Description

Manuscript log drum for computer

The utility model relates to manuscript bracing frame, support drum or shell shape, computer drive system and the display system of the usefulness of typewriting.

At present, in font typewriter or the computer, the foreign language typewriter is used is the plane pole type support of keeping a foothold, computing machine is a new and high technology, its appearance and remarkable performance thereof, more and more widely be used as the high performance office automation system, but, the bracing frame that matches with computing machine (drum) does not also have literal report, the plane pole type support of keeping a foothold, and its structure adopts plane formula, area occupied is big, manual operation, support can only be placed on plumbous typewriter and in, use still can be gathered together in both sides, the foreign language typewriter left and right sides, if supporting with computing machine, be placed on above or below the computing machine, influence watches computer screen to show and the typing operation, if be placed on the left side or the right of computing machine, sighting distance is too far away, operating personnel need constantly shake the head, frequent page turning, the easiest wrongly written character of seeing wastes time serial with seeing, use very inconvenience, also influence input speed and computing machine high-performance greatly, giving full play to of high-speed superiority.

91211291, No. 3 computer draft drums of patent technology, first design has following shortcoming: external form fails to solve well, the DC circuit poor performance, it is not high to carry out precision, poor for applicability, by the exploitation more than 2 years, significant improvement is arranged at aspects such as external form, type of drive, structures.

The purpose of the type that this practicality is new is: provide that a kind of structure is more reasonable, easy to operate, aesthetic in appearance, computer control, precision height, very suitable, and can improve the new patented technology of input speed greatly.

The utility model adopts following solution: have a main shaft to connect two supports in two supports, one manuscript drum is arranged on main shaft, the magnetic force press strip of one or more is arranged on the manuscript drum or be equipped with driving manuscript paper stage clip bent plate and depression bar more than one and the pinch roller more than with the drum body.

The two stands outside or any bracket outside that are connected with main shaft can add handwheel; Motor of installation and gear set on main shaft make it drive main shaft and manuscript rouses in the desired direction, the rotation of angle accurate timing.

Stepper motor adopts computer program to control with manually combining, and step pitch and second number adopt a LCD(LED) digital display mode, very directly perceived, adjustment, very easy to use.

Shell is installed in drive system and drum body, makes complete machine unified, complete, attractive in appearance.

The utility model compared with prior art has:

1. can press easily and change 8 manuscript paper of opening following all size.

2. with turn clockwise manuscript line feed of motor drives, the regression of can reversing in case of necessity.

3. this manuscript drum is placed on position, the positive front lower place of computing machine, does not promptly influence and watches screen text, does not influence keyboard operation again, and screen, original text, dish are near to be received at the moment, use very convenient, thereby improved computer operator's input speed.

Below in conjunction with accompanying drawing, utility model is described in further detail:

Fig. 1. be the utility model front view.

Fig. 2. be the utility model side view.

Fig. 3. be electric principle system block diagram of the present utility model.

The computer draft of expression drum external form and structure among Fig. 1,2, also be best enforcement of the present utility model, 1. switch, 2. handwheel, 3. casing, 4. read window, 5. the magnetic pressure bar, 6. rouse body (steel plate or rubber roll), 7. right back up pad, 8. gear wheel, 9. charactron, 10. fixing fixedly sieve, 18. motor support plate, 19. motors of sieve, 15. bearings, 16. pinion wheels, 17. of keyswitch, the perforation of 11. electric wires, 12. main shafts, 13. circuit boards, 14..

Among the figure: main shaft 12 is connected with two side stands 7 by manuscript drum 6, and handwheel 2 is fixed on the outer main shaft 12 of shell, magnetic stripe 5, and the 1--2 bar can take off arbitrarily, is pressed on the bulging body 6 by single face suction.

Stepper motor 19 is fixed on the back up pad 18, be connected with main shaft with 16 by one group of gear 8, and a computerized control system and its connection arranged, motor 19 can drive manuscript drum 6 by gear 8 and 16 and regularly rotate by a step number that presets and an interval second number clockwise, when needing, also can realize positive and negative rotation by hand button 10.

The manuscript drum can be garden cylindricality, hexagon, pentagonal prism shape or other shape, can be according to the shape and the length of manuscript drum, on manuscript drum, inhale and press one or two magnetic attraction press strips or depression bar, press strip can rotate with the manuscript drum arbitrarily, can determine the length of press strip or depression bar as required, be suitable for and be as the criterion with convenient, suction, hand pressure bar can press manuscript paper easily.

Manuscript of the present utility model drum is by adjusting size, can with the supporting use of the computing machine of various models, and can with in, foreign language computer typewriter, the supporting use of printer.

What Fig. 3 represented is the circuit block diagram of manuscript drum, be the utility model specialized designs exploitation computer partly, mainly contain 8 ones and partly form: 1. central processing unit, 2. memory under program, 3. circuit interface, 4. digitally show, 5. button, 6. driving circuit, 7, stepper motor, 8, power circuit.

1,2,4,6,8 are made up of integrated circuit and capacitance-resistance unit, device among the figure, are the cores of computer, are contained on the double-sided PCB.

Power circuit 8 is contained in another and specially closes for a short time, and it is far away to leave computing machine, provides low-voltage to complete machine, guaranteed safety.

Display is made up of five charactrons, divide two groups, the step number (line width) of the each stepping of 2 demonstration motors wherein, from the adjusting arbitrarily of 1--99 step, very accurate, three charactrons show a second number in addition, regulate arbitrarily second from 1--999, its step width and control time, all kinds of computing machine typing personnel's needs have been satisfied.

Central processing unit 1 and memory 2 are hearts of circuit, after the start, and the main frame self check, the typing personnel simply transfer machine according to required width that carries out of individual and time, can choose optimal parameter.

Manual change-over switch four blade three is thrown, can set the accent machine (in), automatically (left side) and manual (right side) three gears.

Adjust two of (manually) buttons, adopt keyswitch, bear dual function: 1, adjust step number and second number, 2, manually help into and help and move back.
