when using this connection structure, the second housing 1302 rotates in the direction of arrow A about the axis that forms the shaft connection structure that is the connection part, and the connection part is It moves horizontally in the direction of arrow B throughout the entire period of rotation, and as shown in FIG. 13 (d), it moves to the position 1301d when in use. FIGS. 13B and 13C show states in the middle from (a) to (d). Since the remaining configuration is the same as that described in the second embodiment, the description thereof is omitted. Since this figure is a conceptual diagram for explaining the mechanism of movement as described above, the appearance and shape of the shaft that forms the housing and the shaft connection structure are simplified, but in actuality, The specific shape in the case where the connection structure is applied to an electronic information device is an appropriate design matter. For example, the case or the shaft support connection structure shown in FIGS. The appearance and shape of the shaft is an example. Further, in this drawing, the shaft forming the shaft support connection structure is drawn so as to exist only on one side, but it may also exist on the opposite side surface on the extension line of this shaft.

  Furthermore, in the above description, the case where the bottom areas of the first housing and the second housing are equal (that is, the second housing exactly overlaps the first housing) is described in mind. did. However, the connection structure of the present embodiment is not limited to such a structure, and at least one of both sides of the second housing may be located inside the side of the first housing. Good. FIG. 14 is a perspective view showing such an example (FIG. 14A shows a non-use state and FIG. 14B shows a use state). Furthermore, contrary to the above, at least one of both sides of the second casing may be located outside the side of the first casing. FIG. 15 is a perspective view showing such an example (FIG. 15A shows a non-use state and FIG. 15B shows a use state). Thus, even when the bottom area of the second casing is larger than the bottom area of the first casing, it is suitable for the purpose of the present invention to not increase the bottom area of the apparatus when the front and back are reversed. There is no problem in using it.

<Effect>
According to this embodiment, when rotating the second housing in the front and back inversion direction, the connection part can be moved from one side of the first housing to the opposite side according to the rotation operation, One surface of the second housing can be used as the front surface when in use while being protected as the back surface when not in use.

<Overview>
The connection structure according to the present embodiment is basically the same as that of any one of the first to third embodiments. However, the connection in the connection structure of this example is characterized in that each side of the second casing is prevented from protruding from the overlapping surface of the first casing by the re-overlap.

<Configuration>
(Specific features related to the features and features)
FIG. 16 is a conceptual diagram illustrating an example of the configuration of the connection structure according to the present embodiment. The same structure as that illustrated in FIG. 1 for the first embodiment is represented by a plan view and a front view. is there. Here, “the connection in the connection structure is a feature of the connection structure of the present embodiment, so that each side of the second housing does not protrude from the overlapping surface of the first housing due to the re-overlap. Will be explained. As described above, the “second casing” refers to the casing that is used during use. There are a plurality of modes in which “the connection in the connection structure is such that each side of the second casing does not protrude from the overlapping surface of the first casing by the re-superposition”. In one embodiment, as shown in FIG. 13, the bottom areas of the two casings are the same, and the second casing is placed on the first casing when not in use and in use. This is the case when they overlap exactly. When this state is seen in a plan view, each side of the second casing appears at the same position as each side of the first casing. FIG. 16A is a plan view showing a non-use state, and FIG. 16B is a front view showing the same state. At this time, one side 1601a of the first housing 1601 and one side 1602b of the second housing 1602 appear at the same position on the plan view (position indicated by a thick line 1602b in FIG. 16A). . Similarly, both sides of the opposing side of the first casing and the opposing side of the second casing appear at the same position 1602c. Next, FIG.16 (c) is a top view which shows the state at the time of use, (d) is a front view which shows the state. That is, in the state of use in which the second casing is turned upside down, as shown in these drawings, the side 1601a of the first casing and the side 1602c of the second casing are on the plan view. It appears at the same position (position indicated by a thick line 1602c in FIG. 16C). Further, the opposite side of the first casing and the side 1602b of the second casing appear at the same position on the plan view (the position indicated by the thick line 1602b in FIG. 16C). As for two sides adjacent to these sides, the side of the first housing and the side of the second housing appear at the same position 1602d and 1602e on the plan view when not in use and when used. Eventually, in this case, the first casing and the second casing are exactly the same size and overlap exactly in the front, rear, left, and right (even when not in use and in use).

(Other specific configuration examples)
Another aspect is a case where the side of the second casing is located on the inner side of the side of the first casing with respect to at least one side. For example, as shown in FIG. 14, when one side 1402b of the second housing 1402 is located inside the one side 1401a of the first housing 1401, FIGS. ) Are a plan view and a front view showing a state when not in use in such a case, and FIGS. 17C and 17D are a plan view and a front view showing a state when in use. In this case, in the plan views (a) and (c), one side 1702b of the second casing appears inside one side of the first casing (as a result, a part of the upper surface of the first casing 1701). Will appear on the floor plan). In this case, unlike the case of FIG. 16, it is not essential that one side comes to the same position as the position when the opposite side is not used when the second casing is turned upside down (see FIG. 16). 17 (c) also shows an example in which one side 1702b does not come to the position 1702c ′ when the opposite side is not used, unlike the example of FIG.

