Next, an example that works on the above-described embodiment will be described. Examples described below are examples in which the display device of the above-described embodiment is applied to a navigation device mounted on a moving body such as a vehicle.

[0032] (Appearance of navigation device)

FIG. 3-1 to FIG. 3-3 are explanatory views ((Part 1) to (Part 3)) showing the appearance of the navigation device that works on the present embodiment. As shown in FIG. 3-1 to FIG. 3-3, the navigation device 300 according to the embodiment has a rectangular-shaped navigation device body 301! It is installed on a moving body such as a vehicle with the side facing. In addition, a slit 301 a is opened on the surface represented by the symbol A in the navigation device body 301. The slit 301a is an opening that is opened so as to have a predetermined area on the surface represented by the symbol A in the navigation device body 301. Here, the predetermined area is an area where the flexible display 302 is sufficiently displaceable in and out of the housing through the slit 301a.

[0033] Inside the navigation apparatus main body 301 is a long flexible display 302. 1S Contained in a wound state in the longitudinal direction. As the flexible display 302, for example, a flexible display having physical flexibility can be used. Since it is a well-known technique, the force of omitting illustration and explanation The flexible display has a structure in which a light emitting element is sandwiched between films such as plastics.

[0034] Examples of the light-emitting element in the flexible display include an organic EL element using an organic EL (Oarganic Electroluminescence) phenomenon, a liquid crystal element that selectively transmits backlight light by controlling the orientation of liquid crystal molecules, Alternatively, an electronic powder fluid can be used.

The flexible nore display 302 is provided with feed holes 302 a at regular intervals near both ends in the width direction perpendicular to the longitudinal direction of the flexible nore display 302. The feed hole 302a is an opening provided in a straight line between both ends in the longitudinal direction along the widthwise end of the flexible display 302. The feed hole 302a is engaged with a gear of a geared shaft (see reference numerals 410 and 420 in FIG. 4) and guides the flexible display 302 in a predetermined direction.

One end side in the longitudinal direction of the flexible display 302 is attached to a geared shaft (see reference numeral 410 in FIG. 4) provided in the navigation apparatus main body 301. The flexible display 302 is urged by a urging mechanism (not shown) provided in the navigation device main body 301 by a geared shaft (see reference numeral 410 in FIG. 4).

[0037] The other end in the longitudinal direction of the flexible display 302 is attached to a handle 303 positioned outside the navigation device main body 301 through the slit 301a. The outer size of the handle 303 is larger than the size of the opening of the slit 301a. As a result, the handle 303 cannot pass through the slit 301a. That is, in the flexible display 302, the other end in the longitudinal direction is always positioned outside the navigation device main body 301! /.

[0038] The navigation apparatus main body 301 is provided with a stay 304 having protrusions capable of holding both ends of the handle 303. The protrusion has the same height as the handle 303. The flexible display 302 was pulled out of the navigation device body 301. By hooking the handle 303 on the protrusion of the stay 304 in this state, the flexible display 302 can be restrained from being squeezed and fixed stably.

[0039] When the handle 303 is moved away from the navigation device main body 301, the flexible display 302 is fed out to the outside of the navigation device main body 301 as the handle 303 is moved. . In addition, the external force applied to the handle 303 is released while the flexible display 302 is pulled out of the navigation device main body 301 with the external force applied to the handle 303, such as by gripping and pulling the handle 303 by the biasing mechanism described above. When the user presses a display accommodation button (not shown), the flexible display 302 returns to the wound state.

Next, with reference to FIGS. 4 and 5, the internal structure of the navigation device main body 301 that is useful in the present embodiment will be described. FIG. 4 is a cross-sectional view of the navigation device when the flexible display is accommodated. FIG. 5 is a cross-sectional view of the navigation device when the flexible display is extended. As shown in FIGS. 4 and 5, the navigation apparatus main body 301 includes a geared shaft 410, a geared shaft 420, and a reflective photosensor unit 430.

[0041] The geared shaft 410 includes a shaft 410a, two gears 411, a gear 412, a stopper 413, a stopper release lever 414, and a mainspring panel (not shown). The gear 411 is a gear whose pitch is equivalent to the interval between the feed holes 302 a provided in the flexible display 302. A gear 412 is a gear for a stopper and is a gear having an arbitrary pitch. The Stotto 413 has a claw portion 413b that rotates around a fixed portion 413a. Similarly to the stopper 413, the stopper release lever 414 has a claw portion 414b that rotates around the fixed portion 414a.

