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. It is an object of the present invention to provide a connection structure that can be applied to an electronic information display device and can be reversed and reversed by a simple operation. Also, an electronic information display device comprising such a connection structure, the electronic information display device configured such that each side of the casing does not protrude from the overlapping surface of the second casing when re-superposed.

Move horizontally to the middle to the opposite side of one housing (necessarily does not need to be half the length of the side of the first housing), then the rest (from the middle to the first A structure that performs horizontal movement (to the opposite side of the housing) (therefore, the action is two actions of “turn and slide”), or a connection structure that can realize such a front-to-back inversion operation, or this is applied.

Applicable.

<Configuration>
(Definition of features and terms of composition)
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 first casing and the second casing in a state in which the front and back of the second casing are reversed from the initial overlapping state. Are configured so as to be linked with the operation of partially overlapping each other. 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.

1 and 2 are conceptual diagrams illustrating an example of a configuration of a connection structure according to the present embodiment. Among these, FIG. 1 shows an operation in time series until the first housing and the second housing are partially overlapped by the front / back reversing operation of the second housing. First, (a) shows an example of the state of the connection structure when not in 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.
Next, when using this connection structure, as shown in FIGS. 1B to 1H sequentially, first, the second casing 0102 is rotated in the reverse direction so that the front and the back are reversed. Then, partially overlap each other so that the use surface of the second casing 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. The connection part shown in this figure has a pivot support structure, and the second housing rotates in the direction of arrow A shown in FIG. 1C with the connection part as the center of rotation, and the connection part is It moves horizontally in the direction of arrow B throughout the entire period, and at the same time as the second casing rotates 180 degrees, the front and back inversion is completed and the use surface 0102a appears on the surface. At this time, the second casing and the first casing are partially overlapped as shown in FIG. That is, the second casing and the first casing are not exactly overlapped by this interlocking operation.
Therefore, in order to change the second housing from this state to the state where the second housing is exactly overlapped on the first housing, as shown in FIG. 2 (a) to (d) in time series, The side 0202a (indicated by a thick solid line) that appears on the opposite side of the first casing among the second casings on the first casing 0201 faces the first casing 0201. It is horizontally moved in the direction of arrow B to a position (indicated by a broken line) overlapping with the side 0201c (indicated by a thick solid line). By this operation, the second casing is exactly overlapped with the first casing and is in a state of use. That is, FIG. 2D shows a state in use.

(Synchronization between rotation and partial overlay)
In addition, the connection structure of the present embodiment realizes the “partial overlap” state when performing the above-described rotation operation and partial overlap operation in conjunction with each other. The connecting portion with the second casing is configured to horizontally move to the center of the overlapping surface of the first casing in accordance with the rotation operation. FIG. 1 also shows such an example. As shown in FIG. 1H, as a result of the above-described interlocking operation, the connecting portion 0104 between the first casing 0101 and the second casing 0102 is the first portion. It will be in the state horizontally moved to the center part of the overlapping surface 0101a of the housing.
The “center portion” refers to a central portion (a region surrounded by a dashed circle 0101b) of the overlapping surface of the first casing. A feature of the present invention is that the two casings are combined with a 180-degree rotation operation on the first casing and a horizontal movement operation so that the two casings are exactly overlapped, and in the middle of the entire operation. It does not strictly ask how the two casings overlap at the time of completing the rotation operation of the 180-degree rotation operation that is the stage. Therefore, it is sufficient that the “center of the plane” is within the approximate range as described above, and it is not necessary to be in an exact position.
Moreover, the connection site | part of the connection structure of a present Example is the pivot connection structure which rotates a 2nd housing | casing centering on one side of a 2nd housing | casing, for example. In that case, the axis that forms the pivot connection structure of the connection structure of the present embodiment is, for example, the opposite side of the first case that faces this side from one side of the first case according to the rotation operation. It is configured to move to the middle to the side.
FIG. 3 is a conceptual diagram for explaining the structure, and is a perspective view showing the same structure as that shown in FIG. In FIG. 3A, reference numeral 0304 denotes a shaft that forms a shaft connection structure. Further, “one side of the second housing” is indicated by 0302b. “One side of the first housing” refers to either one of the two sides 0301a and 0301b indicated by bold lines (solid lines or broken lines) in FIG. 3, and “the opposite side of the first housing that faces this side”. Means the remaining of the two sides. In the following description, “one side of the first housing” is 0301a, and “opposite side of the first housing facing this side” is 0301b. In this case, the “one side of the first casing” refers to a range indicated generally by 0301c, that is, a range that generally overlaps above the side 0301a in the second casing. The “opposite side of the first casing facing this side” refers to a range indicated generally by 0301d, that is, a range that generally overlaps above the side 0301b in the second casing.