(Purpose of configuration)
The configuration as described above is such that the bottom area of the connecting structure during use does not increase more than that during non-use, so that even in a narrow space, the bottom area occupied by the connection structure when not in use ( That is, an object is to enable the use of the structure as long as the bottom area of the first housing can be secured. As a specific example, when the connection structure is applied to an electronic information display device (particularly, a portable terminal such as a mobile phone), the size of the device when the display surface is used is changed to the main body (first) It becomes easy to operate on the palm of your hand. That is, the display function can be used in a compact manner without increasing the area of the entire apparatus by turning over only the display portion while holding the terminal body with one hand. Note that the second casing is only required to prevent the bottom area of the device from being increased when the second casing is turned upside down (that is, the bottom area may be temporarily increased during the opening / closing operation). It is also conceivable that the terminal device may be a terminal device in which the rotating portion of the body does not slide and rotates about 360 degrees and the opposite surface of the first housing is the display surface. However, in this case, it is necessary to change the terminal body and use the display surface. In contrast, in this embodiment, the display unit can be smoothly shifted from the closed state to the opened state without changing the terminal body. Furthermore, if the connecting portion as described in the second embodiment is a device of a type that moves horizontally with respect to the overlapping surface of the first housing in accordance with the rotation operation, the device can be temporarily connected during the opening / closing operation. Since the bottom area does not increase, it can be easily used by performing an opening / closing operation while being placed on a narrow tabletop.

<Effect>
According to this embodiment, since the bottom area when the electronic information display device is used can be prevented from increasing more than when the electronic information display device is not used, even the bottom area occupied by the device when not in use is ensured even in a narrow space. If possible, the device can be used, and for example, the portable terminal can be easily operated on the palm of the hand.

<Overview>
The electronic information display apparatus according to the present embodiment is an electronic information display apparatus including the connection structure described in any one of the first to fourth embodiments. It has the display surface for displaying.

(Definition of features and terms of composition)
FIG. 18 is a diagram showing an example of an external appearance of an electronic information display device similar to that shown in FIG. 5 and having a display surface 1802a in the second casing 1802. This figure shows a state in which the second casing is moving horizontally in the direction of arrow B while rotating in the direction of arrow A in order to use the apparatus. In addition, since this figure has shown the state seen from the side opposite to FIG. 5 so that a display surface may appear in the figure, the arrow A direction and the arrow B direction appear in the opposite direction to FIG. Yes. This figure shows a state in which the second casing is rotated 180 degrees and turned upside down, and is rotated about 135 degrees and moved horizontally by a distance corresponding thereto. Thereafter, when the second casing further rotates about 45 degrees in the direction of the arrow A ′, the front / back inversion is completed, and the second casing is overlapped with the first casing 1801 with the display surface facing front. “Any overlapping surface” means that the overlapping surface with the first housing is reversed when not in use and when in use, and therefore means one of the overlapping surfaces. Means the overlapping surface (back surface) when not in use, and thus the surface when in use. The display is preferably a flat panel display. In this case, the display type may be a liquid crystal display, a plasma display, or the like, but may be other than these.

(Purpose of configuration)
The above configuration is configured so that the display surface is a superimposed surface when not in use so that the display surface is not damaged, and the display surface is inverted to be a surface when in use. It is intended to make it possible to display and use electronic information. As such an electronic information display device, for example, a desktop television / video, a mobile phone, a game machine, an electronic dictionary, a notebook personal computer, and the like are conceivable.

<Effect>
According to the present embodiment, it is possible to provide an electronic information display device to which the connection structure described in the first to fourth embodiments is applied, and the electronic information display device can be easily operated even in a narrow space. .

<Overview>
The electronic information display apparatus according to the present embodiment is basically the same as the apparatus according to the fifth embodiment. However, the electronic information display apparatus includes a set of slide units (first housing) that move the connection portion from one side of the first housing to the opposite side. (The body side slide part, the second case side slide part), and the display rotation shaft, the second case side slide part, and the first case side slide part have gears, respectively, and the rotation is transmitted by these. It is characterized in that the rotation and horizontal movement of the second casing are realized, and that the gears included in the display rotation shaft and the second casing side slide portion are all spur gears.

<Configuration>
(Outline of components)
FIG. 19 is a diagram illustrating an example of the external appearance of the component relating to the rotation and horizontal movement of the second casing in the electronic information display apparatus according to the present embodiment, and among the electronic information display apparatus illustrated in FIG. The upper part of the second housing 0502, the cover part on the side surface, and the like are removed so that a part of these components can be seen. These components are roughly classified into a display rotation shaft 1904, a second housing side sliding portion, and a first housing side sliding portion. The display rotation shaft 1904 has a first gear 1906 at its tip. The second housing side slide portion includes a second gear 1927, a third gear 1926, a fourth gear 1907 and a slide plate 1908. The first housing side slide portion has a fixed rack gear 1910 and a chassis side plate 1909. Further, as is apparent from a comparison between FIG. 5 and FIG. 5, the display rotation axis is disposed so as to be embedded in the second casing. Therefore, when the second casing opens, the display rotation shaft also rotates together with the first gear.

