CN2446543Y - Camera back cover with typing keyboard character imaging display window - Google Patents

Abstract

The utility model relates to a camera back cover with a typing keyboard character imaging display window, which comprises a typing keyboard (1) and a liquid display screen LCD (1) (4). When a camera is used for recording pictures, a keyboard switch key on the back cover is pressed and place name where the pictures are taken, date, and year with four bits (3) are struck out through using phonetic input method or other input methods through 33 keys arranged on the keyboard. After Chinese characters, English letters and numbers which are desired are displayed through the LCD (1) display screen (4) and an LCD (2) display screen, the pictures can be taken.

Description

Have keyboard for typewriting literal picture imaging display window camera back

The utility model camera back, have can get any Chinese character, English and digital date with shine scenery and together expose on egative film the function that on photo, shows.

The more advanced bonnet of selling on the market of camera also can only show two times, two months now, does not show but all camera backs all have the address of Chinese, English and four time numerals to take a photograph.The camera photo of breaking forth in the past when others sees, be recalled and introduces and could understand place name, the time and date of taking a photograph by owner.If the time one is long, the photo that has is difficult to recall clear place name at that time, has brought directly perceived, not inconvenient regretting to people.In addition, present printing paper all is shiny surface, and the word of wanting to write with a pen is difficult to, write also reluctantly and wipe easily, even write overleaf, but if release and see being set in photo in photograph album or the picture glass, very inconvenient, and not directly perceived.Concerning the bad people that writes, also be reluctant word is stayed on the photo, also be reluctant the faulty stroke in calligraphy or painting of landscape beautiful on the photo with oneself stained.

The purpose of this utility model is: a kind of camera back that can demonstrate Chinese, English and four time numerals date (as 2000) on photo is provided, thereby has increased the multi-functional of camera, and strengthened the aesthetic feeling memory of being taken a picture.

The utility model has keyboard for typewriting literal picture imaging display window camera back, it is characterized in that: film display window (5) and 33 typing keys (1) and LCD are arranged on the bonnet of camera (6) ₁Display screen (4) constitutes typewriting and display system.Be installed with a double-sided wiring board back side (20), positive (25) on its bonnet inner bottom plating.Liquid crystal display LCD is set respectively on this wiring board ₁And LCD ₂, central processor CPU chip, character base module IC ₁, constitute the literal function control circuit unit.Battery folder (26), bulb (29), reflex reflector lens (27), LCDs LCD ₂(7), LCD ₂Tie point (28), LCD ₂Display/panel bracket (32), exposure box (33) exposure switch via hole (34) and exposure switch two contact points (11) constitute exposure mechanism.When taking pictures, correspondent button on the keypad can be presented at the place name of taking pictures, time and message on the photo, as souvenir.Work as LCD ₁When showing required content, because LCD ₂And LCD ₁Also connect LCD mutually ₂Content displayed and LCD ₁Content displayed is identical, presses shutter, passes through LCD ₂Demonstration exposes to egative film can realize the purpose of literal, numeral and image imaging simultaneously.The time that four times (3) that this machine bonnet shows can solve after 2000 shows.

Owing to adopted above-mentioned technical scheme, on camera back, be provided with keyboard, Chinese character, English and digital date imaging function control module are operated.Be that this camera bonnet has the remarkable advantage that is not had with the current camera bonnet.The compact conformation of this camera bonnet and easy to use.

The utility model is described in further detail below in conjunction with drawings and Examples:

Fig. 1 is a camera back front keyboard distribution plan.

Fig. 2 is the rear view at the camera back back side.

Fig. 3 removes wiring board, backplate, pelleting press, bonnet interior view.

Fig. 4 is the wiring board backplate layout that is assemblied on the camera back.

Fig. 5 is the wiring board front layout that is assemblied on the camera back.

Fig. 6 is the backplate that is assemblied on the camera back, LCD2 support, the composition diagram of exposure box.
