Abstract

The invention relates to a measurement technique and can be used to create instruments with a light scale, in information regeneration systems on a photosensitive medium, as well as in instruments with mechanical indicators. The invention makes it possible to simplify the device by changing the input information processing algorithm by increasing the functional load on the code conversion units. The device contains three code conversion units, a registration unit, a generator, and EXCLUSIVE OR elements. The indicator of the recorded information occurs in two cycles. At the beginning, the higher bits of the information are displayed, then the younger ones. Due to the corresponding generator frequency, the input information display is a series of luminous lines on the matrix of indicator elements of the recording unit 2 or more.

Description

The invention relates to a measuring technique and can be used to create instruments with a light scale in information recording systems on a photosensitive medium, as well as in instruments with mechanical indicators.

The purpose of the invention is to simplify the device.

FIG. 1 shows a functional diagram of the device; in fig. 2 shows an embodiment of the device block.

The device contains the first, second and third blocks 1-3 conversion codes, block 4 registration, generator 5 pulses, the elements EXCLUSIVE OR 6.

Block 1 contains a converter of 7 codes and the element OR 8.

The device works as follows. The seven-segment code of the number NM mN + M is fed to the inputs of the device. The inputs of block 1 receive the code of the lower bit M,

and the inputs of blocks 2 and 3 are the high-order code N. The device operates in two cycles. Tact A corresponds to the presence of the potential of a logical unit at the output of the clock generator 5, and time tick B corresponds to the potential of a logical zero. At time A, the block converts the code of the number M into an m-bit code combination of the form 11 ... 1, where t is the number of inputs of the least significant Block 4 converts. Block 2 transforms the code of the number N into an n-bit code combination of the 00 010 .. O type, containing a unit at the N + 1 position, block 3 — an n-1-bit code combination of the 00 ... 011 ... 1, containing N units. The first of these combinations is sent to the first inputs of the EXCLUSIVE OR 6 items, and the second to their second inputs. At the second input of the first element 6, a logical unit from the generator 5 is fed. At the outputs of the elements 6, an n-pattern bottom code combination is formed

00 ... 011 ... 1, containing N units. Consequently, in time A, a t-bit code of the form 11 ... 1 is supplied to the inputs of block 4, the least significant code of the type 00., .111 .. 1, containing N units. In time B, block 1 converts the code of the number M into an m-different code combination of the form 00 ... 011 ... 1 containing IVH 1 units. Block 2 transforms the code of the number N into an n-type code combination of the form 00 .., 010. ,, O, containing one at the N + 1 st position, and block 3 - into an n + 1-bit code combination 00 ,,, 0 ,,. The first of these combinations goes to the first inputs of the EXCLUSIVE OR 6 elements, and the second to the second inputs of elements 6. The second input of the first element 6 receives a logical zero from the generator 5. As a result, the outputs of the elements 6 form a n-bottom a code combination of the form 00 ... 010 ,,. О, containing a unit at the N + 1 st position; Consequently, the time combination B of the code combination of the type 00,., 011, ., 1, containing M + 1 units, and the most significant ones - n-bit of the bottom code combination of the form 00 ... 010 ... Oh, content ascha unit at the N + 1-th position. As a result, N full high-order bits of block 4 of mN elements are excited in tact A, and in bit B — N I — and an incomplete most significant bit of No. 1-element. The pulse frequency of the clock generator is chosen so that the receiver of the stump, ermatia, perceives the output sigple in the continuous line m3 mN -i M 1 excited elements of block 4, which corresponds to the conclusion that mN + M,

The device is implemented using s ca1, a basic battery cell of the KYB5 series of chips, and is designed to work with an information recorder on photographic film made on the basis of 128 LED elements included in four unpackaged monolithic multi-element light-emitting lines (see Multiple monolithic linear recording scales) information on the film OR Abdullaev, V.S.

The operation of the device is based on the example of entering the number 37 (128 values are recorded on film; from 000 to 127). The code 01 00111 arrives at the device input. The device operates in two clocks. The clock A corresponds to the presence of the potential of a logical unit at the output of the clock generator 5