(Relationship between components (1) meshing relationship)
FIG. 20 is a diagram for explaining the meshing relationship between these gears. First, the first gear 2006 meshes with a small gear (not shown in the drawing) of the second gear 2027. The large gear 2027 a of the second gear sharing the rotation axis with the small gear meshes with the small gear 2026 b of the third gear 2026. The large gear 2026a of the third gear sharing the rotation axis with the small gear meshes with the small gear 2007b of the fourth gear 2007. The large gear 2007a, which is the fourth gear sharing the rotation shaft with the small gear, meshes with the fixed rack gear 2010 (partially omitted).
FIG. 21 is a view for similarly explaining the meshing relationship of the gears, and is a view seen from an angle different from FIG. 20 (generally slightly diagonally downward to the right). This figure shows the meshing relationship between the first gear 2106 and the small gear 2127b of the second gear 2127, which is not shown in FIG.

(Relationship between components (2) Rotational transmission relationship)
Returning to FIG. 19, the rotation transmission relationship between these components will be described next. As a premise thereof, although omitted in FIGS. 20 and 21, as shown in FIG. 19, the second gear 1927, the third gear 1926, and the fourth gear 1907 are gear shafts planted on one slide plate 1908. 1913a-c is rotatably fitted. FIG. 22 shows an example similar to the one shown in FIG. 19 as an example of the shape of the slide plate. Three gear shafts 2213a to 2213c are planted on the slide plate 2208. Of these, 2213a is for the second gear, 2213b is for the third gear, and 2213c is for the fourth gear.
Therefore, the rotational transmission relationship between these components is as follows. Here, the description will be given in the order that the rotation is sequentially transmitted from the display rotation shaft to the first, second, third, and fourth gears. This is because it is suitable for the operation of opening the housing and putting it into a state of use. However, the configuration of the present embodiment does not exclude the case where the rotation of the fourth gear is sequentially transmitted to the third, second, first gear, and display rotation shaft. In other words, the second gear is a gear that transmits the rotation of the display rotation shaft, and the third gear is a gear that transmits the rotation of the second gear. Alternatively, the expression “the fourth gear is a gear to which the rotation of the third gear is transmitted” is used in a sense including transmission by both of the above transmission orders.

  Therefore, as shown in FIG. 20, when the display rotation shaft 2004 is rotated in the direction of arrow A, the first gear 2006 at the tip is also rotated in the C direction (the same clockwise direction as the A direction), and the second gear meshing therewith. The small gear 2027b of 2027 rotates in the arrow D direction (counterclockwise direction). Then, the large gear 2027a of the second gear sharing the rotation axis with the small gear also rotates in the D direction, and the small gear 2026b of the third gear 2026 that meshes with the large gear 2027a rotates in the E direction (clockwise direction). Then, the large gear 2026a of the third gear sharing the rotation axis with the small gear also rotates in the E direction, and the small gear 2007b of the fourth gear 2007 that meshes with the small gear 2007b rotates in the F direction (counterclockwise direction). Then, the large gear 2007a of the fourth gear sharing the rotation shaft with the small gear also rotates in the F direction. Since the large gear meshes with the fixed rack gear 2010, the large gear moves horizontally in the arrow B direction. Since the fourth gear is held by the gear shaft planted on the same slide plate as the second and third gears as described above, the slide plate is moved to the second gear as the fourth gear moves horizontally. The horizontal movement in the B direction together with the third gear (more specifically, the slide plate is guided in the guide groove of the chassis side plate provided on the side surface of the first housing and horizontally moved in the B direction. Will be described later). As a result, the display rotating shaft having the first gear meshing with the second gear also horizontally moves in the B direction. The rotation angle at this time is such that the fourth gear moves from the rearmost end to the frontmost end in the depth direction on the track of the fixed rack gear while the first gear rotates 180 degrees. The gear ratio of each gear is set. As described above, it is possible to realize an operation in which the display rotation axis rotates in the A direction and moves horizontally in the B direction, that is, an operation in which the horizontal movement is completed simultaneously with the end of the front / back inversion.

(Description of each component (1) Display rotating shaft and first gear)
Here, an example of the shape of each component of a display rotating shaft and a 2nd housing | casing side slide part is shown. First, FIG. 23 shows an example of the shapes of the display rotation shaft 2304 and the first gear 2306. As shown in the figure, the first gear of this example is a spur gear. The example of this figure is an example of the components of the electronic information display device shown in FIG. 5. Therefore, the electronic information display device shown in FIG. 4 (the number of cylindrical gears is two, unlike the four in this example). As an example of the component, the shaft that forms the shaft connection structure shown in FIG. 7 and the example of the A gear are different in shape (particularly the shape of the shaft that forms the shaft connection structure). The function of rotating at the same rotational speed as the shaft (shaft that forms the shaft support connection structure) and transmitting the rotation to other gears is the same. The display rotating shaft and the first gear of this example are shown in FIG. This corresponds to a shaft and an A gear that form a shaft support connection structure. Accordingly, in the same manner as described above with respect to the shaft and the A gear that form the shaft support connection structure, these specific shapes also rotate together with the display rotating shaft embedded in the second casing, As long as it is easy to achieve the rotation mechanism that the tip gear rotates at the same rotational speed, it may have other shapes, and is an appropriate design matter for those skilled in the art.