  “Intermediate from one side of the first housing to the opposite side of the first housing facing this side” refers to a range located between the range indicated by 0301c and the range indicated by 0301d. Typically, the range generally indicated by 0301e is shown. This also does not need to be an exact position, and it is sufficient if it is within this range. This is also due to the same reason as described above. In the example of this figure, the shaft 0304 forming the shaft support connection structure moves horizontally in the direction of arrow B from the position 0301c to the position 0301e in accordance with the rotation operation. “According to the rotation operation” means that the second casing rotates around the connecting portion as the center of rotation, and the connecting portion moves horizontally throughout the rotation, and the second casing However, it means that the use surface appears on the surface after turning 180 degrees at the same time as the rotation is completed. As a result, when this connection structure is used, as shown in FIGS. 3B and 3C in sequence, the second housing 0302 rotates the shaft that forms the shaft connection structure. While rotating in the direction of arrow A as the center, the connection part moves horizontally in the direction of arrow B toward the position indicated by 0301e throughout the rotation, and the process ends as shown in FIG. 3 (d). In the state of time, the state where the shaft 0304 forming the shaft support connection structure has moved to the position 0301e, that is, the state where the second housing 0302 is partially overlapped with the first housing 0301 with the front and back reversed. Become. 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 appearance and shape of a shaft shown in FIG. is there. 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.

  Next, in order to change from the state shown in FIG. 3D to the state in use, as shown in FIG. 2, the second housing is exactly overlapped with the first housing (the position shown by the broken line). ) Is moved horizontally in the direction of arrow B. For this movement, for example, the connecting structure has a wheel that travels using an arc spring fixed to the second casing as a rail. It is configured to be pressed by the spring until it exceeds the bow top of the bow spring which is bent as the vehicle travels, and to be released from the pressure of the bow spring after the bow top is passed. Details of this configuration example will be described later.

(Other configuration examples)
In the above description, the case where the first casing and the second casing have the same bottom area (therefore, the case where the second casing exactly overlaps the first casing) is taken into consideration. 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. 4 is a perspective view showing such an example (FIG. 4 (a) shows a non-use state and (b) 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. 5 is a perspective view showing such an example (FIG. 5A shows a non-use state and FIG. 5B 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.

  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. 6 is an example of an external appearance of an electronic information display device 0600 to which such a connection structure is applied, and shows an external appearance when not in use (for convenience of explanation, the side cover is removed from the external cover and the internal structure is removed). Part of the mechanism is shown.) In addition, although not appearing in the drawing, the shaft (but part of which is visible as 0604) that forms the pivot coupling structure that forms the coupling portion is on one side that appears on the right side of the second housing 0602. It is embedded inside the housing, and the second housing is structured to move horizontally in the direction of arrow B while rotating in the direction of arrow A.

