[embodiment]
See also illustrated in figures 1 and 2, the Cash collecting equipment that single display screen two directions of the present utility model show, comprise a Device Host 1 and a code keypad (not shown) that split is provided with, described Device Host 1 comprises forward operating surface 11 and a rear end face 12 backward, described operating surface 11 is provided with an operation keyboard 13, also be provided with a display screen 14 on the described Device Host 1, this display screen 14 rotatably is connected the top of described Device Host 1.Described operating surface 11 and rear end face 12 are an inclined-plane, the intersection of the two is the top of described Device Host 1, one turning axle 15 is located at the intersection place of described operating surface 11 and rear end face 12, described display screen 14 is fixed on the runing rest 2, the middle part of this runing rest 2 rotatably is set on the described turning axle 15, this display screen 14 is had show and show backward two display directions forward.Be close to described operating surface 11 when described display screen 14 shows forward, be close to described rear end face 12 when showing backward.Described runing rest 2 can manually rotate, also can be by a micromachine (not shown) driven rotary by software control.
The top of described Device Host 1 also is provided with one and is used to respond to the sensor 3 that described display screen 14 shows or show backward two kinds of show states forward, described sensor 3 can be reflective infrared eye, or the microswitch detecting device, go back or the direction inductor device.This sensor 3 is covered by this display screen when described display screen shows forward or show backward, and as shown in Figure 3 and Figure 4, this sensor 3 is connected a testing circuit that is used for detecting described display screen 14 show states, sensor 3 returns logical signal " height " or " low ", indicates former and later two directions of runing rest 2 respectively.Wherein, the sensor 3 that Fig. 3 describes is a kind of reflective infrared eyes, when this sensor 3 be blocked (being in this position) such as display screen, the infrared light that sensor 3 sends will be reflected and be received by the inductor of sensor 3, and make the circuit output low level, and when not having object to block sensor 3 (being in the another location such as display screen 14), circuit output high level.The sensor 3 that Fig. 4 describes is microswitch detecting devices, promptly use microswitch instead of optical electric transducer as the detecting device that detects screen position, when display screen is in a certain position, push down microswitch, circuit output high level, when display screen not in this position, circuit output low level then.
The utility model makes the display screen 14 can customer-oriented according to actual needs or cashier by above-mentioned structural design, return the information of display screen 14 by sensor 3 towards direction, return display screen 14 by software receiving sensor 3 and control to show whether displaying contents needs to do 180 degree reversings so that displaying contents is the forward demonstration towards the information of direction, specific as follows described.
As shown in Figure 5, power-up initializing during normal boot-strap, software at first obtains display screen 14 state orientations that sensor 3 returns and judges display screen 14 display directions according to application state, if " 1 " expression shows forward, " 0 " expression shows backward, if the state value that software obtains is " 1 ", control display screen 14 is pressed forward and shown, if the state value that software obtains is " 0 ", then control display screen 14 shows by reverse 180 degree modes.Again as shown in Figure 6, when display screen 14 when changing, the display direction state variation of the display screen 14 that software returns by the mode detecting sensor 3 of poll or interruption, the content Rotate 180 degree of control display screen 14.
The utility model provides two kinds of methods to realize the counter-rotating of the displaying contents of display screen 14:
First kind, by revising the method that display screen ranks start address is provided with
This method is applicable to the display screen 14 that display screen 14 ranks start addresses can be set.The line number of supposing display screen 14 is 0～n, and column number adds up to 0～m, then when display screen is in the position that shows forward, initial behavior the 0th row of ranks is set, and n is capable in the end behavior, and initial the 0th row of classifying as finish to classify as the m row; When display screen was in the position that shows backward, n was capable for the initial behavior of software setting, end behavior the 1st row, and the initial m row of classifying as finish to classify as the 1st row.
By initial, the end ranks in the display screen 14 are set, can realize 180 degree counter-rotatings of display screen 14 displaying contents, add 180 rotations of runing rest 2, then the shown content of display screen must be a forward.
Second kind, the method for reverse demonstration dot matrix conversion
By extracting display screen 14 displays content data,, and convert the information that extracts to picture element information that every row shows according to display direction and carry out store operation according to display direction information extraction in certain sequence from displays content data of determining.With behavior unit once or be divided into N time (N is an integer) and send into display screen 14, and driving display screen 14 update displayed with the picture element information of preserving.
The algorithmic descriptions of reverse demonstration dot matrix conversion:
The arrangement of forward display buffer is as follows, and wherein, L represents the current capable sum of picture element of depositing content in the display buffer in the internal memory; N represents the byte number of the picture element that the capable multipotency of picture element of display screen shows; K represents first the capable byte of display buffer L picture element in the internal memory; M represents last the capable byte of display buffer L picture element in the internal memory.
1：[1，2，...，N-1，N]
L：[K，K+1，...M-1，M]
Reverse if desired demonstration then needs to arrange the buffer zone in the internal memory as follows:
1：[M，M-1，...K+1，K]
L：[N，N-1，...2，1]
Actual algorithm, for any the byte i in the forward display buffer, be about to the numerical value transposing of its numerical value and [s-(i-1)] individual byte, the buffer zone that will all bytes all be reverse demonstration after the conversion, wherein every some row allowing of the capable sum of picture element (L) * display screen of showing of s=actual needs byte number (N) that can show.
In sum, the Cash collecting equipment of single display screen two directions demonstration of the present utility model can be saved the cost of a cover display screen and control circuit thereof; Simplify the corresponding software design, software only need be controlled the demonstration of a display screen; Display surface is to cashier and client's information on the screen of same equipment, and the estrangement sense in the time of can eliminating customer consumption makes client's sensory information symmetrical and transparent more.
