Detailed ways

Some embodiments of the present invention are described in detail as follows. However, the invention may also be practiced broadly in other embodiments than those described in detail, and the scope of the invention is not limited only by the following claims.

Furthermore, various parts of elements of the present invention are not drawn to scale. Certain dimensions have been exaggerated compared to other relevant dimensions to provide a clearer description and understanding of the invention.

Also, although the embodiments drawn here are shown in two dimensions with width and depth at different stages, it should be clearly understood that the regions shown are only part of the three-dimensional space of the device. In contrast, in the manufacture of actual components, illustrated regions have three-dimensional length, width and height.

A preferred embodiment of the present invention is a detection system of an imaging device. The aforementioned imaging device may be an upright/platform dual-purpose scanner. FIG. 1A and FIG. 1B are schematic views of the above-mentioned upright/flat-bed scanner 100 when performing flat-bed and upright operation modes, respectively. Referring to FIG. 1A, the vertical/platform dual-purpose scanner 100 of the present invention is illustrated with rectangular coordinates, and the longest axis of its geometric shape is marked as "L"; the so-called platform placement mode, that is, "L" is approximately parallel to the X-Y plane , and the gravity direction of the upright/platform dual-purpose scanner 100 is the Z-axis direction perpendicular to the X-Y plane. While FIG. 1B shows the upright placement mode of the upright/platform dual-purpose scanner 100 of the present invention, that is, "L" is approximately parallel to the Z-axis direction of the gravitational direction.

The connection mode of the above detection system can be represented by the block diagram in FIG. 2 . In this embodiment, the detection system 110 is installed in the upright/platform dual-purpose scanner 100, which at least includes a detection device 120 and a detection control device 130, and the detection control device 130 can be connected with other systems of the upright/platform dual-purpose scanner 100 , for example, the imaging device system 140 is connected to the imaging control system 142 . When the user changes the placement mode of the scanner, the detection device 120 installed on the scanner can detect the placement mode of the scanner according to the action of a physical force, such as gravity, and then The placement mode transmits a set of position signals to the detection control device 130 to notify the detection control device 130 to perform appropriate operation mode switching as the scanner placement mode changes. Wherein, the detecting device 120 is a detector designed using the principle of gravity, such as a strain gauge.

Because there are many software/hardware systems that cannot be applicable to both the vertical operation mode and the platform operation mode in operation. Therefore, when the above-mentioned scanner switches between the upright and flat-bed operation modes, some execution systems of the upright/flat-bed dual-purpose scanner must also switch accordingly. Therefore, after the detection control device 130 receives the signal from the detection device 120, the detection control device 130 will output a set of switching signals to the execution system of the scanner according to the scanner operation mode detected by the detection device 120, such as the imaging element System 140 and camera control system 142 . Wherein, the execution system mentioned above also includes a power supply system, an LCD display system, a start-up operation system for the drive motor, and a software control and display system, etc. and other such software/hardware execution systems. Wherein, the above-mentioned switch signal is a signal corresponding to the above-mentioned placement mode.

The so-called switching operation mode in the present invention refers to the upright/platform dual-purpose scanner 100 and the execution scanner, corresponding to the difference in the placement mode, the scanning steps of the imaging device system 140 and the imaging control system 142 also need to follow. corresponding to. Therefore, the detection system of the present invention can make the imaging device system 140 and the imaging control system 142 automatically switch to the operation mode of the corresponding placement mode.

Fig. 3 is a flowchart for implementing the detection system described above. When the user changes the placement mode of the imaging device, for example, in the step 150 of placing the scanner, the upright/platform dual-purpose scanner is changed from a platform type to an upright placement mode, and the detection device on the scanner will automatically detect And determine whether the placement mode of the upright/platform dual-purpose scanner is upright or platform (step 160 ). The above-mentioned judging mechanism is to judge the placement mode of the upright/platform dual-purpose scanner through the principle of gravity. According to the difference of the upright/platform placement mode, the above-mentioned detection device will respectively transmit a group of different signals to the control system of the upright/platform dual-purpose scanner after discriminating the placement mode. After the control system receives the signal from the detection device, the control system will switch all the software/hardware execution systems that need to be changed when performing scanning in the upright/platform dual-purpose scanner (step 170).

When the detection device determines that the placement mode of the upright/platform dual-purpose scanner is the platform type, the detection device will send a set of position signals to the control system, as shown in path A. After the control system receives the above signals, it will output a set of switching signals to switch and execute the functional mechanism related to the platform operation mode, as shown in step 180 of executing the platform operation mode.

On the other hand, when the detection device determines that the placement mode of the upright/platform dual-purpose scanner is upright, the detection device will send another set of position signals to the control system, as shown in path B. After the control system receives the above signal, it will switch and execute the functional mechanism of the upright operation mode (step 190).

A preferred embodiment of the present invention is a detection device for a vertical-platform dual-purpose scanner. 4A and 4B are schematic diagrams of an upright/platform dual-purpose scanner 100 equipped with a set of detection devices according to the present invention. The above detection device includes a set of fixed elements, such as the elbow 200 in the figure, and a set of movable elements inside the elbow 200 , such as the ball 210 in the figure.

The above-mentioned signal sources, not shown in the figure, are respectively connected to the control system of the upright/platform dual-purpose scanner 100, such as a microprocessor, and when the ball 210 moves to the In position a or position b, the above-mentioned signal sources will respectively transmit different position signals to inform the control system to switch the operation mode of the upright/platform dual-purpose scanner to the platform type or upright operation mode.