(Description of each component (2) Second housing side slide part, second gear)
24 shows an example of the shape of the second gear 2427 ((a) is a view seen from the front, and (b) is a view seen from the right side. The same applies to FIGS. is there). Of these, 2427a is a large gear and 2427b is a small gear. As shown in this figure, the second gear of this example is a spur gear for both the large gear and the small gear. When the rotation of the first gear is transmitted to the small gear meshing with the second gear, the second gear rotates in the opposite direction to the first gear, and the large gear sharing the rotation axis with the small gear rotates to rotate the second gear. It is for transmitting to the three gears. Therefore, the specific shape is an appropriate design matter for those skilled in the art as long as such a function can be achieved.

(Description of each component (3) Second housing side slide part, third gear)
FIG. 25 shows an example of the shape of the third gear 2526. Of these, 2526a is a large gear and 2526b is a small gear. As shown in the figure, the third gear of this example is a spur gear for both the large gear and the small gear. The third gear rotates in the opposite direction to the third gear when the rotation of the second gear (large gear) is transmitted to the small gear meshing with the second gear, and the large gear sharing the rotation axis with the small gear rotates. This is to transmit this to the fourth gear. Therefore, the specific shape is an appropriate design matter for those skilled in the art as long as such a function can be achieved.

(Description of each component (4) Second housing side slide part, fourth gear)
FIG. 26 shows an example of the shape of the fourth gear 2607. Of these, 2607a is a large gear and 2607b is a small gear. As shown in the figure, the third gear of this example is a spur gear for both the large gear and the small gear. The third gear rotates in the opposite direction to the third gear when the rotation of the third gear (large gear) is transmitted to the small gear meshing therewith, and the large gear sharing the rotation axis with the small gear rotates. This is to transmit this to the fourth gear. Therefore, the specific shape is an appropriate design matter for those skilled in the art as long as such a function can be achieved.

(Explanation of each component (5) Second casing side sliding part / slide plate and first casing side sliding part / chassis side plate)
As shown in the example of the shape in FIG. 22, a gear shaft for rotatably fitting the second, third, and fourth gears is planted on the slide plate. The function of the slide plate is to hold the second, third and fourth gears by such a structure and to move horizontally by being guided by the guide groove of the chassis side plate provided on the side surface of the first housing. Is to horizontally move the display rotation axis. Here, details of the shape of the slide plate and a specific configuration for horizontal movement will be described. For convenience of explanation, the chassis side plate of the first housing will also be described here.

FIG. 27 shows the slide plate of the shape example shown in FIG. 22 in a state where the back surface can be seen from another angle. As shown in FIG. 27 (a), slide shafts 2721a to 2721c are inserted and fitted at three positions on the rear surface of the slide plate 2708, and the chassis side plates are connected to the chassis side plates by E-rings 2722a to c through guide grooves of the chassis side plates not shown. Mounted freely. Reference numerals 2713a to 27c denote gear shafts that are fitted and fixed to the slide plate so as to penetrate the back surface. FIG. 27B shows the E-rings 2722a-c separated from the slide shafts 2721a-c for reference.
FIG. 28 shows an example of the shape of the two guide grooves 2809a and 2809b provided in the chassis side plate 2809, which is a part 2801 of the first housing, and FIG. 29 shows the slide plate 2808 moving to the chassis side plate 2909. An example of the state attached freely is shown. In this example, one slide shaft 2921a is inserted and fitted into the upper groove, and the other two slide shafts 2921b and c are attached to the lower groove so as to be freely movable by an E-ring. FIG. 30 shows the chassis side plate 3009 and the guide grooves 3009a and 3009b provided therein viewed from the back side, and 3022a to 30c are E-rings. With the configuration described above, the fourth gear fixed to the gear shaft of the slide plate moves horizontally on the fixed rack gear, so that the slide plate also moves horizontally along the guide groove, and the display rotates through the mechanism described above. A shaft opening / closing operation is realized.

(Explanation of each component (6) Sliding part on the first casing and fixed rack gear)
Next, components of the first housing side slide part will be described. Among these, since the chassis side plate has already been described, the fixed rack gear will be described here. FIG. 31 is a diagram illustrating an example of the shape of the fixed rack gear 3110. As shown in the figure, the fixed rack gear is a linear gear, and the fourth gear meshing with the fixed rack gear moves horizontally on the fixed gear to enable the opening / closing operation of the display rotation shaft described above.

(Purpose of configuration)
As described above, the four gears of the first gear, the second gear, the third gear, and the fourth gear are sequentially meshed. Spur gears are the most widely used gears that are easy to machine and are mass-produced. Therefore, it is an object to make it possible to relatively reduce the manufacturing cost and repair cost of the present apparatus at a low price. On the other hand, the spur gear has a relatively weak transmission force and a large load on the gear compared to the helical gear described in the next embodiment, but in this example, this problem can be solved by increasing the number of gears and distributing the load. Has solved.