<Effect>
In accordance with the invention of this embodiment, an electronic information display device having an opening / closing 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 Therefore, it is possible to provide a connection structure that can be applied to the above and that can be reversed and reversed by only a simple operation.
In particular, in order to realize the operation of reversing the front and back so that the second casing does not protrude from the overlapped surface in this way, a simple structure is realized. To provide a connection structure that can realize such a front-to-back reversal operation by horizontally moving to the middle of the opposite side of the first housing in conjunction with the rotation of the first case, and then horizontally moving the remaining part. Is possible.

<Overview>
The connection structure of the present embodiment is basically the same as the connection structure of the first embodiment in which the connection portion is a pivot connection structure that rotates the second housing around one side of the second housing. . However, the shaft of the second housing is configured by a slide shaft support structure so as to slide relative to the inside of the second housing, and this slide shaft support connection structure is The arcuate spring fixed to the second casing runs as a rail and is pressed by the spring until it exceeds the bow apex of the arcuate spring that is bent along with the run, and after the bow apex is exceeded, Characterized by having a wheel that is released from the pressure of the arcuate spring.

(Definition of features and terms of composition)
FIG. 7 shows the connection structure of the present embodiment in the same example of the electronic information display apparatus as shown in FIG. 6, and in order to show the internal structure of the second casing, It shows the state where the top cover is removed in addition to the side cover of the outer cover of the body. Here, using this figure, the shaft of the second housing is configured by a slide shaft support structure so as to slide relative to the inside of the second housing, and FIG. As an example of a specific configuration for performing horizontal movement for changing from the state shown in d) to the state in use, a wheel that travels using an arcuate spring with a connecting structure fixed to the second housing as a rail is provided. It is configured to be pressed by this spring until it exceeds the bow top of the bow spring that is bent as the wheel runs, and to be released from the pressure of the bow spring after it has passed the bow top. An example will be described.
As shown in the drawing, the second casing is composed of a chassis main body portion 0705 including a chassis 0703 and a portion 0705a other than the chassis, a slide fitting 0724 located on the lower side of the chassis, and a display rotation attached to both sides thereof. And a slide shaft support structure 0725 (shown by hatching) including the shaft 0704. The “slide shaft support structure” in this embodiment is a shaft (in this example, including a display rotation shaft and a slide fitting added thereto) that forms a shaft support structure, and is provided inside the second casing. A structure that is configured to relatively slide. This slide fitting has wheels (rollers) 0726a-c attached by E-rings or the like through guide grooves 0727 provided in the chassis, and the slide fittings are moved by the horizontal movement in the guide grooves. It has a structure that can slide in the main body part of the second housing (under the chassis). At that time, an arcuate spring 0714 is attached to the chassis in such a manner that it is fixed by an arcuate spring fixing bracket 0715, and one of the wheels 0726a moves along the guide groove while repelling the urging force of the arcuate spring. Will move. In order to perform a stable sliding operation, as shown in this figure, it is preferable that a mechanism similar to that on the arcuate spring 0714b or the like is provided on the opposite side surface of the apparatus. In addition, the number and position of the guide grooves in this figure, and the number and position of the wheels are only examples, and if the slide fitting is configured to be movable in the housing body with the above configuration, Other numbers and positions may be used. This figure shows the state when not in use, and the components of the second casing are the top cover (not shown), chassis, slide bracket, and chassis main body other than the chassis from the top. It will be in the state arrange | positioned in order of the part (The chassis main body part other than a chassis is united). Further, at the bottom of the casing main body portion, the display surface is disposed facing downward so as to face the first casing.
FIG. 8A shows only the main body portion 0805 and the slide shaft support structure 0825 (shown by hatching) of FIG. 7, and FIG. 9 shows the chassis 0903 among them. FIG. 10 shows a slide shaft support structure 1025 made up of a slide fitting 1024 and a display rotation shaft 1004. These figures are examples of an electronic information display device having a display surface. As shown in FIG. 8B, which is a view of FIG. 8A viewed from the back side, the main body portion of the second housing is shown. The display surface 0802a is positioned on the back side.

