Abstract

The utility model relates to a photographing device, in particular to a remote-controlled and automatic photographing device used for the automatic photographing of the camera, comprising two portions of a mini-type transmitter and a remote-control receiver of the camera shutter. The utility model overcomes the problems that the traditional automatic photographing device of the camera has fixed action time of automatic photographing delaying and the action of the camera shutter can not be controlled by the photographing people. The momentary optimum gesture considered by the photographing people and the camera shutter action can be simultaneously conducted in order to guarantee the quality and the effect of the photographed photo.

Description

Remote-controlled self-timer for camera

The utility model relates to a kind of photographic goods, the camera remote control automatic timer of autodyning especially for camera.

When using the camera of existing attached self-timer to autodyne photography, the person of taking pictures must at first wind up to automatic timer, and presses shutter, walks rapidly to the position of taking pictures then, sets posture, automatic timer through one section time-delay after, shutter action is finished the auto heterodyne process of photograph.

The problem that existing delayed action exists is: fix the actuation time of automatic timer time-delay; whether the person that no matter do not take pictures is ready in the position of taking pictures; camera shutter all can move on time, so defective such as the photo of shooting nature of expression occurs through regular meeting, and is stiff or close one's eyes.

The purpose of this utility model is at the problems referred to above, proposes a kind of novel camera remote control automatic timer.

The technical solution of the utility model drives receiver by a microtransmitter and camera shutter remote control and forms.

Further specify the technical solution of the utility model below in conjunction with accompanying

drawing

1,2,3,4.

At first utilize joint cover 8 that receiver and camera are fixed on the tripod, work feather key switch 15 is upwards dialled, spring 34 is stretched, shutter is pressed a transverse arm 9 with moving on the work slide bar 29, while microswitch 32 normally closed contact closures, connect receiver power supply, work indication light emitting diode 16 is luminous, when moving to certain position on the work slide bar 29, horizontal bolt 28 heads of locking snap under the effect of lever stage clip 38 in the chamfered groove on the work slide bar, and slide bar 29 lockings of will working are regulated shutter again and pressed a lifting screw 10, make and press 14 and be positioned at camera shutter button top, this moment, receiver was in the preliminary work state.The person of taking pictures gets final product the handhold mini-size transmitter, to the position of taking pictures; Press remote control buttons switch 2, transmitter then sends the radiowave through voice modulation, after receiver receives and amplifies, relay 32 adhesives, motor 24 rotates with power connection, and by

gear

20 and 22 engagements of transmission gear wheel, 19 on cam rotates with gear wheel 22, cam rotation is pressed and is touched lever 26, lever 26 is pushed the horizontal bolt 28 of locking aside by trundle 27, and 29 of slide bars of work drive shutter and press a transverse arm 9 and move downward under the effect of spring 34, and the rubber shutter is pressed 14 and depressed the camera shutter button, make the best looks and the camera shutter action of the person's of taking pictures self-induction keep finishing the auto heterodyne process of remote control synchronously.The microswitch normally closed contact is disconnected again in the receiver simultaneously, cuts off receiver power supply, and work indication light emitting diode extinguishes.When taking a photo, then repeat aforesaid operations.

As follows to the receiver control shutter principle of work block diagram illustrating of the microtransmitter circuit theory of Fig. 5 and Fig. 6 below:

The higher-order of oscillation that carrier frequency oscillation produces, and modulate by audio frequency oscillator, when pressing teleswitch, energized, then send the high-frequency electric wave of certain voice modulation, after the detection of receiver superregenerative detector, output audio signal is again after the audio frequency frequency-selecting amplifier amplifies, make the relay adhesive, motor connecting power rotates, and drives shutter action by shutter driver, and the microswitch normally closed contact disconnects simultaneously, receiver power supply is cut off, in order to prevent the phase mutual interference of many camera remote control automatic timers, transmitter can adopt different audio frequency to modulate, and as long as the frequency-selecting of the frequency-selecting amplifier of receiver is identical with the audio frequency of transmitter modulation.

The utility model advantage is: the action of camera shutter is by the person of taking pictures oneself remote control, and the instantaneous best looks of the person's of taking pictures self-induction and camera shutter action are kept synchronously, thereby guaranteed the quality and the effect of taking pictures.In addition, mix this remote control automatic timer, also can possess above-mentioned Self-timer for the camera that original nothing is autodyned.

Embodiment:

Microtransmitter adopts simple ultra-high-frequency transmitter, can make transmitter not need emitting antenna, and is easy to use.In the accompanying drawing 1, a transistor produces the higher-order of oscillation, and other transistor produces audio oscillation and the ultrahigh frequency oscillistor is modulated, and sends the ultra-high-frequency wave through voice modulation, and the microtransmitter shell is made of plastic.

When microtransmitter emission remote control ultra-high frequency signal, remote-control receiver is through transistor superregenerative detection output audio signal, amplify through the transistor frequency-selecting amplifier again, make auxiliary reclay 23 adhesives, connecting motor 24 rotates, by after gear 20 and gear wheel 21 decelerations cam 19 is rotated thereupon, when cam is pressed when touching lever 26 gradually, lever 26 is pushed the horizontal bolt 28 of locking aside by trundle 27, work slide bar 29 is under the effect of spring 34, drive shutter and press a transverse arm 9 and move downward, the rubber shutter on the transverse arm is pressed 14 and is depressed the camera shutter button, finishes the process that remote control is autodyned.