<Effect>
According to the present embodiment, it is possible to smoothly realize the rotation and horizontal movement of the display rotation shaft of the electronic information display device having the display surface. Further, since the first, second, third, and fourth gears are all spur gears, it is possible to keep the manufacturing and repair costs of the present apparatus relatively low.

<Overview>
The electronic information display apparatus according to the present embodiment is basically the same as the apparatus according to the fifth embodiment, but (1) a set of slide portions that move the connecting portion from one side of the first housing to the opposite side ( (2) The display rotation shaft, the second housing side slide portion, and the first housing side slide portion each have a gear, and the rotation is transmitted by these. The rotation and horizontal movement of the second casing is realized by this, and (3) the gears of the display rotating shaft and the second casing side slide portion are the helical gear, worm gear, and spur gear. It is characterized in that it is a combination. Therefore, the present embodiment has the same characteristic points as the embodiment 6 with respect to the points (1) and (2), while the display rotating shaft / second housing side slide portion of the embodiment 6 has the point (3). It is characterized in that the type and number of gears are replaced.

<Configuration>
(Outline of components)
FIG. 32 is a diagram illustrating an example of the external appearance of a component relating to rotation and horizontal movement of the second casing in the electronic information display apparatus according to the present embodiment. Similar to the sixth embodiment, these components are roughly classified into a display rotation shaft 3204, a second housing side sliding portion, and a first housing side sliding portion. The point that the display rotation shaft has the first gear 3206 at the tip thereof is the same as in the sixth embodiment. However, the number of gears included in the second housing side slide portion is different from that in the sixth embodiment. That is, the second housing side slide part of the sixth embodiment has three gears from the second to the fourth, whereas the second housing side slide part of the device of this example has only the fifth gear 3228. . The fifth gear has a small gear 3228b and a large gear 3228a. The first housing side slide portion has a fixed rack gear 3210 and a chassis side plate 3209 as in the sixth embodiment. The chassis side plate has two guide grooves 3209a and 3209b. The first gear is configured to mesh with the fifth gear, and the fifth gear is configured to mesh with the fixed rack gear.
Further, the type and shape of the gears are different from those of the sixth embodiment. That is, the first gear 3206 of this example is a helical gear. The small gear 3228b of the fifth gear meshing with this is a worm gear. Further, the large gear 3228a of the fifth gear is the same as the fourth gear of the sixth embodiment in that it is a spur gear. However, since the rotation axes of the Hasuba gear and the worm gear are orthogonal to each other, The large gear sharing the rotation axis is arranged horizontally. Therefore, the fixed rack gear that meshes with this is also arranged so that the teeth are facing upward in the sixth embodiment, whereas in this embodiment, the teeth are arranged sideways (inward).

(Relationship between components (1) meshing relationship)
FIG. 33 is a diagram for explaining the meshing relationship of these gears. First, the first gear 3306 meshes with the small gear 3328b of the fifth gear 3328. Also, the second large gear 3328a sharing the rotation axis with the small gear meshes with the fixed rack gear 3310.

(Relationship between components (2) Rotational transmission relationship)
Returning to FIG. 32, the rotation transmission relationship between these components will be described next. As a premise thereof, although omitted in FIG. 33, as shown in FIG. 32, the fifth gear 3228 is rotatably attached to one slide plate 3208 by a pin 3214 and an E-ring (not shown in the figure). Yes. FIG. 34 shows an example of the shape of the slide plate 3408, and shows an example similar to that shown in FIG. FIG. 34A shows the positional relationship between the slide plate, the pin, and the E ring when the fifth gear (not shown) is attached to the slide plate 3408 with the pin 3414 and the E ring 3415. FIG. 34 (b) shows these separated for reference. Holes 3408a and 3408b formed in the upper and lower horizontal plate-like portions of the slide plate are holes for passing pins. An example of the shape of the fifth gear will be described later. From the above configuration, the fifth gear suitable for the configuration of the slide plate of the present example has a through hole for allowing the pin to pass through the center of the gear. .
The slide plate is movably attached to a chassis side plate provided on the side surface of the first housing. Since the attachment method is the same as that of the sixth embodiment, description thereof is omitted. 3421a to 3421c are slide shafts.

  Therefore, the rotational transmission relationship between these components is as follows. Here, unlike the sixth embodiment, the description will be made in the order in which the rotation is sequentially transmitted from the fifth gear to the first gear and the display rotation shaft. In particular, when the rotation cannot be transmitted from the first gear to the fifth gear due to the characteristics of the worm mechanism (when the self-lock is applied), this transmission order is essential. The configuration of the present embodiment is suitable for one that performs an opening / closing operation mainly by driving a motor. This is because, when driven by a motor, it is practical to dispose the motor on the second housing side slide portion. In the following, description will be made with the motor driving in mind. However, if the torsion angle of the worm gear is large, self-locking is not applied and rotation may be transmitted from the first gear to the fifth gear. This does not exclude the case where is sequentially transmitted to the first and fifth gears. That is, the expression “the fifth gear is a gear to which the rotation of the display rotation shaft is transmitted” according to claim 9 is used in a sense including transmission by both of the above transmission orders.