(Specific configuration for sliding shaft support structure to slide inside the chassis body)
Next, a specific configuration for the slide shaft support structure to slide in the housing body (lower side of the chassis) will be described.
FIG. 11 schematically shows the housing body and the slide support structure in order to explain such a configuration. Among these, (a) shows a state in which the second casing is reversed and partially overlapped on the first casing in order to change from the non-use state shown in FIG. For convenience of comparison with FIG. 8 and the like, the first housing 1101 is shown on the upper side and the second housing 1102 is shown on the lower side (in order to visually supplement this state, (a) The figure shows a state in which the apparatus is installed on the desk 1128. That is, this figure shows the actual arrangement upside down, while the illustration of the desk is omitted in (b) to (d). It is the same state as a). Accordingly, the display surface 1102a is located on the lower side in this figure as well, and other than the upper surface cover (not shown), the chassis 1103, the slide shaft support structure 1125 (shown by the right-down oblique line), and the chassis of the second casing. The portion 1105a is arranged in this order from the top. Also, (b) to (d) show the time series from the state of (a) until the second casing is horizontally moved to the state of use, and (b) and (c). Is a state in the middle of horizontal movement, and (d) is a state in use when the horizontal movement is completed.
In order to perform horizontal movement from the state of FIG. 11A, the second housing is pushed in the direction of arrow B. This operation is performed, for example, when a person pushes it in by hand. Then, as described above, in the second casing, the slide pivot support structure is configured to be slidable within the casing main body. It moves horizontally in the direction opposite to the direction. However, actually, as shown in (b), the slide shaft support structure itself does not move, and the case body portion that is directly pressed moves in the pressed direction, so that the slide shaft support structure moves in the opposite direction. Relative movement is realized. In this way, the structure in which the slide support structure does not move in the positional relationship with the first housing fixed to the table, for example, as shown in the example of FIG. 10, the slide support structure 1025 is a slide fitting 1024. And a shaft forming a shaft connection structure (more specifically, a display rotation shaft of the electronic information display device in this figure) 1004 are integrally configured. As will be described later, the shaft forming the shaft connection structure is a first shaft. This can be realized by using a frictional force generated by engaging the first housing side slide portion and the second housing side slide portion provided on one housing side.
Furthermore, (d) further pushes the portion 1105a other than the slide support structure in the second casing in the direction of arrow B until the second casing is exactly overlapped on the first casing. It shows a state of horizontal movement, that is, a state in use. In order to make the first, second, and second housings exactly overlap in this way, the second housing has a relative sliding movement range within the second housing of the slide support structure. The slide stopper is in a state where the first housing and the second housing are completely overlapped when sliding from the partially overlapped state to the restriction position by the stopper. You may comprise so that it may be arrange | positioned.

(Specific configuration of slide mechanism using bow spring)
Next, a specific configuration of the slide mechanism using the bow spring for the horizontal movement will be described.
FIG. 12 schematically shows a plan view of a portion surrounded by a broken-line ellipse 0805a in the chassis and the slide fitting below the chassis shown in FIG. 8, and the second housing is the first case. From the state where the front and back are reversed and partially overlapped on the housing, the slide housing structure of the second housing is relatively pushed into the other portion of the second housing and the second housing This shows the state of horizontal movement to a position where the first casing and the first casing exactly overlap each other. In the figure, (a) to (d) correspond to (a) to (d) in FIG. 11, respectively. In the figure, reference numeral 1215 denotes an arcuate spring fixing bracket, 1214 denotes an arcuate spring, 1227 denotes a guide groove, and 1226a denotes a wheel attached to the slide fitting.
The state shown in FIG. 5 (a), that is, the second housing is reversed upside down on the first housing and partially overlapped (this is because the display surface of the second housing is not used). The wheel is positioned at the right end of the guide groove by being pushed by the urging force that tries to spread outside the arcuate spring. ing. Therefore, as shown in (b), the wheel is relatively moved by pushing it in the direction of the arrow B ′ along the guide groove (as described above, the wheel does not actually move and the chassis including the arched spring is When the slide shaft support structure moves in the direction opposite to the arrow B ′ direction, the slide shaft support structure travels in the guide groove with an arcuate spring fixed to the second housing as a rail. In this case, the spring is pushed against this force while it is pressed by the spring until it exceeds the arch top of the bow spring (the part indicated by the arrow with 1214a in (a)) that is bent along with this running. It is necessary to push in with a certain amount of force. However, as shown in (c), after the wheel has passed over the top of the bow, the wheel is positioned on the left side of the top of the bow. The wheel reaches the end on the opposite side of the guide groove in a form pressed by the leftward biasing force. For this reason, the person who pushes in the second housing needs to push in with a certain amount of force at the beginning of the push (specifically, until the wheel crosses the top of the bow). After that, the second casing can be easily pushed to the point where the second casing is exactly overlapped with the first casing.

