A kind of hand-held fundus camera, including lens module, imaging sensor, the drive lens module or imaging sensor edge
Transmission mechanism that the optical axis direction of the lens module is moved, the motor of the driving transmission mechanism operating, with the figure
As processor and button that sensor is connected with motor, the button generates the first input based on pressing or touch event
With the second input；When the processor receives first input, the processor is to the electrical power and controls described
Motor drives the transmission mechanism operating, so as to drive the optical axis of the lens module or imaging sensor along the lens module
Direction is moved, and then realizes auto-focusing；When the processor receives second input, hand-held eyeground phase
Machine is completed to take pictures, and the processor is powered off to the motor.
Further, the button is button, and the button can be pressed into the first pressing thresholding and the from initial position
Two pressing thresholdings, the first pressing thresholding is different from the described second pressing thresholding；When the button is pressed into from initial position
First input is formed during the first pressing thresholding；The second pressing thresholding is pressed into when the button presses thresholding position from first
When formed it is described second input.
Further, the button includes button and the touch sensor being arranged on the button；Described touch passes
Sensor is used to detect the touch event in the touch sensor surface, and forms first input；The button can be from
Initial position is pressed into the first pressing thresholding；Described is formed when the button is pressed into the first pressing thresholding from initial position
Two inputs.
Further, the hand-held fundus camera has handle, and the handle has the first side wall just to operator
And back to the second sidewall of operator, the button is located at the first side wall.
Further, the hand-held fundus camera has handle, and the handle has the first side wall just to operator
And back to the first side wall of operator, the button is located at the first side wall.
Further, when the processor receives second input, the processor is powered off to the motor immediately.
Further, the hand-held fundus camera is completed after taking pictures, and the operator does not have in a preset time
The hand-held fundus camera is operated, now the processor is powered off to the motor.
The beneficial effects of the invention are as follows：Compared to prior art, hand-held fundus camera of the present invention passes through button, processor
To control the break-make of the motor electric energy, so as to reduce unnecessary power consumption, the hand-held eyeground is effectively extended
The cruising time of camera.
Brief description of the drawings
Fig. 1 show the schematic perspective view of hand-held fundus camera of the present invention.
Fig. 2 show the schematic perspective view of another embodiment of hand-held fundus camera of the present invention.
Fig. 3 show the structural representation of button.
Fig. 4 show the structural representation of another embodiment of button.
Embodiment
Refer to shown in Fig. 1, hand-held fundus camera 100 of the present invention includes lens barrel 10 and is engaged with the lens barrel 10
Main frame 20, the main frame 20 has the handle 21 gripped for operator, and the handle 21 has the first side just to operator
Wall 211 and the second sidewall 212 back to operator.The lens barrel 10 is built-in with to carry out the lens module of optical imagery.
The main frame 20 is built-in with imaging sensor, motor and processor.Button 22 is provided with the handle 21.The button 22
It can be located on the first side wall 211（As shown in Figure 1）, can also be located in the second sidewall 212（As shown in Figure 2）.
The hand-held fundus camera 100 also has the optical axis side for driving the lens module or imaging sensor along the lens module
To the transmission mechanism moved.The processor controls the motor to drive according to the operation result of automatic focusing evaluation function
The dynamic transmission mechanism drives the optical axis direction of the lens module or imaging sensor along the lens module to move, from
And realize auto-focusing.When by the mobile lens module to realize focusing, the transmission mechanism is located at the lens barrel 10
It is interior.When by mobile described image sensor to realize focusing, the transmission mechanism is located in the main frame 20.
The button 22 generates the first input and the second input based on pressing or touch event.When the processor is received
During first input, the processor is to the electrical power and controls the motor to drive the transmission mechanism operating, from
And drive the optical axis direction of the lens module or imaging sensor along the lens module to move, and then realization is automatic right
It is burnt.When the processor receives second input, now the processor is powered off to the motor immediately, to save electricity
Can, the hand-held fundus camera completes to take pictures.Certainly, in other embodiments, the processor can also be according to operator
Hand-held fundus camera 100 whether is operated to decide whether to power off to the motor.For example, within a certain period of time, operation
Person does not operate the hand-held fundus camera 100, then the processor is powered off to the motor.Because motor is in energization shape
State but when not working, motor still needs to consume electric energy, so accelerates the depletion rate of the fundus camera energy content of battery, shortens
The cruising time of fundus camera.And hand-held fundus camera 100 of the present invention controls the electricity by the button 22, processor
It is electromechanical can break-make so that less unnecessary power consumption, effectively extends the continuation of the journey of the hand-held fundus camera 100
Time.
Fig. 3 show one embodiment of the button 22.The button 22 is button, and the button can be from initial bit
Put（As shown in Figure 3 a）It is pressed into the first pressing thresholding（As shown in Figure 3 b）With the second pressing thresholding（As shown in Figure 3 c）, described
One pressing thresholding is different from the described second pressing thresholding.Formed when the button is pressed into the first pressing thresholding from initial position
First input.Second input is formed when the button is pressed into the second pressing thresholding from the first pressing thresholding position.
Fig. 4 show another embodiment of the button.The button 22 ' includes button 221 ' and is arranged on described
Touch sensor 222 ' on button 221 ', the button 221 ' can be from initial position（As shown in fig. 4 a）It is pressed into first
Press thresholding（As shown in Figure 4 b）.The touch sensor 222 ' is used to detect the touch thing in the touch sensor surface
Part, and form first input.Institute is formed when the button 221 ' is pressed into the first pressing thresholding from initial position
State the second input.
Compared to prior art, hand-held fundus camera 100 of the present invention passes through the button 22,22 ' and processor
To control the break-make of the motor electric energy, so that less unnecessary power consumption, effectively extends the hand-held eyeground
The cruising time of camera 100.
In particular, for the person of ordinary skill of the art, that is made under the teachings of the present invention is directed to
The equivalence changes of the present invention, should be included in the scope that scope of the present invention patent is advocated.