  In FIG. 33, when the fifth gear large gear 3328a rotates in the direction of arrow D (horizontal counterclockwise direction) by driving a motor (not shown), the fifth gear small gear 3328b sharing the rotation axis with this large gear. Also rotate in the D direction. Further, since the small gear is a weam gear, and the first gear 3306 meshing with it is a helical gear, when the small gear rotates in the D direction, the first gear is in the direction of the arrow C (the direction perpendicular to the D direction). And rotate clockwise). The display rotation shaft 3304 having the first gear at the tip rotates in the direction of arrow A (the same clockwise direction as the C direction). On the other hand, since the large gear of the fifth gear meshes with the fixed rack gear 3310, the large gear moves horizontally in the arrow B direction. Since the fifth gear is attached to the slide plate as described above, the slide plate horizontally moves in the B direction as the fifth gear moves horizontally (more specifically, the slide plate is moved to the first housing). It is guided in the guide groove of the chassis side plate provided on the side of the body and moves horizontally in the direction of arrow B). As a result, the first gear meshing with the fifth gear also moves horizontally in the B direction, and the display rotation shaft having the first gear also moves horizontally in the B direction.

  Next, in this embodiment, a specific configuration for realizing an operation in which the horizontal movement of the rotary shaft is completed at the same time that the rotary shaft rotates 180 degrees in order to reverse the second casing will be described. . First, the relationship of the rotation angle between the first gear and the fifth gear will be described. FIG. 35 is a diagram for explaining an example of the relationship of the rotation angle between the first gear and the fifth gear, and is an enlarged view of the portion of FIG. In general, in meshing of a worm gear (worm, screw gear) and a helical gear (worm wheel), when the worm gear rotates once, the helical gear advances (rotates) by one tooth. In the example of this figure, the tooth at the position of 3506a of the first gear comes to the position of 3506b when the small gear of the fifth gear makes one rotation. Similarly, when the small gear of the fifth gear makes one more rotation, the tooth at the position of 3506b of the first gear comes to the position of 3506c. In general, the number of rotations of the meshing gears is inversely proportional to the number of teeth. In this example, the number of teeth of the first gear 3506 is 16 and the number of teeth of the small gear of the fifth gear is 4 (note that the figure is only for explaining the concept, The number of teeth shown does not necessarily match the number of teeth in this example, and so on. Therefore, since the gear ratio of the small gear of the first gear and the fifth gear is 4 to 1, the rotational speed of the small gear of the fifth gear is four times that of the first gear. For this reason, in order to rotate the display rotation shaft 180 degrees in order to invert the second casing, that is, in order to rotate the first gear 180 degrees, the small gear of the fifth gear is 720 degrees ( = 180 × 4) It is necessary to rotate. This means that the large gear of the fifth gear sharing the rotation axis with this small gear needs to rotate 720 degrees. Speaking of this in the order of transmission, when the fifth gear large gear rotates 720 degrees by driving the motor, the fifth gear small gear also rotates 720 degrees, and the meshed first gear rotates 180 degrees. Therefore, the display rotation axis also rotates 180 degrees.

  Next, the relationship of the rotation angle between the large gear of the fifth gear and the fixed rack gear will be described. In this case, since the fixed rack gear is fixed and does not move, the large gear of the fifth gear moves on the track of the fixed rack gear from the rearmost end in the depth direction to the frontmost end while rotating at a predetermined rotational speed. This predetermined number of rotations is also determined by the ratio of the number of teeth of both. The fifth gear and the number of teeth in this example are 32, and the number of teeth of the fixed rack gear is 64. Then, the large gear of the fifth gear rotates twice (= 64/32), that is, 720 degrees while moving from end to end on the track of the fixed rack gear. As described above, the display rotation shaft rotates 180 degrees while the fifth gear of the fifth gear rotates 720 degrees. During this time, the large gear moves from end to end on the track of the fixed rack gear. Thus, it is possible to realize a configuration in which the horizontal movement is completed simultaneously with the completion of the front-back inversion.

(Description of each component (1) First gear)
FIG. 36 is an example of the shape of the first gear and is the same as that shown in FIG. FIG. 36A is a view from the front, and FIG. 36B is a view from the side. As shown in the figure, the first gear 3606 of this example is a helical gear (worm wheel). This is for engaging with the fifth gear which is a worm gear. In addition, since the gear teeth of the helical gear are formed obliquely, the contact area between the teeth is large compared to the gear width and a large force can be transmitted. Further, since two or more teeth are always meshed with the worm gear and rotated, there is a feature that noise and vibration are small. Further, it has a feature that the strength of the gear is increased as compared with the spur gear. Therefore, this feature can be utilized for the purpose of the configuration described later.