In accordance with the invention of this embodiment, an electronic information display device having an opening / closing 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 Therefore, it is possible to provide a connection structure that can be applied to the above and that can be reversed and reversed by only a simple operation.
In particular, in order to realize the operation of reversing the front and back so that the second casing does not protrude from the overlapped surface in this way, a simple structure is realized. To provide a connection structure that can realize such a front-to-back reversal operation by horizontally moving to the middle of the opposite side of the first housing in conjunction with the rotation of the first case, and then horizontally moving the remaining part.

<Configuration>
(Definition of features and terms of composition)
FIG. 13 is a diagram showing an example of the appearance of an electronic information display device similar to that shown in FIG. 6, in which the second housing 1302 has the display surface 1302a. 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. 6 so that a display surface may appear in a 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. The electronic information display device shown in the figure has a pivot connection structure in which a connection portion (not shown in the figure) rotates the second casing around the side 1302b of the second casing. In this example, a connecting structure is used in which the shaft forming the structure moves from one side 1301a of the first casing 1301 to the middle of the first casing facing the side 1301b in accordance with the rotation operation. is there. Therefore, the “distance corresponding to the rotation of about 135 degrees” shown in this figure is a distance of about 3/4 of about 1/2 of the length L of the side of the first housing, that is, about 3/8. It turns out that.

  In this case, when the second casing is further rotated about 45 degrees in the direction of the arrow A ′ thereafter, the front / back inversion is completed, and the second casing partially overlaps the first casing with the display surface facing the front side. It becomes a state. “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 embodiment 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 third embodiment, but a set of slide portions (first housing side) that moves from one side of one housing to the middle from the opposite side. The display rotation shaft, the second housing side sliding portion, and the first housing side sliding portion each have a gear, and the rotation is transmitted by these. It is characterized in that the rotation and horizontal movement of the second casing is realized.

<Configuration>
(Configuration features)
FIG. 14 is the same apparatus as the electronic information display apparatus shown in FIG. 7, showing an example of the appearance of components related to the rotation of the second casing and the horizontal movement in conjunction with the rotation of the electronic information display apparatus of this embodiment. FIG. 8 is a view in which the chassis and the slide fitting of the second casing are further removed from the state shown in FIG. 7 so that the mechanism for internal rotation and horizontal movement can be seen. These components are roughly classified into a display rotation shaft 1404, a second housing side sliding portion, and a first housing side sliding portion. The display rotation shaft 1404 has a first gear 1406 at its tip. The second housing side slide portion has a second gear 1407 and a slide plate 1408. The first housing side slide portion has a fixed rack gear 1410 and a chassis side plate 1409. Further, as is apparent from a comparison of this figure with FIGS. 6 and 7, the display rotation axis is arranged 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. The second gear is for transmitting the rotation of the display rotating shaft and the first gear attached to the tip of the display rotating shaft to the fixed rack gear of the first housing side slide portion. The fixed rack gear is fixed to the first housing body and has a structure that does not move. In FIG. 14, reference numeral 1412 denotes a bearing portion. The bearing portion, the slide plate 1408, and the main body chassis side plate 1409 of the first housing will be described later.
FIG. 14 shows an example in which the display rotation shaft, the first housing side slide portion, and the second housing side slide portion are provided on both side surfaces of the apparatus. The side cover on the side was also removed). From the viewpoint of smooth sliding operation, it is desirable that the slide portions are provided on both side surfaces as described above. However, this is not essential, and the slide portions are provided only on one side surface. May be.