[0042] On the geared shaft 410, a spring or a panel, which is wound counterclockwise in FIGS. 4 and 5, from one side of the cross-sectional views shown in FIGS. 4 and 5, has one end. The other end of the navigation apparatus main body 300 is fixed to the shaft 410a on the housing surface (hereinafter simply referred to as “nozzle surface”). The mainspring panel force is also fixed to the shaft 410a around the gear 41 2 force shaft 410a at a predetermined distance.

[0043] A stopper 413 is attached to the housing surface near the gear 412. The claw portion 413b of the stopper 413 is applied to the tooth portion. Further, a stopper release lever 414 is attached to the lower housing surface of the stopper 413. The stopper release lever 414 is provided with a motor. The first gear 411 is fixed to the shaft 410a around the shaft 410a at a predetermined distance from the gear 412, and the second gear 411 is fixed to the shaft 410a in the same form at a predetermined distance. It is fixed. In FIGS. 4 and 5, the second gear 411 is a shadow of the first gear 411.

[0044] The geared shaft 420 includes a shaft 420a, two gears 421, and a gear 422.

Here, the gear 421 has the same shape as the gear 411, and the gear 422 has the same shape as the gear 412. That is, the geared shaft 420 is obtained by removing the stocko 413, the stopper release lever 414, and the mainspring panel from the geared shaft 410 described above, and the other shapes are the same.

Force not shown The reflection type photosensor unit 430 includes a reflection type photosensor, an amplifier, and a microprocessor. The reflection type photosensor has a light receiving element and a light emitting element facing in the same direction. The light receiving element emits light emitted from the light emitting element to the gear 422, and the light receiving element detects the presence or absence of reflected light. It is a sensor provided. An amplifier is an electronic circuit having a function of amplifying and outputting an input signal having the power of a reflective photosensor. A microprocessor is an integrated circuit that has the function of AZD-converting an input signal from an amplifier into a pulse signal.

That is, the reflective photosensor unit 430 is a measuring device having a function of outputting a signal detected by the reflective photosensor as a signal that can be processed by the CPU. The reflection type photosensor unit 430 is installed on a housing surface that can apply light to the position of the tooth portion of the gear 422 of the geared shaft 420.

As shown in FIG. 4, when the flexible display 302 is housed in the main body, it is wound on the outer periphery of the geared shaft 410. Here, when the user needs detailed information, the user tries to pull out the flexible display 302 forward (leftward in FIGS. 4 and 5; hereinafter simply referred to as “forward”). At this time, the flexible display 302 receives a forward force and starts to move forward.

Here, as described above, in the vicinity of the end of the flexible display 302 in the width direction, A feed hole 302a is opened. The feed hole 302a described above is meshed with the gear 411 of the geared shaft 410. When the flexible display 302 is displaced forward, the geared shaft 410 receives torque in the direction of arrow T in FIG. Start rotating in the direction. Further, the gear 421 of the geared shaft 420 is also mated with the feed hole 302a described above, whereby the geared shaft 420 also starts to rotate in the same manner as the geared shaft 410.

In addition, the reflective photosensor unit 430 applies light to the tooth portion of the gear 422 of the rotating geared shaft 420. Each time the gear 422 of the geared shaft 420 rotates, the presence or absence of reflection by the teeth is repeated, and the presence or absence of the above-mentioned is detected by the reflective photosensor unit 430 and converted into a pulse signal. After that, the above-mentioned noise signal is counted, and the feed amount from the accommodation position of the flexible display 302 is calculated. When the flexible display 302 has a desired length, the user hooks the handle 303 on the above-described stay 304 to fix the flexible display 302. Further, by selecting the stay 304 in a position that matches the length of the flexible display 302, the user can suppress the stagnation of the flexible display 302 and stably fix it.

[0050] As described above, the mainspring panel is fixed to the geared shaft 410. Due to the restoring force of the mainspring panel described above, the geared shaft 410 is applied with a force that rotates counterclockwise in FIGS. 4 and 5. However, as described above, the stopper 413 is wound on the gear 412 of the geared shaft 410. Due to this stopper 413, the geared shaft 410 has a ratchet structure and acts against the restoring force described above, and therefore acts counterclockwise in FIGS. 4 and 5. Resilience is limited.