(Description of each component (2) Fifth gear)
FIG. 37 shows an example of the shape of the fifth gear, which is the same as that shown in FIG. FIG. 37A is a view seen from the front, FIG. 37B is a view seen from a plane (upper surface), and FIG. 37C is a view seen from a bottom surface (lower surface). As shown in this figure, the fifth gear 3728 of this example has a small gear 3728b and a large gear 3728a, the small gear is a worm gear (worm, screw gear), and the large gear is a spur gear. This is because the small gear meshes with the first gear, which is a helical gear, and the large gear meshes with the fixed rack gear. In addition, the worm gear has a feature that a large speed reduction effect can be obtained because the helical gear meshing with the worm gear is rotated (rotated) by one rotation. Therefore, this feature can be utilized for the purpose of the configuration described later.

(Purpose of configuration)
As described above, the first gear that is a helical gear and the fifth gear that is a worm gear are sequentially meshed with each other. The purpose is to obtain. For example, when the apparatus of the present embodiment is driven by a motor, it is practical to provide a drive unit on the second housing side slide portion as described above, and therefore the rotation by the motor drive is changed from the fifth gear to the second gear. The transmission order is such that it is transmitted to the display rotation shaft via a single gear. Therefore, by adopting the configuration as in the present embodiment, when the rotation speed of the fifth gear is transmitted to the first gear, the speed is reduced, thereby reducing the load and obtaining a large torque although the rotation efficiency is reduced. it can. In the above example, the case where the gear ratio of the small gear of the first gear and the fifth gear is 4 to 1 is explained, but if this gear ratio is further increased, a large torque can be obtained with a smaller load. it can. In addition, since such an operation can be achieved with one-stage deceleration, the mechanism can be made compact, and an effect excellent in applicability to a small electronic information display device such as a portable terminal can be exhibited. It becomes. If the self-locking is not applied, the configuration of the present embodiment can be used for a device of a type in which the second casing is turned upside down by a manual opening / closing operation. In this case, rotation is transmitted from the first gear to the fifth gear, and a large load is applied. However, the strength can be increased by using the helical gear as the first gear. So there is no problem.
Secondly, this configuration aims to provide a device with less noise and vibration. In other words, the meshing of the helical gear and the worm gear has a feature that noise and vibration can be reduced because line contact is made as described above and relative slip is large. Thus, by adopting such a configuration, it is possible to provide an apparatus with low noise and vibration that is desirable for an electronic information display apparatus.

<Effect>
According to the present embodiment, a large torque can be obtained with a smaller load, and an electronic information display device having a compact mechanism can be provided. In addition, it is possible to provide a device with low noise and vibration.

<Overview>
The electronic information display apparatus of the present embodiment is basically the same as the apparatus of the seventh embodiment, but the first gear is formed as a separate part from the display rotation shaft and is integrated with the display rotation shaft. It is characterized by being fitted in a rotatable manner.

  <Configuration>

(Configuration overview)
FIG. 38 is a diagram illustrating an example of the shape of the display rotation shaft and the first gear of the electronic information display device of the present embodiment, and the same shape as that described with reference to FIG. A first gear 3806 is formed as a separate part from the display rotation shaft 3804 and is integrally fitted to the display rotation shaft so as to be rotatable. Among these, Fig.38 (a) shows the state in which both were fitted, and (b) shows the state in which both were isolate | separated. The fitting method is not particularly limited as long as the display rotation shaft and the first gear can rotate as a unit during operation.

It is characterized in that it further has a holder portion for preventing the wire bundle from coming into contact with the gear.

<Configuration>
(Outline of configuration, purpose of configuration)
FIG. 39 shows a part of the external appearance of the electronic information display apparatus of this embodiment, which has a bundle of wires 3916 and a holder 3929, with the top and side covers and the like removed so that they can be seen (note that In order to make the shape of the holder portion easier to see, the slide plate and the second to fourth gears are also omitted). The wire bundle is for exchanging electrical signals with the first housing side. Further, when the apparatus is opened and closed by driving a motor, it may be used for exchanging electrical signals between the inside of the second casing and the motor. In the example of this figure, the wire bundle passes from the first housing side to the upper side of the display rotation shaft 3904 through the insertion hole 3923 provided in the first gear 3906. The holder portion 3929 is for preventing the wire bundle from contacting the gear. This is because the electronic information display device is preferably small, so the wire bundle needs to pass through the gap between the very narrow first gear and the gear (for example, the second gear) constituting the second housing side slide part. By providing such a holder portion, it is an object to prevent the wire bundle from coming into contact with the gears to cause a disconnection or obstructing the opening operation of the entire apparatus.

FIG. 40 shows an example of the shape of the wire bundle 4016. The specific shape and material are appropriate design matters for those skilled in the art.

(Description of each component (1) Holder part)
FIG. 41 shows an example of the shape of the holder part. As shown to (a), in this example, a holder part is comprised so that the wire bundle 4116 may be hold | maintained combining the upper side 4129a and the lower side 4129b. (B) shows the upper part of the holder part, and (c) shows the lower part of the holder part. In (a), the line bundle is held substantially in the state (orientation) shown in (d).

State seen from the above). FIG. 43 also shows the function of the holder part for preventing the wire bundle from coming into contact with the gear, in order to easily understand the function of the holder (FIG. 43 (b)) and without the gear (FIG. 43 (a)). )). With such a configuration of the holder portion, it is possible to prevent the wire bundle from coming into contact with the gear.