(Relationship between components (1) meshing relationship)
FIG. 15 is a diagram for explaining the meshing relationship between these gears. In FIG. 14, only the display rotating shaft, the first gear, the second gear, and the fixed rack gear are taken out and shown together with their relative positional relationships. It is a figure.
As shown in (a), first, the first gear 1506 meshes with a small gear (not shown) of the second gear 1507. Also, the second large gear 1507 a sharing the rotation axis with the small gear meshes with the fixed rack gear 1510. (B) is a figure for demonstrating the meshing relationship of each of these gears similarly, Comprising: It is the figure seen from the angle different from (a) (generally right and diagonally downward). In this figure, the meshing relationship between the first gear 1506 and the small gear 1507b of the second gear 1507, not shown in FIG.

(Relationship between components (2) Rotational transmission relationship)
Next, the rotation transmission relationship between these components will be described. The rotational transmission relationship between these components is as follows. In this example, the rotation is sequentially transmitted from the display rotation shaft to the first gear and the second gear, but this is because the configuration of the present embodiment mainly opens the second housing manually. This is because it is suitable for the operation of making the state in use. However, the configuration of the present embodiment does not exclude the case where, for example, the rotation of the second gear is sequentially transmitted to the first gear and the display rotation shaft by driving a motor provided in the second housing side slide portion or the like. .
Therefore, as shown in FIG. 15A, when the display rotating shaft 1504 rotates in the direction of arrow A, the first gear 1506 at the tip also rotates in the C direction (the same clockwise direction as the A direction) and meshes therewith. A small gear (not shown in the figure) of the second gear 1507 rotates in the direction of arrow D (counterclockwise direction). Then, the large gear 1507a of the second gear sharing the rotation shaft with the small gear also rotates in the D direction. Since the large gear meshes with the fixed rack gear 1510, the large gear moves horizontally on the fixed rack gear in the direction of arrow B.
Next, the configuration for horizontally moving the entire second casing in the same direction as the large gear of the second gear horizontally moves in the direction of arrow B on the fixed rack gear will be described. FIG. 16 shows the second gear 1407, the slide plate 1408, and the main body chassis side plate 1409 extracted from FIG. As shown in this figure, the second gear 1607 is rotatably fitted to a gear shaft 1613 provided on the slide plate 1608 with screws 1613a, nuts 1613b, etc. ( 2 gears, slide plate, etc. are shown separated from each other).
FIG. 17 shows the same shape as that shown in FIG. 16 as an example of the shape of the slide plate. As shown in (a), a gear shaft 1713 for rotatably fitting a second gear (not shown) is planted on the slide plate 1708. Further, (b) shows the slide plate of (a) from a different angle with the back side visible. As shown in (b), slide shafts 1721a-c are inserted and fitted at three positions on the back surface of the slide plate 1708, and slide washers 1722a-c and E-rings 1723a-c are passed through guide grooves of a chassis side plate (not shown). Can be attached to the chassis side plate.
FIG. 18 is a view showing an example of a state in which the slide plate 1808 having such a structure is attached to grooves 1809a and 1809b provided on the main body chassis side plate 1809 by slide washers 1822a to 1822c and E rings 1823a to 1823c so as to be horizontally movable. However, it shows the state seen from the back side of FIG.
Further, as shown in FIG. 19 as an example of the relative positional relationship between the slide plate, the bearing portion, and the display rotation shaft, the slide plate 1908 can be horizontally moved integrally with the display rotation shaft 1904. In other words, the display rotation shaft is rotatably held by the two bearing portions 1911 and 1912 that are divided vertically. These bearings are fixed with screws, for example. Further, each bearing portion is fixed to the slide plate 1908 with, for example, screws. Further, as described above, the first gear (not shown) and the second gear (not shown) attached to the tip of the display rotation shaft mesh with each other, and this second gear is fixed on the fixed rack gear (not shown). As a result of the above, as the second gear moves horizontally on the fixed rack gear, the slide plate that holds the second gear with the gear shaft also moves horizontally, and the bearing fixed to the slide plate. The display rotation axis held by the unit also moves horizontally while rotating. And as described above, since the display rotation axis is embedded in the second casing, the entire second casing also moves horizontally while rotating at the same rotational speed as the display rotation axis. The configuration can be realized.