Next, the operation of each component when the flexible display 302 is accommodated will be described. When the user accommodates the flexible display 302, first, the user releases the above-mentioned handle 303 also with the stick 304 force. Then, the user presses a display accommodation button (not shown). When the display accommodation button is pressed, the claw portion 414b of the stopper release lever 414 is rotated in the direction of the stopper 413 by the motor, and the stopper 413 is pushed up. As described above, the stopper 413 is engaged with the gear 412 of the geared shaft 410, but the stopper 413 is separated from the gear 412 by being pushed upward by the stopper release lever 414. At this time, the geared shaft 410 rotates counterclockwise in FIGS. 4 and 5 by the restoring force of the mainspring panel fixed to the geared shaft 410.

[0053] Since one end side of the flexible display 302 is fixed to one point on the outer periphery of the geared shaft 410, the flexible display 302 is rotated by rotating the geared shaft 410 counterclockwise as described above. Displaces to the right in Figs. As a result, an operation opposite to that in the above-described extraction is performed. When the flexible display 302 is completely accommodated, the pulse count amount of the reflective photosensor unit 430 described above is reset.

[0054] (Hardware configuration of navigation device 300)

Next, the hardware configuration of the navigation apparatus 300 that is useful in the present embodiment will be described with reference to FIG. FIG. 6 is a block diagram showing the hardware configuration of the navigation device. In FIG. 6, the navigation device 300 is mounted on a moving body such as a vehicle, and includes a CPU 601, a ROM 602, a RAM 603, a magnetic disk drive 604, a magnetic disk 605, an optical disk drive 606, and an optical disk 607. , Audio iZF (Interface) 608, Microphone 609, Speaker 610, Human power device 611, Video I / F612, Flexible display 302, Camera 613, Communication IZF614, 0-3 A boot 615 and various sensors 616 are provided. In addition, the components 302 and 601 to 616 are connected to each other by a nose 620.

First, the CPU 601 governs overall control of the navigation device 300. The ROM 602 stores programs such as a boot program, a current location specifying program, a route search program, a route guidance program, a voice generation program, a map information display program, a communication program, a database creation program, and a data analysis program. The RAM 603 is used as a work area for the CPU 601.

[0056] The current location specifying program is, for example, based on output information of a GPS unit 615 and various sensors 616 described later, and the current location of the vehicle (current location of the navigation device 300). Point).

[0057] The route search program uses the map information recorded on the magnetic disk 605 or the optical disk 607, which will be described later, and the optimum route from the departure point to the destination point, and when the departure from the optimum route Search for a detour route. Here, the optimum route is a route with the lowest cost to the destination point or a route that best meets the conditions specified by the user. The guidance route searched by executing the route search program is output to the audio IZF 608 and the video IZF 612 via the CP U601.

[0058] The route guidance program is derived from the guidance route information searched by executing the route search program, the current location information of the vehicle specified by executing the current location specifying program, the magnetic disk 605 or the optical disc 607. Real-time route guidance information is generated based on the read map information. The route guidance information generated by executing the route guidance program is output to the audio IZF608 and video IZF612 via the CPU 601.

[0059] The sound generation program generates tone and sound information corresponding to the pattern. In other words, based on the route guidance information generated by executing the route guidance program, the virtual sound source corresponding to the guidance point is set and the voice guidance information is generated. The voice guidance information includes, for example, an alarm to turn right and left according to the route, a warning to decelerate before the right and left turning point, information about a detour route when the right or left fails, Includes guidance information that you should turn back if you fail to turn left or right. The generated voice guidance information is output to the voice IZF 608 via the CPU 601.

The map information display program causes the flexible display 302 to display the map information read from the magnetic disk 605 or the optical disk 607 by the video I / F 612.

The magnetic disk drive 604 controls data reading / writing to the magnetic disk 605 according to the control of the CPU 601. Data written by the control of the magnetic disk drive 604 is recorded on the magnetic disk 605. For example, HD (node disk) or FD (flexible disk) can be used as the magnetic disk 605.

[0062] The optical disk drive 606 is connected to the optical disk 607 according to the control of the CPU 601. Controls reading and writing of data. The optical disk 607 is a detachable recording medium from which data is read according to the control of the optical disk drive 606. As the optical disc 607, a writable recording medium can be used. Further, the removable recording medium may be a power MO of the optical disk 607, a memory card, or the like.

[0063] As an example of information recorded on the magnetic disk 605 or the optical disk 607, there is map information used for route search or route guidance. The map information includes background data that represents points (features) such as buildings, rivers, and surface points, and road shape data that represents the shape of the road. The original drawing.

[0064] The road shape data further includes traffic condition data. Traffic condition data includes, for example, the presence or absence of traffic lights or pedestrian crossings, the presence or absence of highway entrances and junctions, the length (distance) of each link, road width, direction of travel, road type (high speed) Roads, toll roads, and general roads) are included.
