Direction is provided with two row transmitting tubes, and each column transmitting tube is made up of multiple transmitting tubes, and two row transmitting tubes are staggered, described to receive electricity
Road board component is provided with two row reception pipes in the radial direction, and each column reception pipe is made up of multiple reception pipes, and two row reception pipes are interlocked
Arrangement, slit shadow shield presses close to placement above receiving circuit board component.Because between two row transmitting tubes between two row reception pipes
It is staggered, so code-disc size reduction can be made.
It is preferred that, the distance that two row transmitting tubes stagger be adjacent transmission tube pitch half, two row reception pipes stagger away from
From the half for adjacent reception tube pitch.
Under normal circumstances, the angle between two above-mentioned row transmitting tubes is 20 ° to 30 °, the angle between two row reception pipes
Also it is 20 ° -30 °.It is preferred that scheme be between two row transmitting tubes and two row reception pipes between angle be 25 °.
The beneficial effects of the utility model are：
After the photoelectric encoder, except securities such as " brake hards " and the high signal of requirement of real-time, and really
The high voltage, high current that driver's joystick directly controls is needed still to continue to use mechanical trip switch in fact outer, the level of joystick
The photoelectric encoder can be fully relied on to control, be easy to driver controller integrally to develop to miniaturization, it is possible to further
Improve the control accuracy of operational order.

Embodiment
Content of the present utility model is described in further detail below in conjunction with the drawings and specific embodiments：
As shown in figure 1, photoelectric encoder is by zinc die casting alloys shell 1, receiving circuit board component 3, slit shadow shield 5, code
Dish axle 6, code-disc 7, radiating circuit board component 8, cover plate 10 etc. are constituted.Receiving circuit board component 3 passes through socket 4 and radiating circuit plate
8 complete necessary circuit connection." zero-bit " indicator lamp 15 is provided with receiving circuit board component 3, " zero-bit " indicator lamp is with compiling
Code device " zero-bit " output is corresponding, is easy to the installation and debugging of encoder.It is respectively provided with simultaneously on radiating circuit board component and cover plate
There is lamp fenestra, " zero-bit " indicator lamp is stretched out outside cover plate through lamp fenestra.Slit shadow shield 5 presses close to the top of receiving circuit board component 3
Place, slit shadow shield 5 is clear optical glass material, and lighttight light-shielding pattern is printed on above, only in reception pipe is specified
Transmissive slit 19 is left in heart position, advantage of this is that improving the position detection accuracy of code-disc light tank.Code-disc is installed on code
In dish axle, code-disc is also clear optical glass material, is integrally printed on lighttight light-shielding pattern, is only stayed in the range of specified angle
There are several concentric light tanks, each light tank is corresponding with a pair of transmitting tubes and reception pipe, between transmitting tube 14 is used
The infrared light-emitting diode of standard packaging away from 2.54mm, reception pipe 13 uses connecing for spacing 2.54mm standard packaging
Diode is received, two row reception pipes are arranged on circuit board for receiving using staggered mode, the included angle A between two row reception pipes
Can it be 20 ° to 30 °, the angle between the row reception pipe of this example two is 25 °.Two row transmitting tubes are on radiating circuit plate using staggeredly
The mode of arrangement arranges that the angle between two row transmitting tubes is alternatively the angle between 20 ° to 30 °, the row transmitting tube of this example two
Also it is 25 °.The radiating circuit plate of this example and circuit board for receiving are shaped as symmetrical, two row reception pipes folder angular bisector
Included angle B with circuit board for receiving centre symmetry line is 30 ° -40 ° (referring specifically to Fig. 2), equally, the decile of two row transmitting tube angles
Line and the angle of radiating circuit plate centre symmetry line are also 30 ° -40 °, can so make full use of the plate face of circuit board, more compact
Ground arranges the position of each component.For in the switch for specifying level needs to connect, light tank is left in the correspondence position of code-disc
20, so, corresponding reception pipe can just receive the transmitting tube on radiating circuit board component on receiving circuit board component
Infrared light, by the power amplification circuit on receiving circuit board component, put high level (DC24V) or low potential (0V) pass through
External cable output.Code disk shaft is fixed together by hole jump ring 17, shell bearing 16 and axle jump ring 11 and shell 1.
Felt pad 2 is installed, to prevent the circuit on circuit board for receiving component from being sent out by metal shell below receiving circuit board component