(Specific configuration to enable the second housing to be fixed at an arbitrary angle)
In addition, it is desirable that the electronic information display apparatus according to the present embodiment be configured so that the second casing can be fixed and used at an arbitrary angle on the first casing. An example of a specific configuration for this purpose is as follows.
As shown in FIG. 19, the display rotation shaft 1904 of the electronic information display device of this embodiment is held by bearing portions 1911 and 1912 fixed to the slide plate 1908, and the bearing portion is the display rotation shaft. Can be divided and fixed in the radial direction of the rotation axis. Further, the bearing portion is configured to generate a contact pressure sufficient to hold the display panel at a predetermined angle in the radial direction between the display rotation shaft and the bearing portion when fixed. 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, a radial receiving surface 2011a of the bearing portion (lower side) 2011 whose example is shown in FIG. 20A and a radial receiving surface 2012a of the bearing portion (upper side) 2012 shown in FIG. A configuration in which a load is applied to the shaft sandwiched between the two 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, as shown in (c), the display rotation shaft (not shown) is sandwiched between the divided bearing portions 2011 and 2012, and both the bearing portions are fastened with screws 2025 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.

(Relay board, foldable flat cable)
In addition, the electronic information display apparatus of the present embodiment is further provided on the second casing side slide portion, and includes signal lines (wire bundles) for exchanging signals between the first casing and the second casing. The relay board | substrate which relays is carried out, and this relay board | substrate may be comprised so that it may be arrange | positioned in the slide forward front, slide backward front, or side surface of a 2nd housing | casing side slide part.
Further, the electronic information display device of the present embodiment is the signal line, which connects the relay substrate and the first housing side, and can be folded along with the movement of the slide portion, and can be foldable on the bottom surface side or side surface side. You may have the flat cable located in.
The electronic information display apparatus shown in FIG. 6 is also an example of an apparatus having such a relay substrate and a foldable flat cable. In the figure, reference numeral 0616 denotes a signal line (wire bundle), and a relay board that does not appear in the figure is arranged inside thereof. Reference numeral 0618 denotes a foldable flat cable, and this example is an example provided on the side of the slide portion.
FIG. 21 shows a state in which the signal line is removed from FIG. 6 so that the relay board 2117 can be seen (the second gear and the like are also removed so that the entire shape of the relay board can be seen). The relay board of this figure is an example arranged on the side surface of the slide plate 2108 which is a part of the second housing side slide part. Reference numeral 2118 denotes a foldable flat cable.
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. The specific shape of the relay board and the specific connection method with the signal line are appropriate design matters for those skilled in the art.

(Examples of specifications of the first gear and the second gear)
Finally, examples of the first gear, the small gear of the second gear, the specifications of the large gear of the second gear, etc. suitable for realizing the above configuration are shown in this order (Table 1) to (Table 3). . As shown in the figure, the gears of this example are involute spline shapes and are external gears. Each gear shown in each of the above drawings is also an example of a gear having such specifications.