<Effect>
According to the present embodiment, it is possible to prevent the wire bundle from coming into contact with the gears to cause disconnection or to hinder the opening operation of the entire apparatus.

<Overview>
The electronic information display apparatus of this embodiment is basically the same as any one of the embodiments 6 to 9, except that at least one of the first gear to the fourth gear deviates from the normal position. It is characterized in that it further has a cover portion for preventing.

<Configuration>
(Outline of configuration, purpose of configuration)
FIG. 44 is obtained by adding a cover portion 4430 to FIG. However, the wire bundle and the holder part may not be provided. The cover portion is for preventing at least one of the first gear to the fourth gear from deviating from the normal position. Since the first gear to the fourth gear are sequentially meshed with each other to form a gear train for performing a series of operations, if any one of these gears falls off or shifts during operation, The operation cannot be performed smoothly. Therefore, such a configuration is intended to smoothly perform the operation by preventing the gear from deviating during the operation.

(Description of components)
FIG. 45 shows an example of the shape of the cover portion 4530. Of these, FIG. 45 (a) is viewed from the substantially same direction as FIG. 44, and (b) is viewed from the substantially back side of (a). The specific shape and material of the cover part are appropriate design matters for those skilled in the art.

<Effect>
According to the present embodiment, it is possible to prevent the gear from deviating during operation and to perform the operation smoothly.

<Overview>
The electronic information display apparatus according to the present embodiment is basically the same as the apparatus according to the ninth or tenth embodiment, but the second casing-side slide portion further includes a relay board that relays the wire bundle, and this is provided on the second casing side. It is characterized in that it is arranged on the slide forward front of the slide part or the slide backward front of the slide part.

<Configuration>
(Outline of configuration, purpose of configuration)
FIG. 46 is obtained by adding a relay board 4617 to FIG. The relay board is for relaying the wire bundle 4616. The relay board according to the present embodiment is configured to be arranged on the slide front side of the second casing side slide part or the slide back side of the slide part. “Sliding forward front” refers to the front in the forward direction when the second housing side sliding portion moves horizontally according to the opening / closing operation of the second casing, and “sliding forward front” refers to the second This refers to the front in the backward direction (the back in the forward direction) when the housing-side slide portion moves horizontally according to the opening / closing operation of the second housing.

  In the example of FIG. 46, the constituent elements of the second housing side slide part in which the slide plate 4608, the holder part 4629, and the cover part 4630 are added to the second, third, and fourth gears not shown are for the opening operation. When moving horizontally in the direction of arrow B as a unit, the front in the B direction becomes the forward front, and the surface in the B ′ direction opposite to this is the rear in the forward direction, that is, the front in the backward direction. . Therefore, since the relay base 4617 shown in this figure is arranged in front of the B ′ direction, that is, in front of the second casing side slide part in the retreat direction, it is arranged in the “slide retreat front”. Become. On the other hand, when the second housing side slide part moves horizontally in the direction of the arrow B ′ for the closing operation, the front in the B ′ direction becomes the front of the forward movement, so that the front of the B ′ direction is arranged in this figure. The relay board is literally arranged “in front of the slide”. In other words, because the forward movement direction of the second housing side slide portion is different between the opening operation and the closing operation, only two ways of saying “sliding forward front or sliding backward front” are used, and the arrangement position changes. Not to do. In short, the relay board is arranged on the surface facing the B ′ direction of the second housing side slide portion. The reason for the above configuration is to dispose the relay board on such a surface so that it is not necessary to increase the size of the apparatus.

(Description of components)
FIG. 47 shows an example of the shape of the relay board 4717. FIG. 48 shows a state in which the relay board 4817 is connected to the wire bundle 4816. Of these, FIG. 48 (a) is viewed from substantially the same direction as FIG. 46, and (b) is viewed from the back side of the relay board. The specific shape of the relay substrate and the specific connection method with the wire bundle are appropriate design matters for those skilled in the art.

<Effect>
According to the present embodiment, by arranging the relay board on the slide forward front of the second housing side slide part or the slide reverse front of the slide part, it is not necessary to increase the size of the apparatus, and it is possible to provide a compact apparatus. Become.

The foldable flat cable further includes a foldable flat cable, and the foldable flat cable is characterized in that it is located on the bottom surface of the second housing side slide plate.

<Configuration>
(Outline of configuration, purpose of configuration)
FIG. 49 is obtained by adding a foldable flat cable 4918 and a flat cable fixing bracket 4918a to FIG. The foldable flat cable is for exchanging electrical signals between the relay board and the first housing side, and can be folded along with the movement of the slide plate. The flat cable fixing bracket is for fixing the foldable flat cable to the second housing side slide portion. However, since the foldable flat cable is connected to the relay board 4917 as described later, the flat cable is fixed. There is no need for a fixing bracket, but it is desirable that the fixing bracket be fixed in order to smoothly fold the flat cable accompanying the movement of the slide plate. FIG. 50 shows an example of the shape of the flat cable fixing bracket for reference. The reason why the folding flat cable is configured to be positioned on the bottom surface of the second housing side slide plate is to prevent an increase in apparatus size.