In the above-mentioned device, the ball 210 will move to different positions along various arc paths in the curved tube 200 according to the different placement modes of the upright/flat-bed dual-purpose scanner. As shown in FIG. 4A , when the user operates the upright/platform dual-purpose scanner 100 in the platform placement mode, the ball 210 will move to the first position a in FIG. 4A due to the influence of gravity, and simultaneously drive Signal source at position a. At this time, if the user starts the upright/platform dual-purpose scanner 100 , or the upright/platform dual-purpose scanner 100 has been started up, the signal source at position a will send a set of position signals to the control system. Next, the control system will switch the operation mode of the upright/platform dual-purpose scanner 100 to the platform operation mode, for example, switch the presentation mode of the image to a straight file.

When turning upright, it is subjected to the action of gravity and moves along the arc path to the second position b in FIG. 4B , and simultaneously drives the signal source at position b. At this time, if the user starts the scanner 100 upright/platform, or the upright/platform scanner 100 has been started, the signal source at position b will send a set of position signals to the control system. Next, the control system will switch the operation mode of the upright/platform dual-purpose scanner 100 to the upright operation mode, for example, switch the presentation mode of the image to a horizontal document.

In the above embodiments, it should be noted that the installation position of the detection device of the present invention in the upright/platform dual-purpose scanner is not limited to the positions as shown in FIGS. 4A and 4B . As long as the function of the original components of the upright/platform dual-purpose scanner is not disturbed, and the position that can faithfully reflect the placement mode of the upright/platform dual-purpose scanner can be used for installing the detection device of the present invention.

Another preferred embodiment of the present invention is a vertical-platform dual-purpose scanner detection device. FIG. 5A is a schematic diagram of a chassis 220 , a shaft 230 , and a shaft support 240 installed in an upright/flat-bed scanner 100 . The feature of this embodiment is that the stress and strain gauges are respectively installed on a set of side surfaces and a set of bottom surfaces of the supporting object 240 at both ends of the shaft, as shown in positions A1, A2, B1, and B2 in FIG. 5A. Wherein, the stress strain gauge mentioned above can convert the stress it bears into voltage or current. Therefore, in the present invention, the placement mode of the upright/platform dual-purpose scanner 100 can be determined by collecting and comparing the voltage or current from the strain gauges at the above-mentioned positions A1, A2, B1, and B2. In other words, the above-mentioned stress strain gauges are respectively connected to a set of logic circuits that can collect and compare the voltage or current of the above-mentioned stress strain gauges, not shown in FIG. 5A . When the voltages or currents of the above-mentioned stress and strain gauges are output to the above-mentioned logic circuit and compared, the above-mentioned logic circuit will output a set of signals to the control system of the vertical/platform dual-purpose scanner 100, such as a microprocessor device, not shown in Figure 5A. According to the comparison result, the above logic circuit will send different signals to the above control system to notify the above control system to switch to an appropriate operation mode according to the current placement mode of the upright/platform dual-purpose scanner.

FIG. 5B is a schematic side view of placing the upright/flatbed scanner in FIG. 5A in a flatbed device mode. When the user lays the upright/platform dual-purpose scanner 100 flat, the gravity effect felt by the stress-strain gauges at the above-mentioned positions A1 and A2 will be greater than the gravity effect felt by the stress-strain gauges at the above-mentioned positions B1 and B2 stronger. Therefore, when the upright/platform dual-purpose scanner 100 is placed flat, the voltage (V _A1 +V _A2 ) or current (I _A1 +I A2 ) from the strain gauges at positions A1 and _A2 will be higher than those from position B1 The voltage (V _B1 +V _B2 ), or current (I _B1 +I _B2 ) of the strain gauge with the stress of B2 is stronger. The relationship between them can be represented by the following formula 1 or formula 2.

V _A1 +V _A2 >V _B1 +V _B2 (Equation 1)

I _A1 +I _A2 >I _B1 +I _B2 (Equation 2)

When the placement mode of the upright/platform dual-purpose scanner is flat, the above logic circuit will obtain the comparison result of the above formula 1 or formula 2. At this time, the logic circuit sends a set of signals to the control system of the upright/platform dual-purpose scanner, so as to notify the control system to switch the operation mode to the flatbed scanner.

FIG. 5C is a schematic side view of the upright/platform dual-purpose scanner in FIG. 5A when it is placed upright. When the user places the upright/platform dual-purpose scanner 100 in an upright position, the stress and strain gauges at the positions B1 and B2 will be subjected to the gravitational force compared to the stress and strain gauges at the positions A1 and A2. Gravity is stronger. Therefore, when the upright/platform dual-purpose scanner is placed in the upright mode, the voltage (V _B1 +V _B2 ) or current (I _B1 +I _B2 ) obtained by the strain gauges at positions B1 and B2 will be It is stronger than the voltage (V _A1 +V _A2 ) or current (I _A1 +I _A2 ) obtained by the stress strain gauges at positions A1 and A2. The relationship between them can be expressed as follows.

V _A1 +V _A2 >V _B1 +V _B2 (Formula 3)

I _A1 +I _A2 >I _B1 +I _B2 (formula 4)

When the placement mode of the upright/platform dual-purpose scanner is upright, the above logic circuit will obtain the comparison result of the above-mentioned formula 3 or formula 4. At this time, the logic circuit will output another set of signals to the control system of the upright/platform dual-purpose scanner to notify the control system to switch the operation mode of the upright/platform dual-purpose scanner 100 to the upright scanner.

To sum up the above, the present invention switches between the upright/platform operation mode through a detection device using the principle of gravity, so that the user can simultaneously have the upright/platform operation system in one camera device. More preferably, the above camera device can automatically switch its operation mode as the user's placement mode changes. Therefore, the present invention can be effectively applied to an operating mode switching system of an upright/platform dual-purpose scanner, so that the above-mentioned upright/platform dual-purpose scanner can be adjusted according to different placement modes of the upright/platform dual-purpose scanner Switching of the operation mode is performed automatically.
